Description

The present invention relates to a method for manufacturing a package for packing tissue paper or the like using a film sheet.

When packing tissue paper, thick paper was used to manufacture a packaging box large enough to store hundreds of sheets of tissue paper, and the tissue paper was folded and stored in a bundle.
When tissue paper is bundled in units of several hundred sheets, considerable strength is generated. Therefore, there is a so-called pillow wrapping in which a resin film sheet is used instead of the above-mentioned thick paper.

The pillow packaging of tissue paper is designed to prevent the generation of cardboard box waste after the packaged tissue paper is used up, and is formed to be approximately the same size as the cardboard packaging box. The opening for taking out the tissue paper is also provided at a position substantially similar to that of the above-mentioned packaging box.

The opening of the pillow package is processed to provide perforated holes (holes of equal length and equal intervals) on the surface of the film sheet when the package is manufactured, and the opening is at the time of shipment from the factory. The part is sealed.
Further, when the user uses the tissue paper, the linear perforations are opened by hand so that the tissue paper can be taken out one by one or a set of two from the packing body (for example,). , Patent Document 1).

Further, in a pillow packing body using a resin film sheet, a lid flap is installed on the upper surface of the pillow packing body, and the lid flap is lifted so that an outlet can be opened along the perforation. (See, for example, Patent Document 2).

Since the packaging body using the conventional resin film sheet is configured as described above, when the sealed opening is opened by hand, the film sheet is stretched around the opening to which force is applied. There is a problem that a force for opening along the perforation must be applied while strongly pressing the periphery of the opening.
In addition, when the lid flap or the like is installed in a packing body using a resin film sheet in order to facilitate opening, the man-hours for joining the film sheet and the lid flap increase, and the manufacturing cost increases. There was a problem that it became difficult to actually carry out production and sales.

It has a second process and a third process of fixing a plurality of ends of a film sheet wrapping the thin leaf paper bundle to form a box-shaped or bag-shaped packing body , and the third process is the thin leaf paper. When the film sheet in which the bundle is wrapped is formed in the shape of a box or a bag, the plurality of ends are subjected to adhesive processing to provide joints on the side surfaces of the package to be arranged opposite to each other . In the process, the cutter is brought into contact with a predetermined position of the film sheet so that the perforations extending in the direction connecting the joints arranged opposite to each other are formed, and the joints arranged to face each other are joined. When the perforation is formed, the hole length is the longest in the central portion between the portions, and the hole length is gradually shortened toward the joint portion to be arranged so as to form the perforation. It is characterized in that the hole in the central portion between the joints is provided so as to have a length enough to accommodate one fingertip .

Further, in the first process, the rotation driving means is operated by bringing the cutter in which the plurality of thin blades are arranged on the outer peripheral portion of the support member rotated by the rotation driving means into contact with a predetermined position of the film sheet. It is characterized by forming perforated holes.

Further, in the fifth process, a cutter in which the plurality of thin blades are arranged is brought into contact with a predetermined position of the film sheet by using the elevating means to bring the cutter having the plurality of thin blades arranged at the lower end of the support member that elevates by the elevating means, and the holes in the perforations.
