And a pipe holder 28 that is fixed to the tip 13. The rear end of the pipe holder 28 is inserted into the reduced diameter portion 14 a at the distal end portion of the inner cylinder 14.

  As shown in FIG. 3, the delivery mechanism of the liquid delivery container 10 for delivering the liquid in the tank T to the brush 24 includes a knock body 20 that can be projected and retracted on the front shaft 12 constituting the main body, and a knock. The rotating member 30 on which the body 20 directly acts, the engaging member 32 disposed on the front side of the rotating member 30, the inner cylinder 14, the anti-rotation member 34 provided at the rear end portion of the inner cylinder 14, and the front shaft A piston rod guide 36 fixed to the piston 12, a piston rod 38 screwed with the piston rod guide 36, a piston 40 connected to the tip of the piston rod 38 and slidable in the tank portion T, and an engagement member And a return spring 42 as an urging member for applying an urging force to 32.

  The inner cylinder 14 and the rotation prevention member 34 constitute a transmission member to which the rotation from the rotation member 30 is transmitted, and the piston rod 38 and the piston 40 constitute a feeding body for feeding out the liquid in the tank portion T. The rotating member 30, the inner cylinder 14, the anti-rotation member 34, and the piston rod 38 constitute a conversion mechanism that converts the knock of the knock body 20 into an axial forward movement in the main body of the feeding body, The return spring 42 constitutes a rotation control mechanism that regulates the rotation direction of the rotating member 30. However, this example is an example, and the transmission member, the conversion mechanism, and the rotation control mechanism can be configured by arbitrary members.

  A spacer 44 is disposed in the rear shaft 16, and the rear shaft 16 and the spacer 44 are fitted to a piston rod 38 that is a feeding body to constitute a second conversion mechanism that performs initial feeding of the piston 40. The spacer 44 constitutes a transmission member that transmits the rotation of the rear shaft 16 to the piston rod 38.

Hereinafter, each member will be described in detail.
First, the knock body 20 has a substantially U-shaped cross section, and a rectangular cutout portion 20a is formed at the lower ends of both side surfaces thereof. It becomes the action surface 20b which acts. Further, a retaining rib 20c is formed in a portion adjacent to the notch 20a on the inner side surface of the knock body 20.

  As shown in FIG. 4, the rotating member 30 has a cylindrical shape, and the reduced diameter portion 14 a of the inner cylinder 14 passes through the inside thereof. On the side surface of the rotating member 30, protrusions 30 a and 30 a are formed in which the action surface 20 b of the knock body 20 can be pressed. Although two protrusions 30a are formed for balance, in fact, only one of the protrusions 30a is always the knock receiving protrusion that receives the knocking force of the knock body 20.

  In the vicinity of the protrusions 30a, 30a, retaining recesses 30b, 30b are formed. The retaining recess 30b engages with the retaining rib 20c when the knock body 20 is not knocked. The engagement between the retaining recess 30b and the retaining rib 20c is set so that the retaining rib 20c cannot move in the direction of the opening 12a but can move in the direction opposite to the opening 12a. (See FIG. 5).

  A plurality of cam inclined surfaces 30c are formed at the tip of the rotating member 30, and the cam inclined surfaces 30c are inclined with respect to the axial direction. A plurality of ratchet teeth 30 d that are elastically deformable in the axial direction are formed at the rear end of the rotating member 30.

  Next, as shown in FIG. 6, the engaging member 32 disposed in front of the rotating member 30 has a cylindrical shape, and the reduced diameter portion 14 a of the inner cylinder 14 passes through the inside thereof. At the rear end of the engaging member 32, a cam inclined surface 32a that engages with and slides on the plurality of cam inclined surfaces 30c of the rotating member 30 is formed. The cam inclined surface 32a is inclined with respect to the axial direction. ing. A plurality of anti-rotation grooves 32b extending in the axial direction are formed on the peripheral surface of the engaging member 32. The anti-rotation rib 12b formed on the inner peripheral surface of the front shaft 12 is formed in the anti-rotation groove 32b. (See FIG. 5) is inserted, whereby the engagement member 32 can move in the axial direction with respect to the front shaft 12, but cannot rotate with respect to the front shaft 12. .

  As shown in FIG. 5A, in the normal state where the knock body 20 is not knocked, the rotating member 30 has its cam slope so that the projections 30a, 30a are not horizontal but hold an oblique state. 30 c is engaged with the cam slope 32 a of the engaging member 32. Since the engaging member 32 is biased toward the rotating member 30 by the return spring 42, the engagement between the cam inclined surface 30c and the cam inclined surface 32a is maintained. A knock receiving protrusion 30a, which is one of the protrusions 30a, is close to the action surface 20b of the knock body 20.

  Next, as shown in FIG. 7, the inner cylinder 14 that defines the tank portion T and that constitutes the transmission member includes a reduced diameter portion 14 a at the front end portion and an enlarged diameter portion 14 b at the rear end portion. In the boundary step portion 14c between the reduced diameter portion 14a and the enlarged diameter portion 14b, saw teeth 14d are continuously formed in the circumferential direction. The saw tooth 14 d can be engaged with the ratchet tooth 30 d of the rotating member 30. The saw tooth 14d and the ratchet teeth 30d constitute a first ratchet mechanism. A plurality of fitting notches 14e are formed at the rear end portion of the inner cylinder 14.

  The detent member 34 provided at the rear end portion of the inner cylinder 14 has a cylindrical shape. As shown in FIG. 8, on the outer peripheral surface of the rotation preventing member 34, there are provided a plurality of fitting protrusions 34a that fit into the fitting notches 14e of the inner cylinder 14, and these fitting protrusions 34a are provided with the fitting notches 14e. The inner cylinder 14 and the rotation preventing member 34 are integrally connected. Although it is possible to configure the inner cylinder 14 and the rotation prevention member 34 as an integral part, it is desirable that they are separate parts in terms of molding.

  An inner cylinder part 34b is formed inside the rotation stopper 34, and a non-circular hole 34c through which the piston rod 38 passes is formed at the center of the inner cylinder part 34b. The cross-sectional shape of the piston rod 38 is a non-circular shape, and the non-circular hole 34c matches the cross-sectional shape of the piston rod 38, so that the piston rod 38 cannot rotate relative to the detent member 34. Become.

  A plurality of ratchet teeth 34d that are elastically deformable in the axial direction are formed at the rear end of the rotation preventing member 34.

  Next, as shown in FIG. 9, the piston rod guide 36 disposed behind the anti-rotation member 34 has a cylindrical shape, and a number of anti-rotation ribs extending in the axial direction on the outer peripheral surface thereof. 36a is formed. The rotation-preventing rib 36 a is fitted into a rotation-preventing groove 12 c formed on the front shaft 12, whereby the piston rod guide 36 is prevented from rotating with respect to the front shaft 12. Further, the piston rod guide 36 is fixed to the front shaft 12 by being sandwiched between the rotation preventing member 34 and the spacer 44. Further, an annular protrusion 36 b formed on the outer peripheral surface of the piston rod guide 36 is fitted into the recess in the rear shaft 16 and is fixed so as to be rotatable relative to the rear shaft 16.

  An inner cylinder portion 36c is formed inside the piston rod guide 36, and a female screw hole 36d into which a male screw 38a formed on the outer peripheral surface of the piston rod 38 is screwed into the center of the inner cylinder portion 36c. Is formed. The male screw 38a of the piston rod 38 and the female screw hole 36d of the piston rod guide 36 constitute a screw mechanism.

  Furthermore, a sawtooth 36e is continuously formed in the circumferential direction on a surface formed between the outer cylinder portion and the inner cylinder portion 36c of the piston rod guide 36 and extending in the circumferential direction facing the front. The rear end portion of the rotation prevention member 34 is inserted between the outer cylinder portion and the inner cylinder portion 36c of the piston rod guide 36, and the saw tooth 36e can mesh with the ratchet teeth 34d of the rotation prevention member 34. It has become. The saw tooth 36e and the ratchet tooth 34d constitute a second ratchet mechanism.

  Next, as shown in FIG. 10, the spacer 44 disposed behind the piston rod guide 36 has a cylindrical shape, and a concavo-convex portion 44 a having a large number of concavo-convex portions on the outer peripheral surface of the rear end portion. Further, an inner cylinder part 44b is formed in the inside, and a non-circular hole 44c through which the piston rod 38 passes is formed at the center of the inner cylinder part 44b. The non-circular hole 44 c matches the cross-sectional shape of the piston rod 38, so that the piston rod 38 cannot rotate relative to the spacer 44 and can slide relative to the spacer 44.

  As shown in FIG. 11, a plurality of protrusions 16 a that fit into the concavo-convex portions 44 a of the spacer 44 are formed inside the rear shaft 16 to which the spacer 44 is inserted and fixed to the bottom of the spacer 44. As a result, the rear shaft 16 cannot rotate relative to the spacer 44.

  In the liquid delivery container 10 having the delivery mechanism configured as described above, the tank L is filled with the liquid L, but a certain amount of air exists between the tank T and the tip opening.

  Therefore, before shipping, the rear shaft 16 is rotated in a predetermined direction. When the spacer 44 rotates together with the rotation of the rear shaft 16, the piston rod 38 in the last retracted position rotates. The rotation preventing member 34 and the inner cylinder 14 rotate together with the rotation of the piston rod 38, but the saw-tooth 14 d can slide with respect to the ratchet teeth 30 d, and the first ratchet mechanism moves relative to the rotating member 30 of the inner cylinder 14. Allow rotation. Further, the ratchet teeth 34d of the rotation preventing member 34 can slide on the saw teeth 36e of the piston rod guide 36, and the second ratchet mechanism also allows the rotation preventing member 34 to rotate.

  When the piston rod 38 rotates in this manner, the piston rod 38 is screwed into the female screw hole 36d of the piston rod guide 36 fixed to the front shaft 12, so that the piston rod 38 moves forward in the axial direction and is connected to the piston rod 38. The piston 40 is pushed forward. The piston 40 can slide the tank portion T to discharge air from the inside.

  Since the rotation operation of the rear shaft 16 can be performed continuously, even if it is performed by a manufacturer before shipment, the workability is good.

  If the rear shaft 16 is rotated in the direction opposite to the predetermined direction during the operation of the rear shaft 16, the ratchet teeth 34 d of the detent member 34 mesh with the saw teeth 36 e of the piston rod guide 36. It cannot rotate in the direction, and the rear shaft 16 cannot rotate. Therefore, the rear shaft 16 can be rotated only in a predetermined direction corresponding to the forward movement of the piston rod 38 by the second ratchet mechanism.

  When the piston rod 38 and the piston 40 move forward in the axial direction by a predetermined distance, the rear end of the piston rod 38 escapes from the spacer 44, so that the rotation of the rear shaft 16 is no longer transmitted to the piston rod 38. Are shipped to the user.

  When the user uses the liquid delivery container 10, the cap 19 is removed and the liquid L is supplied using the brush 24. The liquid L from the tank portion T is supplied to the brush 24 via the pipe holder 28 and the tip pipe 26.

  Further, when the liquid L is fed out from the tank portion T, the knock body 20 is pressed and pushed out into the front shaft 12. Since the working surface 20b of the knock body 20 presses the knock receiving projection 30a of the rotating member 30 downward in FIG. 5A, the rotating member 30 rotates clockwise in FIG. 5A. When the rotating member 30 rotates, the ratchet teeth 30d of the rotating member 30 mesh with the saw teeth 14d of the inner cylinder 14, and this first ratchet mechanism is used to transmit the clockwise rotation of the rotating member 30 to the inner cylinder 14. The inner cylinder 14 rotates in the same direction, and the detent member 34 rotates together. The ratchet teeth 34d of the detent member 34 can slide on the saw teeth 36e of the piston rod guide 36, and the second ratchet mechanism allows the detent member 34 to rotate. Since the piston rod 38 rotates together with the rotation of the rotation preventing member 34 and is screwed into the female screw hole 36d of the piston rod guide 36, the piston rod 38 advances in the axial direction. Thus, since the piston 40 connected to the piston rod 38 is pressed forward, the piston 40 can slide on the tank portion T and feed the liquid L in the tank portion T forward.

  Since the piston 40 is already advanced to some extent in the tank portion T by the rotation operation of the rear shaft 16 in advance, the liquid L can be delivered by several knocks of the knock body 20 when the liquid L is first delivered. it can.

  Since the rotary member 30 rotates from the state shown in FIG. 5A to the state shown in FIG. 5B per one knock of the knock body 20, the piston rod 38 synchronized with this rotates in the same angle, The piston 40 moves in the axial direction by (rotation angle / 360) × pitch.

  Since the engaging member 32 cannot rotate when the rotating member 30 rotates to the state shown in FIG. 5B, the cam inclined surface 32 a of the engaging member 32 is different from the cam inclined surface 30 c of the rotating member 30. The engaging member 32 moves forward against the urging force of the return spring 42 in sliding contact.

  Next, when the knocking force of the knocking body 20 is released, the engaging member 32 returns to the rear by the restoring force of the return spring 42, and the cam inclined surface 30 c of the rotating member 30 slides on the cam inclined surface 32 a of the engaging member 32. Rotate counterclockwise in FIG. 5 (b) and return to the original position shown in FIG. 5 (a).

  At this time, the inner cylinder 14 and the anti-rotation member 34 are such that the ratchet teeth 34d of the anti-rotation member 34 mesh with the saw teeth 36e of the piston rod guide 36. In order to prohibit clockwise rotation, it cannot rotate with the rotating member 30. Therefore, the ratchet teeth 30d of the rotating member 30 slide on the saw teeth 14d of the inner cylinder 14, and only the rotating member 30 rotates to return to the original state, so that the knocking body 20 is moved upward as shown in FIG. Return to position.

  When not knocked, the engaging member 32 is urged backward by the return spring 42 and the rotating member 30 is fixed in the posture shown in FIG. It does not rotate.

  Thus, each time the knock body 20 is knocked, the piston 40 and the piston rod 38 move forward, and the liquid L can be fed from the brush 24 at the tip of the main body. By knocking the knock body 20, the liquid L can be fed out, so that it is not necessary to change the gripping tip shaft 12, and it is easy to operate without using both hands. Will be able to.

  Since the piston 40 is advanced in advance by the rotation operation of the rear shaft 16 before shipping, the user can feed out the liquid without excessive burden of knocking. Even if the user accidentally rotates the rear shaft 16, the piston rod 38 is separated from the spacer 44. Therefore, the rotation of the rear shaft 16 is not transmitted to the piston rod 38, and the rear shaft 16 may idle. And can prevent misoperation. Further, the operation of the rear shaft 16 may be performed by the user as well as before shipment.

  Alternatively, the distance at which the spacer 44 and the piston rod 38 are fitted to each other is extended, that is, the length of the inner cylinder portion 44b of the spacer 44 is extended, so that the rotation operation of the rear shaft 16 can be performed beyond a predetermined distance. You can also. In this case, it is necessary for the manufacturer or the like to grasp the amount of rotation of the rear shaft 16. For example, when the rotation amount of the rear shaft 16 is grasped in advance by the number of rotations, or the main body and the inner cylinder are made of a transparent material so that the tank portion can be visually recognized from the outside, the piston 44 has reached a certain position. The position of the piston 44 can also be grasped. Then, the user may be allowed to use the rotation operation of the rear shaft 16 and the knock operation of the knock body 20 separately.

  In the above embodiment, a part constituted by a plurality of members can be constituted by a single member, or a part constituted by a single member can be constituted by a plurality of members.
