Abstract: A sample organizer that will retain a number of fluid samples such as blood samples, for example, wherein each such sample is contained in an individual plastic collection tube. The plastic collection tubes fit into horizontally defined apertures which allow the tubes to be inserted without undue force. The apertures are specifically designed to allow secure insertion and retention of blood samples, for example, without promoting hemolysis. The fluted carriage design also prevents the sample collection tubes from spontaneous dislodgment. Sample organizers may be "stacked" or nested due to the lightweight frame design and further, provide for fluid sample identification such as number, name, source, verification, etc.

Abstract: A four-walled, open-topped container having a lid is disclosed in which the lid is insertable into the container for storage along and against one wall of the container. The lid for the container is generally planar and has a trapezoidal shape and the four walls of the container are generally planar, are interconnected, and are joined to a bottom. A rim for engaging the lid is defined by the upper ends of the four walls. The rim is trapezoidal in shape to conform to the lid and has long and short parallel opposed sides and two converging opposed sides. The four walls converge inwardly from the rim to the bottom to a sufficient degree to permit a container to nest within a like container. In addition, the convergence of the walls which define the opposed converging sides of the rim is appropriate to permit the lid to be inserted into the container along and against the wall defining the long parallel side of the rim.

Abstract: A nestable container is disclosed for use with automatic storage/retrieval systems. The container has a bottom wall and diverging side and end walls. The end walls have recessed areas integrally extending into the interior of the container. Engagement members are located completely within the recessed areas such that they do not protrude beyond a plane defined by the major portion of the end walls. An automatic storage/retrieval system engages the engagement member for the purposes of moving the container. The diverging side and end walls and the inboard engagement members make stacking of containers of the same size and dimensions possible. The side walls have recessed areas spaced from the bottom wall and extending into the interior of the container. The side wall recessed areas define a nesting stop to prevent similar containers from nesting too tight when stacked therein.

Abstract: A protective liner for vessels such as cooking pans, which have interior surfaces either natural or covered with thin, nonstick coatings.

The liner is made of a thin flexible material. Its edge section grasps the rim of the vessel to be protected, while its bottom web section and spacer web section substantially cover the interior surfaces of the vessel.

Abstract: A cooking pan assembly is provided which has particular utility in the industrial cooking of food, such as tuna fish. The cooking pan is particularly constructed so that it may conveniently be transported on usual conveyors within the cooking facility. Crimped wire-formed ends are provided for the pan which serve as handles and which prevent the contents of the pan from sliding through the front or rear ends thereof. The wire-formed ends are crimped loosely to the side walls and bottom of the pan for sanitary reasons so that there is only a point contact between the wire-formed ends and the sides and bottoms, and no areas are formed which would be conducive to build up of bacteria. There are no welds between the end members and the bottom or side walls of the pan, since such welds would produce two separate surfaces in intimate contact with one another which could harbor bacteria. The pan assembly is easy to clean thoroughly by a simple spray wash since there are no nooks or crannies in the assembly.
