  Conventionally, it is a pumping pump attached to a container such as a shampoo, which has a whistle inside, and when the head of the pumping pump is pushed down to discharge the shampoo from the container, the whistle assembled to the pumping pump An extraction pump with a whistle is known in which air is sent out and sound is emitted from the whistle.

JP 2001-9330 A

  However, pumping containers with shampoos are often used in places with a lot of moisture, such as in bathrooms. Sound is generated by vibrating air through vibrating pieces called reeds. In the case of the whistle to be made, when the whistle gets wet with water or hot water, the reed does not vibrate and the whistling sound may not be produced even when the pouring pump is operated.

  The present invention solves the above-described problems and provides a whistle-type pump that reliably generates a whistle sound when the pump is operated even when the pump is wet with hot water or the like. Objective.

  In order to solve the above-described problems, the present invention has a whistle-type dispensing pump as follows.

A whistle body that is attached to the upper mouth of the container body and that whips the whistle body that discharges the liquid content from the container body and generates a flow of air when the head body is pressed. A whistle body that does not have a reed and produces sound even when it gets wet by applying airflow to the edge to produce sound.

  An air flow is sent to the whistle body by using an air pump that operates when the head is pressed and sends out air. For example, the piston of the air pump is connected to the head, and when the head is pressed, the piston is pushed down in the cylinder, and an air flow is sent out to the whistle by an air pipe connecting the air pump and the whistle.

  The whistle body is provided with an edge for applying an air flow, and when an air flow is applied to the edge, a vortex flow such as a Karman vortex is formed in the air flow to generate a sound. The shape of the edge is not limited. The whistle body is preferably provided at the head, but may be provided at another location. Furthermore, a sound generation port for transmitting the sound generated by the whistle body to the outside may be opened on the lower surface of the head, or a resonance chamber may be provided continuously with the whistle body.

  Alternatively, an attachment hole may be formed in the head, and a whistle member having an edge may be attached to the attachment hole to constitute a whistle body. In this case, the whistle member may be exchangeable with a whistle member having a different structure. The attachment hole may be formed as a notch as long as the whistle member can be attached. Further, instead of assembling the entire whistle member inside the mounting hole, a part or the whole of the whistle member may be exposed from the outer surface of the head.

  In addition, even if the structure of the whistle member is the same, the attachment position where the whistle member is attached to the attachment hole, the attachment direction, or the like may be changed, thereby changing the structure of the whistle body.

  The whistle pump according to the present invention has a whistle body that generates air by applying an air flow to the edge and does not use the vibration of the lead as a sound source. Sound is reliably generated from the flute by the air flow.

  Therefore, a whistle-pumping pump is attached to a container containing shampoo, etc., so that even when water is splashed during use in the bathroom, the sound of the whistle body can be heard each time the shampoo is poured out. Even if water enters the inside of the whistle body, the air flow sent to the whistle body removes the water from the whistle body, and a normal sound is immediately generated.

  In addition, by opening the sound generation opening for transmitting the sound generated by the whistle body to the outside, it is possible to prevent water from entering the whistle body even when the head is splashed with water. By providing the resonance chamber, the vibration of the vortex generated at the edge resonates, the sound from the whistle body becomes louder, and the sound can be heard more clearly.

  Furthermore, since the structure of the whistle body can be changed by attaching a whistle member having a different structure to the attachment hole, the sound generated from the whistle body can be appropriately changed according to preference.

  An embodiment of a whistle-type dispensing pump according to the present invention will be described.

  FIG. 1 shows an extraction pump 1 with a whistle. As shown in FIG. 4, the whistle pump 1 is assembled to the mouth 52 of the container body 50. When the head 2 is pressed in such a state, the content liquid such as shampoo stored in the container body 50 is stored in the head. It is made to pour out from the spout 4 extended from the part 2. FIG.

  The container body 50 is a container made of synthetic resin or the like, and has a male threaded portion formed on the outer periphery of the mouth portion 52.

  As shown in FIG. 1, the whistle pump 1 has a head 2, a whistle 3 provided on the head 2, a tube 6 extending downward from the head 2, and a tube 6 that can slide freely. From the mounting cylinder 8 held in place, the air pump 14 provided inside the mounting cylinder 8, the pressure feeding part 18 provided in the center of the air pump 14, the suction pipe 10 extending below the pressure feeding part 18, and the like. It is configured.

  The mounting cylinder 8 has an outer peripheral cylinder 12 on the outer peripheral portion, and an internal thread portion to be assembled to the external thread portion of the mouth portion 52 is formed on the inner surface of the outer peripheral cylinder 12. A cylindrical cylinder 17 is provided inside the outer cylindrical body 12. A piston 16 that is slidably in contact with the inner peripheral surface of the cylinder 17 is provided in the cylinder 17, thereby forming an air pump 14.

The piston 16 is made of a soft material, and includes a holding cylinder 32 at the center and a piston piece 33 formed concentrically on the outer periphery of the holding cylinder 32. A plurality of holes through which air passes in the axial direction are formed between the piston piece 33 and the holding cylinder 32. The holding cylinder 32 is cylindrical and is assembled to the outer peripheral surface of the working tube 21 connected to the tube body 6 so as to be slightly movable in the axial direction. The outer peripheral end of the piston piece 33 is formed in a cylindrical shape, and the outer peripheral end is in airtight and slidable contact with the inner surface of the cylinder 17.

  An air valve 20 is attached to the holding cylinder 32 of the piston 16. The air valve 20 includes a valve base 35 fitted to the outer periphery of the holding cylinder 32 and a valve membrane 36 extending in a dish shape from the valve base 35, and the valve membrane 36 operates so as to allow inflow of air into the air pump 14. .

  The inside of the air pump 14 communicates with the whistle body 3 through an air pipe 13 provided inside the tube body 6. More specifically, when the head 2 is pressed down, the working tube 21 is lowered, the presser portion 37 provided on the working tube 21 and the piston 16 are opened, and the air is interposed between the holding cylinder 32 and the working tube 21. The inside of the pump 14 and the air pipe 13 communicate with each other.

When the head 2 is further pushed down and the piston 16 is pushed down through the tube 6, air is sent out to the whistle 3 from the air pump 14 whose volume is contracted. On the other hand, when the head 2 returns upward, the piston 16 is pushed up by the presser portion 37 pushed up by the spring 23, and the piston 16 returns upward. Then, the air pump 14 becomes negative pressure, the air valve 20 is opened, and air flows into the air pump 14 through the gap between the mounting cylinder 8 and the tube body 6.

  In the central portion of the air pump 14, a pumping unit 18 that pumps the content liquid from the container body 50 is provided.

  The pumping unit 18 includes an operating tube 21, two valve mechanisms 22 and 24 provided above and below the pumping unit 18, and a spring 23. When the head 2 is pressed, the operating tube 21 becomes a spring 23. Accordingly, the valve mechanism 24 is closed, the valve mechanism 22 having a ball is opened, and the content liquid stored in the meantime is sent out to the spout 4.

  On the other hand, when the hand is released from the pressing of the head 2, the operating tube 21 is pushed up by the repulsive force of the spring 23, the valve mechanism 22 is closed, and the valve mechanism 24 is opened by the negative pressure generated in the pressure feeding unit 18. The content liquid is sucked from the container main body 50 into the pressure feeding unit 18.

As shown in FIGS. 1 and 4, the whistle body 3 is provided behind the head 2 (on the side opposite to the spout 4). FIG. 2 shows a rear portion of the head 2 as a reference example .

  A mounting hole 5 that opens rearward is formed behind the head 2, and a whistle member 7 is fitted into the mounting hole 5. The whistle member 7 has a cylindrical shape with a wall 42 at the end, and an air hole 9 is formed in the center of the wall 42. The wall body 42 is disposed so as to form a space 15 behind the attachment hole 5 in a state where the whistle member 7 is assembled to the attachment hole 5. Further, an outlet 11 communicating with the air pipe 13 is provided at the back of the mounting hole 5.

In this way, the whistle body 3 includes an outlet 11 provided in communication with the air pipe 13, an air hole 9 provided in the whistle member 7, and a space 15 formed by the whistle member 7 and the attachment hole 5. The sound is generated when the air flow from the air pump 14 flows out of the outlet 11.

  The reason why the sound is generated is that the air flow flowing out from the outlet 11 spreads in the space 15 to form a swirling flow in the space 15 and flows out from the air hole 9 using the edge 44 of the air hole 9 as an edge. It is thought that sound is generated because the air flow forms a vortex behind the edge.

  Since the whistle pumping pump 1 is configured as described above, when the head 2 is assembled with the container body 50 and the head 2 is pressed, the content liquid is poured out from the spout 4 and a sound is generated from the whistle body 3. Since the whistle body 3 does not have a vibrating piece such as a lead, the function of generating sound does not deteriorate even when wet, and it can always generate sound as the content liquid is poured out. it can.

FIG. 3 shows an embodiment of the whistle body 3. In the case of this whistle body 3, a cover 19 is provided on the whistle member 7, and when the whistle member 7 is assembled to the attachment hole 5, the cover 19 is provided behind the head 2, and the sound output 25 is formed on the head 2. Opened on the lower surface of the. The cover 19 is preferably continuous with the outer peripheral surface of the head 2.

  Thereby, in this whistle body 3, even when the cover 19 blocks water and a shower is applied, it is possible to prevent water from directly entering the whistle body 3 from the lateral direction. In addition, since the sound generation opening 25 is opened on the lower surface of the head 2, the sound generated by the whistle body 3 is transmitted to the outside through the sound generation opening 25.

  Further, the whistle member 7 can be removed from the mounting hole 5, and the structure of another whistle member 7 having a different structure, for example, the wall body 42 is changed to change the capacity and shape of the space 15, or the diameter of the air hole 9. Or, the mounting position may be changed and a whistle member having a different structure may be assembled in the mounting hole 5 as appropriate. By replacing the whistle member 7 having a different structure in this way, the tone generated by the whistle body 3 can be changed to a desired one.

  The whistle body 3 is not limited to the structure described above, and may have other configurations as long as the whistle does not have a vibrating piece.
