JPS5848290Y2 - bobbin for thread - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a bobbin for thread.

Usually, in a resin thread bobbin, if the outer circumferential surface of the body is smooth, the winding start end tends to slip when winding the thread.

Therefore, a body with a partially satin-like outer circumferential surface is provided, but if you dare to form a minute uneven shape, you can combine advertising letters with the minute uneven shape. Security is also guaranteed - killing two birds with one stone.

The purpose of the present invention is to integrally form concave or convex advertising characters on the outer peripheral surface of the body, and to prevent threads from slipping on at least one of the advertising characters or other outer peripheral surface parts. By forming possible minute unevenness,
To provide a thread bobbin which prevents slippage at the winding start end of the thread and in which advertising characters appear in a timely manner when a consumer runs out of thread.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the invention will be described below with reference to the accompanying drawings.

The thread bobbin according to the present invention is integrally molded with a suitable synthetic resin, and consists of flanges 1, 1 and a body part 2, and on the outer peripheral surface of the body part 2 are advertising letters 3 in a concave shape. For example, "Thank you very much.

The words "Please use our products again next time" are integrally formed during resin molding.

The letters 3 are obtained by machining a molding die, and in this embodiment are formed in a convex shape on the outer circumferential surface, and minute irregularities are formed in the letter portions by texturing or the like.

This fine unevenness shape is provided exclusively for the purpose of preventing slippage at the end of the winding start of the yarn, and is, for example, a groove-like fine unevenness shape in which the yarn is caught.

The characters 3 may have a concave shape instead of a convex shape, and in this case, minute irregularities are formed on the bottom surface of the concave portion by texturing or the like.

Furthermore, minute irregularities may be formed on the outer circumferential surface other than the characters 3.

In terms of area, this method allows for a wider area of minute irregularities, so it has a better effect of preventing the thread from slipping.

Of course, the minute unevenness may be formed on both the outer peripheral surface and the character 3, but in this case, the pattern of the minute unevenness may be changed between the character 3 and the other outer peripheral surface.
It is necessary to make character 3 clearly distinguishable.

Therefore, according to the present invention, by combining advertising letters and minute irregularities, it is possible to prevent the end of the thread from winding from slipping, which not only makes thread winding easier, but also makes it possible to When the person runs out of yarn, promotional letters, etc. will appear at the right time, and the advertising effect will be excellent and the retention of customers will be guaranteed.

Furthermore, since the advertising letters are integrally formed during resin molding, no special process is required and productivity is not compromised in any way.

In addition, by adding an uneven shape such as texturing, the characters can be more clearly identified with the naked eye than when characters are simply formed using an uneven shape.
