Description

A kind of bottle cap

Technical field

This utility model relates to beverage outer wrapper, specifically provides a kind of bottle cap.

Background technology

At present, commercially available liquid bottled drink, is mostly the finished beverage blent, and this kind of beverage exists During storing, selling, transport, need the shelf-life with certain time length, blend to not allow Beverage goes bad, and mostly with the addition of additive of guaranteeing the quality, long-term drink, may cause the health of people in beverage Impact；Therefore some consumers selects to buy packed powder, now cashes and drinks, and reaches to drink the purpose of health, But it is many to convert the instrument that material process is directed to use with, converts material environment and be the most mostly limited in indoor, hold during converting material Easily making beverage suffer secondary pollution, the preservation to be sealed of remaining powder, shortcoming is that process is relatively complicated, no Convenient.

Summary of the invention

The purpose of this utility model is: provides a kind of bottle cap, equipped with the bottled drink of this bottle cap, can make beverage Now cash and drink, drink health, simple to operate, health.

The technical solution of the utility model is: a kind of bottle cap, it is characterised in that: there is inner cap and enclosing cover, outward The inwall of lid is connected with the outer wall thread of inner cap, and the inwall of inner cap is provided with screw thread, solid on the inner bottom surface of inner cap Being connected with material pipe, the lower end of material pipe is provided with material spraying hole, and the upper end of material pipe is provided with through hole, equipped with push rod in through hole, Push rod upper end is connected with the inner bottom surface of enclosing cover, and the shaft of push rod is connected with the hole wall air-tight movable of through hole, push rod Lower surface be fixed with plug, the elongated end activity of plug is pressed on material spraying hole, push rod outer wall with material inside pipe wall Between be provided with cavity.

The screw thread of inner cap inwall is contrary with the thread rotary orientation of interior cover outer wall.

The utility model has the advantages that: during application, the powder of a blending drink is injected in cavity, then to Use after injecting the compressed gas of certain pressure in cavity；When drinking, turn enclosing cover, enclosing cover is with screw thread rotation Rising, make plug separate with material spraying hole, now the powder in cavity sprayed with compressed gas moment, dissolved in bottle In interior drinking water, become beverage, then inner cap of outwarding winding is drunk, simple to operate, health；Thus realize Now cashing the technique effect drunk, powder is sealed storage in cavity, long shelf-life, it is not necessary to adding guarantees the quality adds Add agent, drink health；Inner cap inner thread is the standard thread mouth of bottled water, utilizes inside and outside lid contrary Thread rotary orientation, first can be tightened on the bottle cap being marked with powder on the bottleneck of commercially available pure water or mineral water, more instead Rise enclosing cover to rotation, moment common commercially available plain boiled water can be become the drinking water of various local flavor, color, then outward winding Inner cap is drunk, and versatility is good, easy to use.

Detailed description of the invention

A kind of bottle cap, has inner cap 2 and enclosing cover 1, and the inwall of enclosing cover is connected with the outer wall thread of inner cap, inner cap Inwall be provided with screw thread, the inner bottom surface of inner cap is fixed with material pipe 6, material pipe lower end be provided with material spraying hole 8, The upper end of material pipe is provided with through hole, and equipped with push rod 5 in through hole, push rod upper end is connected with the inner bottom surface of enclosing cover, push rod Shaft be connected by sealing ring 3 air-tight movable with the hole wall of through hole, the lower surface of push rod is fixed with plug 9, The elongated end activity of plug is pressed on material spraying hole, is provided with cavity 4 between push rod outer wall and material inside pipe wall, described Push rod is equivalent to a big piston, and through hole is sealed by big piston, and plug is equivalent to a valve piston, little Material spraying hole is sealed by piston, so that cavity forms a pressure sealing structure.

In said structure, inside and outside lid fit system is following several form: the unscrewing force of enclosing cover is less than inner cap Unscrewing force so that enclosing cover is first outwarded winding, material is converted in release, then inner cap of outwarding winding is drunk, or, in inner cap The screw thread of wall is contrary with the thread rotary orientation of interior cover outer wall, the most counterclockwise rotary outer cover, and enclosing cover is in the promotion of screw thread Under move up, after converting material ejection, then the enclosing cover that turns clockwise, enclosing cover drives inner cap to depart from bottleneck after screwing 11, or, select the screw thread of particular design as conventional on the screw thread between inner cap and enclosing cover, such as medicine bottle The unscrewing type screw thread of pressure down, there is the screw thread of forward and reverse threaded line, there is the threaded line etc. of upper and lower stop Deng；Purpose is all to utilize helicitic texture first to make enclosing cover lifting release convert material, then makes inner cap open to drink, so, No matter use which type of helicitic texture, as long as meeting above-mentioned technique effect, all in protection of the present utility model In the range of.

In order to ensure sealing effectiveness, can be equipped with sealing ring between the inner bottom surface of enclosing cover and the end face of inner cap；For Convenience is docked with other bottleneck, the inner bottom surface of inner cap can fill sealing gasket 12, is used for sealing.

A kind of bottle cap of the present utility model is the bottle cap of a kind of draught head perfusion material powder, solves traditional hook Convert beverage and need to add the shortcoming of additive of guaranteeing the quality, and then achieve people and utilize pre-position in bottle before consumption In lid, green beverage safe to drink made by material of converting with pressure.

This utility model is when fill, and outer cover portion upwards, is first outwarded winding by bottle cap internal orifice, makes material spraying hole open, A certain amount of powder 10 is injected in cavity, then screws on enclosing cover and make plug and material spraying hole gently paste, with sky Air compressor injects gases at high pressure in cavity, and about 1.2～1.6 atmospheric pressure, after injecting gas, outside screwing Lid seals, and completes fill, and during application, bottle cap internal orifice uses downwards most preferably；Also powder and pressure can together be injected Contracting air；A kind of bottle cap of the present utility model also can inject oxygen, can convert out oxygen-rich drink；Described plug For rubber plug or pressure valve head；Powder selects high mesh number powder, can dissolve in water.
