Description

Air inlet for a tube {The air inlet for a swim ring}

The present invention relates to an air inlet for a tube, and more specifically, the air inlet is a dual structure consisting of a large diameter soft discharge tube and a soft air inlet tube formed of one body in a discharge cap inserted into the discharge tube. The air inlet tube is used to inject the air, and when the air in the tube is discharged, the outlet tube is used, and at the same time, the outlet tube, the discharge cap, and the inlet plug inserted into the air inlet tube are integrally formed by one. The present invention relates to an air inlet for a tube having a double structure that prevents excessive discharge time and inconvenience, which is a problem caused by discharging air only through the air injection tube.

In general, a small tube, such as a dip tube, that blows air into the mouth, takes not only the time required to drain the air injected into the tube, but also requires that the person press the tube while keeping the inlet pressed to release the air. There is an inconvenience to look at this in detail as follows.

The conventional general water tube has a structure in which an air inlet 12 is coupled to one surface of the tube body T, and the air inlet increases in diameter toward the bottom of the lower end of the cylindrical upper tube 12A1 having a constant inner diameter. The lower pipe 12A2 is connected to the other side of the air injection pipe 12A having an extended shape and the ribbon bridge B extending to one side of the upper end of the air injection pipe 12A, and inserted into the center of the bottom surface of the disc-shaped cover plate 12B1. The projection 12B2 is constituted by the inlet stopper 12B formed upright.

The outer circumferential surface is separated from the inner circumferential surface of the lower pipe from the inner circumferential surface boundary of the upper and lower pipes whose inner diameter is increased, and the inner circumferential surface forms a space in which the insertion protrusion 12B2 enters in the hollow of the lower pipe. The cup-shaped blocking film M is provided with a straight gap C slit along one inner arc-like inner and outer circumferential surface so that two surfaces facing each other abut each other and penetrate the inner and outer circumferential surfaces.

When the insertion protrusion of the injection hole is inserted into the insertion hole (H) formed by the upper tube of the air injection tube and the blocking membrane in a state in which air is introduced into the tube using the conventional air injection port configured as described above, The upper part is in close contact with the inner circumferential surface of the upper tube, and the lower part thereof is slightly separated from the inner circumferential surface of the blocking membrane, and the injection and discharge of air are made through the gap C provided in the blocking membrane.

Therefore, when the air is injected, the air is injected while the gap is opened by pressing the lower tube of the air inlet tube with the mouth or hand, and when the air is discharged, the lower tube is manually opened until all the air is discharged. It should be pressed continuously to compress the tube body while keeping the gap open so that the air can be discharged quickly.

That is, the gap C is a means for preventing the air from being quickly released from the tube even when the inlet plug is removed from the air inlet tube. This is accompanied by the inconvenience of having to hold down the lower tube of the air inlet pipe so as to open the gap.

As a means for solving the above inconveniences, the inlet structure of a tube having a double structure is disclosed in Korean Laid-Open Model Publication No. 1999-0042139.

The structure has a screw coupled to the outer peripheral surface of the injection tube and the inner peripheral surface of the cap, the following disadvantages can be pointed out as a structure in which the air inlet is coupled to the central portion of the cap.

Because the injection tube and the cap are screwed together, the cap can be lost because the two can not be made integrally, and the material of the injection tube and the cap must have a certain degree of rigidity due to the coupling property of the screw coupling. After injecting air so that the top surface of the cap is flush with the surface of the tube, it is not convenient to temporarily inject the injector into the inside of the tube as in the conventional air inlet, which causes inconvenience to the body during use.

In addition, due to the nature of the screw coupling, the cap is not coupled with sufficient force, or even when the cap is rotated slightly in use, there is a disadvantage that the air injected into the tube is easily released.

The present invention has been devised to solve all the problems of the conventional air inlet for the tube, the air inlet is composed of a dual structure of the air inlet and the air discharge pipe for the discharge of natural air through the discharge pipe It is prevented, the unitary structure connected to each component can increase the production productivity and eliminate the possibility of loss of each component, and provides an air inlet for exhausting the air in the tube to the outside easily, conveniently and quickly. There is a purpose of the present invention.

At this time, the air inlet pipe and the inlet stopper has the same structure as the conventional air inlet of the single structure described above in the prior art, the discharge cap is formed integrally with the air inlet tube, the discharge pipe is inserted and coupled The unique structure of the present invention will have a bar, which will be described in detail as follows.

First of all, the discharge pipe has an external shape of a pipe as a whole, but has a double tube structure in which a side wall having an arc-shaped flat cross section is formed of an outer wall of a large diameter and an inner wall of a small diameter having the same axis, and the outer wall and the inner wall are connected to each other at an upper end thereof to be integrated. The lower end is in a separated state.

That is, the radial cross section of the side wall is concentric with the outer wall and the inner wall, and the axial forward cross section is fixed to the tube body at the bottom by having an inverted "U" cross-sectional shape with a certain gap formed between the outer wall and the inner wall. The lower portion of the inner wall is in a state in which the lower portion of the inner wall is flowable with respect to the outer wall extending upright from the flange inner peripheral portion.
