Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing.

As shown in Figure 1, a kind of aerosol container with plastic inner container, including aluminium pot 1 and aerosol valve 2, the aluminium Tank 1 includes tank body 11 and tank mouth 12, and the aerosol valve 2 includes the spool 21 set gradually from top to bottom, is tightly connected Pipe 22 and the feeding pipe 23 being connected to sealed joint pipe 22, the spool 21 is tightly connected with tank mouth 12, in the tank body 11 It is provided with plastic inner container 3, the plastic inner container 3 includes the gallbladder body 31 being in close contact with 11 inner wall of tank body and inserts for feeding pipe 23 The inner-tube mouth 32 entered, the inner-tube mouth 32 are closely connect with the outer wall of sealed joint pipe 22, the inner-tube mouth 32 and gallbladder body 31 it Between be additionally provided with compressed elastic construction 33.

A kind of aerosol container with plastic inner container 3 of this programme, specific installation step is: 1, filling in plastic inner container 3 Enter in tank body 11, referring to attached drawing 4 and attached drawing 5, because 111 tank mouth of aluminium pot, 12 diameter is less than plastic inner container 3, so needing will be in plastics Gallbladder 3 is suitably rolled and is filled in, and plastic inner container 3 has flexibility, and the plastics kind and specific material this programme specifically used does not limit It is fixed；2, it is inflated using compressed air or compressed nitrogen into the gallbladder body 31 of plastic inner container 3, carrys out its spread apart in tank body 11； 3, content Material such as cream rinse Material is packed into liner；4, it is packed into aerosol valve 2, feeding bar is inserted into liner first Mouth 32, until the outer wall of inner-tube mouth 32 and sealed joint pipe 22 is in close contact, to reach sealing function；5, using grabbing mouthful machine for gas The spool 21 and tank mouth 12 of mist agent valve 2 sufficiently promptly, have the function that entire product sealing；6, propellant, such as the third fourth are filled Alkane.Compared with prior art, it is that aerosol valve 2 is prepared respectively with plastic inner container 3 the advantages of this programme, avoids welding and make Industry reduces loss, to reduce cost；It is irrigated by inner-tube mouth 32, charging efficiency is high, improves production efficiency；It is close Seal structure deft design is reasonable, improves the leakproofness of plastic inner container 3 Yu aerosol valve 2, by elastic construction 33 and promotes Agent is applied to the dual-pressure of inner-tube mouth 32, ensure that the sealing of inner-tube mouth 32 and the i.e. aerosol valve 2 of sealed joint pipe 22 is imitated Fruit.

For sealing structure, specifically, 3 size of plastic inner container is higher under natural conditions referring to attached drawing 4, it is put into tank body 11 In after can protrude from tank mouth 12, in insertion aerosol valve 2 and after sealing, elastic construction 33 be in confined state, can be internally Gallbladder mouth 32 generates upward elastic force；Meanwhile after filling propellant, plastic inner container 3 will receive the outside pressure of propellant.Then, bullet Property structure 33 under the double action of own resilient and propellant air pressure, generate upward power, promote plastic inner container 3 and spool 21 Combine closely, even if inner-tube mouth 32 holds out against the spool 21 of valve；Meanwhile the sealed joint pipe 22 of inner-tube mouth 32 and spool 21 Outer wall generates sealing function by contact surface.

Further, the shape of the elastic construction 33 is corrugated or C-shape.Referring to attached drawing 2 to attached drawing 5, elasticity Structure 33 can be corrugated, that is, is similar to spring structure, can generate preferable elastic force.It is also possible to C-shape, structure It is pressed from both sides similar to metal clips.Actually this programme concrete shape for not limiting elastic construction 33, as long as in capable of having and being applied to 32 elastic force of gallbladder mouth guarantees the shape of the leakproofness of plastic inner container 3 and aerosol valve 2.

Further, the gallbladder body 31, inner-tube mouth 32 and elastic construction 33 are integrally formed setting.The mesh being arranged in this way Be that can reduce the cost of manufacture of plastic inner container 3 and ensure that the whole structural strength of plastic inner container 3.

Further, the card slot 13 docked with spool 21 is provided at the tank mouth 12.The setting of card slot 13 is for side Just spool 21 docks, and is sealed using a mouthful machine is grabbed, ensure that the connection effect of aerosol valve 2 Yu aluminium pot 111.

The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
