SUMMARY OF THE INVENTION An object of one aspect of the present invention is to provide a discharge container that can improve convenience for the user.

One aspect of the discharge container of the present invention comprises a container body in which contents are contained, a dispenser having a stem erected at the mouth of the container body so as to be movable downward in an upward biased state, and the stem. an exterior body having a top wall portion formed with a discharge hole extending vertically through the stem and disposed above the stem; and an exterior body disposed above the stem inside the exterior body, a middle plate that is vertically movable with respect to the exterior body; When the stem is pushed downward by the middle plate, the discharge hole extends through the space between the top wall portion and the middle plate to the upwardly facing discharge surface of the top wall portion. The operation member is formed with a pair of pressing portions arranged on both sides of the rotation shaft in plan view along the vertical direction, and the exterior body is formed with a plane along the vertical direction A pair of engaging protrusions are formed on each of the pair of pressing portions so as to be engaged from above, and the operating member has a shape that surrounds the outer side in the radial direction of the exterior body. wherein the middle plate includes a pair of support projections projecting radially outward along the rotation shaft, the pair of support projections penetrating the peripheral wall portion of the exterior body in the radial direction and The member includes a pair of connecting portions rotatably disposed on each of the pair of support projections, and the engaging projections are formed on the outer peripheral surface of the exterior body .

According to one aspect of the discharge container of the present invention, the operation member is formed with a pair of push-down portions arranged on both sides of the rotation shaft in plan view along the vertical direction, and the exterior body is formed with a pair of push-down portions. A pair of engaging protrusions that can be engaged from above are formed on each of the portions. Therefore, when one of the pair of push-down portions is pushed down, the other push-down portion engages with the engagement projection, and the operation member rotates around the rotation axis as the operation member rotates around the rotation axis. The part attached to the middle plate can be pushed down freely. As a result, the stem can be pushed down by moving the middle plate downward, and the contents can be discharged from the discharge hole through the space between the top wall portion and the middle plate. In other words, the user can eject the contents by pressing down only one of the pair of pressing portions arranged on both sides of the rotation shaft in plan view along the vertical direction. Therefore, the user can operate the discharge container by depressing the pressing portion from either side of the direction sandwiching the rotation shaft in a plan view along the vertical direction, and the contents can be discharged. can be done. As described above, according to one aspect of the discharge container of the present invention, user convenience can be improved.

In addition, when pushing down the push-down portion, it is necessary to push down the push-down portion against, for example, a biasing means or the like that biases the stem upward. Therefore, the force required to push down the pressing portion may increase. On the other hand, according to one aspect of the discharge container of the present invention, when one of the pressing portions is pressed down, the operating member rotates with the engagement portion of the other pressing portion with the engaging protrusion acting as a fulcrum. move. Therefore, the position of engagement with the engaging projection on the other pressing portion is used as a fulcrum, the position where force is applied to one of the pressing portions is used as a force point, and the portion of the operation member connected to the inner plate is used as an action point. Using the principle of leverage, the middle plate can be pushed down while pushing down one of the push-down portions. As a result, the force required to push down the pressing portion can be reduced, and the discharge operation can be easily performed. Therefore, user convenience can be further improved.

Further, by using the principle of leverage as described above, it is possible to increase the amount of depression of the pressing portion with respect to the amount of movement of the inner plate. Therefore, by adjusting the amount of depression of the depression portion, it is easy to finely adjust the amount of downward movement of the inner tray. This makes it easy to finely adjust the amount of depression of the stem that is pushed down by the inner plate, and easily adjust the discharge amount of the contents. Therefore, according to one aspect of the discharge container of the present invention, the amount of content to be taken out can be adjusted favorably. Therefore, user convenience can be further improved.

Moreover, according to one aspect of the discharge container of the present invention, it is also possible to simultaneously push down both of the pair of push-down portions to discharge the contents. In this case, the amount of downward movement of the inner plate can be increased compared to when only one of the pair of pressing portions is pressed. This makes it possible to increase the amount by which the stem is pushed down, thereby increasing the amount of content discharged from the stem. Therefore, the user can adjust the discharge amount of the contents by selecting whether to press down only one of the pair of pressing portions or to press both of them at the same time. Therefore, user convenience can be further improved.

The operating member has a shape that surrounds the radially outer side of the exterior body, and the inner plate includes a pair of supporting projections that protrude radially outwardly along the rotation shaft, and the pair of supporting projections: The operating member includes a pair of connecting portions rotatably disposed on each of the pair of support projections, the operation member radially penetrating through the peripheral wall portion of the exterior body, and the engagement projection is connected to the exterior body. may be formed on the outer peripheral surface of the

According to this configuration, the content can be discharged by rotating the operating member while suppressing the operating member from protruding in the vertical direction from the exterior body. As a result, the size of the discharge container can be reduced in the vertical direction. In addition, since the operation member has a shape surrounding the outer side in the radial direction of the exterior body, it is easy to provide a large depressing portion, and the depressing portion can be easily depressed with a finger or the like.

According to one aspect of the present invention, a discharge container is provided that can improve user convenience.

More specifically, the radial inner end portions of the pair of engaging portions 53c are positioned below the circumferential end portions of the engaging protrusions 35, respectively. Thereby, the engaging portion 53c can be engaged with the engaging projection 35 from below. In other words, the pair of engaging projections 35 can be engaged with the pair of pressing portions 53 from above.

The pair of connection portions 52 protrude from the operation member main body 51 on both sides in the rotation axis direction (Y-axis direction). The pair of connecting portions 52 are arranged to sandwich the container axis O in the rotation axis direction (Y-axis direction). As shown in FIG. 3, the pair of connection portions 52 are arranged on the rotation axis R. As shown in FIG. A radially inner surface of the connecting portion 52 is formed with a concave portion 52a that is recessed radially outward. Portions of the pair of support projections 47 that protrude radially outward from the forming member 30 are fitted into the recesses 52 a of the pair of connection portions 52 , respectively. The support projection 47 supports the connection portion 52 so as to be rotatable around the rotation axis R. As shown in FIG. As a result, the pair of connection portions 52 are rotatably disposed on the pair of support projections 47, respectively, and the operation member 50 is rotatably disposed on the inner plate 40 about the rotation axis R. .

The cap 70 is a capped cylindrical member. The cap 70 has a cylindrical shape that opens downward and is arranged coaxially with the axis O of the container. The cap 70 is detachably fitted and attached to the container body 11 . The cap 70 covers the top and radial outside of the shaping head 10 .

A user who uses the discharge container 1 first removes the cap 70 . Next, as shown in FIG. 4, the user applies downward force to one of the pair of pressing portions 53 with a finger or the like. At this time, the user applies downward force to the pressing portion 53 by, for example, hooking the finger on the pressing portion main body 53b. When a downward force is applied to one of the pressing portions 53, the operating member 50 as a whole rotates around the rotation axis R. As shown in FIG. In the example of FIG. 4, the operation member 50 rotates counterclockwise about the rotation axis R when viewed from the negative side (-Y side) of the rotation axis direction.

At this time, one pressed portion 53 moves downward, and the other pressed portion 53 attempts to move upward. However, since the engaging projection 35 is engaged with the engaging portion 53c of the other pressing portion 53 from above, the upward movement of the other pressing portion 53 is restricted. As a result, the operating member 50 rotates about the rotation axis R while the vertical position of the other pressing portion 53 remains substantially unchanged. It rotates with the engagement point between the portion 53c and the engagement projection 35 as a fulcrum. Therefore, the portion of the operating member 50 positioned closer to one of the depressed portions 53 (-X side) than the engaging portion serving as the fulcrum moves downward as a whole, and is attached to the inner tray 40. The connecting portion 52 also moves downward. Therefore, as the operation member 50 rotates and moves downward, the inner tray 40 moves downward. At this time, the support projections 47 of the inner plate 40 move downward along the through holes 32a.

When the middle plate 40 moves downward as the pressing portion 53 is pushed down, the upper end portion of the stem 13 b is inserted into the lower end portion of the central cylindrical portion 42 . When the inner plate 40 moves further downward, the upper end of the stem 13b comes into contact with the lower end of the rib portion 45. As shown in FIG. Further downward movement of the inner plate 40 in this state moves the stem 13b downward. As a result, the content C is discharged from the upper end opening 14 of the stem 13b. The discharged content C flows into the diffusion chamber 80 through the communication hole 48 .

The content C that has flowed into the diffusion chamber 80 flows vertically on the outer peripheral surface of the core 33 and is held by the core 33 . At this time, the content C is held by the core body 33 so as to form a circular shape centering on the core body 33 in plan view, for example. As the amount of the content C discharged from the stem 13b increases and the amount of content supplied to the core 33 increases, the content C grows on the core 33 and gradually expands outward in the radial direction. Inflate. As a result, the content C supplied into the diffusion chamber 80 is diffused in the radial direction, coupled with the fact that the diffusion chamber 80 is formed in a flat shape as described above. The contents C diffused in the diffusion chamber 80 are supplied to the plurality of forming holes 34 from the supply surface 31b. The contents C that have flowed into the plurality of molding holes 34 pass through the molding holes 34, are molded into modeling pieces, and are discharged onto the modeling surface 31a. In this way, the stem 13b of the discharger 13 is pushed downward by the middle plate 40, so that the top wall portion 31 is displaced through the diffusion chamber 80, which is the space between the top wall portion 31 and the middle plate 40. The content C is discharged from the molding hole 34, which is a discharge hole, onto the molding surface 31a, which is a discharge surface facing upward. A modeled object is formed on the modeling surface 31a by combining the modeling pieces ejected from the plurality of molding holes 34 respectively. In this embodiment, the shape of the modeled object is, for example, a flower-like shape in which the petals overlap.

After that, when the pressing operation of the pressing portion 53 is released, the restoring force of the biasing member 60 and the restoring force of the biasing means (not shown) biasing the stem 13b move the inner plate 40 upward, and the operation member 50 rotates in a direction opposite to that during the push-down operation. As the middle plate 40 moves upward, the internal volume of the diffusion chamber 80 decreases or disappears, and the content C remaining in the diffusion chamber 80 is discharged from the diffusion chamber 80 through the molding holes 34 to the forming surface 31a. . The user can use the ejected content C by picking up the ejected content C as a modeled object on the modeling surface 31a with a finger or the like.

According to the present embodiment, the operating member 50 is formed with a pair of push-down portions 53 arranged across the rotation axis R in a plan view along the vertical direction, and the exterior body 10b is provided with the pair of push-down portions 53. are formed with a pair of engaging protrusions 35 that can be engaged from above. Therefore, when one of the pair of push-down portions 53 is pushed down as described above, the other push-down portion 53 engages with the engagement projection 35, and as the operation member 50 rotates about the rotation axis R, The connection portion 52 of the operation member 50, which is rotatably arranged on the inner plate 40 about the rotation axis R, can be pushed down. As a result, the middle plate 40 can be moved downward to push down the stem 13b, and the contents C can be taken out as a modeled object from the forming hole 34 via the diffusion chamber 80. As shown in FIG. That is, the user pushes down only one of the pair of pressing portions 53 arranged on both sides of the rotation axis R in plan view along the vertical direction, thereby ejecting the content C and taking it out as a modeled object. is possible. Therefore, the user can operate the discharge container 1 by depressing the pressing portion 53 from either direction (width direction, X-axis direction) sandwiching the rotation axis R in plan view along the vertical direction. and the content C can be discharged. As described above, according to the present embodiment, user convenience can be improved.

When pressing down the pressing portion 53, it is necessary to press down the pressing portion 53 against the biasing member 60 that biases the inner plate 40 upward and the biasing means (not shown) that biases the stem 13b upward. be. Therefore, the force required to push down the pressing portion 53 tends to increase. On the other hand, according to the present embodiment, when one of the pressing portions 53 is pressed down, the operating member 50 rotates around the engagement portion of the other pressing portion 53 with the engaging projection 35 as a fulcrum. . Therefore, the position of engagement with the engaging projection 35 in the other pressing portion 53 is used as a fulcrum, the position where force is applied to the one pressing portion 53 is used as a force point, and the portion of the operation member 50 connected to the inner tray 40 is used as a fulcrum. Using the principle of leverage as a point of action, it is possible to push down the inner plate 40 while pushing down the pressing portion 53 on one side. As a result, the force required to push down the pressing portion 53 can be reduced, and the ejection operation can be easily performed. Therefore, user convenience can be further improved.

In this embodiment, it is possible to push down the pressing portion 53 with approximately half the force required to directly move the inner plate 40 downward. At this time, the amount by which the pressing portion 53 is pushed down in the vertical direction is approximately twice the amount by which the inner tray 40 moves downward. In this manner, since the amount of depression of the pressing portion 53 can be increased with respect to the amount of movement of the inner tray 40, by adjusting the amount of depression of the pressing portion 53, the amount of downward movement of the inner tray 40 can be finely adjusted. Easy to adjust. As a result, it is easy to finely adjust the amount of depression of the stem 13b that is pushed down by the middle plate 40, and the discharge amount of the contents C can be easily adjusted. Therefore, according to this embodiment, the amount of the content C to be taken out can be suitably adjusted. Therefore, user convenience can be further improved.

Further, in the above description, an example of pressing down only one of the pair of pressing portions 53 has been described. However, according to the present embodiment, both of the pair of pressing portions 53 are simultaneously pressed to discharge the contents C. is also possible. In this case, the amount of downward movement of the inner tray 40 can be increased compared to when only one of the pair of pressing portions 53 is pressed. As a result, the amount by which the stem 13b is pushed down can be increased, and the amount of the content C discharged from the stem 13b can be increased. Therefore, the user can also adjust the discharge amount of the content C by selecting whether to push down only one of the pair of push-down portions 53 or both at the same time. Therefore, user convenience can be further improved.

Further, according to the present embodiment, the operating member 50 has a shape surrounding the outer side in the radial direction of the exterior body 10b, and the engaging projection 35 is formed on the outer peripheral surface of the exterior body 10b. Therefore, it is possible to rotate the operating member 50 to discharge the contents C while suppressing the vertical protrusion of the operating member 50 from the exterior body 10b. Thereby, the dimension of the shaping head 10 in the vertical direction can be reduced, and the discharge container 1 can be miniaturized in the vertical direction. Further, since the operation member 50 has a shape that surrounds the outer side of the exterior body 10b in the radial direction, it is easy to provide a large push-down portion 53, and the push-down portion 53 can be easily pushed down with a finger or the like.

In addition, in the embodiment described above, the following configuration can also be adopted.
The shape of the modeled object of the content C is not particularly limited. When the shape of the modeled object is the shape of a flower, it may be, for example, a sunflower, a cherry blossom, or the like. The shape of the modeled object may be a shape other than a flower, and may be a shape such as a letter or a logotype. The shape of the molded object can be changed by appropriately changing the number and shape of the molding holes 34 . The number and shape of the forming holes 34 may be appropriately changed depending on the purpose of the content C to be discharged. Moreover, the content C discharged from the discharge container 1 does not have to be a modeled object. In this case, the discharge hole formed in the top wall portion 31 may not be the molding hole 34 .

The operation member 50 is not particularly limited as long as it is arranged on the inner plate 40 so as to be rotatable around the rotation axis R. The operation member 50 may be arranged at a position shifted in the vertical direction with respect to the exterior body 10b. The operation member 50 may not have a shape surrounding the exterior body 10b, and may be provided only on one side of the exterior body 10b in the rotation axis direction (Y-axis direction), for example.

The engagement projection 35 is not particularly limited as long as it is formed on the exterior body 10b. For example, when the operation member 50 is arranged below the exterior body 10b, the engagement projection 35 may be formed on the fixing member 20. As shown in FIG. The engaging projections 35 may be formed on a separate member attached to the fixing member 20 or the shaping member 30 .

Further, as shown in FIG. 5, the inner plate 140 and the operating member 150 may be integrally formed. The middle plate 140 and the operating member 150 are integrally formed by injection molding or the like. An operation member body 151 of the operation member 150 has curved portions 151a that curve downward at both ends in the rotation axis direction (Y-axis direction). The curved portion 151 a connects the portions of the operation member main body 151 that are positioned on both sides of the support projection 147 of the inner plate 140 in the circumferential direction, and is positioned below the support projection 147 . A connection portion 152 that connects the curved portion 151a and the support projection 147 is formed in the circumferential central portion of the curved portion 151a. In the configuration of FIG. 5, the rotation axis R passes through the connecting portion 152. As shown in FIG. The connection portion 152 is a hinge portion, and is elastically deformed around the rotation axis R when one of the pressing portions 53 is pushed down. As a result, the operation member 150 can rotate about the rotation axis R with respect to the inner tray 140 .
It should be noted that the configurations described in this specification can be appropriately combined within a mutually consistent range.
