Mode for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be illustratively described with reference to the drawings.

[0014] As shown in FIGS. 1 to 5, in one embodiment of the present invention, a discharge container 1 includes a cylindrical mouth portion 2a centered on a central axis O, a body portion 2b whose diameter expands from the lower end of the mouth portion 2a, and a bottom portion (not shown), which are connected in this order downward, and a discharge pump 3 that is attached to the mouth portion 2a and receives an operation to discharge the content liquid in the container body 2 forward from a discharge port 5a.

[0015] In the present embodiment, the direction along the central axis O of the mouth portion 2a is referred to as the vertical direction, the direction from the mouth portion 2a toward the bottom along the vertical direction is referred to as the downward direction, the opposite direction is referred to as the upward direction, the direction along an axis P that is orthogonal to the central axis O and passes through the center of the discharge port 5a is referred to as the front-rear direction, the direction from the central axis O toward the discharge port 5a along the front-rear direction is referred to as the forward direction, the opposite direction is referred to as the rear direction, and the direction perpendicular to the vertical direction and the front-rear direction is referred to as the left-right direction. Further, regarding the nozzle member 5 described later, the direction orthogonal to the axis P of the discharge port 5a is referred to as the radial direction, and the direction that circulates around the axis P of the discharge port 5a is referred to as the circumferential direction.

[0016] The content liquid is not particularly limited, but the discharge container 1 of the present embodiment is particularly suitable when a chemical liquid such as a herbicide whose effect weakens when there is uneven coating is used as the content liquid.

[0017] The discharge pump 3 has a discharge pump body 4 having an internal flow path 4a including a suction port (not shown), a pump chamber 4a1, and a discharge port 5a, and a mounting portion 4b mounted on the mouth portion 2a, a trigger 3a that is supported by the discharge pump body 4 so as to be movable in the front-rear direction (swing in this embodiment), and receives the operation of pulling backward, and a spring 3b that biases the trigger 3a to the initial position (see FIG. 1). The pump chamber 4a1 is partitioned by a cylinder 3c and a piston 3d that slides in the cylinder 3c in conjunction with the trigger 3a. An upstream backflow prevention portion 3e that allows the flow of the content liquid from the suction port toward the pump chamber 4a1 and suppresses backflow is provided between the suction port and the pump chamber 4a1. A downstream backflow prevention portion 3f that allows the flow of the content liquid from the pump chamber 4a1 toward the discharge port 5a and suppresses backflow is provided between the pump chamber 4a1 and the discharge port 5a.

[0018] <000,0095>The internal flow path 4a of the discharge pump body 4 has a vertical flow path 4a2 extending in the vertical direction and a horizontal flow path 4a3 extending forward from the downstream end of the vertical flow path 4a2 toward the discharge port 5a. The discharge pump body 4 has a vertical flow path forming portion 4c that forms the vertical flow path 4a2 and a horizontal flow path forming portion 4d that forms the horizontal flow path 4a3, and the trigger 3a is operably supported by the horizontal flow path forming portion 4d.

[0019] A positive and negative inversion dual-use unit 3g is provided between the suction port and the pump chamber 4a1. The positive and negative inversion dual-use unit 3g allows the content liquid to pass from the suction port toward the pump chamber 4a1 in the upright posture of the discharge container 1, and sucks the content liquid in the container body 2 from the inverted suction port 3g1 in the inverted posture of the discharge container 1 and directs it toward the pump chamber 4a1. Note that the discharge pump 3 may be configured without the positive and negative inversion dual-use unit 3g.

[0020] As shown in FIG. 2, the discharge port 5a forms an X shape in a front view (when viewed from the front), and discharges the content liquid into the X-shaped region R. Forming an X shape in a front view means forming an X shape that extends细长ly along a first axis Q1 extending in a diagonally downward direction and a second axis Q2 intersecting the first axis Q1 and extending in a diagonally upward direction. In this embodiment, the first axis Q1 and the second axis Q2 are orthogonal, but it is not limited to this.

[0021] The discharge port 5a, when viewed from the front, has an X-shape with the entire port except for the central part being open, and includes a first opening 5a1 that extends elongated downward to the right toward the central part, a second opening 5a2 that extends elongated downward to the left toward the central part, a third opening 5a3 that extends elongated upward to the right toward the central part, and a fourth opening 5a4 that extends elongated upward to the left toward the central part.

[0022] As shown in Figures 2-3, the discharge pump 3 (discharge pump body 4) has a nozzle member 5 having a discharge port 5a, and the nozzle member 5 has a nozzle body 6 and a nozzle tip 7 that is attached to the nozzle body 6. As shown in Figure 4, the nozzle body 6 has a body opening 6a and a pair of body protrusions 6b, and the pair of body protrusions 6b consist of a one-side protrusion 6c that protrudes forward on one side of the body opening 6a (upper side in this embodiment) in the vertical direction, and a other-side protrusion 6d that protrudes forward on the other side of the body opening 6a (lower side in this embodiment). As shown in Figure 5, the nozzle tip 7 has a partition wall 7a and a tip opening 7b that penetrates the partition wall 7a in the front-rear direction. The discharge port 5a is formed by the gap between the pair of body protrusions 6b and the partition wall 7a when the pair of body protrusions 6b are inserted into the tip opening 7b as the nozzle tip 7 is attached to the nozzle body 6.

[0023] The nozzle body 6 includes a body wall 6e extending perpendicular to the front-rear direction, a body opening 6a provided in the body wall 6e, a pair of body protrusions 6b projecting forward from the body wall 6e, a fitting cylinder 6f extending forward from the body wall 6e radially outward from the body opening 6a and the pair of body protrusions 6b, and fitting with the outer peripheral edge of the nozzle tip 7 on its inner circumferential surface, a protective cylinder 6g extending radially outward from the fitting cylinder 6f and from the outer peripheral edge of the body wall 6e to forward of the fitting cylinder 6f, a nozzle mounting portion 6h extending rearward from the body wall 6e and attached to the tip of the lateral flow path forming portion 4d, and a flow path forming cylinder 6i extending rearward from the body wall 6e radially inward from the nozzle mounting portion 6h, and forming the tip of the lateral flow path 4a3 radially inward.

[0024] Each of the pair of main body protrusions 6b (one side protrusion 6c and the other side protrusion 6d) is fan-shaped in a front view, having a pair of radially extending circumferential end faces 6b1 and a circumferentially extending outer peripheral end face 6b2. Each of the pair of circumferential end faces 6b1 has a recess 6b3 extending radially from the radially inner end to the radially outer end with a certain circumferential depth. The pair of circumferential end faces 6b1 form a corner portion 6b4 at their radially inner ends.

[0025] The partition wall 7a of the nozzle tip 7 engages with a pair of main body protrusions 6b at the tip opening 7b. The partition wall 7a has a pair of one-side circumferential end faces 7a1 that engage with a pair of circumferential end faces 6b1 of one-side protrusion 6c, a one-side outer peripheral end face 7a2 that engages with the outer peripheral end face 6b2 of one-side protrusion 6c, a pair of other-side circumferential end faces 7a3 that engage with a pair of circumferential end faces 6b1 of the other-side protrusion 6d, and a other-side outer peripheral end face 7a4 that engages with the outer peripheral end face 6b2 of the other-side protrusion 6d. Each of the pair of one-side circumferential end faces 7a1 has a one-side recess 7a5 that extends from the radially inner end to the radially outer end with a certain circumferential depth. Each of the pair of other-side circumferential end faces 7a3 has a other-side recess 7a6 that extends from the radially inner end to the radially outer end with a certain circumferential depth.

[0026] The main body opening 6a extends from the recesses 6b3 of the pair of circumferential end faces 6b1 of the protrusion 6c on one side to the recesses 6b3 of the pair of circumferential end faces 6b1 of the protrusion 6d on the other side.

[0027] The discharge port 5a consists of a gap (first opening 5a1 and second opening 5a2) formed by the recesses 6b3 of a pair of circumferential end faces 6b1 of one side protrusion 6c and the one-side recess 7a5 of a pair of one-side circumferential end faces 7a1 of the partition wall 7a, and a gap (third opening 5a3 and fourth opening 5a4) formed by the recesses 6b3 of a pair of circumferential end faces 6b1 of the other side protrusion 6d and the other-side recess 7a6 of a pair of other-side circumferential end faces 7a3 of the partition wall 7a.

[0028] The partition wall 7a has a substantially circular closing portion 7a7 in a front view that connects to the radially inner ends of a pair of one-sided circumferential end faces 7a1 and the radially inner ends of a pair of other-sided circumferential end faces 7a3, closing off the central part of the tip opening 7b. The nozzle tip 7 has a tip projection 7c that protrudes rearward from the partition wall 7a and fits into the body opening 6a when the nozzle tip 7 is attached to the nozzle body 6. Note that the partition wall 7a is not limited to having a closing portion 7a7.

[0029] In this embodiment, the nozzle member 5 is arranged so that a pair of main body protrusions 6b are aligned vertically, but it is not limited to this arrangement; they may also be arranged horizontally.

[0030] The nozzle body 6 and the nozzle tip 7 are each integrally molded, for example, by injection molding. The materials for the nozzle body 6 and the nozzle tip 7 are each, for example, resin.

[0031] In the upright position, the discharge container 1 expands and contracts the pump chamber 4a1 by pulling the trigger 3a against the biasing force of the spring 3b and then releasing it, thereby sending the contents of the container body 2 through the suction port, the upstream backflow suppression section 3e, the pump chamber 4a1, and the downstream backflow suppression section 3f in that order to the discharge port 5a and ejecting it. In the inverted position, the discharge container 1 expands and contracts the pump chamber 4a1 by pulling the trigger 3a against the biasing force of the spring 3b and then releasing it, thereby sending the contents of the container body 2 through the inverted suction port 3g1, the upstream backflow suppression section 3e, the pump chamber 4a1, and the downstream backflow suppression section 3f in that order to the discharge port 5a and ejecting it.

[0032] When the trigger 3a is pulled, the pump chamber 4a1 contracts and becomes pressurized. This pressurization opens the elastic valve in the downstream backflow suppression section 3f, and the contents of the pump chamber 4a1 are pumped through the downstream backflow suppression section 3f to the discharge port 5a. At this time, backflow of the contents of the pump chamber 4a1 into the container body 2 is suppressed by the seating of the ball valve in the upstream backflow suppression section 3e. When the pull operation on the trigger 3a is released, the pump chamber 4a1 expands and becomes depressurized. This depressurization opens the ball valve in the upstream backflow suppression section 3e, and the contents of the container body 2 are drawn into the pump chamber 4a1 through the upstream backflow suppression section 3e. At this time, backflow of the fluid downstream of the downstream backflow suppression section 3f into the pump chamber 4a1 is suppressed by the seating of the elastic valve in the downstream backflow suppression section 3f. Note that the upstream backflow suppression section 3e is not limited to a ball valve configuration. Furthermore, the downstream backflow suppression section 3f is not limited to being composed of an elastic valve. Also, the upstream backflow suppression section 3e is not limited to being composed of a ball valve.

[0033] According to this embodiment, the liquid contents are discharged into an X-shaped region R by the X-shaped discharge port 5a, so unevenness in the concentration of the liquid contents in the vertical and horizontal directions within the discharged region can be suppressed. Therefore, when applying the liquid contents while moving the discharge port 5a in the vertical or horizontal direction relative to the application target, uneven application can be suppressed.

[0034] Furthermore, according to this embodiment, since the X-shaped discharge port 5a is blocked in the center by the blocking portion 7a7, the liquid contents are not discharged in a concentrated manner in the center of the X-shaped region R, thus further suppressing uneven coating.

[0035] Furthermore, according to this embodiment, the X-shaped discharge port 5a, which is difficult to form when manufacturing the nozzle member 5 as a single molded product, can be easily formed by attaching the nozzle tip 7 to the nozzle body 6.

[0036] Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and the embodiments described above can be modified in various ways without departing from the spirit of the present invention.
