Abstract

 Devices for grouped support and transport of receptacles and cardboard sheets to form them. The devices of the invention are executed in cardboard or pasteboard and comprise a smooth surface (12) which covers the top of the receptacles, which protects the caps from dirt, allows printing and consequent reading of a bar code for the whole set, provides enough stiffness to the formed support, increased in some of the forms of execution. They also comprise one or more lower (14) surfaces for retention of receptacles provided with retention openings formed by radial flanges (17) of special shapes. The devices are preferably made of cardboard or pasteboard diecast sheets which are introduced over the top of the receptacles and which by simple bending and adhesion form the devices. The invention has application in the support and transport of receptacles in groups of one or more rows, especially soft drink cans or pots.

Description

[0001] The invention refers to devices for the grouped support and transport of receptacles, as well as the cardboard or pasteboard sheets to form and execute said devices.

[0002] The invention is destined to overcome the drawbacks or inconvenients that the devices hitherto known present for the transport of groups of receptacles, especially the receptacles of cylindrical or slightly frustoconical shaped top provided in their caps with a rim or shoulder, a specific example of application being the currently known soft drink cans or pots.

[0003] In accordance with the state of the art, this type of supporting devices are formed from bands or strips in cardboard or plastic, in which openings are executed provided with flanges or radial projections for retention of the receptacles to be supported, which remain with their upper base or cap exposed to the outside, as for example the article carrier described in U.S. patent 3,432,202. Another well known form of execution is that composed of a plurality of flexible plastic rings which surround the top of the receptacles making several ways of grouping possible. Such devices thus present two main deficiencies or inconveniences. One of a hygienic nature, since the spilling or direct ingestion of the contents of the receptacles becomes more frequent every day, and it is not desirable that the dirt resulting from being exposed during storage and transport accumulate in their tops or caps. Another drawback is of an economic or commercial nature, in particular in relation to the use, more extended every day, of the sales charging and control system called bar code, reading of which is not possible with the supporting devices presently known, especially when the receptacles are arranged in adjacent rows, unless it is done separately and with great difficulty in handling for each one of the receptacles, but never for the whole supported set.

[0004] Another inconvenient of the known devices lies in their general lack of stiffness for a comfortable and uniform handling and transport of the set of receptacles supported, unless they are very ligth. For example, they are not adequate for the typical cans or pots of soft drinks, in which a group of three units already attains a weight of about one kilogram. This limitation has been solved, for example, by means of basket devices, which involve an increased cost of the device and difficulties in its mechanical filling and execution, or else by means of the presence of additional areas of adhesive which give cohesion to the whole, which means the presence of a more or less persistent or undesirable substance in the receptacle, in particular in the area of the caps. Also use of materials of greater stiffness has been resorted to, specifically plastics, giving rise to devices in which the receptacle are difficult to extract and, above all, generate ecologically unacceptable residues.

[0005] An additional drawback lies in the difficulty for the known devices being provided with handles or holding means for transport, without thereby substantially complicating their structure or the amount of material utilized.

[0006] Therefore, it is one objective of this invention to provide devices for grouped support and transport of receptacles, which smoothly cover the upper part of such receptacles; which have enough stiffness to support a variable number of such receptacles, even though they be relatively heavy; which make possible to read the bar code for a set of receptacles; which are executed in an ecologically acceptable material; that the receptacles be easy to extract; and that without affecting the previous purposes, have a simple execution, including being provided with holding means, which allows said execution and the incorporation of the receptacles by mechanical means.

[0007] The devices of the invention fulfill that objective and others which will be mentioned later, when executed in cardboard or pasteboard and when they comprise a smooth surface which covers the top of the receptacles, which protects their caps from dirt, allows the printing and subsequent reading of a bar code for the whole set, provides enough stiffness to the support formed, increased in some forms of execution. All of this from diecast sheets which are introduced over the top of the receptacles and which by simple bending and adhesion form the support and transport devices for the receptacles.

[0008] Other objectives and results of the invention are to provide support and transport devices for a group of receptacles, in which without altering their essential structure holding means are provided, as well as means to avoid possible oscillation or rocking of the receptacles supported, so that noises from their bumping are reduced, greater comfort is provided in handling and stacking the devices, and the risk of accidental detachment of any receptacle supported by the devices is reduced.

[0009] In a basic form of execution, a device for grouped support and transport of receptacles according to the invention:
- is made of cardboard or pasteboard, and comprises two surfaces,
- a lower one for retention of receptacles, in which there have been determined, by opposite alternation between two lines of marking and two lines of cut, series of two or more retention openings for the receptacles, axially aligned, and
- an upper surface for covering the caps of the receptacles, which is smooth and of a substantially rectangular shape in plant,
- the contour of said retention openings being circular, with a diameter coinciding with or slightly longer than the one of the caps of the receptacles to be supported by
- retention flanges projecting from each of the marking lines in the shape of a circular segment with concavely arched chord.

[0010] In another form of execution, a device according to the invention:
- is made of cardboard or pasteboard, and comprises
- two lower surfaces for retention of receptacles arranged in adjacent manner, in each one of which it has been determined, by opposite alternation between two lines of marking and two lines of cut, a series of two or more retention openings for receptacles, axially aligned, and
- an upper surface covering the caps of the receptacles, which is smooth and of substantially rectangular form in plant,
- from which a handle part extends,
- the contour of said retention openings being circular, with a diameter coinciding with or slightly longer than the one of the caps of the receptacles to be supported by
- retention flanges projecting from each of the lines of marking in the shape of a circular segment with concavely arched chord.

[0011] In a preferable form of execution, the zone of union or transition between lines of marking and lines of cut in the retention openings presents an empty space or cut of approximately semicircular shape open toward the inside of said retention openings.

[0012] Also, in a preferable form of execution, the marking lines comprise spaced cuts which follow their same arched contour.

[0013] In another form of execution, a device according to the invention:
- is made of cardboard or pasteboard, and comprises
- a lower surface for retention of receptacles in which, by diecasting and marking, two rows of two or more equal retention openings for receptacles have been determined, each row being in axial alignment and separated from one another by a smooth zone provided with holding means,
- each one of these retention openings having a shape approximately equivalent to three quarters of a circle, of a diameter equal to or slightly longer than the one of the caps of the receptacles,
- first flanges for retention of receptacles projecting radially in variable number from the inner circular margin of said retention openings, which are placed in a position diametrically opposite the smooth zone which separate the rows of retention openings, and
- second unitary flanges for retention of receptacles at each side of the first ones, which extend to join with the said smooth zone, and which adopt a shape approximately of a circular segment of concave chord,
- U-shaped cuts being provided in the separation between the first and second retention flanges, and
- an upper surface covering the caps of the receptacles, which is smooth and substantially rectangular in plant and which has in its central zone holding means coinciding in position and dimension with those of the smooth zone of the lower surface for retention of receptacles.

[0014] In a further form of execution, a device according to the invention:
- is made of cardboard or pasteboard, and comprises
- a lower surface for retention of receptacles in which by diecasting and marking, two rows of two or more equal retention openings for receptacles have been determined, each row being in axial alignment and with its retention openings in tangential contact with the openings of the other row,
- the spaces between the retention openings of one row and the other being occupied by holding means,
- being said retention openings of a circular shape, of a diameter equal to or slightly longer than the one of the caps of the receptacles,
- first flanges for retention of receptacles projecting radially in variable number toward the inside of said retention openings, located in a position diametrically opposite to other group of flanges substantially equal,
- second unitary flanges for retention of receptacles, located between the groups of first ones, which adopt a shape approximately of a circular segment of concave chord,
- U-shaped cuts being provided in the separation between the first and second retention flanges, and
- an upper surface covering the caps of the receptacles, which is smooth and substantially rectangular in plant and which has in its central zone holding means coinciding in position and dimension with those of the lower surface for retention of receptacles.

[0015] In another form of execution, a device according to the invention:
- is made of cardboard or pasteboard, and comprises
- a lower surface for retention of receptacles in which, by diecasting and marking, two rows of two or more equal retention openings for receptacles have been determined, each row being in axial alignment and with its retention openigs in tangential contact with the retention openings in the other row,
- holding means occupying the spaces between the retention openings of the two rows,
- each one of said retention openings having a circular shape, of a diameter equal or slightly longer than the one of the caps of the receptacles,
- first flanges for retention of receptacles projecting radially in variable number toward the inside of said retention openings, which are placed in a position diametrically opposite to other group of substantially equal flanges,
- second unitary flanges for retention of receptacles, located between the groups of first retention flanges, which adopt a shape approximately of a circular segment of concave chord,
- U-shaped cuts being provided in the separation between the first and the second retention flanges,
- being the retention openings occluded by flaps which extend from the group of first retention flanges placed in a position adjacent to the other row of retention openings toward the inside of said retention openings,
- said flaps being adhered through the inside of the device to
- an upper surface for covering the caps of the receptacles, which is smooth and substantially rectangular in plant, and which has in its central zone holding means coinciding in position and dimension with those of the lower surface for retention of receptacles.

[0016] In a preferable form of execution, the holding means are two or more aligned openings, of a diameter longer than that of the finger of an adult.

[0017] In a preferable form of execution, the retention openings of each row are in tangential contact.

[0018] In a preferable form of execution, the tangential contact zone between retention openings comprises a cut portion which enables later lifting of the retention flanges affected by that zone.

[0019] In a preferable form of execution, the retention openings of each row are in tangential contact and the corresponding zones of contact present a hole or aperture.

[0020] In an optional form of execution, the device has lines for tearing or pulling out transverse to the alignment of the receptacles, which allow splitting the device into portions which support or transport a number of receptacles desired by the consumer.

[0021] In any of the foregoing executions, the devices of the invention are manufactured from cardboard or pasteboard sheets, also being an objective of the invention, in which the retention and covering surfaces show the characteristics and configurations previously defined and which are joined by means of the corresponding flaps or parts which, by folding or bending and subsequent gluing or stapling, produce formation of the devices of the invention.

[0023] In Figure 1 an example is illustrated of a diecast sheet of cardboard of pasteboard for executing a support and transport device for receptacles according to the invention. Said sheet adopts a substantially rectangular shape, on which by lines of marking or folding (10,11) two surfaces or end flaps (12,13) have been constituted, being also substantially rectangular and of a different width (although they could be equal), and by superposition, as illustrated in Figure 2, and union by means of adhesive or other means, constitute the upper surface (20) of the supporting device as illustrated in Figures 3 and 4.

[0024] The central surface (14) of the sheet shows a series of equal retention openings (three in the example), axially aligned, of circular contour and in tangential contact, each one constituted by the regular or diametrically opposite alternation between lines of marking (15) and lines of cut (16), which together compose the cited circular contour. From the lines of marking (15) a pair of retention flanges (17) for each receptacle project, approximately in the form of a circular segment of chord (18) arched concavely.

[0025] Preferably, each one of the points or zones of transition or separation between lines of marking (15) and lines of cut (16) have a small space or cut approximately semicircular (19) which purpose will be explained later.

[0026] As illustrated in Figure 2, the sheet is superposed on receptacles (30) by their surface (14) provided with retention openings.

[0027] The receptacles (30) may be of a large variety of types, but those having a frustoconical shape or a shoulder in their top forming with their rim a perimetral notch or groove will be preferred. An example are the cans illustrated in Figure 2, although other receptacles may be suitable, including those in which their upper parts form the said perimetral notch or groove in the proximity of their caps.

[0028] The diameter of the cap of the receptacles (30) should coincide with or be slightly less than the one of the contour of the retention openings of the surface (14) of the sheet, which when it is superimposed and pushed toward the base of the receptacles until the edge or chord (18) of the flanges (17), snaps into the cited perimetral notch or groove of the cap of the receptacles (30). Then the flaps (12,13) are folded and joined, as indicated previously, and the support device of the invention is formed with its upper smooth surface (20) and lower surface of retention (14) as represented in Figures 3 and 4.

[0029] In these figures, and as can be understood it is also illustrated that a device according to the invention might support groups of two or more receptacles (30) depending on the number of retention openings with which it is equipped. Thus, in Figure 5 a device supporting four receptacles (30) is illustrated which could also be splitted into groups of two receptacles, by the lines of tearing or pulling out (100) previously marked in a direction transverse to the alignment of the receptacles (30) and which pass between the retention openings.

[0030] By the preceding description, it is deduced that the union between the supporting device and receptacles (30) depends on the flexion or ease of lifting of the flanges (17) along the lines of marking (15). Furthermore, it can be understood and observed in Figures 3, 4 and 5, that the lower surface (14) of the device suffers a concave-convex deformation as soon as the flanges (17) snap in the perimetral groove of the receptacles (30), which ease of deformation also depends on the hinge of said flanges (17) on the marking lines (15).

[0031] In order to increase said lifting or flexion of the flanges (17), in the example of sheet illustrated in Figure 1, the lines of marking (15) present spaced cuts (21) in a coinciding arched contour, for example in the positions illustrated in the example. These cuts, in the margins of the surface (14) of the sheet, are replaced by small cuts (22).

[0032] In Figures 6 and the ones following it, other examples of forms of execution of the device of the invention are represented, as well as examples of diecast sheets for shaping such devices. In these figures the same numeral references as heretofore are employed to designate the parts or pieces coinciding, and in the description that follows specific mention will only be made of the variations introduced with respect to what has been described and illustrated with reference to Figures 1 to 5.

[0033] Thus, in Figure 6 a similar sheet to that of Figure 1 is represented, except that it comprises a flap (23) in continuation of the (12), the purpose of which, as can be seen in Figure 7, is to provide an additional surface or panel in contact with the side of the receptacles (30), capable of containing information on the content of said receptacles, and also to add transverse stiffness to the device. It is understood that the dimension of the surface or panel which the flap (23) provides may vary from case to case, as well as the possible presence of adhesive between the inside face of the panel (23) and the lateral one of the receptacles (30), so that a greater security of retention by the support device is achieved also. Likewise, this device can be provided with tearing or pulling out lines (100) mentioned in relation to Figure 5.

[0034] In Figure 8 an example of diecast sheet is represented which permits a support and transport device like the one illustrated in Figure 9, which is different from the previous ones in being provided with an upper handle (24). As represented in Figure 8, the surface (14) provided with retention openings is extended on one end by means of a rectangular flap (25) and on the other end by means of a first rectangular flap (26) of width aproximately equal to half of that corresponding to the surface (14) and by two equal flaps (27,28) provided one with an opening (29) and the other with a cut (31) with which it partially coincides in shape.

[0035] In order to form the device illustrated in Figure 9 from the diecast sheet of Figure 8, the flap (25) is folded onto the surface (14), of course after the introduction of the caps of the receptacles (30), and then onto said flap (25) the flap (26) is folded with interposition of adhesive, so that the device is basically formed, finally constituting the handle (24) by joining flaps (27,28), opening (29) and cut (31) coinciding to form a window (32) for introduction of the user's fingers. It is understood that the width of the flaps (27,28) depends on the height desired for the handle (24), and also, as represented in the example, the flaps (27,28) can have a slightly trapezoidal shape.

[0036] In Figure 10 an example of sheet similar to the one in Figure 8 is represented, except that it is extended on one of its ends by a first flap (33) of equal dimensions to the (26) and by a second flap (34) of variable dimensions. The result is the device illustrated in Figure 11, provided with a panel (34) which performs the same task mentioned in the description of the sheet and device of Figures 6 and 7.

[0037] As aforementioned, the supporting devices according to the invention may support two or more receptacles (30). However, according to the weight of said receptacles (30), after three or four units the upper and lower surfaces (20,14) of the device may experience some deformation during handling by the user.

[0038] For such cases of heavy receptacles or for a relatively high number of receptacles to be supported, it will be preferable to utilize another devices according to the invention, examples of which and of the sheets capable of forming them are illustrated in Figures 12 to 44.

[0039] In Figure 12 a sheet which substantially coincides with the example of basic execution illustrated in Figure 1 is represented, the difference lies in the fact that at each side of the central surface (14), equipped with retention openings for retention of receptacles, and before the end flaps (35,36), by means of spaced pairs of folding lines (37,38) and (39,40) two narrow rigidizing flaps (41,42) are constituted which when folded to form the device according to Figures 13 to 16 constitute ribs through the lines (37,38,39,40) which work as rigidizing or resistance agents to the strains which the devices experience when holded. As represented in Figure 16, this execution of the device may also be equipped with tearing or pulling out lines (100).

[0040] In Figure 17, an example of sheet similar to the one in Figure 12 is represented, except that it comprises a flap (43) in continuation of the (35), constituting a panel (43) for the device illustrated in Figure 18, which scope has previously been explained.

[0041] In Figure 19 an example of diecast sheet from which is derived the device illustrated in Figure 20 is represented, which is different from the previous ones in which an upper handle (44) is provided. As its is represented in said Figure 19, one of the narrow rigidizing flaps (41,42) in the example the (41), is joined or it is extended by means of a first rectangular flap (45) of width approximately equal to half that corresponding to the surface (14) provided with retention openings, and by two flaps (46,47) equal in width, provided one with an opening (48) and the other with a cut (49) partially coinciding in shape with said opening. The way of folding and retention is the same as the one explained for the example in Figure 8, and the result is the device which is illustrated in Figure 20.

[0042] In Figure 21 an example of a sheet similar to the one in Figure 10 is represented, except that it is extended at one of its ends into a first flap (50) of equal dimensions as the (45), and a second flap (51) of variable dimensions. The result is the device illustrated in Figure 22, provided with a panel (51) which performs the same functions enunciated in the description of the sheets and devices in Figures 6, 7, 10, 11, 17 and 18.

[0043] In Figure 23 it is illustrated an example of a diecast sheet, of cardboard or pasteboard, to execute a support and transport device for receptacles according to the invention, especially designed to support receptacles (30) in two parallel rows.

[0044] As represented, the sheet adopts a substantially rectangular plant, in which two surfaces or flaps (60,61) have been constituted by lines of marking or folding (55,56,57,58,59) provided with retention openings (62), between which two flaps (63,64) are located making configuration of a handle attached to the whole set. By joining and superposition, as illustrated in Figure 24, and union by means of adhesive or other means, the formation of the upper surface (20) and a handle (65) for the supporting device in two rows is achieved, as illustrated in Figures 25 and 26.

[0045] The surfaces or flaps (60,61) of the sheet each have a series of equal retention openings (62) (three in the example), axially aligned, of circular contour and in tangential contact, each one constituted, as explained previously, by the regular or diametrically opposite alternation between lines of marking (15) and lines of cut (16) which together compose the said circular contour.

[0046] From the lines of marking (15) retention flanges (17) project, of a form approximating a circular segment of chord (18) arched concavely. Also according to what was previously mentioned, each one of the points or zones of union or transition between lines of marking (15) and lines of cut (16) will preferably present a small space or cut (19) approximately semicircular the scope of which is to improve the adaptation of the retention openings (62) at the cap of the receptacles, in particular with the rim which they used to be provided.

[0047] The central flaps (63,64) of the sheet show centered windows or openings (66,67) having a form, position and dimension coinciding, destined to constitute, in due time, together with the said flaps (63,64) the handle (65) of the device.

[0048] As illustrated in Figure 24, the sheet is superimposed on parallel rows of receptacles (30) by their flaps (60,61), provided with retention openings (62). As in the examples of execution previously described, the diameter of the caps of the receptacles (30) coincides or is slightly less thanthe one of the contour of the retention openings (62) in the flaps (60,61) of the sheet, which once superimposed is pressed toward the base of the receptacles (30) as far as the edge or chord (18) of the flanges (17) is introduced by snapping into the perimetral notch or groove of the top of the receptacles (30). Then the flaps (63,64) are folded by the line (55) until they remain back to back, and thus side by side the two rows of receptacles (30) in the retention openings (62). Finally, the flaps (68,69) at the end of the sheet are folded onto the cap of the receptacles (30). One of those flaps, in the example the (69), show an appendix or projection (70) of form, position and dimension coincident with the openings (66,67) of the flaps (63,64), through which passes in the previous folding, coming to be located in contact over the flap (68) receiving in that zone an adhesive or other means of retention. Thus the support device is formed, with its upper smooth surface (20), a perpendicular handle (65) and lower adjacent surfaces of retention (60,61) as represented in Figures 25 and 26, in which, as can be understood, the possibility is also illustrated that the device grouped rows of two or more receptacles (30) depending on the number of retention openings (62) with which it is provided.

[0049] Also, as in the previous examples of execution, to increase the hinge or flexion of the flanges (17) in the retention openings (62), the lines of marking (15) present spaced and in a coinciding arched contour some cuts (21), for example in the positions illustrated in Figure 23. Such cuts (21) in the margins of the flaps (60,61) of the sheet, are replaced by small cuts (22).

[0050] In this form of execution, the devices according to the invention support two rows of two or more receptacles (30) each. However, as was previously explained, for heavy receptacles or for a relatively high number of receptacles to be supported, the use of devices and sheets as in the examples illustrated in Figures 27 to 29, is preferable.

[0051] In Figure 27 an example of sheet is represented which coincides substantially with the example of execution illustrated in Figure 23. The difference lies in the fact that between flaps (60,68) and (61,69) by spaced pairs of lines of folding (37,38) and (39,40), two narrow rigidizing flaps (41,42) are formed, which on being folded to form the device according to Figures 28 and 29 constitute ribs by the lines (37,38,39,40) which work as rigidizing agents resistant to the strains which the devices experience on being holded.

[0052] By the preceding description it is deduced that one of the principal characteristics of the devices according to the invention lies in the configuration of its retention openings for receptacles, on the basis of the pair of retention flanges (17) opposite each other.

[0053] Despite obtaining satisfactory results with such flanges, in Figure 30 an alternative execution is represented for the retention openings, applicable to all the examples described previously. In this form of execution, the retention openings are formed by a circular marking line (52) of a diameter coinciding or slightly longer than the one of the caps of the receptacles (30) and from that marking line, besides the flanges (17) already described, other smaller flanges (53) project radially separated by lines of cut (54), the inside of the retention opening being empty. The result will be a retention opening (62) with flanges (17,53) which will completely surround the cap of the receptacle and will be introduced by snapping their edges in the notch or groove of each cap.

[0054] In Figure 31, a further example of sheet is illustrated, for executing a device also for two rows of receptacles in a more simplified form than the one described in the preceding paragraphs. In this example the sheet also adopts an approximately rectangular plant, in which by lines of marking or folding (71,72,73,74,75,76) two surfaces or zones (77,78), among others, have been constituted provided with rows of retention openings (62), between which is located a flap (79) provided with an opening (80) which will constitute part of a holding means for the whole set. On each side of the surfaces (77,78) other flaps (81,82) and (83,84) extend, the task of which will be explained later, although here it must be indicated that the surfaces (77,78) constitute together the lower surface for retention of receptacles of the device, and the flap (84) the upper surface for protection of the caps of the receptacles, according to the characteristics of the invention previously mentioned.

[0055] In this form of execution, the retention openings (62) adopt a form approximately equivalent to three quarters of a circle interrupted in its contact with the marking lines (73,74) which delimit the flap or central zone (79) which separates the surfaces (77,78). The diameter of these retention openings (62) is understood to be equal or slightly longer than the one corresponding to the cap of the receptacles (30) to be supported.

[0056] From the inner circular margin of the retention openings (62) first retention flanges (85) project radially, three in the example represented, but which might be in any other number. Said first retention flanges (85) are located in a position diametrically opposite to the central flap (79). Second unitary retention flanges (86), two in each retention opening (62), are located at each side of the first retention flanges (85) and adopt a form approximately of a circular segment of concave chord, which is extended by its narrowest end until union or contact with the said central flap (79). The first retention flanges (85) are separated by straight radial cuts (87), while the separation between the group of first retention flanges (85) and second retention flanges (86) is constituted by larger U-shaped cuts (88) destined to facilitate the deformation of flanges (85,86) at the moment of introduction over the cap of the receptacles of the retention openings (62).

[0057] In Figures 32 and 33 equivalent sheets to the one represented in Figure 31 are illustrated, except that they are respectively adapted to support six or eight receptacles in two rows. In view of the consequent greater weight to support by the devices which the said sheets would make, a larger number of holding means has been provided. Thus, while in Figure 31 the holding means will be constituted by coincidence of opening (80) in flap (79) with opening (89) in flap (84), when the latter is brought down over the first one, in Figure 32 the openings to constitute holding means are double and in Figure 33 triple. In these figures the same numeral references have been employed for designating the same parts or elements.

[0058] In Figure 34 a phase of the execution of a device according to the invention is represented, with two rows of three receptacles (30). As can be observed, the sheet is introduced over the properly grouped receptacles until their caps penetrate into the retention openings (62) and the retention flanges (85,86) snapped into the lower part of the rim (90) which these receptacles generally have in their cap. The foregoing operation is even facilitated in the case of cans or pots of soft drinks which in the proximity of said rim (90) show a narrowing determining a shoulder. Then the flap (81) is folded or brought down over the cap of the receptacles (30) and the flap (84) over that one, in both cases acting as hinges the narrow flaps (83,84), respectively. The application of adhesive in appropriate zones of the flaps (81), (79) and (84) constitutes the formation of the device which is represented already completed in the example of Figure 35.

[0059] The material utilized, cardboard or pasteboard, generally has enough flexibility to allow the displacement of the retention flanges (85,86) during their introduction into the cap of the receptacles (30). However, said displacement can be facilitated by means of cuts (91) made on the marking lines which constitute the retention flanges, for example in the positions illustrated in Figures 31, 32 and 33.

[0060] In Figures 36 to 41 another form of execution of a device and of the sheets which constitute said device is represented. This form of execution basically coincides with the one which was just described in relation to Figures 31 to 35, so that the same numeral references are maintained and repetition of the characteristics which have already been described is avoided.

[0061] The principal difference in relation to the form of execution previously described lies in the retention openings (62), which show a complete circular contour and a second group of retention flanges (92) approximately equal to the (85) and which are located diametrically opposite to them. From said retention flanges (92) flaps (93) extend, which partially occupy the inner surface of the retention openings (62), destined to impede oscillation or rocking of the receptacles (30).

[0062] It is also observed that in this form of execution the retention openings (62) corresponding to each row are in tangential contact, and that the holding means openings (80) occupy the spaces between said openings (62). This execution with openings in tangential contact is considered preferable, but should be understood that nothing would prevent the existence of an intermediate flap similar to the one designated with the reference number (79) in Figures 31 to 34.

[0063] In Figure 39 a phase of the formation of a device from the sheet of Figure 37 is illustrated, here giving as stated what was said in relation to Figure 34. Also, it will be observed in Figure 40, where the device is represented already formed, that at least externally it has an aspect similar to the one represented in Figure 35.

[0064] As indicated previously, the flaps (93) have a scope of preventing or making less likely the oscillation or rocking of the receptacles (30) supported, especially toward the outside of the device, and the way in which the flaps (93) fulfill this task will be understood from the detail illustrated in Figure 41.

[0065] In that figure it can be observed that flanges (92) instead of being snapped in the rim (90) of the receptacles (30), as it happens with retention flanges (85,86), surround that rim and the flaps (93) which extend from them are adhered to the lower face of the flap (84) by means of one or more adhesive layers (94). In this way, displacement or oscillation in approximation of receptacles (30) is prevented due to their proximity or contact, while the displacement or oscillation in separation of receptacles (30) is prevented or made significantly less likely by the stopping effect which the flanges (92) make against the rims (90).

[0066] It is understood from the previous description that the flaps (93) may totally or partially occupy the inner surface of the retention openings (62) and adopt an equal or different form inside said retention openings (62).

[0067] In Figure 42 an alternative execution is represented for the retention openings (62), applicable to all the examples described previously. This form of execution is basically similar to the one described in connection with Figure 30. So retention openings (62) have a circular shape constituted by a marking line (52) from which retention flanges (17,53) project. What constitutes the difference is the fact that the tangential contact zones between retention openings in their respective row, present a hole or aperture (101) with a shape approximately to an ellipse, in order to ease the bending or lifting of the retention flanges (17) when snapping in the rim (90) of the receptacles (30).

[0068] In Figure 43 it is illustrated a sheet incorporating the form of execution of the retention openings (62) shown in Figure 42. As can be observed this sheet is similar to the one represented in Figure 38 and also comprises the holding means (80,89) provided there, and even this form of execution could be completed with the flaps (93).

[0069] Finally, Figure 44 is an enlarged view similar to Figure 40, showing how the hollow tangential zones of contact (101) enable the snapping of the retention flanges (17) under the rims (90) of the receptacles (30).

[0070] In all the forms of execution described, the characteristic is present of providing a smooth surface which covers the cap of the receptacles, as well as also smooth lateral surfaces in some of the executions, these surfaces being easily utilizable for printing information on the product in the receptacles, including the so-called bar code. Likewise, in all the forms of execution described a highly resistant support and transport device is provided, even for a relatively high number of receptacles in these executions, whether or not holding means are provided. Also, in all the forms of execution described the folding of the cardboard sheets which form the devices and the incorporation to them of the receptacles is very simple, so that it becomes very easy to assign these operations to a machine.
