Description

The present invention relates to a trigger-type liquid ejector.

A trigger-type liquid ejector is disclosed that includes an ejector body having a pump section, a nozzle member having an ejection hole for ejecting liquid, a trigger section that operates the pump section as it moves back and forth, and a cover that covers the ejector body while exposing the ejection hole (see, for example, Patent Document 1 below).

To perform the ejection operation with this type of trigger-type liquid ejector, for example, the index finger (or middle finger) is hooked on the trigger portion and the hand is placed around the portion of the ejector body that is located below the cover (for example, the attachment cap, etc.). In this state, when the trigger portion is pulled backward, the pump portion operates as the trigger portion moves backward, and liquid is ejected through the ejection hole. In particular, when ejecting, the underside of the rear end portion of the cover (hereinafter referred to as the support portion) is supported by the back of the hand (the portion located between the thumb and index finger), so that the trigger-type liquid ejector can be held stably even when the contents are contained in the container body and the weight is heavy.

JP 2020-82042 A

In order to further improve the operability of a trigger-type liquid sprayer, it is possible to secure a large surface area for the support part. However, if the surface area of the support part is increased, the amount of rearward protrusion of the cover from the sprayer body increases, which may lead to an increase in the size of the trigger-type liquid sprayer. As a result, there is a possibility that the space efficiency will decrease during the distribution stage (when displayed in stores, etc.) and when not in use. Furthermore, an increase in the size of the cover may increase the amount of resin required to mold the cover.

The present invention provides a trigger-type liquid ejector that is small and space-efficient while maintaining ease of use.

In order to solve the above problems, the present invention employs the following aspects.
A trigger-type liquid ejector according to one embodiment of the present invention comprises a ejector body having a pump section that ejects liquid contained in a container body, a nozzle member attached to the front end of the ejector body and having an ejection hole formed therein that ejects liquid ejected by the pump section forward, a trigger section arranged to be movable rearward in a forward biased state and that drives the pump section, a cover body that covers the ejector body, and a cover having a support section connected to the rear end of the cover body via a hinge section, wherein the support section is configured to be rotatable around the hinge section relative to the cover body between a first position in which it extends rearward from the cover body, and a second position in which the amount of rearward protrusion from the cover body is less than the first position.

According to this aspect, by moving the support part to the protruding position during the ejection operation, the trigger-type liquid ejector can be supported on the back of the hand via the support part, allowing the user to stably hold the trigger-type liquid ejector and improving operability.
On the other hand, by moving the support part to the storage position during distribution or when not in use, the amount of rearward protrusion of the cover from the ejector body can be reduced. This makes it possible to provide a small trigger-type liquid ejector that is space-efficient. In addition, by making the cover smaller, the amount of resin required to mold the cover can be reduced, leading to cost reductions.

In the trigger-type liquid ejector of the above aspect, it is preferable that the support portion is provided with a first engagement portion that engages with the cover body at the first position to restrict movement of the support portion to the second position.
According to this aspect, when an unexpected load acts on the support part, the support part can be prevented from suddenly shifting from the stored position to the protruding position, thereby achieving stable space efficiency during distribution, when not in use, etc.

In the trigger-type liquid ejector of the above aspect, it is preferable that the cover body is configured to be able to overcome the support portion as the support portion moves between the first position and the second position, and that a second engagement portion is provided which engages with the support portion at the second position.
According to this aspect, during the ejection operation, it is possible to prevent the support part from unexpectedly moving toward the second position due to a load acting on the support part via the back of the hand, etc., thereby enabling a stable ejection operation.

In the trigger-type liquid ejector of the above aspect, it is preferable that the cover body is provided with a housing portion that houses the support portion at the second position.
According to this aspect, the support portion can be prevented from protruding rearward beyond the cover body when in the storage position.

According to this aspect of the present invention, it is possible to provide a trigger-type liquid ejector that is small and space-efficient while maintaining operability.

Embodiments of the present invention will be described below with reference to the drawings. In the embodiments and variations described below, the same reference numerals may be used to designate corresponding configurations, and descriptions thereof may be omitted.

First Embodiment
1 and 2, the trigger type liquid ejector 1 of this embodiment is capable of ejecting liquid contained in a container body A. The trigger type liquid ejector 1 comprises an ejector body 10, a nozzle member 11, a trigger portion 12, and a cover 14. Unless otherwise specified, each of the components of the trigger type liquid ejector 1 is a molded product made of synthetic resin such as an olefin-based resin.

The ejector body 10 includes a vertical supply tube section 20, an attachment cap 21, an ejection tube section 22, a relay member 23, a pump section 24, and a biasing member 25.

In the following, the direction along the axis O1 of the vertical supply tube section 20 (axial direction) is referred to as the up-down direction, with the bottom (not shown) side of the container body A along the up-down direction being referred to as the lower side, and the opposite side being referred to as the upper side. When viewed from the up-down direction, the direction that intersects with the axis O1 is referred to as the radial direction. Within the radial direction, the direction in which the vertical supply tube section 20 and the nozzle member 11 are lined up is referred to as the front-rear direction. Within the front-rear direction, the nozzle member 11 side relative to the vertical supply tube section 20 is referred to as the front side, and the opposite side is referred to as the rear side. Additionally, within the radial direction, the direction perpendicular to the front-rear direction when viewed from the up-down direction is referred to as the left-right direction.

The vertical supply tube section 20 is where the liquid pumped up from inside the container body A by the pump section 24 flows. The vertical supply tube section 20 is formed in a multi-stage cylindrical shape with the diameter decreasing the further up it is located. Specifically, the vertical supply tube section 20 has a small diameter section 20a located at the top and a large diameter section 20b connected to the bottom of the small diameter section 20a. The large diameter section 20b is provided with a flange section 20c that protrudes radially outward.

The attachment cap 21 is formed into a cylindrical shape that extends in the vertical direction. The attachment cap 21 is removably fastened to the mouth of the container body A with the flange portion 20c sandwiched between the attachment cap 21 and the upper end opening edge of the mouth portion (not shown). Note that the method of fixing the attachment cap 21 to the mouth portion may be a method other than a screw (e.g., fitting, etc.).

The injection tube portion 22 allows the liquid in the vertical supply tube portion 20 to flow toward the nozzle member 11. The injection tube portion 22 extends forward from the upper end of the vertical supply tube portion 20. A valve body (not shown) is provided between the vertical supply tube portion 20 and the injection tube portion 22 to allow the flow of liquid from the vertical supply tube portion 20 to the injection tube portion 22 and to regulate the flow of liquid from the injection tube portion 22 to the vertical supply tube portion 20.

The relay member 23 connects the injection tube portion 22 and the nozzle member 11. The relay member 23 is attached to the injection tube portion 22 from the front of the injection tube portion 22.

The pump portion 24 stores and pumps the liquid in the container body A in response to the movement of the trigger portion 12. The pump portion 24 includes a cylinder 31 and a piston 32.
The cylinder 31 is provided in front of the small diameter portion 20a of the vertical supply tube portion 20. The cylinder 31 is formed in a bottomed cylindrical shape that protrudes on both left and right sides of the vertical supply tube portion 20 (small diameter portion 20a) and opens forward.

The piston 32 is provided so as to be movable in the forward and backward directions relative to the cylinder 31. The piston 32 slides on the inner peripheral surface of the cylinder 31 as it moves forward and backward relative to the cylinder 31. The vertical supply tube section 20 is provided with a valve body (not shown) that allows the flow of liquid from inside the container body A to the cylinder 31 and regulates the flow of liquid from the cylinder 31 into the container body A.

The trigger portion 12 is provided in front of the pump portion 24 so as to be movable back and forth. Specifically, the trigger portion 12 includes a trigger body 12a, a support piece 12b, and a spring receiving portion 12c.
The trigger body 12a extends in front of the pump section 24, inclining forward from top to bottom. The trigger body 12a is the part that is gripped when performing a spraying operation, and an index finger or the like is hooked onto the trigger body 12a from the front. The front end of a piston 32 is connected to the vertical middle part of the trigger body 12a. That is, the piston 32 moves back and forth in accordance with the back and forth movement of the trigger body 12a.

A pair of support pieces 12b are provided on the left and right sides of the upper end of the trigger body 12a. The support pieces 12b extend upward on both the left and right sides of the relay member 23. The upper end of each support piece 12b is supported by the relay member 23 so as to be rotatable around an axis along the left and right direction. Therefore, the trigger part 12 is configured to be rotatable around an axis along the left and right direction with the upper end of each support piece 12b as a fulcrum.

A pair of spring receivers 12c are provided on the left and right sides of the trigger body 12a. The spring receivers 12c protrude from the trigger body 12a on both the left and right sides. Each spring receiver 12c is open upward and backward.

The biasing member 25 biases the trigger portion 12 forward. The biasing member 25 is U-shaped in a plan view. The biasing member 25 has a connection portion 25a and a pair of elastic portions 25b.

The connecting portion 25a is attached to the upper end portion of the vertical supply tube portion 20 (the boundary portion with the injection tube portion 22).
The elastic portions 25b extend forward from both left and right ends of the connecting portion 25a (only one of the elastic portions 25b is shown in FIG. 1). That is, the connecting portion 25a integrally connects the rear ends of the elastic portions 25b to each other. Each elastic portion 25b is disposed on both left and right sides of the vertical supply tube portion 20. In a side view, each elastic portion 25b has an arc shape that protrudes upward. Each elastic portion 25b passes above the cylinder 31 and reaches from the upper end of the vertical supply tube portion 20 to the front of the cylinder 31.

The front end (lower end) of the elastic portion 25b is accommodated in the spring receiving portion 12c in front of the cylinder 31. The elastic portion 25b is connected to the inner surface of the spring receiving portion 12c inside the spring receiving portion 12c. In the illustrated example, the elastic portion 25b is connected to the trigger portion 12 by abutting against the rearward facing surface of the inner surface of the spring receiving portion 12c. The elastic portion 25b is configured to be elastically deformable (flexibly deformable) in a direction perpendicular to the extension direction. In this embodiment, the elastic portion 25b flexibly deforms from the rear end, so that the front end is elastically displaced in the front-rear direction. Therefore, the elastic portion 25b is interposed between the upper end of the vertical supply tube portion 20 and the trigger portion 12, and biases the trigger portion 12 forward.

The nozzle member 11 is attached to the relay member 23 from the front. The nozzle member 11 is formed in a topped cylindrical shape that opens to the rear. The top wall portion 11a of the nozzle member 11 has an ejection hole 11b that penetrates the top wall portion 11a in the front-rear direction.

As shown in FIGS. 1 to 3, the cover 14 has a cover body 51 and a support portion 52 that are integrally formed.
The cover body 51 surrounds the portion of the ejector body 10 located above the mounting cap 21 from above, behind and sides, with the nozzle member 11 exposed.

The cover body 51 is formed in a box shape that opens toward the front. The ejector body 10 is inserted from the front into the inside of the cover body 51 with the nozzle member 11 facing forward. The ejector body 10 is assembled to the cover body 51 by being engaged, for example, by a claw or the like, inside the cover body 51.

The cover body 51 includes a top wall portion 51a, a rear wall portion 51b, a side wall portion 51c, and a bottom wall portion 51d.
The top wall portion 51a extends in the front-rear direction above the ejector body 10. The top wall portion 51a covers the ejector body 10 from above.

The rear wall portion 51b covers the ejector body 10 from the rear. The rear wall portion 51b extends at an incline rearward as it heads downward from the rear end edge of the top wall portion 51a. The rear wall portion 51b is formed with a storage portion 51f that penetrates the rear wall portion 51b in the front-to-rear direction. The storage portion 51f extends in the vertical direction in the rear wall portion 51b. The lower end opening edge of the storage portion 51f coincides with the lower end edge of the rear wall portion 51b. The upper end opening edge of the storage portion 51f is located above the vertical middle portion of the rear wall portion 51b.

The side wall portions 51c are disposed on both left and right sides of the ejector body 10. The outer peripheral edges of the side wall portions 51c are continuous with the left and right end edges of the top wall portion 51a and the rear wall portion 51b, respectively.
3 and 4, the bottom wall portion 51d protrudes in a brim-like shape from the lower edges of the rear wall portion 51b and the side wall portion 51c toward the inside of the cover body 51. In a plan view, the bottom wall portion 51d is formed in a U-shape that surrounds the upper end portion of the large diameter portion 20b from the rear and sides.

The support part 52 is integrally connected to the lower end opening edge of the storage part 51f (the boundary part between the rear wall part 51b and the bottom wall part 51d) via the hinge part 55. The hinge part 55 is integrally formed with the cover body 51 and the support part 52, and is a part formed to be thinner than the cover body 51 and the support part 52, and is configured to be elastically deformable. As a result, the support part 52 is configured to be rotatable around an axis along the left-right direction with the hinge part 55 as a starting point. In this embodiment, the hinge part 55 is formed over the entire area at the base end edge of the support part 52 except for both ends in the left-right direction. However, the hinge part 55 may be provided intermittently in the left-right direction.

The support portion 52 is formed in a plate shape extending from the cover body 51 in a cantilever manner. In this embodiment, the support portion 52 is formed in a semi-elliptical shape with a rounded tip. However, the external shape of the support portion 52 can be changed as appropriate, such as to a rectangular shape.

The support part 52 is configured to be rotatable around the hinge part 55 relative to the cover body 51 between a storage position (see FIG. 1) and a protruding position (see FIG. 2). The storage position is a state in which the support part 52 is stored in the storage part 51f. Specifically, in the storage position, the support part 52 extends in a forward inclined state as it extends upward from the lower opening edge of the storage part 51f. The tip of the support part 52 passes through the storage part 51f and reaches the inside of the cover body 51.

2 and 4, the protruding position is a state in which the support portion 52 protrudes rearward from the cover body 51 along the bottom wall portion 51d. In the protruding position, the support portion 52 is arranged with the vertical direction as the thickness direction. In the following description, the surface of the support portion 52 facing downward in the protruding position is referred to as the first surface, and the surface facing upward is referred to as the second surface. In the illustrated example, when the support portion 52 is in the protruding position, the first surface is arranged flush with the lower surface of the bottom wall portion 51d, and the second surface is arranged flush with the upper surface of the bottom wall portion 51d. In this embodiment, the support portion 52 is arranged parallel to the front-rear direction in the protruding position, but is not limited to this configuration. It is sufficient that the amount of protrusion of the support portion 52 rearward from the cover body 51 in the protruding position is greater than the amount of protrusion of the support portion 52 rearward from the cover body 51 in the stored position. In this case, the support portion 52 may be arranged at an angle, for example, with respect to the front-rear direction in the protruding position.

1 and 3, in the storage position, the movement of the support portion 52 to the protruding position is restricted by an engagement portion (first engagement portion) 61 provided on the cover body 51. The engagement portion 61 protrudes inward in the left-right direction from the side edge (the edge facing inward in the left-right direction) of the storage portion 51f. When the support portion 52 is in the storage position, the engagement portion 61 engages (contacts) with the tip portion of the support portion 52 from the rear of the support portion 52. The protruding amount of the engagement portion 61 is set to a height that the support portion 52 can overcome when the support portion 52 is moved to the protruding position (during a rotation operation). In addition, in the storage position, there is a gap S in the vertical direction between the upper end opening edge of the storage portion 51f and the tip portion of the support portion 52. The gap S functions as a finger insertion space when the support portion 52 is rotated.

2 to 4, ribs (second engagement portions) 62 are formed on the base end edge of the support portion 52 at portions located on both left and right sides of the hinge portion 55. The ribs 62 rotate around the hinge portion 55 together with the support portion 52 as the support portion 52 moves between the protruding position and the storage position, thereby climbing over the bottom wall portion 51d in the up-down direction. Specifically, when the support portion 52 is in the protruding position, the ribs 62 protrude upward from the second surface of the support portion 52 and extend in the front-to-rear direction. The front end portion of the ribs 62 protrudes forward from the base end edge of the support portion 52. When the support portion 52 is in the protruding position, the ribs 62 engage with the bottom wall portion 51d from above the bottom wall portion 51d, thereby restricting the movement of the support portion 52 from the protruding position to the storage position. As shown in Figures 1 and 3, when the support part 52 is in the storage position, the rib 62 engages with the bottom wall part 51d from the rear of the bottom wall part 51d, thereby restricting the movement of the support part 52 from the storage position to the protruding position.

As shown in FIG. 4, the rear end edge of the bottom wall portion 51d has clearance portions 65 formed in the portions located on both the left and right sides of the hinge portion 55. The clearance portions 65 penetrate the bottom wall portion 51d in the vertical direction and open on the rear end edge of the bottom wall portion 51d. The clearance portions 65 reduce the amount of overlap between the rib 62 and the bottom wall portion 51d, and are located on the movement path of the rib 62 when the support portion 52 rotates. Therefore, as the support portion 52 moves between the protruding position and the retracted position, the base end of the rib 62 passes inside the clearance portion 65 and the tip end passes over the rear end edge of the clearance portion 65, thereby climbing over the bottom wall portion 51d in the vertical direction.

Next, a case where the trigger-type liquid ejector 1 configured as described above is used will be described. In the following description, the initial state is assumed to be a state in which the support part 52 is in the storage position, and each part of the trigger-type liquid ejector 1 is filled with liquid.

As shown in Figures 1 to 3, when using the trigger-type liquid ejector 1, the support part 52 is first moved from the stored position to the protruding position. Specifically, a finger is inserted into the gap S and the finger is hooked on the second surface of the support part 52. In this state, when the support part 52 is pulled backward, the support part 52 rotates backward from the hinge part 55 as a starting point. Specifically, after the support part 52 climbs backward over the engagement part 61, the support part 52 further falls backward. Thereafter, the rib 62 climbs upward over the bottom wall part 51d in the process of passing through the relief part 65. As a result, the support part 52 is in the protruding position with the rib 62 engaging the bottom wall part 51d from above.

As shown in FIG. 2, when the support portion 52 moves to the protruding position, the support portion 52 protrudes rearward relative to the cover body 51. As a result, the first surface of the support portion 52 is positioned downward behind the mounting cap 21.

When performing the liquid ejection operation, the index finger or the like is hooked on the trigger portion 12 and the hand is placed around the attachment cap 21. In this state, the part of the back of the hand located between the thumb and index finger approaches or abuts from below against the first surface of the support portion 52. When the trigger portion 12 is pulled backward, the trigger portion 12 rotates around the support piece 12b as a fulcrum, and the trigger portion 12 moves backward. Then, the elastic portion 25b is pushed backward via the spring receiving portion 12c, and the elastic portion 25b is flexed and deformed. As a result, the elastic portion 25b is elastically displaced backward as the trigger portion 12 moves backward. As a result, a biasing force is applied to the trigger portion 12 in the forward direction.

When the trigger portion 12 moves rearward, the piston 32 moves rearward relative to the cylinder 31. Then, the inside of the cylinder 31 is pressurized, and the liquid inside the cylinder 31 is supplied into the vertical supply tube portion 20 (small diameter portion 20a). The liquid supplied into the vertical supply tube portion 20 reaches the relay member 23 through the injection tube portion 22. The liquid that reaches the relay member 23 flows into the nozzle member 11 and is then ejected through the ejection hole 11d.

When the pulling operation of the trigger portion 12 is released, the trigger portion 12 moves forward due to the restoring force of the elastic portion 25b. Accordingly, the piston 32 moves forward relative to the cylinder 31. This reduces the pressure inside the piston 32. This causes the liquid in the container body A to be sucked up into the vertical supply tube portion 20. The liquid sucked up into the vertical supply tube portion 20 can be introduced into the cylinder 31 in preparation for the next ejection operation.

As shown in Figures 1 and 2, after the ejection operation is completed, in order to return the support part 52 to the storage position, the support part 52 is pushed upward. Then, the support part 52 rotates upward from the hinge part 55 as a starting point. In the process of the support part 52 rotating toward the storage position, the rib 62 passes through the escape part 65 and climbs downward over the bottom wall part 51d. After that, by further pushing the support part 52 toward the storage position, the support part 52 climbs forward over the engagement part 61. As a result, the support part 52 is accommodated in the accommodation part 51f in a state where it is engaged with the engagement part 61. As a result, the support part 52 moves from the protruding position to the storage position. By the support part 52 moving to the storage position, the amount of protrusion of the cover 14 rearward from the attachment cap 21 becomes smaller.

In this manner, in this embodiment, the support portion 52 is configured to rotate between a protruding position in which it extends rearward relative to the cover body 51 and a retracted position that is disposed forward of the protruding position.
According to this configuration, by moving the support part 52 to the protruding position during the ejection operation, the ejection operation can be performed with the trigger type liquid ejector 1 supported on the back of the hand via the support part 52. This allows the trigger type liquid ejector 1 to be stably held, improving operability.
On the other hand, by moving the support part 52 to the storage position during distribution or when not in use, the amount of rearward protrusion of the cover 14 from the ejector body 10 can be reduced. This makes it possible to provide a small, space-efficient trigger-type liquid ejector 1. Furthermore, by making the cover 13 smaller, the amount of resin required to mold the cover 13 can be reduced, leading to cost reductions, etc.

In this embodiment, the cover body 51 is provided with the engagement portion 61 that engages with the support portion 52 in the storage position and restricts the movement of the support portion 52 from the storage position to the protruding position.
According to this configuration, it is possible to prevent the support part 52 from suddenly shifting from the stored position to the protruding position when an unexpected load acts on the support part 52. This makes it possible to achieve stable space efficiency during distribution, when not in use, etc.

In this embodiment, the cover body 51 is configured so that the support portion 52 can climb over it, and is provided with a rib 62 that engages with the support portion 52 in the storage position.
According to this configuration, during the ejection operation, it is possible to suppress the support part 52 from moving unexpectedly toward the storage position due to a load acting on the support part 52 via the back of the hand, etc. This makes it possible to perform a stable ejection operation.

In this embodiment, the cover body 51 is configured to have the accommodation portion 51f that accommodates the support portion 52 in the storage position.
According to this configuration, the support portion 52 can be prevented from protruding rearward beyond the cover body 51 when in the storage position.

Second Embodiment
In the trigger type liquid ejector 1 shown in FIGS. 5 and 6, the support portion 52 includes a base portion 100 and an extension portion 101.
5, the base portion 100 is formed in a plate shape extending in the left-right direction. The front end edge of the base portion 100 is rotatably connected to the bottom wall portion 51d via a hinge portion 55. At least both left-right end edges of the base portion 100 protrude outward in the left-right direction relative to the mounting cap 21.
The extension portion 101 extends in a cantilever manner from the base portion 100. The cross-sectional shape of the extension portion 101 is formed in an arc shape. However, the cross-sectional shape of the extension portion 101 may be linear.

The support portion 52 is configured to be rotatable between a storage position and a protruding position via the hinge portion 55. Specifically, when the support portion 52 is in the storage position shown in FIG. 5, the base portion 100 is disposed rearward of the bottom wall portion 51d and on the same plane as the bottom wall portion 51d. The extension portion 101 extends downward from the base portion 100. In the storage position, the extension portion 101 is disposed following the outer peripheral surface of the attachment cap 21.
6, the base portion 100 is accommodated in an accommodating portion 105 formed in the rear wall portion 51b. The accommodating portion 105 is formed by penetrating the lower end portion of the rear wall portion 51b in the front-rear direction. In the protruding position, the extension portion 101 extends rearward from the rear wall portion 51b.

The base portion 100 is formed with an engagement portion 111 that engages with the upper opening edge of the storage portion 105 when in the protruding position. The engagement portion 111 protrudes forward from the base portion 100. The engagement portion 111 is configured to be able to climb over the upper opening edge of the storage portion 105 as the support portion 52 moves between the storage position and the protruding position.

In the trigger-type liquid ejector 1 of this embodiment, to move the support part 52 from the stored position to the protruding position, a finger or the like is hooked on the tip (lower end) of the support part 52 and the support part 52 is pushed up. The support part 52 then rotates around the hinge part 55, causing the support part 52 to move upward. Then, the engagement part 111 climbs over the edge of the upper opening of the storage part 105, causing the base part 100 to be stored within the storage part 105. This causes the support part 52 to move to the protruding position.

In this embodiment as well, when performing the spraying operation, the index finger or the like is hooked on the trigger portion 12 and the hand is placed around the attachment cap 21. At this time, the support portion 52 is supported by the part of the back of the hand located between the thumb and index finger, allowing for a stable spraying operation. After the spraying operation is completed, in order to return the support portion 52 to the storage position, the support portion 52 is pushed downward. This causes the support portion 52 to rotate around the hinge portion 55, causing the engagement portion 111 to climb over the edge of the upper opening of the storage portion 105. As a result, the support portion 52 moves to the storage position.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Addition, omission, substitution, and other modifications of the configuration are possible without departing from the spirit of the present invention.
