The cupulate bowl of shape.
In one or more embodiments of the invention, a fixinig plate is installed in the groove, the fixinig plate is set to institute
It states between check valve patch and groove, third through-hole corresponding with the first through hole is offered among the fixinig plate.It is i.e. described
First through hole, third through-hole and the second through-hole are coaxial arrangement.
In one or more embodiments of the invention, the fixinig plate is nylon6 chips.
In embodiments of the invention one or more, the fixinig plate and lid be by mold together with sulfidization molding, protect
Demonstrate,prove the stability of fixinig plate.
In one or more embodiments of the invention, check valve patch bottom surface is equipped with adhesive-layer, passes through the viscose glue
Layer is adhesively fixed on the fixinig plate.Check valve patch sticks at nylon fixinig plate upper surface, and fixinig plate will not be with silicon when use
Glue lid stretcher strain, to realize the requirement that check valve firm pasting will not fall off.
In one or more embodiments of the invention, the internal layer diaphragm and outer layer diaphragm are PE film.
In one or more embodiments of the invention, the thickness of the internal layer diaphragm is greater than the thickness of the outer layer diaphragm.
Outer layer diaphragm is relatively thin, conveniently picks up.
In embodiments of the invention one or more, the notch is that arc strip is poroid, and the notch be it is multiple, be in
Camber line arrangement.
In one or more embodiments of the invention, the lid lower edge is outward extended with several ears.Conveniently lift out
Lid or aperture tying up line.
Beneficial effects of the present invention:
Vacuum-pumping fresh-keeping cover of the invention, good using silica gel material sealing effect, reusable, lid is flexible applicable
The containers such as different size cupulate bowl of different shapes, it is flexible and convenient to use；The check valve for the vacuum-pumping being sticked is covered using silica gel
Patch is extracted out the air in container from check valve with aspiration pump, makes to extend the guarantor of food in vacuum state inside container
It is the fresh time limit, simple to operate, very practical；In addition, the diaphragm and outer layer of the check valve patch by internal layer aperture
Quit a post and thus leave it vacant diaphragm is bonded, and structure is simply at low cost；Fixinig plate is to be integrally formed with lid, and when installation only need to be by check valve patch
It is attached on fixinig plate, installation is simple, high production efficiency.

Specific embodiment
As follows in conjunction with attached drawing, application scheme is further described:
Referring to attached drawing 1-6, a kind of fresh-keeping cover of vacuum-pumping, the lid 1 is circular silica gel lid, has elasticity, the lid 1
It is equipped with groove 11, the groove 11 is by the land circle of a protrusion molding on lid 1 at the centre of groove 11 offers first
Through-hole 12.It is installed with a fixinig plate 2 in the groove 11, is offered among the fixinig plate 2 corresponding with the first through hole 12
Third through-hole 21.The fixinig plate 2 be nylon6 chips, with lid 1 be by mold together with sulfidization molding.It is embedded in the groove 11
There is a check valve patch 3,3 bottom surface of check valve patch is equipped with adhesive-layer 31, is adhesively fixed by the adhesive-layer 31 in institute
It states on fixinig plate 2.
The check valve patch 3 includes internal layer diaphragm 32 and outer layer diaphragm 33, and the internal layer diaphragm 32 is PE film, described outer
Tunic piece 33 is clear PE film, and the thickness of the internal layer diaphragm 32 is greater than the thickness of the outer layer diaphragm 33.Internal layer diaphragm
32 and outer layer diaphragm 33 bonded by non-drying glue layer 34.
The centre of the internal layer diaphragm 32 offers second through-hole corresponding with the first through hole 12, third through-hole 21
35, i.e., the described first through hole 12, third through-hole 21 and the second through-hole 35 are coaxial arrangement.The outer layer diaphragm 33 deviates described
The region of two through-holes 35 is set there are three notch 36, and the notch 36 is that arc strip is poroid, and arranges in camber line.
1 lower edge of lid is outward extended with several ears 13, conveniently lifts and uncaps or aperture tying up line.
Referring to figs. 5 and 6, in use, first with the elasticity that silica gel is had by oneself, the lid of lid 1 is located on container 5, makes to cover
Body 1 and container 5 form air-tight state.The unidirectional outlet principle of check valve is recycled, is adjacent to check valve patch outer surface with pump bowl 4
When pumping, when check valve patch 3 reaches cracking pressure when pumping, valve opening is specially equipped with the outer layer diaphragm of notch 36
33 are partially separated by negative pressure and internal layer diaphragm 32, as shown in fig. 6, arrow is air direct, outer layer diaphragm 33 is in heaving at this time
Outer connected state, inner air is by the second through-hole 35 of check valve patch 3, then from the notch 36 of outer layer diaphragm 33 by pump bowl
4 take away.After inner air is pumped, pump bowl 4 stops pumping, and outer layer diaphragm 33 is in power such as internal negative pressure, gravity, plastic resiliences
Under effect, by non-drying glue layer 34 and 32 automatic bonding of internal layer diaphragm, at this time it is enclosed first through hole 12 and third through-hole 21,
Vacuum state inside being formed.And under vacuum state, silica gel lid 1 is also bonded more closely with 5 edge of container.
It is that above-mentioned preferred embodiment should be regarded as application scheme embodiment for example, all with application scheme thunder
Same, approximate or technology deduction, replacement, improvement for making based on this etc., are regarded as the protection scope of this patent.
