Description

  The present invention relates to a discharge container.

  A syringe-shaped discharge container for discharging contents is known. For example, in the discharge container of Patent Document 1, the contents are discharged by pushing a pushing member slidably inserted into the discharge cylinder main body that stores the contents into the discharge cylinder main body.

JP 2002-721 A

  However, since the discharge container as described above has a structure in which the pushing member is manually pushed to discharge the contents, it is difficult to discharge a fixed amount of the contents.

  In view of the above problems, an object of the present invention is to provide a discharge container capable of discharging a fixed amount of content with a simple operation.

  One aspect of the discharge container of the present invention includes a discharge cylinder main body in which a discharge hole for contents is formed at an end on the axial front end side, and an end on the axial front end side in the axial direction within the discharge cylinder main body. A pushing member that is movably fitted toward the distal end side, an urging means that urges the pushing member toward the distal end side in the axial direction, and an axial base end that is more axial than the discharge cylinder main body in the pushing member A first engagement projection piece and a second engagement projection piece separately disposed on both sides sandwiching the outer surface of the outer portion located on the side in one of the radial directions, and On the outer surface of the outer portion, a first engagement portion with which the first engagement protrusion piece engages and a second engagement portion with which the second engagement protrusion piece engages are spaced apart in the axial direction. A plurality of the first engagement projection pieces and the first engagement portion are engaged with each other, and the second engagement projection pieces are pushed in. The first engagement protrusion piece and the second engagement protrusion piece are engaged with each other with the second engagement protrusion piece and the second engagement portion, In addition, the first engaging projecting piece is arranged to be elastically displaceable in the one direction toward a position separated from the pushing member in the one direction.

According to one aspect of the discharge container of the present invention, since the first engagement protrusion and the second engagement protrusion are elastically displaceable, the first engagement protrusion and the second engagement protrusion are arranged. The pushing member can be moved to the front end side in the axial direction by the urging means by elastically displacing the piece and releasing the engagement between the first engaging protrusion and the first engaging portion. Thereby, the contents in the discharge cylinder main body can be pushed out by the pushing member, and the contents can be discharged from the discharge holes. And the movement of a pushing member can be stopped by engaging a 1st engagement protrusion with a 1st engagement part again. Therefore, the first engagement protrusion is pushed by the distance in the axial direction between the first engagement portion with which the first engagement protrusion was first engaged and the first engagement portion with which the first engagement protrusion is next engaged. The member can be moved to the tip end side in the axial direction. As a result, the user can easily move the pushing member by a distance corresponding to the interval at which the first engaging portion is disposed in the axial direction, and discharge the content of the amount corresponding to the moving amount of the pushing member. Can be made. As described above, according to one aspect of the discharge container of the present invention, a discharge container capable of discharging a fixed amount of content with a simple operation is obtained.
In addition, since the first engagement protrusion and the second engagement protrusion can be displaced to a position where the second engagement protrusion is engaged with the second engagement portion, the second engagement protrusion is The movement of the push-in member toward the distal end in the axial direction can also be stopped by engaging with the two engaging portions. Thereby, it becomes possible to adjust the moving amount | distance to the axial direction front end side of a pushing member with high precision, and the operativity of a discharge container can be improved more.

The first engaging portion and the second engaging portion may be arranged at different positions in the axial direction.
For example, depending on the amount of displacement of the first engagement protrusion and the second engagement protrusion, the first engagement protrusion and the second engagement protrusion are equal to each other. When the second engagement protrusion and the second engagement portion are in a position separated in one direction, the movement of the pushing member toward the distal end side in the axial direction is the first engagement portion and the second engagement. It is not regulated by the merger. Therefore, if the user adjusts the amount of displacement of the first engagement protrusion and the second engagement protrusion and does not engage any of the engagement protrusions with any of the engagement portions, the pushing member is In some cases, the content continues to move toward the front end in the direction, and the content continues to be discharged. In this case, it may be difficult to discharge a fixed amount of contents.

  On the other hand, according to this configuration, before the engagement between the first engagement protrusion and the first engagement portion is released, or the engagement between the first engagement protrusion and the first engagement portion. Even when the second engaging protrusion moves to a position where it overlaps the second engaging portion in the axial direction immediately after the is released, the second engaging protrusion and the second engaging portion are immediately engaged. Instead, the pushing member moves toward the axial front end side by the difference in the axial position between the first engaging portion and the second engaging portion. Therefore, the push-in member is axially moved while ensuring that at least one of the first engagement protrusion and the first engagement portion, and the second engagement protrusion and the second engagement portion are always overlapped in the axial direction. It is possible to move to the tip side. As a result, regardless of the amount of displacement of the first engagement protrusion and the second engagement protrusion, it is possible to suppress the pushing member from continuing to move toward the distal end side in the axial direction and to discharge the contents. Accordingly, it is easy to move the pushing member by a distance corresponding to the interval at which the first engaging portions are arranged in the axial direction, and it is possible to discharge a fixed amount of content with a simpler operation.

The first engagement protrusion and the first engagement portion are engaged with each other, and the second engagement protrusion is separated from the push-in member in the one direction. The radial dimension of the portion of the protruding piece that overlaps the first engaging portion in the axial direction may be larger than the radial distance between the second engaging protruding piece and the second engaging portion.
According to this configuration, when the first engagement protrusion and the second engagement protrusion are moved in one direction, the engagement state between the first engagement protrusion and the first engagement portion is released. The second engagement protrusion moves to a position overlapping the second engagement portion in the axial direction. As a result, the first engagement protrusion and the second engagement protrusion are connected to the first engagement protrusion and the first engagement portion regardless of the displacement amount of the first engagement protrusion and the second engagement protrusion. Are not spaced apart in one direction, and the second engaging protrusion and the second engaging portion are not spaced apart in one direction. Therefore, regardless of the amount of displacement of the first engagement protrusion and the second engagement protrusion, the movement of the pushing member toward the distal end in the axial direction is restricted by at least one of the first engagement portion and the second engagement portion. It is possible. As a result, the user can reliably discharge a fixed amount of content corresponding to the interval at which the first engaging portion is disposed in the axial direction.

The surface facing the distal end side in the axial direction of the first engaging portion is a flat surface substantially orthogonal to the axial direction, and the surface facing the proximal end side in the axial direction of the first engaging portion is directed outward in the radial direction. An inclined surface extending toward the distal end side in the axial direction, and a surface facing the proximal end side in the axial direction of the first engagement projecting piece is in contact with a surface facing the distal end side in the axial direction of the first engagement portion and is substantially the axial direction. It is good also as a structure which is an orthogonal flat surface.
According to this configuration, the movement of the push-in member toward the distal end side in the axial direction can be reliably restricted by the engagement between the first engagement protrusion and the first engagement portion. Further, for example, when the pushing member is moved to the axial base end side to return the axial position, the first engaging protrusion is moved by the inclined surface facing the axial base end side of the first engaging portion. It is elastically displaced in the direction in which the engagement with the one engaging portion is released, and does not hinder the axial movement of the pushing member. That is, in the state in which the first engagement protrusion and the first engagement portion are engaged, the first engagement protrusion and the first engagement portion are axial in the axial movement of the pushing member. A ratchet mechanism that allows only movement toward the base end side is configured. Therefore, it is easy to push the pushing member toward the axial base end side and return to the initial position while restricting the movement of the pushing member toward the axial distal end side by each engaging portion.

An outer cylinder that is connected to the axial base end side of the discharge cylinder main body and accommodates the pushing member is further provided. The outer cylinder is formed with a window hole penetrating the outer cylinder in the radial direction, and the pushing member It is good also as a structure by which the operation part which protrudes outside the said outer cylinder through the said window hole is attached to the said outer part.
According to this configuration, the user can easily move the pushing member toward the axial base end side through the portion of the operation portion that protrudes outside the outer cylinder. Therefore, it is easier to return the axial position of the pushing member to the initial position.

It is good also as a structure further provided with the outer cylinder which is connected to the axial direction base end side of the said discharge cylinder main body, and accommodates the said pushing member, and the said discharge cylinder main body is provided detachably with respect to the said outer cylinder.
According to this configuration, after the contents in the discharge cylinder main body are completely discharged, the discharge container can be repeatedly used by replacing the discharge cylinder main body with a discharge cylinder main body filled with the contents.

  According to one aspect of the present invention, a discharge container capable of discharging a fixed amount of content with a simple operation is provided.

As shown in FIGS. 3 and 4, the pushing portion 41 is inserted into the through hole 31 a of the body portion 31 and attached to the fixing portion 42 c of the plate member 42. The pushing portion 41 includes a main body portion 43 and a holding portion 44.
The main body 43 has a side wall 43a and a cylinder 43b. The shape of the side wall 43a viewed from the outside in the radial direction (displacement direction) is a rectangular shape with rounded corners that are long in the axial direction, as shown in FIG. As shown in FIGS. 3 and 4, the side wall 43 a is exposed to the outside of the outer cylinder 30.
The cylinder portion 43b has a rectangular cylinder shape extending radially inward from the outer edge of the side wall portion 43a. The cylinder portion 43 b is inserted through the through hole 31 a of the trunk portion 31. An engaging convex portion 43c is provided on the outer surface of the radially inner end of the cylindrical portion 43b. The engagement convex part 43c is a frame shape provided over the entire circumference of the cylinder part 43b.

The holding portion 44 has a rectangular cylindrical shape that protrudes radially inward from the radially inner side surface of the side wall portion 43a. In the holding part 44, the fixing part 42c of the plate member 42 is fitted and fixed.
Since the base portion 42a is urged away from the spring portion 42b by the spring portion 42b, the pushing portion 41 attached to the fixing portion 42c is urged radially outward (right side in FIGS. 3 and 4). . Thereby, the engagement convex part 43c is contacting the edge part of the through-hole 31a from the radial inside on the internal peripheral surface of the trunk | drum 31, in the state of FIG.

  The discharge mechanism 40 can take two states, the state shown in FIG. 3 and the state shown in FIG. 4, as the spring portion 42 b is elastically deformed in the displacement direction. The state shown in FIG. 3 is a state where no external force is applied to the discharge mechanism 40. The state shown in FIG. 4 is a state in which an external force inward in the radial direction (displacement direction) is applied to the pushing portion 41. In the following description, the state shown in FIG. 3 is called a steady state, and the state shown in FIG. 4 is called a pushed-in state.

  In the steady state shown in FIG. 3, the first engagement protrusion 45 and the first engagement portion 55 are engaged with each other. More specifically, the first base end side surface 45b of the first engagement protrusion 45 is in contact with the first front end side surface 55a of the first engagement portion 55, so that the first engagement protrusion 45 and the first engagement The joint portion 55 is engaged with each other. As described above, a part of the plate member 42 is in contact with the restricting portion 35 of the outer cylinder 30 from the axial base end side, so that the movement of the plate member 42 toward the distal end side in the axial direction is restricted. Thereby, in a steady state, the pushing member 50 urged toward the axial front end side by the urging means 60 is restricted from moving toward the axial front end side.

  In the steady state, the second engagement protrusion 46 is separated from the pushing member 50 in the displacement direction (right side in the drawing). That is, the steady state is a state in which the first engagement protrusion 45 and the first engagement portion 55 are engaged with each other and the second engagement protrusion 46 is separated from the pushing member 50 in the displacement direction. is there. In the steady state, the radial dimension of the portion of the first engagement protrusion 45 that overlaps the first engagement portion 55 in the axial direction is the radial dimension between the second engagement protrusion 46 and the second engagement portion 56. Greater than distance.

  In the pushed state shown in FIG. 4, the second engagement protrusions 46 and the second engagement portions 56 are engaged with each other. More specifically, the second base end side surface 46b of the second engagement protrusion 46 comes into contact with the second front end side surface 56a of the second engagement portion 56, so that the second engagement protrusion 46 and the second engagement The joining portion 56 is engaged with each other. Thereby, in the pushing state, the pushing member 50 biased to the axial front end side by the biasing means 60 is restricted from moving to the axial front end side.

  In the pushed state, the first engaging protrusion 45 is separated from the pushing member 50 in the displacement direction (left side in the figure). That is, the pushed state is a state in which the second engagement protrusion 46 and the second engagement portion 56 are engaged with each other, and the first engagement protrusion 45 is separated from the push member 50 in the displacement direction. is there. In the pushed-in state, the radial dimension of the portion of the second engagement projection 46 that overlaps the second engagement portion 56 in the axial direction is the radial dimension between the first engagement projection 45 and the first engagement portion 55. Greater than distance.

  The discharge mechanism 40 can move in the displacement direction between the steady state and the pushed-in state described above because the spring portion 42b can be elastically deformed. As a result, the first engagement protrusion 45 and the second engagement protrusion 46 are engaged with each other from the steady state position by the second engagement protrusion 46 and the second engagement portion 56. The one engaging protrusion 45 is disposed so as to be elastically displaceable in the displacement direction toward a position away from the pushing member 50 in the displacement direction, that is, a position in the pushed state.

Next, the discharge method of the content W in the discharge container 10 of this embodiment is demonstrated.
First, the user applies a force inward in the radial direction to the pushing portion 41 as shown in FIG. 4 with respect to the discharge mechanism 40 in the steady state shown in FIG. 3 to push the pushing portion 41 inward in the radial direction. Thereby, the spring part 42b is elastically deformed, and the base part 42a and the fixing part 42c of the plate member 42 move in a direction approaching the spring part 42b (leftward in the drawing), and the first engagement protrusion 45 and the first engagement part The engagement with 55 is released. Therefore, the push-in member 50 is urged by the urging means 60 and moves toward the distal end side in the axial direction until the second engagement protrusion 46 is engaged with the second engagement portion 56. In the present embodiment, since the first engagement portion 55 and the second engagement portion 56 are arranged with a half-pitch shift in the axial direction, the pushing member 50 is arranged at the half-pitch of each engagement portion on the distal end side in the axial direction. At the time of movement, the second engagement protrusion 46 is engaged with the second engagement portion 56, and the movement of the pushing member 50 is stopped. Thereby, the discharge mechanism 40 will be in the pushing state shown in FIG.

  Next, the user releases the radially inward force applied to the pushing portion 41. Thereby, the pushing part 41, the base part 42a of the plate member 42, and the fixing part 42c move in a direction away from the spring part 42b (rightward in the drawing) by the urging of the spring part 42b. As a result, the engagement between the second engagement protrusion 46 and the second engagement portion 56 is released. Therefore, the push-in member 50 is urged by the urging means 60 and moves toward the distal end in the axial direction until the first engagement protrusion 45 is engaged with the first engagement portion 55. In the present embodiment, since the first engagement portion 55 and the second engagement portion 56 are arranged with a half-pitch shift in the axial direction, the pushing member 50 is arranged at the half-pitch of each engagement portion on the distal end side in the axial direction. At the time of movement, the first engagement protrusion 45 is engaged with the first engagement portion 55, and the movement of the pushing member 50 is stopped. Thereby, the discharge mechanism 40 will be in the pushing state shown in FIG. At this time, the first engagement portion 55 with which the first engagement protrusion 45 is engaged is the first engagement with which the first engagement protrusion 45 is engaged in the steady state before the pushing portion 41 is pushed. The first engaging portion 55 is disposed adjacent to the proximal end side in the axial direction of the portion 55.

  As described above, when the user performs the operation of pressing the pushing portion 41 and releasing it once, the pushing member 50 has an axial tip corresponding to one pitch in which the first engaging portion 55 and the second engaging portion 56 are arranged. Move to the side. As a result, the closing member 51 moves in the discharge cylinder main body 20 toward the front end in the axial direction by one pitch of each engaging portion, and the contents W are pushed out of the discharge cylinder main body 20 through the discharge holes 24. In this way, the contents W can be discharged.

According to the present embodiment, as described above, since the first engagement protrusions 45 and the second engagement protrusions 46 are arranged to be elastically displaceable, the first engagement protrusions 45 and the second engagements are arranged. The pushing member 50 is moved to the front end side in the axial direction by the urging means 60 by releasing the engagement between the first engaging protruding piece 45 and the first engaging portion 55 by elastically displacing the mating protruding piece 46. Can do. Thereby, the content W can be discharged from the discharge hole 24. And the movement of the pushing member 50 can be stopped by engaging the 1st engaging protrusion 45 with the 1st engaging part 55 again. Therefore, the axial distance between the first engagement portion 55 that the first engagement protrusion 45 is engaged first and the first engagement portion 55 that the first engagement protrusion 45 is engaged next is the same. The pushing member 50 can be moved to the tip end side in the axial direction by the amount. Accordingly, the user can easily move the pushing member 50 by a distance corresponding to the interval at which the first engaging portion 55 is arranged in the axial direction, and the content of the amount corresponding to the moving amount of the pushing member 50. The object W can be discharged. As described above, according to the present embodiment, it is possible to obtain the discharge container 10 capable of discharging a fixed amount of the contents W with a simple operation.
Further, since the first engagement protrusion 45 and the second engagement protrusion 46 can be displaced to a position where the second engagement protrusion 46 engages with the second engagement portion 56, the second engagement The movement of the pushing member 50 toward the distal end in the axial direction can also be stopped by engaging the projecting piece 46 with the second engaging portion 56. Thereby, it becomes possible to adjust the moving amount | distance to the axial direction front end side of the pushing member 50 with high precision, and the operativity of the discharge container 10 can be improved more.

  Further, for example, the first engagement protrusion 45 and the second engagement protrusion 46 are separated from each other in the displacement direction by the pressing amount of the pressing portion 41. When the second engaging protrusion 46 and the second engaging portion 56 are separated from each other in the displacement direction, the movement of the pushing member 50 toward the distal end side in the axial direction is the first engaging portion 55 and the second engaging portion. The joint portion 56 is not restricted. Therefore, if the user adjusts the pushing amount of the pushing portion 41 and does not engage any of the engaging protrusions with any of the engaging portions, the pushing member 50 continues to move toward the tip end in the axial direction. The object W may continue to be discharged. In this case, it may be difficult to discharge the fixed content W.

  On the other hand, according to this embodiment, the 1st engaging part 55 and the 2nd engaging part 56 are arrange | positioned in the position which differs in an axial direction. Therefore, before the engagement between the first engagement protrusion 45 and the first engagement portion 55 is released from the steady state, or the first engagement protrusion 45 and the first engagement portion 55 are engaged. Even when the second engagement protrusion 46 moves to a position overlapping the second engagement portion 56 in the axial direction immediately after being released, the second engagement protrusion 46 and the second engagement portion 56 are The push-in member 50 moves to the axial front end side by the difference in axial position between the first engaging portion 55 and the second engaging portion 56 without being immediately engaged. This is because the engagement between the second engagement protrusion 46 and the second engagement portion 56 is released from the pushed state, or the engagement between the second engagement protrusion 46 and the second engagement portion 56. The same applies to the case where the first engagement protrusion 45 moves to a position overlapping the first engagement portion 55 in the axial direction immediately after the is released. Accordingly, the first engagement protrusion 45 and the first engagement portion 55, and the second engagement protrusion 46 and the second engagement portion 56 are always pushed in while being in an axially overlapping state. It is possible to move the member 50 toward the front end side in the axial direction. As a result, it is possible to suppress the pushing member 50 from continuing to move toward the distal end in the axial direction regardless of the pushing amount of the pushing portion 41 and to discharge the contents W. Thereby, it is easy to move the pushing member 50 by a distance corresponding to the interval at which the first engaging portions 55 are arranged in the axial direction, and it is possible to discharge the quantitative content W with a simpler operation. .

  Particularly in the present embodiment, in the pushed-in state, the radial dimension of the portion of the first engagement protrusion 45 that overlaps the first engagement portion 55 in the axial direction is the second engagement protrusion 46 and the second engagement portion. It is larger than the radial distance from 56. Therefore, when the pushing portion 41 is pushed from the steady state to move the first engaging protruding piece 45 and the second engaging protruding piece 46 in the displacement direction, the first engaging protruding piece 45 and the first engaging portion 55 Before the engagement state is released, the end portion on the inner side in the displacement direction of the second engagement protrusion 46 moves to a position overlapping the second engagement portion 56 in the axial direction. As a result, regardless of the pushing amount of the pushing portion 41, the first engaging protruding piece 45 and the second engaging protruding piece 46 are separated, and the first engaging protruding piece 45 and the first engaging portion 55 are separated in the displacement direction. In addition, the second engagement protrusion 46 and the second engagement portion 56 do not become positions that are separated in the displacement direction. Therefore, regardless of the amount of pushing of the pushing portion 41 by the user, the movement of the pushing member 50 toward the distal end side in the axial direction can be restricted by at least one of the first engaging portion 55 and the second engaging portion 56. It has become. As a result, the user can reliably discharge a fixed amount of the content W according to the interval at which the first engagement portions 55 are arranged in the axial direction.

  In addition, according to the present embodiment, in a state where the first engagement protrusion 45 and the first engagement portion 55 are engaged, the first base end side surface 45b of the first engagement protrusion 45 and the first engagement protrusion 45 that are in contact with each other. Both the first tip side surface 55a of the first engaging portion 55 are flat surfaces. Therefore, the movement of the push-in member 50 toward the distal end side in the axial direction can be reliably restricted by the engagement between the first engagement protrusion 45 and the first engagement portion 55. Moreover, the 1st base end side surface 55b of the 1st engaging part 55 is an inclined surface extended toward an axial direction front end side toward a radial direction outer side. Therefore, for example, when the pushing member 50 is moved to the axial base end side to return the axial position, the first engaging protrusion 45 is spring-loaded by the first base end side surface 55b of the first engaging portion 55. It is pushed and elastically displaced in the direction approaching the portion 42b, and does not hinder the axial movement of the pushing member 50. That is, in a state where the first engagement protrusion 45 and the first engagement portion 55 are engaged, the first engagement protrusion 45 and the first engagement portion 55 are in the axial direction of the pushing member 50. A ratchet mechanism that allows only movement toward the proximal side in the axial direction of movement is configured. Therefore, it is easy to push the pushing member 50 toward the proximal end side in the axial direction and return to the initial position as shown in FIG. 2 while restricting the movement of the pushing member 50 toward the distal end side in the axial direction by each engaging portion. is there.

  Further, according to the present embodiment, since the discharge cylinder main body 20 is detachably provided with respect to the outer cylinder 30, the discharge cylinder main body 20 can be easily replaced. Therefore, after the contents W in the discharge cylinder main body 20 are completely discharged, the discharge container 10 can be repeatedly used by replacing the discharge cylinder main body 20 with the discharge cylinder main body 20 filled with the contents W. Specifically, the user first removes the discharge cylinder main body 20 from the outer cylinder 30. At this time, for example, the closing member 51 remains fitted in the discharge cylinder body 20 and is removed at the same time as the discharge cylinder body 20 is removed. And a user moves the pushing member 50 to the axial direction base end side, and returns the position of the pushing member 50 to an initial position. Here, in the present embodiment, as described above, a ratchet mechanism that allows only the movement of the pushing member 50 in the axial direction to the axial base end side is configured, and thus the axial direction of the pushing member 50 is configured. By directly pushing the end portion on the distal end side, the position of the pushing member 50 can be easily returned to the initial position. In the present embodiment, since the closing member 51 is removed together with the discharge cylinder main body 20, the user moves the pushing member 50 by pushing the end portion of the rod 52 on the axial direction front end side, for example. Then, the user attaches the new discharge cylinder main body 20 filled with the contents W to the mouth portion 32 of the outer cylinder 30. A closing member 51 is fitted to the discharge cylinder main body 20 to be replaced in advance, and the closing member 51 is also attached by attaching the discharge cylinder main body 20. In this way, the user can replace the discharge cylinder main body 20.

In the present embodiment, the following configuration can also be adopted.
In the steady state, the radial dimension of the portion of the first engagement protrusion 45 that overlaps the first engagement portion 55 in the axial direction is the radial dimension between the second engagement protrusion 46 and the second engagement portion 56. It may be less than the distance.
Further, the interval at which the plurality of first engaging portions 55 are arranged in the axial direction and the interval at which the plurality of second engaging portions 56 are arranged in the axial direction may be different from each other.
Moreover, the 1st engaging part 55 and the 2nd engaging part 56 may be arrange | positioned in the same position in the axial direction. In this case, for example, in the steady state, the radial dimension of the portion of the first engagement protrusion 45 that overlaps the first engagement portion 55 in the axial direction is the second engagement protrusion 46 and the second engagement portion 56. Or less in the radial direction. Thereby, by adjusting the pushing amount of the pushing part 41, it can be set as the state which both the 1st engagement protrusion 45 and the 2nd engagement protrusion 46 are not engaged, and the 1st engagement part Even if the axial positions of 55 and the second engaging portion 56 are the same, the pushing member 50 can be moved to the distal end side in the axial direction.

Moreover, the shape of the 1st engaging part 55 and the shape of the 2nd engaging part 56 will not be specifically limited if the 1st engaging protrusion 45 and the 2nd engaging protrusion 46 can each be engaged. For example, the first engaging portion 55 and the second engaging portion 56 may be concave portions that are recessed radially inward from the outer peripheral surface of the first rod portion 53.
Further, the closing member 51 and the rod 52 may be fixed to each other or may be an integral member. Further, the outer diameter of the closing member 51 may be uniform over the entire axial direction.
Further, the discharge cylinder main body 20 may not be detachable from the outer cylinder 30.
Further, the outer cylinder 30 may not be provided.

Is formed. The outer window hole 131b is formed in the axially proximal end portion of the body 131. The outer window hole 131b extends in the axial direction. The shape of the outer window hole 131b viewed along the radial direction is a rectangular shape that is long in the axial direction, as shown in FIG. As shown in FIG. 6, the end on the axial base end side of the outer window hole 131 b is at the same position in the axial direction as the end on the front end side in the axial direction of the outer cylindrical portion 33 b of the bottom 33. The end portion of the outer window hole 131b on the distal end side in the axial direction is substantially in the same position as the end portion on the proximal end side in the axial direction of the urging means 60 in the axial direction. The outer window holes 131b are formed on both sides of the central axis O in one of the radial directions (displacement direction in the present embodiment).

An inner window hole 133f that penetrates the wall of the inner cylinder portion 133c in the radial direction is formed in the inner cylinder portion 133c in the bottom portion 133 of the outer cylinder 130. The inner window hole 133f extends in the axial direction. The inner window hole 133f is open to the front end side in the axial direction. The end portion on the axial base end side of the inner window hole 133f is at the same position in the axial direction as the end portion on the distal end side in the axial direction of the outer cylindrical portion 33b of the bottom portion 33. The inner window hole 133f overlaps the outer window hole 131b in the radial direction (displacement direction). Thereby, as shown in FIG. 7, a part of the second rod portion 57 is exposed to the outside of the outer cylinder 130. The inner window holes 133f are formed on both sides of the central axis O in the displacement direction.
Other configurations of the outer cylinder 130 are the same as the configurations of the outer cylinder 30 of the first embodiment.

In the discharge container 110 of the present embodiment, an operation portion 158 that protrudes to the outside of the outer cylinder 130 via the inner window hole 133f and the outer window hole 131b is attached to the axially proximal end portion of the second rod portion 57. It has been. The portion on the proximal end side in the axial direction of the second rod portion 57 corresponds to the outer portion of the pushing member 50.
The operation part 158 has an arm part 158a fixed to the outer peripheral surface of the second rod part 57, and a grip part 158b connected to the radially outer end of the arm part 158a.

The arm portion 158a extends from the outer peripheral surface of the second rod portion 57 to both sides in the displacement direction (both sides in the left-right direction in the drawing). The arm portion 158a is inserted through the inner window hole 133f and the outer window hole 131b. The radially outer end of the arm portion 158a is substantially at the same position as the outer peripheral surface of the body portion 131 in the radial direction.
The grip portions 158b are provided at both ends of the arm portions 158a extending on both sides in the displacement direction. The grip portion 158 b is disposed outside the outer cylinder 130. As shown in FIG. 7, the circumferential dimension of the grip portion 158b is larger than the circumferential dimension of the outer window hole 131b. The shape of the grip portion 158b viewed along the radial direction is a substantially rectangular shape.
The operation unit 158 moves to the axial front end side as the pushing member 50 moves to the axial front end side.
Other configurations of the discharge container 110 are the same as the configurations of the discharge container 10 of the first embodiment.

  According to this embodiment, since the operation part 158 which protrudes outside the outer cylinder 130 through the outer side window hole 131b is provided, the user can set a part protruding outside the outer cylinder 130 in the operation part 158. Thus, the pushing member 50 can be easily moved to the proximal side in the axial direction. Specifically, for example, the user sandwiches and grips two gripping portions 158b in the operation portion 158 in the displacement direction, and applies a force toward the proximal end side in the axial direction. Thereby, the pushing member 50 can be moved to the axial direction base end side with the operation part 158. FIG. Therefore, for example, when the discharge cylinder main body 20 is completely replaced with the discharge cylinder main body 20 filled with the contents W after the content W in the discharge cylinder main body 20 is completely discharged, the axial position of the pushing member 50 is changed. It is easier to return to the initial position.

Note that the outer window hole 131b and the inner window hole 133f may be arranged with the central axis O sandwiched in directions other than the displacement direction in the radial direction. Further, only one outer window hole 131b and one inner window hole 133f may be provided.
The end of the outer window hole 131b on the distal end side in the axial direction may be positioned closer to the proximal end side in the axial direction than the end portion on the proximal end side in the axial direction of the biasing means 60. According to this configuration, the urging means 60 is not visually recognized from the outside of the outer cylinder 130 through the outer window hole 131b, and it is possible to suppress the appearance from deteriorating.
