This inlet tube 40 is coupled with the stem 70 of the dispenser as shown in FIG. 1 to communicate with the dispenser interior space. The nozzle accommodating part 44 is formed in one side of the main body 42, and this nozzle accommodating part 44 communicates with the one side of the inflow pipe 40. As shown in FIG. A nozzle 32 in the form of a short pipe as shown in the drawing is inserted into the nozzle receiving portion 44. The proximal end of the nozzle 32 is opened and is tightly coupled to one side of the inlet pipe 40, and the distal end is provided with a discharge port 30 for discharging contents at the center thereof. Although not shown, a sealing member may be interposed between the proximal end of the nozzle 32 and one side of the inflow pipe 40 to prevent the contents from leaking between the nozzle 32 and the nozzle accommodation portion 44.

The opening and closing rod 34 is installed so that the proximal end is fixed to one side of the inlet pipe (40). Opening and closing rod 34 is disposed in the center line of the nozzle 32 along the longitudinal direction of the nozzle 32, the front end is spaced apart from the discharge port 30 is disposed in the center of the discharge port (30).

As such, the main body 42 itself functions as a pumping button, and as the inlet pipe 40, the opening / closing rod 34, the nozzle accommodating part 44, and the like are integrally injection molded into the main body 42, Components are greatly simplified and manufacturing processes can be greatly reduced.

As shown, between the discharge port 30 and the opening and closing rod 34 is a valve 36 for opening and closing the discharge port 30 in accordance with the discharge pressure of the contents. Preferably, the plate 36 is made of a soft resin material, and opens and closes the discharge port 30 by the elastic force of the material itself. The outer wall of the valve 36 is fixed to the inner wall of the discharge port 30, the inner wall is installed to be in close contact with the tip of the opening and closing rod 34.

It is formed to be integral with the extrusion tube 38 formed by the double injection molding.

More preferably, as shown in FIG. 5, a plurality of protruding jaws 36a protruding toward the opening / closing rod 34 are formed on the inner surface of the valve 36. The protruding jaw 36a is a part elastically contacting the tip of the opening / closing rod 34, and is usually in close contact with the tip of the opening / closing rod 34 to keep the contents airtight, and when the contents are discharged from the opening / closing rod 34. It is pushed out and the discharge port 30 is opened. As shown, a plurality of protruding jaw (36a) is arranged along the circumferential direction of the valve 36, the groove 36b is formed between the protruding jaw (36a). The groove 36b is arranged to be spaced apart from the tip of the opening / closing rod 34 in a state where the protruding jaw 36a is in close contact with the opening / closing rod 34.

According to the structure of the valve 36, the projection jaw 36a presses the tip of the opening and closing rod 34 to increase the reliability of the airtightness of the contents, and at the same time between the valve 36 and the tip of the opening and closing rod 34. In the groove (36b) forms a fine slit to balance the pressure between the air and the discharge unit. Therefore, it is possible to ensure stable discharge of the contents even at a low discharge pressure while maintaining the airtightness of the contents contained in the dispenser at a reliable level.

Preferably, the tip of the opening and closing rod 34 is formed in a dome shape as shown in Figs. 4A and 4B. As such, when the tip portion of the opening and closing rod 34 is formed in a dome shape, the contact area between the opening and closing rod 34 and the valve 36 may be minimized to ensure a flexible discharge operation. In place of this, the front end of the opening and closing rod 34, as shown by the hidden line in FIG. This step 35 can minimize the contact area with the protruding jaw 36a and ensure stable contact.

As shown in FIG. 4A, a soft synthetic resin is injection molded on the inner wall surface of the nozzle 32 to form an extrusion tube 38. The inner circumferential edge of the extruded tube 38 is arranged to be spaced apart from the outer circumferential edge of the opening and closing rod 34. The tip end of the extruded tube 38 is reduced to surround the inner wall of the discharge port 30, and the reduced diameter portion thus formed forms the valve 36.

The extrusion tube 38 and the valve 36 may be insert injection molded into the nozzle 32, but are preferably double injection molded together with the nozzle 32 to form an integral part with the nozzle 32. do. In the discharge unit of the present invention, the nozzle 32 is assembled to one side of the main body 42 to constitute the entire discharge unit. More preferably, the nozzle 32 is also integrally injection molded together with the main body 42, and the extrusion tube 38 and the valve 36 are double injection molded inside the nozzle 32. Thus, the entire discharge unit forming the pumping button can constitute a single part. This will greatly simplify the entire component of the dispenser, as well as significantly reduce manufacturing processes and manufacturing costs.

Referring to Figure 4a and 4b will be described the operation relationship of the discharge unit of the present invention.

Referring to FIG. 4A, when the discharge unit is pressed against the dispenser as shown by the arrow in FIG. 4A, the contents inside the dispenser are pumped into the inlet pipe 40. And it is supplied to the nozzle 32 by the discharge pressure of predetermined intensity. At this time, the discharge port 30 is opened while the valve 36 closing the discharge port 30 is turned outward by the discharge pressure of the content, and the content is discharged to the outside of the discharge port 30 as shown.

Then, when the external force applied to the discharge unit is released, as shown in Figure 4b, the discharge unit is raised and returned to the original position, the discharge pressure applied through the nozzle 32 is released. Therefore, the valve 36 made of a soft resin material is restored by the elastic force of the material itself, and close to the tip of the opening / closing rod 34 as shown in FIG. 4B to close the discharge port 30.

The discharge unit of the present invention and the dispenser having the same as described above in the structure of the discharge unit for opening and closing the discharge port 30 in accordance with whether or not the pumping of the contents, penetrates the inside of the nozzle 32 but is fixed to one side of the discharge unit The opening / closing rod 34 and the plate | plate 36 elastically supported by the front-end | tip part of this opening-and-closing rod 34 are comprised so that the discharge port 30 may be opened and closed by the discharge pressure of the contents. Therefore, the discharge port 30 can be closed more reliably by the valve 36 which is elastically in close contact with the opening / closing rod 34, and unlike the prior art, it is necessary to operate the opening / closing rod 34 by a separate movable means. There is no very simple structure to enable the opening and closing of the discharge port (30).

In particular, the present invention opens and closes the discharge port 30 by the opening and closing rod 34 penetrating the inside of the nozzle 32 and the valve 36 elastically pressurizing the tip circumference of the opening and closing rod 34, thereby the contents inside the dispenser. While keeping the airtight, the valve 36 can be easily pushed out even at a low discharge pressure, thereby ensuring a stable discharge operation. Furthermore, by providing a plurality of protrusions 36a on the inner surface of the valve 36, when the protrusions 36a press the tip of the opening / closing rod 34, the groove 36b between the protrusions 36a opens and closes. There is a predetermined gap between the 34 and the more stable discharge operation can be ensured.

Another technical advantage of the present invention is that by excluding the movable structure of the opening and closing rod 34, the opening and closing rod 34 can be injection molded integrally with the body 42, the extrusion tube 38 and the valve 36 By double injection molding together with the nozzle 32, the entire component constituting the discharge unit may be two components of the main body 42 and the nozzle 32, or a single component of the main body 32 in which the nozzle 32 is integrally formed. Is composed. As a result, the number of components of the dispenser is drastically reduced, the manufacturing process can be reduced, and the manufacturing cost can be greatly reduced.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the technical field of the present invention without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.
