Abstract

PROBLEM TO BE SOLVED: To make the discharge state of contents to be discharged by slanting an operation member accord to the discharge state before the operation member being slanted which is assumed by an average user. SOLUTION: A discharge member 20 with which a discharge opening 20b is formed is engaged with a cover body 10 which is different from the operation member 30 which is slanted by operating a trigger lever 30a. The fixed discharge member 20 is made to communicate with the operating operation member 30 by a flexible pipe 40 to mediate between the two members. When the trigger lever 30a is operated, the operation member 30 is rotated around the fulcrum of a rotary shaft 30f, and a stem 50 is pressed to discharge the contents. Since the position of the discharge opening 20b is not changed from that before the operation, the contents are discharged in the direction which is expected by a user. When the operation of the trigger lever 30a is stopped, the stem 50 is brought up by the bias of a restoring spring, and the operation member 30 is also restored to the state before the operation. During the operation of the trigger lever 30a, since the flexible pipe 40 is deformed, the operation member 30 is operated smoothly.

2. Description of the Related Art FIG. 3 is an explanatory view showing a conventional contents discharge operation mechanism for discharging contents by tilting operation of an operation member, 60 is a contents discharge operation mechanism, 61 is an operation member, 61a.
Is a trigger lever, 61b is a rotating shaft, 61c is a vertical passage for release, 61d is a horizontal passage for release, 62 is a cover body, 62a is a substrate for mounting the trigger lever 61a, 62b is an inner protruding portion, and 63 is a release passage. An outlet member, 63a is a discharge port, 64 is a stem, 65 is a mountain cap, and 66 is a container.

[0003] As shown in FIG.
In this case, when the trigger lever 61a is pulled, the operation member 61 is rotated and tilted forward, and the stem 64 is pressed by this forward tilting operation to open a content discharge valve (not shown).

[0004] The discharge port member 63 is fitted and integrated with the operating member 61, and when the trigger lever 61a is operated, the discharge port member is released.
63 a is interlocked with the operation of the operation member 61.

[0005] The contents release operation mechanism 60 includes a cover body 62.
The inner protruding portion 62b is engaged with the mountain cap 65 and attached to the container 66.

In the non-use mode, the trigger lever 61a is in the illustrated state, and the stem 64 is a return spring (not shown).
As a result, the contents discharge valve (not shown) is closed, and the contents are not discharged to the outside.

In the use mode, when the user holds the container 66 with one hand and pulls the trigger lever 61a toward the user, the operation member 61 is rotated.
It rotates counterclockwise around 61b. The operating member 61 leans forward, and the forward leaning operation pushes the stem 64 downward against the return spring.

As a result, the valve for discharging the contents is opened and the container is opened.
The contents in 66 pass through the stem 64, the vertical passage 61c for discharge, and the horizontal passage 61d for discharge, and are discharged to the outside from the discharge port 63a.

When the trigger lever 61a is released, the valve for discharging the contents is closed by the action of the above-mentioned return spring, and the stem 64 is moved upward. This return operation also returns the trigger lever 61a to the state shown in the figure.

[0010]

As described above, since the discharge port member of the conventional contents discharge operation mechanism is provided on the operating member which is tilted by operating the trigger lever, the discharge port is provided when the user is not in use. The content is released in a direction different from the direction in which the content is directed.For example, there is a problem that the user wants to release the content in a horizontal direction, but the content is released downward. Was.

Therefore, in the present invention, the output unit of the contents is
Apart from the operation member, it is integrated with the cover body so that the position of the discharge port when the operation member is tilted does not change from the position before tilting, and the actual discharge start position and discharge direction of the contents are set before operation. The purpose is to match the average assumption of the user.

[0012]

Means for Solving the Problems In order to achieve this,
In the present invention, a content release mechanism having the following configuration is used. (1) A stem (for example, a stem 50 to be described later) is tilted by an operation member (for example, an operating member 30 or a trigger lever 30a to be described later) attached to a cover (for example, a cover 10 to be described later) of a container (for example, a container 52 to be described later). ) To release the contents of the container from an output unit (e.g., a release member 20 described later) into an external space, in which the output unit is connected to the cover body separately from the operation member. The output portion and the stem are connected by a flexible pipe (for example, a flexible pipe 40 described later), and the position of the discharge port of the output portion when the operating member is tilted is tilted. Match the position before operation. (2) In the above (1), the output portion is integrally formed with the cover body. (3) In the above (1), the output section is a separate member from the cover body.

According to the present invention, as in (1), (2) and (3), the output section of the contents is provided separately from the operation member.
Since it is integrated with the cover body, the position of the discharge port does not change due to the tilting operation of the operating member, for example, does not move up and down or tilts. Therefore, the contents are discharged as it is in the direction predicted by the user before the tilting operation.

Further, at the time of the tilting operation, the flexible pipe between the discharge port of the output unit integrated with the cover body and the stem pressed by the tilting of the operating member is deformed to mediate between them. The member works smoothly. Due to this deformation, the operation member also operates smoothly when returning.

Further, as described in (2) above, the number of parts is reduced by integrally molding the output portion with the cover body.

A hole for mounting the operation member 30, 10c is a reinforcing plate of the cover body 10 or the substrate 10a, 10d is a fixing portion of a discharge member described later, 10e is an opening, and 10f is an inner side engaged with a mountain cap 51 described later. Projection, 20 is a cylindrical discharge member, 20a is a discharge passage, 20b is a discharge port, 30 is an operation member, 30a is a trigger lever, 30b is a passage passage, 30c
Is the lower part of the passage, and 30d is the hole 10b of the cover body 10.
30e is a tapered surface, 30f is a rotating shaft on which the operating member 30 rotates with respect to the cover body 10, 40 is a flexible pipe, 40a is an upstream end, 40b is a downstream end, 50 indicates a stem, 51 indicates a mountain cap, and 52 indicates a container.

As shown in FIGS. 1 and 2, the contents discharging operation mechanism 1 includes: a cover body 10; a discharging member 20 fixed to the cover body 10; and a rotatable attachment to the cover body 10. The operating member 30 includes a flexible pipe 40 for connecting the passages of the discharging member 20 and the operating member 30.

The release member 20 is fitted into the release member fixing portion 10d of the cover body 10 to be integrated with the cover body 10 and does not interlock with the operation member 30.

On the other hand, the operating member 30 has a passage 30b
The lower portion 30c is fitted to the stem 50, and the projection 30d is engaged with the hole 10b formed in the substrate 10a of the cover body 10 to rotate the rotating shaft.
It is rotatable with respect to the cover body 10 around 30f as a fulcrum.

The upstream end 40a of the flexible pipe 40 is fitted into the passage 30b of the operating member 30,
The downstream end 40b is fitted in the discharge passage 20a of the discharge member 20, and connects the two passages.

The flexible pipe 40 is an operating member.
Any material or shape having a certain degree of flexibility and elasticity that can be deformed by the operation of 30 may be used.
, EVA, high-density PE, or the like. Further, for example, it may be formed in a bellows shape or may be made of an elastomer or the like.

The procedure for assembling the contents discharge operation mechanism 1 is, for example, as follows. The upstream end 40a of the flexible pipe 40 is
In the passage 30b. The operating member 30 integrated with the flexible pipe 40 is put into the cover body 10 through the opening 10e of the cover body 10, and the tapered surface 30e is inserted into the hole 10b and pushed until the protrusion 30d gets over the hole 10b. . Using a jig or the like, the downstream end of the flexible pipe 40
The cover 40b is exposed from the discharge member fixing portion 10d of the cover body 10. The discharge member 20 is attached to the downstream end 40b of the flexible pipe 40.
And the release member 20 is fitted to the release member fixing portion 10d of the cover body 10.

Since the operation member 30 has the tapered surface 30e, it can be easily inserted into the hole 10b of the cover body 10. Further, once the convex portion 30d of the operation member 30 gets over the hole 10b of the cover body 10, it is caught by the hole 10b, and the operation member 30 does not come off the cover body 10.

The substrate 10a in which the hole 10b is formed is strong because it is also supported by the reinforcing plate 10c, and does not break even if a force is applied when the operating member 30a is inserted.

The contents discharging operation mechanism 1 includes a cover body.
When the inner projecting portion 10f of 10 is fitted to the mountain cap 51, it is attached to the container 52. Also, after the inner protrusion 10f of the cover body 10 is first fitted to the mountain cap 51,
The contents discharge operation mechanism 1 may be assembled.

As shown in FIG. 1, in a non-use mode in which the trigger lever 30a is not operated, the stem 50 is moved upward by the urging of a return spring (not shown), and a valve for discharging contents (not shown). ) Is closed so that the contents are not released to the outside.

As shown in FIG. 2, in the use mode in which the trigger lever 30a is pulled toward the user, the operating member 30 is turned on the rotating shaft 30f.
Is pivoted counterclockwise around the fulcrum to tilt forward, and presses the stem 50 against the return spring. Then, the contents discharge valve is opened, and the contents are discharged to the outside through the stem 50, the passage 30b, the flexible pipe 40, the discharge passage 20a, and the discharge port 20b.

At this time, since the flexible pipe 40 is deformed by its flexibility and elasticity, the operating member 30 smoothly leans forward and presses the stem 50.

Further, as described above, since the discharge member 20 is fixed to the cover body 10 separate from the operation member 30, it does not interlock with the operation of the operation member 30. Therefore, there is no change such that the outlet 20b moves up and down or tilts, and the contents are discharged in the same direction as the direction of the outlet 20b in the non-use mode.

When the operation of the trigger lever 30a is stopped, the stem 50 is released from the pressing of the operation member 30, so that the stem 50 is moved upward by the bias of the return spring, and the operation member 30 is in the non-use mode (see FIG. 1). ). Also at this time, since the flexible pipe 40 is deformed by its flexibility and elasticity, the operation member 30 can smoothly return to the non-use mode position.

The discharging member 20 may be formed integrally with the cover body 10. In this case, first, the flexible pipe
40 is inserted into the cover body 10 through the opening 10e of the cover body 10, the downstream end 40b is fitted into the discharge passage 20a, and then the operation member 30 is attached to the cover body 10 as described above. The contents discharge operation mechanism 1 is assembled by fitting the upstream end 40a of the pipe 40 into the passage 30b of the operation member 30.

In order to ensure that the discharge member 20 is fitted to the discharge member fixing portion 10d of the cover body 10, a protrusion or a rib is formed on one of the outer peripheral surface of the discharge member 20 and the inner peripheral surface of the discharge member fixing portion 10d. And the other may be provided with a concave portion corresponding to the projection or the like.

Further, the flexible pipe 40 and the discharge member
20, the outer peripheral surface of the upstream end 40a and the outer peripheral surface of the downstream end 40b of the flexible pipe 40, the discharge passage 20a of the discharge member 20, A projection, an annular rib, or the like may be provided in the passage 30b of the 30.

Further, the flexible pipe 40 is directly connected to the stem 50, and the contents are directly connected to the flexible pipe 40 from the stem 50.
You may make it flow into 40.

Further, a contents discharge operation mechanism using a push button type or tilt type operation member instead of the rotation type trigger lever 30a may be used. Also at this time, the discharge port member 20 is integrated with the cover body 10 separately from the operation member 30,
The outlet member 20 and the operation member 30 communicate with each other via a flexible pipe 40.

[0037]

According to the present invention, the output portion of the contents is integrated with the cover body separately from the operation member.
The contents can be discharged in the same direction from the same position as when the user turned the contents discharge operation mechanism before the tilting operation without changing the position of the discharge port by the tilting operation of the operation member.

Further, since the output portion of the contents integrated with the cover body and the stem operated by the operating member are communicated by a flexible pipe, the flexible pipe is deformed when operating the operating member, and mediates between the two. , The operation member can be operated smoothly.

Furthermore, the number of parts can be reduced by integrally molding the output section with the cover body.
