Description

The damp-proofing and fresh-keeping container

The utility model relates to a kind of vacuum freshness retaining container, particularly a kind of damp-proofing and fresh-keeping container that is provided with vacuum suction device.

As everyone knows, the method for optimal preservation food or article makes it not impaired for a long time and does not make moist, and makes it to place vacuum state exactly.Yet environment is become the vacuum attitude, and not only difficulty but also investment are big, and therefore, common people are difficult to accomplish preserve food or article with vacuum.For fresh-keeping damp-proof food of needs or article, put into desiccant after generally it being put plastic bag or vanning, but because packing material contains a large amount of air, therefore, this fresh-keeping damp-proof method can not prevent from effectively to make moist and fresh-keeping.Now comparatively the way of science is that food or article are placed in the airtight container, and with the air extraction in the container, reaches the purpose that vacuum state is realized damp-proofing and fresh-keeping in the container thereby make.Promptly belong to this type of as No. 220262 patent in Taiwan " vacuum freshness retaining jar structure ", still, this apparatus structure complexity, assembling, dismounting bother time-consuming, the manufacturing cost height, the speed of evacuation is slow, efficient is low, and face shaping is not good.

The purpose of this utility model provides very simple, easy to loading and unloading, the damp-proofing and fresh-keeping container rapidly of bleeding of a kind of structure.

The purpose of this utility model is achieved in that it comprises that one is carried out the leak free lid for the vessel of storing products and one with this vessel; It is characterized in that lid portion inside is provided with the sky chamber, side direction is provided with the breach of reservation shape; In the indoor cylinder chamber that links to each other with breach that laterally is provided with of sky, the front end of cylinder chamber is provided with the deflation hole that is communicated with empty chamber, the rear end is provided with the unidirectional induction opening that is communicated with the outside, lid bottom surface, be provided with a piston body in the cylinder chamber, promote the reciprocating axostylus axostyle of piston body, and link to each other, be positioned at cylinder chamber's spanner outside and that adapt with notch geometry with the axostylus axostyle end.

In unidirectional induction opening, be provided with and air is come out from container and can not make unidirectional non-return air valve in the air admission container.

End face at lid is provided with the air extractor vent that is communicated with the lid bottom surface, so that the usefulness of opening cover, this air extractor vent is by piston packing.

Promoting the reciprocating axostylus axostyle of piston rod is rectangle, is provided with the restrictions with the activity of restriction axostylus axostyle that adapts with the axostylus axostyle shape in the breach inboard.

Using method of the present utility model is: when food or other article being carried out damp-proofing and fresh-keeping when preserving, lid is opened, and will be waited that the thing of preserving puts into vessel, cover the opening of lid in vessel.At this moment, though lid seals container, the air that originally contained in the vessel still is sealed in the vessel, and it has disoperation to the thing that is saved, open spanner and back and forth pulling to make it to drive piston body reciprocating in cylinder chamber.So, the air of piston body back is drained in the sky chamber and through breach by the deflation hole of cylinder chamber's front end under the compression of piston body and overflows, simultaneously, piston body fwd air starvation forms negative pressure, and force the air in the vessel to enter into piston body fwd cylinder chamber by unidirectional non-return air valve, in so constantly back and forth, the air in the vessel is fewer and feweri, reaches at last to preserve the degree of vacuum that article need.

If when food that taking-up is saved from vacuum vessel or article, because the container external and internal pressure is poor, lid is difficult to take off from vessel.Therefore, must transfer to piston earlier from the air extractor vent of lid end face, it is poor to eliminate the container external and internal pressure that air is entered from air extractor vent in the container, and at this moment, lid will be taken off from vessel easily.

The utility model compared with prior art, its remarkable advantage is: 1. simple in structure, the assembling, convenient disassembly, low cost of manufacture; 2. bleed rapidly, easy to operate.The utility model extensively is suitable for preserving food or other article, has more successfully solved food or other article are collected fresh-keeping problem, is the ideal damp-proofing and fresh-keeping instruments in place such as family, room and kitchen.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that lid is along the axial cross-sectional view of cylinder chamber.

Fig. 3 is lid and the axial vertical cross-sectional view of cylinder chamber.

Fig. 4 is the utility model constitution diagram of bleeding.

Fig. 5 is the utility model deflated state figure.

Embodiment: the damp-proofing and fresh-keeping container that the utility model is made, it is made up of with the lid that covers mutually with it vessel, and extracting container body and lid are circular.Lid portion inside is empty chamber 1, and its periphery extends to form the spill annulus corresponding to the vessel peristome downwards.Side direction at lid is provided with a breach 2, laterally is provided with cylinder chamber 3 over against breach 2 in empty chamber 1.Front end in cylinder chamber 3 is provided with a deflation hole 4 that communicates with empty chamber 1, and the rear end is provided with a unidirectional induction opening 5 that communicates with the outside, lid bottom surface vertically downward.In unidirectional induction opening 5, be provided with a unidirectional non-return air valve 11, with the unidirectional air inlet of limit air.

In cylinder chamber 3, be provided with the piston body 6 of a tapered shape, its small bore end preceding heavy in section end after, in the hope of move forward and backward in the process effect that air is produced compression at piston body 6.In the rear end of piston body 6 and be axially arranged with an axostylus axostyle 7, extend to a terminal affixed spanner 8 of breach at axostylus axostyle 7, spanner 8 adapts with the shape of breach 2, so that breach 2 is suitably covered, is provided with one and draws the cavity that pushes away use for pointing to stretch into above spanner 8.For guaranteeing that axostylus axostyle 7 only makes axial motion, axostylus axostyle 7 is a rectangle, is provided with one in breach 2 inboards and forms the restrictions 12 that adapts with axostylus axostyle 7.

Be provided with an air extractor vent 9 that independently is communicated with the outside, lid bottom surface at the end face of lid, the mode that is used to seal this air extractor vent 9 is a lot, the sealing mechanism that is made of button and spring as employing.The utility model only adopts 10 pairs of air extractor vents of simple piston to seal here.No matter be the air intake that communicates with cylinder chamber 3 on the bottom surface of lid, still the air intake place that directly communicates with the lid end face is equipped with the material layer that one deck prevents that moisture content and impurity from passing through.
