[Figure 8] A side view of the push bottle when refilling. DETAILED DESCRIPTION OF THE INVENTION

[0009] A push bottle 1 according to one embodiment of the present invention will be described with reference to the drawings.

[0010] As shown in Figure 1, push bottle 1 has container 2 for containing a fluid such as detergent, pump 3 formed integrally with cap 31 that seals mouth 21 of container 2 and sucks up the fluid inside container 2, and push kit 5 attached to cap 31. The fluid contained in container 2 is not particularly limited as long as it can be sucked up and discharged by pump 3, but may be, for example, laundry detergent, fabric softener, shampoo, liquid soap, dish detergent, etc.

[0011] In this specification, with the push bottle 1 in an upright position as the reference, the longitudinal direction of the container 2 of the push bottle 1 is the "up-down direction," the direction in which fluid is discharged from the push bottle 1 is the "front," and the opposite direction is the "rear," and the direction perpendicular to the "up-down direction" and "front-rear direction" is the "width direction (left-right direction)." The left-right direction is based on the left and right of the user when holding the handle 62.

[0012] 1, the container 2 has a generally cylindrical shape and includes a mouth 21 that opens at the top end, a bottom 22 located at the bottom end, and a peripheral wall 23 that connects the mouth 21 and the bottom 22. In this embodiment, the diameter of the container 2 increases from the mouth 21 toward the bottom 22 (downward). The container 2 is made of, for example, resin.

[0013] 1 and 2, in this embodiment, the height L of the container 2 is set to 225 mm, and the diameter D of the bottom 22 is set to 75 mm. Because the height L and diameter D of the container 2 are appropriately set, problems with storage, such as difficulty in storage due to the height L and diameter D, and problems with stability, such as the push bottle 1 tipping over due to the height L being too large compared to the diameter D, can be prevented.

[0014] As shown in Figure 1, a refill line L1 is marked on the container 2 at a predetermined height to guide refilling. This allows the container to be easily refilled with an appropriate flow rate. For example, the position of the refill line L1 is the position where, when refilling the container 2 with fluid, the amount of fluid in the container 2 becomes 400 mL.

[0015] The pump 3 may be a pump used in a general pump dispenser that discharges the fluid in the container 2 from the nozzle 35 by the up and down movement of the pressing part 34. The configuration of the pump 3 is simply shown in Figure 1, and detailed description will be omitted.

[0016] The pump 3 includes a cap 31 that can be attached to the mouth portion 21, a cylinder 32 that can be attached to the cap 31, a piston (movable portion) 33 that is slidably housed within the cylinder 32, a pressing portion 34 connected to the upper end of the piston 33, a nozzle 35 provided in front of the pressing portion 34, and an elastic member 36 that biases the piston 33 toward a first position P1 (shown by solid lines in FIGS. 1 to 3 ) in which the piston 33 is positioned upward. The piston 33 and the pressing portion 34 are movable between the first position P1 and a second position P2 (shown by two-dot chain lines in FIG. 3 ) in which the piston 33 is positioned downward. The cap 31 can be attached to the mouth portion 21, for example, by being screwed onto the mouth portion 21. The outer peripheral surface of the cap 31 is provided with serrations extending in the vertical direction. As shown in FIGS. 1 and 2 , the mouth portion 21, the cap 31, the piston 33, and the pressing portion 34 are attached so that their center lines C are generally aligned.

[0017] As shown in Fig. 1, a tubular member 37 for sucking up fluid in the container 2 is attached below the pump 3. The tubular member 37 has a first portion 38 connected to the pump 3 and extending in the vertical direction, a second portion 39 at least a portion of which is located in the bottom portion 22, and a connecting member 40 connecting the first portion 38 and the second portion 39.

[0018] The first portion 38 has an upper end 38a connected to the pump 3 and a lower end 38b connected to the top of the connecting member 40. The second portion 39 has an upper end 39a connected to the bottom of the connecting member 40 and a lower end 39b opening into the bottom corner 24 formed by the bottom 22 and the peripheral wall 23 of the container 2. In this embodiment, the first portion 38 and the second portion 39 are made of resin, which has high rigidity and does not flexibly deform like a rubber hose or the like.

[0019] The connecting member 40 has an upper portion 41 to which the lower end portion 38b of the first portion 38 is connected, a lower portion 42 to which the upper end portion 39a of the second portion 39 is connected, and a bending portion 43 that bends the lower portion 42 relative to the upper portion 41. In this embodiment, the connecting member 40 is made of resin.

[0020] The upper portion 41 is hollow cylindrical and extends in the vertical direction. The first portion 38 is fitted to the outer periphery of the upper portion 41. The lower portion 42 is hollow cylindrical and inclined downward toward the radially outward direction of the container 2 (in the direction away from the center line C of the container 2). The second portion 39 is fitted to the inner periphery of the lower portion 42. As a result, the connecting member 40 causes the second portion 39 to incline downward toward the radially outward direction.

[0021] In this embodiment, with the second portion 39 disposed at an angle relative to the vertical direction, the lower end 39b is cut in the vertical and horizontal directions to follow the shapes of the bottom 22 and the peripheral wall 23. This makes it easier to position the lower end 39b along the bottom corner 24 formed by the bottom 22 and the peripheral wall 23. In this embodiment, the lower end 39b is positioned near the bottom corner 24, and, for example, the distance S2 of the lower end 39b from the peripheral wall 23 and / or the distance S3 of the lower end 39b from the bottom 22 is set to be 1 mm or more and 5 mm or less.

[0022] As shown in FIG. 1, the push kit 5 has a base 6 fixed to a cap 31, and a lever 7 supported by the base 6 so as to be rotatable about a hinge axis 7a.

[0023] As shown in Figures 2 and 3, the base 6 has a cylindrical peripheral wall portion 61 that is fitted to the outer peripheral surface of the cap 31, a handle 62 that is continuous with the peripheral wall portion 61 and extends rearward, and a pair of left and right side wall portions 63 that extend upward from the peripheral wall portion 61.

[0024] The peripheral wall portion 61 has a serration portion 61b that is provided on the inner peripheral surface 61a and extends in the vertical direction, and a protrusion 61c that protrudes from the inner peripheral surface 61a at the lower end.

[0025] The serration portion 61b is adapted to engage with serrations provided on the outer peripheral surface of the cap 31 as a circumferential rotation prevention device when the base 6 is attached to the cap 31. The base 6 and the cap 31 may be attached by press-fitting or the like. The protrusion 61c is located below the lower end of the cap 31 and extends radially inward. The protrusion 61c prevents the base 6 from slipping out of the cap 31 from above.

[0026] As shown in FIG. 3, the handle 62 extends rearward from the rear side of the upper end of the peripheral wall 61 in a direction sloping downward toward the rear. The handle 62 has a curved portion 62a that curves rearward and downward from the peripheral wall 61, a main body portion 62b that extends rearward from the lower end of the curved portion 62a, and a pair of handle-side walls 62c that extend upward from both left and right edges of the curved portion 62a and the main body portion 62b. A gap S1 between the main body portion 62b and the container 2 or the peripheral wall 61 increases downward. For example, a user can insert fingers other than the thumb from below between the handle 62 and the container 2 to grip the handle 62.

[0027] In this embodiment, the handle angle α, which is the angle between the handle 62 and the peripheral wall portion 61, is preferably 15 degrees or more and 45 degrees or less, and is set to 25 degrees in this embodiment. More specifically, the handle angle α is the angle between the peripheral wall portion 61 facing the main body portion 62b in the vertical cross section and the extending direction of the main body portion 62b.

[0028] As shown in FIGS. 3 and 4, the handle side wall 62c is smoothly connected to the curved portion 62a and the main body portion 62b. In this embodiment, the handle side wall 62c and the main body portion 62b have the same center of curvature O1 in the cross section in FIG. 4. The center of curvature O1 is located above the handle 62. In other words, the handle 62 has a curved shape that is convex downward in a cross section perpendicular to the main body portion 62b. In this embodiment, the length L2 along the extension direction of the handle side wall 62c and the main body portion 62b in the cross section perpendicular to the surface is set to 13.5 mm. In this embodiment, the radius of curvature R1 of the handle 62 is the radius of curvature of the main body portion 62b and is set to 12.5 mm.

[0029] 2, the side wall portions 63 are disposed at intervals in the left-right direction. The side wall portion 63 has a front wall portion 63a that protrudes forward beyond the peripheral wall portion 61, and a rear wall portion 63b that extends upward from the upper end of the peripheral wall portion 61 and connects to the handle-side wall portion 62c. The rear wall portion 63b is located to the side of the pressing portion 34, and the front wall portion 63a is located forward of the pressing portion 34.

[0030] The distance between the pair of left and right side wall portions 63 narrows from the rear wall portion 63b to the front wall portion 63a. The distance between the front wall portion 63a is set wider than the width of the nozzle 35. The distance between the rear wall portion 63b is set wider than the width of the pressing portion 34. The front wall portion 63a and the rear wall portion 63b cover the piston 33, the pressing portion 34, and the nozzle 35 from the sides.

[0031] FIG. 5 shows a front view of the base 6. As shown in FIG. 5, the base 6 has a base vertical wall portion 63d extending inward in the width direction from the tip of the front wall portion 63a. The base 6 has a base opening 64 formed by an inner edge portion 63e of the base vertical wall portion 63d and an upper edge portion 61d of the peripheral wall portion 61. The base opening 64 is generally U-shaped in a front view. As shown in FIG. 3, the tip of the nozzle 35 penetrates the base opening 64 in the front-rear direction. The size of the base opening 64 is set so as not to interfere with the up-and-down movement of the nozzle 35 accompanying the movement of the piston 33 between a first position P1 indicated by a dashed line in FIG. 5 and a second position P2 indicated by a two-dot chain line in FIG. 5.

[0032] As shown in Figures 2 and 3, the front wall portion 63a has a hinge hole 63f for supporting the lever 7 so that it can rotate around the hinge axis 7a, and a first stopper portion 63d and a second stopper portion 63g that restrict the rotation of the lever 7.

[0033] 3, the hinge holes 63f are located at the lower end of the front wall portions 63a and are through-holes that pass through the pair of left and right front wall portions 63a in the width direction.

[0034] As shown in FIGS. 2 and 3, the first stopper portion 63d is formed by a base vertical wall portion 63d. When the piston 33 is located at the first position P1, a lever front wall 75 (described later) abuts against the first stopper portion 63d from the rear side. The second stopper portion 63g is located rearward of the hinge hole 63f and is a protrusion that protrudes inward in the width direction from the left and right front wall portions 63a and extends in the up-down direction. When the piston 33 is located at the first position P1, a lever step portion 74b (described later) abuts against the second stopper portion 63g from the rear side. The second stopper portion 63g is a base step that abuts against the lever step portion 74b. The first stopper portion 63d, the second stopper portion 63g, the lever front wall 75, and the lever step portion 74b are located above the stopper hole 63f, so that when the piston 33 moves from the second position P2 to the first position P1, the lever 7 is prevented from rotating forward when it attempts to rotate counterclockwise.

[0035] 2 and 3, the lever 7 is disposed so as to extend in the front-rear direction and cover the pressing portion 34 from above. The lever 7 has a hinge pin 71 rotatably supported on the base 6, and an operating piece 72 that is operated to rotate the lever 7 about a hinge axis 7a. The lever 7 extends from the hinge pin 71 in a direction opposite to the extension direction of the nozzle 35 (the discharge direction of the fluid discharged from the nozzle 35). The hinge axis 7a is disposed so as to extend in the left-right direction near the nozzle 35.

[0036] As shown in Figures 3 and 6, the lever 7 has a lever upper wall 73 extending forward from the operating piece 72, a pair of left and right lever vertical walls 74 extending downward from both widthwise edges of the lever upper wall 73, and a pair of left and right lever front walls 75 protruding inward in the widthwise direction from the front ends of the pair of left and right lever vertical walls 74, respectively.

[0037] 3, the lever upper wall 73 is inclined upward and rearward when the operating piece 72 is not being pressed. The lever upper wall 73 has an upper wall main body portion 73a provided at a position corresponding to the top of the pressing portion 34, and an inclined portion 73b inclined downward and forward from the front end of the upper wall main body portion 73a. The operating piece 72 extends rearward in a generally horizontal direction from the rear end of the upper wall main body portion 73a.

[0038] The upper wall main body portion 73a is inclined upward toward the rear with respect to the horizontal direction (front-to-rear direction), and the upper wall inclination angle α2 of the upper wall main body portion 73a with respect to the horizontal direction is smaller than the inclined portion angle α3 of the inclined portion 73b with respect to the horizontal direction; for example, the upper wall inclination angle α2 is set to 10.5 degrees, and the inclined portion angle α3 is set to 45 degrees. A bent portion 73c is formed between the upper wall main body portion 73a and the inclined portion 73b. Because the difference between the inclined portion angle α3 and the upper wall inclination angle α2 (the angle of the bent portion 73c) is appropriately set, the bending angle at the portion continuing from the operating piece 72, which is formed to extend generally horizontally, can be suppressed from the perspective of a pressing operation from above to below.

[0039] 2 and 7, the lever upper wall 73 has the widest left-right width above the pressing portion 34, and the left-right width narrows toward the front and rear of the pressing portion 34. The left-right width W1 of the upper wall main body portion 73a is larger than the left-right width W of the pressing portion 34, and is larger than the left-right width W2 of the inclined portion 73b and the left-right width W3 of the operating piece 72. More specifically, the left-right width W1 of the upper wall main body portion 73a is preferably set to 10 mm or more, and is set to 36 mm in this embodiment.

[0040] 2 and 6, each lever vertical wall 74 extends in the front-rear direction from the inclined portion 73b to the upper wall main body portion 73a. Each lever vertical wall 74 is disposed so as to be located on the inner surface side of the side wall portion 63 of the base 6. The side wall portion 63 is a guide wall for preventing the lever 7 from shifting left and right when it rotates (for guiding its position in the left and right direction).

[0041] 6 and 7, each lever vertical wall 74 has a lever step 74b whose width in the left-right direction narrows toward the hinge axis 7a. The lever step 74b is formed by positioning the outer surface of the lever vertical wall 74 on the inner side in the left-right direction. The lever step 74b is provided between the front end 74a of the lever vertical wall 74 and the bent portion 73c in the front-rear direction.

[0042] As shown in FIGS. 2 and 3, a hinge pin 71 is provided at the front end 74a. A second stopper portion 63g is disposed between the hinge pin 71 and the lever step 74b in the front-rear direction. The lever step 74b abuts against the second stopper portion 63g from its rear side when the piston 33 is located at the first position P1. A lever front wall 75 extends inward in the left-right direction from the front end 74a. The lever front wall 75 extends in the up-down direction when the operating piece 72 is not pressed in. The lever front wall 75 is located behind the first stopper portion 63d. The lever front wall 75 abuts against the first stopper portion 63d from its rear side when the piston 33 is located at the first position P1.

[0043] The hinge pin 71 is a protrusion that protrudes outward in the left-right direction from the front end portion 74a. The hinge pin 71 is rotatably supported by the hinge hole 63f. This allows the lever 7 to rotate in the up-and-down direction around the hinge axis 7a of the hinge pin 71. Because the hinge pin 71 is located on the front side of the lever 7, pressing down the operating piece 72 of the lever 7 allows the lever 7 to rotate around the hinge pin 71.

[0044] As shown in Figures 2 and 3, an abutment portion 76 is provided between the hinge pin 71 and the operating piece 72 in the front-rear direction. The abutment portion 76 is a plate-shaped rib that protrudes downward from the lever upper wall 73 and extends in the front-rear direction. More specifically, the abutment portion 76 protrudes downward from the lower surfaces of the upper wall main body portion 73a and the inclined portion 73b, extends in the front-rear direction, and has a generally downward-facing triangular shape. Because the abutment portion 76 is provided across the upper wall main body portion 73a and the inclined portion 73b, bending deformation of the lever upper wall 73 at the bent portion 73c between the upper wall main body portion 73a and the inclined portion 73b can be suppressed.

[0045] A horizontal portion 76b extending in the front-rear direction is provided at the lower end 76a of the abutment portion 76. The horizontal portion 76b abuts against the pressing portion 34 from above when the piston 33 is located at the first position P1 (when the operation piece 72 is not pressed in). When the operation piece 72 is pressed in, the abutment portion 76 abuts against the pressing portion 34 from above, making it possible to press down the pressing portion 34 or to operate the pump 3. A plurality of abutment portions 76 (two in this embodiment) are arranged spaced apart in the left-right direction to evenly press the pressing portion 34.

[0046] The hinge axis 7a is located in front of the pressing portion 34, and the operating piece 72 is located behind the abutment portion 76. Therefore, by utilizing the principle of leverage, the force applied to the operating piece 72 as the point of force can be rotated around the hinge axis 7a as the fulcrum to generate a large force at the abutment portion 76 as the point of action.

[0047] As shown in FIGS. 2 and 7 , the operation piece 72 is located at the widthwise center of the upper wall main body 73a and is formed integrally with the upper wall main body 73a. The operation piece 72 has a generally constant width W3, set to, for example, 18.6 mm, to allow for ease of placement of the user's finger. The upper surface 72a of the operation piece 72 is provided with a recess 72b, which is recessed downward. The recess 72b is formed in a generally elliptical shape with a major axis extending in the front-to-rear direction to fit the shape of the user's thumb. The recess 72b is provided with multiple protrusions 72c that extend in the widthwise direction and protrude upward to prevent the user's finger from slipping. In this embodiment, four protrusions 72c are arranged at equal intervals in the recess 72b. In this embodiment, the width D1 of the protrusions 72c in the front-to-rear direction is set to 1 mm.

[0048] As shown in Figures 2 and 3, the left-right width W3 of the operating piece 72 is narrower than the width W4 between the handle side wall portions 62c corresponding to the mounting position of the operating piece 72, and when the pressing portion 34 is pressed so that the piston 33 is positioned at the second position P2, the operating piece 72 is formed to fit along the back surface of the handle 62 (the upper surface of the main body portion 62b).

[0049] The push bottle 1 and push kit 5 according to this embodiment have the following advantages.

[0050] The push bottle 1 according to one embodiment of the present invention includes a container 2 having a mouth portion 21, A pump 3, a cap 31 that seals the mouth 21; a piston (movable part) 33 that is movable between a first position P1 located above and a second position P2 located below; an elastic member 36 that biases the movable portion 33 from the second position P2 toward the first position P1; a pressing portion 34 that is pressed when the movable portion 33 is moved to the second position P2; and A nozzle 35 is located in front of the pressing part 34 and discharges the fluid stored in the container 2 when the movable part 33 moves to the second position P2. a pump 3 having a a base 6 fixed to the cap 31 and having a handle 62; a lever 7 supported on the base 6 so as to be rotatable about a hinge axis 7a extending in the left-right direction and having an abutment portion 76 that abuts against the pressing portion 34 from above; Equipped with.

[0051] According to the present invention, there is no need to prepare a dedicated push bottle, and by attaching a base 6 and a lever 7 to a general-purpose push bottle, a push bottle 1 equipped with a lever 7 can be inexpensively and easily constructed while using a general-purpose pump.

[0052] The handle 62 is disposed at a circumferential position different from the discharge direction of the nozzle 35 around the pressing portion 34, and extends downward at an incline. The gap S1 between the handle 62 and the container 2 increases downward.

[0053] According to this configuration, when a user holds the handle 62, interference between the hand and the container 2 can be easily suppressed, and the handle 62 is easy to hold.

[0054] The hinge axis 7a is located in front of the pressing portion 34, The lever 7 has an operating piece 72 that is operated by being pushed downward, located rearward of the contact portion 76 .

[0055] According to this configuration, by utilizing the principle of leverage, a force applied to the operating piece 72 as a point of force can be generated at the abutment portion 76 as a point of action by a rotational movement with the hinge axis 7a as a fulcrum.

[0056] When the pressing portion 34 is pressed so that the movable portion 33 is positioned at the second position P2, the operation piece 72 fits along the rear surface of the handle 62 (the upper surface of the main body portion 62b).

[0057] According to this configuration, by rotating the operation piece 72 until it is aligned with the rear surface of the handle 62, it is easy to grasp the push-in end position of the operation piece 72.

[0058] The lever 7 has a lever upper wall 73 that connects the hinge axis 7a and the operating piece 72, and the lever upper wall 73 is inclined upward and rearward when the operating piece 72 is not being pushed in.

[0059] According to this configuration, the lever 7 can be positioned higher, making it easier to increase the distance between the operating piece 72 and the handle 62, and as a result, it is easier to ensure the amount of discharge by the pump 3.

[0060] The contact portion 76 is a rib that protrudes downward from the lever upper wall 73 and extends in the front-rear direction.

[0061] According to this configuration, the upper wall of the lever 7 is reinforced by the rib, so that bending deformation in the plane along the front-rear and up-down directions of the lever 7 due to the operating force input to the operating piece 72 is suppressed.

[0062] The lever 7 has a pair of left and right lever vertical walls 74 extending downward from both left and right edges of the lever upper wall 73, The base 6 has a pair of left and right guide walls 63 that guide the position of the lever vertical wall 74 in the left and right direction.

[0063] According to this configuration, the lever vertical wall is guided by the guide wall when the lever rotates, so that the lever can be rotated stably.

[0064] The base 6 has a base opening 64 on the front side that opens in the front-rear direction and in which the nozzle 35 is located. The base opening 64 has a size that does not hinder the vertical movement of the nozzle 35 that accompanies the movement of the piston 33 between the first position P1 and the second position P2.

[0065] According to this configuration, the vertical movement of the nozzle 35 in accordance with the rotation of the lever 7 is not hindered by the base 6 .

[0066] The lever vertical wall 74 has a lever step portion 74b whose width in the left-right direction narrows toward the hinge axis 7a, The guide wall 63 has a hinge hole 63f through which the hinge axis 7a is inserted, and a base step portion 63g whose width in the left-right direction narrows toward the hinge hole 63f. When the piston 33 is located at the first position P1, the lever step 74b abuts against the base step 63g, preventing the lever 7 from pivoting forward.

[0067] According to this configuration, when the piston 33 is located at the first position P1, the lever 7 is prevented from rotating forward, and the lever 7 can be held at a position where the abutting portion 76 substantially abuts against the pressing portion .

[0068] The pump 3 is fitted with a tubular member 37 for sucking up the fluid in the container 2. The tubular member 37 comprises a first portion 38 having an upper end 38a connected to the pump 3 and extending in the vertical direction, a second portion 39 having a lower end 39b located at the bottom corner 24 formed by the bottom 22 and peripheral wall 23 of the container 2, and a connecting member 40 connecting the lower end 38b of the first portion 38 to the upper end 39a of the second portion 39, and the connecting member 40 is bent so that the second portion 39 is inclined in the vertical direction.

[0069] According to this configuration, the tubular member 37 can suck up the fluid remaining in the bottom corners 24 of the container 2, making it easier to discharge the fluid contained in the container 2 to the last drop.

[0070] The push kit (5) is attached to a push bottle that includes a container (2) having a mouth (21), a cap (31) that seals the mouth (21), a piston (33) that is movable between a first position (P1) located above and a second position (P2) located below, an elastic member (36) that urges the piston (33) from the second position (P2) toward the first position (P1), a pressing portion (34) that is pressed when the piston (33) is moved to the second position (P2), and a nozzle (35) that is located in front of the pressing portion (34) and discharges fluid stored in the container (2) when the piston (33) moves to the second position (P2). The push kit (5) is attached to a push bottle that includes a container (2) having a mouth (21), a cap (31) that seals the mouth (21), a piston (33) that is movable between a first position (P1) located above and a second position (P2) below, an elastic member (36) that urges the piston (33) from the second position (P2) toward the first position (P1), a pressing portion (34) that is pressed when the piston (33) is moved to the second position (P2), and a nozzle (35) that is located in front of the pressing portion (34) and discharges fluid stored in the container (2) when the piston (33) moves to the second position (P2). The push kit (5) is fixed to the cap (31) and includes a base (6) that has a handle (62), and a lever (7) that is supported on the base (6) so as to be rotatable about a hinge axis (7a) that extends in the left-right direction, and has an abutment portion (76) that abuts against the pressing portion (34) from above.

[0071] According to this configuration, the same effects as those of the push bottle 1 described above can be obtained.

[0072] The distance between the bottom end 39b of the second member 39 of the annular member 37 and the bottom corner 24 (specifically, the distance S2 between the bottom end 39b and the peripheral wall 23 and / or the distance S3 between the bottom end 39b and the bottom 22) is set to 1 mm or more and 5 mm or less. If the distance S2 between the peripheral wall 23 and the bottom end 39b and / or the distance S3 between the bottom 22 and the bottom end 39b is less than 1 mm, the bottom end 39b is too close to the bottom corner 24, making it difficult to suck in the fluid. If the distance S2 and / or the distance S3 exceeds 5 mm, it is difficult to suck in all of the fluid remaining in the bottom corner 24. For example, by setting the distance S2 and / or the distance S3 to 5 mm or less, the amount of fluid remaining in the container 2 can be reduced to 10 mm or less when the container is tilted so that the bottom end 39b of the tubular member 37 is positioned downward and fluid is dispensed.

[0073] The handle angle α is preferably between 15 degrees and 45 degrees, and is set to 25 degrees in this embodiment. If the handle angle α is less than 15 degrees, it is difficult to insert a hand between the peripheral wall portion 61 and the main body portion 62b, and if it exceeds 45 degrees, the rotation range of the lever 7 becomes narrow, making it difficult to obtain a sufficient pump discharge volume.

[0074] The width W1 in the left-right direction of the upper wall main body portion 73a is preferably set to 10 mm or more, and is set to 36 mm in this embodiment. This allows the push kit 5 to be stably placed even when turned upside down (refilling placement state) when refilling fluid, as shown in Fig. 8. For example, if the width W1 in the left-right direction of the upper wall main body portion 73a is smaller than the width W in the left-right direction of the pressing portion 34 and / or if the upper wall main body portion 73a bulges upward, it may be difficult to stably place the push kit 5 in the refilling placement state.

[0075] In this embodiment, an example has been described in which the handle 62 is disposed at the rear of the push bottle 1, but this is not limited thereto, and the handle 62 may be disposed at a circumferential position around the pressing portion 34 that is different from the discharge direction of the nozzle 35. For example, the handle 62 may be disposed so as to extend in the left-right direction. With this configuration, the operating piece 72 can be pressed in while checking the discharge direction of the fluid being discharged from the nozzle 35.
