Abstract

The utility model relates to a plastic bottle cover with an anti-theft structure. The lower edge at the side end of the plastic bottle cover convexly extends, forming one to a plurality of connecting sheets. Both side ends of each of the connecting sheets are respectively connected with both ends of a pull band by a strong connecting point and a weak connecting point. The pull band surrounds the lower edge of the plastic bottle cover and is connected with the bottom edge of the plastic bottle cover through micro-connecting points. Blocking stopping points are arranged on the inner edge surface of the pull band at intervals, which creates a blocking feeling when the cover is screwed. When the cover is opened, the micro-connecting points and the weak connecting points break and the pull band can be fully disengaged from the bottle cover and can not be left on the bottle mouth. Moreover, the utility model can not be recovered to impersonate an original product and inventing goals that the utility model is anti-theft and empty bottles are easy to recover are achieved.

Description

Improve the anti-pirate of the open plastic bottle closure of structure

The utility model relates to a kind of plastic bottle closure, relates to a kind of plastic bottle closure with antitheft opening structure or rather.

The main effect of bottle cap is that the sealing bottleneck prevents that bottle interior liquid from flowing out, and when the bottle cap of design beverage bottle used in everyday, medicine bottle etc., also mainly considers its leak resistance.The bottle cap that tradition is used adopts the aluminum plate material mostly; its major defect is behind the bottle cap of outwarding winding, the scratch user of hard toothed edge regular meeting that the aluminium lid bottom is remaining, but after replacing plastic bottle closure; though soft burr can the scratch user, but new problem occurred.

In conjunction with referring to Fig. 1, Fig. 2, the builder is in order to prevent bottle cap 1 and endless belt 11 delamination, and closely is provided with more contact 12, and the body 3 of also combining closely of shelves stop 12 (see figure 2)s on endless belt 11 inner edge surfaces.Must reverse bottle cap energetically when opening bottle cap 1 bottle cap 1 is separated with endless belt 11, therefore cause bottle interior liquid to spill easily.The recess 31 of container finish is to supply ccontaining endless belt 11, when bottle cap 1 is outwarded winding with after endless belt 11 separates, endless belt 11 often resides in this recess 31 and can't deviate from, behind the bottle cap 1 of screwing on again, to be difficult to offer an explanation this container bottle and whether be unlocked, and make, sell fake and forged product to the lawless person and created condition.In addition, consider that environmental protection often will reclaim empty bottle and make other article, but because bottle mostly is PVC, PET product, bottle cap mostly is PE, PP product, must spend more one formality during recovery and take off the endless belt that is deposited on the bottleneck, has increased cost recovery.

The purpose of this utility model is a kind of anti-pirate of the open plastic bottle closure that improves structure of design, and bottle cap just can not restore once opening, and bright eye can be debated, and endless belt also peels off from bottle mouth position fully with bottle cap, not only has the effect of anti-pirate of the open also to be beneficial to recovery.

The utility model improves the anti-pirate of the open plastic bottle closure of structure, it is characterized in that:

Described plastic bottle closure side lower edge has protruded out connecting strap, and the connecting strap two side ends links drawstring two ends by strong point of connection and weak point of connection respectively, and drawstring links the plastic bottle closure root edge around the plastic bottle closure lower edge and by little point of connection.

Described connecting strap uniformly-spaced is arranged on plastic bottle closure side lower edge, and described drawstring is attached between any two connecting straps by strong point of connection and weak point of connection respectively, and described drawstring apical margin links the plastic bottle closure root edge by more than one little point of connection.

Block point, block card plastics body are set on the described drawstring inner edge surface at interval.

The effect of weak, the little point of connection between block point between drawstring and bottle cap and drawstring and connecting strap, bottle cap, make the bigger retardance sense of generation when outwarding winding bottle cap, but drawstring is once tearing, each little, weak point of connection fracture, drawstring is radial disengagement, promptly can peel off from body fully, can't restore, reach anti-pirate of the open and can be on bottleneck the improvement purpose of residual drawstring.

Further specify technology of the present utility model below in conjunction with the embodiment accompanying drawing

Addressed before Fig. 1, Fig. 2 and repeated no more.

Referring to Fig. 3 to Fig. 6, the plastic bottle closure of anti-pirate of the open is generally PE, PP product, seals use for PVC, PET plastic bottle.Fig. 3 to Fig. 6 illustrates the improvement structure of first kind of bottle cap.

The side root edge of bottle cap 2 protrudes out a connecting piece 21, connecting strap 21 1 sides have the last one point of connection 22 to link a drawstring 23, the top edge of drawstring 23 at interval suitably distance little point of connection 24 is set and links with the root edge of bottle cap 2, link with a weak point of connection 25 another side again around the drawstring behind the bottle cap root edge 23, then encircle on the inner edge surface of drawstring 23 and establish some block points (seeing Fig. 4, Fig. 6) with connecting strap

Owing to be equipped with block point 26 on the inner face of drawstring 23, when outwarding winding, bottle cap 2 produces the retardance sense, drawstring 23 is separated with bottle cap 2, drawstring 23 is that perk can't be restored behind the whiz bottle cap, if container bottle is by pirate of the open or normally opened and can learn, therefore the thing that can wrongly not purchase false product takes place, and reaches anti-theft effect really.

When reclaiming PVC, PET bottle,, need not to divest the residual drawstring 23 that reclaims on the body 3, thereby can reduce recycling step, cost-cutting because drawstring 23 has been removed in the lump with bottle cap.

Referring to Fig. 7, Fig. 8, be the improvement structure of second kind of bottle cap.Root edge end in bottle cap 2 uniformly-spaced is provided with several connecting straps 21, connecting strap 21 two side ends equally respectively establish the last one point of connection 22 and weak point of connection 25 links with

drawstring

23,21 of two connecting straps connect with a drawstring 23, the top of drawstring links with little point of connection 24 and bottle cap equally, little point of connection 24 and weak point of connection 25 fractures made whole drawstring 23 be radial disengagement after bottle cap was outwarded winding, and the drawstring 23 after the disengagement also can't restore, drawstring can not remain on the body yet, reaches the purpose of anti-pirate of the open equally.

The utility model is by being provided with connecting strap and drawstring is set between connecting strap at the bottle cap root edge, link by strong, weak, little point of connection between drawstring and bottle cap, connecting strap, the drawstring inner face is provided with the block point, playing has retardance sense and drawstring can break away from the effect of bottle cap fully when outwarding winding bottle cap, reach the purpose of preventing pirate of the open.
