Abstract

The utility model discloses a safety bottle cap, which comprises a first connecting body arranged at a bottle opening and a second connecting body arranged at a cap body which are connected by screw threads, realizing the seal of the bottle opening; the first connecting body and the bottle opening are combined into a body; the shape of the second connecting body is basically the same as the shape of the cap body, and the second connecting body is nested in the cap body at intervals; the second connecting body can do axial movement relative to the cap body in a specified amount; an end surface positioning mechanism is arranged between the second connecting body and the cap body; when the cap body bears the downward axial force, the end surface positioning mechanism can make the cap body and the second connecting body rotate together; when the axial force is cancelled, the cap body and the second connecting body can rotate freely and relatively. The utility model solves the problem of mistaken drinking and eating of children because spiral cap bodies are easy to open. The utility model has the advantages of simple structure, convenience, high safety and application for seal of bottle openings of pharmaceutical product food packing bottles and children food packing bottles.

Description

A kind of resistant closure

Technical field

The utility model relates to the bottle cap technical field.

Background technology

Medicine bottle uses lid helix closed mostly.Concerning children, so also dangerous, because he can open it easily, cause the mistake drink to eat by mistake.

The utility model content

The purpose of this utility model is: a kind of comparatively safe resistant closure is provided, solves the spiral lid and be easy to be opened, the problem that causes children's mistake drink to eat by mistake.

For achieving the above object, the technical solution of the utility model is: a kind of resistant closure, comprise first connector of bottle mouth position and second connector at lid place, first connector and second connector are threaded togather, realize the sealing of bottleneck, first connector and bottleneck are integrated, second connector has with essentially identical shape of lid and gap and is nested in the lid, second connector can move axially by specified amount with respect to lid, be provided with the end face detent mechanism between second connector and the lid, when lid is subjected to downward axial force, this detent mechanism can make lid rotate with second connector, during the axial force cancellation, the lid and second connector can rotate relatively freely.

Owing to adopted technique scheme, want to open lid, just must firmly push lid, lid is rotated with second connector, lid could be screwed off.Children do not know this reason, so he can not open lid easily, have not played and can drink the safe effect of eating by mistake by mistake.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structure cutaway view of the utility model embodiment;

Fig. 2 be embodiment illustrated in fig. 1 in the structural representation of second connector,

Fig. 3 is the structural representation of first kind of embodiment of middle lid embodiment illustrated in fig. 1;

Fig. 4 is the structural representation of second kind of embodiment of middle lid embodiment illustrated in fig. 1.

The specific embodiment

As shown in Figure 1, a kind of resistant closure, comprise first connector 4 at bottleneck 3 places and second connector 2 at lid 1 place, first connector 4 and second connector 2 are threaded togather, realize the sealing of bottleneck 3, first connector 4 is integrated with bottleneck 3, second connector 2 has with lid 1 essentially identical shape and gap and is nested in the lid 1, second connector 2 can move axially by specified amount in lid 1, be provided with the end face detent mechanism between second connector 2 and the lid 1, when lid 1 is subjected to downward axial force, this detent mechanism can make lid 1 rotate with second connector 2, during the axial force cancellation, the lid 1 and second connector 2 can rotate relatively freely.

Shown in Fig. 2,3, described end face detent mechanism is to constitute like this: the outer face of second connector 2 is provided with some axial projections 21 of along the circumferential direction arranging, the inner end surface of lid 1 is provided with quantity and arrangement and projection 21 corresponding axial depressions 11, and the shape of described depression 11 and projection 21 are suitable.

Shown in Fig. 2,4, described end face detent mechanism also can constitute like this: the outer face of second connector 2 is provided with some axial projections 21 of along the circumferential direction arranging, the inner end surface of lid 1 is provided with quantity and arrangement and axial projections accordingly with the projection 12 of groove, and the groove of the shape of described projection 21 and projection 12 is suitable.

Want to open lid 1, just must firmly push lid 1, make axial projections 21 snap in the groove of projection 12 or cave in 21, at this moment lid 1 can rotate with second connector 2, lid 1 could be screwed off.Children do not know this reason, so he can not open lid easily, have not played and can drink the safe effect of eating by mistake by mistake.

Claims
