Abstract
The present invention provides a pail and cradle system and method for collectively containing one or more chemicals. The cradle comprises an interior surface having an opening with a circumferential rim for reception onto the lip of a pail. The cradle further comprises an extended return so that when the lugs of a lid are crimped onto the pail, the cradle return is clamped by the lugs against the sidewall of the pail. A gasket is mounted under the rim of the cradle so that a seal is formed between the cradle and the top lip of the pail. The lid for the pail further comprises a groove in which a gasket is mounted for sealing the lid against the rim of the cradle when the lid is crimped to the pail assembly.
Claims21
A container for storing and transporting one or more chemicals, comprising:
- a pail having a bottom joined with one or more sidewalls forming an opening with the upper end of the sidewalls forming a rim;
- a cradle having an interior surface forming a storage receptacle and an opening with a circumferential rim forming a groove aligned for mating with said rim of said pail, wherein said cradle further comprising an elongated return outwardly extending down from said rim;
- a gasket mounted within the cradle groove;
- a lid comprising a circumferential groove with a gasket positioned within said groove and aligned for reception over the rim of the cradle and the pail rim, and one or more lugs crimped to the cradle over the pail rim.
A method of collectively packaging a first chemical and second chemical separately into a secure container system, said method comprising the steps of:
- placing the first chemical into the bottom portion of a pail;
- inserting a gasket under a rim formed at the top of a cradle;
- inserting the rim of the cradle onto the rim of said pail, wherein said cradle has an extended return that outwardly extends from said cradle rim;
- placing the second chemical in a recess of said cradle;
- mounting a groove of a lid having a gasket mounted therein over the rim of a cradle;
- and
- securing the extended return of the cradle by crimping lugs of said lid to the sidewall of the pail.
A container system for storing and transporting one or more chemicals, comprising:
- a pail having a bottom joined with one or more sidewalls forming an opening bounded by a circumferential rim;
- a cradle having an opening defined by a circumferential rim forming a groove aligned for mating with said rim of said pail;
- a lid for said pail comprising a circumferential groove aligned for reception onto the rim of the cradle and the rim of the pail;
- said lid further comprising one or more lugs secured to the cradle and to the pail,
- wherein said cradle further comprises a return extending outwardly from said cradle rim, with said return having a length sufficient to be clamped by said lugs against the sidewall when said lid lugs are crimped onto the assembly.
