Description

  The present invention relates to a packaging method and a packaging bag in which a packaging material is wound around a supplied product.

  2. Description of the Related Art Conventionally, as a packaging form in which a product such as a souvenir or a lunch box is overwrapped with a packaging material, there is one that forms a body-wrapped packaging bag by winding the outer peripheral surface of the product. In general, many body-wrapped packaging bags are obtained by folding the side peripheral surface of a product with a packaging material and bonding the both ends of the packaging material on the bottom surface. That is, it is the structure which covers a product with a cylindrical packaging material. Such a waist-wrapping bag requires a small amount of packaging material and does not complicate the structure of the packaging device, so that the manufacturing cost and work time can be reduced. However, since this waist-wrapping bag is a packaging material folded in a cylindrical shape, it is easily displaced in the axial direction.

As a packaging method for solving the above problems, there is a configuration disclosed in Patent Document 1. The invention of Patent Document 1 is a body-wrapped body in which one end of a packaging material sheet is attached to an article with an adhesive and the other end is attached to one end with an adhesive. In other words, the adhesive sheet is applied to both end portions of the packaging material sheet, and one end portion is adhered to the article, thereby preventing the packaging material sheet from shifting.

  Now, in order to form the body-wrapped package of Patent Document 1, an adhesive (hereinafter also referred to as glue) must be applied to both ends of the packaging material. To achieve this with conventional devices, it is necessary to have a structure with two devices for applying glue, or a structure in which one glue applicator moves between both ends of the packaging material to apply glue. was there. In any case, it is inevitable that the structure of the apparatus becomes complicated, and costs and labor are required for the entire operation such as packaging and maintenance.

  The present invention has been made in view of such circumstances, and provides a packaging method and a waist-wrapping bag in which the packaging material is not likely to be displaced from the product only by applying the glue to the packaging material only partially. It is in.

In order to achieve the above object, the method of the present invention includes a glue application step of applying glue to an adhesive region set at one end of a band-shaped packaging material;
Place the middle part of the packaging material on the outer peripheral surface of the product, fold the other end of the packaging material not coated with glue from one side along the outer peripheral surface of the product, and then one end of the packaging material coated with glue A body winding step of folding a part from the other side along the outer peripheral surface of the product and superimposing the one end part on the other end part,
The adhesive region further includes a packaging material adhesion region that overlaps the other end portion of the packaging material and adheres the other end portion, and a product adhesion region that adheres to the outer peripheral surface of the product without overlapping the other end portion. Features.

  According to such a method, the product adhesion region adheres to the product, and the packaging material does not deviate from the product. Furthermore, the packaging material for forming the body-wrapped packaging bag applies the glue only to one end portion. Therefore, only one apparatus for applying the glue is required, and the packaging process such as the glue applying step is not complicated.

  Moreover, the packaging method of this invention can be set as the structure which a product adhesion | attachment area | region protrudes in the packaging material longitudinal direction from the superposition | polymerization part of the one end part and other end part of a packaging material. Thereby, the product adhesion region and the packaging material adhesion region are adjacent to each other. Accordingly, since the glue is applied across these two regions, it is possible to form a body-wrapped packaging bag in which the packaging material is adhered to the product and both ends of the packaging material are adhered.

  Furthermore, the packaging method of the present invention has an opening formed at the other end of the packaging material, and when one end of the packaging material is overlaid on the other end, the adhesive region facing the opening A configuration in which an adhesive region is formed may be employed. The product adhesion region at one end of the packaging material is directly adhered to the product through the opening at the other end of the packaging material, thereby preventing the packaging material from shifting. In addition, the adhesion region may be narrower than the above configuration, and the amount of glue applied can be reduced.

The body-wrapped packaging bag of the present invention is characterized by having the following configurations (a) to (c).
(A) A band-shaped packaging material is wound around the outer peripheral surface of the product, and one end portion of the packaging material overlaps the other end portion.
(B) The packaging material has a packaging material adhesion region in which one end and the other end of the packaging material are adhered by glue.
(C) One end portion of the packaging material does not overlap the other end portion, and has a product adhesion region bonded to the outer peripheral surface of the product by glue.

  The body-wrapped packaging bag having such a configuration is such that the paste is applied only to one end of the packaging material, and the packaging operation can be performed efficiently.

  Further, the body-wrapping bag may have a structure in which the product adhesion region is formed so as to protrude from the overlapping portion of the one end portion and the other end portion of the packaging material in the packaging material longitudinal direction. Further, an opening may be formed at the other end of the packaging material, and one end of the packaging material may be bonded to the outer peripheral surface of the product with glue through the opening to form a product adhesion region. .

  The waist-wrapped bag is one end of the packaging material, and forms a perforation in or around the product adhesion region, and one end of the packaging material separated from the perforation when the packaging material is peeled off from the product. It is also possible to adopt a configuration in which the portion remains adhered to the product. Since the packaging material remains adhered to the product by the perforation, it becomes easy to distinguish the product once the packaging material has been peeled off, and it is possible to prevent the unopened product from being delivered to the purchaser.

  As described above, the packaging method and the waist-wrapping bag of the present invention can wrap a product without shifting the packaging material only by applying the glue only to a part of the packaging material.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
