  1 to 9 show a discharge apparatus according to the first embodiment of the present invention. As shown in FIG. 1, this discharge device includes a container 1 with a lid and a discharge tool 50. Each of these members can be formed of a synthetic resin material unless otherwise specified. For convenience of explanation, first, the configuration in a state where the lidded container 1 and the discharge tool 50 are separated will be described with reference to FIGS. 2 and 3.

  As shown in FIG. 2, the lidded container 1 includes a container body 2, a lid member 10, a seal member 28, and a valve member 42.

  The container body 2 has a mouth-and-neck portion 6 erected from the trunk portion 4 through a shoulder portion.

  The lid member 10 includes an outer cylinder portion 12 fitted (screwed in the illustrated example) to the outer surface of the mouth-and-neck portion 6 and an inward flange-like lid plate 14 from the upper end portion of the outer cylinder portion 12. And an inner cylinder portion 16 that hangs inward of the container body 2. A storage space S formed inside the inner cylinder portion 16 can store a lower portion of a discharge tool 50 described later.

  In the illustrated example, the inner cylindrical portion 16 is formed by hanging a small-diameter cylindrical portion 16c, which is a lower half portion, from a lower end of a large-diameter cylindrical portion 16a, which is an upper half portion, via a step portion 16b. In a preferred illustrated example, an air replacement hole 17 is opened above the large-diameter cylindrical portion 16a. The reason why the air replacement hole 17 is provided is to prevent the inside of the container body 2 from being depressurized and recessed during suction. Further, although the illustrated stepped portion 16b is formed as a downwardly inwardly inclined wall portion, the structure thereof can be changed as appropriate.

In the illustrated example, the fitting cylinder part 22 arranged concentrically is connected to the tips of a plurality of connection pieces 20 protruding inward from the lower end of the small diameter cylinder part 16c in the circumferential direction. The siphoning flow path Ws is formed by the fitting tube portion 22 and the sucking tube 26 having the upper end portion fitted in the fitting tube portion 22. A flange-like projection 24 for abutting the suction tube projects inwardly from the upper end of the inner surface of the fitting tube portion 22.

  A gap between the fitting tube portion 22 and the small diameter tube portion 16c is defined as a branch flow path Wd. The branch flow path Wd is a flow path that branches from a flow path portion between the suction flow path Ws and the inside of the soot tube portion 54 described later and returns to the container body 2.

  The seal member 28 is a cylindrical member, and is fitted on the inner surface of the inner cylinder portion 16 in a liquid-tight manner. One function of the seal member 28 is to hold the elastic cylinder portion 44 (see FIG. 2). In order to secure this function, the seal member 28 is formed by connecting upper ends of a short inner peripheral wall 30 and a long outer peripheral wall 32, which will be described later, with an annular top wall portion 34, and between the inner peripheral wall 30 and the outer peripheral wall 32. The elastic cylinder portion 44 described later is formed so as to be clamped. In the preferred illustrated example, a plurality of abutment ribs 36 are provided in the upper half portion of the outer peripheral wall 32 corresponding to the clamping portion so as to be bitten into the elastic cylinder portion 44.

  Another function of the sealing member 28 is to seal the gap between the lower part (the soot tube part 54) of the discharge tool 50 and the inner cylinder part 16 (see FIG. 1). Therefore, the inner surface of the inner peripheral wall 30 is an annular seal portion 31 that can seal the lower outer surface of the soot tube portion. The configuration and operation of the annular seal portion 31 will be further described later.

  Further, the seal member 28 has a function of supporting the lower part of the discharge tool 50. The seal member 28 has a rigidity sufficient to ensure this function, and projects an inward flange-shaped locking portion 38 for locking the lower portion of the discharge tool 50 from the lower end portion of the inner peripheral wall 30. The lower end portion of the outer peripheral wall 32 is abutted against the upper surface of the connecting piece 20.

  Further, in the illustrated example, the illustrated annular top wall portion 34 is formed obliquely so as to be substantially flush with the stepped portion 16b with the lower end of the outer peripheral wall 32 abutted against the upper surface of the connecting piece 20. However, this structure can be changed as appropriate.

  The valve member 42 is supported by a horizontal valve plate 48 supported by an elastic cylinder portion 44 that is open at both upper and lower ends, and a plurality of elastic support pieces 46 that protrude inwardly from an intermediate portion in the vertical direction of the elastic cylinder portion 44. The valve member 42 is preferably integrally formed of a soft material such as rubber.

The elastic cylinder part 44 is sandwiched between the upper half part of the cylinder wall between the inner peripheral wall 30 of the seal member 28 and the upper half part of the outer peripheral wall 32, and the lower half part of the cylinder wall is provided on the outer peripheral surface of the fitting cylinder part 22. The liquid leak valve _VL is formed by making it contact detachably.

The valve plate 48 is in contact with the upper surface of the flange-like projections 24, to form a suction valve V _S.

  As shown in FIG. 3, the discharge tool 50 includes a plunger member 52, a syringe member 80, and a flow path restricting member 71.

  The plunger member 52 has a flow restrictor 72 attached in the opening on the lower end side of the top tube portion 54 closed on the upper surface, and an enlarged diameter cylindrical portion 60 from the upper end portion of the top tube portion 54 via an outward flange 58. Is standing up.

  The plunger member 52 of this embodiment is composed of two parts that are integrally molded. That is, as shown in FIG. 3, the plunger member 52 includes a first part 52 a extending from the soot tube portion 54 through an outward flange 58 to a first diameter-expanded cylinder portion 60 a that is a lower portion of the diameter-expanded cylinder portion 60. The second part 52b including the second enlarged diameter cylindrical part 60b which is the remaining part of the cylindrical part 60 is configured. This is to facilitate die cutting as will be described later.

  In the first part 52a, the upper end surface of the soot tube portion 54 is closed by the first top wall portion 56, and the outward flange 58 is extended laterally outward at the same height as the first top wall portion 56. And the first enlarged diameter cylindrical portion 60a is erected from the outer peripheral portion of the outward flange 58. A seal strip 62 is provided around the outer surface of the lower half portion of the first enlarged diameter cylindrical portion 60a. The seal strip 62 in the illustrated example has a skirt shape, but the shape can be changed as appropriate.

  From the top surfaces of the first top wall portion 56 and the outward flange 58, double cylindrical mounting cylinder portions 64a and 64b are erected. These mounting tube portions 64a and 64b are concentric with the soot tube portion 54, the inner mounting tube portion 64a is on the inner side of the inner peripheral surface of the soot tube portion 54, and the outer mounting tube portion 64b is on the soot tube portion 54. They are arranged outside the outer peripheral surface.

  At least one (two in the illustrated example) communication hole 65 is opened at the upper end portion of the soot tube portion 54.

  In the present embodiment, as shown in the exploded cross-sectional view of FIG. 4, a die-cutting hole 65 </ b> A that communicates with the communication hole 65 of the soot tube part 54 and penetrates the first top wall part 56 portion above the communication hole is opened. Yes. The die punching hole 65A is opened between the mounting cylinder portions 64a and 64b. In this way, when the first part 52a of the plunger member 52 is molded, it can be formed by two molds that are divided into an upper side and a lower side. In other words, since it is not necessary to use a horizontal die for forming the communication hole 65, the manufacturing cost of the die can be reduced.

  Further, a lock part 66 for fixing a connecting pipe part 76 to be described later is formed at the lower part of the inner surface of the soot pipe part 54. The illustrated lock portion 66 is a receiving plate portion 66a extending in the circumferential direction along the inner surface of the tube wall at the tip of a plurality of projecting pieces 66b projecting inward from the inner surface of the tube wall of the soot tube portion 54 at intervals in the circumferential direction. It is attached. A liquid flow path is formed between the receiving plate portion 66a and the tube wall of the soot tube portion.

  In the second part 52b, the second enlarged diameter cylindrical portion 60b is suspended from the outer peripheral portion of the second top wall portion 68. The lower end portion of the second enlarged diameter cylindrical portion 60b is fitted to the upper half portion of the first enlarged diameter cylindrical portion 60a. In the illustrated example, a fitting locking rib 61 is provided laterally on the outer surface of the first enlarged diameter cylindrical portion 60a at this fitting location, and the locking rib 61 is fitted on the inner surface of the second enlarged diameter cylindrical portion 60b. Engaging engagement recesses are formed.

  Further, an insertion tube portion 70 is suspended from the inner peripheral portion of the second top wall portion 68, and the insertion tube portion 70 is inserted in a liquid-tight manner between the mounting tube portions 64a and 64b of the first part 52a. I am letting. In the present embodiment, the fitting cylinder portion 70 and the mounting cylinder portions 64a and 64b form a closing means C that seals the die punching hole 65A. However, the structure of the closing means can be changed as appropriate.

  The flow restrictor 71 erected from the upper part of the inner peripheral surface of a flow restrictor plate 72 having an orifice 74 as an injection hole at the center, and the connection pipe 76 is connected to the lock 66. It is stopped. The channel restricting member 71 can be formed of a soft material such as rubber.

  The diameter of the orifice 74 is designed to be small enough to allow the content liquid to be ejected in a stream when the phlegm tube portion 54 and a pump chamber P described later are increased in pressure by the operation of the syringe member 80.

The illustrated flow restricting plate 72 is formed as an elastic valve plate portion 78 by bending the outer peripheral portion upward so as to form a bowl shape as a whole. The elastic valve plate 78 is brought into contact with the inner surface of the soot tube portion 54 to form an auxiliary check valve _VA that opens when the elastic valve plate 78 is further deformed upward from the state of FIG.

  The elastic valve plate portion 78 is bent upward by a negative pressure generated in the soot tube portion 54 when liquid is sucked, and the magnitude of the negative pressure depends on the diameter of the orifice 74. Therefore, the elastic force (or spring constant) of the elastic valve plate 78 is made small enough to cause bending deformation when the syringe member 80 is grasped and lowered according to the diameter of the orifice 74.

The auxiliary check valve V _A serves as a liquid passage from the container body 2 side together with the orifice 74 at the time of liquid suction, and allows quick liquid suction. In the illustrated example, the auxiliary check valve V _A is provided so as to surround the orifice 74 in the center of the flow restrictor plate 72, but this is only a preferred example, and the auxiliary check valve V _A and the orifice 74 are , It may be provided anywhere on the lower end portion of the soot tube portion.

  The syringe member 80 includes a slide cylinder portion 82 that is liquid-tightly fitted to the outer surface of the enlarged diameter cylinder portion 60, and an annular bottom wall portion 86 that is attached to the lower end of the slide cylinder portion 82.

  In the illustrated example, the slide cylinder portion 82 is in liquid-tight contact with only the seal strip 62 of the enlarged diameter cylinder portion 60. This is to reduce the frictional resistance between the slide cylinder part 82 and the enlarged diameter cylinder part 60. However, this structure can be modified as appropriate. Further, a knob portion 84 for picking is attached to the upper end portion of the slide cylinder portion 82.

  The annular bottom wall portion 86 shown in the figure has an inner peripheral portion 86a lower than the outer peripheral portion 86b, and a ring-shaped sliding portion 88 is formed on the inner edge of the inner peripheral portion. The ring-shaped sliding portion 88 is in liquid-tight contact with the outer surface of the tubule portion below the communication hole 65. However, this configuration can be changed as appropriate.

  The space surrounded by the lower surface of the outward flange 58 of the plunger member 52, the outer peripheral surface of the soot tube portion 54, the upper surface of the annular bottom wall portion 86 of the syringe member 80, and the inner peripheral surface of the slide cylinder portion 82 is a pump chamber. P is formed.

  As shown in FIG. 1, the lower half part of the discharge tool 50 is inserted into the storage space S in the inner cylinder part 16 of the lidded container 1 and is detachably attached. Specifically, the container 1 with the lid is discharged via the seal member 28 and the lid member 10 by locking the lower surface of the soot tube portion 54 of the discharge tool 50 to the locking portion 38 of the seal member 28. Supports 50.

  In the present embodiment, a gap G is provided between the inner surface of the large-diameter cylindrical portion 16 a of the lidded container 1 and the outer surface of the slide cylindrical portion 82 of the discharge tool 50. As shown in FIG. 5, when the syringe member 80 is lowered with respect to the plunger member 52, the air in the storage space S can escape to the outside through the gap G, and the large-diameter cylinder portion 16a and the slide cylinder This is to prevent frictional resistance with the portion 82 from occurring. However, this structure can be changed as appropriate.

  Further, in the state of FIG. 1, the lower outer surface of the soot tube portion 54 of the discharge tool 50 is in liquid-tight and air-tight contact with the annular seal portion 31 included in the seal member 28. Since the annular seal portion 31 is brought into airtight contact with the soot tube portion 54, the storage space S shown in FIG. 1 can be shut off from the space inside the seal member 28 serving as a passage for the liquid. Can be performed reliably.

According to the above configuration, when the hook portion 84 is picked and pushed down from the state of FIG. 1, the syringe member 80 descends with respect to the plunger member 52, thereby generating a negative pressure in the pump chamber P. As shown in FIG. The auxiliary check valve V _A and the suction valve V _S are opened sequentially, and the liquid in the container body 2 passes through the suction flow path Ws, the suction valve V _S , the auxiliary check valve V _A and the orifice 74, and the soot pipe part Enter 54. When the collar portion 84 is further lowered, the liquid passes through the communication hole 65 and enters the pump chamber P.

At this time, since the liquid passes through the auxiliary check valve _VA and the orifice 74 at the lower end of the soot tube portion 54 (see FIG. 5), the flow path area is widened, so that the liquid can be sucked smoothly. When the pressing of the flange 84 is released, the auxiliary check valve _VA is closed by elastic restoration.

  Next, when the diameter-enlarged cylindrical portion 60 of the plunger member 52 is gripped and pulled up, the discharge tool 50 is detached from the lid member 10 while the pump chamber P is enlarged. In this state, when the second top wall portion 68 of the plunger member 52 is pushed down with a finger attached to the lower side of the collar portion 84 shown in FIG. 7, the pressure in the pump chamber P is increased. The liquid in the soot tube portion 54 passes only through the orifice 74, and the flow passage area is reduced, so that it is ejected vigorously in a stream shape.

If the plunger member is accidentally pushed after the liquid is sucked into the pump chamber P during the above operation and before the discharge tool 50 is removed from the lid member 10, a liquid leak is caused as shown in FIG. The valve _{VL is} opened, and the high-pressure liquid in the soot tube portion 54 is returned from the orifice 74 to the container body 2 side through the liquid leak valve _VL .
