Abstract
The utility model discloses an improvement type structure of sealed lid, include: the through -hole of an intercommunication jar internal portion is offered to one jar of body and install the lid on the jar body on, through -hole department installs a sealed lid, should include by sealed lid: the column stopper of a body and perpendicular to body, its bottom surface of body set up to sucking disc form to adsorb in the surface of inner cup, its upper surface of body sets up equally to the sucking disc form, for reverse sucking disc form. The utility model discloses set up a through -hole on the lid to through a sealed lid that has the vacuum suction inlet, to bleed to internal of jar through an evacuation ware, gas is discharged through gas tank and vacuum suction inlet, after carrying out the evacuation to jar internal portion, can preserve the dress better at the internal product of jar, making it, fresh -keeping it is longer, easily rotten, and the body of sealed lid surface design from top to bottom can let the body should seal up with the lid well for the sucking disc form to can make and well seal between aspiration pump and the body, it bleeds to make can go on smoothly.
Description
Technical field:
The utility model relates to storage tank technical field, refers in particular to a kind of improved structure of seal cover cap.
Background technology:
Along with improving constantly of living standard, make the requirement of people to quality of life also more and more higher, in daily life, people often need to store some food, and a underworld gang uses storage tank.Now storage tank in the art generally all has tank body and lid, by threaded engagement between the most traditional storage tank its tank body and lid, its sealing property of the storage tank of this kind of structure is bad, owing to there is various bacterium in air, moisture and moisture, most bacterium can make food decay go bad, cause the waste of food, therefore, the sealable tank that market occurs in succession, as long as sealable tank structure now on the market is also a tank body and a lid, but threaded engagement between tank body and lid no longer, but mutually fasten, in tank body contact position is provided with a silica gel sealing ring on lid, by sealing circle, tank interior air and extraneous air are completely cut off, gas exchanges can not be produced, with the freshness date of food and extend.But the sealable tank of this kind of structure, also exists following defect: sealable tank inherence also also exists air, carries various bacterium in air, corrosion can be produced to food in tank.
Therefore, in order to most limit reach the fresh-keeping performance of sealing, the utility model proposes a kind of improved structure of seal cover cap.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of improved structure of seal cover cap.
In order to solve the problems of the technologies described above, the utility model have employed following technical proposals: a kind of improved structure of seal cover cap, comprise: a tank body and the lid be installed on tank body, lid is offered the through hole of a connection tank interior, through hole is provided with a seal cover cap, sealing lid comprises: a body and the column plug perpendicular to body, and its bottom surface of described body is set to sucker shape, to be adsorbed in the surface of inner cap; Its upper surface of body is set to sucker shape equally, is reverse sucker shape.
Furthermore, in technique scheme, described column plug stretches out bottom lid through through hole, is provided with and is communicated with outside air drain in column plug, on body, be provided with the suction mouth that can automatically close be communicated with this air drain, by this suction mouth, the gas of tank interior extracted out.
Furthermore, in technique scheme, described column plug is arranged perpendicular to body bottom surface, and the end in column plug is provided with the spacing preiection limiting column plug and exit from through hole.
After adopting technique scheme, the utility model has following beneficial effect compared with prior art: the utility model offers a through hole on lid, and by one with the seal cover cap of suction mouth, bled to tank interior by an apparatus for vacuum producing, gas is discharged by air drain and suction mouth; After vacuumizing tank interior, can preserve the product be contained in tank body better, making it, fresh-keeping it is longer, is not easy to go bad; And the body upper and lower surface of seal cover cap is designed to sucker shape, can allow body well with lid sealing, and excellent sealing between air extracting pump and body can be made, make to bleed and can carry out smoothly.

Detailed description of the invention:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
See Fig. 1-6, the improved structure of seal cover cap, comprise: a tank body 1 and the lid 2 be installed on tank body, lid 2 is offered the through hole 20 of connection tank body 1 inside, through hole 20 is provided with a seal cover cap 3, described seal cover cap 3 comprises: a body 31 and the column plug 32 perpendicular to body 31, and described its bottom surface of body 31 is set to sucker shape, to be adsorbed in the surface of inner cap 21; Its upper surface of body 31 is set to sucker shape equally, is reverse sucker shape.
Described column plug 32 stretches out bottom lid 2 through through hole 20, be provided with in column plug 32 and be communicated with outside air drain 33, the suction mouth 34 that can automatically close be communicated with this air drain 33 is provided with on body 31, by this suction mouth 34, the gas of tank body 1 inside is extracted out, column plug 32 is arranged perpendicular to body 31 bottom surface, and the end in column plug 32 is provided with the spacing preiection 321 limiting column plug 32 and exit from through hole 20.
Using method of the present utility model is as follows:
First, food is put into tank body, cover lid 2, tank body 1 is sealed.Then, bled by small-sized air extracting pump, pump head is aimed at body 31, bled by body, gas is arranged outward by air drain, gas passes air drain 33 and washes suction mouth 34 under the effect of air pressure open and discharges, and has been vented final vacuum suction inlet 34 and has automatically closed, and prevents air from entering tank body 1 inner.The body upper and lower surface of seal cover cap is designed to sucker shape, can allow body well with lid sealing, and excellent sealing between air extracting pump and body can be made, make to bleed and can carry out smoothly, thus, after carrying out suction vacuum to tank body 1 inside, the anti-article terminated in body 1 can be preserved better.
Certainly, the foregoing is only specific embodiment of the utility model, be not limit the utility model practical range, all equivalences done according to structure, feature and principle described in the utility model claim change or modify, and all should be included in the utility model claim.
