Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging bottle technology, and more specifically to a self-sealing valve core liquid dispensing bottle. Background Technology
[0002] Cosmetics are chemical industrial products applied to the surface of the human body (such as skin, hair, nails, lips, etc.) by means of smearing, spraying, etc., with the aim of cleaning, maintaining, beautifying or modifying the appearance. Cosmetics come in a variety of forms, including solid, liquid, emulsion, colloid, powder and other forms.
[0003] Liquid packaging bottles are containers used to store liquid cosmetics. Currently, the tilting containers on the market discharge liquid through the drain hole by tilting, and the drain hole is sealed by the cap. Once the cap separates from the bottle body, or the cap falls off, especially when carried in a bag, leakage is very likely to occur, and the sealing performance is poor. Therefore, we have proposed a self-sealing valve core dispensing bottle. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a self-sealing valve core liquid dispensing bottle to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: a self-sealing valve core dispensing bottle, comprising a bottle body, a shoulder sleeve, and a cap, wherein an inner plug is installed in the inner cavity of the shoulder sleeve, a dispensing channel is provided inside the shoulder sleeve, and a dispensing assembly is provided in the inner cavity of the dispensing channel.
[0006] The liquid dispensing assembly includes a plug and a spring. The plug and spring are made of plastic and are integrally molded. The outer surface of the plug has an annular portion that contacts the inner wall of the liquid dispensing channel. The surface of the plug and above the annular portion has a conical portion that fits against the inner wall of the plug. A spring is installed on the plug, and the bottom end of the spring extends into the inner cavity of the plug and connects to its inner wall. The annular portion and the conical portion fit against the inner wall of the liquid dispensing channel to form a sealing point.
[0007] The cover consists of an outer cover and an inner cover. The inner cover has a sealing sleeve inside, and the sealing sleeve contacts the top of the shoulder cover to form a sealing point two.
[0008] Preferably, the shoulder sleeve is connected with threads, and the inner wall of the inner cover is provided with a threaded groove corresponding to the threads. The inner cover and the shoulder sleeve are connected by the threads and the threaded groove.
[0009] Preferably, the inner cover is installed into the inner cavity of the outer cover, the outer cover has a groove on its outside, and the inner wall of the outer cover has ribs installed thereon, and the ribs are inserted into the groove cavity to fix the inner cover and the outer cover.
[0010] Preferably, the sealing sleeve has a planar design or follows the shape of the shoulder sleeve.
[0011] Preferably, the shoulder sleeve is threaded onto the bottle mouth of the bottle body.
[0012] Preferably, a gasket is fitted onto the inner stopper, and the gasket is in contact with the bottle mouth end of the bottle body.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. This utility model uses a spring to support the plug. The annular and conical parts of the plug abut against the inner wall of the liquid outlet channel to form a sealing point one. When in use, pressing the plug allows liquid to flow out. When sealing, the elasticity of the spring is used to achieve a seal, re-blocking the inner cavity of the liquid outlet channel. It is convenient to use. After the cover is installed and fixed, the inner wall of the sealing sleeve contacts and fits against the outer side of the top of the shoulder sleeve to form a sealing point two, thereby achieving a second layer of sealing. The use of sealing point two in conjunction with sealing point one achieves double sealing, which can effectively prevent liquid leakage.
[0015] 2. This utility model uses the engagement between the internal threads and screw threads of the inner cap to fit the inner cap onto the shoulder sleeve. The cap is fixed by rotating clockwise and removed by rotating counterclockwise. This can prevent the cap from accidentally detaching and accidentally touching the end of the plug, thus preventing the liquid inside the bottle from flowing out and improving the stability of the product.

[0032] The liquid dispensing assembly includes a plug 5 and a spring 4. The outer surface of the plug 5 has an annular portion 9, which contacts the inner wall of the liquid dispensing channel 14. The surface of the plug 5 and above the annular portion 9 has a conical portion 10, which fits against the inner wall of the plug 5. The bottom of the plug 5 is fixedly connected to the spring 4. The plug 5 and the spring 4 are made of plastic, and the spring 4 and the plug 5 are designed as a single unit. Because the plug 5 and the spring 4 are made of plastic, the bottle body 1, the shoulder sleeve 6, the cap and other structures are also made of plastic, thus making the entire liquid dispensing bottle all plastic, which is conducive to recycling and more environmentally friendly.
[0033] The bottom end of the spring 4 extends into the inner cavity of the inner plug 2 and connects with its inner wall. The annular part 9 and the conical part 10 fit with the inner wall of the liquid outlet channel 14 to form a sealing point 15.

[0035] The shoulder sleeve 6 is connected with a thread 11, and the inner wall of the inner cover 7 is provided with a threaded groove corresponding to the thread 11. The inner cover 7 and the shoulder sleeve 6 are connected by the thread 11 and the threaded groove.
[0036] The inner cover 7 has a groove 17 on its outside, and the outer cover 8 has a rib 12 installed on its inner wall. The rib 12 is inserted into the inner cavity of the groove 17 to fix the inner cover 7 and the outer cover 8. The rib 12 is adapted to the groove 17.
[0037] The sealing sleeve 13 is a flat design, and its inner wall contacts the top of the shoulder sleeve 6 to form a sealing point 2 16.
[0038] Example 2
[0039] Reference Figures 1 to 7 This utility model provides a self-sealing valve core dispensing bottle, including a bottle body 1, a shoulder sleeve 6, and a cap. The shoulder sleeve 6 is threaded onto the bottle mouth of the bottle body 1. An inner plug 2 is installed in the inner cavity of the shoulder sleeve 6, and a gasket 3 is fitted on the inner plug 2. The gasket 3 contacts the end of the bottle mouth of the bottle body 1. A dispensing channel 14 is provided inside the shoulder sleeve 6, and a dispensing assembly is provided in the inner cavity of the dispensing channel 14.
[0040] The liquid dispensing assembly includes a plug 5 and a spring 4. The outer surface of the plug 5 is provided with an annular portion 9, which contacts the inner wall of the liquid dispensing channel 14. The surface of the plug 5 and above the annular portion 9 is provided with a conical portion 10, which fits against the inner wall of the plug 5. A spring 4 is movably sleeved on the plug 5. The spring 4 is made of stainless steel. The spring 4 and the plug 5 are designed to be detachable. The metal spring is more durable. The bottom of the spring 4 is connected to the annular portion 9, and the bottom end of the spring 4 extends into the inner cavity of the inner plug 2 and connects with its inner wall. The annular portion 9 and the conical portion 10 fit against the inner wall of the liquid dispensing channel 14 to form a sealing point 15.
[0041] The cover consists of an outer cover 8 and an inner cover 7. The inner cover 7 is installed inside the cavity of the outer cover 8, and a sealing sleeve 13 is provided inside the inner cover 7.
[0042] The shoulder sleeve 6 is connected with a thread 11, and the inner wall of the inner cover 7 is provided with a threaded groove corresponding to the thread 11. The inner cover 7 and the shoulder sleeve 6 are connected by the thread 11 and the threaded groove.
[0043] The inner cover 7 has a groove 17 on its outside, and the outer cover 8 has a rib 12 installed on its inner wall. The rib 12 is inserted into the cavity of the groove 17 to fix the inner cover 7 and the outer cover 8.
[0044] The sealing sleeve 13 is designed to fit the shape of the shoulder sleeve 6. Its internal shape is adapted to the shape of the shoulder sleeve 6, and the sealing sleeve 13 contacts the top of the shoulder sleeve 6 to form a second sealing point 16. The second sealing point 16 and the first sealing point 15 form a double seal, which can effectively prevent liquid leakage.
[0045] In use, rotate the outer cap 8 counterclockwise to remove it from the shoulder cover 6. Then, invert the bottle body 1 so that the bottle opening faces downwards, and place the end of the plug 5 against a cotton pad or gently press the plug 5 with your palm. This will compress the spring 4 under pressure, causing the end of the plug 5 to retract into the inner cavity of the liquid outlet channel 14. At this point, the annular part 9 and the conical part 10 separate from the inner wall of the liquid outlet channel 14, and the sealing point 15 disappears. The solution inside the bottle body 1 will then automatically flow out through the inner stopper 2 and the liquid outlet channel 14. Squeezing the bottle body 1 will generate pressure through deformation, which can accelerate the dispensing speed.
[0046] After use, remove the force pressing against the end of the plug 5. At this time, the spring 4 will rebound and reset, thereby pushing the plug 5 to move, so that the annular part 9 and the conical part 10 abut against the inner wall of the liquid outlet channel 14 to form a sealing point 15, thus achieving a seal. The inner cavity of the liquid outlet channel 14 is then blocked again, and the liquid in the bottle 1 will not flow out. Then, through the engagement between the internal threads and the screw threads 11 of the inner cover 7, the inner cover 7 is put on the shoulder sleeve 6 and rotated clockwise to fix the cover. After fixing, the inner wall of the sealing sleeve 13 contacts and fits against the outer side of the top of the shoulder sleeve 6 to form a second sealing point 16, thus achieving a second layer of seal. With the use of the first sealing point 15, liquid leakage can be effectively prevented.
