DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0016] As shown in Fig. 1, in one embodiment of the present invention, a trigger-type sprayer 1 (hereinafter also referred to as sprayer 1) is attached to a mouth portion 2a of a container body 2 to form a spray container 3. In other words, the spray container 3 has the sprayer 1 and a container body 2. The sprayer 1, attached to the mouth portion 2a of the container body 2, can spray the contents in the container body 2 from a spray outlet 5 by operating a trigger 4 through a pulling operation.

[0017] The container body 2 has a cylindrical mouth 2a centered on a central axis O, a body 2b connected to the lower end of the mouth 2a, and a bottom 2c connected to the lower end of the body 2b. Note that the mouth 2a may have a tubular shape other than a cylindrical shape, such as a square tubular shape.

[0018] For ease of explanation, the direction along the central axis O of the mouth 2a is also referred to as the up-down direction, the direction from the bottom 2c toward the mouth 2a along the up-down direction is also referred to as the upward direction, the opposite direction is also referred to as the downward direction, the direction perpendicular to the up-down direction and the actuation direction of the trigger 4 is also referred to as the left-right direction, and the direction perpendicular to the up-down direction and the left-right direction is also referred to as the front-rear direction.

[0019] Liquid contents are contained in the container body 2, and the ejector 1 ejects the contents in a mist form. Note that the ejector 1 is not limited to a configuration that ejects liquid contents in a mist form, and may be configured to eject liquid contents in a foam or straight form, or may be configured to eject contents other than liquid, such as powder.

[0020] The ejector 1 has a main body 6, an attachment cap 7, a trigger 4, and an ejection nozzle 8. The main body 6 has a connection part 9 having an outlet 9a, an internal flow path 10 (see FIG. 2), and a pump mechanism 11 that sends the contents in the container body 2 to the outlet 9a of the connection part 9 through the internal flow path 10 by the operation of the trigger 4, and is attached to the container body 2 by attaching the attachment cap 7 to the mouth part 2a. The trigger 4 is supported by the main body 6 so as to be rotatable around a rotation axis P extending in the left-right direction. In other words, the operation direction of the trigger 4 is the circumferential direction (the direction shown by the two-dot chain arrow in FIG. 1) around the rotation axis P. Note that the trigger 4 is not limited to being supported by the main body 6 so as to be rotatable, and may be supported by the main body 6 so as to be slidable, for example. The ejection nozzle 8 is connected to the connection part 9 of the main body 6.

[0021] As shown in Figs. 2 to 4, the jet nozzle 8 has a nozzle 12 having a nozzle base 12a, a flexible tube 12b, and a nozzle tip 12c, a guided portion 13 connected to the nozzle tip 12c, a guide portion 14 consisting of a pair of guide plates 14a, and an attachment cap 15. The jet nozzle 8 is an assembly formed by assembling a nozzle main body member 8a, a guide member 8b, a guided member 8c, and an ejection port member 8d. The nozzle 12 is made up of the nozzle main body member 8a and the ejection port member 8d, and the nozzle tip 12c is made up of the tip of the nozzle main body member 8a and the ejection port member 8d. The guided portion 13 is made up of the guided member 8c. The guide member 8b is made up of the guide portion 14 and the attachment cap 15.

[0022] The nozzle body member 8a is made of soft resin such as high density polyethylene (HDPE) or low density polyethylene (LDPE, soft polyethylene) and has elasticity. Note that it may be made of elastomer or rubber instead of resin. The guide member 8b, the guided member 8c and the ejection port member 8d are made of resin, for example.

[0023] The nozzle base 12a is fluidly and structurally connected to the connection part 9 of the main body 6, the flexible tube 12b connects the nozzle base 12a and the nozzle tip 12c, the nozzle tip 12c has a nozzle outlet 5 formed by the nozzle outlet member 8d, and inside the nozzle 12, a nozzle flow path 12d is formed that connects the outlet 9a of the connection part 9 to the nozzle outlet 5. The nozzle outlet member 8d has a cylindrical peripheral wall 16 centered on the axis R of the nozzle 12, and an end wall 17 connected to one end of the peripheral wall 16 and having the nozzle outlet 5, and is fitted into a fitting hole in the tip surface of the nozzle main body member 8a from the other end side of the peripheral wall 16. A groove is provided between the inner surface of the nozzle outlet member 8d and the nozzle main body member 8a to spray the contents from the nozzle outlet 5 in a mist form.

[0024] In a natural state where the nozzle 12 is not elastically deformed, the nozzle 12 takes a neutral posture in which it extends linearly along a neutral axis Q parallel to the front-rear direction in a plane perpendicular to the left-right direction. That is, in the neutral posture, the axis R of the nozzle 12 coincides with the neutral axis Q. Note that the nozzle 12 is not limited to a configuration in which the neutral axis Q is parallel to the front-rear direction, and may be configured, for example, in such a manner that the neutral axis Q is inclined with respect to the front-rear direction in a plane perpendicular to the left-right direction.

[0025] With regard to the connecting portion 9 and the guiding member 8b, the side toward the tip along the neutral axis Q is also referred to as the tip side, and the opposite direction is also referred to as the base side. With regard to the nozzle 12 and the guided member 8c, the side toward the tip along the axis R of the nozzle 12 is also referred to as the tip side, and the opposite direction is also referred to as the base side.

[0026] The connection part 9 has a flow path wall 9b, a hollow column part 9c that protrudes from the flow path wall 9b to the tip side (front side) and is centered on a neutral axis Q, and a cylindrical outer tube part 9d that protrudes from the flow path wall 9b to the tip side radially outside of the hollow column part 9c and is centered on the neutral axis Q. The flow path wall 9b has an outlet 9a between the hollow column part 9c and the outer tube part 9d.

[0027] The nozzle base 12a has a base tube 18 that fits into the outer circumferential surface of the hollow columnar portion 9c, a flange 19 that extends radially outward from a portion between the tip and base ends of the base tube 18, and a cylindrical body 20 that protrudes from the flange 19 toward the base end side (rear side) and is centered on the neutral axis Q. A groove that connects the outlet 9a to the nozzle flow path 12d is provided between the inner circumferential surface of the base tube 18 and the outer circumferential surface of the hollow columnar portion 9c. The outer circumferential edge of the flange 19 abuts against the tip surface of the outer tubular portion 9d of the connection portion 9, and the outer circumferential surface of the body 20 abuts against the inner circumferential surface of the outer tubular portion 9d.

[0028] The mounting cap 15 has a rectangular plate-shaped tip wall 15a having an opening centered on the neutral axis Q, a cylindrical inner wall 15b protruding from a portion between the inner peripheral edge and the outer peripheral edge of the tip wall 15a toward the base end side and centered on the neutral axis Q, and a square cylindrical outer wall 15c protruding from the outer peripheral edge of the tip wall 15a toward the base end side and centered on the neutral axis Q. When the tip wall 15a is placed over the flange 19, the inner peripheral surface of the inner peripheral wall 15b is engaged with the outer peripheral surface of the outer cylinder portion 9d by engagement via a concave-convex shape. The mounting cap 15 is assembled to the nozzle body member 8a by engaging the inner peripheral edge of the tip wall 15a with the outer peripheral surface of the tip portion of the base cylinder 18 by engagement via a concave-convex shape. The inner peripheral surface of the outer peripheral wall 15c has a rotation stopper portion 15d consisting of a recess that accommodates a protrusion protruding radially outward from the outer cylinder portion 9d. When the protrusion comes into contact with the anti-rotation portion 15d, the relative rotation of the mounting cap 15 with respect to the connection portion 9 about the neutral axis Q is restricted.

[0029] The pair of guide plates 14a are provided on both sides of the nozzle 12 in the left-right direction, and each of them is attached via an attachment cap 15. Nozzle base 12a The guide plate 14a is connected to one of the two end edges of the tip wall 15a in the left-right direction and is perpendicular to the left-right direction. One guide plate 14a is connected to one of the two end edges of the tip wall 15a in the left-right direction, and the other guide plate 14a is connected to the other end edge of the tip wall 15a in the left-right direction. Each of the pair of guide plates 14a has an arc-shaped edge 21 that is arc-shaped when viewed in the left-right direction, and when the nozzle 12 is in a neutral position, the guided portion 13 connected to the nozzle tip portion 12c abuts on the center of each of the arc-shaped edges 21 of the pair of guide plates 14a. Each of the arc-shaped edges 21 extends over approximately half the circumference. The guided portion 13 can slide on each of the arc-shaped edges 21 of the pair of guide plates 14a in a plane perpendicular to the left-right direction while bending and deforming the flexible tube 12b. In other words, the pair of guide plates 14a (guiding portion 14) guides the guided portion 13 so that it can slide in a plane perpendicular to the left-right direction.

[0030] The guided member 8c constituting the guided portion 13 has a cylindrical engagement tube 22 having an inner peripheral surface that is engaged with the outer peripheral surface of the tip of the nozzle main body member 8a by engagement via a concave-convex shape, a guided plate 23 that protrudes from the base end of the engagement tube 22 on both sides in the left-right direction, and an outer wall 24 that protrudes from the outer peripheral edge of the guided plate 23 toward the tip side. The outer peripheral surface of the tip of the nozzle main body member 8a is a cylindrical surface centered on the axis R and has a size corresponding to the inner peripheral surface of the engagement tube 22. The outer peripheral surface of the tip of the nozzle main body member 8a engages with the inner peripheral surface of the engagement tube 22 by engagement via a concave-convex shape so as to restrict the engagement tube 22 from moving toward the tip side along the neutral axis Q. The guided plate 23 has a rectangular outer shape when viewed from the direction along the axis R, and slidably abuts against the arc-shaped edges 21 of the pair of guide plates 14a at both left-right edges of the base end surface. The guided plate 23 has a curved plate shape that is curved in an arc shape following the arc-shaped edges 21 of the pair of guide plates 14a when viewed in the left-right direction.

[0031] The user can pinch the outer wall 24 and slide the guided member 8c on the arcuate edges 21 of the pair of guide plates 14a in the upward tilt direction (see FIG. 5), thereby bending and deforming the flexible tube 12b and moving the tip of the nozzle 12 together with the guided member 8c, thereby changing the orientation of the nozzle 5 to the upward tilt direction. Conversely, the orientation of the nozzle 5 can be changed to the downward tilt direction by sliding the guided member 8c in the downward tilt direction (see FIG. 6).

[0032] In addition, the direction perpendicular to the left-right direction and the direction along the neutral axis Q is also called the tilt direction, the direction toward the upper side along the tilt direction is also called the upper tilt direction, and the opposite side is also called the lower tilt direction.

[0033] 2 to 5, the pair of guide plates 14a (guiding portions 14) hold the guided member 8c (guided portion 13) by engagement via the concave and convex shapes at each of a plurality of positions in a plane perpendicular to the left-right direction. More specifically, the pair of guide plates 14a have a group of convex ribs 25, the guided plate 23 has a pair of engaging protrusions 26, and the pair of guide plates 14a hold the guided member 8c by engagement between the group of convex ribs 25 and the pair of engaging protrusions 26 at each of a plurality of positions in a plane perpendicular to the left-right direction.

[0034] The convex rib group 25 includes a plurality of (three in this embodiment) tilt direction upper ribs 25a (hereinafter also referred to as upper ribs 25a) provided on the inner surface in the left-right direction of one guide plate 14a (the surface facing the other guide plate 14a) above the neutral axis Q in the tilt direction. The pair of engagement protrusions 26 includes one engagement protrusion 26 that is provided on the base end surface of the guided plate 23 and can selectively engage with each of the upper ribs 25a of one guide plate 14a. The multiple upper ribs 25a are arranged side by side in the tilt direction and each extend in a direction along the neutral axis Q. When viewed in the left-right direction, a gap is provided between the tip end of each upper rib 25a and the arc-shaped edge 21 to allow one engagement protrusion 26 to overcome the upper rib 25a in the tilt direction by elastic deformation of the flexible tube 12b, etc.

[0035] The convex rib group 25 also includes a plurality of (three in this embodiment) tilt direction lower ribs 25b (hereinafter also referred to as lower ribs 25b) provided on the inner surface in the left-right direction of one guide plate 14a below the neutral axis Q in the tilt direction. The lower ribs 25b are provided symmetrically to the upper ribs 25a with respect to a plane that includes the neutral axis Q and is perpendicular to the tilt direction. Therefore, one engagement protrusion 26 can selectively engage with each of the lower ribs 25b of one guide plate 14a.

[0036] Between the upper rib 25a on the lowest side in the tilting direction and the lower rib 25b on the highest side in the tilting direction, a gap is provided in the tilting direction so that the one engaging protrusion 26 can be sandwiched between these ribs. The one engaging protrusion 26 is provided on the axis R of the nozzle 12 when viewed in the left-right direction. Therefore, by sandwiching the one engaging protrusion 26 between the above-mentioned ribs, the nozzle 12 is maintained in a neutral position, and as a result, the direction of the nozzle 5 is maintained in a direction toward the tip side along the neutral axis Q. By applying a force to the guided member 8c in the upward tilting direction from this state, the one engaging protrusion 26 can be made to overcome the upper rib 25a on the lowest side in the tilting direction by the elastic deformation of the flexible tube 12b, etc., and the nozzle 12 can be deformed so as to be tilted upward in the tilting direction from the neutral position.

[0037] Then, by bringing one of the engagement protrusions 26 into contact with the upper surface of the upper rib 25a located at the lowermost position in the tilt direction, the guided member 8c can be held at a first position on the upper side in the tilt direction. Also, by further tilting the nozzle 12 and bringing one of the engagement protrusions 26 into contact with the upper surface of the upper rib 25a located at the uppermost position in the tilt direction, the guided member 8c can be held at a second position on the upper side in the tilt direction. Furthermore, by further tilting the nozzle 12 and bringing one of the engagement protrusions 26 into contact with the upper surface of the upper rib 25a located at the uppermost position in the tilt direction, the guided member 8c can be held at a third position on the upper side in the tilt direction, as shown in FIG. 5. Therefore, the direction of the nozzle 5 can be changed stepwise to the upper side in the tilt direction.

[0038] In addition, by applying a force to the guided member 8c in the tilting direction downward from the state where the nozzle 12 is in the neutral position, the nozzle 12 can be tilted downward in the tilting direction from the neutral position, and the guided member 8c can be selectively held at the first position, the second position, or the third position on the lower side in the tilting direction. Therefore, the orientation of the ejection port 5 can be changed stepwise to the tilting direction downward.

[0039] In order to hold the guided member 8c more stably at a plurality of positions (seven positions in this embodiment), a plurality of upper ribs 25a and a plurality of lower ribs 25b are also provided on the inner surface in the left-right direction of the other guide plate 14a, symmetrically with respect to a plane including the neutral axis Q and perpendicular to the left-right direction, and the other engaging protrusion 26 is provided on the base end surface of the guided plate 23. In other words, the convex rib group 25 is made up of a plurality (three) of upper ribs 25a and a plurality (three) of lower ribs 25b of one guide plate 14a, and a plurality (three) of upper ribs 25a and a plurality (three) of lower ribs 25b of the other guide plate 14a, and a pair of engaging protrusions 26 is made up of one engaging protrusion 26 and the other engaging protrusion 26.

[0040] According to this embodiment, the nozzle 12 can be deformed to change the direction of the outlet 5 in a plane perpendicular to the left-right direction, so there is no need to twist the handle significantly when spraying downward or upward. For example, when spraying toward the front side of the bathtub, it is usually necessary to spray in an inverted position with the container body 2 facing up, but by changing the angle of the nozzle 12 downward, spraying can be achieved by tilting it slightly. In addition, as shown in FIG. 6, spraying can be easily achieved in a recessed position such as the back side of the edge of a toilet bowl. Furthermore, when the nozzle 12 is facing upward, spraying can be achieved toward the back side of a leaf without squatting or twisting the hand to put the spray container 3 in an inverted position when gardening, etc. In this way, according to this embodiment, the outlet 5 can be easily directed in a desired direction in a plane perpendicular to the left-right direction.

[0041] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention.

[0042] Therefore, the trigger type ejector 1 of the above-described embodiment can be modified in various ways, for example as described below.

[0043] The trigger type sprayer 1 of the above-mentioned embodiment has a nozzle 12 with an outlet 5, and is a trigger type sprayer 1 that is attached to the mouth 2a of the container body 2 and can spray the contents inside the container body 2 from the outlet 5 by operating the trigger 4 through a pulling operation while attached to the mouth 2a of the container body 2. When the direction along the central axis O of the mouth 2a is defined as the up-down direction, and the direction perpendicular to the up-down direction and the operating direction of the trigger 4 is defined as the left-right direction, various modifications can be made as long as the nozzle 12 is a trigger type sprayer 1 that can be deformed to change the direction of the outlet 5 within a plane perpendicular to the left-right direction.

[0044] For example, the number and arrangement of the convex rib group 25 can be changed as appropriate. The number of tilt direction upper ribs 25a provided on one guide plate 14a can be changed as appropriate to match the number of tilt direction upper ribs 25a provided on the other guide plate 14a. Also, the number of tilt direction lower ribs 25b provided on one guide plate 14a can be changed as appropriate to match the number of tilt direction lower ribs 25b provided on the other guide plate 14a. A configuration in which only the tilt direction lower ribs 25b are provided without providing the tilt direction upper ribs 25a, or a configuration in which only the tilt direction upper ribs 25a are provided without providing the tilt direction lower ribs 25b, may be used. A configuration in which the tilt direction upper ribs 25a and / or the tilt direction lower ribs 25b are provided only on one guide plate 14a may be used.

[0045] The trigger type ejector 1 is not limited to a configuration in which one guide plate 14a has a plurality of tilt direction upper ribs 25a and a plurality of tilt direction lower ribs 25b aligned in the tilt direction, and the guided portion 13 has an engagement protrusion 26 that can selectively engage with each of the plurality of tilt direction upper ribs 25a and each of the plurality of tilt direction lower ribs 25b. For example, as in a modified example shown in Figures 7 to 9, the trigger type ejector 1 may be configured such that one guide plate 14a has a plurality (three) tilt direction upper convex parts 27a (hereinafter also referred to as upper convex parts 27a) aligned in the tilt direction and a plurality (three) tilt direction lower convex parts 27b (hereinafter also referred to as lower convex parts 27b) aligned in the tilt direction, and the guided portion 13 can selectively engage with each of the plurality of upper convex parts 27a and each of the plurality of lower convex parts 27b. In this modification, when the nozzle 12 is in a neutral position, the guided portion 13 engages with the upper convex portion 27a located at the lowermost position in the tilt direction and the lower convex portion 27b located at the uppermost position in the tilt direction. In this modification, the other guide plate 14a is also provided with a plurality of upper convex portions 27a and a plurality of lower convex portions 27b symmetrically with respect to a plane that includes the neutral axis Q and is perpendicular to the left-right direction. The number and arrangement of the convex portion groups 27 consisting of the plurality (three) upper convex portions 27a and the plurality (three) lower convex portions 27b of one guide plate 14a and the plurality (three) upper convex portions 27a and the plurality (three) lower convex portions 27b of the other guide plate 14a can be appropriately changed in the same manner as in the case of the convex rib group 25.

[0046] The guide portion 14 may be configured to hold the guided portion 13 at each of a plurality of positions in a plane perpendicular to the left-right direction by engagement via an uneven shape that does not include the convex rib group 25 or the convex portion group 27. The guide portion 14 may be configured to hold the guided portion 13 at each of a plurality of positions by means other than engagement via an uneven shape, for example, frictional force. The guide portion 14 is not limited to a configuration that guides the guided portion 13 slidably in a plane perpendicular to the left-right direction, but may be configured to guide the guided portion 13 movably in a plane perpendicular to the left-right direction. The guide portion 14 is not limited to a configuration that is composed of a pair of guide plates 14a. The ejection nozzle 8 is not limited to a configuration that has the guide portion 14. The nozzle 12 is not limited to a configuration that extends linearly in a natural state. The flexible tube 12b is not limited to a configuration that has elasticity. The nozzle 12 is not limited to a configuration that has a flexible tube 12b.

[0047] In addition, in the above-mentioned embodiment of the trigger type sprayer 1, in the above configuration, it is preferable that the nozzle 12 is a trigger type sprayer 1 having a nozzle base 12a, a nozzle tip 12c having an ejection port 5, and a flexible tube 12b connecting the nozzle base 12a and the nozzle tip 12c.

[0048] In the above-described embodiment, the trigger type ejector 1 is preferably a trigger type ejector 1 having a guide portion 14 that guides the guided portion 13 connected to the nozzle tip portion 12c movably within a plane perpendicular to the left-right direction.

[0049] In the above-described embodiment of the trigger type ejector 1, in the above configuration, it is preferable that the guide portion 14 holds the guided portion 13 by engagement via the uneven shape at each of multiple positions in a plane perpendicular to the left-right direction.

[0050] In the trigger type ejector 1 of the embodiment described above, in the above configuration, the guide portions 14 are provided on both sides of the nozzle 12 in the left-right direction, Nozzle base 12a It is preferable that the trigger-type ejector 1 is composed of a pair of guide plates 14a perpendicular to the left-right direction and connected to each other, each of the pair of guide plates 14a having an arc-shaped edge 21 that is arc-shaped when viewed in the left-right direction, and when the nozzle 12 is in a neutral position extending linearly along the neutral axis Q in a plane perpendicular to the left-right direction, the guided portion 13 abuts against the center of each of the arc-shaped edges 21 of the pair of guide plates 14a.
