Description

  The present invention relates to a wrapping film.

  Groceries such as candy and candy are sold in plastic containers. At this time, the food product is wrapped by a transparent film together with the plastic container. Specifically, the food product is covered with the wrapping film, and both ends of the wrapping film are attached to the side wall of the plastic container. This prevents the food product from spilling out of the plastic container. Conventionally, the wrapping film is firmly attached to the plastic container so that the wrapping film is not detached from the plastic container.

JP 2010-111422 A

  However, if the wrapping film is firmly attached to the plastic container, it becomes difficult for the food purchaser to remove the wrapping film from the plastic container when taking out the food from the plastic container. Although it is possible to remove the wrapping film from the plastic container by pulling the wrapping film with a large force, there is a risk that the food will fall out of the plastic container due to the reaction when the wrapping film comes off the plastic container. .

  If the wrapping film is broken using tools such as scissors and a cutter knife without removing the wrapping film, the food can be taken out from the plastic container without dropping the food. However, there is a risk of damaging food by the tool and the troublesomeness of using the tool.

  Therefore, a wrapping film has been proposed that is difficult to tear under normal use, but can be broken without using tools when taking out food. For example, Patent Document 1 discloses a wrapping film to which a tear tape is attached. According to this wrapping film, by pulling the tear tape, the wrapping film is torn along the tear tape, thereby breaking the wrapping film. However, the wrapping film disclosed in Patent Document 1 requires a step of attaching a tear tape to a predetermined position of the wrapping film in the manufacturing process. For this reason, manufacture is complicated and it is difficult to reduce manufacturing cost.

  Therefore, an object of the present invention is to provide a wrapping film that is easy to manufacture and can be broken without using tools such as scissors and a cutter knife.

The wrapping film according to the present invention includes a film-like wrapping portion having a first end edge constituting a free end portion and a second end edge constituting a free end portion on the opposite side, and a first end of the wrapping portion. A pair of incisions formed at positions at or near both ends of the region where the tongue piece is formed in the first end edge of the wrapping portion; Correspondingly, a notch formed in the second end edge is provided. Further, the wrapping portion and the tongue piece are integrally formed of a film base material. Two or more sets of the tongue piece and the notch corresponding to each other are provided in the wrapping portion, and the plurality of notches provided in the second end edge are separated from each other, and the wrapping portion is separated from the wrapping portion. It is possible to break from the second end edge side through a single sheet portion between a plurality of notches, the first end edge and the third end edge adjacent to the second end edge, and the first The wrapping film has a fourth edge adjacent to the one edge and the second edge and located on the opposite side of the third edge, and covering the upper surface of the container with the upper surface open. The third edge and the fourth edge are affixed to the container .

First, the configuration of the present invention will be specifically described.
A wrapping film according to the present invention includes a film-like wrapping portion having a first edge and a second edge opposite to the first edge, a tongue piece formed on the first edge of the wrapping portion, and a first wrapping portion. It is provided with a pair of cuts formed respectively at positions at both ends of the region where the tongue piece is formed on the edge or in the vicinity thereof. Further, the wrapping portion and the tongue piece are integrally formed of a film base material. As the material of the film base material, various materials that can be a film base material and can be broken, such as resin, paper, and cloth, are used.

  According to the wrapping film, by pulling the tongue piece toward the second end edge of the wrapping portion, the wrapping portion is torn from the leading ends of the pair of cuts. As a result, a part of the wrapping part is torn together with the tongue piece in a strip shape, and the wrapping film is torn. Thus, the wrapping film has a configuration that can be easily broken by the presence of the tongue piece and the pair of cuts. Further, since the tongue piece protrudes from the first end edge, the presence of the tongue piece allows the viewer to recognize the position where tearing starts.

  In the wrapping film, the pair of cuts preferably extend obliquely from the first edge so as to be separated from each other.

  When the tongue piece is pulled, the width of the band-shaped portion that is torn off together with the tongue piece tends to gradually decrease from the tongue piece side, and therefore the band-shaped portion is located at a position between the first edge and the second edge. Easy to break. On the other hand, according to the wrapping film, the distance between the ends of the pair of cuts is increased. Therefore, even if the strip-like portion is interrupted at a position between the first end edge and the second end edge, the length thereof is increased. Therefore, when the wrapping film is broken, the wrapping target can be easily taken out from the broken portion.

  In the wrapping film, it is preferable that the side edges and the pair of cuts of the tongue piece extend so that the side edges and the cuts corresponding thereto are aligned. Such a wrapping film is produced by cutting a film substrate with a cutting blade. Specifically, the cutting blade has a cutting edge extending in a straight line, and the cutting edge forms a side edge and a cut of the tongue piece aligned in a straight line. Therefore, the shape of the cutting blade is simple.

  In the specific configuration of the wrapping film, a notch is formed on the second end edge of the wrapping portion corresponding to the tongue piece. In this configuration, the shape of the edge of the notch and the shape of the edge of the tongue piece are preferably substantially the same.

  The above specific configuration is suitable for producing a plurality of wrapping films by cutting a film substrate. Specifically, when the film substrate is cut, the first end of the wrapping portion of one wrapping film and the second end of the wrapping portion of another wrapping film are formed by one cutting to form a tongue piece. Edges and notches can be formed simultaneously. Therefore, the production of the wrapping film can be made efficient.

  In a specific configuration of the wrapping film, the wrapping portion is provided with two sets of tongue pieces and notches corresponding to each other, and the two notches provided at the second end edge are separated from each other. In this configuration, the edge of each notch is preferably V-shaped.

  According to the specific configuration, by pulling the portion between the two notches from the second end edge side of the wrapping portion toward the first end edge, the wrapping portion is torn from the two notches as the starting point. . As a result, a part of the wrapping part is torn off in a strip shape, and the wrapping film is torn. Further, as described above, the wrapping film can be broken also by pulling the tongue piece from the first end edge side of the wrapping portion. That is, the wrapping film can be broken from both sides. Therefore, even if the wrapping film is broken only from one side, even if the wrapping object cannot be removed from the broken part, the wrapping film can be reliably removed by breaking the wrapping film from the other side. become. Furthermore, since the two notches are recessed at the second edge, the presence of these notches allows the viewer to recognize that there is a position between the two notches that begins to break.

Next, embodiments of the present invention will be specifically described with reference to the drawings.
<First Embodiment>
FIG. 1 is a plan view showing a wrapping film 100 according to the first embodiment of the present invention. FIG. 2 is an enlarged view showing a main part of the wrapping film 100. The wrapping film 100 is formed by cutting a film substrate into a predetermined shape. As the material for the film substrate, resins such as polyvinyl chloride, polyvinylidene chloride, polystyrene, polypropylene, polyethylene, polyethylene terephthalate and the like are used. The material of the film base material is not limited to this, and various materials that can be a film base material and can be broken, such as paper and cloth, can be used.

  As shown in FIG. 1, the wrapping film 100 includes a wrapping portion 1, a tongue piece 2, a pair of cuts 3, and a notch 4. The wrapping unit 1 is a part that covers a wrapping target in a normal use state of the wrapping film 100 (see FIG. 3). Therefore, the wrapping portion 1 occupies most of the wrapping film 100. In the present embodiment, the shape of the wrapping portion 1 is rectangular, and therefore the wrapping portion 1 has four end edges that extend straight. The shape of the wrapping portion 1 is not limited to a rectangle, and various shapes such as a shape with rounded corners of the rectangle can be adopted.

  The tongue piece 2 is formed on the first end edge 1a of the wrapping portion 1 and protrudes from the first end edge 1a. The tongue piece 2 has a size that can be picked up with a finger. As described above, the wrapping film 100 is formed by cutting the film substrate into a predetermined shape. Therefore, the tongue piece 2 is formed integrally with the wrapping portion 1. In the present embodiment, the tongue piece 2 has a rectangular shape, and thus the tongue piece 2 has two side edges 2a extending substantially perpendicular to the first end edge 1a. In addition, the shape of the tongue piece 2 is not limited to a rectangle, and various shapes such as a trapezoid and a triangle to be described later can be adopted.

  As shown in FIG. 2, the pair of cuts 3 are respectively formed at positions P1 on both ends of the region R1 where the tongue piece 2 is formed on the first edge 1a. In this embodiment, each notch 3 is formed on the extended line of the side edge 2a of the tongue piece 2 corresponding to this. Therefore, the two side edges 2a and the pair of cuts 3 of the tongue piece 2 extend so that the side edges 2a and the corresponding cuts 3 are aligned.

  As shown in FIG. 1, the notch 4 is formed at the second end edge 1 b opposite to the first end edge 1 a of the wrapping portion 1. Specifically, a notch 4 is formed in a region R2 of the second end edge 1b facing the region R1 where the tongue piece 2 is formed at the first end edge 1a. The shape of the edge of the notch 4 is substantially the same as the shape of the edge of the tongue piece 2.

  FIG. 3 is a perspective view showing an example of use of the wrapping film 100. As shown in FIG. 3, the wrapping film 100 is used for wrapping food items (not shown) such as candy and candy contained in a plastic container 101.

In the scene where the wrapping object is taken out, as shown in FIG. 4, the tongue piece 2 is pulled from the first edge 1a side of the wrapping portion 1 to the second edge 1b (the white arrow shown in FIG. 4). . As a result, the wrapping portion 1 is torn starting from the tips 31 of the pair of cuts 3. As a result, a part of the wrapping portion 1 is torn together with the tongue piece 2 in a band shape, and thereby the wrapping film 100 is torn. Thus, the wrapping film 100 has a configuration that can be easily broken by the presence of the tongue piece 2 and the pair of cuts 3. Further, since the tongue piece 2 protrudes from the first end edge 1a, the presence of the tongue piece 2 makes it possible for the viewer to recognize the position where breakage starts.

  FIG. 5 is a plan view used for explaining the manufacturing method of the wrapping film 100. As shown in FIG. 5, first, a long film substrate 10 is prepared. Then, the film substrate 10 is cut at a predetermined interval by a cutting blade (not shown). Here, the cutting blade has a shape capable of cutting the film substrate 10 along the cutting line 10a shown in FIG. Specifically, the cutting blade has a shape capable of forming the first edge 1 a, the tongue piece 2, and the pair of cuts 3 by cutting the film substrate 10. And the area | region r between the two cutting lines 10a adjacent in the longitudinal direction of the film base material 10 is an area | region used as the wrapping film 100. FIG.

  According to such a manufacturing method, by cutting the film substrate 10, the two regions r having the cutting line 10a as a boundary are divided. As a result, a first end edge 1a, a tongue piece 2, and a pair of cuts 3 are formed in one region r. At the same time, the other region r has an end edge that is generated as a result of the formation of the first end edge 1 a and a recess that is generated as a result of the formation of the tongue piece 2. And this edge and a hollow become the 2nd edge 1b and the notch 4, respectively.

  Accordingly, the second end of the wrapping portion 1 of another wrapping film 100 can be cut once to form the first edge 1a of the wrapping portion 1 of one wrapping film 100, the tongue piece 2, and the pair of cuts 3. The edge 1b and the notch 4 can be formed simultaneously. Therefore, according to the said manufacturing method, manufacture of the wrapping film 100 can be made efficient. In this way, the configuration of the wrapping film 100 in which the shape of the edge of the notch 4 and the shape of the edge of the tongue piece 2 are substantially the same is used when a plurality of wrapping films 100 are formed by cutting the film substrate 10. Is suitable.

  Further, in the present embodiment, the cutting blade has a cutting edge extending in a straight line, and the cutting edge forms a side edge 2a and a cut 3 of the tongue piece 2 aligned in a straight line. Therefore, the shape of the cutting blade is simple.

As shown in FIGS. 6A and 6B, in the wrapping film 100, the pair of cuts 3 preferably extend obliquely from the first edge 1a so as to move away from each other. Further, from the viewpoint of simplifying the shape of the cutting blade, the two side edges 2a of the tongue piece 2 extend obliquely so that each side edge 2a and the corresponding notch 3 are aligned. It is preferable. Accordingly, the shape of the tongue piece 2 may be a trapezoid as shown in FIG. 6 (a) or a triangle as shown in FIG. 6 (b). Furthermore, it is preferable that the shape of the edge of the notch 4 is substantially the same as the shape of the edge of the tongue piece 2 (not shown) from the viewpoint of improving the production efficiency of the wrapping film 100.

  As shown in FIG. 4, when the tongue piece 2 is pulled in the scene where the wrapping target is taken out, the width of the band-like portion torn off together with the tongue piece 2 tends to gradually decrease from the tongue piece 2 side. Therefore, the strip-shaped portion is likely to be interrupted at a position between the first edge 1a and the second edge 1b. On the other hand, according to the wrapping film 100 according to the first modified example (FIGS. 6A and 6B), the distance L between the tips 31 of the pair of cuts 3 is the wrapping film 100 shown in FIG. Greater than its distance L. Therefore, even if the belt-like portion is interrupted at a position between the first end edge 1a and the second end edge 1b, the length thereof is increased. Therefore, when the wrapping film 100 is broken, the wrapping target (for example, food) can be easily taken out from the broken portion.

  FIG. 7 is an enlarged view of a main part of a second modification of the wrapping film 100 according to the first embodiment. As shown in FIG. 7, in the wrapping film 100, each cut 3 may be formed at a position P2 different from the position P1 in the first edge 1a. According to this structure, the distance L between the front-end | tips 31 of a pair of cut 3 can be enlarged similarly to the said 1st modification. In addition, it is preferable that the position P2 where each incision 3 is formed is in the vicinity of the position P1 so that only the tongue piece 2 is not broken when the tongue piece 2 is pulled.
