Definitions

• the present invention refers to a closure arrangement to be applied to a can obtained in metallic sheet and of the type which comprises a tubular body presenting a peripheral side wall with a circular or polygonal contour and having a lower end portion, affixing or incorporating a bottom wall, and an upper end portion carrying, internally, a structural ring defining an opening to access the interior of the can, and a seat on which is seated and retained a sealing element, in the form of a removable and reclosable lid which is stamped in metallic sheet or molded in plastic material, or in the form of a generally metallic film which is peripherally glued on the structural ring and definitively removed upon the first opening of the can.
• Prior art cans with a press-fit lid are well known, in which the lid is press-fitted in a structural ring which is externally double-seamed to an upper edge of the peripheral side wall of the tubular body of the can.
• the tightness is guaranteed when the lid is fitted in the seat defined in the structural ring.
• the press-fit lid is constructed in plastic material and comprises a sealing portion which is removably seated and retained in the seat defined in the structural ring, and a manually breakable seal provided around the upper end portion of the tubular body of the can.
• Another known solution comprises the provision of a structural ring, whose upper face defines an annular surface for the seating and gluing of the marginal portion of a seal, usually in aluminum foil and which is manually detached upon the first opening of the can.
• a plastic overlid or cover that is removably fitted over the upper edge of the peripheral side wall of the tubular body, in order to protect the content of the can after the seal has been removed.
• a piece for defining the structural ring which, independently of the different shapes it may present, it has to be externally double seamed to the upper edge of the peripheral side wall of the tubular body of the can.
• the provision of the structural ring is mandatory to impart the necessary structural strength to the open upper end portion of the tubular body of the can and also to define the seat for the seating of the sealing element in the form of a metallic lid, plastic lid or seal.
• the structural ring is defined as a separate piece in relation to the tubular body, consuming a respective quantity of tin plate for the formation thereof and requiring to be double seamed so as to be tightly affixed to the upper edge of the peripheral side wall of the can.
• the operation of double seaming the known structural ring considerably limits the possibilities of reducing the manufacture costs of the cans.
• the present closure arrangement is applied to a can of the type presenting a tubular body, of circular or polygonal cross section,, which is inferiorly closed and comprises: a peripheral side wall provided with an upper edge; and a structural ring internal to the tubular body and which is hermetically united to the peripheral side wall so as to define an upper opening of the can and a seat for the seating of a sealing element .
• the structural ring is defined by a circumferential rib formed by a recess in the peripheral side wall which is axially spaced back in relation to the upper end of the latter and projecting radially into the tubular body.
• the construction proposed by the present invention allows the structural ring of the can to be defined by deformation of the peripheral side wall of said can, saving not only the material that would be used for stamping the double seamed structural ring of the prior art, but also the double seaming operation of said ring to the structure of the tubular body of the can.
• the circumferential rib that defines the new structural ring can be constructed so as to define a seat for the seating of a sealing element which can take the form of a press-fit lid stamped in metallic sheet or molded in plastic material or a tamper evident seal, which is peripherally and removably glued over the annular upper face of said circumferential rib.

• Figure 8 is a partial diametrical sectional view of a can tubular body constructed according to another embodiment.
• the closure arrangement of the present invention is applied to a can generally made of tin plate and presenting a tubular body 10 with a circular or polygonal cross- section and which is inferiorly closed by a bottom wall (not illustrated) and comprising: a peripheral side wall 11 provided with an upper edge 12, and a structural ring 13, internal to the tubular body 10 and which is hermetically joined to the peripheral side wall 11, in order to define an upper opening 14 for the can, as well as a seat 15 onto which will be seated a sealing element 20, which can present different constructions, as described ahead.
• Figures 1-4 of the appended drawings are related to a closure arrangement in which the sealing element 20 is defined by a film 21, generally in impermeable material and preferably metalized, which is removably glued to the upper face 16a of a circumferential rib 16.
• This sealing element 20 is constructed in such a way as to be definitively removed by the user from its mounted position upon the first opening of the can so as to give access to the interior of the can.
• the circumferential rib In this type of construction, the circumferential rib
• the circumferential rib 16 presents its upper face 16a usually flat and orthogonal to the axis of the can to facilitate the hermetic and secure gluing of the marginal portion of the film 21 on the circumferential rib 16.
• the circumferential rib 16 presents a cross section in the approximate shape of a horizontal "U", with the lateral legs being parallel to each other and with the basic region defining the inner edge 16b of the circumferential rib 16 and whose shape can have different characteristics, depending on the construction used for the sealing element 20.
• the circumferential rib 16 presents a cross section in the approximate form of a horizontal V ⁇ V" , with a rounded vertex, defining the inner edge 16a of the circumferential rib 16 and having a lateral leg defining the upper face 16a of the circumferential rib 16 and which is preferably disposed orthogonally to the axis of the can when the sealing element 20 takes the form of the film 21 that hermetically seals the can.
• the closure arrangement Upon using a sealing element 20 in the form of a film 21 removably glued over the circumferential rib 16, the closure arrangement further comprises an overlid 30 which is formed in a single piece having a recessed median portion 31 to be housed in the interior of the tubular body 10, in a level higher than that of the circumferential rib 16 and by a peripheral portion 32 with a cross section in the approximate form of an inverted "U" and which is dimensioned to be tightly fitted over the upper edge 12 of the peripheral side wall 11 of the tubular body 10 of the can.
• the upper edge 12 of the peripheral side wall 11 of the can is bent outwardly, downwardly and inwardly, in order to define a tubular rib 17 externally incorporated to said upper edge 12, collaborating in the structural stiffening of the latter and defining a peripheral salience in this region of the can which, besides operating as a seating means for the peripheral portion 32 of the overlid 30, operates as an axial retention stop for peripheral portions of other types of sealing elements that can be fitted in the seat 15 of the can.
• the tubular rib 17 of the upper edge 12 of the peripheral side wall 11 of the can may present a circular or substantially circular cross section.
• peripheral portion 32 of said overlid 30 has a radially internal wall 32a which is dimensioned and configured to be telescopically and relatively tightly seated against the inner face of a portion of the peripheral side wall 11 of the can defined between the circumferential rib 16 and the upper edge 12.
• Said peripheral portion 32 further has a basic wall 32b to be seated on said upper edge 12 of the can, and a radially external wall 32c to be seated against the tubular rib 17, surrounding the latter.
• the radially external wall 32c of the peripheral portion 32 of the overlid 30 presents a free lower end edge that incorporates an external tubular curl 33 that imparts a better structural strength to the marginal portion of the overlid 30, which is generally molded in plastic material or the like.
• FIGs 5, 6 and 7 illustrate a construction for a can similar to that illustrated in figures 1-4, but using another type of sealing element 20 that dispenses the use of the film 21 glued over the circumferential rib 16.
• the circumferential rib 16 presents its inner edge 16b configured to define a preferably circular convex arc
• the sealing element 20 is defined by a lid 22 that comprises, in a single piece of metal foil or plastic material, a basic wall 23 and a peripheral wall 24 that presents an upper edge 25, to be seated on a portion of the peripheral side wall 11 of the tubular body 10 which is defined above the upper opening 14 of the can, and a circumferential recess 26 whose cross section is in the form of a concave arc turned radially outwardly, preferably in a circular development and which is configured to fit, therewithin, the inner edge 16b of the circumferential rib 16 upon the seating of the lid 22 on the seat 15.
• the circumferential rib 16 can present a cross section in any adequate form to define a seat for the seating and retention of the lid 22.
• the circumferential rib 16 presents the cross section in the approximate form of a horizontal "U” or "V” and the inner edge 16b of the circumferential rib 16 is formed by the basic portion of the "U” shaped profile or by the vertex of the "V" shaped profile.
• the inner edge 16b of the circumferential rib 16 is fitted, by elastic deformation of at least one of the peripheral side wall 11 of the can and the peripheral wall of the lid 22, in the interior of the circumferential recess 26 of the latter, allowing to obtain not only a fitting that hermetically seals the lid 22 to the seat 15, but also an effective and secure axial retention of the lid 22 to the tubular body 10 of the can.
• the tubular body 10 of the can is usually formed of a metal foil provided with a longitudinal seam, which is obtained by welding overlapping longitudinal edges of metal foil, there is the problem of obtaining an adequate sealing between the circumferential rib 16 and the circumferential recess 26 in the seaming region.
• a sealing element 50 made of an elastically deformable material compatible with the canned product, in order to accommodate the superficial alteration of the circumferential rib 16 in the longitudinally seamed region of the tubular body 10 .
• the elastically deformable sealing element 50 takes the form of an annular gasket covering at least part of the radial extension of the inner surface of the circumferential recess 26 of the lid 22, and said gasket can be formed in any suitable material, resinous or not, such as plastisol.
• the sealing element 50 can be dimensioned to surround only the inner edge 16b of the circumferential rib 16 or also, additionally, the upper face 16a of the latter and even a certain extension of the peripheral wall 24 of the lid 22.
• the lids 22 constructed in plastic material as illustrated in figure 6, depending on the characteristics of the seaming, of the plastic material of the lid, and of the product to be stored, the provision of the sealing element 50 may not be needed.
• the peripheral wall 24 of the lid 22 can be configured to present an annular radial portion 24a to be seated on the upper face 16a of the circumferential rib 16, and an axial upper portion 24b to be seated against the inner face of a portion of the peripheral side wall 11 of the can, defined between the circumferential rib 16 and its upper edge 12.
• This construction allows obtaining an even more effective sealing between the lid 22 and the region of the seat 15 of the tubular body 10 of the can.
• the upper edge 25 of the peripheral wall 11 of the lid 22 incorporates an external tubular rib 27 to be seated on the upper edge 12 of the peripheral side wall 11 of the tubular body 10 of the can upon the closing of the lid 22, by fitting the inner edge of the circumferential rib 16 in the interior of the circumferential recess 26 of the peripheral wall 11 of the lid 22.
• the external tubular rib 27 of the lid 22 is seated on the tubular rib 17 of the peripheral side wall 11 of the tubular body 10.
• the upper edge 25 of the peripheral wall 11 of the lid 22 may incorporate a seal 28 comprising a skirt 28a to be relatively tightly seated around the tubular body 10, immediately below the tubular rib 17 of its peripheral side wall 11, said lower skirt 28a being superiorly united to the upper edge 25 of the peripheral wall 11 of the lid 24 by means of bridges 28b to be manually broken when submitted to a certain force upon the first opening of the lid 22.
• the lower skirt 28a of the seal 28 is positioned below the tubular rib 17 and operates as a stop, which prevents the lid 22 from being removed without breaking the bridges 28b and liberating the seal 28.
• the circumferential rib 16 can be provided in a region of the peripheral side wall 11 of the tubular body 10 presenting a diameter that is substantially inferior to the diameter of the remainder of the tubular body 10 of the can, in order to make the seal 28 of the lid 22 to remain contained in the interior of the axial projection of the remainder of the tubular body 10.
• the tubular rib 17 is shaped and dimensioned so as to be maintained in a level above that in which the circumferential rib 16 is provided, allowing that the circumferential recess which forms the latter and which is defined in the peripheral side wall 11, to be visible in a lateral visualization of the can.
• the shape of the tubular rib 17, in the embodiments illustrated in figures 1-7 limits the structural reinforcement effect of the can, in the open upper portion of the tubular body 10, to the extension defined between the circumferential rib 16 and the upper edge 12.
• Figure 8 illustrates a constructive alternative for the tubular body 10 of the can, according to which the tubular rib 17 operates as a esthetic finishing element for the can and as a structural reinforcement element for the open upper portion of the tubular body 10 of the can.
• tubular rib 17 continues to be externally incorporated to the upper edge 12 of the peripheral side wall 11, but extending downwardly, beyond the circumferential rib
• tubular rib 17 is constructed to have its free lower end portion 17a inwardly and upwardly bent and disposed adjacent the peripheral side wall 11 of the tubular body 10, below the circumferential rib 16.
• the free lower end portion 17a of the tubular rib 17 presents an end region 17b, which is upwardly bent and laterally seated against the peripheral side wall 11 of the tubular body 10 of the can.
• the construction proposed herein allows the tubular rib 17 to completely cover the recess that forms the circumferential rib 16, giving an aspect of more integrity to the can and producing a structural reinforcement of larger axial extension.
• the tubular rib 17 is generally configured in an oblong shape in the direction of the can axis and presents a median extension 17c that is substantially parallel to the peripheral side wall 11 of the tubular body 10, in the region in which the circumferential rib 16 is incorporated, whereby the tubular rib 17 takes the form of a kind of strap surrounding the upper end portion of the can.
