A liquid container with a spout is disclosed. A composite sheet for the container body comprises an innermost layer of a low-smelly and low-adsorbent resin and an outermost layer of a polyolefine resin. A sealing film comprising a liquid-contacting layer and a sealing layer both made of the low-smelly and low-adsorbent resin seals a spouting hole in the container body from inside the container body. The container body and the spout sandwich a connecting film and a spout-attached film. The connecting film has a hole in alignment with and adjoining the hole in the container body. The connecting film comprises an innermost layer of a polyolefine resin and an outermost layer of the same resin as the innermost resin of the container body. The connecting film is heatsealed to the outermost layer of the container body. The spout-attached film has a hole in alignment with and adjoining the hole in the container body. The hole in the spout-attached film has a smaller diameter than the hole in the container body. The spout-attached film comprises an outermost layer of a polyolefine resin and an innermost layer of the same resin as the innermost layer of the container body. The spout-attached film is heatsealed to an area between the connecting film and the sealing film so that the edge of the rear hole in the spout-attached film is positioned on a portion of the outermost layer of the sealing film adjoining the hole in the container body.

Liquid container with spout

A process for producing a liquid-container material that includes a thermoadhesive resin film, a substrate sheet having a thin-film layer of an inorganic compound, such as a silicon oxide, and a paper substrate. The thermoadhesive resin film is formed by melt-extruding a thermoadhesive resin from an extruder die, and then cooled to a temperature at which the thermoadhesive properties inherent in the thermoadhesive resin film can be retained and at which no crack is produced in the thinfilm layer of an inorganic compound when the thermoadhesive resin film is laminated to the substrate sheet. The cooled thermoadhesive resin film is laminated to the substrate sheet to form a laminate, which is then laminated to the paper substrate. The thermoadhesive resin film may preferably include a non-adsorptive resin layer and a thermoadhesive resin layer. In this instance, the non-adsorptive resin layer is so provided as to be on the outside of the liquid-container material.
