[0001] The invention concerns a dispenser for flexible thin elements arranged as a sheet
and separated from one another by tear-off lines, particularly suited to be used with
sheets made up of plastic bags for domestic or similar use.
[0002] The invention also concerns a sheet suited to be housed in the above mentioned dispenser.
[0003] Several types of flexible thin elements arranged as a sheet are known, mainly for
domestic use, like for example plastic bags for food or refuse, which are torn off
one by one and detached from the sheet at the level of the above mentioned tear-off
lines.
[0004] According to a known embodiment, the sheet is packaged in a roll inside a container
or a pack, from which it is withdrawn when it is necessary to tear off the thin elements.
[0005] This embodiment's drawback lies in that it is not very practical, since it is necessary
to handle the sheet in order to find its end and to tear off the thin elements, while
also running the risk of causing it to fall down and be unrolled.
[0006] In addition to that, in the case of thin elements for use with food, the need to
handle the sheet affects the hygiene of the operation.
[0007] Moreover, the lack of practicality described above often leads the user to avoid
putting the sheet back into the container and to leave it exposed to external agents,
thus affecting hygiene even more, especially in the most common case of plastic bags
that, due to electrostatic charges, are more likely to attract dust. According to
the construction variant described above, used mainly in supermarkets to dispense
plastic bags for fruit and vegetables, the sheet is placed in an open container provided
with a shaped edge suited to fit in the opening defined between the handles of each
bag, in order to allow it to be torn off without problems.
[0008] This construction variant does not solve the problem represented by insufficient
hygiene, since the sheet is not protected in any way.
[0009] Furthermore, it still is rather unpractical, since in any case it is necessary to
handle the sheet in order to find its end and to position it correctly before tearing
it off.
[0010] Furthermore, since the sheet is relatively free to move in the container, tearing
off the thin element is not simple and this operation must be performed resolutely,
so much that users often need to use both hands.
[0011] In a further construction variant, the sheet is placed in a container provided with
a slit, from which its edge can be pulled out with no need for the user to handle
the rest of the sheet.
[0012] However, this solution does not eliminate all the drawbacks described above, either,
since the sheet must in any case be kept still with one hand while tearing off the
thin element and the tearing operation thus lacks in practicality and hygiene.
[0013] The present invention aims to overcome all the drawbacks mentioned above, occurring
in the packages of flexible thin elements of known type.
[0014] In particular, it is a first object of the invention to construct a dispenser of
flexible thin elements that allows individual elements to be extracted more easily
compared to known systems.
[0015] It is a further object of the invention to ensure satisfying hygienic conditions
for the thin elements, without making it necessary to touch the sheet in order to
tear off the elements.
[0016] The objects described above have been achieved through the construction of a dispenser
for flexible thin elements arranged as a sheet according to the contents of the main
claim, to which the reader should refer for the sake of brevity.
[0017] The same objects have been achieved also through the use of a sheet constituted by
flexible thin elements suited to be housed in the dispenser mentioned above.
[0018] Other details of the dispenser and of the sheet of the invention are described in
the corresponding dependent claims.
[0019] According to the preferred embodiment of the invention described below, the dispenser
that is the subject of the invention comprises a container for flexible thin elements
as a sheet, separated from one another by tear-off lines arranged across the sheet,
provided with a slit for extracting the sheet and with a projecting body positioned
downstream of the slit according to the direction of extraction and suited to facilitate
the detachment of the thin element from the sheet during extraction of the latter.
[0020] To advantage, since the projecting body stops the sheet while it is being torn off,
tearing itself is simpler and more practical than in the known systems and does not
require the sheet to be held with the hands.
[0021] Furthermore, to advantage, owing to the position of the projecting body, after each
individual element has been torn off, one end of the sheet still projects from the
slit and can thus be easily grasped in order to tear off the successive element.
[0022] Still to advantage, the container protects the sheet from dust and from contact with
the users' hands.
[0023] Furthermore, advantageously, the dispenser that is the subject of the invention can
be fixed to a support surface in an easily accessible position, thus allowing the
user to tear off the thin elements with one hand only, which makes the operation even
more practical.
[0024] Still advantageously, the dispenser can be equipped with a cover that can be opened
to insert a new sheet when the previous one has run out, in such a way as to use the
same container more than once.
[0025] Besides, still advantageously, the dispenser can be produced in a shape suited to
facilitate storage in warehouses or on supermarket counters, or in an ergonomic shape
suited for domestic use.
[0026] A further advantage lies in the possibility to use the same container for sheets
of different size, which can be made by properly shaping the container.
[0027] The above-mentioned objects and advantages will be highlighted in greater detail
in the description that follows, which is provided as an example without limitation,
with reference to the attached drawings, wherein:
- Figure 1 shows an axonometric view of the dispenser that is the subject of the invention;
- Figure 2 shows the sheet contained in the container shown in Figure 1;
- Figure 3 shows an axonometric view of the dispenser of Figure 1 when open;
- Figure 4 shows a cross section of the dispenser of Figure 1 along plane IV-IV;
- Figure 5 shows an enlarged detail of Figure 4;
- Figure 6 shows an axonometric view of the dispenser of Figure 1 during use.
[0028] The dispenser subject of the invention is shown in Figure 1, where it is indicated
as a whole by
1.
[0029] It comprises a container
2 that houses the sheet
3, provided with a slit
6 through which one end
3a of the sheet
3 projects, thus allowing said sheet to be extracted from the container
2.
[0030] As shown in Figure 2, the sheet
3 consists of a plurality of flexible thin elements
4, separated from one another by tear-off lines
5 arranged across the sheet
3 that are preferably constituted by cuts
5a.
[0031] It is arranged in the container
2 preferably rolled up, but in construction variants of the invention it can also be
arranged, for example, in overlapping layers.
[0032] According to the invention, the container
2 comprises a projecting body
7 positioned downstream of the slit
6 according to the direction of extraction
Ve of the sheet
3, suited to be fitted in a through opening
5b made in each thin element
4 to make it easier to detach it from the sheet
3 while this is being extracted.
[0033] Clearly, the projecting body
7 and the through opening
5b may have any shape and size, provided that the former can be housed in the latter
and is also strong enough to hold the sheet
3 during tearing without being deformed.
[0034] Furthermore, the above mentioned through opening
5b is preferably arranged at the level of the tear-off line
5 and appears as a rectilinear cut larger than the cuts
5a.
[0035] As regards the projecting body
7, this is arranged at the centre of the slit
6 in order to advantageously facilitate tearing of the sheet
3.
[0036] Obviously, in construction variants of the invention suited for example to be used
with rather wide sheets
3, the container
2 may comprise several projecting bodies
7, each one of them associated with a corresponding through opening
5b.
[0037] The container
2 defines a longitudinal axis
X along which it maintains a substantially constant cross section with triangular profile.
[0038] It is evident, however, that in construction variants of the invention the container
2 may have a different section, for example cylindrical or rectangular, provided that
it is suitable for containing the sheet
3.
[0039] As regards the slit
6, this is preferably parallel to the above mentioned longitudinal axis
X to facilitate, advantageously, the extraction and tearing of the sheet
3.
[0040] Furthermore, the container
2 is constituted by a base
9 and by a cover
10 mutually connected along part of their edges
9a, 10a via joining means
11.
[0041] Preferably, the projecting body
7 belongs to the cover
10 of the container
2, even if it is clear that in other embodiments of the invention it may belong to the
base
9, or even be a third part connected to the container
2 by suitable joining means like, for example, welds or bonding agents.
[0042] As to the joining means
11, they comprise a thin body
12 carried out in a single piece with the base
9 and the cover
10 and arranged on a rectilinear section of their edges
9a, 10a.
[0043] The thin body
12 advantageously allows the container
2 to be made in one piece only, with consequent savings in production and assembly
times, however it may be replaced by other joining means
11 suited to achieve connection of the cover
10 to the base
9 at the level of the edges
9a, 10a.
[0044] The joining means
11 also comprise a first shaped profile
13 belonging to the base
9 and a second shaped profile
14 belonging to the cover
10 that snap together, for example through undercut surfaces.
[0045] According to construction variants of the invention not illustrated herein, more
than one thin body
12 may be provided and, furthermore, the shaped profiles
13, 14 can be replaced or accompanied by other joining means, like for example adhesive
tape or a layer of bonding agent interposed between the edges
9a, 10a of the base
9 and of the cover
10, which advantageously can work as a sealing agent.
[0046] The slit
6 is defined between the edges
9a, 10a of the base
9 and of the cover
10 along a section of their perimeter without the above mentioned joining means
11.
[0047] Obviously, in construction variants of the invention, the joining means
11 may be arranged on the entire edge
9a, 10a of the base
9 and of the cover
10 rather than just on a part of it, in which case the slit
6 will be created in the body of the base
9 or of the cover
10.
[0048] Advantageously, as can be seen in the section shown in Figure 4 and in the corresponding
detail of Figure 5, the shaped profiles
13, 14 have conjugate sections that are such as to define, at the level of the slit
6, a winding path that limits the penetration of dust into the container
2.
[0049] Furthermore, advantageously, the base
9 is provided with a substantially plane support surface
2a to ensure the stability of the dispenser
1 during use.
[0050] Advantageously, the container
2 is made of a transparent plastic material, so that it is possible to see the quantity
of sheet
3 that is still available inside it.
[0051] It is evident, however, that in construction variants of the invention the container
2 may be made of a material other than plastic, for example cardboard or another sufficiently
strong material.
[0052] Preferably, the container
2 comprises stiffening ribs
8 that are arranged across its longitudinal axis
X and that, advantageously, allow it to be thinner, which consequently reduces its
cost.
[0053] The dispenser
1 of the invention is particularly suited to be used with flexible thin elements
4 consisting of plastic bags for food.
[0054] However, it may also be used with thin elements
4 of any type, provided that they are arranged as a sheet
3, separated by tear-off lines
5 and provided with through holes
5b at the level of each projecting body
7, as described above.
[0055] In practice, as shown in Figure 6, the thin element
4 is extracted by grasping the free end
3a of the sheet
3 and pulling it outwards, following a sliding plane that intersects the projecting
body
7.
[0056] When the through opening
5b of the thin element
4 is at the level of the projecting body
7, the latter is inserted therein owing to the direction of extraction of the sheet
3 described above.
[0057] Therefore, the sheet
3 is held by the projecting body
7 and a further pulling action causes it to be completely torn off along the tear-off
line
5, thus causing the thin element
4 to be detached downstream of the slit
6, that is, at the level of the projecting body
7.
[0058] Figure 6 shows the sheet
3 just before being completely torn off along the tear-off line
5, that is, only partially torn off.
[0059] As explained above and as shown in Figure 1, after tearing the end
3a of the sheet
3 will project from the slit
6 and will thus be able to be grasped when the successive thin element
4 must be torn off.
[0060] It is clear that, in the case of dispensers
1 provided with several projecting bodies
7, the tearing operation will be performed more or less as described above, except for
the fact that the sheet
3 will be held in several points, corresponding to each one of the projecting bodies
7.
[0061] Preferably, if the dispenser
1 is used with food bags, these are arranged in such a way as to have the bottom
4a facing the free end
3a of the sheet
3.
[0062] Advantageously, this ensures maximum hygiene during use, since the free end
3a that projects from the container
2 is closed, thus preventing the penetration of dirt in the bag and any contact of
the hands with the bag on the open side of the latter.
[0063] In the light of the above considerations, the invention achieves all the previously-stated
objects.
[0064] In particular, the presence of the projecting body that fits in the through opening
of each thin element allows the latter to be torn off the sheet in a practical and
safe manner.
[0065] Furthermore, since the container is closed and need not be opened to extract the
thin elements, the object to ensure the optimal hygienic conditions of the thin elements
is also achieved.
[0066] On implementation, the dispenser that is the subject of the invention may undergo
changes that, though not illustrated or described herein, shall nonetheless be covered
by the present patent, provided that they come within the scope of the following claims.
[0067] Where technical features mentioned in any claim are followed by reference signs,
those reference sings have been included for the sole purpose of increasing the intelligibility
of the claims and accordingly such reference signs do not have any limiting effect
on the interpretation of each element identified by way of example by such reference
signs.
