Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to a sealed welded combined bottom-penetrating solid-liquid separation bottle cap. Background Art

[0002] The common point of functional bottle caps is that they are used to package powdered, granular solid beverages, honey or concentrated liquid beverages, and then combined with bottled water. They can also be packaged and sold separately. When in use, the top of the cap is pressed or twisted, and the piercing piece inside the cap breaks through the sealed bottom of the lower cap. The powdered, solid beverage, honey or concentrated liquid beverage in the bottle cap dissolves with the water in the bottle for drinking. In the design of the cap body, in addition to ensuring the rationality of the design of the upper and lower caps, it is more important to save effort when pressing and use it.

[0003] There are other combinations of push-down top-penetrating functional bottle caps, but their disadvantage is that they are not tightly sealed after assembly. The bottle cap is affected by temperature, expands when hot and contracts when cold, and the assembly position will be deformed. Outside air enters the bottle cap through the deformation gap, causing the product in the cap to be contaminated and deteriorate. The sealing base and the cap body are not injection molded at one time, and are heat-sealed with aluminum foil after filling. The plastic parts are immersed in the water bottle for a long time after being exposed to high temperature and in contact with water, which poses a food safety risk. When the water in the bottle freezes and expands in low temperature in winter, the aluminum foil is likely to be broken by the ice, causing the solid beverage in the bottle cap to leak. The sealing bottom is not tightly sealed, which may cause the product in the bottle cap to deteriorate. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a sealed welded combined bottom top-through solid-liquid separation bottle cap, which solves the problems raised in the above background technology. To achieve the above purpose, the utility model is implemented through the following technical solutions: a sealed welded combined bottom top-through solid-liquid separation bottle cap, including an outer cover, an upper cover and a lower cover;

[0005] The outer cover material is a soft elastic material, and a top column is provided inside the outer cover for supporting the upper cover. The outer cover and the inner top column are integrally injection-molded. When in use, the outer cover top is tapped lightly, and the outer cover is deformed by force, and the inner top column pushes the upper cover top downward, so that the upper cover is deformed and the upper cover inner top-piercing piece pushes open the conical sealing bottom of the lower cover; the upper cover includes a raised flexible cover top, and the side of the raised flexible cover top is equipped with a cover edge, and the bottom of the raised flexible cover top is equipped with a cover inner top-piercing piece, and the lower cover includes a lower cover top outer edge combining position, and the bottom of the lower cover top outer edge combining position is equipped with a lower cover conical sealing bottom, and a fracture is opened between the lower cover conical sealing bottoms.

[0006] Preferably, the outer cover is assembled at the outer side of the upper cover and the lower cover. A top cone column is provided inside the outer cover for supporting the upper cover. The outer cover and the inner top column are integrally injection molded. When in use, the top of the outer cover is tapped lightly.

[0007] Preferably, the raised flexible cover top and the bottom of the upper cover edge have ring-shaped welding ribs, and the top penetration piece inside the cover is integrally injection-molded, and the raised flexible cover top is elastic.

[0008] Preferably, a ring-shaped fixing position is designed on the outer edge of the top of the lower cover corresponding to the upper cover, which is used to fix the upper and lower covers after they are combined.

[0009] Preferably, the bottom of the upper cover edge has a ring-shaped welding rib and the upper cover ring-shaped welding rib has a concave positioning ring welding position corresponding to the outer edge of the top of the lower cover through ultrasonic welding.

[0010] Preferably, the lower cover is concave and is integrally injection molded, and the interior of the lower cover is filled with powdered solid beverage, granular solid beverage, honey or concentrated liquid beverage.

[0011] Preferably, the inner side of the outer cover and the outer side of the lower cover are provided with matching teeth.

[0012] The utility model provides a sealed welded assembly bottom-penetrating solid-liquid separation bottle cap, which has the following beneficial effects:

[0013] The sealed welded combined bottom-penetrating solid-liquid separation bottle cap is used for bottles with standard bottle openings or other bottles with non-standard openings. The conical sealing bottom of the lower cover can be easily disconnected by using a top-penetrating piece inside the cap to push open the conical sealing bottom of the lower cover. That is, the outer cover, upper cover and lower cover can be combined by gently tapping the top of the outer cover with hands, so that the top cone column inside the outer cover pushes down the upper cover, and the inner-cap top-penetrating piece inside the upper cover pushes open the conical sealing bottom of the lower cover. This method is labor-saving and light. Alternatively, the outer cover can be omitted and the upper cover and lower cover can be combined. The top of the upper cover can be pressed by hands, so that the inner-cap top-penetrating piece inside the upper cover pushes open the conical sealing bottom of the lower cover. This method is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
