Description

[Technical Field]

[0001] The present invention relates to a discharge container, and more particularly to a container that discharges by pressing down a nozzle portion by operating a lever. [Background technology]

[0002] A known discharge container is equipped with an attachment cap fitted onto the mouth and neck of the container body, a nozzle portion connected to the container body and supported above the attachment cap in an upwardly biased state so that it can move up and down, and a lever protruding so as to be movable up and down from a support portion erected from the rear side of the attachment cap and linked to the nozzle portion, with a movable stopper interposed between the base half of the lever and the support portion (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2005-211855 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, a lever is added to the discharge container that raises and lowers the nozzle to discharge, making it easier to hold, press, and prevent slipping. However, it is difficult to assemble the overcap that covers the nozzle and the stopper that restricts depression, making it unsuitable for carrying and storing.

[0005] An object of the present invention is to provide a discharge container that has a lever and a liftable nozzle portion and is suitable for carrying and storing. [Means for solving the problem]

[0006] The first means comprises a container body 2 that stands up a mouth and neck portion 6, a dispenser (10) in which a nozzle part (40) is supported above an attachment cap (12) fitted onto the mouth and neck part (6) so as to be able to move up and down, and in which the nozzle part (40) is linked to a lever (46) which protrudes forward from a support part (30) arranged behind the nozzle part (40) so as to be able to swing up and down; a cover body (60) that also serves as a stopper and is detachably disposed around the nozzle portion (40) and is interposed between the lever (46) and the nozzle portion (40), This cover body 60 is fixed to the top surface 20 of the mounting cap 12 so that it cannot move laterally, and is configured to restrict the swinging of the lever 46 when the lever is operated to lock it by sandwiching a restraining portion C, which is part of the cover body 60, between the tip half 46B of the lever 46 and the mounting cap 12.

[0007] In this means, as shown in Figure 1, in a discharge container in which a nozzle part 40 supported above the attachment cap 12 so as to be able to move up and down is linked in a manner that allows it to be interlocked with a lever 46 that protrudes forward from the support part 30 so as to be able to swing up and down, a cover body 60 that also serves as a stopper is arranged around the nozzle part 40, interposed between the lever 46 and the nozzle part 40. According to this structure, the cover body 60 interposed between the lever 46 and the nozzle portion 40 also serves as a stopper, making it suitable for easy transport and storage. In addition, the cover body 60 is fixed to the top surface 20 of the mounting cap 12 so that it cannot move laterally, and when the lever is operated to lock it, the restraining portion C of the cover body 60 is sandwiched between the tip half portion 46B of the lever 46 and the mounting cap 12, thereby restricting the swinging of the lever 46. According to this structure, the act of attaching and detaching the cover body 60 to and from the dispenser 10 also serves as an on / off operation for the lock, making it easy to use.

[0008] the second means includes the first means, and the cover body 60 has a head portion 62 that covers the nozzle portion 40, and a main leg piece 68 that is the restraining portion C is suspended from the front side of the head portion 62; An engaging protrusion 24 is formed on the top surface 20 of the mounting cap 12 in close proximity to the rear surface of the main leg piece 68, and a pressing portion 58 is formed on the front half 46B of the lever 46 in close proximity to the front surface of the main leg piece 68. When an attempt is made to operate the lever for locking, the main leg piece 68 is pinched between the engaging protrusion 24 and the pressing portion 58, thereby restricting the swing of the lever 46.

[0009] 1, in this means, a main landing gear piece 68 is suspended from the front side of the head 62 of the cover body 60. The main landing gear piece 68 is then sandwiched between the engaging protrusion 24 of the mounting cap 12 and the pressing portion 58 of the lever 46, thereby realizing the locking function. With this structure, the lock can be turned off by pinching and pulling up the head 62 of the cover body 60, and the lock can be turned on by inserting the cover body 60 around the nozzle part 40 while still pinching the head 62. This is therefore no different from the normal process of attaching and detaching the cover body 60, making it easier to use.

[0010] The third means includes the first means or the second means, and a secondary leg piece 76 is suspended from the rear side of the head 62, An insertion opening 52 for inserting the nozzle portion 40 and the cover body 60 is opened on the upper surface of the base half portion 46A of the lever 46, The cover body 60 is inserted between the lever 46 and the nozzle portion 40 from above through the insertion opening 52, and is formed so as to be able to be inserted into a fixed position where the main leg piece 68 is sandwiched between the engaging protrusion 24 and the pressing portion 58, A guide surface portion 34 is formed on the front side of the support portion 30, which slides against the auxiliary leg piece 76 when the cover body 60 is inserted, thereby guiding the cover body 60 to the fixed position.

[0011] 1, this means has a guide surface portion 34 on the front side of the support portion 30. When the cover body 60 is inserted through the insertion opening 52 as shown in FIG. 6(A), this guide surface portion 34 comes into sliding contact with the auxiliary leg piece 76 (see FIG. 6(B)), and guides the cover body 60 to a fixed position. According to this structure, by simply grasping the head 62 of the cover body 60 and inserting it around the nozzle portion 40, the cover body 60 can be guided to a fixed position where it is locked, which is easy to use.

[0012] The fourth means has any one of the first to third means, and the guide surface portion 34 is an inclined surface that slopes from the upper rear side to the lower front side, and the auxiliary leg piece 76 slides along this inclined surface, so that the cover body 60 inserted into the insertion opening 52 in an upright position tilts backward from the upright position.

[0013] In this means, as shown in Figure 4(C), the guide surface portion 34 is an inclined surface that slopes from the upper rear side to the lower front side, and the sub-leg piece 76 slides along this inclined surface, so that the cover body 60 inserted in an upright position is tilted backward as shown in Figure 6(C). According to this structure, the main leg piece 68 can be smoothly guided between the pressing portion 58 and the engaging protrusion 24 by controlling the attitude of the cover body 60 .

[0014] The fifth means includes any one of the first means to the fourth means, and a secondary leg piece 76 is suspended from the rear side of the head 62. An insertion opening 52 for inserting the nozzle portion 40 and the cover body 60 is opened on the upper surface of the base half portion 46A of the lever 46, A downward engaging step 56 is formed near the rear edge 55 of the insertion opening 52, and a retaining protrusion 80 is formed on the rear surface of the auxiliary leg piece 76 so as to climb over the rear edge 55 of the insertion opening 52 and engage with the engaging step 56 when the cover body 60 is inserted into the insertion opening 52 from above.

[0015] In this means, as shown in FIG. 1, a downward engaging step 56 is formed on the rear edge 55 of the insertion opening 52, and a retaining projection 80 that engages with the engaging step 56 is formed on the rear surface of the secondary leg piece 76. This structure can prevent the cover body 60 from accidentally slipping out upward. [Effects of the Invention]

[0016] According to the present invention, a container that ejects liquid by pressing down a nozzle portion by operating a lever can be easily carried and stored. [Brief explanation of the drawings]

BEST MODE FOR CARRYING OUT THE INVENTION

[0018] 1 to 6 show a discharge container according to an embodiment of the present invention. This discharge container comprises a container body 2, a dispenser 10, and a cover body 60. These members can be made of, for example, synthetic resin material or metal. The dispenser of this embodiment is a nasal spray container, but the structure thereof can be modified as appropriate.

[0019] The container body 2 has a mouth / neck portion 6 that stands up from the body portion 4. A male thread portion 8 is formed on the outer surface of this mouth / neck portion. In the illustrated example, the upper end of the mouth / neck portion 6 abuts against the lower surface of an inward flange 18, which will be described later, via a packing. However, these structures can be modified as appropriate.

[0020] As shown in FIG. 1, the dispenser 10 includes a mounting member 11, a cylinder 36, a nozzle portion 40, and a lever 46. The dispenser 10 has a cylinder 36 suspended within the container body 2 via an attachment member 11, a nozzle portion 40 attached to a stem 38 (see Figure 2) of an actuating member arranged in the cylinder so that it can be raised and lowered in an upwardly biased state, and is configured so that the contents are dispensed from the nozzle portion 40 by operating a lever 46 attached to the attachment member 11.

[0021] The mounting member 11 is a member that serves to mount the cylinder 36 and the lever 46 on the container body 2, and includes a mounting cap 12 and a support portion 30, as shown in FIG. 4(C). In the illustrated example, the support portion 30 is integrally connected to the rear portion of the mounting cap 12, but this structure can be modified as appropriate. In this specification, for the purpose of explaining the configuration, the right side of FIG. 1 will be referred to as the "rear", the left side as the "front", and the directions perpendicular to the paper surface as the "left and right".

[0022] The attachment cap 12 is fitted onto the mouth / neck portion 6, and has a communication port 13 for communicating the nozzle portion 40 with the inside of the container body 2 (see FIG. 2). In this embodiment, the attachment cap 12 is configured by providing a guide tube 21 standing on the upper end of an attachment tube 14 fitted to the outer surface of the mouth / neck portion 6 via an inward flange 18 (see FIG. 4(C)). The communication port 13 is opened at the upper end of this guide tube 21. The mounting cylinder 14 has an internal thread 16 formed on its inner surface, which is engaged with the external thread 8 . The guide tube 21 in the illustrated example has a small diameter cylindrical portion 23 standing upright via a circumferential step b from a large diameter cylindrical portion 22 connected to the inward flange 18. However, these structures can be modified as appropriate.

[0023] In this embodiment, an engaging protrusion 24 for engaging (hooking) a main leg piece 68 (described later) is provided on the top surface 20 of the mounting cap (the upper surface of the inward flange 18 in the illustrated example). This latch prevents the cover body 60 from shifting sideways backward when the lever 46 is pulled downward and backward as shown by the arrow in FIG. 6(D). This engaging protrusion 24 is disposed on the front side (opposite side from the support portion 30) of the guide tube 21. In the illustrated example, the engaging protrusion 24 is connected to the large diameter cylindrical portion 22 of the guide tube 21, but the structure can be modified as appropriate. In the state shown in FIG. 1 before the lever is operated, the engaging protrusion 24 is in close proximity to (including abutting against) the rear surface of the main landing gear piece 68. In this embodiment, the engaging protrusion 24 is defined by a guide surface 25 formed from above toward the front, and a pair of side surfaces 28 formed in the left-right direction (lateral direction). 4(C), the guide surface 25 is an inclined surface from the upper rear side to the lower front side when viewed from the left-right direction, and the upper part of the guide surface 25 is formed as a gentle slope portion 26, and the lower part of the guide surface 25 is formed as a steep slope portion 27. However, these shapes can be changed as appropriate.

[0024] The support portion 30 stands upright from the rear of the mounting cap 12 so as to be disposed behind the nozzle portion 40 . As shown in FIG. 4(C), a pivot shaft 32 for pivotally mounting a lever 46 is formed on the upper portion of the support portion 30. As shown in Figure 4(A), the support portion 30 in the illustrated example has a pair of support plates 31 that are identical when viewed from the left and right, and a pair of pivot shafts 32 protrude outward in the left and right direction from the top of these support plates 31.

[0025] A guide surface portion 34 is formed on the front surface of the support portion 30 for sliding contact with a sub-leg piece 76 described below. The guide surface portion 34 is a portion for guiding the cover body 60 to a fixed position (described later) in a rearward tilted posture shown in FIG. 6(C) when the cover body 60 is arranged around the nozzle portion 40. In this embodiment, the guide surface portion 34 is an inclined surface from the upper rear side to the lower front side when viewed from the left-right direction. The term "inclined surface" includes the concepts of both a curved inclined surface and a flat inclined surface. The guide surface portion 34 in this embodiment is a curved inclined surface formed so as to have a steeper slope toward the lower front side (approaching a vertical line in the illustrated example). However, the shape of the guide surface portion 34 can be changed as appropriate. In the illustrated example, the guide surface portion 34 is formed by the front surfaces of a pair of identical left and right support plates 31. This structure can be modified as appropriate.

[0026] The cylinder 36 is disposed inside the container body 2 via a mounting member 11 . The lower half of an actuating member (not shown) is inserted inside the cylinder. A coil spring (not shown) is interposed between this lower half and the bottom of the cylinder 36. When the actuating member is raised and lowered, the liquid in the container body 2 is sucked into the cylinder 36 and then discharged from the stem 38 of the actuating member that protrudes upward from the guide tube 21.

[0027] The nozzle portion 40 is connected to the upper end of the stem 38 and is supported above the mounting cap 12 so as to be able to move up and down while being biased upward. In the illustrated example, a nozzle hole 42 is opened at the top of the nozzle portion 40 . The nozzle portion 40 incorporates an element (not shown) having a spray flow path (groove) for spraying the content liquid from the nozzle hole 42. A pair of left and right linking portions 44 are attached to the side surfaces of the nozzle portion 40 . The nozzle portion 40 in the illustrated example is formed in a tapered column shape with a small diameter at the tip.

[0028] The lever 46 is a member pivotally attached to the support portion 30 so as to be movable up and down, and projects forward from the support portion 30 through the vicinity of the nozzle portion 40 . As shown in Figure 5(A), the lever 46 in the illustrated example is formed in a "U" shape consisting of a base half 46A and a tip half 46B, and is formed by connecting the upper ends of a pair of left and right side end plates 47 with an upper plate 50.

[0029] The base half 46A has a shaft hole 48, an insertion opening 52, and a connecting recess 49 formed therein. The shaft holes 48 are respectively disposed at the rear of the pair of side end plates 47 so as to fit the pair of pivot shafts 32 therein. The insertion opening 52 is opened in the upper plate 50 at a position forward of the shaft hole 48, and has a size that allows the nozzle portion 40 and the cover body 60 to be inserted therethrough. As shown in FIG. 5B, the insertion opening 52 in the illustrated example is formed in a generally rectangular shape that is long in the front-rear direction, and is defined by a front edge 53, a pair of left and right side edges 54, and a rear edge 55. The front edge 53 is formed in a curved shape that convex forward to correspond to the front plate 66 of the cover body 60 described later, and the rear edge 55 is formed in a straight line in the left-right direction to correspond to the rear plate 74 of the cover body 60 described later. The base half 46A is formed with a downward engaging step 56 located near the rear edge 55 on the rear side of the upper plate 50 for engaging with a retaining projection 80, which will be described later. The engaging step 56 in the illustrated example extends in the left-right direction along the rear edge 55. Further, positioned below the insertion opening 52, a downwardly opening linking recess 49 into which the linking portion 44 is inserted is formed on the inner surface of the pair of side end plates 47.

[0030] The front half portion 46B is formed with a pressing portion 58 for pressing against the front surface of a main leg piece 68 of a cover body 60 (to be described later) when the lever is operated. In the state before the lever is operated (the state shown in FIG. 1), the pressing portion 58 is in close proximity to (including abutting against) the front surface of the main leg piece 68. It is desirable that the pressing portion 58 abuts (fits) against the main leg piece 68 over a certain area so that the main leg piece 68 is stably sandwiched between the pressing portion 58 and the engaging protrusion 24. The pressing portion 58 in the illustrated example is formed as a vertical (flat) pressing plate portion connected to the pair of side end plates 47. As shown in FIG. 1, a gap h is provided between the lower end surface of the pressing portion 58 and the upper surface of the engaging protrusion 24, and this gap serves as an insertion margin so that the main leg piece 68 can be inserted and clamped between the pressing portion 58 and the engaging protrusion 24. The pressing portion 58 in the illustrated example is disposed adjacent to the front edge 53 of the insertion opening 52 . However, the shape and arrangement of the pressing portion 58 can be changed as appropriate.

[0031] The cover body 60 serves both as a cover that covers at least the nozzle hole 42 of the nozzle portion 40 and as a stopper that restricts the lever operation. The cover body 60 is a member that is elongated as a whole along the longitudinal direction of the nozzle portion 40, and is disposed around the nozzle portion 40 from above so as to be detachable. In addition, the cover body 60 is interposed between the lever 46 and the nozzle portion 40, and in this embodiment, is assembled to the dispenser 10 so as to be inserted into the gap between the periphery of the insertion port 52 of the lever 46 and the nozzle portion 40. The cover body 60 has a stopper C for stopping the swing of the lever 46 when the user operates the lever in the locked state. The stopper C has enough rigidity to maintain the locked state of the lever. In this embodiment, the cover body 60 has a head portion 62 shown surrounded by a dashed line in Figure 3 (B), a main leg piece 68 hanging down from the front side of the head portion 62, and a sub-leg piece 76 hanging down from the rear side of the head portion 62. The main leg piece 68, as the aforementioned restraining portion C, is sandwiched between the pressing portion 58 and the engaging protrusion 24, thereby restricting the swinging of the lever 46.

[0032] The head portion 62 serves as a cover body (cap) that covers the nozzle portion 40, and is disposed above the insertion opening 52 of the lever 46 as shown in FIG. The head 62 in the illustrated example is in the shape of a cylindrical cap with a top, and as shown in Figure 3(A), when viewed from the front, it consists of a pair of side wall portions 86 extending in a V-shape from the side edges of the horizontal top plate 64, a front wall portion 67 continuous with the front ends of these side wall portions 86, and a rear wall portion 75 continuous with the rear ends of the side wall portions 86. 3B, the main leg piece 68 extends downward from the lower end m of the front wall portion 67, and the sub-leg piece 76 extends downward from the lower end n of the rear wall portion 75 to the vicinity of the top surface 20 of the mounting cap 12. The lower end e of the main leg piece 68 abuts against the guide surface 25 of the engaging protrusion 24, and the sub-leg piece 76 abuts against the support part 30, thereby fixing the cover body 60 so that it does not move sideways backward from the position shown in Figure 1. The upper portion of the main leg piece 68 is pressed against the pressing portion 58, and the lower end e of the main leg piece 68 is pressed against the engaging protrusion 24, so that the main leg piece 68 is sandwiched between the pressing portion 58 and the engaging protrusion 24, and the lever operation is locked. Furthermore, a retaining projection 80 that engages with the engaging step 56 is provided on the upper rear surface of the secondary leg piece 76, thereby preventing the cover body 60 from being released from the locked state due to an unexpected upward slippage. The retaining projection 80 in the illustrated example is formed over the entire width of the secondary leg piece 76, as shown in Figure 3(C). As shown in Figures 6(B) and 6(C), the lower end g of the auxiliary leg piece 76 slides along the guide surface 34 of the support part 30 during the insertion process of the cover body 60. Because this guide surface 34 is an inclined surface from the upper rear side to the lower front side, the sliding causes a forward stress to act from the guide surface 34 on the auxiliary leg piece 76, causing the cover body 60 to tilt backward. Because the cover body 60 descends in a rearward tilted position, controlling this position makes it possible to optimize the angle at which the main leg piece 68 is inserted into the gap h between the pressing portion 58 and the engaging protrusion 24. Therefore, the main leg piece 68 can pass through the gap h without difficulty, and the lower end e of the main leg piece 68 slides along the guide surface 25 and comes into contact with the steep slope portion 27. If the lower end g of the secondary leg piece 76 is not brought into sliding contact with the guide surface portion 34, the lower end e of the main leg piece 68 may come into contact with, for example, the circumferential step b of the guide tube 21, depending on the position of the cover body 60. The configuration of this embodiment avoids such a problem and makes it possible to easily and reliably guide the cover body 60 to the fixed position shown in FIG. Here, "fixed position" means the position where the cover body locks the lever operation, and in the illustrated example, it means the position where the main leg piece is sandwiched between the pressing portion and the engaging protrusion.

[0033] In the illustrated example, as shown in FIG. 3(B), the front wall portion 67 and the main leg piece 68 are formed as a single plate member (front plate 66) that protrudes from the front end of the top plate 64. Here, if a line passing through the center of the top plate 64 in the molded state and extending in the normal direction is referred to as a main axis A, the front plate 66 is provided so as to protrude downward and away from the main axis A. 1, a gap s is provided between the front plate 66 and the nozzle portion 40. This gap s is maintained even when the lever 46 is pulled during locking, and is designed so that part of the pulling force is not transmitted to the nozzle portion 40. The front plate 66 is a curved plate (gutter-shaped plate) having a forward-convex arc-shaped cross section over its entire length from the upper end d to the lower end e, and both the outer and inner surfaces are rounded. This shape gives the front plate 66 greater rigidity than a flat plate. The width w1 of the main leg piece 68 shown in Fig. 3(A) is larger than the width w2 of the engaging protrusion 24 shown in Fig. 4(B). This allows the engaging protrusion 24 to be embraced (held) inside the main leg piece 68, which has an arc-shaped cross section. Therefore, the main leg piece 68 can be stably sandwiched between the pressing portion 58 and the engaging protrusion 24. However, these structures can be modified as appropriate. Therefore, when the lever 46 is pulled from the state shown in FIG. 1 in which the main leg piece 68 is sandwiched between the pressing portion 58 and the engaging protrusion 24, as shown in FIG. 6(D), the main leg piece 68 can sufficiently resist the pulling force. 3(B), the rear portion of the lower end e of the main leg piece 68 is formed into a rounded chamfered portion 70 when viewed from the left and right. This chamfered portion 70 is provided so as to allow smooth sliding from the gentle slope portion 26 to the steep slope portion 27 of the guide surface 25 during the process of setting the cover body 60 in place (see FIG. 6(C)).

[0034] In the illustrated example, as shown in FIG. 3(B), the rear wall portion 75 and the auxiliary leg piece 76 are formed as a single plate member (rear plate 74) that protrudes from the rear end of the top plate 64. However, the rear plate 74 is inclined downward from the upper end f to point i so as to move away from the main axis A rearward, and extends almost vertically from point i to the lower end g. The thickness of the rear plate 74 is designed to be constant from the upper end f to point i, increase downward from point i to point j, and decrease downward from point j to the lower end g. The portion (vertical surface portion) 82 below point i on the front surface of the rear plate 74 has a vertical straight shape. As shown in Figure 1, the lower part of the vertical surface portion 82 is close to or abuts against the rear surface of the large-diameter cylindrical portion 22 of the guide cylinder 21. This prevents the retaining projection 80 from accidentally coming off the engaging step portion 56. The upper half of the rear surface of the rear plate 74 (the portion above point j) is formed in a straight shape that slopes downward and rearward, and the lower half of the rear surface (the portion below point j) is formed in a straight shape that slopes downward and forward. The lower half of the rear surface of the rear plate 74 is referred to as a sliding surface portion 84. Along the upper end of this sliding surface portion 84, the retaining projection 80 is disposed. When the cover body 60 is inserted into the insertion opening 52, the sliding surface portion 84 is pressed against the rear edge 55 of the insertion opening 52 (see Figure 6(B)), and by sliding over the rear edge 55 (see Figure 6(C)), the anti-pullout protrusion 80 engages with the engagement step portion 56. In parallel with this process, the sliding surface portion 84 slides along the guide surface portion 34 near the lower end g of the secondary leg piece 76 (FIGS. 6(B) to 6(D)).

[0035] 1, the cover body 60 is interposed in the space between the lever 46 and the nozzle portion 40 (the gap between the periphery of the insertion opening 52 and the nozzle portion 40), and the main leg piece 68 of the cover body 60 is sandwiched as a restraining portion C between the pressing portion 58 of the lever 46 and the engaging protrusion 24 of the attachment cap 12, thereby locking the lever operation. Therefore, in this locked state, even if an attempt is made to pull the lever 46, the lever 46 will not move, as shown in FIG. 6(D). For example, in the container of Patent Document 1, which has a movable stopper interposed between the support part and the lever base half, when stored in a bag or the like, the stopper may come into contact with other stored items and become unlocked, but the cover body 60 of the present invention will not be unlocked unless it is intentionally pulled out of the insertion opening, which is preferable because the lock will not be released unexpectedly during transportation or storage. The cover body 60 is fixed to the top surface 20 of the mounting cap 12 so that it cannot move sideways rearward, with the main leg piece 68 abutting against the engaging protrusion 24 and the sub-leg piece 76 abutting against the support part 30. Therefore, the cover body 60 can sufficiently withstand the pulling force of the lever operation when locked. When the cover body 60 is removed from the state shown in FIG. 1, the lever operation is unlocked, and when the lever 46 is pulled, the contents are sprayed from the nozzle hole 42 of the nozzle portion 40. When spraying is completed, insert the cover body 60 into the insertion opening 52 from above and set it in the fixed position where the main leg piece 68 is sandwiched between the pressing portion 58 and the engaging protrusion 24, and the lever operation is locked again. In this operation, as shown in FIG. 6(A), when the cover body 60 is inserted into the insertion opening 52 in an upright position with the main axis A vertical, the lower end g of the secondary leg piece 76 comes into contact with and slides against the guide surface portion 34 of the support portion 30, as shown in FIG. 6(B), causing the cover body 60 to assume a rearward tilted position as shown by the solid line in FIG. 6(C), and in this state the main leg piece 68 is smoothly inserted into the gap h between the pressing portion 58 and the engaging protrusion 24. As a result, the guide surface portion 34 guides the cover body 60 to a fixed position, so that the user can simply lower the cover body 60 through the insertion opening 52 to properly set the cover body 60, which is easy to use.

[0036] According to the above-described configuration and action, since it is interposed between the lever 46 and the nozzle portion 40, it is convenient for carrying and storing, and since the cover body 60 also serves as a stopper, the act of covering the nozzle portion 40 with the cover body 60 can also serve as a locking operation. The secondary leg piece 76 of the cover body 60 slides against the guide surface portion 34, automatically guiding the cover body to a fixed position where the lever operation is locked, making it easy to use, and since the cover body 60 tilts backward during this sliding contact process, the main leg piece 68 can be smoothly guided to a position (gap h between the pressing portion 58 and the engaging protrusion 24) where it can perform its locking function. Furthermore, by engaging the retaining projection 80 of the cover body 60 with the engagement step 56 of the lever 46, the cover body 60 can be prevented from accidentally coming off upward.
