Abstract

The utility model discloses a container cap with alarm function. The container cap comprises an outer cover and an inner cover arranged in the outer cover, wherein the inner cover can be mutually rotated with the outer cover, internal threads can be arranged in the inner wall of the cover edge of the inner cover, ratchets are arranged along the peripheral direction of the inner top surface of the outer cover, pallets are arranged on the upper surface of the inner cover along the peripheral direction, and the ratchets are matched with the pallets. The cap can prompt people through generating sound, can accurately adjudge whether the cover is tightly screwed down or not, avoids the phenomenon that the cap can not be reliably sealed since the cover is screwed too loose, or the cap is screwed too tight and the opening is arduous, and the damage to the cap can be avoided.

Description

Container cover with the tight function of newspaper

Technical field

The utility model relates to a kind of container cover, specifically, is a kind of container cover with the tight function of newspaper.

Background technology

For sealed container port, the screw thread that matches is set on lid and vessel port usually, this helicitic texture has good seal performance, opens and closes advantage easily.Yet, present container cover all be with the people feel judge whether to tighten.Needing the occasion of strict seal, as fuel tank, people often rotate to lid and can not rotate as the sign of tightening again.Because of can't judging accurately that whether lid is tightened, and exists following point in actual use: (1) lid or stubborn De Taisong, can't positiver sealing, or twist too tightly, require great effort again when opening; (2) if firmly excessive, fragile lid.In a word, there is awkward problem in present lid.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of container cover with the tight function of newspaper, judges with accurate whether lid is tightened.

In order to address the above problem, the container cover with the tight function of newspaper of the present utility model comprises the inner cap in enclosing cover and this enclosing cover, and inner cap and enclosing cover can rotate mutually, and is provided with negative thread at the inwall on inner cap lid edge, is circumferentially with ratchet on the inner top surface edge of described enclosing cover; Upper surface edge at described inner cap is circumferentially with ratchet, and this ratchet cooperates with described ratchet.

After adopting technique scheme, under the effect of ratchet and ratchet, inner cap and enclosing cover can not rotate mutually, like this, drive the inner cap rotation by rotary outer cover, and inner cap and vessel port are tightened; When inner cap and vessel port were tightened, when continuing rotary outer cover, ratchet and ratchet slided mutually, produced sound, reached the purpose of reminding the people like this, had avoided because of lid or stubborn De Taisong, can't positiver sealing and twist too tightly, and the problem of requiring great effort again when opening; Can prevent to damage lid in addition.

Preferred embodiment as technique scheme, edge, top at described inner cap is circumferentially with circular groove, and this circular groove is divided into the disk on top and the interior lid of bottom with inner cap, is circumferentially with through hole in the disk upper edge, the bar portion of described ratchet is positioned at this through hole, and the claw of ratchet exceeds through hole.When ratchet and ratchet slided mutually, circular groove can play the purpose of stepping down for the claw of ratchet.

As another preferred embodiment of technique scheme, the inner top of lid is provided with metallic gasket in described, with the positiver sealing vessel port.

As another preferred embodiment of technique scheme, be circumferentially with projection on the upper inside wall edge on described enclosing cover lid edge, this projection is the inclined-plane over against the side of described inner cap, is adding man-hour like this, enters in the enclosing cover easily in the inner cap; The upper surface of projection and the inner top surface of enclosing cover form the groove spacing to described disk, and the outward flange of disk is positioned at groove, reach the purpose that inner cap and enclosing cover rotate mutually like this.

As another preferred embodiment of technique scheme, the outer wall of lid is along being circumferentially with raised line in described, and this raised line is parallel with the line of centers of interior lid.

Compared with prior art, the beneficial effects of the utility model are: the utility model is reminded the people by producing sound, can judge accurately whether lid is tightened, and has avoided twisting De Taisong because of lid, can't positiver sealing, or twist too tightly, the problem of requiring great effort again when opening; Can prevent to damage lid in addition.
