Description
Technical field
The utility model relates to container, particularly relates to a kind of suction pressure seal box.
Background technology
At present, the application of lunch box is more and more universal, no matter the student gone to school or the working clans in work, middle westerly zone part dish, band part meal are all ordinary affair, but mostly structure due to dish box used is at present that box body adds box lid type, although manufacture fairly simple, sealing property is all not good enough substantially, if and lunch box is placed in bag and is also easy to spill vegetable soup, take separately again inconvenient with hand; Authorization Notice No. is CN201512186U, patent name is that the Chinese utility model patent of " suction pressure seal box " is for solving sealing problem, propose a scheme: on lid, be provided with the port lid corresponding with described pore, port lid is flexibly connected with lid, and port lid is provided with the stopple corresponding with described pore; Although the program solves sealing problem, there is following problem in said structure: 1, leak tightness is unstable in use, if the temperature of the inside is too high, stopple coordinates not tight with pore, cause gas leakage, internal temperature is reduced, poor sealing; 2, this structure mesoporous lid is movable connection with lid, finds out from accompanying drawing, and as opened, port lid need be started, then stopple leaks outside cruelly, is easy to dust stratification dirt; 3, because port lid and lid are connected by axle, under open mode, port lid and lid on a plane, are not easy to suffer damage, and cause service life short.
Utility model content
In order to solve problems of the prior art, the utility model provides a kind of suction pressure seal box, and good seal performance, health, structure are simple, and the life-span is long.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of suction pressure seal box, it is mainly made up of negative pressure ventilation valve, lid, box body and silica gel sealing ring, lid covers on box body, sealed by silica gel sealing ring, described lid top is provided with through hole, negative pressure ventilation valve to be arranged in through hole and to closely cooperate with through hole, and the structure of described negative pressure ventilation valve is: top is the Handheld Division with multiple camber line concaved; The middle sealing for making connection for bbreather pipe be in closure state, sealing is made up of the cylinder of the upper cover that periphery is provided with flange collar, diameter is greater than Handheld Division and below; Below is for being along the circumferential direction distributed with the ventilating part of some vent grooves, and be orientation angle below ventilating part, its vent grooves is between adjacent two orientation angles.
Further, in order to realize being tightly connected between lid and box body, the structure of described lid and box body junction is, the bottom of described lid is along the circumferential direction provided with circle groove down near outside, silica gel sealing ring is arranged in groove.
Further, come off to prevent silica gel sealing ring of long duration, described suction pressure seal box also comprises compressing tablet, the structure of this compressing tablet is intermediate projections, and both sides are horizontal stopper, and described compressing tablet is arranged on the inner side of silica gel sealing ring, centre portion inserts in groove, side stopper is positioned at below silica gel sealing ring, and opposite side stopper is positioned at below the madial wall of groove, and this compressing tablet by silica gel sealing ring card in a groove.
The utility model has following beneficial effect relative to prior art:
(1) setting of compressing tablet, makes to be connected between silica gel sealing ring with lid closely, difficult drop-off, better tightness;
(2) negative pressure ventilation valve middle seal is designed to periphery with flange collar, and the inner structure forming cavity, makes better tightness, avoid simultaneously and because air pressure inside is excessive, connection for bbreather pipe is upspring;
(3) below of negative pressure ventilation valve is along the circumferential direction distributed with some vent grooves, and negative pressure ventilation valve can be realized then to be in opening to pull-up, by its by earth then whole product be just in sealing state, simple to operate;
(4) negative pressure ventilation valve realizes sealing by pull-up, pressing, and contacting foodstuff place can not, by external contamination, use much cleaner.

Detailed description of the invention
As shown in Figures 1 to 6, the utility model relates to a kind of suction pressure seal box, it is mainly by negative pressure ventilation valve 1, lid 2, box body 3 and silica gel sealing ring 4 are formed, lid 2 covers on box body 3, described lid 2 with the structure of box body 3 junction is, the bottom of described lid 2 is along the circumferential direction provided with circle groove 21 down near outside, silica gel sealing ring 4 is arranged in groove 21, compressing tablet 5 is arranged on the inner side of silica gel sealing ring 4, the structure of this compressing tablet 5 is intermediate projections, both sides are horizontal stopper, centre portion inserts in groove, side stopper is positioned at below silica gel sealing ring 4, opposite side stopper is positioned at below the madial wall of groove 5, silica gel sealing ring 4 is stuck in groove 21 by this compressing tablet 5, wherein, lid 2 top is provided with through hole 21, and negative pressure ventilation valve 1 to be arranged in through hole 21 and to closely cooperate with through hole.
As shown in Figures 1 to 3, the structure of described negative pressure ventilation valve 1 is: top is the Handheld Division 11 with multiple camber line concaved; The middle sealing 12 for making connection for bbreather pipe be in closure state, sealing 12 is made up of the cylinder 122 of the upper cover that periphery is provided with downward flange collar 121, diameter is greater than Handheld Division 11 and below; Below is for being along the circumferential direction distributed with the ventilating part 13 of some vent grooves 131, and be orientation angle 132 below ventilating part 13, its vent grooves 131 is between adjacent two orientation angles 132.
As Fig. 4 institute scholar, when negative pressure ventilation valve 1 is in open mode, through hole 21 place of lid is just in the below of the ventilating part 13 of negative pressure ventilation valve 1, due to the design of orientation angle 132, make negative pressure ventilation valve 1 can not depart from lid 2 completely, now, the vent grooves 131 between 3 orientation angles 132 of negative pressure ventilation valve makes there is gap between connection for bbreather pipe 1 and lid 2, and lid 2 can easily cover on glass cartridge 3.
Fig. 5 is that suction pressure seal box lid and box body cover constitution diagram, now, together with described lid 2 to be covered with glass cartridge 3 closely by silica gel sealing ring 4, under effect due to compressing tablet 5, silica gel sealing ring 4 can not loosen easily, good airproof performance, now, negative pressure ventilation valve 1 is in open mode, and therefore air can be flowed by vent grooves 131, and this kind of state seal box can be put into micro-wave oven or baking box heats.
Fig. 6 is that suction pressure seal box is in sealing state, now negative pressure ventilation valve 1 and lid 2 are in closure state, wherein the cylinder 122 of negative pressure ventilation valve closely cooperates with through hole 21, and the flange collar 121 of its sealing 12 fits tightly with lid 2, a cavity 124 is formed before flange collar and lid, due to the existence of cavity 124, make the better tightness of negative pressure ventilation valve 1, can not be excessive and upspring because of the air pressure in box body; Now, the air in glass container and the external world are states of isolation, can reach heat insulation effect.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments, and these belong to spirit institute's apparent change of extending out of the present utility model or change and are still among protection domain of the present utility model.
