Description

Bottle cap

Technical field

The utility model relates to a kind of bottle cap technology, specifically is a kind of bottle cap of Childproof.

Background technology

Current common bottle cap all is one of the forming, screw thread on the madial wall of bottle cap, and bottle cap can cover bottle cap on bottleneck at clickwise on the bottleneck, bottle cap can be opened during left-hand revolution; When some should not take article when placement in this bottle, guard against the family child and take unlatching, and wrongly take the interior article of bottle, bring endless worry to life.

The utility model content

The purpose of this utility model is to provide a kind of bottle cap of new structure, and bottle cap can cover bottle mouth position with bottle cap when just changeing, and the bottle cap bottle cap that can skid is easily opened during contrary revolving, and can prevent effectively that child from wrongly taking the generation of incidents such as bottle interior medicine.

For achieving the above object by the following technical solutions:

A kind of bottle cap is characterized in that: be made up of lid cover and cover core, the bottom of the madial wall of described lid cover is provided with annular convex rib, and the inner top that overlaps at lid also is provided with several convex tendons, and convex tendon is arranged in the form of a ring; Described cover core is placed in the lid cover and can moves up and down, its outside dimension is a bit larger tham the size of covering the annular convex rib internal diameter that puts, be provided with several boss at the top of cover core, boss is arranged in the form of a ring, naturally form between each boss and cover the recess that the convex tendon that puts matches, on the upper surface of boss, also be provided with the slope.

The utility model is divided into lid cover and cover core with bottle cap, is provided with convex tendon and the boss that cooperatively interacts between lid cover and cover core, and the place also is provided with the slope at the boss upper surface; When bottle cap covers, the convex tendon of lid cover inner top just in time is placed in the recess between each boss of cover core top, drive the cover core rotation by convex tendon during the rotation of lid cover, the bottle cap lid is tight, and when opening bottle cap, usual condition lower cover cover by on carry, when making the rotation of lid cover, the convex tendon that lid puts can not block the cover core convex platform, but skids along the slope of cover core convex platform upper surface, bottle cap can not be opened, has only afterburning lower cover cover, make that the lid cover could drive cover core and rotate, and bottle cap is opened when convex tendon on the lid cover inner top can block the slope side sidewall of cover core top boss; Adopt above structure can prevent effectively that children from opening bottle easily and wrongly taking a bottle interior medicine, increase the safety of bottle greatly.

Description of drawings

Fig. 1, the utility model inner structure scheme drawing;

The structural representation of Fig. 2, the utility model cover core;

The structural representation of Fig. 3, the utility model lid cover.

The specific embodiment

As Figure 1-3, a kind of bottle cap comprises lid cover 1 and cover core 2, is provided with annular convex rib 11 in the bottom of the madial wall that covers cover 1, also is provided with several convex tendons 12 at the inner top that covers cover 1, and described convex tendon 12 is arranged in the form of a ring; Described cover core 2 is placed in lid cover 1 inside and can moves up and down, cover core 2 medial surfaces are provided with screw thread, cover core 2 outside dimensions are a bit larger tham the size of annular convex rib 11 internal diameters on the lid cover 1, be provided with several boss 21 at cover core 2 tops, boss 21 also is to arrange in the form of a ring, can nature formation overlap the recess 23 that the convex tendon 12 on 1 matches between each boss 21, on the upper surface of boss 21, also be provided with slope 22 with lid.

The utility model is provided with convex tendon 12 and the boss 21 that cooperatively interacts between lid cover 1 and

cover core

2,21 upper surface places also are provided with slope 22 at boss; When bottle cap covers, swivelling cover cover 1, the convex tendon 12 of lid cover 1 inner top can just be placed in the recess 23 between each boss 21 of cover core 2 tops, thus lid cover 1 energy of rotation drives cover core 2 rotations by convex tendon 12, and the bottle cap lid is tight; And when opening bottle cap, can do not added the strength that presses down on the usual condition lower cover cover 1, when making 1 rotation of lid cover, convex tendon 12 on the lid cover 1 can not block cover core 2 convex platforms 21, but can skid along the slope 22 of cover core 2 convex platforms 21 upper surfaces, and bottle cap can not be opened, only on lid cover 1, add that presses down a strength, make when convex tendon 12 on lid cover 1 inner top can block the slope 22 side sidewalls of cover core 2 top boss 21 that lid cover 1 could drive cover core 2 and rotated this moment, and bottle cap is opened; Adopt above structure to increase the safety of bottle greatly, prevented that effectively children from wrongly taking bottle generation of interior article incident, reduced some unnecessary troubles.

Claims
