JP5046328B2 - Content discharge mechanism for multiple connected containers, and aerosol and pump-type products equipped with this content discharge mechanism - Google Patents

Description

  The present invention relates to a content discharge mechanism for a plurality of connected containers in which the contents of each of the plurality of containers are discharged to an external space via a common output member by an operation mode setting operation of a single operation member for the plurality of connected containers. In particular, the timing of shifting to the operation mode in the valve mechanism of each container is to be synchronized.

  In the present specification, the side of the ejection port for the container contents in the normal operation 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, for example, the left direction in FIG. 2 is “front” and the right direction is “rear”.

  For convenience of explanation, the following description is based on an aerosol type product, but the subject of the invention is not limited to this, and a pump type product is also included in the subject.

  In general, when setting a plurality of containers in a connected state to an operation mode, it is desirable to minimize the occurrence of a timing state in which only a part of them is switched to the mode. Responds to requests.

  2. Description of the Related Art Conventionally, there has been proposed an aerosol device having a content discharge mechanism for allowing the contents of the connected first and second aerosol containers to be injected substantially simultaneously by the operation mode setting operation of a single operation member. (See Patent Document 1).

In the case of this content release mechanism, by using an operation member of a type that rotates about a wide (long) hinge portion in a line direction connecting the stems of the first and second aerosol containers, the aerosol container These stems are intended to be moved downward evenly.
JP 2000-109150 A

  In the conventional contents discharge mechanism for simultaneously injecting the contents of the connected first and second aerosol containers in this way, the operation member itself for each stem of the container at the time of the operation mode setting operation. In other words, the movement balance is ensured, that is, the operation member is prevented from coming into contact with either one of these stems.

  And, by ensuring the movement balance of the operation member itself, the simultaneous injection of the contents of each container can be expected because each stem of the container in a connected state, or a nozzle member driven by the operation member integrally therewith It is assumed that the positions and operation modes of (output member) and the like are equal when viewed from the operation member.

  Therefore, in the case of a connected container that does not satisfy this precondition, there is a problem that it is difficult to simultaneously inject the contents of the containers.

  Therefore, in the present invention, the relationship between the operation mode setting operation mode of the user with respect to the operation member and the movement mode of each stem of the connected multiple containers in accordance with the setting operation is represented by the user's operation force and the movement stroke of the operation member. Compared to the change, the movement distance of the stem increases rapidly. In other words, this increase practically causes the stems of the containers to enter the operation mode instantly (regardless of the position and operation mode described above). The purpose of this is to ensure the simultaneous injection of the contents even in the case of a connected plural container that does not satisfy the above-mentioned preconditions.

  In addition, the operating member is rotated in the opposite direction to the operation mode position and is actively held in the protect mode position in such a manner that the stem cannot be driven, so that the operating member is not at the time of the original operation target. The purpose is to prevent malfunction such as driving to the operation mode.

  In addition, the operation member in the protect mode position covers the injection port side portion of the content output member from the upper side, so that the injection port side portion is inadvertently driven and shifts to the operation mode. The purpose is to prevent this.

The present invention solves the above problems as follows.
(1) Along with the operation mode setting operation of a single operation member (for example, an operation lever 7 to be described later) with respect to a plurality of connected containers (for example, a container having a container body 1, 1 ′ described later), When the contents are discharged to the external space through a common output member (for example, a discharge member 4 described later) and the operation force for the operation mode setting operation is weak, the operation member is temporarily held to temporarily move the operation member. In the mechanism for releasing the contents of a plurality of connected containers, including a fine operation preventing means for preventing
The operating member is
A drive portion (for example, a projecting action portion 7c described later) for shifting the output member to the operation mode position;
The fine operation preventing means includes
A hanging piece (for example, a hanging piece 7d described later) as a blocked portion formed on the operation member;
An opening area (for example, an opening area to be described later) of a container cover body (for example, a cover body 5 to be described later) as an integrated part with the plurality of containers in a mode of temporarily holding the hanging piece portion at a stage where the operation force is weak. A temporary holding portion formed in 5d),
The temporary holding part is
A wall-like portion (for example, an inner wall-like portion 5e described later) continuing downward in the opening area;
A protruding portion (for example, a protruding portion 5f described later) that is formed on the wall-shaped portion and stops the lower end portion of the hanging piece portion that has entered the opening area;
An elastic deformation portion (for example, an elastic property described later) that is formed on the container cover body so as to face the wall-like portion and sandwiches both side portions of the hanging piece portion that has entered the opening area between the wall-like portion. A deformable tab 5g),
When the operation force is weak, the drooping piece portion is interposed between the wall-like portion and the elastic deformation portion by the elastic force of the elastic deformation portion in a state where the lower end portion is stopped by the protruding portion. Pinched,
Only when the operating force exceeds a weak level, the drooping piece moves over the protruding portion while moving the elastically deforming portion away from the wall-like portion in a manner that resists the elastic force. The output member is configured to move to the operation mode position in conjunction with the operation member by moving downward.
Use the connected multi-container content release mechanism.

  The subject matter of the present invention is a content release mechanism having the above-described configuration, an aerosol type product equipped with the content release mechanism, and the like.

  In the present invention, the relationship between the mode of operation mode setting operation of the user with respect to the operation member and the movement mode of each stem of the connected multiple containers accompanying the setting operation is as follows. Since the movement distance of the stem is set so as to increase abruptly compared to the change in stroke, even in the case of connected multiple containers that do not satisfy the above-mentioned preconditions, it is possible to ensure the simultaneous injection of each content. Can be achieved.

  In addition, since the stem is actively held in the protect mode position in a state in which the rotation type operation member is rotated in the direction opposite to the operation mode position, it is not at the time of the original operation target. In addition, it is possible to prevent malfunctions such as the operation member being inadvertently driven to shift to the operation mode.

  Further, since the operation port at the protection mode position covers the injection port side portion of the content output member, the malfunction occurs such that the injection port side portion is inadvertently driven and shifts to the operation mode. Can be prevented.

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

  FIG. 1 to FIG. 3 show the contents of the connected multi-container container that have a fine operation preventing function in which the operation member does not move at the initial stage when the operation mode setting operation force for the user operation member is weak (rotation operation). It is explanatory drawing which shows a discharge | release mechanism.

  Here, FIG. 1 is a perspective view of the stationary mode, FIG. 2 is a sectional view of the stationary mode, and FIG. 3 shows the operating mode.

  In addition, it has shown that the component (for example, annular recessed part 1a) of the following reference numbers with an alphabet is a part of component (for example, container main body 1) of the numerical part of the said reference number in principle.

1-3,
1, 1 'is a container body (in a connected state) of an aerosol type product containing the contents and the gas for injection described later,
1a and 1a ′ are annular concave portions formed on the upper end side of the outer peripheral surface of the container body for fitting and holding a cover body 5 described later,
2 and 2 'are mounting caps attached to the open ends of the container bodies 1 and 1'.
3 and 3 ′ are stems that are components of a known valve mechanism (not shown),
4 is a discharge member for discharging the contents attached to the stems 3 and 3 ′,
4a and 4a ′ are individual passages directly connected to the output side of the stems 3 and 3 ′,
4b is a common passage in which each of the individual passages merges,
4c is an injection port which is an output end of the common passage,
5 is a cylindrical cover body (shoulder cover) having a connecting function for the container main bodies 1 and 1 ′ and a front upper missing portion corresponding to the discharge member 4 and a rear upper missing portion corresponding to the operation lever 7 described later. ),
5a is a plurality of rib-like portions for fitting with the annular concave portions 1a, 1a ′ to hold the container bodies 1, 1 ′ in a connected state,
5b is a part of the rib-shaped portion, and a stepped portion that comes into contact with the upper surface portion of the connected mounting cap 2, 2 ′;
5c is a part of the rib-shaped portion, and a protruding projection for fitting into the connected annular concave portions 1a and 1a ′,
5d is an opening area (penetration part) for preventing fine operation into which a later-described hanging piece part 7d enters,
5e is an inner wall-like portion that continues downward from the side close to the stem of the opening area,
5f is a projecting portion that is formed on the outer peripheral surface of the inner wall-shaped portion and temporarily holds the tip portion of a hanging piece portion 7d to be described later.
5 g is an elastically deformable tab formed in a manner facing the wall-like portion,
5h is a step for locking and holding a C-shaped lid, which will be described later,
6 is a C-shaped lid attached to the cover 5 in a detachable manner,
7 is an integrally molded product with the C-shaped lid 6 and is a rotary type operation lever that drives the discharge member 4 to the operation mode position;
7a is an operation surface when the user performs a pressing operation,
7b is a thin-walled base that is the center of rotation during operation,
7c, three projecting action portions that contact the upper surface portion of the discharge member 4 to drive the member to the operation mode position;
7d is a wide hanging piece that enters the opening area 5d of the cover body 5 and is temporarily held;
Respectively.

  Here, the stems 3 and 3 ', the discharge member 4, the cover body 5, the C-type lid 6 and the operation lever 7 are made of plastic made of polypropylene, polyethylene, polyacetal, nylon, polybutylene terephthalate, or the like. The container body 1, 1 'and the mounting cap 2, 2' are made of metal.

  When the user depresses the operation surface 7a of the operation lever 7 shown in FIGS. 1 and 2 (stationary mode), the operation lever tends to rotate clockwise around the base portion 7b.

  On the other hand, the lower end portion of the hanging piece 7d of the operation lever 7 is originally fixed to the projecting portion 5f of the cover body 5 (inner wall portion 5e), and the both surface portions thereof are the inner wall portion 5e and the tab 5g. Is temporarily held in a state of being sandwiched by the elastic force of the tab.

  Therefore, this temporary holding state continues at an initial stage where the user's pressing load on the operation surface 7a is small.

  When the pressing load increases and reaches a predetermined level, the hanging piece 7d of the operating lever 7 outwards (to the right in FIG. 3) in such a manner that the tab 5g of the cover body 5 resists its elastic force. It moves over the protrusion 5f of the inner wall portion 5e while moving.

  As shown in FIG. 3 (operation mode), the operating lever 7 that has moved over the protrusion 5f moves downward. As a result, the three projecting action portions 7c of the operating lever 7 respectively drive the discharge member 4 and the stems 3 and 3 'integrated therewith downward.

  Due to the downward movement of the stems 3 and 3 ′, the valve action part of a well-known valve mechanism (not shown) is opened, and the contents of the container main bodies 1 and 1 ′ are “individually connected to the stem internal passage-discharge member 4”. It flows into the common passage 4b of the discharge member 4 through the passages 4a and 4a '"and is discharged from the injection port 4c to the external space.

  As described above, the timing at which the discharge member 4 and the stems 3 and 3 ′ integrated with the discharge member 4 are moved downward to enter the operation mode is the initial stage when the user starts pressing the operation lever 7 and the force is still weak. It is a stage where the pressing force of the user reaches a predetermined load.

  That is, the user's pressing load increases, and the hanging piece 7d of the operating lever 7 moves over the protruding portion 5e of the inner wall portion 5c while moving the tab 5f of the cover body 5 against the elastic force. It is a later stage.

  Therefore, the discharge member 4 is pushed down stepwise by a plurality of (three) protruding action portions 7c of the operation lever 7 at a stroke.

  Therefore, the related mechanisms after assembly such as the stems 3 and 3 ′, the discharge member 4 and the operation lever 7 are assumed to be in contact with the timing of the contact between the stems 3 and 3 ′ of the respective container main bodies and the projecting action portions. Even when the movement speed of each of the stems varies, the timing of transition to the operation mode of the valve mechanisms of the container bodies 1 and 1 ′ is set substantially simultaneously.

  As a result, it is possible to substantially prevent only the contents of one of the container main bodies 1 and 1 ′ from being ejected at the initial stage of the user's operation with respect to the operation lever 7.

  It should be noted that the three projecting action portions 7c of the operating lever 7 are set at an intermediate portion of the stems 3 and 3 'and a symmetrical position around the center portion.

  Therefore, an equal pressing force can be applied from the operation lever 7 to the two stems 3, 3 '(discharge member 4).

  FIGS. 4 to 7 are set so that the movement distance of each stem of the container is rapidly increased by the action of the cam in the connected plurality of containers as compared to the change of the movement stroke of the operation member of the user. It is explanatory drawing which shows the content discharge | release mechanism which made the stem open simultaneously with the timing of this rapid increase practically.

  4 is a perspective view of the stationary mode, FIG. 5 is a sectional view of the stationary mode, FIG. 6 is an operation mode, and FIG. 7 is a protection mode.

  The correspondence between the constituent elements of the reference numbers with alphabets and the constituent elements of the numeral portions of the reference numbers is the same as in the case of FIGS.

  4 to 7, the components of the container body 1, 1 ′, the mounting caps 2, 2 ′, the stems 3, 3 ′ and the discharge member 4 are the same as those in FIGS. 1 to 3, and other covers are used. The following new reference numbers are used for the body, connecting member and operating lever. Note that a cylindrical peripheral surface upper surface portion 4d is also newly used.

  The content discharge mechanism of the connected multiple containers of FIGS. 4 to 7 substantially prevents only one of the contents from being injected at the user's operation stage, similar to that of FIGS. To do. However, the means for preventing injection of only one of the contents is different.

  In other words, the cam surface shape that is integral with the operation lever and drives the discharge member etc., the movement stroke of the discharge member and each stem at the timing of transition to the operation mode with the operation mode setting operation is different from that of the operation lever itself. Also, the valve of each container body is opened substantially at the same time at the transition timing.

The new reference numbers (4d, 15-17) used in FIGS. 4-7 are as follows:
4d is a part of the discharge member 4, and an upper surface portion of a cylindrical circumferential surface with which a cam surface of a cam portion 17c described later contacts,
15 is a connecting member that fits into each of the annular concave portions 1a and 1a ′ of the container main bodies 1 and 1 ′ to integrate the container main bodies,
15a is formed on the outer peripheral surface of the connecting member intermittently, and is a tapered stepped locking portion for engaging and holding a cover body 16 described later,
15b is a guide standing portion for preventing the discharge member 4 and the like from being displaced forward by the action of the cam portion 17c accompanying the operation mode setting operation,
16 is engaged with the locking portion 15a of the connecting member 15 and the like. The front upper opening corresponding to the discharge member 4, the upper missing portion corresponding to the operation lever 17 described later, and a pair for protecting the operation member described later. Cover body (shoulder cover) with wall-like parts,
16a is a plurality of rib-like portions engaged with the connecting member 15,
16b is a part of the rib-shaped portion, and a stepped portion that comes into contact with the upper surface portion of the connecting member 15,
16c denotes a tapered stepped portion to be engaged and held by the engaging portion 15a of the connecting member 15,
16d is a bearing portion of an operation lever 17 (rotating shaft 17b) described later,
16e is a part of the cover body, and a rear upper surface portion that receives the operation mode lever 17 (see FIG. 6),
16f is a part of the cover body and a front upper surface portion for receiving a protection mode operation lever (see FIG. 7);
16g is an opening area for each of two inner sides of a cam portion 17c described later
17 is a rotation type operating lever integrated as a whole,
17a is an operation surface when the user performs a push-down operation,
Reference numeral 17b denotes a rotating shaft having both end portions supported by the bearing portion 16d of the cover body 16,
17c, four cam portions (cam plates) that contact the upper surface portion 4d of the discharge member 4 to drive the member to the operation mode position;
Respectively.

  Here, the connecting member 15, the cover body 16, and the operation lever 17 are made of plastic made of polypropylene, polyethylene, polyacetal, nylon, polybutylene terephthalate, or the like.

4 to 7, a basic feature of the content discharge mechanism is that a plurality of cam portions 17 c integrated with the operation lever push down the discharge member 4 and the stems 3 and 3 ′ by rotating the operation lever 17. In addition, the cam surface of the cam portion 17c is set to a mode in which the discharge member 4 is moved downward by a displacement amount larger than the movement amount (rotation amount) of the operation lever 17 at a predetermined stage of the pressing operation. It is that you are.
In particular, when the discharge member 4 is moved downward by a displacement larger than the amount of movement of the operation lever 17, two well-known valve operating portions (not shown) interlocked with the stems 3 and 3 ′ are fully opened. It becomes easy to match.

  As a result, when the user rotates the operation lever 17 in the stationary mode in the direction of the operation mode (clockwise in the drawing) to the predetermined stage, the stems 3 and 3 ′ of the respective containers are respectively well-known. The valve action portion (not shown) is moved down to a position where it is opened almost simultaneously.

  Therefore, the related mechanisms after the assembly such as the stems 3 and 3 ′, the discharge member 4 and the operation lever 17 are supposed to cause the height of the stems 3 and 3 ′ of each container body, the inclination of the discharge member, and the upper surface portion 4d of the discharge member. Even if there is a variation in the timing of contact between the valve body and the cam portion 17c and the subsequent movement speed of each stem, etc., the transition to the operation mode of the valve mechanism of each of the container main bodies 1 and 1 ' The timing is set almost simultaneously.

  The cam surface shape shown in the figure is a mode in which the discharge member 4 and the stems 3 and 3 'are hardly pushed down at the initial stage of rotation (clockwise) of the operation lever in the stationary mode, that is, in the case of FIGS. In the same way as the above, it is provided with a function for preventing fine operation at the initial stage of the rotation operation.

  In addition, the cam surface of the cam portion 17c may have a mode in which the stem is moved down at a stroke to a position where the valve action portions of the stems 3 and 3 ′ are opened substantially simultaneously in the initial stage of the rotation operation. .

  Here, since the operation lever 17 rotates about the rotation shaft 17b, even if the user depresses a portion away from the center of the operation lever or further depresses it in an oblique direction, the operation lever 17 is perpendicular to the discharge member 4. Directional force is applied.

As is apparent from FIG. 4, the setting positions of the four cam portions 17c on the rotation shaft 17b are symmetrical positions about the intermediate portions of the stems 3 and 3 ′, respectively.
Further, the two cam portions (the outer cam portion and the middle cam portion) on the left and right sides of the intermediate portion are provided at symmetrical positions with the stems 3 and 3 ′ as the centers.

  Therefore, an equal pressing force can be applied from the operation lever 17 to the two stems 3, 3 '(discharge member 4).

  When the valve action portions of the two stems 3 and 3 'are in the open state, the contents of the container main bodies 1 and 1' are respectively "stem internal passages" as in the case of the contents discharge mechanism of FIGS. -It flows into the common passage 4b of the discharge member 4 through the individual passages 4a, 4a '"of the discharge member 4, and is discharged from the injection port 4c to the external space.

  As shown in FIG. 6, in the final stage of the operation mode, the surface portion of the operation lever 17 opposite to the operation surface 17 a is in contact with the rear upper surface portion 16 e of the cover body 16.

  In order to prevent the operating lever 17 from being inadvertently pushed and shifted to the stationary mode, the operating lever is rotated counterclockwise from the stationary mode position as shown in FIG. What is necessary is just to set to the aspect by which the part of the surface 17a is hold | maintained at the front side upper surface part 16f of the cover body 16. FIG.

  In this protect mode, the cam surface of the cam portion 17c is separated from the upper surface portion 4d of the discharge member 4, and the operation member 17 cannot move at all even if it receives a downward pressing force.
