Patent number: 8864735Abstract: 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.Type: GrantFiled: September 25, 2007Date of Patent: October 21, 2014Assignee: Nipro CorporationInventors: Yoshihiko Sano, Hitoshi Futagawa, Toshihiro Kikuchi

Patent number: 5706937Abstract: A flexible and dual-chambered container includes a first frontal sheet fusion bonded to a first rear sheet to define a first chamber for containing, for example, a medical liquid. The first frontal sheet is a flexible and transparent sheet for intercepting water, moisture, and oxygen gas. The first rear sheet is a flexible composite sheet composed of aluminum foil and a water-absorbing stratum. A second frontal sheet is fusion bonded to a second rear sheet to define a second chamber for containing, for example, a medical liquid. The second frontal and rear sheets are joined to the first frontal and rear sheets so that the first and second chambers are isolated by a breakable or weak seal. An opaque and flexible cover sheet composed of aluminum foil is removably disposed on the first frontal sheet. When the weak seal is broken by manually compressing the second chamber, the first and second chambers are brought into liquid communication.Type: GrantFiled: March 18, 1996Date of Patent: January 13, 1998Assignee: Nissho CorporationInventors: Hitoshi Futagawa, Noriyoshi Yamamoto, Masanobu Iwasa
