Abstract

The utility model relates to a bottle cover containing instant particles for preparing beverage, comprising a bottle cover (1). The middle of the bottle cap (1) is provided with a piston sleeve (2) whose lower part is provided with a closing cover (3); a piston (5) whose lower part opening is provided with a storage chamber (4) is arranged in the piston bush (2); the upper part of the piston (5) is provided with a pressing shank (6); an annular seal ring (7) is arranged between the piston (5) and the piston bush (2); a support ring (8) is arranged between the pressing shank (6) and the bottle cap (1). When using, only the support ring is removed and the piston can be pressed easily. The bottle cover not only solves the seal problem for a storage chamber but also solves the problem of difficult pressing. The utility model has the advantages of simpler structure, lower cost, good sealing effect and convenient use and operation. The utility model can be used as bottle covers for various bottling beverages.

Description

A kind of bottle cap that instant beverage is housed

The utility model relates to a kind of bottle cap, particularly a kind of bottle cap that instant beverage is housed.

The bottle cap that has instant beverage at present is a lot, all is to be applied in the mineral water drink usually.Implementation is to be added with the storage chamber that can store instant beverage on conventional bottle cap, when drinking, bottle cap is operated making instant beverage fall into bottle to be mixed with required beverage as required.But the structure of these bottle caps is all unreasonable, the general sealing problem of poor that all has storage chamber, in Here it is the existing design, moisture content can infiltrate to storage chamber between the inwall of piston bush and piston outer wall, make bottle cap after encapsulation, can not adopt the method sterilization of immersion, the halfway situation of sterilization often occurs.And because sealing is bad, the instant beverage of dry powder shape in the storage chamber is subject to the influence of airborne moisture content and makes moist and harden or go mouldy, the shelf-life of dry powder beverage be difficult to accomplish with bottle in the shelf-life coupling of liquid.The bottle cap of existing besides various band beverages, in order to make good sealing effect as far as possible, always reduce the gap between the faying face of storage chamber and bottle cap, this way had not both fundamentally solved sealing problem as far as possible, caused great inconvenience in use for again the user.

The purpose of this utility model is: provide a kind of structure simpler, cost of manufacture is lower, good seal performance, the bottle cap that instant beverage is housed easy to use.It is to have the bottle cap of piston bush and be placed on the piston that has storage chamber in the piston bush by one to constitute, and is added with seal ring between piston and piston bush, between the handle of piston and bottle cap bracing ring is arranged.

Formation of the present utility model: it comprises bottle cap (1), in the middle of the bottle cap (1) piston bush (2) is arranged, and a capping (3) is arranged at the bottom of piston bush (2); The piston (5) of one bottom open band storage chamber (4) is arranged in the piston bush (2), and handle (6) is arranged at the top of piston (5); Be characterized in: between the inwall of the outer wall of piston (5) and piston bush (2) grommet type seals (7) is arranged; Between handle (6) and the bottle cap (1) bracing ring (8) is arranged.

Compared with the prior art, the utility model is owing to be provided with grommet type seals between piston outer wall and piston bush inwall, is provided with a bracing ring between the handle of piston and bottle cap; During use,, just can easily press lower piston as long as remove bracing ring.Both solved the sealing problem of storage chamber, and solved piston again and be difficult to press problem.It is simpler that it has structure, and cost of manufacture is lower, and good sealing effect uses convenience operation.The bottle cap that can be used as various bottled drinks uses.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is done and to be described in further detail.

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the utility model piston portion structural representation.

Accompanying drawing 3 is the utility model piston bush and bottle cap part-structure scheme drawing.

Embodiment: what accompanying drawing 1 was represented is a kind of version of the present utility model, and its formation comprises plastic bottle closure (1), in the centre of bottle cap (1) a plastic piston cover (2) is arranged, the capping (3) that the useful aluminium foil in bottom of piston bush (2) is done; Have a bottom to have the plastic piston of angle or sawtooth mouth (5) in the piston bush (2), the centre of piston (5) is that a cavity is storage chamber (4), and the top of piston (5) is handle (6); Between the inwall of the outer wall of piston (5) and piston bush (2), grommet type seals (7) is housed; Between handle (6) and the bottle cap (1) bracing ring (8) is arranged.The effect of bracing ring (8) is to stop pressing of handle (6), in the time of need pressing handle (6), tears bracing ring (8) by draw ring and can press.Shown in accompanying drawing 2 and accompanying drawing 3, bracing ring (8) adopts an end to be fixed on the handle (6) in this example, and the other end is installed by the mode that hasp and bottle cap (1) connect.Certainly, also can adopt alternate manner that bracing ring (8) is fixed between handle (6) and the bottle cap (1).

The utility model in use, if do not need in bottle to add instant beverage, the bottle cap (1) of directly outwarding winding gets final product.In bottle, add instant beverage if desired, then earlier remove bracing ring (8) by draw ring, press handle (6) then downwards, piston (5) is moved down, the angle of the lower open end of piston (5) or sawtooth puncture the capping (3) that masking foil is made, the dry powder shape in the storage chamber (4) of piston (5) or the instant beverage of concentrated sap-shape just fall into bottle, obtain various mineral water beverages after the mixing, and the bottle cap of outwarding winding again (1) is promptly drinkable.The grommet type seals (7) that is provided with between the inwall of the outer wall of piston (5) and piston bush (2), can play stop moisture content along between the inwall of piston bush (2) and piston (5) outer wall to the effect of storage chamber (4) infiltration.Can prevent the hardening, go mouldy of instant beverage in the storage chamber (4) effectively, improve the shelf-life of instant beverage in the storage chamber (4).

Claims

1, a kind of bottle cap that instant beverage is housed comprises bottle cap (1), in the middle of the bottle cap (1) piston bush (2) is arranged, and a capping (3) is arranged at the bottom of piston bush (2); The piston (5) of one bottom open band storage chamber (4) is arranged in the piston bush (2), and handle (6) is arranged at the top of piston (5); It is characterized in that: between the inwall of the outer wall of piston (5) and piston bush (2) grommet type seals (7) is arranged; Between handle (6) and the bottle cap (1) bracing ring (8) is arranged.
