In the present invention, a bottle cap including a cylindrical wall portion having a spiral screw structure formed therein, and a closure portion formed integrally with the wall portion to seal an upper end of the wall portion, wherein the inner surface of the closure portion and the spiral shape are provided. A bottle cap having an annular stopper is provided on an inner surface of the wall portion between the threaded end portions of the wall portion and spaced a predetermined distance from the inner surface of the closure portion.

Description

Bottle Cap {A Bottle Cap}

The present invention relates to a threaded bottle cap. More particularly, the present invention relates to an inner structure of a lid of a liquid container, and more particularly to a bottle cap having a gasket preventing separation of the gasket inserted into the bottle lid.

A thread is formed at the upper end of the bottleneck of the container containing the liquid, and a thread is formed at the inside of the cap of the container so as to be screwed with the thread of the bottle cap. The liquid container of such a structure is designed to open and close the bottle cap by turning it. It is also common to interpose an elastic gasket between the top of the bottleneck and the inner surface of the top of the bottle cap to maintain the closure of the liquid container in the closed state.

1A and 1B are schematic cross-sectional views of a bottle cap in which a conventional gasket is inserted. As shown in FIG. 1A, the bottle cap in which a spiral screw structure is formed therein is integral with the cylindrical wall portion 10 and the wall portion 10 in which a spiral screw structure is formed therein. It is formed of a stopper portion 40 for sealing the upper end of the wall portion 10. The spiral screw structure formed on the inner surface of the wall portion 10 is connected to the first screw thread 20 formed at the position closest to the inner surface of the stopper portion 40 and the first screw thread 20 spirally. The first screw thread 20 is formed of a second screw thread 30 which is farther from the inner surface of the upper end portion than the first screw thread 20 and a screw thread which is formed spirally from the second screw thread 30. In addition, when viewed from the cross section of the bottle cap of Figure 1, the gasket 50 is inserted between the first thread 20 and the second thread 30 and the inner surface of the cap 40.

However, the gasket 50 inserted into the conventional bottle cap has a large gap between the inner surface of the cap portion 40 and the first thread 20 and the second thread 30. There is a problem that the gasket 50 flows out of the bottle cap when the lid is manufactured. In order to solve the problem, the inner surface of the gasket 50 and the stopper 40 is fixed using an adhesive, or the thickness of the gasket 50 is thickened so that the inner surface of the stopper 40 and the screw thread. It is using a method to prevent deviation by reducing the gap of.

However, bonding the gasket 50 to the inside of the bottle cap using an adhesive as described above cannot be used when the liquid contained in the container needs to maintain pure water because the adhesive is likely to be a harmful substance. To manufacture a thick thickness of the gasket 50 is more costly, there is a problem that must be manufactured by varying the length of the bottle cap in accordance with the thickness of the gasket (50). In addition, when the thickness of the gasket is thickened, since the gasket material is mainly made of synthetic resin, it is necessary to use a lot of plasticizer components to give the gasket flexibility. However, there is a problem that it is difficult to give the gasket sufficient flexibility because the content of the plasticizer component to be delivered to the food is strictly regulated.

Therefore, even when a thin gasket is inserted into the bottle cap, it is desired to develop a bottle cap such that the gasket does not detach from the bottle cap during use or during bottle cap manufacturing.

The present invention is to solve the problems of the prior art, an object of the present invention is a bottle cap in which a spiral screw structure is formed therein, the thin gasket inserted into the inside of the bottle cap when manufacturing the bottle cap Or to provide a bottle cap of the structure that does not detach from the bottle cap in use.

As a technical solution for achieving the object of the present invention, in the present invention, a cylindrical wall portion having a spiral screw structure formed therein, and a stopper portion integrally formed with the wall portion to seal an upper end of the wall portion. In the bottle cap containing,

A bottle cap having an annular stopper is provided on the inner surface of the wall portion between the inner surface of the closure portion and the screw threaded end portion and spaced a predetermined distance from the inner surface of the closure portion.

According to the present invention, there is an effect that the gasket does not escape from the bottle cap during manufacture or use of the bottle cap into which the gasket is inserted. In addition, since a thin gasket can be used, the size of the bottle cap can be reduced, and eco-friendliness can be achieved by reducing the gasket manufacturing cost and reducing the plasticizer component.

1 is a schematic cross-sectional structural view of a conventional screw-type bottle cap with a gasket inserted.
FIG. 2 is a schematic stage configuration diagram of an embodiment of a screw bottle cap in which a thin gasket of the present invention is inserted.

Hereinafter, with reference to the accompanying drawings, the configuration of the invention according to an embodiment of the present invention will be described in detail.

2 is a schematic cross-sectional view of an embodiment of a screw-type bottle cap into which a thin gasket of the present invention is inserted. 2 a and b is a cross-sectional configuration diagram when one bottle cap is cut.

 As shown in Figure 2, the bottle cap of the present invention is formed integrally with the wall portion 10, and the wall portion 10, the wall portion 10 of the cylindrical screw structure is formed therein the spiral shape inside the wall portion 10 In the bottle cap consisting of a cap portion 40 for sealing the top of the, the spiral screw structure formed on the inner surface of the wall portion 10 is formed at a position closest to the inner surface of the cap portion 40 The second screw thread 30 and the second screw thread 30 which are spirally connected to the first screw thread 20 and the first screw thread 20 and are farther from the inner surface of the upper end than the first screw thread 20. And a screw thread extending in a spiral shape, the annular protrusion being formed between the inner surface of the stopper portion 40 and the screw end portion of the spiral portion and the inner surface of the wall portion spaced a predetermined distance from the inner surface of the stopper portion 40. It is characterized in that the stopper 100 in the form is formed As it is.

In the exemplary embodiment of the present invention, when the thin gasket 200 having a diameter smaller or corresponding to the inner diameter of the bottle cap is pushed into the bottle cap, the stopper 100 may be slightly bent due to the elasticity of the gasket 200. ) Is inserted into the inside. Since the inserted gasket 200 is inserted into the stopper 100 and restored to its own elastic shape, the diameter of the gasket 200 becomes larger than the inner diameter of the annular stopper 100, so that the stopper 100 as shown in FIG. ) Does not escape outside.

If the interval from the inner surface of the stopper 40 to the stopper 100 is such that the gasket 200 is not separated from the stopper 100 even when the thin gasket 200 is flowed in the inserted state. good. In addition, the cross-sectional shape of the protrusion of the stopper 100 may be configured in various forms as necessary without being limited to any one of a semi-circular, triangular, square, and the like.

In addition, in the above-described embodiment of the present invention, the stopper 100 has been described as an annular protrusion formed along the inner circumferential surface of the wall portion 10, but is not limited thereto. At least two or more protrusions may be formed along the inner circumferential surface of the wall portion 10 at regular intervals.
