Definitions

• the present invention refers to a container, for example, a pail or other similar container, constructed in metal sheet and of the type which comprises a tubular body with a circular or polygonal cross-section, formed by a peripheral side wall presenting a lower end edge, to which a bottom wall is affixed, and an upper end edge which surrounds an opening on which is seated and affixed, after the filling of the product to be packaged, an upper wall which can take the form of a lid to be submitted to one or more closing and opening operations.
• a container for example, a pail or other similar container, constructed in metal sheet and of the type which comprises a tubular body with a circular or polygonal cross-section, formed by a peripheral side wall presenting a lower end edge, to which a bottom wall is affixed, and an upper end edge which surrounds an opening on which is seated and affixed, after the filling of the product to be packaged, an upper wall which can take the form of a lid to be submitted to one or more
• the tubular body of the container in the form of a pail presents a certain inverted conicity for allowing the partial telescopic fitting of the tubular bodies, when said bodies are stacked still superiorly opened.
• This constructive arrangement allows a substantial volumetric gain in storage and transport of the tubular bodies of said containers when they are still superiorly opened.
• inverted frusto-conical tubular body has the larger base of the frusto- conical shape situated in a plane axially spaced back in relation to the plane of the upper end edge of the peripheral side wall and in which plane axially spaced back the side wall is deformed to define an outer circumferential projection, which is seated on the upper end edge of the tubular body of a lower container, upon telescopically stacking said tubular bodies.
• these containers has the degree of mutual fitting of their tubular bodies limited by the conicity admissible in the progressive deformation of the metal sheet, which deformation is required throughout the height of the frusto-conical shape.
• each upper tubular body in a telescopic stacking, has only its outer circumferential projection seated on the upper end edge of the lower tubular body.
• the upper tubular body portion which is telescopically fitted in the interior of the lower tubular body, is not axially or radially seated against any "cradle" provided in the interior of the lower tubular body.
• the peripheral side wall of the tubular body of the container presents, axially spaced apart, at least two inverted frusto-conical portions of short height, defining respective circumferential reductions in the contour of the tubular body, which are dimensioned and positioned so that, upon fitting one tubular body inside the other:
• an upper frusto-conical portion of the upper tubular body is seated on the upper end edge of the lower tubular body.
• the peripheral side wall is provided with only two inverted frusto-conical portions
• the lower frusto-conical portion of the upper tubular body is seated on an upper frusto-conical portion of the lower tubular body.
• the peripheral side wall further presents at least one inverted median frusto- conical portion, with short height, axially spaced from the upper and lower frusto-conical portions, defining a respective circumferential reduction in the contour of the tubular body, which median frusto-conical portion is dimensioned and positioned so that, upon fitting one tubular body inside the other:
• the tubular bodies which are generally in the form of pails in metal sheet, can present an easily obtainable shape which can simultaneously provide a fitting of about 3/4 of the height, or even more, of one tubular body inside the other, without submitting the peripheral side wall to a contact which can destroy the finishing of the peripheral side wall of the adjacent tubular bodies, and allowing the expansion of the contour of the tubular body to progressively occur towards the upper end edge of the peripheral side wall, making the reduction of the metal sheet thickness to occur upwardly in parts presenting a constant contour and spaced from each other by the frusto-conical portions which define regions of radial strengthening of the peripheral side wall, as well as seating cradles between the mutually fitted tubular bodies.
• Figure 1 represents a diametrically and longitudinally sectioned partial side view of a container constructed according to the present invention and superiorly closed by a removable lid;
• Figure 2 represents a partial diametrical and longitudinal sectional view of two containers of the type illustrated in figure 1, without their lids and telescopically fitted one inside the other;
• Figure 3 represents an enlarged detailed view of the lower region of the containers illustrated in figure 2;
• Figure 4 represents an enlarged detailed view of the upper regions of the containers illustrated in figure 2.
• the present container is of the type which comprises a tubular body C, formed in metal sheet, usually tinplate, and presenting a peripheral side wall 10 with any circular or polygonal cross-section, but usually circular and having a lower end edge 11, to which a bottom wall 20 is affixed, for example by double-seaming, and an upper end edge 12 surrounding an opening A and which is conformed to receive and retain an upper wall which, in the illustrated example, takes the form of an also metallic lid T to be removably fitted and retained on said opening A.
• the container in metal sheet presents the upper end edge 12 of the peripheral side wall 10 which is outwardly bent so as to define a finishing bead 13.
• the finishing bead 13 is obtained by outwardly, downwardly and inwardly bending the upper end edge 12, so as to present a tubular or semi-tubular cross-section. Nevertheless, the finishing bead 13 may present different cross-sections, provided that it defines an outer peripheral step in the region of the upper end edge 12 of the peripheral side wall 10.
• the lid T may be constructed of different manners, as long as it can be applied and hermetically retained against the upper end edge 12 of the peripheral side wall 10, by the filler, after filling the product in the interior of the container.
• the peripheral side wall 10 presents two or more frusto-conical portions axially spaced apart to define respective circumferential reductions in the contour of the tubular body C.
• the peripheral side wall 10 is provided with a lower frusto-conical portion 14, a median frusto-conical portion 15 and an upper frusto- conical portion 16, which are axially spaced from each other and in relation to the lower end edge 11 and upper end edge 12 of the peripheral side wall 10, by approximately equal distances.
• these distances need not be the same and they can vary as a function of the desired structural strength for the different tubular portions 17 of the peripheral side wall 10, which are defined between the frusto-conical portions 14, 15, 16 and between the lower frusto-conical portion 14 and upper frusto-conical portion 16 and the respective lower end edge 11 and upper end edge 12 of the peripheral side wall 10.
• peripheral side wall 10 can be provided with only one lower frusto-conical portion 14 and one upper frusto-conical portion 16, without the provision of any median frusto-conical portion 15.
• the dimensioning of the frusto-conical portions 14, 15, 16 is made so that the inclined wall portion presents an angle not higher than 45° in relation to the plane which contains the axis of the container, so that the structural strength of the tubular body C in relation to the axial compression is not unacceptably impaired.
• This construction allows the largest expansion of the metal sheet to be progressively and upwardly applied to the different tubular portions 17 of the peripheral side wall 10, allowing the thinner walls to be defined in the upper tubular portions 17 which are subject to a smaller pressure of the product to be filled and which are radially reinforced by the nearest frusto-conical portions.
• the tubular body C can be formed from a metal sheet with a smaller thickness, without the container having its peripheral side wall structure inadequately weakened.
• the tubular portions 17 of the peripheral side wall 10 present a constant circular or polygonal cross-section throughout the height thereof, maintaining a radial spacing or gap in relation to the adjacent wall tubular portions of other tubular body C, in telescopic stacking, corresponding to the radial width R of the frusto-conical portions 14, 15, 16 associated with the different tubular portions 17.
• the lower end edge 11 of the peripheral side wall 10 of the upper tubular body C is seated on the lower frusto-conical portion 14 of the lower tubular body C and the upper frusto-conical portion 16 of the upper tubular body C is seated on the upper end edge 12 of the lower tubular body C, independently of being or not provided one or more median frusto-conical portions 15.
• the lower frusto-conical portion 14 of the upper tubular body C is seated on the median frusto-conical portion 15 of the lower tubular body C and the median frusto-conical portion 15 of the upper tubular body C is seated on the upper frusto-conical portion 16 of the lower tubular body C.
• This constructive arrangement allows the frusto-conical portions 14, 15, 16 of a tubular body C to operate as circumferential steps or “cradles" for the seating of the lower end edge 11 and of the lower frusto-conical portion 14 and median frusto-conical portion 15 of other tubular body C fitted inside the lower one, guaranteeing high stability and high interpenetration fitting, without occurring frictional contact between the tubular portions 17 of the peripheral side wall 10 of each two tubular bodies C fitted one inside the other.
