Abstract: A thin-walled metal container is formed with a bottom wall having a substantially flat central panel connected to a curved wall portion through an annular, inclined flat or frustum wall portion. The curved wall portion joins the container side wall and is defined by the base radius. The inclined or frustum connecting wall portion acts as a hinge which enables the central panel to move between an upper, non-tensioned position and a lower, tensioned position. In the upper position, the annular downward facing surface of the curved wall located at the radially outermost periphery of the bottom wall defines a support surface which supports the container against necking, seaming, and filling column loads. After displacement of the central panel to the lower, tensioned position, which may occur after filling as a result of carbonation pressure, the container rests on a series of circumferentially spaced feet. These feet are also radially spaced to permit stacking engagement with the upper seamed end of another container. Since the bottom wall does not rely on inwardly curved mechanical features to resist internal pressurization, a thinner gauge metal can be used to satisfy design parameters and can achieve cost and metal reduction savings.

Abstract translation: 薄壁金属容器形成有底壁，其具有通过环形的倾斜的平坦或截头圆锥壁部分连接到弯曲的壁部分的基本平坦的中心板。 弯曲的壁部分连接在容器侧壁上并由基座半径限定。 倾斜或截头锥形连接壁部分用作铰链，其能够使中心板在上部非拉伸位置和较低张紧位置之间移动。 在上部位置，位于底壁的径向最外周边处的弯曲壁的环形向下的表面限定支撑表面，该支撑表面支撑容器以避免颈缩，接缝和填充柱的负荷。 在将中心板移动到由于碳酸化压力而在填充之后可能发生的下部张紧位置时，容器搁置在一系列周向间隔开的脚上。 这些脚也是径向间隔开的，以允许与另一个容器的上接合端的堆叠接合。 由于底壁不依靠向内弯曲的机械特征来抵抗内部加压，所以可以使用更薄的金属表面来满足设计参数并且可以节省成本和减少金属。

Abstract: A plastic blow molded containr and lid combination wherein the double-walled lid is screwed to the top of the container and a parallel pair of horizontal recesses are provided on opposite sides of the container wall for receiving forks of a forklift for lifting and otherwise manipulating the container with a conventional forklift. The bottom of the container is also provided with forklift access recesses for lifting and manipulating the container from the bottom with a conventional forklift. The underside of the lid is provided with a protrusion for engaging the upper end of a salvage drum within the container to confine the drum between the top and bottom of the container. An override lid lock mechanism is provided to prevent the lid from accidentally unthreading itself. In addition, central portions of the bottom of the container are recessed upwardly with respect to perimeter portions of the container bottom so that the container in an empty condition will stably rest on a surface without easily tipping. The container and lid are blow molded of high density/high molecular weight thermoplastic such as polyethylene.

Abstract: A thickness-reduced deep-draw-formed can obtained by using, as the substrate, a cold-rolled steel plate having a carbon content in the steel of 0.02 to 0.15% by weight, a manganese content in the steel of 0.2 to 1.0% by weight, a mean diameter of crystal grain of smaller than 6.0 .mu.m, a tensile strength over a range of from 35 to 55 kg/mm.sup.2, and a thickness of 0.17 to 0.30 mm in a step of subjecting an organic resin-coated structure of the surface-treated steel plate to the thickness-reducing deep-draw forming. This makes it possible to suppress the generation and accumulation of heat in the organic resin-coated steel plate to a level lower than the conventional levels. Therefore, the organic resin coating is prevented from being peeled off or damaged and, as a result, the corrosion resistance can be markedly improved. Moreover, wrinkles can be effectively prevented from developing at the time of reducing the thickness, and the forming can be continuously carried out at a high speed without being substantially affected by the generation or accumulation of heat. It is further possible to easily carry out the post treatments such as necking, flanging and multi-beading after the forming. The thickness-reduced deep-draw-formed can of the invention is effective particularly for preserving various kinds of juices, coffee, oolong tea and any other beverages after it is hermetically sealed, retort-sterilized and reduced for its internal pressure.

Abstract translation: 使用钢中碳含量为0.02〜0.15重量％，钢中的锰含量为0.2〜1.0％的冷轧钢板作为基材，可以得到厚度减薄的深拉成形物， ，在有机树脂被覆结构体的工序中，平均粒径小于6.0μm，拉伸强度为35〜55kg / mm 2，厚度为0.17〜0.30mm 的表面处理钢板进行厚度减薄深拉成形。 这使得可以将有机树脂涂覆钢板中的热的产生和积聚抑制到低于常规水平的水平。 因此，防止有机树脂涂层被剥离或损坏，结果可以显着提高耐腐蚀性。 此外，在减小厚度的同时可以有效地防止褶皱的发展，并且可以高速连续地进行成形，而不会受到热的产生或积累的显着影响。 还可以容易地进行后处理，例如成型后的颈缩，翻边和多重着色。 本发明的厚度减薄的深拉制罐尤其适用于在气密密封，蒸煮灭菌和内压降低后保存各种果汁，咖啡，乌龙茶和任何其他饮料。

Abstract: A drawn and ironed container body is provided having a plurality of alternating inward and outward segments around the circumference of the stripper bulge and extending through at least a portion of the longitudinal extent of the bulge whereby the minimum column strength of a sampling of such containers is substantially increased. An apparatus for reforming a drawn and ironed container body is also provided, comprising inner and outer members positionable in opposing relation with each other, with at least a portion of the bulge positioned therebetween, the inner and outer members being capable of radial movement relative to each other to form alternating inward and outward segments around the circumference of the bulge and extending through at least a portion of the longitudinal extent thereof. In one embodiment, the inner member is a mandrel for supporting container body and secured to a circular turret and the outer member comprises an arcuate member having a rigid plate and a resilient layer for contacting a portion a container body on the mandrel. As the container simultaneously rotates about its longitudinal axis and revolves around the center axis of the turret, compressive force against the resilient layer forces metal to conform to inward and outward segments in the mandrel.

Abstract: New technology for deep drawing can bodies for use in the manufacture of two-piece cans for food and beverage products from precoated flat-rolled sheet metal can stock in which damage to can stock precoated on both surfaces with an organic coating is avoided and draw-forming of the side wall is controlled to decrease metal requirements. A draw die cavity entrance (47, 74) is selected to provide at least a major portion of its curvilinear surface having a radius of curvature of about five times nominal sheet metal thickness gage, or less, e.g. a maximum radius of curvature of 0.04 inch is used for the more commonly used can stock materials. During cup redraw, nesting of curvilinear clamping surfaces (21, 26) of the prior art is eliminated; the compound curvilinear juncture of a work product cup, between its end wall and side wall, is reshaped about a clamping ring compound curvilinear transition zone (72) of smaller surface area than the cup juncture and, the sheet metal is clamped solely between planar clamping surfaces (63, 71) during redraw to a smaller diameter utilizing a male punch (66) with a punch nose (79) having a significantly larger surface area than that of the cavity entrance zone.

The end portion of the drum shell opposite the carrying and transport ring is set back in conical fashion. To allow handling with standard mechanized drum handling equipment, a wide channel is formed between the vertical contact surface of the ring and the conical section. To this end, the carrying and transport ring is connected to the conical section of the shell by a wide connecting web which forms the bottom of the channel. The web is supported by a support structure. In a first embodiment, the support structure is zig-zag. In a second embodiment, the support structure comprises radially extending projections. Passageways are located in the bottom of the channel to allow runoff of water.
