Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an aerosol container lid. More specifically, after discharging the remaining contents from the aerosol container, the aerosol container can be safely disposed of without being bulky, and is an aerosol container in which the contents are discharged visually. The present invention relates to an aerosol container lid that can be discriminated.
[0002]
[Prior art]
In recent years, when the used aerosol container is disposed of, the consumer is required to completely discharge the gas remaining in the aerosol container in advance for the safety of the operation of collecting the waste product. As a method of easily discharging the residual gas from the aerosol container, there is a method using a bottomed cylindrical lid attached to the aerosol container (see Japanese Patent Laid-Open No. 10-53289 or Japanese Patent Laid-Open No. 10-264958). For example, in the lid described in Japanese Patent Application Laid-Open No. 10-264958, as shown in FIG. 8, when disposing of the unnecessary aerosol container 50, the lid 51 is attached in the reverse direction so that the contents can be discharged. In addition, a recessed portion including a fitting portion 54 fitted to the upper winding fastening portion 53 of the aerosol valve 52 and an ejection portion 56 fitted to the stem 55 in the upper wall (upper center portion) of the lid 51. 57 is formed.
[0003]
It also describes that a liquid absorbent such as sponge or tissue is inserted into the lid 51 for use.
[0004]
[Problems to be solved by the invention]
The lid 51 can collect and discharge the discharged contents inside the lid, and the discharged contents do not leak from the lid by using a liquid absorbent.
[0005]
However, since the manufacturing cost is increased due to the material cost and mounting work cost of the liquid absorbent, the inside of the lid 51 has a stem insertion hole (stem tip) 58 when using only the lid that does not use the liquid absorbent. However, since the stem insertion hole 58 and the opening for injecting the contents are in substantially the same position, the contents leak from the stem insertion hole 58 when the aerosol container 50 is removed from the lid 51. For this reason, the collected content leaks to the outside and not only soils hands, clothes, and the floor, but also reduces the amount of collected content that is discharged.
[0006]
Furthermore, if the aerosol container 50 is discarded with the lid 51 attached, the size of the lid 51 becomes an obstacle and the space to the storage case of the aerosol container 50 itself becomes narrow. Therefore, after the contents are discharged, the lid 51 It is also possible to remove the. In this case, when containers collected from other locations are mixed, it is not known from the appearance whether the contents have been discharged. Therefore, it is necessary to shake the containers one by one to check whether they have been discharged. Therefore, the collection work becomes troublesome.
[0007]
In view of the above circumstances, the present invention allows the disposal of the contents remaining from the aerosol container, and then safely discards the aerosol container without bulking the contents. It is an object of the present invention to provide an aerosol container lid that can be identified as an aerosol container.

[0014]
The aerosol valve 3 is mounted on the upper portion of a bottomed cylindrical outer cylinder 5 by a crimping part 8 such as a clinch on a shoulder part 7 attached to a crimping part 6 by double winding, for example. It comprises a cup (not shown) and an injection valve (not shown) supported inside the center of the mounting cup.
[0015]
The lid 1 is composed of two parts, a cap body 9 and a discharge member 10. In this embodiment, the lid 1 is made by injection molding of synthetic resin such as polypropylene, polystyrene or polycarbonate. Only the synthetic resin may be used, and the discharge member 10 may be made of a material similar to the aerosol container, for example, aluminum or tinplate. Thus, by making the discharge member 10 from a material similar to that of the aerosol container 2, the discharge member 10 and the aerosol container 2 can be finally processed without being separated, so that the recovery operation is simplified. The cap body 9 has a bottomed cylindrical shape, and a cylindrical portion 12 and a recessed portion 13 are formed inside the upper wall 11. A locking projection 14 is formed at the opening end of the cap body 9 so as to be able to engage with the crimping portion 6 of the aerosol container 2.
[0016]
The discharge member 10 has an outer shape that is substantially the same as the inner shape of the recessed portion 13, and is detachably fitted to the cylindrical portion 12 and the recessed portion 13 of the cap body 9. The discharge member 10 includes a jet part 16 inserted into the through hole 15 of the cylindrical part 12 and a fitting part 17 fitted into the concave part 13. The stem 4 is fitted into the jet part 16. A recess 18 is formed, and an ejection passage 19 communicating with the recess 18 is formed, and an engagement protrusion 20 is formed in the fitting portion 17 to engage with the crimping portion 8 of the valve of the aerosol container 2. Yes. The distal end portion of the ejection portion 16 protrudes from the distal end portion of the cylindrical portion 12 so as not to interfere with the ejection button 22 fitted to the stem 4, and the ejection port 21 of the ejection portion 16 is the distal end of the cylindrical portion 12. Opened so as not to be blocked. The jet port 21 is directed to the inner surface side of the cap body 9.
[0017]
In the present invention, after all the contents in the aerosol container are discharged, the cap body and the discharge member are separated. At this time, since the discharge member is attached to the aerosol container, it can be determined at a glance that the contents have been discharged, but in this embodiment, the contents in the aerosol container are further discharged. 3, among the surfaces where the discharge member 10 is fitted to the cylindrical portion 12 and the recessed portion 13 of the cap body 9, for example, the aerosol container 2 is placed on the surface of the fitting portion 17. It is preferable to provide display means 23 for indicating that the contents of the item have been discharged. As the display means 23, exhausted, degassed, completed one character or a specific form or pattern other than characters can be used. As this display method, a normal method such as a printing method, a method of sticking a seal, a method of marking, or a method of displaying three-dimensionally by a mold can be used. Alternatively, the display means 23 may be colored the discharge member itself.
[0018]
Next, an example of using the lid of this embodiment will be described. First, as shown in FIG. 4, when disposing of the aerosol container 2 that is no longer used, the lid 1 is turned in the reverse direction and fitted into the stem 4 of the aerosol container 2, and the engagement protrusion 20 of the discharge member 10 is Engage with the caulking portion 8 of the valve. As a result, the pressed state of the stem 4 (the state in which the airtightness of the aerosol container is released) is maintained, and the contents in the aerosol container 2 are jetted from the ejection port 21 onto the inner surface of the cap body 9. At this time, since the discharge member 10 is engaged with the aerosol container 2 by the engagement protrusion 20, the contents can be discharged in a released state. Absorbents such as water-absorbing or oil-absorbing resins, silica gel, calcium chloride and other molded absorbents (sheets, bags filled), cloths, sponges, tissue paper, paper, A gelling agent or a coagulant that gels or hardens the discharged contents may be packed in a lid and used.
[0019]
Next, as shown in FIGS. 5 to 6, after the contents P are discharged, the cap body 9 is separated from the discharge member 10. During the separation, the contents of the cylindrical portion 12 and the injection portion 16 are secured to some extent, so that the contents can be prevented from leaking out from the cap body 9. And the contents can be collect | recovered without polluting a hand and clothes, and the aerosol container 2 and the discharge member 10 can be discarded together. In addition, since the discharged display means 23 is displayed on the discharge member 10, it can be determined at a glance that the contents have been discharged.
[0020]
Next, another embodiment of the present invention will be described. As shown in FIG. 7, the lid 30 according to another embodiment includes a cap main body 33 in which a cylindrical portion 32 is formed on an upper wall 31 having a bottomed cylindrical shape, and is detachable from the cylindrical portion 32 of the cap main body 33. It is comprised from the discharge member 34 which discharges | emits the content of this aerosol container 2, when a press state is maintained when it is inserted in the stem 4 of the said aerosol container 2.
[0021]
The discharge member 34 includes a jet part 36 inserted into the hole 35 in the cylindrical part 32 and a fitting part 37 fitted to the upper part of the valve of the aerosol container 2. 4 is formed, and a discharge passage 39 communicating with the recess 38 is formed. The support portion 40 is engaged with the fitting portion 37 inside the caulking portion 8 of the valve of the aerosol container 2. And an engaging projection 41 is formed.
[0022]
In the present embodiment, an injection port 42 communicating with the ejection passage 39 is formed in the cylindrical portion 32. In the same manner as in the above-described embodiment, the injection port 42 is directed in a direction in which the content to be injected collides with the inner surface of the cap body 33.
[0023]
In the form shown in FIG. 7, the contents collide with the bottom surface 32 a of the cylindrical portion 32 of the cap body 33 through the ejection passage 39, but the length of the ejection passage 39 can be shortened. The distance to the bottom surface 32a of the cylindrical portion 32 can be increased. As a result, the reaction force generated when the contents collide with the bottom surface 32a of the cylindrical portion 32 is small and does not affect the discharge. On the other hand, in the form shown in FIG. 1, the reaction force due to the collision increases because the opening of the ejection passage is close to the collision surface. For this reason, in order to make reaction force small, it is necessary to enlarge a jet nozzle, and there exists a possibility that a jet part may become long.
[0024]
【The invention's effect】
As described above, according to the present invention, after the contents of the aerosol container are discharged, the cap body and the discharge member are separated and the aerosol container and the discharge member are discarded together. Since the cap body does not leak to the outside, the contents can be collected and discarded without contaminating the hands and clothes, and it is also environmentally friendly.
[0025]
Further, since the cap body having a large dimension and the discharge member having a small dimension are separated and only the discharge member is attached to the aerosol container, the recovery of the aerosol container can be performed without bulk.
[0026]
Furthermore, since the aerosol container after a process is in the state with the discharge member, it can be judged that it has been discharged in appearance.
