Stand-up pouch having cross-seal feature and method of making

摘要

A one-piece flexible-plastic fluid container or pouch (130), adapted for containment of a fluid, is disclosed. The pouch (130) comprises a bottom (135) and a pair of sidewalls (132 and 133) that are unitary with the bottom (135). Each sidewall (132 and 133) includes edge margins disposed transverse to the bottom (135) and an end margin located in distal relation to the bottom (135). The edge margins of one sidewall (132), when joined in a fluid-tight manner to the respective edge margins of the other sidewall (133), define a pair of spaced-apart fluid-tight sideseams (136 and 138). Each sideseam (136 and 138) has a respective end portion (140 and 142) that is opposite the bottom (135). A portion of each sidewall end margin (144 and 146) when joined in a fluid-tight manner to the respective remainder portion (145 and 147) thereof and the sideseam end portions (140 and 142) opposite the bottom (135) when proximally joined together in a fluid-tight manner collectively define a fluid-tight endseam (150). The pouch (130) further comprises a sleeve (137). The sleeve (137) is unitary with the bottom (1352) and the sidewalls (132 and 133); and the sleeve (137) circumscribes the bottom (135). The sleeve (137) and sidewalls (132 and 133) possess sufficient stiffness for enabling the sidewalls (132 and 133) to remain generally upright relative to a horizontal surface when the sleeved, bottom end (134) of the pouch (130) is placed on such a surface. Also disclosed is a method of making the fluid container or pouch (130).
