The present invention relates to a pouch for packaging that can hold beverages, herbal medicines, and the like, and relates to a pouch for packaging and a straw that can be used for the pouch, which is safe and easy to manufacture even if the straw is accommodated.

There are many ways to store liquid substances such as beverages and herbal medicines, and among them, packs or pouches using synthetic resin sheets are used to package beverages or herbal medicines. In general, a pouch uses a method of sealing two sheets of synthetic resin sheets together by fusion and sealing the edges by using high frequency or heat. The pouch can completely block the contents until it is opened, and there is an advantage that the liquid material can be easily packaged even with a simple facility because of easy handling and manufacturing.

In general, pouches are packed with liquid materials, so users usually use straws to eat the packaged liquid. Currently, products mainly attaching straws to the outside of pouches, but some pouches with built-in straws are also disclosed.

In Japanese Patent Laid-Open No. 8-337255, a straw is accommodated in a pouch for use and storage of a straw. The user can withdraw the straw by opening the pouch, but it can be difficult to find the straw in the drink because the straw can move within the pouch, and it can be unsanitary because a portion of the hand can touch the drink to find the straw. have.

In Japanese Utility Model Publication No. 6-42696 (published on June 1, 1994), fusion forms a space for storing straw in the pouch, and the straw is stored inside. However, it is necessary to prepare a complex fusion mold to store the straw, there is a disadvantage that it is difficult to precisely adjust the position even during every fusion process.

In Korean Utility Model Publication No. 1984-14739, a straw is fixed to one side of the inside of the pouch. However, adhesive is used to fix the straw and adhesive is used to bond the straw. When such a pouch is stored in a hot content such as a herbal medicine or a retort food, there is a problem in that it can not be used with confidence because the adhesive component may be mixed in the content. Of course, it is possible to use an adhesive that is harmless to the human body, but the adhesive of such a property is very rare and expensive, which can increase the cost and still cannot solve the problem of melting at high temperatures.

One object of the present invention is to embed a straw in the pouch, as in the conventional straw built-in pouch, and to provide a packaging pouch and straw for embedding the straw in a constant position in the pouch, and not using an adhesive or the like.

Another object of the present invention is to provide a pouch for packaging and a straw that can be easily mounted and packaged in the manufacture of the pouch.

Another object of the present invention is to provide a straw which can be simply fixed in a pouch and can be usefully used for other purposes as well.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, a liquid packaging pouch includes a pouch body for packing a liquid material and a straw fixed to one side of the pouch body. The pouch body consists mainly of two sheets of plastic and is fused along the rim using heat or high frequency. The straw is fused together with the plastic sheet when the plastic sheet is fused. To this end, the straw includes a fusion piece that provides a fusion surface on the side of the guide tube and the guide tube. The fusion piece of straw can be fused together between fusion of the plastic sheet, and because the straw is fixed by fusion, even when handling relatively high temperature contents, it is possible to prevent strange mixing of the human body. The fusion piece may be formed of the same material as that of the induction pipe through a process such as injection or extrusion, but may be formed of another material.
