Description

  The present invention relates to a tetrahedron-shaped package, and more specifically, the wide flat rib is formed so that any one of the flat ribs of the tetrahedron-shaped package heat-sealed in the direction perpendicular to each other is easily formed. Further, the present invention relates to a tetrahedral package that can be reused as it is even if it is used on a dining table by forming a pouring path for the filling material.

  Conventionally, a general tetrahedral package (hereinafter also simply referred to as “Tetra Pak”) supplies a band-shaped packaging material to a forming and filling machine, first shapes a cylindrical body, and forms a barrel portion thereof. Then, the cylindrical body is horizontally sealed in a direction perpendicular to the longitudinal direction of the cylindrical body, and one side of the body is closed, and the contents are filled from the other side of the body, followed by It is obtained by applying a seal in a direction perpendicular to the horizontal seal to the other side of the barrel and sealing it, and cutting it individually within the width of each horizontal seal.

  It is well known that the tetrahedral package manufactured in this way has been used mainly for foods and drinks such as milk, cream, confectionery and the like, and has a compact and unique shape. . Moreover, as a method of taking out the filling from such a tetrahedral package, it is common to cut off the corners of the package with scissors and open it, but preparation of an opening instrument is required. Therefore, as a solution, for example, one of the flat ribs of the package is formed with a step having a different heat seal width, and the flat rib is placed on its edge so as to pass through the step. There is a technique in which an unsealed portion that forms a spout is formed by cutting along a straight line and leaving a non-opened portion at a part of the cut end, which is proposed in Patent Document 1.

JP 2000-72155 A

  However, when the opening part which becomes the spout described in the above-mentioned Patent Document 1 is formed, there is nothing that blocks the spout and the inner cavity of the package, and the packing in the package pops out when the flat rib is torn, There is a problem that the surroundings are easily soiled. Moreover, since there is nothing equivalent to the pouring nozzle to guide and control the flow when pouring out the filling material, the filling material may flow out at once. When this is used for a dining table etc., it will be necessary to carefully change a package body, and also becomes a factor which becomes inconvenient.

  The present invention has been made in view of the above problems, and when tearing flat ribs to form an opening to be a spout, it is difficult for the filler in the tetra-pack package to pop out, and the amount dispensed also when dispensing the filler It is an object of the present invention to provide a tetrahedral package that can be used in the same manner as, for example, a soy sauce jar when used on a table.

Means to solve the problem

That is,
(1) The tetrahedral package of the present invention is a tetrahedral package in which both open ends of the body of the cylindrical body are heat-sealed in directions orthogonal to each other, flat ribs are formed at both ends, and the filling is sealed. In the package, the seal width of any one of the flat ribs is formed wide and a non-seal part communicating with the lumen of the tetrahedron part is formed at a predetermined position of the flat rib as a filling channel. An opening notch that cuts across the non-seal portion is formed at the width side edge of the flat rib.
With such a structure, when carrying, the flat ribs can be easily moved while holding the wide side of the flat ribs, and since they are tetrahedral, they can be arranged in a stable posture even if they are served on a table. In addition, when forming the opening portion serving as the spout, the flat rib can be torn while narrowing the boundary between the non-sealed portion and the package body cavity portion communicating with the lumen with the fingertip, so that the scattering of the filler It is good because it becomes a package that does not generate.

(2) In the tetrahedral package according to (1), the sealing width of any one of the flat ribs is formed to be a width that is 2/5 or more of the height of the tetrahedral part of the package. This means that when the package is lifted, not only the tip of the finger but also the entire abdomen of the fingertip can be held firmly and the spout can be easily formed by tearing the non-sealed part. It is because of doing.

(3) The tetrahedral package according to (1) or (2) has a flat heat seal area around the non-sealed portion. As a result, it is possible to completely prevent the filler from leaking or seeping out to the outside of the package through the non-sealing portion. In addition, when the filling is poured out, it is easy to control the amount to be poured, and even if it is used on the table, it can be reused in the same way as for example a soy sauce jar.

(4) In the tetrahedral package according to (1) to (3), the periphery of the flat heat seal portion is formed as a corrugated seal region having grooves parallel to the ridges of the tetrahedron. As a result, the package is less slippery, the flat ribs are more easily squeezed, and tearing can be further facilitated.

(5) The tetrahedral package according to (1) to (4) is cut at a predetermined position on a longitudinal side edge of the wide flat rib in a direction reaching the inner cavity of the tetrahedron from the non-seal portion. A tearable auxiliary notch is formed.

(6) The tetrahedral package described in (1) to (5) has a substantially regular tetrahedral shape.

The invention's effect

In the tetrahedral package of the present invention, one side of the deformed rib that is the sealing part of the tetrahedron is wide, so that it can be arranged in a stable posture on the whole table etc. Can be easily reused. Moreover, when opening a spout, it can provide as a package body which a filling material does not scatter. Furthermore, when the filling is poured out, it is easy to control the amount to be poured, and even if it is used on the table, it can be reused in the same manner as a soy sauce jar, for example.
In addition, since the periphery of the non-seal part is double-wrapped with a flat seal and a corrugated seal, the filling does not ooze out through the non-seal part, and there is no stagnation, and when the spout is opened Can be provided as a tetrahedral package that can be smoothly cut.
