Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a dustproof reinforcing material provided inside the handle hole of a packaging box made of corrugated board.

BACKGROUND ART As a conventional saw dust-proof reinforcing material, for example, one shown in Japanese Utility Model Application Publication No. 190611/1983 is known. The dust-proof reinforcing material described in this publication consists of a resin sheet having through holes for reinforcing hand holes, and a film having a stretching force of five times or more is attached to one side of the resin sheet to cover the through holes. The surface of the side on which the handle is not attached is fixed to the inner surface of the handle hole forming portion of the packaging box using an adhesive.

Problems to be Solved by the Invention As mentioned above, a packaging box in which a resin sheet with a film attached is fixed to the inner surface of the handle hole forming part is such that the film prevents dust from entering through the handle hole. There is. When carrying this packaging box, one inserts a finger through the handle hole, stretches the film, and then hangs the film in the handle hole, but the film cannot be pushed and stretched sufficiently and the film is stretched around the finger. There was a problem that it took a lot of force to hold the handle, making it difficult to put your finger on the handle hole. In addition, when the packaging box is carried many times and the film is stretched by inserting a finger into the handle hole many times, there is a problem that the film cannot withstand its own stretching force and breaks.

This invention solves these problems,
The purpose is to make it easier to put one's fingers on the handle hole and to prevent the dustproof film from being damaged.

Means for Solving the Problem In order to solve this problem, the present invention provides a dust-proof reinforcing material provided inside a handle hole formed in a packaging box made of corrugated board, which fits in the handle hole. A synthetic resin film that is folded in the center in a bag-like manner is adhered to one side of a mount having holes.

Function With this configuration, since the film is provided in the form of a bag on the mount, the dust-proof reinforcing material is provided inside the handle hole of the packaging box, and the handle hole is reinforced by the mount, so that the film cannot be inserted into the handle hole. Even when hanging the film, the force required to push and stretch the film is not applied to the fingers as in the conventional case, making it easier to hang the film through the hand hole. Furthermore, since no finger force is applied to the film, the film is not damaged and the dust-proofing effect of the handle hole can be maintained for a long period of time.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the drawings.

Figures 1 to 3 show the order of how to make the dustproof reinforcing material according to the embodiment of the present invention.First, as shown in Figure 1, the mount 1 is connected in a band shape, and the mount 1 is connected in a belt shape along the longitudinal direction. A synthetic resin film 2 whose central portion is folded in the palm of each hand is pulled out in parallel, and as shown in FIG. 2, the film 2 is applied on one side of the mount 1 and both sides along the longitudinal direction are heat-sealed.
3, 3 is the seal portion. Holes 4 are formed in the mount 1 at equal pitches in the longitudinal direction and match the handle holes of a packaging box made of corrugated board, and as shown in FIG. 2, the mount 1 and the film 2 are heat-sealed.
As shown in FIG. 3, the material is cut between the holes 4 to form one dustproof reinforcing material.
At the same time as this cutting or after cutting, the mount 1 and the film 2 and the part 2 at the center of the film 2 that is folded together along the cut part 2
Heat seal a. 5 is the seal portion. As a result, a dustproof reinforcing material 6 is formed in which the film 2 is provided on the bag with respect to the mount 1. As shown in FIG. 4, this dustproof reinforcing material 6 applies the other side of the mount 1 to the inner surface of the portion where the handle hole 8 of the packaging box 7 is formed, and aligns the hole 4 with the handle portion 8. It is fixed to the inner surface of the forming part of the handle hole 8 with adhesive.

As described above, since the dust-proof reinforcing material 6 provided on the inner surface of the forming part of the handle hole 8 of the packaging box 7 is provided with the bag-shaped film 2, it is possible to prevent dust from entering the inside of the packaging box 7 from the handle hole 8. In addition, even when you put your fingers on the handle hole 8 to carry the packaging box 7, because the film 2 is bag-shaped, there is no force applied to your fingers to stretch the film as in the past. It is easy to put your finger on the hand hole 8. Moreover, the handle hole 8 is reinforced by the mount 1, and the strength of the handle hole 8 can be improved.

The mount 1 has a three-layer structure having a polypropylene layer in the middle and kraft paper layers on both outer sides, and the film 2 has a polyethylene film with vinyl acetate on the back side. Using a layered structure, the filter 2 is heat-sealed onto the mount 1 through the vinyl acetate layer of the film 2.

Effects of the invention As described above, according to the present invention, since the film is mounted on the bag on the mount, the dust-proof reinforcing material is provided inside the handle hole of the packaging box and the handle hole is reinforced with the mount. Even when the finger is placed in the hand hole in this state, the force for pushing and stretching the film is not applied to the finger as in the conventional case, making it easier to hang the finger in the hand hole. Furthermore, since no finger force is applied to the film, the film is not damaged and the dust-proofing effect of the handle hole can be maintained for a long period of time.
