Description

Technical Field

[0001] The utility model relates to a packaging container, in particular to a solid-liquid separation bottle cap. Background Art

[0002] There are roughly two types of solid-liquid separation bottle caps. One type is that after the material in the storage cylinder falls into the bottle, the storage cylinder needs to be removed before the liquid can be poured out. This type of bottle cap is more troublesome to use. Especially for substances with a certain viscosity such as honey, sticky substances will stick to the hands when removing the storage cylinder, making it inconvenient to use. The other type is a bottle cap that can pour out beverages without a storage cylinder. For example, a swaged flip-type bottle cap disclosed in the patent document with the publication number CN221661418U adopts the following technical solution: it includes a main bottle cap, a storage cap, and a screw cap. The storage cap is threadedly connected inside the main bottle cap. A linkage block is arranged inside the screw cap, and a linkage protrusion is arranged inside the storage cap. The screw cap can drive the storage cap to rotate through the cooperation of the linkage block and the linkage protrusion. Under the cooperation of the external thread and the internal thread, the sealed flip plate is opened. After this type of bottle cap is opened, the liquid can be poured out without removing the storage cylinder. However, it requires a thread to be arranged between the main bottle cap and the storage cap, a linkage block to be arranged inside the screw cap, and a linkage protrusion to be arranged inside the storage cap, which results in a relatively complex structure of the bottle cap, high mold cost, and low production efficiency. Content of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a sealing cap with a simple structure.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0005] A solid-liquid separation bottle cap with a simple structure includes a bottle cap seat, a top-opening member, and a screw cap. A connecting portion for connecting the bottle body is arranged at the lower end of the bottle cap seat, and an external thread is arranged at the upper end. The screw cap is provided with an internal thread, and the screw cap is threadedly connected to the upper end of the bottle cap seat through the cooperation of the external thread and the internal thread; an axial storage cylinder is arranged at the center of the bottle cap seat, a sealing sheet is integrally formed at the lower end of the storage cylinder, and a tearing portion is arranged between the sealing sheet and the storage cylinder; the top-opening member is installed inside the storage cylinder, and an anti-rotation structure for preventing the top-opening member from rotating circumferentially relative to the storage cylinder is arranged between the top-opening member and the storage cylinder; an extrusion inclined surface for pushing the top-opening member to move towards the sealing sheet is arranged inside the screw cap, and the inclination direction of the extrusion inclined surface is opposite to the inclination direction of the internal thread. When the screw cap is rotated to open, the extrusion inclined surface pushes the top-opening member to move axially, extruding the sealing sheet to cause partial or complete fracture of the tearing portion.

[0006] The anti-rotation structure includes anti-rotation ribs provided on the inner wall of the storage cylinder and anti-rotation strips on the outer side of the ejecting member. A plurality of anti-rotation ribs are provided, and a limiting area is formed between two adjacent anti-rotation ribs. The anti-rotation strip is located in the limiting area.

[0007] A pushing strip is provided on the outer wall of the ejecting member, and the top of the pushing strip contacts the extrusion inclined surface.

[0008] The top of the pushing strip is provided with a guiding inclined surface having the same inclined direction as the extrusion inclined surface.

[0009] The ejecting member is in a cylindrical shape adapted to the shape of the storage cylinder, and the lower end of the ejecting member is provided with ejecting teeth and avoidance vacancies.

[0010] A mesh sheet is integrally formed at the upper end of the ejecting member.

[0011] A ring-shaped protrusion is provided on the outer wall of the ejecting member, and a retaining ring is provided on the inner wall of the storage cylinder. After the ejecting member extrudes the sealing sheet to cause partial or complete fracture of the tearing portion, the height of the ring-shaped protrusion is lower than that of the retaining ring. When pouring the liquid, the ring-shaped protrusion is blocked by the retaining ring.

[0012] An anti-theft ring is integrally formed at the lower end of the screw cap.

[0013] Anti-slip lines for increasing friction are provided on the outer walls of the bottle cap seat and the screw cap.

[0014] The beneficial effects of the present utility model are as follows: The present utility model realizes opening by pushing the ejecting member to move with the extrusion inclined surface, without the need to provide a thread between the ejecting member and the bottle cap seat, which simplifies the structure of the product and the die structure, improves the production efficiency, and moreover, since the inclined direction of the extrusion inclined surface is opposite to the inclined direction of the internal thread of the screw cap, it can realize ejecting the sealing sheet while rotating the screw cap to open.

[0024] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments may be combined with each other.

[0025] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model.

[0026] Refer to Figures 1 to 8, A solid-liquid separation bottle cap with a simple structure, including a bottle cap seat 1, a top-opening part 2 and a screw cap 3. The lower end of the bottle cap seat 1 is provided with a connecting part for connecting the bottle body, and the upper end is provided with an external thread. The screw cap 3 is provided with an internal thread, and the screw cap 3 is threadedly connected to the upper end of the bottle cap seat 1 through the cooperation of the external thread and the internal thread; An axial storage cylinder 11 is provided in the center of the bottle cap seat 1. The brewing materials contained in the storage cylinder 11 can be solid brewing materials insoluble in water such as tea leaves and lemon slices, or powdered brewing materials after extraction and drying such as coffee powder and soy milk powder, or liquid brewing materials such as honey and syrup. A sealing piece 12 is integrally formed at the lower end of the storage cylinder 11, and a tearing part is provided between the sealing piece 12 and the storage cylinder 11; The tearing part can be provided at the bottom end of the storage cylinder or on the side wall. In this embodiment, the tearing part is provided at the bottom end of the storage cylinder as an example for illustration; The top-opening part 2 is installed in the storage cylinder 11, and an anti-rotation structure is provided between the top-opening part 2 and the storage cylinder 11 to prevent the top-opening part 2 from rotating circumferentially relative to the storage cylinder 11; An extrusion inclined surface 31 for pushing the top-opening part 2 to move towards the sealing piece 12 is provided in the screw cap 3. The inclination direction of the extrusion inclined surface 31 is opposite to the inclination direction of the internal thread. When the screw cap 3 is rotated to open, the extrusion inclined surface 31 pushes the top-opening part 2 to move axially, squeezing the sealing piece 12 to cause partial or complete fracture of the tearing part; The present utility model uses the extrusion inclined surface to push the top-opening part to move to achieve opening, without the need to set a thread between the top-opening part and the bottle cap seat, simplifies the structure of the product and the mold structure, improves the production efficiency, and moreover, since the inclination direction of the extrusion inclined surface is opposite to the inclination direction of the internal thread of the screw cap, it can achieve opening the sealing piece while rotating the screw cap to open. After opening, the liquid can be poured out without taking out the top-opening part, which is simple and convenient to use; And because during the brewing process, the inside of the bottle body is always isolated from the external environment, the liquid in the bottle will not be contaminated by external bacteria and dust, etc., which is more convenient and hygienic.

[0027] The anti-rotation structure includes anti-rotation ribs 13 provided on the inner wall of the storage cylinder 11 and anti-rotation strips 21 on the outer side of the top-opening part 2. There are multiple anti-rotation ribs 13, and a limiting area is formed between adjacent two anti-rotation ribs 13, and the anti-rotation strips 21 are located in the limiting area. The anti-rotation ribs and anti-rotation strips are provided to prevent the top-opening part from rotating with the screw cap when the screw cap is screwed, and the anti-rotation ribs can hold the top-opening part and limit its rotation.

[0028] A pushing strip 22 is provided on the outer wall of the top-opening part 2, and the top of the pushing strip 22 is in contact with the extrusion inclined surface 31; A guiding inclined surface with the same inclination direction as the extrusion inclined surface 31 is provided at the top of the pushing strip 22. The guiding inclined surface abuts against the extrusion inclined surface and slides along the inclination direction of the extrusion inclined surface to realize the sliding of the top-opening part.

[0029] The ejecting member 2 is in a cylindrical shape adapted to the shape of the storage cylinder 11. At the lower end of the ejecting member 2, there are ejecting teeth 23 and avoidance voids 24. When the ejecting member pushes open the sealing piece, the part squeezed by the ejecting teeth breaks, while the part at the avoidance voids remains connected to the storage cylinder. In this way, the brewing material in the storage cylinder can contact the liquid in the bottle, and at the same time, the sealing piece will not fall into the bottle.

[0030] At the upper end of the ejecting member 2, a mesh sheet 25 is integrally formed. When pouring out the mixed liquid in the bottle, the liquid is poured out from the through holes of the mesh sheet. At the same time, when the brewing material is larger-sized tea leaves or other objects, the mesh sheet can play a role in blocking the brewing material and only pour out the brewed liquid, making it more convenient to use; the manufacturer can adjust the aperture of the through holes according to the volume of the brewing material to prevent the brewing material from falling out of the through holes.

[0031] On the outer wall of the ejecting member 2, there is an annular protrusion 26. On the inner wall of the storage cylinder 11, there is a retaining ring 14. After the ejecting member 2 squeezes the sealing piece 12 to cause partial or complete fracture of the tearing part, the height of the annular protrusion 26 is lower than that of the retaining ring 14. When pouring the liquid, the annular protrusion 26 is blocked by the retaining ring 14; in this embodiment, when the bottle cap is in a closed state, the position of the annular protrusion is higher than that of the retaining ring. After screwing the screw cap to make the ejecting member pierce through the sealing piece, the position of the annular protrusion is lower than that of the retaining ring. When pouring the liquid in the bottle, the retaining ring can block the annular protrusion to prevent the ejecting member from slipping out of the bottle cap seat.

[0032] At the lower end of the screw cap 3, an anti-theft ring 32 is integrally formed. Setting the anti-theft ring can enhance the sealing performance of the bottle cap, help prevent external pollutants such as bacteria and viruses from entering the bottle body through the bottle mouth, and at the same time can also prevent the contents of the bottle body from being counterfeited or replaced.

[0033] On the outer walls of the bottle cap seat 1 and the screw cap 3, there are anti-slip patterns for increasing the friction force. Setting the anti-slip patterns increases the friction force between the hand and the bottle cap seat and the screw cap, facilitating the user to screw the bottle cap.

[0034] The utility model can be produced and filled together with the bottle body, or bottle caps of sizes such as 28mm, 30mm, 38mm in line with national standards can be produced. When in use, directly replace the bottle caps of sizes such as 28mm, 30mm, 38mm on ordinary mineral water bottles with the solid-liquid separation bottle cap of the utility model for brewing.
