Abstract

The utility model discloses a locking type bottle cap. The utility model is composed of an inner cap and an outer cap which are sheathed with each other, wherein, the combined periphery face of the inner cap and the outer cap is provided with annular groove fastening structures which are fastened with each other, and the bottle caps are caused to be difficult to separate after the bottle caps are sheathed with each other; the combined end face is provided with a plurality of teeth and grooves which are uniformly distributed and are engaged with each other in a radial direction and ratchet pawls and ratchet teeth which are engaged in a single direction. The outer cap is caused to slide by the ratchet pawls and the ratchet teeth when the outer cap is rotated so that the bottle cap as being locked can not be opened, the outer cap is rotated only when the outer cap is pressed downwards by force, the teeth and the grooves of the inner cap and the outer cap are engaged, and the inner cap is driven by the outer cap, and the bottle cap is opened.

Description

Last lock bottle cap

The utility model relates to and is widely used in medicine bottle, the bottle cap of food-bottle.

No matter be cap of medicine bottle or food-bottle bottle cap on the market, it generally all is single lid formula, be easy to open, even bottle cap adds the combined type of chock plug, also be easy to open, as long as just it can be opened along the certain orientation rotation, such bottle cap lacks safety, medicine or the food that should not eat in the bottle have been eaten just in case opened mistake easily by children, will cause certain injury or waste, threat to life even, therefore, take place for fear of above-mentioned incident, except big people take the perch placement, do not have other way.

The purpose of this utility model just provides a kind of last lock bottle cap that can prevent effectively that children from opening easily.

According to above-mentioned purpose, embodiment of the present utility model is: go up the lock bottle cap and comprise the lid that screws with the bottleneck spiral, it is characterized in that described lid is made up of the inner cap and the enclosing cover of mutual fit, on the periphery of inside and outside lid combination, be provided with the annular catching groove structure of mutual fastening, on end face, be provided with ratchet, the ratchet of intermeshing tooth, groove and the one way engagement of a plurality of radial equipartitions.

The utility model is by interior, the compound type bottle cap that enclosing cover is formed, because on the periphery of both combinations and the architectural feature on the end face, in making, be difficult to behind the enclosing cover fit separate, when rotary outer cover, the ratchet of one way engagement, ratchet makes forward the rotation can't turn, both unpowered transitive relations and retrograde rotation can only be skidded mutually, therefore, bottle cap cans be compared to locks, can't open, only depressing in enclosing cover makes, the tooth of enclosing cover, during the groove engagement, could be driven inner cap and be opened bottle cap by enclosing cover, such opening ways normal children be also unknown, even know that also not having enough hand-powers opens bottle cap, so can prevent effectively that children from opening bottle cap easily, cause unnecessary injury can play effective function to preventing children.

Fig. 1 is the utility model structural representation.

Fig. 2 is the outer top surface structure scheme drawing of inner cap.

Fig. 3 is the A-A section-drawing of Fig. 2.

Fig. 4 is an enclosing cover inner top surface structural representation.

Fig. 5 is the B-B section-drawing of Fig. 4.

Below with reference to above-mentioned accompanying drawing the utility model embodiment is described in detail again.

Last lock bottle cap (referring to Fig. 1-5) is made up of the inner cap (1) and the enclosing cover (2) of mutual fit, and inner cap and bottleneck spiral screw.

The periphery of inside and outside lid combination is provided with annular catching groove (6) structure of mutual fastening, and when the ring buckle of inner cap buckled in the circular groove of enclosing cover, inside and outside lid promptly can not separate.

The end face of inside and outside lid combination is provided with ratchet (3), the ratchet (7) of intermeshing tooth (4), groove (5) and the one way engagement of a plurality of radial equipartitions.

The tooth of inside and outside lid, slot cross-section can be trapezium structure or rectangular configuration, look the bottle cap size and get 3-16 and be advisable, and present embodiment tooth, slot cross-section are selected rectangular configuration for use, and external diameter is that the bottle cap of 40 millimeters of Φ selects for use 10 in tooth, groove for good.

The ratchet of one way engagement, ratchet generally are advisable with 3-8, and selecting 5 for use for good, and ratchet is flap, is about 30 ° with end face angle α for the bottle cap of 40 millimeters of Φ.

Behind the inside and outside lid fit, ratchet and ratchet one way engagement, so forward rotation changes motionless, and retrograde rotation does not have drive connection, can only hear clatter! A clatter! Sound, bottle cap cans be compared to lock still can't be opened, if will open bottle cap, must firmly depress enclosing cover, on this moment, ratchet was crushed out of shape the tooth that makes inside and outside lid, groove engagement, rotary outer cover when depressing, enclosing cover promptly drove the inner cap rotation, thereby bottle cap is screwed off.
