The utility model comprises an outer cap and an inner cap, the utility model is characterized in that a rotary screw thread is provided at the inner side of the outer cap connected with a outer knob of a sealing surface, a raw of seals rotated and disconnected in one time are arranged at the lower end of the outer cap, the inner cap is inserted in the sealing surface, a circular hole connected with the outlet of a water dispenser is arranged in the middle. Compared with the prior art, the utility model has the advantages of the anti-fake performance of a small water bottle, convenience for carrying, guaranteed expiration date, and being operated on the existing 5 gallon water dispenser, etc.

Description

Bottled water bottleneck Bottle cap structure

Technical field

The utility model has related to a kind of bottle cap of potable water, is specially adapted to the bottle cap of 2 gallons of bottled waters.

Background technology

In the prior art, drum water is accepted by increasing people at present, the quality of drum water is also paid close attention to by increasing people, particularly along with the exposure of news media to small-scale production factory Heisui River bucket, famous brand name water is palmed off, and green paint or the like problem appears in water-butt, makes more people slowly forbidding to water-butt again.End is got up, and mainly is following reason: 1, drum water is owing to adopt returnable bottle, and the cleaning problem of bottle is difficult to solve, and the shelf-life of drum water is reduced.Also limit simultaneously very big that the market of drum water can not do, caused certain difficulty for the expansion of producer.2, the cost of drum water bucket is too high, has also limited the expansion in market.3, drum water is false proof fairly simple, so be easy to be palmed off, makes producer suffer unrighted wrong.4, drum water can only use in family, is inconvenient to carry go on a tour.Though be convenient for carrying 1.5 rise following bottle water, and compare health, on the high side, also limited people's use.

The purpose of this utility model is that a kind of deficiency that overcomes above-mentioned drum water will be provided, and its bucket volume is fit to the 0.5-3 gallon, and bottle cap that again can disposable bucket.

Technical scheme

Later-model purpose realizes by the following technical solutions: the utility model comprises enclosing cover and inner cap, it is characterized in that the rotation screw thread being arranged with the outer turn-knob bonded assembly enclosing cover inboard of bottleneck, the enclosing cover lower end has a row can disposable rotation is open circuited to seal, inner cap inserts in the bottleneck, has one can connect the circular hole that water dispenser exports in the middle of it.

The sideway swivel screw thread is constituted by multi-turn tilted circle groove in the enclosing cover of the present utility model, and it is end closure and the clamping of bottleneck convex-concave down, and the junction has one, and arrange can the open circuited tooth of disposable rotation.Described cover top portion is inboard to have a circle circular seal groove with inner cap potted line contact position, is provided with a seal ring in the seal groove.The excircle of described inner cap inserts in the bottleneck, and it is that end has bottleneck upper end, a convex platform position; The interior circular hole of inner cap is settled a bottle stopper.The inner cap excircle is provided with linear sealing or face sealing, and the cross-sectional plane of inner cap is spill.

The utility model compared with prior art have flask antifalsification, easy to carry, guarantee the shelf-life, advantage such as can on existing 5 gallons of water dispensers, use again.

Specific embodiment

Below in conjunction with description of drawings the utility model is described in further detail: as shown in Figure 1, the utility model is equipped with the bottleneck lid that comprises enclosing cover 2 and inner cap 3 on the bottleneck 1 of drinking-water bottle.And in bottleneck 1 outside the inboard of turn-knob bonded assembly enclosing cover 2 rotation screw thread 4 is arranged, screw connection by relative rotation screw thread fit on its rotation screw thread 4 and the bottleneck 1.Enclosing cover 2 lower ends have one the circle can be owing to after the disposable rotation, just fully open circuitedly seal 5, in wanting drink bottle during water, revolve alarmed and panicky bottle enclosing cover 2, because the lower end of enclosing cover 2 has a circle to engage with the groove of bottleneck 1, the displacement when revolving on the enclosing cover 25 is twisted into two parts sealing on the enclosing cover 2, could open enclosing cover 2, the water in the drink bottle.The inboard that inner cap of the present utility model 3 inserts bottlenecks 1, in the middle of it inner cap 3 in the middle of the place have one can with the water dispenser outlet peg graft circular hole 6.The cross-sectional plane of inner cap 3 is spill, in the circular hole 6 in the middle of it columniform bottle stopper 7 is arranged.When being connected use with water dispenser, circular hole 6 is inserted in the inlet opening of water dispenser, supports and opens cylindrical bottle stopper 7, and water just flows in the water dispenser in the bottle.As shown in Figure 2, sideway swivel screw threads 4 are by multi-turn tilted circle groove 8 and is constituted in the enclosing cover of the present utility model 2, and it descends end closure 5 and bottleneck 1 convex-concave clamping, and the junction has one, and enclose can the open circuited tooth 10 of disposable rotation.Cover top portion is inboard to have a circle circular seal groove 9 with inner cap potted line contact position, is provided with a seal ring 13 in the seal groove 9.As shown in Figure 3, the excircle 11 of described inner cap 3 inserts bottleneck 1 inboard, and its upper end has a convex platform 12 to support the upper end of position bottleneck 1, makes inner cap 3 not exclusively insert bottleneck 1 inboard, and falls in the bottle.The interior circular hole 6 of inner cap 3 is a post shapes, has laid a bottle stopper 7 in the middle of it, props up bottleneck 1, does not allow water flow out.The inner cap excircle is provided with linear sealing or face sealing 14.As shown in Figure 4, being the utility model partly assembles the signal state with bottleneck after water dispenser is connected.
