Definitions
- This invention relates to an improved method for rational and low cost manufacture of metal boxes comprising two container bodies separated from each other from metal sheet and preferably tinned strip or the like. Metal boxes as obtained by said method are also within the scope of the invention.
- cylindrical or polygonal boxes with separate lid comprise two substantially glass or cup shaped containers, of which one is generally of a larger depth than the other and makes up the actual container; the other of which is instead the closure lid which is slightly forcibly coupled by partly inseting the inlet thereof on the outer upper edge of the container.
- the most wide spread technique at present used for manufacture of metal boxes of tinned strip or the like, comprising separate bodies interconnected at opposing position comprises the use of plane sheets of tinned strip, as suitably pretreated and/ or in case provided with figures, words and various marks, providing the hollow glass or cup body making up to actual container by a drawing operation, providing a second box-like body forming the lid, of a different height and in some cases of a larger diameter than that of the former body by a second drawing operation of a sheet of a different size than that of the former, and forming in the actual container body an outer annular edge or rim by a further deformation process to make up a peripheral stop for the edge of the lid when at-closed position.
- the manufacture method according to the invention uses the known technique of drawing metal sheets, preferably tinned strip or the like, as previously surface treated (anodizing, painting, ecc.) and provided with figures, ornaments, words and the like, as required.
- cylindrical container bodies 1 all of a same size and having an upper peripheral edge or rim 2 which is slightly outward arcuate and with a bottom 1b of planar or recessed configuration as desired.
- two container bodies are used as those shown in Fig. 1, of which the lower body 1 (fig. 4) is the actual container, and on the other hand the overturned upper body 1a is the removable lid.
- a core as a container body 3 (fig. 2) of thermoformed plastic material, having such an outer diameter than it can be slightly forcibly inserted and in case by interposition of adhesive in the metal body 1.
- the height of said plastic body 3 is larger than that of body 1, so that the projecting cylindrical section 3a of the plastic body can be used as connection means with said lid la. Therefore, the provision of the cylindrical core internally of said bodies 1 and 1a allow the projecting peripheral edges or rims 2 and 2a of said two opposing bodies to come in contact with each other maintaining the metal bodies axially aligned to each other and thus assuring a good sealing for the box.
- the plastic core or body 3 may have its bottom 4 (fig. 2) provided with recesses 5 of spherical cap or spider or other shape to form steady separating and retaining means for some products of specific shape.
- the bottom 4 could also be omitted and the plastic body 3 may thus take the shape of a perfect cylinder, the height of which, if required, could also be such to enable the cylinder to reach the inner bottom of the metal body 1.
