Hereinafter, embodiments of the pump-type dispenser of the present disclosure will be exemplified with reference to the drawings.

In the present specification and claims, the vertical direction means the vertical direction in a state where the pump-type dispenser 1 is attached to the container 2 and is in an upright posture as shown in FIG. .. Further, the side where the nozzle opening 37g is provided is the front (right side in FIG. 1), and the opposite side is the rear (left side in FIG. 1). Further, the direction orthogonal to the vertical direction and the front-back direction (the direction perpendicular to the paper surface in FIG. 1) is defined as the lateral direction. Further, the radial direction means a direction along a straight line passing through the central axis O and perpendicular to the central axis O.

The pump-type dispenser 1 of the embodiment of the present disclosure shown in FIG. 1 is used as a pump-type dispenser by being attached to the mouth portion 2a of the container 2, and is housed in the storage space S of the container 2. Disinfectant such as alcohol and contents such as hand soap are poured out. As shown in FIGS. 1 and 2, the pump-type dispenser 1 has a mounting portion 10, a pump 20, a nozzle head 39, pressing members 37 and 38, a support member 31, and a guard member 34.

The mounting portion 10 is made of a synthetic resin material and is formed in a cylindrical shape with an inward flange 10a integrally provided at the upper end portion, and the female screw 10b provided on the inner peripheral surface is formed on the outer peripheral surface of the mouth portion 2a. By screwing to the male screw 2b provided on the container 2, the container 2 is detachably attached to the mouth portion 2a.

The pump 20 has a cylinder 21 having a cylindrical outer shape, a suction pipe 22 attached to the lower part of the cylinder 21, and a cylinder that protrudes upward from the upper end of the cylinder 21 and can be pushed down toward the inside of the cylinder 21. A shaped stem 23 and a piston 24 that is movably mounted inside the cylinder 21 and moves downward together with the stem 23 when the stem 23 is pushed down to discharge the contents inside the cylinder 21 from the upper end of the stem 23. It has a spring 26 that urges the stem 23 and the piston 24 upward via the piston guide 25, and a check valve 27 that opens and closes between the suction pipe 22 and the inside of the cylinder 21. In this embodiment, the stem 23 is arranged coaxially with the cylinder 21.

An annular flange 21a projecting outward in the radial direction is integrally provided on the upper portion of the cylinder 21. In the pump 20, the flange 21a is sandwiched between the packing 28 arranged at the upper end of the mouth portion 2a of the container 2 and the flange 10a of the mounting portion 10 screwed to the mouth portion 2a, whereby the container 2 is held. It is fixed to the mouth portion 2a and supported in a state of being suspended inside the container 2 through the mouth portion 2a.

The pump 20 is operated by pushing the stem 23 downward. That is, when the stem 23 is pushed downward, the piston 24 is pushed downward by the lower end of the stem 23, and the contents filled inside the cylinder 21 are discharged upward from the stem 23. The stem. On the other hand, when the pushing down of the stem 23 is released, the stem 23 and the piston 24 are pushed upward together with the piston guide 25 by the urging force of the spring 26 to return to the original position. When the piston 24 moves upward, the inside of the cylinder 21 becomes a negative pressure, the check valve 27 opens, and the contents contained in the container 2 are sucked into the inside of the cylinder 21 through the suction pipe 22.

A communication port 21b is provided on the side wall of the cylinder 21 at a position below the flange 21a, and the outer cylinder member 29 arranged outside the stem 23 is pressed by the rib 31c integrated with the stem 23. By moving the communication port 21b in the vertical direction with respect to the cylinder 21, the communication port 21b can be opened and closed. By providing the communication port 21b, when the inside of the container 2 becomes in a negative pressure state, outside air is taken in from the communication port 21b and the container 2 is restored.

The upper portion of the flange 21a of the cylinder 21 is a tubular body portion 21c that protrudes upward from the flange 10a of the mounting portion 10, and the adapter 40 is mounted on the tubular body portion 21c.

The adapter 40 has an annular stopper portion 41 that holds the flange 10a of the mounting portion 10 between the flange 21a and prevents the mounting portion 10 from coming off the pump 20. In the state where the mounting portion 10 is not mounted on the mouth portion 2a, the mounting portion 10 is rotatable with respect to the pump 20 in a state where the flange 10a is held between the flange 21a and the stopper portion 41. Thereby, the work of mounting the mounting portion 10 on the mouth portion 2a of the container 2 can be easily performed.

On the radial outer side of the upper end of the stem 23, the pressing member 37 (see FIGS. 7 and 9) in the bidirectional ejection mode (a state in which the contents can be ejected from both the first nozzle 39b and the second nozzle 39c) described later. A support member 31 that supports a part of the, 38 is integrally provided. As shown in FIG. 2, the support member 31 includes a top wall portion 31a having a substantially arcuate outline in a plan view, and a peripheral wall portion 31b hangs downward from the outer peripheral edge thereof. Further, inside the peripheral wall portion 31b in the radial direction, a held cylinder portion 36 that is coaxial with the peripheral wall portion 31b and hangs down from the lower surface of the top wall portion 31a is integrally provided. A female screw 36a is integrally provided on the inner peripheral surface of the held cylinder portion 36.

On the other hand, the adapter 40 is provided with a holding cylinder portion 42 protruding upward from the radial inside of the stopper portion 41, and a male screw 42a is integrally provided on the outer peripheral surface of the holding cylinder portion 42.

The support member 31 and the vertical cylinder 37e are connected to each other by pushing down the pressing members 37 and 38, which will be described later, to the lower stroke end and screwing the female screw 36a of the held cylinder portion 36 to the male screw 42a of the holding cylinder portion 42 of the adapter 40. The nozzle head 39 connected via the screw head 39 can be held in the pushed-down position. By holding the nozzle head 39 in the pushed-down position during distribution or the like, the pump-type dispenser 1 can be made compact and the volume of the container 2 to which the pump-type dispenser 1 is mounted can be reduced during distribution or the like. At the same time, it is possible to prevent the pressing members 37 and 38 from being accidentally pushed down and the contents being poured out during distribution or the like.

A vertical cylinder 37e integrally formed with the pressing members 37 and 38 is fitted to the inner peripheral surface of the upper end portion of the stem 23. As shown in FIG. 1, the vertical cylinder 37e forms an internal flow path N of the contents from the container 2 to the nozzle head 39 together with the mounting cylinder portion 39a of the stem 23 and the nozzle head 39. Further, the outer peripheral surface of the upper end portion of the vertical cylinder 37e is fitted to the inner peripheral surface of the mounting cylinder portion 39a of the nozzle head 39. With this configuration, the nozzle head 39 is fixed to the stem 23 of the pump 20 so as to move up and down integrally via the vertical cylinder 37e.

The nozzle head 39 is mounted on the upper end of the vertical cylinder 37e and extends in the vertical direction to form an internal flow path N of the contents, and the contents are forward from the upper end of the mounting cylinder 39a. It is provided with a first nozzle 39b for ejecting an object and a second nozzle 39c for ejecting the contents rearward from the upper end portion of the mounting cylinder portion 39a. As shown in FIG. 3, in a state where the pressing members 37 and 38 extend in the vertical direction and cover the nozzle head 39 from the front and the rear (unidirectional ejection mode), the first nozzle 39b oriented forward is the pressing member. It is exposed to the outside through the nozzle opening 37 g provided in 37. On the other hand, the second nozzle 39c oriented rearward is blocked by the blocking projection 38g provided on the pressing member 38. As a result, in the unidirectional ejection mode shown in FIG. 3, the contents pumped upward via the internal flow path N by the operation of the pump 20 are ejected from the first nozzle 39b and externally forward via the nozzle opening 37g. It is ejected to. On the other hand, since the second nozzle 39c is blocked by the obstruction projection 38g, the contents are not ejected to the rear. On the other hand, as shown by the solid line in FIG. 7, in the state where the pressing members 37 and 38 extend horizontally forward and backward (bidirectional ejection mode), the pump 20 operates upward via the internal flow path N. The pumped contents are ejected forward and backward from both the first nozzle 39b and the second nozzle 39c, respectively.

In the present embodiment, the nozzle head 39 is attached to the first nozzle 39b and the second nozzle 39c, respectively, in the flow paths oriented forward and backward from the upper end portion of the mounting cylinder portion 39a formed by injection molding of the synthetic resin material. Two corresponding nozzle tips are mounted.

The pressing members 37 and 38 include plate-shaped pressing plates 37a and 38a connected to the pressing flanges 37d and 38d protruding radially outward from the vertical cylinder 37e via hinge portions 37c and 38c. In the unidirectional ejection mode in which the pressing members 37 and 38 can be ejected only from the first nozzle 39b, the hinge portions 37c and 38c are bent by approximately 90 degrees as shown in FIG. 3, so that the pressing members 37 and 38 are bent along the nozzle head 39. It is oriented so as to extend in the vertical direction and covers the nozzle head 39 from the front and the rear.

The pressing plate 37a of the front pressing member 37 is formed with a nozzle cylinder 37f projecting forward in the unidirectional ejection mode shown in FIG. The nozzle cylinder 37f is provided at a position corresponding to the height position of the first nozzle 39b, and the internal space of the nozzle cylinder 37f is a nozzle opening 37g that exposes the first nozzle 39b to the outside. On the other hand, in the unidirectional ejection mode, a blocking protrusion 38g for closing the second nozzle 39c is provided on the surface of the pressing plate 38a of the rear pressing member 38 facing the nozzle head 39. The obstruction protrusion 38g is formed as a protrusion protruding toward the nozzle head 39 from a recess provided in the rear pressing plate 38a in the unidirectional ejection mode shown in FIG. With the above configuration, in the unidirectional ejection mode, the contents pumped upward via the internal flow path N by the operation of the pump 20 are ejected from the first nozzle 39b and ejected to the outside front through the nozzle opening 37g. To. On the other hand, since the second nozzle 39c is blocked by the obstruction projection 38g, the contents are not ejected to the rear.

Further, the pressing members 37 and 38 are provided with fitting portions 37b and 38b that project forward and backward, respectively, in the unidirectional ejection mode shown in FIG. The fitting portions 37b and 38b are pressed plates by fitting the radial outer surface of the support member 31 to the inner surface of the fitting portions 37b and 38b in the bidirectional ejection modes shown in FIGS. 7, 8 and 9. It plays a role of fixing 37a and 38a to the support member 31. Further, when the support member 31 is fitted to the fitting portions 37b and 38b, the pressing force applied when the pressing members 37 and 38 are pressed is dispersed and transmitted to the supporting member 31. Therefore, since it is possible to prevent the concentrated load from being directly applied to the hinge portions 37c and 38c, it is possible to suppress the breakage of the hinge portions 37c and 38c.

In the unidirectional ejection mode shown in FIG. 3, the upper end portions of the pressing members 37 and 38 extending in the vertical direction are pressing top portions 37h and 38h for operating the pump 20 by pressing. That is, when the user presses the pressing tops 37h and 38h with a thumb or the like, the pressing force is transmitted to the pressing flanges 37d and 38d and the vertical cylinder 37e via the hinge portions 37c and 38c, and the stem 23 into which the vertical cylinder 37e fits. Is pushed down to operate the pump 20. As shown in FIG. 3, the pressing tops 37h and 38h have a semicircular shape when viewed from the side, and even if the user presses with a thumb or the like, a concentrated load is unlikely to be applied.

Further, in the unidirectional ejection mode, engaging portions 37i and 38i for engaging the upper ends of the pressing plates 37a and 38a are provided at the upper ends of the pressing members 37 and 38. As shown in FIG. 3, the engaging portions 37i and 38i are formed so that the engaging portion 37i fits inside the engaging portion 38i in the unidirectional ejection mode, and the engaging portions 37i and 38i are formed on the engaging portions 37i and 38i. Each of the provided radial protrusions is configured to undercut and engage with each other. By providing the engaging portions 37i and 38i at the upper ends of the pressing members 37 and 38 in this way, the pressing members 37 and 38 are prevented from opening back and forth against the intention of the user in the unidirectional ejection mode. be able to. In the unidirectional ejection mode, when the user presses the pressing tops 37h and 38h, the engaging portions 37i and 38i come into contact with each other with a stronger force in the vertical direction, so that the engaging force in the engaging portions 37i and 38i is increased. Can be enhanced.

As shown in FIGS. 2, 4 and the like, guard members 34 are provided on both sides of the nozzle head 39 to prevent the user's hand from directly touching the first nozzle 39b and the second nozzle 39c. Has been done. The guard member 34 is a plate-shaped member arranged so as to cover the nozzle head 39 from the side. In the present embodiment, the outer shape of the guard member 34 is configured to substantially match the outer shape of the pressing members 37 and 38 in the side view in the unidirectional ejection mode. As shown in FIG. 4, relief openings 34a are provided in a grid pattern in the vertical direction and the front-rear direction along the central axis O at substantially the center position in the front-rear direction (horizontal direction in FIG. 4) of the guard member 34. The relief opening 34a is provided to release the ejection pressure of the contents from at least one of the first nozzle 39b and the second nozzle 39c. That is, even when the user excessively covers at least one of the first nozzle 39b and the second nozzle 39c by hand, the ejection pressure from the first nozzle 39b or the second nozzle 39c becomes too high and the contents are scattered. The ejection pressure can be released so as not to be released from the opening 34a to the outside. In the illustrated example, the relief openings 34a have a substantially square shape and are provided at equal intervals in the vertical direction and the front-back direction. The size, shape, number, and spacing of the relief openings 34a can be arbitrarily selected. Further, the relief opening 34a may not be provided.

Further, in the front edge portion and the trailing edge portion of the guard member 34, like the relief opening 34a, an opening recess for releasing the ejection pressure of the contents from at least one of the first nozzle 39b and the second nozzle 39c. 34b is provided. In the illustrated example, the opening recess 34b is a semicircular recess formed in the leading edge portion and the trailing edge portion of the guard member 34, and is vertically oriented along the leading edge portion and the trailing edge portion of the guard member 34. It is provided at four locations side by side at equal intervals. The size, shape, number, and spacing of the opening recesses 34b can be arbitrarily selected. Further, the opening recess 34b may or may not be provided in either the leading edge portion or the trailing edge portion.

As can be understood from FIGS. 4 and 9, the guard member 34 also has an effect of suppressing the nozzle head 39 from being exposed to the side.

When the pump-type dispenser 1 of the present embodiment having the above configuration is used in the unidirectional ejection mode, it is attached to the mouth portion 2a of the container 2 containing the contents, and the male screw 42a and the female screw 36a are engaged with each other. Is released, and the state of the unidirectional ejection mode shown in FIG. 3 is set. Then, when a pushing force is applied to the pressing tops 37h and 38h of the pressing members 37 and 38 with a thumb or the like, a downward force acts on the pressing plates 37a and 38a, so that the pressing flanges 37d pass through the hinge portions 37c and 38c. A pushing force also acts on the vertical cylinder 37e. As a result, the pressing flange 37d pushes down the upper end portion of the stem 23, so that the pump 20 operates and the contents contained in the container 2 are pumped upward via the internal flow path N. Then, the pumped contents are ejected from the first nozzle 39b in the horizontal direction forward, and are ejected toward the palm or the like via the nozzle opening 37 g (see FIG. 4). On the other hand, since the second nozzle 39c directed to the rear is blocked by the obstruction projection 38g, the contents are not ejected to the rear.

In this way, in the unidirectional ejection mode in which the pressing members 37 and 38 are oriented in the vertical direction, the user presses the pressing tops 37h and 38h with a thumb or the like to push the contents to one nozzle (first nozzle). It can be ejected from 39b) and supplied to the palm of the user or the like.

When the pressing operation of the pressing tops 37h and 38h is released, the pressing members 37 and 38 return to their original positions (positions shown in FIG. 3) together with the stem 23 by the urging force of the spring 26, and the contents contained in the container 2 are contained. Is sucked into the inside of the cylinder 21. Therefore, by repeating the pressing operation of the pressing tops 37h and 38h and the return to the original position, a desired amount of contents can be ejected from the first nozzle 39b and discharged to the outside from the nozzle opening 37g. ..

Next, use in a bidirectional ejection mode in which the contents can be ejected from both the first nozzle 39b and the second nozzle 39c will be described.

The user presses the guard member 34 radially inward (laterally inward) as shown in FIG. 6 from the state of the unidirectional ejection mode shown in FIG. As a result, the tapered portions 34c formed on the leading edge portion and the trailing edge portion of the guard member 34 push the pressing members 37 and 38 in the front-rear direction, so that the engaging portions 37i and 38i are as shown in FIGS. 5 and 6. Is disengaged. By this operation, the pressing members 37 and 38 can be rotated in the front-rear direction around the hinge portions 37c and 38c (the state of the alternate long and short dash line in FIG. 7). Then, by further opening in the direction of the arrow, the hinge portions 37c and 38c are not bent, and the portions of the pressing plates 37a and 38a closer to the center than the fitting portions 37b and 38b are on both sides of the hinge portions 37c and 38c. It abuts on and is supported on the upper surface of the top wall portion 31a of the support member 31, including the pressing flanges 37d and 38d. At this time, the pressing members 37 and 38 are in a state of extending horizontally toward the front and the rear (see FIGS. 7 and 8). Then, the pressing members 37 and 38 are fixed to the support member 31 by fitting the outer peripheral surface of the peripheral wall portion 31b of the support member 31 to the inner peripheral surfaces of the fitting portions 37b and 38b. As a result, the obstruction projection 38g is separated from the second nozzle 39c, so that the second nozzle 39c is exposed to the outside in addition to the first nozzle 39b (bidirectional ejection mode). As shown in FIGS. 7 and 8, on the pressing plates 37a and 38a, lightening 37j and 38j are provided in the area where the user presses with both hands. In the present embodiment, the lightening 37j and 38j are through holes having a substantially square shape, and are provided at equal intervals in the front-rear direction and the lateral direction. The size, shape, number, and spacing of the lightening 37j and 38j can be arbitrarily selected. Further, the lightening 37j and 38j may not be provided, or may be provided as a recess on the upper surface in the state of FIGS. 7 and 8.

After the transition to the bidirectional ejection mode is completed in FIG. 7, the user wraps the nozzle head 39 from the front-back direction with the palms of both hands as shown in FIG. Place it in the area of 37j and 38j. Then, the pressing plates 37a and 38a are pushed down by the sides of the little fingers of both hands downward as shown by the arrows in FIG.

When the pressing plates 37a and 38a are pushed down by the user, a downward pushing pressure is applied to the top wall portion 31a of the support member 31, and the stem 23 integrally formed with the support member 31 is also pushed down. As a result, the pump 20 operates and the contents contained in the container 2 are pumped upward via the internal flow path N. Then, the pumped contents are ejected horizontally forward from the first nozzle 39b and also ejected horizontally backward from the second nozzle 39c to push down the pressing plates 37a, 38a, etc. (See FIG. 9).

As described above, in the bidirectional ejection mode, the user can apply the contents in the container 2 to the palm or the like by pushing down the pressing plates 37a, 38a with the side portion of the little finger other than the palm, for example. Therefore, since it is not necessary to push down the pressing members 37 and 38 with the palm of the hand, it is possible to prevent the user from feeling uncomfortable with the pushing down operation of the pressing members 37 and 38. Further, in the present embodiment, since the area provided with the lightening 37j, 38j on the pressing plates 37a, 38a is pressed, the contact area between the user's hand and the pressing plates 37a, 38a can be reduced. can.

FIG. 10 is a modified example of the pump-type dispenser 1 according to the present embodiment. In this modification, a foaming member 50 for foaming the contents is arranged in the nozzle opening 37 g. With such a configuration, in the unidirectional ejection mode, the contents ejected from the first nozzle 39b can be foamed and then ejected to the outside.

As described above, the pump-type dispenser 1 according to the present embodiment includes a mounting portion 10 mounted on the mouth portion 2a of the container 2, a pump 20 fixed to the container 2 by the mounting portion 10, and a pump 20. A nozzle head 39 having a first nozzle 39b that is connected to the stem 23 and can be ejected substantially forward and a second nozzle 39c that can be ejected substantially rearward, and a nozzle head 39 that is connected to the stem 23 via hinge portions 37c and 38c. In a unidirectional ejection mode in which the contents can be ejected only from one nozzle 39b, a plurality of pressing members 37, 38 extending upward to cover the nozzle head 39 from the front and the rear are provided, and among the plurality of pressing members 37, 38. The pressing member 37 on the front side has a nozzle opening 37g that exposes the first nozzle 39b to the outside in the unidirectional ejection mode, and the bidirectional ejection mode in which the contents can be ejected from both the first nozzle 39b and the second nozzle 39c. In, the plurality of pressing members 37 and 38 are configured to extend substantially forward and substantially backward and to push down the stem 23 by receiving a downward pushing force. By adopting such a configuration, the contents can be ejected in two ejection modes, a unidirectional ejection mode and a bidirectional ejection mode. Then, in the bidirectional ejection mode, the contents can be evenly supplied to both hands by one ejection operation. If it is difficult to receive the contents with both hands, it is possible to switch to the unidirectional ejection mode and receive the contents with one hand. Further, since the user can push down the pressing members 37 and 38 at a portion other than the palm, the user can use the contents relatively hygienically, and the operation of pressing the pressing members 37 and 38 can be performed. You can avoid feeling uncomfortable. In the present embodiment, since the pressing members 37 and 38 can be closed, the volume of the pump-type dispenser 1 at the time of distribution can be reduced.

Further, in the present embodiment, the plurality of pressing members 37, 38 are configured to have engaging portions 37i, 38i that engage the upper end portions with each other in the unidirectional ejection mode. By adopting such a configuration, it is possible to prevent the plurality of pressing members 37, 38 from opening in the front-rear direction against the intention of the user and shifting to the bidirectional ejection mode in the unidirectional ejection mode.

Further, in the present embodiment, a guard member 34 that covers the nozzle head 39 from the side is further provided, and the guard member 34 releases the ejection pressure of the contents ejected from at least one of the first nozzle 39b and the second nozzle 39c. It was configured to have a relief opening 34a. By adopting such a configuration, even if the user excessively covers at least one of the first nozzle 39b and the second nozzle 39c by hand, the ejection pressure from the first nozzle 39b or the second nozzle 39c becomes high. The ejection pressure can be released and opened to the outside from the opening 34a so that the contents do not scatter past.

Further, in the present embodiment, a guard member 34 that covers the nozzle head 39 from the side is further provided, and the guard member 34 has at least one of the first nozzle 39b and the second nozzle 39c on at least one of the leading edge portion and the trailing edge portion. It is configured to have an opening recess 34b that releases the ejection pressure of the contents ejected from. By adopting such a configuration, even if the user excessively covers at least one of the first nozzle 39b and the second nozzle 39c by hand, the ejection pressure from the first nozzle 39b or the second nozzle 39c becomes high. The ejection pressure can be released to the outside from the opening recess 34b so that the contents do not scatter too much.

Further, in the present embodiment, in the bidirectional ejection mode, the support member 31 that supports at least a part of the plurality of pressing members 37, 38 from below is further provided. By adopting such a configuration, it is possible to instruct the support member 31 to extend the pressing members 37 and 38 in the substantially horizontal direction, so that it is possible to suppress excessive stress from being applied to the hinge portions 37c and 38c. ..

Further, in the present embodiment, the plurality of pressing members 37, 38 include fitting portions 37b, 38b projecting substantially forward and substantially rearward in the unidirectional ejection mode, and the fitting portions 37b, 38b in the bidirectional ejection mode. The pressing members 37, 38 are configured to be fixed to the supporting member 31 by fitting the outer peripheral surface of the supporting member 31 that supports at least a part of the plurality of pressing members 37, 38 from below. By adopting such a configuration, it is possible to maintain the plurality of pressing members 37, 38 in the bidirectional ejection mode with a simple configuration, so that it is possible to suppress the switching of the ejection mode unintentionally by the user. Further, when the support member 31 is fitted to the fitting portions 37b and 38b, the pressing force applied when the pressing members 37 and 38 are pressed is dispersed and transmitted to the supporting member 31. Therefore, since it is possible to prevent the concentrated load from being directly applied to the hinge portions 37c and 38c, it is possible to suppress the breakage of the hinge portions 37c and 38c.

Further, in the present embodiment, the foaming member 50 for foaming the contents ejected from the first nozzle 39b is arranged in the nozzle opening 37g. By adopting such a configuration, in the unidirectional ejection mode, the contents ejected from the first nozzle 39b can be foamed and then ejected to the outside.

Although the present disclosure has been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various modifications and corrections based on the present disclosure. Therefore, it should be noted that these modifications and modifications are included in the scope of the present invention. For example, the functions included in each component can be rearranged so as not to be logically inconsistent, and a plurality of components can be combined or divided into one. It should be understood that these are also included in the scope of the present invention.

For example, in the present embodiment, the pressing members 37, 38 are integrally formed with the pressing flanges 37d, 38d and the vertical cylinder 37e via the hinge portions 37c, 38c, so that the vertical cylinder 37e is further fitted and fixed to the stem 23. However, the present invention is not limited to this aspect. The pressing members 37 and 38 may be integrally formed with the stem 23 via the hinge portions 37c and 38c. Further, the pressing members 37 and 38 may be integrally formed with members other than the pressing flanges 37d and 38d and the vertical cylinder 37e.

Further, in the present embodiment, the first nozzle 39b is oriented so that the contents can be ejected horizontally forward, and the second nozzle 39c is configured so that the contents can be ejected horizontally backwards. However, the ejection direction does not have to be strictly forward and backward, and may be inclined downward, for example, with respect to the front and rear.

Further, in the present embodiment, the outer shape of the guard member 34 is configured to substantially match the outer shape of the pressing members 37 and 38 in the side view in the unidirectional ejection mode, but the present invention is not limited to this embodiment. The guard member 34 may be provided so as to project in the front-rear direction from the first nozzle 39b and the second nozzle 39c so that the user's hand does not directly touch the first nozzle 39b and the second nozzle 39c.

Further, in the present embodiment, a modified example is shown in which the foaming member 50 is arranged in the nozzle opening 37g to foam the contents ejected from the first nozzle 39b, but the foaming member 50 is ejected from the second nozzle 39c. The contents may be arranged so as to foam.

Further, in the present embodiment, it is assumed that a disinfectant solution such as alcohol or a hand soap is stored in the container 2 as the contents, but other contents such as cosmetics to be discharged and used in the palm are stored. You may try to do it.

Further, the pump 20 is not limited to the above-described configuration, and any other configuration may be adopted as long as it operates by pushing down the stem 23.
