The invention relates to a reaction container and a method for producing the reaction container, and provides a low-cost reaction container which is capable of consistently, quickly, and efficiently performing a process that includes a reaction such as extraction or amplification of a nucleic acid, while saving user's trouble without increasing the scale of the device. The reaction container is configured to comprise: one or two or more housing parts for reactions comprising: a narrow-mouthed piping part in which a reaction reagent or a portion thereof is housed or is housable; a wide-mouthed piping part that is communicated with the narrow-mouthed piping part and provided on an upper side of the narrow-mouthed piping part, and has an aperture that is wider than an aperture of the narrow-mouthed piping part; and a punchable film provided such that it partitions an interval between the wide-mouthed piping part and the narrow-mouthed piping part.

A drawn aluminum can shell has a peripheral crown which is double-seamed with an end portion of an aluminum can body to provide a can end having a generally flat center panel connected by an inclined curved or straight panel wall to an inclined inner wall of an annular U-shaped countersink. The countersink has an outer wall which connects with an inclined lower wall portion of a chuck wall at a junction below the center panel, and the chuck wall has a curved or inclined upper wall portion which connects with an inner wall of the crown. The chuck wall also has an intermediate wall portion forming a break, and the inner bottom width of the countersink is less than the radial width of the panel wall. The inclined upper wall portion of the chuck wall extends at an angle greater than the angle of the inclined lower wall portion of the chuck wall.

A sheet metal planter comprises three panel types, can be assembled with readily available tools, can be disassembled to fit in a compact space, can be made in more than one shape, does not require fasteners in one embodiment or places a modest load on fasteners in another embodiment, and is aesthetically pleasing.

A container and a method of manufacturing a container having a base portion and a sidewall which together form a partially enclosed space for holding a fluid; and a cooling element fixedly connected to the base portion, the cooling element comprising a cavity and a cooling material sealed within the cavity.

A grain storage bin includes a cylindrical wall formed by a plurality of panels arranged in rows with a bottom edge of a first row bolted to a top edge of a second lower row. At each joint the bottom edge of the first upper row is overlapped with and outside of the outer surface of top edge of the second lower row and the bottom edge is fastened to the top edge by bolts carrying spacers as to define a first channel along the joint for passage of air. A cover strip overlies the channel and extends from an upper edge of the strip at the inner surface of the first panel above the channel to a lower edge of the strip which is fastened to the top edge so as to define a second channel so that air can pass between the interior and the exterior through the first and second channels while the particulate material is prevented from escaping through the first channel by the cover strip.

A composite includes a multilayer polyethylene terephthalate (PET) film having a base layer and an adjacent skin layer. The PET of the skin layer has inherent viscosity of about 0.70-0.90 and carboxyl endgroup concentration of less than 25 eq/T. The base layer can be affixed to a thin metal sheet. Optionally, the base layer of a second multilayer PET film with a skin layer inherent viscosity of about 0.70-0.90 and carboxyl endgroup concentration of less than 25 eq/T can be affixed to the opposite side of the metal sheet. The composite is suited for making food and chemical containers such as food storage cans that resist blush discoloration from steam contact during container formation and age degradation during extended storage of harsh chemical products.

The inclined upper wall portion of the chuck wall extends at an angle greater than the angle of the inclined lower wall portion of the chuck wall.

A housing has a bottom part with a bottom and bottom part sidewalls. A top is provided that has a top and top part sidewalls. The top part is provided on one of the top part sidewalls with one or more integrally formed monolithic first tabs that project outwardly from the top part sidewall. The one or more first tabs each have one or more first screw holes. A first profiled section connector is provided with a first profiled part that has one or more first screw-in options aligned with the one or more first screw holes, respectively. The first profiled part is screw-connected through the one or more first screw holes and the one or more first screw-in options to the top part. The first profiled section connector connects the bottom part and the top part to each other.
