Description

  According to the present invention, a discharge operation unit disposed so as to be movable up and down with respect to the container main body is operated to be raised and lowered to project upward from the opening on the top surface and to be exposed to the outside, and downward from the opening. In particular, it is possible to prevent the unintentional pressing force from being applied to the discharge operation unit at the storage position with respect to the discharge container that can be mutually converted into a storage position that is immersed in and hidden inside. Concerning.

Conventionally, the following techniques have been proposed as containers in the field to which the discharge container of the present application belongs.
Patent Document 1 proposes a liquid container that can be converted into a use position in which a discharge operation unit (pump device) is raised and lowered with respect to a container body and a storage position in which the discharge operation unit (pump device) is lowered. That is, a pump device provided so as to be movable up and down with respect to the container main body, an operation cylinder that is disposed so as to cover the periphery of the pump device and is rotatably fitted to the container main body, and the operation cylinder Elevating means for elevating and lowering the pump device by rotating operation, and a use position where the nozzle head of the pump device protrudes upward from the opening of the operation cylinder, and a storage position hidden inside from the opening of the operation cylinder There has been proposed a liquid container which can change the position between the two.

  In Patent Document 2, contrary to the above, a discharge container is proposed in which the discharge operation unit (pump device) is fixedly arranged with respect to the container body, while the cover tube moves up and down with respect to the container body. That is, the pump inserted into the container body from above and the nozzle head at the upper end of the pump are covered with a cover cylinder that can be moved up and down by rotating with respect to the container body, and the nozzle cylinder is opened by moving the cover cylinder downward. A discharge container has been proposed in which a discharge operation is enabled by protruding upward from a portion, and the cover cylinder is moved up so that the nozzle head is immersed and hidden in the cover cylinder. In this case, an outer member that rotates in conjunction with the rotation of the cover cylinder is further provided. When the nozzle head is immersed in the cover cylinder by rotating the cover cylinder, the outer member is also moved along with the rotation of the cover cylinder. As a result of the rotation, it has been proposed that the closed wall of the outer member covers the front of the nozzle hole of the nozzle head.

  Patent Document 3 proposes a discharge container in which, as in Patent Document 2, the discharge operation unit (pump device) is fixedly arranged with respect to the container main body, while the cover cylinder moves up and down with respect to the container main body. That is, the pump inserted into the container body from above and the nozzle head at the upper end of the pump are covered with a cover cylinder fitted to the container body so as to be movable up and down, and the cover cylinder is moved downward so that the nozzle head is opened in the cover cylinder. A discharge container has been proposed in which a discharge operation is enabled by protruding upward from a portion, and the cover cylinder is moved up so that the nozzle head is immersed and hidden in the cover cylinder. In this case, when the cover cylinder is moved upward and the nozzle head is immersed in the cover cylinder, the peripheral edge of the nozzle cover that covers the nozzle head from above is applied to the edge of the opening of the cover cylinder from above. It has been proposed to use a stopper for disabling the operation of pushing down the nozzle head by making contact.

  By the way, in any of the above conventional containers, the top surface of the operation cylinder or the cover cylinder is provided with an opening for the nozzle head of the pump device to appear and retract. In this case, even if the periphery of the nozzle head is converted from the opening to a storage state hidden inside, the head of the nozzle head is exposed to the outside through the opening. For this reason, the contents in the container body may be caused by an erroneous operation or unexpected situation such as the head of the nozzle head being accidentally pushed down with a finger, or a projection or rod-like object hitting and pushing down. Will be discharged into the inside of the operation cylinder. Even if the front of the nozzle hole of the nozzle head is covered with the closing wall of the outer shell member as in Patent Document 2, it cannot be sealed, and the discharge pressure of the pump accompanying the depression of the nozzle head As a result, it is considered that a situation in which the contents are discharged occurs. On the other hand, in the case of the above-mentioned Patent Document 3, since the nozzle cover placed over the nozzle head stops the external force in the push-down direction, it is considered that the discharge of the contents can be prevented even if the above-described erroneous operation occurs. It is done. However, in this case, the cover cylinder can be moved up and down with the pump device fixed to the container body, and the movable range in the vertical direction of the cover cylinder is limited to a lower range than the lower surface position of the peripheral edge of the nozzle cover. It is necessary to adopt a structure that does this, and it is subject to design and size constraints.

  In addition, the possibility of occurrence of such troubles is not so high when the container is used in a bathroom, washroom or vanity, etc. In the case of a discharge container configured to be relatively compact as a product, it is considered that the discharge container is considerably high and the influence due to the occurrence of the defect is also considerably increased. For example, while being carried or carried in a bag or bag, the tip of another lipstick or other rod-like material stored in the bag hits the head of the nozzle head in the opening and pushes it. When the pressure acts, the above-mentioned problems are likely to occur. In addition, the discharged contents may cause contamination in the bag.

  The present invention has been made in view of such circumstances, and the purpose of the present invention is to ensure that even if an erroneous operation occurs on the discharge operation unit converted into the storage state or a certain rod-like object hits it. It is an object of the present invention to provide a discharge container that can prevent a push-down force that causes the discharge from being applied to the discharge operation unit.

  In order to achieve the above object, according to the present invention, a container body, a pump device having a discharge operation part at the head and supported so as to be movable up and down with respect to the container body, and the container body covering the periphery of the pump device An operation cylinder member that is rotatably supported about the central axis thereof, and a rotational operation force applied to the operation cylinder member is converted into a lifting operation force of the pump device so that the discharge operation portion is placed on the top surface of the operation cylinder member The following specific matters were provided for a discharge container provided with an elevating means for making it appear and disappear from the opening. That is, it has a closing member, and is provided with an opening / closing means for switching the opening by opening and closing by the closing member. Then, as the opening / closing means, the closing member is operated to close so that the opening is substantially closed in conjunction with the rotation operation of the operation cylinder member for immersing the discharge operation part into the opening. The closing member is retracted so as to open the opening in conjunction with the rotation operation of the operation cylinder member for causing the discharge operation part in the state to protrude from the opening (Claim 1).

  In the case of the present invention, when the operation cylinder member is rotated and the discharge operation portion is immersed in the opening, the opening is substantially closed by the closing member in conjunction with the rotation operation. Even if a push-down force due to an erroneous operation is applied to the discharge operation part in the opening, or any stick-like object hits, the acting external force is stopped by the closing member, or the stick-like object is prevented from entering the opening part. It becomes possible to do. For this reason, it becomes possible to prevent a push-down force that causes unexpected discharge from acting on the discharge operation unit, and to avoid the occurrence of inconveniences such as surrounding contamination due to the occurrence of unexpected discharge. It becomes possible. In addition, since the operation cylinder member can be rotated with respect to the container body and such an action can be realized in the discharge container configured to move the pump device up and down by the rotation operation of the operation cylinder member, the discharge container is configured compactly. In addition, the container main body and the operating cylinder member can be designed integrally, and the appearance can be improved.

  In the discharge container of the present invention, the closing member is a gate member rotatably supported in the vicinity of the periphery of the opening, and the gate member is rotated by rotating the gate member and the operation cylinder member as opening / closing means. And an actuating portion that engages with the gate member, and the actuating portion and the gate member are arranged so that the gate member crosses the opening and closes the opening substantially. The gate member can be configured to rotate to a position and an open position where the gate member retracts from the opening and opens the opening (claim 2). By doing in this way, the substantially closing operation of the opening by the closing member of claim 1 is embodied as the rotation operation of the gate member, and the operational effect of the present invention can be further embodied. That is, when the operation cylinder member is rotated, the operating portion engages with the gate member to rotate the gate member, whereby the gate member is disposed so as to cross the opening and the opening is substantially closed. Become. With this gate member, it is possible to reliably prevent the above-described external force and prevent the rod-like object from entering the opening.

  In the discharge container of the present invention, the operating cylinder member includes an operating portion that extends in parallel with the central axis from a position near the periphery of the opening and is rotated in conjunction with the rotation operation of the operating cylinder member. As a gate member, a gate main body rotatably supported around an axis parallel to the central axis directly or indirectly with respect to the container main body at one end position, and an actuated portion protruding from one end position of the gate main body As the opening / closing means, the operating portion engages with the operated portion as the operating cylinder member rotates in the predetermined rotation direction, and the gate body is closed from the open position. While the conversion operation is performed by rotating to the position, the operation portion is engaged with the gate body in accordance with the rotation operation of the operation cylinder member in the reverse rotation direction, and the gate member can be rotationally converted from the closed position to the open position. (Claim 3 . By doing in this way, the structure for an operation part to rotate an operation of a gate member with rotation operation of an operation cylinder member can be materialized. That is, if the operation cylinder member is rotated, the operating portion is interlocked with the operated portion of the gate member, and the gate member can be rotated.

  Further, in the discharge container of the present invention, when the gate member is rotated by the operating portion and converted to the closed position, a stopper is provided for restricting the rotation range so as to stop the further rotation operation of the operation cylinder member. (Claim 4). By doing so, when the gate member is converted to the closed position by the rotation operation of the operation cylinder member, the rotation operation of the operation cylinder member more than necessary is stopped by the stopper, so the conversion is facilitated with the conversion operation. It is possible to ensure the certainty of operation.

  As described above, according to the discharge container of the present invention, when the operation cylinder member is rotated and the discharge operation portion is immersed in the opening, the opening is substantially closed by the closing member in conjunction with the rotation operation. Therefore, even if a push-down force due to an erroneous operation is applied to the discharge operation part in the opening from the outside of the opening, or a certain rod-like object hits, the acting external force is stopped by the closing member, It is possible to prevent an object from entering the opening. For this reason, it is possible to prevent the push-down force that causes unexpected discharge from acting on the discharge operation unit, and it is possible to avoid the occurrence of inconveniences such as surrounding contamination due to the occurrence of unexpected discharge. . In addition, such an effect can be realized in a discharge container having a configuration in which the operation cylinder member can be rotated with respect to the container main body, and the pump device is moved up and down by the rotation operation of the operation cylinder member. In addition to being able to be compact, the container body and the operation cylinder member can be designed integrally, and the appearance can be improved.

  According to the discharge container of the second aspect, the substantially closing operation of the opening by the closing member of the present invention can be embodied as the rotation operation of the gate member, and the effect of the present invention can be obtained more specifically. become. That is, when the operation cylinder member is rotated, the operating portion engages with the gate member to rotate the gate member, whereby the gate member is disposed so as to cross the opening and the opening is substantially closed. Therefore, the gate member can surely realize that the external force is prevented or the rod-like object is prevented from entering the opening.

  According to the discharge container of claim 3, the configuration for the operating portion to rotate the gate member can be specifically specified in accordance with the rotation operation of the operation cylinder member, and the operation cylinder member can be rotated. In this case, the operating part interlocks with the operated part of the gate member, and the gate member can be rotated.

  Furthermore, according to the discharge container of claim 4, when the gate member is rotated by the operating portion and converted to the closed position, the stopper for restricting the rotation range so as to stop the further rotation operation of the operation cylinder member. When the gate member is converted to the closed position by the rotation operation of the operation cylinder member, the rotation operation of the operation cylinder member more than necessary can be stopped by the stopper, and the conversion operation is easy. At the same time, the certainty of the conversion operation can be ensured.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing three types of state changes of a discharge container according to an embodiment of the present invention, that is, a use state P, a storage state L, and a storage closed state S. In the use state P, a discharge operation portion with discharge holes (hereinafter referred to as “nozzle head”) 41 constituting a part of the pump device 4 to be described later is exposed by protruding upward from the opening 61 on the top surface of the operation cylinder member 6. When the nozzle head 41 is pushed down from above, the contents in the container body 2 can be discharged from the discharge hole 42. In the housed state L, the pump device 4 including the nozzle head 41 is lowered by rotating the operation cylinder member 6 in one direction around the central axis X (rotation operation indicated by T1 in FIG. 1). Is immersed in and stored in the opening 61. In the storage closed state S, when the operation cylinder member 6 is rotated by a predetermined amount in the same direction from the storage state L (rotation operation indicated by reference numeral T2 in the figure), the operating portion 62 is engaged with the gate member 7. As a result of the operation, the gate member 7 is disposed across substantially the center position of the opening 61, and the opening 61 is blocked (see FIG. 2). If the storage closed state S is entered, even if the user's finger or the tip of some rod-like object tries to enter the opening 61 from above, it will hit the gate member 7 and prevent further intrusion (downward). It will be. In order to reversely convert from the storage closed state S to the storage state L, and from the storage state L to the use state P, the operation cylinder member 6 is rotated in the opposite direction in the opposite direction to the rotation operation H2 and T1 in the same amount as T2. The rotation operation may be performed by the same amount of rotation operation H1. Here, the contents refer to liquids, liquids such as gels, creams, and the like. Discharge means that the contents are ejected or sprayed in addition to being slowly discharged or ejected by a push-down operation of the nozzle head. This also includes the concept of

  In the case of this embodiment, such a discharge container includes a container main body 2 filled with contents, a tubular member 3 screwed into the mouth portion 21 of the container main body 2, A pump device 4 having a nozzle head 41 at the head, a slider member 5 that holds the pump device 4 inside, and an operation cylinder member 6 that is rotatably provided to the container body 2 via the cylindrical member 3; And a gate member 7 which is a closing member pivotally supported by the cylindrical member 3. In order to assemble these into a discharge container, as shown in FIG. 4, first, the annular coupling portion 31 at the lower end portion of the cylindrical member 3 is externally fitted and screwed into the mouth portion 21 of the container body 2 from above. Fix (see also FIG. 5). Next, the pump device 4 previously connected to the slider member 5 is inserted into the cylindrical member 3 and the container main body 2 to be in a temporarily assembled state.

  The coupling of the pump device 4 to the slider member 5 and the insertion of the pump device 4 into the slider member 5 are performed as follows. That is, the slider member 5 is provided with arcuate cylindrical wall portions 33, 33 extending upward from the upper surface of the annular coupling portion 31 and facing each other on both sides in the circumferential direction via the guide slits 32, 32, respectively. . On the other hand, the pump device 4 includes a nozzle head 41, a pump body 43 to which a suction tube 431 extending to the inner bottom of the container body 2 is connected, and an attachment 44 integrally coupled around the pump body 43, When the nozzle head 41 is pushed down in the direction of arrow M1 in FIG. 5, for example, the piston in the pump body 43 is pushed down and the contents in the container body 2 sucked through the suction tube 431 are discharged from the discharge holes 42 of the nozzle head 41. It is designed to be discharged. The slider member 5 includes a protective cylinder 51 that extends downward by a predetermined dimension and accommodates the pump main body 43 therein, and an arc-shaped guide piece that extends upward from the opposed outer peripheral positions on the upper side of the protective cylinder 51. 52, 52 and convex shafts 53, 53 for raising and lowering operations that project radially outward from the outer peripheral surfaces of these guide pieces 52, 52. First, the pump main body 43 of the pump device 4 is inserted into the protective cylinder portion 51 from above, and the inner peripheral surface of the attachment 44 is screwed to the upper end portion of the protective cylinder portion 51, whereby the pump device 4 is moved to the slider member. 5, the upper surface opening of the protective cylinder 51 is closed. Next, the guide piece portions 52, 52 on both sides are fitted inside the protective cylinder portion 51 of the slider member 5 in a state where the pump device 4 is coupled, from the upper surface opening 311 of the annular coupling portion 31 of the tubular member 3. Is inserted into the guide slits 32, 32 of the tubular member 3 to temporarily assemble the suction tube 431 into the container body 2 filled with the contents. In this temporarily assembled state, the outer peripheral surface of the protective cylinder portion 51 and the inner peripheral surface of the annular coupling portion 31 are in close contact with each other, thereby allowing the vertical movement of the protective cylinder portion 51 by vertical sliding. However, the inside of the container body 2 is maintained in a substantially sealed state.

  Then, after the gate member 7 is pivotally supported about an axis parallel to the central axis X with respect to the support shaft 34 provided on the upper end surface of the cylindrical wall portion 33 on one side of the cylindrical member 3, FIG. As shown in FIG. 4, the operation cylinder member 6 is attached so as to cover the outer periphery of the cylindrical member 3. This assembly is performed as follows. That is, on the inner peripheral surface of the operation cylinder member 6, as shown in FIG. 7 and FIG. 8A, thick portions 63, 63 are formed in a region that bisects the circumferential direction with the thin portions 64, 64 interposed therebetween. In each thick part 63, a spiral elevating guide groove 65 is formed. An assembly groove 651 extending downward is continuously formed at the lower end side of each elevating guide groove 65. When the operation cylinder member 3 is assembled, the pair of convex shafts 53, 53 of the slider member 5 are formed. It covers so that it may correspond to both the assembly grooves 651 of the inner peripheral surface of the operation cylinder member 3, and each convex shaft 53 can be put in the lower end of the raising / lowering guide groove 65 from the assembly groove 651. If the convex shaft 53 on the lower end side of the lifting guide groove 65 is inserted, the locking portion 66 formed to protrude radially inward at the inner peripheral edge position of the lower end of the operation cylinder member 3 is formed in the cylindrical member 3 (see FIG. 5). The lower end outer peripheral edge of the annular coupling portion 31 is locked. As a result, the operation cylinder member 6 is rotatably coupled around the central axis X of the container body 2 while maintaining a fixed position in the vertical direction in the relative positional relationship with the container body 2. Further, the gate member 7 is retracted between the upper end surface of the cylindrical wall portion 33 on the one side of the cylindrical member 3 and the lower surface of the inner peripheral edge of the opening portion 61 of the operation cylindrical member 6, thereby opening the opening portion 61. It will be arranged at a position (open position) for maintaining the open state. In the illustrated example, the operation cylinder member 6 is indirectly coupled to the container main body 2 via the cylindrical member 3. The operation cylinder member 6 may be directly locked and coupled to the container body 2 in advance.

  In addition, at the inner peripheral side position corresponding to the thin wall portions 64, 64 of the operation cylinder member 6, an operating portion 62 is formed so as to protrude downward from the inner peripheral edge portion forming the opening 61 on one side. A stopper piece 67 (see FIG. 8A) is formed to protrude radially inward. Here, as the operation part 62, what has a semi-cylindrical cross-sectional shape is shown in the example of the drawing, but not limited thereto, other than a columnar shape (for example, refer to the operation part 62 'in FIG. 11) and the like. You may form so that it may have the cross-sectional shape. On the other hand, on the upper end surface of one cylindrical wall portion 33 corresponding to the other side of the cylindrical member 3, convex portions 331 and 331 are formed so as to protrude upward from predetermined positions on both end sides thereof. When the stopper piece 67 comes into contact with the convex portions 331 and 331 in accordance with the rotation operation, the possible range of the rotation operation of the operation cylinder member 6 is restricted.

  On the other hand, as shown in FIG. 9, the gate member 7 has a strip-shaped gate body 71 that is supported by a support shaft 34 at one end side and has a curved shape, and is opposite to the gate body 71 across the support shaft 34. And an actuated portion 72 protruding to the side. Then, the operating portion 62 moves along the inner peripheral surface of the gate body 71 in accordance with the rotation operation of the operation cylinder member 6 around the central axis X (rotation operation indicated by reference characters T1 and H1 in FIG. 1). While the gate member 7 is held in the open position between the use state P to the storage state L in FIG. 1, the operation cylinder member 6 is further slightly rotated (rotation operation indicated by reference numerals T2 and H2 in FIG. 1). Then, when the operating portion 62 is engaged with the operated portion 72 and pushed, the gate member 7 in the open position shown by the one-dot chain line in FIG. 10 is rotated around the support shaft 34 to the closed position shown by the solid line. become. In the closed position, the gate member 7 crosses substantially the center position of the opening 61, and the other end 711 of the gate body 71 rests on the upper end surface of the opposite cylindrical wall 33, and the gate member 7 is supported at both ends. Will be. In order to further increase the smoothness and certainty in position conversion by such rotation operation, for example, a tip taper portion that is obliquely chamfered on the lower surface corner portion of the other end 711 of the gate main body 71 or the gate is formed. It is possible to obliquely chamfer the lower surface corner along the outer peripheral edge 712 (see FIG. 10) of the main body 71 to form an outer peripheral tapered portion. By forming the tip tapered portion, the other end portion 711 of the gate main body 71 can be smoothly and reliably placed on the upper end surface of the cylindrical wall portion 33 from the open position to the closed position, and malfunction due to unnecessary interference. Can be avoided. Further, by forming the outer peripheral side taper portion, when returning from the closed position to the open position, unnecessary interference with the inner peripheral edge of the upper end surface of the cylindrical wall portion 33 is avoided and the gate member 7 is smoothly moved to the open position of FIG. And it becomes possible to return reliably.

  As the gate main body 71 of the gate member 7, in the example shown in the figure, an arc-shaped strip plate having substantially the same width as the cylindrical wall portion 33 of the cylindrical member 3 is shown, but the present invention is not limited to this, and the opening 61 The shape may be adopted as long as it does not interfere with the operation of moving the nozzle head 41 through, for example, a circular arc shape that is looser than that of the cylindrical wall portion 33 or a linear shape. Can do. In addition, as the actuated portion 72 of the gate member 7, the gate member 7 is subjected to a pressing force accompanying the circumferential movement around the central axis X of the actuating portion 62 having a semicircular cross-sectional shape in the illustrated example. Although a predetermined shape is set to smoothly rotate the support shaft 34 by a predetermined angle, the shape is not limited to this, and a simple lever shape may be used. For example, as shown in FIG. 11 in which the gate member 7 ′ has a fundamental shape, the lever-like actuated portion 72 ′ can be projected at a predetermined angle from the shaft fulcrum of the gate body 71 ′ by the support shaft 34. . Note that the crossing angle between the gate main body 71 'and the actuated portion 72' across the shaft fulcrum is, for example, from the open position (see the gate member 7 'shown by a two-dot chain line in FIG. 11) to the closed position (solid line in the figure). Can be set to correspond to the rotation angle to be converted up to the gate member 7 '). In the above, the gate members 7 and 7 'having the operated parts 72 and 72' and the operating parts 62 and 62 'constitute an opening / closing means for switching the opening 61.

  In the discharge container assembled as described above, in the usage state P, for example, the convex shafts 53 of the slider member 5 are the upper ends of the lifting guide grooves 65 and 65 on the inner peripheral surface of the operation cylinder member 6 (reference numerals in FIG. 7). 652), the nozzle head 41 protrudes from the opening 61 (see the use state P in FIG. 1). Then, when the operation cylinder member 6 is rotated in the clockwise direction T1 from this state, the convex shafts 53 and 53 are actuated downward along the elevating guide grooves 65 and 65, and the slider member 5 is lowered together with the pump device 4. At this time, since the guide pieces 52 and 52 are guided by the guide slits 32 and 32 and move downward, the slider member 5 and the pump device 4 are lowered directly without rotating together with the operation cylinder member 6, and the nozzle The head 41 reaches the storage state L stored in the opening 61. In the process of conversion from the use state P to the storage state L, the actuating part 62 moves along the inner periphery of the gate body 71 of the gate member 7 with the rotation operation of the operation cylinder member 6 (rotation operation indicated by T1 in FIG. Since it moves along the side position, the gate member 7 is held in the open position. Then, when the operation cylinder member 6 is further rotated from the stored state L as indicated by reference numeral T2 'in FIG. 9, the operating portion 62 comes into contact with the operated portion 72 and is further rotated slightly in the same direction (reference number in FIG. 10). When the actuating part 62 pushes the actuated part 72 and the gate member 7 is rotated around the support shaft 34 to reach the closed position, the discharge container enters the storage closed state S (see FIG. 1). When the storage closed state S is reached, the stopper piece 67 also moves in the circumferential direction in synchronism with the movement in the circumferential direction of the operating portion 62 and comes into contact with the convex portion 331 of the cylindrical wall portion 33 or is positioned nearest. Further rotation operation of the operation cylinder member 6 becomes impossible (see FIG. 10) The above-described stopper piece 67 and the convex portion 331 are used to restrict the rotation range so that the rotation operation of the operation cylinder member 6 is stopped. Stopper configuration And are. Here is, plus T2 "to the rotating operation T2 'becomes the required rotational operation T2 (see FIG. 1) to convert a stored state L to the accommodated closed state S. A rotation operation angle corresponding to the rotation operation T2 ′ may be added to the rotation operation T1 necessary for conversion from the use state P to the storage state L. In the above, the lifting guide grooves 65, 65 and the convex shafts 53, 53 convert the rotational operation force on the operation cylinder member 6 into the raising / lowering operation force of the pump device 4 so that the nozzle head 41 is opened in the opening 61 of the operation cylinder member 6. Lifting means for making it appear and disappear from is configured.

  In the case of the above embodiment, if the storage cylinder S 6 is turned into the storage closed state S, the opening 61 is closed and shut off by the gate member 7, so that, for example, the discharge containers are stored in the bag in a mixed state. Even if a stick-like object such as a lipstick comes to abut against the inner nozzle head 41 side from the opening 61, the stick-like object hits the gate member 7 and is prevented from entering the opening 61. . Thereby, it is possible to reliably prevent a pressing force that causes unexpected discharge from being applied to the nozzle head 41, and to avoid occurrence of inconvenience such as contamination in the bag due to unexpected discharge. Moreover, the closing conversion of the opening 61 by the gate member 7, that is, the conversion operation from the discharge container to the storage closed state S is performed for the conversion operation from the use state P to the storage state L without any special operation. The operation cylinder member 6 can be automatically performed by a series of rotation operations that are continuous with the rotation operation of the operation cylinder member 6, and a user-friendly discharge container can be realized. At the time of the conversion operation to the storage closed state S, the stopper piece 67 and the convex portion 331 stop the rotation operation of the operation cylinder member 6 more than necessary, so that the conversion operation is facilitated together with the ease of the conversion operation. Certainty can also be ensured. Further, the operation cylinder member 6 can be rotated at a fixed position in the vertical direction, and the nozzle head 41 of the pump device 4 is projected and retracted from the opening of the operation cylinder member 6, so that the discharge container is configured compactly. In addition, the container body 2 and the operation cylinder member 65 can be designed integrally, and the appearance can be improved.

<Other embodiments>
In addition, this invention is not limited to the said embodiment, Various other embodiments are included. That is, in the above-described embodiment, the operation cylinder member 6 or the like is configured with a concentric shape centered on the central axis X, but may be configured with an elliptical shape or an oval shape, for example. In that case, the gate member can be constituted by a linear member, or a plurality of gate members can be provided. Further, although the gate member 7 is composed of a strip-shaped member, it can be composed of a rod-shaped member, a tubular member, or the like.
