Description

A kind of resistant closure

Technical field

The utility model relates to a kind of resistant closure.

Background technology

Common Bottle cap structure is: comprise lid, described lid madial wall is provided with screw thread; During use, rotary bottle cover can screw bottle cap and bottle to screw togather in the direction of the clock, by anticlockwise direction rotary bottle cover, can bottle cap and bottle be unscrewed separated; The bottle cap of having opened and bottle screw-joining structure, be very easily opened, once children are subject to ordering about of curiosity, this bottle cap and bottle unscrewed separated, and the material that is unsuitable for children in bottle is taken in by children, will endanger children's health.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of resistant closure, prevents that children from unscrewing bottle cap and bottle separated, has guaranteed that material in Packaging Bottle is not opened voluntarily by children and the accident eaten by mistake occurs.

For solving the problems of the technologies described above, the utility model adopts following technical proposals: a kind of resistant closure, comprise that enclosing cover and madial wall establish threaded inner cap, described enclosing cover is socketed in inner cap outside matchingly, on the inner peripheral surface of described enclosing cover inner roof wall and on the outer circumference surface of the outer roof of inner cap, be respectively equipped with the projection that can mesh, enclosing cover lid mouth is provided with position limiting convex ring, with restriction inner cap, by position limiting convex ring, deviate from, inner cap Gai Kou lower end touches in position limiting convex ring inwall place, the protruding upper surface of the outer roof of inner cap apart from the vertical line height of enclosing cover Gai Kou lower surface lower than the protruding lower surface of enclosing cover inner roof wall the vertical line height apart from enclosing cover Gai Kou lower surface, enclosing cover inner roof wall, between the outer roof of enclosing cover madial wall and inner cap, form accommodating cavity, in accommodating cavity, be provided with a non-metal elastomer block or spring, this structure design is in order to keep between the projection of the outer roof of the projection of enclosing cover inner roof wall and inner cap in the situation that not being subject to downforce, owing to there being the support of non-metal elastomer block or spring between to keep relative separation, avoid do not apply a certain amount of while pressing down external force, intermeshing between the two, to prevent that children from only applying rotational force and just resistant closure can be outwarded winding, the utility model only has elder generation to apply a certain amount of downforce to resistant closure, makes the projection of enclosing cover inner roof wall and the projection of the outer roof of inner cap intermeshing, applies a certain amount of rotational force simultaneously again, just resistant closure can be opened.

Described non-metal elastomer block or both ends of the spring are individually fixed on enclosing cover inner roof wall and the outer roof of inner cap.

Described non-metal elastomer block or spring one end are fixed on the outer roof of enclosing cover inner roof wall or inner cap, and this non-metal elastomer block or the spring other end and inner cap roof or enclosing cover inner roof wall touch mutually outward.

The material of described non-metal elastomer block is elastic caoutchouc or elastic silica gel.

Described outer cap surface is provided with anti-skidding raised line, prevents from when palm from contacting with enclosing cover skidding, and strengthens the friction force of the outer roof of palm or finger and enclosing cover or lateral wall, is convenient to resistant closure and bottle to unscrew separated.

Described anti-skidding raised line is included in the anti-skidding raised line of annular that the outer roof of enclosing cover middle part arranges, and centered by the anti-skidding raised line of this annular to the anti-skidding raised line that is radial arrangement structure of enclosing cover excircle direction setting, this structure design can increase the area of contact of palm and outer hd top face, simultaneously, the friction force covering outside while increasing palm rotary outer cover, prevents that palm from covering and skidding outside.

The anti-skidding raised line that is radial arrangement structure of the outer roof of described enclosing cover extends enclosing cover lateral wall place downwards by enclosing cover excircle place, to increase the friction force of finger and enclosing cover lateral wall, spiral cover is become and easily operate.

It is separated that the utility model prevents that children from unscrewing bottle cap and bottle, guaranteed that material in Packaging Bottle is not opened voluntarily by children and the accident eaten by mistake occurs.

The specific embodiment

Shown in Fig. 1～Fig. 7, a kind of resistant closure, comprise that enclosing cover 1 and madial wall are provided with the inner cap 2 of screw thread 21, described enclosing cover 1 is socketed in inner cap 2 outsides matchingly, the inner peripheral surface of described enclosing cover 1 inner roof wall is provided with the projection 11 that can mesh, the corresponding projection 22 that can mesh that is provided with on the outer circumference surface of described inner cap 2 outer roofs, enclosing cover 1 lid mouth is provided with position limiting convex ring 12, inner cap 2 Gai Kou lower ends touch in position limiting convex ring 12 inwall places, projection 22 upper surfaces of inner cap 2 outer roofs apart from the vertical line height of enclosing cover 1 Gai Kou lower surface lower than projection 11 lower surfaces of enclosing cover 1 inner roof wall the vertical line height apart from enclosing cover 1 Gai Kou lower surface, enclosing cover 1 inner roof wall, between enclosing cover 1 madial wall and the outer roof of inner cap 2, form accommodating cavity, in accommodating cavity, be provided with a non-metal elastomer block 3.

Described non-metal elastomer block 3 one end are fixed on the outer roof of inner cap 2, and these non-metal elastomer block 3 other ends touch mutually with enclosing cover 1 inner roof wall.
