JPH10337992A - Improved two-stage type thumbtack and stick sheet - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a thumbtack improved to easily take out the thumbtack without staining a stick sheet by metal rust and without damaging a finger tip in the case of bringing the sheet into close contact by a metal thumbtack to fasten the sheet, and a disc sheet for sticking. SOLUTION: A head flat surface part of a conventional general metal thumbtack is formed in a two-stage type. And, its lower stage part 2 is formed of material such as plastic or felt without rust and having slight elasticity, and a disc-like sheet smaller than its upper stage part 1 is adhered in the improved two-stage type thumbtack and disc sheets for sticking.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thumbtack having an improved flat head portion of a metal thumbtack and a material disc sheet for pasting.

[0002]

2. Description of the Related Art Heretofore, there have been common pushpins and color pushpins made of a general metal thumbtack or a plastic made of plastic for easy gripping. In addition, there have been metal pushpins in which the outer periphery of the head of the metal pushpin has been lifted up a little so that the pushpin can be easily removed, and there are pushpins in which the entire head is covered with vinyl to prevent rust on the pasted paper. It should be noted that the thumbtack having a two-stage flat head portion of a metal thumbtack was prepared by the present inventor on August 21, 1976.
According to the date of application for registration of utility model, public utility model has been publicized in 1953-5339, and has not been examined yet. These have the following problems. (A) It is difficult to remove a general metal thumbtack, and there is a problem that the sticker is easily detached and torn off because it is slightly floated without being attached to the sticker. In addition, there was a problem that rust on the metal surface stained the paper. (B) It is surprisingly difficult to push a plastic push pin until it grips the head and makes close contact with the sticker. In addition, the color thumbtack has a sense of instability in shape, has a small contact surface with the paper, and is insufficiently pressed. In addition, there existed a problem that all were not efficient in storing in a container bulky from a shape. (C) A thumbtack with a slightly raised outer periphery of a metal thumbtack is easy to remove, but has problems such as lack of stability in the state of being attached to the paper and its shape, etc. There is a problem that the paper sticks to the paper and stains the paper. (D) Thumbtack with the entire thumbtack head covered with vinyl has features such as rust does not adhere to the paper, but lacks simplicity in shape, and is difficult to manufacture, resulting in high cost. And so on. (E) Thumbtack with a two-stage flat part of the metal thumbtack has features such as simple shape and easy removal. However, there are manufacturing problems due to metal processing and rust on the metal surface. However, there was a problem in that it adhered to the paper.

SUMMARY OF THE INVENTION An object of the present invention is to provide a thumbtack and an attaching disc sheet which solve the above-mentioned problems.

[0004]

According to the present invention, in order to achieve the above object, the lower part of a thumbtack made of a metal thumbtack having a two-stage flat head portion is made of plastic or felt without rust. It is characterized by using a resilient material and pasting a thin disk-shaped sheet slightly smaller than the upper part.

[0005]

[Function] Even if the lower part of the metal thumbtack is attached to the sticker without any gap, the lower part of the metal thumbtack is made of plastic or felt. So that it can be attached with a soft touch without rusting the metal and sticking the paper. Also,
There is a gap between the sticker and the upper part, and it is easy to remove. The disk sheet made of felt is slightly elastic, and can be easily attached to the upper metal part without any particular processing.

[0006]

1 and 2, reference numeral 1 denotes an upper portion of a metal thumbtack head flat portion, and 2 denotes a metal upper portion having a diameter smaller than the outer periphery of the upper portion by about 1 mm and a thickness of about 1 mm. It is a lower part to which a material sheet such as a disc-shaped plastic or felt is adhered. Reference numeral 3 denotes a needle at the center of the metal thumbtack.
When the lower part is made of plastic, when attaching to the upper metal part, there is a metal center part and there is a convex part, so in addition to the needle hole in the center part, a processing such as providing a slight concave part on the sticking side or heat treatment Processing such as pasting is required. If the lower part is made of felt, it has some elasticity, so there is no need to perform processing such as providing a concave part in the center. One side of the felt as shown in FIG. By providing the disc, the sticker can be attached to a conventional metal thumbtack at the time of use and used as an improved two-stage thumbtack having the same effect as the present invention.

[0007]

According to the present invention, when the sticker is fixed with the metal thumbtack as described above, even if the thumbtack and the sticker are firmly attached, the lower part of the thumbtack is made of a material such as plastic or felt. It does not stain with rust, and can be adhered in a soft state without damaging the paper. In addition, by utilizing the gap between the upper part of the thumbtack and the sticker, it can be easily removed using a fingertip or a removal tool, and damage to the sticker or the thumbtack can be prevented. The design is simple in shape and there is a sense of stability. Further, the processing is easy only by sticking a disc-shaped material such as plastic or felt to a conventional general metal thumbtack, and the cost can be reduced. In addition,
When the lower part of the thumbtack is heat-treated with a material such as plastic and stuck, the fixing of the needle at the center of the thumbtack is reinforced and the support and fixing of the needle can be strengthened structurally.
