Description

[Detailed description of the invention] This invention can pour out cosmetics by lowering the on-off valve by the action of the pressure of the body and the spring, and when the pressure is stopped, the on-off valve rises to prevent backflow of outside air. It relates to an air backless tube that has been made possible, and more specifically, it has a tube body with a base provided inside the opening via a bridge, and a tube that has a spout in the center of the ceiling and can be fitted to the neck of the tube body. a stopper, an on-off valve having a frame pillar standing in the center thereof capable of closing the spout of the inner stopper and having an outer diameter that can be moved up and down along the inner circumferential surface of the base part; the on-off valve and the base part; The present invention relates to a tube made of a combination of a spring and a spring interposed between the tube and the spring.

Conventionally, there are various air backless mechanisms for tubes,
Since cosmetics accumulate between the spout and the backless mechanism, there is a drawback that the accumulated cosmetics may oxidize or change color.

This invention prevents the cosmetic from coming into contact with air after being used, and
To provide a new air-backless tube mechanism in which cosmetics do not accumulate.

To specifically explain one embodiment of the present invention with reference to the drawings, the first embodiment is as follows.
In the figures 1 to 3, reference numeral 1 denotes a tube body, and a cylindrical base 4 is attached to the inside of the neck 2 via a bridge 3. Also, at the center of the bottom of this base 4, there is a tube body 4, which will be described later. A spring accommodating portion 5 that can accommodate a spring is configured to protrude downward.

6 is a coil spring that can be inserted into the spring storage section 5 of the base section 4.

Reference numeral 7 denotes an on-off valve that can be inserted into the platform 4 so as to be able to move up and down.The outer peripheral surface of the valve 7 is formed to have an outer diameter that allows it to come into close contact with the inner surface of the platform 4, and the central portion thereof has a conical shape. frame pillar 8
is installed in a standing position.

Reference numeral 9 denotes an inner stopper that can be fitted into the neck 2 of the main body 1, and a ring rib b that can be fitted into a ring groove a formed in the inner circumferential wall of the neck 2 protrudes from its outer periphery. A spout 10 into which the frame post 8 of the on-off valve 7 can fit is formed in the spout 10 .

In assembling the tube according to the present invention, as shown in FIGS. 2 and 3, after storing the spring 6 in the storage part 5 of the base part 4, the on-off valve 7 is inserted into the base part 4, Furthermore, inner stopper 9
It can be assembled by fitting the ring rib b into the ring groove a formed in the inner circumferential wall of the neck portion 2 of the main body 1.

In use, by pressing the tube body 1, the internal pressure lowers the on-off valve 7 against the spring 6, thereby closing the gap between the inner surface of the neck 2 of the cosmetic G in the main body 1 and the outer surface of the base 4. After passing through the spout 10 along the circumference of the frame pillar 8
It is possible to pour out more.

When the pressure on the tube body 1 is stopped, the on-off valve 7 is pushed up by the action of the spring 6, and the spout 10 is immediately closed by the frame post 8, preventing outside air from flowing back into the tube body.

As mentioned above, in the tube according to the present invention, the container is attached to the neck via the bridge, and the on-off valve is housed in the stand so that it can be raised and lowered by the spring. can be freely lowered to pour out the cosmetics in the tube, and when the pressure is stopped, the on-off valve will rise to completely seal the injection port and prevent outside air from flowing back into the tube. Therefore, there is no risk that the remaining cosmetics in the tube will be exposed to outside air and deteriorate in quality, and it also has features such as preventing the contents from scattering due to outside air being mixed in during use.
