Abstract
The utility model relates to a two-component plastic packaging sac bag used for an aerosol using compressed air as a propellent. A bag body is provided with a hermetically connected drainage tube, a tube body of the drainage tube in the bag body is provided with at least one liquid exhausting hole, and at least one liquid exhausting hole is arranged at the top of the tube body in the bag body; the inner wall of the bag body is provided with alternatively concave-convex stripes in the same direction with the drainage tube. The utility model which separates liquid medicine from the propellent is only filled with the liquid medicine, and the alternatively concave-convex stripes on the inner wall of the bag body can decrease the residual quantity of the liquid medicine to the lowest degree; the liquid exhausting holes on the drainage tube can cause the aerosol which applies the utility model to be capable of jetting regardless of the position to bring convenience to use. The utility model which can be repeatedly filled to reduce the use cost of the aerosol can be applied on a medicinal aerosol if a medical grade polyvinyl chloride material is adopted.
Description
Technical field
The utility model relates to a kind of binary plastic wrapping capsule bag that is applicable to aerosol.
Background technology
Aerosol enters into our life more and more, contains propellant in the aerosol, and the soup in the aerosol sprays with vaporific or spumescence by valve under the propellant effect.China Patent No. is the binary plastic packets tinning that 00232653.1 utility model patent specification sheets discloses a kind of aerosol, be provided with plastic bag in its metal can, adopt plastic bag to fill soup and propellant, soup is not directly contacted with tank body, solved the corrosion-prone problem of tank body.But the aerosol of above-mentioned employing binary plastic packets tinning is the same with at present all aerosols, propellant and soup are in the same container, propellant also entered in the surrounding air when soup penetrated, and propellant generally all has some bad influences to environment, the hygienic conditions that this and modern pursue are inconsistent, existing at present research is with the aerosol of pressurized air as propellant, and the soup of this kind aerosol is placed separately, and propellant is in the outside of soup.
The utility model content
The purpose of this utility model be propose a kind of be used for aerosol with pressurized air as propellant binary plastic wrapping capsule bag.
For achieving the above object, the drainage tube that the utility model is taked bag to be provided with to be tightly connected, be provided with at least one outage on the body of drainage tube in bag, and have at least a hole to be arranged on the top of the body in the bag in the outage, have on the inwall of bag and drainage tube concavo-convex alternate striped in the same way.
Be provided with the single valve fore shaft that is tightly connected on the body of above-mentioned drainage tube outside bag, the single valve fore shaft has the stepped central hole.
The underpunch in above-mentioned single valve fore shaft stepped central hole is a taper hole.
The ladder plane in above-mentioned single valve fore shaft stepped central hole is inside and downward-sloping.
The bottom of above-mentioned bag is the arc to fovea superior.
Above-mentioned bag, drainage tube and single valve fore shaft all adopt the polyvinyl chloride material to make.
Soup in the utility model penetrates by aerosol valve under the pressurized air effect, and the outage on the drainage tube can make application aerosol of the present utility model can both spray under inversion state, brings convenience to use; The concavo-convex alternate striped on the bag inwall and the setting of the outage on the above-mentioned drainage tube can make the residual volume of soup be reduced to a minimum; The utility model separates soup and propellant, has both solved the corrosion-prone problem of external metallization jar, and can repeatedly, falls the use cost of end aerosol; The utility model then can be applied on the medicinal aerosol formulations as taking medical grade polyvinyl chloride material.

The specific embodiment
Embodiment 1
Embodiment illustrated in fig. 11 comprises bag 1, and for adapting to the shape of spray metal can bottom, the bottom 1-1 of bag 1 is the arc to fovea superior.Bag 1 is provided with the drainage tube 2 that is tightly connected, bag 1 and drainage tube 2 be connected injection moulding bag 1 time finish.Be provided with at least one outage 3 on the body 2-1 of drainage tube 2 in bag 1, decide with the thickness of body 2-1 in the aperture of outage 3, is typically chosen between 1.5～2.6mm.In outage 3, have at least a hole to be arranged on the top of the body 2-1 in the bag 1, present embodiment takes the top of the body 2-1 of drainage tube 2 in bag 1 to be provided with two relative outages 3 that communicate with the body chamber, when the spray metal can is in inverted state, soup can enter drainage tube 2 by the top outage 3 of body 2-1, provides convenience for the use of using aerosol of the present utility model.The inwall of bag 1 have with drainage tube 2 in the same way and the concavo-convex alternate striped 1-2 of well-distributed, accompanying drawing has only been done signal in the part.The size of the thickness of striped and bag 1 matches, and bag is big, and striped can slightly be typically chosen between 0.1～3.0mm.The bag inwall is provided with on striped 1-2 and the body 2-1 in bag 1 and is provided with outage, can play the effect of control soup residual volume, and discharging is clean as far as possible to make soup.Above-mentioned bag 1 and drainage tube 2 all adopt the polyvinyl chloride material to make.Be connected by aglet between the aerosol valve body of present embodiment and spray.Embodiment 2
See Fig. 2 to Fig. 4, on the basis of embodiment 1, be provided with the single valve fore shaft 4 that is tightly connected on the body 2-2 of drainage tube 2 outside bag 1, the setting of single valve fore shaft 4 is convenient to be connected with the aerosol valve body of spray.Single valve fore shaft 4 has stepped central hole 5, and the underpunch 5-1 in single valve fore shaft 4 stepped central holes 5 is a taper hole, is convenient to the insertion of drainage tube 2.Because spray valve body and single valve fore shaft are made by plastics, omit tool elasticity, so the conical head 6 of the valve body of spray check valve can insert among the underpunch 5-1 in the stepped central hole 5 in the single valve fore shaft 4, the suitable hangnail of the step portion of centre hole 5, deformation can take place in the ladder plane 5-2 that considers the stepped central hole 5 of single valve fore shaft 4 after stressed, so the ladder plane 5-2 in the stepped central hole 5 of single valve fore shaft 4 is inside and downward-sloping, inclined angle alpha is between 22～25 °, when being subjected to application force, the 5-2 extrusion of ladder plane becomes the plane, 4 of the valve body of spray check valve and single valve fore shafts are difficult for slippage, and 4 of the valve body of check valve and single valve fore shafts are aided with lining cement in case of necessity.Single valve fore shaft 4 adopts the polyvinyl chloride material to make.
Basic identical with embodiment 1, difference is seen Fig. 4, is provided with 4 outages 3 on the body 2-1 of drainage tube 2 in bag 1, and wherein two holes are at the top of body 2-1, and two holes are in the middle and upper part of body 2-1.
