Description

Sealable tank

Technical field

The utility model relates to a kind of sealable tank.

Background technology

The cover of existing sealable tank is provided with sealing member, if sealing member is too tight, cover is pressed into and takes out too effort, if sealing member is too loose, then can not effectively seal.

Summary of the invention

The purpose of this utility model is at the problems referred to above, and a kind of leak free sealable tank simple in structure, easily manufactured, laborsaving, effective is provided.

The purpose of this utility model is achieved in that and comprises that cover, tank body and sealing member, cover are provided with the Gai Yuan at top that lid connects tank body, and cover is to being arranged with inner barrel, and sealing member is the flexible sealing dish that is arranged on the inner barrel; Surround between exhaust area by Gai Yuan, inner barrel and flexible sealing dish three, offering between the connection exhaust area on the barrel of inner barrel and the deflation hole of tank body inboard.

The utility model, the flexible sealing dish is captiveed joint for the injection mo(u)lding disjunctor with the preferred connection mode of inner barrel; Like this, shaped article need not manually assemble the flexible sealing dish again on cover.

The utility model, inner barrel are provided with for flexible sealing dish injection moulding bonded assembly preformed hole, in the inwall injection mo(u)lding simultaneously of inner barrel the flexible sealing dish inner covering of captiveing joint with the inwall disjunctor of inner barrel are arranged; Like this, inner covering and flexible sealing dish embrace jointly and disjunctor is fixed in inner barrel, even also can not break away from after the repeatedly stressed use of flexible sealing dish.

The utility model in the bottom of inner barrel, is provided with the steady ring with the inwall of tank body coupling; Like this, be convenient to that the location covers cover and loosening.

The utility model owing to adopt the structure of flexible sealing dish and the injection moulding of cover disjunctor, need not manually assemble, and the flexible sealing dish is also solid and reliable; And, be communicated with between exhaust area and the deflation hole of tank body inboard owing to be provided with, cover is pressed into and takes out very laborsaving; Thereby, the utlity model has leak free advantage simple in structure, easily manufactured, laborsaving, effective, be applicable to as airtight container and use.

Following embodiment accompanying drawings is further described the utility model.

The specific embodiment

Referring to figs. 1 through Fig. 4, present embodiment is a kind of cylindrical shape sealable tank, comprises cover 1, tank body 2 and sealing member, and cover 1 is provided with the lid edge 4 that lid connects the top 3 of tank body, cover 1 is to being arranged with inner barrel 5, and sealing member is the flexible sealing dish 6 that is arranged on the inner barrel 5; Surround A between exhaust area by lid edge 4, inner barrel 5 and flexible sealing dish 6 threes, offering the deflation hole 7 that is communicated with A and tank body inboard between exhaust area on the barrel of inner barrel; Flexible sealing dish 6 is captiveed joint for the injection mo(u)lding disjunctor with the preferred connection mode of inner barrel 5; Like this, shaped article need not manually assemble the flexible sealing dish again on cover; Inner barrel 5 is provided with for flexible sealing dish 6 injection moulding bonded assembly preformed holes 8, in the inwall injection mo(u)lding simultaneously of inner barrel the flexible sealing dish inner covering 9 of captiveing joint with the inwall disjunctor of inner barrel is arranged; Like this, inner covering 9 and flexible sealing dish embrace jointly and disjunctor is fixed on the inner barrel, even also can not break away from after the repeatedly stressed use of flexible sealing dish; In the bottom of inner barrel 5, be provided with steady ring 10 with the inwall of tank body 2 coupling; Like this, be convenient to cover cover.

The utility model, flexible sealing dish 6 and inner covering 9 general employing silica gel moulding.

Use of the present utility model and principle of work: when cover is pressed into, flexible sealing dish 6 upwards reaches and inwardly twists, cover 1 pushes gradually, simultaneously, the gas in the tank body 2 flows to A between exhaust area along air flow line B, shifts onto last, lid edge 4 lids of cover are caught the top 3 of tank body, under extraneous difference of pressure effect, the lid edge 4 of cover and top 3 adhesives of tank body reach sealing; When opening cover, pull open the lid edge 4 of cover, outside air enters in the tank body 2 against air flow line B, under the situation of internal and external pressure balance, can open cover very effortlessly.

The utility model, the tank body shape of sealable tank can be the circles with the cover form fit, also can be ellipse, oblong, square or other polygon, certainly, are not limited to these mentioned shapes.
