Description

Technical Field

[0001] The utility model relates to a cosmetic bottle, in particular to a cosmetic bottle that discharges liquid as soon as the cap is opened. Background Art

[0002] With the development of technology and the progress of life, the usage rate of various high-grade cosmetics has been increasing. Fluid cosmetics include oil, lotion, cream, etc. For fluid cosmetics, in addition to conventional bottles, cosmetic bottles generally use pressing bottles, which are more convenient to use.

[0003] For a pressing bottle, when a user uses it, first the outer cap needs to be opened, and then the inner cap of the bottle needs to be pressed downwards so that the medium in the bottle can flow out. The user needs to perform two-step operations: 1. Open the outer cap; 2. Press the inner cap of the bottle. In addition, it is difficult to control the extrusion amount of the pressing bottle. When the force is too large, too much content is extruded. Usually, the user will suck the excessive content back into the bottle, which is likely to cause content pollution. When the extrusion force is too large, the content will also splash, resulting in a large amount of content waste and inconvenient use.

[0004] Therefore, it is expected to provide a cosmetic bottle that discharges liquid as soon as the cap is opened to solve the above technical problems. Content of the Utility Model

[0047] As Figure 2 shown in the figure, the cap assembly 2 includes a lower cap 3, a moving body, and an outer cap 4; the lower cap 3 is detachably fixed at the top outlet of the bottle body 1. In this embodiment, the lower cap 3 is threadedly connected to the top outlet of the bottle body 2.

[0048] A cavity 5 is provided inside the lower cap 3, the top of the cavity 5 is located at the top inner wall of the lower cap 3, and the cavity 5 shares the same axis with the lower cap 3; a first one-way valve 6 is provided at the middle position of the bottom of the cavity 5. When the first one-way valve 6 is opened, the medium in the bottle body 1 flows into the cavity 5 unidirectionally.

[0049] The moving body includes a piston rod 7 and a spring 8; the piston rod 7 is vertically slidably inserted on the lower cap 3, and the bottom of the piston rod 7 is always located inside the cavity 5; a piston sheet 9 is vertically slidably arranged inside the cavity 5, the piston sheet 9 is inserted on the piston rod 7, and the piston rod 7 divides the cavity 5 into an upper cavity 10 and a lower cavity 11, and the upper cavity 10 is located above the lower cavity 11; a second one-way valve 12 is provided on the piston sheet 9. When the second one-way valve 12 is opened, the medium in the lower cavity 11 flows into the upper cavity 10 unidirectionally.

[0050] A flow channel 13 is provided inside the piston rod 7, the flow channel 13 penetrates through the top of the piston rod 7, and the flow channel 13 is communicated with the upper cavity 10.

[0051] The spring 8 is sleeved on the upper part of the piston rod 7; and the bottom of the spring 8 is in contact with the top of the lower cap 3, and the top of the spring 8 is in contact with the upper part of the piston rod 7.

[0052] In this embodiment, an upper cap 14 is vertically slidably inserted on the lower cap 3, the piston rod 7 is fixedly connected to the upper cap 14, and the top of the piston rod 7 extends out of the top of the upper cap 14; arranged in this way, it plays a certain protective role for the spring 8 and the piston rod 7.

[0053] The outer cap 4 is covered on the lower cap 3 by an insertion method. In this embodiment, magnets (not shown in the figure) are provided at the parts where the lower cap 3 and the outer cap 4 are in contact, which can effectively improve the stability of the outer cap 4 covered on the lower cap 3.

[0054] As Figure 3As shown, before the above cosmetic bottle leaves the factory, the piston rod 7 is pressed once, and then the outer cover 4 is closed, so that the cosmetic medium flows into both the upper cavity 10 and the lower cavity 11. When in use, the staff removes the outer cover 4, and the piston rod 7 moves upward under the action of the elastic force of the spring 8, thereby driving the piston piece 9 to move upward. The space of the lower cavity 11 becomes larger and the internal pressure becomes smaller. The cosmetic medium in the bottle body 1 flows into the lower cavity 11 through the first one-way valve 6. The space of the upper cavity 10 becomes smaller and the internal pressure becomes larger. The cosmetic medium in the upper cavity 10 will flow upward along the flow channel 13 in the piston rod 7 and flow out for the user to use. The user does not need to press again, achieving the purpose of discharging liquid when the cap is opened.

[0055] In this embodiment, as Figure 4 and Figure 5 shown, a through hole 15 is provided at the central part of the piston piece 9. The through hole 15 is sequentially divided into a first tapered hole 16, a cylindrical hole 17, and a second tapered hole 18 from top to bottom. The aperture of the first tapered hole 16 gradually decreases from top to bottom, and the aperture of the second tapered hole 18 gradually increases from top to bottom. As Figure 6 and Figure 7 shown, the bottom of the piston rod 7 has an adapter block 19. The adapter block 19 is sequentially divided into a first tapered block 20, a cylindrical block 21, and a second tapered block 22 from top to bottom. The outer diameter of the first tapered block 20 gradually decreases from top to bottom and is adapted to the first tapered hole 16. The cylindrical block 21 is adapted to the cylindrical hole 17. The outer diameter of the second tapered block 22 gradually increases from top to bottom and is adapted to the second tapered hole 18. A plurality of channel holes 23 are uniformly provided obliquely downward on the first tapered block 20 on the piston rod 7. The channel holes 23 are communicated with the flow channel 13 and penetrate through the outer wall of the first tapered block 20. With such a setting, when the outer cover 4 is closed, the spring 8 in the moving body is compressed, and the piston rod 7 moves downward until the outer wall of the first tapered block 20 fits against the outer wall of the first tapered hole 16. At this time, the channel holes 23 are completely blocked, and the piston piece 9 is driven to move downward, and the air in the lower cavity 11 is compressed, and the cosmetic medium in the lower cavity 11 flows into the upper cavity 10. When the outer cover 4 is opened, the elastic force of the spring 8 causes the piston rod 7 to move upward, the first tapered block 20 gradually disengages from the first tapered hole 16, the channel holes 23 are communicated with the upper cavity 10, the second tapered block 22 fits against the second tapered hole 18, driving the piston piece 9 to move upward, the upper cavity 10 is compressed, and the cosmetic medium in the upper cavity 10 flows into the flow channel 13 along the channel holes 23 and finally flows out from the top of the piston rod 7 for the user to use.

[0056] Furthermore, as Figure 8As shown, an air supplement through-hole 24 is provided on the side wall of the cavity 5. The position of the air supplement through-hole 24 on the cavity 5 is such that when the piston rod 7 moves upward and the piston piece 9 does not move, the air supplement through-hole 24 communicates with the upper cavity 10. With this arrangement, when the piston rod 7 moves upward and the piston piece 9 does not move, external air enters the upper cavity 10 through the flow channel 13 and flows into the bottle body 1 through the air supplement through-hole 24 to supplement the atmospheric pressure, facilitating subsequent use.

[0057] In this embodiment, as Figure 3 shown, a pipe 25 is vertically provided at the central position of the bottom of the cavity 5. The pipe 25 extends straight to the bottom of the bottle body 1 and has a gap with the bottom of the bottle body 1 to facilitate the full use of the cosmetic medium in the bottle body.
