Description

  The present invention shuts off the content passage area near the discharge port from the upstream side by the valve member corresponding to the discharge port that automatically returns to the stationary mode upon completion of the content discharge operation, and discharges the remaining contents there. The present invention relates to a content release mechanism that is pushed out from an external space.

  In addition, a content discharge mechanism that sets the upstream content passage area of this shut-off partner to a closed space area in the stationary mode and prevents residual contents there from flowing out from the discharge port after returning to the stationary mode. About.

  By aggressively pushing out the residual contents in the passage area near the discharge opening to the external space area and setting the shut-off space area upstream of the passage area, after returning to the stationary mode, the external space from the discharge opening Residual contents can be prevented from dripping out into the area in the after-foaming state.

  In the present invention, the valve member corresponding to the above-described discharge port is urged to a stationary mode state by an elastic member and moved to an operation mode in a form against the elastic member at the time of content discharge operation, The valve member automatically returns to the stationary mode upon completion of the content discharge operation.

  Therefore, it is not necessary for the user to check whether the valve member for pushing out the residual content near the discharge port is in the stationary mode or the operation mode and to move the valve member.

  The content release mechanism of the present invention is used for aerosol type products and pump type products. For example, the present invention can be applied to the case of various contents described later in addition to a post-foaming agent, gel-like, cream-like, highly viscous liquid, and the like.

  In this specification, regarding the positional relationship between front, rear, left and right, the side of the horizontal hole 6g of the discharge port is described as “front”, and the side of the leaf spring 8e opposite thereto is described as “rear”. That is, the left side of FIGS. 1 to 3 is “front” and the right side is “rear”. The directions orthogonal to the front-rear direction are referred to as “left-right” and “horizontal”.

  Conventionally, after the content discharge operation is completed, the content passage area near the discharge port is shut off from the upstream side (stem outflow side) of the content passage area. There has been proposed a content discharge mechanism that pushes out into a region (see Patent Document 1). The numbers in parentheses in the following background art description indicate reference numbers used in Patent Document 1.

  When the residual content is pushed out in Patent Document 1, the user can operate the operation portion [23] of the central shaft [21] disposed in the content passage area by a new manual operation after the content discharge operation is completed. It is moved to the tip of the injection cylinder [6].

  In other words, in order to push the remaining contents in the content passage area near the discharge port from the discharge port to the external space area, the user is required to drive the central shaft [21] in a different direction after the content discharge operation. Manual operation must be performed by the dedicated operation unit [23].

JP 2011-162227 A

  Thus, in the case of the conventional content discharge mechanism that pushes out the residual content in the content passage area near the discharge port after the content discharge operation is completed, the user manually presses the extrusion member. It is moved in the extrusion direction by operation.

  Therefore, every time the user tries to push out the residual content to the outside space area, the user moves the pushing member (corresponding to the valve member of the present invention) toward the discharge port by his / her new manual operation. There was a problem that it was difficult to use and was inconvenient.

  Therefore, in the present invention, the valve member for extruding the residual content to the external space is urged to the position of the stationary mode by the elastic member, and this valve member resists the elastic member during the content discharge operation. It moves in a shape and elastically returns to the stationary mode upon completion of the content discharge operation.

  Thus, by automatically forcibly returning the valve member to the stationary mode at the end of the content discharge operation, the residual content in the content passage area shut off from the stem side near the discharge port, It is an object of the present invention to ensure the extruding operation of the valve member in the external space region.

  Further, it is possible to eliminate the necessity of the individual operation of the user for the pushing operation of the residual content near the discharge port to the external space area, and to make the user operation convenient in the content discharge mechanism corresponding to the pushing operation. For the purpose.

  In addition to this extrusion operation, the content passage area immediately upstream of the discharge port side portion to be extruded is set as a closed space area in accordance with the automatic return of the extrusion valve member to the stationary mode, and the residual contents in the stationary mode are set. The purpose is to reliably prevent the outflow from the discharge outlet.

  In addition, the elastic member for biasing the stationary mode of the extruding valve member is integrated with the valve member and the content discharge operation portion, and the management of a plurality of related parts of the content discharge operation and the residual content push-out operation, An object of the present invention is to simplify the assembling work as the contents discharge mechanism.

  Further, the free end portion of the elastic member that urges the push-out valve member to the stationary mode position is guided to the cover portion of the container body that contains the contents, so that the degree of freedom in arranging the elastic member is increased. The purpose is to plan.

The present invention solves the above problems by using the following content release mechanism.

  Here, the housing 3, the one-touch cap 6, the valve member 7 and the operation portion 8 are made of plastic made of, for example, polypropylene, polyethylene, polyacetal, nylon, polybutylene terephthalate or the like.

  The container body 1, the stem 4 and the coil spring 4c are made of, for example, metal and plastic, the mounting cup 2 is made of, for example, metal, and the stem gasket 5 is made of, for example, rubber or plastic. .

The basic features of the illustrated content release mechanism are:
(21) When the user slides down and pushes down the operation surface 8b in the stationary mode of FIG. 1 as shown in the direction A, the horizontal hole 6g as the discharge port and the vertical hole 6j on the stem outflow side Is transferred to the operation mode of FIG. 2 in which the stem hole 4b is set to the open state,
(22) With the end of the sliding / pressing operation of (21) above, as indicated by direction B, the stem 4 / button actuating portion 6c is moved upward by the elastic action of the coil spring 4c, and the leaf spring 8e The valve member 7 moves forward due to the elastic action of FIG. 2 → FIG. 3 → FIG.
(23) As shown in FIG. 3, in the initial stage of the automatic return of the valve member 7 forward from the operation mode of FIG. 2, the external space is opened through the horizontal hole 6g while being shut off from the vertical hole 6j. And a closed space area S2 from the shut-off vertical hole 6j and the valve member 7 to the closed stem hole 4b, respectively, are set.
(24) Residual contents in the sheath-like space area S1 are pushed out from the lateral hole 6g to the external space area at the front surface portion of the valve member 7 with the further forward movement of the valve member 7 following this initial stage,
(25) Further, the residual content in the closed space area S2 is retained in the closed space area in both the initial stage and the subsequent movement / rest mode of the valve member 7 and remains in the closed space area. The phenomenon that the thing flows out from the lateral hole 6g to the external space area does not occur.
And so on.

  In the stationary mode of FIG. 1, the stem hole 4b moved to the uppermost position by the elastic force of the coil spring 4c is blocked by the stem gasket 5, and corresponds to the valve member 7 moved to the foremost position by the elastic force of the leaf spring 8e. The volume of the sheath-like space area S1 is set to a minimum state.

  That is, when the upstream side is viewed from the side hole portion 6g of the contents discharge port to the external space, the so-called double valve of the valve member 7 and the stem hole portion 4b is closed between the housing 3 and this side valve. The space area immediately upstream of the hole (= sheath space area S1) is set to the minimum volume.

  In the stationary mode in such a setting state, the residual contents in the content passage space region (sheath-like space region S1 + closed space region S2) from the closed stem hole portion 4b to the horizontal hole portion 6g are transferred to the horizontal hole portion. It is possible to substantially suppress the occurrence of, for example, post-foaming from flowing into the external space region.

  The residual contents in the closed space area S2 remain accommodated therein, and do not flow out from the lateral hole 6g to the external space area.

The residual content of the sheath-like space area S1 can flow out to the external space area, but the amount is very small.
This is because, as shown in FIG. 3, the sheath-like space area S <b> 1 is reduced by the forward action of the valve member 7 when returning to the stationary mode after the end of the previous content discharge operation.

  When the user presses down the operation surface 8b in the stationary mode shown in FIG. 1 while sliding backward, the stem hole 4b is set in an open state, and the horizontal hole 6g and the vertical hole 6j of the button operating part 6c communicate with each other. Transition to operation mode.

  Here, along with the backward sliding operation of the operation surface 8b in the stationary mode, the leaf spring 8e has its free end side (rear side portion) guided to the inner peripheral surface of the rear upright portion 6k, and the U-shaped bottom side. Deforms against the self-elasticity of the part.

  Due to this deformation action, the drooping portion 8c, the rear cylindrical portion 8d, and the valve member 7 integrated therewith move rearward, and then the outer end portion of the skirt-like portion 7b spreads out to the vertical hole portion of the horizontal tubular portion 6e. It is located behind 6j.

  By the rearward movement of the skirt-like part 7b, the horizontal hole part 6g serving as an outlet to the external space and the vertical hole part 6j serving as an inlet to the horizontal cylindrical part 6e communicate with each other. That is, the valve-operated stem hole 4b communicates with the external space region discharge actuated lateral hole 6g.

  Further, as the operation surface 8b is pushed down, the button actuating portion 6c rotates around the thin portion 6d in the clockwise direction in the drawing to drive the stem 4 downward.

  As the stem 4 moves downward, the opening / closing relationship between the stem hole 4b and the stem gasket 5 whose outer end annular portion is clamped and fixed to the mounting cup 2 and the housing 3 shifts from the previous closed state to the open state. To do.

  With the communication between the horizontal hole portion 6g and the vertical hole portion 6j and the transition to the open state, the contents of the container body 1 are “container body 1−housing 3−stem hole portion 4b−stem passage portion 4a−vertical portion”. It is injected to the outside through a route of “hole 6j−front side internal space area of horizontal cylindrical portion 6h−horizontal hole 6g”. This path is indicated by the arrow in FIG.

  At this time, the skirt-like portion 7b that spreads rearward of the front valve member 7a is in close contact with the inner peripheral surface on the rear side of the vertical hole portion 6j of the horizontal cylindrical portion 6e in a sealed state. There is no such thing as leaking backward from the shaped part.

  When the user finishes the backward sliding / pressing operation to the operation surface 8b, the so-called movable unit consisting of the stem 4, the button operation part 6c, the valve member 7 and the operation part 8 is changed from the operation mode of FIG. Automatically return to static mode.

This automatic recovery operation
(31) The stem 4 moves upward based on the elastic force of the coil spring 4c,
(32) Based on the elastic force of the leaf spring 8e, the unitary body of the hanging portion 8c, the rear cylindrical portion 8d, the front valve member 7a, and the rear valve member 7d moves forward.
That is.

  Then, as shown in FIG. 3, the outer end portion of the skirt-like portion 7b that spreads afterward in the middle of the forward movement of the front valve member 7a of (32) passes through the vertical hole portion 6j of the horizontal tubular portion 6e. At the finished stage, the sheath-like space area S1 and the closed space area S2 immediately upstream thereof are set. The contents to be released remain in the sheath-like space region S1 and the closed space region S2, respectively.

  The remaining contents of the sheath-like space area S1 are pushed by the front part of the front valve member 7a (rearly spread skirt-like part 7b and front central sheath-like part 7c) that moves further forward, and the outside from the lateral hole part 6g. It flows into the space area.

  Due to the flow-out action of the residual contents of the sheath-like space area S1 to the external space area based on the forward movement of the front valve member 7a, the sheath in communication with the external space area is automatically returned to the stationary mode in FIG. The volume of the space area S1 is small, and of course there is little residual content.

  The closed space area S2 that is initially set together with the sheath-shaped space area S1 does not change in internal volume even when the front valve member 7a moves further forward, and the contents there remain in the external space area after returning to the stationary mode. The initial residual state is maintained without any leakage.

  As described above, the passage from the stem hole 4b to the horizontal hole 6g for discharging the contents is automatically returned to the front of the valve member 7 upon completion of the contents discharge operation by the user, thereby enabling communication with the external space region. The sheath space area S1 and the closed space area S2 immediately upstream thereof are divided into two.

  The residual contents in the sheath-like space area S1 in the initial state are positively discharged from the lateral hole 6g to the external space area by the movement of the valve member 7 to the stationary mode position, and the residual contents in the closed space area S2 The object is confined in a state shut off from the side hole 6g.

  Therefore, the residual contents in the passage portion connected to the horizontal hole portion 6g for discharging contents do not flow out from the horizontal hole portion, for example, in a post-foamed state.

The assembly procedure of the illustrated content release mechanism is, for example,
(41) The front cylindrical portion 7f is fitted to the front central sheath-like portion 7c so that the front valve member 7a and the rear valve member 7b are integrated into the valve member 7.
(42) The rear cylindrical portion 8d of the operating portion 8 is fitted to the rear central sheath portion 7g of the valve member 7 assembled in (41) above.
(43) With the button operating portion 6c lifted, the valve member 7 of the operating portion 8 assembled in (42) above is inserted into the horizontal tubular portion 6e from the rear.
(44) Return the button operating portion 6c to the original stationary mode position, and set the free end portion 8f of the leaf spring 8e to the lower side of the forward saddle-shaped portion 6m.
And so on.

Of course, the present invention is not limited to the illustrated embodiment, for example,
(51) The operation mode setting operation is not a rotation operation in the clockwise direction shown in the drawing centering on the button operation unit 6c and the thin portion 6d of the operation unit 8, but the vertical operation in which the button operation unit 6c is separated from the cap operation unit 6b. It is a push-down operation in a free form,
