Stand type beverage shape pouch {STAND-TYPE LIQUID STORAGE SHAPED POUCH}

The present invention relates to a stand-up drink-shaped pouch, and more particularly, to a stand-up drink-shaped pouch whose structure is changed to facilitate injecting contents into a discharge port having a predetermined shape.

In general, pouches are widely used for packaging food and the like.

In particular, in simple ready-to-cook foods, the pouch enables the contents to be stored for a long time without deterioration, and the withdrawal for consumption of the contents can also be easily achieved by simply cutting the pouch, so it is widely used for packaging various foods. .

In recent years, various foods have been provided as disposables, and accordingly, the use of pouches is increasing. In particular, in order to preserve and maintain the taste, aroma, and other chewing sensation of solid foods, solid foods and filling water are accommodated in pouches together. are often packaged.

Unlike glass bottles or cans, these pouches are made of a soft material and have a variable volume, are lighter in weight than glass bottles or cans, and are easy to carry. Due to the advantage of being able to store the storage for a predetermined time without consuming it at once through the opening and closing of the storage device, its use has recently been increasing.

Usually, a pouch is made by overlapping two films facing each other on the front and back sides, and then bonding the two films in the required area using a heatseal method. It is a trend that most of them are manufactured by an automated process that continuously processes the entire process from through to final rewinding in batches.

Recently, cases in which the pouch is manufactured in the form of a shaped pouch (Thompson pouch) having a certain three-dimensional shape and sold on the market are gaining popularity.

This shape pouch can be divided into a stand-type pouch and a non-stand-type pouch. In particular, in the case of a stand-type pouch, the process of inserting the contents is on the exit side, and the narrow shape problem on the exit side (for example, There is a difficulty in the manufacturing process due to the problem of inserting the beverage through a small space such as the mouth of a beverage bottle).
