Description
Technical field
The present invention relates to a kind of vacuum sealed display film of antistaling container use and the push-type vacuum fresh-keeping box of structural development thereof.
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 1, 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 it is bigger that it finishes the needed deformation quantity of sealing, as shown in Figure 2, vacuum shows that the upset stroke of film is L
1, 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, during vacuum engagement, and fatigue damage easily.
Summary of the invention
Main purpose of the present invention is at the problems referred to above, provide a kind of simple in structure, can effectively keep sealing, reliability and durability vacuum sealed display film.
Another object of the present invention is at the problems referred to above, provide a kind of simple in structure, easy to use, can effectively keep sealing, reliability and durability push-type vacuum fresh-keeping box.
Main purpose of the present invention is achieved in that a kind of vacuum sealed display film, comprises annular membrane lamellar body and plastic deformation film; The plastic deformation film is that a bottom side from the annular membrane lamellar body extends upward and the integrated circular cone stage body that can spin upside down along the bottom side of annular membrane lamellar body; The height of circular cone stage body equals the thickness of annular membrane lamellar body.With the adhesive of minimizing plastic deformation film or the stroke of resilience, guarantee effectively to keep sealing.
The present invention can be provided with one at least and enclose back the power muscle on the end face of circular cone stage body, when discharging vacuum, help the resilience of plastic deformation film.
The present invention, the plastic deformation film is provided with a rounding groove from upwardly extending end, the bottom side of annular membrane lamellar body, makes the adhesive of plastic deformation film or resilience reliability and durability.
Another object of the present invention is achieved in that a kind of push-type vacuum fresh-keeping box, and its box body combines with lid is salable; 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 annular membrane lamellar body and plastic deformation film; The plastic deformation film is that a bottom side from the annular membrane lamellar body extends upward and the integrated circular cone stage body that can spin upside down along the bottom side of annular membrane lamellar body; The height of circular cone stage body equals the thickness of annular membrane lamellar body.
The invention has the beneficial effects as follows:
1), the plastic deformation film is that a bottom side from the annular membrane lamellar body extends upward and the integrated circular cone stage body that spins upside down, so it is directly perceived to vacuumize effect, simultaneously, the one-body molded extension that makes progress from the bottom side of annular membrane lamellar body of its plastic deformation film, make the plastic deformation film when vacuum engagement, be not in tired strained condition; The hemispherical diaphragm that extends downwards from the top side that has fundamentally solved known design is in the irrationality of tired strained condition all the time when vacuum engagement, thereby has outstanding substantive distinguishing features and more durable significant good effect;
2), the upset stroke of plastic deformation film is L
2, the upset stroke L of plastic deformation film
2The upset stroke L that shows film much smaller than known vacuum
1, this just effectively reduces the adhesive of plastic deformation film or the stroke of resilience, thereby is easy to sealing, and can effectively keep sealing;
3), on the end face of circular cone stage body, can be provided with one at least and enclose back the power muscle, when discharging vacuum, help the resilience of plastic deformation film;
4), the plastic deformation film is provided with a rounding groove from upwardly extending end, the bottom side of annular membrane lamellar body, makes the adhesive of plastic deformation film or resilience reliability and durability.
Therefore, the present invention, 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.
The present invention is further illustrated for following embodiment accompanying drawings.
