Abstract

PROBLEM TO BE SOLVED: To allow air to be discharged from one of ports when contents are filled from the other port by sealably providing an ejection port and a filling port separately which pass from a lower face of a joint through an upper face to protrude on the upper face. SOLUTION: The pouch plug 10 comprises an ejection port 12 and a filling port 13 which pass from a lower face of a joint 11 through an upper face to protrude on the upper face which are separately provided to be sealable. In order to seal the ejection port after filling contents, a detachable cap may be attached normally with convenience at the time of use considered, or a mouth may be sealed with a sealing sheet (an aluminum foil/sealant resin layer, for example) and then the cap is attached. To seal the filling port, the sealing sheet is normally put over and heat-fused by heat-sealing, but it may be sealed by the cap if necessary. The plug is prepared by injection molding using thermoplastic resin such as polypropylene and polyethylene.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plug for a pouch to be joined to an opening of a pouch (a bag-like flexible container made of a single layer or a laminated film).

[0002]

2. Description of the Related Art Conventionally, pouches used for liquid contents such as medicines, soft drinks, liquid detergents and seasonings are provided with, for example, Japanese Utility Model Application Laid-open No. 2-22-2.
As described in, for example, Japanese Patent No. 1399, there has been known a pouch with a plug in which a plug having a mouth and a conduit hanging down in a container is fixed to an opening.

[0003]

However, in the above-mentioned conventional pouch with a plug, after filling the contents from the mouth of the plug, a cap is attached to the mouth or an aluminum foil is attached to the mouth. After attaching the cap, it was sealed by attaching the cap, but because the diameter of the mouth of the plug is small, the amount of air discharged from the pouch is small when filling the contents, and the filling speed is increased. There was a problem that could not be done.

The present invention has been made to solve the above-mentioned conventional problems. When filling a pouch with contents, the filling speed can be increased, and the amount of residual air in the pouch is reduced. Is provided.

[0005]

Means for Solving the Problems A first invention of the present invention is:
As shown in FIG. 1 (a), this is a spigot to which an outer peripheral surface of a joint (11) is joined and attached to an opening of a pouch (20). A pouch plug (10) characterized in that a projecting spout (12) and a filling port (13) are separately provided so as to be sealable.

Next, a second invention of the present invention is shown in FIG.
As shown in the figure, the joint (1) is inserted into the opening of the pouch (20).
1) A spout which is attached to the outer peripheral surface of 1) and is attached to the spout from the lower surface of the joint to the upper surface, and is capable of sealing a spout (12) and a filling port (13) projecting to the upper surface. Separately,
A pouch plug (10) characterized in that a conduit (14) communicating with the spout and having a through-hole (15) above is vertically provided on the lower surface.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The pouch plug of the present invention is shown in FIG.
As shown in FIG. 2 (a) and FIG. 2 (a), the outer peripheral surface of the joining portion (11) of the plug is joined to the opening of the pouch (20) by heat fusion usually by a heat sealing method or the like. In addition, a plug is formed and attached to the opening of the pouch by forming a seal portion (21). The plug is made by injection molding using a thermoplastic resin such as polypropylene or polyethylene.

As shown in FIG. 1A, the structure of the pouch plug (10) according to one embodiment of the present invention penetrates from the lower surface of the joint (11) to the upper surface and projects to the upper surface. The spout (12) and the filling port (13) are separately provided so as to be sealable. The method of sealing the spout after filling the contents is
Usually, a detachable cap is attached in consideration of convenience at the time of use, or a cap is attached after sealing a mouth portion with a sealing sheet (for example, an aluminum foil / sealant resin layer). . In addition, the method for sealing the filling port portion is generally a method in which a sealing sheet is covered and heat-sealed by a heat sealing method for sealing, but if necessary, sealing may be performed with a cap. .

Further, as shown in FIG. 1A, the structure of the plug for a pouch (10) according to another embodiment of the present invention penetrates from the lower surface of the joint portion (11) to the upper surface and is formed on the upper surface. A projecting spout (12) and a filling port (13) are separately provided so as to be sealable, and a conduit (14) communicating with the spout and having a through-hole (15) above is vertically suspended on the lower surface. It is to establish. The method of sealing the spout and filling port after filling the contents is the same as the method described above.

The method of filling the contents into the pouch (20) to which the plug (10) for a pouch (10) of the present invention is attached is shown in FIG.
(A) and as shown in FIG.
The operation is performed with the filling port (13) opened, and when the contents are filled from the filling port, the air in the pouch is discharged from the spout. For this reason, the filling state is performed smoothly,
The filling speed of the contents can be increased. Further, the amount of residual air in the pouch after filling can be reduced. In addition, the plug (10) for a pouch of the present invention in which the conduit part (14) shown in FIG. 2 (a) hangs in the pouch (20).
When filling the contents, after the tip of the conduit portion is immersed in the contents, the air in the pouch passes through the through hole (15) provided above the conduit portion, and the spout (12). ).

When the contents are to be filled by using the conventional filling system as it is, FIGS.
As shown in (b), the spout (12) and the filling port (13) are opened, the contents are filled from the spout, and the air in the pouch is discharged from the filling port.

When the contents are used, the pouch equipped with the plug for a pouch according to the present invention has a flexibility by removing a cap or a sealing sheet and opening a spout to open the spout. The body of the pouch is pressed by hand, and the contents are discharged from the spout and used.

[0013] The pouch may be a laminated film or a laminated film according to the intended use comprising a polypropylene film, a polyethylene film, a polyethylene terephthalate film, a nylon film, an aluminum foil, a vapor-deposited film, a vinylidene chloride coated film, an ethylene-vinyl alcohol copolymer resin film and the like. It is produced using a single-layer film, and can take various forms such as a square flat pouch, a standing pouch, and a gusset pouch.

[0014]

The pouch equipped with the plug for a pouch of the present invention has a spout and a filling port separately, and when the contents are filled from either one of the ports. In addition, since the air is discharged from the other opening, the filling speed of the contents can be increased, and the amount of air remaining in the pouch can be reduced.

The pouch equipped with the plug for a pouch of the present invention can be filled with the contents from the spout, so that the conventional conventional filling system can be used without any change.
