Description

Technical Field

[0001] The utility model belongs to the field of bottles and relates to a bottle body assembly and a lotion bottle. Background Art

[0002] With the growth of people's demand for personal care and beauty products, the lotion bottle, as an important packaging form, has been widely used in the market. Existing lotion bottles are mainly divided into various types such as pressing type, squeezing type and pump type. Among them, the pressing type lotion bottle has become the market mainstream due to its convenient use, good sealing performance and other characteristics. The pressing type lotion bottle realizes the extraction and release of lotion through the pump head assembly at the top, and its structure mainly includes a bottle body, a pump head assembly, a valve system and other parts. The bottle body is usually made of plastic material, with good transparency and lightness; the pump head assembly includes a pump head, a spring, a straw, etc., and users can easily squeeze the lotion out of the bottle through the connecting sleeve head; the valve system is responsible for controlling the inlet and outlet of the lotion to ensure the smoothness and safety of use.

[0003] Although the pressing type lotion bottle brings many conveniences to consumers, there are still some deficiencies in the actual use process. Especially for products in lotion form, due to their relatively poor fluidity, they are prone to adhere to the inner wall of the bottle, resulting in difficulty in completely squeezing out the remaining lotion in the bottle. According to statistics, on average, about 5% - 10% of the lotion remains in the bottle after each lotion bottle is used up. This problem not only affects the user experience of consumers, but also causes waste of lotion resources. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a bottle body assembly and a lotion bottle, which can fully squeeze out the lotion in the lotion bottle, improve the use experience and reduce the waste of lotion resources.

[0005] To solve the above technical problems, the utility model provides a bottle body assembly, including a bottle body with an upper opening. The upper end of the bottle body is threadedly connected with a cover body. A pump body is arranged in the middle of the cover body. A spray head cover slidably connected with the pump body is sleeved outside the upper end of the pump body. A spring chamber is arranged above and a liquid storage chamber is arranged below in the pump body. A nozzle is arranged on one side of the spray head cover. A spray pipe passing through and slidably connected with the spring chamber is arranged downward in the middle of the spray head cover. A pressure plate is arranged on the upper part of the spray pipe in the spring chamber. The outer diameter of the pressure plate is smaller than the inner diameter of the spring chamber. A ventilation hole communicating with the inside of the spray head cover is opened at the top of the spring chamber. An air suction hole is opened at the upper part of the spray head cover. A return spring sleeving the spray pipe is arranged between the pressure plate and the bottom of the spring chamber;

[0006] The outer diameter of the liquid storage cavity is smaller than the inner diameter of the spring cavity. An air inlet hole communicating with the bottle body is opened downward at the bottom of the spring cavity. An elastic rubber ring for blocking the air inlet hole is connected to the outer wall at the upper end of the liquid storage cavity. A piston slidably connected to its inner wall is arranged in the liquid storage cavity of the spray pipe. A liquid inlet hole smaller than its inner diameter is opened at the lower end of the spray pipe. A sliding column is slidably connected to the liquid inlet hole. A sealing cover is arranged at the upper end of the sliding column. The outer diameter of the sealing cover is larger than the inner diameter of the liquid inlet hole and smaller than the inner diameter of the spray pipe. A limiting head is arranged at the lower end of the sliding column. Liquid inlet channels vertically arranged are formed in the outer walls of the sliding column and the limiting head. The lower end of the liquid storage cavity is V-shaped. A hole-blocking ball is arranged at the lower end of the liquid storage cavity. A connecting sleeve is arranged downward at the lower end of the liquid storage cavity. A liquid guiding pipe communicating with the connecting sleeve is detachably connected to the connecting sleeve.

[0007] By adopting the above technical solution, when pressing the nozzle cover, the spray pipe is pushed downward, driving the pressing disc and the piston to move downward. The pressing disc moves downward to compress the return spring. When the piston moves downward, the emulsion or air in the liquid storage cavity is extruded, and under the action of the extrusion force, the sliding column is pushed upward, so that the sealing cover does not block the liquid inlet hole, and the emulsion can enter the spray pipe along the liquid inlet channel and is finally sprayed out through the nozzle on the nozzle cover;

[0008] After releasing the nozzle cover, under the action of the return spring, the nozzle cover is pushed to drive the spray pipe to move upward, pulling the piston to move upward, generating negative pressure in the liquid storage cavity. The negative pressure pulls the sliding column to move downward, so that the sealing cover blocks the liquid inlet hole. The hole-blocking ball moves upward under the action of the negative pressure, so that the emulsion enters the liquid storage cavity through the liquid guiding pipe and is temporarily stored. During the process, the air pressure in the bottle body decreases, causing the elastic rubber ring to deform and open the air inlet hole, so that the air flow enters the bottle body to maintain the air pressure balance in the bottle body.

[0009] The present utility model is further configured such that a sliding collar slidably connected to the outer wall of the nozzle cover is arranged upward at the upper end of the cover body.

[0010] The present utility model is further configured such that a dust-proof cover for covering the nozzle cover is detachably connected to the sliding collar.

[0011] The present utility model is further configured such that an inverted V-shaped liquid inlet notch is opened at the lower end of the liquid guiding pipe.

[0012] The present utility model is further configured such that the hole-blocking ball is a metal ball.

[0013] The present utility model further provides an emulsion bottle. The liquid guiding tube includes a connecting section connected to the connecting sleeve and a sliding section extending downward to the bottom of the bottle body. The outer diameter of the sliding section is smaller than that of the connecting section. An elastic scraping disc that can enter from the opening of the bottle body is slidably connected to the sliding section. The outer diameter of the elastic scraping disc is equal to the inner diameter of the bottle body, and a sliding hole for sealing and slidable connection with the sliding section is provided in the middle of the elastic scraping disc.

[0014] By adopting the above technical solution, during the process of the continuous reduction of the emulsion in the bottle body, the elastic scraping disc gradually moves downward along with the liquid level of the emulsion, scraping off the emulsion attached to the inner wall of the bottle body. And during the process of the emulsion being sucked away, the negative pressure generated in the emulsion attracts the elastic scraping disc to move downward, always ensuring that the emulsion in the bottle body is not hollow, facilitating pressing and sucking out, and avoiding waste.

[0015] The present utility model is further configured such that the elastic scraping disc is made of polyurethane material.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] Firstly, the present utility model adopts a brand-new pressing pump structure, which has a simpler structure and fewer components. And when in use by pressing, it can quickly adaptively maintain the air pressure balance in the bottle body, and can also keep the emulsion in the bottle body sealed, without any liquid leakage.

[0018] Secondly, the present utility model utilizes the elastic scraping disc in the bottle body. During the process of the continuous reduction of the emulsion in the bottle body, along with the gravity and the negative pressure generated during the suction of the emulsion, it continuously moves downward to scrape off the emulsion on the bottle wall and compact the lower emulsion, ensuring that the emulsion in the bottle body is not hollow, and there will be no emulsion attached to the inner wall causing waste, thus improving the use experience.

Detailed implementation mode

[0025] The following further details a bottle body assembly and a lotion bottle proposed by the present utility model in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present utility model will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present utility model. The same or similar reference numerals in the drawings represent the same or similar components.

[0026] Example, referring to Figures 1-5 , a bottle body assembly and a lotion bottle, including a bottle body 1 with an open upper end, a cap body 2 is threadedly connected to the upper end of the bottle body 1, a pump body 3 is arranged in the middle of the cap body 2, a nozzle cover 4 which is slidably connected to it is sleeved on the upper end of the pump body 3, an upwardly arranged sliding collar 5 which is slidably connected to the outer wall of the nozzle cover 4 is arranged at the upper end of the cap body 2, and a dust cover 6 which is detachably connected to the sliding collar 5 and is used to cover the nozzle cover 4 is provided. A spring chamber 7 located above and a liquid storage chamber 8 located below are arranged in the pump body 3, a nozzle 9 is arranged on one side of the nozzle cover 4, a spray pipe 10 which penetrates through the spring chamber 7 and is slidably connected to it is arranged downward in the middle of the nozzle cover 4, a pressure plate 11 is arranged at the upper part of the spray pipe 10 in the spring chamber 7, the outer diameter of the pressure plate 11 is smaller than the inner diameter of the spring chamber 7, which is convenient for maintaining the air pressure balance above and below the pressure plate 11. Four ventilation holes 12 communicating with the inside of the nozzle cover 4 are opened at the top of the spring chamber 7, two suction holes 13 are opened at the upper part of the nozzle cover 4, and a return spring 14 sleeved on the spray pipe 10 is arranged between the pressure plate 11 and the bottom of the spring chamber 7, and an upward elastic force is provided for the nozzle cover 4 through the return spring 14.

[0027] The outer diameter of the liquid storage cavity 8 is smaller than the inner diameter of the spring cavity 7. Six air inlet holes 15 communicating with the bottle body 1 are opened downward at the bottom of the spring cavity 7. An elastic rubber ring 16 for blocking the air inlet holes 15 is connected to the outer wall at the upper end of the liquid storage cavity 8. When the air flow passes downward through the air inlet holes 15, it pushes the elastic rubber ring 16 to deform, opening the air inlet holes 15 and allowing the air flow to enter the bottle body 1. A piston 17 slidably connected to its inner wall is arranged in the liquid storage cavity 8 of the spray pipe 10. A liquid inlet hole 18 smaller than its inner diameter is opened at the lower end of the spray pipe 10. A sliding column 19 is slidably connected to the liquid inlet hole 18. A sealing cover 20 is arranged at the upper end of the sliding column 19. The outer diameter of the sealing cover 20 is larger than the inner diameter of the liquid inlet hole 18 and smaller than the inner diameter of the spray pipe 10. The sealing cover 20 can block the liquid inlet hole 18 downward. A limiting head 21 is arranged at the lower end of the sliding column 19. Four vertically arranged liquid inlet channels 22 are opened on the outer walls of the sliding column 19 and the limiting head 21, enabling the emulsion to enter the spray pipe 10 along the liquid inlet channels 22. The lower end of the liquid storage cavity 8 is V-shaped. A hole-blocking ball 23 is arranged at the lower end of the liquid storage cavity 8. The hole-blocking ball 23 is a metal ball. When only under the action of gravity in the normal state, the hole-blocking ball 23 blocks the lower end of the liquid storage cavity 8. A connecting sleeve 24 is arranged downward at the lower end of the liquid storage cavity 8. A liquid guiding pipe communicated with it is detachably connected to the connecting sleeve 24. An inverted V-shaped liquid inlet notch 25 is opened at the lower end of the liquid guiding pipe, facilitating the entry of the emulsion at the bottom of the emulsion.

[0028] The liquid guiding pipe includes a connecting section 26 connected to the connecting sleeve 24 and a sliding section 27 extending downward to the bottom of the bottle body 1. The outer diameter of the sliding section 27 is smaller than that of the connecting section 26. An elastic scraping disc 28 capable of entering from the opening of the bottle body 1 is slidably connected to the sliding section 27. The elastic scraping disc 28 is made of polyurethane material. The outer diameter of the elastic scraping disc 28 is equal to the inner diameter of the bottle body 1. A sliding hole 29 sealed and slidably connected to the sliding section 27 is opened in the middle of the elastic scraping disc 28. After injecting the emulsion into the bottle body 1, the elastic scraping disc 28 is sleeved on the sliding section 27 and folded and placed into the bottle body 1 from the opening. After entering, it automatically slowly unfolds and adheres tightly to the inner wall of the bottle body 1, and during the process, it descends to contact the liquid level of the emulsion.

[0029] Working principle: When pressing the nozzle cover 4, the spray pipe 10 is pushed downward, driving the pressing disc 11 and the piston 17 to move downward. The pressing disc 11 moves downward to compress the return spring 14. When the piston 17 moves downward, it squeezes the emulsion or air in the liquid storage cavity 8, and under the action of the squeezing force, it pushes the sliding column 19 upward, so that the sealing cover 20 does not block the liquid inlet hole 18, and the emulsion can enter the spray pipe 10 along the liquid inlet channels 22 and is finally sprayed out through the nozzle 9 on the nozzle cover 4;

[0030] After the nozzle cover 4 is released, under the action of the return spring 14, the nozzle cover 4 is pushed to drive the nozzle tube 10 to move upward, pulling the piston 17 upward, generating a negative pressure in the liquid storage cavity 8. The negative pressure pulls the sliding column 19 downward, causing the sealing cover 20 to block the liquid inlet hole 18. The plugging ball 23 moves upward under the action of the negative pressure, enabling the emulsion to enter the liquid storage cavity 8 through the liquid guiding tube and be temporarily stored. During this process, the air pressure in the bottle body 1 decreases, causing the elastic rubber ring 16 to deform and open the air inlet hole 15, allowing air to enter the bottle body 1 to maintain the air pressure balance in the bottle body 1;

[0031] During the process of the emulsion in the bottle body 1 continuously decreasing, the elastic scraping disc 28 gradually moves downward along with the liquid level of the emulsion, scraping the emulsion adhering to the inner wall of the bottle body 1. Additionally, during the process of the emulsion being sucked away, the negative pressure generated in the emulsion attracts the elastic scraping disc 28 to move downward, always ensuring that the emulsion in the bottle body 1 is not hollow, facilitating pressing and sucking out, and avoiding waste.

[0032] It should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts between the various embodiments, reference can be made to each other.

[0033] The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the field of the present invention based on the above disclosure shall fall within the protection scope of the claims.
