Description

  The present invention relates to a package. More specifically, the present invention relates to a package that can prevent unintentional breakage during manufacture of the package.

  Conventionally, packaging bodies in which contents such as solids or liquids are sealed have been distributed in the housing portions. Examples of such a package include powdered soups and seasonings such as instant foods, frozen foods, and chilled foods. As a method for producing such a package, a method is known in which a linked package is prepared and then separated into individual packages (see, for example, Patent Document 1).

  Recently, in order to improve the openability of the package, a package having fragile portions such as cuts and notches has been proposed (see, for example, Patent Document 2). Further, Magic Cut (registered trademark), half cut, laser processing, and the like are also known as a method of forming a fragile portion other than a cut or notch.

JP-A-2006-3032 Japanese Utility Model Publication No.57-058035

  By the way, fragile portions such as cuts and cuts can be formed by post-processing on the package containing the contents. However, it is extremely difficult to form weak parts such as Magic Cut (registered trademark) and half cut by post-processing on the package containing the contents. Therefore, it is common to process the sheet before forming the package in advance.

  On the other hand, when a sheet having a magic cut (registered trademark) or a half cut formed on the peripheral edge of the sheet is formed into a package by the method described in Patent Document 1, unintentional breakage occurs from the fragile portion along the vertical seal. There was a problem to do. This is because when the vertical seal is formed over the top and bottom of the package with the same width as the filling nozzle, tension is concentrated on the end (particularly the opening) of the vertical seal, and the fragile portion breaks. It is because it ends up. As a result, breakage occurs from the magic cut or the half cut along the vertical seal.

  The present invention has been made in view of the above problems. That is, the problem of the present invention is that unintentional breakage occurs even when a package is manufactured using a sheet in which a weak portion such as Magic Cut (registered trademark) or half cut is formed on the peripheral edge of the sheet. It aims at providing the package which is hard to produce.

  The present invention for solving the above-mentioned problems is a sealed package having a non-sealed side formed by folding in two and an isolation seal part separating the accommodating parts, and a weak part is provided on the side opposite to the non-seal side. The package body is provided and the end of the isolation seal portion does not reach the fragile portion.

  According to such a structure, since the edge part of the isolation | separation seal | sticker part has not reached to the weak part, when a seal | sticker package is shape | molded, a tension | tensile_strength and heat are not applied to a weak part. As a result, it is possible to prevent unintended breakage from occurring along the isolation seal portion from the fragile portion.

  In the package, the fragile portion is preferably half cut, magic cut (registered trademark) or laser processing. Moreover, it is preferable that the accommodating part is sealed by the seal | sticker edge provided facing the non-seal edge | side. Furthermore, it is preferable that two or more accommodating portions are provided.

  According to this configuration, it is possible to provide a package with improved openability.

  According to this invention, a package can be shape | molded using the sheet | seat in which the weak part was formed. Thereby, the package body in which easy-openability was improved can be provided. In addition, it is possible to provide a package that hardly causes unintended breakage during the production of the package.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments for carrying out the invention will be described in detail with reference to the drawings as appropriate. In addition, the same code | symbol is attached | subjected to the part of the same name.

  FIG. 1 is a front view of a package according to the present invention, in which (a) is a package before filling the contents, and (b) is a package in a product form filled with the contents.

  The package 100 is made of a non-permeable packaging sheet material. As the non-permeable packaging sheet material, for example, a synthetic resin film such as nylon, polyethylene, polypropylene, polyester, or polyethylene terephthalate, or a film obtained by laminating these, a metal such as aluminum or copper, Examples include aluminum foil.

  The packaging body 100 according to the present invention is accommodated by a non-seal side 110 formed by folding a continuous packaging sheet material in half, and an isolation seal part 120 provided in a direction orthogonal to the non-seal side 110. This is a sealed package in which a portion 130 is formed.

  The weak part 140 is provided in the peripheral part of the non-permeable packaging sheet material used in the present invention. Examples of the fragile portion 140 include Magic Cut (registered trademark), half cut, laser processing, and the like. Moreover, the weak part 140 may be provided in all the peripheral parts of the packaging sheet raw material, and may be provided only in the one part peripheral part.

  The isolation seal part 120 is a seal part for separating the accommodating part 130, and is formed at a predetermined interval. The isolation seal portion 120 is formed from the non-seal side 110 to directly below the fragile portion 140, but a gap d is formed between the end portion of the isolation seal portion 120 and the fragile portion 140. The gap d between the end of the isolation seal portion 120 and the fragile portion 140 is preferably 1 to 10 mm, and more preferably 1 to 5 mm.

  The contents are enclosed in the accommodating portion 130 surrounded by the isolation seal portion 120 and the non-seal side 110. In addition, the package 100 according to the present invention is used as a final product by sealing the housing portion 130 with a seal side 150 that is finally provided to face the non-seal side 110.

  The final product can be used as an accessory for products such as instant food, chilled food, and frozen food. Examples of the contents include powder soups, liquid soups, ingredients, seasonings made of powdered granules such as savory chili, yam, and pepper.

  Next, the manufacturing method of the package 100 according to the present invention will be described. Here, as an example, a package 100 in which two storage portions 130 filled with contents are connected as an end product will be described.

  FIG. 2 is a schematic explanatory view showing a bag making and filling machine 400 that manufactures the package 100 according to the embodiment of the present invention.

  The bag making and filling machine 400 includes a sheet roll 410, a vertical sealer 420, filling nozzles 431 and 432, a horizontal sealer 440, and a cutter 450. The packaging sheet material 200 discharged from the sheet roll 410 by the bag making and filling machine 400 is finally fed with the contents via the vertical sealer 420, the filling nozzles 431, 432, the horizontal sealer 440, and the cutter 450, respectively. Products are manufactured sequentially.

  The sheet roll 410 is obtained by winding the packaging sheet material 200 in a roll shape. Here, the packaging sheet material 200 is not particularly limited as long as it is a heat-sealable material, but for example, a synthetic resin film such as nylon, polyethylene, polypropylene, polyester, or polyethylene terephthalate, or a film in which these are laminated. Alternatively, an aluminum foil or the like obtained by vapor deposition of a metal such as aluminum or copper may be used. The packaging sheet material 200 is continuously conveyed while being drawn from the sheet roll 410.

  Before reaching the vertical sealer 420, the wrapping sheet material 200 is folded in two while being conveyed so that a crease comes in the direction along the conveyance direction. At this time, the folded portion (non-seal side 110, see FIG. 1) folded in two is positioned below, and the top is open.

  Filling nozzles 431 and 432 are inserted into the folded folding sheet material 200 and heat sealed in the vertical direction by the vertical sealer 420. Thereby, the accommodating part 130 (refer FIG. 1) is formed.

  Here, the structure of the vertical sealer 420 will be described in more detail with reference to FIGS. 1 (a) and 3 (a), 3 (b). The vertical sealer 420 applies heat to the packaging sheet material at the heat seal surface 421 and forms the isolation seal portion 120 by thermally welding the packaging sheet materials. A vertical sealer 420 for manufacturing a package according to the present invention has a structure having a defective portion 422 in a part of the heat seal surface 421. By providing the defect portion 422, heat is not applied to the packaging sheet material at a position corresponding to the defect portion 422, and the packaging sheet materials are not thermally welded to each other. That is, the isolation seal portion 120 does not reach the fragile portion 140 due to the missing portion 422.

  Further, by providing the defect portion 422, a gap is not formed between the side surfaces of the filling nozzles 431 and 432 and the packaging sheet material 200 (that is, tension is applied to the packaging sheet material 200 in a direction parallel to the conveyance direction). Even if the isolation seal portion 120 is formed with the filling nozzles 431 and 432 being sandwiched (in the state of being applied), there is a space around the opening by the amount of the missing portion 422. For this reason, the opening (particularly, the fragile portion 140) is not subjected to tension or heat, so that unintended breakage from the fragile portion 140 can be prevented.

  The defect portion 422 is not particularly limited as long as the isolation seal portion 120 does not reach the fragile portion 140, and the design can be changed as appropriate. In FIG. 3B, the missing portion 422 is provided in any of the vertical sealers 420, but the missing portion 422 may be provided only in one of them.

  On the other hand, as shown in FIG. 4A, in the case of the vertical sealer 720 having no defect portion, the packaging sheet materials are heat-welded on the entire heat seal surface 721. Therefore, as shown in FIG. 5, the isolation seal portion 120 reaches the fragile portion 140. Further, as shown in FIG. 4B, a gap is not formed between the side surfaces of the filling nozzles 431 and 432 and the packaging sheet material 200 (that is, in a direction parallel to the conveying direction with respect to the packaging sheet material 200). If an attempt is made to form the isolation seal 120 while the filling nozzles 431 and 432 are sandwiched (with tension applied), the tension is concentrated at the end of the isolation seal 120. And when the tension applied to the end of the isolation seal part 120 exceeds a certain threshold value, an unintended breakage occurs from the fragile part 140.

  In addition, as a method for preventing the isolation seal portion 120 from reaching the fragile portion 140, a method in which a heat insulating material is sandwiched between the packaging sheet material 200 and the packaging sheet material 200 is conceivable. It is considered that unintentional breakage from the fragile portion 140 occurs because the tension concentrates on the end portion of the material.

  Next, the formed container 130 is filled with contents from the filling nozzles 431 and 432. Although simplified in FIG. 1, a plurality of vertical sealers 420 and filling nozzles 431 and 432 may be provided and move in synchronization with the speed at which the packaging sheet material 200 is conveyed. Also good. Note that the packaging sheet material 200 thus filled with the contents is referred to as a connected package 210 in the subsequent steps.

  The connection package 210 is sealed at its upper end by the horizontal sealer 440, thereby sealing the housing portion 130. At this time, as shown in FIG. 1B, the end of the horizontal sealer 440 and the end of the packaging sheet material 200 provided with the fragile portion 140 are aligned, and the end of the isolation seal portion 120 is located. Is preferably included so as to be included in the seal width of the lateral seal.

  In addition, before sealing with the horizontal sealer 440, an upper end may be preheated with a heater. By preheating with a heater, sealing with the horizontal sealer 440 can be performed reliably. The position where the connected package 210 is preheated by the heater is not particularly limited as long as it is sealed by the vertical sealer 420 and before sealing by the horizontal sealer 440.

  The connected package 210 whose upper end is sealed by the horizontal sealer 440 is cut by the cutter 450 to complete individual packages 100.

  In the said Example, although the package body which two package bodies connected was demonstrated to the example, this invention is not limited to this. For example, the packages may not be connected, and conversely, three or more may be connected.
