考案を得たものである。 Conventionally, a commonly available method for taking out a beverage such as a youth drink packaged in a double-layered flexible packaging bag for drinking is to cut out a part of the packaging bag to form an opening. A method of draining the drink from the opening and drinking it has been carried out, but the flexibility of the packaging bag makes opening the bag difficult, and the direction of flow is not determined.
It also has the disadvantage of having poor shape-retaining properties, making it difficult to pour out the liquid.One method to eliminate this disadvantage is to stick a straw with a sharp tip into the packaging bag diagonally from above and suck it up. Although,
From the standpoint of protecting drinks, materials such as strong polyester film, nylon film, or aluminum foil are used for the constituent materials of multi-layer flexible packaging bags used as packaging bags, and are suitable for straws to be pierced. As a result of various experimental studies to solve this problem, it was found that the initial rupture strength of the packaging bag is relatively high due to the slipperiness of the wall surface of the packaging bag, which makes the stickability of the straw poor. The present invention was developed to eliminate this drawback.

なる包装袋である。 Hereinafter, specific examples of the present invention will be explained with reference to the drawings. Polyester film, nylon film,
The inner surface of the single-layer or multi-layer exterior membrane 1 is made of polyethylene or polypropylene, which is selected from various materials such as cellophane, paper, and aluminum foil to impart desired properties such as heat resistance, air resistance, light-shielding properties, and rigidity. The above-mentioned packaging material 3 is formed by bending or stacking two layers using a packaging material 3 laminated with a heat-adhesive resin film 2 such as the one described above, and if necessary, folding it in a mountain shape, for example.
is inserted into the bottom wall 4, and the required periphery is bonded and sealed by heat bonding with the heat bonding part 5 having the appropriate shape and width to form the bag body 6, and the wall surface 7 on one or both sides of the bag body 6 is sealed. This packaging bag has a piercing portion formed by an embossed portion 8 which is embossed with spot-like or band-like unevenness by hot pressing or cold pressing on the upper portion.

The embossment is formed in the upper band that includes the intended location of the straw to be pierced, and the embossment has various shapes such as a grid, dots, and stripes.

ある。 Further, in the present invention, the embossed portion 8, that is, the protruding portion of the straw, can be formed by hot pressing or cold pressing, but if the embossed portion 8 is embossed by hot pressing, The embossing is formed into a sharp shape due to the plastic deformation of the thermoadhesive resin film 2 due to heating during hot pressing, and the exterior film 1 is also formed due to the thermal history caused by heating.
The piercing resistance of the plastic film and thermoadhesive resin film 2 that make up the structure is reduced, and the strength of membrane rupture is also reduced due to the structural shift of the constituent materials due to embossing, which improves the stickability of the straw, making it suitable for use. In particular, those in which a strong stretched film such as a uniaxially stretched film or a biaxially stretched film is disposed on the surface layer of the exterior membrane 1 (for example,
No. 53-129070), the stretching characteristics disappear due to the heat history caused by heating during hot pressing, and the straw has reduced various strengths and has good piercing suitability, which is useful.

でも極めて使用し易い。 In the present invention, a bag body 6 is formed by thermally bonding and sealing a packaging material 3 with a heat-adhesive resin film 2 layered on the inner surface of an exterior film 1 at the required periphery using a heat-adhesive part 5.
Since the straw piercing part is provided on the upper part of the wall surface 7 of the bag body 6 by forming an embossed part 8 having irregularities in the shape of spots or bands, the strength of membrane rupture in the embossed part 8 is reduced by embossing. At the same time, the slipperiness disappears due to the unevenness of the surface formed by embossing, and the tip of the straw engages with the embossed recess, and the piercing force is concentrated in the recess. Even a plastic straw with a sharp point can be stabbed very easily and reliably, and the puncture position can be easily detected not only visually but also with the fingertips, so there is no need to worry about visual impairment. Extremely easy to use even for some people.

ものである。 In addition, in the present invention, the embossed portion 8 is formed only at the planned upper straw piercing position of the wall surface 7 of the bag main body 6, or only in the upper band that includes the straw predicted piercing position, and is formed around the pierced straw. There is no risk of the contents flowing out. Furthermore, when used as a packaging bag, it has an appearance that indicates the insertion position of the straw, thereby increasing the product value.
