Abstract

The utility model relates to a double-layer cover of a controllable switch, wherein an upper layer cover comprises a circular upper layer cover top surface (1) with four semicircular gaps, four arc-shaped rotating pieces (2) which are vertically connected with the edge of the upper cover and are provided with vertical bulges, a bulge (3) arranged at the inner side of the rotating sheet (2), two arc single sheets (4) vertically connected with the rotating sheet (1), the lower cover comprises a hollow concentric circular lower cover top surface (5), an annular single sheet (10) which is vertically connected with the edge of the top surface (5) of the lower cover and surrounds the periphery of the upper cover, a cylindrical storage box 8 which is vertically connected with the hollow position of the top surface (5) of the lower layer cover and is sealed at the bottom surface and is opened at the top surface, air holes (9) which are symmetrically opened at the front and the back, a groove (7) which is arranged on the outer side of the annular single sheet (10) and is matched with the bulge (3) on the inner side of the rotating sheet (2), a rotary screw thread (6) which is matched with the screw thread of the opening of the packaging can at the inner side of the annular single sheet (10).

Description

Double-layer cover of controllable switch

The technical field is as follows:

the utility model relates to a with the food jar body complex lid, in particular to double-deck lid that can embed medicament of internal thread outer notch rotation type belongs to bottle lid technical field.

Background art:

the existing food can is internally provided with small-package deoxidizer, desiccant and the like to keep a low-oxygen dry environment in the container, but the can cover is opened for a long time to expose the can in flowing air, and the deoxidizer in the small package is invalid. Repeated opening reduces the effect of the deoxidizer. Some canned goods with larger volume and heavier mass have larger demand on the amount of the deoxidizer, and the deoxidizer in a small bag cannot meet the demand. In addition, some foods should not be added with deoxidant, desiccant, etc.

The existing food packaging tin can not solve the problems.

The invention content is as follows:

the cover of the utility model is made in view of the background conditions, and the novel cover solves the problem that the medicaments such as deoxidizer, drying agent and the like which are arranged in the packaging can act when and keep the long-term efficacy. The storage space is increased on the lower cover part by using a double-layer cover structure, and the working environment of the medicament is realized by controlling the opening and closing of the cover and the tank body.

A controllable switch's double-deck lid, wherein the upper strata lid is including four semicircular notch's circular upper cover top surface 1, have vertical bellied four convex revolving fragment 2 with the perpendicular connection in upper cover edge, at 2 inboard archs 3 of revolving fragment, two arc monolithic 4 of being connected with circular upper cover top surface 1 is perpendicular, lower floor's lid includes hollow concentric circular shape lower floor's lid top surface 5, with 5 edge vertical connections in lower floor's lid top surface surround its a week annular monolithic 10, the bottom surface of being connected perpendicularly with the 5 cavity positions in lower floor's lid top surface seals top surface open-ended cylinder and puts thing box 8, symmetrical bleeder vent 9 of opening around, 3 matched with recess 7 in the inboard arch of annular monolithic 10 outside and revolving fragment 2, at annular monolithic 10 inboard and the identical rotatory screw thread 6 of packing jar mouth screw thread.

The specific implementation mode is as follows:

the utility model relates to a with food package jar mouth complex lid, in particular to double-deck lid that can embed medicament of internal thread outer notch rotation type. The present invention will be further described with reference to the following examples, but the present invention is not limited to the following examples.

Example 1

Combining the upper layer cover with the lower layer cover, wherein the top surface 1 of the upper layer cover is coincided with the top surface 5 of the lower layer cover; the bulges 3 at the inner sides of the four circular arc-shaped rotating pieces 2 of the upper layer cover are combined with the grooves 7 at the outer sides of the annular single pieces 10 on the lower layer cover; the two arc single sheets 4 of the upper layer cover are combined with the cylindrical storage box 8 of the lower layer cover; the rotary screw thread 6 at the inner side of the ring single sheet 10 of the lower cover is matched with the screw thread of the opening of the packaging can.

When using double-deck lid to carry out jar mouth and sealing, rotatory whole combined cover because upper cover is the biggest with hand area of contact, can make upper cover rotatory under the effect of frictional force at first, the arch 3 of upper cover at this moment is at the recess 7 internal rotation of lower floor's lid, and the length of recess 7 is greater than arch 3, and arch 3 will stop rotatoryly when changeing to the end and block, and lower floor's lid continues to rotate under the effect of frictional force, and it is sealed up to rotatory screw thread 6 and jar mouth screw thread completion. Under the closed state, the two arc single sheets 4 just expose nine air holes 9 which are symmetrical front and back in the storage box 8, so that the medicament arranged in the storage box 8 can play a role in the sealed state.

When opening double-deck lid, the upper cover can rotate earlier under the effect of frictional force, and the upper cover is rotatory to be stopped when protruding 3 rotates 8 dead ends of recess and blocks, and lower floor's lid atress continues to rotate until rotatory screw thread 6 and jar mouthful screw thread separation, and the jar is opened. At the moment, the two arc single sheets 4 are in a state of sealing the air holes 9 which are symmetrical front and back in the storage box 8, so that the medicament arranged in the storage box 8 is isolated from the air, and the use effect of the medicament in the pot is prevented from being reduced due to the influence of the external environment.
