Description

The present invention relates to a cord ball string which is formed by winding a string in a ball shape so that a cavity having both ends opened along a central axis, and is attached to a string ball to be used by pulling out the end of the string from the central cavity. about the pressing portion with the elastic sheet piece.

A string used for packing is wound in a ball shape so that a cavity is formed along the central axis. When used, the string is pulled out from the inside to be cut to prevent the string ball from rolling. It is common.
However, the end of the string after cutting is easy to return to the center cavity of the string ball, the string gets tangled, it is difficult to know where the tip is, and it is difficult to pull out the string when using it next time, and inconvenience is felt There were also many.

In view of this, various devices have been proposed that prevent the leading end of the string that has been removed from returning to the central cavity of the string ball.
For example, in Patent Document 1, the upper part for storing the strings is composed of an opening plate container body and a lid body that closes the upper opening part of the container body, and a rotating mouth portion having a sampling hole is provided at the center of the lid body. There is described a packing string case provided with a stopper for stopping the ends of the strings on the upper surface of the lid.
Further, Patent Document 2 includes a lower case that houses a ball wound with a tape string, and an upper case that has a hole through which the tip of the tape string passes and is screwed to the lower case. A tape string case is described in which a pin for holding the tape string at the time of cutting is mounted on the upper surface.
However, since all of the above conventional cases require a special case, the structure is complicated and expensive, and in order to prevent the tip of the string from returning to the inside of the string ball after cutting, both a stopper or I had to hang it on a pin and stop it.

The problem to be solved by the present invention is to prevent the leading end of the string from returning into the cavity formed in the center of the string ball, the structure is simple, and an operation to stop the leading end of the string every time it is used is required. An object of the present invention is to provide an elastic sheet piece with a string retainer for string balls.

The present invention is formed by winding a string in a ball shape, a cavity having both ends opened is formed along a central axis, and an end of the string is formed on the outer surface of the string ball positioned inside the cavity. the respect attached that with the cord holding portion elastic sheet piece so as to protrude to the end, to one end of one surface of the elastic sheet piece, the adhesive portion for attaching the string ball is formed on the elastic sheet piece, A string presser that can be swung with a linear cut is formed around the periphery excluding one end .
The elastic sheet may be transparent.
When the end of the string taken out from the cavity is inserted into the hole of the elastic sheet formed by forming the string pressing part, when pulling out the string, the string pressing part swings outward to pass the string, When the applied pulling force disappears, the string presser is closed and the string is sandwiched between the hole and the periphery.

According to the first aspect of the present invention, at the beginning of using the string, the end of the string is cut only by passing the end of the string taken out from the cavity through the hole of the elastic sheet piece, and then the leading end of the string. Is automatically sandwiched between the string presser and the periphery of the hole, so that the tip of the string can be reliably prevented from returning into the cavity without any special operation, and as a result, the string can be prevented from getting tangled. Thus, the string can be used up efficiently, and the string can be easily pulled out for the next use.
In addition, since it is a simple structure that simply attaches an elastic sheet piece with a string retainer to a string ball similar to a commercially available product, the price is low, and the size of the elastic sheet piece and the string retainer is simply changed. Can easily handle differences in string thickness.
According to the invention which concerns on Claim 2, even if it does not raise an elastic sheet piece, the residual amount of a string can be confirmed with eyes.

The top view of the elastic sheet piece with the string clamp part for string balls which shows the Example of this invention. Sectional drawing of the elastic sheet piece with the string presser part for string balls which shows the Example of this invention, and a string. The top view which shows the other embodiment of the elastic sheet piece with a string presser part for string balls . The top view which shows other embodiment of the elastic sheet piece with the string presser part for string balls .

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, a string ball 1 is formed by winding a string 2 used for packing, paper packaging, etc. in a ball shape.
The string 2 may be a tape string made of polypropylene or the like, or a thin hemp string having a substantially circular cross section.
The string 2 is wound so that a cavity 3 having both ends opened along the central axis of the string ball 1 is formed, and the end of the string 2 is positioned inside the cavity 3 before use.

The outer surface of the string ball 1 is covered with a transparent film 4, and the film 4 is opened at a position that coincides with both ends of the cavity 3.
Accordingly, the end of the cord 2 can be taken out from the open end of the cavity 3 and used while the cord 2 is pulled out from the inside of the cord ball 1 so that the cord ball 1 does not roll.
The above structure is not different from general commercial products.

On the outer surface of the string ball 1 (the outer surface of the film 4), an elastic sheet piece 5 is attached to an end surface surrounding the open end of the cavity 3 so as to protrude from the end of the cavity 3.
The elastic sheet piece 5 is made of a strip-shaped transparent plastic sheet having appropriate elasticity, and a linear cut is made around the one end except for one end, as shown in FIG. Is formed. That is, the string presser 6 is connected to the elastic sheet 5 so as to be swingable through one end without a break .
In this embodiment, a substantially triangular string presser portion 6 whose bottom is connected to the elastic sheet piece 5 is formed.
Further, an adhesive part 7 is formed on one end of one surface of the elastic sheet piece 5 by applying an adhesive or by sticking a double-sided adhesive tape, and the elastic sheet piece 5 is stringed through the adhesive part 7. It is attached to the ball 1.

When using the string 2, at the beginning of use, the end of the string 2 located inside the cavity 3 was formed by forming the string pressing part 6 of the elastic sheet piece 5 as shown in FIG. It is taken out from the string ball 1 through the hole 8.
When the string 2 is pulled out from the cavity 3 through the hole 8, a force for causing the string pressing portion 6 is applied, and the string pressing portion 6 swings outward to pass the string 2.
If the string 2 is pulled out by the required length and then the string 2 is cut outside the elastic sheet piece 5, the force that causes the string pressing portion 6 disappears, so that the string pressing portion 6 tries to return to the original position. And the tip of the cord 2 is sandwiched between the cord pressing portion 6 and the periphery of the hole 8 to prevent the tip of the cord 2 from returning into the cavity 3.

The string presser 6 is not limited to the shape shown in FIG. For example, as shown in FIG. 4, you may form the substantially square string press part 6 which cut | disconnected the circumference | surroundings except one side. Alternatively, as shown in FIG. 5, a string presser portion 6 having a shape in which a substantially circular large-diameter portion is integrally formed at the top of a triangle may be used.
Further, the elastic sheet piece 5 can be made opaque, but if a transparent material is used as in the above embodiment, the inside of the cavity 3 can be seen through the elastic sheet piece 5 and the remaining amount of the string 2 can be confirmed. It's easy to do.
Furthermore, the dimensions and rigidity of the elastic sheet piece 5, the size of the string pressing portion 6, and the like can be appropriately changed according to the thickness of the string 2 .
