Abstract

(57) [Summary] [Problem] To form a predetermined shape without wrinkles or distortions in the sealing portion of each packaging bag even if the opening portions of a plurality of packaging bags are connected and sealed at once after storing the articles. Provide a continuous packing bag that can be used. SOLUTION: In a continuous packaging bag in which a plurality of packaging bags are connected in parallel at a horizontal sealing portion thereof, a half-cut portion capable of individually separating the packaging bags in a substantially central longitudinal direction of the horizontal sealing portion. And a predetermined area on a line of the half-cut portion is formed as a cutting portion.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a continuous packaging bag in which a plurality of packaging bags are connected in parallel.Specifically, after the items to be stored are stored in the bags, the openings of the bags can be efficiently heat sealed without wrinkling. A continuous packaging bag.

[0002]

[Prior art]

 Conventionally, two sheets made of synthetic resin, metal, or the like are formed as a packaging bag by overlapping and sealing the periphery thereof, or a plurality of sheets are connected at the lateral sealing portion of these packaging bags, A side-by-side packaging bag provided with a half cut (perforation or the like) that allows the bags to be individually separated at the connection portion is known.

[0003] However, in order to efficiently manufacture the parallel connected body of a plurality of bags (hereinafter simply referred to as a continuous packed bag), all the bags are opened after the objects to be stored are stored in the respective packing bags. Since it is formed using the technique of sealing the parts all at once, if the object to be stored has irregularities or irregular shapes, it will be inserted from the inside of the bag after being stored in the packaging bag. And it was difficult for the whole shape of the continuous packaging bag to be uniform.

[0004] Therefore, if the opening of each packaging bag is sealed at once in this state, wrinkles are generated in the sealing portion due to the degree of bulging of the bag body, or the sealing portion is distorted, so that a beautiful sealed bag is obtained. It was difficult to obtain as a packed product.

[0005]

[Problems to be solved by the invention]

 The present invention relates to a linked package that can form a predetermined shape without wrinkles or distortions in the sealing portion of each packaging bag even if the opening is sealed at once with a plurality of packaging bags connected after storing the articles. Try to get a bag.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the continuous packaging bag of the present invention is a continuous packaging bag in which a plurality of packaging bags are connected in parallel at their horizontal sealing portions. A half-cut portion is provided for individually separating the bags, and a predetermined area on the half-cut portion line is formed as a cut portion.

[0007] Here, the half-cut portion is provided with a cut, for example, in which approximately half of the perforation or the thickness of the sheet material can be separated by applying a specific tensile stress, so that each packaging bag can be separated. Part.

[0008]

[Embodiment of the invention]

 FIG. 1 is a plan view showing an embodiment of the continuous packaging bag according to the present invention, which is formed by stacking two sheets of aluminum foil coated with a synthetic resin and sealing a predetermined portion. .. Show a state in which the irregularly-shaped objects 1... 1 are sealed and stored in the individual packaging bags 6. Each of the packaging bags 6, 6, 6, ... is connected in parallel by a sealing section 2, 2, 2, ... provided with a half-cut section 4, 4, 4, ... capable of separating the packaging bags. Are provided with cutting portions 5, 5, 5,... On the half-cut portions 4, 4, 4, ... to which the tensile stress of the convex portions of the stored objects 1, 1, 1, ... is applied. ing. The cutting portions 5, 5, 5,... Are provided here because of the tensile stress from the inside of the packaging bag 6, 6, 6,. Are distorted due to the tensile stress from the inside of the packaging bags 6, 6..., And wrinkles occur when the openings 3, 3, 3,. , Etc., these stresses are absorbed by opening the cutting portions 5, 5, 5,... So that the shapes of the packaging bags 6, 6, 6,. .

[0009] As a result, the continuous packaging bag A keeps the objects 1... 1 stored in the respective packaging bags 6, 6,. ····································································· is manufactured as a bag-packed product of items to be housed without causing wrinkles or distortions in the sealed portion even if 3 is sealed at once.

[0010]

[Effect of the invention]

 In the continuous packaging bag of the present invention, a predetermined area on the line of the half-cut portion that allows each packaging bag to be individually separated is formed as a cutting portion. Without sealing, each opening can be sealed at once without wrinkles in a state where a plurality of packaging bags are connected.

[0011] Accordingly, the production efficiency can be greatly improved, which can contribute to a reduction in manufacturing and sales costs of the packaging bag.
