Description

Technical Field

[0001] The utility model belongs to the technical field of droppers, and particularly relates to a spin-on dropper cap with a piston made of a heat-shrinkable elastomer TPE material. Background Art

[0002] The piston moves up and down or left and right within the stroke range of the pump valve cavity. When the piston moves downward or to the right, it expels air, and when the piston moves upward or to the left, it inhales liquid. This is the technical application of the piston in the pump valve. The piston is a very important precision functional component. Its material and dimensional precision, including the matching with the cavity size, directly affect the function of the entire product. The existing piston material is made of rubber, PE or PP.

[0003] Although rubber pistons have good air tightness and sealing properties and are relatively smooth, they may have compatibility issues with cosmetic materials. PE or PP materials have good compatibility with cosmetic materials, but as piston component materials, they are relatively hard. During the sliding process in the hard plastic cavity, they are not very smooth and cause the piston to move fast and slow in the cavity. In addition, the air tightness and sealing properties of the hard material are poor, and it is easy for the size to be larger when matching with the cavity size. This will result in a tight match, resulting in a heavy feel when pushing and pulling the piston, and causing the liquid to be not smooth and uneven. The problems with the above technology are: poor air tightness and sealing, and non-smooth and uneven liquid discharge. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model provides a spin-on dropper cap with a piston made of a heat-shrinkable elastomer TPE material, which can overcome the above problems or at least partially solve the above problems.

Through the dropper clamp, the bottom of the dropper clamp is sealed and connected to the top of the glass dropper to control the entry and exit range of the material.

[0009] In order to increase the connection effect with the bottle, preferably, an inner cover clamp is installed at the bottom of the cavity, and the bottom of the glass dropper passes through the inner cover and the inner cover clamp in sequence and extends to the bottom of the outer cover.

[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 7As shown, the embodiment of the utility model provides a spin-on dropper cap with a piston made of a heat-shrinkable elastomer TPE material, including a protection component 1 and a pressing component 2 constituting the spin-on dropper cap, the protection component 1 including an outer cover 1a and a cavity 1b, the cavity 1b is opened inside the outer cover 1a, the pressing component 2 is located inside the cavity 1b, the pressing component 2 includes a pressing cap 2a, an inner cover 2b, a piston 2c, a spring 2d and a glass dropper 2e, the inner cover 2b is installed at the bottom of the cavity 1b, the surface of the pressing cap 2a is movably connected to the top of the cavity 1b, the bottom of the pressing cap 2a is movably connected to the top of the inner cover 2b, and the piston 2c It is installed at the bottom of the inside of the pressing cap 2a, the surface of the piston 2c is slidably connected with the top of the inner cover 2b, the spring 2d is sleeved on the surface of the inner cover 2b, the side of the spring 2d close to the inner cover 2b is fixedly connected with the inner cover 2b, the top of the spring 2d is fixedly connected with the top of the inside of the pressing cap 2a, and the glass dropper 2e is located inside the inner cover 2b; the protection component 1 is used to support and protect the pressing component 2; the pressing component 2 is used to absorb the material body, and in order to make the material body enter and exit the effect better, a dropper clamp 3 is installed on the top of the inside of the glass dropper 2e, the surface of the dropper clamp 3 is in contact with the inside of the inner cover 2b, and the bottom of the dropper clamp 3 is passed through the dropper clamp 3. The top of the glass dropper 2e is sealed and connected to control the range of material in and out. In order to increase the connection effect with the bottle, an inner cover collar 4 is installed at the bottom of the cavity 1b. The bottom of the glass dropper 2e passes through the inner cover 2b and the inner cover collar 4 in sequence and extends to the bottom of the outer cover 1a. Through the inner cover collar 4, the top of the bottle can be movably connected with the inner cover collar 4, so that the top of the bottle and the bottom of the outer cover 1a are more closely connected, thereby sealing. In order to fix or open the push cap 2a with the outer cover 1a, a card slot 5 used in conjunction with the outer cover 1a is opened on the surface of the push cap 2a. The push cap 2a is rotated to make the buckle of the outer cover 1a 6 is released from the card slot 5 of the push cap 2a. The push cap 2a moves upward under the action of the spring 2d. By applying the heat-shrinkable elastomer TPE polymer material to the piston 2c, that is, the piston 2c material is TPE. TPE has excellent chemical stability, and is particularly good in anti-aging and oil resistance. TPE is a heat-shrinkable elastic feature with softness, toughness and wear resistance. The use of TPE as a piston 2c greatly improves the functionality of pump and valve products, such as making the hand feel smoother and softer, and enhancing air tightness and sealing. The application of TPE piston 2c in pumps and valves makes the product quality superior and the experience better.

[0024] The working principle of the utility model is as follows: when in use, the dropper cover is screwed into the bottle mouth, the outer cover 1a drives the buckle 6 to rotate clockwise, and the press cap 2a moves downward through the height difference of the card slot 5 in the press cap 2a, and the press cap 2a drives the piston 2c to move downward to discharge the air in the glass dropper 2e, and the dropper cover is tightened and sealed with the bottle, and the spring 2d is deformed during the downward movement of the press cap 2a. When using makeup, the dropper cover is unscrewed, the buckle 6 of the outer cover 1a is loosened from the card slot 5 of the press cap 2a, and the press cap 2a moves upward and rebounds under the elastic action of the spring 2d, so that the press cap 2a drives the piston 2c to move upward, thereby sucking the material.
