Abstract

The present invention does not form the wrinkles formed on the rubber gloves in the longitudinal direction of the rubber gloves, but gathers the uneven protrusions in the form of oblique lines or checker boards to have elasticity in the up, down, left and right directions of the wrinkles. It is to contribute to the convenience of users by providing rubber gloves that can prevent falling and folding.

In forming a wrinkle that can prevent the falling and folding phenomenon in the rubber gloves to be molded;

The pleats 11 formed on the upper end of the rubber gloves 10 are arranged by gathering the individual protrusions 12 and 13 such as rhombuses and cones;

The protrusions 12 and 13 protrude inwardly of the rubber gloves 10 such that the force is crushed inwardly of the rubber gloves 10 to increase adhesion;

The indentations 14 and 15 formed between the protrusions 12 and 13 may protrude to the outside of the rubber gloves 10.

Description

Wrinkle forming method of rubber gloves and its wrinkle forming mold}

The present invention relates to a wrinkle forming method of the rubber gloves and a mold for forming wrinkles, and more particularly, to improve the wrinkles formed for the purpose of preventing slipping and falling on the inlet side formed at the upper end of the rubber gloves, and easily flowing down. It is to provide a rubber glove that is prevented.

Rubber gloves are generally used in various types such as medical, home and industrial, and most of them are used to prevent the hands or hands from being damaged or contaminated by preventing water or chemicals from directly touching the users' hands. Used as

These rubber gloves are immersed in a mold in a dipping tank containing a solvent made of natural rubber to allow the solvent to adhere to the mold to a certain thickness. The rubber gloves are taken out and separated from the mold and the molding after a post process such as drying and coloring. The rubber gloves are completed by flipping.

The cuff portion of the rubber glove completed as described above is provided with elasticity when worn to enable easy wearing, and wrinkles are formed as a means for preventing it from flowing down after wearing.

Conventional wrinkles formed as described above are shown in Figures 6,7;

The unevenness (2, 3) is formed in the circumferential direction of the mold (1) on the upper end of the mold (1) for molding rubber gloves, and is formed to have a predetermined length in the longitudinal direction of the mold (1).

As can be seen from the cross-section, the unevennesses 2 and 3 formed in the mold 1 have a smooth arc shape, and the shape appearing on the rubber gloves after completion of molding is a straight wrinkle.

The rubber gloves completed as described above have the advantage that the rubber gloves can be easily inserted by the wrinkles formed by the irregularities of the mold when the rubber gloves are to be worn. It has the disadvantage of easily flowing down.

This is because the wrinkles are formed in the longitudinal direction of the rubber gloves and the unevenness is formed in an arc shape in the circumferential direction, so that the wrinkles easily flow down as the wrinkles are stretched in the arc direction.

In particular, when dipping the rubber gloves, the final product is not molded, but the inverted state becomes the final product, so that irregularities are formed in the opposite direction to the shape of the mold so that the force of the uneven portion is not applied to the inner side of the rubber gloves. It is also because.

Therefore, in the present invention, as invented to solve the problems as described above, without gathering the wrinkles formed on the rubber gloves in the longitudinal direction of the rubber gloves, gathering uneven protrusions in the form of oblique lines in the form of oblique lines or checkerboard, the image of the wrinkles, It aims to contribute to the user's convenience by providing rubber gloves that can be prevented from falling down and folding by having elasticity in the bottom, left and right directions.

In the present invention, to provide a rubber glove (10) formed with wrinkles to prevent the phenomenon of flowing down when the rubber gloves to be molded dipping and the phenomenon that the flowed portion is folded.

To this end, the corrugated portions 11 formed to prevent the rubber gloves 10 from flowing down are collected by arranging single protrusions 12 and 13, such as rhombuses or cones, in a diagonal grid or a square grid. do.

Of course, the protrusions 12 and 13 may protrude in the inward direction of the rubber gloves 10 so that the force of the protrusions 12 and 13 is crushed in the inward direction of the rubber gloves 10 to increase adhesion. Make sure that spillage is prevented.

Preferably, the indents 14 and 15 formed between the protrusions 12 and 13 may protrude to the outside of the rubber gloves 10 opposite to the protrusions 12 and 13, and the protrusions 12 and 13. ) And the degree of protrusion of the recesses 14 and 15 are more protruded than the inner and outer surfaces 16 of the rubber glove 10.

Mold 20 for molding the rubber gloves 10 for this purpose;

A wrinkle forming portion 22 is formed at the upper end of the main body 21 provided in the same shape as the rubber gloves 10.

The wrinkles forming part 22 protrudes the protrusions 23 and 24 for forming the protrusions 12 and 13 to the outside of the mold 20, and the recesses 25 and the grooves for forming the recesses 14 and 15. 26 is entered into the inward direction of the mold (20).

The protrusions 23 and 24 and the grooves 25 and 26 protrude further and enter more than the surface 27 with respect to the surface 27 of the mold 20 so as to form the protrusions 12 and 13 when forming the rubber gloves 10. ) And the recesses 14 and 15 are projected and enter the surface 16 of the rubber glove 10.

The present invention as described above;

The mold 20 is immersed in a dipping tank containing a solvent made of natural rubber so that the solvent is welded to the mold 20 to a certain thickness, and withdrawn after the post process such as a drying process or a coloring process. The rubber gloves 10, which have been adhered to the surface 27 of 20), are detached and completed.

The protrusions 12 and 13 and the concave portions 14 and 15 of the pleats 11 of the rubber gloves 10 completed as described above have the rubber gloves 10 as opposed to the molds 20. ), And the recessed portions 14 and 15 are protruded to the outside of the rubber gloves 10.

When wearing the rubber glove 10 as described above, because the projections 12 and 13 and the concave portions 14 and 15 of the pleats 11 are elastic in the up, down and left and right directions. It will not cause inconvenience to wear.

Then, after wearing, the protrusions 912 and 13 are pressed against the inner side of the rubber glove 10 to act, and thus have the same effect as wearing a band having excellent elasticity in the entire wrinkle portion 911). .

Therefore, the phenomenon in which the rubber gloves 10 easily flow down from the arm portion of the wearer is eliminated, and the phenomenon in which the rubber gloves are folded by the prevention of the fall phenomenon can be naturally solved.

In the present invention as described above, the wrinkles formed on the rubber gloves are not formed in the longitudinal direction of the rubber gloves, and the uneven protrusions of the single protrusion shape are collected in an oblique form or a checkerboard shape to have elasticity in the up, down, left and right directions of the wrinkles. By providing a rubber glove that can be prevented from falling down and folding phenomenon can contribute to the improvement of users' convenience, and can have many effects.
