Technical solution of the present utility model is:

A kind of general lid of inflating, comprise shooting valve, shooting valve comprises valve body, spool, injector head is housed on the shooting valve, and the difference of itself and prior art is: shooting valve is fixed on the top of prominent wall in the lid, adorns seal ring between the inner face at prominent wall top and the shooting valve in lid, the inner face of lid periphery wall with inflate a glass rim of a cup sliding sealing and be connected, inflate and have vent on the wall of cup, prominent wall top has induction opening in the lid, also has aperture on the valve body of shooting valve.Lid comprise periphery wall and from periphery wall bottom to the interior prominent wall of inner process.

Inflate glass rim of a cup tool to outer process, be piston ring-type or other suitable forms.Shooting valve is fixed on that the valve pocket on the prominent wall in the lid is pushed down and the top that is contained in the wall of dashing forward lid in.Shooting valve also can adopt other suitable forms to be contained in the top (for example: fix with glue or other connecting element) of prominent wall in the lid.Lid is made with metal or plastics, rubber, glass or other suitable materials.Also be equipped with in the lid bottom and cover joint.The lid joint can be made corresponding form, size, specification according to form, size, the specification of the vessel port of installing.Certainly,, also can not add a cover joint, and directly be spirally connected or socket or be connected on the vessel port with other suitable methods if when the form of lid lower openings, size, specification and vessel port match.

The utility model is because what adopt is that lid is inflated injection system, do not need annotate in advance air pressure and propellant in the container, when being used by the user, air pressure throws at any time, so the product of this system does not need the container and the bigger product lot quantity of special-purpose inflation filling apparatus and unified standard, just can produce on common can packing machine, this has alleviated the cost of investment of manufacturer greatly.And owing to do not use propellant, therefore stopped when propellants such as fluorine Lyons use discharging pollution to atmosphere.Simultaneously because customer itself just can repeat can use, this not only improved container degree of utilization, saved expense but also reduced waste, thereby protected environment.Because the pressure in the container, what can regulate by inflating number of times, therefore, can spray various pulvis, liquid, grease, emulsion and colloid, be applicable to that medicine, chemical industry, daily necessities and industrial or agricultural every field need have on the various containers of constant air pressure injection.In addition, when lid is connected with vessel port, can be according to form, size, the specification of vessel port, select the lid joint of multi-form, size, specification for use, make and inflate lid and can conveniently be contained on the vessel port of any form, size, specification.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the configuration diagram of an embodiment of the utility model.

Shooting valve comprises valve body 4 and spool 7 among the figure, have an aperture 8 that communicates with endoporus in the middle of it on spool 7 walls, injector head 6 is housed on the shooting valve, lid comprises periphery wall 2 and from the interior prominent wall 13 of periphery wall to inner process, and shooting valve is fixed on the valve pocket 10 on the prominent wall 13 in the lid and pushes down and be contained in top on the wall 13 of dashing forward lid in.Between the inner face at prominent wall 13 tops and the shooting valve ring gasket sheet seal ring 5 is housed in lid, the inner ring of seal ring 5 is enclosed on the spool 7, and outer ring and upper surface are close to lid and pay on the inner face of interior prominent wall.Lid periphery wall 2 inner face with inflate the cup 3 rim of a cup sliding sealings be connected, inflate cup 3 rim of a cup tools to outer process, be the piston ring-type, certainly cup 3 rims of a cup of inflating also can adopt other suitable forms, inflate and have vent 11 on cup 3 the wall, prominent wall 13 tops have induction opening 9 in the lid, have aperture 12 on the valve body 4 of shooting valve.The lid and the cup 3 of inflating can be made with metal or plastics, rubber, glass or other suitable materials, also be equipped with and vessel port form, the corresponding lid of size joint 1 in the lid bottom, certainly, if the form of lid lower openings, size when corresponding with vessel port, also can not added a cover joint 1.Can be between lid and the lid joint 1, between lid joint 1 and the spray containers or between lid and the spray containers with being spirally connected or socket or other suitable forms are connected.
