Definitions

  • the present invention refers to an improvement applied to a can formed in metallic sheet and comprising a tubular body portion, generally presenting a circular section and carrying a bottom wall, an upper neck portion with a contour smaller than that of the body portion, and a transition portion joining the body portion and neck portion and having an end edge which defines the contour of an upper opening for the can, on which is fitted a removable lid.
  • tubular cans obtained in metallic sheet and comprising a body portion, of circular or polygonal cross-section and carrying a bottom wall and an annular upper wall which are peripherally attached, generally by double-seaming, to the lower end edge and upper end edge of the can.
  • This type of construction which is well known in the art, allows the bottom wall and the annular upper wall to exert a function of structuring the body portion of the can, without requiring the incorporation of additional stiffening structural elements.
  • This type of can has the body portion presenting a cross-section which is constant or progressively reduced from the bottom wall to the annular upper wall, the thickness of the metallic sheet being dimensioned as a function of this structural configuration of the can.
  • cans which present a body portion of tubular section inferiorly carrying the bottom wall and which is superiorly joined, through a transition portion, to a neck portion of smaller contour, in whose free upper end edge is double-seamed the peripheral edge of an annular upper wall.
  • the provision of the annular upper wall is fundamental for obtaining the adequate structural resistance of the can, through a metallic sheet of adequate minimum thickness. Without the annular upper wall, the thickness of the metallic sheet of the body portion would have to be considerably increased, with the consequent increase in the cost of the raw material and in the weight of the can.
  • the upper end edge of the can i.e., of the neck portion
  • be bent or otherwise worked to form a curl or outer peripheral projection surrounding the upper opening of the can and defining, jointly with the upper end edge of the latter, a seat for seating a removable lid, comprising a panel portion which incorporates a peripheral tubular portion to be tightly fitted, with interference, in the upper opening, in the interior of the neck portion, said peripheral tubular portion having a free upper edge which is bent, or otherwise worked, to form a curl or outer circumferential rib, to be seated onto the upper end edge of the can, upon the closing of the lid.
  • This prior art construction allows eliminating the annular upper wall and forming an initial tubular body, with a metallic sheet of usual thickness, for example from about 0.21mm to about 0.27mm for 3.6 liter cans, and presenting a cross-section corresponding to that of the neck portion. Subsequently, said tubular body is submitted to an expansion operation, through which are formed the transition portion and the body portion, the latter presenting a concentric cross-section, similar and larger than that of the neck portion. Thus, it is possible to obtain a can with less metallic sheet consumption.
  • a complementary object of the invention is to provide a can as defined above which presents by using a metallic sheet of an adequate minimum thickness for the body portion, the transition portion and the neck portion, a higher resistance against compression axial forces.
  • a further object of the present invention is to provide a can as defined above which, besides presenting a high tightness degree in the lid closure and having higher resistance against compression axial forces, can receive a seal ring that is capable to axially retain the lid closed until the occurrence of an evidenced first opening, as well as to carry a retractable suspension handle.
  • a can of the above-defined type comprising: a body portion carrying a bottom wall; a neck portion, with a reduced section and having an upper edge incorporating an outer peripheral projection defining the contour of an upper opening of the can; a transition portion joining the tubular body portion and the neck portion; and a lid formed by a panel portion incorporating a peripheral tubular portion to be tightly fitted, with interference, in the upper opening of the can, in the interior of the neck portion, and having a free upper edge provided with an outer circumferential rib, to be seated onto the upper end edge of the neck portion.
  • the outer circumferential rib of the lid inferiorly carries an annular gasket, for example a resin washer, to be seated onto the upper end edge of the neck portion upon the lid fitting on the upper opening.
  • annular gasket for example a resin washer
  • the transition portion can externally incorporate, in a single piece with the metallic sheet, a plurality of spaced apart longitudinal ribs joining the transition portion to an adjacent base region of the neck portion.
  • the tubular shaped can 10 comprises: a body portion 11, in whose lower end edge 11a is affixed, generally by double-seaming, the peripheral edge of a bottom wall 12; a neck portion 13 having a concentrical contour, which is similar and reduced in relation to that of the body portion 11, and an upper end edge 13b defining the contour of an upper opening A for the can 10; and a transition portion 14 with a profile inclined in relation to the axis of the can 10 and joining the body portion 11 and the neck portion 13.
  • the upper end edge 13b of the neck portion 13 incorporates an outer peripheral projection 13c.
  • the outer peripheral projection 13c takes the form of a curl of tubular cross-section, obtained by bending the metallic sheet radially outwards in the region of the upper end edge 13b.
  • the cross-section of the curl is circular, but it should be understood that a peripheral projection with different cross-sections, tubular or not, can be formed.
  • the formation of the body portion 11 is initiated by forming a tubular body with a cross-section corresponding to that of the neck portion 13, and which is then radially expanded along part of its height, to define the body portion 11 and the transition portion 14, under methods already known by the prior art, the transition portion 14 remaining inferiorly joined to the body portion 11 by a junction region in convex arc 14a and superiorly joined to the neck portion 13 by a junction region in concave arc 14b.
  • the can 10 further comprises a lid 20 formed in a single piece of stamped metallic sheet, presenting a panel portion 21 occupying great part of the cross-section area of the upper opening A and incorporating a peripheral tubular portion 22 that is configured and dimensioned to be tightly fitted, with interference, in the upper opening A, in the interior of the neck portion 13, this peripheral tubular portion 22 presenting a free upper edge 22b in which is incorporated an outer circumferential rib 22c configured to be seated onto the upper end edge 13b of the neck portion 13.
  • the outer circumferential rib 22c takes the form of a curl of tubular cross-section, obtained by bending radially outwards from the region of the free upper edge 22b of the peripheral tubular portion 22.
  • the drawings illustrate only a curl of circular section, it should be understood that an outer circumferential rib 22 with different cross-sections, tubular or not, can be formed.
  • annular gasket 30 When the lid 20 is fitted in the upper opening A of the neck portion 13, the annular gasket 30 is seated and pressed onto the upper end edge 13b of the neck portion, considerably increasing the tightness degree of the closure of the lid 20.
  • the lid 20 is preferably constructed with its panel portion 21 incorporating a pending skirt 21a which forms, with the peripheral tubular portion 22, a peripheral channel 24, of rectangular section, radially separating the panel portion 21 from the peripheral tubular portion 22, the panel portion 21 lying in a plane higher than that of the bottom wall 24a of the peripheral channel 24.
  • the shaping of the can 10 is made so that the transition portion 14 externally incorporates, in a single piece, a plurality of longitudinal ribs 15, angularly spaced from each other and joining the transition portion 14 to an adjacent lower region 13a of the neck portion 13.
  • the longitudinal ribs 15 can be formed by localized bendings of the metallic sheet that forms the body portion 11, the neck portion 13 and the transition portion 14, upwardly and inclinedly extending, like a bracket, from a median region of the transition portion 14 to the adjacent lower region 13a of the neck portion 13.
  • the longitudinal ribs 15 have their extension limited or only slightly larger than the longitudinal extension of the cross-section of the junction region, in concave arc 14b, which joins the transition portion 14 to the neck portion 13.
  • retaining ring 40 to be adapted to the can 10, which retaining ring 40 is formed in a single piece of plastic material and comprises: an upper annular portion 41, to be seated onto the free upper edge 22b of the peripheral tubular portion 22 of the lid 20; a peripheral skirt portion 42 pending from the upper annular portion 41, laterally tightly surrounding the outer circumferential rib 22c of the lid 20 and the outer peripheral projection 13c of the body portion 11 and incorporating an inner circumferential finger 43 to be seated and axially locked under the outer peripheral projection 13c of the body portion 11, preventing the lid from being removed, without evidencing the necessary use of a lever tool supported in the outer peripheral projection 13c.
  • the retaining ring 40 has its upper annular portion 41 internally incorporating the diametrically opposed ends of a suspension handle 44 which is displaced between a retracted inoperative position, coplanar or considerably coplanar to the upper annular portion 41 and having a median portion 44a connected to the upper annular portion 41 by breakable bridges 44b, and a raised operative position, obtained after the rupture of the breakable bridges 44b.
  • the retaining ring 40 also incorporates, in its upper annular portion 41, a lower tubular projection 46 that is dimensioned to be fitted, with interference, in the interior of the peripheral channel 24 of the lid 20, forcing the peripheral tubular portion 22 of the latter against the neck portion 13, increasing the axial locking between the lid 20 and the neck portion 13 and also the tightness degree in this closure region.
  • the upper annular portion 41 when applied to contain paints, varnishes and similar products, can radially inwardly prolong in relation to the position of the lower tubular projection 46, to form a flap 41a for scraping brushes and broaches when, after the withdrawal of the lid 20, the retaining ring is reconducted to its axially locked position under the outer peripheral projection 13c of the neck portion 13, so that the can 10 can be suspended by the suspension handle 44 and so maintained while its content is progressively removed in a continuous painting operation.
