Abstract
Abstract A two-part liquid container with a breakable partition which has a first half container (1) sealing a sheet at a neck portion (6) thereof for containing first liquid; an intermediate cylindrical member (3) for connecting a cylindrical sealing piece through a collapsible piece at the lower end thereof to spirally engage the lower half part thereof with the outer periphery of the neck portion of the first half container (1); a a second half container (2) sealing a sheet at the bottom opening thereof and having a cutting blade (12) depending to the vicinity of the bottom therein for engaging the lower part thereof impossible to turn with the upper half part of the intermediate member (3); and a sealing member for sealing the upper opening of the second half container. Thus two liquid can be readily mixed without necessity of particular mixing container nor overflowing the liquid.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
163 words
A two-part liquid container with a breakable partition characterised in that it comprises: (a) a first half container (1) sealed by a sheet (8) at a neck portion (6) thereof for containing a first liquid; (b) an intermediate cylindrical member (3) for connecting a cylindrical sealing piece (22) through a collapsible piece (21) at the lower end thereof, a lower half part of the intermediate cylindrical member (3) spirally engaging the outer periphery of the neck portion (6) of said first half container (1); (c) a second half container (2), for containing a second liquid, sealed by a sheet (10) at a bottom opening thereof and having a cutting member (12) depending to the vicinity of the bottom therein, a lower-part of the second half container (2) engaging an upper half part of the said intermediate member (3) in a manner inhibiting relative rotation therebetween; and (d) a sealing member (24) for sealing the upper opening of the said second half container (2).
Claim 2
Dependent Claim
163 words
A two-part liquid container with a breakable partition characterised in that it comprises: (a) a first half container (1) sealed by a sheet (8) at a neck portion (6) thereof for containing a first liquid; (b) an intermediate cylindrical member (3) for connecting a cylindrical sealing piece (22) through a collapsible piece (21) at the lower end thereof, a lower half part of the intermediate cylindrical member (3) spirally engaging the outer periphery of the neck portion (6) of said first half container (1); (c) a second half container (2), for containing a second liquid, sealed by a sheet (10) at a bottom opening thereof and having a cutting member (12) depending to the vicinity of the bottom therein, a lower-part of the second half container (2) engaging an upper half part of the said intermediate member (3) in a manner inhibiting relative rotation therebetween; and (d) a sealing member (24) for sealing the upper opening of the said second half container (2).
Claim 3
Dependent Claim
