Abstract
A multiple cavity bottle is provided with a joining inner wall providing two sealed cavities for containing differing commodities. Shaping of the inner wall allows viewing of both commodities. Forming the bottle from two substantially symmetrical elements contacting at the inner wall allows use of a common mold for both bottle elements.
Claims34
A multiple cavity bottle comprising:
- a first element with a first cavity having a mating surface and an outer surface;
- a second element with a second cavity having a mating surface and an outer surface, the second element geometrically identical and symmetrical to the first element, the mating surface of the second element complimentary in shape to the mating surface of the first element and the second element engaging the first element with contact of the mating surface of the first element and the mating surface of the second element;
- and,
- means for interconnecting the first element and second element.

A multiple cavity bottle comprising:
- a first element with a first cavity having a mating surface and an outer surface;
- a second element with a second cavity having a mating surface and an outer surface, the mating surface of the second element complimentary in shape to the mating surface of the first element and the second element engaging the first element with contact of the mating surface of the first element and the mating surface of the second element;
- a protrusion extending from a top portion of each of the first element and second element and having an opening in communication with the cavity therein, each protrusion is located on an axis of symmetry and substantially half cylindrical with a flat surface, the flat surface of the protrusion on the first element engaging the flat surface of the protrusion on the second element;
- and,
- means for interlocking the protrusions.

A multiple cavity bottle comprising:
- a first portion with a first cavity having an outer surface;
- a second portion with a second cavity having an outer surface, the first and second portions connected by a mating septum.
A method for manufacturing a multiple cavity bottle comprising the steps of:
- providing a preform having a first portion with a first cavity having an outer surface and a second portion with a second cavity having an outer surface, the first and second portions connected by a mating septum;
- expanding the preform into a stretch blow mold.
A method for manufacturing a multiple cavity bottle comprising the steps of:
- injection molding a preform having two substantially half cylindrical cavities separated by a septum;
- expanding the preform into a stretch blow mold having a fixed portion engaging a neck of the preform and a rotatable portion receiving a base of the expanded bottle;
- and,
- rotating the rotatable portion of the mold to helically shape the mating septum.

A method for manufacturing a multiple cavity bottle comprising the steps of:
- providing a mold with at least one substantially helical inner surface;
- providing a preform with one flat surface;
- engaging the preform in the mold with the flat surface aligned with an initiation of the helical inner surface;
- reheating an expandable portion of the preform;
- inserting a helically shaped stretch rod into the preform with partial pressurization to spirally stretch the preform;
- fully pressurizing the preform into the mold to create a bottle element;
- assembling the bottle element with a second bottle element to create a dual cavity bottle.
