Abstract

PURPOSE:To make it unnecessary to prepare a large space, and to wrap easily commodities having various sizes by providing a specifically constituted tearing- off perforation lines, folding lines and cuttings, to a long sized and a strip shaped sheet made of a card-board. CONSTITUTION:A long sized sheet 1 is made of a cardboard and has a shape of a long strap, and a large number of tearing-off perforations 2 are provided along a rectangular line to its longitudinal direction with a constant interval l. The long sized cardboard sheet 1 is cut off so that each cut sheet may have a required length L (integer time of l) and become a single wrapping material 1a, and then a box type cylinder body which consists of a bottom plane 4, a top plane 6 and a side plane 7 and also has two openings at its front side and back side, is formed by folding the cut sheet along each folding lines 8, 9, 10 and 11. After adhering an adhesive lid to a part of the side plane 7, a commodity 18 and a paper mount 20 on which another commodity 19 is placed, are put in it, for instance. Then, dent-stopper parts for the commodities 16, 16, 16 and 16, and 17, 17, 17, and 17 are formed by benting each cutting of four corners 12 and 13 by pushing edges by a finger, so that the folding lines 8 to 11 may stay at an inner side of the box cylinder.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a packaging material that can be used to easily package a plurality of canned goods, bottled products, and other products of the same or different types in a similar manner in place of a packaging box. It is something.

[Conventional technology]

Conventionally, in supermarkets and the like, canned goods, bottled goods, and other products purchased by customers that are difficult to carry around are packaged in packaging boxes that are selected according to the size and number of the products.

[Problem to be solved by the invention]

The conventional packaging box method described above requires packaging boxes of various sizes to be prepared and has the problem of requiring a relatively large space for storage. Also, it takes a long time to combine product sizes, etc.
In the end, there was a problem in that it was necessary to insert a filling such as padskin.

The present invention attempts to solve these problems. In other words, the present invention eliminates the need to prepare packaging boxes of various sizes, suffices with different types of materials, does not require a large space for storage, and can accommodate the size of the product. It is an object of the present invention to provide a packaging material that can be easily combined even when the materials are of different sizes.

(Means for Solving the Problems) In order to achieve the above object, the packaging material of the present invention is made of cardboard and consists of a strip-shaped elongated article, and the packaging material is made of cardboard and is arranged at regular intervals in the longitudinal direction of the elongated article. It has a large number of perforations for separation provided perpendicular to the longitudinal direction, and is made up of a glued surface, a bottom surface, both side surfaces, and a top surface, and forms a box-shaped cylindrical body with openings at the front and back. It has four folding lines provided in the longitudinal direction so as to be foldable, and further, the perforation is made close to the perforation at a portion where each of the perforations intersects with each of the folding lines. A cut of an appropriate length is provided parallel to the cut.

[For production]

According to the present invention, since the long object is made of cardboard and has a band shape, it is necessary to roll it up into a roll and unwind it when necessary. Since it has a large number of perforations for cutting off, it can first be cut off at the perforations at the required length depending on the size and number of packages to be packaged. Next, a box-shaped tube consisting of a glued surface, a bottom surface, both side surfaces, and a top surface is made so as to be bendable and provided in the longitudinal direction so as to form a box-shaped cylinder with openings at the front and back.
Since the packaging material has the fold lines of a book, fold the packaging material cut out at the perforations along those fold lines, and glue or staple the one side that is connected to the glue allowance side.
By attaching them together, it is possible to form a box-shaped cylindrical body that has a bottom surface, both side surfaces, and a top surface, and is open at the front and back.

Therefore, the products to be packaged are placed in the box-shaped cylinder.

The box-shaped cylindrical body has a notch of an appropriate length that is provided close to the perforation and parallel to the perforation in the portion where the perforation and each fold line intersect. The notches appear at the four corners of the opening. Therefore, if you press and bend the corners from the notches at the four corners so that each fold line of that part is on the inside, the stored products, etc. will be pulled out from the opening of the box-shaped cylinder. A product locking portion is formed so that the product is not removed.
