Embodiment Construction

[0060] Next, the spout-equipped bag 10 according to the first embodiment of the present invention will be described based on the drawings.

[0061] Such as figure 1 As shown, the bag 10 with a spout is constituted by forming a pouch body 20 formed in a bag shape by forming an outer edge sealing portion 21 obtained by thermally welding the outer edges of overlapping films, and attaching a spout to function as a spout. Functional outflow port 30, thereby containing content liquids such as detergent and shampoo.

[0062] Below, based on Figure 1 ~ Figure 3 The respective constituent elements of the spout-equipped bag 10 will be described.

[0063] First, the bottom part is thermally welded between the two main parts by using the two main parts on the front and back sides and the bottom part bent into an inverted V shape, which are made of laminated films, such as figure 1 As shown, the bag main body 20 has an overall shape as a stand-up bag having: an upper edge; a lower edge...

Abstract

The present invention provides a bag with a spout. This spout-equipped bag has an spout attached to an attachment edge portion of a bag main body which has an outer edge seal portion and a pair of flow path control seal portions, the outer edge seal portion having The mounting seal is formed along the mounting edge, and heats the front and back films in a state where the mounting base of the outflow port is disposed between the front and back films of the bag body. The outflow port is installed by welding; the pair of flow path control sealing parts are formed on the inner side of the bag plane direction of the mounting seal part of the outer edge sealing part with a virtual line extending the central axis of the outflow port body On the left and right sides, in a direction perpendicular to the imaginary line, at least one of the flow path control sealing parts on the opposite side of the imaginary line is formed adjacent to the container for containing the content liquid. An unsealed part that is connected to each other.

Description

[0001] This application is a divisional application of the invention patent application with the application number 201780065150.2, the application date is October 18, 2017, and the invention name is "bag with outlet". technical field [0002] The present invention relates to a bag with a spout in which a spout is attached to a bag body.
