The illustrated first upright cylinder portion 17 is formed in a vertical cylinder shape. The peripheral wall portion below the outward flange-like wall portion 18 is composed of a first peripheral wall portion 16a on the lower end side and a second peripheral wall portion 16b whose diameter is expanded from the upper end of the first peripheral wall portion 16a through a step. In the illustrated example, a knurled first swivel means k1 is formed over the entire outer surface of the first upright cylinder portion 17.

The outward flange-like wall portion 18 has an outer peripheral portion 18c projecting outward from the inner peripheral portion 18a via the second upright cylindrical portion 18b, and the packing p is attached to the lower surface of the outer peripheral portion 18c. Yes. A first lateral rib q1 is provided around the inner surface of the second upright cylinder portion 18b. A ring groove-like fitting recess 19 is formed between the second upright tube portion 18 b and the first upright tube portion 17. In the illustrated example, a first vertical rib r1 having a substantially triangular cross section is provided vertically from the outer surface of the upper end portion of the second peripheral wall portion 16b to the lower surface of the inner peripheral portion 18a.

  The ring member C is fitted to the first upright cylindrical portion 17 which is the upper end portion of the cylinder B, and is formed by the mounting base 30 and the locked cylindrical portion 31.

The mounting base 30 prevents rotation on the outer ring cylindrical portion 30b fitted into the fitting concave portion 19 so as to be prevented from coming out upward and the inner peripheral upper end portion of the first upright cylindrical portion 17. The upper ends of the inner ring cylinder part 30c and the inner ring cylinder part 30c thus fitted are connected by an annular top plate part 30a. The illustrated outer ring cylinder part 30b is longer than the inner ring cylinder part 30c and has a length that reaches the bottom surface of the fitting recess 19 (the upper surface of the inner peripheral part 18a). This is to increase the fitting force by taking a sufficient fitting length. At least one (a plurality in the illustrated example) second lateral rib q2 is provided in the circumferential direction at the lower part of the outer peripheral surface of the outer ring cylinder 30b, and the outer ring cylinder 30b is forced into the fitting recess 19.

The second swivel means k2 and the first swivel means k1 are engaged with each other to form the cylinder B. The rotation of the ring member C with respect to is prevented. The structure of the both-turn fastening means can be changed as appropriate.

  The locked cylinder portion 31 is for engaging and fixing to a locking cylinder portion 70 described later, and stands up from the inner peripheral edge portion of the top plate portion 30 a of the mounting base 30. The illustrated locked cylinder portion 31 is formed in a screw cylinder portion having a screw structure on the outer surface, but any structure may be used as long as it can be locked to the locking cylinder portion 70. The inner surface of the locked cylindrical portion 31 and the inner surface of the inner ring cylindrical portion 30c are substantially flush with each other in the illustrated example, and a second vertical rib r2 is provided vertically on both the surfaces.

  Furthermore, in the example of illustration, while making the internal diameter of the said 2nd standing cylinder part 18b and the hole diameter of the flange hole 12 of the said flange-shaped top wall part 11 into substantially the same, the said flange hole 12 of the said flange hole 12 from the upper side of the outer ring cylinder part 30b. An annular protrusion 32 having an outer diameter slightly larger than the hole diameter protrudes outward. According to the illustrated structure, the height from the upper surface of the flange-shaped top wall portion 11 to the upper surface of the top plate portion 30a of the ring member C is increased by inserting the outer link cylinder portion 30b into the fitting recess 19. As a result, the overall height of the pump is reduced (see FIG. 5).

  The check valve member D is attached to the lower end in the cylinder B. The check valve member D is fitted to the leg cylinder part 33 with a liquid passage between the inner peripheral lower end part of the peripheral wall part 16 of the cylinder B and the inner peripheral part, and the flange part 34 from the upper end of the leg cylinder part 33. The base 35 is erected through the flange portion 34.

  The leg tube portion 33 is rotatably inserted between the first check valve seat 23 and the inner surface of the peripheral wall portion 16 of the cylinder B. As a preferred embodiment, the outer surface of the leg cylinder portion 33 is in contact with an undercut projecting from the inner periphery of the peripheral wall portion 16 of the cylinder B. Further, a plurality of liquid passages in the circumferential direction may be opened in the upper half of the leg tube portion 33.

  A plurality of elastic pieces 37 project inward from the inner circumference of the leg cylinder portion 33 at a constant interval in the circumferential direction, and are pressed onto the first check valve seat 23 via the elastic pieces 37. The first check valve body 38 is supported. The first check valve body 38 and the first check valve seat 23 form a first check valve V1.

  The actuating member E is assembled to the cylinder B so as to be vertically movable in an upwardly biased state, and as shown in FIG. 1, the stem E1, the piston guide E2, the annular piston E3, the discharge head E4, And an outside air introduction hole opening / closing member E5.

  The stem E1 is fitted with a discharge head E4 at the upper end, and the lower end is inserted into the cylinder B in an upwardly biased state so as to be movable up and down, and the annular piston E3 is mounted at the lower end so as to allow relative up and down movement. It has a cylindrical shape and serves as a conduit for introducing the liquid in the cylinder B into the discharge head E4.

  In this specification, “relative vertical movement” means that both the stem and the annular piston are lifted, but the rising width of the other of the stem and the annular piston is larger than that of the other, and therefore one of them is used as a reference. The other moves to a higher position, and both the stem and the annular piston descend, but the other descending width is larger than the descending width of one of the stem and the annular piston, so the other is lower than the other It shall mean moving to a position.

  As shown in FIG. 2, the stem E1 of the first embodiment protrudes downward from a cylindrical stem main body portion 42 in a double cylindrical lower end formed by an outer cylinder portion 41 and an inner cylinder portion 40. .

  The outer cylinder portion 41 is suspended from the lower end of the stem main body portion 42 via an outward flange portion 43. The outward flange portion 43 is an outward flange portion 43 that inclines and descends outward from the lower end portion of the stem main body portion 42.

  The inner cylinder part 40 is suspended downward from the lower end of the stem body part 42 via the inward flange part 44 below the lower end of the outer cylinder part 41. In addition, a fluid passage hole 45 having a wide vertical direction extending from the inward flange portion 44 to the lower side of the inner cylinder portion 40 is formed. Moreover, the inner cylinder part 40 may be circular or polygonal. The upper half part of the inner cylinder part 40 is formed in a tapered part 40a whose lower end is tapered inwardly, and the lower half part of the inner cylinder part 40 is formed in a vertical cylinder part 40b. A pair of vertically long liquid passage holes 45 extending from the inward flange portion 44 to the tapered portion 40a are formed at opposing positions. Furthermore, a first locking rib 48 is attached to the inner surface of the inner cylinder portion 40. The liquid passage holes 45 are not limited to a pair, and may be one place or three places or more.

  The piston guide E2 is a member that is attached to the inner cylinder portion 40 of the stem E1 and restricts a range in which an annular piston E3 (described later) of the stem E1 moves. The piston guide E2 has a connection base 50 and a second check valve seat 51 for fitting to the stem E1. Since the piston guide is separate from the annular piston, it can be formed of a material (synthetic resin) that is harder than the material normally used for the piston.

  As shown in FIG. 2, the connecting base portion 50 is formed by a fitting tube portion 50a, a bottom plate 50b that closes the lower surface of the fitting tube portion 50a, and a rod-like protrusion 50c that stands from the center portion of the bottom plate 50b. ing. Although the rod-shaped protrusion 50c in the illustrated example is solid, it may be formed in a hollow cylindrical shape, for example. And the said inner cylinder part 40 is fitted in the annular groove part g formed between the fitting cylinder part 50a and the rod-shaped protrusion 50c so that rotation is impossible. On the outer surface of the rod-like protrusion 50c, an annular groove g for engaging with the first engaging rib 48 is provided, thereby constituting an engaging means for preventing the inner tube portion 40 from coming off from the connecting base portion 50. However, the structure of the locking means can be changed as appropriate.

  The second check valve seat 51 protrudes from the outer periphery of the fitting tube portion 50a to the lower position of the outer tube portion 41. The illustrated second check valve seat 51 protrudes integrally from the outer periphery of the fitting tube portion 50a, the base end portion descends outward, the lower surface of the horizontal outer peripheral portion is an annular flat surface 55, and the outer peripheral edge portion. Standing wall is set up in Further, in the first embodiment, the guide tube portion 52 is integrally suspended below the lower peripheral edge portion of the second check valve seat 51, and a plurality of circumferential guide protrusions 53 project from the outer periphery of the guide tube portion 52. doing.

  As shown in FIG. 1, the annular piston E <b> 3 has an H-shaped cross section in which a cylindrical inner sliding portion 60 and a cylindrical outer sliding portion 61 are connected to each other by an upper and lower intermediate portion connected by a connecting portion 62. It is formed in an annular shape. The internal sliding portion 60 constitutes the second check valve V2 with the second check valve seat 51. The internal slide portion 60 moves vertically away from the inner cylinder portion 40 of the stem E1, and the upper end portion is the outer cylinder portion 41. The inner periphery is slidably fitted. The external sliding portion 61 is slidably fitted to the inner periphery of the cylinder B. Therefore, the annular piston E3 has a stem between the position where the lower end portion of the internal sliding portion 60 is pressed against the second check valve seat 51 and the position where the upper surface of the connecting portion 62 is in contact with the lower surface of the outer cylinder portion 41. It is mounted so that it can move up and down relative to E1.

  The discharge head E4 hangs a small-diameter connecting cylinder 69 and a large-diameter locking cylinder 70 from the center of the back surface of the top plate 71 in a double cylinder shape, and suspends an outer peripheral wall 72 from the peripheral edge of the top plate 71. The nozzle 74 that is provided and communicates with the connecting cylinder portion 69 projects forward, and a discharge port 75 is opened at the tip of the nozzle 74. Further, the inner surface of the locking cylinder part 70 is provided with a thread, and as shown in FIG. 3, the operating cylinder E is pushed down when it is not in use so that the locking cylinder part 70 becomes the locked cylinder part 31 of the ring member C. It is configured so that it can be screwed together, and is configured so that the operating member E can be locked in a depressed state.

  The outside air introduction hole opening / closing member E5 is mounted on the outer peripheral upper portion of the stem E1 so as to be movable up and down relative to the stem E1. The outside air introduction hole opening / closing member E5 includes a base tube portion 80 in which the upper end portion is slidably fitted to the outer periphery of the stem E1 with a gap that allows introduction of outside air. The stem E1 and the base tube In this structure, the liquid can be prevented from entering through the gap with the portion 80 as much as possible. Further, an open / close cylinder part 81 that opens and closes the outside air introduction hole 24 protrudes from the lower end of the base cylinder part 80. When the operating member E in use is at the highest position, as shown in FIG. 1, the open / close cylinder portion 81 is at the position above the outside air introduction hole 24. At this time, the outside air introduction hole 24 is closed by the annular piston E3. Even when the operating member E is pushed down to discharge the liquid, the open / close cylinder 81 is located above the outside air introduction hole 24. Although not shown, the downward stepped portion 76 at the upper portion of the connecting tube portion 69 does not press the upper surface of the base tube portion 80 at the pushed-down position of the operating member E for discharging liquid. Further, as shown in FIG. 5, the open / close cylinder 81 is configured to block the outside air introduction hole 24 when the operation member E is pushed down and locked.

  The coil spring F is interposed between the lower surface of the second check valve seat 51 and the flange portion 34 of the check valve member D, and always urges the stem E1 and thus the operating member E upward.

  In the above configuration, when the pump is not used (for example, when shipped as a product), as shown in FIG. 5, the operating member E is pushed down so that the locking cylinder portion 70 of the discharge head E4 is engaged with the ring member C. Locked to the stop tube portion 31. As a result, the operating member E can be locked in the lowered state. At this time, the outside air introduction hole opening / closing member E <b> 5 is pushed down, and the opening / closing cylinder portion 81 closes the outside air introduction hole 24. Further, the pedestal 35 of the check valve member D abuts on the lower surface of the connection base 50. In the present invention, since the outer ring cylindrical portion 30b of the ring member C is configured to be inserted into the fitting recess 19 of the cylinder B, the normal use state shown in FIG. However, the overall height of the pump is relatively small compared to those not configured as such. Further, the outer ring tube portion 30b is sandwiched between the inner peripheral surface s1 and the outer peripheral surface s2 of the fitting recess 19, so that the fitting force is improved.

  Next, when the pump is used, the discharge head E4 is rotated to unscrew the locking cylinder part 70 from the locked cylinder part 31. Further, from the state of FIG. 1, when the discharge head E4 is pushed down, the liquid in the cylinder B is pressurized, and the annular piston E3 pushed up by the liquid pressure rises relative to the stem E1 to raise the second check valve V2. Is opened, and the pressurized liquid is introduced into the stem E <b> 1 through the second check valve V <b> 2 and the liquid passage hole 45, and then discharged from the discharge port 75 of the nozzle 74 to the outside.

  When the pressing of the discharge head E4 is released, the operating member E is raised by the upward biasing force of the coil spring F, and at this time, the annular piston E3 is lowered relative to the stem E1 due to the negative pressure in the cylinder B. The second check valve V2 is closed and the first check valve V1 is opened, so that the liquid in the container body 100 is introduced into the cylinder B through the suction pipe 26.
