Description

  The present invention relates to a cover cap rotation type content discharge mechanism for pump type products and aerosol type products.

  In particular, a sheath-like cover cap having a protection function and a content discharge operation function for a discharge operation member having a content passage portion and a content discharge port, and having an opening corresponding to the content discharge port, A rotating cover cap type content discharge mechanism that can be rotated between a lock reference position where contents cannot be discharged with respect to the container body and a lock release position where contents can be discharged while being attached to the discharge operation member. About.

  Here, the upper surface of the container body and the circumferential lower end portion of the cover cap corresponding thereto have, for example, substantially the same circumferential contour, and the cover cap is rotated in the circumferential direction from the lock reference position to the unlock position. A part of the lower end portion in the circumferential direction protrudes to the outside of the edge portion (such as an elliptical shape) by moving.

And
(11) At the lock reference position of the cover cap, due to the contact action between the upper surface of the container body and the lower end portion in the circumferential direction of the cover cap, the downward movement operation (content discharge operation) of the cover cap is prevented,
(12) At the unlocking position after the cover cap turning operation, the contact action of (11) does not occur, and the downward movement operation for releasing the contents of the cover cap is possible.

  In the present specification, the side of the content discharge port is referred to as “front”, and the side in the opposite direction is referred to as “rear”. That is, the left side of FIGS. 3 and 5 is “front” and the right side is “rear”.

  The vertical direction of the cover cap and the container main body is defined as “vertical direction”, and the direction orthogonal to both the front-rear direction and the vertical direction is defined as “lateral direction”. The front-rear direction substantially coincides with the major axis direction of the elliptical shape, and the lateral direction substantially coincides with the minor axis direction of the elliptical shape.

  Further, the circumferential rotation operation of the cover cap is a relative operation with respect to the container main body (release operation member), and the rotation is also performed when the user rotates the container main body while the cover cap is fixed. Included in dynamic operations.

  In a content discharge mechanism that shifts between a lock reference position (content discharge operation is impossible) and a lock release position (content discharge operation is possible) by rotating the cover cap in the circumferential direction with respect to the discharge operation member. It is desirable to simplify the mechanism part for setting and holding the cover cap at each of these positions, and the present invention meets such a demand.

  Conventionally, by rotating the cover cap in the circumferential direction of a discharge actuating member having a content discharge port, the cover cap is moved to its lock reference position (content discharge operation is impossible) and unlock position (content discharge operation is possible). ) Has been proposed (see, for example, Patent Document 1).

This content release mechanism is related to aerosol type products,
(21) A base [60] including a release actuating member (corresponding to the screw cap and mounting cap of the present invention) and an operation button [70] (this book attached to the base and capable of rotating in the circumferential direction) Corresponding to the cover cap of the invention)
(22) Each outer peripheral surface of the base [60] and the operation button [70] has substantially the same circular cross section,
(23) A lock reference position where the contents can not be released (pushing and tilting the action button down) by rotating the actuating button [70] in the circumferential direction with respect to the base [60], and a lock where the contents can be released. Is selectively set to the release position,
(24) As a configuration for individually specifying the lock reference position and the unlock position,
-The base [60] has a lock position stop [132] and an unlock stop [131],
The operation button [70] is provided with a button position stop [172] corresponding to the lock position stop [132] and a button position stop [171] corresponding to the lock release stop [131].

JP 2009-173350 A

  As described above, the operation button [70] (corresponding to the cover cap of the present invention) with respect to the conventional base [60] (corresponding to the screw cap and mounting cap of the present invention) is rotated in the circumferential direction. In the case of the content release mechanism set to the lock reference position where the content discharge operation is impossible and the lock release position where the content discharge operation is possible, the components for individually specifying the lock reference position and the lock release position are Each of the base and the activation button is formed.

  That is, as described in (24) above, the base [60] is formed with the lock position stop [132] and the lock release stop [131], and the operation button [70] is formed with the button position stop [172] and the button position. A stop [171] is formed.

  For this reason, the production process of the entire content release mechanism comprising these base [60] (corresponding to the screw cap and mounting cap of the present invention) and the operation button [70] (corresponding to the cover cap of the present invention) There was a problem that the production cost was increased.

  According to the present invention, the circumferential contour shape of the upper surface of the container main body and the circumferential lower end portion of the cover cap corresponding thereto is such that a part of the circumferential lower end portion is rotated by the rotation operation from the lock reference position to the unlocking position. If it is set so that it protrudes outside the upper surface of the container body, the container body itself is originally provided as a locking partner if the position setting part of the lock reference position and the unlocking position is formed in the protruding part of the cover cap. This is because the outer peripheral surface can be used.

  In other words, this is a rotating cover cap type content discharge mechanism that pays attention to the fact that it is not necessary to provide a locking counterpart of the position setting portion formed on the cover cap on the screw cap, the mounting cap or the like.

  The circular contour shape of the upper surface of the container main body and the lower end in the circumferential direction of the cover cap, which can be the object of the present invention, is various “non-circular” shapes such as “elliptical”, “polygonal”, and “heart-shaped”. It is.

  For example, the screw cap 5 of the pump unit is screwed to the cylindrical neck 1c of the container body 1, and then the cover cap 2 is connected to the outer slope portion 1f of the container body 1 and the button member 3 (semicircular wall 3b). ) In the state of the lock reference position, the entire pump-type product is assembled.

The basic features of the illustrated cover cap rotation type content discharge mechanism (pump operating mechanism)
(31) A cover cap 2 provided with a pressing operation surface 2b for operating the pump is attached to the side of the container body 1 so as to be rotatable without being pulled upward.
(32) The lock reference position of the cover cap 2 in which the entire lower end surface 2a of the cover cap 2 is in contact with the edge portion 1b of the container body 1 and the pressing operation surface 2b cannot be pushed down is set to the container body 1 The outer peripheral surface is held by the locking action of the lock reference setting surface 2f and the locking action of the long-diameter side surface portion 1g and the longitudinal protrusion 2j (see FIGS. 1, 3 and 5).
(33) By rotating the cover cap 2 held at the lock reference position 90 degrees with respect to the container body 1 in the A direction, the cover cap has a rectangular cut-out portion 2d with a short diameter of the container body 1. It is displaced to the unlocking position that crosses the directional part (see Fig. 6).
(34) When the user pushes down the pressing operation surface 2b of the cover cap 2 in the unlocked position, the button member 3 and the piston 7 integrated with the cover cap move downward while resisting the elastic force of the coil spring 9. To a known pump operating state (see FIG. 7),
That is.

  When the cover cap 2 held at the lock reference position in (33) is rotated about 90 degrees in the A direction with respect to the container body 1, the longitudinal side surface portion 1g of the container body and the length of the cover cap are Each locking portion with the directional protrusion 2j is elastically deformed.

  Due to this elastic deformation action, the longitudinal projecting portion 2j of the cover cap 2 gets over the side surface portion 1g in the major axis direction of the container body 1.

  The vertical position of the cover cap 2 in the middle of the turning operation in the A direction is the contact action between the lower end surface 2 a and the container main body upper surface 1 a, and the circumference of the ring-shaped protruding portion 2 m of the cover cap 2 and the button member 3. It is held by the locking action with the directional protrusion 3c (see FIGS. 3 and 4).

  At the unlock position, the unlock setting surface 2g of the cover cap 2 (vertical piece 2e) is in contact with the outer peripheral surface of the container body 1 (= the outer peripheral surface portion different from the lock reference position). Therefore, the cover cap 2 at the unlock position does not further rotate in the A direction (see FIGS. 6 and 7).

  The operation of turning the cover cap 2 in the A direction is guided to each of the semicircular wall portions 3 b of the button member 3.

  In the case of the container body 1 and the cover cap 2 shown in the figure, the longitudinal direction piece 2e is the center of the cylindrical neck 1c (== the straight line in the front-rear direction of the container body upper surface 1a in the virtual plane state of the lock reference position (= The button member 3 and the screw cap 5 are located on a line inclined approximately 45 degrees in the A direction as viewed from the center.

  Further, the longitudinal piece 2e at the unlocked position obtained by rotating the cover cap 2 at the lock reference position by 90 degrees in the A direction is the center of the cylindrical neck 1c and the like with respect to the straight line in the front-rear direction of the container main body upper surface 1a. It is located on a line inclined approximately 45 degrees in the reverse A direction.

  That is, when the inclination angle in the A direction is α, the rotation operation angle in the A direction from the lock reference position to the unlock position of the cover cap 2 is set to approximately “180-2α” degrees.

  The pump operation process (34) at the time of the pressing operation of the pressing operation surface 2b of the cover cap 2 is roughly as follows.

That is, as the piston 7 moves downward,
(41) The volume of the cylinder internal space between the discharge valve member 10 and the ball valve 8 inside the cylinder 6 decreases, and the pressure of the contents there increases,
(42) Due to this pressure increase, the valve action portion between the piston 7 and the discharge valve member 10 changes from the previous closed state to the open state,
(43) The contents stored in the internal space area of (41) are moved from the open valve action part of (42) to “the lateral hole part 7a—the content passage part 7b, 3a—the lateral direction of the button member 3”. It discharges | emits to an external space area through the well-known clearance gap part-content discharge | emission port 4a of the cylindrical part and the nozzle 4 around it.

  Even if the user tries to shift to a rotation operation (rotation operation in the direction opposite to the A direction) to inadvertently return the cover cap 2 to the original position in the downward movement state of the piston 7, the cover Out of the front and rear direction end portions (vertical edge portions) of the rectangular notch-shaped portion 2d of the cap, the end portion where the vertical piece portion 2e is not formed hits the outer peripheral surface of the container body 1, and this A direction is There is no mistaken operation in the reverse direction.

  Then, when the pressing operation of the pressing operation surface 2 b of the cover cap 2 is finished, the piston 7, the button member 3 and the cover cap 2 are integrated and returned upward by the elastic force of the coil spring 9.

  With this known return operation, the valve action portion between the piston 7 and the discharge valve member 10 shifts to a closed state, and the volume of the cylinder internal space between the discharge valve member and the ball valve 8 becomes larger. Increasing and the content pressure there is less than that of the container body 1.

  Therefore, the ball valve 8 is opened and the contents of the container body 1 flow into the cylinder internal space through the dip tube 12. This inflow content is the next release target.

  In order to compensate for the decrease in the internal pressure of the container main body 1 due to the inflow of contents into the cylinder internal space, the outside air flows into the container main body through a well-known path (not shown).

  Then, by rotating the cover cap 2 returned in the upward direction in the direction opposite to the A direction, the positional relationship between the cover cap and the container body 1 returns to the initial state of FIG.

Of course, the present invention is not limited to the illustrated contents.
(51) Instead of the push-down and up-and-down type button member 3, tilt type and tilt type button members are used.
(52) The protruding portion 5b of the screw cap 5 is omitted, and the screw coupling state (rotation state) of the screw cap with respect to the cylindrical neck portion 1c of the container body 1 is changed to the content discharge port of the button member 3 (nozzle 4). 4a is set to a forward-facing position,
(53) When the container main body upper surface 1a is not a horizontal flat surface having the same height as the edge portion 1b as shown in the drawing, but is formed of a hollow surface portion having a shape lower than the edge portion 1b,
Instead of the rectangular cutout portion 2d of the cover cap 2, the cover cap is opposed to the edge portion that can be said to be an annular upright wall when viewed from the recessed surface portion when the contents can be released (see FIG. 6). Only the lower end side portion (≈ each rising portion on both sides in the front-rear direction of the rectangular cutout portion) is formed with vertical (in the illustrated case, four) cutout portions into which the edge portion enters.
