JP-A-10-86984

  Conventionally, when an aerosol product is discarded after using the contents filled in the aerosol container body, if the contents remain in the aerosol container body, a problem such as an explosion accident due to expansion of the injection gas occurs. There was a fear. In order to solve this problem, for example, as shown in Patent Document 1, a content discharge device for discharging the entire content remaining in the aerosol container body is known.

  As a conventional example of this content discharge device, as shown in FIGS. 13 and 14 of Patent Document 1, a protruding portion serving as a shaft protrudes from the inner surface of the top plate of the overcap connected to the aerosol container, and this protruding portion is What supported the eccentric position of the press body is known. During normal use, the pressing body is arranged in a non-contact state with the push button. When discharging the entire remaining content, the pressing body is decentered from the protrusion and moved to the position of contact with the push button, the overcap is fixed to the aerosol container, the push button is pushed down and the stem is pressed, The contents are discharged.

  As another conventional example, as shown in FIGS. 17 and 18 of Patent Document 1, an annular protrusion is provided on the inner surface of the top plate of the overcap, and a U-shaped pressing body is attached to and detached from this protrusion. A possible arrangement is known. Then, during normal use, the pressing body is attached to the protrusion by associating the opening of the pressing body having a U-shaped cross section with the push button, and when the entire remaining content is discharged, the opening side of the pressing body is connected to the protrusion. On the side, the bottom is placed on the push button side and mounted. Then, by connecting the overcap and the aerosol container in this mounted state, the pressing body pushes down the push button to press the stem and discharge the remaining contents.

  However, in the contents discharging apparatus as shown in FIG. 13 and FIG. 14 of Patent Document 1, since the pressing body is pivotally supported by the protruding portion at the eccentric position, it is performed with fingers or the like when discharging the remaining amount of the remaining contents. It was difficult to rotate the pressing body. In addition, since the pressing body rotates about the eccentric shaft, the pressing body may be accidentally detached from the projection during this rotation, or if the force is adjusted incorrectly, the projection that uses the shaft may be deformed or broken. In some cases, it could not rotate and could not be fully discharged.

  Further, in the embodiment shown in FIGS. 17 and 18 of the above-mentioned Patent Document 1, when removing the pressing body from the protrusion of the cap in order to discharge the whole amount, the side wall of the pressing body is folded by mistake when adjusting the force. It has been difficult to put the pressing body into the overcap with a small diameter by putting it in the overcap with fingers or the like and attaching it to the protrusion.

  Therefore, in order to solve the above-described problems, the present invention makes it possible to reliably discharge the entire content remaining in the aerosol container when the aerosol product whose use of the aerosol content is finished is discarded. By expelling the entire amount of aerosol contents, it is intended to prevent an explosion accident that may occur when the aerosol container is discarded. Further, it is intended to enable reliable discharge of the entire remaining content by simple work.

  In order to solve the above-described problems, the present invention provides an outer peripheral wall detachably engaged with an aerosol container, a top plate disposed at the upper end of the outer peripheral wall, and an inner surface of the top plate. A storage part with a circularly projecting inner peripheral wall at a position deviated from the center, and an upper surface of a push button that is rotatably stored in the storage part and fixed to the stem of the aerosol container, is inserted, and is not in contact with the upper surface. An overcap is formed by a rotating body provided with a pressing portion that can press the push button adjacent to the insertion opening, and the upper surface of the push button is inserted into the insertion opening during normal use of the aerosol container. When the aerosol contents are ejected and ejected, the overcap is removed from the aerosol container, the rotating body is rotated, and the pressing portion is made to correspond to the upper surface position of the push button. By engaging the flop aerosol container, pressing state of the push button is maintained by the pressing portion of the rotating body, and makes it possible to discharge the residual contents.

  Further, the inner peripheral wall is provided with a support rib in the circumferential direction on the storage portion side of the tip, and can be supported by the support rib so that the rotating body stored in the storage portion does not come off from the storage portion. Also good.

  Further, an adjustment rib for positioning the rotating body stored in the storage portion and a corresponding concave groove may be provided on the storage portion side of the inner peripheral wall and the outer periphery of the rotating body.

  Since the present invention is configured as described above, during normal use, the insertion opening of the rotating body of the overcap is made to correspond to the upper surface of the push button, and the upper surface of this push button is inserted into the insertion opening of the rotating body. As a result, the push button is brought into a non-contact state, and the aerosol content is brought into a non-injection state. Then, when discharging the entire amount of the remaining contents in order to discard the aerosol container, remove the overcap from the aerosol container, insert a finger or the like into the insertion opening of the rotating body, rotate the rotating body, The overcap is engaged and fixed to the aerosol container with the pressing portion and the upper surface of the push button corresponding to each other. By this engagement and fixation, the push button is pushed down by the pushing portion and the pushed state is maintained, and the discharge and ejection state of the residual contents continues. Therefore, the residual contents can be easily discharged and ejected by rotating the rotating body with a simple operation of fingers.

  In addition, since the push button is pressed down by the pressing body while the overcap and the aerosol container are engaged with each other, the discharge state of the residual content can be continued. Therefore, once in the discharge injection state, the user does not need to touch the aerosol container until the entire discharge of the residual contents is completed, and the entire discharge of the residual contents can be performed safely and reliably. In addition, by making sure that the entire amount can be discharged, it is possible to prevent an explosion accident that may occur when the aerosol product is discarded. Further, since the residual content injected in this total discharge hits the inner surface of the outer peripheral wall of the overcap, it is not sprayed outside and scattered, and the total discharge can be performed safely.
