Abstract
Systems and containers for holding and transporting potentially hazardous materials are disclosed. Assembled containers may have locking mechanisms reducing the possibility of the containers being opened by persons that are not opening the container in a safe environment. Moreover, containers with releasably securable members for carrying substances such as frozen carbon dioxide, used for maintaining cold temperatures of various items are disclosed.
Claims5
A system for holding frozen carbon dioxide, comprising:
- a first container member defining a cavity and having:
- a top including:
- a generally planar surface configured to display a first warning;
- a vent;
- and
- a clip extending over the vent;
- a first side including:
- a first plurality of locking members;
- a first plurality of ridges;
- and
- a plurality of protrusions, extending in a direction generally away from the top;
- a second side including:
- a second plurality of locking members;
- a second plurality of ridges;
- and
- a plurality of protrusions, extending in a direction generally away from the top;
- a first end;
- and
- a second end;
- and
- a second container member defining a cavity and having:
- a bottom including:
- a generally planar surface configured to display a second warning;
- a vent;
- and
- a clip extending over the vent;
- a first side including:
- a third locking member;
- a third plurality of ridges;
- a plurality of protrusions, extending in a direction generally away from the bottom;
- and
- a plurality of recesses, extending in a direction generally toward the bottom;
- a second side including:
- a fourth locking member;
- a fourth plurality of ridges;
- a plurality of protrusions, extending in a direction generally away from the bottom;
- and
- a plurality of recesses, extending in a direction generally toward the bottom;
- a first end;
- and
- a second end,
- a cooler including:
- a first compartment;
- and
- a second compartment having at least one tab configured to engage at least one of the clip of the top of the first container member and the clip of the bottom of the second container member:
- wherein the first locking member and the third locking member are configured to mate with each other, and wherein the second locking member and the fourth locking member are configured to mate with each other, securing the first container member to the second container member;
- wherein upon securement of the first container member to the second container member, such that when secured, the system is configured to encase carbon dioxide that is at a solid state and the vents are configured to allow escape of carbon dioxide that is converted from the solid state to a gaseous state, and wherein at least one of the clips is configured to attach the container to an apparatus;
- and
- wherein at least one of the top of the first container member and the bottom of the second container member includes a plurality of vents, at least one of the top of the first container member and the bottom of the second container member includes a plurality of clips, and at least one clip extends over at least a portion of at least one vent.
46 more elements
A container for holding frozen carbon dioxide, the container comprising:
- a first container member defining a cavity and having:
- a top including:
- a vent;
- and
- a clip extending over the vent and further configured to attach the container to an apparatus;
- a second container member defining a cavity and having:
- a bottom including:
- a vent;
- and
- a clip extending over the vent and further configured to attach the container to an apparatus;
- wherein the bottom of the second container member is configured to engage with the top of the first container member, such that when engaged, the container is configured to encase the carbon dioxide in a solid state and wherein the vents are configured to allow escape of the carbon dioxide in a gaseous state;
- and
- wherein at least one of the top of the first container member and the bottom of the second container member further includes a projection, the projection configured to attach to a corresponding member of a cooler, wherein the projection extends over at least a portion of the vent.
