Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an aerosol container connection device that injects liquid or powder contained in a closed container using a pressurized medium sealed in a pressure cylinder.

In conventional aerosol containers, the aerosol container and the pressurized cylinder storage container are connected to each other through a flexible hose, and the aerosol container and the pressurized cylinder storage container are integrally connected by a connector. . This product connects the aerosol container and the pressurized cylinder storage container with a hose, so it ensures the fastening and sealing between the hose and the pressurized cylinder storage container, and also has a cap to which the hose is attached to the aerosol container. This also requires fastening and sealing between the cap and the seal. As a result, the number of places to fasten and seal increases, making fastening and leakage prevention a hassle.
It was also complicated to handle.

The present invention is a device that eliminates the above-mentioned drawbacks and is constructed as follows. That is, a cap for opening the pressure cylinder and a puncture tool for opening the sealed container are provided in a pedestal in communication with each other, and a second pressing tool for pressing the pressure cylinder toward the cap and a puncture tool for the sealed container are provided in communication with each other. This is an aerosol container connection device in which a pedestal is provided with a first pressing tool for pressing toward the container.

This invention will be described in detail below based on illustrated embodiments.

FIG. 1 is a cross-sectional view of a main part showing the state in which the connecting device according to this invention is used.
It has pressing tools 4 and 5 that press and hold the closed container B and the pressure cylinder C, respectively.

The pedestal 1 has a decorative plate 7 on the outer periphery of the casing 6.
Inside the casing 6, a horizontally formed cylinder chamber 8 and a storage chamber 9 for the pressure cylinder C are arranged vertically. The cylinder chamber 8 and the storage chamber 9 communicate with each other at their inner ends through a communication passage 10, and at the inner end of the cylinder chamber 8 there is a valve body 11 fixed to the casing 6 and a flow path of the valve body 11. on its upstream side (left side in the diagram)
A needle valve 12 that opens and closes from the housing chamber 9 is provided, and a base 2 that projects toward the housing chamber 9 is provided on the inner end side of the housing chamber 9. The protruding portion of the base 2 is sharpened into a conical shape.

The needle valve 12 is connected via a connecting rod 13 to a piston valve 14 fitted into the cylinder chamber 8, and is normally biased open by a valve spring 15 via the piston valve 14. Note that 16 is a spring holder, 16
a is a breathing port.

Further, the inner side of the cylinder chamber 8 is communicated with the outside from the center of the casing 6 via a discharge passage 17, and the piercing tool 3 is attached to the upper end of the discharge passage 17. This puncture tool 3 has a mounting surface 1 which forms the upper surface of the casing 6 by having an opening portion 3a that is pointed in a conical shape.

As shown in FIG. 6, this puncture tool 3 has a seal portion 3b surrounding the base of the opening portion 3a, and a pressurizing channel 17a is opened on the side of the opening portion 3a from the seal portion 3b.

Note that the discharge passage 17 is initially closed by the piston valve 14 when the piston valve 14 is moved leftward by the valve spring 15. A cap-shaped second pressing tool 5 is screwed onto the open end side of the storage chamber 9. This pressing tool 5 presses the pressure cylinder C accommodated in the storage chamber 9 inward, that is, in the direction of the cap 2, and uses the protrusion of the cap 2 to press the pressure cylinder C.
It pierces through the head of the person.

In addition, a female thread cylinder 1 is provided on the outer periphery of the upper surface of the casing 6.
9 is formed, and the cylindrical first pressing tool 4 is screwed into this internally threaded cylinder 19. The first pressing tool 4 surrounds the closed container B with its body, and engages with the upper periphery of the closed container B by means of a flange 4a formed on its upper edge in the inner radial direction, thereby pushing the closed container B downward, i.e. The opening part 3a of the puncture tool 3 pierces the bottom wall of the closed container B by pressing in the direction of the puncture tool 3.

The airtight container B and pressure cylinder C are made of sheet metal or synthetic resin, and the airtight container B is filled with liquid, powder, etc., and the head is equipped with a push cylinder. type on-off valve 2
0 is provided, and the supply path of the on-off valve 20 is connected to the outflow pipe 2.
1 to the bottom of the closed container B. Further, the pressure cylinder C is filled with a pressure medium such as carbon dioxide gas.

Here, the first pressing tool 4 that presses and holds the airtight container B described above may have a structure shown in FIGS. 2 and 3.

That is, the spring wire 4a is bent into an inverted U-shape as shown in FIG.
is bent into an inverted L shape as shown in Fig. 2, and its tip is reversely bent into a downward arc shape.
This inverted bent portion 4d is elastically secured to the upper surface of the closed container B.

Next, FIGS. 4 and 5 show still another embodiment, in which a casing 6 constituting a pedestal 1 is arranged horizontally in an elongated rectangular bar shape, and a cylinder chamber 8 is placed in the front part of the casing 6 and a storage chamber is placed in the rear part of the casing 6. 9, the upper surface of the first half of the pedestal 1 is used as the mounting surface 18 for the airtight container B, and the first pressing tool 4, which also serves as an inverted L-shaped handle, is provided on the upper surface of the rear half so that it can be inserted and removed. is significantly different from that of the embodiment described above.

The first pressing tool 4 is an L-shaped hollow body, and as shown in FIG. 5, the lower part thereof can be inserted into and removed from the dovetail-shaped engagement groove 22 formed in the casing 6 from the rear to the front. The upper part of the handle 23 is bent forward so that the lower surface of the lower end is formed as the holding surface 24 of the closed container B, and the operating lever 25 of the on-off valve 20 is attached to the upper part. It becomes attached.

The front part of the holding surface 24 is continuously formed with an elongated hole 26 into which the constricted portion of the base of the on-off valve 20 is fitted, and a circular window hole 27 into which the head of the on-off valve 20 is fitted. When the first pressing tool 4 is attached, the on-off valve 20 is accommodated in the front hollow part of the first pressing tool 4. In the figure, 28 is a spring that presses the operating lever 25 clockwise.

Further, other embodiments of the piercing tool are shown in the seventh, eighth, and third embodiments.
It is described in Figures 9 and 10. The puncture tool 3 shown in FIGS. 7 and 8 has the tip of the opening part 3a formed obliquely, and the one shown in FIGS. 9 and 10 has a groove 17b provided on the outer periphery of the puncture tool 3. It also serves as a pressurizing flow path.

Next, the effect of this invention will be explained.

First, in the embodiment shown in FIG. 1, the first pressing tool 4 is removed from the pedestal 1, and the closed container B is housed in the first pressing tool 4. In this state, if the first pressing tool 4 is loosely screwed into the female threaded cylinder 19 of the pedestal 1, and then the sealed container B is manually pushed down, the bottom wall of the container B will be pierced by the piercing tool 3. It will be broken. Next, when the first pressing tool 4 is firmly screwed into the female threaded cylinder 19, its flange 4a will press and hold the upper surface of the closed container B toward the mounting surface 18 side.

In this case, the inside of the closed container B communicates with the discharge passage 17 via the piercing tool 3, but since the discharge passage 17 is closed by the piston valve 14, the inside of the closed container B
The filling material inside will not leak into the cylinder chamber 8.

Next, after removing the second pressing tool 5 from the pedestal 1 and inserting the pressure cylinder C into the storage chamber 9, the second pressing tool 5 is firmly screwed onto the pedestal 1 again. (left end in the figure) is pierced by the cap 2.

As a result, the pressure medium in the pressure cylinder C flows into the cylinder chamber 8 via the mouthpiece 2 and the communication passage 10,
The piston valve 14 is moved to the right against the elastic force of the valve spring 15 to open the discharge passage 17.
flows into the closed container B via the puncture tool 3,
The pressure inside the container B is increased to a predetermined pressure.

In this case, the needle valve 12 is connected to the piston valve 14 via the connecting rod 13, and as the piston valve 14 is moved rightward by the pressure medium from the pressure cylinder C, the communication passage 10 is gradually closed by the needle valve 12, and as a result, the airtight container B is closed by the pressure cylinder C.
The pressure rise within the device is automatically maintained at the set pressure.

In the above state, when the on-off valve 20 is pressed to open it, the filling in the closed container B is ejected from the bottom of the container B to the outside through the outflow pipe 21.

On the other hand, since the closed container B is mounted and connected to the pedestal 1 in which the cap 2, the pressure cylinder C, and the communication passage 10 are centrally arranged, the container B is made smaller and more stable as a whole.

Next, in the embodiment shown in FIGS. 2 and 3, since the first pressing tool 4 is composed of a spring wire rotatably attached to the pedestal 1, the closed container B can be quickly attached and detached. It can be done easily and is inexpensive. Furthermore, in the embodiment shown in FIGS. 4 and 5, the body of the first pressing tool 4 is a handle 23, and the operating lever 25 is attached, so that it is easy to carry and can be stored inside the closed container B. The filling material can be spouted easily.

Since the present invention has such a configuration, the number of fastening and sealing parts is reduced, fastening and leakage prevention are simple, and handling is also extremely easy. In addition, conventional aerosol containers had a pressurized medium sealed inside the container, which was dangerous unless the container was pierced and disposed of after use. Because it can be used in a vacuum, there is no need to go to the trouble of drilling holes after use, and it is safe to throw away.
