Description

  The present invention relates to a shut-off trigger mechanism or the like in which contents on a container body side are discharged from a discharge port to an external space area by a content release operation of a trigger lever.

In particular, when the trigger lever content discharge operation (pull operation) is not performed, the trigger lever covers and protects the content discharge port,
Furthermore, the lock mode that prevents the content discharge operation in the stationary mode and the unlock mode that enables the content discharge operation in the same mode can be selectively set by operating the locking members such as the stopper and the slider. It relates to the shut-off trigger mechanism and the like.

  In this specification, regarding the positional relationship between front, rear, left and right, the operation target portions 7a and 17a of the trigger levers 7 and 17 are referred to as “front”, and the opposite side, for example, the hole 7b and the convex shaft portion 17b are referred to as “rear”. ”.

  A direction that is substantially orthogonal to the front-rear direction in a horizontal plane is defined as “left-right”. The vertical direction is also referred to as “vertical”, and an arbitrary direction substantially orthogonal to the vertical direction is referred to as “horizontal”. Here, in addition to the “left-right direction”, the “front-rear direction” can also be referred to as a “lateral direction” with respect to the “vertical direction (up-down direction)”.

  For example, FIGS. 1 to 4 and FIGS. 10 to 13 are cross-sectional views in the front-rear direction, the upright portion 6m of the collar member 6 extends in the left-right direction and the vertical direction, and the connecting shaft-shaped portion 19c of the spring member 19 is in the left-right direction. It extends to. Moreover, the horizontal cylindrical part 5b etc. of the stem joint 5 consist of a cylindrical part of the front-back direction.

  As described above, the stationary mode in which the contents of the trigger lever are not released is classified into a lock mode in which the operation of the trigger lever is blocked and an unlock mode in which the operation is not blocked. These are called “stationary lock mode” and “stationary unlock mode” as necessary.

  In addition, a state where the content discharge port is covered and not exposed to the outside space area is referred to as a “shut-off state”, and a state where the content is released by the content release operation of the trigger lever is referred to as an “operation mode”.

  In the stationary mode, the applicant covers and holds the content discharge port and the like with the trigger lever and the dome-shaped collar member, and the content discharge port is exposed by the movement of the trigger lever according to the operation mode setting operation. Then, the stem moves down to the operation mode position, and the trigger lever automatically returns to the stationary mode position by the action of the elastic member when the content discharge operation is released, that is, the content discharge port is covered with the trigger lever. A shut-off trigger mechanism of the above type has been proposed (see Patent Document 1).

Japanese Patent Application No. 2012-181846

  The proposed shut-off trigger mechanism covers and protects the content discharge port with the operation member and the collar member that holds the shut-off trigger mechanism in the stationary mode, and is used for content discharge while resisting the elastic force of the trigger lever. By performing a pulling operation (rotating operation), the contents discharge port is exposed, and if this pulling operation is canceled, there is an advantage of automatically returning to the stationary mode.

  In the present invention, as a further function of the shut-off trigger mechanism having such an advantage, a trigger lever pulling operation (content releasing operation) blocking function in a stationary mode is provided, and thus the external space region of the shut-off trigger mechanism is originally provided. It is an object of the present invention to prevent inadvertent transition of an exposed state of a content discharge port covered so as not to be exposed.

Further, the downwardly protruding convex portion 16p of the collar member 16 enters the lower concave portion 18k of the slider 18 while being relatively elastically compressed and deformed with the convex portion directly below the lower concave portion 18k.

  In the procedure of (115) above, the pair of convex shaft portions 17b of the trigger lever 17 are spread outward while being guided by the rearward inclined surface 16w of the collar member 16 to the engagement hole portion 16e. Moving.

In the stationary mode where the trigger lever 17 is not operated (see FIGS. 10 and 11),
(121) The stem 14 is moved up by the elastic force of the coil spring 14d, and the stem gasket 14c is held in the housing 13 in a known state in which the lateral hole portion 14a is closed,
(122) The trigger lever 17 is shown in the clockwise direction by the elastic force of the spring member 19 (elastic force weaker than that of the coil spring 14d) placed on the semicircular plate-like portion 15e of the stem joint 15 in engagement with the stem 14. And the upper end surface portion of the trigger lever is held in contact with the upper end frame portion 16u of the collar member 16,
(123) The linear lower end surface 17f and the curved angular end surface 17g of the trigger lever 17 (plate-like hanging portion 17e) in this abutting and holding state are sufficiently spaced above the bulging portion 19d of the spring member 19 above. .

  From the start of the pulling operation of the trigger lever 17 in the unlock mode (see FIG. 11), the stem joint 15 and the stem integral therewith are separated by the distance between the linear lower end surface 17f and the curved angular end surface 17g and the bulging portion 19d. There is a so-called delay until 14 moves to the content discharge state by being driven downward while resisting the strong elastic force upward of the coil spring 14d.

  During this delay, the stem lever 15 urged upward by the strong elastic force of the coil spring 14d does not move downward, and the trigger lever 17 is moved around the convex shaft portion 17b of the spring member 19. It rotates counterclockwise in FIG. 10 while resisting weak elastic force.

  As the trigger lever 17 rotates, the discharge port of the stem joint 15 that has been covered by the trigger lever is exposed to the external space (see FIG. 12).

FIG. 10 shows a stationary lock mode (trigger lever pulling operation prevention), and the slider 18 at this time is
(131) The top plate portion 18a is held in contact with the curved step portion 16v of the collar member 6 (upper frame portion 16u), and its front end portion 18c is also held in contact with the upper frame portion 16u.
(132) The upper step portion 18g abuts and holds the lower end portion of the connecting shaft-like portion 19c of the spring member 19 integrated with the Ω-like portion 17h of the trigger lever 17,
(133) The lower step portion 18h abuts and holds the linear lower end surface 17f of the trigger lever 17,
(134) The arc-shaped step portion 18m abuts and holds the lower end surface of the large-diameter cylindrical portion 15c of the stem joint 15.

  Thus, in the stationary lock mode in which the slider 18 is moved in front of the upper end frame-shaped portion 16u, the connecting shaft-shaped portion 19c of the spring member 19, the linear lower end surface 17f of the trigger lever 17, and the large-diameter cylinder of the stem joint 15 Movement of a total of three places of the shape part 15c is prevented. That is, the user cannot pull the trigger lever 17.

  In order to cancel the rotation prevention of the trigger lever 17 of FIG. 10 and shift to the stationary unlock mode (trigger lever pulling operation is possible) of FIG. 11, the user may move the slider 18 backward.

  By reversing the slider 18 set on the curved step portion 16v of the collar member 16, the slider according to the above (132), (133), (134), the spring member 19, the trigger lever 17, and the stem All the contact and holding states between the joints 15 are released (see FIG. 11).

  That is, the shut-off trigger lever mechanism in the stationary lock mode in FIG. 10 shifts to the stationary unlock mode in FIG.

  As described above, the elastic force of the spring member 19 that biases the trigger lever 17 in the clockwise direction in FIGS. 10 to 13 is sufficiently smaller than that of the coil spring 14d that biases the stem 14 upward.

Due to this difference in elastic force, when the trigger lever 17 is pulled backward (counterclockwise) in the stationary unlock mode of FIG.
(141) First, the spring member 19 integrated with the trigger lever is displaced via the connecting shaft-shaped portion 19c in such a manner that the upper portion of each elastic acting portion 19a is moved downward (see FIG. 12).
(142) In accordance with the trigger lever pulling operation after the end of the displacement of the elastic action portion 19a, the coil spring 14d is displaced downward in a manner resisting the elastic force (see FIG. 13).

That is, as the trigger lever 17 is pulled,
(151) At the initial stage where only the weak elastic force spring member 19 is displaced without displacing the highly elastic coil spring 14d, the discharge port 15j of the nozzle 15h is exposed to the external space, but the discharge port The contents are not jetted from
(152) The state in which the contents are not jetted is that when the trigger lever 17 rotates counterclockwise around the convex shaft portion 17b, the curved corner end surface 17g of the bulging portion 19d of the spring member 19 Continue until it touches the top surface (see Figure 12)
(153) After the curved corner end surface 17g and the bulging portion 19d come into contact with each other, the stem joint 15 on which the spring member 19 is placed and the stem 14 integral with the stem member 15 are moved from the curved corner end surface 17g of the trigger lever 17. In other words, receiving the driving force,
(154) The stem 14 receiving this driving force moves downward while resisting the upward elastic force of the coil spring 14d,
(155) The shut-off trigger mechanism shifts to the well-known operation mode of the content discharge state by the downward movement of the stem 14 (see FIG. 13).

  When the stem joint 15 is displaced in the vertical direction between the stationary mode and the operation mode, the convex upward step portion 15n of the nozzle 15h corresponding to the front end portion thereof remains engaged with the downward step portion 16t of the collar member 16. Yes, the free intermediate portion of the flexible L-shaped cylindrical portion composed of the vertical cylindrical portion 15a and the horizontal cylindrical portion 15b is deformed.

  In the operation mode of FIG. 13, due to the deformation of the stem contact portion (inner portion) of the stem gasket 14 c that has closed the horizontal hole portion 14 a of the stem 14, the horizontal hole portion changes from the closed state so far to the open state. It has changed.

  At this time, the contents of the container main body 11 are “the horizontal hole portion 14a of the stem 14—the intermediate passage area 14b of the stem 14—the vertical cylindrical portion 15a of the stem joint 15 and the horizontal cylindrical portion 15b—nozzle. It is discharged to the external space area through the 15h discharge port 15j ". The contents discharge operation based on the action of the injection gas is well known.

When the user releases the pulling operation to the rear of the trigger lever 17,
(161) The stem 14, the stem joint 15 integrated therewith, the spring member 19 and the like are driven upward by the elastic force of the coil spring 14d, and the valve action portions (the lateral hole portion 14a and the stem gasket 14c) are moved up to that point. Transition from open to closed,
(162) The trigger lever 17 in the free state is rotated clockwise by the elastic force of the spring member 19 so that the upper end surface portion of the trigger lever comes into contact with the upper end frame-like portion 16u of the collar member 16. Transition to the state.

  That is, the shut-off trigger mechanism in the operation mode of FIG. 13 transitions to the stationary unlock mode of FIG.

  By moving the slider 18 forward in this stationary unlock mode, the shut-off trigger mechanism returns to the initial state of FIG.

Of course, the present invention is not limited to the illustrated embodiment, for example,
(171) Forming concave and convex portions for sliding the fingers on the operation target portions 7a and 17a of the trigger levers 7 and 17,
(172) When the operation mode setting operation of the trigger lever 17 is performed, the curved corner end surface 17g abuts on the upper surface of the semicircular plate-like portion 15e of the stem joint 15 and directly drives it downward.
(173) The lock holding target of the slider 18 in the lock mode is
