Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 and 2, the cosmetic container of this embodiment includes a body 1, a head cap 2, a valve seat 3, a check valve 4 and an elastic extension tube 5, wherein the body 1 is a sleeve structure with a closed lower end, a liquid outlet 11 is formed in a bottom wall of the sleeve structure, the head cap 2 can be vertically moved and disposed on the top of the body 1 and has an emulsion outlet 21, the valve seat 3 is disposed in the head cap 2 and has a passage 31 communicated with the emulsion outlet 21, the check valve 4 is disposed in the head cap 2 and is sealed with the passage 31 in a matching manner, the upper end of the elastic extension tube 5 is sleeved on the periphery of the valve seat 3, and the lower end of the elastic extension tube abuts against the periphery of. The above structures and the assembling relationship therebetween are prior art and will not be described herein.

The elastic telescopic tube 5 of the present embodiment is provided with a base 6 disposed near the bottom, the base 6 has a first liquid guiding portion 61 penetrating up and down, a second liquid guiding portion 71 capable of communicating with the first liquid guiding portion 61 is disposed below the channel 31 of the valve seat 3, the lower end of the second liquid guiding portion 71 is a blind end and is inserted into the first liquid guiding portion 61, the second liquid guiding portion 71 is provided with a liquid guiding hole 711 on the outer peripheral wall near the lower end, the first liquid guiding portion 61 can communicate with the second liquid guiding portion 71 after moving downward relative to the first liquid guiding portion 61, and the second liquid guiding portion 71 can be matched with the inner wall of the first liquid guiding portion 61 to block the first liquid guiding portion 61 from the second liquid guiding portion 71 after moving upward relative to the first liquid guiding portion 61.

Specifically, the inner diameter of the lower part of the base 6 is larger than that of the upper part, and the lower part of the base 6 is surrounded on the periphery of the liquid outlet 11 of the body 1. This structure facilitates communication between the first liquid guide portion 61 and the second liquid guide portion 71 in the state where the head cap 2 is pressed, and improves the sealing property. The middle part of the lower port of the elastic telescopic pipe 5 is provided with a valve plate 51 which can cover the liquid outlet 11 of the body 1, and the lower edge of the elastic telescopic pipe 5 extends towards the middle part of the lower port and is connected with the valve plate 51 through an elastic strip 52. The provision of the valve sheet 51 can further improve the sealability of the cosmetic container.

In this embodiment, the cosmetic container further includes a guide sleeve 7, an upper end of the guide sleeve 7 is fitted around the periphery of the channel 31 of the valve seat 3, a lower portion of the guide sleeve 7 forms the second liquid guiding portion 71, and an upper port of the second liquid guiding portion 71 is engaged with a lower port of the channel 31. The guide sleeve 7 is provided primarily for ease of manufacture and assembly, but in practice the guide sleeve 7 may be formed as an integral structure with the valve seat 3 if technology permits. The lower end of the second liquid guiding portion 71 is inserted into the upper port of the first liquid guiding portion 61 in a vertically movable manner, and in a natural rebounding state of the elastic telescopic tube 5, the inner wall of the first liquid guiding portion 61 closes the liquid guiding hole 711 on the second liquid guiding portion 71, and in a compressed state of the elastic telescopic tube 5, the liquid guiding hole 711 on the second liquid guiding portion 71 is exposed in the lower cavity of the first liquid guiding portion 61, so that the liquid in the base 6 goes upward through the second liquid guiding portion 71.

In this embodiment, a cap ring 8 is sleeved on the periphery of the body 1, and the body 1 is screwed to the mouth of a bottle 9 through the cap ring 8. The piston 91 capable of sliding up and down along the inner wall of the bottle body 9 in a sealing manner is arranged in the bottle body 9, and the structure is convenient for the vacuum bottle structure, so that the sealing effect is improved.

During the use, press head cap 2, drive check valve 4, disk seat 3, uide bushing 7 downstream together, the flexible pipe of elasticity 5 receives the effect of downward force, takes place deformation, at this moment, the air in the flexible pipe of elasticity 5 constantly compresses, and pressure increases gradually, increases to certain extent as pressure, forces the check valve to take place deformation, forms the clearance between check valve and the connecting seat this moment, and first drain portion 61 is inside to be linked together with second drain portion 71, and the air is got rid of from the head cap liquid outlet through the clearance. Along with the air discharge, the pressure in the elastic extension tube 5 is reduced, and the one-way valve is restored and is restored to the original state. The gap between the check valve and the valve seat disappears. When the head cap is loosened by hand, the head cap is not acted by the pressing force at the moment, and is acted by the resilience force of the elastic extension tube 5, and the head cap, the one-way valve, the valve seat and the guide sleeve move upwards together for resetting. Along with the gradual rebound of the elastic extension tube 5, the pressure in the elastic extension tube 5 is gradually reduced and forms a pressure difference with the bottle body, and at the moment, the liquid in the bottle body rushes the one-way valve at the bottom of the elastic extension tube 5 to enter the elastic extension tube 5. The head cap is pressed again by hand to drive the one-way valve, the valve seat and the guide sleeve to move downwards, and the elastic extension tube 5 is deformed under the action of the downward force. At this moment, the liquid in the elastic expansion pipe 5 is continuously compressed to form huge pressure, and finally the one-way valve is forced to deform, and the liquid passes through a gap formed between the one-way valve and the valve seat and finally flows out of the liquid outlet 11 of the head cap 1. The liquid in the bottle body is continuously discharged in such a reciprocating way, and the bottle piston continuously moves upwards along with the continuous discharge of the liquid.
