Blow-molded plastic infusion container

摘要

A bottle-type blow-molded plastic infusion container that can be set in an upright position. When liquid is discharged from the container, almost no dead space occurs in shoulder and bottom portions (required amount of air to be placed in the container to remove residual liquid is less). The blow-molded container has a mouth section (1), a neck section (2), the shoulder section (3), a barrel section (4), and the bottom section (5). The barrel section (4) has a pair of broad side faces (41, 41) and a pair of narrow side faces (42, 42). The bottom section (5) is formed in a shape symmetrical about a longitudinal axis of the bottom section (5) and bent inward in a V shape. Further, the shoulder section (3) has a pair of broad side faces (31, 31) and a pair of narrow side faces (32, 32). In the narrow side faces (32, 32) are formed grooves (33, 33) symmetrical about a longitudinal axis and bent inward in a V shape.

主权项

1. A blow-molded plastic infusion container comprising:
a mouth; a neck having a first end and a second end, the first end being connected to the mouth; a shoulder extending downward and outward from the second end of the neck; a barrel connected to the shoulder; and a bottom, having a hanging member, wherein said barrel has a pair of wide sidewalls and a pair of narrow sidewalls, and said bottom is formed into a V-shape bent inwardly and symmetrically with respect to the long axis of the bottom, wherein the shoulder has a pair of wide sidewalls and a pair of narrow sidewalls, said narrow sidewalls of the shoulder being provided with V-shaped groove portions bent inwardly and symmetrically with respect to the long axis, wherein the V-shaped groove portions provided on the narrow sidewalls of the shoulder extend to the second end of the neck, wherein the blow-molded plastic infusion container is structurally configured to be thinned and flattened by the discharge of infusion contained in the blow-molded plastic infusion container, and wherein the bottom and shoulder are provided at curved portions thereof with inwardly foldable fold lines.
