Description

The present invention relates to a food packaging body made of a plastic film for packaging triangular food such as cooking bread and confectionery bread.

For example, Patent Document 1 and Patent Document 2 describe sandwich packaging materials made of plastic film as triangular food packages such as cooking breads and confectionery breads. Such a food package is formed as a bag by connecting two generally isosceles trapezoidal plastic sheets having a substantially isosceles trapezoidal food container. An upper knob portion is formed on the food storage portion having a substantially isosceles trapezoidal shape.

In the sandwich packaging body of Patent Document 1, a printing unit is provided by printing directly on the surface of a packaging body body made of a transparent gas-impermeable plastic film (Claims 1, 1 and 2). ).

In the sandwich packaging material of Patent Document 2, both ends of the two outer films are sealed, and the two outer films are sealed so as to form a seal line connected to both ends of the outer film. Easy peel properties are imparted to a range corresponding to both ends of the cut in the seal region where the line is formed. In order to impart this easy peel property, an intermediate film interposed between two outer films is provided, and the two outer films are indirectly sealed by being sealed to the intermediate film so as to form a seal line. (Paragraph 0046). As a result, the “second region” above the bag portion has a stiffness (0031 paragraph, 0050 paragraph, etc.). Also in the invention of Patent Document 2, information such as a name and an image relating to a product is given by printing directly on the outer film (paragraphs 0014 and 0050).

Japanese Utility Model Publication No. 6-61779 JP 2009-184702 A

Conventional food packaging bodies such as sandwich packaging materials described in Patent Literature 1 and Patent Literature 2 are directly printed on a plastic sheet constituting the main body portion, thereby giving information such as names and images about products. Therefore, when it is desired to make different indications for a plurality of foods, food packages corresponding to the number of types of foods must be prepared. However, in a cooking pan such as a sandwich, many kinds of products are often made by a sandwiching tool even if they have the same external shape. In addition, the type of product may continue to change due to the use of seasonal ingredients. However, many people who manufacture and sell cooking pans have small businesses, and it is a great burden to hold and use many types of food packages. It is also difficult to recreate the entire food packaging for each new product.

In the sandwich packaging materials described in Patent Document 1 and Patent Document 2, printing is performed to display a food name or the like on a knob portion provided on a bag portion that stores food. The print provided in this part does not hide the cut end of the sandwich and is conspicuous so it is easy for consumers to see. However, since the conventional sandwich packaging material such as Patent Document 1 is made by superimposing two plastic sheets, this knob portion is thin and hardly stands in a clean state. Of course, if a thick plastic sheet is used, the knob portion can also have a firmness, but the amount of material used is increased and the cost is increased accordingly. In addition, with a thick plastic sheet, it is difficult to fold the mouth after putting food. If an intermediate sheet is inserted as in Patent Document 2, only the knob portion can have a firmness, but the structure of the packaging material becomes complicated, and if the three sheets are accurately stacked and bonded, the manufacturing process Is also complicated.

An object of the present invention is to provide a label sheet for a food packaging body and a food packaging body that can easily package triangular foods, and can freely display product descriptions and the like with a simple structure at low cost.

In order to solve the above problems, a label sheet for a food packaging body according to the present invention is formed on an upper knob portion of a food packaging body formed by superposing two plastic sheets having a food container having a substantially isosceles trapezoidal shape. It is a label sheet for food packaging to be attached by thermal welding, has the shape of the upper knob part provided on the upper part of the food container of the food packaging body, and one surface is attached to the upper knob part by thermal welding. The other surface is a printing surface.

The food packaging body of the present invention is a food packaging body formed by superposing two plastic sheets, each of the two plastic sheets being a substantially isosceles trapezoidal food containing portion and an upper portion thereof. A food packaging having a knob part, a connecting part for connecting two plastic sheets by heat welding between the food container part and the upper knob part, and having a printing surface on the outer surface of the upper knob part A body label sheet is attached by heat welding. Furthermore, it is preferable that an intermediate sheet is provided in the food container between the two plastic sheets, and the upper end portion of the intermediate sheet is connected to the two plastic sheets by thermal welding at the connection portion.

The label sheet for a food packaging body according to the present invention is a simple one composed of a connection surface and a printing surface for being attached to the upper knob portion of the food packaging body by heat welding, and is attached to the upper knob portion of the food packaging body. By attaching, it is possible to easily display a description of the product on the food package. It is only about the same size as the upper knob, can be manufactured at low cost, and does not require a storage location. By sticking to the upper knob part, it is possible to give a firmness to that part and to effectively show the display of the printed surface to the consumer.

It is a top view which shows a front side plastic sheet. It is a top view which shows a back side plastic sheet. It is an enlarged longitudinal cross-sectional view which shows a food packaging body. It is a perspective view which shows the use condition of a food packaging body.

EMBODIMENT OF THE INVENTION The form for implementing this invention is demonstrated in detail based on drawing. FIG. 1 is a plan view showing a food packaging label and a food packaging main body. FIG. 2 is a perspective view showing food.

The food package body 1 includes a first plastic sheet 2 and a second plastic sheet 3 that are substantially the same shape. The first plastic sheet 2 and the second plastic sheet 3 each include an isosceles trapezoidal food container 4. This food container 4 is a main part for packaging food, and corresponds to the shape of the food x to be packaged. Of the two parallel upper and lower sides, the shorter side is the upper side 6 and the longer side is the lower side 7.

Here, the food packaged by the food package 1 will be described. The food x has a triangular prism shape with a right triangle as the bottom. As a typical example of the food x, the present invention can be applied to cooking bread such as sandwiches, sweet bread such as steamed bread, and confectionery. FIG. 2 shows a state in which food is erected with the shortest side x1 of the right-angled triangle facing down. At this time, the smallest angle x4 of the right triangle is on the upper side.

The angle θ between the hypotenuse 5 of the isosceles trapezoid and the vertical line 8 on the upper side is about half of the angle θx of the smallest angle x4 of the right triangle of the food x. Further, the length w of the upper side 6 of the isosceles trapezoidal part is approximately the same as or slightly longer than the thickness wx of the food x. Further, the height h of the isosceles trapezoidal portion is longer than the length hx of the hypotenuse x3 of the right triangle of the food x.

A connecting portion 9 between the first plastic sheet 2 and the second plastic sheet 3 is formed on the hypotenuse 5 of the isosceles trapezoidal food container 4. Further, a connecting portion 10 is also formed on the upper side portion 6. The lower side portion 7 is an opening where the first plastic sheet 2 and the second plastic sheet 3 are not connected.

3 is a plan view showing the front side plastic sheet, and FIG. 4 is a plan view showing the back side plastic sheet. The front side plastic sheet and the back side plastic sheet are almost the same shape as a whole. These correspond to the first plastic sheet 2 and the second plastic sheet 3 in FIG. The front side plastic sheet 2 and the back side plastic sheet 3 have an upper knob part 11 on the food container 4. In this example, the upper knob portion 11 is also an isosceles trapezoid, and its hypotenuse is an extension of the hypotenuse of the food container 4. However, the upper knob portion 11 may be rectangular.

The food package described above has already been used as a package for sandwiches. Below, the label sheet for food packaging bodies is demonstrated. The food packaging label sheet 20 is practically the same shape as the upper knob 11 of the food packaging, or slightly smaller than that. In the example of FIG. 1, since the upper knob part 11 is an isosceles trapezoid, the label sheet 20 for food packaging bodies is also the same shape as it.

The food packaging label sheet 20 is made of a transparent or translucent plastic sheet, but one surface is a printed surface. For example, it is possible to print a display relating to food, such as a display of a product name, a manufacturer or a seller, or a photograph or an illustration using a raw material as a motif.

The opposite side of the printing surface is a connection surface for affixing by heat welding in accordance with the front side surface of the upper knob portion, that is, the outer surface of the front side plastic sheet 2. For example, if the raw material of the food packaging label sheet 20 is a heat-weldable film, the opposite side of the printed surface becomes the connection surface as it is. Alternatively, the connecting surface may be formed by applying a hot-melt adhesive called hot melt that does not have adhesiveness at room temperature and exhibits adhesiveness when heated to some extent as an adhesive.

If this label sheet 20 for food packaging bodies is attached to the upper knob part 11 of the food packaging body main body 1 by thermocompression bonding, a food packaging body having a printing surface is formed. Here, the label sheet 20 for food packaging body may be attached at any point in the period during which the food packaging body is manufactured and used. You may attach at the time of manufacturing the 1st plastic sheet 2. FIG. Once the food packaging body 1 is manufactured, the food packaging label sheet 20 may then be attached and supplied to a food processor or food distributor.

Furthermore, the food packaging body main body 1 and the food packaging label sheet 20 are supplied separately, and the food processor or food distributor attaches the food packaging label sheet 20 before packaging the food. Is also possible. In this case, if the food processor or the food distributor has the food packaging label sheet 20 corresponding to the number of types of food provided by the food processor or food distributor, the food processor or the food seller can handle all types of food. For example, in the case of a sandwich, a plurality of products having different ingredients are often provided. However, even if the ingredients are different, the outer shape of the triangular sandwich is almost the same, so that it can be packaged with the same food packaging body 1. By selecting the food packaging label sheet 20, packaging suitable for each type of triangular sandwich can be achieved. Further, even when a new product is developed and the previous product is abolished, only the food packaging label sheet 20 needs to be new, and the already-owned food packaging body 1 can be used as it is.

In the food package body 1 of the example shown in FIG. 1, an intermediate sheet 12 is provided in the food container 4 between the first plastic sheet 2 and the second plastic sheet 3, and the upper end of the intermediate sheet 12 is The connecting portion 10 is connected to two plastic sheets by heat welding. FIG. 5 is a longitudinal sectional view showing the food package. This intermediate sheet 12 enters between the triangular food cut and the back surface of the first plastic sheet 2 so that the food cut does not directly touch the first plastic sheet 2. Since the intermediate sheet 12 only covers the cut end of the food, it need not be thick.

A packaging method using this food package will be described. FIG. 6 is a perspective view showing a use state of the food package. Open the mouth of the food package 1 and put the food x inside. At this time, the food x is inserted from the smallest corner x4. Further, the oblique side x3 of the food x is directed to the front plastic sheet 1, and the intermediate sheet 12 is placed between the back surface of the first plastic sheet 2 and the surface (cut) of the oblique side x3 of the food x. Therefore, the cut end of the food x hits the intermediate sheet 12 and does not touch the first plastic sheet 2 directly. At this time, the long vertical side x2 hits the back side plastic sheet. When the apex x4 of the food x reaches the upper side 6 of the food package 1, the isosceles trapezoidal portion 4 of the food package opens along the outer shape of the food x and becomes substantially the same shape.

Next, fold the mouth with caramel. And an adhesive seal etc. are affixed on a folding part, and a folding part is stopped. Thus, the triangular food x is packaged in the food package. The packaged food x is placed on the food shelf with the first plastic sheet 2 facing forward. At this time, the upper knob part 11 has the food packaging body on the upper side, and the printing surface 21 of the label sheet 20 for food packaging body attached to the upper knob portion 11 faces the front. Therefore, the display prepared by the food provider is effectively shown to the consumers. Also, the store clerk can grasp at a glance what the product on the shelf is. The upper knob 11 is composed of three sheet members obtained by adding the label sheet 20 for food packaging to the first plastic sheet 2 and the second plastic sheet 3 and has sufficient thickness and rigidity, so that it is cleanly upright. To do. Therefore, the consumer can display the printing surface 21 more beautifully and clearly to the consumer.
