Description

The anti-cheating plug envelope and the improvement thereof of Bottle ﹠ Can

The present invention relates to provides a kind of improved anti-cheating and the easy bottle container of cheating and the assembly set that plug seals of disclosing.The present invention comprises that also one can be used for the improved plug envelope of bottle container neck ring.

The bottle container of standard form has bottle neck on its top, and below bottle neck, round the bottle neck exterior ball is arranged then, and such bottle container abbreviates the standard bottle later on as, and just is called neck ring later on around the outside ball of bottle neck.

There was huge investment in manufacturer for mould and the machine of making this standard jar body and function, such Bottle ﹠ Can was produced millions upon millions of under all size, simultaneously, a kind of requirement that grows with each passing day is: the ability that a kind of improved anti-cheating is provided for the assembly set that has adopted this class standard bottle.In this regard, the inventor etc. had proposed to provide a kind of plug envelope already in its European patent № .0080846, it comprises a cap portion and by the easy crushing device anti-cheating safety strap that is connected of cap portion therewith, and around this band inside be provided with an inner ball, make and will fill in envelope at first when using on the bottle, with on ball can be fitted on the neck ring of bottle, like this, only this band is torn and when cap portion can freely be moved away, above-mentioned plug envelope just can not be from the bottle bottleneck that gets on to turn around to open.

Above-mentioned this being arranged under the general situation is very suitable, but find already, the tolerance of mould is severization inadequately sometimes under following meaning, if promptly with on ball or neck ring or the two oversize, then under the easy crushing device condition of not breaking, will fill in when envelope is applied on the bottle and will meet difficulty.

In recent years, because the appearance of high value product and the danger of mingling, existing more and more many products are to sell with the assembly set form of anti-cheating, and growing demand a kind of simple, than cheapness and actv. plug envelope, to be applied to the neck of standard bottle, no matter and why it abounds with product, make such product to sell with the anti-cheating assembly set that has adopted the standard bottle.Characteristics according to the present invention provide such plug envelope, it comprises that one has the top and hangs the cap portion of skirt and linked the anti-cheating band of hanging on the skirt by easy crushing device, it is characterised in that: this anti-cheating is with being provided with a collection of window that abbreviates later the hole as, be outstanding by this way with acclivitous elasticity tenon inwardly with what go up formation wherein in this, promptly when filling in envelope at first when being applied on the standard bottle neck, the just deflection and being able on the neck ring by bottle of these tenons, then, because their rebound resilience, these tenons are counter its initial position that is bonded to inwardly, makes the last top of this each tenon be configured to the below of neck ring lower surface.

Should know that exploring the sort of energy constantly at us should be in the middle of the envelope of the anti-cheating plug on the standard bottle below neck ring is in screw thread, according to the present invention, design a kind of like this plug envelope of having improved already, it has comprised the feature of all needs:

1. it has a kind of exterior contour of smooth linear.

2. it is to adopt " conventional " opposite opened and screw-type press forming, is about to center pin " collision " rapidly, thereby does not need special mould pressing technology.

3. it can adopt conventional cap sealing machine to be screwed to or to be added on the bottle vertically, and does not need less important work or Special Equipment.

4. it can join on the standard bottle and special structure need not arranged to neck ring.

5. when adding this plug envelope, frangible nib is broken, but when removing the plug envelope in the ban, this nib just will break.

For this purpose, we produce a kind of safety strap for the first time, the top of table combines all characteristics of frangible nib and Drive ratchet/tooth/pallet in having of it is smooth, and then having in its bottom can be by the identical right a pair of locking crank lug that part forms of splitting.This kind locking crank lug preferably is made of two or three pairs of tenons, and the latter is near the base of frangible ring skirt inwardly and bending up, and can be promptly to the next door bending when on screw thread by Bottle ﹠ Can and/or the neck ring.But when entering in the normal pits under this ring as soon as neck ring is crossed in the grazing already of this tenon, tenon just will play a part spring and will turn back to its initial horizontal top margin, make it to lock under the level " top cover " that forms by neck ring above it, in any case and " pulling " can not make all tenons break away from neck rings yet, and neck ring just must be broken when backing out the plug envelope.The accurate profile of tenon is unimportant, and they can partly be formed by the sidewall opening of mould, and the shape of this opening is also unimportant.Need only point out that this opening can for example form once, two or three pairs of relative groups enough by " conventional split parts ".These tenons preferably are radioactive spread pattern from planar view, so that be applied on the standard bottle, although these tenons preferably form by being in 180 ° of flat parts of splitting relatively that join the inner core pin place to.

The following horizontal edge of each opening preferably is elongated shape, gets so that each tenon can immediately be placed around its pivot(ing) point.Not so can see, when a tenon at rotary course when the neck ring, the lower edge of this tenon when the tenon rotation with jam on neck ring.

In order more to be expressly understood the present invention, now describe with way of example contrast accompanying drawing, in the accompanying drawings:

Fig. 1 is a section-drawing, and it intercepts with the formed assembly set of the present invention of standard bottle by plug envelope of the present invention.

Fig. 2 is the part side-looking of above-mentioned plug envelope, the figure in part elevation profile.

Fig. 3 is the fragmentary cross-sectional view that this plug is enclosed in the A-A planar section.

From accompanying drawing as seen, this plug Feng Youyi have a top 2 with a cap portion 1 of hanging skirt 3, this hangs skirt and is connected to an anti-cheating with 5 upper limb by frangible joint tongue 4.The lower edge of hanging skirt 3 is provided with tooth 6, can with 7 engagements of the tooth on 5 upper limbs, twist when closing in that the plug envelope is initial like this, just promote to be with 5 around cap portion 1.Negative thread 8 is arranged in the cap portion 1, can mesh with the outside thread on the relevant bottle neck.

Be with 5 in its underpart 14, to be provided with opening 10, for example can be referring to Fig. 2.

Be with on 5, be formed with on the lower edge 13 of each opening 10 inwardly and acclivitous tenon 12, profile shown in all desirable figure of each tenon 12 is in order to avoid sharp-pointed turning occurs, and the latter is when the stubborn correct location that has when closing for fear of tenon of plug envelope.

In the operation, this plug envelope is twisted down be incorporated into one on the bottle of can earlier, neck ring 11 engagements on the tenon 12 on 5 and the bottle.Further tighten again, impel elasticity tenon 12 at it when the neck ring 11, enter the position of a perpendicular from their obliquity.At last, in case the top of each tenon 12 moves past the bottom of neck ring 11, each tenon promptly returns and embeds its normal obliquity as shown in Figure 1, and this just makes each tenon 12 charge into into corresponding opening 10, and allows the below of top next-door neighbour's neck ring 11 of each tenon 12.The plug envelope of this moment promptly is in its anti-cheating position, and this is because under the tenon and/or other component condition that do not damage the plug envelope, the plug envelope can not be taken off from bottle.For example, be intended to back out plug envelope, just will make in the cap portion 1 and carry from bottle, 5 can not 1 liter must be very high but be with cap portion, because the top of each tenon will be to the downside that touch neck ring 11, and will cause frangible joint tongue 4 to break like this.

Should be understood that the aforementioned cap portion of screwing on and backing out is narrated as an example.According to the present invention, the cap portion that pushes to and push also can be set, when this situation unloaded the plug envelope, because frangible nib breaks and just will separate from cap portion 1, this just can find to have carried out already cheating immediately or open mouth with 5.
