JP2000211633A - Dustproof label for corrugated fiberboard box - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reduce frictional force of a dustproof label with an adhesive applied on a rear of a base to prevent the label from peeling by providing a layer comprising a material with low frictional force on a surface of an extensible film laminated on a surface of the base to close an opening of the base corresponding to a hole of a corrugated fiberboard box. SOLUTION: The dustproof label 1 comprises a mount 2 (base) having an opening 2a opened according to a hole of a corrugated fiberboard box, a polyurethane film 3 laminated on a surface of the mount 2 to close the opening 21, an adhesive 4 applied on a rear of the mount 2, a silicon layer 5 (a layer comprising a material with low frictional force) applied on a surface of the film 3 and a release paper 6 stuck to the adhesive 4. Thus the silicon layer 5 is less viscous and more slidable on surface than the film 3 made of polyurethane. Therefore frictional force between the dustproof label 1 and the corrugated fiberboard box can be reduced, thereby reliably preventing the dustproof label 1 from peeling.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dustproof label for a cardboard box for closing a hole for carrying the cardboard box.

[0002]

2. Description of the Related Art Usually, both sides of a cardboard box are provided with holes for inserting hands for convenience of transportation.
However, this hole also allows foreign substances to enter the cardboard box from the outside at the same time, which may cause a problem depending on the contents of the cardboard box. For example, when the container is a medicine or a precision machine, there is a possibility that quality deterioration or failure may occur.

[0003] For this reason, when storing medicines and the like,
Use a cardboard box that does not have holes from the beginning, or
It is conceivable to close the hole with a label or the like, but doing so makes it impossible to insert a hand, which makes transporting the cardboard box inconvenient. Therefore, a dust-proof label that can be inserted into the hole while closing the hole of the cardboard box has been proposed. This will be described with reference to FIG.

[0004] The dustproof label 100 is a backing paper 10 having an opening 101a provided corresponding to a hole of a cardboard box.
1, a film 102 laminated on the front surface of the mount 101 so as to cover the opening 101a, an adhesive 103 applied on the back surface of the mount 101, and a release paper 104 attached to the adhesive 103; In particular, a material having high stretchability such as polyurethane or latex is used as a material of the film 102. And the dustproof label 100 is
After peeling off the release paper 104, the opening 101 a is adhered to the cardboard box with an adhesive 103 and used while aligning the opening 101 a with the hole of the cardboard box. As a result, the hole of the cardboard box is closed by the film 102, and foreign substances are prevented from entering the cardboard box.

On the other hand, a film 1 made of polyurethane or the like
02 has excellent stretchability, so that the film 10
If one attempts to insert a hand into the hole of the cardboard box closed by 2, the film 102 stretches without tearing, and the hand can be inserted into the hole in the same manner as without the film 102. The inconvenience of can be solved.

[0006]

However, in the conventional dustproof label 100, when a large number of cardboard boxes are stacked and transported together by truck or the like, when adjacent cardboard boxes rub against each other due to vibration, the friction is caused by the friction. There is a problem that the dust-proof label 100 itself is easily peeled off. The cause of this problem is particularly the material of the film 102. This is because the material having high stretchability used as the film 102 has stickiness on the surface at the same time and easily generates a large frictional force.

Accordingly, it is an object of the present invention to provide a dust-proof label for a cardboard box that is difficult to peel off.

[0008]

According to the present invention, there is provided a base material having an opening provided corresponding to a hole of a cardboard box,
An extensible film laminated on the surface of the base material so as to cover the opening, and an adhesive applied to the back surface of the base material, in a dust-proof label for a cardboard box, the surface of the extensible film And a dust-proof label for a cardboard box provided with a layer made of a material having low frictional force. According to this means, by providing the layer made of the material having a low frictional force, even if the stacked cardboards rub against each other, the frictional force generated on the surface of the label is small and the label becomes slippery. In addition, peeling of the label can be prevented.

In the present invention, examples of the material of the substrate include paper and plastic films. In addition, examples of the stretchable film include a polyurethane film and a latex film.
Furthermore, examples of the adhesive include a pressure-sensitive adhesive and a heat-sensitive adhesive. Examples of the material having a low frictional force include silicon and a nitrified cotton polyamide-based resin.

[0010]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1A is a plan view of a dustproof label 1 for a cardboard box according to the present invention.
(B) is sectional drawing which follows the line AA of FIG. The dustproof label 1 has an opening 2a provided corresponding to the hole of the cardboard box.
A mounting sheet 2 having a base material (a base material in the claims), a polyurethane film 3 laminated on the surface of the mounting sheet 2 so as to close the opening 2a, and an adhesive 4 applied on the back surface of the mounting sheet 2;
It comprises a silicon layer 5 (a layer made of a material having a low frictional force in the claims) provided on the surface of the film 3 and a release paper 6 adhered to the adhesive 4.

FIG. 2 is a diagram showing an embodiment in which the dust-proof label 1 is attached to a cardboard box 10. The dustproof label 1 is made of release paper 6
Is peeled off, and is adhered by the adhesive 4 while aligning the opening 2a with the carrying hole provided on the side surface of the cardboard box 10.

The cardboard box 10 to which the dust-proof label 1 has been attached in this manner is, due to the presence of the film 3 of the dust-proof label 1,
External foreign matter is prevented from entering the inside of the box through the transport hole.

When transporting the cardboard box 10,
When trying to insert a hand into the opening 2a, the film 3 is stretched without breaking. As a result, the hand can be inserted into the transport hole of the cardboard box 10, and transport is facilitated.

On the other hand, when stacking and transporting the cardboard boxes 10 to which the dust-proof labels 1 are adhered, a frictional force is generated between the cardboard boxes 10 due to the vibration during transportation, and the dust-proof labels 1 and other cardboard boxes or A frictional force may be generated between the cardboard box and a dustproof label attached to another cardboard box.

However, the dustproof label 1 is provided with a silicon layer 5 on the surface, and the silicon layer 5 has a smaller surface stickiness and the like than the film 3 made of polyurethane and is slippery. For this reason, the frictional force between the dustproof label 1 and other cardboard boxes is very small, and the dustproof label
Escape 1 peeling.
