  In stores such as fast food stores, it is required to quickly deal with many types of orders from customers. However, from the viewpoint of ease of inventory management and cost, there are not many types of food packaging containers 1 prepared in stores, and many different types of hamburgers are used for the box-shaped food packaging containers 1 of the same form. And other ingredients. In actual packaging, usually, a plurality of food packaging containers 1 having the same shape are arranged side by side, and different types of hamburgers are assembled in the containers.

  On the other hand, the inner surface of the food packaging container 1 for packaging hamburgers and the like is plain with no pattern on both the lower container part 2 and the upper container part 3, and the store clerk only looks at the food packaging container 1 from the top. Cannot be identified. Of course, the outer surface of the container differs depending on the type of hamburger and can be identified, but it takes time for the store clerk to visually recognize the outer surface. Therefore, the store clerk puts the ingredients in which container after placing the lower bread a and the upper bread b, which are common members, in the lower container part 2 and the upper container part 3 of each food packaging container 1. It is necessary to make a note or remember it, which is a big burden for the store clerk. In some cases, the contents to be assembled may be wrong, and a hamburger with contents different from the order may be delivered to the customer.

  By applying an identification pattern on the inner surface of the food packaging container 1 by printing or the like, the clerk can proceed with the work while visually checking which kind of hamburger should be made in which container. it can. However, it is not a preferable solution from the viewpoint of food hygiene only by printing the printing ink directly on the inner surface of the container in contact with food to form a pattern.

  For this reason, it has become a major issue to be solved in the industry to prevent mistakes in the contents of hamburgers and the like that should be assembled in each container while processing quickly.

  The present invention answers the above-mentioned problems, and even if it is a food packaging container of the same form, it can be easily identified as to which application it should be used by simply looking at it from above, and contains it. An object of the present invention is to provide a food packaging container that does not adversely affect the food to be produced, and a food packaging sheet material for producing the food packaging container.

  The food packaging sheet material according to the present invention is a food packaging sheet material comprising a laminate of an outer surface sheet, a core sheet and an inner surface sheet, and a pattern is formed on the side facing the inner surface sheet of the core sheet. And the pattern can be identified through the inner surface sheet.

  The inner sheet forms a surface for containing (touching) the food when the food is packaged, and the outer sheet is generally given an aesthetic design. The pattern is a line, a character, a figure, a symbol, or a combination thereof, or a combination of these and a color, and is not limited. Therefore, it may be a character pattern, a picture pattern, a line pattern or the like, or a combination pattern thereof. It is good also as a pattern by making colors different. In any case, a printed pattern is desirable from the viewpoint of mass productivity and cost.

  In the food packaging sheet material according to the present invention, the core sheet may be a flat sheet, but is preferably a corrugated paper material. In either case, unbleached paper is preferable. Furthermore, in the sheet material for food packaging according to the present invention, the basis weight of the core sheet is preferably the same as the basis weight of the inner sheet or larger than the basis weight of the inner sheet.

  The food packaging container according to the present invention is a food packaging container made by boxing the above-mentioned food packaging sheet material, wherein the inner surface sheet is boxed as a side in contact with food, and the core The pattern formed on the sheet is visible from the outside through the inner surface sheet.

  In one specific aspect of the food packaging container, the food packaging container has a box-shaped lower container portion and a box-shaped upper container portion that selectively take an open posture and a closed posture via a hinge portion. It is characterized by being able to obtain.

  The food packaging container made by boxing the food packaging sheet material according to the present invention can make the pattern formed on the side facing the inner surface sheet of the core sheet visible from the outside through the inner surface sheet. Therefore, for example, a container user such as a store clerk can easily differentiate each container using the pattern as a clue even when the user looks at the plurality of food packaging containers from above.

  For this purpose, for example, the store clerk can quickly use food at the store by making known the usage manual such that the pattern A container is for a-form food and the pattern B container is for b-form food. Even in the case of packaging, it is possible to effectively avoid the occurrence of a situation in which the contents of food to be put in each container are mistaken.

  Moreover, the said pattern is not the inner surface sheet which is a surface which food contacts, but is formed in the side which faces the inner surface sheet of a center sheet | seat, and a foodstuff is not harmed by a pattern.

  When the sheet material for food packaging is a paper material having a corrugated shape, a pattern is preferably applied to the flat paper material before imparting the corrugated shape, which is shaped into the corrugated shape. As a result, a clear pattern can be formed and the contact area between the core sheet and the inner surface sheet can be reduced, and it is possible to more reliably prevent the pattern from seeping out on the surface of the inner surface sheet. can do.

  Depending on the selection of each sheet, the pattern formed on the side facing the inner surface sheet of the core sheet may pass through the outer surface sheet and be seen from the outside of the container. This affects the design of the outside of the container. In order to avoid this, it is desirable that the core sheet is made of unexposed paper. By using unbleached paper, the concealing effect of the pattern on the original printed surface, that is, the design on the outside of the container is enhanced.

Moreover, the basic weight of a core sheet should just be equal to or more than the basic weight of an inner surface sheet. The basis weight of the inner surface sheet is preferably ^{30g / m 2 ~150g / m 2} . Within this range, the pattern formed on the core sheet can be seen (identified). Moreover, if the basic weight of a core sheet is larger than 30 g / m < ² >, the said shielding effect will become easy to be acquired.

  In the food packaging container according to the present invention using the sheet material for food packaging according to the present invention, by forming a pattern on the core sheet, each food packaging container having the same form can be viewed from above by simply looking at it from above. Containers can be easily differentiated. Therefore, even when the store clerk wraps food quickly at the store, it is possible to effectively avoid the occurrence of a situation in which the contents of the food to be put in each container are mistaken. Further, the pattern is formed on the core sheet, and does not adversely affect the food to be contained.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  First, an example of a food packaging sheet material will be described. The food packaging sheet material 10 is composed of a laminate of an outer surface sheet 11, a core sheet 13, and an inner surface sheet 12. In the food packaging sheet material 10, an identification pattern is formed on one surface of the core sheet 13, and the surface on which the identification pattern is formed is covered with the inner surface sheet 12. The other surface of the core sheet 13 is covered with the outer surface sheet 11.

  The outer surface sheet 11 and the inner surface sheet 12 are not limited, but are preferably a paper material or a laminate of a paper material and a resin film such as a polyethylene film. By sticking the resin film on one surface of the paper material, it is possible to prevent moisture, moisture and oil from oozing out to the outside of the container. However, the inner surface sheet 12 needs to be a material that can be seen through the inner surface sheet 12 through the opposite side. The core sheet 13 is desirably a paper material having a corrugated shape because it is lightweight and has a required strength. When a corrugated paper material is used as the core sheet 13, a food packaging sheet material 10 having a corrugated cardboard structure is obtained.

  FIG. 1 shows an example of a manufacturing process for producing a food packaging sheet material 10 having a cardboard structure. First, as shown in FIG. 1 (a), an appropriate pattern is formed on one surface of a flat sheet material 13a by means such as printing. In the example shown in FIG. 1, two line patterns 14, 14 are formed by printing. Although not shown in the figure, it may be a pattern such as a character or a pictograph, or may be an appropriate pattern in which a color is changed to give an identification. In any case, it is preferable that the paper material is unbleached paper because a so-called concealing effect that makes it difficult to see the printed pattern from the opposite side is exhibited.

  The paper material 13a after printing is subjected to waveform processing to obtain a paper material 13b having a waveform shape as shown in FIG. Next, as shown in FIG.1 (c), the inner surface sheet | seat 12 is affixed on the side in which the said pattern 14 of the paper material 13b was formed, for example using a starch paste. Further, on the opposite side of the paper material 13b, a highly designable outer surface sheet 11 having a product name or brand name printed on the surface is attached. When the outer surface sheet 11 or the inner surface sheet 12 is a sheet in which a resin film such as a polyethylene film is bonded to one side of the paper in advance, the resin film side may be applied to the core sheet 13 and bonded by heat fusion. it can.

  FIG. 2 shows a cross section of the food packaging sheet material 10 thus prepared. As described above, the inner surface sheet 12 is a material through which the opposite side can be seen through. When viewed from the direction of the arrow in FIG. 2, the viewer can place the pattern 14 on the inner surface sheet 12. Without being obstructed, the inner surface sheet 12 can be seen through from the outside.

  When the food packaging container 1 as described with reference to FIG. 5 is prepared using the food packaging sheet material 10, first, as shown in FIG. The mount 1a is die-cut from the sheet material 10. In FIG. 3, for convenience of explanation, different types of line patterns 14 a to 14 e are printed on the core sheet 13 of the food packaging sheet material 10. However, the same pattern 14 may be repeatedly formed on one food packaging sheet material 10.

  In FIG. 3, two patterns 14a are a set of line patterns, and are formed on portions corresponding to the left and right side walls of the mount 1a. The pattern 14b is a set of two line patterns, and is formed only at one place in the center of the mount 1a. The pattern 14c is a single thick line pattern, and is also formed only at one location in the center of the mount 1a. The pattern 14d is a set of two line patterns made up of thin lines compared to the pattern 14b, and is formed only at one central portion of the mount 1a. The pattern 14e is a single thick line pattern, and is formed in a portion corresponding to the left and right side walls of the mount 1a.

  An example of the food packaging container 1 assembled using such a mount 1a is shown in FIG. The overall shape of the food packaging container 1 is the same as that of the food packaging container 1 described with reference to FIG. 5, and the lower container part 2 and the upper container part 3 are connected via a hinge part 4. The example shown in FIG. 4 is an example in which the pattern 14e shown in FIG. 3 is assembled using a mount 1a formed on portions corresponding to the left and right side walls of the mount 1a.

  In this food packaging container 1, the above-described pattern 14 e formed on the core sheet 13 is not obstructed by the inner surface sheet 12 on the left and right side walls 5, 5, etc., as shown in the figure. Can be seen from the outside. And although not shown in figure, by using the sheet material 10 for food packaging shown in FIG. 3, although the whole shape is the same, five types of food which can visually recognize different patterns 14a-14e seeing from the top A packaging container 1 is formed.

  Therefore, as described above, the pattern 14a container is for the a-form food, the pattern 14b container is for the b-form food, the pattern 14c container is for the c-form food, and the pattern 14d container. For example, in a fast food store, etc. by making the used manual that associates the type of pattern and the type of food known, such as for food in d form, and for containers in pattern 14e. When providing food such as hamburgers, even if the store clerk packs food quickly at the store, it is easy to avoid the situation that the type of food to be put in each container 1 is wrong. It becomes possible to do.

  Further, the patterns 14a to 14e are not formed on the inner surface sheet 12 which is a surface in contact with food in the food packaging container 1, but are formed on the side facing the inner surface sheet 12 of the core sheet 13. The food is not harmed by the patterns 14a to 14e.

  Depending on the selection of each sheet, the patterns 14a to 14e may pass through the outer surface sheet 11 and be seen from the outside of the container 1, but the core sheet 13 may be made of unexposed paper, or This can be avoided by improving the concealing effect of the core sheet 13 by making the basis weight of the core sheet 13 larger than the basis weight when no such pattern is applied.

Specifically, if the basis weight of the core sheet 13 is 50 g / m ² , the strength is sufficient. Moreover, it is preferable that the basic weight of the core sheet 13 is the same as or more than the basic weight of the inner surface sheet. Here, the basis weight of the inner surface sheet ^30g / ^{m 2 ~150g} / m 2 is desirable. If it is this range, the pattern formed in the core sheet from the inner surface sheet surface can be seen (recognized). Therefore, the basis weight of the core sheet 13 is preferably 30 g / m ² or more, and more preferably 50 g / m ² or more. Thereby, while satisfy | filling required intensity | strength, it can prevent that a sleeper sees from an outer surface.

  In the above-described patterns 14a to 14e, it may be preferable to form the pattern on a portion corresponding to the left and right side walls of the mount 1a, rather than forming it on the center of the mount 1a. The reason is that when the pattern is in the center of the container, the pattern may be blocked by the food depending on the size of the food to be stored. Since this tends to occur when the pattern is an independent pattern such as a character or a picture pattern, special attention is required.
