The present invention is to provide a container capable of stably supporting an internal structure unit while effectively suppressing the occurrence of damage, and a method for manufacturing the container.

The container includes: a container main unit that includes a cylindrical base portion, dome portions that have a dome-like shape and are provided at both ends of the base portion, and a tubular first ferrule portion and a tubular second ferrule portion that have communicating holes formed at top portions of the respective dome portions to connect the inside and the outside, and are formed along the axis of the base portion; and an internal structure unit that is housed in the container main unit. The internal structure unit includes a free shaft portion provided on one end side along the axis of the base portion, and a fixed shaft portion provided on the other end side along the axis of the base portion. The free shaft portion is supported on the side of the first ferrule portion so as to be movable along the axis of the base portion. The fixed shaft portion is secured and supported in the communicating hole in the second ferrule portion via an engaging portion formed on the surface of the fixed shaft portion. At least part of the inner peripheral surface of the communicating hole in the second ferrule portion includes a plastically deformable portion to be engaged with the engaging portion.

Methods and apparatus for forming a metallic dome are provided. More specifically, the present invention relates to a metallic dome that may be used to seal an aerosol container. The metallic dome includes a novel flattened relief panel and an inwardly oriented arch configured to deform in response to pressure within the aerosol container exceeding a predetermined amount. In one embodiment, the flattened relief panel is substantially planar. Optionally, the metallic dome includes at least a first inwardly oriented arch with a first radius of curvature and a second inwardly oriented arch with a second radius of curvature.

In some embodiments of present disclosure, a method includes: obtaining an aluminum sheet comprising a 3xxx or a 5xxx alloy having a tensile yield strength as measured in the longitudinal direction of 27-33 ksi and an ultimate tensile strength; wherein the ultimate tensile strength minus the tensile yield strength is less than 3.30 ksi (UTS?TYS<3.30 ksi); and forming a container having a dome from the aluminum sheet.

The present invention relates to a method of manufacturing a metal vessel by way of stamping of vertical halves from a metal sheet, and in particular to a method comprising: stamping at least a first vessel half and a second vessel half from a metal sheet; adhering at least the first vessel half with the second vessel half forming a vessel, the vessel being a single piece article having an opening on one end for ingress and egress of a liquid or a gas and having a seam along two of the vessel vertical walls and along the bottom of the vessel where the first vessel half and the second vessel half make contact; and applying a top finish at the opening of the vessel allowing for a closure to be used to seal and selectively reseal the vessel.

A method for producing a heat transfer tube for a steam generator comprises a step of providing a tube and then applying cold drawing to the tube by using a high-pressure lubricating oil of 40 MPa or more in pressure. After the step of applying cold drawing to the tube, a step of applying a solid solution heat treatment to the tube is conducted. After the step of applying a solid solution heat treatment to the tube, a step of straightening the tube by using a roll straightening machine is conducted. An offset amount of 5 mm or less is formed for at least successive three pairs of upper and lower straightening rolls of the roll straightening machine.

A bottle can made of aluminum alloy has a base portion; a cylindrical body portion connected to an upper end of the base portion; a reduced diameter portion where a diameter reduces from an upper end of the cylindrical body portion to an upper side; a neck portion provided at an upper side of the reduced diameter portion; and a mouth portion having a male thread portion and a bulge portion provided at an upper side of the neck portion. The reduced diameter portion has: a convex curved portion continuing to the upper end of the cylindrical body portion; a concave curved portion continuing to an upper end of the convex curved portion; a lower convex portion continuing to an upper end of the concave curved portion; and an upper concave portion continuing an upper end of the lower convex portion and a lower end of the neck portion.

The present invention relates to a method for interference-joining concentric cylinders, where the smaller cylinder (102) does not fit into the larger cylinder (101), involving the use of auxiliary cylinders inside an assembly chamber (301), such that the interference is momentarily eliminated by means of isostatic pressure, and one cylinder is fitted into the other, yielding an interference-joined thicker cylinder. The pressure is released, and it is removed from the assembly chamber (301) finally leaving only the two interference-joined cylinders. It is possible to assemble 3 or 10 and more cylinders in the same way, assembling a thick cylinder, pre-compressed on the inside and pre-stressed on the outside. Several interference-joined cylinders exert the same stress when the cylinder withstands the maximum pressure, such that it withstands a greater pressure than a single cylinder with the same total wall thickness, which always reduces the stress from a maximum at the inside of the wall to a lower percentage at the outer edge.
