  In this prior art, the contents stored in the cartridge which is the refill container portion are operated by a valve function portion provided on the main body side by the operation force from the cartridge side, thereby discharging the contents. Thus, the configuration on the cartridge side can be simplified.

  However, in the above-described prior art, the discharge passage for the contents is formed on the main body side, and the opening / closing valve is provided in the middle of the discharge passage, so that the contents always remain in the discharge passage. For this reason, there has been a problem that it becomes unsanitary due to clogging of the discharge path or deterioration of the remaining contents.

  In addition, when separating the used cartridge from the main body side, it is necessary to separate the main body side connecting member from the cartridge-side sealing portion separately from the screwing of the cartridge itself to the main body side. There is a problem that the processing is troublesome and the connecting member on the main body side is a main component of the valve function part, which may damage the valve function part.

  Therefore, the present invention was devised to solve the above-described problems in the prior art, and the liquid discharge of the liquid contents directly from the refill container portion stored therein is a technical problem, and thus stable discharge. The purpose is to obtain operation, hygienic use conditions, and safe attachment / detachment operation of the refill container part.

  The main structure of the liquid content discharge container of the present invention is a bottomed cylindrical piston having a discharge opening opened and closed at the upper end and for extruding the content from the discharge opening into a storage cylinder for storing the liquid content. A refill container part with a pull-down piece engaged and assembled to the lower end of this piston, and a lower end of the main body cylinder to which the lower end part of this refill container part is detachably attached The rotating knob provided is assembled so that it can rotate, and is screwed onto the spiral rod of this rotating knob. It is comprised from the raising functional part which provided the raising cylinder which makes a raising force act.

  The raising cylinder of the lifting function unit is moved over and locked to the lowering piece of the refill container part from above, and the locking of the lowering piece and the raising cylinder is made upward with respect to the spiral bar of the lowering piece. It is supposed to be released at the end.

  Since the refill container part that contains the contents has the piston positioned at the lower end part of the storage cylinder, when this refill container part is assembled to the upper end part of the main body cylinder of the lifting function part, the upper end surface of the lifting cylinder part Is opposed to the lower end surface of the piston, and the upper end portion of the lifting cylinder climbs over and is locked to the pulling piece from above.

  From this state, when the discharge port of the refill container part is opened and the turning knob of the lifting function part is turned to lift the lifting cylinder, the lifting cylinder pushes up the piston of the refill container part. From the inside of the refill container, a desired amount of contents are discharged from the discharge port for use.

    When the piston of the refill container part reaches the ascending limit position and the contents have been used up, the refill container part is removed from the lifting function part, and the refill container part is removed from the lifting function part. With the pulling piece raised, the storage cylinder of the refill container part is detached from the main cylinder of the raising function part at this position and either lifted up as it is or achieved by rotating the rotary knob in reverse. This is achieved by lowering the raising cylinder together with the lowering piece to the lower limit position.

  If the removal of the refill container part from the raising function part is achieved, the turning knob is turned in the reverse direction to lower the raising cylinder to the lower limit position, and the remaining lowering piece and the raising cylinder Is released, and the lowering piece is separated, and the lifting function portion side is set in a standby state in which a new refill container portion can be assembled.

  In addition to the above-described main configuration, another configuration of the present invention includes a pull-down piece body, a rod-shaped leg piece suspended from the bottom wall bottom center of the bottomed short cylindrical locking cylinder piece, The cylinder piece is inserted into the engagement cylinder piece suspended from the piston and joined by undercut, and the locking protrusion provided at the upper end of the inner peripheral surface of the lifting cylinder is attached to the locking strip provided around the leg piece. In this configuration, the vehicle is overridden and locked from above.

  In the case where the lowering piece is composed of a locking cylinder piece and a leg piece having a locking strip, a portion with a locking assembly for the piston of the lowering piece, and a portion with a locking assembly for the lifting cylinder Can be formed separately, whereby the locking force of both can be set separately.

  In addition to the main configuration described above, another configuration of the present invention is such that a bottom cap is detachably assembled to the lower end opening of the storage cylinder of the refill container.

  In the case where the bottom cap is assembled to the refill container part, the lower end opening of the storage cylinder is closed with the bottom cap, so the lowering piece which is a functional part of the refill container part is sealed and stored in the storage cylinder. can do.

Since the present invention has the above-described configuration, the following effects can be obtained.
Since the liquid content discharge container of the present invention discharges the content directly from the refill container portion containing the content, occurrence of inconvenience such as clogging of the content discharge passage or residual adhesion of the content Therefore, it is possible to always obtain a good discharge operation and a hygienic use situation.

  Further, the lifting function unit that has separated the refill container part can be assembled with a new refill container part as it is by separating the refill container part, so that a preferable handling situation can be obtained.

  Furthermore, since the separation of the refill container part from the lifting function part is achieved by forcibly releasing the lifting cylinder with respect to the lifting piece, the impact associated with the unlocking can be sensed by the user as a tactile sensation, Thereby, a reliable separation operation can be obtained.

  In the case where the lowering piece is composed of a locking cylinder piece and a leg piece having a locking strip, a portion with a locking assembly for the piston of the lowering piece, and a portion with a locking assembly for the lifting cylinder Can be formed separately, so that the locking force of the both can be set separately, thereby obtaining an appropriate separating operation utilizing the descending operation of the lifting cylinder.

  In the case where the bottom cap is assembled to the refill container part, the pull-down piece, which is a functional part of the refill container part, can be sealed and stored in the storage cylinder so that the refill container part is independent. Can be handled safely.

  Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings.

  The liquid content discharge container (see FIG. 1) in the illustrated embodiment includes a refill container portion 1 that stores the content N and a carry-up function portion 16 that discharges the content N from the refill container portion 1. Has been.

  The refill container portion 1 includes a storage cylinder body 2 in which a lower end portion of a linear cylindrical main body portion is reduced in diameter via a stepped portion and a thread is engraved on an outer peripheral surface to form an assembled cylinder piece 25; A short-cylindrical discharge cap 3 that is tightly fitted to the upper end opening of the storage cylinder 2 by a combined cylinder 6 and has a discharge port 5 in the center of the top plate 4, and the discharge cap 3 The opening / closing lid 7 that seals the discharge port 5 by the stopper piece 8, the piston 9 that is inserted into the storage cylinder 2 and can be moved up and down while being in close sliding contact, and the engagement assembly is attached to the lower side of the piston 9 It is comprised from the pulling-down piece 11 to do.

  The top surface of the top plate 4 of the discharge cap 3 is a smooth surface so that the discharged content N is positioned in a posture that facilitates the coating process. In the case of the illustrated embodiment, the discharged content N is further incorrect. It has a gentle concave surface so that it does not flow down.

  The piston 9 has a bottomed cylindrical shape, and is provided with a resilient contact portion in close contact with the inner peripheral surface of the storage cylinder 2 around the cylindrical wall. The short cylindrical-shaped engagement cylinder piece 10 is suspended.

  The pull-up piece 11 is suspended from the bottom cylindrical center of the bottom cylindrical wall 12 of the bottomed short cylindrical shape that fits and engages with the engagement tube piece 10 of the piston 9. The leg piece 13 is formed on the outer peripheral surface of the locking cylinder piece 12, and is provided with a protrusion for undercut coupling with the engaging cylinder piece 10. 14 is projectingly provided.

  In addition, the refill container part 1 of the state which filled the content N, sealed the discharge outlet 5 with the opening-and-closing lid 7, and attached the bottom cap 15 to the cylinder piece 25 with the assembly formed in the lower end part of the storage cylinder 2. (Refer to FIG. 2) is in a state in which the lifting piece 11 which is a functional part of the refill container 1 is sealed and protected, so that it can be safely handled as a single refill container.

  The lifting function portion 16 has a linear cylindrical shape, and a main body cylinder 17 having an upper end portion which is formed with a screw thread on the inner peripheral surface thereof and a lower end of the main body cylinder 17 is rotatable. A bottomed cylindrical rotary knob 19 coupled with an undercut and a lifting cylinder 21 that is inserted and assembled to the main body cylinder 17 so as to be movable up and down with respect to the main body cylinder 17 and the rotary knob 19. Yes.

  A key groove 18 is provided on the inner peripheral surface of the main body cylinder 17 over substantially the entire height range, and the screwed cylinder portion 26 in which a thread is engraved on the inner peripheral surface of the upper end portion is provided at the lower end of the storage cylinder 2. The part-attached cylinder piece 25 is a part to which the screwed assembly is attached.

  The rotary knob 19 has a bottomed cylindrical shape, and is a straight bar-like spiral in which a thread is engraved on the outer peripheral surface from the center of the upper surface of the bottom wall of the main body portion that is pivotally undercut coupled to the lower end portion of the main body cylinder 17. The rod 20 is erected.

  The lifting cylinder 21 is provided with a key 23 that engages with the key groove 18 at the lower end portion of the outer peripheral surface of the main body cylinder portion, and is similarly screwed into the lower end portion of the inner peripheral surface of the main body cylinder portion. A fitting tube piece 24 is provided integrally, and a locking projection piece 22 that climbs over the locking strip 14 of the lowering piece body 11 and locks it from above is fitted on the inner peripheral surface of the upper end portion as shown in FIG. Assemble them integrally and project them diagonally downward.

  When the refill container portion 1 is assembled to the lifting function portion 16, the upper end surface of the lifting cylinder 21 comes into contact with the lower end surface of the engagement cylinder piece 10 of the piston 9, and the locking protrusion 22 is attached to the locking strip 14. On the other hand, it climbs over and is locked from above, and the leg piece 13 has its lower end opposed to the upper end of the spiral rod 20.

  From this state, when the rotary knob 19 is rotated with respect to the main body cylinder 17 to raise the raising cylinder body 21, the piston 9 is pushed up by the raising cylinder body 21, and the amount of pushing up of the piston 9 is increased. A corresponding amount of the content N is discharged onto the top plate 4 of the discharge cap 3 from the opened discharge port 5. At this time, the lifting piece 11 is displaced upward together with the piston 9.

  As the consumption of the contents N progresses and the piston 9 reaches the rising limit position as shown by the two-dot chain line in FIG. 1, the refill container portion 1 is in a state where the contents N have been used up.

  As shown in FIG. 4, the separation of the refill container unit 1 from the feed-out function unit 16 is finally achieved by lowering the pull-down cylinder 21 to the lower limit position and detaching the pull-down piece 11. However, the unscrewing of the storage cylinder 2 from the main body cylinder 17 is performed separately from the detachment of the lifting piece 11 from the raising cylinder 21.

  For example, in the state of FIG. 1, the refill container portion 1 is screwed out from the feeding function portion 16 and then lifted, and the piston 9 to the step portion (located at the upper end of the assembled cylinder piece 25) of the storage cylinder body 2. 3 is used by releasing the engagement between the piston 9 and the pull-down piece 11 and separating them, and from this state, the rotary knob 19 is operated to Lower to the lower limit position shown in FIG.

  Further, from the state indicated by the two-dot chain line in FIG. 1, the rotary knob 19 is operated in reverse to lower the lifting cylinder 21 together with the piston 9 and the pulling piece 11 to the lower limit position, and the assembled cylinder The piston 9 and the lifting piece 11 are disengaged by the abutment of the piston 9 with respect to the upper end of the piece 25, and the lifting piece 11 is brought into contact with the spiral bar 20 by the abutment of the leg piece 13 of the lifting piece pair 11. The engagement with the lifting cylinder 21 is released, and the storage cylinder 2 is screwed off from the main body cylinder 17 to obtain the state shown in FIG.

  4, the detachment operation of the lowering piece body 11 and the raising cylinder body 21 is caused by the downward displacement of the lowering piece body 11 and the raising cylinder body 21 together, and the lowering limit of the feeding cylinder body 21 is increased. Immediately before the position, the pulling piece 11 abuts the leg piece 13 against the upper end of the spiral rod 20 and cannot be further displaced downward, whereas the feeding cylinder 21 is displaced downward as it is. Then, the locking of the locking strip 14 and the locking projection 22 is released, whereby the refill container portion 1 can be separated from the feeding function portion 16.

  When the locking of the locking strip 14 and the locking projection 22 is released, the locking projection 22 forcibly climbs over the locking strip 14, so that the mechanical movement associated with this forcible climbing operation is performed. It can be confirmed that the impact is transmitted as a tactile sensation to the hand of the person who operates the device, and thereby the refill container unit 1 can be separated from the carry-up function unit 16.

  Since the state on the side of the carry-up function unit 16 is the same as the state in which the refill container unit 1 can be assembled as shown in FIG. 1, the operation for removing the refill container unit 1 of the carry-up function unit 16 is as follows. This is also a return operation to a state where the new refill container portion 1 can be assembled.

  As described above, the liquid content discharge container of the present invention can easily, safely, and efficiently perform the attachment / detachment handling process of the refill container portion that directly discharges the liquid content with the lifting function portion. As a discharge container using a refill container, a wide range of usage can be expected.
