Description

  The present invention relates to an apparatus for discharging residual contents of an aerosol container for discharging the entire residual contents when disposing of an aerosol product.

  Conventionally, when an aerosol product is discarded after the contents filled in the aerosol container are used, if the contents are left in the aerosol container, it may cause a problem such as an explosion accident due to expansion of the injection gas. was there. Therefore, as shown in Patent Documents 1 and 2, a residual content discharging apparatus for discharging the entire content remaining in the aerosol container has been proposed.

That is, the residual content discharging apparatus described in Patent Documents 1 and 2 is provided with an overcap, and this overcap is provided with an annular cut line formed by a perforation on the lower end side of the peripheral wall. ing. Further, a protrusion is provided on the inner top surface, and an upper annular protrusion and a lower annular protrusion are formed on the inner peripheral surface at two upper and lower positions via a planned cutting line. During normal use, the lower annular protrusion of the overcap is engaged with the aerosol container to connect and fix the overcap to the aerosol container, and the protrusion on the inner side of the overcap and the push button provided on the aerosol container are contactless. Kept in a state. When discharging the residual contents, cut the overcap scheduled cutting line and cut off the lower end portion of the peripheral wall, and then engage the upper annular protrusion of the overcap with the aerosol container to place the overcap into the aerosol container. By fixing the connection, the protruding portion of the overcap presses the push button to maintain this pressed state, and discharges the remaining contents.

  However, the residual content discharging apparatus described in Patent Documents 1 and 2 is in the state where the overcap is connected and fixed to the aerosol container during normal use, and when the strong force to the aerosol container is applied to the overcap. The lower annular protrusion that has engaged with the container expands due to elastic deformation, gets over the engagement part of the aerosol container, moves further downward, and the upper annular protrusion that is located above the lower annular protrusion is the aerosol. There is a possibility that a situation of engaging with the container may occur. In this case, the push button is pressed by the protrusion provided on the inner side of the overcap to maintain this pressed state, and the entire amount is injected by mistake.

  Therefore, the present invention is intended to solve the above-described problems, and the user does not accidentally discharge the entire amount during normal use, and maintains the pressed state of the push button when discharging the residual contents. It is intended to ensure that the entire contents in the aerosol container can be discharged.

  In order to solve the above-described problems, the present invention is fixed to an aerosol container and has a shoulder cover formed with an annular groove having an upper end opened by an outer peripheral wall and an inner peripheral wall, and can be moved up and down within the inner peripheral wall of the shoulder cover. A push button connected to the stem of the aerosol container and an overcap whose lower end is connectable in the annular groove of the shoulder cover, and a part of the lower end annular wall at the lower end of the overcap An opening that allows a cut-out projection to be formed by cutting the cut-off line to be provided in the bottom wall of the annular groove of the shoulder cover. In normal use, the lower end of the overcap is abutted against the bottom wall of the annular groove in the shoulder cover without detaching the planned cutting line of the overcap. The push button is housed in the overcap to keep the pushbutton in a non-pressed state, and when the residual contents are discharged, the cut line of the overcap is cut to form a cutout protrusion, and the cutout protrusion is formed on the bottom wall. The push button can be pressed through the overcap by inserting it into the opening, and the overcap is connected and fixed to the shoulder cover in the pressed state of the pushbutton, thereby maintaining the jetting state of the content and discharging the residual content. Is possible.

  In addition, the overcap has an inner peripheral protrusion projecting on the inner peripheral surface, and the inner peripheral wall of the shoulder cover is engaged with the inner peripheral protrusion of the overcap when discharging the residual contents, and the push button is pressed. A lower outer peripheral projection that can maintain the injection state may be provided on the outer peripheral surface.

  The present invention is configured as described above, and includes an overcap and a shoulder cover. During normal use, the lower end of the overcap is abutted against the bottom wall of the annular groove formed in the shoulder cover, and the overcap is The push button is kept in a non-pressed state by being detachably connected to the shoulder cover. In addition, when discharging the residual contents, the cut line provided at the lower end of the overcap is cut to form a notch protrusion, and the notch protrusion is inserted into the opening provided in the annular groove of the shoulder cover. Thus, by connecting and fixing the overcap to the shoulder cover, the pressing state of the push button is maintained through the overcap, and the entire contents can be discharged reliably.

  Therefore, even when the overcap connected to the shoulder cover is pressed strongly against the aerosol container during normal use, the lower end of the overcap is inserted into the annular groove in the shoulder cover and hits the bottom wall. Therefore, the movement of the lower end is limited by the bottom wall of the annular groove. Therefore, even if the overcap is strongly pressed by mistake, the overcap does not press the push button, and the push button is not pressed. Therefore, a residual content discharging apparatus capable of easily and reliably discharging the entire amount of the contents after the use is completed without any accidental injection during normal use, with a simple configuration and low cost. Obtainable.

  In the following, an embodiment of the present invention will be described with reference to FIGS. 1 to 5. (1) is a cylindrical overcap, which is formed in a U-shaped cross section as shown in FIG. The cutting line (2) of the mold is formed by perforations. Then, by cutting this planned cutting line (2), it becomes possible to form a U-shaped notch protrusion (3) protruding at the lower end of the overcap (1) as shown in FIG. Further, a pair of the planned cutting lines (2) are formed and arranged symmetrically with the overcap (1) by 180 degrees. Further, as shown in FIG. 4, an annular inner peripheral protrusion (4) is provided on one end of the inner peripheral surface of the overcap (1) at the lower end side.

  Further, as shown in FIG. 2, a cylindrical shoulder cover (6) is attached to the upper end of the aerosol container (5). The shoulder cover (6) has the lower end of the inner wall (10) formed inside the shoulder cover (6) in a state where the outer wall (7) is abutted against the shoulder (8) of the aerosol container (5). It is engaged and fixed to the outer periphery of the mounting cup (11) of the aerosol container (5). A cylindrical inner peripheral wall (12) is formed at the center of the shoulder cover (6), and a push button (20) connected to the stem (18) of the aerosol container (5) is formed in the inner peripheral wall (12). Is slidable up and down. Further, on the outer peripheral surface of the inner peripheral wall (12), an annular upper outer peripheral protrusion (16) and a lower outer peripheral protrusion (which are engageable with the inner peripheral protrusion (4) formed on the inner surface of the overcap (1) ( 17) are formed at regular intervals above and below.

  A cylindrical outer peripheral wall (13) is integrally formed with the inner peripheral wall (12) on the outer side of the inner peripheral wall (12) via a bottom wall (14). The inner peripheral wall (12), outer peripheral wall (13), and bottom wall (14) form an annular groove (15) having a U-shaped cross section, and an overcap ( It is assumed that the lower end of 1) can be inserted. When the lower end of the overcap (1) is inserted into the annular groove (15) and the lower end surface (22) of the overcap (1) is abutted against the bottom wall (14), the overcap (1 ) And the upper outer peripheral protrusion (16) of the inner peripheral wall (12) engage with each other, and the top plate (23) of the overcap (1) does not press the push button (20). The formation position of each member is adjusted in advance so that Further, as shown in FIG. 3, the bottom wall (14) of the annular groove (15) has two arcuate openings (21) that allow the insertion of the notched protrusion (3) of the overcap (1). The part is formed through.

  In the case of the above-described configuration, the normal use will be described first. Without cutting the planned cutting line (2) of the overcap (1), the lower end of the overcap (1) is connected to the annular recess of the shoulder cover (6). Insert into the groove (15). Thereby, as shown in FIG. 4, the lower end surface (22) of the overcap (1) abuts against the bottom wall (14) of the annular groove (15), and the push button (20) is not pressed. At this time, the inner peripheral protrusion (4) of the overcap (1) is engaged with the upper outer peripheral protrusion (16) of the inner peripheral wall (12) of the shoulder cover (6), and the aerosol container (5) is laid sideways. It is difficult for the overcap (1) to fall out of the shoulder cover (6) even when it is turned upside down.

  Further, as described above, the lower end of the overcap (1) is inserted into the annular groove (15), and the lower end surface (22) of the overcap (1) is the bottom wall (14) of the annular groove (15). Therefore, even if the overcap (1) is carelessly strongly pressed toward the aerosol container (5), the bottom wall (14) of the annular groove (15) can cause the lower end of the overcap (1). Movement is restricted. Therefore, the situation where the push button (20) is pressed through the overcap (1) is unlikely to occur, and the non-pressed state of the push button (20) is more reliably ensured that the entire amount is not accidentally injected during normal use. Can keep.

  Next, when the residual contents are discharged, first, as shown in FIG. 5, the cut line (2) of the overcap (1) is cut and a notch protrusion (3) is formed at the lower end of the overcap (1). Are formed in two places. And this notch protrusion (3) is made to face the opening part (21) formed in the bottom wall (14) of the annular groove (15), and the lower end of the overcap (1) is annularly formed on the shoulder cover (6). By inserting into the concave groove (15), the notch protrusion (3) is inserted into the opening (21) as shown in FIG. And by inserting the notch protrusion (3) into the opening (21) in this way, the push button (20) can be pressed via the overcap (1).

  Then, under the pressing state of the push button (20), as shown in FIG. 1, the inner peripheral protrusion (4) of the overcap (1) and the lower outer peripheral protrusion (17) of the inner peripheral wall (12) are engaged. By doing so, the overcap (1) is connected and fixed to the shoulder cover (6). The inner peripheral protrusion (4) and the lower outer peripheral protrusion (17) can be engaged with each other so as not to be disengaged against the urging force of the stem (18). Thereby, since the pressing state of the push button (20) is continued, the injection state of the contents is maintained, and the residual contents can be discharged reliably.

  As described above, it is possible to prevent an explosion accident of the aerosol container (5), which may occur when the aerosol product is discarded, by reliably injecting the entire remaining content. Further, as described above, the cut-out protrusion (3) is formed on the overcap (1) and the opening (21) is formed in the annular groove (15) of the shoulder cover (6). An easy and inexpensive product can be obtained.
