Description

Technical Field

[0001] The utility model relates to the field of cosmetics, in particular to a pressing type cosmetic container. Background Art

[0002] With the improvement of people's living standards, cosmetics have gradually become an indispensable item in people's daily lives, and the containers for holding cosmetics have also been widely used. Pressing type cosmetic containers have been widely used due to their advantages of convenience, speed, and less residue.

[0003] At present, the Chinese utility model patent application with the publication number of CN107224092A discloses a cosmetic container, which is of a pressing type. A piston is arranged inside the outer shell of the cosmetic container. The piston is lifted to a cosmetic applicator by an engine that moves the piston only in one direction by repeatedly pressing a button. The engine is formed by a connection structure of a button, a connecting piece, an actuator, and a transmission rod. The button is exposed to the outside of the outer shell. As for the connecting piece, the button is elastically supported by a spring and moves up and down inside the shell. The actuator is connected to the connecting piece and rotates when the connecting piece moves up and down. The transmission rod is threadedly engaged with the inner diameter side of the actuator and is connected to one side of the piston in a freely rotatable manner. When the connecting piece moves up and down under the pressure of the button, the actuator rotates only in one direction, so that the transmission rod descends.

[0004] A cosmetic container disclosed in the existing patent can realize the piston rising by repeatedly pressing the button, and then forcing the cosmetics at the piston to be discharged from the container. However, the movement of the piston achieved by pressing is realized by a threaded structure to move the transmission rod and then drive the piston to move, which has the problems of many components and inconvenience in production and assembly. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a pressing type cosmetic container, which has the advantages of fewer components and convenience in production and assembly.

[0006] To achieve the above purpose and other related purposes, the utility model provides the following technical solution: A pressing type cosmetic container, comprising a shell, a storage piston built in the shell and in direct contact with cosmetics, and a button located at the end of the shell. A valve is arranged at one end of the button built in the shell. The pressing type cosmetic container further comprises:

[0007] A feeding piston built into the housing, a pressure stabilizing port is provided on the feeding piston to communicate the cavities on both sides of the feeding piston. When the button is pressed, the valve moves to block the pressure stabilizing port, thereby forming an airtight cavity between the storage piston and the feeding piston. When the button is continuously pressed to drive the feeding piston to move, the air in the airtight cavity is used to push the storage piston to move;

[0008] A first elastic member for driving the valve to disengage from the pressure stabilizing port when the button is not pressed; and,

[0009] A second elastic member for driving the feeding piston to retract to the initial position when the button is not pressed.

[0010] Through the above technical solution, in the initial state, the valve is disengaged from the pressure stabilizing port under the action of the first elastic member. When the cosmetic needs to be used, the button is pressed. The first elastic member is compressed, and the button drives the valve to move relative to the feeding piston to block the pressure stabilizing port. Then, when the button is continuously pressed, the feeding piston rises, and under the action of the air in the airtight cavity, the storage piston is pushed to rise, thereby driving the cosmetic to move. Pressing the button once pushes the storage piston to move a part. After one press is completed, the valve will disengage from the pressure stabilizing port under the action of the first elastic member. At this time, the sealed cavity disappears, and the movement of the feeding piston will not affect the storage piston. Under the action of the first elastic member and the second elastic member respectively, the button and the feeding piston retract to their original positions. Repeating the above process when pressing the button next time can further lift the storage piston. This solution uses gas to push, has a simple structure, and is convenient for production and assembly.

[0011] In an embodiment of the present invention, a partition is fixed in the housing, and a through hole for communicating the chambers on both sides of the partition is provided on the partition. The storage piston is separately arranged on one side of the partition.

[0012] Through the above technical solution, the storage piston is separated from the rest of the structures in the housing, so that the storage piston can only be pushed by gas to move and interference is excluded.

[0013] In an embodiment of the present invention, the first elastic member is arranged as a first spring, and both ends of the first spring are respectively abutted against the partition and the valve.

[0014] Through the above technical solution, when the valve is pushed by force, the first spring is compressed. When the button is not stressed, the first spring exerts a force on the valve to make it return to its original position.

[0015] In an embodiment of the present invention, the second elastic member is arranged as a second spring, and both ends of the second spring are respectively abutted against the partition and the feeding piston.

[0016] Through the above technical solution, when the button pushes the feeding piston to lift, the second spring is compressed, and when the button is not stressed, the second spring applies a force to the feeding piston to make it return to its original position.

[0017] In an embodiment of the present invention, the feeding piston includes a sealing ring in contact with the inner wall of the housing and a sealing sleeve fixed in the middle of the sealing ring. The air valve is inserted into the sealing sleeve, and the pressure stabilizing port is opened at the end of the sealing sleeve.

[0018] Through the above technical solution, the sealing sleeve restricts the air valve in the middle, so that the sealing sleeve plays a guiding role in the movement of the air valve, enhancing the stability of the air valve when pressed and moved.

[0019] In an embodiment of the present invention, a cover body is buckled at one end of the housing away from the button, and one end of the cover body away from the housing is spaced from the opening of the housing.

[0020] Through the above technical solution, the cosmetic cannot retract after extending out of the housing, and the cover body protects the cosmetic while leaving a space for accommodating the cosmetic.

[0021] As described above, the push-button cosmetic container of the present invention has the following beneficial effects:

[0022] In the initial state, the air valve is in a disengaged state from the pressure stabilizing port under the action of the first elastic member. When the cosmetic needs to be used, the button is pressed, the first elastic member is compressed, the button drives the air valve to move relative to the feeding piston to block the pressure stabilizing port. Then, when the button is continuously pressed, the feeding piston rises, and under the action of the air in the airtight cavity, the storage piston is pushed to rise, thereby pushing the cosmetic to move. Pressing the button once pushes the storage piston to move a part. After one press is completed, the air valve will be disengaged from the pressure stabilizing port under the action of the first elastic member. At this time, the sealed cavity disappears, and the movement of the feeding piston will not affect the storage piston. Under the action of the first elastic member and the second elastic member respectively, the button and the feeding piston return to their original positions. Repeating the above process when pressing the button next time can further lift the storage piston. This solution uses gas to push, has a simple structure, and is convenient for production and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0030] Please refer to Figure 1 and Figure 2 The present invention provides a pressing type cosmetic container, including:

[0031] A housing 1, a storage piston 2 built in the housing 1 and in direct contact with the cosmetic, and a button 3 located at the end of the housing 1. One end of the housing 1 away from the button 3 is set as an opening, and the cosmetic is located on the side of the storage piston 2 close to the opening of the housing 1. An air valve 4 is provided at one end of the button 3 built in the housing 1.

[0032] Please refer to Figures 2 to 4 It further includes a feeding piston 5 built in the housing 1. The feeding piston 5 is arranged between the storage piston 2 and the air valve 4. The feeding piston 5 includes a sealing ring 10 abutted against the inner wall of the housing 1 and a sealing sleeve 11 fixed to the middle of the sealing ring 10. A pressure stabilizing port 6 communicating the two cavities on both sides of the feeding piston 5 is opened at the end of the sealing sleeve 11. The air valve 4 is inserted into the sealing sleeve 11. When the button 3 is pressed, the air valve 4 is driven to move so that the air valve 4 abuts against the feeding piston 5. At this time, the air valve 4 blocks the pressure stabilizing port 6, and thus an airtight cavity is formed between the storage piston 2 and the feeding piston 5, so as to drive the storage piston 2 to move by the air in the airtight cavity when the button 3 is continuously pressed, and then drive the cosmetic to move towards the opening side of the housing 1. At the same time, the air valve 4 is arranged in the middle of the sealing sleeve 11, so that the sealing sleeve 11 guides the movement of the air valve 4, enhancing the stability of the air valve 4 when being pressed and moving.

[0033] Please refer to Figure 2, it further includes a partition plate 9 fixed inside the housing 1. The partition plate 9 is provided with through holes for communicating the chambers on both sides of the partition plate 9. The storage piston 2 is separately arranged on one side of the partition plate 9 close to the opening of the housing 1, and the feeding piston 5 and the air valve 4 are both arranged on the other side of the partition plate 9, so that the feeding piston 5 and the air valve 4 can only drive the storage piston 2 to move by pushing gas.

[0034] Please refer to Figure 2 , it further includes a first elastic member 7 for driving the air valve 4 to disengage from the pressure stabilizing port 6 when the button 3 is not pressed. The first elastic member 7 is set as a first spring, and both ends of the first spring are respectively abutted against the partition plate 9 and the air valve 4. When the air valve 4 is pushed by force, the first spring is compressed. When the button 3 is not stressed, the first spring applies a force to the air valve 4 to make it return to its original position.

[0035] Please refer to Figure 2 , it further includes a second elastic member 8 for driving the feeding piston 5 to retreat to the initial position when the button 3 is not pressed. The second elastic member 8 is set as a second spring, and both ends of the second spring are respectively abutted against the partition plate 9 and the feeding piston 5. When the button 3 pushes the feeding piston 5 to lift, the second spring is compressed. When the button 3 is not stressed, the second spring applies a force to the feeding piston 5 to make it return to its original position.

[0036] Please refer to Figure 2 , a cover 12 is buckled at one end of the housing 1 away from the button 3. The cover 12 plays a protective role for the cosmetics, and one end of the cover 12 away from the housing 1 is spaced from the opening of the housing 1, so that a space for accommodating the part of the cosmetics that extends out of the housing 1 and cannot retreat is left between the cover 12 and the opening of the housing 1.

[0037] In the initial state of the present utility model, the air valve 4 is in a disengaged state from the pressure stabilizing port 6 under the action of the first elastic member 7. When the cosmetics need to be used, the button 3 is pressed. The first elastic member 7 is compressed, and the button 3 drives the air valve 4 to move relative to the feeding piston 5 to block the pressure stabilizing port 6. Then, the button 3 is continuously pressed, and the feeding piston 5 rises. Under the action of the air in the airtight cavity, the storage piston 2 is pushed to rise, and then the cosmetics are pushed to move. Pressing the button 3 once pushes the storage piston 2 to move a part. After one press ends, the air valve 4 will disengage from the pressure stabilizing port 6 under the action of the first elastic member 7. At this time, the sealed cavity disappears, and the movement of the feeding piston 5 will not affect the storage piston 2. The button 3 and the feeding piston 5 return to their original positions under the action of the first elastic member 7 and the second elastic member 8 respectively. Repeating the above process when pressing the button 3 next time can further lift the storage piston 2. This solution uses gas to push, has a simple structure, and is convenient for production and assembly.

[0038] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not intended to limit the present utility model. All equivalent modifications or changes made by those with ordinary knowledge in the technical field to which the present utility model pertains without departing from the spirit and technical concept disclosed by the present utility model should still be covered by the claims of the present utility model.
