Description

The security closure of bottle class

The present invention relates to the security closure of bottle class.

Although existing this class capping has many-sided advantage, a generally acknowledged shortcoming that is outstanding is so far arranged.

In fact, someone is after opening bottle without approval, and he can be patient and install safe bar again dexterously and make it to set back, thereby makes afterwards buyer think that this bottle never breaks seal by mistake.

Problem to be solved by this invention is to design the capping that a kind of its 26S Proteasome Structure and Function feature can address the above problem specially.

Security closure based on bottle class of the present invention comprises: one topples over part; One cylindrical sleeve, this sleeve have one be used for fixing this topple over the inward flange of part; One cap; One cap with topple over being threaded between the part and be used for screwing on and screwing off cap; One safety strap, this safety strap comprise that one is connected to ring bar on the cap by a line of weakness; Done external tooth on the cylindrical sleeve, and ring is done when screwing off this cap first against the relative internal tooth of this tooth, it is characterized in that this safety strap is separated into two parts at least on the bar, external tooth is formed on the dimple that tiltedly shoulder defines of one in the cylindrical sleeve.

The major advantage of capping of the present invention is that because safety strap can't be loaded onto again, people's a glance just can find out whether bottle is opened without approval.Another advantage of capping of the present invention is simple in structure, and this product for Quantity production is one of most important advantage.

From following in conjunction with the accompanying drawings to knowing the further feature and advantage of finding out capping of the present invention the explanation of the present invention's one nonrestrictive preferred embodiment.In the accompanying drawing:

Fig. 1 is the part sectional view of capping of the present invention, and some parts wherein separately;

Fig. 2 is a section-drawing of Fig. 1 capping;

Fig. 3 expresses the details of Fig. 2 capping for to cut open the section-drawing of getting along III among Fig. 2-III line;

Fig. 4 is sealed on view under another mode of operation for Fig. 1.

Referring to each accompanying drawing, label 1 expression one is used for unillustrated one bottle security closure, and this bottle can be used to the famous and precious drinks of splendid attire especially.

Capping 1 comprises topples over part 2, cylindrical sleeve 3, cap 4 and safety strap 5, and they link together coaxially along axis X-X.

Toppling over part 2 inside has a seal valve 6 that prevents again filling bottle, and it also comprises an outward flange 7 and outside thread 8.

Have one on the top 9 of cylindrical sleeve 3 with the inward flange 10 of flange 7 overlap joint with by the oblique outer dimple that forms of shoulder 3a.Cylindrical sleeve 3 has annular epipharynx 12 and some axial projections 13, they respectively with bottle on a groove and some conduits engagements, thereby make this sleeve be fastened on that bottle is gone up and can't be relatively bottle move axially and rotate.

Sleeve 3 falls back on the flange 10 that is overlapped on the flange 7.And be fixed on the bottle toppling over part 2 in the axial direction.Connect by the tooth on their fronts 14 between flange 7 and the flange 10 and make and topple over body 2 and can't rotate relative to cylindrical sleeve 3, thus also just can't be relative to bottle rotating.

On cap 4 outside faces annular knurl 15 is arranged, screw thread 16 is arranged on the inside face, this screw thread 16 forms with outside thread 8 and is threaded 17, screws off thereby can be screwed into this cap on the oblique tube or from it on demand.

Particularly, cap 4 comprises that an interior cap 18 and is enclosed within the outer cap 19 on the interior cap 18.

The interior cap 18 of negative thread 16 being arranged on it and have on it has connecting device 20 that interior cap and outer cap are linked together between outer cap 19 of outer knurled 15.

Particularly, lasso 21 in this connecting device comprises on the cap outside face and the annular projection 22 on the outer cap inside face, they are snapping and form and connect 23 up and down, thereby in the axial direction interior cap and outer cap is tightened together.

For interior cap and outer cap are fixed into and can't relatively rotate, the axial teeth groove 24 on the interior cap outside face is connected 16 with axial teeth groove 25 formation teeth groove on the outer cap inside face.

Teeth groove

24 and 25 has pointed leading-in

end

24a and 25a respectively, thereby can be by on the cap in cap is directed to outside the predetermined angular pitch handle when assembling.

Cap 18 is connected on the cylindrical sleeve 3 by a line of weakness 27 in should be noted that, this line of weakness goes out with graduating with cutter at interior cap and the integrally molded back of sleeve.

Safety strap 5 usefulness one ring bar 28 is made, and it is connected with outer cap 18 by a line of weakness 29.

Ring bar 28 roughly is contained in the dimple 11 and with oblique shoulder 3a and roughly connects.

Ring bar 28 is divided into

semi-circular portion

30 and 31 independently identical on two structures by two at diametrically opposite otch 32.

Line of weakness 29 and two otch 32 cap outside go out with graduating with cutter with the integrally molded back of ring bar.

Being shaped on many external tooths 33 on the dimple 11 of cylindrical sleeve 3, is 24 points in the embodiment shown.Being shaped on many points 34 on ring bar 28 inside faces, is 12 points in the embodiment shown, they when screwing off this cap first can with tooth 33 against.

Tooth 33 and relative tooth 34 insert with 25 the predetermined cooresponding predetermined pitch criss-cross of pitch that is connected to be connected 26 teeth groove 24 with teeth groove during assembling.

The cross-sectional plane of tooth 33 and relative tooth 34 is for having the serration of surperficial 33a and 34a respectively.From screwing off the direction of this cap, the surperficial 33a of tooth 33 recedes with angle A, and the surperficial 34a of relative tooth 34 turns forward with angle B.

The angle of oblique angle A and B is chosen to be 5 °-25 °, is 15 ° in the embodiment shown.

Parts that capping of the present invention becomes can dispose separately with its each component assembly and installing on one bottle.

When screwing off cap 4 first, at first in line of weakness 27 between cap and the cylindrical sleeve torn, continue then to screw off cap 4 up to relative tooth 34 face-to-face against tooth 37.Cylindrical sleeve stops further swivel becket bar 28 like this.If continue firmly to screw off cap 4, weak 29 are promptly torn.At this moment, ring bar 28 breaks away from outer cap 19 and is cleaved into two

parts

30 and 31 that it is divided into.These two parts slide along tiltedly takeing on 3a because of its weight.They leave its initial position forever, because gravity again can't reset.

Because therefore two surface tilt of two relative teeth can prevent following two kinds of situations, a kind of situation is: encircle two

parts

30 and 31 that bar was divided into during line of weakness is not torn and the tooth overlap joint is relative tooth and radially be extrapolated; Another kind of situation is: line of weakness tear but tooth when tightly propping up relative tooth these two

parts

30 and 31 radially by to lira.

Tooth guarantees simultaneously that with the pre-fixed inclination on relative tooth two surfaces two line of weakness all can be torn, and two parts of ring bar can break away from.

The major advantage of capping of the present invention is, because safety belt can't be loaded onto people again A glance just can find out whether bottle is opened without approval.

Another advantage of capping of the present invention is simple in structure, and this is for large-scale production Product be one of most important advantage.

Certainly, the expert of the art can be in the present invention of appended claim book restriction Protection domain is interior by needing that specifically or for the moment various modifications is made in capping of the present invention.
