a pair of top wall extensions extending from the top wall, the top wall extensions each located beside a respective end of the latch such that the latch is located between the top wall extensions;
at least one intermediate support extension extending from the top wall, the at least one intermediate support extension located between the pair of top wall extensions, the intermediate support extension being received in the slot on the latch in both locked and unlocked positions of the latch; and
a pair of interlocking elements on the latch and a cooperating hook element on the second component for engaging the pair of interlocking elements, the pair of interlocking elements being individually spaced towards respective ends of the face component.
8. The carrying case as claimed in claim 7 wherein the liner includes an opening to facilitate purging from the container.
9. The carrying case as claimed in claim 7 wherein both components are made of translucent or at least partially translucent material, and wherein the liner is opaque.
10. A carrying case as claimed in claim 7 wherein one of the components includes an opening to facilitate purging from the container.
11. A carrying case as claimed in claim 7 wherein the liner fitting in the space in the surrounding material is a single liner.
12. The carrying case as claimed in claim 7 wherein the latch is a centrally located single latch.
13. A carrying case comprising:
a generally rectangular body of surrounding material having a first component and a second component for opening and closing together thereby to provide access to a space defined by the surrounding material, each component having a sealing area for location adjacent a respective sealing area of the opposite component and walls for each of the first and second components;
a hinge mounted exteriorly between the first and second components;
a liner fitting in the space in the surrounding material;
a latch mounted exterior to a top wall and a bottom wall, the top and bottom walls each being one of the walls for the first and second components respectively, the latch having two ends and an elongated face component, the elongated face component having an extension to allow a finger of a user to unlock the latch by a lifting action on the extension, the lifting action being an action in an outward direction away from the bottom wall;
a pair of top wall extensions extending from the top wall, the top wall extensions each located beside a respective end of the latch such that the elongated face component of the latch extends longitudinally from one top wall extension to the other top wall extension;
at least one intermediate support extension extending from the top wall, the at least one intermediate support extension having a width and being located between the pair of top wall extensions;
a first length and second length of the latch, the latch being located such that: (a) the first length of the latch is located between one of the top wall extensions and the closest intermediate support extension to the one top wall extension; (b) the second length of the latch is located between the other top wall extension and the closest intermediate support extension to the other top wall extension; the first length and second length both being substantially longer than the width of the at least one intermediate support extension; and
an interlocking element on the latch and a cooperating hook element on the second component for engaging the interlocking element.
14. The carrying case as claimed in claim 13 further including a pair of bottom wall extensions extending from the bottom wall, the bottom wall extensions each located beside a respective end of the latch such that the latch is located between the bottom wall extensions.
