Description

The manual vacuum antistaling container

The utility model relates to a kind of vacuum freshness retaining container.

Vacuum crisper of the prior art, its structure comprises box body, lid, hand pulling type vacuum pump, duck-beak type seal valve piece is equipped with at the lid middle part, the piston of pump in a tubular form, wherein and a valve arranged, have following weak point in the use: 1, normal duck-beak type valve gas leakage above cover enters in the crisper, thereby can not reach the preservation of expection; 2, owing in the pipe of drawing together plug a ball valve being arranged, can not move smoothly sometimes, produce skidding when causing exhaust; 3, the duck-beak type valve is long object, so long part is protruded at the place in the middle of below fresh-keeping cover, influence attractive in appearancely, cause raw-material waste again, moreover reduced the space in the crisper and used volume, 4, some foods have liquid, but need separate, in existing technology, can't accomplish, if deposit the less food of particle, when exhaust, can be inhaled into duck-beak type valve place, make valve can not normally close influence and use; 5, do not have mark and date calibration in the prior art, the user does not often remember clearly and deposits date or extraction date.

The purpose of this utility model just is to provide a kind of more reasonable structure, sealing property is better, operation is more reliable and can realize the manual vacuum antistaling container of date stamp.

The purpose of this utility model is achieved in that a kind of manual vacuum antistaling container, comprise box body, lid, vacuum pump, a seal valve piece is equipped with at said lid middle part, one square is housed between said lid and the box body, said lid outer ring indicates date calibration, mark is carved with in the upper edge of corresponding box body, said seal valve piece outer is the circle shape, the centre is convex disk, said outer and disk are linked by stem, the straight trough that the middle part of said lid has a circular groove that matches with above-mentioned outer and matches with above-mentioned stem, circular groove is with the interior through hole that has, and the piston ring above the piston groove in the said vacuum pump axially has a hole.

Below in conjunction with embodiment (accompanying drawing) the utility model is further described.

Fig. 9 is A among Fig. 8-A cutaway view.

The utility model manual vacuum antistaling container, comprise box body 1, lid 2, vacuum pump 3, a seal valve piece 4 is equipped with at said lid middle part, one square 5 is housed between said lid and the box body, said lid outer ring indicates date calibration 6, mark 7 is carved with in the upper edge of corresponding box body, said seal valve piece outer 8 is the circle shape, the centre is convex disk 9, said outer and disk are linked by stem 10, the straight trough 12 that the middle part of said lid has a circular groove 11 that matches with above-mentioned outer and matches with above-mentioned stem, circular groove is with the interior through hole 13 that has, and the piston ring above the piston groove in the said vacuum pump axially has a hole 14.

Said square is a disk shape, one boss ring 15 is arranged at the bottom, the centre has hole 16, the outer has two semicircle orifices 17, mouth is provided with one convexly along 18 on the said box body, and the outer of said lid is downward, and outer bead is provided with a circular groove 19, in the middle of the circular groove square-section seal ring 20 is set, the number of the stem in the said seal valve piece is two or three.

The utility model operating process is as follows: will treat that fresh-keeping material packs in the box body, the material of depositing moisture content or having liquid to ooze out needs square is placed on the bottom of material, if deposit the less or fuller material of material square should be placed on material above, then lid is closed, the mark (can be set to triangle) of date calibration respective aligned box body is deposited the date to show, aiming at the seal valve piece with hand-operating vacuum-pump presses down gently, another hand catches the piston handle back and forth to draw several air exhaustion that can make down in the box body, make it to be in vacuum state, deposit the purpose that material reaches long-period freshness preserving thereby make.

The utility model compared with prior art has the following advantages:

1, the seal valve piece after employing improves etc., more reasonable structure, sealing property is better;

2, the vavuum pump of no ball-valve structure operates more reliable;

3, can realize date stamp, use more convenient.
