FIG. 5 is a diagram showing a state in which the fulcrum rods 16 and 17 are attached to the upright member 12 of FIG. The fulcrum rods 16 and 17 include rod portions 161, 171 and fitting portions 162 (see FIG. 2) and 172.

In the fulcrum rods 16 and 17, the rod portions 161, 171 extend in the width direction (± X direction), and the cross section T is formed at the end portion of the rod portions 161, 171 on the width direction (± X direction) on the central portion side. It has fitting portions 162 and 172 which are character-shaped end plates, and the fitting portions 162 and 172 are moved by being fitted into guide grooves 121 and 122 which are T grooves of the upright member 12, respectively.

Further, as shown in FIG. 5, the lengths of the fulcrum rods 16 and 17 in the width direction (± X direction) of the rod portions 161, 171 are provided so as to protrude from the surrounding portion 111 in the state of being attached to the upright member 12. Has been done.

Further, as shown in the side views of FIGS. 5 and 6A, the guide grooves 121 and 122 of the upright member 12 are formed at positions higher than the upper edge of the enclosing portion 111 of the reinforcing support portion 11. Therefore, the fulcrum rods 16 and 17 can move horizontally without being disturbed by the surrounding portion 111.

FIG. 6 is a diagram showing a state in which the operating member 15 is attached to the head 123 of the standing member 12 of FIG.

The operating member 15 is a substantially rectangular frame 151 that is long in the depth direction (± Y direction), and a pivot fixed shaft 152 is provided at a central portion in the depth direction.

The inner edge of the frame 151 constituting the operating member 15 is larger than the substantially rectangular shape of the outer edge of the head 123 of the standing member 12. Therefore, the pivot fixing shaft 152 is fitted and fixed from above to the shaft groove 124 of the head 123 of the upright member 12 shown in FIG.

Therefore, the operating member 15 can pivot like a seesaw in the front-rear direction (± Y direction) with the pivot fixed shaft 152 fitted in the shaft groove 124 of the standing member 12 as a fulcrum (rotation axis). Further, a connecting shaft 153 extending in the left-right direction is provided at an end portion (+ Y end) of the operating member 15. At the time of pivoting, one end of the operating member 15 is the free end A, and the other end provided with the connecting shaft 153 is the connecting end B.

FIG. 7 is a diagram in which the fulcrum rods 16 and 17 and the transmission members 18 and 19 are attached to the upright member 12 of FIG.

As shown in FIG. 7, elongated holes 181, 191 which are long through holes (holes) in the front-rear direction are formed on the side surfaces (± X plane) of the transmission members 18 and 19.

One end of the transmission members 18 and 19 is a force point, and the other end is an action point for pressing the stems 223 and 323 of the plurality of discharge containers 20 and 30.

The fulcrum rods 16 and 17 are provided between one end and the other end of the plurality of transmission members 18 and 19, and function as fulcrum axes serving as fulcrums for the pivots of the plurality of transmission members 18 and 19. Further, the positions of the fulcrum rods 16 and 17 can be moved between one end and the other end of the plurality of transmission members 18 and 19.

By moving the positions of the fulcrum rods 16 and 17, which are a plurality of fulcrum axes, the displacement amount of the action points of the transmission members 18 and 19 when a force is applied to the force points of the transmission members 18 and 19 is changed. The discharge amounts of the plurality of discharge containers 20 and 30 are adjusted.

Further, at one end of the transmission members 18 and 19 in the depth direction, connecting holes 182 and 192 into which the connecting shaft 153 of the operating member 15 is inserted are formed. By fitting the connecting holes 182 and 192 of the transmission members 18 and 19 with the connecting shaft 153, one end becomes a connecting end C in which the connecting end of the moving transmission member moves upward together with the connecting end of the operating member 15.

In the present embodiment, the connecting shaft 153, which is the connecting portion, is cylindrical, and the connecting holes 182 and 192 are cylindrical holes, but the connecting configuration is not limited to this example. .. For example, cylindrical convex portions (connecting protrusions) may be provided on the transmission members 18 and 19 sides, and cylindrical holes (connecting holes) may be provided on both sides of the operating member 15.

Further, the other ends of the transmission members 18 and 19 in the depth direction are bifurcated portions 183 and 193 that are bifurcated. The bifurcated portions 183 and 193 sandwich the stems 223 and 323 of the cap portions 22 and 32 of the discharge containers 20 and 30. The ends of the bifurcated portions 183 and 193 come into contact with the upper surfaces of the flange portions 131 and 141 of the flange members 13 and 14 (see FIG. 9A), and become the working end (operating end) D.

FIG. 8 shows an upright member 12, an operating member 15, transmission members 18, 19, and fulcrum rods 16, 17. In FIG. 8, (a) is a top view and (b) is a side view.

With reference to FIGS. 8 (a) and 8 (b), the operating member 15 is provided with a plurality of operating members 15 by the connecting shaft 153 in a state where the end portion (B) on the −Y side is sandwiched between the plurality of transmission members 18 and 19. It is connected to the connecting end C of the transmission members 18 and 19 of the above.

To achieve the state shown in FIG. 8, for example, from the state shown in FIG. 6, the fulcrum rod 16 is first attached to the upright member 12. Then, with the fulcrum rod 16 inserted into the elongated hole 181 (see FIG. 6) of the transmission member 18, the transmission member 18 is pushed along the fulcrum rod 16 from the side toward the center until it comes into contact with the upright member 12. , The connecting shaft 153 of the operating member 15 is inserted into the connecting hole 182 of the transmission member 18 and attached.

Similarly, for the transmission member in the opposite direction, after the fulcrum rod 17 is set in the upright member 12, the transmission member 19 is inserted along the fulcrum rod 17 with the fulcrum rod 17 inserted into the elongated hole 191 of the transmission member 19. It is pushed toward the center from the side toward the upright member 12, and the connecting shaft 153 of the operating member 15 is inserted into the connecting hole 192 of the transmission member 19 and attached. The order of attachment of the transmission members 18 and 19 is random.

Alternatively, as shown in FIG. 7, in a state where the fulcrum rods 16 and 17 are set on the upright member 12 first, the operation member 15 is attached to the upright member 12 later, and then the connecting shaft 153 of the operation member 15 is transmitted. It may be inserted and attached to the connecting holes 182 and 192 of the members 18 and 19.

After being set as shown in FIG. 8A, the positions of the plurality of fulcrum rods 16 and 17 in the front-rear direction with respect to the upright member 12 and the elongated holes 181, 191 are adjusted, respectively. In FIG. 8, the discharge containers 20 and 30 are omitted in order to explain the operation of the discharge amount adjusting mechanism 10, but in reality, the ends of the transmission members 18 and 19 are shown as shown in FIGS. 9 and 10. The part D is interlocked with the bent nozzles 23 and 33, which are the heads of the discharge containers 20 and 30.

By adjusting the fulcrum rods 16 and 17, when the free end (+ Y side end) of the operating member 15 is pressed downward, the pivot of the operating member 15 presses it by the other ends of the transmitting members 18 and 19. The pushing down amounts of the flange members 13 and 14 to be formed are adjusted, respectively, and the pushing down amounts of the nozzles 23 and 33 of the plurality of discharge containers 20 and 30 are adjusted. That is, the positions of the fulcrum rods 16 and 17 with respect to the elongated holes 181, 191 of the transmission members 18 and 19 are adjusted, respectively.

Specifically, when the free end A of the operating member 15 is pushed downward as a force point, the operating member 15 pivots with the fixed shaft 152 as a fulcrum and the connecting end (supporting end) B is lifted upward. Then, when the connecting ends C of the transmission members 18 and 19 are lifted (moved upward) together with the connecting ends B of the operating member 15, the transmission members 18 and 19 are in contact with the elongated holes 181, 191 and the fulcrum rods 16 and 17. Of a lever (type 1 lever) configured to pivot with It works using the principle.

Therefore, by adjusting the positions of the plurality of fulcrum rods 16 and 17 in the front-rear direction, the positions of the pivotal fulcrums of the transmission members 18 and 19 are adjusted, and the free end A of the operating member 15 which is a force point is lowered. By adjusting the lowering amount of the working end D, which is the point of action when pushed down, the pushing down amount of the stems 223 and 323 of the plurality of discharge containers 20 and 30 is adjusted.

As shown in FIG. 4, since the shaft groove 124 of the upright member 12 is formed in the head 123, the operating member 15 is fitted into the guide grooves 121 and 122 as shown in FIG. 8 (b). It is attached at a position higher than the fulcrum rods 16 and 17. Further, as shown in FIG. 8A, the depth direction (front-back direction) of the operating member 15 is as shown in FIG. Wider than the depth direction.

Therefore, the operating member 15 is moved back and forth with the pivot fixed shaft 152 fitted in the shaft groove 124 of the standing member 12 as a fulcrum without being disturbed by the fulcrum rods 16 and 17 fitted in the guide grooves 121 and 122. It can be pivoted like a seesaw in the direction.

FIG. 9 is a side view illustrating the operations of the operation member 15, the transmission members 18, 19, the fulcrum rods 16, 17, the collar members 13, 14, the cap portions 22, 32, and the bent nozzles 23, 33. 9A and 9B are views showing a state in standby mode and FIG. 9B is a state in which the operating member 15 is pressed.

10A and 10B are views showing the positions of the fulcrum rods when different discharge amounts are set for the respective discharge containers 20 and 30, and in FIG. 10, FIG. 10A is a top view and (b). ) Is a rear view when the operating member is pressed.

In order to explain the movements of the collar members 13 and 14, the reinforcing support portion 11 and the upright member 12 are not shown in FIGS. 9 and 10.

As shown in FIG. 9, the flange members 13 and 14 are fixed to the lower ends of the bases 231 and 331 of the bent nozzles 23 and 33 of the plurality of discharge containers 20 and 30, respectively, and move up and down together with the bent nozzles 23 and 33. Moving. Further, the flange members 13 and 14 are slidably fitted to the outer periphery of the upper end of the stems 223 and 323 (tube portions) of the cap portions 22 and 32 of the plurality of discharge containers 20 and 30.

Therefore, the end Ds of the bifurcated portions 183 and 193 of the transmission members 18 and 19 press the upper surfaces of the flange portions 131 and 141 of the plurality of flange members 13 and 14, so that the bent nozzles 23 of the discharge containers 20 and 30 are formed. , 33 can be raised and lowered.

In this example, an example in which the collar members 13 and 14 are attached to the stems 223 and 323 has been described, but if there is a portion where the other ends of the transmission members 18 and 19 can be pressed, it is not necessary to attach the collar member. For example, a flange portion extending laterally may be integrally formed and provided at the upper ends of the respective stems 223 and 323. In this case, the transmission members 18 and 19 can press the stems 223 and 323 of the discharge containers 20 and 30 by pressing the upper surfaces of the plurality of flange portions at the other ends, respectively, and operate the piston to operate the contents. Can be discharged.

As shown in FIG. 10A, the stretching directions of the tip portions 232 and 332 of the bent nozzles 23 and 33 are in the same direction (direction) as the stretching direction of the operating member 15 (in the top view shown in FIG. 10A). It is preferable to mount the bending nozzles 23 and 33 on the flange members 13 and 14 in the same direction). By extending the extending direction of the tip portions 232 and 332 of the bent nozzles 23 and 33 in the same direction (parallel) as the operating member 15, the discharge direction E (see FIG. 9B) and the pivot of the operating member 15 The moving directions are the same, and the user's operability can be ensured without the tip portions 232 and 332 of the bent nozzles 23 and 33 colliding with the operating member 15.

Although this example shows an example in which the bending angles φ of the bending nozzles 23 and 33 are right angles, the bending of the bending nozzles 23 and 33 does not have to be right angles. At least, the bending angle φ may be such that the tips 232 and 332 of the bending nozzles 23 and 33 do not collide with the fulcrum rods 16 and 17 when pressed as shown in FIG. 9B. Alternatively, the bending angles of the bending nozzles 23 and 33 may be adjustable in the elevation angle direction.

<Discharge amount adjustment setting>
The relationship between the positions of the fulcrum rods 16 and 17 and the discharge amount will be described with reference to FIGS. 8 to 10.

The transmission member 18 is supported by two points of the connecting shaft 153 and the fulcrum rod 16 of the operating member 15, and the transmission member 19 is supported by two points of the connecting shaft 153 and the fulcrum rod 17. Therefore, as described above, when the connecting ends C of the transmission members 18 and 19 connected to the connecting shaft 153 rise upward, the bifurcated portions 183 and 193 of the working end D, which is the end of the working point, fall.

At this time, if the fulcrum rod 16 is close to the connecting shaft 153, for example, as in the fulcrum rod 16 of FIGS. 8 and 10 (a), the distance between the connecting hole 182 and the fulcrum rod 16 in the transmission member 18 of FIG. It gets shorter. Therefore, as the connecting shaft 153 rises when the free end A of the operating member 15 is pressed, the length at which the transmission member 18 is pulled up with respect to the fulcrum rod 16 becomes short (the distance between the force point and the fulcrum becomes short). The depression angle θ (see FIG. 8B) of the inclination of the transmission member 18 with respect to the connecting shaft 153 becomes large and steep.

Therefore, since the inclination of the transmission member 18 is steep and the action end D side is longer than the contact point of the elongated hole 181 with the fulcrum rod 16 (the distance between the fulcrum and the action point is long), the action of the transmission member 18 Since the bifurcated portion 183 on the end D side is greatly lowered and the collar member 13 is largely moved and pushed as shown on the right side of FIG. 10B, a large discharge amount of the discharge container 20 is set.

On the other hand, when the fulcrum rod 17 is far from the connecting shaft 153, for example, as in the fulcrum rod 17 of FIGS. 8 and 10 (a), the distance between the connecting hole 192 and the fulcrum rod 17 in the transmission member 19 becomes long. Therefore, as the connecting shaft 153 rises when the free end A of the operating member 15 is pressed, the length of the transmission member 19 being pulled up with respect to the fulcrum rod 17 becomes long (the distance between the force point and the fulcrum becomes long). The depression angle θ (see FIG. 8B) of the inclination of the transmission member 19 with respect to the connecting shaft 153 is small, and the inclination becomes gentle.

Therefore, the inclination of the transmission member 19 is gentle, and the working end D side is shorter than the contact point of the elongated hole 191 with the fulcrum rod 17 (the distance between the fulcrum and the working point is short). Since the bifurcated portion 193 is slightly lowered and the collar member 14 is slightly moved and pushed as shown on the left side of FIG. 10B, the discharge amount of the discharge container 30 is set to be small.

As described above, in the discharge amount adjusting mechanism of the present invention, by adjusting the positions of the fulcrum rods 16 and 17, the depression angles (inclinations) of the transmission members 18 and 19 when the force point A of the operating member 15 is pressed are different. Two or more contents can be discharged in an arbitrarily selected amount.

Further, since the transmission members 18 and 19 are connected to the operation member 15 by fitting the connecting holes 182 and 192 and the connecting shaft 153, respectively, even if the pushing down of the operating member 15 is stopped in the middle, the transmission member 18, Since both of 19 are pivoted and the flange members 13 and 14 on which the point of action acts are lowered, the smaller of the plurality of discharge containers 20 and 30 can be discharged, and the discharge ratio is high. It does not change.

Since the required load on the force point for moving the point of action changes depending on the positions of the fulcrum rods 16 and 17 for adjusting the discharge amount, the weight (feeling) when the operating member is pressed by the user changes. do. For example, when both of the two discharge containers have a large discharge amount, the operating member becomes heavy.

Here, even when the operating member becomes heavy, the free end of the operating member may be stretchable so that even a person with a weak force can operate it with a light force. For example, a folding method or a sliding method can be assumed as the stretching method. By lengthening the free end of the operating member, the required load at the point of effort is reduced by the principle of leverage, and the head of the discharge container can be pressed with a light force.

In the above example, the fulcrum rods 16 and 17 functioning as the fulcrum shafts are shown in the rod shape, but the fulcrum rods 16 and 17 include plate-shaped ones.

Further, in the above example, the fulcrum rods 16 and 17 are fitted to the upright member 12, but if the fulcrum rods 16 and 17 function as the fulcrum shafts of the transmission members 18 and 19, the other It may be supported by a member of.

When the transmission members 18A and 19A are pivoted, the contact points between the regulation members 165 and 175 and the elongated holes 181A and 191A function as fulcrums that regulate the vertical positions of the transmission members 18A and 19A. Note that FIG. 11 shows an example in which the elongated holes 181A and 191A of the transmission members 18A and 19A are formed on the outer side far from the operating member 15, and the regulating members 165 and 175 are installed so as to extend outward. However, the elongated holes 181A and 191A may be formed on the central side close to the operating member 15, and in this case, the regulating members 165 and 175 are installed so as to extend toward the central side.

Holes (holes) 1113 and 1114 and guide grooves (guides) 1115 and 1116 are formed.

In this configuration, the side wall of the surrounding portion 111 extends upward higher than the configuration shown in FIG. 6A, and the fulcrum rods 16C and 17C are inserted into the elongated holes 1113 and 1114 of the side surfaces 1111, 1112. ing.

The fulcrum rods 16C and 17C have fitting portions 168 and 178 that are fitted with guide grooves 1115 and 1116 on the side surfaces 1111 and 1112, respectively. The fulcrum rods 16C and 17C can slide in the front-rear direction along the elongated holes 1113 and 1114 while being restricted by the plurality of guide grooves 1115 and 1116 so as not to rotate. The fitting portions 168 and 178 are flange portions provided at portions other than the ends of the fulcrum rods 16C and 17C.

Further, in this configuration, unlike FIG. 7, the end portion of the fulcrum rods 16C and 17C on the central portion side is not fitted to the upright member 12, and the rod portion is prevented from coming off from the transmission members 18 and 19. Retainers 169 and 179 are provided at the central ends of 161C and 171C. The shape of the retaining 169 and 179 may be any shape as long as the fulcrum rods 16C and 17C can be prevented from coming out from the transmission members 18 and 19 in the outward direction. Further, a recess may be provided on the side surface of the transmission members 18 and 19 on the center side so that the amount of protrusion on the center side of the retaining members 169 and 179 does not increase.

Alternatively, the fulcrum rod is fitted to the fitting portions 164 and 174 provided at the lower ends of the beam plate 112 shown in FIG. 12 and fitted to the side wall of the surrounding portion 111 shown in FIG. By having both the fitting portions 168 and 178 provided near the end portion, the fitting portions 168 and 178 may be supported at two points, the lower end and the side.

Although the guide portion fitted with the fulcrum rod is an example of a guide groove in FIGS. 11, 12, and 13, the upper surface 1121 of the beam plate 112 and the side surfaces 1111, 1112 of the enclosure 111 are also shown. The shape of the guide portion is not limited to the guide groove. For example, the guide portion provided on the upper surface of the beam plate or the side surface of the enclosure portion may be a guide elongated hole penetrating the upper surface of the beam plate or the side wall of the enclosure portion, or the end portion of the fulcrum rod. It may be a guide protrusion that fits with the concave fitting portion.

<Installation of discharge amount adjustment mechanism>
Next, the attachment of the discharge amount adjusting mechanism of the present invention to the two discharge containers 20 and 30 will be described with reference to FIG.

FIG. 14 is a sequence diagram showing a flow of attaching the discharge amount adjusting mechanism of the present invention to two discharge containers.

First, the operating member 15 is attached to the upright member 12 (FIG. 14 (a) ⇒ FIG. 14 (b)).

Next, the fulcrum rods 16 and 17 are attached to the upright member 12 (FIG. 14 (b) ⇒ FIG. 14 (c)). The order of mounting the operating member 15 and the fulcrum rods 16 and 17 may be reversed.

Then, from under the reinforcing support portion 11, the cap portions 22 and 32 and the flange members 13 and 14 attached to the tops of the stems 223 and 323 of the cap portions 22 and 32 are inserted, and the beam plate 112 of the reinforcing support portion 11 is inserted. Cap portions 22 and 32 are attached to the holes 113 and 114 of the above (FIG. 14 (d)).

Then, the transmission members 18 and 19 are attached to the operation member 15, and the operating ends D of the transmission members 18 and 19 are placed on the collar members 13 and 14 (FIG. 14 (e)).

After that, the bottle portions 21 and 31 are inserted from below the reinforcing support portion 11 (FIG. 14 (f)).

Then, the bending nozzles 23 and 33 are mounted on the flange members 13 and 14 (FIG. 14 (f) ⇒ FIG. 14 (g)).

After all the mounting is completed in this way, the positions of the fulcrum rods 16 and 17 in the front-rear direction are adjusted (FIG. 14 (h)).

It is set as described above, and when in use, it is discharged by pressing the free end A of the operating member 15.

Further, as shown in this sequence, the discharge amount adjusting mechanism 10 of the present invention is detachable from the two discharge containers 20 and 30. Further, in the discharge containers 20 and 30, the bottle portions 21 and 31 are removable from the cap portions 22 and 32.

As a result, when the inside of the bottle portions 21 and 31 is empty or the contents are reduced and the same contents are used, the bottle portions 21 and 31 are used for the discharge containers 20 and 30, respectively. Can be exchanged.

Even if the liquid content is used up in this way, the bottles 21 and 31 are removed and replaced in the order of FIG. 14 (f) ⇒ FIG. 14 (e), or the bottles 21 and 31 are temporarily removed. By filling the liquid and reattaching it, the cap portions 22, 32, the nozzles 23, 33, and the discharge amount adjusting mechanism 10 can be used for a long time.

Further, as described above, by adjusting the fulcrum rods 16 and 17, since the discharge ratios of the two discharge containers 20 and 30 are different, the contents of any of the bottle portions 21 and 31 disappear quickly. In that case, either one of the bottle portions 21 and 31 can be replaced at different timings.

<Cover>
FIG. 15 is a view in which a cover is attached to the discharge amount adjusting device of the present invention. A cover 40 may be provided above the reinforcing support portion 11.

The cover 40 shown in FIG. 15 has an opening O1 for the free end A of the operating member 15 and the vicinity of the nozzle holes of the tip portions 232 and 332 of the bent nozzles 23 and 33 so that the user can operate the cover 40. The openings O2 and O3 and the openings O4 and O5 near the ends of the fulcrum rods 16 and 17 are formed. Due to the openings O1 to O5, the free end A (power point) of the operating member 15, the vicinity of the nozzle holes of the tip portions 232 and 332 of the bent nozzles 23 and 33, and the outer ends of the rod portions 161 and 171 of the fulcrum rods 16 and 17 are provided. The vicinity of the portion protrudes outward from the cover 40. Therefore, by providing the cover 40, it is possible to prevent dust and the like from being inserted into the discharge amount adjusting mechanism 10 without affecting the operation.

Further, in this example, an example is shown in which the operating ends of the fulcrum rods 16 and 17 project in a rod shape from the cover 40, but the side ends of the fulcrum rods 16 and 17 that are not on the central portion side are covered with the cover 40. On the other hand, the shape may be a lever shape or a grip shape. Alternatively, the positions of the fulcrum rods 16 and 17 may be moved in conjunction with a stepwise adjustable button (for example, a circular dial button) provided on the cover 40.

Although FIG. 15 shows a diagram in which the cover 40 is attached to the discharge amount adjusting mechanism 10 shown in FIGS. 1 to 10, the discharge amount adjusting mechanisms 10A and 10B shown in FIGS. 11, 12, and 13 are shown. , 10C may be fitted with a cover 40.

When the cover 40 is attached to the discharge amount adjusting mechanism 10A shown in FIG. 11, the fulcrum rod 16A, is located on the upper surface (ceiling surface) of the cover 40 at a position corresponding to the guide grooves 1122 and 1123 of the upper surface 1121 of the beam plate 112. A cover having a structure in which an elongated hole extending in the front-rear direction is provided so that 17A can be inserted is used. In this configuration, the fulcrum rods are further provided on the fitting portions 164 and 174 provided at the lower end to be fitted to the upper surface 1121 of the beam plate 112 shown in FIG. Even if it has the same structure as the fitting portions 168 and 178 shown in FIG. 13 and has both fitting portions rotated by 90 ° and is supported by two points, the lower end and the upper side. good.

<Modification example of reinforcing support>
In the above example, the example in which the enclosing portion 111 of the reinforcing support portion 11 covers the entire side surfaces of the cap portions 22 and 32 and the bottle portions 21 and 31 like a housing has been described, but there are two standing members 12. The reinforcing support portion may be supported so as not to stand up and move in the substantially central portion with respect to the nozzles 23 and 33 of the discharge containers 20 and 30 of the above. Therefore, the surrounding portion may cover at least the vicinity of the cap portions 22 and 32 of the two discharge containers 20 and 30.

FIG. 16 shows a first modification of the reinforcing support portion of the discharge amount adjusting device of the present invention. FIG. 16 shows a configuration in which the enclosing portion 111A of the reinforcing support portion 11A covers the vicinity of the cap portions 22 and 32 in the shape of a rectangular parallelepiped with rounded corners in a top view. Also in this configuration, a flat plate-shaped beam plate 112 having holes 113 and 114 formed is provided which is connected to the surrounding portion 111A and supports the upright member 12.

FIG. 17 shows a second modification of the reinforcing support portion of the discharge amount adjusting device of the present invention.
In the configuration of FIG. 16 above, the surrounding portion 111A surrounding the cap portions 22 and 32 has an example of being rectangular with rounded corners in a top view, but may have an elliptical shape, for example, as shown in FIG. .. Also in this configuration, a flat plate-shaped beam plate 112B having holes 113 and 114 formed is provided which is connected to the surrounding portion 111B and supports the upright member 12.

Note that FIG. 17 shows an example in which the elliptical enclosing portion 111B of the reinforcing support portion 11B surrounds only the periphery of the cap portions 22 and 32 of the two discharge containers 20 and 30, but the elliptical enclosing portion is shown. It may cover the bottom of the bottle portions 21 and 31.

Further, in the examples of FIGS. 16 and 17 described above, in the reinforcing support portions 11A and 11B, the area of the surrounding portions 111A and 111B is small, but even if the reinforcing support portions are not provided with the surrounding portion. good.

For example, if the beam portion of the reinforcing support portion is fitted and fixed to the cap portions 22 and 32 of the two discharge containers 20 and 30, the position of the upright member 12 is fixed, so that the surrounding portion 111 Is unnecessary.

Further, although the example in which the beam portion is a flat beam plate 112 has been described above, for example, even if the operation member 15 and the transmission members 18 and 19 are pivotally moved, the upright member 12 is the bottle portion 21, 31 and the cap. The beam portion does not have to be plate-shaped as long as it is immovable with respect to the portions 22 and 32.

FIG. 18 shows a third modification of the reinforcing support portion of the discharge amount adjusting device of the present invention. As shown in FIG. 18, the frame portion 115 of the elliptical ring is collectively surrounded by the cap portions 22 and 32 of the two discharge containers 20 and 30, and the strip-shaped beam strip 116 is provided in the central portion of the ellipse. The upright member 12 may be fixed as the reinforcing support portion (beam portion) 11C. Further, two ring-shaped frames may be provided along the cap portions 22 and 32, respectively.

Further, in the above example, the ejection direction E of the nozzle was on the connecting ends B and C sides of the operating member 15 and the transmitting members 18 and 19.

More specifically, in the above example, when the contents are discharged forward (−Y side) through the tip portions 232 and 332 of the bent nozzles 23 and 33, the connecting end B of the operating member 15 is the front end (−Y side). The free end A, which is the end) and the point of effort, is the rear end (+ Y side end), the connecting end C of the plurality of transmission members 18 and 19 is the front end (-Y side end), and the working end D is the rear end. An example of an end (+ Y side end) has been described.

However, the bending direction of the nozzles 23 and 33 of the plurality of discharge containers 20 and 30 may be opposite as long as they do not collide with the standing member 12 and the operating member 15.

<Nozzle deformation example>
FIG. 19 shows a discharge amount adjusting device 1D according to a modified example of the nozzle of the present invention.
In this modification, the ejection direction of the nozzle is different from that of the embodiment shown in FIG. In this modification, the ejection direction F of the nozzle is on the free end A side and the working end D side of the operating member 15 and the transmitting members 18 and 19.

In other words, in FIG. 19, when the contents are discharged forward (+ Y side) through the tip portions 232D and 332D of the bent nozzles 23D and 33D, the connecting end B of the operating member 15 is the rear end (−Y side end). ), The free end A, which is the point of effort, is the front end (+ Y side end), and the connecting end C of the plurality of transmission members 18 and 19 is the rear end (-Y side end), which is the point of action. D is the front end (+ Y side end).

Even in the configuration of FIG. 19, the discharge direction F and the pivotal direction of the operating member 15 are in the same direction, and the operability of the user is improved without the tip portions 232D and 332D of the bent nozzles 23D and 32D colliding with the operating member 15. Can be secured.

Further, although FIG. 19 also shows an example in which the bending angles of the bending nozzles 23D and 33D are right angles, the bending of the bending nozzles 23D and 33D does not have to be right angles. The bending angle of the bending nozzles 23D and 33D may be at least a bending angle such that the tip portions 232D and 332D of the bending nozzles 23 and 33 do not collide with the surrounding portion 111 when pressed. Alternatively, the bending angles of the bending nozzles 23D and 33D may be adjustable in the elevation angle direction.

If both the configuration shown in FIG. 1 and the configuration shown in FIG. 19 can be applied, for example, when the contents are cosmetics having different colors, the directions of the tip portions 232 and 332 of the nozzles 23 and 33 (discharging direction). ) Can be changed to invert the discharge rate ratio. For example, by reversing the discharge amount ratio, it is advantageous for similar symmetrical makeup and drawing of graphic art.

In the present embodiment, when the cover 40 as shown in FIG. 15 is provided, the side surface of the operating member 15 in the same direction as the free end A and the portion where the nozzle comes out are opened.

Further, when ejecting contents that do not hang down, such as a mousse, the nozzles 23 and 33 may be configured by a straight nozzle that is not bent.

Further, in the above description, the nozzles 23 and 33 disclose a configuration in which both the base portion and the tip portion are thin, but the head portion of the base portion 231 has a larger diameter than the tip portion, for example, a pump head. It may be configured to be.

In any of the above embodiments, the amount can be adjusted by adjusting the fulcrum rod in the discharge amount adjusting mechanism of the present invention. Therefore, two or more contents can be discharged in an arbitrarily selected amount. Further, even if the pressing of the operating member 15 is stopped in the middle, the smaller amount of liquid can be discharged, and the discharge ratio does not change.

Although the above embodiment shows an example in which the contents are discharged in the form of drops, the discharge container may be pressurized in the nozzle and ejected in the form of mist.

Further, in the above example, although the container body is the bottomed bottle portions 21 and 31, the container body may be tube-shaped. Further, in the above example, although the bottle portion is a general bottle, the container body may be an airless bottle in which the inside of the bottle is evacuated by providing an insole piston inside the bottle. Alternatively, the container body is an airless bottle having a double structure that puts the inner bag in a vacuum state by providing a flexible inner bag that is detachably attached to the bottle, which is the outer container, inside the bottle. There may be. Such an airless container configuration is suitable for accommodating a liquid substance whose properties are likely to deteriorate or change when in contact with air.

Further, in the above-described embodiment and modified example, the discharge amount adjusting mechanism for adjusting the discharge amount of each of the two discharge containers has been described, but the discharge amount adjustment for adjusting the discharge amount of each of the three or more discharge containers has been described. The present invention is also applicable to the mechanism.

For example, in the case of a discharge amount adjusting mechanism that adjusts the discharge amount of each of three or more discharge containers, a plurality of fulcrum rods and transmission members are provided on either side surface side of the standing member and the operating member. Specifically, when three or more discharge containers are provided, one or one of the second discharge containers of the first discharge container that sandwiches the upright member is plural, and the plurality of first fulcrum rods and the plurality of first fulcrum rods are provided. One transmission member, or a plurality of second fulcrum rods and a plurality of second transmission members are provided.

Alternatively, in the case of a discharge amount adjusting mechanism that adjusts the discharge amount of each of the three or more discharge containers, three or more discharge containers are arranged on the same side surface side of the upright member, and three or more fulcrum rods corresponding to each are arranged. And 3 or more transmission members may be provided.

Further, in the above example, the liquid is shown as the content, but the content may be any liquid or fluid. For example, the viscosity of the liquid can be blended at 30 ° C. from 3000 mPa · s to 150,000 mPa · s. It is preferably 5000 mPa · s to 30000 mPa · s.
