  1 to 6 show a liquid discharge container according to a first embodiment of the present invention. The liquid discharge container includes a container body 2, a mounting member 10, a poppet valve body 50, a retaining cylinder 54, and an operating member 60. Each of these members can be formed of, for example, a synthetic resin or a metal. For convenience of explanation, the basic configuration of the present invention will be described first.

  The container body 2 erects the mouth-and-neck portion 6 from the compressible trunk portion 4.

  The mounting member 10 protrudes inwardly from an upper part of the mounting cylinder part 12 fitted (screwed in the illustrated example) to the outer surface of the mouth-and-neck part 6, and the guide cylinder extends from the outer peripheral part of the inward flange 14. From the inner peripheral portion of the inward flange 14, the rotation retaining cylinder portion 24 with the vertical groove 26 is erected.

  The cylinder 30 has a flange portion 34 at the upper end of the cylinder peripheral wall 32, and the flange portion 34 is sandwiched between the mouth neck portion 6 and the inward flange 14 together with the packing P and is suspended in the container body 2. A through hole 36 is opened in the upper part of the cylinder peripheral wall 32. A lower portion of the cylinder 30 is formed in a small diameter cylindrical portion, and the mounting cylindrical portion 44 is suspended from the small diameter cylindrical portion via a tapered wall portion 38 having a small diameter at the lower end. The upper portion of the suction pipe 46 is fitted into the mounting cylinder portion 44. Further, a plurality of radial vertical ribs 40 as viewed from above are provided vertically from the inner surface of the small diameter cylindrical portion to the tapered wall portion 38. An upward step 42 is formed on the inner surface of each vertical rib 40. A coil spring S is interposed between the upward step portion 42 and a back surface of a valve seat plate portion 62b described later.

  The poppet valve body 50 is inserted into the lower half of the cylinder 30 in association with the lower part of the operating member 60. The lower half part of the illustrated poppet valve body 50 is formed in the large diameter part 50a, and the upper half part is formed in the small diameter part 50b. The same number of fins 52 as the vertical ribs 40 project radially from the outer surface of the large-diameter portion 50a, and the fins 52 are inserted between the vertical ribs 40. The poppet valve body 50 follows the up-and-down movement of the operating member 60 by frictional force with the operating member 60, the state where the fin 52 contacts the lower end of the coil spring locked to the upward step portion 42, and the poppet valve body 50. It forms so that a lower end may raise / lower between the state contact | abutted to the inner surface of the taper-shaped wall part 38. FIG. A first check valve V <b> 1 is formed by the lower end of the poppet valve body 50 and the inner surface of the tapered wall portion 38. Although the poppet valve body 50 is installed between the cylinder 30 and a piston guide 62 described later, the poppet valve body 50 is disposed with a backlash. The first check valve V1 is assumed to be open when the main body 60a of the operating member 60 is pushed down shallowly by the push-down means D described later as shown in FIG.

  The retaining cylinder 54 is positioned above the through hole 36 and is fitted to the upper end portion of the cylinder peripheral wall 32. In the illustrated example, a short rib attached to the outer surface of the cylinder wall of the retaining cylinder is sandwiched between the inner peripheral portions of the flange portion 34 and the inward flange 14. However, such a structure can be changed as appropriate.

  As shown in FIG. 1, the actuating member 60 includes a piston guide 62, a stem 64, a cylindrical piston 65, and a discharge head 66. Among the operating members, the piston guide 62, the stem 64, and the discharge head 66 are configured to move up and down integrally as a main body 60a of the operating member 60 (see FIG. 3).

  The piston guide 62 is inserted into the upper half of the cylinder 30 and is provided with a ring-shaped valve seat plate portion 62b extending horizontally outward from the lower end of the vertical guide tube portion 62a, and the valve seat plate portion. A leg tube portion 62c extends outwardly and downward from 62b. In the illustrated example, a liquid passage hole 63 is opened between the valve seat plate portion 62b and the leg tube portion 62c. The inner surface of the lower end of the guide cylinder 62a is closed by the lower end of the poppet valve body 50.

  The stem 64 hangs from the small-diameter cylindrical portion 64c via the large-diameter portion 64b. The stem 64 has a lower portion of the small-diameter cylindrical portion 64c fitted to the outer surface of the guide cylindrical portion 62a so that the remaining portion of the small-diameter cylindrical portion extends above the cylinder 30 and the large-diameter cylindrical portion 64a. Is inserted below the retaining cylinder 54 into the cylinder 30. In the small diameter cylindrical portion 64c, a plurality of contact ribs 64d are provided vertically, and a liquid passage L communicating with the upper end portion of the stem 64 is formed between the small diameter cylindrical portion 64c and the guide cylindrical portion 62a. . However, this structure can be changed as appropriate, and for example, a liquid passage that penetrates the guide tube portion 62a may be opened.

  The cylindrical piston 65 is slidably inserted along the inner surface of the cylinder 30 between the valve seat plate portion 62b and the large-diameter cylindrical portion 64a, and is relative to the main body 60a of the operating member 60. Can be moved up and down.

  Here, “relatively rising” means that the cylindrical piston 65 descends together with the main body 60a, but the descending width of the cylindrical piston 65 is smaller than that of the main body 60a. It is assumed that the cylindrical piston 65 rises together with the main body 60a, but the rising width of the cylindrical piston 65 is smaller than that of the main body 60a.

  In the illustrated example, the cylindrical piston 65 has a double cylindrical shape in which the vertical intermediate portion of the outer cylindrical portion 65a is connected to the inner cylindrical portion 65b via the connecting portion 65c, and the upper end portion and the lower end portion of the outer cylindrical portion 65a are It is in contact with the inner surface of the cylinder 30. The upper end portion of the inner cylinder portion 65 b is in sliding contact with the inner surface of the large diameter cylinder portion 64 a of the stem 64. Further, the lower end of the inner cylinder portion 65b can be brought into contact with the upper surface of the valve seat plate portion 62b, and a second check valve V2 is formed between the lower end of the inner cylinder portion 65b and the valve seat plate portion. A gap g is provided between the connecting portion 65c and the lower end of the large diameter cylindrical portion 64a of the stem 64.

  The discharge head 66 is attached to the upper end portion of the stem 64. In the illustrated example, the connecting cylinder portion 70A is suspended from the center of the rear surface of the ejection head 66, and the base cylinder portion 70B is suspended from the outer periphery of the rear surface. The connecting cylinder portion 70 </ b> A is connected to the upper end portion of the stem 64. Further, the base tube portion 70B is fitted to the outer surface of the rotation-preventing tube portion 24. And the vertical protrusion is provided in the inner surface of the base cylinder part 70B, and the rotation stop means T is formed by engaging this vertical protrusion with the vertical groove 26 of the cylinder part 24 for rotation prevention.

  In the above configuration, when the discharge head 66 is pushed down, the poppet valve body 50 is lowered in conjunction with the operation member 60 and the first check valve V1 is closed. Further, since the cylindrical piston 65 descends later than the main body 60a of the operating member 60, the second check valve V2 is opened, and the liquid in the cylinder 30 is sprayed from the discharge head 66 through the liquid passage L. . When the push-down of the discharge head 66 is released, the main body 60a of the actuating member 60 rises prior to the cylindrical piston 65, so that the second check valve V2 is closed and the poppet valve body follows the main body 60a. Since 50 also rises, the first check valve V1 opens. As a result, the liquid in the container is sucked into the cylinder.

  In the present invention, first, the ejection head 66 is composed of a head base 68 and a cover member 82. The head base 68 has the connecting cylinder part 70A and the base cylinder part 70B, and further has a first discharge hole 76 for spraying liquid and a second discharge hole 80 for dropping liquid on the outer peripheral surface. The first discharge hole 76 and the second discharge hole 80 are arranged on the outer peripheral surface of the head base 68 so as to be separated by a certain angle (90 ° in the illustrated example). The first discharge hole 76 communicates with the stem 64 via the first discharge path 74, and the second discharge hole 80 communicates with the stem 64 via the second discharge path 78. Further, a plug hole 72 is formed in the upper surface of the head base 68, and the plug hole 72 is continuous from the upper end portion of the stem 64 to the first discharge path 74 and the second discharge path 78. .

  The cover member 82 is rotatably fitted to the outer surface of the head base 68. The illustrated cover member 82 has an outer peripheral wall 88 depending from the outer peripheral portion of the top wall 84, and the outer peripheral wall 88 is fitted to the outer peripheral surface of the head base 68. A small-diameter and long-legged plug cylinder portion 86 and a large-diameter and short-legged auxiliary cylinder portion 87 are suspended from the center of the back surface of the top wall 84. The auxiliary cylinder portion 87 is in contact with the upper surface portion of the head base 68 around the plug hole 72.

  The plug cylinder 86 is fitted in the plug hole 72 in a liquid-tight and rotatable manner, and a communication port 86 a is opened at a part of the plug cylinder 86 in the circumferential direction. With this configuration, the plug cylinder portion 86 shields the first discharge path 74 and the second discharge path 78, and the communication port 86 a of the first discharge path 74 and the second discharge path 78 is rotated by the rotation of the cover member 82. The channel switching means E is formed by providing the one channel so as to be opened when it coincides with the one channel.

  A window 90 is opened in the outer peripheral wall of the cover member 82 corresponding to the height of the first discharge hole 76 and the second discharge hole 80. The window 90 opens the first discharge hole 76 when the first discharge path 74 is opened by the flow path switching means E, and opens the second discharge hole 80 when the second discharge path 78 is opened. To be formed. In a preferred illustrated example, a first window 90 a for the first discharge hole 76 and a second window 90 b for the second discharge path 78 are formed as the window 90, and horizontal from the periphery of the second window 90 b. A nozzle 92 protrudes outward in the direction. In the state of FIG. 2 (pump operation mode), the first discharge hole 76 is opened to the outside through the first window 90 a, and the second discharge hole 80 is shielded by the outer peripheral wall 88. However, this structure can be changed as appropriate.

  Further, in the present invention, as shown in FIG. 1, a convex first engaging portion 18 is provided on the upper inner surface of the guide tube portion 16 and a convex second engaging portion 94 is provided on the lower outer surface of the outer peripheral wall 88 in the circumferential direction. When the cover member 82 is rotated, the first engaging portion 18 rides on the second engaging portion 94 when the cover member 82 is rotated (see FIG. 4), and the pressing means E that pushes down the main body 60a of the operating member 60 is provided. Forming.

In the illustrated example, the first engagement portion 18 and the second engagement portion 94 each have an engagement slope I that is inclined in the circumferential direction, and the engagement slope I and the first engagement portion 18 of the second engagement portion 94. The engagement slope I slides smoothly, so that the first engagement portion 18 can be smoothly climbed. The first engaging portion 18 rides on the second engaging portion 94. As a result, the actuator member 60 is lowered by a certain width h from the upper limit position of the actuating member 60 drawn by an imaginary line in FIG. On the other hand, the cylindrical piston 65 does not descend. As a result, the second check valve V2 is opened, and the first check valve V1 is also opened at this time, so that the liquid in the container body 2 can be discharged by squeezing the body portion 4 (body portion). Squeezing operation mode). In this state, it is assumed that the stem 64 communicates with the second discharge hole 80. In this state, the second discharge hole 80 is opened to the outside through the second window portion 90 b, and the first discharge hole 76 is shielded by the outer peripheral wall 88.
The shapes of the first engaging portion and the second engaging portion may be any shape as long as the rotational force of the ejection head can be converted into the pressing force of the operating member. For example, one of the two may be an engagement recess (engagement groove), and the other may be formed as an engagement projection that slides within the engagement recess.

  In addition, the guide tube portion 16 has a gap b between the first engagement portion 18 and a locking rib positioned below the first engagement portion 18 in the vertical direction on the lower inner surface of the guide tube portion 16. The lowering restricting means R of the main body 60a of the operating member 60 is used.

  Further, as indicated by an imaginary line in FIG. 1, a pair of rotation restricting ribs 22 is provided vertically on the inner surface of the guide tube portion 16, and an engaging rib 96 is provided on the outer surface of the outer peripheral wall 88. The rotation range of the ejection head 66 can be limited to a certain range (about 180 degrees in the illustrated example) so that the 96 moves only between the pair of rotation regulating ribs 22.

  According to the above configuration, when the discharge head 66 is rotated from the pump operation mode shown in FIG. 2 to the squeezing operation mode, the main body 60a of the operating member 60 is lowered by the action of the push-down means D, and the second check valve Since V2 is opened, the content liquid can be dropped from the second discharge hole 80 when the container is tilted with the opening portion of the second discharge hole 80 directed toward a small dish and the barrel is squeezed.
