Description

Manually push the vacuum sealed fresh-keeping box

Technical field

The utility model relates to a kind of structural development of manually pushing vacuum sealed fresh-keeping box, especially its vacuum sealed display film.

Background technology

It is more to have the known configurations of manually pushing vacuum crisper now, a kind of hand vacuum crisper is disclosed such as Chinese patent 96206090.9, form by box body, lid, seal ring, the intake and exhaust control setup is installed on lid, and can send the sound of " pouncing on ", prompting inlet and outlet situation.

Chinese patent 97241858.X discloses a kind of vacuum crisper for another example, by box body, lid, seal ring, stop pad, renovate, stop lid etc. forms, it makes exhaust formation vacuum in the box body manually gently to press lid, makes the stop pad close sealing by bar pressure then, reaches the vacuum freshness retaining purpose.

Above crisper has all been realized and need not just can have been vacuumized the purpose that reaches fresh-keeping by extra air extractor, but its vacuum seal film is a flat diaphragm, relies on its flexural deformation to realize vacuum seal, as shown in Figure 8, can not show vacuum state intuitively.

So, there is the people to invent again and a kind ofly can indicates container vacuum state crisper, a kind of tea and food fresh keeping storage vessel are disclosed such as Chinese patent 99253000.8, it is to add seal cover cap on the container body mouth; Cover or bulk container top on vacuum indication film is arranged, roof has aspirating hole to connect extraction pipe, is attached at pipe close on the pipe with pipe clamp and with tie on the pipe, and bleeding, to finish be that available pipe clamp and pipe close are airtight, and can often observe the container vacuum condition, its weak point is to cooperate air extractor to use.

Also have the people to above-mentioned known technology further combined with, occurred manually by pressure energy indication container vacuum state crisper, such as Chinese patent 02160431.2 and 200320108228.X, its vacuum shows that film is a hemispherical diaphragm, but that it finishes the needed deformation quantity of sealing is bigger, as shown in Figure 9, its upset stroke is L2, its upset stroke is bigger, easily because of the slowly resilience not in place of overturning, makes it effectively to keep sealing; Simultaneously, its hemispherical diaphragm is connected in the top side of diaphragm seal lamellar body, vacuum inhale and the time, fatigue damage easily.

Summary of the invention

The purpose of this utility model is at the problems referred to above, provide a kind of simple in structure, easy to use, can effectively keep sealing, the reliability and durability vacuum sealed fresh-keeping box of manually pushing.

The purpose of this utility model is achieved in that its box body and lid are salable and combines; Lid is provided with the groove of an air extractor vent, and air extractor vent extends upward and suit one sealing member; Be hinged with at an end of groove and renovate, be snapped with stop lid on renovating, at the interior shoulder upper limit of stop lid one vacuum sealed display film that can fit with the upper surface of sealing member is arranged, vacuum sealed display film comprises that diaphragm seal lamellar body and vacuum show film; Vacuum shows that film is that a bottom side from the diaphragm seal lamellar body extends upward and the circular cone stage body that spins upside down of moulding.

The utility model, circular cone stage body and diaphragm seal lamellar body are generally with high, with reduce vacuum show film suction and or the stroke of resilience, guarantee effectively to keep sealing.

The utility model can be provided with at least one circle and return the power muscle on the end face of circular cone stage body, when discharging vacuum, help the resilience that vacuum shows film.

The utility model, vacuum show that film is provided with a rounding groove from upwardly extending end, the bottom side of diaphragm seal lamellar body, make vacuum show film suction and or resilience reliability and durability.

The beneficial effects of the utility model are: it is directly perceived to vacuumize effect, vacuum show film suction and or the stroke of resilience short, can effectively keep sealing and reliability and durability.Therefore, the utility model, have simple in structure, easy to use, can effectively keep sealing, reliability and durability advantage, can cooperate fridge freshness retaining refrigeration, micro-wave oven or place overhead dish-washing machine to use.

Following embodiment accompanying drawings is further described the utility model.
