DESCRIPTION OF THE PREFERRED EMBODIMENTS A first example will be described with reference to the accompanying drawings. In FIG. 1, a container body 1 accommodates a soft bag 3 forming a liquid chamber (liquid storage chamber) 2 therein. Directly, container body 1
May be used as the liquid chamber 2, but the use of the soft bag body 3 is an easy means since it shrinks in accordance with the consumption of the contained liquid and can prevent the intrusion of outside air. This soft bag 3
It is attached to the lower peripheral wall surface of the mouth member 4 attached to the opening of the container body 1 by heat sealing or the like so as not to leak liquid. The mouth member 4 has a piston 5 inside.
The illustrated piston 5 has a separate piston body 6 fixed thereto in order to exert a moderate elasticity and secure a large diameter, but may be an integrally molded product.
A first valve 7 that can be opened upward in the drawing is attached to the piston 5. The first valve 7 serves as an outlet for the liquid from the inner hole 8 communicating with the liquid chamber 2. In addition, the elastic body 9
The cylinder 10 urged upward in the drawing is attached to the piston 5 so as to be slidable in a liquid-tight manner. An elastic annular portion 11 provided solely on the outer peripheral wall of the piston body 6 serves as a sealing sliding contact portion with respect to the inner peripheral wall of the inner hole 12 of the cylinder 10. Further, the cylinder 10 is provided with a valve 13 that can be opened upward in the drawing, similarly to the first valve 7. The second valve 13 serves as an outlet for the liquid that has come out of the first valve 7 into the inner hole 12.

A nozzle body 1 is provided above the cylinder 10.
4 is attached. The illustrated nozzle body 14 includes a nozzle member 15, a liquid flow passage 16 formed in the nozzle member 15, and through which the liquid coming out of the second valve 13 flows.
The small-diameter discharge port 16a communicates with the liquid flow passage 16.
And a film-like member 1 fixed by heat welding to an intermediate portion of the side surface of the nozzle member 15 so as to cover the discharge port 16a.
7. The film-like member 17 is
The periphery of the nozzle member 15 is welded to the middle of the side surface of the nozzle member 15 by melting the periphery (the grid portion is a welded portion in the figure), but the upper portion is not welded, and the non-welded portion 18 is not welded. Has become. This non-welded portion 18 becomes the discharge port portion 19 in the present invention. The non-welded portion 18 is formed by a method such as coating or printing a resin having a higher melting point with respect to heat than the material of the nozzle member 15. Resins for coating and printing include urethane resins, epoxy resins, polyester resins,
A thermosetting resin such as a UV resin is preferable, but another resin may be appropriately selected as long as it has a high melting point. Alternatively, a non-welded portion 18 may be formed by fixing a different material such as a metal foil plate by a method such as bonding. The non-welded portion 18 can be formed in various ways. The film-shaped member 17 is always in close contact with the middle part of the side surface of the nozzle member 15 and shields the discharge port 16a to keep the nozzle body 14 sealed. Non-welded part 18
Are elastically expanded to form the discharge port portion 19 (see FIG. 3).

[0007] Specific examples of the film-like member 17 include a member in which polyethylene is adhered to the lower surface of PET and a member in which PE is attached.
It is preferable to have a two-layer structure such as a structure in which polypropylene is attached to the lower surface of T. In addition, it has a three-layer structure, such as one in which PET is attached to the upper surface of an aluminum foil and polyethylene is attached to the lower surface, and one in which PET is attached to the upper surface of the aluminum foil and polypropylene is attached to the lower surface. Is also good. Furthermore, PET coated with vinylidene chloride
The lower surface of PET, the lower surface of PET coated with vinylidene chloride, the lower surface of PET coated with vinylidene chloride, the lower surface of PET coated with silicon oxide, the lower surface of PET coated with silicon oxide May be used in which a polypropylene is adhered to the resin or a PET whose lower surface is coated with a hot-melt resin. The point is that the upper layer or the intermediate layer of the film-shaped member may be made of a material having a higher melting point with respect to heat than the lower layer, or may be appropriately selected depending on the type of liquid. The material of the lower layer of the film-like member 17 is
It is preferable to use the same material as the material of the nozzle member 15 to be thermally welded.

The film member 17 can be fixed to the nozzle member 15 by a simple method such as fixing with an adhesive. However, depending on the type of liquid, the adhesive and the liquid may be fused. Therefore, it is preferable that the film-like member 17 is fixed to the nozzle member 15 by heat welding using heat or ultrasonic waves in a state where the film-like member 17 is placed on the middle part of the side surface of the nozzle member 15 as described above. A welding horn for heat welding is usually formed by cutting out a portion corresponding to the non-welded portion on the lower surface of the horn so as to prevent unnecessary heat from being transmitted to the non-welded portion. In the configuration of the example, the amount of heat may be appropriately selected, and the film-shaped member 17 may be welded to the nozzle member 15 by a flat welding horn having no cutout on the lower surface. Since the amount of heat is uniformly transmitted to the entire surface of the film-like member 17, this is an effective means for preventing unnecessary shrinkage and wrinkle deformation of the film-like member to be welded.

Next, an example of use will be described. When the top surface 14a of the nozzle body 14 is pressed, the cylinder 10 slides downward in the drawing against the elasticity of the elastic body 9, and at this time, the second valve 13 is opened and the liquid in the cylinder 10 is discharged. The liquid is discharged from the inner hole 12 to the liquid flow passage 16 of the nozzle member 15. Next, the liquid in the liquid flow passage 16 is guided to the discharge port 16a, and the pressure of the liquid causes the film-like member 17 to move.
The non-welded portion 18 is elastically expanded to form the discharge port portion 19, and the liquid is discharged (see FIGS. 3 and 4). Here, the finger is moved upward from below the film-like member 17,
The liquid discharged from the discharge port 19 is wiped off and removed. In this way, by removing the liquid from below in the upward direction, invasion of various bacteria and dirt into the discharge port 19 can be prevented. Note that the opening amount of the discharge port 19 in FIG. 3 is exaggerated for the sake of explanation, but is actually about 0.001 mm.
Here, when the pressing of the nozzle body 14 is released, the film-shaped member 17 is elastically restored, the ejection base 19 is closed again, the ejection port 16a is shielded, and the elastic force of the elastic body 9 is applied. Cylinder 10 slides upward (return)
At this time, the first valve 7 is opened and the inner hole 8 of the piston 5 is opened.
Then, the liquid comes out to the inner hole 12 of the cylinder 10 and the next use preparation is made.

In this embodiment, the non-welded portion is provided above the film-shaped member. However, the non-welded portion may be provided in the lateral direction or in the downward direction. However, in consideration of the possibility of liquid dripping after use, it is preferable to provide the upper portion as shown in the illustrated example. Further, by providing the discharge port portion in the middle of the side surface of the nozzle member as in this example, when removing the discharged liquid, the top surface 14a of the nozzle member 14 of the liquid is removed.
Can be prevented as much as possible, so that the sanitary container can be used for a long time.

[0011]

The discharge container of the present invention is a discharge container provided with a liquid discharge port on the side of the container. The discharge port is provided in the middle of the container, and one part of the discharge port is not provided. Since the film-shaped member as the fixing portion is fixed, and the non-fixed portion is used as the liquid discharge port, a hygienic hermetically sealed discharge container is used.
It can be provided with a simple configuration and at low cost.
