Description

Description: TECHNICAL FIELD The present invention relates to a method for manufacturing a string hook used to close a lid (also referred to as a flap or a folding lid) in a large envelope, document bag, cardboard box or the like. .

[Conventional technology]

As this kind of string hook, a hook board made of synthetic resin is heat-fused only at the central portion of the stick board made of synthetic resin having a pressure-sensitive adhesive layer on the back surface, so that the hook board It is known that a hanging concrete having a string winding gap is formed between the sticking base and the sticking base, and two hanging concretes are made into a set and one end of the hanging rope is fixed to the central portion of one hanging concrete ( See Japanese Utility Model Laid-Open No. 60-175041).

[Problems to be Solved by the Invention]

Since the above-mentioned string hooks are a pair of hooks with hooks and hooks without hooks, it is preferable to make a pair of hooks when supplying them to the market.

Therefore, if the hanging concrete with the string and the hanging concrete without the string are manufactured separately, it is not efficient because it is necessary to wrap the hanging concrete in one set.

The present invention has been proposed in view of the above points, and an object of the present invention is to provide a method for efficiently manufacturing a string hooking device including a pair of hooking members.

[Means for Solving the Problems]

In the present invention, a step of making notches along the outer shape of a sticking substrate in two rows along the longitudinal direction of a rectangular synthetic resin sheet for a sticking substrate covered with a release paper with a pressure-sensitive adhesive on the back surface, A step of making a notch along the outer shape of the hooking board in the synthetic resin sheet for the hooking board having the same shape and size as the above-mentioned synthetic resin sheet for the sticking base material, and the longitudinal direction of the above-mentioned synthetic resin sheet for the sticking base material. A process of placing one hanging string so as to pass through the center of each of the two sticking base materials, one set of two sticking base materials arranged in the direction orthogonal to each other, and hooking the synthetic resin sheet for the sticking base material. A step of stacking a synthetic resin sheet for a board so that the centers of the sticking base material and the hanging board coincide, a step of heat-sealing the central parts of the sticking base material and the hanging board that are vertically stacked,
A method of manufacturing a lid closing cord hooking device comprising a step of removing scraps of a synthetic resin sheet for a hooking board.

〔Example〕

In the case of the document bag 20 shown in FIG. 6, for example, in the case of the string hook manufactured by the manufacturing method of the present invention, the hanging concrete A having the hanging strap 8 is stuck to the center of the lid 21 by the sticking base material 2 to form a bag. Attach the other hanging concrete B in the same manner at the position corresponding to the above hanging concrete A at the upper end of the back surface of the main body,
Wrap the hanging string 8 around both hanging concrete A and B.

In the case of a cardboard box with a folding lid, the concrete A and B are placed side by side by hanging them on the end of the lid and the upper end of the side surface of the body, or in the case of a double-opening lid, at the corresponding position of the end of each lid. The above is the same as the conventional one.

The present invention resides in a method for manufacturing the above-described lid closing cord hanging device. Hereinafter, embodiments will be specifically described with reference to the drawings.

First step: As shown in FIG. 1, a rectangular synthetic resin sheet 1 for a sticking base material is used in which a pressure-sensitive adhesive on the back surface is covered with a release paper 7. Only the sheet 1 is provided with circular cuts 3 along the outer shape of the sticking substrate 2 in two rows along the longitudinal direction of the sheet. The drawing shows 8 notches. In this case, the perforation 4 in the longitudinal direction and the right angle to the longitudinal direction are arranged so that the two release base materials 2 penetrating the synthetic resin sheet 1 along the longitudinal direction of the sheet 1 form a set. It is advisable to insert perforations 5 in the direction.

Second step: Similarly, as shown in FIG. 1, two sticking base materials 2, 2 arranged in a direction orthogonal to the longitudinal direction of the synthetic resin sheet 1 for sticking base material are set as one set, and one sticking base is set in the longitudinal direction. One hanging string 8 so that it passes through each center of material 2.2
Put.

Third step: Use a semi-rigid or rigid synthetic resin sheet 11 for a hooking board having the same shape and size as the synthetic resin sheet 1 for a sticking substrate. On the sheet 11, a hooking board notch 13 having a size equal to or smaller than the sticking base material 2 is made at a position corresponding to the cut 3 of the sticking base material. The notch 13 may be cut, for example, in a perforated shape so that the latch plate 12 does not fall off.

Fourth step: A sheet 11 made of a synthetic resin for a latch is placed on the sheet 1 made of a synthetic resin for a sticking substrate so that the centers of the substrate 2 for a latch and the plate 12 for the latch are aligned with each other.

Fifth step: the sticking base material 2 and the hanging board 12 which are vertically stacked,
As shown in FIGS. 2 and 3, the mold electrode 16 is applied to the central portion 15 of the surface of the latch plate 12 for high-frequency adhesion, or a heating mold is pushed up for fusion. In this case, two, four or more pieces may be collectively heat-fused at the same time. By heat-fusing the sticking base material 2 and the latching board 12 at the central portion 15, a strap is attached to the central portion 15. 8 is tightly fixed, and a string wrapping gap g is formed between the sticking base material 2 and the hooking board as shown in FIG. FIG. 3 shows a state in which the fifth step is completed.

Sixth step: The scrap 14 which is an unnecessary part of the synthetic resin sheet 11 for the latch is removed. FIG. 4 shows the state after the removal. Here, the strap 81 between the pair of latching plates 12 to which the strap 8 is attached may be cut.

In addition, although the case where the string hooks of the set of Example 4 are aligned is illustrated, a large number can be obtained by using the synthetic resin sheet 1 for the sticking base material, the synthetic resin sheet 11 for the hooking board, and the like as a strip-shaped long object. In some cases, the string hooks are manufactured in a continuous state.

[Operation and effect of the invention]

According to the method for manufacturing a string hook of the present invention, a pair of hooks A and hooks A can be alternately formed on one release paper along the longitudinal direction thereof. It can be manufactured in a continuous state.

Therefore, the string hook can be stored in the packaging bag as it is and supplied to the market, which is efficient.

Further, even when a large amount of strap hangers are used, there is no possibility of causing inconvenience such as the number of hangers not being matched.
