Detailed Description

In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.

The utility model relates to a can take notes vacuum fresh-keeping lid of date of keeping is as shown in figure 1, figure 2 and figure 3, including lid body 1, sealing plug 2, date carousel 3 and silica gel circle 4, wherein the up end undercut of this lid body 1 is formed with the heavy platform district 11 with evacuating device's suction head matched with, the central point of this heavy platform district 11 puts and is provided with the suction opening 111 that runs through, sealing plug 2 installs and is used for controlling opening or closing of suction opening 111 in suction opening 111, preferably, be provided with an annular sealing muscle 112 in this heavy platform district 11, cooperate with evacuating device's suction inlet through sealing muscle 112 and form the multi-pass seal face, the sealed effect of cooperation between evacuating device and the lid body 1 like this, guarantee that the suction process takes place gas leakage; the date rotary disc 3 is of a ring structure and is arranged on the periphery of the sinking platform area 11, a month area for indicating month numbers and a date area for indicating dates are printed on the date rotary disc 3, pointers 31 are respectively arranged on the date rotary disc 3 in a sliding manner in the corresponding month area and the date area, the pointers are respectively slid to the corresponding numbers to indicate the number of months, meanwhile, the date rotary disc 3 can also be printed with a year area for indicating the number of years according to the requirement, and the pointers 31 are correspondingly arranged in the year area, so that the corresponding year can be expressed; the silica gel ring 4 is arranged on the lower end face of the cover body 1 and used for improving the sealing effect matched with the container.

In the above solution, as shown in fig. 2, a plurality of stoppers 13 are arranged at intervals on the lower end surface of the cap body 1 corresponding to the outer circumference of the suction port 111, and an air outlet channel of a pipe communicated with the suction port 111 is formed between adjacent stoppers 13; the sealing plug 2 comprises a plug body 21 capable of sliding up and down along the suction port 111, a sealing ring 22 connected with the upper end of the plug body 21 and positioned above the cap body 1, and a drop-proof ring 23 connected with the lower end of the plug body 21 and positioned below the stopper 13; when the suction port of the vacuum pumping device is aligned with the suction port 111 for vacuum pumping operation, the sealing plug 2 moves upwards along the suction port 111 to enable the anti-drop ring 23 to be pressed against the stop block 13 under the action of suction force, so that air in the preservation cover can flow out through the air outlet channel and the gap between the plug body 21 and the suction port 111 to realize vacuum pumping, and after the vacuum pumping is finished, because the air pressure in the preservation cover is smaller than the external air pressure, the external action force downwards applied to the sealing plug 2 can enable the sealing ring 22 to be sealed with the upper end face of the cover body 1, the external air is effectively prevented from entering the preservation cover, and thus, the food in the container is vacuum-stored for a long time; when the freshness protection cover needs to be opened, only the sealing plug 2 needs to be pulled to enable the plug body 21 to move upwards, so that the outside air can enter the inside of the freshness protection cover, and the freshness protection cover can be conveniently opened.

In the above-mentioned solution, preferably, the upper end surface of the cover body 1 is provided with a recessed annular groove 12 corresponding to the periphery of the platform 11, the date dial 3 is installed in the annular groove 12, the inner annular wall of the annular groove 12 is provided with a raised block 121, and correspondingly, the date dial 3 is provided with a bayonet, so that the date dial 3 is fixedly installed in the annular groove 12 by the bayonet and the block 121.

The above disclosure is only for the embodiment of the present invention, however, the present invention is not limited thereto, and any changes that can be considered by those skilled in the art should fall within the protection scope of the present invention.
