Description
Technical field
The present invention relates to container, particularly a kind of suction type automatic-sealed container.
Background technology
Container, when storing food, need to seal fresh-keepingly, is conventionally all by corresponding helicitic texture being set on container and lid with screwing hermetic, and such structure is tradition and be difficult to adapt to nonmetallic vessel too, also cannot directly be placed in micro-wave oven and heat.
Summary of the invention
In order to address the above problem, the invention provides a kind of suction type automatic-sealed container.
The technical solution adopted in the present invention is: a kind of suction type automatic-sealed container, include the container of opening, it is characterized in that, also comprise seal cover cap, the corresponding container inner wall of seal cover cap is provided with downward sealed wall, and sealed wall is provided with seal groove, and seal groove inner sleeve has seal ring, when seal cover cap covers on container, seal ring is adjacent to container inner wall; On seal cover cap, also have seal, seal is positioned on sealed wall and seal and is plugged with sealing plug;
Sealing plug is mushroom, by card division, piston part and umbrella shape arc top, is connected to form successively from lower to upper, and fill in seal piston part; Wherein, card division the widest part is 101～140% of seal the widest part length, and piston part cross-sectional area is less than seal cross-sectional area; Umbrella shape arc top is greater than seal, and is provided with a plurality of lower protruding fore-sets at umbrella shape arc top inside face, leaving certain gaps uncovered by the economic plan between fore-set, and between the edge that fore-set pushes up at seal and umbrella shape arc, and fore-set lowest part during normal condition should be higher than umbrella shape arc top edge.
Described fore-set is and the corresponding arc shape of umbrella shape arc top edge.
Described card division and piston part have air channel.
Described air channel is corresponding with the breach between fore-set, umbrella shape arc top is also provided with same lower protruding reinforced rib, every reinforced rib two ends join to a side that should end points with a side point of fore-set and air channel and joint, umbrella shape arc top respectively, make air channel, reinforced rib and fore-set breach form venting channels.The present invention even can be made as whole lower convex by reinforced rib and the folded umbrella shape arc of fore-set top bit, to highlight venting channels.
Described sealing plug and seal ring are all made by silica gel.
Described seal ring is provided with outward extending sealing sheet, and when seal cover cap covers on container, sealing sheet is adjacent to container inner wall, the ability that adapts to container inner wall shape for expanding it.Described sealing sheet is also made by silica gel.
Described container is ceramic bowl or ceramic pot etc.
Being shaped as of described container is square or circular etc.
When container of the present invention will seal, directly by under seal cover cap lid, air squeezes out from umbrella shape arc top edge by seal, until air is overflowed too much, in container, form negative pressure, extraneous air is even pressed on the edge on umbrella shape arc top on lid and (now after the edge pressurized on umbrella shape arc top, forms the relative distortion that upwarps compared with inside line, the sealing plug umbrella shape arc top of therefore making with silica gel can be wanted reinstatement and produce a kind of application force pressing down because of its edge, with extraneous air combined action intensified pressure), form sealing, during uncap, on lid, carry, it is large that space in lid becomes, container internal gas pressure diminishes, extraneous air becomes large to the pressure on umbrella shape arc top, sealing plug is pressed further in container, umbrella shape arc top edge is adjacent to the constantly inwardly expansion of scope of lid, until fore-set is also pressed down and is adjacent to lid, now fore-set just plays the effect of lever, on the contrary by the umbrella shape arc top edge position perk in fore-set outside, make umbrella shape arc top produce distortion, air outside the container just breach between fore-set enters container from seal, container inner air and outer air is communicated, pressure is eliminated, lid is just easy to open.Equally, when filling food putting into microwave-oven-heating in container, after air in container is heated, can directly the umbrella shape arc of sealing plug be backed down, container inner air and outer air is communicated, removal internal pressure, need not open the effect that seal cover cap just can reach ventilation pressure release, and this container can be used equally in micro-wave oven.
The setting of reinforced rib, makes air channel, reinforced rib and fore-set breach form venting channels, can avoid umbrella shape arc top distortion sometimes excessively to seal breach, the situation that the inside and outside air of container cannot be communicated.
Structure of the present invention arranges simple and practical, and sealing plug can be along with under the lid of lid or open and automatic-sealed or open, and without manual control, and can directly be placed in micro-wave oven and heats, and fully meets people's user demand.
