Abstract
A hot-fillable blow molded plastic container having a finish with an opening; a base; a lower bumper transition; an upper bumper transition and a tubular dome. The upper bumper transition and lower bumper transition defines a label mounting region. The label mounting region includes a circumferential ring adjacent to the upper bumper transition a vacuum panel. The tubular dome can be between the upper bumper transition and the finish and can has a cross sectional shape that is substantially the same throughout. The tubular dome includes an upper bell and a lower bell separated by a peripheral waist that has a diameter less than that of the upper and lower bell.
Claims27
A hot-fillable blow molded plastic container comprising:
- a finish with an opening;
- a base distal to said finish;
- a lower bumper transition adjacent to said base;
- an upper bumper transition that, together with said lower bumper transition, defines a label mounting region that comprises a vacuum panel region;
- a tubular dome between said upper bumper transition and said finish having cross sectional shape that is substantially the same throughout and comprising
- an upper bell;
- a peripheral waist;
- and
- a lower bell;
- and
- a circumferential ring below said dome.
A hot-fillable blow molded plastic container comprising:
- a finish with an opening;
- a base distal to said finish;
- a lower bumper transition adjacent to said base;
- an upper bumper transition that, together with said lower bumper transition defines a label mounting region having a width that is less than a width of said base and comprising
- a circumferential ring adjacent to the upper bumper transition;
- and
- a vacuum panel region below said circumferential ring;
- and
- a substantially cylindrical dome between said upper bumper transition and said finish and having a cross sectional shape that is substantially the same throughout and comprising
- an upper bell;
- a peripheral waist;
- and
- a lower bell having a width that is larger than the width of said label mounting region and approximately equal to the with of said base;
- wherein said upper bumper transition is linearly tapered between said lower bell and said label mounting region and said lower bumper transition is linearly tapered from said bumper transition is linearly tapered between said label mounting region and said base;
- and
- said upper bumper transition and said circumferential ring cooperate to provide top load strength and resistance to ovalization.
A method for making a container having a predetermined top load strength and resistance to ovalization comprising,
- providing a container having
- a finish with an opening;
- a base distal to said finish;
- a lower bumper transition adjacent to said base;
- an upper bumper transition that, together with said lower bumper transition defines a label mounting region that comprises a circumferential ring adjacent to the upper bumper transition and a vacuum panel region;
- a tubular dome between said upper bumper transition and said finish having cross sectional shape that is substantially the same throughout and comprising
- an upper bell;
- a peripheral waist;
- and
- a lower bell;
- and
- adjusting a width of at least one of said upper bell, said waist, said lower bell and said label mounting region;
- thereby providing a container having a predetermined top load strength and resistance to ovalization.
