  On the outer peripheral surface of the cap 60, a longitudinal knurl 65 is provided over the entire circumference as shown in FIG. By providing the vertical knurls 65 extending in the vertical direction on the outer peripheral surface of the cap 60 in this manner, when the user turns the cap 60 in the circumferential direction to disengage the screw engagement between the cap 60 and the fixed platen 30, the user can use the hand. Work can be performed without slipping. In addition, since the user usually understands the longitudinal knurls 65 as a means for preventing slippage in the rotating direction, it is easy to determine that the discharge container 1 can be disassembled by turning the cap 60 due to the presence of the longitudinal knurls 65. I can understand.

  The cover 40 is formed of, for example, a synthetic resin, is attached to the fixed platen 30 together with the cap 60 from above, and is removable upward. The cover 40 includes a cylindrical tubular wall portion 41 surrounding the mouth portion 11 and an surrounding wall portion 42 extending above the tubular wall portion 41 and surrounding the nozzle 20 in the circumferential direction of the mouth portion 11.

  As shown in FIG. 3, on the inner peripheral surface of the cylindrical wall portion 41 of the cover 40, vertically extending ribs 41b are provided at two locations facing each other on the circumference. The rib 41b is provided for positioning the cover 40 and the fixed board 30 in the circumferential direction. As described above, the ribs 41b are fitted into the openings 37 provided at two locations on the circumference of the top wall 38 of the fixed board 30, whereby the cover 40 and the fixed board 30 are aligned in the circumferential direction. . In the present embodiment, as shown in FIG. 3, two ribs 41b are provided to face each other in the front-rear direction along the central axis of the discharge cylinder 23 of the nozzle 20. By fitting the ribs 41b into the two openings 37 shown in FIG. 4, the push-down lever 50, the nozzle 20 and the like housed in the cover 40 are correctly oriented with respect to the stem 13 of the container body 10. You. In addition, in the container main body 10 of the present embodiment, since the two stems 13 have a symmetrical shape, the cover 40, the push-down lever 50 held by the cover 40, and the nozzle 20 include the fixed platen 30 and the two What is necessary is just to be able to be attached to the stem 13 at any of the two rotation positions rotated by 180 ° around the central axis O of the mouth portion 11. Therefore, the present invention is not limited to the above-described embodiment. For example, the rib 41b may be provided at only one location, and the rib 41b may be configured to fit into one of the openings 37 provided at two locations. . In addition, the rib 41b and the opening 37 may be provided only at one place, and the cover 40 and the like may be attached to the fixed board 30 only at one rotation position around the central axis O. After all, when two stems are provided in the container body 10, the cover 40 and the like can be attached to the fixed platen 30 at two rotation positions rotated by 180 ° around the central axis O, or Either the cover 40 or the like can be attached to the fixed platen 30 only at one rotation position. Therefore, the rib 41b and the opening 37 need only be arranged so that any of the above-mentioned attachments can be performed. When the stems 13 are arranged at three locations on the circumference at every 120 °, the ribs 41b are attached to the openings 37 provided at three locations at every 120 ° at any of the three rotational positions. And so on.

  At the lower end of the cylindrical wall portion 41 of the cover 40, a protruding portion 43 protruding in the outer peripheral direction is provided. As shown in FIGS. 2 and 3, the upper surface of the protrusion 43 of the cover 40 contacts the lower surface of the top wall 63 of the cap 60. Therefore, the downward displacement of the cap 60 is restricted by the protrusion 43. An engagement protrusion 41a is provided on the outer peripheral surface of the cylindrical wall portion 41 above the top wall 63. The engagement projection 41a is reduced in diameter upward so that when the cylindrical wall portion 41 is inserted into the opening 63a of the top wall 63 from below, it is undercut engaged with the upper surface of the top wall 63 and does not easily come off. It is configured to be. Note that the inner diameter of the opening 63 a provided in the top wall 63 is slightly larger than the outer diameter of the cylindrical wall portion 41, so that the cap 60 is attached to the cover 40 by the protrusion 43 and the engagement protrusion 41 a. While the relative displacement in the vertical direction is restricted, the cover 40 is rotatable around the central axis O with respect to the cover 40.

  The surrounding wall portion 42 of the cover 40 defines a housing recess 42 a that surrounds the base portion 21 of the nozzle 20 in the circumferential direction of the mouth portion 11 and protrudes the discharge port 22 outward.

  A push-down lever 50 made of, for example, a synthetic resin is attached to the accommodation recess 42 a above the nozzle 20. The push-down lever 50 has a lever support portion 51 fixed by being fitted to the surrounding wall portion 42 via an undercut shape, and a push-down operating portion having a front end connected to the lever support portion 51 via a hinge 52. 53. The push-down operation section 53 has an abutment projection 53a on its lower surface, and presses down the push-down operation section 53 to push the upper surface of the base 21 of the nozzle 20 downward through the abutment projection 53a. , So that the stem 13 can be pushed down to discharge the contents.

  The discharge container 1 configured as described above can be used by the following operation. First, when the user pushes down the push-down operation section 53 of the push-down lever 50 protruding rearward, the contact protrusion 53 a provided on the lower surface of the push-down lever 50 moves to the upper surface of the base 21 of the nozzle 20. Press. By this operation, the nozzle 20 is also displaced downward, and further presses the stem 13. Thereby, the contents flowing into the nozzle 20 from the stem 13 through the inflow hole 25b can be discharged from the discharge port 22 via the internal space of the base 21 and the discharge cylinder 23.

  Further, in the discharge container 1 configured as described above, the cover 40 can be removed in the following manner for cleaning the nozzle 20 and the cover 40. First, since the discharge container 1 has a substantially cylindrical shape, it is understood that the user can remove the cover 40 by rotating the member. In particular, in this embodiment, since the longitudinal knurls 65 are provided on the outer peripheral surface of the cap 60, the user can easily understand that the cover 40 can be removed by rotating the cap 60 in the circumferential direction. Can be. The user rotates the cap 60 around the central axis O to release the screw engagement between the cap 60 and the fixed platen 30. Since the cap 60 is displaced upward with respect to the fixed platen 30 in the process of disengaging the screw, the cover 40, which is restricted from being displaced in the vertical direction between the projection 43 and the engagement projection 41 a, also has the cap 60. And displaces upward. While the cover 40 is displaced upward, the bottom 45 of the cover 40 (see FIG. 3) comes into contact with the bottom 25 of the nozzle 20. When the cover 40 is further lifted upward, the bottom 45 of the cover 40 raises the bottom 25 of the nozzle 20 upward, and the recess 25 a of the nozzle 20 is pulled out of the stem 13. When the cover 40 is further lifted up when the screw engagement between the cap 60 and the fixed board 30 is completely released, the cover 40 can be removed from the fixed board 30 together with the nozzle 20 and the pressing lever 50.

  In the present embodiment, when removing the cover 40, the nozzle 20 can be removed together with the cover 40 while holding the nozzle 20 in the housing recess 42 a of the surrounding wall portion 42 of the cover 40. Further, the cover 40 and the nozzle 20 held by the cover 40 are attached to the fixed platen 30 and the two stems 13 at any of two rotational positions rotated by 180 ° around the central axis O of the mouth 11. be able to.

  After cleaning the nozzle 20 and the cover 40, the user can return the cover 40 to the state of use shown in FIGS. 2 and 3 in the following manner. First, in the state of FIG. 6 in which the cover 40 is completely removed from the fixed board 30, the user can use the two holes 41 b provided on the cover 40 to form the opening 37 provided on the top wall 38 of the fixed board 30. The cover 40 is positioned in the circumferential direction so that the cover 40 can be inserted into the inside. When the rib 41b and the opening 37 are not aligned in the circumferential direction, the lower end of the rib 41b and the upper surface of the top wall 38 come into contact with each other as shown in FIG. Cannot be moved. In this state, since the lowermost surface of the nozzle 20 is located above the upper end of the stem 13 as shown in FIG. 6, even if the cover 40 is rotated for alignment, the nozzle 20 may come into contact with the stem 13. There is no. As described above, in the present embodiment, the rib 41b can be aligned with the opening 37 at two rotation positions rotated by 180 ° around the central axis O of the mouth portion 11.

  After the circumferential alignment between the rib 41b and the opening 37 is performed in the state of FIG. 6, the user moves the cover 40 downward. At this time, the cap 60 whose relative displacement in the vertical direction with respect to the cover 40 is restricted, the nozzle 20 abutting on the bottom 45 of the cover 40, and the push-down lever 50 fixed to the cover 40 by undercut engagement are also included. , Move downward together with the cover 40. The cover 40 that has been aligned in the circumferential direction moves to a position where the lowermost surface of the female screw portion 61a of the cap 60 contacts the uppermost surface of the male screw portion 31a of the fixed platen 30, as shown in FIG.

  In the state shown in FIG. 7, the user grips and rotates the longitudinal knurl 65 of the cap 60 to screw-engage the cap 60 and the fixed platen 30. At this time, the cover 40 has the rib 41b fitted into the opening 37 of the fixed platen 30 and cannot be rotated, while the top wall 63 is in the engaged state between the projection 43 and the engagement projection 41a. , Move downward together with the cap 60 with the screw engagement of the cap 60.

  As the screw engagement between the cap 60 and the fixed board 30 progresses, the stem 13 comes into contact with the recess 25 a of the nozzle 20. Further, the nozzle 20 is pressed downward by the contact protrusion 53 a of the push-down lever 50 that moves down together with the cover 40 by further screw engagement, and the stem 13 is firmly fitted into the recess 25 a of the nozzle 20. When the screw engagement between the cap 60 and the fixed board 30 is completed, as shown in FIG. 3, the lower surface of the protrusion 43 of the cover 40 contacts the upper end of the side wall 31 of the fixed board 30, and the fixed board 30 and the cover The 40 and the cap 60 are completely fixed.

  As described above, in the discharge container 1 of the present embodiment, the fixed plate 30 is fixed to the container body 10 having a substantially cylindrical shape by undercut, and the fixed plate 30 and the cap 60 are fixed by screw engagement. The rib 41b of the cover 40 is configured to be insertable into the opening 37 of the fixed board 30. When the user rotates the cap 60 in the circumferential direction to release the screw engagement, the nozzle 20 is pulled out from the stem 13 of the container body 10, and the cap 60, the cover 40, the nozzle 20, and the push-down lever 50 are moved to the container. Since it can be separated upward from the main body 10, the container main body 10 is not damaged when the cover 40 or the like is removed. Also, at the time of assembly, the cap 60, the cover 40, the nozzle 20, and the push-down lever 50 are fixed to the fixed plate 30 only when the cover 40 and the fixed plate 30 are aligned in the circumferential direction. It becomes possible to approach the main body 10. Therefore, there is no possibility that the cover 13, the nozzle 20, and the push-down lever 50 are brought close to the container body 10 without the positioning, and the stem 13 and the like are not damaged.

  In the present embodiment, the ribs 41b (convex portions) are provided on the cover 40 side, and the openings 37 (concave portions) are provided on the fixed board 30 side. However, the present invention is not limited to this mode. A convex portion may be provided on the fixed platen 30 side and a concave portion may be provided on the cover 40 side. Further, the convex portion is not limited to the configuration of the rib 41b formed on the cylindrical wall portion 41, and may be, for example, a projecting portion projecting downward. Further, the concave portion is not limited to the shape of the opening 37, but includes any form in which the convex portion can be fitted, such as a dent that does not penetrate.

  According to this embodiment, two ribs 41b are provided at symmetrical positions around the central axis O of the cover 40, and two openings 37 are provided at symmetrical positions around the central axis O of the fixed plate 30. I made it. Therefore, since it is configured to be attachable at any of two rotational positions where the position of the concave portion 25a provided in the nozzle 20 and the position of the stem 13 coincide with each other in a plan view, the front and rear directions of the cover 40 can be changed when the cover 40 is attached. This eliminates the need for matching, and can avoid complicated installation work. Note that, instead of such a symmetrical configuration, an asymmetrical configuration may be adopted, and mounting may be performed in only one direction.

  In the above-described embodiment, two sets of the rib 41b (convex portion) and the opening 37 (recess) are provided. However, the present invention is not limited to such a configuration, and only one set of the rib 41b and the opening 37 is provided. Or three or more sets may be provided.

  According to the present embodiment, the cover 40 is provided with the ribs 41b extending in the up-down direction, and the fixing plate 30 is provided with the opening 37 into which the ribs 41b can be fitted from above. The cover 40 can be easily attached to and detached from the fixed platen 30 only by moving the cover 40 in the vertical direction in a state where the screw engagement of the cover 30 is released.

  Further, according to the present embodiment, since the cover 43 is provided with the protrusion 43 and the upper surface of the protrusion 43 is configured to contact the lower surface of the top wall 63 of the cap 60, the cap 60 is directed downward with respect to the cover 40. Is restricted. With this configuration, in a state where the rib 41b of the cover 40 is not fitted into the opening 37 of the fixing plate 30, the female screw portion 61a of the cap 60 and the male screw portion 31a of the fixing plate 30 are vertically separated from each other. Screw engagement between the cap 60 and the fixed platen 30 in a state where the positioning of the cap 40 has not been performed can be prevented.

  Further, according to the present embodiment, since the unevenness of the vertical knurl 65 is formed on the outer peripheral surface of the cap 60, the vertical knurl 65 is removed when the cap 60, the cover 40, and the like are removed from the fixed plate 30. The cap 60 can be removed by rotating the cap 60 in the circumferential direction without slipping the hand by gripping. Further, the user can easily recognize that the discharge container 1 can be disassembled by rotating the longitudinal knurl 65 in the circumferential direction.

  What has been described above merely shows one embodiment of the present invention, and it goes without saying that various changes may be made within the scope of the claims.

  For example, in the present embodiment, two stems 13 are provided in the mouth 11, but the present invention is not limited to this aspect, and an arbitrary number of three or more stems 13 may be provided.

  In addition, although the push-down lever 50 is configured such that it is formed separately from the cover 40, the push-down lever 50 may be integrally formed with the cover 40. Alternatively, the pressing lever 50 may be omitted, and the nozzle 20 may be directly pressed down by a finger.

  Further, although the nozzle 20 is configured separately from the cover 40, the nozzle 20 may be integrated with the cover 40 via, for example, a hinge. Although the nozzle 20 is configured to be removed together with the cover 40 when the cover 40 is removed, the nozzle 20 may be configured to be removable before the cover 40. Further, the nozzle 20 may be configured to discharge the contents upward instead of forward.
