Description

Fresh box for food

The utility model relates to food preserving box, more clearly says so in the family or food preserving box that whilst on tour is used for food fresh-keeping or carries.

Food fresh keeping mode in the past, a kind of is preservation by low temperature, for example the reefer of electric refrigerator.Its shortcoming, the one, the fresh-keeping time is short, and can only use at home, can not carry.Another kind is the pocket type vacuum freshness retaining, though can carry, it is disposable.As long as food bag one is opened, freshness protection package just can not re-use.

The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, but a kind of both long-period freshness preservings, use forever repeatedly, portable again dapper food preserving box are provided.

In order to achieve the above object, the utility model is by box body, can be fastened on the loam cake on the box body, the seal ring that is enclosed between loam cake and the box body constitutes.Loam cake central authorities have two cylinder-like structures of size, and wherein by adorning a rubber plug, the central authorities of rubber plug have a unidirectional valve opening.Unidirectional valve opening makes has air to be drawn out of in the box body, can not reversely flow to.The bottom of little cylinder-like structure has the hole, and the air in the box body can unobstructedly be drawn out of.The outside suit of little cylinder-like structure a plastic housing, and it can strengthen the rigidity of little cylinder-like structure, guarantees that exhaust is unimpeded, avoids stopping up pore.Rubber plug is used to vacuumize.Fasten or penetrate in the rubber plug with vacuum extractor, just vacuum-pumping.

The outside of rubber plug has the ring-type that can increase friction force or the shape of threads projection friction force with the roundlet tubular structure inboard that increases it and loam cake, makes it to be difficult for deviating from.Rubber plug is installed among two cylinder-like structures of size of loam cake, avoids protruding covering last, is easy to carry.

The outside of rubber plug can the pump bowl that can take off of a special use by suit, also can use other vacuum extractor to vacuumize.Pump bowl is by barrel shell cylindraceous.Be sleeved on hollow in the barrel shell and an end have division board, the outside trough of belt of this end, the other end have the tube core of deflation hole.Be fixed on the tube core handle of a core other end.Be installed in the unidirectional vent plug of the division board central authorities of a core, be installed in a core one end outer side slot seal ring interior and between outside barrel shell inboard and the tube core and constitute.

Pump bowl is enclosed within on the rubber plug, and pulling tube core handle is reciprocating.When upwards spurring, seal ring in the outer side slot of tube core has sealing function, pump bowl barrel shell lower lumen forms negative pressure, and unidirectional vent plug tightly is pressed on the division board of a core, and the draft of pump bowl enters the unidirectional valve opening of the air in the box body by rubber plug central authorities in the pump bowl barrel shell lower lumen.When with tube core handle when pressing down, the unidirectional valve opening of rubber plug central authorities is tightly shut by surrounding air, the high pressure gas in the barrel shell lower lumen can only enter in the inner chamber of a core and through the deflation hole exhaust to atmosphere by unidirectional vent plug.Back and forth the core handle of pulling for several times just can pump the air in the box body, forms vacuum, and food wherein just can be by fresh-keeping.When opening crisper, only need be used for rubber plug one is pinched gently, air just enters box body on every side from it, and loam cake just can be opened.The unidirectional valve opening of rubber plug and the unidirectional vent plug of pump bowl can be cracks, it can by the surrounding air of a side tightly jam-packed shut, also can be washed open by the high pressure air of opposite side.

Task of the present utility model comes to this and finishes.

The utility model can forever use repeatedly, and is easy to carry, and fresh keeping time is long.It can be widely used in the family or in the food fresh keeping of whilst on tour.Its fresh keeping time is identical with vacuum fresh-keeping bag in the past, reaches 4--10 its service life.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further explanation.

Fig. 1 is the structural representation of embodiment 1.

Fig. 2 is the structural representation of the special-purpose pump bowl of embodiment 2.

Shown in Figure 1, embodiment 1 is made of box body 5, loam cake 2, seal ring 3.Loam cake central authorities have two cylinders of size with structure 11 and 12, rubber plug 1 are installed wherein, rubber plug 1 central authorities have check valve hole 16, and the outside has annular projection 14, and roundlet tubular structure 12 bottoms are porose 15, outside suit plastic housing 4.Embodiment 1 can by special use or the general-duty vacuum extractor vacuumize.

Shown in Figure 2, embodiment 2 has special-purpose pump bowl, can be fastened on the rubber plug 1, also can take off.It has division board 15 by barrel shell 7, and the tube core 8 of deflation hole 16, tube core handle 6, unidirectional vent plug 9 and seal ring 10 constitute.

Embodiment 1 and embodiment 2 fresh keeping time are long, can use for a long time repeatedly, and are easy to carry, can be widely used in family and during the journey.
