DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol product degassing tool and an aerosol product provided with the degassing tool.

[0002]

2. Description of the Related Art In an aerosol product, even if the injection member such as a push button or a spout is operated and the contents do not come out, some gas remains inside unless a hole is made in the container to communicate with the atmosphere. . In particular, in the case of products using liquefied gas, when the content is reduced, the internal pressure is temporarily reduced by injection, and it may become more difficult to come out more. Therefore, it is easy for a user to misunderstand that the product has been used up. If the contents are discarded while being left, accidents such as rupture or explosion may occur during incineration. In order to prevent such accidents, consumers have conventionally been encouraged to depress the push button and completely degas the gas before disposing of the aerosol product. In order to further reduce the labor for keeping the push button pressed, a venting tool has been proposed that can maintain the valve in an open state when fitted to a container. As such a degassing tool, for example, Japanese Unexamined Patent Publication No.
There is one disclosed in Japanese Patent Application Laid-Open No. 337278/337.

As shown in FIG. 7, this degassing tool engages with a cap 102 for valve protection which can be fitted on the outer periphery of a mounting cup 101 and an inner surface of the mounting cup protruding from a side surface of the cap. A pair of positioning projections (legs) 103 are provided, and a valve opening projection 104 protruding from the side surface between them is provided. Such a degassing tool 105 can be used as a cap before the aerosol product is used, for example, in a distribution channel, etc. After use, the portion of the cap 102 is gripped and the positioning projection 103 is attached to the mounting cup 101. Gas can be vented by engaging with the inner surface of.

[0004]

The degassing tool 105 can be used as a part for gripping the cap 102, but the cap 10 is degassed in a degassing state.
2 protrudes greatly from the container body 106. Therefore, normally, the degassing tool 105 is discarded after being removed from the container body 6. Even when not removed, the engagement between the two positioning projections 103 is unstable, and the positioning projections 103 may come off from the container body 106 at the time of disposal or the like.
Therefore, when the user disposes or when the waste collection company collects the gas, whether the gas has been vented or the gas remains is indistinguishable from the appearance alone. Therefore, immediately before disposal, at the time of collection or incineration, it is necessary to shake the container or open the valve to confirm again whether there is residual gas.

It is an object of the present invention to provide a degassing tool which allows the presence or absence of degassing to be immediately recognized from the external appearance, so that it is not necessary to confirm again immediately before disposal or immediately before incineration. A further object of the present invention is to provide a degassing tool that can be stably attached to a container body and is difficult to fall off.

[0006]

An aerosol product degassing tool according to the present invention has a cylindrical outer peripheral wall and an intermediate wall extending inside the outer peripheral wall, and is turned upside down on the outer peripheral wall. An engagement portion that engages with the mounting cup is provided,
A push rod for opening the valve in a state where the engaging portion is engaged with the mounting cup is protrudingly provided at the center of the upper surface of the intermediate wall.

In such a degassing device, the lower portion of the outer peripheral wall is housed and held in the annular concave portion of the mounting cup, and the engaging portion is formed on the outer periphery of the upper portion of the outer peripheral wall.
It is preferable that the engagement projection is provided at a position where the projection is engaged with the inner wall of the annular concave portion of the mounting cup in the inverted state.

A bottomed cylindrical body comprising a lower part of the outer peripheral wall and an intermediate wall constitutes a mounting cup or a cap for protecting the injection member. The engaging portion and the push rod are provided on the upper surface side, and the outer periphery is provided. A second engaging portion that engages with the mounting cup may be provided on the inner peripheral surface near the lower end of the wall.

Further, the push rod extends downward beyond the intermediate wall so as to perform the function of a stem for opening and closing the valve.
A degassing tool having a communication hole extending in the axial direction is preferable.

[0010] A second aspect of the degassing device of the present invention is a support portion having a form accommodated and held in an annular concave portion of the mounting cup, and a mounting cup provided in an inverted state provided on an upper outer periphery of the support portion. And a push rod for opening a valve provided at the center of the upper part of the support part.

A third aspect of the degassing tool according to the present invention has a cylindrical outer peripheral wall and an intermediate wall extending inside the outer peripheral wall, and an engaging portion that engages with the mounting cup on the outer peripheral wall. Is provided, and a push rod for opening the valve is protrudingly provided at the center of the intermediate wall.

[0012] In any of the above-mentioned degassing tools, it is more preferable to provide a display indicating that the gas has been vented in a portion which can be viewed from the outside in a state where the engaging portion is engaged with the mounting cup.

An aerosol product provided with a degassing tool according to the present invention comprises: a container body containing contents; an aerosol product including a mounting cup for mounting a valve crimped from the inside at an upper opening of the container body; It comprises any one of the degassing tools attached to the mounting cup of the product, wherein the container body of the aerosol product and the degassing tool are made of substantially the same material.

[0014]

The degassing device of the present invention is mounted on the mounting cup at the time of distribution or when the aerosol product is not used. In this case, the engaging portion is not engaged with the mounting cup, and the push rod is also directed upward, so that the function of opening the valve is not achieved. Then, when the aerosol product has been used, it is turned upside down, and the engaging portion is engaged with the mounting cup. The push rod then pushes the valve open, opening the valve and allowing gas to escape. After that, keep the degassing equipment without removing it and discard it as it is at the time of waste collection or hand it over to a recycler. In this case, since the inside of the container and the atmosphere are in communication, the residual gas in the container is completely discharged. Moreover, since the degassing tool is mounted upside down on the mounting cup, it is immediately apparent from the appearance that the gas has been degassed. Therefore, it is not necessary to confirm that the contents are empty by shaking the container each time.

Further, in the degassing device of the present invention, since the engagement portion is provided on the cylindrical outer peripheral wall, the engagement with the mounting cup is stable, and there is little possibility of falling off at the time of disposal. The engaging part only needs to be engaged with the mounting cup with the degassing tool turned upside down, and the push rod is also provided at the upper part of the intermediate wall, so unless the function of the aerosol product is impaired, The lower surface of the wall can be used for other purposes.

According to the second aspect of the present invention, in the distribution step, the lower part of the outer peripheral wall of the aerosol product in a state where the injection member such as the push button, the spout and the stem is removed is accommodated in the annular concave portion of the mounting cup. Package in the form in which it is held. Thereby, the upper opening of the valve can be protected. In this case, since the degassing device can be packaged so as not to protrude much from the mounting cup, the packaging form can be made smaller than when the degassing device is packaged separately from the container body. Note that the spray member is reused after being removed from the aerosol product previously used by the user. However, optional items can be used.

The degassing device is removed from the mounting cup when using the aerosol product.
The spray member is attached to the valve of the aerosol product for use. After the use of the aerosol product, the ejection member is removed, the degassing tool is turned over and engaged with the mounting cup to perform degassing.

In the gas venting device of the third aspect, the lower portion has a form of a cap, and the second engaging portion is provided near the lower end, so that it can be used at the distribution stage or when the aerosol product is not used. It can be used as a cap for protecting the ejection member. When the aerosol product has been used, degassing can be performed by removing the injection member and turning it upside down to engage the mounting cup as described above.

In the gas venting device of the fourth aspect, the push rod and the extension extending beyond the intermediate wall can be used as the stem. Therefore, there is no need to remove the degassing tool at the start of use. After using aerosol products,
The ejection member is removed from the push rod, turned upside down and engaged with the mounting cup as described above, and degassing is performed.

According to a second aspect of the degassing tool of the present invention, the support portion is housed and held in the annular concave portion of the mounting cup during the distribution stage or the like. In that state, the valve can be protected. At the time of use, the degassing tool is stored separately from the aerosol product, and the valve is used by attaching a jetting member such as a push button or a spout. When the contents have been used, remove the spraying member and attach the stored degassing tool to the mounting cup in an inverted state. This causes the push rod to open the valve and the residual gas escapes from the container body. In that case,
Since the degassing tool can be attached to the mounting cup without protruding so much, it can be discarded as it is at the time of disposal, that is, with the degassing tool attached to the mounting cup. Therefore, it is immediately apparent from the appearance whether or not degassing has been completed.

In a third aspect of the degassing device of the present invention, the gas is packaged together with or integral with the aerosol product at the distribution stage. When the aerosol product is used, it is stored separately from the aerosol product. After the aerosol product has been used, the ejection member is removed, a degassing tool is attached, and the product is discarded as it is. It is easy to see from this appearance whether or not the gas has been vented.

In any of the above-mentioned degassing tools, if a degassing indication is provided in a portion which can be seen from the outside when engaged with the mounting cup, it is not known that the degassing tool is used. For example, the information that the gas has been degassed can be reliably transmitted to a collection company or a waste disposal company.

In the aerosol product provided with the degassing device according to the present invention, the degassing device is removed from the container body even when the container is separated and discarded because the container body and the degassing device are made of substantially the same material. No need, easy to recycle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a degassing tool and an aerosol product according to the present invention will be described with reference to the drawings. 1a and 1b are partially cutaway perspective views from above and below of an embodiment of the degassing device of the present invention, respectively, and FIGS. 2a and 2b are sales of an aerosol product to which the degassing device is mounted, respectively. FIG. 3 is a cross-sectional view showing the state of use of the aerosol product when the aerosol product is used, and FIG. 4 is a side view showing another embodiment of the injection member according to the present invention; FIG. 5b is a cross-sectional view of a main part showing the state of the aerosol product according to another embodiment of the present invention at the time of sale and at the time of degassing, and FIGS. 6a and 6b are respectively the state of the aerosol product at the time of sale and at the time of degassing. It is principal part sectional drawing which shows a state.

Degassing tool A shown in FIGS. 1a and 1b
Is provided with a cylindrical outer peripheral wall 1, a disk-shaped intermediate wall 2, which is passed in the middle of the outer peripheral wall so as to partition up and down, and a push rod 3 protruding upward at the center of the intermediate wall 2. . The push rod 3 has basically the same shape and dimensions as the stem of the valve of the aerosol product to be used. On the surface of the outer peripheral wall 1, there is provided an annular projection 4 which engages with the mounting cup in an inverted state. The annular projection 4 may be continuous or partially interrupted. Further, it may be a continuous step portion or a partial protrusion or step portion which is radially arranged in plural. The intermediate wall 2 is formed with a through-hole 5 communicating the upper and lower spaces.

As shown in FIG. 1B, on the bottom surface of the intermediate wall 2, there is provided a display 6 indicating that "degassing has been completed". The degassing tool A can be integrally formed of a synthetic resin or metal, but is preferably made of the same material as the mounting cup or container body of the aerosol product to be used.

Degassing tool A constructed as described above
Is sold attached to the aerosol product 10 as shown in FIG. 2a. The aerosol product 10 comprises a container body 11 and a mounting cup 12 crimped on an upper opening thereof.
And the valve 13 held by the mounting cup
And a content 14 filled in the container body 11. The push button 15 and the stem 16 to be attached to the valve 13 are separately prepared or use the parts of the aerosol product used before. The valve 13 employed here is a conventionally known diaphragm type valve,
The stem 16 of the push button 15 can be easily attached and detached. However, if the stem is detachable, it need not be a diaphragm type.

As shown in FIG. 3, the valve 13 has a housing 17 and a valve body 18 which is put on the upper end of the housing.
The central portion of the mounting cup 12 is bent downward so that the peripheral portion 18a of the valve body 18 is
And a central portion thereof is bent downward to form a cylindrical seal portion 19. The lower end of the seal portion 19 comes into contact with the periphery of the central enlarged portion 18b of the valve element 18 to perform a sealing action. The periphery of the mounting cup 12 is a flange portion 21 having an inverted U-shaped cross section and covered by the bead portion 20 of the container body 11. A seal member 22 is interposed between the flange portion 21 and the bead portion 20.

As can be seen from FIG. 2a, degassing tool A
The outer diameter of the outer peripheral wall 1 is a dimension fitted and held on the inner peripheral surface of the flange portion 21 of the mounting cup 12. The annular projection 4 does not interfere with the mounting cup 12 and the valve 13 in the upright state, and engages with the inner surface inclined portion 12a of the mounting cup 12 when the push rod 3 is fitted to the valve 13 by turning over. Position (see FIG. 2b). Also when the degassing tool A is attached to the mounting cup 2 in an upright state, the intermediate wall 2 does not interfere with the valve 13 when the lower end of the outer peripheral wall 1 is in contact with the bottom surface 12b of the annular concave portion of the mounting cup. I'm doing it. Therefore, when the degassing tool A is attached to the mounting cup 12 as shown in FIG. 2A, the gas releasing tool A comes into firm contact with the bottom surface 12b of the annular concave portion and is stabilized.

The push button 15 and the stem 16 are used by being attached to the valve 13. The user can purchase the push button 15 or the stem 16 separately or use the push button 15 which has been used before.
And save the stem 16 without throwing it away and use it. It should be noted that a spout 24 shown in FIG. Reference numeral 25 in FIG. 4 denotes a shoulder cover that engages with the flange portion of the mounting cup, is continuous with the spout 24 via a hinge, and is formed integrally with the spout. Reference numeral 26 denotes an overcap to cover the shoulder cover 25.

The degassing tool A attached to the mounting cup 12 at the time of sale can protect the valve 13 at the distribution stage or during storage by the consumer. At the start of use, the user removes the degassing tool A from the mounting cup 12, and as shown in FIG.
5 and stem 16 are attached to valve 13. The removed degassing tool A is stored separately. The aerosol product 10 shown in FIG. 3 is similar to a conventional aerosol product,
When the push button 15 is depressed, the valve element 18 is depressed, the sealing action between the cylindrical seal portion 19 at the center of the mounting cup 12 is released, and the contents inside the container are passed through the hole 18 c formed in the valve element 18. Is injected.
When the push button 15 is released, the valve is closed again by the sealing action.

After using the aerosol product 10,
As shown in FIG. 2 b, the push button and the stem are removed from the valve 13, and the degassing device A is engaged with the inclined surface 12 a of the mounting cup 12 in an inverted state.
As a result, the tip of the push rod 3 becomes the mounting cup 12
And presses the valve body 18 downward. In this case, the annular projection 4 is substantially entirely engaged with the inner inclined surface 12a below the flange portion 21, so that the reaction force of the valve 13 can be stably supported. When the push rod 3 is continuously pressed, the valve 13 is opened,
The remaining contents, especially gas, are injected through the through holes 5. Although the gas leaks from the annular projection 4 or the gap between the outer peripheral wall 1 and the mounting cup 12 without providing the through hole 5, it is preferable to provide the through hole 5 because the gas removal time is short. The push button and stem removed from the valve 13 are kept by the consumer for the next aerosol product.

The degassing tool A once attached to the mounting cup 12 is discarded together with the aerosol product 10 without being removed. Since the degassing tool A which has been turned upside down is provided with a sign indicating “degassing” (reference numeral 6 in FIG. 1 b) on the bottom side of the intermediate wall, it is immediately recognized that degassing is performed. Therefore, there is no need to confirm again whether or not the contents remain when the consumer hands over to a waste collection company. Also, the waste disposal company does not need to check again immediately before incineration. It is clear that the degassing has already been performed by mounting the degassing tool A in an inverted state, but it is preferable to provide the display 6 also for a trader who does not know this.

When the degassing tool A is made of the same material as the container body 11 and the mounting cup 12, it is not necessary to separate the degassing tool A when separating and collecting the aerosol product 10. That is, when the container body 11 and the mounting cup 12 are made of metal such as aluminum or tinplate, the degassing tool A is also made of the same metal. Also, the container body 11 and the mounting cup 12
Is molded from a synthetic resin.

The above-described push button 15 and stem 16, and the spout 24, shoulder cover 25 and overcap 26 shown in FIG. 4 are usually made of synthetic resin. Becomes lower.

In the degassing device A, the outer peripheral surface of the outer peripheral wall 1 is engaged with the inner surface of the flange portion 21 of the mounting cup, but the inner peripheral surface of the outer peripheral wall 1 is engaged with the outer periphery of the flange portion. It may be. The degassing tool A2 shown in FIG. 5A is an embodiment of the present invention. In this embodiment, the height of the outer peripheral wall 1 is increased so that a bottomed cylindrical portion composed of the outer peripheral wall 1 and the intermediate wall 2 is formed. The interior space is expanding. Further, an engagement step 28 is provided on the inner surface near the lower end of the outer peripheral wall 1 to engage with the outer periphery of the flange 21. This engagement step 28
Is a second engaging portion of the third aspect.

In this degassing tool A2, the internal space can be used as a cap that covers the outside of the push button 15. Therefore, the push button 15 can be attached to the valve 13 in advance, and the consumer can use the degassing tool A2 immediately by simply removing it. Therefore, it is not necessary to save the push button 15 separately.

When the aerosol product 10 has been used, the push button 15 is pulled out together with the stem 16 and the degassing tool A2 is turned upside down as shown in FIG. As in the case of the embodiment, the push rod 3 opens the valve 13 and degassing is performed. Also in this case, since the whole of the annular projection 4 is engaged with the flange portion 21, it can be stably engaged.

In the degassing tool A3 shown in FIG. 6, the push rod 3 extends downward beyond the intermediate wall 2, and the push rod 3 and its extension 29 have a passage 30 vertically penetrating along the axis. Is formed. The push button 15 is fitted to the upper end of the push rod 3, and the lower end of the extension 29 is fitted to the valve 13. The height of the outer peripheral wall 1 below the intermediate wall 2 is lower than that in FIG. 2, and the lower end of the outer peripheral wall 1 and the bottom surface 12 b of the annular recess of the mounting cup 12 in a state where the extension portion 29 is fitted into the valve 13. The height is set to leave a gap that allows the push button to move up and down. In addition, the position of the annular projection 4 is also set to a position where a gap allowing the push button to move up and down remains with the flange portion 21. This is a push rod 3 and an extension 29
Since the passage 30 is provided in the intermediate wall 2, there is no need to provide a through hole in the intermediate wall 2.

Since the push rod 3 and the extension 29 have the same action as the stem, the aerosol product 10 can be sprayed without removing the degassing tool A3. On the other hand, after the use of the aerosol product, the push button 15 is removed and the degassing tool A3 is turned over as shown in FIG. Combine. As a result, the push rod 3 opens the valve 13 and the push rod 3 and the extension 2
The residual gas can be released through the passage 30 of the ninth embodiment. After that, they can be discarded or recycled.

In the above-described embodiment, the intermediate wall 2 has a disk shape, but may be, for example, a spoke (axle) arranged radially. The intermediate wall according to claim 1 includes such a thing. The outer peripheral wall may have a polygonal shape other than a cylindrical shape as long as the outer peripheral wall engages with a flange portion of the mounting cup. Further, the intermediate wall may have a spoke shape, and the outer peripheral wall may be a plurality of leg pieces provided at the tip thereof in a vertical direction.
