Description

[Technical field]

[0001] The present invention relates to a trigger dispenser. [Background technology]

[0002] Trigger-type liquid ejectors capable of switching ejection patterns are known (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2011-177630 A Summary of the Invention [Problem to be solved by the invention]

[0004] The trigger type liquid ejector of Patent Document 1 has a structure that allows switching of ejection patterns such as mist state, spray angle, etc. However, in a trigger type liquid ejector, it is desired to be able to switch between a state in which liquid is ejected in a straight line in order to eject the liquid relatively far away, and a state in which liquid is ejected in a shower in order to eject the liquid relatively close by, for example.

[0005] In view of the above circumstances, one aspect of the present invention aims to provide a trigger-type ejector that can switch between a state in which liquid is ejected in a straight line and a state in which liquid is ejected in a shower-like manner. [Means for solving the problem]

[0006] One aspect of the trigger type dispenser of the present invention comprises a dispenser body attached to a container body that contains liquid, a nozzle member having a receiving hole that opens toward the front and rotatably attached to the dispenser body, and a dispenser member located within the receiving hole and attached to the nozzle member, the dispenser body having a vertical supply tube portion that sucks up liquid in the container body, and a trigger portion that is arranged so as to be movable rearward in a forward biased state, and a trigger mechanism that causes liquid to flow from within the vertical supply tube portion toward the nozzle member by the rearward movement of the trigger portion, and the dispenser member has a first discharge port that opens toward the front. and a plurality of grooves; is established, The openings of the plurality of grooves are closed by the inner surface of the accommodation hole, A plurality of second outlets opening forward are provided between the discharge member and the inner surface of the accommodating hole, and a first flow path capable of communicating the inside of the discharger body with the first outlet and a second flow path capable of communicating the inside of the discharger body with the plurality of second outlets are provided, and by rotating the nozzle member, it is possible to switch between a first state in which the inside of the discharger body is connected to the first outlet by the first flow path and the second flow path is blocked, and a second state in which the inside of the discharger body is connected to the plurality of second outlets by the second flow path and the first flow path is blocked.

[0007] According to one aspect of the present invention, the trigger type dispenser can be switched between a first state in which the inside of the dispenser body is connected to the first outlet by the first flow path and the second flow path is blocked, and a second state in which the inside of the dispenser body is connected to the multiple second outlets by the second flow path and the first flow path is blocked, by rotating the nozzle member. Therefore, by setting the state of the trigger type dispenser to the first state, one liquid stream can be discharged in a straight line from one first outlet, and by setting the state of the trigger type dispenser to the second state, liquid can be discharged in a shower-like manner as multiple liquid streams from the multiple second outlets. Therefore, according to one aspect of the present invention, a trigger type dispenser that can be switched between a state in which liquid is discharged in a straight line and a state in which liquid is discharged in a shower-like manner is obtained.

[0008] In the second state, the liquid is discharged as multiple liquid streams, so the force of the discharged liquid is weaker than in the first state in which one liquid stream is discharged from one first outlet. Therefore, if the state of the trigger-type dispenser is set to the second state, it is possible to prevent the liquid from scattering around even when the liquid is sprayed on a relatively nearby target. In the second state, the liquid can be sprayed over a relatively wide area by multiple liquid streams. In addition, since multiple liquid streams can be discharged from multiple second outlets in the second state, it is possible to prevent the amount of liquid sprayed on the target from being insufficient compared to when the liquid becomes mist-like. As described above, according to one aspect of the present invention, a trigger-type dispenser is obtained that can spray a sufficient amount of liquid over a relatively wide area while preventing the liquid from scattering.

[0009] Furthermore, by setting the state of the trigger-type dispenser to the first state, the force of the dispensed liquid can be made relatively strong, making it possible to spray the liquid on targets that are relatively far away. Therefore, by setting the trigger-type dispenser to the first state when spraying liquid on targets that are relatively far away, and setting the trigger-type dispenser to the second state when spraying liquid on targets that are relatively close, it is possible to suitably spray the liquid on targets that are relatively far away and targets that are relatively close.

[0010] Also, for example, when both the first outlet and the multiple second outlets are formed in the discharge member, the number of holes formed in the discharge member to form each outlet increases, and the molding accuracy of each outlet may decrease. Specifically, burrs or the like are likely to occur in the holes formed to form each outlet, and the molding accuracy of each outlet may decrease. In contrast, according to one aspect of the present invention, the multiple second outlets are provided between the discharge member and the inner surface of the accommodation hole. Therefore, compared to the case where both the first outlet and the multiple second outlets are provided in the discharge member, the number of holes formed in the discharge member can be reduced. This improves the molding accuracy of the first outlet and the multiple second outlets. Therefore, the discharge direction of the liquid discharged from the first outlet and the multiple second outlets and the momentum of the discharged liquid can be stabilized.

[0011] The nozzle member may be rotated to be switchable to a third state in which both the first flow path and the second flow path are blocked. According to this configuration, by setting the trigger-type dispenser in the third state when not in use, it is possible to prevent liquid from being unintentionally dispensed when, for example, the trigger portion is pulled by mistake.

[0012] The ejector main body has a protruding tubular portion that protrudes forward and has a closed front end, and an outer tubular portion that surrounds the protruding tubular portion, the nozzle member has a fitting tubular portion that is fitted onto the protruding tubular portion, and an intermediate tubular portion that is disposed between the fitting tubular portion and the outer tubular portion and has a rear end that is connected to an outer circumferential surface of the fitting tubular portion, the intermediate tubular portion forms at least a part of the accommodating hole, the front end of the fitting tubular portion is located forward of the protruding tubular portion and opens forward, the ejection member is attached to the front end of the fitting tubular portion, a first communication hole that communicates with the interior of the ejector main body is provided in a portion of the protruding tubular portion where the fitting tubular portion is fitted, and the intermediate tubular portion has a first communication hole that communicates with the interior of the ejector main body, and the nozzle member has a first communication hole that communicates with the interior of the ejector main body and a second communication hole that communicates with the interior of the ejector main body. A second communication hole is provided that communicates between the inside of the outer tube portion and the inside of the intermediate tube portion, and in the first state, the first communication hole communicates with the first outlet through the inside of a part of the fitting tube portion that is located forward of the protruding tube portion, thereby forming the first flow path that communicates between the inside of the ejector body and the first outlet, and in the second state, the first communication hole communicates with a space located inside the outer tube portion and outside the fitting tube portion and the intermediate tube portion, and with the multiple second outlets through the second communication hole, thereby forming the second flow path that communicates between the inside of the ejector body and the multiple second outlets. With this configuration, each flow path can be configured appropriately for each of the first and second states, and it is possible to appropriately switch between the first state in which liquid is ejected from the first outlet and the second state in which liquid is ejected from the multiple second outlets.

[0013] A first communication groove is provided on the outer peripheral surface of the protruding tubular portion in a portion facing the inner peripheral surface of the fitting tubular portion, the first communication groove communicating with the first discharge port through the inside of a portion of the fitting tubular portion located forward of the protruding tubular portion, and a second communication groove opening at the rear end of the fitting tubular portion and communicating with the space, and a third communication groove communicating with the first communication hole are provided on the inner peripheral surface of the fitting tubular portion in a portion facing the outer peripheral surface of the protruding tubular portion, and in the first state, the first communication groove and the third communication groove communicate with each other, and the first communication hole and the second communication groove are blocked, and in the second state, the first communication groove and the third communication groove are blocked, and the first communication hole and the second communication groove communicate with each other. According to this configuration, by providing the first communication groove, the second communication groove, and the third communication groove, the communication state of the first communication hole and the second communication hole can be easily switched by rotating the nozzle member. Therefore, the first state and the second state can be switched more preferably. In addition, the second communication groove makes it easy to provide a flow path portion in the second flow path through which liquid flows backward. Effect of the Invention

[0014] According to one aspect of the present invention, there is provided a trigger-type dispenser that can be switched between a state in which liquid is dispensed in a straight line and a state in which liquid is dispensed in a shower shape. [Brief description of the drawings]

The trigger type dispenser 3 includes a dispenser body 10, a nozzle member 20, a dispenser member 30, and an inverted forward adapter 40.

[0018] The ejector body 10 is attached to the container body 2. The ejector body 10 has a vertical supply tube portion 11 that sucks up the liquid L in the container body 2, an injection tube portion 12 that guides the liquid L sucked up by the vertical supply tube portion 11 to a nozzle member 20, a connecting member 50 that connects the injection tube portion 12 and the nozzle member 20, and a trigger mechanism 14 that circulates the liquid L inside the vertical supply tube portion 11, the injection tube portion 12, and the connecting member 50.

[0019] The vertical supply tube portion 11 is a cylindrical portion extending in one direction as a whole. The vertical supply tube portion 11 is cylindrical and disposed about an axis O shown imaginarily in FIG. 1. The vertical supply tube portion 11 has a topped cylindrical outer tube 15 and an inner tube 16 fitted into the outer tube 15. The outer tube 15 and the inner tube 16 are disposed coaxially with the axis O.

[0020] In the following description, the direction along the axis O is referred to as the vertical direction, and is shown as the Z-axis direction in each drawing. The vertical direction is one direction in which the vertical supply tube portion 11 extends. In the upright position of the discharge container 1, the vertical direction from the trigger-type dispenser 3 toward the container body 2 (-Z direction) is referred to as the downward direction, and the vertical direction from the container body 2 toward the trigger-type dispenser 3 (+Z direction) is referred to as the upward direction. Moreover, of the directions perpendicular to the axis O, one direction is called the front-rear direction, and is shown as the Y-axis direction in each drawing. The direction in which the injection tube section 12 extends from the vertical supply tube section 11 in the front-rear direction (+Y direction) is called the front, and the opposite direction (-Y direction) is called the rear. Moreover, of the directions perpendicular to the axis O, the direction perpendicular to the front-rear direction is called the left-right direction, and is shown as the X-axis direction in each drawing.

[0021] In this embodiment, the axis O of the vertical supply tube portion 11 is disposed at a position closer to the rear side than the container axis that passes through the center of the mouth portion 2a of the container body 2 in the up-down direction. Outer cylinder 15 has large diameter portion 15a and small diameter portion 15b that is disposed above large diameter portion 15a and has smaller inner and outer diameters than large diameter portion 15a. The inner cylinder 16 has a large diameter portion 16a and a small diameter portion 16b that is disposed above the large diameter portion 16a and has smaller inner and outer diameters than the large diameter portion 16a. The large diameter portion 16a is fitted into the large diameter portion 15a of the outer cylinder 15. The large diameter portion 16a protrudes downward beyond the large diameter portion 15a. The small diameter portion 16b is fitted into the small diameter portion 15b of the outer cylinder 15.

[0022] An annular flange 16e is formed on a portion of the large diameter portion 16a of the inner cylinder 16 that is located below the large diameter portion 15a of the outer cylinder 15. The flange 16e is disposed on the upper opening edge of the mouth 2a of the container body 2 via a packing 17. The inner peripheral edge of the upper end of an attachment cap 18 for attaching the trigger-type dispenser 3 to the container body 2 engages from above with the outer peripheral edge of the flange 16e.

[0023] The mounting cap 18 is formed in a cylindrical shape extending in the vertical direction. The mounting cap 18 is mounted to the mouth portion 2a with the flange portion 16e and the packing 17 sandwiched between the mounting cap 18 and the upper end opening edge of the mouth portion 2a. In this embodiment, the mounting cap 18 is, for example, screwed to the mouth portion 2a. By mounting the mounting cap 18 to the mouth portion 2a, the entire dispenser body 10 is mounted to the mouth portion 2a of the container body 2 via the mounting cap 18.

[0024] An outer through hole 15c penetrating the wall of small diameter portion 15b in the front-rear direction is formed in the front portion of the upper end of small diameter portion 15b of outer cylinder 15. An inner through hole 16c penetrating the wall of small diameter portion 16b in the front-rear direction is formed in the front portion of the upper end of small diameter portion 16b of inner cylinder 16 and located rearward of outer through hole 15c.

[0025] The vertical supply tube portion 11 has an internal flow passage 19a. The internal flow passage 19a is an internal space located inside the inner tube 16. The injection tube portion 12 extends forward from the upper end of the vertical supply tube portion 11. The injection tube portion 12 is cylindrical and opens forward. The rear end of the injection tube portion 12 communicates with a portion of the internal flow passage 19a of the vertical supply tube portion 11 that is located above a ball valve 60 (described later) through an outer through hole 15c and an inner through hole 16c. A cylinder tube portion 13 is provided below the injection tube portion 12 and above the mounting cap 18. The cylinder tube portion 13 protrudes forward from the vertical supply tube portion 11 and opens forward.

[0026] Connecting member 50 is attached to the front end of injection tube portion 12. As shown in Fig. 2, connecting member 50 has an annular portion 51 having a circular ring shape surrounding rotation axis R extending in the front-rear direction, a connecting tube portion 52 extending rearward from annular portion 51, a protruding tube portion 53 protruding forward from annular portion 51, and an outer tube portion 54 protruding forward from annular portion 51 and surrounding protruding tube portion 53. The rotation axis R is an imaginary axis shown in each drawing. The rotation axis R is disposed slightly shifted downward with respect to the central axis of the injection tube portion 12. In the following description, the direction intersecting the rotation axis R when viewed from the front-rear direction is referred to as the radial direction, and the direction rotating around the rotation axis R is referred to as the circumferential direction.

[0027] The connecting cylinder portion 52 is fitted onto the outside of the injection cylinder portion 12. In this way, the connecting member 50 is connected to the injection cylinder portion 12. The protruding tube portion 53 protrudes forward from the radial inner edge of the annular portion 51. The protruding tube portion 53 is cylindrical with a closed front end and an open rear end. The protruding tube portion 53 is arranged coaxially with the rotation axis R. The rear end of the protruding tube portion 53 is arranged opposite to the front end of the injection tube portion 12. The inside of the protruding tube portion 53 communicates with the inside of the injection tube portion 12. The protruding tube portion 53 has a large diameter tube portion 53a extending forward from the annular portion 51 and a small diameter tube portion 53b connected to the front of the large diameter tube portion 53a via a step. The small diameter tube portion 53b has an inner diameter and an outer diameter smaller than those of the large diameter tube portion 53a. The front end of the small diameter tube portion 53b is the front end of the protruding tube portion 53.

[0028] A first communication hole 81 that communicates with the inside of the dispenser body 10 is provided in a portion of the protruding tube portion 53 on which a fitting tube portion 23 (described later) is fitted. In this embodiment, the first communication hole 81 is provided in a lower wall portion at the front end portion of the large diameter tube portion 53a. The first communication hole 81 penetrates the lower wall portion of the large diameter tube portion 53a in the vertical direction. The first communication hole 81 communicates with the inside of the injection tube portion 12 via the inside of the protruding tube portion 53.

[0029] A first communication groove 83 extending in the front-rear direction is provided in a portion of the outer circumferential surface of the protruding tube portion 53 that faces the inner circumferential surface of the fitting tube portion 23 described later. In this embodiment, the first communication groove 83 is provided in the upper wall portion at the front end portion of the small diameter tube portion 53b. The first communication groove 83 is recessed downward from the upper end portion of the small diameter tube portion 53b. The first communication groove 83 opens forward. The rear end portion of the first communication groove 83 is closed. The surface located at the rear end portion of the inner surface of the first communication groove 83 is inclined toward the rear as it goes upward. The first communication groove 83 communicates with a first discharge port 71 described later through the inside of a portion of the fitting tube portion 23 described later that is located forward of the protruding tube portion 53.

[0030] The outer cylinder portion 54 extends forward from the radial outer edge of the annular portion 51. The front end of the outer cylinder portion 54 is located forward of the front end of the protruding cylinder portion 53. The outer cylinder portion 54 has a small diameter cylinder portion 54a extending forward from the annular portion 51 and a large diameter cylinder portion 54b connected to the front of the small diameter cylinder portion 54a via a step. The large diameter cylinder portion 54b has an inner diameter and an outer diameter larger than those of the small diameter cylinder portion 54a. The front end of the large diameter cylinder portion 54b is the front end of the outer cylinder portion 54. An engagement protrusion 54c is provided on the outer peripheral surface of the large diameter cylinder portion 54b.

[0031] 1, the trigger mechanism 14 has a trigger portion 14a, a cylinder 14b, and a piston 14c. The trigger mechanism 14 is capable of circulating the liquid L from the inside of the internal flow path 19a of the vertical supply tube portion 11 through the inside of the injection tube portion 12 toward the nozzle member 20 by the rearward movement (swinging) of the trigger portion 14a. The cylinder 14b is fitted into the cylinder tube portion 13. The cylinder 14b is formed in a bottomed tube shape that is open at the front and closed at the rear. The cylinder 14b communicates with a portion of the internal flow passage 19a in the vertical supply tube portion 11 that is located above a ball valve 60, which will be described later.

[0032] Trigger portion 14a is disposed in front of vertical supply tube portion 11 so as to be movable rearward in a forward biased state. Trigger portion 14a is formed to extend in the up-down direction and disposed below injection tube portion 12. An upper end portion of trigger portion 14a is journaled on injection tube portion 12 so as to be swingable in the front-rear direction. An upper portion of trigger portion 14a is disposed in front of cylinder 14b.

[0033] The piston 14c is disposed inside the cylinder 14b so as to be movable in the front-rear direction. The piston 14c is movable in the front-rear direction in conjunction with the swinging of the trigger portion 14a. As a result, the inside of the cylinder 14b is pressurized and depressurized as the piston 14c moves in the front-rear direction. The piston 14c is formed in a topped cylindrical shape that opens to the rear and is closed at the front.

[0034] The piston 14c is biased forward together with the trigger portion 14a by the elastic restoring force (biasing force) of the biasing member 14d. As the trigger portion 14a swings backward, the piston 14c moves backward and is pushed into the cylinder 14b. When the trigger portion 14a is in the forward-most swing position, the piston 14c is correspondingly located in the forward-most position. The biasing member 14d is disposed between the injection tube portion 12 and the trigger portion 14a, and biases the trigger portion 14a forward.

[0035] In this specification, "the trigger portion and the piston move in the front-rear direction" means that the trigger portion and the piston move so that their positions in the front-rear direction change, and also includes the trigger portion and the piston moving at an angle relative to the front-rear direction. For example, the trigger portion and the piston may move forward and backward from a diagonally upward front direction to a diagonally downward rear direction. Also, for example, the trigger portion and the piston may move forward and backward from a diagonally downward front direction to a diagonally upward rear direction.

[0036] The dispenser body 10 further includes a ball valve 60 and a storage valve 61 provided in the small diameter portion 16 b of the inner cylinder 16 in the vertical supply cylinder portion 11 . The ball valve 60 serves as a check valve that blocks communication between the inside of the container body 2 and the inside of the cylinder 14b through the internal flow path 19a when the inside of the cylinder 14b is pressurized, and allows communication between the inside of the container body 2 and the inside of the cylinder 14b through the inner tube 16 by displacing upward when the inside of the cylinder 14b is depressurized.

[0037] The storage valve 61 is disposed above the ball valve 60. The storage valve 61 is disposed inside the upper end portion of the small diameter portion 16b of the inner cylinder 16. The storage valve 61 is a check valve that allows the supply of liquid L from the inside of the internal flow path 19a to the inside of the injection cylinder portion 12, and prevents the liquid L from flowing back from the inside of the injection cylinder portion 12 to the inside of the cylinder 14b. The storage valve 61 is not limited to a valve having the above-mentioned function as a check valve, and may be, for example, a pressure storage valve that opens when the pressure in the portion of the internal flow path 19a located above the ball valve 60 reaches a predetermined pressure, thereby allowing the supply of pressurized liquid L from the internal flow path 19a to the injection tube portion 12.

[0038] The normal and inverted adapter 40 is an adapter that enables the discharge of the liquid L in the container body 2 when the discharge container 1 is in either the normal or inverted position. The normal and inverted adapter 40 is disposed inside the mounting cap 18. The normal and inverted adapter 40 is disposed below the vertical supply tube portion 11 along the axis O, and is connected to the inner tube 16 of the vertical supply tube portion 11. As a result, the normal and inverted adapter 40 is disposed inside the mounting cap 18 in a state where it is integrally assembled below the vertical supply tube portion 11. The normal and inverted adapter 40 has an adapter main body 43 connected below the inner tube 16, and a ball valve 44 housed in the adapter main body 43.

[0039] The adapter body 43 defines a first space S1 that connects the inside of the container body 2 to the inside of the internal flow path 19a of the inner tube 16 through the upright inlet 41, and a second space S2 that connects the inside of the container body 2 to the first space S1 through the inverted inlet 42. The ball valve 44 blocks communication between the first space S1 and the second space S2 when the container body 2 is upright with the dispenser main body 10 attached to the container body 2, and connects the first space S1 and the second space S2 when the container body 2 is inverted.

[0040] The nozzle member 20 is rotatably attached to the discharger body 10. More specifically, the nozzle member 20 is rotatably attached to a connecting member 50 of the discharger body 10. The nozzle member 20 is connected to the injection tube portion 12 via the connecting member 50. The nozzle member 20 is rotatable around a rotation axis R extending in the front-rear direction. As shown in FIG. 2, the nozzle member 20 has a front wall portion 21, a mounting tube portion 22 extending rearward from the front wall portion 21, a fitting tube portion 23 extending in the front-rear direction on the radial inner side of the mounting tube portion 22, an intermediate tube portion 24 located radially between the fitting tube portion 23 and the mounting tube portion 22 and extending in the front-rear direction, and a holding tube portion 26 protruding rearward from the front wall portion 21.

[0041] The front wall 21 is plate-shaped with a plate surface facing the front-rear direction. The front wall 21 is located in front of the outer tube 54. As shown in FIG. 3, the front wall 21 is square-shaped with rounded corners when viewed from the front. A rotation axis R passes through the center of the front wall 21 in the up-down and left-right directions. A storage hole 25 that opens toward the front is provided in the center of the front wall 21 when viewed from the front. The storage hole 25 is recessed rearward from the front surface of the front wall 21. The storage hole 25 is a circular hole that is arranged coaxially with the rotation axis R. As shown in FIG. 2, the inner diameter of the front end of the storage hole 25 increases toward the front. The discharge member 30 is stored in the storage hole 25.

[0042] 3, front wall portion 21 has four printed portions 21a, 21b, 21c, and 21d. The four printed portions 21a, 21b, 21c, and 21d are arranged at equal intervals in the circumferential direction on the radial outside of accommodation hole 25. The four printed portions 21a, 21b, 21c, and 21d are provided on the radial inside of each side of front wall portion 21, which has a square shape with rounded corners when viewed from the front.

[0043] The characters "Stop" are printed on the printed portion 21a and the printed portion 21b. The printed portion 21a and the printed portion 21b are arranged on opposite sides of the rotation axis R in the radial direction. The characters "Straight" are printed on the printed portion 21c. The characters "Shower" are printed on the printed portion 21d. The printed portion 21c and the printed portion 21d are arranged on opposite sides of the rotation axis R in the radial direction. The printing on each of the printed portions 21a, 21b, 21c, and 21d is arranged in the correct vertical direction when each of the printed portions 21a, 21b, 21c, and 21d is positioned above the discharge member 30 housed in the housing hole 25. In the example of FIG. 3, the printed portion 21a is positioned above the discharge member 30, and the printing on the printed portion 21a is arranged in the correct vertical direction. In the example of Figure 3, the character "STOP" printed in printed section 21b is upside down in the vertical direction, while the character "STRAIGHT" printed in printed section 21c and the character "SHOWER" printed in printed section 21d are tilted 90 degrees left to right.

[0044] As shown in FIG. 2, the mounting tube portion 22 is disposed coaxially with the rotation axis R and is tubular and opens rearward. The mounting tube portion 22 is fitted onto the outer tube portion 54 of the connecting member 50. More specifically, the mounting tube portion 22 is fitted onto the large diameter tube portion 54b of the outer tube portion 54. The mounting tube portion 22 extends rearward beyond the large diameter tube portion 54b. An engagement protrusion 22a is provided on the inner peripheral surface of the mounting tube portion 22. The engagement protrusion 22a engages with the engagement protrusion 54c of the outer tube portion 54 from the rear.

[0045] The fitting tubular portion 23 is arranged coaxially with the rotation axis R and is cylindrical with openings on both front and rear sides. The fitting tubular portion 23 is fitted onto the protruding tubular portion 53 of the connecting member 50. The front end of the fitting tubular portion 23 is located forward of the protruding tubular portion 53 and opens forward.

[0054] The retaining tube portion 26 is located radially between the mounting tube portion 22 and the intermediate tube portion 24. The retaining tube portion 26 is arranged coaxially with the rotation axis R and has a cylindrical shape that opens to the rear. The rear end portion of the retaining tube portion 26 is located forward of the rear end portion of the intermediate tube portion 24. The front end portion of the outer tube portion 54 of the connecting member 50 is fitted onto the retaining tube portion 26.

[0055] The discharge member 30 is located in the accommodation hole 25. The discharge member 30 is a cylindrical member that is disposed coaxially with the rotation axis R and opens rearward. The discharge member 30 is fitted into the accommodation hole 25. The discharge member 30 is attached to the nozzle member 20. In this embodiment, the discharge member 30 is attached to the front end of the fitting tube portion 23. The discharge member 30 has a front wall portion 31 disposed facing the front of the fitting tube portion 23, a peripheral wall portion 32 extending rearward from the front wall portion 31 and fitted externally to the fitting tube portion 23, and a discharge tube portion 33 extending rearward from the front wall portion 31 radially inward of the peripheral wall portion 32.

[0056] The front wall portion 31 is in the shape of a disk and is arranged coaxially with the rotation axis R. The front wall portion 31 is arranged at the same position as the front wall portion 21 of the nozzle member 20 in the front-rear direction. The front wall portion 31 is provided with a first discharge port 71 that opens forward. The first discharge port 71 is a circular hole that is arranged coaxially with the rotation axis R. The first discharge port 71 penetrates the front wall portion 31 in the front-rear direction. The front end portion of the fitting tube portion 23 contacts the rear surface of the front wall portion 31. The first discharge port 71 is an outlet from which the liquid L is discharged in the direct irradiation state SB described later. The peripheral wall portion 32 extends rearward from the radial outer edge of the front wall portion 31. The rear end portion of the peripheral wall portion 32 is located forward of the front end portion of the protruding tube portion 53. The outer diameter of the peripheral wall portion 32 decreases toward the rear. The outer peripheral surface of the peripheral wall portion 32 has a shape similar to the outer peripheral surface of a truncated cone whose outer diameter decreases toward the rear.

[0057] A plurality of grooves 34 are provided on the outer peripheral surface of the peripheral wall portion 32. The plurality of grooves 34 extend in the front-rear direction and open on both sides in the front-rear direction. More specifically, the plurality of grooves 34 extend in the front-rear direction at an inclination toward the radially outward position toward the front side. As shown in FIG. 3, the plurality of grooves 34 are provided at equal intervals around the circumference in the circumferential direction. The plurality of grooves 34 surround the first discharge port 71. In this embodiment, eight grooves 34 are provided. In a cross section perpendicular to the direction in which the plurality of grooves 34 extend, the shape of the plurality of grooves 34 is a semicircular shape that is convex radially inward.

[0058] The radially outer openings of the grooves 34 are closed by the inner circumferential surface of the accommodation hole 25. As a result, a plurality of second outlets 72 that open forward are provided between the discharge member 30 and the inner surface of the accommodation hole 25. The second outlets 72 are provided at equal intervals around the circumference. The second outlets 72 surround the first outlet 71. In this embodiment, eight second outlets 72 are provided. The second outlets 72 are substantially semicircular in shape that protrudes radially inward when viewed from the front. The opening area of ​​each of the second outlets 72 is smaller than the opening area of ​​the first outlet 71. The second outlets 72 are outlets from which the liquid L is discharged in the shower state SC described later.

[0059] As shown in FIG. 2, the discharge tube portion 33 is disposed coaxially with the rotation axis R and has a cylindrical shape that opens rearward. The discharge tube portion 33 is fitted into the small diameter tube portion 23a of the fitting tube portion 23. The rear end portion of the discharge tube portion 33 is located rearward of the rear end portion of the peripheral wall portion 32. The rear end portion of the discharge tube portion 33 is disposed in front of the protruding tube portion 53 so as to face the protruding tube portion 53 with a gap therebetween. The outer circumferential surface of the discharge tube portion 33 is provided with an engagement recess 33a with which the engagement protrusion 23d of the fitting tube portion 23 is engaged. The inside of the fitting tube portion 23 is communicated with the first discharge port 71 and the first communication groove 83.

[0060] Next, a case where the trigger type dispenser 3 is used will be described. It is assumed that the liquid L is filled into each part of the trigger type dispenser 3 by operating the trigger portion 14a multiple times. It is also assumed that the state of the trigger type dispenser 3 is the direct exposure state SB or the shower state SC, which will be described later. When the trigger portion 14a is pulled backward against the biasing force of the biasing member 14d, the piston 14c moves backward from the frontmost position, and the inside of the cylinder 14b is pressurized. As a result, the liquid L in the cylinder 14b is supplied to the inside of the inner tube 16 of the vertical supply tube portion 11, i.e., into the internal flow path 19a. Specifically, the liquid L in the cylinder 14b is supplied to a portion of the internal flow path 19a that is located above the ball valve 60. As a result, the supplied liquid L presses the ball valve 60 downward and pushes up the storage valve 61.

[0061] Therefore, the liquid L in the internal flow path 19a can be circulated toward the nozzle member 20 through the injection tube portion 12. Therefore, the liquid L can be discharged forward from the first discharge port 71 or the plurality of second discharge ports 72. The state when the liquid L is discharged from each discharge port will be described in detail later. In this embodiment, since the normal / inverted adapter 40 is provided, the liquid L can be discharged whether the discharge container 1 is in the normal or inverted position.

[0062] Next, the operation of switching the discharge state of the trigger type discharger 3 will be described. The trigger type discharger 3 can be switched between a discharge-disabled state (third state) SA, a direct-ray state (first state) SB, and a shower state (second state) SC by rotating the nozzle member 20 about the rotation axis R. Figures 2 and 3 show the discharge-disabled state SA. Figure 4 shows the direct-ray state SB. Figure 5 shows the shower state SC.

[0063] As shown in FIG. 4, the direct irradiation state SB is a state in which the liquid L can be ejected from the first ejection port 71. The trigger-type ejector 3 is in the direct irradiation state SB when the printed portion 21c of the nozzle member 20 on which "direct" is printed is positioned above the ejection member 30. In the direct irradiation state SB, the liquid L ejected from the first ejection port 71 becomes a single liquid flow F1 that is sprayed straight forward. In the direct irradiation state SB, the third communication groove 85 is located radially outside (upper side) of the first communication groove 83 in the protruding tube portion 53 and communicates with the first communication groove 83. In the direct irradiation state SB of this embodiment, the rear end of the first communication groove 83 and the front end of the third communication groove 85 are connected, and the first communication groove 83 and the third communication groove 85 communicate with each other. In the direct irradiation state SB, the second communication groove 84 is disposed at a circumferential position different from that of the first communication hole 81, and the first communication hole 81 and the second communication groove 84 are blocked from each other.

[0064] In the direct shot state SB, liquid L flowing forward inside the injection tube portion 12 by the operation of the trigger portion 14a described above flows from inside the injection tube portion 12 into the protruding tube portion 53, and flows into the space S3 from the first communication hole 81. The liquid L that flows into the space S3 flows through the third communication groove 85 and the first communication groove 83 in this order, and flows into the inside of a portion of the fitting tube portion 23 that is located forward of the protruding tube portion 53. The liquid L that flows into the inside of the portion of the fitting tube portion 23 that is located forward of the protruding tube portion 53 flows into the discharge tube portion 33 of the discharge member 30, and is discharged forward as a liquid flow F1 from the first discharge port 71 that communicates with the inside of the discharge tube portion 33.

[0065] In this way, in the direct shot state SB, the first communication hole 81 communicates with the first discharge port 71 through the inside of the fitting tube portion 23 located forward of the protruding tube portion 53, thereby forming a first flow path 91 that communicates the inside of the dispenser body 10 with the first discharge port 71. In other words, the trigger-type dispenser 3 is provided with a first flow path 91 that can communicate the inside of the dispenser body 10 with the first discharge port 71. In this embodiment, the first flow path 91 is formed by the first communication hole 81, the space S3, the third communication groove 85, the second communication groove 84, the inside of the fitting tube portion 23 located forward of the protruding tube portion 53, and the inside of the discharge tube portion 33. The inside of the dispenser body 10 includes the inside of the injection tube portion 12 and the inside of the protruding tube portion 53.

[0066] As shown in Fig. 5, the shower state SC is a state in which the liquid L can be discharged from the second outlets 72. The trigger-type discharger 3 enters the shower state SC when the printed portion 21d of the nozzle member 20 on which "SHOWER" is printed is positioned above the discharge member 30. In the shower state SC, the liquid L discharged from each of the second outlets 72 becomes a single liquid stream F2 that is sprayed in a direction inclined radially outward relative to the front. That is, in the shower state SC, multiple liquid streams F2 arranged at equal intervals in the circumferential direction are sprayed forward while spreading radially outward.

[0067] In the shower state SC, the second communication groove 84 is located radially outward (lower) from the first communication hole 81 in the protruding cylindrical portion 53, and communicates with the first communication hole 81. In this embodiment, in the shower state SC, the rear end of the first communication hole 81 and the front end of the second communication groove 84 are connected, and the first communication hole 81 and the second communication groove 84 communicate with each other. In the shower state SC, the third communication groove 85 is located at a different circumferential position from the first communication groove 83, and the first communication groove 83 and the third communication groove 85 are blocked from each other.

[0068] In the shower state SC, liquid L flowing forward inside the injection tube portion 12 by operating the trigger portion 14a described above flows from inside the injection tube portion 12 into the protruding tube portion 53, and then flows into space S4 via the first communication hole 81 and the second communication groove 84, in that order. Liquid L that has flowed into space S4 flows forward and flows via the second communication hole 82 into space S5 between the fitting tube portion 23 and the intermediate tube portion 24 in the radial direction, that is, into the inside of the accommodating hole 25. Liquid L that has flowed into the inside of the accommodating hole 25 is discharged forward as liquid flows F2 from each of the multiple second discharge ports 72 provided between the discharge member 30 and the inner surface of the accommodating hole 25.

[0069] Thus, in the shower state SC, the first communication hole 81 communicates with the space S4 located inside the outer tube portion 54 and outside the fitting tube portion 23 and the intermediate tube portion 24, and with the second outlets 72 via the second communication hole 82, thereby forming a second flow path 92 that communicates the inside of the dispenser body 10 with the second outlets 72. That is, the trigger-type dispenser 3 is provided with a second flow path 92 that can communicate the inside of the dispenser body 10 with the second outlets 72. In this embodiment, the second flow path 92 is formed by the first communication hole 81, the second communication groove 84, the space S4, the second communication hole 82, and the space S5. In the second flow path 92, the liquid L flowing through the second communication groove 84 flows backward. That is, in this embodiment, the second flow path 92 has the second communication groove 84 as a flow path portion through which the liquid L flows backward.

[0070] The above-mentioned first flow path 91 is blocked in the shower state SC. Specifically, in the shower state SC, the first communication groove 83 and the third communication groove 85 are blocked, so that the liquid L that has flowed from the first communication hole 81 into the third communication groove 85 via the space S3 does not flow into the first communication groove 83. Therefore, in the shower state SC, the liquid L is prevented from reaching the first outlet 71, and the liquid L is not discharged from the first outlet 71.

[0071] The above-mentioned second flow path 92 is blocked in the direct exposure state SB. Specifically, in the direct exposure state SB, the first communication hole 81 and the second communication groove 84 are blocked, and therefore the liquid L that has flowed into the first communication hole 81 does not flow into the second communication groove 84. Therefore, in the direct exposure state SB, the liquid L is prevented from reaching the second outlets 72, and the liquid L is not discharged from the second outlets 72.

[0072] The non-ejection state SA is a state in which the liquid L cannot be ejected from either the first outlet 71 or the second outlets 72. The trigger-type ejector 3 is in the non-ejection state SA when the printed portion 21a or the printed portion 21b of the nozzle member 20 on which "STOP" is printed is located above the ejection member 30. In the non-ejection state SA, the first communication groove 83 and the third communication groove 85 are blocked, and the first communication hole 81 and the second communication groove 84 are blocked. Therefore, in the non-ejection state SA, both the first flow path 91 and the second flow path 92 are blocked. As a result, even if the trigger portion 14a is operated, the liquid L does not reach either the first outlet 71 or the second outlets 72, and the liquid L is not ejected from the first outlet 71 or the second outlets 72.

[0073] As described above, according to this embodiment, the trigger type dispenser 3 can be switched between a direct-exposure state SB in which the inside of the dispenser body 10 communicates with the first outlet 71 through the first flow path 91 and the second flow path 92 is blocked, and a shower state SC in which the inside of the dispenser body 10 communicates with the second outlets 72 through the second flow path 92 and the first flow path 91 is blocked, by rotating the nozzle member 20. Therefore, by setting the state of the trigger type dispenser 3 to the direct-exposure state SB, one liquid flow F1 can be discharged linearly from one first outlet 71, and by setting the state of the trigger type dispenser 3 to the shower state SC, the liquid L can be discharged in a shower-like manner as multiple liquid flows F2 from the multiple second outlets 72. Therefore, according to this embodiment, a trigger type dispenser 3 can be obtained that can be switched between a state in which the liquid L is discharged linearly and a state in which the liquid L is discharged in a shower-like manner.

[0074] In addition, in the shower state SC, the liquid L is discharged as multiple liquid flows F2, so the momentum of the discharged liquid L is weaker than in the direct state SB, in which one liquid flow F1 is discharged from one first outlet 71. Therefore, if the state of the trigger-type discharger 3 is the shower state SC, even if the liquid L is sprayed on a relatively nearby target, the liquid L can be prevented from scattering around. In addition, in the shower state SC, the liquid L can be sprayed over a relatively wide area by the multiple liquid flows F2. In addition, in the shower state SC, since multiple liquid flows F2 can be discharged from the multiple second outlets 72, the amount of liquid L sprayed on the target can be prevented from becoming insufficient, compared to when the liquid L becomes mist-like. As described above, according to this embodiment, a trigger-type discharger 3 is obtained that can spray a sufficient amount of liquid L over a relatively wide area while preventing the liquid L from scattering.

[0075] Furthermore, by setting the trigger-type dispenser 3 to the direct spray state SB, the force of the dispensed liquid L can be made relatively strong, making it possible to spray the liquid L even on targets that are relatively far away. Therefore, by setting the trigger-type dispenser 3 to the direct spray state SB when spraying the liquid L on a target that is relatively far away, and by setting the trigger-type dispenser 3 to the shower state SC when spraying the liquid L on a target that is relatively close, the liquid L can be suitably sprayed on targets that are relatively far away and targets that are relatively close.

[0076] Also, for example, when both the first outlet 71 and the multiple second outlets 72 are formed in the discharge member 30, the number of holes formed in the discharge member 30 to form each outlet increases, and the molding accuracy of each outlet may decrease. Specifically, burrs or the like are likely to occur in the holes formed to form each outlet, and the molding accuracy of each outlet may decrease. In contrast, according to this embodiment, the multiple second outlets 72 are provided between the discharge member 30 and the inner surface of the accommodation hole 25. Therefore, compared to the case where both the first outlet 71 and the multiple second outlets 72 are provided in the discharge member 30, the number of holes formed in the discharge member 30 can be reduced. This improves the molding accuracy of the first outlet 71 and the multiple second outlets 72. Therefore, the discharge direction of the liquid L discharged from the first outlet 71 and the multiple second outlets 72 and the momentum of the discharged liquid L can be stabilized.

[0077] Furthermore, according to this embodiment, the trigger type dispenser 3 can be switched to a non-ejection state SA in which both the first flow path 91 and the second flow path 92 are blocked by rotating the nozzle member 20. Therefore, by setting the trigger type dispenser 3 to the non-ejection state SA when not in use, it is possible to prevent the liquid L from being unintentionally dispensed when, for example, the trigger portion 14a is pulled by mistake.

[0078] Furthermore, according to this embodiment, the second flow path 92 has the second communication groove 84 as a flow path portion through which the liquid L flows backward. Therefore, in the shower state SC, the liquid L flows backward in the second communication groove 84, thereby weakening the forward momentum of the liquid L flowing in the second flow path 92. This makes it possible to further weaken the momentum of the multiple liquid flows F2 discharged from the multiple second discharge ports 72. Therefore, when the trigger-type discharger 3 is in the shower state SC and the liquid L is sprayed on a relatively nearby target, splashing of the liquid L can be further suppressed.

[0079] According to the present embodiment, in the direct exposure state SB, the first communication hole 81 communicates with the first outlet 71 through the inside of the fitting tube 23, which is located forward of the protruding tube 53, to form a first flow path 91 that communicates with the inside of the dispenser body 10 and the first outlet 71. In the shower state SC, the first communication hole 81 communicates with the space S4 located inside the outer tube 54 and outside the fitting tube 23 and the intermediate tube 24, and with the second communication hole 82 to form a second flow path 92 that communicates with the inside of the dispenser body 10 and the second outlets 72. Therefore, in each of the direct exposure state SB and the shower state SC, each flow path can be suitably configured, and it is possible to suitably switch between the direct exposure state SB in which the liquid L is discharged from the first outlet 71 and the shower state SC in which the liquid L is discharged from the second outlets 72. In addition, in this embodiment, since a plurality of second communication holes 82 are provided at intervals in the circumferential direction, the liquid L can be suitably guided to a plurality of second discharge ports 72 via the plurality of second communication holes 82.

[0080] According to this embodiment, in the direct exposure state SB, the first communication groove 83 and the third communication groove 85 communicate with each other, and the first communication hole 81 and the second communication groove 84 are blocked. In the shower state SC, the first communication groove 83 and the third communication groove 85 are blocked, and the first communication hole 81 and the second communication groove 84 communicate with each other. In this way, by providing the first communication groove 83, the second communication groove 84, and the third communication groove 85, the communication state of the first communication hole 81 and the second communication hole 82 can be easily switched by rotating the nozzle member 20. Therefore, the direct exposure state SB and the shower state SC can be switched more preferably. In addition, the second communication groove 84 makes it easy to provide a flow path portion in the second flow path 92 through which the liquid L flows backward.

[0081] According to this embodiment, as shown in FIG. 3, the printed areas 21a and 21b printed with "Stop" are arranged adjacent to each other on both sides of the printed area 21c printed with "Direct", and the printed areas 21a and 21b printed with "Stop" are arranged adjacent to each other on both sides of the printed area 21d printed with "Shower". Therefore, when the state of the trigger-type discharger 3 is switched between the direct exposure state SB and the shower state SC by rotating the nozzle member 20 around the rotation axis R, the trigger-type discharger 3 is once in the discharge-disabled state SA while switching from one of the direct exposure state SB and the shower state SC to the other. Specifically, when the state of the trigger-type discharger 3 is switched from the direct exposure state SB to the shower state SC, the trigger-type discharger 3 is switched from the direct exposure state SB to the discharge-disabled state SA once, and then to the shower state SC. Furthermore, when the state of the trigger-type discharger 3 is switched from the shower state SC to the direct exposure state SB, the trigger-type discharger 3 is switched from the shower state SC to the direct exposure state SB after once entering the discharge-dischargeable state SA.

[0082] That is, when switching the state of the trigger-type discharger 3 between the direct injection state SB in which the first communication groove 83 and the third communication groove 85 communicate with each other and the shower state SC in which the first communication hole 81 and the second communication groove 84 communicate with each other, while switching from one state to the other state, the trigger-type discharger 3 will surely enter the non-discharge state SA in which the first communication groove 83 and the third communication groove 85 are blocked and the first communication hole 81 and the second communication groove 84 are also blocked at least once. Therefore, even if a dimensional error or the like occurs in the nozzle member 20 or the like, it is possible to preferably suppress the state in which both the first communication groove 83 and the third communication groove 85 and the first communication hole 81 and the second communication groove 84 communicate with each other. Accordingly, it is possible to preferably suppress the state in which the liquid L is discharged from both the first discharge port 71 and the plurality of second discharge ports 72. Further, it is easy to preferably maintain the sealing performance between the first communication groove 83 and the third communication groove 85 and between the first communication hole 81 and the second communication groove 84.

[0083] The configuration in which the non-discharge state SA is sandwiched between the direct injection state SB and the shower state SC as described above can be realized, for example, by arranging the first communication hole 81, the first communication groove 83, the second communication groove 84, and the third communication groove 85 such that in the direct injection state SB in which the first communication groove 83 and the third communication groove 85 communicate with each other, the first communication hole 81 and the second communication groove 84 are located on the opposite sides in the radial direction with the rotation axis R interposed therebetween, and in the shower state SC in which the first communication hole 81 and the second communication groove 84 communicate with each other, the first communication groove 83 and the third communication groove 85 are located on the opposite sides in the radial direction with the rotation axis R interposed therebetween. Specifically, in the present embodiment, the first communication hole 81 and the first communication groove 83 are provided on the opposite sides in the radial direction with the rotation axis R interposed therebetween with respect to the protruding cylindrical portion 53, and the second communication groove 84 and the third communication groove 85 are provided at positions where the circumferential positions are the same with respect to the fitting cylindrical portion 23, thereby realizing the above-described configuration. For example, the above-described configuration can also be realized by providing the first communication hole 81 and the first communication groove 83 at positions where the circumferential positions are the same with respect to the protruding cylindrical portion 53, and providing the second communication groove 84 and the third communication groove 85 on the opposite sides in the radial direction with the rotation axis R interposed therebetween with respect to the fitting cylindrical portion 23.

[0084] The present invention is not limited to the above-described embodiment, and the following configurations and methods may also be adopted. The first flow path may be configured in any manner so long as it connects the inside of the dispenser body with the first outlet in the first state (direct exposure state SB) and is blocked in the second state (shower state SC). The second flow path may be configured in any manner so long as it connects the inside of the dispenser body with the second outlets in the second state (shower state SC) and is blocked in the first state (direct radiation state SB). The second flow path does not need to have a flow path portion through which the liquid flows backward.

[0085] The shape of the first outlet and the shape of the second outlet are not particularly limited. The first outlet may be provided at any position on the outlet member, as long as it is provided on the outlet member. The number of the second outlets is not particularly limited, as long as it is two or more. The second outlets do not have to surround the first outlet. The second discharge ports may be provided in any manner as long as they are provided between the discharge member and the inner surface of the accommodation hole. For example, in the above-described embodiment, the second discharge ports 72 are configured by the radially outer openings of the grooves 34 provided on the outer circumferential surface of the discharge member 30 being blocked by the inner circumferential surface of the accommodation hole 25, but this is not limited thereto. The second discharge ports may be configured by the radially inner openings of the grooves provided on the inner circumferential surface of the accommodation hole being blocked by the outer circumferential surface of the discharge member, or may be configured by aligning the grooves provided on the inner circumferential surface of the accommodation hole and the grooves provided on the outer circumferential surface of the discharge member in the radial direction.

[0086] The shape of the nozzle member as viewed from the front is not particularly limited. The nozzle member may be triangular as viewed from the front. In this case, the trigger-type discharger may be configured to be switched between a first state (direct state SB), a second state (shower state SC), and a third state (non-dischargeable state SA) when each of the three sides of the triangular nozzle member is positioned above the discharge member. In this case, for example, when the nozzle member is viewed from the front, a printed section printed with "direct", a printed section printed with "shower", and a printed section printed with "stop" may be provided one by one and arranged adjacent to each other in the circumferential direction around the rotation axis of the nozzle member. In this case, when the nozzle member is rotated around the rotation axis, the first state (direct state SB), the second state (shower state SC), and the third state (non-dischargeable state SA) are alternately switched in order.

[0087] The discharge member may have any configuration as long as it is located within the accommodation hole, attached to the nozzle member, and has a first discharge port that opens forward. The discharge member may have a polygonal or elliptical shape when viewed from the front. If the trigger-type dispenser can be switched between the first state (direct spray state SB) and the second state (shower state SC), it does not have to be switched to the third state (non-ejection state SA). The trigger-type dispenser may be switchable to a state other than the first state, the second state, and the third state. The inverted forward adapter does not necessarily have to be provided. The configurations described in this specification can be combined as appropriate within a range that does not contradict each other. [Explanation of symbols]
