The side to which the arrow of the X-axis points in the first direction D1 (+X side) is the front side of the ejection device. The side opposite to the side to which the arrow of the X-axis points in the first direction D1 (-X side) is the back side of the ejection device. In the following description, the front side of the ejection device is simply referred to as the "front side", and the back side of the ejection device is simply referred to as the "back side".
[0012] In each drawing, the Y-axis is shown as appropriate. In the present embodiment, the direction in which the Y-axis extends is the second direction D2. The second direction D2 is perpendicular to both the vertical direction and the first direction D1.
[0013] FIG. 1 is a side view showing the ejection device 10 of the present embodiment. FIG. 2 is a front view showing the ejection device 10 of the present embodiment. FIG. 3 is a perspective view showing a part of the ejection device 10 of the present embodiment. FIG. 4 is a first side view showing a part of the ejection device 10 of the present embodiment. FIG. 5 is a second side view showing a part of the ejection device 10 of the present embodiment. As shown in FIG. 1, the ejection device 10 of the present embodiment includes a container body 20, a mounting cap 25, and a pump device 30.
[0014] The container body 20 accommodates the contents. The contents are not particularly limited and are preferably liquids such as hand soap, body soap, facial cleanser, shampoo, hair styling agent, and kitchen detergent, and liquids that can be discharged in a foamy state. As the material of the container body 20, synthetic resin materials such as polyethylene resin (PE), polypropylene resin (PP), polyester resin (PEs), and polyethylene terephthalate resin (PET) can be used. The container body 20 has a storage portion 21 and a mouth portion 22.
[0015] The storage portion 21 is cylindrical and extends in the vertical direction. In the present embodiment, the storage portion 21 is substantially cylindrical with the container axis J1 as the center. The contents are stored inside the storage portion 21.
[0016] The mouth portion 22 is cylindrical and extends upward from the container body 20. In the present embodiment, the mouth portion 22 is substantially cylindrical with the container axis J1 as the center. The mouth portion 22 opens upward. A male screw portion (not shown) is provided on the outer peripheral surface of the mouth portion 22.
[0017] The mounting cap 25 is cylindrical and protrudes in the vertical direction. In the present embodiment, the mounting cap 25 is substantially cylindrical with the container axis J1 as the center. A female screw portion (not shown) is provided on the inner peripheral surface of the mounting cap 25. When the female screw portion of the mounting cap 25 is screwed onto the male screw portion of the mouth portion 22, the mounting cap 25 is mounted on the mouth portion 22. Thereby, the mounting cap 25 is mounted on the container body 20.
[0018] The pump device 30 sucks up and discharges the contents stored in the container body 20. In the present embodiment, the pump device 30 sucks up the contents stored in the container body 20 and discharges them in a foamy state. The pump device 30 may discharge the contents in a liquid state. The pump device 30 is attached to the container body 20 via the mounting cap 25. The pump device 30 has a cylindrical portion 31, a head portion 32, a nozzle portion 33, a support member 34, and a lever portion 36.
[0019] The cylindrical portion 31 is cylindrical and extends upward from the mounting cap 25. In the present embodiment, the cylindrical portion 31 is substantially cylindrical about the container axis J1. The inside of the cylindrical portion 31 is connected to the inside of the storage portion 21 via the mounting cap 25 and the mouth portion 22.
[0020] The head portion 32 is attached to the upper part of the cylindrical portion 31. The head portion 32 is movable in the vertical direction while being biased upward by a spring (not shown). The head portion 32 is cylindrical and extends in the vertical direction. In the present embodiment, the head portion 32 is substantially cylindrical about the container axis J1.
[0021] The nozzle portion 33 is cylindrical and extends from the upper portion of the head portion 32 toward the front side (+X side). In the present embodiment, the front end of the nozzle portion 33 is substantially at the same position as the front end of the container body 20. The nozzle portion 33 has a discharge port 33a. The discharge port 33a is provided at the front end of the nozzle portion 33 and is an opening that opens to the front side. In the present embodiment, the nozzle portion 33 is integrated with the head portion 32. The nozzle portion 33 and the head portion 32 may be different members. The pump device 30 discharges the content stored in the storage portion 21 in a foamed state from the discharge port 33a of the nozzle portion 33 when the head portion 32 is pushed down.
[0022] The support member 34 extends in a direction between the upper side and the back side (-X side) from the cylindrical portion 31. In the present embodiment, the support member 34 is integrated with the cylindrical portion 31. The lower end of the support member 34 is connected to the back side portion of the outer peripheral surface of the cylindrical portion 31. The support member 34 is located upward as it goes toward the back side. The upper end of the support member 34 is located on the front side (+X side) of the back side end of the storage portion 21. The upper end of the support member 34 may be located on the back side of the back side end of the storage portion 21. As shown in FIG. 4, the support member 34 has a support surface 34b.
[0023] The support surface 34b is a surface provided at the upper end of the support member 34 among the outer surfaces of the support member 34. In the present embodiment, the support surface 34b faces upward. The support surface 34b is located inside the lever portion 36. The support surface 34b faces the lever portion 36 in the vertical direction.
[0024] The lever portion 36 shown in FIG. 1 is a member that pushes down the head portion 32 by the operation of a user. The lever portion 36 extends from the upper end of the support member 34 toward the front side (+X side). In the present embodiment, a second distance L2, which is the distance between the container axis J1 and the end portion on the back side (-X side) of the container body 20, is equal to or greater than a first distance L1, which is the distance between the container axis J1 and the end portion on the back side of the lever portion 36. The end portion on the front side of the lever portion 36 is located on the front side of the nozzle portion 33 and the container body 20. The lever portion 36 has a first lever portion 37, a second lever portion 38, and a connecting portion 36a.
[0025] The first lever portion 37 extends from the upper end of the support member 34 toward the front side (+X side). The end portion on the back side (-X side) of the first lever portion 37 is attached to the upper end of the support member 34. As shown in FIG. 3, more specifically, the first lever portion 37 is attached to the support member 34 by passing a pin 51 in a second direction D2 through both a hole provided in the end portion on the back side of the first lever portion 37 and a hole provided in the upper end of the support member 34. The pin 51 is columnar with a rotation axis J2 extending in the second direction D2 as the center. Thereby, the lever portion 36 is attached to the support member 34 so as to be rotatable about the rotation axis J2. Thereby, the lever portion 36 is attached to the support member 34 so as to be rotatable in the vertical direction about the rotation axis J2. Note that the rotation axis J2 is a virtual axis.
[0026] As shown in FIG. 1, when viewed from the second direction D2, the first lever portion 37 has a curved shape that bulges upward. The first lever portion 37 extends from the upper end of the support member 34 toward the front side (+X side) above the head portion 32, and then extends in a direction inclined downward from the front side. Therefore, a part of the first lever portion 37 is disposed above the head portion 32. Thus, when the lever portion 36 is rotated downward by a user, a part of the first lever portion 37 comes into contact with the head portion 32 in the vertical direction and pushes down the head portion 32. As a result, the content accommodated in the accommodating portion 21 is discharged from the discharge port 33a of the nozzle portion 33. The front-side end of the first lever portion 37 is located on the front side of the nozzle portion 33 and the container body 20 and below the nozzle portion 33. As shown in FIG. 2, an opening 37a is provided in the first lever portion 37. Further, as shown in FIG. 4, the first lever portion 37 has a rotation restricting portion 36c.
[0027] As shown in FIG. 2, the opening 37a is a hole that penetrates the first lever portion 37 substantially in the vertical direction. The opening 37a has a substantially rectangular shape with a long side extending along the extending direction of the first lever portion 37. As shown in FIG. 1, the rear-side (-X side) end of the opening 37a is located on the front side (+X side) of the container axis J1. Thereby, when the user rotates the lever portion 36 downward, the head portion 32 can be pushed down by the first lever portion 37. The front-side end of the opening 37a is located on the front side of the nozzle portion 33 and below the nozzle portion 33. The nozzle portion 33 passes through the opening 37a. Therefore, the content discharged from the discharge port 33a toward the front side is discharged to the front side of the lever portion 36 through the opening 37a.
[0028] As shown in FIG. 3, the rotation restricting portion 36c is a surface provided at the rear-side (-X side) end of the lever portion 36. As shown in FIG. 4, the rotation restricting portion 36c faces in a direction inclined from the lower side to the rear side. As shown in FIG. 5, when the lever portion 36 rotates upward by an allowable angle α, the rotation restricting portion 36c comes into contact with the support surface 34b of the support member 34 in the vertical direction. Thereby, the lever portion 36 can be prevented from rotating upward more than the allowable angle α.
[0029] The second lever portion 38 shown in FIG. 1 is connected to the end portion on the front side (+X side) of the first lever portion 37. The second lever portion 38 is disposed on the front side of each of the nozzle portion 33 and the container body 20 and below the nozzle portion 33. When viewed from the second direction D2, the second lever portion 38 has a substantially V-shaped opening in the direction facing between the front side and the upper side. The second lever portion 38 has a first portion 38a and a second portion 38b.
[0030] The first portion 38a extends between the lower side and the front side (+X side). The upper end of the first portion 38a is connected to the end portion on the front side of the first lever portion 37. The first portion 38a is located on the front side as it goes toward the lower side. The first portion 38a has a first operation surface 38d. The first operation surface 38d is a surface facing between the upper side and the front side among the outer surfaces of the first portion 38a. When the user presses the first operation surface 38d in the direction facing between the lower side and the back side (-X side), the lever portion 36 rotates downward. Thereby, the head portion 32 can be pushed down by the first lever portion 37, so that the content can be discharged from the discharge port 33a of the nozzle portion 33.
[0031] The second portion 38b extends toward the front side (+X side). That is, the second portion 38b extends toward the front side rather than in the direction in which the first portion 38a extends. If the second portion 38b extends toward the front side rather than in the direction in which the first portion 38a extends, it may extend between the lower side and the front side or between the upper side and the front side. The end portion on the back side (-X side) of the second portion 38b is connected to the lower end of the first portion 38a. The second portion 38b has a second operation surface 38e. The second operation surface 38e is a surface facing substantially the upper side among the outer surfaces of the second portion 38b. When the user presses the second operation surface 38e downward, the lever portion 36 rotates downward. Thereby, the head portion 32 can be pushed down by the first lever portion 37, so that the content can be discharged from the discharge port 33a of the nozzle portion 33.
[0032] The connecting portion 36a is a part of the lever portion 36. The connecting portion 36a is a portion between the end portion on the back side (-X side) of the lever portion 36 and the portion in contact with the head portion 32. In the present embodiment, the connecting portion 36a is a portion of the lever portion 36 on the back side of the opening 37a. When viewed from the second direction D2, the connecting portion 36a has a curved shape that protrudes upward. The radius of curvature of the connecting portion 36a increases as it goes toward the front side (+X side).
[0033] FIG. 6 is a side view showing a first usage example of the ejection device 10 of the present embodiment. The ejection device 10 of the present embodiment can be operated with one hand by the consumer in three states: a state where the ejection device 10 is placed on the floor, a state where the consumer holds the ejection device 10, and a state where the ejection device 10 is hooked on a rod-shaped member. As a first usage example of the ejection device 10, the operation in the state where the ejection device 10 is placed on the floor will be described.
[0034] As shown in FIG. 6, when the ejection device 10 is used in a state where it is placed on the floor, the ejection device 10 is placed on the floor surface F. More specifically, the ejection device 10 is placed on the floor surface F when the bottom portion 20a of the container main body 20 comes into contact with the floor surface F in the vertical direction. For example, when the consumer presses the second operation surface 38e of the second portion 38b downward with a finger while turning the palm upward, as described above, the lever portion 36 rotates downward. Thereby, the head portion 32 can be pushed down by the first lever portion 37, so that the content is ejected in a foamy state from the discharge port 33a of the nozzle portion 33 toward the palm of the consumer's hand. Therefore, in the state where the ejection device 10 is placed on the floor, the consumer can operate the ejection device 10 with one hand.
[0035] FIG. 7 is a side view showing a second usage example of the ejection device 10 of the present embodiment. Next, as a second usage example of the ejection device 10, the operation in the state where the consumer holds the ejection device 10 will be described.
[0036] As shown in Fig. 7, when the user uses the ejection device 10 while gripping it, the user grips the ejection device 10, for example, by supporting the support member 34 from the back side (-X side) with the thumb and supporting the second portion 38b from the front side (+X side) with the other fingers. When the user presses the first operation surface 38d of the first portion 38a in a direction facing between the lower side and the back side with the other fingers, as described above, the lever portion 36 rotates downward. As a result, the head portion 32 can be pushed down by the first lever portion 37, so that the content is ejected in a foamy form from the discharge port 33a of the nozzle portion 33 toward the user's fingers. Therefore, in a state where the user grips the ejection device 10, the user can operate the ejection device 10 with one hand.
[0037] Fig. 8 is a first side view showing a third usage example of the ejection device 10 of the present embodiment. Fig. 9 is a second side view showing a third usage example of the ejection device 10 of the present embodiment. Next, as a third usage example of the ejection device 10, an operation in a state where the ejection device 10 is hooked on a hooking member 60 which is a rod-shaped member will be described.
[0038] The hanging member 60 shown in FIG. 8 is, for example, a towel rack provided in a washroom, a bathroom, a kitchen, or the like. The hanging member 60 is not limited to a towel rack and may be other members. The hanging member 60 is fixed to the indoor wall surface W. The user rotates the lever portion 36 upward to provide a gap between the lever portion 36 and the head portion 32, and arranges the hanging member 60 in such a gap. Thereby, the lever portion 36 is supported by the hanging member 60 from below. At this time, an upward reaction force against the gravity of the discharge device 10 applied to the hanging member 60 and the gravity of the content stored in the storage portion 21 is applied to the lever portion 36. That is, a force for rotating the lever portion 36 upward is applied to the lever portion 36. As described above, since the lever portion 36 of the present embodiment has the rotation restricting portion 36c (see FIG. 5) that contacts the support surface 34b of the support member 34 when the lever portion 36 rotates upward by the allowable angle α, even if a force for rotating the lever portion 36 upward is applied, it is possible to suppress the lever portion 36 from rotating upward beyond the allowable angle α. Thereby, it is possible to suppress the lever portion 36 from rotating too much upward, and thus the state in which the first lever portion 37 extends in the first direction D1 is maintained. Therefore, it is possible to suppress the lever portion 36 from coming off the hanging member 60, and thus the discharge device 10 can be hooked on the hanging member 60.
[0039] Also, as described above, the connecting portion 36a, which is the portion between the end portion on the back side (-X side) of the lever portion 36 and the portion in contact with the head portion 32, has a curved shape that protrudes upward, and the radius of curvature of the connecting portion 36a increases as it goes toward the front side (+X side). Therefore, since the radius of curvature of the portion on the back side of the connecting portion 36a can be made small, while extending the portion on the back side of the connecting portion 36a from the upper end of the support member 34 toward the space between the upper side and the front side, the portion on the front side of the connecting portion 36a can be formed into a shape close to a straight line extending in the first direction D1. As a result, while arranging the portion on the front side of the connecting portion 36a above the head portion 32, the direction in which the surface of the portion of the connecting portion 36a that contacts the head portion 32 faces can be made closer to the lower side. Therefore, the direction in which the surface of the portion of the connecting portion 36a that contacts the head portion 32 faces can be made closer to the lower side, which is the direction in which the gravity of the discharge device 10 applied to the lever portion 36 and the gravity of the content accommodated in the accommodation portion 21 act. Therefore, since the lever portion 36 can be prevented from moving on the engaging member 60 toward the front side or the back side, the discharge device 10 can be stably hooked on the engaging member 60.
[0040] As shown in FIG. 9, when the discharge device 10 is used in a state of being hooked on the hooking member 60, the user, for example, presses the second operation surface 38e of the second portion 38b downward with a finger while turning the palm upward. At this time, due to the force applied by the user to the second operation surface 38e, the discharge device 10 tends to rotate about the hooking member 60. When the discharge device 10 rotates about the hooking member 60, among the force applied by the user to the second operation surface 38e, the force that presses down the head portion 32 and is transmitted to the head portion 32 via the hooking member 60 becomes smaller. Therefore, the operability of the discharge device 10 deteriorates. In contrast, in the present embodiment, as described above, the second distance L2, which is the distance between the container axis J1 and the end portion on the back side (-X side) of the container body 20, is equal to or greater than the first distance L1, which is the distance between the container axis J1 and the end portion on the back side of the lever portion 36. In the present embodiment, the second distance L2 is longer than the first distance L1. The second distance L2 may be the same as the first distance. As a result, since it is easy to shorten the distance between the container body 20 and the wall surface W, when the user presses the second operation surface 38e downward, it is easy to reduce the angle at which the discharge device 10 rotates about the hooking member 60. Therefore, it is possible to suppress a decrease in the force transmitted to the head portion 32 via the hooking member 60 among the force applied by the user to the second operation surface 38e. Thus, the user can easily press down the head portion 32 by pressing the second operation surface 38e downward to discharge the content. Therefore, it is possible to suppress a decrease in the operability of the discharge device 10. When the user presses the second operation surface 38e downward, the content is discharged in a foamy form from the discharge port 33a of the nozzle portion 33 toward the palm of the user's hand. Therefore, in a state where the discharge device 10 is hooked on the hooking member 60, the user can operate the discharge device 10 with one hand.
[0041] According to the present embodiment, the lever portion 36 has a curved shape that protrudes upward, including a first lever portion 37 extending from the upper end of the support member 34 toward the front side (+X side), and a second lever portion 38 connected to the front-side end of the first lever portion 37 and disposed on the front side and lower side of the nozzle portion 33. A part of the first lever portion 37 is disposed above the head portion 32 and pushes down the head portion 32 when the lever portion 36 is rotated downward. An opening 37a through which the nozzle portion 33 passes is provided in the first lever portion 37. The second lever portion 38 has a first portion 38a whose upper end is connected to the first lever portion 37 and is located on the front side as it extends downward, and a second portion 38b extending toward the front side relative to the direction in which the first portion 38a extends. Thus, as described above, when the discharge device 10 is placed on the floor, the user can rotate the lever portion 36 downward, for example, by pressing the second operation surface 38e of the second portion 38b downward with a finger while facing the palm upward. Thereby, the content can be discharged from the discharge port 33a of the nozzle portion 33. Therefore, when the discharge device 10 is placed on the floor, the user can operate the discharge device 10 with one hand. Also, as described above, when the user holds the discharge device 10, the user can rotate the lever portion 36 downward, for example, by pressing the first operation surface 38d of the first portion 38a in the direction facing between the lower side and the rear side while supporting the support member 34 from the rear side (-X side) with the thumb. Thereby, the content can be discharged from the discharge port 33a. Therefore, when the user holds the discharge device 10, the user can operate the discharge device 10 with one hand. Therefore, the user can operate the discharge device 10 with one hand in each of the state where the discharge device 10 is placed on the floor and the state where the user holds the discharge device 10. Thus, the convenience of the discharge device 10 can be enhanced.
[0042] Also, in the present embodiment, as described above, the second lever portion 38 is disposed on the front side (+X side) and the lower side of the nozzle portion 33. Therefore, when the user presses the second operation surface 38e downward in a state where the ejection device 10 is placed on the floor, and when the user presses the first operation surface 38d in a direction facing between the lower side and the back side (-X side) while holding the ejection device 10, it is easy to prevent the user's finger or the like from contacting the nozzle portion 33. Therefore, the operation performance of the user operating the ejection device 10 can be improved. Thus, the convenience of the ejection device 10 can be more preferably enhanced.
[0043] Also, in the present embodiment, as described above, the ejection device 10 can be used while the user holds the ejection device 10. Therefore, compared with the case where the ejection device 10 cannot be used while the user holds the ejection device 10 and can only be used in a state where the ejection device 10 is placed on the floor, it is possible to prevent dirt from adhering to the bottom portion 20a of the container body 20. Therefore, it is possible to prevent the hygiene of the bottom portion 20a of the container body 20 from deteriorating.
[0044] According to the present embodiment, the lever portion 36 has a rotation restricting portion 36c that contacts the support member 34 when the lever portion 36 rotates upward by an allowable angle α. Therefore, when the ejection device 10 is used in a state of being hooked on the hooking member 60, as described above, by rotating the lever portion 36 upward, the hooking member 60 can be disposed in the gap between the lever portion 36 and the head portion 32. Thereby, the lever portion 36 can be supported by the hooking member 60. Further, when the lever portion 36 rotates upward by the allowable angle α, the rotation restricting portion 36c contacts the support surface 34b of the support member 34. Therefore, as described above, it is possible to suppress the lever portion 36 from rotating too far upward. Thereby, since the state where the first lever portion 37 extends in the first direction D1 can be maintained, the ejection device 10 can be hooked on the hooking member 60. A user can rotate the lever portion 36 downward by pressing the second operation surface 38e downward with a finger or the like as described above in a state where the ejection device 10 is hooked on the hooking member 60. Thereby, since the user can push down the head portion 32, the content can be ejected from the discharge port 33a of the nozzle portion 33. Therefore, even in a state where the ejection device 10 is hooked on the hooking member 60, the user can operate the ejection device 10 with one hand. Therefore, the convenience of the ejection device 10 can be more suitably enhanced.
[0045] According to the present embodiment, the rotation restricting portion 36c is a surface provided on a portion on the back side (-X side) of the lever portion 36. Therefore, since the rotation restricting portion 36c is a part of the lever portion 36, it is possible to suppress an increase in the number of parts of the ejection device 10 as compared with a configuration in which the upward rotation of the lever portion 36 is suppressed by a member separate from the lever portion 36. Therefore, it is possible to suppress an increase in the manufacturing cost of the ejection device 10.
[0046] According to the present embodiment, the second distance L2, that is, the distance between the container axis J1, which is the central axis of the container body 20, and the end on the back side (-X side) of the container body 20, is equal to or greater than the first distance L1, that is, the distance between the container axis J1 and the end on the back side of the lever portion 36. Therefore, as described above, when the discharge device 10 is used in a state of being hooked on the hooking member 60, it is easy to shorten the distance between the container body 20 and the wall surface W. For this reason, when the user presses the second operation surface 38e downward, it is easy to reduce the angle by which the discharge device 10 rotates about the hooking member 60. As a result, as described above, it is possible to suppress a decrease in the force transmitted to the head portion 32 via the hooking member 60 among the forces applied by the user to the second operation surface 38e, so that the head portion 32 can be easily pushed down. Therefore, when the discharge device 10 is used in a state of being hooked on the hooking member 60, it is possible to suppress a decrease in the operability of the discharge device 10.
[0047] According to the present embodiment, the lever portion 36 has a connecting portion 36a, which is a portion between the end on the back side (-X side) of the lever portion 36 and the portion in contact with the head portion 32. The connecting portion 36a has a curved shape that protrudes upward, and the radius of curvature of the connecting portion 36a increases as it goes toward the front side (+X side). Therefore, as described above, since the radius of curvature of the portion on the back side of the connecting portion 36a can be reduced, the portion on the front side of the connecting portion 36a can be disposed above the head portion 32. As a result, by rotating the lever portion 36 downward, the head portion 32 can be pushed down by the lever portion 36. Further, as described above, since the direction in which the surface of the portion of the connecting portion 36a in contact with the head portion 32 faces can be made closer to the lower side, the discharge device 10 can be stably hooked on the hooking member 60. Therefore, the convenience of the discharge device 10 can be more suitably enhanced.
[0048] The preferred embodiments of the present invention have been described above. Needless to say, the present invention is not limited to such examples. In each of the states of being placed on the floor and being held by the user, as long as the discharge device can be operated with one hand, those skilled in the art can obtain the above effects based on this criterion. In addition, the various shapes, combinations, etc. of the respective constituent members shown in the above examples are merely examples, and can be variously changed based on design requirements and the like without departing from the gist of the present invention.
[0049] The rotation restricting portion does not necessarily have to be a lever portion. For example, when the lever portion rotates by an allowable angle upward, it contacts both the lever portion and the support member to suppress the upward rotation of the lever portion. It may be a member separate from the lever portion.
