Description

Technical Field

[0001] This utility model belongs to the field of vacuum bottle technology, specifically relating to a novel replaceable vacuum bottle. Background Technology

[0002] Vacuum bottles are containers widely used in cosmetics, personal care products, pharmaceutical packaging, and laboratory supplies. Their main function is to effectively preserve the contents through the principle of negative pressure, preventing them from oxidizing and deteriorating due to contact with outside air, thereby extending the shelf life of the products and maintaining their effectiveness. Traditional vacuum bottle designs typically include a bottle body, pump body base, piston, and push button. The bottle body is used to store the contents, the pump body base integrates the pumping mechanism, and the contents are extracted and released by pressing the push button. The piston moves within the bottle to maintain a vacuum environment.

[0003] However, traditional vacuum bottles are difficult to replace once the piston is damaged, rendering them unusable, increasing operating costs and wasting resources. Furthermore, when operators press the nozzle to extract the contents, the smooth surface of the bottle, especially in sweaty or damp environments, makes it easy for their hands to slip, affecting ease of use and potentially causing the bottle to tip over or spill its contents due to improper force, resulting in unnecessary waste and safety hazards. Therefore, this utility model proposes a novel replaceable vacuum bottle. Utility Model Content

[0015] Preferably, the surface of the pump body seat is provided with multiple strip-shaped protrusions.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: First, by improving and optimizing the existing vacuum bottle, the connection structure between the pump body base and the bottle body is optimized and a threaded unscrewing method is adopted, allowing the operator to easily remove and replace the piston inside the bottle, thereby realizing the reuse of the bottle body, reducing the cost of use and conforming to the concept of environmental protection. Second, an annular sealing ring is designed at the connection between the pump body base and the bottle body. Through its elastic deformation, it fills the connection gap, effectively ensuring the sealing of the connection between the two and preventing the infiltration of outside air. Third, an annular notch is opened on the bottle body and an annular anti-slip sleeve is installed. The anti-slip sleeve is made of a material with anti-slip properties, which can significantly increase the friction when the operator holds the bottle body, effectively preventing the palm from slipping when pressing the pump head, and improving the safety and convenience of use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Please see Figures 1 to 5 This is an embodiment of the present invention, which provides a technical solution: a novel replaceable vacuum bottle, comprising a bottle body 1, a piston block slidably disposed inside the bottle body 1, a pump seat 3 mounted on the top of the bottle body 1, and a bottle cap 2 sleeved on the top of the pump seat 3. All of the above structures are prior art; for specific structural principles, please refer to the existing patent with publication number CN204056736U, which will not be elaborated upon here. Simply put, pressing the pusher on the top of the pump seat 3 generates negative pressure, causing the piston inside the bottle body 1 to move upward, thereby realizing the extraction and release of the contents. It also includes...

[0026] An integral annular threaded seat 31 is provided at the bottom of the pump body seat 3, and the annular threaded seat 31 is screwed into the inner side of the bottle body 1. The annular threaded seat 31 is threadedly connected to the inner wall of the bottle body 1, realizing the installation between the pump body seat 3 and the bottle body 1. Later, the pump body seat 3 only needs to be screwed counterclockwise to make the annular threaded seat 31 rotated and unscrewed from the bottle body 1, so that the piston inside the bottle body 1 can be replaced. When replacing, the piston can be pulled out from the top opening of the bottle body 1.

[0027] And an annular sealing ring 4, which is fitted on the surface of the annular threaded seat 31 and located between the pump body seat 3 and the bottle body 1, ensures the sealing of the connection between the pump body seat 3 and the bottle body 1 and prevents liquid leakage.

[0028] The annular notch 11 on the surface of the bottle body 1 and the annular anti-slip sleeve 5 installed inside the annular notch 11 can play an anti-slip role when the operator holds the bottle body 1, so as to avoid the palm slipping due to the excessive smoothness of the surface of the bottle body 1.

[0029] In this embodiment, preferably, the upper and lower surfaces of the annular sealing ring 4 are provided with an integral annular protrusion 41, both of which are made of rubber material and will undergo elastic deformation when squeezed. The top surface of the bottle body 1 and the bottom surface of the pump body seat 3 are provided with annular grooves 32 corresponding to the annular protrusion 41, which further increases the sealing performance of the annular sealing ring 4 after it is compressed.

[0030] In this embodiment, preferably, the annular sealing ring 4 has two annular cavities inside that correspond to the annular protrusion 41, so that the annular protrusion 41 has sufficient deformation space when it is compressed.

[0031] In this embodiment, preferably, the inner wall of the annular sealing ring 4 is provided with an integral annular guide block 42. Both are made of rubber material and will undergo elastic deformation when squeezed. The surface of the annular threaded seat 31 is provided with an annular guide groove 311 corresponding to the annular guide block 42, and the annular guide block 42 is located in the annular guide groove 311, so that the annular sealing ring 4 can be stably fitted on the annular threaded seat 31 and will not slip directly from the bottom end of the annular threaded seat 31 during the disassembly and assembly of the pump body seat 3.

[0032] In this embodiment, preferably, the surface of the annular anti-slip sleeve 5 is provided with a plurality of integrated anti-slip protrusions 51, both of which are made of rubber material. When squeezed, they will undergo elastic deformation, further increasing the friction between the operator's palm and the annular anti-slip sleeve 5, and further improving the anti-slip effect.

[0033] In this embodiment, preferably, the inner wall of the annular notch 11 is provided with a plurality of T-shaped card seats 12 that are integral with the bottle body 1, and the inner wall of the annular anti-slip sleeve 5 is provided with a plurality of T-shaped slots 52 corresponding to the T-shaped card seats 12, and the T-shaped card seats 12 are inserted into the T-shaped slots 52, so that the annular anti-slip sleeve 5 can be stably installed in the annular notch 11 and is not easy to fall off.

[0034] In this embodiment, preferably, the bottle cap 2 is made of a transparent material, so that the operator can directly observe the status of the pusher and other structures on the pump body base 3 through the bottle cap 2.

[0035] In this embodiment, preferably, the surface of the pump body seat 3 is provided with multiple strip-shaped protrusions, which facilitates the subsequent rotation and twisting of the pump body seat 3 by the operator and plays a role in preventing slippage.

[0036] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
