Description
Technical field
The present invention relates to a kind of vacuum sealed fresh-keeping container, the antistaling container of especially a kind of vacuum-pumping and good seal performance.
Background technology
The structure of existing sealing crisper is more, for example, China Patent No. 200420020959.3, a kind of sealing crisper that is used for seasoning food is disclosed, a rectangular box body is arranged, the lid that matches is installed on box body, its lid connects sealing member and box lobe, and is shaped on internal sealed ring under lid, is shaped on outer seal ring under the sealing member, the internal sealed ring of lid matches with box mouth inwall, sealing member matches with the box mouth end face of box body, and the outer seal ring of sealing member matches with box mouth outer wall, is shaped on grab under the box lobe, outer wall at box body is shaped on convex tendon, and grab and convex tendon are interlocked; Be characterized in the sealing of three places being arranged at the box body oral area, the one, the internal sealed ring of lid and box mouth inner wall sealing, the 2nd, sealing member and the sealing of box mouth end face, the 3rd, the outer seal ring of sealing member and the sealing of box mouth outer wall; And sealing back, three places is interlocked by the grab of box lobe and box body convex tendon and fixes, and has increased sealing reliability; This have the crisper of triple seal at the box body oral area, though its leak tightness is better, its structure is also complicated, the manufacturing cost height, the purpose made convex tendon is arranged on the box body that is adopted, need and the box lobe on grab be interlocked and supportingly become integral body to use, thereby range of use is restricted.
For another example, International Patent Publication No. WO 2004113194, a kind of cover for sealed container is disclosed, comprise fexible film and elastic membrane two parts, this elastic membrane is used for the wall of airtight container, this elastic membrane has an expandable opening on container top, so just go for the container of various difformities and size; Identical with traditional approach, this container cover also provides a liner.But because this container cover is disposable, thus easily cause the wasting of resources and cause environmental problem, and also when storing soup juice food, soup juice can ooze out accidentally.
And for example, International Patent Publication No. WO 2005021396, a kind of container cover is disclosed, it comprises: have the cover plate and the ring seal member of the rear surface that is used for contacting container, this member has the rear perimeter edge partial fixing peripheral part on the cover board and the retaining part that detachably and flexibly contacts the rear surface of cover plate along cover plate.Container cover can irrespectively be applied on the container with the type or the size of container.This container cover is owing to being connected with container easily and taking apart, so easy to use.Because this container cover is not disposable, so can not cause the wasting of resources or cause environmental problem.But, not ideal because of its sealing property when using on the irrelevant container of all kinds or size, so it is shorter to seal fresh keeping time, be necessary to improve.
Summary of the invention

The specific embodiment
Embodiment 1, circular vacuum sealed fresh-keeping container
Referring to figs. 1 through Fig. 8, present embodiment 1 comprises lid 1, vessel 2, and lid is connected by elastic sealed body 3 with vessel; Elastic sealed body comprises back seal circle 31, lid seal ring 32 and lower seal 33, and back seal circle, lid seal ring and lower seal are shaped to one via an injecting glue; The lid seal ring is gone along with sb. to guard him by last grommet type seals 321, following ring washer 322 and lid surrounded by edges wall 323 and is constituted open slot 324, and the edge 11 of lid and open slot sealing interlocking constitute seal cover cap by lid and elastic sealed body; From the make progress portion that spins upside down 311 of the back seal circle that the extended arc cell wall of one forms of lid surrounded by edges wall, the portion that spins upside down 331 of the lower seal that forms from the extended folding of the downward one of lid surrounded by edges wall shape cell wall; Flexible sealing valve 4 is set on lid 1, through hole 12 snappings on the buckling parts 41 of flexible sealing valve by its lower end and the lid, and the edge 42 of flexible sealing valve covers the pore 13 on the lid, and the pore 13 on the lid is arranged in the mode 15 of circumference array; Release vacuum hand is set on flexible sealing valve 4 holds 43; Flexible sealing valve 4 is arranged at the depressed part 14 on the lid; Elastic sealed body 3 and flexible sealing valve 4 adopt the silica gel material; Back seal circle 31 and lower seal 33 are provided with arc upset shirt rim 312,332; This arc upset shirt rim 312,332 is provided with strengthens convex tendon 313,333.
The present invention, the peripheral shape of elastic sealed body can be and the Any shape of vessel form fit, be not limited to above-mentioned these mentioned shapes.
Use of the present invention and principle of work are described in detail as follows:
With reference to Fig. 3, Fig. 4, Fig. 5, Fig. 6, the open slot 324 sealing interlockings of the edge of lid 11 and elastic sealed body 3, constitute seal cover cap by lid and elastic sealed body after, upwards upset of lower seal 33 is the edge of seal cover cap aligning vessel 2; Lower seal 33 is overturn downwards, lower seal 33 is opened direction D along lower seal again
1, D
2Outer wall towards vessel 2 opens, and lower seal 33 coats banding on the outer wall of vessel 2; Then, back seal circle 31 overturns downwards along the diagram direction of arrow, and back seal circle 31 also coats banding on vessel 2, forms the double-layer sealing structure of back seal circle 31 and 33 pairs of vessels 2 of lower seal, and the result as shown in Figure 8.
With reference to Fig. 3, the flexible sealing valve that manual pump bowl is aligned in the depressed part setting on the lid is operated, air in the vessel is upwards discharged towards the direction of arrow, and the lid cambered surface is recessed, shows the degree that vacuumizes, at this moment, stop to vacuumize, because bar pressure is poor, the edge of flexible sealing valve compresses and covers pore on the lid, and the vacuum state of maintenance container, the result is as shown in Figure 4.
With reference to Fig. 4, when taking food, the release vacuum hand of pulling flexible sealing valve holds 43, discharges vacuum, and the lid cambered surface is recovered state of nature; Upwards overturn back seal circle 31 and lower seal 33, seal cover cap can take away.
The present invention, can also mark the calendar scale by the depressed part on lid, during fresh-keeping and cold storage, rotation discharges the vacuum hand and held for 43 sensing dates on the same day, when take out the refrigeration back,, deduct fresh-keeping and cold storage and set the date pointed according to the date of taking out the same day, just know to have refrigerated several days, effectively avoid effective period of food quality.
