  In the case of continuously injecting the aerosol contents, it is known to manually press the pressing body assembled to the aerosol container and inject the aerosol contents only during the pressing time. Further, even if the manual pressing operation is not continued as described above, as shown in Patent Documents 1 and 2, the aerosol contents are externally passed through a mechanism that continuously presses the stem of the aerosol container with a single operation. Conventionally, a continuous injection device that enables continuous injection is known.

  The continuous injection device described in Patent Document 1 is provided with a continuous injection mechanism and a pressing body for enabling continuous injection at the upper end of the aerosol container, and by operating the continuous injection mechanism and pressing the pressing body, The valve mechanism is kept open and continuous injection is performed. Moreover, the continuous injection device described in Patent Document 2 is provided with a pressing body provided with a storage chamber for temporarily storing the aerosol contents at the upper end of the aerosol container, and the valve mechanism is opened by pressing the pressing body. After the aerosol content is stored in the storage chamber, only the aerosol content in the storage chamber can be continuously injected to the outside.

  However, since the continuous injection device described in Patent Literature 1 starts continuous injection once, the continuous injection is continued until the entire aerosol content in the aerosol container is injected outside. It was something that could not be stopped. For this reason, continuous injection cannot be performed repeatedly for only an arbitrary required amount, and the application is limited. In addition, in order to start continuous injection, it is necessary to operate not only the pressing body but also the continuous injection mechanism, so that handling during use is complicated.

  Moreover, since the continuous injection apparatus described in Patent Document 2 allows only the aerosol contents stored in the storage chamber to be continuously injected to the outside, the amount of aerosol contents that can be continuously injected at a time is limited. An arbitrary amount of injection was not possible.

  The present invention is intended to solve the above-described problems, and enables continuous injection without continuing the pressing state with a finger or the like by a simple operation of only pressing the pressing body provided in the aerosol container. It is what. In addition, after the continuous injection is started, the pressing of the pressing body can be arbitrarily released to stop the continuous injection, and the pressing of the pressing body and the release of the pressing can be repeated so that the continuous injection is repeatedly performed. Is to make it possible. In addition, after the start of continuous injection, the continuous injection can be continued until the second pressing body is pressed and released, so that the amount of aerosol content that can be continuously injected can be used without being limited. The desired amount is intended to be continuously jetted.

The present invention is fixed to the upper end of the aerosol container, an outer cylinder having a through-hole opened in the center, a nozzle body disposed in the through-hole of the outer cylinder, and a nozzle connected to a stem via a communication path; The nozzle body is slidably inserted into an insertion hole formed in the center, and is rotated with respect to the nozzle body and the outer cylinder while being urged upward by a pressing ridge interposed between the nozzle body and the nozzle body. A rotatable rotating body, and the rotating body and the nozzle body are inserted inside, and an injection port communicating with the nozzle is formed, and is arranged to be slidable vertically in the through-hole of the outer cylinder and pressed downward. By pressing the stem through the rotating body and the nozzle body, the valve mechanism arranged in the aerosol container is opened, and the cylindrical pressing body that can inject the aerosol contents stored in the aerosol container And consist of On the inner surface of the cylinder, a plurality of receiving blades each having a first inclined surface and a second inclined surface having a lower end as a single-flow tapered portion are provided in an annular shape with an insertion interval therebetween, and the lower outer periphery of the rotating body. , the only continuously set the fitting blades the upper end face is V-shaped tapered portion as well as projecting the insertable fitting piece to the pressing member side in the insertion interval, the lower end of the pressing member, under the mating blade matable-formed feed blade end face as Te supermarkets portion of the V-shaped continuous set only, the fitting piece and Hamagoha to face the lower end face of the feed edge When the first pressing body is pressed, the fitting piece of the rotating body is pushed downward by the feed blade below the lower end of the receiving blade, and the stem is pressed to start the injection of the aerosol contents. By releasing the pressing of the pressing body, the fitting piece is arranged on the first inclined surface of the receiving blade, and the valve machine continues. The aerosol contents can be continuously injected while maintaining the valve open state, and the fitting piece located on the first inclined surface is placed below the lower end of the receiving blade by the second pressing of the pressing body. When the second pressing body is pressed down, the fitting piece moves within the insertion interval along the lower end surface of the feed blade and the second inclined surface of the receiving blade, so that the stem pressure is released and the valve is released. The mechanism is closed and the continuous injection of the aerosol contents can be stopped, and the fitting piece can be moved in the same direction every time the pressing body is pressed and released, and the aerosol contents are continuously injected. In addition, the continuous injection can be repeatedly stopped.

  The present invention starts the injection of the aerosol contents by pressing the pressing body provided in the aerosol container, and can continuously continue the injection even if the pressing is released. The aerosol contents can be continuously sprayed with a simple operation. In addition, the continuous injection can be arbitrarily stopped by performing the pressing and releasing of the pressing body again after the continuous injection, and the pressing and pressing of the pressing body for the second time after the continuous injection is stopped. By canceling, the continuous injection can be started again, and the continuous injection and the stop of the continuous injection can be repeated.

  In addition, after the start of continuous injection, continuous injection can be continued until the pressing body is pressed and released again, so that the amount of aerosol content is not limited, and a desired amount for the user can be obtained. It is assumed that continuous injection at a time is possible.

  1 to 9, an aerosol container (1) is an aerosol container. As shown in FIG. 2, the upper end of the aerosol container (1) is a mountain cup ( The valve mechanism (3) fixed to 2) is arranged. Then, the stem (4) disposed in the valve mechanism (3) is passed through the stem gasket (5) disposed on the inner surface of the mountain cup (2) so that the orifice (6) is not pressed when the stem (4) is not pressed. Is closed by the inner peripheral end face of the stem gasket (5), and the orifice (6) is moved and arranged in the housing (7) when the stem (4) is pressed. Further, the orifice (6) communicates with an aerosol content communication path (8) formed from the upper end of the stem (4).

  In this embodiment, the valve mechanism (3) formed as described above is used. However, if the aerosol contents can be sprayed to the outside by pressing the stem (4), the configuration is particularly good. It is not intended to limit. A cylindrical outer cylinder (10) is fixedly disposed at the upper end of the aerosol container (1) provided with the valve mechanism (3) as described above.

  As shown in FIGS. 1 and 2, the outer cylinder (10) has a through-hole (11) in the center, and in the inner peripheral axial direction of the through-hole (11) via an insertion interval (12). A plurality of receiving blades (13) are formed in an annular shape at regular intervals. As shown in FIG. 1, the receiving blade (13) has a first inclined surface (14) and a second inclined surface (15) formed as a single-flow tapered portion at the lower end, and a vertical wall (16) perpendicular to the axial direction. Are provided continuously. The first inclined surface (14) and the second inclined surface (15) are all inclined in the same direction.

  Moreover, as shown in FIG. 2, the nozzle body (17) is arrange | positioned in the through-hole (11) of the said outer cylinder (10). The nozzle body (17) is provided continuously at the upper end of the stem (4), and the nozzle (18) of the nozzle body (17) communicates with the communication path (8) of the stem (4). Therefore, the valve mechanism (3) is opened by pressing the stem (4), and the aerosol contents stored in the aerosol container (1) are discharged from the nozzle port (20) formed at the tip of the nozzle body (17). It can be sprayed outward. Further, as shown in FIG. 1, the tip side of the nozzle body (17) is bent perpendicular to the axial direction.

  The nozzle body (17) is slidably arranged in an up-and-down direction in an insertion hole (22) formed at the center of the rotating body (21). Since the nozzle body (17) is bent at the tip end perpendicularly to the axial direction, the nozzle body (17) is inserted through the tip hole side (22) of the rotating body (21) and removed. It becomes difficult to make it protrude in the direction.

  Therefore, in the present embodiment, as shown in FIG. 2, the nozzle body (17) is divided into upper and lower parts and formed separately, and the rotating body (21) is assembled to the lower part of the nozzle body (17). By assembling the upper part of the nozzle body (17), the nozzle body (17) can be easily assembled in the insertion hole (22) of the rotating body (21). Further, as shown in FIG. 2, a pressing ridge (25) is interposed between the base (23) provided at the lower end of the nozzle body (17) and the upper wall (24) of the rotating body (21). The rotating body (21) is pressed upward.

  Further, as shown in FIG. 1, a fitting step portion (26) is formed in the circumferential direction on the outer periphery of the lower end of the rotating body (21), and a V-shape is formed on the upper end of the fitting step portion (26). The fitting blade (27) formed in the taper part of the mold is continuously formed. Further, on the outer periphery of the fitting step portion (26), a fitting piece (30) whose upper end is a one-flow tapered surface (28) is formed so as to protrude from the fitting blade (27) at three equal intervals. All the tapered surfaces (28) are inclined in the same direction.

  The tapered surface (28) of the fitting piece (30) is formed so as to be inclined in a direction opposite to the first inclined surface (14) and the second inclined surface (15) of the outer cylinder (10). . The fitting piece (30) is formed so that it can be inserted into the insertion interval (12) of the outer cylinder (10), and the protrusion formation length is as shown in FIG. The length reaches the insertion interval (12) of 10).

  A pressing body (31) for pressing and opening the valve mechanism (3) in the aerosol container (1) is provided on the outer periphery of the rotating body (21). The pressing body (31) is formed in a cylindrical shape, houses the rotating body (21) and the nozzle body (17) therein, and has a lower end side disposed in the outer cylinder (10). 10) so that it can slide up and down.

  An elliptical injection port (32) elongated in the axial direction is formed on the side surface of the pressing body (31). The injection port (32) is in a state of communicating with the nozzle (18) of the nozzle body (17) by being disposed so as to face the nozzle port (20) of the nozzle body (17). Further, a feed blade (34) having a lower end surface (33) formed in a V-shaped tapered portion is formed at the lower end of the pressing body (31), and the feed blade (34) is turned into a rotating body (21). ) And the fitting blade (27) and the fitting piece (30).

  Further, on the outer periphery of the lower end of the pressing body (31), as shown in FIG. 1, there are three guide pieces (35) that can be inserted into the insertion interval (12) of the outer cylinder (10) at three equal intervals. It protrudes in the tube (10) direction. Therefore, when the pressing body (31) is pressed, the pressing body (31) can slide in the vertical direction but cannot rotate in the circumferential direction. Therefore, it is possible to smoothly press the pressing body (31) and to always face the nozzle opening (20) of the nozzle body (17) without shifting the injection opening (32) in the circumferential direction at the time of pressing. Can be kept in a different position.

  A case where the aerosol contents are continuously injected in the above-described configuration will be described below. In the non-pressed state of the pressing body (31), as shown in FIG. 2, the orifice (6) is closed by the inner peripheral end face of the stem gasket (5), and the valve mechanism (3) is closed. . Further, as shown in FIG. 6, the fitting piece (30) of the rotating body (21) is moved in the advancing direction of the feed blade (34) of the pressing body (31) within the insertion interval (12) of the outer cylinder (10). It is located on the upper inclined surface (36) inclined upward. Further, the fitting blade (27) and the feeding blade (34) of the rotating body (21) are not completely fitted, and only a part of the upper end surface (37) of the fitting blade (27) is the feeding blade ( 34) is in contact with the upper inclined surface (36), so that a gap is formed between the fitting blade (27) and the feed blade (34). From this state, the first pressing of the pressing body (31) is started as shown below.

  First, when the pressing body (31) is pressed downward against the urging force of the pressing ridge (25), the feed blade (34) provided at the lower end of the pressing body (31) moves downward. Therefore, the fitting piece (30) of the rotating body (21) located on the upper inclined surface (36) of the feed blade (34) of the pressing body (31) when not pressed is, as shown in FIG. It moves downward together with the feed blade (34) within the insertion interval (12).

  Further, as shown in FIG. 3, the nozzle body (17) moves downward through the rotating body (21) by the pressing of the pressing body (31), so that the stem (4) connected to the nozzle body (17). Is pushed downward against the urging force of the stem ridge (38) in the housing (7). Therefore, the orifice (6) that was closed when not pressed also moves downward and is arranged in the housing (7).

  Thereby, the aerosol content in the housing (7) is sprayed outward from the nozzle opening (20) of the nozzle body (17) through the orifice (6) and the communication path (8) of the stem (4). Here, the urging force of the pressing ridge (25) interposed between the rotating body (21) and the nozzle body (17) is stronger than the urging force of the stem ridge (38) mounted in the housing (7). The stem (4) can be pressed downward against the urging force of the stem ridge (38), but until the stem ridge (38) is completely compressed by the downward pressure, the pressure ridge (25) is attached. The rotating body (21) cannot be pressed downward against the force.

  Then, from the state in which the pressing body (31) is pressed until the stem ridge (38) is completely compressed as described above, when the pressing body (31) is further pressed against the urging force of the pressing ridge (25), FIG. As shown, the nozzle body (17) is kept above the upper surface (41) of the protrusion (40) located at the center of the mountain cup (2) while keeping the valve mechanism (3) open. The rotating body (21) has an inner diameter larger than the outer diameter of the protruding portion (40) of the mountain cup (2), so that it is further below the upper surface (41) of the protruding portion (40). Move to.

  Thus, while the nozzle body (17) stops above the protrusion (40) and the pressing body (31) moves further downward, the injection port (32) provided in the pressing body (31). 4 is long in the axial direction, so that the injection port (32) of the pressing body (31) and the nozzle port (20) of the nozzle body (17) are always kept in communication as shown in FIG. Yes.

  Further, the fitting piece (30) that has moved downward within the insertion interval (12) of the outer cylinder (10) by the further pressing of the pressing body (31) is lower than the lower end of the receiving blade (13). Furthermore, it moves downward and gets out of the insertion interval (12). At the same time, the fitting piece (30) moves on the upper inclined surface (36) of the feed blade (34), and in the traveling direction along the upper inclined surface (36) by the urging force of the pressing ridge (25). It moves in a certain circumferential direction, and as shown in FIG. 8, comes into contact with the lower inclined surface (42) adjacent to the upper inclined surface (36) and inclined downward in the traveling direction, and stops.

  Further, along with the movement of the fitting piece (30) in the traveling direction as described above, the fitting blade (27) also moves in the same direction on the upper inclined surface (36) of the feed blade (34), and the fitting piece ( When 30) moves until it abuts against the adjacent lower inclined surface (42) of the feed blade (34), all the upper end surfaces (37) of the fitting blade (27) are the lower end surfaces ( 33), the fitting blade (27) and the feeding blade (34) are in a completely fitted state. Thus, by providing the fitting blade (27) on the outer periphery of the rotating body (21), and moving the fitting blade (27) along the feed blade (34) along with the movement of the fitting piece (30), The rotating body (21) is smoothly and reliably rotated in the traveling direction.

  When the pressing of the first pressing body (31) is released, the rotating body (21) moves upward together with the pressing body (31) according to the urging force of the pressing ridge (25). Then, as shown in FIG. 9, the fitting piece (30) moves upward while being positioned just before the lower inclined surface (42) of the feed blade (34), and the receiving blade of the outer cylinder (10). It abuts on (13) and moves on the first inclined surface (14) of the receiving blade (13). And it moves to the same direction as said advancing direction along the 1st inclined surface (14) with the urging | biasing force of a press ridge (25), and between a 1st inclined surface (14) and a 2nd inclined surface (15). It abuts on the vertical wall (16) located at.

  At this point, the fitting piece (30) can no longer move in the direction of travel, so that it strikes the vertical wall (16) on the first inclined surface (14) against the urging force of the pressing ridge (25). Stop in contact. By stopping the fitting piece (30), the rotating body (21) cannot be moved up to the original position and is fixed on the spot. Therefore, the upper wall (24) of the rotating body (21) is also fixed. By fixing the position, the base (23) of the nozzle body (17) disposed below the upper wall (24) via the pressing ridge (25) cannot be moved upward. For this reason, the nozzle body (17) cannot move upward and remains pressed. Therefore, as shown in FIG. 4, the nozzle body (17) keeps the stem (4) pressed downward, and the valve mechanism (3) maintains the valve open state. It is continuously injected.

  Each time the pressing body (31) is pressed and released, the fitting piece (30) moves in the moving direction, so that the rotating body (21) rotates in the same direction as described above. (31) is non-rotatable by the guide piece (35). Therefore, the pressing body (31) does not rotate with the rotating body (21) by the pressing and releasing of the pressing body (31), and the rotating body (21) rotates independently of the pressing body (31). It is possible.

  In order to stop the continuous injection, the second pressing body (31) is pressed and released. First, when the pressing body (31) is pressed for the second time, the fitting piece (30) arranged on the first inclined surface (14) of the receiving blade (13) as described above becomes the feed blade ( 34) is further pushed down below the lower end of the receiving blade (13) and moves from the first inclined surface (14) of the receiving blade (13) onto the upper inclined surface (36) of the feeding blade (34). Then, as shown by the dotted line in FIG. 8, along the upper inclined surface (36) of the feed blade (34) corresponding to the second inclined surface (15) of the receiving blade (13), the next lower inclined surface (42). It moves in the direction of travel until it touches.

  Then, when the pressing of the pressing body (31) for the second time is released, the rotating body (21) moves upward together with the pressing body (31) according to the urging force of the pressing ridge (25). ) Also moves upward, contacts the second inclined surface (15) of the receiving blade (13), and moves in the traveling direction along the second inclined surface (15).

  Then, as shown by the dotted line in FIG. 9, it slides into the insertion interval (43) adjacent to the insertion interval (12) located before the first pressing of the pressing body (31), and this insertion interval (43). It is arranged on the feed blade (34) located inside. Therefore, the rotating body (21) and the pressing body (31) move upward in accordance with the urging force of the pressing ridge (25) and are restored to the original position, and the valve body (17) is also moved upward as shown in FIG. Move to to restore the original position.

  As a result, the stem (4) is restored to its original position in accordance with the urging force of the stem ridge (38), and the orifice (6) moves upward and closes at the inner peripheral end surface of the stem gasket (5). Stops. Then, by continuously pressing and releasing the pressing body (31) from this state, it becomes possible to start the continuous injection of the aerosol contents again.

  As described above, it is possible to easily stop the continuous injection of aerosol contents and stop the continuous injection only by pressing and releasing the pressing body (31) without requiring any other special procedure. It becomes. Further, as described above, the receiving blade (13) is continuously arranged in an annular shape on the outer cylinder (10), and the fitting piece (30) of the rotating body (21) is pressed and pressed by the pressing body (31). Since the position can be moved in the same direction at each release, the continuous injection of the aerosol contents and the stop of the continuous injection can be repeated any number of times.

  In addition, after the first press body (31) is pressed and released, the continuous injection of the aerosol contents is started and then the second press body (31) is pressed and released until the second press is performed. As a result, it is possible to continuously inject a desired amount of aerosol content at one time for the user.
