DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a branch type pouch made of a plastic film, having a branch portion provided on a side wall of a pouch body and having a spout and a handle at the branch portion.

[0002]

2. Description of the Related Art A pouch made of a plastic film is sealed with a gusset made of another film at the bottom, and the width of the bottom of the pouch is enlarged to provide a standing pouch having a self-supporting property, or a flat pouch having no gusset. Pouches are widely used as containers for beverages, retort foods, detergents, cosmetics, and the like. Also, a pouch in which a branch is provided on a side wall of the pouch and a spout for contents is formed in the branch is also known. (JP-A-10-218199, etc.)
On the other hand, it is also known that a handle is formed by cutting or punching a heat seal portion on the top of a flat pouch. In such a flat pouch, the contents are filled from the bottom opposite to the top of the pouch on which the handle is formed, and after filling, the bottom of the pouch is heat-sealed.

[0003]

However, in the case of a standing pouch, since the filling of the contents is performed from the top of the pouch, in order to improve the convenience of the standing pouch, it is necessary to form a handle on the top of the pouch. The following problem occurs in the step of filling the contents. (1) As shown in FIG. 6, when the handle 6 is formed on the top of the pouch 21 in advance, the filling port 7 for the contents is provided.
(It becomes a spout at the time of pouring), and the filling efficiency is reduced. (2) If the handle is formed in the heat seal portion on the top of the pouch after filling the contents, a significant modification of the filling system is required, and the conventional production line cannot be used.

On the other hand, when a handle is formed on a flat pouch by slitting or punching, the inner volume is reduced by the amount of the packaging material used to form the handle, as compared to a pouch having the same outer dimensions without a handle. For this reason, if it is attempted to form a handle while maintaining the internal volume before forming the handle, it is necessary to increase the outer size of the pouch by the amount of the packaging material at the handle portion. In this case, the size of the distribution box needs to be changed, which increases the distribution cost. Further, there is a problem that the area at the time of display at the store is increased, and the storage property is deteriorated. Accordingly, an object of the present invention is to provide a branched pouch with a handle that solves such a problem and is easy to carry and pour out contents.

[0005]

In order to solve the above-mentioned problems, the present invention employs the following configuration. 1. A branch-type pouch having a branch portion formed on a side wall of a pouch body, wherein a spout and a handle are formed in the branch portion. 2. 2. The branch-type pouch according to 1, wherein a spout is provided on one side of the branch portion and a handle is formed on the other side. 3. 2. The branch-type pouch according to 1, wherein a spout is provided at a central portion of the branch portion, and handles are formed on both sides thereof. 4. The branch-type pouch according to any one of claims 1 to 3, wherein the handle is formed by slitting or punching. 5. The branch type pouch according to any one of claims 1 to 4, wherein the branch portion is fixed to a side wall of the pouch body. 6. The branch-type pouch according to any one of claims 1 to 5, wherein an easy-opening portion is provided near a tip end of the spout. 7. 7. The branched pouch according to any one of 1 to 6, wherein the pouch is a standing pouch.
