However, in the conventional trigger-type liquid ejectors, the outer peripheral surface of the nozzle member is narrow, and the first and second markings must be small. This can make it difficult for elderly people and people with weak eyesight to visually distinguish the first and second markings.

The present invention was made in consideration of the above-mentioned circumstances, and aims to provide a trigger-type liquid ejector that allows easy visual identification of the first mark portion and the second mark portion.

In order to solve the above problems, the present invention proposes the following means.
The trigger type liquid ejector according to the present invention comprises an ejector body attached to a container body containing liquid, a nozzle member attached to the front end of the ejector body and having an ejection hole formed therein for ejecting liquid forward, and a cover covering the ejector body, the ejector body having a vertical supply tube section extending in the vertical direction and sucking up liquid within the container body, and a trigger section provided in front of the vertical supply tube section so as to be movable rearward in a forward biased state, and a trigger mechanism for circulating liquid from within the vertical supply tube section towards the ejection hole side by the rearward movement of the trigger section, the nozzle member having a front end portion and an ejection hole formed therein for ejecting liquid forward, The nozzle member is rotatably arranged around a nozzle axis extending in the front-to-rear direction between an ejection position that communicates with the interior of the vertical supply tube portion and a blocking position that blocks communication between the ejection hole and the interior of the vertical supply tube portion, and a magnifying glass body that covers the outer peripheral surface of the nozzle member and has a magnifying lens is connected to the cover, and the portion of the outer peripheral surface of the nozzle member that is covered by the magnifying lens is provided with at least one of a first mark portion indicating that the nozzle member is located at the ejection position relative to the ejector body and a second mark portion indicating that the nozzle member is located at the blocking position relative to the ejector body.

According to the present invention, a magnifying glass body having a magnifying lens is connected to the cover, and at least one of a first mark portion and a second mark portion is provided on the outer peripheral surface of the nozzle member in a portion covered by the magnifying lens, so that it is possible to at least one of enlarging and visually confirming the first mark portion when the nozzle member is in the ejection position, and enlarging and visually confirming the second mark portion when the nozzle member is in the blocking position. This makes it easy to distinguish between the first mark portion and the second mark portion by visual confirmation.
Therefore, even elderly people and people with weak eyesight can reliably distinguish the small first mark portion or the small second mark portion.

The first mark portion and the second mark portion may be provided at different positions in the nozzle circumferential direction around the nozzle axis on the outer peripheral surface of the nozzle member, and the magnifying lens may cover the first mark portion when the nozzle member is located at the ejection position, and cover the second mark portion when the nozzle member is located at the blocking position.

In this case, the magnifying lens covers the first mark portion when the nozzle member is in the ejection position, and covers the second mark portion when the nozzle member is in the blocking position. This makes it possible to magnify and view the first mark portion when the nozzle member is in the ejection position, and the second mark portion when the nozzle member is in the blocking position, and therefore makes it easy to distinguish and view the first and second mark portions.

The outer peripheral surface of the nozzle member, when viewed from the front-to-rear direction, has an angular shape with sides and corners alternately arranged in the nozzle circumferential direction, the first mark portion and the second mark portion are provided separately on different sides, and the magnifying glass body may be provided so as to be movable forward and backward relative to the outer peripheral surface of the nozzle member.

In this case, the first mark portion and the second mark portion are provided separately on different edge portions, and the loupe body is provided so as to be able to move forward and backward relative to the outer peripheral surface of the nozzle member. Therefore, when an attempt is made to rotate the nozzle member in the nozzle circumferential direction with the loupe body covering one of the edge portions of the outer peripheral surface of the nozzle member, the end portion of the loupe body in the nozzle circumferential direction will get caught on the connection portion between the edge portion and the corner portion on the outer peripheral surface of the nozzle member.
Therefore, when the magnifying glass body covers one edge portion of the outer peripheral surface of the nozzle member, it becomes difficult to rotate the nozzle member in the nozzle circumferential direction, and after confirming the distinction between the first and second mark portions through the magnifying lens with the rotational movement of the nozzle member suppressed, the magnifying glass body can be moved back from the outer peripheral surface of the nozzle member to rotate the nozzle member, thereby preventing a deterioration in operability and improving safety.

The magnifying glass body may be removably attached to the nozzle member and may have a restricting portion that restricts the rotational movement of the nozzle member about the nozzle axis.

In this case, the loupe body is removably attached to the nozzle member and has a regulating part that regulates the rotational movement of the nozzle member about the nozzle axis, so that it is possible to prevent the nozzle member, which is positioned in the blocking position, from being mistakenly moved to the spraying position by, for example, a child, thereby improving safety.
By attaching the regulating portion to the nozzle member and restricting the rotational movement of the nozzle member, it is possible to confirm the distinction between the first mark portion and the second mark portion using a magnifying lens, and then remove the regulating portion from the nozzle member and rotate the nozzle member, thereby preventing a deterioration in operability and improving safety.

According to the present invention, the first mark portion and the second mark portion can be easily distinguished by visual inspection.

FIG. 2 is a vertical cross-sectional view of a trigger-type liquid ejector according to one embodiment. FIG. 2 is a front view of the nozzle member of FIG. 1 . FIG. 2 is a top view of FIG. 1 .

An embodiment of a trigger type liquid ejector will be described below. As shown in Fig. 1, the trigger type liquid ejector 1 includes an ejector body 11 that is attached to a container body A that contains liquid, a nozzle member 12 that is attached to the ejector body 11, and a cover 30 that covers the ejector body 11.
Unless otherwise specified, each component part of the trigger type liquid ejector 1 is a molded product made of synthetic resin.

The ejector body 11 has a vertical supply tube portion 13 and a trigger mechanism T.
Hereinafter, the direction along the central axis O1 of the vertical supply tube portion 13 is referred to as the vertical direction, and the bottom side (not shown) of the container body A along the vertical direction is referred to as the lower side, and the opposite side is referred to as the upper side. When viewed from the vertical direction, the side where the nozzle member 12 is located with respect to the vertical supply tube portion 13 is referred to as the front side, and the opposite side is referred to as the rear side. When viewed from the vertical direction, the direction perpendicular to the front-rear direction is referred to as the left-right direction.

The vertical supply tube portion 13 is inserted into the mouth portion A1 and sucks up the liquid in the container body A.
The trigger mechanism T causes the liquid to flow from inside the vertical supply tube portion 13 toward the nozzle hole 15 side described later by the rearward movement of the trigger portion 14. The trigger mechanism T includes a trigger portion 14 extending in the vertical direction and provided in front of the vertical supply tube portion 13 so as to be movable rearward in a forward biased state, a piston 16 that moves back and forth in conjunction with the movement of the trigger portion 14, and a cylinder 17 into which the piston 16 is inserted and whose inside communicates with the inside of the vertical supply tube portion 13.

An injection tube portion 20 is provided in front of the vertical supply tube portion 13 .
The injection tube portion 20 allows the liquid in the vertical supply tube portion 13 to flow toward the injection hole 15 side described later. The injection tube portion 20 extends forward from the upper end portion of the vertical supply tube portion 13. The inside of the injection tube portion 20 is connected to the inside of the vertical supply tube portion 13.

A valve mechanism 27 is provided within the vertical supply tube portion 13 .
When the internal pressure of the cylinder 17 rises due to the rearward movement of the trigger portion 14, the valve mechanism 27 connects the inside of the cylinder 17 to the inside of the injection tube portion 20 while blocking communication between them, and when the pressure inside the cylinder 17 becomes negative due to the forward return movement of the trigger portion 14, the valve mechanism 27 connects the inside of the cylinder 17 to the inside of the injection tube portion 20 while blocking communication between them.

A relay member 18 is assembled to the injection tube portion 20 from the front.
The relay member 18 comprises a partition 19 covering the front end opening of the injection tube portion 20 from the front, an outer fitting tube portion 21 extending rearward from the partition 19 and fitted onto the injection tube portion 20, a first mounting tube portion 22 extending forward from the partition 19 and having the nozzle member 12 attached thereto, and a guide shaft portion 23 extending forward from a portion of the partition 19 located inside the first mounting tube portion 22.

A communication hole 24 that communicates with the inside of the injection cylinder portion 20 is formed in the partition wall 19 at a portion located inside the first mounting cylinder portion 22 .
A first switching groove 28 extending in the front-rear direction and opening forward is formed on the outer circumferential surface of the front end of the guide shaft portion 23. The guide shaft portion 23 and the first mounting tube portion 22 are arranged coaxially with a common axis extending in the front-rear direction.
Hereinafter, this common axis will be referred to as the nozzle axis O2, the direction intersecting the nozzle axis O2 when viewed from the front-to-rear direction will be referred to as the nozzle radial direction, and the direction circumferential around the nozzle axis O2 will be referred to as the nozzle circumferential direction.

An inverted normal adapter 50 is attached to the vertical supply tube portion 13 .
The inverted forward adapter 50 is configured so that when the container body A to which the ejector main body 11 is attached is in the upright position, as well as when the container body A is inverted, the liquid in the container body A can be supplied into the cylinder 17 through the vertical supply tube portion 13 when negative pressure is generated in the cylinder 17 due to the return movement of the trigger portion 14 toward the front.
It should be noted that the inverted normal adapter 50 need not be provided.

The nozzle member 12 is attached to the front end of the ejector body 11, and has an ejection hole 15 that ejects liquid forward. The nozzle member 12 is attached to the relay member 18 so as to be rotatable about the nozzle axis O2. The nozzle member 12 is attached to the first attachment tube portion 22.
The nozzle member 12 includes a second mounting tubular portion 25 rotatably fitted onto the first mounting tubular portion 22, and a fitting tubular portion 26 provided inside the second mounting tubular portion 25 and rotatably fitted onto the guide shaft portion 23. The second mounting tubular portion 25 and the fitting tubular portion 26 are disposed coaxially with the nozzle axis O2.

A second switching groove 29 is formed on the inner peripheral surface of the fitting tube portion 26, extending in the front-rear direction and opening to the rear. The second switching groove 29 is connected to the inside of the first mounting tube portion 22. The second switching groove 29 is disposed in correspondence with the first switching groove 28 of the guide shaft portion 23. The front end portion of the second switching groove 29 and the rear end portion of the first switching groove 28 are positioned in the same front-rear direction.

As the nozzle member 12 rotates around the nozzle axis O2, when the circumferential positions of the first switching groove 28 and the second switching groove 29 coincide with each other, the ejection hole 15 communicates with the inside of the vertical supply tube portion 13 through the inside of the first mounting tube portion 22, the communication hole 24, and the inside of the injection tube portion 20, and when the second switching groove 29 moves circumferentially away from the first switching groove 28, the communication between the ejection hole 15 and the inside of the vertical supply tube portion 13 is cut off.
That is, the nozzle member 12 is rotatable around the nozzle axis O2 between an ejection position that connects the ejection hole 15 to the inside of the vertical supply tube portion 13 and a blocking position that blocks communication between the ejection hole 15 and the inside of the vertical supply tube portion 13.

The nozzle member 12 includes a closing wall 12a that integrally closes the front end openings of the second mounting tubular portion 25 and the fitting tubular portion 26, and a nozzle tube 31 that surrounds the second mounting tubular portion 25 from the outside in the nozzle radial direction.
The blocking wall 12a is formed with an ejection hole 15 that opens forward. The ejection hole 15 has a rear end opening that opens into the fitting cylinder portion 26.
The front portion of the nozzle cylinder 31 protrudes forward from the blocking wall 12a. The front end opening of the ejection hole 15 opens into the nozzle cylinder 31.

At least one of a first mark X (see FIG. 3) indicating that the nozzle member 12 is in the ejection position relative to the ejector body 11 and a second mark indicating that the nozzle member 12 is in the blocking position relative to the ejector body 11 is provided on the outer peripheral surface of the nozzle tube 31 (the outer peripheral surface of the nozzle member 12), which is covered by the magnifying lens 41 described below.

In the illustrated example, the first mark portion X and the second mark portion are provided on the outer circumferential surface of the nozzle cylinder 31 at different positions in the nozzle circumferential direction.
In the process of rotating the nozzle member 12 around the nozzle axis O2, when the first mark portion X faces upward, it indicates that the nozzle member 12 is in the ejection position, and when the second mark portion faces upward, it indicates that the nozzle member 12 is in the blocking position. Note that the directions in which the first mark portion X and the second mark portion face may be changed as appropriate.

A plurality of bulging portions 31a, which bulge outward in the nozzle radial direction, are formed at intervals in the nozzle circumferential direction on the outer circumferential surface of the rear end portion of the nozzle cylinder 31. The first mark portion X and the second mark portion are provided separately on different bulging portions 31a.
2, the outer circumferential surface of the nozzle cylinder 31, when viewed from the front-rear direction, has an angular shape in which side portions 32 and corner portions 33 are alternately arranged in the nozzle circumferential direction, and the first mark portion X and the second mark portion are provided separately on different side portions 32. The multiple bulging portions 31a are also provided separately on different side portions 32.

The cover 30 covers a part of the trigger mechanism T and a part of the trigger portion 14. The part that the cover 30 covers of the ejector body 11 can be changed as appropriate, and for example, the cover 30 may cover the entire piston 16 and the cylinder 17.
The cover 30 includes a pair of left and right side walls 35 and an upper wall 36. The side walls 35 and the upper wall 36 are integrally formed.

The side walls 35 are formed in plate shapes extending in the front-rear and up-down directions, and are arranged at intervals in the left-right direction. The side walls 35 cover both the left-right sides of the ejector body 11. The vertical dimension of the side walls 35 becomes smaller toward the front.
The upper wall 36 is formed in a plate shape extending in the front-rear and left-right directions, and connects the upper ends of the pair of side walls 35. The upper wall 36 covers the ejector body 11 from above.

In this embodiment, a magnifying glass body 42 that covers the outer peripheral surface of the nozzle cylinder 31 and has a magnifying lens 41 is connected to the cover 30 .
The magnifying lens 41 covers the first mark portion X when the nozzle member 12 is located at the ejection position, and covers the second mark portion when the nozzle member 12 is located at the blocking position. At least the magnifying lens 41 of the magnifying glass body 42 is made of a transparent synthetic resin material. The magnifying lens 41 magnifies and makes visible the covered characters, figures, symbols, etc. The magnifying lens 41 is formed in a bulging hemispherical shape and is provided at the rear end of the magnifying glass body 42.

The magnifying glass body 42 is provided so as to be movable forward and backward with respect to the outer circumferential surface of the nozzle cylinder 31. The magnifying glass body 42 may be fixed to the cover 30.
In the illustrated example, the rear end of the loupe body 42 and the front end of the upper wall 36 of the cover 30 are connected via a hinge portion 43. The loupe body 42 is provided so as to be rotatable in the vertical direction around the hinge portion 43. The loupe body 42 is formed integrally with the cover 30. The loupe body 42 is provided so as to be movable forward and backward in the vertical direction relative to the outer circumferential surface of the nozzle cylinder 31.

The loupe body 42 may be separate from the cover 30. The loupe body 42 may be provided so as to be movable forward and backward or left and right relative to the outer peripheral surface of the nozzle tube 31.

The loupe body 42 is formed in a plate shape with the front and back surfaces facing the up-down direction. The loupe body 42 has a rectangular shape when viewed from the up-down direction. A pair of sides that define this rectangular shape extend in the front-rear direction, and the remaining pair of sides extend in the left-right direction. The back surface of the loupe body 42 abuts against or is close to the outer peripheral surface of the nozzle tube 31. As shown in FIG. 3, the circumferential sizes of the loupe body 42 and one of the side portions 32 of the outer peripheral surface of the nozzle tube 31 are equal to each other. A recessed portion 42a is formed on the back surface of the loupe body 42, into which the bulging portion 31a of the nozzle member 12 is detachably fitted. The recessed portion 42a and the magnifying lens 41 face each other in the plate thickness direction of the loupe body 42.

The loupe body 42 has a restricting portion 44. The restricting portion 44 is detachably attached to the nozzle member 12, and restricts the rotational movement of the nozzle member 12 about the nozzle axis O2.
The restricting portion 44 is formed at the front end of the loupe body 42. The restricting portion 44 protrudes downward from the front end of the loupe body 42, and is releasably engaged with the upper end of the front end opening edge of the nozzle cylinder 31. A locking protrusion is formed on the rear surface of the restricting portion 44 facing rearward, and the locking protrusion is detachably engaged with the front end opening edge of the nozzle cylinder 31 via an undercut.

Next, the operation of the trigger type liquid ejector 1 configured as above will be described.
It is assumed that liquid is filled into each part of the ejector body 11 by operating the trigger portion 14 multiple times.

First, the outer peripheral surface of the nozzle tube 31 is visually inspected through the magnifying lens 41 to check whether the nozzle member 12 is in the ejection position or the blocking position by checking whether the first mark portion X and the second mark portion are located.
When the second mark portion is visually confirmed through the magnifying lens 41 and it is confirmed that the nozzle member 12 is in the blocking position, the magnifying glass body 42 is rotated upward about the hinge portion 43 to move backward from the nozzle cylinder 31, and the restricting portion 44 is detached from the nozzle member 12. Then, after the nozzle member 12 is rotated a predetermined amount about the nozzle axis O2, the magnifying glass body 42 is rotated downward about the hinge portion 43 to abut or approach the outer circumferential surface of the nozzle cylinder 31, and the restricting portion 44 is engaged with the front end opening edge of the nozzle member 12. In this state, the outer circumferential surface of the nozzle cylinder 31 is visually observed again through the magnifying lens 41.
3, when the first mark portion X is visually recognized, it is confirmed that the nozzle member 12 is located at the ejection position. At this time, the ejection hole 15 and the inside of the vertical supply tube portion 13 are in communication with each other through the first switching groove 28, the second switching groove 29, the inside of the first mounting tube portion 22, the communication hole 24, and the inside of the ejection tube portion 20.

Next, when the trigger portion 14 is pulled backward against the forward biasing force, the piston 16 retracts as the trigger portion 14 moves backward, and the liquid in the cylinder 17 is introduced into the vertical supply tube portion 13. The liquid introduced into the vertical supply tube portion 13 is not supplied into the container body A while operating the valve mechanism 27, but is supplied into the injection tube portion 20, and then reaches the ejection hole 15 through the communication hole 24, the first mounting tube portion 22, the second switching groove 29, and the first switching groove 28, and is ejected from the ejection hole 15.

When the trigger 14 is released after the liquid is ejected, the trigger 14 moves forward to return to its original position, which in turn moves the piston 16 forward. This generates negative pressure in the cylinder 17, which activates the valve mechanism 27, and the liquid in the container body A is sucked up into the vertical supply tube 13, and then introduced into the cylinder 17 without being introduced into the injection tube 20.
Thereafter, in the same manner as described above, the loupe body 42 is rotated about the hinge portion 43, the nozzle member 12 is rotated about the nozzle axis O2, and the first mark portion X and the second mark portion are separately viewed through the magnifying lens 41, thereby engaging the regulating portion 44 with the front end opening edge of the nozzle member 12 positioned in the blocking position.

As described above, according to the trigger-type liquid ejector 1 of this embodiment, the magnifying glass body 42 having the magnifying lens 41 is connected to the cover 30, and at least one of the first mark portion X and the second mark portion is provided on the portion of the outer circumferential surface of the nozzle member 12 that is covered by the magnifying lens 41, so that it is possible to at least one of enlarging and visually confirming the first mark portion X when the nozzle member 12 is located at the ejection position, and enlarging and visually confirming the second mark portion when the nozzle member 12 is located at the blocking position. This makes it possible to easily distinguish between the first mark portion X and the second mark portion by visual confirmation.
Therefore, even elderly people and people with weak eyesight can reliably distinguish the small first mark portion X or the small second mark portion.

The magnifying lens 41 covers the first mark portion X when the nozzle member 12 is in the ejection position, and covers the second mark portion when the nozzle member 12 is in the blocking position. This makes it possible to magnify and view the first mark portion X when the nozzle member 12 is in the ejection position, and the second mark portion when the nozzle member 12 is in the blocking position, and therefore makes it easy to distinguish and view the first mark portion X and the second mark portion.

The first mark X and the second mark are provided separately on different side portions 32, and the loupe body 42 is provided so as to be movable forward and backward with respect to the outer peripheral surface of the nozzle member 12. Therefore, when an attempt is made to rotate the nozzle member 12 in the nozzle circumferential direction with the loupe body 42 covering one of the side portions 32 of the outer peripheral surface of the nozzle member 12, the end portion of the loupe body 42 in the nozzle circumferential direction gets caught on the connection portion between the side portion 32 and the corner portion 33 on the outer peripheral surface of the nozzle member 12.

Therefore, when the magnifying glass body 42 covers one edge portion 32 of the outer peripheral surface of the nozzle member 12, it becomes possible to make it difficult to rotate the nozzle member 12 in the nozzle circumferential direction, and after confirming the distinction between the first mark portion X and the second mark portion through the magnifying lens 41 while the rotational movement of the nozzle member 12 is suppressed, the magnifying glass body 42 can be moved back from the outer peripheral surface of the nozzle member 12 to rotate the nozzle member 12, thereby preventing a deterioration in operability and improving safety.

Since the loupe body 42 is removably attached to the nozzle member 12 and has a regulating portion 44 that regulates the rotational movement of the nozzle member 12 about the nozzle axis O2, it is possible to prevent the nozzle member 12, which is located in the blocking position, from being mistakenly moved to the spraying position by, for example, a child, thereby improving safety.
With the regulating portion 44 attached to the nozzle member 12 and the rotational movement of the nozzle member 12 restricted, the distinction between the first mark portion X and the second mark portion can be confirmed using the magnifying lens 41, and then the regulating portion 44 can be removed from the nozzle member 12 to allow the nozzle member 12 to be rotationally moved, thereby preventing a deterioration in operability and improving safety.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, the outer circumferential surface of the nozzle cylinder 31 may have a circular shape when viewed from the front-rear direction.
The loupe body 42 may be connected to the side wall 35 of the cover 30 or the like.
Only one of the first mark portion X and the second mark portion may be provided on the outer circumferential surface of the nozzle member 12 .

In addition, the components in the above-described embodiments may be replaced with well-known components as appropriate without departing from the spirit of the present invention, and the above-described embodiments and variations may be combined as appropriate.
