Description

The security closure of bottle

The present invention relates to the closing appliance of liquid container, at an end of bottleneck an axially extended bottleneck of the main body from container is arranged, this device comprises: pouring element, and it has internal cavities and pouring opening, and it is positioned at bottle mouth position and with respect to the coaxial extension of bottleneck; Valve element is arranged in the cavity of pouring element and can moves axially with respect to annular ledge, deceives people to enter to allow liquid to flow out to prevent simultaneously other liquid; Bottle cap is used to open and close pouring opening; And the detouchable sealing arrangement, be used for allowing to open for the first time bottle cap.

That has known the above-mentioned type in the prior art has a leak free closing appliance, and is used in particular for holding the bottle of high-quality liquid or beverage.

An example of prior art is disclosed in open text GB-A-2285623, wherein seal by the cover that covers bottle cap and peripheral part and constitute, peripheral part has the shell-like part, and this shell-like partly is the suitable part of the lower device that extends axially and pouring element is fixed to the bottleneck top of bottleneck.

The seal closure of describing in the above-mentioned file has: the first circumference weakened line, and it is positioned near the bottle cap; Second weakened line, it also is provided with along circumference, and is positioned near the end of shell-like part; And horizontal weakened line, it connects two circumferences.Except x wire, circumference also comprises the groove of the material thickness extension of passing cover, and these grooves are spaced apart by connecting bridge, the result, and the visible surface of cover is discontinuous.

For this reason, be not suitable on the existing cover having across the decoration of weakened line uniformly extension or the mark or the otch of printing usually, so that the evidence that does not have Kaifeng to be provided.

And in above-mentioned prior art, cover is connected to the neck of container, and the auxiliary element that inserts between the inside face of neck and shell-like part causes enclosed construction very complicated and expensive simultaneously.

Therefore, the objective of the invention is to, in the field of the closing appliance of the liquid container (especially bottle) of the above-mentioned type, provide a kind of seal closure, even this surface does not have discontinuous part in the zone of weakened line and tear line yet with big visible surface.

Another object of the present invention is to provide a kind of closing appliance, and it is very effective from the view of security, and both economical.

Above-mentioned these purposes realize by having the leak free closing appliance, and its feature is as described in the following claim.

Describe the present invention in further detail referring now to the embodiment shown in the accompanying drawing, accompanying drawing provides nonrestrictive example, wherein:

Fig. 1 is the local longitudinal sectional view according to closing appliance of the present invention,

Fig. 2 is the local longitudinal sectional view of independent seal closure,

Fig. 3 is the view of inside face at the top of cover,

Fig. 4 is the cross sectional drawing along the IV-IV line of Fig. 2,

Fig. 5 is the transparent view of the cover of Fig. 2.

With reference to above-mentioned accompanying drawing, container 2 (especially bottle) has the neck by label 1 expression.The bottle neck 3 of container is provided with pouring element 4,

Pouring element 4 is fixed to neck 1 by a plurality of protruding tongues 5, and the tip of protruding tongue is assembled to the ring-shaped step 6 times of neck 1.The first shell-like part 7 of pouring element by packing ring 8 be fixed on the coaxial position of the X-X axle of container on, another shell-like end 9 of packing ring is crushed in the bottle neck 3.

Packing ring 8 is fixing with spheroid 11 by another open shell-like part 10 and closure elements 12, and spheroid is in known manner as valve element, and closure elements can move in the cavity 13 of toppling over body 4 vertically.

When closure elements 12 during at detent position, the integral ring-shaped edge 14 of 12 pairs of packing rings 8 of closure elements applies power.

The opening 15 of toppling over body 4 seals by covering 16 in the mode of routine, and the annular section 16a of lid 16 is by being threaded on the outside face of toppling over body.

According to the present invention, used sealing to guarantee that this enclosed construction was intact in the enclosed construction before opening for the first time.

Sealing is made of cover, represents with 17 usually.It comprises roof 18 and extends beyond the cover 19 that pouring element 4 is pressed in the zone on the bottleneck 1 from wall 18.

Cover 19 comprises the 19a of first, its with wall 18 adjacent and extend to bottleneck begin locate; The second centre portion 19b; And end portion (terminal band) 19c.

The outside face of whole cover 19 is continuous, and its inside face facing to pouring element 4 and bottleneck 1 has a pair of weakened

line

20 and 21, they are from beginning to extend along the 19a of first of cover with corresponding position, plane, pouring opening 15 place, up to circumference weakened line 22.

Just in time at least one in weakened line below the plane, bottle neck 3 place of bottleneck 1 22 and the weakened

line

20 and 21 intersects.

Weakened line is made of the otch of making in the inside of cover 17, and the degree of depth of otch makes it can't see at outside face.Therefore the surface keeps continuously, and the decoration by uniformly extension on the weakened line below or inscribe and distinguished easily, thereby cover can be proved be sealed in before opening perfect.

With the mode of routine, tear by pullling the zone 23 that the pulling-on piece 24 that is attached thereto will be limited between weakened line 20 and 21.Pulling-on piece constitutes the part of cover 17 roofs.

Pulling-on piece 24 is connected to the edge 18 of lid by at least one cross-over connection part 25, and as shown in Figure 5, pulling-on piece is limited by the groove 20a and the 21a that aim at weakened

line

20 and 21.

Although for simplified structure preferably adopts

groove

20a and 21a, they are not necessary.Position at their places forms and does not appear at exterior weakened

line

20 and 21 at the inside face of the 19a of first, can extend arbitrarily at the base portion of pulling-on piece 24.

Tear zone 23 tubular portion 19a will be separated, remove this tubular portion thereby can further tear along circumference weakened line 22.

After removing the 19a of first, centre portion 19b and end portion 19c are still on bottleneck 1.

Especially, end portion 19c is thinner than centre portion 19b, makes it to be fitted in tightly on the outside face of bottleneck 1, and do not allow to attempt to hold edge 26 cover is not removed from bottleneck.

The existence of first annular projection 27 and second annular projection 29 that forms on the inside face of centre portion 19b also can prevent this removal.First annular projection 27 forms on the inside face of the 19a of first of cover 19, and engages with the step 28 of pouring element 4 from the below.

Second projection engages with the cooresponding step 30 of pouring element 4 from the below.

Except for not breaking a seal and seal cover cap when being fixed on the container provides the remarkable stability, after removing top 19a and uncover, projection 27 that engages with each

step

28 and 30 and 29 combination have also limited the activity of centre portion 19b and end portion 19c.
