Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a package, and more particularly to a package in which a container with a lid that stores food such as a bento is packaged.

[0002]

[Prior Art]

 In recent years, sushi, various bento boxes, etc. have been sold over the counter, and the demand for them is increasing year by year. Since such bento boxes are often eaten at work or outdoors, they are usually sold with bent chopsticks added. Then, as an additional means, it is directly attached on the container of the lunch box (top surface of the lid) via a rubber band or adhesive tape, or the disposable chopsticks are handed to the purchaser separately from the lunch box packaging. I am.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional one, since the disposable chopsticks are exposed on the outside of the container and the attachment force to the container is weak, the disposable chopsticks are easily separated from the container. Then, the disposable chopsticks that have been removed from the container may fall onto the floor or the ground. In particular, in the case where the bento and the split chopsticks are separated in advance, the problem is more remarkable.

Since the disposable chopsticks are attached to the surface of the container (specifically, the upper surface of the lid) separately from the container, the disposable chopsticks project upward. Then, for example, when a plurality of boxes are purchased together, the lunch box containers in the bag are piled up, but it is difficult to stack them neatly and stably due to the unevenness of the container top surface due to the disposable chopsticks.

The present invention has been made in view of the above background, and an object of the present invention is to provide a packaging body which does not expose the chopsticks to the outside and prevents the chopsticks from being easily separated from the container during transportation. To do.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the packaging body according to the present invention, the side wall surface of the container body containing food such as bento is covered with a heat-shrinkable band-shaped film, and the band-shaped film is heat-shrinked. A film predetermined portion including at least an upper edge is brought into close contact with the peripheral edge of the lid attached to the upper opening of the container body and a predetermined portion of the container body, and the outermost surface of the strip film and the side of the container body. I placed chopsticks between the wall and the wall.

[0007]

[Action]

 In the package according to the present invention, the chopsticks are covered with a band-shaped film to be hygienic, and moreover, the predetermined film portion including the upper edge of the band-shaped film is in close contact with the peripheral edge of the lid and the predetermined part of the container body. Since a closed space is defined between the strip-shaped film and the side wall surface of the container body, the chopsticks do not fall off the container body and fall to the ground or the like during transfer, and the lid body also separates. Is also suppressed at the same time.

【Example】

 Hereinafter, preferred embodiments of a package according to the present invention will be described in detail with reference to the accompanying drawings. 1 to 3 show a first embodiment of the present invention, FIG. 1 is a perspective view of the packaging body 1 of the present invention as seen from the bottom side thereof, FIG. 2 is a plan view, and FIG. 3 is a longitudinal sectional view. Are shown respectively. As shown in the figure, the packaging body 1 of the present embodiment has a flat container body 2 with an upper opening in which a lunch box is housed, and a lid body 3 attached to the upper opening of the container body 2. is doing. The side wall surface 2a of the container body 2 is an inclined surface that widens upward.

Here, in the present invention, first, the heat-shrinkable strip-shaped film 5 is provided so as to surround the front periphery of the side wall surface 2 a of the container body 2. The lower edge 5a of the strip film 5 is bent inward as shown in FIGS. 1 and 3 and is in close contact with the peripheral edge of the bottom 2b of the container body 2. Further, the upper edge 5b of the strip-shaped film 5 is also bent inward as shown in FIGS. 2 and 3 and is tightly attached to the peripheral portion of the lid 3. As a result, the strip-shaped film 5 has a substantially U-shaped vertical cross section, and the container body 2 and the lid body 3 are locked by the upper and lower edges 5b and 5a thereof, and the lid body 3 is prevented from coming off from the container body 2. Has been done. Further, since the central portion of the strip film 5 is also contracted in the vertical and horizontal directions, the locking force is further increased.

Furthermore, in the present invention, as shown in FIGS. 1 and 3, disposable chopsticks 6 are attached to the inner surface of the intermediate portion of the band-shaped film 5. In this example, the disposable chopsticks 6 are in a bag, and the bag and the band-shaped film 5 are bonded and integrated. Specifically, for example, when the material of the bag is paper, it is performed via a pressure sensitive adhesive, and when the bag is made of film material such as vinyl, it is integrated by any means such as pressure sensitive or heat sensitive. Can be achieved.

In this embodiment having such a configuration, since the film material does not exist at the position facing the central portion of the lid body 3 and the lid body 3 is exposed to the outside, for example, the lid body 3 is transparent. When it is made of a plastic film, the contents can be seen easily, and the contents of the stored bento can be easily seen.

Further, in this example, since the disposable chopsticks 6 are mounted along the side wall surface 2a of the container body 2, only the flat lid 3 is provided on the upper surface of the packaging body 1 so that a plurality of packaging bodies 1 can be easily formed. It can also be stacked. Moreover, since the side wall surface 2a is inclined, the attached disposable chopsticks 6 do not project outward from the side edge of the lid 3.

Next, an example of a method of manufacturing the packaging body 1 will be described. First, the annular band-shaped film 5 to which the disposable chopsticks 6 are attached is arranged so as to surround the container body 2. At this time, the upper and lower edges 5b and 5a of the strip film 5 are positioned so as to project from the upper surface and the lower surface of the container body 2, respectively. In addition, in order to make the strip film 5 into a ring, it is possible to use a film that is originally in a ring, but in order to perform high-speed processing such as automatic packaging processing, two strip films are used. This is preferably done by heat sealing the ends together.

Next, in this state, the strip-shaped film 5 is heated through a heating device such as a shrink tunnel. Then, the band-shaped film 5 is thermally shrunk and contracted in the vertical and horizontal directions, and accordingly, the upper and lower end portions 5b and 5a are bent inward, and as shown in FIGS. 1 to 3, the lid body 3 and the container body 2 are It adheres to the bottom 2b. As described above, in this example, there is a manufacturing merit that the packaging work for the container (the container body 2 with the lid body 3 attached) and the installation work for the disposable chopsticks 6 can be performed simultaneously by a series of operations.

FIG. 4 shows a second embodiment of the present invention and is a view corresponding to FIG. 3 showing the first embodiment. In the present embodiment, unlike the above-described first embodiment, the band-shaped film 9 to which the disposable chopsticks 8 are attached has a two-layer structure, and the disposable chopsticks 8 are wrapped with the band-shaped film 9. With this structure, it is not necessary to bond the disposable chopsticks to the strip-shaped film as in the first embodiment.

As a result, there is no problem in hygiene even if bare chopsticks without a bag or the like are used. In this example, the use of the disposable chopsticks in the bag is not obstructed, and the bag and the band-shaped film may be adhered.

Further, in this example, as shown in the drawing, the strip-shaped film 10 on the side where the disposable chopsticks 8 are not provided is formed of a single film as in the first embodiment, and the cost is reduced.

Next, a method of manufacturing the package of this embodiment will be described. The basic method is the same as that of the first embodiment, and only the characteristic points will be described. First, the strip-shaped film 9 to which the disposable chopsticks 8 are attached is formed by bending a relatively wide strip-shaped film from its center into a substantially V (U) shape, and loading the disposable chopsticks 8 therein. Such a band-shaped film 9 containing the disposable chopsticks 8 and one narrow band-shaped film 10 are bonded together at their front and rear end portions to form a ring shape. The other steps are the same as in the first embodiment described above.

Preferably, after the disposable chopsticks 8 are loaded on the V-shaped strip film 9, a predetermined position of the strip-shaped film 9 (for example, the upper side or the front and rear end sides of the disposable chopsticks 8) is line-sealed or point-sealed. It is to be. As a result, the strip-shaped film 9 is arranged around the container body 2, or the split chopsticks 8 pop out of the strip-shaped film 9 when the strip-shaped films 9 and 10 are finally cut to open the lid 3. Alternatively, it can be more reliably prevented from moving inside.

FIG. 5A shows a vertical cross-sectional view of a side surface portion of a package according to a third embodiment of the present invention. As shown in the figure, in this embodiment, the upper edge of the heat-shrinkable band-shaped film 12 is closely attached so as to surround the engaging portion 11 between the container body and the lid. That is, only the upper edge side of the strip-shaped film 12 is in close contact with the upper peripheral edge of the container body and the peripheral edge of the lid body, thereby suppressing the detachment of the lid body. As a result, as shown in the figure, the lower edge of the band-shaped film 12 does not adhere to the bottom of the container body, and this state can be configured such that it covers the entire circumference of the bottom, although not shown. In order to prevent the lid from coming off more reliably, it is of course possible to use a configuration in which a part or all of the lower edge of the strip-shaped film 12 is in close contact with the bottom peripheral edge of the container body.

FIG. 2B shows a modification of the third embodiment. As shown in the figure, in the case of using a container in which a ridge 13a projecting upward is formed on the peripheral edge of the lid body 13, the uppermost edge 14a of the strip film 14 is the same. The ridge 13a is wrapped around the upper surface of the ridge 13a so as to cover and adhere it. With such a configuration, the lid 13 can be more reliably prevented from coming off.

In each of the above-mentioned embodiments, an example in which disposable chopsticks are used as the chopsticks to be loaded in the packaging position 1 has been described, but the present invention is not limited to this, and any chopsticks can be used. Of course. Moreover, the close contact between the strip film 5 and the bottom portion 2b of the container body 2 and the lid body 3 does not necessarily have to be performed over the entire circumference, and there may be a partial close contact or even a portion that is not in contact. The point is that the lid body 3 should be in close contact with the lid body 3 so that the lid body 3 does not easily come off.

[0023]

[Effect of the device]

 As described above, in the package according to the present invention, since the band-shaped film covers the chopsticks, it is hygienic, and the predetermined part of the band-shaped film is in close contact with the periphery of the lid and the predetermined part of the container body. Since a closed space is defined between the strip-shaped film and the side wall surface of the lidded container, the chopsticks will not be detached from the lidded container and fall to the ground or the like during transfer.

Further, as described above, since the strip-shaped film is in close contact with the lid body and the container body, the locking force of the lid body with respect to the container body is increased, and the lid body is prevented from coming off. it can.
