Description

False proof liquid holding bottle of roof pressing type and bottle cap thereof

The utility model belongs to bottle and the bottle cap goods are made the field.

Anti-counterfeiting mark forms the disposable antiforging bottle of fracture because its its specific structure should not directly be used spiral cover after encapsulation during uncork.General now employing one ratchet ring solves this problem with the mode that the outer ratchet on edge at the bottom of the spiral cover matches, a bayonet socket cutting ferrule that is about on the ratchet ring is lived the false proof pin of bottleneck, again spiral cover is screwed off the capping bottleneck, because the principle that the secondary derotation of ratchet is obstructed, also can only be when opening bottle with the downward dextrorotation of bottle cap, instantly be screwed into to a certain degree, bottle cap is disconnected with false proof pin top, and bottleneck also backs down the disconnected weak point in bottle cap top and bottleneck is gone out simultaneously.Though this structure can overcome the above problems to a certain extent, there is the processing and fabricating complexity, aligning accuracy is installed requires height, the shortcoming that productive costs is high.

The purpose of this utility model is design false proof liquid holding bottle of a kind of roof pressing type and bottle cap thereof, makes it to overcome the above shortcoming of prior art.

The purpose of this utility model is to realize by following design.

By bottleneck that is provided with false proof pin and the bottleneck packaging structure formed such as matching used bottle cap with it, has annular helical groove on the bottleneck; Bottleneck between annular helical groove and the bottleneck is provided with at least one recessed groove, and the afterbody of recessed groove terminates in the top of annular helical groove, has the transition convex edge on it.Bottle cap inside face with the false proof pin Ka Na mechanism that can block false proof pin is equipped with at least one and the corresponding elasticity convex body of the recessed groove of bottle.

After adopting design as above, the direct cutting ferrule of false proof snib of bottle cap is lived the false proof pin of bottleneck, and the elasticity convex body of bottle cap directly is connected on the bottleneck annular helical groove, need not to re-use ratchet ring etc. and can finish the bottle envelope.The product false proof ability is strong, and manufacture craft is simple, need not higher aligning accuracy, and productive costs reduces greatly.

Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.

In Fig. 2 and Fig. 3, can see the structure of containing the false proof bottle of liquid, 1 is bottle, and 2 for being provided with the bottleneck of false proof pin 3, has annular helical groove 4 on the bottleneck: the bottleneck between annular helical groove 4 and the bottleneck is provided with a recessed groove at least, recessed in this example groove is provided with two, and promptly 5,6.The afterbody of recessed groove 5 terminates in the top of annular helical groove 4, and in conjunction with Fig. 4,5 can see, has transition convex edge 7 on the following logical groove 5.

Bottle cap inside face with the false proof pin Ka Na mechanism that can block false proof pin is equipped with at least one and the corresponding elasticity convex body of the recessed groove of bottle, in this example, is provided with two elasticity convex bodys, as 8 among Fig. 3 and 9.In Fig. 1, can see, but have the false proof snib 17 that cutting ferrule is lived the false proof pin of bottleneck on the bottle cap.

During the envelope bottle, elasticity convex body 8,9 is aimed at recessed groove 5,6 respectively; False proof snib 10 is aimed at false proof pin 3, and bottle cap is pressed down, and the elasticity convex body is just inserted down and by 7 landings of transition convex edge extremely in the annular helical groove 4 along recessed groove.The particular location of elasticity convex body 8 should be in Fig. 4 a place.At this moment, because the unidirectional kayser effect between elasticity convex body and annular helical groove and the obstruction of annular helical groove, bottle cap both can not upwards be pulled out, also can not counter-clockwise turn.Can be clear that the structure situation of this moment in conjunction with Fig. 6.10 for clogging the interior plug of bottleneck among the figure, and interior have pour spout 11 beyond the Great Wall, has tegillum 12 on the pour spout.Generally speaking, a weak point 13 can be established in the bottle cap top, and weak point can be by pour spout 11 burstings of interior plug, and Fig. 8 and Fig. 9 have expressed this weak point by the appearance change before and after the bursting.

During unlatching, inhour turns bottle cap, the elasticity convex body of bottle cap (is example with elasticity convex body 8) is along the downward turn of the helical of annular helical groove, when turn to certain position, during as the b position among Fig. 6, the edge of false proof snib breaks false proof pin, as shown in Figure 7, along with the decline of bottle cap, the pour spout of bottleneck is with weak point 13 burstings of bottle cap and stretch out beyond the bottle cap, at this moment, tegillum 12 is opened liquid in the bottle can be poured out.

For avoiding unintentionally bottle cap being pressed down bottleneck is opened, can one boss be set at contiguous recessed groove afterbody place, the upper end of annular helical groove, as 14 among the figure.

In addition, the end of considering not bottle cap before opening along and bottleneck saddle 15 between the gap affects that exists attractive in appearance, can set up a shirt rim thin layer 16 in the lower edge of bottle cap as shown in figure 10, bottle cap moved down degree of being when the thickness of this thin layer and hard degree were opened not influence.

Be noted that generally speaking, occur in pairs when the following logical groove of bottleneck and the elasticity convex body of bottle cap, can select for use according to actual conditions a pair of, two pairs, or three pairs structure.

The lead angle that should also be noted that annular helical groove helical generally can be by greater than 5 degree designs, and under special situation, lead angle can be zero.
