Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, and in particular to an antistatic polymer vacuum bottle based on a bottomless square structure. Background Technology

[0002] In the modern cosmetics, skin care and personal care products industry, vacuum bottles are a common packaging container. They are widely used because they can effectively prevent product oxidation and contamination and are convenient for users to use. Traditional vacuum bottles mostly adopt a round structure. This design is easy to roll during transportation and storage, which increases the risk of breakage and also takes up more space.

[0003] To address this issue, some square-structured vacuum bottles exist on the market to improve stability and reduce the risk of rolling and breakage. However, these square-structured vacuum bottles, like ordinary vacuum bottles, still have certain drawbacks in practical use: Currently, most vacuum bottle caps are vacuum pump caps, requiring pressing to operate. This design necessitates an additional cap for protection against compression, making them convenient to carry. However, the cap itself is easily lost, making it difficult to take the bottle out if missing. Therefore, a vacuum bottle with a locking function to limit its movement is needed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the cap itself is easily lost in the existing technology, and it is difficult to carry it when it is missing. The invention proposes an antistatic polymer vacuum bottle based on a bottomless square structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vacuum bottle made of antistatic polymer material based on a bottomless square structure, comprising:

[0007] The bottle body includes an outer bottle and an inner bottle nested inside the outer bottle. The top of the outer bottle is integrally formed with a central bundle, and the top of the inner bottle is fixedly connected to the inner peripheral wall of the central bundle.

[0008] The vacuum pump cap is fitted onto the outer peripheral wall of the central beam;

[0009] The locking mechanism includes four inserts, four housings fixed to the bottom of the vacuum pump cap, and four insertion holes opened on the outer peripheral wall of the middle beam; the inserts are slidably fitted into the inner cavity of the housing, and one end of the inserts is engaged with the insertion hole.

[0010] The insert has a groove on one side, and an inner plate extending into the groove is fixed to the inner wall of the outer shell. A compression spring is provided between the inner wall of the groove and the inner plate, so that the insert tends to extend outward under the action of the compression spring.

[0011] As a further improvement to the above technical solution:

[0012] The locking mechanism also includes a rotating ring rotatably disposed on the top of the vacuum pump bottle cap. A top plate passing through the through hole of the vacuum pump bottle cap is fixed on the top of the insert. An inclined surface is provided on one side of the top plate. A side block abutting against the inclined surface is fixed on the inner wall of the rotating ring.

[0013] When the rotating ring is rotated, the side block presses against the inclined surface to drive the insert to retract into the outer shell, releasing the lock between the insert and the socket. After the rotating ring is released, the compression spring pushes the insert to insert into the socket to fix the vacuum pump bottle cap to the bottle body.

[0014] A torsion spring is provided between the rotating ring and the top of the vacuum pump bottle cap. The two ends of the torsion spring are fixedly connected to the rotating ring and the vacuum pump bottle cap, respectively, so that the rotating ring automatically resets without external force.

[0015] The locking mechanism also includes a stop ring, and two semi-arc plates symmetrically distributed on the outer periphery of the stop ring are fixed on the top of the rotating ring. The top of the stop ring is provided with a concave surface that matches the shape of the vacuum pump bottle cap pump head.

[0016] When the rotating abutment ring causes the concave surface to deviate from the pump head, the abutment ring restricts the downward pressure of the pump head; when the concave surface is aligned with the pump head, the restriction is released.

[0017] The abutment ring and the semi-arc plate are interference fit, which gives the abutment ring a positioning friction force when it rotates.

[0018] The outer peripheral wall of the middle beam is covered with a rubber pad, which forms a sealed contact with the inner wall of the vacuum pump bottle cap.

[0019] The outer and inner bottles are made of antistatic polymer materials, which are either polypropylene with a surface composite conductive layer or polyethylene filled with carbon fibers.

[0020] The inner cavity of the outer shell is provided with a guide protrusion, and the insert is provided with a guide groove that slides with the guide protrusion, restricting the insert to move only along the axial direction.

[0021] The depth of the insertion hole is greater than 1.2 times the extension length of the insertion strip, and the inner wall of the insertion hole is provided with a chamfer that matches the tapered surface of the insertion strip end.

[0022] In this application, during actual use, rotating the rotating ring will cause the internal side block to rotate, and the side block will abut against the inclined surface, thereby pushing the top plate to move. The top plate will then move the insert, causing the insert to retract into the interior of the outer shell. Subsequently, the vacuum pump cap can be placed on the middle of the bottle body. Afterward, the rotating ring will be reset by the torsion spring, and the insert will be reset by the force of the compression spring, so that one end of it is inserted into the insertion hole, completing the assembly. When storing or carrying the vacuum pump, rotating the abutting ring will cause the concave surface to be misaligned with the pump head of the vacuum pump cap. At this time, the vacuum pump cap will not be able to be pressed. When it is needed, simply rotate the concave surface to the bottom of the pump head of the vacuum pump cap to release the restriction.

[0023] In this utility model, the antistatic polymer vacuum bottle based on a bottomless square structure can connect and fix the bottle body and the vacuum pump cap through a locking mechanism, thereby facilitating actual installation and subsequent disassembly. At the same time, it can limit the pump head to prevent accidental pressing and increase its practicality.

[0024] In this utility model, the antistatic polymer vacuum bottle based on a bottomless square structure can achieve greater stability and prevent rolling during storage and transportation. Furthermore, the bottle body is made of antistatic polymer material, which effectively prevents static electricity from interfering with the contents of the bottle.

[0025] In this invention, the vacuum bottle can be assembled while the pump head of the vacuum pump cap is limited, preventing it from being pressed in the locked state. This makes it easy to store and carry, and is convenient to use without complicated operations. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Example 1

[0033] Reference Figure 1-2 The vacuum bottle includes: a bottle body, a vacuum pump cap 2, and a locking mechanism.

[0034] The bottle body consists of an outer bottle 1 and an inner bottle 4 located inside the outer bottle 1. Both the outer bottle 1 and the inner bottle 4 are made of antistatic polymer material. The main material is polymer, and the antistatic properties are achieved by composite conductive layer or filling with conductive filler, which can effectively prevent static electricity from interfering with the contents of the bottle. A middle bundle 5 is fixedly installed at the top of the outer bottle 1, and the top of the inner bottle 4 is fixedly connected to the inner wall of the middle bundle 5, thus forming a sealed container structure.

[0035] Reference Figure 2-3 The vacuum pump cap 2 is fitted onto the outer wall of the middle bundle 5 and serves as the cap for the bottle body. A locking mechanism is provided to lock the outer bottle 1 and the vacuum pump cap 2. The locking mechanism is located at the bottom of the vacuum pump cap 2 and includes four inserts 12, four outer shells 13, a compression spring 11, a rotating ring 3, a side block 8, a torsion spring 7, and a stop ring 17.

[0036] The vacuum pump bottle cap 2 has four outer shells 13 fixedly mounted on its bottom, and four inserts 12 are slidably mounted inside the outer shells 13. A groove is formed on one side of each insert 12, and an inner plate 14 is fixedly mounted on the inner wall of one side of each outer shell 13. The inner plate 14 is located inside the groove, and a compression spring 11 is fixedly mounted between the inner wall of one side of the groove and the inner plate 14. The compression spring 11 allows the inserts 12 to remain in an outwardly extended state when no external force is applied.

[0037] The outer wall of the middle beam 5 has four insertion holes 6. One end of each of the four insertion strips 12 is engaged with the four insertion holes 6. When the insertion strips 12 are inserted into the insertion holes 6, the outer bottle 1 and the vacuum pump cap 2 can be locked.

[0038] A rotating ring 3 is provided to drive the movement of the insert 12. The rotating ring 3 is rotatably mounted on the top of the vacuum pump cap 2. A top plate 15 is fixedly mounted on the top of the insert 12. Four through holes 9 are opened at the bottom of the vacuum pump cap 2. The top of the top plate 15 extends into the interior of the rotating ring 3 through adjacent through holes 9. Four side blocks 8 are fixedly mounted on the inner wall of the rotating ring 3. An inclined surface 10 is opened on one side of the top plate 15, and the four side blocks 8 respectively cooperate with the four inclined surfaces 10. When the rotating ring 3 is rotated, the side blocks 8 will press against the inclined surfaces 10, thereby pushing the top plate 15 and the insert 12 inward, thus unlocking the device.

[0039] A torsion spring 7 is fixedly installed between the inner wall of the rotating ring 3 and the top of the cap of the vacuum pump bottle cap 2. When the rotating ring 3 is released, the torsion spring 7 will drive the rotating ring 3 to reset.

[0040] Specifically, by rotating the rotating ring 3, the rotating ring 3 will drive the internal side block 8 to rotate, and the side block 8 will abut against the inclined surface 10, thereby pushing the top plate 15 to move. The top plate 15 drives the insert 12 to move, so that the insert 12 retracts into the inside of the outer shell 13. Then the vacuum pump bottle cap 2 can be placed on the middle bundle 5 of the bottle body. After that, the rotating ring 3 is reset by the torsion spring 7, and the insert 12 is reset by the force of the compression spring 11, so that one end of it is inserted into the inside of the socket 6, completing the assembly.

[0041] This application can be used in the field of packaging containers, or in other fields applicable to this application.

[0042] Example 2

[0043] refer to Figure 4 An improvement based on Example 1: A vacuum bottle made of antistatic polymer material with a bottomless square structure is applied to the packaging container field. Two semi-arc plates 18 are fixedly installed on the top of the rotating ring 3, and both semi-arc plates 18 are fitted onto the outer wall of the abutment ring 17. The top of the abutment ring 17 has a concave surface 16, which cooperates with the pump head of the vacuum pump bottle cap 2.

[0044] Specifically, when storing or carrying the vacuum pump bottle cap 2, rotating the retaining ring 17 causes the concave surface 16 to be offset from the pump head portion of the vacuum pump bottle cap 2. In this state, the vacuum pump bottle cap 2 cannot be pressed. When needed, simply rotate the concave surface 16 to below the pump head of the vacuum pump bottle cap 2 to release the restriction. This design not only enables vacuum bottle assembly but also limits the pump head of the vacuum pump bottle cap 2, preventing it from being pressed in a locked state. This facilitates practical storage and carrying, making it convenient to use without complicated operations.

[0045] To increase the seal between the middle beam 5 and the vacuum pump cap 2, a rubber gasket is installed on the outer wall of the middle beam 5.

[0046] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
