Technical field

A kind of component that the utility model relates to be open for sealing container, and in particular to bottle with solid-liquid separation function Lid.

Background technique

The existing container for containing the mixing liquids such as beverage, oral solution, health care product is usually by container body and bottle cap two Part forms, the mixing liquids such as beverage, oral solution, health care product being equipped in container body be usually in factory floor with solvent and Additive is deployed, and consumer opens bottle cap and can be used, but limited shelf life and apt to deteriorate, therefore some has storage Object space comes into being to store the bottle cap of first wife's material, and solid first wife was both expected the storage such as component such as solid beverage, drug, additive There are in the storage space in bottle cap, separately it is kept separately with the intracorporal water of bottle or other liquid instant again when needing to drink Mixing.Existing solid-liquid separating bottle cap mostly uses greatly " penetration type " structure, i.e., storage space and thorn are provided in bottle cap body Wear part, the lower part of bottle cap is provided with sealing film, such as sealing aluminium foil, sealed plastic film tearable membrane, as patent CN207791583U, CN207157888U, CN206857319U etc., although such " penetration type " structure can substantially meet the demand of separation of solid and liquid, Be there are still some problems, such as: 1. sealing aluminium foils, sealed plastic film tearable membrane pierce through and rock bottle body in pierced part and mix During closing solid and liquid, membrane material is easy partially or completely to fall off from bottle cap, falls into drink, both influences drinking mouth Sense also results in unclean unhygienic；2. sealing the tearable membranes such as aluminium foil, sealed plastic film may not during transporting and selling It is careful to be pierced, cause accidentally to mix, generates financial losses.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of bottle with solid-liquid separation function Lid, the bottle cap do not use tearable membrane and piercing member structure, not will lead to tearable membrane and shed into drink.

In order to achieve the above object, the utility model adopts the following technical solution:

A kind of bottle cap with solid-liquid separation function, the bottle cap include flexible pressing component, storage space side wall and close It blockades every bottom cover, the flexible pressing component is set to the top of storage space side wall, and the hermetic barrier bottom cover is set to storage The bottom of object space side wall, the space that the flexible pressing component, storage space side wall and hermetic barrier bottom cover surround are storing Space；Push rod is provided in the storage space, the push rod is under the promotion of flexible pressing component by the hermetic barrier bottom Lid completely pushes away the bottom of storage space, and the hermetic barrier bottom cover is integrally attached at the bottom for pusheding away from storage space Push rod.

Further, when the hermetic barrier bottom cover is assembled to the bottom of storage space side wall, the hermetic barrier bottom cover It is fixedly connected with push rod bottom, so that hermetic barrier bottom cover is integrally attached to push rod when pusheding away from storage space.

Further, the bottom of the push rod with hermetic barrier bottom cover is detachable is fixedly connected.

Further, the top center of the hermetic barrier bottom cover is provided with mounting portion, and the top of the mounting portion is downward Recess forms the first recessed portion, and the first insertion section straight up is provided in the middle part of first recessed portion；The push rod Bottom is the second insertion section, is provided with the second recessed portion being recessed upwards in the middle part of second insertion section；First insertion section It is plugged in the second recessed portion, second insertion section is plugged in the first recessed portion.

Further, when the hermetic barrier bottom cover is set to the bottom of storage space side wall, the hermetic barrier bottom cover Radial pressure is generated to the bottom inside of storage space side wall, so that the side wall of the hermetic barrier bottom cover and storage space side wall Bottom inside abut to form sealing.

Further, the bottom of the hermetic barrier bottom cover and storage space side wall is realized using the encapsulating method of self-sealing Sealing, the hermetic barrier bottom cover includes sealing, and the outer wall of the sealing is vertical, the sealing and storage space side wall Bottom interference fit.

Further, the bottom of the hermetic barrier bottom cover and storage space side wall is realized using the encapsulating method of expanding Sealing, the hermetic barrier bottom cover includes sealing, the outer wall inclination of the sealing, the shape of the bottom outer wall of the sealing Shape, size are consistent with the shape of storage space bottom, size, the distance of the outer wall of sealing to hermetic barrier bottom cover center from Bottom is gradually increased to top, and the outer wall of sealing and the bottom of storage space side wall are made under the reaction force of extrusion deformation Inside, which is formed, to abut.

Further, the bottle cap includes outer cover, and the top of the outer cover is connect with the outside of storage space side wall.

Further, the protection portion to form enclosing wall type, the protection portion are upwardly extended at the top of the storage space side wall Height be higher than flexible pressing component top height.

Further, the bottle cap further includes flip lid cap, and the flip lid cap is set to the top of outer cover, the flip lid cap The height at top is higher than the height of flexible pressing component top.

Compared with prior art, the utility model has the following beneficial effects: the utility model with solid-liquid separation function Bottle cap includes flexible pressing component, storage space side wall and hermetic barrier bottom cover, wherein flexible pressing component is set to storing sky Between side wall top, hermetic barrier bottom cover is set to the bottom of storage space side wall, flexible pressing component, storage space side wall and The space that hermetic barrier bottom cover surrounds is storage space；It is provided with push rod in storage space, when pressing mixing, presses flexible pressing Hermetic barrier bottom cover is completely pushed away the bottom of storage space, sealing resistance by component, push rod under the promotion of flexible pressing component Push rod is integrally attached to when bottom cover is in the bottom for pusheding away from storage space.Since hermetic barrier bottom cover is completely pushed away storing It the bottom of space wall and is fixedly connected with push rod after pusheding away from, therefore hermetic barrier bottom cover will not fall into bottle, Bu Huiying Ring drink mouthfeel will not cause it is unclean unhygienic.
