Multiple seal storage and transport container
First Claim
1. A container suitable for storing and transporting electrical storage batteries containing corrosive liquid, comprising:
- a container body and a lid connected thereto by a hinge;
one of said body and said lid including a first mating surface, and the other of said body and said lid including a second mating surface, said first and second mating surfaces mating with each other when said lid is closed onto said body to form a seal therebetween, wherein;
said first mating surface includes a major ridge and two minor recesses disposed on either side of said major ridge;
said second mating surface includes a major recess and two minor ridges disposed on either side of said major recess;
said major ridge being larger than both of said minor ridges; and
whereby when said lid is being closed said major ridge first partially engages said major recess and guides said minor ridges into partial engagement with said minor recesses if the lid is skewed, with the major ridge engaging the major recess and the minor ridges engaging the minor recesses when said lid is fully closed onto said body.

Abstract
A container suitable for storing and transporting hazardous materials such as alkali wet cell batteries in an aviation environment includes a container body and a hinged lid made of cross linked polyethylene, latches, and a triple tongue-in-groove seal around the rim of the container opening. The triple tongue-in-groove seal includes two smaller tongue-in-groove seals with a larger tongue-in-groove seal disposed therebetween. The larger tongue-in-groove structure provides structural strength to help prevent the lid from skewing when the container suffers stress such as an impact at a corner, and also helps to guide the lid and base into proper alignment when the lid is being closed. The smaller tongue-in-groove seals provide double redundant sealing to help contain hazardous materials inside the container without making the rim of the container excessively wide.

5. A storage container suitable for containing hazardous materials comprising:
-
a container body; and
a lid connected to said body by a hinge, said body and said lid each having four sides;
wherein a rim on one of said body and said lid defines a first rim, and a rim on the other of said body and said lid defines a second rim;
said first rim includes;
first and second grooves for receiving corresponding first and second ridges on said second rim;
first and second sealing gaskets disposed in said first and second grooves, respectively; and
an angled portion between said grooves, said angled portion being capable of at least partially engaging a corresponding guiding surface on said second rim when said lid is misaligned with said base and is partially closed but before said ridges engage said grooves, said angled portion and said guiding surface cooperating together to guide said lid and said body together as said lid is closed so that said ridges properly align with said grooves and mate therewith when the lid is fully closed. - View Dependent Claims (6, 7, 8, 9, 10, 11)

12. A container comprising:
-
a box and a lid;
a hinge connecting said lid to said box; and
two tongue-in-groove joints formed at the interface between said lid and said box, said tongue-in-groove joints including first and second tongues and respective first and second grooves, the tongues fitting into the respective grooves when the lid is closed down onto the box;
wherein the first tongue is at least 50% taller than the second tongue. - View Dependent Claims (13, 14)

15. A container comprising:
-
first and second box portions hinged together to define a box when closed together;
said first box portion having a first rim and said second box portion having a second rim, said rims abutting each other when said container is closed; and
wherein;
said rims together include at least first and second ridges and corresponding first and second grooves for receiving said ridges;
the two ridges are generally oppositely oriented; and
said first ridge is larger than the second ridge. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
