Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packaging bag equipped with a pouring tool that can be inserted into the packaging material to take out the contents.

2. Description of the Related Art Packaging bags are widely known in which the contents can be taken out by cutting the packaging material along a thermally bonded part and inserting a pouring tool such as a drinking straw without opening the bag. In this case, if the packaging bag is made of a flexible film-like material, it is difficult to pierce the packaging material with a straw, so a holder that serves both as reinforcement and guidance is provided at the insertion point. It is proposed in Japanese Utility Model Application Publication No. 58-53051.

However, the receiver disclosed in the above-mentioned publication is composed of a flange fixed to the inner surface of the packaging material of the packaging bag and a short tube with a notch that diagonally guides a dispensing tool such as a straw. When inserting a straw, etc. through the packaging material, there is a risk that the contents may leak through the gap between the tear hole and the straw, etc., and fall down the outer surface of the packaging material. There is an inconvenience in that the dispenser must be placed above the contents.

The present invention has been devised in order to solve these problems and provide a packaging bag with a pouring device that allows the contents to be poured in any position without fear of leakage.

That is, the packaging bag with a pouring device according to the present invention includes a receiver provided with a flange at the base end of an insertion tube, and a base end of a pouring tube having a sharp end portion at the tip and fitted into the insertion tube. It consists of a combination of a pouring tool provided with a flange and a discharge pipe extending rearward, and a bag body made of a packaging material having heat adhesive properties on the inner surface, and the receiver has its flange adhered to the inner surface of the packaging material. The present invention is characterized in that the bag is fixed to the inside of the bag.

Then, the sharp end pierces the packaging material, the spout tube is fitted into the insertion tube, and the contents are poured out while the packaging material is strongly held between the flange of the receiver and the flange of the spout tool. It is something to do.

Next, embodiments of the present invention will be described based on the drawings.

In the first embodiment shown in FIGS. 1, 2, 3, and 4 and the second embodiment shown in FIGS. It is constructed by providing a screw 4 in the through hole. In addition, the spouting tool 15 is provided with a flange 12 at the base end of the spouting tube 11, which has a sharp end 13 formed by cutting diagonally and protruding from the tip, and a discharge pipe 14 extending rearward from the flange 12. A packing 16 is stacked on the distal end surface of the spouting tube 12, and a screw that is screwed into the screw 4 of the receiver 3 is formed on the outer peripheral surface of the spouting tube 11. Furthermore, the bag 9 is made by folding the packaging material 7 in half, which is made by laminating the thermal adhesive layer 5 on the inner surface of the exterior material 6, or by overlapping the two sheets and applying heat to necessary parts such as the edges of the overlap. It is configured by forming an adhesive part 8.

Then, the receiver 3 is fixed by thermally bonding the flange 2 to the inner surface of the packaging material 7 using the heat adhesive layer 5 or by bonding it with an adhesive, and is fixed at a predetermined location inside the bag body 9. is fixed to.

In the configurations of the two embodiments described above, the sharp end 13 is applied to the center of the flange 2 of the receiver 3 to pierce the packaging material 7 in that area, and then the spout pipe 11 is screwed onto the screw 4 for pouring. After the flange 12 of the dispenser 15 is screwed in and fixed until it comes into pressure contact with the packaging material 7, the contents are poured out through the pouring pipe 11 and the discharge pipe 14.
The screw may be omitted and the spout tube 11 may be press-fitted into the insertion tube 1 and fixed by being pushed in with strong force.

Next, in the second embodiment, a communication hole 18 is provided at the base end of the insertion tube 1 adjacent to the flange 2, and an inner hole is provided at the base end of the spout pipe 13 close to the flange 12. Inflow hole 20 communicating with 19
is provided, and is configured such that when the pouring tool 15 is fitted into the receiver 3 as described above, the communication hole 18 and the inflow hole 20 overlap. According to this embodiment, by directing the discharge pipe 14 downward and lowering the part where the receiver 3 is provided, most of the contents can be left out through the inflow hole 20 and the communication hole 18 opened at the bottom thereof. It can be dispensed without any

In addition, the receiver 3 and the pouring tool 15 are made of polyethylene,
Consists of molded products of thermoplastic synthetic resins such as polypropylene and polyvinyl chloride. The exterior material 6 of the packaging material 7 may be a single layer of metal foil such as aluminum, a synthetic resin film such as polyester, polyamide, or polypropylene, or a paper material such as cellophane or art paper, or a multilayer film formed by appropriately combining these materials. It is composed of a material that has gas-barrier properties, moisture-proofing properties, light-blocking properties, and sufficient mechanical strength. Furthermore, the thermal adhesive layer 5 is made of polyethylene,
It is composed of a film or coating made of synthetic resin such as polypropylene.

Furthermore, the packing 16 of the pouring tool 15 is unnecessary if the exterior material 6 is made of synthetic resin and has elasticity itself, but it may be made of a non-elastic material such as metal foil or paper. In some cases, it is necessary.

As can be understood from the above description, the present invention includes a dispensing pipe that is fitted into the insertion tube of the holder fixed inside the bag, and a flange that works with the flange of the holder to sandwich the packaging material. Since the dispensing tool is equipped with a dispensing tool, when the dispensing tool is inserted into the receiver with the sharp end of the dispensing tool breaking through the packaging material, the packaging material is strongly pinched by the flanges, thereby preventing the packaging material from being torn. It completely eliminates the leakage of the contents from the gap between the hole and the spouting tube, and it is not only convenient to be able to pour out the bag in any position, but also because the discharge tube protrudes from the rear of the spouting tube. Because of this, the contents can be taken out at a position away from the bag, and even viscous contents can be poured out without the inconvenience of running down the outer surface of the bag. In addition, the receiver is fixed inside the bag by adhering to the inner surface of the packaging material, and the packaging material itself is not processed, so the gas barrier properties and other properties of the packaging material may be impaired. The bag can be stored for a long time without any deterioration or deterioration of the contents.Furthermore, the bag can be formed by the usual method of thermally bonding the overlapping edges of the packaging materials, and the flange of the receiver can be thermally bonded. It is also possible to bond using layers, which is advantageous in terms of manufacturing.
