Description

The present invention relates to a package for packaging food and the like, and an original fabric for a package used for manufacturing the package.

For packaging such as cooking bread and confectionery bread, a package called pillow packaging is used. The contents are put into an envelope-like bag formed by backing, and the mouth is sealed by thermocompression bonding or the like.

Patent Documents 1 to 3 describe a pillow package with folds, a method for manufacturing the same, a raw fabric roll, and the like. The raw roll is a wrapping material with pleats formed of a wrapping material having heat-sealing properties and extending in a band shape in a direction perpendicular to the continuous direction at a constant pitch. The pleats are formed by folding the inner surfaces into a palm shape and heat-sealing. By manufacturing the package so that the folds are aligned with the lower side of the pillow package, the lower part is fixed in a rectangular shape, and the pillow package is capable of self-supporting. In addition, since no pleats are provided on the upper side, it does not change from the mouth of a normal pillow package.

Japanese Patent No. 4060077 Japanese Patent No. 4118568 Japanese Patent No. 4118570

The envelope-shaped pillow package that has been used in the past is flat in its original shape, and only swells according to the outline of the contents when the contents are inserted. Since it does not maintain its own three-dimensional shape, it will be deformed if any force is applied, and will not protect the contents. If you want to wrap a square sandwich or the like, you need to use a separate packaging material such as a tray and put the tray inside.

In the pillow package described in Patent Documents 1 to 3, the lower part is reinforced by creases, and the shape of the rectangular parallelepiped can be maintained to some extent. Therefore, the packaging body can be erected by placing the side with the folds down. However, no crease is provided on the upper side, and the strength is not different from that of a normal pillow package. Therefore, the shape of the rectangular parallelepiped is not maintained at the upper part.

The pleats are formed by folding and heat-sealing the inner surfaces of the packaging material in the shape of a palm. Therefore, even if the folding is increased, only the base of the fold is connected to the main body of the package in a linear manner, and the effect of reinforcement is limited. If it is going to keep the shape of a rectangular solid firmly, you have to use a thick sheet | seat as a raw material of packaging material. Further, in the raw roll, the folds are formed over the entire width of the packaging material, and a space without folds cannot be formed in the edge portion. When doing a backrest, the edge folds also enter the backrest. In this part, six sheets overlap, making it difficult to back up, and only this part becomes strangely thick.

An object of the present invention is to provide a package that can be easily manufactured by pillow packaging and that can maintain the shape of a rectangular parallelepiped, and an original fabric therefor.

In order to solve the above-described problems, the packaging material of the present invention includes a belt-like continuous sheet, and a belt-like reinforcing sheet attached to the continuous sheet in a direction perpendicular to the length direction of the continuous sheet. The reinforcing sheets are provided in pairs at a predetermined distance, and the pairs of reinforcing sheets are repeatedly provided on the continuous sheet at regular intervals. Further, both ends of the reinforcing sheet in a direction perpendicular to the length direction of the continuous sheet do not reach the side edge of the continuous sheet, and a space is formed between the end of the reinforcing sheet and the side edge of the continuous sheet. It is preferable. Moreover, you may affix a reinforcement sheet along the length direction of a continuous sheet.

The package of the present invention includes a first surface having a backrest formed by joining the sheets, a second surface facing the first surface, and a first surface provided perpendicular to the first surface and the second surface. A quadrangular column is formed by the first surface, the second surface, the third surface, and the fourth surface, and sealing portions are formed at both mouth portions of the quadrangular column. In addition, reinforcing sheets are attached along both mouths of the square pillar. In addition, reinforcing sheets may be attached to the third surface and the fourth surface, respectively.

The reinforcing sheet is reinforced along the both ends of the rectangular pillars of the packaging body by the reinforcing sheet attached in a direction perpendicular to the length direction of the continuous sheet of the packaging body, and the packaging body forms a rectangular parallelepiped shape. be able to. It can be easily manufactured by pillow packaging with a backrest.

It is a top view which shows the original fabric for packages. It is the same part enlarged view. It is a perspective view which shows a package 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 packaging material.

The package fabric 1 includes a strip-shaped continuous sheet 2 having a constant width W, and a strip-shaped first reinforcement attached on the continuous sheet 2 along a direction perpendicular to the length direction of the continuous sheet 2. It has a sheet 3. The first reinforcing sheet 3 is provided so as to form a pair of two reinforcing sheets with a predetermined interval L1. And the pair of this 1st reinforcement sheet | seat 3 is repeatedly provided with the fixed space | interval L2 as a period.

The material of the continuous sheet 2 is not particularly limited, and may be a sheet having a normal strength as a packaging material, and may be appropriately selected from a plastic sheet, a paper sheet, or a composite sheet thereof. And the rigidity (stiffness) of this continuous sheet 2 does not need to be so strong. On the other hand, the reinforcing sheet 3 is preferably a material that is stronger than the continuous sheet 2. Here, a transparent plastic film widely used as a packaging material for food is used. And the reinforcement sheet 3 is affixed on the continuous sheet 2 by thermocompression bonding.

A pillow-shaped package having a rectangular parallelepiped shape is manufactured from the original fabric 1 for packaging, but the width W of the original fabric 1 for packaging, the interval L1 between the pair of reinforcing sheets 3, and the repetition period L2 of the pair are manufactured. It is determined based on the shape of the pillow package. FIG. 2 is an enlarged plan view showing the packaging material, and shows details for one cycle. The width W corresponds to the length obtained by adding the peripheral length of the package to be manufactured and the width required for the backrest 15. Moreover, the space | interval L1 between the outer sides between the pair of the reinforcing sheets 3 corresponds to the height of the package. And the repetition period L2 respond | corresponds to the length required in order to make one package.

Here, although the 1st reinforcement sheet 3 is provided over most of the width | variety of the raw material 1 for packaging bodies, it has not reached to the side edge of the continuous sheet 2. FIG. A space 4 in which the first reinforcing sheet 3 is not provided is formed in the vicinity of the side edge of the continuous sheet. The width of the space 4 is wider than the width used for the backrest 15.

A second reinforcing sheet 5 is attached to the package original fabric 1 along the length direction of the continuous sheet 1. Two second reinforcing sheets 5 are affixed, and their positions are set so as to be on the side surfaces of the package to be manufactured. The second reinforcing sheet 5 is also preferably a strong sheet. In this example, the same belt-like sheet as the first reinforcing sheet 3 is used.

The packaging material 1 can be wound around a bobbin and supplied as a material roll.

Next, the usage method of this raw material 1 for packaging bodies is demonstrated. The packaging material 1 is used while being pulled out from the bobbin. The surface on which the first reinforcing sheet 3 and the second reinforcing sheet 5 are attached is directed downward, and contents such as a cooking pan are placed on the surface on which the reinforcing sheets 3 and 5 are not attached. The side portions 6 of the continuous sheet 1 are overlapped with each other to form a backrest portion to form a quadrangular cylinder. The contents are stored in this cylinder. By preventing both end portions of the first reinforcing sheet 3 from reaching the side edges of the continuous sheet as in the example of FIG. 1, the first reinforcing sheet 3 does not enter the backrest portion, and the backrest is easily backed up. be able to. The formed backrest 15 has the same thickness over its entire length, and has an excellent aesthetic appearance.

While cutting at a position determined by the repetition period L2, the cut portion is sealed by thermocompression bonding or the like, and the sealing portion 16 is formed at both mouth portions of the quadrangular prism. The 1st reinforcement sheet 3 currently affixed is set so that it may become a position along both the opening parts of a square pole. In this way, a rectangular parallelepiped package 10 as shown in FIG. 3 is manufactured. At this time, the contents are stored in the package. That is, the manufacturing method of the package demonstrated here is also a packaging method.

Such packaging can be automatically performed by a bag making machine that is already popular. What is necessary is just to introduce the raw fabric 1 for packaging bodies of this invention, and it is not necessary to change an installation on a large scale.

Moreover, the bag body of the state which sealed only the one side of the opening part and opened the other may be manufactured, and the bag body may be provided. In this case, a similar package can be formed by putting the contents through the opening and sealing the mouth. The present invention can be used even by a small-scale business operator who does not have a bag making machine.

FIG. 3 is a perspective view showing the package. The package 10 includes a first surface 11 having a backrest portion 15 formed by joining the sheets, a second surface 12 facing the first surface 11, and perpendicular to the first surface 11 and the second surface 12. It has the 3rd surface 13 and the 4th surface 14 which were provided. The first surface 11, the second surface 12, the third surface 13, and the fourth surface 14 form a quadrangular prism. Sealing portions 16 are formed at both mouth portions of the rectangular column, and the package 10 is sealed. The 1st reinforcement sheet 3 is affixed so that the outer periphery may be enclosed substantially along both opening parts of a square pillar. This 1st reinforcement sheet 3 becomes frame | skeleton, and the package 10 has the substantially rectangular parallelepiped external shape as a whole. Therefore, even if a round hamburger or the like is stored, the package 10 can be placed in an upright state with the rectangular parallelepiped shape and the mouth portion down. Such a placement has not been possible with conventional pillow packages.

In the package of this example, the second reinforcing sheet 5 is attached to the third surface 13 and the fourth surface 14 which are side surfaces. The second reinforcing sheet 5 is provided in a direction parallel to the backrest 15, that is, from the upper part to the lower part. The third surface 13 and the fourth surface 14 are reinforced by the second reinforcing sheet 5, and support the quadrangular prism structure like the three columns together with the backrest 15.

In this invention, since the 1st reinforcement sheet 3 and the 2nd reinforcement sheet 5 are attached by sticking, the whole surface of a reinforcement sheet acts as a reinforcing material. Therefore, even if it is a comparatively thin sheet | seat, the shape of a rectangular parallelepiped can be maintained effectively.
