Description

  The present invention relates to a continuous operation mode setting mechanism used for an aerosol type product, and in particular, for setting an aerosol type product to its stationary mode or an operation mode, for example, a vertically moving type operation member is simply and reliably continued to the continuous operation mode position. In other words, the aerosol type product can be set to a continuous operation mode of a degassing state or a content continuous injection state.

In this specification:
・ The term “operation mode” means a one-to-one correspondence between the user's injection operation on the operation member and the content injection state (the state where the aerosol container valve is opened and the container interior communicates with the external space) Used to indicate
-The term "continuous operation mode" means a continuous injection state (gas, contents, etc.) in which the operation member remains self-held at the previous operation position even after the end of the user's injection operation. Use
・ The term "stationary mode" is used to indicate the state where the aerosol container valve is closed and the container interior is not in communication with the external space.
The term “cover body” is used to indicate a cover member that is attached to an aerosol container body (such as a mounting cap) and that is not removed even in the operation mode of the aerosol container.

  Further, the side of the injection hole of the container contents in the stationary mode is referred to as “front”, and the side opposite to the center of the container plan view is referred to as “rear”. That is, the left direction in FIG. 1 is “front” and the right direction is “rear”.

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

  The continuous injection state and the degassing state are merely differences in application, and as an operating mechanism for aerosol products, the actuator (operating member, stem, etc.) is continuously held in its operating position in each of these states. It is what has been. That is, there is no difference in operation mechanism such as a valve mechanism in each of the states.

  In general, the setting of the degassing mode is necessary only when the used aerosol container is discarded, and is unnecessary in the normal use stage where the contents are still present in the container.

  Therefore, the degassing mode holding mechanism does not become an obstacle to the content injection operation in the normal use stage of the aerosol type product, and it does not disturb the user, and the degassing mode setting operation itself is performed by the user. It should be easy.

  Moreover, when setting an aerosol type product to continuous injection mode over a comparatively long time, it is desirable that a user does not need to perform operation for it continuously.

  Such setting of the operation member to the continuous operation mode position is required to be more accurate, and the present invention meets such a demand.

  The present applicant provides a cam surface for setting a continuous operation mode on a cover body provided with a pair of wall-shaped protection portions for protecting the side surface portion of an operation button (operation member) of a vertical movement type in an aerosol container. The aerosol container is configured such that the operation button is rotated in the circumferential direction of the aerosol container from the stationary mode position to be moved down to the continuous operation mode position along the cam surface and held there. Has been proposed (see Non-Patent Document 1).

  To operate this setting mechanism, the vertical movement type operation button [1] is rotated in the circumferential direction (separate from the normal operation mode setting operation) from the stationary mode position with its knob [1c]. Thus, the pair of projecting portions [1a] formed on the outer peripheral surface of the operation button is held by the horizontal portion [2c] on the lower end side of the cam surface, following the cam surface [2a] on the cover body side. It is only necessary to perform a simple rotation operation.

In the continuous operation mode after the operation of rotating the operation button [1], the injection hole [1b] of the operation button is in a state of facing the pair of standing wall-like portions [2d] for protecting the operation button.
Japan Society for Invention and Innovation Public Technical Bulletin No. 2004-506780 (Fig. 3)

  In the case of the aerosol container continuous operation mode setting mechanism described above, the operation button is moved to the container by using a pair of protrusions formed on the vertical movement type operation button and the corresponding cam surface on the cover body side. By receiving a rotation operation (in the direction), the movement to the continuous operation mode position is ensured, and the convenience is improved.

  However, the operation button set to the continuous operation mode is in a state in which the injection hole faces the tall wall-shaped part in the cover body, so that the gas inside the container moving from the injection hole to the external space or There is room for improvement in that the flow of the content itself is easily disturbed by the wall-like portion.

In the present invention,
(1) In a mechanism in which the continuous operation mode is set by rotating the operation member in the container circumferential direction, the space between the inner and outer wall-shaped portions for protecting the operation member is separated from the gas inside the container in the continuous operation mode. Actively used as an injection passage area for contents,
(2) Alternatively, the cover body itself can be separated into a first cover body area including a high wall-like portion in the opposed state and a second cover body area including a continuous operation mode setting element such as the cam surface. Then, when the continuous operation mode is set, the first cover body area that tends to be an obstacle to the jet flow is removed.
The purpose is to stabilize the jet flow in the continuous operation mode (gas venting, continuous injection of contents).

  It is another object of the present invention to simplify the structure around the operation member by providing the operation member in a one-sided manner in which the rotation operation unit for setting the continuous operation mode can be erected.

The present invention solves the above problems as follows.
(1) Continuous operation in which the operation member is set to the continuous operation mode by the holding action between the operation member for setting the normal operation mode of the aerosol type product and the cover body attached to the container side. In the operation mode setting mechanism,
The cover body includes a housing-like portion formed by at least an inner wall-like portion and an outer wall-like portion for protecting the operation member, and a connecting portion between the inner wall-like portion and the outer wall-like portion. And having a main cover body range with a height that hinders the jet flow of the container contents in the continuous operation mode,
Each of the operation member and the inner wall-shaped portion is continuously operated so that the operation member is moved to the continuous operation mode position by being operated to rotate from the stationary mode position to the container rotation direction and held there. It has a mode setting part,
The casing-like portion is a portion belonging to the main cover body range and corresponding to the injection hole position of the operating member after the turning operation, from the injection hole side to the inside of the casing-like portion. It is assumed that an inner opening portion that leads to the space area is formed and an outer opening portion that leads from the inner space area to the outer space is formed.
(2) In (1) above,
Both the inner wall portion and the outer wall portion are cylindrical portions.
(3) In the above (1) and (2),
In the continuous operation mode, a flow direction guide portion is formed in the internal space area for moving the container contents flowing into the internal space area from the inner through area toward the outer through area. And
(4) In the above (1), (2), (3),
The rotating operation piece is formed on the operating member in such a manner that it can stand up.
(5) Continuous operation in which the operation member is set to the continuous operation mode by the holding action between the operation member for setting the normal operation mode of the aerosol type product and the cover body attached to the container side. In the mode setting mechanism,
The cover body includes at least a wall portion for protection against the operation member, and has a main cover body range having a height that hinders the jet flow of the contents to be stored in the container in the continuous operation mode. ,
The operation member and the wall-like portion are each a continuous operation mode in which the operation member is moved to a continuous operation mode position by being operated to rotate from the stationary mode position in the container rotation direction and held there. It has a setting part,
Each of the first and second cover body areas is connected in such a manner that the second cover body area including the main cover body area can be separated from the first cover body area including the continuous operation mode setting portion. Shall be.

  The subject of the present invention is a continuous operation mode setting mechanism having such a configuration and an aerosol type product provided with the continuous operation mode setting mechanism.

  In the continuous operation mode, the present invention positively uses the space between the inner and outer wall-shaped portions for protecting the operation member as a gas and content injection passage area inside the container. Therefore, the jet flow does not hit the surface of the wall-shaped portion, and passes through this space portion before being discharged to the external space, so that it is not disturbed.

  Further, by passing the gas and contents through the space portion, the passing speed is reduced, and the gas and the like can be gradually released to the external space.

  Further, when the continuous operation mode is set, the cover body region including the high wall-shaped portion that is likely to be an obstacle to the jet flow is removed in the immediate vicinity of the operation member so that the jet flow from the operation member is It will not be disturbed.

  The best mode for carrying out the present invention will be described with reference to FIGS.

  As described above repeatedly, the present invention relates to a mechanism for setting a continuous operation mode such as degassing or continuous injection of contents.

  Whether the continuous operation mode setting mechanism is used in the degassing state or the continuous content injection state is merely a difference in the consciousness of the user, and the operation mechanism of the continuous operation mode setting mechanism itself is any. It is the same even in the state of use.

  That is, according to the present invention, the aerosol-type product injection mechanism is forcibly continuously held in a normal operation mode (set by the operation member) and can be released as necessary.

  For example, even if the user intends to vent the gas and set the continuous operation mode, if the contents remain sufficiently in the container, the content is continuously injected, and the user who notices this cancels the continuous operation mode. You can also.

  In the following description, for convenience of explanation, the gas for injection is simply abbreviated as “gas” on the assumption that the degassing mode is set as necessary.

  It should be noted that the validity of each explanation is guaranteed even if the terms “(injection) gas” and “gas vent” below are replaced with “content” and “continuous content injection”, respectively. is there.

  Here, the stem 3, the operation button 4, the cover body 5 and the cover body 5 'to be described later are made of plastic made of polypropylene, polyethylene, polyacetal, nylon, polybutylene terephthalate, or the like.

  FIG. 1 and FIG. 3 (a) show the stationary mode of the aerosol type product. When the operation surface 4c of the operation button 4 in the stationary mode is pushed down, the stem 3 moves down against the upward biasing force of the coil spring (not shown), and the valve action portion (not shown) is opened. To enter the operation mode. Such a transition mechanism from the stationary mode to the operating mode is well known.

  As a result, the gas in the container main body is directly injected into the external space via the stem 3-passage portion 4a-injection hole 4b. When the user stops the push-down operation, the operation button 4 and the stem 3 are moved upward by the biasing force of the coil spring and returned to the stationary mode position.

  The pair of guided portions 4d of the operation button 4 in the stationary mode such as in FIG. 1 are respectively included in the initial stable portions of the pair of cam grooves 5b of the inner cylindrical portion 5a as illustrated.

  Note that, for example, the dotted line portion directly above the guided portion 4d in FIG. 1B is covered when the operation button 4 and the cover body 5 are paired at the stage before the members are assembled on the container side. This is a space area for inserting the guide portion 4d therein and temporarily fixing the members so as not to be displaced in the circumferential direction.

  In order to shift the aerosol type product from the stationary mode to the continuous operation mode, the protruding piece 4e of the operation button 4 may be rotated in the clockwise direction in FIGS. 1 (a) and 3 (a).

  Along with this turning operation, the pair of guided portions 4d of the operation button 4 move downward along the inclined cam surface 5c of the inner cylindrical portion 5a (cam groove 5b).

  When the guided portion 4d moves to the stable surface 5d of the cam groove 5b, the operation button 4 (and the stem 3 integrated therewith) is held in a state where it is moved down to substantially the same position as in the normal operation mode. As a result, the well-known valve mechanism including the stem 3 and the like is in the “open” state, and the gas inside the container is discharged from the injection hole 4b as in the operation mode.

  On the other hand, the injection hole 4b of the operation button 4 at this time is at a position facing the inflow port 5v formed in the inner high wall portion 5g, as shown in FIG.

  Therefore, after the gas inside the container enters the internal space area A through the injection hole 4b and the inflow port 5v, the gas advances through the internal space area in the direction of the arrow in FIG. 3B by the action of the flow direction guide portion 5y. It is discharged from the front opening 5w to the external space.

  4-6 is explanatory drawing which shows a continuous operation mode setting mechanism (the 2), and respond | corresponds to FIGS. 1-3, respectively.

  The basic difference between this continuous operation mode setting mechanism (part 2) and that of FIGS. 1 to 3 is that the main cover body range extends from the upper end of the outer high wall portion to the operation button side of the cover body ceiling. The downward slope is steep, and an inflow port for the inside of the cover body such as an injection gas during continuous discharge is formed in the ceiling portion.

  4 to 6, new reference numerals are used for the following components, and reference numerals of FIGS. 1 to 3 are used as they are for the other components.

That is, in FIGS.

  The continuous operation mode setting operation (= rotation operation) of the operation button 4 in FIGS. 4 to 6 using this cover body 5 ′ and the cam action between the pair of cam grooves 5b and the guided portion 4d at that time are as follows. This is the same as in the case of FIGS.

  Further, in the continuous operation mode, gas or the like discharged from the injection hole 4d of the operation button 4 enters the internal space area A ′ from the inlet 5v ′, and the flow direction is positively changed by the flow direction guide portion 5y ′. It is the same as in the case of FIGS. 1 to 3 that it moves in the clockwise direction as shown by 6 (b) and is discharged from the plurality of openings 5w ′ to the external space.

  However, the formation portions of the inlet 5v 'and the opening 5w' are different. The cover body 5 ′ in FIGS. 4 to 6 has the same inner cylindrical portion 5 a ′ as a whole and has no inner high wall portion 5 g (like the cover body 5 in FIGS. 1 to 3). .

  In other words, the slope-shaped ceiling 5r 'faces the injection hole 4b in the continuous operation mode, and the opening 5w' serving as the entrance to the internal space A 'is also formed in this ceiling.

Respectively.

  In a normal case where the operation button 11 is used as a pressing operation portion for setting the operation mode, the piece 11a is tilted and the concave portion 11d is engaged with the convex portion 11e. At this time, a predetermined space is secured between the lower surface portion of the piece portion 11a and the top surface portion (of the operation button) facing this.

  And when setting an aerosol type product to a continuous operation mode, the rear-end part of the piece part 11a is lifted using this space, and it sets to the standing state of FIG.7 (b).
