Description

The present invention relates to a food packaging body made of a plastic film for packaging substantially triangular food products such as cooking bread and confectionery bread, and more particularly to a food packaging body suitable for food having a small thickness such as cheesecake.

For example, Patent Document 1 discloses a food packaging body made of a plastic film as a packaging body of a substantially triangular food such as cooking bread or confectionery bread. Such a food packaging body is formed as a bag body by connecting two generally isosceles trapezoidal plastic sheets by welding or the like.

Such a conventional food package is usually manufactured by stacking two plastic films and fusing them along the oblique and upper sides of the leg trapezoidal shape. The two plastic sheets are connected by fusing. Thus, a bag body having an open lower side is formed. Then, an opening assisting belt such as a cut tape is provided along the center line of one plastic film. Further, an outer edge portion is provided on the bag body, and a cut is provided in the outer edge portion.

Triangular food is put into the bag, and the opening of the plastic sheet is folded and sealed. At this time, the cut tape appears along the side surface of the triangular pillar-shaped food. The film starts to break when the outer edge is cut, and is further opened with a cut tape.

Utility Model Publication No. 7-8238

Conventional food packaging bodies such as those described in Patent Document 1 are mainly used for thick foods such as sandwiches among triangular columnar foods. In particular, in the case of a sandwich, since 2 to 3 sets of sandwiches are put in one package, the thickness of the portion taken out at a time is small, and it can be taken out even with a relatively small opening.

However, in the case of confectionery such as cheesecake, since only one is contained in one package, all the contents are taken out at one time. Therefore, it is necessary to provide a wide opening assisting band that covers almost the entire width of the side surface by, for example, providing a plurality of cut tapes in parallel. However, since the notch of the outer edge (top) must be formed outside the width of the opening assistance band, the opening assistance band cannot be provided to the full width of the side surface of the bag. Therefore, in the packaging for cheesecake, a packaging body having a size considerably larger than the size of the cheesecake is used. This is a wasteful use of the material, and the appearance is poor in a storage state with a large gap.

An object of the present invention is to provide a food packaging body made of a plastic sheet that can be opened so as to form a large outlet and from which food can be easily taken out.

In order to solve the above-described problems, the food packaging body of the present invention is a food packaging body formed by superposing two plastic sheets, and is provided on an isosceles trapezoidal food storage section and the food storage section. It has a parietal portion, a food container is provided with an opening assistance band, an upper edge of the parietal portion is provided with a notch outside the width of the opening assistance band, and the parietal part is from above It has a shape that widens toward the surface. Furthermore, a bottom surface forming part is provided under the food container, and the bottom surface forming part is an isosceles trapezoid whose width increases from bottom to top, and the inclination angle of the side of the bottom surface forming part is on the side of the top of the head. It is preferably the same as the inclination angle of the side.

The food packaging body of this invention can be provided with a wide opening assisting belt, and the food inside can be easily taken out from the wide opening.

It is a top view which shows a food packaging body. It is a perspective view which shows the use condition of a food packaging body. It is a top view which shows the manufacturing method of a food packaging body.

A mode for carrying out the invention will be described with reference to the drawings. FIG. 1 is a plan view showing a food package. The food packaging body 1 of the present invention is formed by superposing two plastic sheets. It has an isosceles trapezoidal food container 2 and a top 3 provided on the food container 2. An opening assisting band 4 is provided along the center line from the food storage part 2 to the top of the head 3, and a notch 5 is provided outside the opening assisting band 4 at the upper edge of the top of the head 3. It has been. And the top part 3 is a shape which a width | variety spreads upwards from the bottom. Particularly in this example, the parietal portion 3 is an isosceles trapezoid, and its side has an inclination of an angle θ.

The two plastic sheets constituting the food package 1 are transparent or translucent, and are preferably heat-weldable so that the sheets can be bonded to each other by heating.

The main part of the food container 2 is substantially an isosceles trapezoid. The upper side portion 6 is provided with a sealing band 7 by heat welding or the like, and the side portion 8 is also closed by fusing or the like. On the other hand, the lower side portion 9 is not closed. The food container 2 is an isosceles trapezoid whose upper side 6 is narrower than the lower side 7.

In this example, a bottom surface forming part 10 is provided below the food container 2. The bottom surface forming portion 10 is an isosceles trapezoidal rib whose width increases from bottom to top. And the inclination angle of the side is the same as the inclination angle θ of the side of the top 3. Moreover, the height of the top 3 and the surface formation part 10 is also the same. The lower side portion of the bottom surface forming portion 10 is open.

Compared to a conventional triangular food packaging body such as Patent Document 1, the food container 2 of the present invention has a wide opening assisting band 4 having a wide width W1. The width W1 of 70% or more of the width W2 of the upper side portion 6 of the food container 2 can be set. For example, the width W2 of the upper side portion 6 can be 32 mm, the width W1 of the opening assisting belt 4 can be 25 mm, and W1 can be about 80% of W2. Such a wide opening assisting band 4 may be formed integrally, or may be formed by providing a plurality of cut tapes in parallel.

A pair of cut portions 5 are provided on the upper edge portion of the top portion 3, and the interval is W3. This interval W3 is wider than the width W1 of the opening assisting belt 4 and narrower than the width W2 of the upper side portion 6 of the food container 2. In this example, the interval W3 is 32 mm. In this case, if it is a rectangular top as shown in FIG. 7 of the patent document, it is only 1 mm away from the side edge, and it is not possible to provide a notch at this position. In addition, only a very thin opening assisting band can be used at the top of the head having a narrow upper side as shown in FIG. However, in this device, the upper edge of the top 3 is wide, and for example, its width W4 is 52 mm in this example. Therefore, since there is a sufficient distance from the side end even in such a position, the cut portion can be easily formed.

A packaging method using this food package will be described. FIG. 2 is a perspective view showing a use state of the food package. Open the lower mouth of the food package 1 and insert the food x. The present invention can also be applied to a relatively thin triangular columnar food. Here, food having a bottom surface of an isosceles triangle is suitable. Further, it may be a fan-shaped bottom surface having an external appearance close to that of a perfect isosceles triangle. The side surface (surface in the thickness direction) of the food x is set to face the center of the food container 2. Then, the mouth is folded and sealed, and fixed with an adhesive tape or the like. Thus, a packaging state as shown in FIG. 2 is obtained. The food packaging body having such a top-spreading head portion 3 has never been present, and the packaging state has a novel appearance.

Next, the opening of the food package will be described. If the center of the upper edge part of the top 2 is pinched with a finger and pulled downward, the fracture starts from the notch 5. And the opening assistance belt | band | zone 4 is peeled from the top part 3 and the food storage part 2, and the food packaging body 1 is opened.

Since the opening assisting band 4 is wide, a large opening is formed so that the side surface of the food x is almost exposed. The food x can be easily taken out from the wide opening thus formed. Even soft foods such as rare cheesecake can be taken out without being crushed or deformed.

Furthermore, the example of the manufacturing method of this food packaging body is demonstrated. FIG. 3 is a plan view showing a method for producing a food package. In the manufacturing method of this example, two sheets of plastic sheet original fabric y having the same width as the length in the longitudinal direction of the food package are used. Opening auxiliary bands 4 are previously provided at predetermined intervals on one of the two original plastic sheets with a cut tape or the like.

This two-ply plastic sheet original fabric y flows from right to left in FIG. By cutting this plastic sheet original fabric y along the cutting lines z1 and z2, a prototype of one food package is cut out. Here, paying attention to the cutting line z2 on the right side of FIG. 3, this cutting forms the outer shape on the right side of one food packaging body 1a and simultaneously forms the outer shape on the left side of the next food packaging body 1b. This is because the inclination angle of the side of the bottom surface forming portion is the same as the inclination angle of the side of the top of the head. Next to one food packaging body 1a, the next food packaging body 1b turned upside down is formed. The top surface portion 3 and the bottom surface forming portion 10 of one food packaging body 1a are adjacent to each other so as to nest the bottom surface forming portion 10 and the top surface portion 3 of the next food packaging body 1b. Thus, the shape of the food package 1 is efficiently formed. Further, the raw plastic sheet raw material y can be used efficiently without wasting it, and almost no dust is generated.

If the plastic sheet original fabric y is sent to the left by a distance L corresponding to two food packaging bodies and cut in the same manner, two prototypes of the food packaging bodies are cut out.

Here, if cutting by fusing is performed, the upper and lower plastic sheets can be connected along the cutting line. Thereby, the side part of the food accommodating part 2 can be closed, and a bag body is formed. If the sealing part 7 is formed by thermocompression bonding etc. with respect to the cut-out original form of the food packaging body, and the cut part 5 is further formed, a food packaging body will be obtained.

As mentioned above, according to the food packaging body of this invention, since the opening assistance belt | band | zone 4 wide enough with respect to the width | variety of the upper side of the food accommodating part 2 can be provided, it can open widely along the side surface of a triangular column-shaped foodstuff. . Therefore, the food can be easily taken out. Moreover, it is not necessary to make a food package of an excessive size with respect to food. Since it can be made to the size suitable for food, raw materials are not wasted and a beautiful packaging state can be realized. This food packaging body can be efficiently cut out and manufactured without waste from two stacked plastic sheet originals.
