A DUVET OR BLANKET AND COVER FOR THE SAME

Abstract

 A duvet or blanket (16), formed of a plurality of sections (52, 54, 56), releasably coupleable together for assembly or disassembly of the duvet or blanket.

Description

FIELD OF THE INVENTION

[0001] This invention relates to a duvet or blanket, and a cover for a duvet or blanket.

BACKGROUND OF THE INVENTION

[0002] Blankets, duvets or quilts are commonly used as insulative coverings when sleeping. When a duvet or blanket is used regularly for sleeping it is common to provide a removable cover over the duvet or blanket, often in the form of a textile sleeve, to protect the duvet or blanket. The cover can be washed without washing the duvet or blanket.

[0003] A common problem encountered with duvets or blankets, especially in cold environments, is that of keeping the extremities, particularly the feet, sufficiently warm. Due to their relative distance from the main centres of heat in the body, these parts often become disproportionately cold under the duvet or blanket, which is uncomfortable, and can disrupt or prevent sleep.

[0004] Various auxiliary devices or accompaniments have been proposed to address this problem, including for instance hot water bottles, heated mattress covers, or simply additional blankets or coverings.

[0005] However all of these solutions add a degree of inconvenience, since they require the provision of additional external units or articles. These often require setting up in advance, and then subsequently require removal and storage when not needed. Their additional bulk when sleeping may also add a further source of discomfort.

[0006] Required is an improved solution to the problem of chill in extremities when sleeping with a duvet or blanket.

SUMMARY OF THE INVENTION

[0007] The invention is defined by the claims.

[0008] According to an aspect of the invention, there is provided a removable cover for a duvet or blanket, comprising:

a sleeve article for receiving the duvet or blanket, the sleeve article having opposed elongate edges for coinciding with side elongate edges of the duvet or blanket when received in the sleeve article,

each elongate edge comprising first and second edge-fastening sections of corresponding length with complementary couplings, and spaced apart from one another by an intermediate gap section, and

wherein, in use, a duvet or blanket received within the cover may be folded via said intermediate gap section, to bring the edge-fastening sections on each edge into overlap, and form a pocket in the duvet or blanket, the overlapping edge-fastening sections permitting securing of the duvet or blanket in the folded position, to prevent unfolding of the formed pocket.

[0009] The invention provides a duvet or blanket cover with a novel arrangement of complementary fastener sections on edge parts of the cover which permit a pocket to be quickly and easily formed in the duvet by simply folding the duvet back on itself in a zigzag fashion about the intermediate gap section and coupling the overlapping fastener sections together. This forms a pocket beneath the main body of the duvet into which the feet may be inserted for additional insulation. The pocket ensures that the feet are closely wrapped or enveloped on both sides, better insulating them against the cold.

[0010] Since the pocket is formed entirely by the duvet itself, no additional articles or devices are needed, which makes the solution very simple and convenient for a user.

[0011] Furthermore, since the pocket is formed simply by coupling integrated fastener sections, the pocket can be easily and rapidly removed simply by uncoupling the fastener sections.

[0012] An additional benefit of the invention, even where a pocket is not required, is the ability to easily and quickly shorten the length of a duvet. This permits a duvet length to be adjusted to a size of a bed.

[0013] With the duvet or blanket folded to form the pocket, the duvet or blanket can be secured in position using the overlapping edge-fastening sections, in particular by fastening the (overlapping) complementary coupling parts (on each side) to close or secure the edge-fastenings, and couple the overlapping fastening sections together.

[0014] Hence, in use, a duvet received with the cover is configurable in two modes: an open mode in which the duvet is open and may be laid flat, and a pocket mode in which the duvet is folded in zigzag fashion via said intermediate gap section to form a pocket in the duvet and the edge-fastening sections coupled together to retain the pocket in place.

[0015] The complementary couplings may be couplings which engage or interact or co-operate to permit releasable fastening together of the edge-fastening sections. Complementary couplings may also be referred to as co-operative couplings.

[0016] The couplings provide a releasable coupling means, permitting releasable fastening together of the overlapped first and second edge fastener sections.

[0017] The couplings may permit marrying of the overlapping edge-fastening sections together, by which is meant the overlapping edge-fastening sections are closed together along a continuous coupling line.

[0018] The couplings may for instance permit sealing of the first and second edge-fastening sections together. Sealing means forming a continuous closed coupling. This better insulates the feet against cold air in the environment. The sealing does not however need to be airtight (i.e. hermetic).

[0019] The first and second edge-fastening sections of each elongate edge form a pair of edge-fastening sections, in particular a complementary pair or co-operating pair of edge-fastening sections.

[0020] There is at least a first and second edge-fastening section on each elongate edge of the sleeve article. In some examples, there may further be provided additional pairs of edge fasting sections on one (or preferably) both of the elongate edges. This allows a pocket to be formed in any of a plurality of locations in the duvet. This adds flexibility.

[0021] More than one coupling element or means may be provided along one or more of the edge-fastening sections in some examples, to allow the respective edge fastening sections to couple to more than one other edge fastening section simultaneously. More than two edge-fastening sections may be provided along each elongate edge in this case for instance.

[0022] For example in some examples, three edge fastening sections may be provided along each elongate edge, each separated from its neighbour by an intermediate gap section. In this example, an upper and lower coupling element or means or part may be provided along a middle one of the edge-fastening sections to allow that edge fastening section to extend co-extensive with a middle layer surface part of a formed pocket and to couple simultaneously with the other two edge-fastening sections, these for extending along edges of an lower and upper surface part of a formed pocket respectively.

[0023] Reference to elongate edges means edges which extend at least generally along a lengthwise dimension of the sleeve article, i.e. a longer of the dimensions of the sleeve article (longer than a transverse width-wise dimension).

[0024] The elongate edges are preferably parallel, i.e. extend parallel with one another. The sleeve article may be rectangular for example.

[0025] Corresponding length may mean of substantially equal length, for example equal length.

[0026] Substantially equal length may simply be referred to as equal length, meaning equal length plus or minus normal tolerances, for example small differences being immaterial to the functioning of the invention.

[0027] The intermediate gap section preferably has a length equal to or greater than the (common) length of the first and second edge-fastening sections.

[0028] This allows for a folded formation for instance in which the portion of the cover co-extensive with the first and second edge fastening sections form upper and lower surfaces of the pocket and the intermediate gap section of the cover is sandwiched in-between. In this configuration, the defined minimum length of the intermediate gap section allows that the removable cover (and received duvet or blanket) may be folded back far enough for the first and second edge-fastening sections to be brought into alignment/registration with one another, i.e. so that they are fully overlapping, and with the intermediate gap section sandwiched in-between. If the intermediate gap section were shorter than this length, and the intermediate gap section were to be sandwiched in-between to form a middle layer of the pocket, the edge-fastening sections could only be brought into partial overlap, preventing them from fully or properly mating.

[0029] In further examples however, the length of the intermediate gap section may be shorter than that of each of the first and second edge fastening sections. This may allow for instance for further folded configurations, for instance a greater number of edge fastening sections are provided, and the edge fastening sections extend along edges of a top and bottom surface of the pocket as well as middle layer of the pocket. The intermediate gap section may then extend along a U-turn portion of the pocket when in the folded configuration.

[0030] In some examples, the sleeve may be a textile sleeve, e.g. a fabric sleeve.

[0031] In a preferred set of embodiments, the edge-fastening sections of one elongate edge may be aligned with those of the other elongate edge, i.e. the edge-fastening sections of the two edges are aligned or are in registration.

[0032] Each edge-fastening section on one of the elongate edges is in this case aligned with the (corresponding) edge-fastening section on the opposing elongate edge.

[0033] According to some examples, the intermediate gap section on each elongate edge may have a longer length than that of each of the edge-fastening sections. Any length longer than that of the first and second edge-fastening sections may be provided in this case.

[0034] Providing a longer length may allow a single-fold pocket to be formed which is longer than the length of the edge-fastening sections. This longer length pocket may thus protrude from the ends of the overlapped edge-fastening sections. This may increase stability of the pocket, since the portion of the pocket protruding from the ends of the edge fastening sections helps to retain the pocket in place, and makes dislodging and unfolding of the pocket less likely.

[0035] The length of the intermediate gap section may in some examples be an odd integer multiple of said length of each of the first and second edge-fastening sections, i.e. 1, 3, 5 or 7 etc. times said length. In this way, the pocket may be folded about itself at said intermediate gap section either once, or more than once, to thicken and better insulate the pocket, but in all cases such that the duvet may be brought back facing the right direction. This will be illustrated more clearly with reference to the figures in the following section.

[0036] The length of the intermediate gap section may in some examples be equal to said length of the first and second edge-fastening sections. This allows for a single-fold pocket to be formed. For the reasons explained above, a length equal to that of the edge fastening sections is the minimum necessary to ensure full overlap of the edge fastening sections can be achieved, with the duvet folded back facing the right direction. This arrangement minimises the overall length of the duvet cover and received duvet which may be move convenient for a user (e.g. for storage) and also minimises required material and hence cost.

[0037] In accordance with one or more embodiments, the sleeve article may comprise an upper pouch section for receiving the duvet or blanket in use, and a lower flap section for folding beneath a mattress upon which the duvet or blanket is placed in use.

[0038] The upper section for instance forms one end of the sleeve article, and the lower section forms a second end. The flap section forms a tail of the sleeve article for folding beneath a mattress or other body or structure upon which the duvet or blanket received in the pouch is placed.

[0039] Preferably a stop means is disposed between the pouch and flap sections for preventing travel of a duvet or blanket received in the pouch section from the pouch section into the flap section.

[0040] The stop means prevents the duvet riding down into the flap section.

[0041] In certain examples, the stop means may comprise a seam, preferably extending across a width of the sleeve, from one elongate edge of the sleeve to the other.

[0042] The seam may however extend across only a portion of the width of the duvet. The seam may be formed of multiple separated sections. For example, the seam may comprise two seam sections, extending inwardly from the opposing elongate edges.

[0043] Width refers to the dimension extending cross-wise between the elongate edges, e.g. perpendicular to these edges, e.g. perpendicular to the length.

[0044] Preferably each edge-fastening section comprises one or more coupling elements disposed along the full length of the respective section (i.e. occupying the length of the respective section), to permit fastening along the entire length of the section. The coupling elements may hence occupy each edge fastening section from one end of the section to the other.

[0045] The complementary couplings may be complementary zip parts. A zip coupling permits marrying of the edge fastening sections together, i.e. in sealing fashion, i.e. forming a continuous closed coupling.

[0046] The complementary couplings may in other examples comprise for instance button-couplings, or popper couplings or any other form of coupling or fastening means.

[0047] The first and second edge-fastening sections of each opposed edge may preferably be located in a same end half of the sleeve article.

[0048] This means that the first and second edge-fastening sections of both of the opposed edges are located within the same end half.

[0049] In some examples, all of the edge-fastening sections of the removable cover may be located within same end half of the cover.

[0050] However, in other examples there may be provided one or more additional pairs of edge fastening sections located in the alternative half.

[0051] In the case that the removable cover comprises a pouch section and flap section, as set out above, the first and second edge-fastening sections of each opposed edge may be located along edges of said pouch section. Since the pouch section receives the duvet or blanket, this arrangement ensures that the pocket is formed in the region containing the duvet or blanket. This ensures the pocket is formed from the duvet or blanket (and so is maximally insulative), rather than formed simply from the material of the sleeve article.

[0052] A related aspect of the invention provides a method of reversibly forming a pocket in a duvet or blanket, the duvet or blanket being received within a removable cover, the removable cover comprising

a sleeve article for receiving the duvet or blanket, the sleeve article having opposed elongate edges for coinciding with side elongate edges of the duvet or blanket when received in the sleeve article,

each elongate edge comprising first and second edge-fastening sections of corresponding length with complementary couplings, and spaced apart from one another by an intermediate gap section, and

the method comprising:
folding the duvet or blanket received within the cover in zigzag fashion via said intermediate gap section, to bring the edge-fastening sections on each edge into overlap, and form a pocket in the duvet or blanket, the overlapping edge-fastening sections permitting securing of the duvet or blanket in the folded position, to prevent unfolding of the formed pocket.

[0053] The intermediate gap section preferably has a length equal to or greater than said length of the first and second edge-fastening sections.

[0054] Examples in accordance with a separate aspect provide a duvet or blanket, formed of a plurality of sections, releasably coupleable together for assembly or disassembly of the duvet or blanket, wherein said sections include:

two end sections, each of a trapezium shape, comprising a straight edge for forming an end edge of the duvet, a pair of parallel edges joining the straight edge for forming sections of side edges of the duvet, and a slanted edge opposing the straight edge, and

at least one triangular middle section, having a base edge for forming a further section of a side edge of the duvet, and two opposed slanted edges extending from the base edge having slant angles complementary to one another and to the slanted edges of the similar end sections, thereby permitting tessellation of the at least one triangular middle section with the end sections to form the assembled duvet.

[0055] The duvet or blanket preferably further comprises edge fasteners at coupling edges of the plurality of sections for coupling the sections together to form the assembled duvet or blanket.

[0056] The duvet or blanket preferably comprises edge fasteners at the slanted edges for coupling the sections together via the slanted edges to form the assembled duvet or blanket.

[0057] The defined construction naturally means that the slanted edges of the end sections are slanted or inclined relative to the straight edges of these sections which form end edges of the duvet, i.e. they slant toward/away from these edges. Since the sections are coupled via these slanted edges, this means that the coupling or fastening joins of the duvet are inclined or slanted relative to the ends of the assembled duvet. Consequently the joins are made structurally stronger to any pulling forces applied from the ends of the duvet, since such forces are partially distributed along the lengths of the joins (i.e. parallel with the joins), as opposed to being applied purely perpendicular to the joins, e.g. in the case of rectangular panel sections.

[0058] This means pulling forces from the end(s) of the assembled duvet or blanket are distributed in two dimensions across the joins instead of one, improving the strength of joins against such pulling forces.

[0059] Puling forces from the ends of the duvet naturally occur during normal use as a user covered by the duvet or blanket adjusts its placement over them via manipulation from one end of the duvet or blanket. Thus resilience against such pulling forces represents a key advantage for multiple sectioned duvets.

[0060] Furthermore, the provision of end sections in a trapezium shape, as opposed for example to a triangular shape which might also include a slanted joining edge, further improves strength of the coupling joins by reducing the total length of the coupling edge. This is because the slanted edge leads from the end of one of the parallel side edges, rather than from the end edge, this side edge traversing some of the length of the section. This length of the section thus does not need to be traversed by the slanted edge, and the slanted edge can be shorter.

[0061] Reducing the length of the slanted coupling edge reduces the total area across which breakage of a join might occur, and thus improves stability and reliability of the join. The longer the join, the greater the chance of a weak patch arising.

[0062] Thus the trapezium shape provides an advantageous balance between providing a slanted coupling edge, and so spreading distribution of force across multiple dimensions, and minimising the length of the join to improve join reliability and integrity.

[0063] The end sections may be similar, i.e. be of the same shape. The end sections may have the same dimensions.

[0064] Complementary slant angles may mean for instance reciprocal slant angles, i.e. equal angles, but with the edges slanting in opposite, and complementary, directions so that one edge may meet in tessellating fashion with another.

[0065] In an advantageous set of examples, the plurality of sections of the duvet or blanket may be releasably coupleable by means of magnetic edge fasteners.

[0066] Complementary magnetic edge fastener parts may be provided on coupling edges.

[0067] The magnetic edge fasteners may be provided along the complementary slanted edges for example.

[0068] According to certain advantageous examples, the magnetic edge fasteners may include a tongue and groove slider arrangement, a tongue part along an edge of one section being slidably receivable within a complementary groove along an edge of a further section, magnetic coupling means being provided between the tongue and groove.

[0069] Magnetic couplings are provided between the tongue and groove for retaining the edges together.

[0070] The tongue and groove may be an interlocking tongue and groove to mechanically retain the edges together, i.e. to prevent pulling of the edges apart. They hence slidably interlock to hold the edges together, i.e. they may interlock upon sliding together.

[0071] A further aspect of the invention provides a kit of parts comprising: a removable cover for a duvet or blanket in accordance with any of the examples or embodiments outlined above or described below, or as set out in any claim of this application, and a duvet or blanket for receipt within said cover.

[0072] The duvet or blanket has dimensions configured to fit inside the cover, with elongate edges extending coincident with the elongate edges of the cover. The dimensions of the duvet or blanket may be such that the duvet fills at least a portion of the sleeve article which is for receiving the duvet or blanket (e.g. said pouch section in the specific example detailed above). The duvet or blanket may be dimensioned such that end edges of the duvet or blanket extend coincident with end edges of at least a portion of the sleeve article for receiving the duvet or blanket.

[0073] In specific examples, the duvet or blanket may be a duvet or blanket in accordance with any of the particular examples or embodiments outlined above or described below, or set out in any claim of this application.

[0074] A further aspect of the present invention provides a duvet or blanket assembly, comprising: a removable cover in accordance with any of the examples or embodiments outlined above or described below, or in accordance with any claim of this application; and a duvet or blanket received within said cover.

[0075] In particular examples, said duvet or blanket may be a duvet or blanket in accordance with any of the examples or embodiments outlined above or described below, or in accordance with any claim of this application.

[0076] The duvet or blanket received within the cover may be in a configuration in which it is folded via the intermediate gap section, to bring the edge-fastening sections on each edge into overlap, and form a pocket in the duvet or blanket, the overlapping edge-fastening sections permitting securing of the duvet or blanket in the folded position, to prevent unfolding of the formed pocket

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0078] The invention will be described with reference to the Figures.

[0079] It should be understood that the detailed description and specific examples, while indicating exemplary embodiments of the apparatus, systems and methods, are intended for purposes of illustration only and are not intended to limit the scope of the invention. These and other features, aspects, and advantages of the apparatus, systems and methods of the present invention will become better understood from the following description, appended claims, and accompanying drawings. It should be understood that the Figures are merely schematic and are not drawn to scale. It should also be understood that the same reference numerals are used throughout the Figures to indicate the same or similar parts.

[0080] The invention provides a removable cover for a duvet or blanket having on each of two opposing elongate edges a respective pair of complementary edge fastening sections of corresponding length, separated by an intermediate gap section, and wherein in use a duvet received in the cover may be folded back on itself in zig-zag fashion via the intermediate gap section so as to bring the fastening sections into overlap and alignment, and form a pocket via the intermediate gap section. By fastening the overlapping fastening sections together on each elongate edge, the pocket may be retained in place without unfolding. The pocket provides a means for better insulating extremities such as the feet from the cold.

[0081] The gap section may in some examples be at least as long as each of the edge-fastening sections.

[0082] The invention relates to a cover for a duvet or blanket or quilt or any other similar insulative covering. For brevity, in descriptions to follow, the cover may be referred to as simply a duvet cover, and the received duvet or blanket referred to as simply a duvet. This is purely illustrative of the concept and does not limit the invention to only use with or for a duvet. In all cases other forms of insulative covering may also be used with the cover.

[0083] A first example removable cover for a duvet or blanket in accordance with one or more embodiments is schematically illustrated in Figs. 1-4. Fig. 1 shows a top-down view of the cover. Fig. 2 shows a cross-sectional side view through the cover having a duvet or blanket 16 received within the cover in use. Fig. 3 shows the cover in use with a duvet or blanket received within the cover and illustrates folding of a duvet or blanket received in the cover so as to form a pocket. Fig 4 shows a perspective view of folding of the duvet or blanket received in the cover to form a pocket and illustrates coupling of the fastening sections to secure the pocket in place.

[0084] The removable cover comprises a sleeve article 14 which forms a main body of the cover, the sleeve article having an interior space or cavity for receiving a duvet or blanket in use, for covering the duvet or blanket. The sleeve article has at least one (preferably releasably closable) open end for receiving the duvet or blanket. The sleeve article comprises first 18 and second 20 opposed elongate edges arranged for coinciding with the side elongate edges of the duvet or blanket 16 when received in the sleeve article.

[0085] Each elongate edge 18, 20 of the sleeve article features first 22 and second 26 edge-fastening sections of corresponding length (i.e. equal or substantially equal length) and having mutually complementary couplings, and spaced apart from one another by an intermediate gap section 24. The edge fastening sections on the two elongate edges are positioned in alignment (i.e. in registration with one another), i.e. the first and second edge fastening section of the first elongate edge are in alignment with the first and second edge fastening section respectively of the second elongate edge.

[0086] Each edge fastening section 22, 26 on each elongate edge 18, 20 comprises couplings 34 or fastening means, complementary to the couplings of the other edge-fastening section on that elongate edge. These couplings extend along the length of the edge fastening section. In the particular example of Figs. 1-4, the couplings are complementary zip parts, i.e. complementary strips of engageable zip teeth. This hence provides a single continuous coupling means 34 extending along the whole length of each edge-fastening section.

[0087] In other examples, a different coupling means 34 may be provided, either for example a different continuous coupling means, e.g. complementary Velcro strips along the edge-fastening sections, or for instance a spaced arrangement of coupling means (e.g. buttons or poppers) may be provided extending along the whole length of each edge-fastening section for instance.

[0088] The intermediate gap section 24 has a length substantially equal to or greater than the length of the first and second edge-fastening sections 22, 26 (i.e. a length corresponding to the length of each of the first and second edge-fastening sections). In the particular example shown in Fig. 1, the intermediate gap section has a length substantially equal to the length of the first and second edge fastening sections. This allows a single fold pocket to be formed in use, by folding a duvet received within the sleeve article back on itself once via the intermediate gap section, and then back again, over the top of the intermediate gap section. The thus formed pocket has a length equal to the length of the intermediate gap section.

[0089] In the particular example of Figs. 1-4, the sleeve article 14 of the removable cover comprises two major sections: an upper pouch section 30 for receiving the duvet or blanket in use and a joined lower flap section 32. Preferably the two are integrally joined, i.e. form portions of a single piece or article. Note that Fig. 2 shows only the pouch section in detail.

[0090] The pouch section 30 and flap section 32 are at least partially separated or bounded by a stop means disposed between the two sections. The stop means prevents the duvet received within the pouch section 30 from riding (travelling) down into the flap section. The stop means in the present example is provided in the form of a seam 28 formed across the width of the sleeve article 14 from one elongate edge 18 to the other 20. Extension of the seam across the whole width of the cover is not essential. In other examples a seam may be provided for instance comprising two seam sections extending inwardly from the first and second elongate edges part way toward the middle of the sleeve article 14.

[0091] The two edge-fastening sections 22, 26 on each side are both located on edges of the pouch section 30, in particular at a lower end region of the pouch section. This ensures that in use a pocket can be formed in the portion of the cover with the duvet or blanket received within it.

[0092] The flap section 32 is for engaging with another entity for use in anchoring or positioning the cover, with the duvet or blanket received in it, in use. For example, the flap may be folded beneath a mattress 44 upon which the covered duvet or blanket is placed, to better hold the duvet and the formed pocket in position. This is illustrated in Fig. 3 which will be described further below.

[0093] In use, a duvet or blanket 16 received within the removable cover may be folded via said intermediate gap section 24, to bring the edge-fastening sections 22, 26 on each edge into overlap, and form a pocket in the duvet or blanket. This is illustrated in Fig. 3.

[0094] Fig. 3 shows a schematic side view of the cover in use with a duvet or blanket 16 received within the sleeve article 14. The thus covered duvet or blanket forms a duvet or blanket assembly comprising both the cover and the covered duvet or blanket. The covered duvet or blanket is illustrated lying on a mattress 44 of a bed.

[0095] A pocket 40 is formed in the duvet by folding the duvet back on itself in zig-zag fashion via the portion of the duvet and cover being co-extensive with the intermediate gap sections 24 of the sleeve article 14 edges 18, 20.

[0096] As shown, a first U-shaped fold is formed at the boundary between the intermediate gap sections 24 on each side edge and the first edge-fastening sections 22 on each side edge, turning the duvet back on itself over the top of the portion of the duvet and cover co-extensive with the first edge-fastening sections 22. A second U-shape fold is then formed at the opposite boundary, between the intermediate gap sections 24 and the second edge-fastening sections 26, turning the duvet and cover back on itself again, and over the top of the previously folded portion of the duvet and cover co-extensive with the intermediate gap sections.

[0097] These two U-shaped folds thus together define a zig-zag formation in which the first and second edge-fastening sections are brought into overlap with one another (preferably into exact or complete overlap, i.e. into alignment).

[0098] The folding configuration thus forms a pocket in the duvet, upper and lower bounding faces of the pocket being formed by the portion of the duvet and cover co-extensive with the second edge-fastening sections 26 and intermediate gap sections 24 respectively.

[0099] Although not explicitly shown in Fig. 3, by fastening together the overlapping edge-fastening sections on each side of the cover, the duvet or blanket 16 may thus be secured in the folded configuration, to prevent unfolding of the formed pocket 40.

[0100] This is illustrated more clearly in Fig. 4 which shows a perspective view of the cover in use with a duvet or blanket 16 received within the sleeve article 14. Fig. 4 shows the duvet in a folded configuration so as to form a pocket and illustrates with arrows 50 how the complementary couplings along the first 22 and second 26 edge fastening sections are coupled together around the intermediate gap section sandwiched between the sections.

[0101] For ease of illustration, Fig. 4 shows the duvet or blanket received in the cover as relatively stiff and inflexible to bending and compression. However, as will be apparent, in the case of most duvets and blankets, the body of the body of the duvet or blanket is very soft, flexible and compressible, allowing for a folded configuration such as that shown in Fig. 4 to be formed without undue bulk. Furthermore, this flexibility and compressibility also allows for the edge-fastening sections 22, 26 to be coupled together around the outside of the intermediate gap section (as indicated by arrows 50) without causing undue bulging or stress in the duvet or blanket body.

[0102] There is at least a first 22 and second 26 edge-fastening section on each elongate edge 18, 20 of the sleeve article 14. In some examples, there may further be provided edge fasting sections on one (or preferably) both of the elongate edges. This allows a pocket to be formed in any of a plurality of locations in the duvet.

[0103] For example, a first pair of complementary edge-fastening sections may be provided on each edge in one end half of the sleeve (the pairs preferably in alignment with one another), and a further pair of complementary edge-fastening sections provided on each edge in a second end half (and the pairs preferably in alignment with one another). Depending upon the locations, this might allow a user to choose at which end to form the pocket. This adds flexibility, as a foot pocket can always be formed no matter which way up the duvet or cover is used.

[0104] More than one pocket might also be formed at the same time where multiple pairs of edge-fastening sections are provided. For example, if appropriately positioned, multiple pairs of edge-fastening sections may permit one pocket to be formed near the feet, for insulating the feet, and a further pocket to be formed near the hands, for insulating the hands.

[0105] In the example of Figs. 1-4, for each of the elongate edges 18, 20, the intermediate gap section 24 is substantially the same length as each of the first 22 and second 26 fastening section. As described above, this allows a single fold pocket to be formed in use, by folding a duvet received within the sleeve article back on itself once via the intermediate gap section, and then back again, over the top of the intermediate gap section. More particularly, it allows such a single fold pocket to be formed which is of the same length as the first and second edge-fastening portions.

[0106] According to further examples, the intermediate gap section 24 on each elongate edge may have a longer length than that of each of the edge-fastening sections. Any length longer than that of the first and second edge-fastening sections may be provided.

[0107] Providing a longer length may allow a single-fold pocket to be formed which is longer than the length of the edge-fastening sections. This longer length pocket may thus protrude from the ends of the overlapped edge-fastening sections. This may increase stability of the pocket, since the portion of the pocket protruding from the ends of the edge fastening sections helps to retain the pocket in place, and makes dislodging and unfolding of the pocket less likely.

[0108] In some examples, the longer length may permit a multiple-fold pocket to be formed. In some examples, the length of the intermediate gap section may be provided as an odd integer multiple of said length of each of the first and second edge-fastening sections. This allows a multiple fold pocket to be formed, with each folded portion of the intermediate gap section having a length substantially equal to a length of each of the first and section edge-fastening portions.

[0109] In further examples still, the intermediate gap section 24 may be shorter than the length of each of the first and second edge-fastening sections. This allows for instance for a configuration in which an edge-fastening section extends co-extensive with a middle layer section of the pocket.

[0110] An example is shown in Fig. 5. Here for instance, the first 22 and second 26 edge fastening sections extend along edges of an upper surface and a middle layer surface respectively of the formed pocket. The intermediate gap section 24 extends co-extensive with a portion of the sleeve article 14 and received duvet 16 which forms a U-turn connecting this upper surface and middle layer. A further (third) pair of edge fastening sections 27 extends along edges either side of a lower surface portion of the formed pocket.

[0111] The second 26 edge fastening section includes lower 34c and upper 34b coupling parts for coupling (when folded) in complementary fashion with coupling parts 34d, 34a of the third 27 and first 22 edge-fastening sections respectively, these extending along a lower and upper surface portion of the formed pocket respectively.

[0112] This allows a middle layer part of the pocket to contribute to the coupling together of the edges of the formed pocket, thus relieving the force exerted on the coupling parts on the upper and lower surface parts of the pocket.

[0113] The coupling means 34 in the example of Figs. 1-4, and in the example of Fig. 5, comprise complementary zip parts. In more detail, the two edge-fastening sections (22, 26) on each elongate edge (18, 20) comprise (mutually) complementary strips of zip teeth configured to couple together through progressive engagement of teeth starting from a first end of each of the strips and ending at a second end. Each fastening section preferably comprises a single continuous zip strip. For each elongate edge, the zip strips of the first and second edge-fastening sections are arranged in series, with the second (finishing) end of the strip of one edge-fastening section facing or pointing in the direction of the first (starting) end of the strip of the other edge-fastening section.

[0114] According to any embodiment, there may be incorporated into the duvet cover a sleep aid composition or substance, such as an aromatherapy essential oil, for aiding sleep of a user. Aromatherapy essential oils for example are known to help with inducing sleep and also to enhance the quality of sleep.

[0115] The sleep aid composition may for example be provided suffused, embedded, impregnated or otherwise incorporated into at least a portion of the material of the duvet cover. The duvet cover may in some examples include one or more dedicated material portions for impregnating or otherwise incorporating with one or more sleep aid compositions. In some examples the sleep aid composition may be incorporated, e.g. impregnated, into the material of substantially the whole of the duvet cover.

[0116] By way of one example, the sleep aid composition may be a lavender aromatherapy essential oil.

[0117] At least the portion of the sleeve article 14 which is for receiving a duvet or blanket in use, e.g. the pouch section 30 in the example of Fig. 1 may have a length which is longer than a standard length for at least one of a King Size, Queen Size, Double or Single duvet in the United Kingdom. This extra length allows for a pocket to be formed in the duvet when received in the sleeve article without shortening the (duvet receiving portion of) the removable cover relative to its normal size for a bed.

[0118] In some cases, at least the portion of the sleeve article 14 which is for receiving a duvet or blanket in use, e.g. the pouch section 30 in the example of Fig. 1 may have a length which is longer than a standard length for a double or single duvet in the United Kingdom, i.e. longer than approximately 200 cm.

[0119] The duvet-receiving portion of the sleeve article 14 may for example have a length which is from approximately a sixth to approximately a third longer than the standard length for a single or double duvet in the United Kingdom, i.e. may have a length from approximately 230 cm to approximately 270 cm.

[0120] More preferably, the duvet-receiving portion of the sleeve article 14 may have a length for example which is from approximately a fifth to approximately a third longer than the standard length for a single or double duvet in the United Kingdom, i.e. may have a length from approximately 240 cm to approximately 270 cm.

[0121] More preferably still, the duvet-receiving portion of the sleeve article 14 may have a length which is from approximately a quarter to approximately a third longer than the standard length for a single or double duvet in the United Kingdom, i.e. may have a length from approximately 250 cm to approximately 270 cm.

[0122] Most preferably, the duvet-receiving portion of the sleeve article 14 may have a length which is approximately a quarter longer than the standard length for a single or double duvet in the United Kingdom, i.e. may have a length of approximately 250 cm.

[0123] A further aspect further provides a duvet or blanket, formed of a plurality of sections, releasably coupleable together for assembly or disassembly of the duvet or blanket.

[0124] Fig. 6 schematically illustrates an example duvet or blanket 16 in accordance with one or more embodiments of this aspect.

[0125] The example of Fig. 6 is formed of three sections. Other examples may comprise more than three sections. For instance more triangular middle sections may be provided.

[0126] In accordance with the present examples, the sections of the duvet or blanket 16 include two similar end sections 52, 54, each of a trapezium shape, each comprising a straight edge 62 for forming an end edge of the duvet or blanket, a pair of parallel edges 64a, 64b leading from end of the straight edge for forming sections of side edges of the duvet or blanket, and a slanted edge 68 opposing the straight edge.

[0127] Disposed between the two end sections is one triangular middle section 56, having a base edge 72 for forming a further section of a side edge of the duvet or blanket, and two opposed slanted edges 74a, 74b extending from the base edge and having slant angles complementary to one another and to the slanted edges of the similar end sections. The complementarity of the slant angles thereby permits tessellation of the triangular middle section with the end sections in order to form the assembled duvet or blanket.

[0128] The duvet or blanket 16 further comprises edge fasteners 78 at coupling edges of the plurality of sections 52, 54, 56 for coupling the sections together to form the duvet or blanket. In particular the duvet or blanket comprises edge fasteners at the slanted edges 68, 74 for coupling the sections together via the slanted edges to form the assembled duvet or blanket.

[0129] The edge fasteners each comprise complementary coupling parts provided on the coupling edges, i.e. each two coupling edges having couplings complementary to one another.

[0130] Each pair of coupling slanted edges (i.e. edge 68a and 74a and edge 68b and 74b in the example) includes a first coupling part on one of the edges and a second complementary coupling part of the other of the edges. These are not illustrated in detail in Fig. 6.

[0131] In an advantageous set of examples, the edge fasteners are magnetic edge fasteners. In this case, complementary magnetic edge fastener parts may be provided on coupling edges.

[0132] The magnetic edge-fasteners may for example comprise complementary magnetic elements provided on coupling edges of the sections.

[0133] The magnetic edge fasteners may be provided along the complementary slanted edges for example.

[0134] The magnetic edge fasteners may take any suitable form. For example, the magnetic edge fasteners may comprise complementary magnetic elements integrated (e.g. sewn) into coupling edges of the duvet sections. This may for example comprise a set of magnets provided (e.g. sewn in) along each coupling edge, for instance spaced apart from each other along each edge. The magnets on the two edges may be coupled together in magnetic attractive fashion to removably secure the duvet sections together. The magnetic elements may be arranged at the coupling edges such that the duvet coupling edges couple together in at least partial overlapping fashion, with the magnetic couplings securing the overlapped edges to one another.

[0135] Fig. 7 schematically illustrates such an example arrangement. Edge fasteners in the form of complementary magnetic elements 78 are provided sewn into and along respective coupling edges 74a, 68a of each of two illustrated duvet sections. By way of illustration, the arrangement is shown illustrated for complementary slanted edges 68a, 74a of the first end section 52 and triangular middle section 56 of the example duvet of Fig. 6. The left-hand image in Fig. 7 shows the arrangement of magnetic elements 78 sewn into one 74a of the two coupling edges. The right-hand image illustrates coupling of the two edges together via the magnetic fasteners.

[0136] When the coupling edges are brought together, the complementary sets of magnetic elements 78 on the two coupling edges 74a, 68a attract one another, thereby forming a coupling between the two which acts to secure the two duvet sections 52, 56 together. The duvet sections may be detached from one another by simply pulling the coupling edges apart with sufficient force to overcome the magnetic attraction between the magnetic elements of the two edges.

[0137] The magnets 78 in each coupling edge are arranged such that the two coupling edges may be secured together in partial overlapping fashion. This is schematically illustrated in Fig. 8 for example. This may be facilitated for instance by orienting the magnetic elements along each coupling edge such that the magnetic field lines of each magnetic element are vertically orientated (i.e. orientated in a direction perpendicular to the plane of the duvet section). The magnetic elements of the two edges should also for this purpose have their respective magnetic poles oriented such that magnetic elements of two overlapping coupling edges mutually attract one another.

[0138] In the above description and figures, the example magnetic edge fastener arrangement is shown in respect only of two slanted edges 74a, 68a of the first end duvet section 52 and middle triangular duvet section 56. However, this is by way of illustrative example only. The same arrangement may be incorporated into any other pair of coupling edges of the duvet, for example the slanted edges 68b, 74b of the second end duvet section 54 and middle triangular duvet section 56 respectively.

[0139] The magnetic elements may include for instance button magnets, strip magnets, bar magnets or any other kind of magnetic element.

[0140] According to certain advantageous examples, the magnetic edge fasteners may include a tongue and groove slider arrangement, a tongue part along an edge of one section being slidably receivable within a complementary groove along an edge of a further section, magnetic coupling means being provided between the tongue and groove.

[0141] Magnetic couplings are provided between the tongue and groove for retaining the edges together. These may include for instance magnetic strips, or magnetic pieces or any other kind of magnetic element or coupling.

[0142] The tongue and groove may be an interlocking tongue and groove to mechanically retain the edges together, i.e. to prevent pulling of the edges apart. They hence slidably interlock to hold the edges together, i.e. they may interlock upon sliding together.

[0143] Magnetic edge fasteners represent just one example. In other examples, the edge fasteners may take any other form, for example zip fastenings, button fastenings, clasp fastenings or any other kind of fastening means. The edge fastenings may comprise any means suitable for securing the duvet edges together.

[0144] According to one or more example embodiments, there may be incorporated into the duvet a sleep aid composition or substance, such as an aromatherapy essential oil, for aiding sleep of a user. Aromatherapy essential oils are known to help with inducing sleep and also to enhance the quality of sleep for example.

[0145] The sleep aid composition may for example be provided suffused, embedded, impregnated or otherwise incorporated into at least a portion of the material of the duvet. The duvet may in some examples include one or more dedicated material portions for impregnating or otherwise incorporating with one or more sleep aid compositions. In some examples the sleep aid composition may be incorporated, e.g. impregnated, into the material of substantially the whole of the duvet.

[0146] By way of one example, the sleep aid composition may be a lavender aromatherapy essential oil.

[0147] One 64b (the longer) of the parallel edges of each of the end sections 52, 54 may have a length equal to half of the total length of the assembled duvet or blanket.

[0148] One 64a (the shorter) of the parallel edges of each of the end sections 52, 54 may have a length equal to a quarter of the total length of the assembled duvet or blanket.

[0149] The complete assembled duvet or blanket 16 may have a length which is longer than a standard length for at least one of a King Size, Queen Size, Double or Single duvet in the United Kingdom. This extra length allows for the pocket to be formed in the duvet without shortening the duvet relative to its normal size for a bed.

[0150] In some cases, the complete assembled duvet or blanket 16 may have a length which is longer than a standard length for a Double or Single duvet in the United Kingdom i.e. longer than approximately 200 cm.

[0151] By way of illustration, line 84 in Fig. 6 shows the standard length of e.g. a UK Double duvet as measured from the top edge 62 of the assembled duvet or blanket 16.

[0152] The complete assembled duvet or blanket 16 may have a length for example which is from approximately a sixth to approximately a third longer than the standard length for a single or double duvet in the United Kingdom, i.e. may have a length from approximately 230 cm to approximately 270 cm.

[0153] More preferably, the complete assembled duvet or blanket 16 may have a length for example which is from approximately a fifth to approximately a third longer than the standard length for a single or double duvet in the United Kingdom, i.e. may have a length from approximately 240 cm to approximately 270 cm.

[0154] More preferably still, the complete assembled duvet or blanket 16 may have a length which is from approximately a quarter to approximately a third longer than the standard length for a single or double duvet in the United Kingdom, i.e. may have a length from approximately 250 cm to approximately 270 cm.

[0155] Most preferably, the complete assembled duvet may have a length which is approximately a quarter longer than the standard length for a single or double duvet in the United Kingdom, i.e. may have a length of approximately 250 cm.

[0156] A further aspect of the invention provides a kit of parts comprising: a removable cover for a duvet or blanket in accordance with any of the examples or embodiments outlined above or described below, or as set out in any claim of this application, and a duvet or blanket for receipt within said cover.

[0157] The duvet or blanket has dimensions configured to fit inside the cover, with elongate edges extending coincident with the elongate edges of the cover. The dimensions of the duvet or blanket may be such that the duvet fills at least a portion of the sleeve article which is for receiving the duvet or blanket (e.g. said pouch section in the specific example detailed above). The duvet or blanket may be dimensioned such that end edges of the duvet or blanket extend coincident with end edges of at least a portion of the sleeve article for receiving the duvet or blanket.

[0158] In specific examples, the duvet or blanket may be a duvet or blanket in accordance with any of the particular examples or embodiments outlined above or described below, or set out in any claim of this application.
