Abstract
A modular system for blow molding a container that include interchangeable components to allow blow molding of different sized and shaped containers using the same blow mold carrier. The system includes an interlocking coupling between the mold halves and retainer plates that allows for more efficient assembly and disassembly. The system can also accommodate molds for making containers have a width greater than 125 mm. Additionally, the system can accommodate a variety of container sizes, from a low as 100 mL up to 3 L.
Claims21
A modular system for blow molding a container, the system comprising:
- a blow mold carrier comprising a first portion, a second portion, and a base portion, wherein the first portion comprises a mold contacting surface extending along a height of the first portion;
- a first mold removably coupled to the first portion, wherein the first mold comprises:
- a flange;
- and
- positioning dentils spaced apart along a height of the flange, wherein the positioning dentils extend out from the flange and are configured to contact the mold contacting surface;
- and
- a second mold removably coupled to the second portion;
- a base mold in the base portion, wherein the first mold, second mold, and base mold together define a blow mold cavity when the first portion, the second portion, and the base portion are coupled;
- a retainer plate having a longitudinal dimension parallel to the height of the flange, the retainer plate comprising protrusions extending perpendicular to the longitudinal dimension, wherein the protrusions are configured to extend into the space between the positioning dentils such that the protrusions contact the mold contacting surface.
An interchangeable mold for blow molding a container, the mold comprising:
- a first mold configured to engage with a first portion of a blow mold carrier, the first mold comprising:
- a pair of flanges extending in opposite directions;
- positioning dentils extending out from the flanges, wherein the positioning dentils are configured to contact a mold contacting surface of the first portion of the blow mold carrier;
- a second mold configured to engage with a second portion of the blow mold carrier;
- a base mold configured to engage with the first portion and the second portion of the blow mold carrier to form a blow mold cavity defined by the first mold, the second mold, and the base mold;
- and
- a retainer plate configured to couple the first mold to the first portion of the blow mold carrier.
