Description

  The present invention relates to a paper container for food packaging, and the container is constituted by a laminated material in which a thin paper having water resistance is coated on a blank material made of cardboard having a relatively hard feeling so as to be peeled off. , Fried noodles, okonomiyaki, takoyaki, frankfurt, etc.

  Paper containers used for packaging food, ekiben, etc. in various events such as festivals are used with their inner surfaces made water resistant by coating the surface of cardboard with resin or aluminum foil, for example. When food is stored in such a paper container, liquid seasonings applied to the food may contaminate aluminum foil, etc., but are blocked by this and penetrate into the paper quality part of the container. No appearance and clean packaging is maintained. However, since the aluminum foil part is contaminated, it is necessary to peel off the contaminated aluminum or to wash away liquid seasonings to recycle the paper part of the container. It is possible or difficult, and many are incinerated, leading to waste of resources.

Thereafter, a paper container having a paper container made of cardboard as a main body and a thin paper film bonded to the inner surface has been used. In this container, since only the film on the inner surface side is contaminated by seasonings, etc., if the film is peeled off from the container and separated and collected from the main body side cardboard, at least the cardboard side will not be contaminated, so as a paper resource Can be recycled.

However, after eating and drinking a lunch box in a double-layer paper container made of cardboard and thin paper at an event, etc., the user peels off the cover film contaminated with seasonings etc. from the container body and separates and discards each. There was almost no.

Therefore, as a motivational measure for peeling the thin paper from the thick paper of the two-layer paper container, in the container consisting of a laminated blank in which a substrate paper blank and a dirt prevention cover film are laminated, a folding adhesive portion for three-dimensional formation I devised a lottery information printed on a specific concealed part. In this container with lottery information, a person who eats and drinks disassembles the container after eating, peels off the cover film, confirms the lottery information, and acquires profits according to the information. Expected to peel off the film, and therefore to separate and discard the cardboard of the container and the cover film such as + tick.

However, the lottery information needs to be printed on a site that is difficult to visually recognize, and is therefore limited to the folding polymerization sites at the four corners of the container. A container customer who knows the location of lottery information in this way peels only that portion, that is, only a part of the container, visually checks for the presence of information, and if the lottery information is not attractive, the entire film Without peeling off, the container was often dumped with cardboard and thin paper as one body, and the initial purpose was not necessarily obtained.

  Therefore, in a double-layer paper container composed of a cardboard as a substrate and a cover film that is thinner than that, a means for distributing a plurality of lottery information at random locations on the inner surface of the bonded laminate is used. In order to collect and acquire the deposit score, it is necessary for the container customer to peel the cover film completely.

In addition, letters, numbers, and patterns as lottery information are displayed by perforations that are not printed, embossed, or penetrated, and can be sensed by the tactile sensation of the fingertips as well as the normal. .

Further, the lottery information forming portion is surrounded by half cuts and / or perforations so that the lottery information can be easily separated from the cardboard as the substrate of the container, and the lottery information is collected and stored for a long period of time in the container consumer. Made it easier.

  As described above, since a plurality of lottery information is distributed and formed in the two-layer paper container, the consumer can obtain the lottery information formed in the container by using a packaged object such as food and drink. After ingesting the object, the cover film is completely peeled off to confirm its location, and all the lottery information is cut off. Therefore, the substrate blank material and the cover film of the container are surely separated and then discarded (collected).

The multiple lottery information displayed on the surface of the substrate-side blank base paper of the container (including the lid, the same applies below) is numbers, letters, designs, etc., which are printed, embossed (indented), or perforated that do not penetrate And is divided into easy-release states by perforations or / and half-cuts (or also referred to as half-cuts; hereinafter the same) that do not penetrate the contours of the displayed parts. A thin cover film (plastic or paper) is coated on the surface of the substrate side blank base paper so that it can be peeled off by partial adhesion to form a laminated base paper. Each blank is formed by cutting according to the developed plan view.

Alternatively, one or more pieces of lottery information are printed or embossed or displayed on the surface of the substrate-side blank that has been cut by individually stamping the half cut line portion, and the contour of the displayed portion is displayed. As described above, a perforation or / and half cut that does not penetrate is formed in an easily removable state, and a cover film is laminated on the substrate side blank so as to be peeled off by partial adhesion to obtain a blank.

About the blank laminated and cut by the above-mentioned methods, the four corners and the bottom contour are bent to form a three-dimensional container, and the bent portions of the four corners are respectively bonded to the front wall and the rear wall to form a three-dimensional container. By doing so, the container is obtained.

It is unclear whether each paper container (including the lid) thus obtained contains lottery information, whether it exists, or how many lottery information exists. The bento consumers who are served in the box will know this only after the cover film has been completely peeled off after meals, and will store the lottery information section until a predetermined amount is obtained. Thus, the paper container completely separates the blank material part not contaminated with food and the contaminated cover film part, both of which are separated and discarded, and the paper resource can be easily recycled.

Next, embodiments of the present invention will be described with reference to the drawings. In addition, the front-back and left-right direction of the container which concerns on this invention is a relative thing, and the side wall by which the connection piece was joined to the outer side among the side walls, such as four sides, is called a front side wall and a rear side wall.

1 to 5 show an example of implementation according to the present invention, and the planar shape is substantially square and a flange is formed on the upper edge, but the presence or absence of such a flange and the shape of the container are not limited thereto. . Further, although a rectangular container is illustrated, it is needless to say that it may be a hexagon or an octagon. The substrate-side blank B shown in FIG. 1 is cut from a cardboard or cardboard having a thickness of about 0.2 to 3.0 mm, and three fold lines 1, 2 and 2 are formed radially at the four corners, and each of the radial fold lines. Folded lines 3, 3, 3, and 3 that connect the base points and surround the bottom surface portion 11 of the container are formed in an indentation shape (also referred to as a half cut).

Further, in this substrate-side blank B, one or more lottery information N (for example, numbers) is printed or embossed or displayed on a random portion of the front surface by a perforation that does not penetrate to the backside, and surrounds the lottery information N portion. The contour is defined by a half cut 4 and / or a perforation 5 that does not penetrate, and can be removed without using a tool such as a scissors. Thus, by displaying the lottery information and the perimeter of the lottery by a half cut or a perforation that does not penetrate, the trace of the lottery information N or the like cannot be visually recognized on the back surface (outer surface in the container) of the substrate side blank B. ing.

A peelable adhesive 6 (for example, an emulsion-type adhesive “TX-1286” manufactured by Todate Kasei Kogyo Co., Ltd.) is partially provided on the lottery information N display surface (inner surface in the container) side of the substrate side blank B (FIG. 1). Is applied to the entire surface of the substrate-side blank B, and is a translucent or desirably opaque cover film F (for example, 2 to 25 μm) thinner than the blank B (in FIGS. 2 and 3). It is displayed as a speckled pattern.). The cover film F is made of paper or plastic, and preferably a plant-derived bioplastic film is suitable.

The blank B on which the cover film F is laminated as described above is three-dimensionally formed in a paper container through a usual folding and assembling process. That is, the blank B is three-dimensionally obtained by folding the folding lines 3, 3... In FIG. 1 at the same time, simultaneously folding the folding lines 2, 2. .. Are joined to the front and rear wall surfaces 12 and 12, respectively. In FIG. 2, reference numerals 13 and 13 denote wall surfaces on both sides, and flanges 15 are formed at the opening edges of the front and rear and both wall surfaces by folding the fold line 7.7. Although the container main body has been described above, the configuration of the container lid, the random arrangement of the lottery information, and the like are the same, and the description thereof is omitted.

  In the three-dimensional paper container, the lottery information N displayed on the inner surface of the substrate paper and the half-cut contour are concealed by the opaque cover film F or by the foodstuffs contained in the container. become. In this way, the lottery information N in a random arrangement may be confined in the two-folded connecting piece 14 at the four corners, so that the two-folded connecting piece 14 is also separated in order to obtain all the lottery information. It is necessary to confirm the location.

A consumer who purchases a container according to the present invention loaded with food, after eating and drinking the contents, separates the four-fold connecting pieces 14 and 14 at the four corners of the container from the front and rear wall surfaces 12 and 12, One end is grasped and peeled off from the substrate cardboard of the container. Thus, the concealed lottery information N is exposed, and the consumer presses the lottery information N part with a finger and cuts it out from the base side blank B along the four half cuts and the five perforations ( (Fig. 4) This lottery information N has a merit that, for example, a numerical value is displayed and the consumer can accumulate several numerical values and convert it into a product etc. when the required number of points is reached. Thus, the cover film F is peeled off from the consumer's container body and the substrate blank B of the lid, and the willingness to collect all lottery information is drawn out. In addition, the location of the lottery information is at random positions, and if the cover film is opaque, all of the lottery information N can be obtained only by completely removing the cover film. Therefore, the separate collection between the cardboard side of the container and the plastic film becomes more complete.

In the above, the lottery information N is displayed by printing or the like on the substrate-side blank B cut for forming the container.
(For example, 1 meter square) The surface of the base paper, a plurality of lottery information N is displayed on random parts, and a half cut for cutting is engraved on the contour, and the adhesive is partially applied to the surface. Similarly, it is also possible to laminate a long cover film so as to be peelable, and then to form a laminated blank B by forming fold lines 1, 2, 3, and 3 and cutting individual blanks B Is possible.

In addition, there is a blank raw material supplied from a paper maker or the like in a form in which a cover film F is detachably attached to a cardboard or a rectangular flat cardboard of 1 meter square or the like. When using this blank raw material (not shown), the film is peeled off once and the lottery information N is printed, and the contour is cut again by half-cut 4 and / or perforation 5. Although it is possible to affix a cover film, the lottery information N and its contour may be formed by embossing from the surface of the laminated paper without peeling off the attached cover film F.

An example of the method is shown in FIG. That is, the female mold M1 having the smooth surface 7 is brought into contact with the back surface side of the blank B, and the other cover film F side is pressed by the male mold M2 provided with the lottery information stamp 8 and the hollow outline blade 9 protruding from the surface. In this way, information cannot be read from the blank back surface (outer surface of the container), but can be read from the cover film side. Therefore, the object of the present invention is achieved in which the lottery information is provided at random sites and the consumer is made to peel off all of the cover film. It is also possible to form the male M2 lottery information stamp 8 as an assembly of pins, whereby concave Braille is obtained, and the eye person can also read by touch.

  The lottery information N is divided by half cuts 4 or perforations 5 so that it can be easily cut out, and since it is a small piece, it can be collected and stored over a long period of time. Even if the food and drink served in this container is low-priced, it is exchanged for an attractive product when the total number of collected pieces increases as the lottery information N corresponding to the value. If it can be done, it will have the effect of attracting continuous collection, and therefore willingness to purchase. At the same time, since the cover film F is completely peeled off from the paper material of the substrate-side blank, complete separation and collection are possible.

The paper container according to the present invention is a bowl for take-out lunches in the food service industry, such as a container for beef bowls or beetle bowls, a dish to serve curry rice at event venues, packaging containers for Frankfurt, Kushikatsu, okonomiyaki, takoyaki, etc. Used as food containers and dishes in department stores and supermarkets. Moreover, repeat demand for food and drink is expected from the expectation for the acquisition of products by accumulation of lottery information N.

In the plan view of the blank, the broken line and the adhesive application location are illustrated (Example 1) It is the (a) top view and (b) side view which showed the state which formed the lot information part by the half cut in the blank of FIG. 1, and coat | covered the upper surface with a cover film. FIG. 3 is a perspective view showing a state in which the upper end of the cover film is gripped and peeled from the paper container main body in a paper container formed by bending the blank of FIG. 2. It is the side view which showed the state which peeled off the cover film from the used paper container, pressed the lottery information exposed with the finger | toe, and cut out along the outline. It is side sectional drawing which shows the embossing from the surface (container inner surface) side in the blank with which the thick paper and the cover film are laminated | stacked.
