TECHNICAL FIELD
[0001] The utility model relates to a kind of packaging containers, in particular to a kind of solid-liquid separation bottle cap. BACKGROUND
[0002] The existing solid-liquid separation bottle is mostly the solid-liquid separation type eye drop bottle disclosed in the patent document with publication number CN222399516U, which is provided with an inner plug and a bottom cover between the bottle cap and the bottle body. When opening, the bottle cap is twisted to make the bottle cap slide downward and press the bottom cover, so that the bottom cover is separated from the inner plug, thereby mixing the solid in the bottom cover with the liquid in the bottle body. However, this bottle cap has a problem. Since the solid is placed in the bottom cover, when the solid is poured into the bottle, the bottom cover will inevitably fall into the bottle at the same time. The bottom cover is easy to contaminate the liquid in the bottle, and the bottom cover floats in the bottle, so the finished product is not beautiful enough. In order to improve the beauty of the finished product, some manufacturers have developed a bottle cap disclosed in the patent document with publication number CN213385588U. The bottle cap uses a separate upper cap, a lower cap, and a sealing cover hung on the lower cap for storing materials. In the sealed state, the sidewall of the storage compartment of the upper cap separates the solid from the liquid. When the upper cap is twisted and pulled out, the solid falls from the storage compartment of the upper cap into the sealing cover and falls into the bottle from the material port on the sidewall of the sealing cover. However, the sealing cover of this structure has the problems of inconvenience in pouring the solid into the bottle, poor mixing effect of the solid and the liquid, and residual solid, which affects the brewing effect.
[0003] In order to solve the above-mentioned problems of the bottle cap, the same applicant of the present application submitted a patent document with application number 2024225940871 at an earlier time. In this application, a tear groove is cut in the bottom of the bottle cap seat. By twisting the cap, the top piece is pushed against the bottom of the bottle cap seat, causing the bottom of the bottle cap seat to break along the tear groove, thereby achieving solid-liquid mixing. However, during production, it is difficult to process the tear groove. If the tear groove is too deep, the brewing material in the bottle cap seat will flow out. If the tear groove is too shallow, the tear part will be difficult to break, and the bottle cap cannot be opened. Furthermore, when filling the brewing material into the bottle cap seat, since the bottle cap seat is a one-piece structure, the upper cap must be twisted and pulled out before the brewing material is filled into the storage cavity from the top of the bottle cap seat. After filling is completed, the bottle cap is assembled. Since the upper cap needs to be tightened for sealing, vigorous twisting may cause the upper cap to push the top piece to pierce the tear groove in the bottom, causing the bottle cap to be pierced during filling. The yield rate during production is low. Therefore, in view of the above-mentioned deficiencies of the bottle cap, it is necessary to design a solid-liquid separation bottle cap that is easy to open and convenient to produce. UTILITY MODEL CONTENTS
[0004] In order to solve the above-mentioned problems of the solid-liquid separation bottle cap, the utility model provides a solid-liquid separation bottle cap convenient to produce.

The lower cap has a storage cavity with openings at both the top and bottom. The top opening component is installed inside the storage cavity. The top of the upper cap is threadedly connected to the top of the lower cap to seal the top of the storage cavity. An axial opening structure is provided between the upper cap and the top opening component. A sealing cap is installed at the lower end of the lower cap. The sealing cap includes a connecting part and a sealing part. The connecting part is fixedly connected to the lower end of the lower cap. The sealing part seals the bottom of the storage cavity. A fracture rib and a connecting rib are provided between the connecting part and the sealing part. When the upper cap is rotated, the top opening component moves down and squeezes the sealing part. The fracture rib breaks, opening the bottom of the storage cavity for material feeding.
[0007] The sealing part is provided with a sealing protrusion along its outer periphery that presses against the inner wall of the storage cavity. After the sealing cover is fastened to the bottom of the lower cover, the sealing protrusion abuts against the inner wall of the storage cavity.
[0008] The inner side of the connecting part is provided with a slot, and the lower cover is provided with a buckle protrusion corresponding to the slot at the connection position with the connecting part. After assembly, the buckle protrusion is engaged in the slot for fixation.

After combination, the anti-rotation strip on the outer side of the top opening component is located within the limiting area.
[0013] The lower part of the top opening member extends out with opening teeth. When the top cover is rotated to open the bottle cap, the top cover pushes the top opening member to move, and the opening teeth press against the sealing cap, causing the fracture rib to break.
[0014] The top of the top opening piece is integrally formed with a mesh sheet, when the brewing material in the storage cavity is tea leaves or the like solid, in order to prevent the brewing material from being poured out together when the mixed liquid is poured, the top of the top opening piece is further provided with a mesh sheet with a plurality of meshes, when the liquid is poured, the liquid flows out through the meshes, and the brewing material is blocked by the mesh sheet due to its large volume, and cannot be poured out together, only the mixed solution is poured, ensuring the purity of the beverage; this filtering method is consistent with the filtering principle of a tea brewing appliance, and selective blocking is realized by using the particle size difference.
[0015] The lower edge of the top opening piece is further provided with a discharge port; when the brewing material in the storage cavity is honey or the like liquid with certain fluidity, the liquid in the storage cavity can flow out from the discharge port, so as to quickly fall into the bottle and mix with the liquid in the bottle to form a mixed solution, accelerate mixing, and improve the mixing effect.
[0016] The beneficial effects of the present application are as follows:
[0017] 1. The lower cover is connected with a sealing cover, a fracture rib and a connecting rib are arranged between the connecting portion and the sealing portion of the sealing cover, when the upper cover is rotated and the top opening piece is pushed to move downward to open the sealing cover, the fracture rib is broken, compared with the integrated bottle cap, the sealing cover in the present application is buckled on the bottom of the lower cover as a separate part, when the brewing material is filled, the filling is performed from the bottom of the lower cover, after filling, the sealing cover is buckled on the lower cover, and the upper cover is always sealed, the bottle cap will not be pierced during filling when assembled, compared with the integrated bottle cap which is filled from the top of the lower cover, the yield rate during production is higher.
