[0002] A known trigger-type dispenser has a rotatable nozzle portion disposed in front of the discharge port of the dispenser body, a linking arm extending from the nozzle portion in a direction perpendicular to the axis of rotation, and the linking arm rotates between a locked position that stops the swinging of the trigger and an unlocked position that releases the swinging as the nozzle portion rotates (Patent Document 1). The dispenser body is provided with a shroud (cover member) having a flat top portion, and when refilling the container, the dispenser removed from the container can be turned upside down and temporarily placed on the floor or table. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 3730029 Summary of the Invention [Problem to be solved by the invention]

[0004] The dispenser of Patent Document 1 is unstable because only the top part of the shroud touches the ground when it is upside down during refilling, and there is a possibility that it may tip over due to vibration or the like, accidentally contaminating the surrounding area with the contents.

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a trigger type dispenser that can be stably inverted. [Means for solving the problem]

[0006] The first means comprises a dispenser main body 2 which can be attached to the mouth and neck of a container body, has a discharge port 4b which is a front opening and communicates with the mouth and neck when attached, has a trigger 7 which can swing back and forth hanging down from the discharge port 4b, and is configured such that by swinging the trigger 7, liquid can be sucked up from within the container body and discharged from the discharge port 4b; a nozzle member 10 in which a linking arm 16 extends from a nozzle portion 12 rotatably disposed in front of the discharge port 4b in a direction perpendicular to the rotation axis of the nozzle portion 12, and the linking arm 16 is arranged so as to be rotatable between a locked position that prevents the trigger 7 from swinging and an unlocked position that releases the trigger 7 from swinging by the rotation of the nozzle portion 12; A trigger-type dispenser having a main grounding portion A formed at the top of the dispenser main body 2 for grounding the dispenser main body 2 to an external mounting surface M in an inverted state, The linking arm 16 is formed so as to protrude outwardly from the nozzle portion 12 when in the unlocked position, A sub-grounding portion B is provided on the linking arm 16, which is positioned on the top surface S of the linking arm 16 when it is in this outwardly protruding state, and which can support the inverted position of the dispenser main body 2 together with the main grounding portion A by grounding it to the placement surface M in the inverted state.

[0007] In this means, a nozzle portion 12 is rotatably arranged in front of the discharge port 4b of the discharger main body 2 shown in Figure 1 (A), and a linking arm 16 extending from this nozzle portion rotates between a locked position shown by an imaginary line in Figure 2 and an unlocked position shown by a solid line by the rotation of the nozzle portion. Further, a main grounding portion A is formed on the top of the dispenser main body 2, and a sub-grounding portion B is formed on the top surface S side of the linking arm 16 when the linking arm 16 is in the unlocked position. In this structure, the main grounding portion A of the dispenser main body 2 and the sub-grounding portion B provided on the top surface S side of the linking arm 16 improve the stability of the trigger type dispenser in the inverted state.

[0008] The second means includes the first means, and the main ground portion A and the sub ground portion B are arranged horizontally on approximately the same plane.

[0009] In this embodiment, as shown in Figs. 2, 3(A) and 4(A), the main ground portion A and the sub ground portion B are arranged horizontally on approximately the same plane. This structure reduces wobbling of the trigger-type dispenser when in an inverted position, and further improves its stability.

[0010] The third means includes the first means or the second means, and includes a reinforcing rib 18 extending in the longitudinal direction of the linking arm 16 protruding from the top surface S of the linking arm 16 in the state of protruding outward to the side, and an end surface of the reinforcing rib in the protruding direction is defined as the secondary ground contact portion B; The auxiliary grounding portion B and the main grounding portion A are formed so as to be on the same horizontal plane when viewed from the outside.

[0011] In this means, as shown in Figure 3(A), a reinforcing rib 18 extending in the longitudinal direction of the linking arm 16 is protruded from the top surface S of the linking arm 16 when it is protruding outward to the side, and the end face of this reinforcing rib in the protruding direction is made into the secondary grounding portion B. Moreover, the auxiliary grounding portion B and the main grounding portion A are formed so as to be on the same horizontal plane when viewed from the outside. According to this structure, the end faces of the reinforcing ribs 18 extending in the longitudinal direction of the linking arm 16 serve as secondary ground contact portions B, thereby increasing resistance to external forces that tend to tip over the inverted dispenser.

[0012] The fourth means includes the first means or the second means, and is provided with an auxiliary rib 20 protruding from the top surface S of the linking arm 16 in the state of protruding outward to the side, at the tip side of the linking arm 16, and the end surface of the auxiliary rib 20 in the protruding direction is the secondary ground contact portion B; The auxiliary grounding portion B and the main grounding portion A are formed so as to be on the same horizontal plane when viewed from the outside.

[0013] In this method, an auxiliary rib 20 is protruded from the top surface S of the linking arm 16 when it is in the outward protruding state as shown in Figure 4 (A) at the tip side of the linking arm 16, and the end face of this auxiliary rib 20 in the protruding direction is made into the secondary grounding portion B. Moreover, the auxiliary grounding portion B and the main grounding portion A are formed so as to be on the same horizontal plane when viewed from the outside. According to this structure, by making the end face of the auxiliary rib 20 located on the tip side of the linking arm 16 into the secondary grounding portion B, it is possible to suppress wobbling of the dispenser and provide a more stable inverted state.

[0014] The fifth means has the first means or the second means, and when the linking arm 16 is rotated 90° from the locked position, it reaches the unlocked position, and is perpendicular to the axis O of the dispenser body 2 when viewed from the front in an inverted state.

[0015] In this embodiment, the link arm 16 is in the unlocked position when rotated 90 degrees from the locked position. When viewed from the front in an inverted state, the link arm 16 is arranged at a right angle to the axis O of the dispenser main body 2. In this configuration, by rotating the linking arm 16 90° from the locked position, the link between the main grounding portion A and the secondary grounding portion B can ensure the stability of the dispenser in an inverted state. Effect of the Invention

[0016] According to the present invention, the trigger-type dispenser can be inverted in a stable state, which is efficient in the refilling operation of the container body. [Brief description of the drawings]

[Figure 4] The configuration of a trigger-type dispenser according to a third embodiment of the present invention is shown in an unlocked state, where (A) is a front view of the dispenser in an unlocked state, and (B) is an explanatory diagram of the operation of the dispenser in an inverted state on an external mounting surface. BEST MODE FOR CARRYING OUT THEINVENTION

[0018] 1 and 2 show a trigger type dispenser according to a first embodiment of the present invention. The trigger type dispenser is used by being attached to the mouth and neck part of a container body (not shown). The trigger type dispenser is composed of a dispenser body 2 and a nozzle member 10. Each of these members can be made of, for example, synthetic resin or metal.

[0019] The dispenser body 2 is a member attached to the mouth and neck of the container body, and has a forward opening discharge port 4b at a position higher than the attachment point. A known structure can be appropriately adopted for the internal mechanism of the dispenser body (the flow path portion from the mouth and neck to the discharge port). In this specification, the left side of FIG. 1(A) will be referred to as "front", the right side as "rear", and the directions perpendicular to the paper surface as "left and right". In this embodiment, the dispenser body 2 includes an attachment cap 3, a body portion 4, a piston 6, a trigger 7, and a shroud 8. The attachment cap 3 is a cylindrical body that can be fitted onto the outer surface of the mouth and neck part. The body 4 stands upright from the mounting cap 3. The body 4 includes at least a vertical supply tube portion (not shown) extending upward from inside the mounting cap 3, a horizontal cylinder 4a protruding forward from the vertical middle portion of the vertical supply tube portion, and a horizontal supply tube portion (not shown) extending forward from the upper end of the vertical supply tube passage, and the discharge port 4b opens at the front end side of the horizontal supply tube portion. Check valves (not shown) are provided upstream and downstream of the vertical supply tube passage's communication with the horizontal cylinder 4a. The piston 6 is disposed inside the horizontal cylinder 4a so as to be movable forward and backward. A connecting portion (connecting rod) 6a for connecting to a trigger (described later) is provided protruding forward from the piston 6. The trigger 7 is supported at its upper end at a suitable position near the discharge port 4b (joint portion 11, described later, in the illustrated example) and hangs down so as to be swingable in the front-rear direction. A biasing means f (a spring in the illustrated example) for biasing the trigger 7 forward is interposed between the trigger 7 and the body portion 4. By swinging the trigger 7, the liquid is sucked up from the container body and discharged from the discharge port 4b. In the illustrated example, a pair of left and right vertical plates 5 are provided on both sides of the biasing means f. These vertical plates may be omitted. The shroud 8 is a cover member that covers the upper surface and the left and right side surfaces of the body portion 4. It is desirable to provide a stopper means (not shown) between the shroud 8 and the body portion 4 to prevent the shroud 8 from slipping out. The shroud 8 in the illustrated example includes a horizontal and flat zenith plate 8a that is long in the front-rear direction, and a pair of side plates 8b that are vertically extended from both the left and right sides of the zenith plate 8a. The side plate 8b in the illustrated example has an upward step portion i. The upper surface of the zenith plate 8a is the main grounding part A for grounding the inverted state of the dispenser main body 2 to the external mounting surface M. However, if the inverted state of the dispenser main body 2 can be stably supported when grounded to the mounting surface M, it is not necessary to make the entire surface of the zenith plate 8a of the shroud 8 the main grounding part A, and this structure can be modified as appropriate. For example, the shroud 8 may be omitted, and the zenith part of the body part 4 may be formed into a horizontal flat part, and the upper surface of this flat part may be the main grounding part A, or the zenith plate 8a of the shroud 8 or the zenith part of the body part 4 may be a partial flat surface. In the illustrated example, the main ground contact portion A is formed on a ground contact surface portion having a certain extent (ground contact area), but this form can also be changed as appropriate. For example, the main ground contact portion A may be formed by multiple (e.g., three or more) ground contact points located on the same imaginary horizontal plane.

[0020] The nozzle member 10 is a member that is attached to the body portion 4 in the vicinity of the discharge port 4b, and in this embodiment, is formed of a joint portion 11 and a nozzle portion 12, as shown in FIG. The joint portion 11 is a substantially cylindrical member having a function of connecting the nozzle portion 12 to the body portion 4 while maintaining communication with the discharge port 4b. In the illustrated example, a pair of left and right hook-shaped bearings R are provided below the joint part 11. The upper end of the trigger is divided into a pair of left and right bifurcated parts, and the swing shaft 7a protruding from each part is engaged with the bearings R.

[0021] The nozzle portion 12 is a nozzle head having a nozzle port 15 that opens forward and communicates with the discharge port 4b. A linking arm 16, which will be described later, is connected to the nozzle portion 12, and is formed so that the linking arm 16 can be gripped and rotated. The nozzle portion 12 in the illustrated example is composed of a head body 13 having a nozzle port 15 and rotatably supported by the joint portion 11, which is configured as an opening / closing part that opens and closes the communication between the discharge port and the nozzle port 15 by this rotation, and a nozzle cover 14 that is fitted onto the outer surface of the head body 13 and connected to a linking arm 16. However, this configuration can be modified as appropriate, and the link arm 16 may be directly connected to the head body 13 .

[0022] The linkage arm 16 is a rotation stopper that has the function of locking the forward and backward movement of the trigger, and can rotate together with the nozzle portion 12 through a certain angle (90° in the illustrated example) between the position shown by the solid line in Figure 2 (unlocked position) and the position shown by the imaginary line (locked position). That is, the linking arm 16 is structured to stop at a position that is approximately perpendicular (L-shaped) to the axis O of the dispenser main body 2 when viewed from the front. In the illustrated example, when the trigger-type dispenser is in use, the top surface S of the linking arm, which will be described later, becomes approximately horizontal. Although not shown, the linking arm may be configured to become in the unlocked position when rotated 90° or more from the locked position. In the illustrated example, as shown in FIG. 2(B), the linking arm 16 is L-shaped and is composed of a base portion 16a extending laterally from the nozzle portion 12 when viewed from above, and a horizontal tip portion 16b extending rearward. In this specification, the position where the movement of the trigger 7 is restricted by the engaging portion 24 of the linking arm 16 described below (the position shown by the imaginary line in FIG. 2 in the illustrated example) is referred to as the "locked position," while the position where the engaging portion 24 is farthest from the trigger 7 (the position shown by the solid line in FIG. 2 in the illustrated example) is referred to as the "unlocked position." The unlocked position in the illustrated example is the position where the linking arm 16 protrudes outwardly to the side from the nozzle portion 12. Although not shown, a positioning means (for example, a protruding and recessed means that engages with each other when the linking arm is rotated to the unlocked position) for maintaining the linking arm 16 protruding outward may be provided in an appropriate location. As shown in FIG. 1(B), the linking arm 16 has a plate-shaped extension portion 22 extending from an arm portion that protrudes radially from the nozzle portion 12 (in a direction perpendicular to the rotation axis of the nozzle portion 12). A locking portion 24 extends from the tip of the extension portion 22 to stop the movement of the trigger 7 when the linking arm 16 is in the locked position. In the illustrated example, as shown in FIG. 2, the locking portion 24 is disposed so as to be located on the lower surface T side of the linking arm 16 when the linking arm 16 is in the unlocked position. When the linkage arm 16 is rotated from the unlocked position to the locked position, as shown by the imaginary lines in FIG. 1(A), the locking portion 24 is inserted between the trigger 7 and the horizontal cylinder 4a, thereby locking the trigger 7. 2, the front view of the arm portion (radially protruding portion) of the linking arm 16 is formed in a V-shape with a base portion 16a extending upward and outward when in the unlocked position and a tip portion 16b that is horizontal when viewed from the front. A reinforcing rib 18 is formed on the top surface (top surface S) of the linking arm 16 when in the unlocked position, extending radially from the nozzle portion 12 to the base portion 16a. The reinforcing rib 18 does not necessarily have to be provided.

[0023] In the present invention, a sub-ground portion B is formed on the top surface S of the linking arm 16. In this specification, the term "top surface of the linking arm" includes the top surface of the extension portion 22. The auxiliary grounding portion B has a role of supporting the inverted posture of the dispenser main body 2 together with the main grounding portion A by being grounded to an external mounting surface M in the inverted state. Furthermore, by disposing the secondary grounding portion B on the top surface S of the linking arm 16, the linking arm 16 functions as a support rod for preventing the inverted dispenser main body 2 from falling over. In this specification, "supporting the inverted position of the dispenser main body together with the main grounding portion" is not necessarily limited to the case where the main grounding portion and the auxiliary grounding portion are in contact with the external mounting surface M at the same time. Whether or not both grounding portions are in contact with the ground at the same time depends on the shape (whether it is a completely flat surface or not) and properties (whether it is a hard surface or a soft surface, etc.) of the external placement surface M. The positional relationship between the main grounding portion A and the secondary grounding portion B needs to satisfy the following condition when viewed from the front (the direction of the rotation axis of the nozzle portion 12): "the main grounding portion and the secondary grounding portion are on approximately the same plane"; in other words, the secondary grounding portion B is positioned along the extension line e of the main grounding portion A shown in Figure 2. The term "along" includes both cases, as shown in Figure 2 and Figures 3(A) and 4(A) described below, where the sub-grounding portion B is located approximately on the extension line e, and also cases, not shown, where the sub-grounding portion B is located slightly away from the extension line e and in the vicinity of the extension line. The term "vicinity of the extension line e" may refer to either the lower side of the extension line e when the dispenser is in the upright position, or the upper side of the extension line e. In addition, in this embodiment, the sub-ground contact portion B is a ground contact surface portion having a certain extent (ground contact area), but it may be a point-like portion (ground contact point) instead of a ground contact surface portion. Also, in the illustrated example, when the linking arm 16 is moved to the unlocked position, the linking arm 16 does not exceed the extension line e in an inverted state, but the linking arm 16 may be designed to slightly exceed the extension line e.

[0024] In the above configuration, the trigger-type dispenser of the present invention is attached to the mouth and neck portion of the container body, and the contents can be ejected by rotating the linkage arm 16 90° from a vertical orientation to a horizontal orientation and then operating the trigger 7. When the contents have been used up and it is time to refill the contents, the linking arm 16 is set in a state in which it protrudes outward from the nozzle portion 12 as shown in FIG. 2(A), and in this state, the attachment cap 3 is removed from the mouth and neck portion of the container body, and the trigger-type dispenser is turned upside down and placed on the external mounting surface M. At this time, the stability of the inverted trigger-type dispenser can be improved by the main grounding portion A of the dispenser body 2 and the sub-grounding portion B of the linking arm 16. Therefore, the refilling work can be continued without worrying about the inverted dispenser body 2 tipping over. Next, the previously prepared refill container is removed, the inverted trigger dispenser is picked up again, returned to the upright position, and the attached cap is fitted onto the mouth and neck of the new container, completing the refilling process.

[0025] As described above, even in an embodiment in which the secondary grounding portion B is slightly away from and in the vicinity of the extension line e, when the inverted dispenser body 2 is placed on a soft support surface M such as a carpet, the deformation of the support surface M causes the main grounding portion A and the secondary grounding portion B to simultaneously contact the support surface M.

[0026] Other embodiments of the present invention will be described below. In these descriptions, explanations of structures that are the same as those in the first embodiment will be omitted.

[0027] Fig. 3 shows a trigger-type dispenser according to a second embodiment of the present invention. In this embodiment, as shown in Fig. 3(A), when the linking arm 16 is deployed in an unlocked state, the end face (upper face) of the reinforcing rib 18 is positioned on the same horizontal plane as the main ground contact part A, thereby forming the end face as the sub-ground contact part B. In this embodiment, the main ground portion A and the sub ground portion B are disposed flush with each other. According to this configuration, the stiffness of the linking arm 16 is increased by providing the reinforcing rib 18, and by making the end face of the linking arm 16 the secondary grounding portion B, the area that contacts the flat mounting surface M simultaneously with the primary grounding portion A in the inverted state shown in Fig. 4(B) is expanded in the protruding direction of the linking arm 16. Therefore, the stability of the dispenser main body 2 in the inverted position can be improved, and the resistance to an external force that tends to tip the dispenser over can be increased. In addition, the reinforcing rib 18 in the illustrated example is formed over the entire length of the linking arm 16. However, the length and installation range of the reinforcing rib 18 can be changed as appropriate.

[0028] Fig. 4 shows a trigger-type dispenser according to a third embodiment of the present invention. In this embodiment, as shown in Fig. 4(A), when the link arm 16 is deployed in the unlocked state, an auxiliary rib 20 is protruded from the top surface S of the link arm 16 at the tip side of the link arm 16. The end face (upper face) of the auxiliary rib 20 serves as a secondary ground contact portion B. Moreover, the main ground portion A and the sub ground portion B are disposed flush with each other. According to this configuration, by making the end face of the auxiliary rib 20 arranged on the tip side of the connecting arm 16 into the secondary grounding portion B, as shown in Figure 4 (B), the rattling of the dispenser placed inverted on the mounting surface M can be effectively suppressed, providing a more stable inverted state. The auxiliary rib 20 in the illustrated example is a horizontal rib that extends linearly in a direction perpendicular to the longitudinal direction of the linking arm 16. However, the direction and shape of the auxiliary rib 20 can be changed as appropriate. [Explanation of symbols]
