BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid spout used for a liquid container containing a liquid having a relatively high viscosity, for example, a concentrated juice, a syrup, an adhesive, an ink and the like.

[0002]

2. Description of the Related Art Conventionally, various types of liquid containers have been used, and as shown in FIG.
A bag-in-box type liquid container is also used in which a flexible bag 2 made of a plastic sheet or the like is accommodated therein, and a liquid 3 is accommodated in the bag 2. The liquid container is usually provided with a spout 4 for taking out the liquid. The spout 4 generally includes a spout body 4a bonded to the bag 2 and the spout body 4a.
And a cap 4c whose upper end is closed by a thin membrane 4d, if necessary. Such an inner plug 4c is used when the spout 4 is set downward or sideways.
That is, the liquid container usually connects the spout 4 to a connector connected to the pump, and takes out the liquid inside through the connector. As shown in FIG. 6, the connector 6 is arranged at a fixed position and upward. In such a case, it is necessary to remove the cap of the spout 4 and connect the spout 4 to the connector 6 with the spout 4 facing downward, so that the liquid 3 inside does not flow out of the spout 4. The inner plug 4c is provided at the end, and when connected to the connector 6, the tip 6a of the connector 6
Pierced the membrane 4d and opened it.

[0003]

However, in such a configuration, the inner plug 4c must be used to prevent the liquid from flowing out while connecting the spout 4 to the connector 6 with the spout 4 facing downward. Membrane 4 in inner stopper 4c
Since d is attached, the manufacturing process is complicated and there is a problem that the cost of the spout increases.

The present invention has been made in view of such a conventional problem, and has as its object to provide a liquid spout that can be manufactured at low cost.

[0005]

The liquid outlet of the present invention is
A spout body attached to a container containing the liquid, and a cap that is detachable from the spout body, and has a small area that allows the highly viscous liquid to flow slowly into the spout body. Elastically deformable complex to form pores
The number of tongue pieces is provided .

[0006]

In the liquid spout of the above construction, when the spout is capped off and the spout is downwardly connected to the connector, the liquid tends to flow through the spout. Due to the small passage area, the viscous liquid flows slowly through the pores, so that in the short time before the spout is connected to the connector, it hardly flows out of the spout, and therefore, flows around the perimeter. Can be connected to the connector without contamination with liquid. And after connecting to the connector,
The liquid inside the container can be sucked and discharged through the pores.

Furthermore, as described above, since the formation of the pores between the elastically deformable plurality of tongues, a plurality of tongue pieces when sucking and discharging the liquid inside the container attraction As a result, the pores are deformed, the opening area of the pores is enlarged, and the suction and discharge of the liquid are facilitated. If the spout is connected to the connector by using a spout with a tip deep in the spout and elongated so that it can be inserted to the tongue, Since the tip of the tongue penetrates deeply into the spout and pushes the tongue piece inward to increase the opening area of the pore, the liquid can be easily sucked and taken out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention shown in the drawings will be described below. FIG. 3 is a schematic cross-sectional view showing a bag-in-box type liquid container provided with a liquid spout according to an embodiment of the present invention, wherein 1 is a box made of cardboard or the like, and 2 is a flexible container constituting a liquid container. 3 is a highly viscous liquid, for example, ink, contained in the bag 2, and 10 is a liquid outlet according to the embodiment of the present invention.

FIG. 1 is a schematic sectional view of the spout 10 and FIG.
Is a schematic plan view showing the spout 10 with a cap removed. The spout 10 is a spout main body 11 bonded to the bag 2.
And a ring 12 which is screw-engaged with the base of the spout body 11 and a cap 13 which is screw-engaged with the tip of the spout body 11. The spout body 11 has a flange portion 11a for bonding to the bag 2 and a ring 1 on the outer peripheral surface.
Large-diameter portion 11b having a male screw for screw-engaging 2
A small-diameter portion 11c having an external thread for screw-engaging the cap 13 on the outer peripheral surface, and a number of tongue pieces 11d formed to protrude into a liquid passage formed on the inner surface of the small-diameter portion 11c. ing. The tongue piece 11d is thin so as to be easily elastically deformed, for example, is formed to have a thickness of about 0.4 mm, and has a size capable of forming a small pore 14 between these tongue pieces 11d. . Here, the size of the pores 14 is determined so that the highly viscous liquid 3 contained in the bag does not suddenly flow out when the spout 10 is directed downward. That is, as shown in FIG. 4, when the spout 10 is turned downward, the liquid inside flows down while slowly forming the droplets 3 a from the pores 14, and flows out of the spout 10. The droplet 3a is discharged from the spout 10
It takes about 2 to 3 seconds to flow to the outside. For example, when handling ink having a viscosity of about 50 to 400 poise as a liquid, the size of the pores formed by the plurality of tongue pieces 11d is such that the diameter of the central portion is 1 to 4 mm, and the diameter of the central portion is radial. It is preferable that the width of the extending groove portion is about 0.1 to 2 mm.
The spout body 11 having the above configuration is integrally formed by injection molding of a resin such as polyethylene.

In FIGS. 1 and 2, the bag 2 is a spout main body 1.
It is bonded to the lower surface of the first flange portion 11a by heat sealing or the like. The bag 2 may be bonded to the upper surface of the flange 11a. The ring 12 has a flange portion 12a for pressing against the outer surface of the box 1 and the flange portion 12a.
A knob portion 12b formed at an appropriate interval from
This ring 12c has a reinforcing rib 12c and the like.
Outlet body 1 that makes the box project from the inside of the box 1 to the outside
By screwing the box 1, the box 1 is sandwiched between the flange 11 a of the spout main body 11 and the flange 12 a of the ring 12, and the spout main body 11 can be firmly fixed to the box 1. This ring 12 is also made by injection molding of resin. The cap 13 is also made by injection molding of resin.

Next, a method of using the spout 10 having the above structure will be described. The bag 2 is adhered to the flange portion 11a of the spout body 11, the spout body 11 is protruded from the inside of the box 1 to the outside, and a ring 12 is screwed on the spout 2 so that the spout 2 as shown in FIG. 10 is fixed to the box 1. Next, a filling nozzle is connected to the spout body 11, and the contents (liquid) are injected into the bag 2 through the spout body 11. At this time, the liquid flows into the inside through the fine holes 14 between the tongue pieces 11d of the spout body 11, and further deforms the tongue pieces 11d by the liquid pressure at that time to increase the opening area of the fine holes 14. Thereby, quick filling of the liquid becomes possible. When the filling nozzle is shaped so that its tip is deep inside the spout body 11 and elongated so that it can be inserted up to the tongue piece 11d, the filling nozzle is used as the filling nozzle 1
When connected to 1, the tongue piece 11d can be pushed open by the nozzle tip, thereby increasing the opening area of the pores 14,
Quick filling becomes possible. After filling the liquid, the cap 13 is attached to seal the spout main body 11, and transportation and storage are performed in that state.

Next, in using the liquid container,
The cap 13 of the spout 10 is removed, and the spout main body 11 is removed.
Then, the connector connected to the pump is connected, and the pump sucks and takes out the liquid inside. At this time, depending on the device that uses the liquid container, the connector may be provided upward at a fixed position. In this case, as shown in FIG. 4, the liquid container and the spout 10 are directed downward, and the connector 16 is engaged with the upwardly facing connector 16 from above. here,
When the spout 10 is turned downward with the cap removed, the liquid inside tends to flow out through the pores 14 of the spout. However, since the passage area of the pores 14 is small, the liquid is
Flows slowly, and hardly flows out of the spout in a short time until the spout 10 is connected to the connector 16. Thus, the spout 10 can be connected to the connector 16 without polluting the surroundings with the liquid. After the connection to the connector 16, the liquid in the liquid container is sucked and taken out by the pump connected to the connector 16. Also at this time, the tongue piece 11d forming the fine hole 14 is bent downward by the suction force of the pump, the area of the fine hole 14 is enlarged, and the liquid 3 inside is well sucked and discharged. If the tip of the connector 16 is extended deeply into the spout and inserted into the tongue piece, the tip of the connector is deepened into the spout when the spout is connected to the connector. It is preferable because it penetrates and pushes the tongue inward to increase the opening area of the pores to facilitate suction and removal of the liquid. In the above description, the case where the spout 10 is connected to the connector 16 with the spout 10 facing downward has been described. However, the spout 10 is extremely suitable not only when the spout 10 is facing down but also when the spout 10 is connected to the connector sideways or obliquely downward. .

In the above embodiment, the spout main body 11 is fixed to the box 1 by the ring 12, but the ring may be omitted and the spout main body may simply be projected outside the box 1. . Further, in the above embodiment, the case where the spout is attached to the bag-in-box type liquid container is shown, but it goes without saying that the spout of the present invention may be attached to a liquid container other than this type.

[0014]

As described above, the liquid spout of the present invention can be elastically deformed so as to form pores in the spout body that allow the highly viscous liquid to flow out slowly.
When a plurality of tongue pieces are provided, when the spout is connected to the connector with the spout facing down or sideways, it is difficult for the liquid to flow out from the pores of the spout, and
The liquid does not leak out from the mouth and does not stain the surrounding area , making it easier to connect the spout to the connector.
Also, when aspirating and discharging liquid, multiple tongues deform
The pores are enlarged and can be easily sucked and discharged,
Further, since the spout body can be manufactured by integral molding of resin, it has an effect that it can be manufactured at extremely low cost.
