Description

The convenient and healthy beverage closure of air hermetic

The utility model relates to a kind of beverage closure, the convenient and healthy beverage closure of particularly a kind of air hermetic.

To bottled drink sealing after sterilization, be that the normal temperature of beverage is guaranteed the quality and hygienic basic demand, the repeatedly unlatching of bottled drink is drunk, repeatedly sealing, antipollution requirement have been proposed again.A kind of convenient and healthy beverage closure of adding a cover on bottled drink on the present market, made of plastic, it has the lid that screws with bottleneck, the beverage inner flow passage that hollow is arranged in the lid, the outer cutting ferrule suction nozzle of lid, suction nozzle lid is relatively done displacement, and has the beverage outer flow passage hole that misplaces with the outlet of lid inner flow passage.The pull-up suction nozzle forms the runner between suction nozzle and lid end face, makes inside and outside runner unimpeded, depress suction nozzle, the suction nozzle top cover can cover the inner flow passage outlet of lid end face again, eliminates intermediate flow channel, makes beverage be difficult for pouring out, certainly also add cover on the suction nozzle and put the dirt cap, the beverage closure of this structure is not because the junction of lid and bottleneck, lid and suction nozzle all has sealing, therefore, and after the beverage bottle can, bottleneck must be sealed up membrana oralis, just can add lid.Certainly, when drinking, must screw off lid earlier, tear off to seal and to add lid behind the film once more and implement to drink operation.This is no matter to the filled drink operation with drink, all brought inconvenience, secondly, when tear off seal film after, especially in the several times of drinking process, polyester beverage bottle locates to be subjected to external force to push at pocket, handbag etc., not only may suck the outer dirt of bottle, comprise bacterium in the air, influence hygienicly, also can make bottle interior beverage through the gap seepage.

The purpose of this utility model is to provide a kind of air hermetic convenient and healthy beverage closure, can repeatedly repeat to drink, seal after bottle is opened again directly to the sealing of the beverage bottle after the can, makes bottled drink carry, drink convenience, safety, health.

Task of the present utility model is finished like this: the convenient and healthy beverage closure of air hermetic made of plastic, comprise screw with bottleneck and be converx lid, be enclosed within the suction nozzle that also can make relative displacement on the lid, with cover suction nozzle and be positioned at dust cap on the lid, it is characterized in that: the interior shoulder at lid middle part is provided with a circle seal groove that embeds for bottleneck, a barrel-contoured convex mouth is arranged at the top of lid, and the center of lid is the beverage inner flow passage of hollow; The top cover bottom surface of suction nozzle is provided with and can embeds or move back a circle seal groove that pulls out to convex mouth on the lid, and the top cover of suction nozzle has a plurality of holes of making the beverage outer flow passage in the seal groove outside; Lid outer wall and suction nozzle inwall are provided with the thread that screws mutually; The seal groove of described lid and suction nozzle is three elasticity stuck points of convex mouth leak free on all having bottleneck, lid on the cross section.

Seal groove cross section on above-mentioned lid and the suction nozzle all is M shape, forms three elasticity stuck points.

Because the convenient and healthy beverage closure of air hermetic has adopted seal groove in the said structure, enforcement is to the sealing of three elasticity stuck points of convex mouth on bottleneck, the lid, and suction nozzle to convex mouth on the lid repeat embed, move back and pull out structure, reality this structure beverage closure directly seal bottleneck, can repeatedly open and close the sealing drink outer flow passage easily, the health, the safe requirement that adapt to several times of drinking and guarantee beverage in the bottle had both been omitted the bottle mouth sealing film, had made things convenient for beverage filling processing again and had drunk operation.

Below with accompanying drawing in conjunction with the embodiments to concrete structure of the present utility model, be further described again:

The cutaway view of the convenient and healthy beverage closure of air hermetic that Fig. 1 provides for the utility model.

Fig. 2 is drinking the cutaway view of attitude for Fig. 1 structure beverage closure.

As shown in the figure, the convenient and healthy beverage closure of the air hermetic that plastics are made comprises the convex lid 2 that screws with beverage bottle 1 bottleneck, is enclosed within the suction nozzle 6 on lid top and covers suction nozzle, and be positioned at the dust cap 7 on the lid.The inwall of lid 2 bottoms and bottleneck are all realized screwing mutually with thread 16.Shoulder is provided with a circle seal groove 3 in the lid middle part that the bottleneck end props up.A barrel-contoured convex mouth 11 is arranged at lid top.The center of lid is a funnelform beverage inner flow passage 5.Also there is a circle seal groove bottom surface of suction nozzle top cover.The outside of sealing groove has a plurality of holes 8 of making the beverage outer flow passage.The suction nozzle downside cooperates with lid top, except realize the qualification of relative shift with spacing protruding circle 13 of suction nozzle and the spacing protruding circle 12 of lid, prevent that suction nozzle from deviating from outside the lid, also have and supply the suction nozzle swivel feeding or move back the thread 14 that pulls out at spacing protruding circle, this thread can be three-way thread, so that rotation is steady and sliding is good, guarantee that driving fit is steady, open and close rotation degree of tightness appropriateness.The cross section of the seal ring in the above-mentioned lid 2 on shoulder and the suction nozzle 6 top cover bottom surfaces all is M shape, forms back seal point 9 and both sides sealing point 10 shown in the suction nozzle section, totally three point elasticity contact seals.Through swivel feeding, seal groove both sides sealing point 10 is subjected to pushing of convex mouth 11 on the lid earlier with suction nozzle, and the extruding that makes back seal point 9 be subjected to convex mouth upper surface on the lid at last ends.Back seal 9 pressurizeds, both sides sealing point 10 is tightened up to the center, guarantee that cap seal reaches height air tight closure attitude, and in rotation extruding sliding process, the cross section is the contact seal mode of M shape bikini, can also do the comformability elastic deformation with the convex mouth side view that embeds seal groove, therefore, have self aligning preferably and self-locking seal.The seal ring 3 of shoulder is also herewith managed with the insert seal of bottleneck in the lid, and this place need not seal film envelope bottleneck.Dust cap 7 covers suction nozzle 6 its downsides, screws the location with the thread 4 of lid middle part boss side surfaces.Take in the lid 2 upward and the seal groove on the suction nozzle 6 top cover bottom surfaces in order to import easily, bottleneck 15 and convex mouth 11 can be made into trapezoidal.When drinking the bottled drink of this structure beverage closure, dust cap 7 as long as outward winding, unscrew suction nozzle 6 again to the resistance gear that is subjected to spacing protruding circle 12,13, convex mouth 11 promptly withdraws from the M shape seal groove on the suction nozzle, the beverage inner flow passage 5 at lid center, promptly by the suction nozzle inner chamber, link up with the pory beverage outer flow passage 8 of suction nozzle side, beverage can be poured out in bottle.Otherwise, screwing in suction nozzle to convex mouth 11 when being embedded into, being pressed in the M shape seal groove of suction nozzle 6, beverage bottle is hermetically sealed again again, but spiral cover dust cap 6 again.So repeat, can guarantee health, the safety of several times of drinking, finish off the Bottle and closure after the beverage, still can be by user's filled drink and utilizing again voluntarily.
