TH6090B - Flexible pouch that forms contoured edges for easy liquid pouring. - Google Patents

Abstract

Minimal self-standing flexible pouches are made of one plastic sheet welded together to form a closed internal chamber for liquid storage. The perimeter of the wall material forms a border around the outline and bonds together to form a closed pouring spout at one corner of the bag. The outline of the spout is defined by a rim around the outline of the plate sealing in close proximity. With the corner of the bag, the spout for pouring liquid can be opened by cutting the corner of the bag at an angle. The periphery that is bonded together generally has a square border around the outline. Except for the part that makes the curve concave inward corresponding to the part that is concave into the wall material. in which the partially concave part is used as the outline of the spout This concave section has a maximum height greater than the maximum depth. When measured transversely with the direction measured along the height. In addition, the indentation may begin at the top edge of the bag or at a point along the side that extends from the top edge. The portion of the weld along the top edge of the bag. and the weld portion along the edge of the indentation determines the outline of the open pour spout. The open spout must be inserted into the open neck of the container to be filled with liquid.
