  The ejector main body 2 includes a mounting member 4, a flow path forming member 8, a trigger 20 that is an operating portion, and a cover member 28.

  The mounting member 4 has a mounting cylinder portion 4a that opens a mounting port 6 for mounting to the container body 100 on the lower surface, and the mounting cylinder portion 4a is fitted to the outer circumference of the mouth / neck portion 102 of the container body 100. Is provided so that it can be attached to the container body.

The flow path forming member 8 is a member for forming a liquid flow path P1 that guides the liquid sucked from the container body side to a nozzle member 30 described later.
The flow path forming member 8 of the illustrated example has a fitting base portion 9 which is inserted into the mounting cylinder portion 4a and can be fitted in a liquid-tight manner to the mouth / neck portion 102 of the container body 100. From this fitting base portion 9 The vertical main cylinder 10 is erected, the injection cylinder 12 projects forward from the upper part of the vertical main cylinder 10, and the cylinder 18 projects downward from the vertical main cylinder 10 below the injection cylinder 12. A piston 19 shown in FIG. 3 is housed in the cylinder 18 so as to be movable back and forth to form a pump chamber A. A coil spring is interposed between the cylinder 18 and the piston 19.
In this specification, “front” means the right side of FIG. 1, “rear” means the left side of FIG. 1, and the direction perpendicular to the plane of the drawing is the left-right direction.
A suction pipe 11 is hung from the fitting base 9.
The front end portion of the injection cylinder 12 is formed as a diameter-expanded cylinder portion 12a.
A valve member 16 is inserted in the injection cylinder 12. The valve member 16 of the present embodiment includes a corrugated plate portion 16a and a laterally columnar valve portion 16b. These structures can be changed appropriately.
By fixing the rear end portion of the corrugated plate portion 16a (not shown) at a proper position in the injection cylinder 12 and bringing the valve portion 16b into contact with an inner nozzle 32, which will be described later, in the liquid passage P1 downstream of the pump chamber A. A downstream check valve V located at is formed.
An upstream check valve (not shown) is formed on the upstream side of the pump chamber A in the liquid flow path P1.

  The trigger 20 has an upper end portion rotatably connected to both front portions of the injection cylinder 12 and is hung so as to be swingable in the front-rear direction. The trigger 20 is linked to the piston 19, and is formed such that when the trigger 20 is pulled rearward, the piston 19 can be retracted against the forward biasing force of the coil spring. The trigger 20 of the illustrated example is formed by connecting the longitudinal strip-shaped front plate portion 22 shown in FIG. 3 to the front ends of a pair of side plate portions 24 whose upper ends are pivotally attached to the bodies on both sides of the injection cylinder 12. However, the structure can be changed appropriately.

  The cover member 28 covers the upper side, the rear side, and the left and right sides of the flow path forming member 8.

  The nozzle member 30 is attached to the front end of the injection cylinder 12. A rotary lever 40 is projected from the nozzle member 30, and an opening / closing mechanism D for opening / closing a flow path in the nozzle member by rotating the lever is provided. For convenience of description, a detailed description of the nozzle member 30 and the opening / closing mechanism D will be described later.

In order to use the dispenser 1, the dispenser 1 is attached to the mouth / neck portion 102 of the container body 100 shown by an imaginary line in FIG.
In the state where the rotary lever is in the closed position shown in FIG. 3, the opening / closing mechanism D closes the flow path in the nozzle member 30, and the liquid cannot be ejected even if the trigger 20 is pulled.
When the rotary lever 40 is moved to the open position shown in FIG. 5 and the trigger 20 is pulled, the piston 19 retracts in the cylinder 18, and the liquid in the pump chamber A passes through the downstream check valve V, the injection cylinder 12, and the nozzle. It is discharged outward from the member 30. When the trigger 20 is released, the elastic restoring force of the coil spring causes the piston 19 to advance, and the liquid in the container body 100 is sucked into the pump chamber A via the upstream check valve.

  In the present invention, the nozzle member 30 includes an inner nozzle 32 and an outer nozzle 42, as shown in FIG.

As shown in FIG. 2, the inner nozzle 32 has a vertical substrate 33 having a through hole 34 in the center in the illustrated example. From the rear surface of the vertical substrate 33, a small diameter cylindrical portion 36a and a medium diameter cylindrical portion 36b are formed. The large-diameter tubular portion 36c and the three-dimensional tubular portion are projected rearward.
The front portion of the expanded diameter cylinder portion 12a of the injection cylinder 12 is liquid-tightly sandwiched between the large diameter cylinder portion 36c and the medium diameter cylinder portion 36b.
The valve portion 16b of the valve member 16 is inserted into the small-diameter tubular portion 36a, and is pressed against the rear surface of the vertical substrate 33 in the small-diameter tubular portion 36a to form a downstream check valve V.
On the outer peripheral surface of the valve portion 16b and the inner peripheral surface of the small diameter cylindrical portion 36a, there are formed groove portions which can be continuous and separated from each other by the rotation of the inner nozzle 32 with respect to the injection cylinder 12, respectively. The above-mentioned opening / closing mechanism D is thus formed.
A conventionally known spin groove G is formed between these groove portions and the through hole 34.

  The rotary lever 40 is projected from a proper position (one side surface in the left-right direction in the illustrated example) of the inner nozzle 32. The illustrated rotation lever 40 is formed of a horizontal plate portion 40a that projects laterally from the inner nozzle 32, and a vertical plate portion 40b that hangs downward from the horizontal plate portion 40a along the trigger 20. From the lower portion of the vertical plate portion 40b, a locking plate portion s that restricts the rotation range of the rotary lever by abutting on the side surface of the trigger is provided so as to project rearward. Further, the vertical plate portion 40b is provided with a cover plate c for covering the front surface of the trigger 20 and a knob k projecting forward from the cover plate.

  An annular groove 38 surrounding the through hole 34 is formed on the front surface of the vertical substrate 33. The illustrated annular groove 38 is formed between the inner tubular portion 38 a and the outer tubular portion 38 b that project forward from the vertical substrate 33.

The outer nozzle 42 has a horizontal cylindrical base cylinder portion 44 fitted outside the large-diameter cylinder portion 36c of the inner nozzle 32. The base nozzle portion 44 projects forward from the base cylinder portion 44 and bends upward. A nozzle tube 52 having a character shape is provided.
An outer peripheral wall 48 projects rearward from the front end of the base tubular portion 44 via a first connecting wall portion 46. In the illustrated example, as shown by the broken line in FIG. 7, the upper wall portion of the outer peripheral wall 48 is flat and continuous with the upper wall portion of the base cylinder portion 44. However, the structure can be changed appropriately.
As shown in FIG. 9, a pair of left and right locking arms 50 are projected rearward from both left and right sides of the lower wall portion of the outer peripheral wall 48. These locking arms 50 extend along the left and right sides of the body portion near the injection cylinder, or extend rearward from the position of the trigger, and are locked on both sides of the body. These both locking arms 50 function as a rotation stopping means T for suppressing the outer nozzle 42 with respect to the dispenser body 2 side.
The locking arm is not limited to the body portion, and may be locked on both left and right sides of the trigger, and may be locked anywhere on the main body of the dispenser as long as it can perform the locking function.
Both locking arms 50 may abut on both left and right side surfaces of the trigger 20, but they may be brought close to each other with some play for facilitating the operation of the trigger 20.
In the illustrated example, each locking arm 50 is formed of a locking plate portion 50a having a vertically long cross section and a stiffening rib 50b attached to the lower end of the locking plate portion 50a, as shown in FIG. However, this shape can be changed appropriately.
Further, in a preferred illustrated example, the projecting length of the base tube portion 44 is designed so as not to reach the projecting position of the rotary lever 40 from the inner nozzle 32, as shown in FIG. The outer peripheral wall 48 is provided longer than the base cylinder portion 44, and a part of the rear end portion of the cylinder wall in the circumferential direction is cut out to form an insertion port 49 for inserting the rotary lever 40 (FIG. 6).

The nozzle tube 52 is provided with a partition wall 54 that divides the interior of the nozzle tube into two portions extending in the direction in which the fluid passes along the curve of the tube wall, and one of the two portions is provided with a discharge flow path P2, The other is used as the outside air introduction path P3.
In the illustrated example, the outside air introduction path P3 is provided inside the bent portion of the tube wall, and the discharge flow path P2 is provided outside the bent portion. With this configuration, in the use state shown in FIG. 10, the outer side end of the outside air introduction path P3 can be located above the outer side end of the discharge flow path P2, and the positional relationship is reversed. The outside air can be introduced more accurately than the above.
Further, it is desirable that the cross-sectional area of the content discharge flow path P2 be larger than the cross-sectional area of the outside air introduction path P3 as shown in FIG.

In this embodiment, as shown in FIG. 9, the partition wall 54 includes a first partition wall portion 54a parallel to the tube axis direction (front-back direction) of the base portion 52a of the nozzle tube 52 and a tube axis of the tip portion 52b of the nozzle tube 52. The second partition 54b is parallel to the direction (vertical direction). With this configuration, it is easy to remove the die when molding the outer nozzle 42.
In the illustrated example, the second partition wall portion 54b is a vertical wall portion extending from below the bent portion of the nozzle tube to near the upper end of the tip portion 52b, and the first partition wall portion 54a is continuous at the front end with the second partition wall portion 54b. Cylindrical,
The first orifice 56 is opened in the second partition wall portion 54b inside the first partition wall portion 54a. However, this configuration can be changed appropriately. The rear end portion of the cylindrical first partition wall portion 54a is fitted in the annular groove 38 so as to be slidable in the circumferential direction, thereby enabling the rotation of the inner nozzle with respect to the injection cylinder and the outer nozzle. I am trying. A first communication hole 58 that communicates the discharge flow path P2 and the outside air introduction path P3 is opened at the rear portion of the first partition wall 54a.
In this embodiment, the liquid is ejected from the through hole 34 by the trigger operation, and is mixed with the outside air sucked through the outside air introduction path P3, so that the mixture of the liquid and the air collides with the inner surface of the discharge flow path P2. As a result, the bubbles are ejected from the upper end of the discharge flow path P2 through the first orifice 56.

  A cap 70 may be attached to the upper end of the outer nozzle 42. The cap 70 is formed by connecting a cap cylinder 72 and a lid 74 with a hinge 76.

Further, in this embodiment, the locking member 14 for stopping the operation of the trigger is assembled by utilizing the gap between the pair of locking arms 50. The locking member in the illustrated example is a vertically elongated rectangular ring body that surrounds the injection cylinder 12, and there is play (a lifting allowance) between the hole of this ring body (called a ring hole) and the outer surface of the injection cylinder 12. The corresponding portion of the locking member 14 and trigger 20 has uneven engagement means, the trigger is locked in a state in which the engaging member 14 is lowered against the injection cylinder 12 as shown in FIG. 3, FIG. As shown in FIG. 5, the lock is provided so that the lock is released when the locking member 14 is raised. In the illustrated example, an engaging groove 21 is formed on the front surface of the trigger 20 as shown in FIG. 5, and the engaging rib 15 provided on the rear surface of the engaging member 14 is separably fitted into the engaging groove 21. By wearing it, a braking means for braking the movement of the trigger 20 is formed.

In the above structure, when the rotary lever 40 is grasped and rotated from the closed position shown in FIG. 3 to the open position shown in FIG. 5, the inner nozzle 32 rotates with respect to the injection cylinder 12, but at this time, the outer nozzle 42 causes the ejector to move. Since it is locked to the 1 side, it does not rotate. As a result, it is possible to prevent the outer nozzle 42 from rotating downward and causing liquid leakage against the wishes of the consumer. The opening / closing mechanism D opens the passage in the nozzle member 30 by the rotation of the inner nozzle 32, and the liquid can be discharged by operating the trigger 20.
In this state, for example, as shown in FIG. 10, the container with the dispenser is turned sideways, the tip portion 52b of the nozzle tube 52 is directed toward the inner edge of the toilet bowl of the toilet, and the trigger 20 is pulled. The contents can be effectively and effectively sprayed on the.
When the use is finished, the opening / closing mechanism D closes the flow path in the nozzle member 30 by rotating the rotary lever 40 from the open position to the closed position, and returns to the state of FIG.

  Hereinafter, another embodiment of the present invention will be described. In these descriptions, description of the same configurations as those of the first embodiment will be omitted.

11 to 12 show a dispenser 1 according to a second embodiment of the present invention.
In the present embodiment, the inner nozzle 32 has a single joint cylinder portion 39 that projects forward from the front surface of the vertical substrate 33, omitting the annular groove 38. A through hole 34 is opened at an eccentric position of the vertical substrate 33 portion of the joint tubular portion.
In the illustrated example, the outer nozzle 42 has a dog-legged nozzle tube 52 having a base portion 52a in the front-rear direction and a tip portion 52b extending obliquely upward, and the base portion 52a is fitted into the joint tubular portion 39. There is. An inclined orifice plate 45 having a second orifice 45a is formed between the base portion 52a and the tip portion 52b of the nozzle tube 52.
An outer peripheral wall 48 projects rearward from the tip end side of the nozzle tube 52 via a second connecting wall portion 47. In the present embodiment, an appropriate number (two in the illustrated example) of second communication holes 59 are opened in the cylindrical wall forming the tip portion 52b. Therefore, the outside air can be efficiently introduced into the flow path with a simple configuration.
As shown in FIG. 12, a horizontally oriented rod-shaped body 80 is fitted in the base portion 52a of the nozzle tube 52. The front end surface 82 of the rod-shaped body 80 is an inclined surface that is in close contact with the orifice plate 45, and when the inner nozzle 32 is rotated, the rod-shaped body 80 is formed to be stationary together with the outer nozzle 42. . A plurality of (three in the present embodiment) channel-shaped passages 84 communicating with the through holes 34 are formed in the front-rear direction from the outer peripheral surface of the rod-shaped body 80 to the outer peripheral portion of the rear surface. Then, a spin groove G which is continuous with the channel-shaped passage and reaches the second orifice 45 a is formed between the front portion of the rod-shaped body 80 and the orifice plate 45.
In the present embodiment, the liquid discharged from the second orifice 45a mixes with the outside air sucked from the second communication hole 59, and collides with the inner surface of the tip portion 52b to be foamed, so that the bubble is ejected to the outside. Is configured. However, the liquid ejected from the ejection holes 34 may be ejected as mist in a state where it does not collide with the inner surface of the tip portion.
