Description

  The present invention relates to a spray can filling device that injects a drug and a gas (for example, air such as compressed air) into a spray can, and more particularly, to a spray can and container in which the drug is consumed. The present invention relates to a spray can filling device in which a medicine and a gas (for example, air such as compressed air) are easily divided and filled so that spray cans and containers depleted in medicine can be reused.

  In general, a spray can is a container in which a compressed gas such as gas and a medicine are compressed and filled in a liquefied state, and the gas and the medicine are injected through a nozzle. , Insecticides, fragrances, paints, pharmaceuticals, etc., are used universally throughout the industry.

  However, since most of these spray cans are manufactured and sold for disposable use, they cannot be refilled. This causes the waste of resources and environmental pollution.

  For example, in the case of spray cans used for vehicle cleaners, rust preventives, etc., about 10% of chemicals remain even in used cans. Such residual chemicals and discarded cans are a waste of resources. As well as being a major cause of environmental pollution. In addition, various problems have occurred, such as consumers being forced to pay for the cost of purchasing new products.

  In particular, spray cans used for vehicles are different from ordinary butane gas and insecticide cans, and their sales channels are limited as in vehicle maintenance shops and vehicle parts specialty stores. Therefore, if the spray can is refilled with the concept of being repeatedly used through a vehicle maintenance shop or a specialized dealer, it is possible to reduce the waste of resources and the burden on consumers.

Various proposals have been made regarding a device for filling a spray can (for example, Patent Document 1), and a medicine filled in a spray can and a gas (eg, air such as compressed air) are easily divided and filled. There was still room for improvement with regard to the spray can filling device.

  The operation and effect of the spray can filling apparatus of the present invention configured as described above will be described in detail by dividing it into a drug filling process and a gas injection process.

<Drug filling process>
In the state shown in FIG. 2, when the lever 220 is rotated and the pusher 250 is moved toward the spray can C side (left side in FIG. 2), the spray can C is pressurized, and the injection nozzle 270 is thereby moved to the spray can C. Coupled to the inlet. That is, the inlet of the spray can C is inserted in the injection nozzle 270 in a state of being in close contact, and the spray can C is kept firmly fixed (FIGS. 3 and 1).

  With the check valve V1 opened and the check valves V2 and V3 closed, the user inserts the suction pipe 600 into the medicine storage tank T as shown in FIG. When the piston 520 of the cylinder 500 moves backward due to the restoring force of the spring 530 (moves from the right side to the left side in FIG. 4), the inside of the cylinder 500 is in a vacuum state, so that the medicine in the storage tank T moves the check valve V1. Through the cylinder 500.

  At this time, the gauge 540 installed on the rod 510 side of the cylinder 500 plays a role of sensing the amount of movement of the rod 510 and displaying the injection amount of the medicine.

  Thereafter, the check valve V1 is closed, the check valve V2 is opened, the check valve V3 is closed, and the filling switch 400 is opened.

  Thereby, gas (for example, air such as compressed air) supplied from the gas pressure regulator 300 flows into the cylinder 500, and the piston 520 of the cylinder 500 is expanded by the compressed air and moves forward (in FIG. 4, Move from left to right). Thus, the medicine that has been sucked into the cylinder 500 in the above-described process is supplied into the spray can C via the check valve V2 and the injection nozzle 270.

  At this time, the closed check valves V <b> 1 and V <b> 3 serve to prevent the medicine supplied from the cylinder 500 into the spray can C from flowing back to the storage tank T and the compression pressure regulator 800.

  When the injection of the medicine from the cylinder 500 into the spray can C is completed, the filling switch 400 is closed, and the gas in the cylinder 500 (for example, air such as compressed air) is discharged to the outside. At this time, similarly to the above, the check valve V1 is opened and the check valve V2 is returned to the closed state, and the piston 520 of the cylinder 500 is moved backward by the elastic restoring force of the spring 530 (from right to left in FIG. 4). Return to the original state. As a result, similarly to the above, the medicine is again sucked into the cylinder 500 from the storage tank T.

<Gas injection process>
As described above, the check valve V3 is opened and the check valve V2 is closed in the state where the spray can C has been filled with the medicine. At this time, the check valve V1 is opened, and in parallel with the injection of gas (for example, air such as compressed air) into the spray can C to be described, the medicine from the storage tank T to the inside of the cylinder 500 described above. Can be re-inhaled.

  When the open / close switch 700 is opened, gas (for example, air such as compressed air) supplied from the gas pressure regulator 300 is injected into the spray can C via the compression pressure regulator 800, the check valve V 3 and the injection nozzle 270. The

  The pressure of the gas supplied at this time (for example, air such as compressed air) can be adjusted by the compression pressure regulator 800. In the illustrated embodiment, the pressure of the gas (eg, air such as compressed air) that fills the spray can C can be visually confirmed by a compressed air gauge 900. The check valve V2 serves to prevent gas (for example, air such as compressed air) from flowing into the cylinder 500 or the storage tank T side.

  When filling of the gas into the spray can C (for example, air such as compressed air) is completed, the open / close switch 700 is closed.

  Here, the lever 220 is rotated from the state shown in FIG. 3 to the state shown in FIG. 2, and the pusher 250 is moved from the left side to the right side in FIGS. 3 and 2, and the injection nozzle 270 and the injection port of the spray can C are moved. The spray can C which has been completely filled is removed, and the new spray can C to be focused next is set in the state shown in FIG. Then, as described above, a new spray can C is set in the state shown in FIG. 3, and the next medicine filling step is started.

  In the above-described drug filling process and gas injection process, the aforementioned opening / closing operations of the filling switch 400, the opening / closing switch 700, and the valves V1, V2, and V3 can be performed manually, or can be automatically controlled by sequence control. it can. For example, according to manual switching of the filling switch 400 and the opening / closing switch 700, the opening / closing switching of the valves V1, V2, and V3 can be automatically performed as described above. The switch 700 can be manually switched and the above-described switching of the valves V1, V2, and V3 can be automatically performed accordingly. In addition, the aforementioned opening / closing operations of the filling switch 400, the opening / closing switch 700, and the valves V1, V2, and V3 can be automatically controlled using a computer or the like.

  By switching between the medicine filling process and the gas injection process described above, the spray can filling apparatus according to the present invention allows the medicine and gas (for example, air such as compressed air) Can be easily distinguished and filled conveniently. Thus, resource loss, environmental pollution, and costs due to disposal of the spray can C can be greatly reduced.

  In particular, the spray can filling apparatus of the present invention can fill the spray can C with the necessary medicine by inserting the suction pipe 600 into various medicine storage tanks T regardless of the kind of the medicine. Further, the filling amount can be confirmed and adjusted by the gauge 540 of the cylinder 500. Therefore, it can be applied to spray cans C of various products.

  Moreover, the spray can filling apparatus of the present invention can adjust the injection amount of gas (for example, air such as compressed air) by the open / close switch 700 and is injected into the spray can C by the compression pressure regulator 800. The pressure of the gas (eg air such as compressed air) can also be adjusted. Accordingly, it is possible to fill the spray can C with a necessary amount of gas (for example, air such as compressed air) at an optimum filling pressure according to the type of product of the spray can C.

  As mentioned above, although preferred embodiment of this invention was described with reference to the accompanying drawing, this invention is not limited to this embodiment, In various forms in the technical scope grasped | ascertained from description of a claim It can be changed.
