[object] To provide a seamless can body in which the sheet thickness of a raw sheet (blank) is reduced, pressure resistance of a can bottom is enhanced, buckling is restrained, and problems with blacking and cleaning are solved, and a manufacturing method of the seamless can body. [Solving Means] A seamless can body 1 having a tubular body section 10 and a can bottom section 20. The can bottom section 20 includes an outer circumferential bottom section 202a extending from a lower end of the tubular body section 10 such as to decrease in diameter toward the inside and an annular grounding section 202E positioned further inside than the outer circumferential bottom section 202a. In a case where t1 is the sheet thickness of the outer circumferential bottom section 202a and where t2 is the sheet thickness of the annular grounding section 202b, the relation of t2>t1 is satisfied.

A plastic preform includes a hollow body portion including a closed base portion and a lower portion and a lower portion extending upwardly from the closed bottom portion; and a neck portion extending upwardly from the lower portion. The neck portion includes a dispensing opening positioned at a top of the neck portion, threads positioned below the dispensing opening, a tamper-evident formation having a lower surface and positioned directly below the threads, and a support flange having an upper surface and a lower surface and positioned below the tamper-evident formation. In an embodiment, the plastic preform is formed of a material comprising polyethylene terephthalate (PET), and a vertical distance from the lower surface of the tamper-evident formation to the lower surface of the support flange is from 0.125 to 0.150 inches. Containers and methods for molding preforms and making containers are also disclosed.

A flexible container includes a tray made of silica gel. The tray is integrally formed with at least one placement cavity with an opening at its top portion. A peripheral flange extends outward from a peripheral edge of the tray. The peripheral flange continuously surrounds the peripheral edge of the tray, and the peripheral flange is embedded with a reinforcing ring. A cross-section of the reinforcing ring has a longitudinal length greater than a lateral length. The invention adopts the reinforcing ring with its cross-section having the longitudinal length greater than the lateral length as a frame reinforcing element, and the reinforcing ring is embedded in the peripheral flange extending outwardly from the edge of the tray.

A container has a container body extending along a longitudinal axis from a bottom end to a top end. The container body may define an internal cavity for holding a substance. The container body may include one or more shoulders, such as a first and/or second shoulder (e.g., axial shoulder). The shoulders may be located at the top end of the container. The container may include a neck located (e.g., nesting) between the first and second axial shoulder. The neck may be configured to accept a closure device. The neck may have an inner surface that defines a passageway into the internal cavity. The container may include one or more impact absorbing regions, such as a first axial impact absorbing region. The first axial impact absorbing region may be configured to absorb an axial force applied to the first axial shoulder and/or the second axial shoulder.

Provided is a can body in which a skirt part of the cap attached to a curl part certainly wraps to fixable and pressure resistance can be improved. A cylindrical part and a mouth part connected with a neck part with a smaller diameter than the cylindrical part are provided with; the mouth part has a curl part at an outer peripheral part which is made by folding a tip outward in a radial direction to round up; and in a vertical cross section on a can axis, a concave part is formed toward a lower side in the can axis direction, between an outer peripheral-lower side bent part which is convex diagonally downward on an outer peripheral part of the curl part and a curl end part having the tip.

A water resistant tote box is provided. The tote box includes a base, longitudinally extending sidewalls, laterally extending end walls, and a two-piece lid. The base includes a concave lower surface that matches a convex upper surface of the lid, for preserving the structural integrity of the convex upper surface when stacking a like tote box thereon. The two-piece lid includes a pair of lid halves including a rear end hingedly attached to the sidewalls and a free end including interlocking flaps that are securable via a line of connection. Drain troughs disposed on the walls are in fluid communication with drain channels disposed on the lid, enabling moisture to flow off the top of the tote box. Drain gutters disposed on the lid halves are configured to direct moisture, permeating the line of connection, towards the walls. In this way, the tote box has a synergistic effect of resisting water by directing moisture away from the top of the tote box and preventing moisture from leaking into its interior.
