A container having enhanced wall integrity and a rotational element is provided that includes a sidewall having polygonal cross-sectional shape and an alignment structure formed therein. The alignment structure is adapted for orienting the container with respect to a second container such that the panel sections of the containers become parallel with one another and the containers may be fully nested one within the other. The alignment structure can be recessed into the sidewall to form peaks and valleys along an inner surface of the container. The peaks include first and second faces sloping in opposite directions designed to direct corners of the first container's sidewall toward the interior valleys of the second container in order to orient the containers as they are stacked.

A container includes a pulp-formed shell configured to contain materials therein, the pulp-formed shell comprising an opening through which materials may pass. A collar is connected to the pulp-formed shell and has one or more features configured to engage at least a portion of the pulp-formed shell. A component is rotatably coupled to the collar. Rotation of the component is operable to move the materials within the pulp-formed shell along an axis of the pulp-formed shell.

The alignment structure can be recessed into the sidewall to form peaks and valleys along an inner surface of the container. Alternatively, the alignment structure can protrude from the sidewall to form peaks and valleys along an inner surface of the container. The peaks include first and second faces sloping in opposite directions designed to direct corners of the first container's sidewall toward the valleys of the second container in order to orient the containers as they are stacked.

The present invention provides for a single-use, disposable container and methods and apparatuses for testing liquid samples in a non-destructive fashion using the single-use, disposable container within a liquid sample analyzer. The single-use, disposable container reduces the overall sample volume contact within a flow path of the liquid sample analyzer, decreases the cleaning solution and drying time needed between sample analyses, and minimizes formation of particles during use of the container.

The present invention relates in general to the improved containment of biological fluids. In particular, a method and apparatus for collection and preservation of fluid samples in accordance with the present invention results in collection of semen having improved viability both at the time of collection and after storage. The disclosed methods and apparatuses methods support a wide variety of applications for containment of biological fluids related to human and veterinary medicine including, but not limited to, human reproductive medicine and animal husbandry.

[Problem] To provide a polyester resin-coated metal sheet which has excellent coating material adhesion capable of withstanding severe forming processing while retaining high decorative property and photoluminescence property and a container using the same. [Solution] The polyester resin-coated metal sheet of the present invention includes a metal sheet, and a non-oriented polyester resin formed of a plurality of layers provided on at least one surface of the metal sheet. A surface layer and an adjacent layer in contact with the surface layer, of the plurality of layers, have a difference therebetween in melting temperature of not less than 10° C., and a difference in tensile stress at an elongation of 250% under an environmental temperature of 70° C. of less than 3 MPa in tensile tests in a single-layer film state corresponding to each layer, and the surface layer contains fine particles.
