Description

  According to the present invention, the push-down type injection operation unit is held in the stationary mode to prevent the content injection operation, and the top surface of the injection operation unit in the operation mode is received and held at that position. The present invention relates to an aerosol injection operation mechanism in which continuous operation modes are individually set.

  That is, in the lock mode in which the injection operation unit is held in the stationary mode position by the lock operation unit, the injection operation unit is reliably prevented from being pushed down to the operation mode position below the stationary mode.

  Further, in the lock release mode in which the injection operation is possible, the injection operation unit that has been pressed down to the position of the operation mode is locked by the lock operation unit, so that the injection operation unit can be operated without the subsequent pressing operation. Is continuously maintained in the operation mode to set the continuous operation mode.

  In the present invention, in particular, when setting the unlocking state of the injection operation unit to the position of the continuous operation mode such as degassing, the user operates the lock operation unit in the unlocking / stationary mode to rotate and stand up. is there.

  This operation of turning to the standing state is clearly different from the operation mode of the lock operation part in the lock mode setting / release operation, and the operation mode of the lock operation part after the rotation operation is different. The standing state is very conspicuous visually.

  The user can instantly visually recognize this standing state as compared to the substantially horizontal state during the sliding operation in the front-rear direction.

  In this way, the continuous operation mode is set by a rotation operation of a shape that is remarkably different from the front / rear direction slide operation of the lock mode setting / release. Further, in order to shift from the lock mode to the continuous operation mode, a two-stage operation of a backward slide operation of the lock operation unit and a subsequent turn-up operation is necessary.

  This prevents the continuous operation mode of the aerosol injection operation mechanism from being set carelessly, and allows the user to instantly recognize the setting state of the continuous operation mode even from a distance.

  Furthermore, the top surface portion of the injection operation portion occupies substantially the entire inner side of the edge top surface of the cylindrical cover cap that exhibits the protective action of the injection operation portion and the like, and is substantially the same height as this edge top surface. Thus, the injection operation unit and the entire top surface around it are flattened.

  In this specification, the term “continuous operation mode” is used to indicate a state in which the injection operation unit is forcibly held at the same downward position as in the operation mode, and gas, contents, and the like are continuously injected. .

  The state in which the injection operation unit is not operated (the state in which the contents are not injected into the external space due to the closing action of the stem valve) is called a stationary mode, and the state in which the injection operation unit is operated (the stem valve is opened). The state in which the contents are jetted into the external space by the action) is called an operation mode.

  Further, the nozzle injection hole side is indicated as “front”, the opposite side is indicated as “rear”, the injection operation part side is indicated as “up”, and the container body side opposite thereto is indicated as “lower”. The directions substantially orthogonal to the front-rear direction in the horizontal plane are called “horizontal” and “left-right”.

  In the continuous operation mode of the aerosol type product, when the container contents are not used up yet, the contents are continuously jetted, and when the container contents are almost used up, the contents are degassed.

  The degassing state and the continuous content injection state are merely differences in application, and as an operating mechanism for aerosol type products, both of them are continuously held by the actuator (operation unit, stem, etc.) in their operating positions. It is what has been. That is, there is no difference in the operation mechanism such as the valve mechanism in each of the states.

  Conventionally, prior to disposal of the aerosol-type product after the contents have been almost exhausted, the push-down type injection operation section is rotated and moved down to its operating mode position to be engaged and held at that position. A degassing mechanism has been proposed (see Patent Document 1).

  The degassing setting operation at this time is a rotation operation in a substantially horizontal plane from the stationary mode position with respect to the push-down type injection operation unit attached to the stem.

  Along with this turning operation, the guided portion of the injection operation portion moves downward while being guided by the downward inclined ceiling surface of the shoulder cover body (cover cap), and is engaged and held by the flat ceiling surface ahead of it. .

JP 2003-165586 A

  As described above, in the case of the conventional degassing setting mechanism that operates based on the rotation operation of the push-down type injection operation unit, the direction of the setting operation is roughly “in the horizontal plane”, and finally the injection operation The part holding the part also becomes a flat ceiling surface in the horizontal rotation operation direction.

  That is, the guided portion of the injection operation unit that moves down to the operation mode position while being guided by the downward inclined ceiling surface of the shoulder cover body is brought into contact with the horizontal ceiling surface that is continuous from the inclined portion, thereby The upward operation of the stationary operation mode is prevented.

  Further, the turning operation for setting the degassing is performed on the injection operation unit that remains attached to the stem.

  Therefore, if an inadvertent force in the direction opposite to the rotation operation of the degassing setting is applied to the injection operation unit in the degassing state, the guided portion of the injection operation unit is inclined upward from the original flat ceiling surface. There was a problem of moving to the ceiling surface and releasing the degassing state.

  In this case, the guided operation portion that has moved to the next side moves upward so that its guided portion follows the upward inclined ceiling surface, and finally returns to the stationary mode position. That is, the degassing state is interrupted.

  On the other hand, if the injection operation unit at the stationary mode position is rotated in the degassing setting direction due to mischief or the like, the aerosol injection mechanism erroneously shifts to the degassing state. .

Therefore, in the present invention, without setting the horizontal rotation operation of the injection operation unit when setting the continuous operation mode,
(11) The lock operation unit keeps the push-down type injection operation unit in the stationary mode and prevents the content injection operation, and the top surface of the operation mode after the lock mode is released A continuous operation mode that holds and holds in that position is selectively set,
(12) The lock mode is set / released based on the forward / backward slide operation of the lock operation unit, and the continuous operation mode such as degassing is set / released using the forward / backward slide operation of the lock operation unit. It is executed on the basis of the rotation standing / falling operation with clearly different aspects,
(13) In the continuous operation mode such as degassing, the lock operation part is set to its upright state.
The aerosol injection operation mechanism is used.

  Further, the top surface portion of the injection operation unit occupies substantially the entire inner side of the edge top surface of the cylindrical cover cap that exhibits the protective action of the injection operation unit and the like, and the edge operation is performed in the stationary mode position. The height is set to be approximately the same as the surface.

This
(21) Ensures individual operation of setting / canceling the lock mode based on the forward / backward sliding operation and setting / canceling the continuous operation mode based on the rotation up / down operation, as well as degassing and continuous injection of contents To prevent accidental setting of the state,
(22) Easier to see the continuous operation mode setting with the standing operation of the lock operation part.

Respectively.

  Here, the injection operation unit 1, the cover cap 4 and the lock operation unit 5 are made of plastic such as polypropylene, polyethylene, polyacetal, nylon, polybutylene terephthalate, and the like.

  The stem 2 and the housing 3b are made of, for example, plastic or metal. The container body 3 and the mounting cup 3a are, for example, metallic.

The basic features of the illustrated aerosol injection operation mechanism are:
(41) In the lock mode (FIGS. 1 and 2) in which the lock operation portion 5 is pushed forward, the connection portion lower end surface 5d is held by the terrace-like portion 4f of the cover cap 4 and then connected. The upper end surface 5e of the injection unit abuts against the lower end surface of the arcuate hanging portion 1h of the injection operation unit 1 to prevent the injection operation unit from being pushed down,
(42) In the unlocking / resting mode (FIGS. 3 and 4) in which the lock operation unit 5 of FIGS. The engagement holding state with the arcuate hanging part 1h is released, and the entire rectangular columnar part 5g of the lock operating part 5 is located behind the left and right end / rear end side lower surface 1d of the laterally wide part 1c of the injection operating part 1. Move until the position is exposed (see FIG. 3), and enable the injection operation unit to be pressed down.
(43) In the degassing state (FIGS. 5 and 6) in which the lock operation unit 5 is turned upright in the B direction while the injection operation unit 1 shown in FIGS. The front end surface 5h of the rectangular columnar portion 5g is in contact with the left and right end / rear end side upper surfaces 1e of the wide width portion 1c of the injection operation portion, and the injection operation portion is continuously held in the operation mode position after the depression operation. To
That is.

  As described above, in the lock mode of FIGS. 1 and 2, the lower end surface of the arcuate hanging portion 1 h of the injection operation unit 1 abuts the rear connection unit upper end surface 5 e of the lock operation unit 5 and the rear of the lock operation unit. The connecting portion lower end surface 5 d is in contact with the terrace-like portion 4 f of the cover cap 4. That is, the injection operation unit 1 is engaged and held by the cover cap 4 via the lock operation unit 5 at least in the pressing operation direction.

  For this reason, the push-down operation of the injection operation unit 1 becomes impossible, and erroneous operation of the operation mode setting or the continuous operation mode setting can be reliably prevented.

  In the lock mode of FIGS. 1 and 2, the shaft portion 5 f of the lock operation portion 5 is positioned at the front end portion of the front-rear direction opening 4 d of the cover cap 4.

  When the user holds the pair of gripping depressions 5j of the lock operation unit 5 of FIGS. 1 and 2 and slides backward, the lock operation unit is moved from the position of the lock mode to the lock shown in FIGS. Move to the release / still mode position.

  When moving in the rearward direction, the lock operating portion 5 is configured such that the shaft portion 5f is guided by the front-rear direction opening portion 4d of the cover cap 4 and the connecting portion lower end surface 5d is rearward from the terrace-like portion 4f of the cover cap 4. Separate.

  1 and 2, the shaft portion 5f is also opened in the front-rear direction by the locking convex portion 4e in the same manner as in the unlocking / resting mode of FIGS. It is held at the front end portion of 4d.

  Therefore, the user can obtain a click feeling associated with the shaft portion 5f being set to the front position in the lock mode and moving rearward from the front position.

  3 and 4, the shaft portion 5f of the lock operation portion 5 is securely held by the rear end portion of the front-rear direction opening portion 4d, that is, the rear portion of the locking convex portion 4e. .

  Further, as clearly shown in FIG. 3, the front portion of the rectangular columnar portion 5g of the lock operation portion 5, that is, the position located below the left and right end / rear end side lower surface 1d of the wide width portion 1c (injection operation portion 1) until then. The front part which has been moved to the rear separated position of the lower surfaces of the left and right ends and rear ends.

  The rear connecting portion lower end surface 5d and the rear connecting portion upper end surface 5e of the lock operating portion 5 are spaced rearward from the terrace-like portion 4f of the cover cap 4 and the arcuate hanging portion 1h of the injection operating portion 1, respectively. 5 g is separated rearward from the left and right end / rear end side lower surface 1 d.

  Due to the separation of the rear connecting portion lower end surface 5d, the rear connecting portion upper end surface 5e, and the quadrangular columnar portion 5g, the pushing operation of the injection operation unit 1 can be executed without being blocked.

  When the user presses the depression depression portion 1a of the injection operation unit 1 set to the unlock / static mode in the A direction, the injection operation unit is centered on the outward rotation shaft 1k in FIG. Rotate clockwise. At this time, the connecting portion (upstream end portion) of the content passage area 1m with the stem 2 is displaced downward.

  With the displacement of the connecting portion, the stem 2 also moves downward while resisting the elastic force of the coil spring, and the stem valve (stem hole and stem gasket) shifts from the closed state to the open state. The shift operation mechanism including the coil spring and the stem valve is well known.

  In the operation mode in which the well-known stem valve is in the open state, the contents of the container body 3 pass through the housing 3b, the stem 2 and the contents passage area 1m through the hole 1p of the nozzle 1n to the external space by the action of the injection gas. Is injected into the area.

  When the user stops pressing down the injection operation unit 1, the stem 2 and the injection operation unit 1 integrated with the stem 2 are moved upward by a known elastic action in the upward direction of the coil spring. Return to the unlocked / still mode state.

  With this return, the above-described stem valve (stem hole and stem gasket) shifts from the previously opened state to the closed state. Of course, the container body contents are not injected into the external space after the stem valve is shifted to the closed state.

  5 and 6, as described above, the lock operation unit 5 is erected in the B direction while pushing down the ejection operation unit 1 in the unlocking / stationary mode of FIGS. 3 and 4, and the erection is performed. The state is retained.

  That is, the user does not continue the pressing operation to the injection operation unit 1 but continuously holds the injection operation unit at the pressing operation position (operation mode position) by the lock operation unit 5 in the standing state.

  As described above, the degassing state of FIGS. 5 and 6 is set by the turning operation of the lock operation unit 5 from the substantially horizontal state to the standing state.

  This turning operation is clearly different in operation mode from the sliding operation in the front-rear direction in setting / releasing the lock mode.

  Therefore, for example, when the user performs an operation of shifting from the unlocking / resting mode of FIGS. 3 and 4 to the locking mode of FIGS. 1 and 2, the degassing state (continuous operation) of FIGS. It is easy to avoid an erroneous operation that shifts to (Mode).

  Further, the difference in appearance between the lock operation unit 5 in FIGS. 1 to 4 and the lock operation unit 5 in FIGS. 5 and 6 is also remarkable. That is, the degassing lock operation unit 5 shown in FIGS. 5 and 6 stands up, and the lock operation unit 5 shown in FIGS. 1 to 4 is arranged in a substantially horizontal state in the front-rear direction.

  Therefore, even if the user looks at the aerosol type product from a distance, the user can instantly and surely recognize that it is “set / not set” in the degassing state.

  The shaft portion 5f, which is the rotation center when the lock operation portion 5 is erected in the B direction after the push-down operation of the injection operation portion 1, is used to lock the front-rear direction opening 4d as its front-rear movement guide portion. It is stably held at the rear end side portion behind the convex portion 4e.

  Therefore, the shaft portion 5f held at the rear end portion of the front-rear direction opening 4d is positioned at the rear end when the lock operation portion 5 is turned upright in the B direction and turned down in the C direction. It acts as a reliable center of rotation without deviating from the front.

  As described above, the user rotates the lock operation unit 5 in the B direction while pressing the ejection operation unit 1 in the unlock / rest mode in the A direction and moving the rear side downward. To shift to a degassing state. The user performs this turning operation, for example, by holding the gripping depression 5j.

  Along with the turning operation in the B direction, the square columnar portion 5g of the lock operation portion 5 rises in such a manner that its front end face 5h changes from the forward state to the downward state.

  Finally, the front end surface 5h moves to a position immediately above the left and right end / rear end side upper surface 1e of the wide width portion 1c of the injection operation portion 1, and abuts on the upper surface portion to push down the contact injection operation portion. Is kept in the same operating mode.

  In this holding state, due to the elastic action of a well-known coil spring that urges the injection operation unit 1 upward, the left and right end / rear end side upper surfaces 1e of the injection operation unit strongly contact the front end surface 5h of the square columnar part 5g. It touches. It goes without saying that the user does not have to continue the pressing operation of the injection operation unit 1 after the contact.

  The timing at which the user stops the turning and standing operation in the B direction for setting the degassing state with respect to the lock operation portion 5 is the contact between the opposed curved surface portion 5b of the arm portion 5a and the edge top surface 4h of the cover cap 4 For example, when you get a feel.

  5 and 6, the well-known stem valve (stem hole, stem gasket) is set in the open state in the same manner as the operation mode in the content injection state, and the hole of the nozzle 1 n from the container body 3 is set. An injection passage up to 1p is secured. The residual gas in the container body 3 is injected into the external space area by the arrow path in FIG.
