Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to a combined bottle cap based on pressing out powder. Background Art

[0002] In the fields of food and health products, pre-mixed liquid forms are often used, such as beverages and oral liquids. However, the biggest problem with food and health products in pre-mixed liquid form is that they are easily affected by external factors and lose their activity and deteriorate, such as light, heat, oxygen, ultraviolet rays, etc. For this reason, some preservatives, preservatives, and stabilizers need to be added. Even so, the shelf life of pre-mixed liquids is still shorter than that of solids. In addition, during the storage of liquid preparations, the taste changes due to time and environment, which also restricts the development of various foods, such as anthocyanin-based, vitamin-based, and probiotic beverages. After being mixed with water, the active retention period is greatly shortened. With the increasing improvement of people's living standards, people are increasingly pursuing healthy bottled beverages. If a beverage bottle cap that can store solid ingredients and can be prepared as needed can be designed, before the user uses it, the nutritional ingredients and water are in a separated state, maintaining the activity of the raw materials and being prepared immediately upon use.

[0003] For this reason, the patent specification with the publication number of CN221139340U discloses a bottle cap for a liquid packaging bottle containing contents, including an outer cap, an inner cap, a storage cap, and an aluminum foil sealing film; the outer cap includes a cap, a sealing sleeve, and a rotating dial; the inner cap includes an outer tube part, an inner tube part, and a guiding protrusion; the storage cap includes a storage cylinder, and the inside of the storage cylinder is provided with a storage groove with an open lower end, and the outside of the storage cylinder is provided with a limiting ring, a driven dial, convex teeth, and a rotating rib. The inner cap, the storage cap, and the aluminum foil sealing film jointly enclose a storage area for the contents, which can reliably seal the contents and have a good quality preservation effect; by rotating the outer cap to drive the storage cap to rotate and press down, the convex teeth of the storage cap can pierce the aluminum foil sealing film, and the contents in the storage area for the contents will quickly fall into the bottle body of the liquid packaging bottle, and the release operation is simple.

[0004] This kind of bottle cap has deficiencies in use. One is that its rotation operation requires both hands, which is not conducive to single-handed operation of releasing powder, and the operation is not convenient enough; the other is that it is not conducive to the filling operation of powder. Therefore, its structure needs to be optimized and improved. Summary of the Invention

[0005] The purpose of the utility model is to overcome the above problems existing in the traditional technology and provide a combined bottle cap based on pressing out powder.

[0006] To achieve the above technical purpose and reach the above technical effect, the utility model is realized through the following technical solutions:

[0007] A combined bottle cap based on press-out powder, comprising a lower cover, an upper cover, an inner powder storage cover, an inner plug and an aluminum foil sheet. The upper cover is installed at the upper end of the lower cover. The inner powder storage cover is installed inside the lower cover. The inner plug is installed at the top end of the inner powder storage cover. The aluminum foil sheet is installed at the top end of the lower cover;

[0008] The lower cover includes a lower cover housing, a reducing pipe, an external thread pipe and an anti-detachment outer ring. A reducing pipe with a wider upper part and a narrower lower part is arranged inside the lower cover housing. An external thread pipe for installing the upper cover is installed between the lower cover housing and the upper part of the reducing pipe. An anti-detachment outer ring for preventing the upper cover from detaching is arranged near the top end on the outside of the external thread pipe. The bottom end surface of the reducing pipe serves as the installation surface of the aluminum foil sheet;

[0009] The inner powder storage cover includes a plug installation part, an annular part, a support plate part and a bottom pipe part arranged in sequence from top to bottom. The plug installation part is used for clamping and placing the inner plug. A cone for facilitating the outward sliding of the internal powder is arranged at the upper end of the bottom pipe part. A ring-shaped sealing protrusion is arranged on the outside of the bottom pipe part.

[0010] Further, in the above combined bottle cap based on press-out powder, an internal thread groove for facilitating installation on the bottle mouth is arranged at the lower part of the lower cover housing near the reducing pipe.

[0011] Further, in the above combined bottle cap based on press-out powder, anti-slip ridges are arranged on the outside of the lower cover housing.

[0012] Further, in the above combined bottle cap based on press-out powder, the upper cover includes an upper cover housing. An anti-detachment inner ring matched with the anti-detachment outer ring is arranged on the inner side of the lower part of the upper cover housing. An anti-theft seam is arranged above the anti-detachment inner ring on the upper cover.

[0013] Further, in the above combined bottle cap based on press-out powder, the axial length of the support plate part is less than the axial length of the reducing pipe.

[0014] Further, in the above combined bottle cap based on press-out powder, the sealing protrusion is in close fit with the inner cavity wall of the reducing pipe.

[0015] Further, in the above combined bottle cap based on press-out powder, a storage area for facilitating the axial displacement of the inner powder storage cover is arranged in the reducing pipe.

[0016] Further, in the above combined bottle cap based on press-out powder, when the upper cover is detached from the lower cover, by pressing down the inner powder storage cover, the bottom pipe part thereof is ejected from the aluminum foil sheet at the bottom end of the reducing pipe, and the support plate part also extends out of the reducing pipe accordingly, and the powder slides outwards through the gaps between the support plate parts.

[0017] The beneficial effects of the present utility model are:

[0018] The structure of the utility model is reasonably designed. It mainly consists of a lower cover, an upper cover, an inner powder storage cover, an inner plug and an aluminum foil sheet. On the one hand, the lower cover, the inner powder storage cover, the inner plug and the aluminum foil sheet jointly enclose a powder storage area, which can reliably seal the powder and has a good quality preservation effect. By opening the upper cover and pressing the inner powder storage cover to break the aluminum foil sheet, the powder in the inner powder storage cover can flow out freely. In this way, it is convenient for one-handed powder release operation. On the other hand, since an opening is also provided at the upper end of the inner powder storage cover, after the lower cover and the inner powder storage cover are assembled on the bottle body, the powder can be directly filled into the inner powder storage cover.

[0019] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. Brief Description of the Drawings
