Abstract

<P>PROBLEM TO BE SOLVED: To provide a quantitative dispensing container whose measuring condition and dispensing condition do not overlap for accurate measuring operation and safety dispensing operation. <P>SOLUTION: Both supply opening 12 and dispensing opening 21 of a measuring chamber K for measuring a content liquid N to be dispensed are closed at the same time when its condition is switched from the "measuring condition" to the "dispensing condition". By this configuration, during the dispensing condition, the irregular dispensing of the content liquid N remaining unmeasured is surely prevented for a safe and accurate dispensing/measuring operation. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a quantitative discharge container capable of measuring and discharging a stored content liquid such as a hair-growth agent or a cosmetic liquid in a predetermined amount corresponding to a single use amount.

As a conventional technique of a fixed volume discharge container that measures and discharges a stored liquid such as a hair restorer or cosmetic liquid to a certain amount each time it is used, the cylindrical portion arranged in the inner plug is appropriately moved up and down, By alternately opening and closing the first valve and the second valve, the content liquid in the container body was poured into the measuring cylinder part and weighed, and the content liquid in this measuring cylinder part was poured out from the spout .
JP 2002-337910 A

  However, in the above-described prior art, there is a state in which both valves are “open” when switching from the metering state in which the first valve is open to the dispensing state in which the second valve is open. For this reason, there is a problem that a larger amount of the content liquid than the weighed amount is dispensed.

  Therefore, the present invention was devised to solve the above-described problems in the prior art, and it is a technical problem to prevent the metering state and the discharge state from overlapping in the fixed-quantity discharge container. The purpose is to obtain a weighing operation and a safe discharge operation.

  The fixed-quantity discharge container according to the present invention includes a bottle-shaped container main body that stores the content liquid, and a discharge cap that is closely assembled to the mouth tube portion of the container main body to measure and discharge the fixed content liquid.

  The discharge cap includes a measuring chamber body that forms a measuring chamber, and a valve body that is assembled in the measuring chamber so that it can be displaced up and down and cannot be pulled out.

  The valve body opens and closes the supply side valve part that opens and closes the supply port that communicates with the container body of the weighing chamber at the lower end, and conversely opens and closes the discharge port that opens to the outside of the weighing chamber at the upper end part. Each discharge side valve portion is formed, and an operation piece that protrudes from the discharge port by forming a discharge passage is provided at the upper end.

  The metering chamber is a process in which the valve body is moved up and down in the metering chamber, and the discharge port closes and the supply port opens, and the metering chamber is closed. It will be in one of the “discharge states” that open and close the supply port.

  In the state where the valve body is located at the upper limit, the discharge port of the measurement chamber is sealed by the discharge side valve portion of the valve body, and the supply side valve portion of the valve body is separated upward from the supply port of the measurement chamber. Then, it is opened and is in a “metering state”, and the operation piece of the valve body protrudes from the discharge port.

  When the container is inverted in this “measurement state”, the content liquid in the container body flows down from the supply port into the measurement chamber, and the measurement chamber is filled with the content liquid.

  In this state (with the container upside down), push the protruding valve body operation piece against the surface to be coated, such as the scalp, and push it into the measuring chamber to move the valve body upwardly relative to the measuring chamber. Let

  When the valve body is displaced to the upper limit, the supply port of the measurement chamber is sealed by the supply side valve portion of the valve body, and the discharge side valve portion of the valve body is separated upward from the discharge port of the measurement chamber. Then, the liquid is released to be in a “discharge state”, and the content liquid measured in a certain amount in the measurement chamber is discharged from the discharge port and applied to the application surface.

  In the middle of switching from the “weighing state” to the “discharge state”, both the supply port and the discharge port are in a “measurement chamber sealed state”.

  For this reason, in the “discharge state” in which the discharge port is opened, the supply port is always sealed, so that only the content liquid measured in a fixed amount is discharged.

  Similarly, in the “metering state”, since the discharge port is always sealed, the content liquid does not leak from the discharge port in the weighing operation state.

  Another configuration of the present invention is that the supply side valve unit seals the supply port directly above the supply side valve unit of the valve body, and the discharge side valve unit opens the discharge port. A supply-side stopper is installed to prevent the valve body from rising, and the discharge-side valve part seals the discharge port directly below the discharge-side valve part. A discharge-side stopper that disables the operation is provided.

  If the valve body is provided with a supply-side stopper and a discharge-side stopper, the assembled state in which the valve body can be moved up and down relative to the weighing chamber body can be made stable, and the "weighing state" In addition, it becomes easy to set and hold the “discharge state”.

  Another configuration of the present invention is that the weighing chamber body is closely assembled to the mouth tube portion of the container main body, and the inner plug body that forms the supply port and the inner plug body are closely assembled to measure. And forming a chamber and a cap body having an opening at the upper end.

  In the case where the measuring chamber body is composed of the inner plug body and the cap body, the valve body can be easily moved up and down and the assembling that cannot be removed is easily obtained. The body structure is simplified.

  Further, according to another configuration of the present invention, a locking protrusion is formed on the opening surface of the discharge port of the measuring chamber body, and the locking protrusion is moved over and locked to the outer peripheral surface of the discharge side valve portion of the valve body from above. That is, there are provided locking peripheral strips.

  If the discharge port has a locking protrusion and the discharge valve has a locking peripheral, the metering state is maintained by the locking of the locking protrusion and the locking peripheral. , Prevents unnecessary displacement of the valve body in the “weighing state”.

  Another configuration of the present invention resides in that a plurality of longitudinal groove-shaped discharge grooves are formed on the outer peripheral surface of the operation piece of the valve body over the entire height range.

  In the case where the operation piece of the valve body is provided with a discharge groove, a passage for smoothly discharging the measured content liquid is ensured regardless of whether the operation piece is pressed against the coated surface.

  According to another configuration of the present invention, the discharge port of the measuring chamber body is formed by a discharge cylinder erected at the upper end of the measuring chamber body, and the valve function portion of the discharge side valve portion of the valve body is formed in the discharge cylinder. That is, it is formed with a locking peripheral strip that is in close sliding contact with the peripheral surface.

  In the case where the discharge port is made up of a discharge cylinder and the valve function part of the discharge side valve part is made up of a locking peripheral, the stroke at which the discharge side valve part seals the discharge port becomes large. Thus, the switching stroke between the “metering state” and the “discharge state” can be increased.

Since the present invention has the above-described configuration, the following effects can be obtained.
In the present invention, the supply port and the discharge port are never opened at the same time, and the supply port and the discharge port are in the middle of switching from the “metering state” to the “discharge state”. Since both are sealed, the “measurement chamber is sealed”, it is possible to stably and accurately discharge the measured content liquid and to obtain a safe and accurate measurement operation.

  If the valve body is provided with a supply-side stopper and a discharge-side stopper, the valve body can be moved up and down stably, and setting and holding of the “weighing state” and “discharge state” is easy. Therefore, switching between the “metering state” and the “discharge state” can be achieved smoothly, reliably and accurately.

  In the case where the measuring chamber body is composed of the inner plug body and the cap body, the assembly of the valve body with respect to the measuring chamber body which can be displaced up and down and cannot be removed easily can be obtained. Easy to configure.

  In the case where a locking protrusion is provided at the discharge port and a locking peripheral line is provided at the discharge side valve section, unnecessary displacement of the valve body in the `` weighing state '' is prevented. Liquid leakage can be reliably prevented and a safe metering operation can be obtained.

  If the valve body is provided with a discharge groove on the operation piece, a passage through which the measured content can be smoothly projected can be secured. A stable and smooth discharge of the liquid can be obtained.

  When the discharge port is made up of a discharge cylinder and the valve function part of the discharge side valve part is made up of a locking peripheral, the switching stroke between the “metering state” and the “discharge state” can be increased. Therefore, it is possible to obtain an appropriate and stable switching operation between the “metering state” and the “discharge state”.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

At the center of the lower surface, a plug cylinder piece 39 that closely fits the discharge cylinder 22 of the discharge cap 4 and an engagement piece 40 that engages and engages with the operation piece 31 of the valve body 24 are provided. From the end, an outer cylinder 38 that surrounds the screwed cylinder 37 and adjusts the appearance of the outer cap 35 is suspended.

  The discharge cap 4 (refer particularly to FIGS. 5, 7, and 9) is closely assembled to the mouth tube portion 2 of the container body 1, and a supply port that is a communication port with the inside of the container body 1 on the lower side. 12, the discharge port 21 that is an open port to the outside is formed on the upper side, and the measuring chamber body 5 that forms the measuring chamber K having a constant volume, and can be displaced up and down in the measuring chamber body 5. The valve body 24 is configured to open and close the supply port 12 and the discharge port 21 and project the operation piece 31 at the upper end from the discharge port 21.

  The measuring chamber body 5 has a lower half middle plug body 6 that is tightly assembled to the mouth tube portion 2, and an upper half cap body 15 that is closely assembled to the inner plug body 6 to form a measuring chamber K. Are combined.

  The inner plug body 6 is provided with a fitting cylinder piece 10 that is tightly fitted into the engagement cylinder piece 3 from the inner lower end of the main body cylinder 7 located on the engagement cylinder piece 3 of the mouth tube portion 2, and the main body cylinder. A circular ring plate-shaped inner flange piece 11 is provided around the lower end portion of the inner peripheral surface of the inner peripheral surface 7, and a leg tube piece 13 a that forms a supply port 12 is suspended from the inner peripheral edge of the inner flange piece 11. At the lower end of the tube piece 13a, a bar piece 14 is provided in a continuous manner at the center portion via a plurality of leg pieces 13.

  The main body cylinder 7 is composed of a lower half locking cylinder portion 8 provided with locking protrusions on the outer peripheral surface, and an upper half tight fitting cylinder portion 9 provided with a plurality of seal strips on the outer peripheral surface. Has been.

  The cap main body 15 has a measuring cylinder portion 19 in which a dome-shaped top wall piece 20 is connected to the upper end of a main cylinder 16 that is tightly fitted to the main body cylinder 7 of the inner plug body 6 and has a locking assembly. The discharge cylinder 22 is formed upright at the center of the top wall piece 20 so as to form the discharge port 21.

  The main cylinder 16 climbs over and engages with the locking cylinder portion 8 of the inner plug body 6, and climbs over and engages with the engagement cylinder piece 3 of the mouth cylinder portion 2. The inner plug body 6 is tightly fitted to the tightly fitting cylinder portion 9 and is formed of a close contact cylinder portion 18 in the upper half. The inner peripheral surface of the discharge cylinder 22 has a slightly upper inner peripheral surface. A locking protrusion 23 having a stepped structure for expanding the diameter is formed.

  The valve body 24 has a cylindrical shape as a whole, and is composed of a main portion of the valve cylinder 25 and an operation piece 31 that is provided at the upper end of the valve cylinder 25 with a slightly reduced diameter. .

  The lower end of the valve cylinder 25 is configured as a supply side valve section 26 that can be inserted into the leg cylinder 13a, that is, the supply port 12, and the upper end of the valve cylinder 25 can be inserted into the discharge cylinder 22, that is, the discharge port 21. The discharge side valve portion 27 is formed in the above.

  At the lower end of the outer peripheral surface of the supply side valve portion 26, there is provided a seal peripheral line 26a that forms a valve function portion in close contact with the supply port 12, and similarly, at the upper end of the outer peripheral surface of the discharge side valve portion 27, A locking circumferential line 28 is provided which forms a valve function portion in close sliding contact with the discharge port 21.

  A locking protrusion 28 having a low protruding height, which is provided at the upper end of the discharge side valve portion 27 and functions as a sealing strip, is closely locked to the locking protrusion 23 of the discharge cylinder 22 in the “measurement state”. By doing so, the posture of the valve body 24 is stably held.

  Further, an outer flange-like supply-side stopper 29 is provided at the valve cylinder 25 portion located at the upper end of the supply-side valve portion 26, and this supply-side stopper 29 hits the inner flange piece 11 of the measuring chamber body 5. Thus, the lowering displacement limit of the valve body 24 is set.

  Similarly, a discharge side stopper 30 having an enlarged diameter step is provided on the valve cylinder 25 located at the lower end of the discharge side valve portion 27, and this discharge side stopper 30 is connected to the edge of the discharge port 21 of the measuring chamber body 5. The rising displacement limit of the valve body 24 is set.

  The operation piece 31 erected continuously at the upper end of the discharge side valve portion 27 has a height higher than that of the discharge cylinder 22, and a closing wall 32 is provided in the inside thereof, so that the inside of the valve body 24 is directed to the outside. It is closed, and four discharge grooves 33 in the form of vertical grooves are provided on the outer peripheral surface over the entire height range. The operation piece 31 may be the same height as the discharge cylinder 22 and may have six longitudinal groove-like discharge grooves 33.

  An engagement piece 40 of the outer cap 35 slides between the measuring chamber body 5 and the valve body 24 at the upper end of the inner peripheral surface of the upper end of the operation piece 31 above the closing wall 32. A locking piece 34 that locks with a locking force larger than the resistance force is provided so as to be engaged with the engaging piece 40 so as to hold the locking piece 34 with the engaging piece 40. A projecting piece projects from the center of the upper surface of the closing wall 32.

  A guide cylinder piece 32a that loosely fits on the rod piece 14 is suspended from the lower surface of the closing wall 32, and the measuring chamber body of the valve body 24 is slid by sliding the guide cylinder piece 32a with respect to the rod piece 14. 5 is stabilized.

  In the discharge cap 4 composed of the measuring chamber body 5 and the valve body 24, the seal circumferential line 26a of the valve body 24 that has descended rises from the seal circumferential line initial contact portion that is the portion of the leg cylinder piece 13a that first contacts. The distance between the engagement circumferential stripe 28 of the valve body 24 and the engagement circumferential first contact portion, which is the discharge cylinder 22 portion that contacts first, is the inter-mouth distance a, and the supply side valve portion 26 of the valve body 24 is sealed. The distance from the circumferential line 26a to the locking circumferential line 28 of the discharge side valve portion 27 is the inter-valve distance b, and the inter-valve distance b is set equal to or greater than the inter-mouth distance a.

  As described above, in the illustrated embodiment, by setting the inter-valve distance b to a value equal to or greater than the inter-port distance a, the seal circumferential strip 26a is in close sliding contact with the supply port 12. Thus, a state in which the locking circumference 28 is in close sliding contact with the discharge port 21, that is, a “measuring chamber sealed state” can be caused to appear.

Next, the discharge operation of the content liquid N will be described.
In the closed state of the container in which the outer cap 35 is screwed to the container main body 1 shown in FIG. 1, the valve body 24 is located at the lower limit and the supply port 12 is closed. The cylinder piece 39 is tightly fitted to the discharge cylinder 22 of the discharge cap 4 to close the discharge port 21, and the engagement piece 40 of the outer cap 35 is locked to the locking piece 34 of the valve body 24.

  From this state, when the outer cap 35 is screwed and raised with respect to the container body 1 (see FIG. 2), the valve body 24 also rises to the upper limit together by the locking of the locking piece 34 and the locking piece 40. Then, the valve body 24 opens the supply port 12 and closes the discharge port 21.

  Further, when the outer cap 35 is raised with respect to the container body 1 until it is completely screwed off (see FIG. 3), the valve body 24 positioned at the ascending limit cannot be moved up and displaced. Is released.

  When the container body 1 with the outer cap 35 screwed is inverted (see FIGS. 4 and 5), the content liquid N in the container body 1 flows into the measurement chamber K from the opened supply port 12, The “measurement state” is entered, and the content liquid N to be discharged is measured.

  From this state, when the operation piece 31 is pressed against the application surface T such as the scalp while the container body 1 is in an inverted posture (see FIGS. 6 and 7), the valve is placed against the measuring chamber body 5. The body 24 is relatively displaced downward (in the drawing, upward displacement).

  Due to the displacement of the valve body 24, the discharge side valve portion 27 of the valve body 24 opens the discharge port 21 before the supply side valve portion 26 opens the relationship between the inter-port distance a and the inter-valve distance b. The supply port 12 is closed, and both the supply port 12 and the discharge port 21 are closed to enter the “measurement chamber sealed state”, and the measurement of the content liquid N is completed.

  From this state, when the operation piece 31 is further pushed in and the valve body 24 is displaced to the lowering (upward in the drawing) limit (see FIGS. 8 and 9), the supply port 12 is closed and the discharge port 21 is opened. The “discharging state” is opened, and the content liquid N measured in a certain amount in the measuring chamber K is discharged from the discharge port 21 onto the application surface T and applied.

  In this way, when switching from the “measurement state” to the “discharge state” for discharging the measured content liquid N, the “measurement chamber sealed state” in which both the supply port 12 and the discharge port 21 are closed is surely closed. Thus, since the supply port 12 and the discharge port 21 do not open at the same time, no content liquid N other than the measured content liquid N is discharged at all.

  Since the discharge groove 33 for forming the discharge passage for the content liquid N is provided on the outer peripheral surface of the operation piece 31, even if the operation piece 31 is pressed against the surface to be coated T, this pressing will discharge the content liquid N. It will not get in the way.
