Description

  The present invention provides an aerosol operation of short stem movement and a stem length movement based on an upstream valve and a downstream valve in a gas pressure reduced state, in accordance with a movement length of a stem with respect to a container body containing contents and a jetting gas thereof. And a pumping operation.

  In particular, a moving body that moves between a stationary mode position (aerosol operation mode position) and each position of the pump operation mode is provided in a housing that constitutes a space area for passing and storing contents inside the container body, A stem is accommodated and held in this movable body in a form capable of relative movement.

  The stem is biased toward the stationary mode position by the strong elastic force, and the moving body is biased toward the stationary mode position by the weak elastic force.

  The moving body is urged to the stationary mode position by the internal pressure in the normal aerosol operation mode in which the housing internal pressure is large, and is held by a weak elastic force when the housing internal pressure decreases. The internal pressure of the housing in the aerosol operation mode can be said to be the internal pressure of the container.

  That is, the space region between the downstream valve of the stem and the upstream valve of the housing becomes a pump operation target region accompanying the movement of the moving body against the weak elastic force. Is closed, and the contents of this space area are discharged from the downstream valve in the open state to the external space area.

  When the internal pressure of the housing is reduced due to misuse or the like, a shift is made from the aerosol operation to the pump operation, so that substantially all of the contents contained in the container body are discharged to the external space.

  Note that misuse is, for example, an aerosol operation in which the suction side end of a dip tube 9 described below is separated from the contents to be sucked, such as when the aerosol operation is performed with the container body upside down. This is a usage method in which only the propellant of the gas phase component is released into the external space, causing a decrease in the internal pressure of the container body and making it difficult to release the remaining contents.

  In particular, in the case of products using compressed gas as a propellant, the propellant which evaporates to a release pressure is not mixed with the liquid phase contents, so that when the propellant of the gas phase component decreases, the fuel is injected. There is nothing to compensate for the pressure and the drop is remarkable. For this reason, the remaining stored contents cannot be discharged, and even if discharge is possible, problems such as dripping due to a decrease in jetting force and coarsening of spray particles are likely to occur.

  Conventionally, a short-moving aerosol operation based on an injection gas and a long-moving pump operation based on an upstream valve and a downstream valve after the pressure of the injection gas are individually executed according to the movement of the discharge operation unit and the stem. A possible content release mechanism has already been proposed (see US Pat.

JP-A-2014-91527

  The space inside the housing to be pumped by the contents discharge mechanism is between the downstream valve on the stem side and the upstream valve in the housing, and its volume is limited by the shape and size of the downstream valve. There was a problem.

  In the present invention, as a component for setting the internal space area of the housing to be operated by the pump, a moving body movable between the stationary mode position and the pump operation mode position and housing and holding the stem and the stem-side downstream valve is used. , Provided inside the housing.

  By disposing this moving body, the space inside the housing to be operated with the pump is set in an arbitrary manner independent of the downstream valve on the stem side, so that the upstream valve and the downstream valve after the pressure of the injection gas decreases. The purpose is to diversify and assure the pump operation of stem length movement based on.

  Further, the aerosol operation of the stem short movement based on the injection gas and the pump operation of the stem length movement based on the upstream valve and the downstream valve after the pressure of the injection gas is reduced can be individually executed as a content discharging mechanism. The purpose is to increase the convenience of.

Are respectively shown.

  Among the above components, the stem 2, the stem accommodating portion 3, the sealing portion 4, the housing 6, and the dip tube 9 are made of plastic, and are made of, for example, polypropylene, polyethylene, polyacetal, nylon, polybutylene terephthalate, or the like.

  The container body 1, the downstream coil spring 5d, the upstream coil spring 6e, the annular cup 7, and the ball valve 8 are made of plastic or metal.

  The stem rubber 5a is made of rubber, and the annular packing 7d is made of rubber or plastic. Here, a plastic stem seal member may be used instead of the rubber stem rubber 5a.

  The upward elastic force of each of the downstream coil spring 5d and the upstream coil spring 6e is set smaller in the upstream coil spring 6e.

  When the stem 2 is moved downward under the so-called virtual setting of the propellant “none” in the content discharging mechanism of FIG. 1, only the upstream coil spring 6 e having a small elastic force is contracted at least in the initial stage, and the stem 2 and the movement are reduced. The body 5 moves downward in the stationary mode as a whole.

  Then, with this downward movement, the volume of the upstream space area S1 between the moving body 5 and the housing 6 decreases, and the internal pressure there increases.

  As the internal pressure increases, the moving body 5 receives an upward force different from that of the upstream coil spring 6e, whereby the moving body 5 does not move down, but only the stem 2 moves down, and the moving body 5 moves downstream. The hole 2b is released from the closed state with the stem rubber 5a to the open state.

  With the transition of the downstream hole 2b to the open state, the discharge path f2 in the pump operation mode in FIG. 3 is set.

  The description of the related operations of the stem 2, the moving body 5, the downstream side coil spring 5d, the upstream side coil spring 6e, the upstream side space S1 and the like is based on the basic basic configuration of the pump operation mode of the illustrated content discharging mechanism. I can say.

  In the case of the aerosol operation mode in which the injection gas pressure is sufficiently large, the moving body 5 receives the upward force in the figure due to the large internal pressure (injection gas pressure) in the upstream space S1 and moves to the stationary mode position. Will be retained.

  That is, the moving body 5 is maintained in the stationary mode position in FIG. 1 and is set to a well-known aerosol operating state in which the stem 2 moves down with respect to the stem accommodating movable section 3 which is a component thereof.

In the stationary mode of FIG.
(11) Due to the elastic action of the upstream coil spring 6e and the internal pressure action of the upstream space area S1, the moving body 5 comes into contact with the upward annular step 4d and the annular bottom face 7b of the annular cup 7 at the uppermost position. Set to the hold state,
(12) By the elastic action of the downstream coil spring 5d and the internal pressure action of the downstream space area S2, the stem 2 is set in the contact position between the downstream hole 2b and the stem rubber 5a at the uppermost position. ,
(13) The ball valve 8 is in close contact with the inward annular tapered portion 6d of the housing 6 due to its own weight or the like.

In the aerosol operation mode in FIG. 2 in which the stem 2 moves down while resisting the elastic force of the downstream coil spring 5d in response to the contents discharging operation, as described above,
(21) The moving body 5 which is subjected to the elastic action of the upstream coil spring 6e and the internal pressure action of the upstream space area S1 upward is held in the stationary mode position,
(22) The internal passage area 2a of the stem 2 leading to the external space area and the downstream space area S2 of the stem accommodating movable section 3 communicate with each other through the open downstream hole section 2b,
(23) With the communication between the outer space area and the downstream space area S2, the ball valve 8 receives the internal pressure from the passage area side of the dip tube 9 and moves upward due to the total internal pressure.
(24) The upward movement of the ball valve 8 establishes the release path f1 in the aerosol operation mode.

  The discharge path f1 is defined as “a dip tube 9-a central opening area set by an inwardly-facing annular tapered part 6d-a groove-shaped part set between adjacent L-shaped rib-shaped parts 6c-an upstream space area S1-upstream” The side hole 3c-the downstream space S2-the downstream hole 2b-the internal passage area 2a of the stem 2 ".

  The moving body 5 does not shift downward in the aerosol operation mode because the moving body 5 is pushed up by a sufficiently large internal pressure action in the upstream space S1.

According to the verification of the illustrated content discharging mechanism, the aerosol operation mode of FIG. 2 in which the moving body 5 is held at the stationary mode position can be set because the internal pressure in the upstream space S1 is 1 kgf / cm ^2. ８8 kgf / cm ² .

In the verification state, assuming that the diameter of the upstream space area S1 is 15 mm, an upward force equivalent to 1.76 kgf is applied to the moving body 5 at an internal pressure of 1 kgf / cm ² . Here, the downstream coil spring 5d used had an elastic force of 0.7 kgf, and the upstream coil spring 6e used had an elastic force of 0.4 kgf. When the internal pressure of the upstream side space S1 is 1 kgf / cm ² , the upward biasing force received by the moving body 5 is 2.18 kgf (= 1.76 kgf + 0.4 kgf), which is the maximum pushing force of the stem 2 in the aerosol operation mode. It slightly exceeds a certain approx. 2kgf.

Here, when the internal pressure of the container body 1 (upstream space area S1) becomes 1 kgf / cm ² or less due to misuse of the discharging mechanism or accumulation of the contents discharging operation, the moving body pushing force of the internal pressure is sufficiently reduced. Further downward movement of the stem 2 in the aerosol operation mode becomes possible.

  That is, the stroke of the well-known contents discharge operation member (not shown) from the set position of the aerosol operation mode in FIG. 2 to the set position of the pump operation mode in FIG. 3 is possible.

  The contents discharge mechanism in the pump operation mode based on this stroke in FIG. 3 includes a downstream valve (discharge valve) of the downstream side hole 2b and the stem rubber 5a, and an upstream valve (the upstream valve of the inward annular tapered portion 6d and the ball valve 8). It operates similarly to a pump mechanism with a suction valve).

That is,
(31) When the internal pressure of the container body 1 (upstream space S1), which is the source of the push-up force, is reduced, the moving body 5 held by the upstream coil spring 6e having the weak elastic force has the stem 2 Moves down in a way that links with
(32) Due to this downward movement, the volume of the upstream space area S1 decreases and the internal pressure there increases,
(33) With the increase in the internal pressure, the ball valve 8 is pushed down to set the upstream valve to "closed", and the downward movement of the moving body 5 is braked, so that only the stem 2 moves downward.
(34) The downward movement of only the stem 2 ensures that the downstream valve is opened,
(35) The contents of the upstream space area S1 and the downstream space area S2 of increasing internal pressure are discharged from the internal passage area 2a of the stem 2 to the external space area via the downstream valve.

  The discharge path f2 at this time is "upstream space S1-upstream hole 3c-downstream space S2-downstream hole 2b-internal passage area 2a of stem 2".

  When the contents discharging operation such as the pressing operation of the push-down button (not shown) is completed, the contents discharging mechanism of the aerosol operation mode of FIG. 2 and the pump operation mode of FIG. The mode returns to the stationary mode in FIG. 1 by the elastic force of 6e.

  When the setting operation of the aerosol operation mode in FIG. 2 is completed, the stem 2 returns to its initial position by the elastic action of the downstream coil spring 5d.

  When the operation of setting the pump operation mode in FIG. 3 is completed, the stem 2 returns to its initial position by the elastic action of the downstream coil spring 5d, and the moving body 5 moves to its initial position by the elastic action of the upstream coil spring 6e. Return to.

When the stem 2 and the moving body 5 move upward to return to the initial position (stationary mode) with the release of the pump operation setting operation,
(41) The volume of each of the upstream space area S1 and the downstream space area S2 increases, and the internal pressure there decreases from that of the internal space area of the container body 1,
(42) With the decrease of the internal pressure, the ball valve 8 is separated from the inward annular tapered portion 6d and set to the upstream valve (suction valve) open state,
(43) The contents of the container body 1 flow into the upstream space area S1 and the downstream space area S2 via the dip tube 9,
(44) With the inflow of the contents, the internal pressures of the upstream space area S1 and the downstream space area S2 increase, and the total of the lower housing internal pressure and the dead weight acting on the ball valve 8 is substantially equal to the ball valve 8 The upstream valve closes when the pressure becomes larger than the internal pressure of the container body in the upward direction acting on
(45) By the closing action of the upstream valve, the contents discharge mechanism shifts to the stationary mode of FIG.

  Note that the contents that have flowed into the upstream space area S1 and the downstream space area S2 in (43) above are the discharge objects in the next pump operation.

  In the pump operation mode of FIG. 3, the depressurized state of the container main body internal space area due to the discharge of the contents stored in the container main body 1 to the external space area is the supply of the external air to the container main body 1 from the external air inflow hole 6f. To recover.

  The illustrated content discharging mechanism includes a short-moving aerosol operation based on the injection gas and an upstream valve (ball valve) and a downstream valve after the pressure of the injection gas is reduced due to a difference in stem movement length accompanying the content discharging operation. And long-running pump operation based on a valve.

Of course, the present invention is not limited to the above embodiments, for example,
(51) As the operation unit for driving the stem 2, various types of operation units such as a push-down button and a trigger lever are used.
(52) Instead of the stem rubber 5a, a valve member that moves in its entirety, for example, using a valve member disclosed in the above patent document,
(53) Instead of the upper O-ring 5b and the lower O-ring 5c, a sealing member formed by resin molding is used.
(54) The upper O-ring 5b and the lower O-ring 5c are integrated into a sealing member.
