Description

  The present invention relates to a container for containing a highly viscous fluid such as an adhesive including various sealing materials, and a method for assembling the container.

  Currently, examples of containers that contain high-viscosity fluids such as adhesives include containers for high-viscosity fluids disclosed in JP-A-2001-335081.

  The high-viscosity fluid container 15 includes a pouch 16 formed by forming a film-like material into a bag shape, and an extrusion port attached to one end of the pouch 16. The extrusion port has a male screw formed on the outer peripheral surface thereof. An extrusion base 10 having a flange portion 13 attached to the pouch 16 at one end of the cylindrical portion 12 and a male end threadedly engaged with a base end inner peripheral surface of a cone-shaped cylindrical body It is comprised by the extrusion nozzle 11 in which the internal thread to be formed was formed.

The extrusion port base 10 is attached to the pouch 16 and is used as an extrusion port. At the time of attachment, an adhesive layer is formed on the surface of the flange portion 13 of the extrusion port base 10 to be attached to the pouch 16. 14 are laminated and attached to the pouch 16. When the container 15 is used, the inside of the stuck extrusion base 10 is torn and perforated with a suitable stick or the like. Then, a female screw of the extrusion nozzle 11 similarly obtained by resin injection molding is screwed and fixed to a male screw of the extrusion base 10, and the tip of the extrusion nozzle 11 is cut and released at an appropriate position. The container 15 is set on a commercially available extrusion gun or the like, and the contents are extruded and used.
