  Conventionally, when an aerosol product is discarded after the contents filled in the aerosol container are used, if the contents remain in the aerosol container, there is a risk of causing an explosion accident due to expansion of the injection gas. there were. Therefore, as shown in Patent Documents 1 to 16, a content discharge device for discharging the entire content remaining in the aerosol container has been proposed.

  For example, in Patent Document 1, an engagement protrusion is provided on the outer periphery of a push button that presses the stem, and an engagement receiving portion that can engage the engagement protrusion is connected to the inner periphery of the one-touch cap. Is formed. When the aerosol product is used, the push button is pushed down to inject the contents with a push-down amount that does not engage the engagement protrusion with the engagement receiving portion. When the use of the contents is finished and the aerosol container is discarded, the push button is greatly depressed to engage the engagement protrusion with the engagement receiving portion, and the push button is maintained in the pressed state. It was possible to discharge the entire contents in an open state.

  Also, in Patent Documents 2, 5, 6, and 8, the push protrusion and the one-touch cap are formed with the engagement protrusion and its engagement receiving portion. However, the engagement protrusion and the engagement reception portion are not used during normal use. Arranged at the engagement position, there is no blockage of restoration by pressing or releasing the push button. When the aerosol container is discarded, the engagement protrusion and the engagement receiving portion are engaged by rotating the push button in the circumferential direction while pressing the push button. By this engagement, the pressing state of the push button is maintained, and the entire content can be discharged.

  In Patent Documents 3, 4, and 7, an engagement protrusion or an engagement groove is provided on the push button, and an engagement member that can be engaged with or inserted into the engagement protrusion is provided on the one-touch cap. . Then, when the aerosol container is discarded, after the push button is pressed, the engagement member is bent or elastically deformed, and the engagement member is engaged with the engagement protrusion of the push button or inserted into the engagement groove. It was fixed and maintained in a pressed state, and the entire contents could be discharged.

  Further, in Patent Document 9, by rotating a rotation lever provided on the push button, the engagement protrusion of the rotation lever is engaged with the engagement receiving portion of the one-touch cap in the pressed state of the push button. Can be discharged continuously. On the other hand, in Patent Document 10, a plate-like pressing member is provided on the inner surface of the head cover that covers the push button, and an engaging step portion that can be pressed by the pressing member is formed on the upper surface of the push button. In addition, the pressing member and the engaging step portion are always arranged at the non-engaging position, and at the time of disposal, the head cover is rotated and the engaging step portion is pressed by the pressing member, thereby depressing the push button and The pressed state was maintained, and the entire contents in the aerosol container were discharged.

  In Patent Documents 11 and 12, a nail-like pressing member for maintaining the pressing state of the push button is manufactured, and this pressing member is attached to a cap connected to the aerosol container. When the aerosol container is discarded, the cap is once removed, the nail-like pressing member is inserted into the through hole or the insertion groove inside the cap, and the cap is mounted on the aerosol container again. With this attachment, the pressing member presses the push button to open the valve mechanism and maintains the pressed state of the push button, so that the entire contents in the aerosol container can be discharged.

  Also, in Patent Documents 13 and 14, the pressing member of the push button is formed separately, and at the time of disposal, the pressing member is appropriately attached to the cap, the push button is pressed by this pressing member and the pressing state is maintained, The entire contents could be discharged.

  Further, in Patent Document 15, a plurality of protrusions directed to the inner peripheral wall side of the one-touch cap are provided on the push button, and two types of deep and shallow notches for fitting the protrusions are provided. In a normal use state, the protrusion of the push button is fitted into the deep notch, the one-touch cap is fitted into the aerosol container, and the content can be discharged by pressing the push button with a finger or the like. Further, at the time of disposal, when the projection is fitted into the shallow notch portion and the one-touch cap is fitted into the aerosol container, the content can be continuously ejected, and the entire remaining content can be discharged.

  Further, in Patent Document 16, at the time of disposal, the one-touch cap is turned upside down, the push button is rotated and adjusted so that the injection port faces the inner surface side of the one-touch cap, and the inverted aerosol container is fitted into the one-touch cap. In this way, it is possible to discharge the entire contents while maintaining the state where the pressing piece presses the push button, and to suppress the discharge of the contents to the outside by causing the injected contents to collide with the inner wall of the one-touch cap. It is.

  However, in the above-mentioned Patent Document 1, the push-down amount of the push button is limited by the engaging protrusion, and the push button cannot be pushed down during normal use, and it is difficult to perform mass injection of the contents. There is also a possibility that the engagement protrusion and the engagement receiving portion may be erroneously engaged due to excessive depression of the push button. In Patent Documents 2, 5, 6, and 8, rotating in the circumferential direction while pressing down the push button requires a large force, and fine adjustment of the alignment is difficult. Further, in Patent Documents 3, 4, and 7, the engaging member protrudes from the one-touch cap and gets in the way, or in combination with the injection pressure of the contents and the elastic restoring force of the engaging member, There is also a possibility that the engagement is released.

  Further, in Patent Document 9, there is a concern that the structure of the rotating lever is complicated and expensive, or that the rotating lever is lost due to dropping off. Further, in Patent Document 10, it is necessary to form the head cover firmly in order to maintain the pressing of the push button, and there is a possibility that the cost is increased and the aerosol device is bulky.

  Also in Patent Documents 11 to 14, it is necessary to form the pressing member separately, which increases the cost, and it is difficult to check the inside of the cap to which the pressing member is attached, and the pressing member and the push button are accurately aligned. It was difficult.

  In addition, the above Patent Documents 1 to 14 all require a complicated configuration, make the apparatus expensive, and require a complicated procedure for use.

  Moreover, in patent document 15, since a complicated operation | work is required in order to provide the protrusion of a pushbutton and two types of notches, there exists a possibility that cost may become high. In addition, since each of the above embodiments discharges the discharged contents directly into the atmosphere, the discharged contents may contaminate the user and the surroundings. In addition, as in Patent Document 16, there are those that temporarily collide the discharged contents with the inner wall surface of the cap to suppress the release to the outside, but the contents that collided with the inner wall surface are scattered, Since it flows out from the inner wall surface, it was extremely insufficient to prevent the contents from diffusing.

  Accordingly, the present invention is intended to solve the above-described problems, and when discarding an aerosol product whose use has been completed, the entire amount of the content remaining in the aerosol container is reliably discharged. Make it possible. And, it is intended to prevent an explosion accident of aerosol products by discharging the entire contents. In addition, by discharging the contents in a discharge chamber in which release to the outside can be easily suppressed, at least diffusion of the liquid component into the atmosphere can be significantly suppressed. Further, an inexpensive apparatus is to be formed by using a simple configuration.

  In order to solve the above-described problems, the present invention provides an outer peripheral wall that is removably engaged with a shoulder portion of an aerosol container, and an outer peripheral wall that is formed inside the outer peripheral wall with a constant interval therebetween. In a one-touch cap consisting of a pair of inner walls that are connected together via an upper wall and have a discharge chamber formed between them and the outer wall, the nozzle communicates with the stem at the interval between the inner walls. The push button is arranged, a fitting recess that can be fitted in an inverted state with the push button removed from the stem is formed on the inner peripheral wall, and the stem of the aerosol container is used as the push button in the inverted fitting state of the push button. In this connection state, the stem can be pressed, the remaining contents can be discharged, and the tip of the nozzle faces the inner surface of the outer peripheral wall when the push button is fitted into the fitting recess. In the exhausted aerosol Object is intended to be stored in the discharge chamber to be formed at the outer peripheral wall and inner peripheral wall.

  In addition, the push button may be connected to the one-touch cap via a hinge portion.

  In addition, the one-touch cap may be provided with an engagement rib that is detachably engaged with the shoulder portion of the aerosol container on the inner periphery of the lower end.

  The present invention is configured as described above, and when performing normal injection of the aerosol contents, the injection can be performed by pressing the push button with a finger or the like. When normal injection is completed and the entire aerosol content is injected to dispose of the aerosol container, the outer peripheral wall is removed from the aerosol container, and at the same time, the push button removed from the stem is fitted into the fitting recess in an inverted state. Then, when the aerosol container is fitted to the one-touch cap, the stem is connected to the push button and the aerosol container is pressed, the entire amount can be injected.

  In this way, since the total amount injection of the aerosol contents is performed by means completely different from the normal injection, the user does not inject the total amount by mistake during the normal injection, and the total amount of the contents in the aerosol container is sure Injection can be performed. In addition, by making sure that the entire amount can be injected, it is possible to prevent an explosion accident that may occur when the aerosol product is discarded. In addition, the discharged aerosol content is sprayed and stored in the discharge chamber covered with the outer peripheral wall, inner peripheral wall, upper wall of the one-touch cap and the upper end of the aerosol container, so that the aerosol content hardly diffuses to the outside and is safe. The entire amount can be injected. In addition, an inexpensive apparatus can be formed by using a simple configuration as described above.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. (1) is a one-touch cap. As shown in FIGS. 2 and 3, the lower end of the outer peripheral wall (2) is connected to the shoulder (4) of the aerosol container (3). Can be engaged via the engagement rib (5).

  In the configuration as described above, when the aerosol content (15) is normally injected, as shown in FIG. 3, when the stem (6) is pushed down via the push button (7), the aerosol content (15) Passes through the nozzle ridge (14), and is ejected from the tip of the nozzle (16) to the outside, resulting in a normal injection state. In this normal injection state, the push button (7) is not provided with any mechanism other than the normal injection, and therefore the stem (6) is normally injected even if the stem (6) is pressed strongly. It is not possible to perform any operation other than that, and there is no state of full injection or the like. Therefore, the user can perform normal injection with peace of mind without requiring fine adjustment of the push-down width of the stem (6).

  Next, when the use of the aerosol container (3) by the normal injection is finished and the entire quantity is injected for disposal of the aerosol container (3), as shown in FIG. 4, the one-touch cap (1) and the aerosol container The engagement of (3) is released and the push button (7) is removed from the one-touch cap (1) and the stem (6).

Then, the aerosol container (3) is placed in an inverted state and press-engaged with the one-touch cap (1).

  Then, as shown in FIG. 1, the communication port (12) of the push button (7) and the stem (6) of the aerosol container (3) are connected, and the push button (7) is struck by pressing of the aerosol container (3). The stem (6) is pressed to allow the remaining aerosol contents (15) to be discharged. This pressing state is continued by engaging the shoulder (4) of the aerosol container (3) and the engaging rib (5) in the spraying state. Thereby, even if it cancels | releases the pressing force to an aerosol container (3), it can be set as the total amount injection state by which the aerosol content (15) is continuously injected from the front-end | tip of a nozzle (16).

  In addition, the aerosol content (15) is injected into the discharge chamber (11) covered with the inner peripheral wall (8), the outer peripheral wall (2), the upper wall (10), and the aerosol container (3) in the total amount injection state. Therefore, the aerosol content (15) sprayed from the tip of the nozzle (16) hits the inner surface side of the outer peripheral wall (2) and is discharged into the discharge chamber (11) and hardly sprays and diffuses outside. At the same time, the abutted aerosol content (15) is stored in the discharge chamber (11). Next, when the injection of the entire amount is finished, the aerosol container (3) and the one-touch cap (1) are disengaged and the aerosol contents stored in the discharge chamber (11) of the one-touch cap (1) ( 15) can be discarded, the load on the surrounding environment can be reduced, and safe and reliable full-injection can be performed.
