Claims
- 1. A synthetic resin container comprising:
- (A) an integral, thin-walled, biaxially oriented bottle having a longitudinal axis and comprising a top portion, a cylindrical body portion and a semi-spherical bottom portion;
- said top portion comprising a shoulder portion sloping from said cylindrical body portion toward said longitudinal axis, a first cylindrical neck portion extending along said longitudinal axis from said shoulder portion and comprising a radially outwardly extending flange, and a second cylindrical neck portion extending along said longitudinal axis from said first neck portion and comprising annular threads for securing a cap thereto; and
- (B) an upper fitting member disposed symmetrically about said longitudinal axis and comprising a peripheral upper wall portion, a peripheral lower wall portion and a first inwardly extending flange defining a boundary between said peripheral upper wall portion and said peripheral lower wall portion;
- said peripheral upper wall portion extending at least as high as said second cylindrical neck portion and having a part-circular opening therethrough for permitting a vessel to be passed therethrough and disposed adjacent said second cylindrical neck portion;
- said peripheral lower wall portion comprising a lower end fitted to a periphery of said bottle; and
- said first flange sloping towards said longitudinal axis and further comprising means for securing said first flange to said radially outwardly extending flange of said first cylindrical neck portion; and
- (C) a lower fitting member disposed symmetrically about said longitudinal axis and comprising a peripheral wall having top and bottom end portions, and a second inwardly extending flange integral with said bottom end portion;
- said top end portion being in fitting relationship with a periphery of said bottle;
- said bottom end portion comprising a longitudinal cylindrical extension adapted for supporting said container in an upright position and having an outer diameter no larger than an inner diameter of said peripheral upper wall portion of said upper fitting member; and
- said second flange sloping towards said longitudinal axis, and comprising means for securing said second flange to said bottom portion of said bottle.
- 2. A synthetic resin container as claimed in claim 1, wherein said first flange further comprises a C-shape portion at the end thereof for fitting said first flange onto the outwardly extending flange of said first cylindrical neck portion of said bottle.
- 3. A synthetic resin container as claimed in claim 1, wherein a circular projection concentric with said longitudinal axis extends longitudinally downward from said semi-spherical bottom portion of said bottle.
- 4. A synthetic resin container as claimed in claim 3, wherein said means for securing said second flange to said bottom portion of said bottle comprises means for fitting said second flange against said circular projection on said bottom portion of said bottle.
- 5. A synthetic resin container as claimed in claim 4, wherein said means for securing said second flange to said bottom portion of said bottle comprises at least two integral portions of said second flange with said integral portions forming a bent member for snugly fitting against said bottom portion and said circular projection of said bottle.
- 6. A synthetic resin container as claimed in claim 1, wherein said first flange is downwardly sloping.
- 7. A synthetic resin container as claimed in claim 1, wherein said second flange is upwardly sloping and said first flange is downwardly sloping.
