Description

  The present invention relates to an aerosol container cap that is detachably attached to an aerosol container and covers an injection nozzle provided in the aerosol container.

The aerosol container injects the contents together with the filling gas by depressing the injection nozzle. However, if the filling gas is not completely removed, there is a problem that the aerosol container may explode at the time of disposal. Therefore, in order to completely release the filling gas remaining in the container, on the peripheral wall of the cap attached to the aerosol container, two thin lines are formed that divide the peripheral wall into a belt-shaped portion along the circumferential direction. There is one that pushes down the thin line and folds the central part of the belt-like part together with the continuous part that connects the cap and the belt-like part, and pushes down the injection nozzle through the bent central part to release the residual gas (for example, (See Patent Document 1).
JP 2004-315011 A

  However, since the above-mentioned conventional cap has to push out a part of the peripheral wall of the cap, which is a curved portion having high rigidity, the continuous part connecting the cap and the belt-like part and the central part of the belt-like part are pushed together. It is also considered. For this reason, it is difficult to adjust the force to push the cap along the thin wall line, and there is room for improvement in terms of ease of use.

  The present invention has been made in view of these facts, and a problem to be solved by the present invention is to propose a cap that is easy to use for releasing the gas remaining in the aerosol container.

The present invention is a cap of an aerosol container that is detachably attached to an aerosol container and covers an injection nozzle provided in the aerosol container, the cap having a top wall and a peripheral wall connected to the top wall, on the inside, provided with a plurality of ribs extending along the center line of the wall at intervals in the circumferential direction of the peripheral wall, respectively the inner edge of the ribs, the stepped portion at a position lower than the top wall provided, on the step portion, and is characterized in that chromatic an engaging portion for engaging and holding the outer peripheral edge of the cap is different from the plate member. In this case, a slit into which the plate member can be inserted can be formed in the peripheral wall.

Further, the present invention is an aerosol container cap that is detachably attached to an aerosol container and covers an injection nozzle provided on the aerosol container, the cap having a top wall and a peripheral wall connected to the top wall. and, said top wall being defined by breaking portion provided with a plate portion which can be separated by cleavage of the breaking portion, on the inner side, along the center line of the wall at intervals in the circumferential direction of the peripheral wall A plurality of extending ribs are provided, and a step portion is provided at a position lower than the top wall at each inner edge of the rib, and an outer peripheral edge portion of the plate portion separated from the cap is engaged with the step portion. it is characterized in that chromatic engaging portion for engagement holding.

  The cap of the aerosol container according to the present invention is such that after the use of the aerosol container is finished, a plate member different from the cap is engaged and held in the engaging portion provided on the rib on the inner side of the cap, and the aerosol container is mounted in this state. The injection nozzle can be pushed down through the thin plate member. Therefore, according to the present invention, it is possible to provide an easy-to-use cap for releasing the gas remaining in the aerosol container using the cap. In this case, as the plate member, an existing member in daily life such as a coin-shaped medal can be appropriately used.

  According to another aspect of the present invention, after the aerosol container is used, the plate portion is separated from the top wall by cutting the top wall of the cap along the broken portion, and the plate portion is separated from the rib inside the cap. If it is made to engage and hold in the engaging part provided in this, an injection nozzle can be pushed down through a board part. In this case, the plate portion can be easily separated by forming a rupture portion on the top wall instead of the curved side wall of the cap having high rigidity and completely pushing along the rupture portion. Therefore, according to the present invention, it is possible to provide an easy-to-use cap for releasing the gas remaining in the aerosol container using the cap.

  Particularly in the case of the present invention, the plate portion can be carried together with the cap, and can be stored without being lost until the aerosol container is discarded. Furthermore, in this case, since the opening is formed in the top wall of the cap by separating the plate portion, the opening can be used as a gas vent hole.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  The cap 10 includes three vertical ribs 2 extending from the top wall 11 toward the peripheral wall 12 and projecting toward the cap center O on the inner side. Each of the vertical ribs 2 is provided with a step portion 3 at its end portion, and an engaging portion for engaging and holding a plate member 1 (described later) at a lower position inside the cap than the top wall 11 on the side surface of the step portion 3. 4 is formed. As a specific example of the position of the engaging portion 4, the plate member 1 is set to a position where the spray nozzle 53 is pushed down in a state where the cap 10 is put on the aerosol container 50. Further, the form of the engaging portion 4 is not limited, such as undercut fitting or press contact.

  As shown in FIG. 1 (b), the plate member 1 is introduced into the cap 10 from the bottom surface side of the cap 10 through the open side without the vertical rib 2, and the edge 1e of the plate member 1 is engaged with the engaging portion. Engage with 4. As a result, the plate member 1 is held and fixed inside the cap 10. As the plate member 1, a cap member (for example, a coin medal) separate from the cap 10 having a surface area larger than the outer diameter of the injection nozzle 53 can be used.

  According to such a configuration, after using the aerosol container 50, as shown in FIG. 2 (a), the plate member 1 is engaged and held by the engaging portion 4 provided on the vertical rib 2 inside the cap 10, If the cap 10 is attached to the aerosol container 50 as shown in FIG. 2B in the state, the injection nozzle 53 can be pushed down via the plate member 1. Therefore, according to this embodiment, it is possible to provide an easy-to-use cap for releasing the gas remaining in the aerosol container 50 using the cap 10. In this case, as the plate member 1, an existing member in daily life such as a coin medal can be used as appropriate, but the external shape is not limited to a circular shape, and is matched to the size of the cap 10, etc. It can be changed to various shapes such as a rectangle.

  In this embodiment, the gas filled in the cap 10 by venting is provided with a groove 12g that passes through the ridge 12a to the cap opening edge 10e inside the peripheral wall 12 of the cap 10, and the groove 12g Residual gas can be released to the outside by forming a flow path between the winding portion 54 and the tightening portion 54 at the time of mounting. Furthermore, since the plate member 1 can be removed from the engaging portion 4 simply by moving in the direction of the arrow shown in FIG. 2 (a), separation after degassing is easy.

  Further, as a modified example of the first embodiment, a slit S (indicated by a broken line in FIG. 1 (a) and FIG. 2) that allows the inner wall of the cap 10 to communicate with the outside and allows the plate member 1 to be inserted into the peripheral wall 12 of the cap May be formed). In this case, the plate member 1 is inserted into the cap 10 through the slit, and the edge portion 1e of the plate member 1 engages with the engaging portion 4 while pushing down the injection nozzle 53 along the inclined portion 53b of the injection nozzle 53. It is good also as a structure to match.

  3 (a) and 3 (b) are a perspective view of a cap 20 according to the second embodiment of the present invention and a bottom view showing a plate part 5 described later, respectively. FIG. 4 (a) and FIG. FIG. 5 is an explanatory view for explaining the action of the cap 20 when the aerosol container 50 is discarded. In this embodiment, the same parts as those in FIGS.

  The top wall 11 is provided with a plate portion 5 that is partitioned by a line 13 that is thinner than other regions of the top wall 11. The plate portion 5 can be separated from the top wall 11 by being pushed along the line 13 from the top wall 11 by applying an external force.

  Further, inside the cap 20, as shown in FIG. 3B, four vertical ribs 2 extending from the top wall 11 toward the peripheral wall 12 and projecting toward the cap center O are provided. Each of the vertical ribs 2 is provided with a step portion 3 at its end portion, and an engaging portion 4 that engages and holds the plate portion 1 at a lower position inside the cap than the top wall 11 is provided on the side surface of the step portion 3. Is formed. As a specific example of the position of the engaging portion 4, as in the first embodiment, the plate portion 5 is set to a position where the spray nozzle 53 is pushed down in a state where the cap 20 is put on the aerosol container 50.

  As shown in FIG. 3 (a), the plate portion 5 has four protruding-shaped portions 5a that protrude between the vertical ribs 2 while avoiding the vertical ribs 2 in a state of being integrated with the top wall 11. After the push-off, as shown in FIG. 3 (b), it is introduced from the open side without the vertical rib 2 on the bottom surface of the cap 20, and the edge portion 5 e of the protruding portion 5 a is engaged with the engaging portion 4. Thereby, the plate portion 5 is held and fixed inside the cap 20.

  The external shape of the plate portion 5 is not limited to the cross shape as in the present embodiment, but can be changed to various shapes such as a rectangle according to the size of the cap 20 and the like. Further, with the cap attached to the aerosol container, the plate part 5 is pushed from above and rotated in the horizontal direction while pushing down the injection nozzle 53, and the protruding part 5a can be engaged with the engaging part 4. Is possible.

  According to this configuration, after using the aerosol container 50, the plate part 5 is separated from the ceiling wall 11 by pushing the ceiling wall 11 of the cap 20 along the thin line 13, and the plate part 5 is then capped. If the engagement portion 4 provided on the rib 2 inside 20 is engaged and held, the injection nozzle 53 can be pushed down via the plate portion 5. In this case, a thin line 13 is formed on the top wall 11 instead of the peripheral wall 12 of the curved cap 20 having a high rigidity, and the plate part 5 is easily separated because it is completely pushed along the line 13. . Therefore, according to this embodiment, it is possible to provide an easy-to-use cap for releasing the gas remaining in the aerosol container 50 using the cap 20. Note that the break portion according to the present invention may be formed by intermittent connection portions instead of the line 13. Furthermore, the top wall 11 may be curved outward or inward, and its shape is not limited.

  In particular, in the case of this embodiment, the plate portion 5 can be carried together with the cap 20 and can be stored without being lost until the aerosol container 50 is discarded. Further, in this case, since the opening 11a is formed in the top wall 11 by pushing the plate portion 5, the opening 11a can be used as a gas vent hole.
