Abstract
The container has a tubular body having a peripheral lateral wall provided with an upper end portion and a lower end portion defining an upper retention hook and a lower retention hook to which is double-seamed a lower end wall. An upper end wall is conformed to incorporate a peripheral upper skirt presenting an end edge defining an inverted U shaped upper closure hook to be seated onto the upper retention hook sandwiching an elastic sealing element therebetween. The upper closure hook and the upper retention hook and also a portion of the peripheral upper skirt and a confronting region of the upper end portion are deformed for seaming the upper closure hook onto the upper retention hook and to form, respectively, a retention rib and a retention groove which tightly fits the retention rib.
Description
- The present invention refers to a process to provide the upper closure of a container formed in metal sheet, such as a closed pail or other container comprising a peripheral lateral wall, with a cylindrical form or an inverted and slightly frusto-conical form and presenting an upper end portion and a lower end portion, to which respective end walls are attached.
- The containers of the type considered herein have their upper and lower end walls respectively and peripherally double-seamed in the upper end portion and lower end portion of the peripheral lateral wall, the upper end wall being provided with an a generally eccentric opening having a contour substantially smaller than that of the peripheral lateral wall, and with a gripping handle contained in the interior of the axial projection of the contour of the container, in order to allow the latter to be lifted by the gripping handle attached only to the upper end wall. The opening provided on the upper end wall is configured to define a seat to which is applied a lid generally formed in a plastic material.
- Due to the complexity of the double-seaming processes, which require the use of specific and generally expensive equipment, these double-seaming phases in the manufacture of the container considered herein are rarely carried out in the product filling facilities. Thus, the containers are closed in the manufacturer's facilities, by double-seaming the end walls to the peripheral lateral wall of the container, being then shipped to the facilities for filling the product to be commercialized. Since the containers are shipped with the end walls already double-seamed to the peripheral lateral wall, they cannot be fitted one inside the other, requiring to be arranged side-by-side and stacked in the transport vehicles and also in the storage places, both at the container manufacturer and at the filling facilities, requiring a physical space presenting an undesirable large volume in relation to the mass of the material, considerably increasing the shipping and storage costs and requiring special cares to transport these containers.
- Another drawback of these containers supplied to the responsible for the filling operation with the end walls already attached, generally by double-seaming, results from the fact that the filling can be only carried out through the opening of reduced dimension provided in the upper end wall. Thus, the time for filling the product is longer than that corresponding to the filling carried out without the upper end wall, as it occurs upon filling containers which are superiorly closed by a removable lid and provided with a suspension handle applied to the peripheral lateral wall and not to the lid.
- Aiming to overcome the inconveniences cited above, it was proposed a constructive solution object of the Brazilian patent application PI 0804305-1, “CONTAINER IN METAL SHEET”, filed on Oct. 9, 2008 by the present applicant. In this prior solution, the upper end wall can be easily, quickly, reliably and hermetically affixed to the peripheral lateral wall of the container by the filler of the product, without requiring double-seaming operations.
- According to said prior constructive solution of the same applicant, the upper peripheral edge of the peripheral lateral wall and the outer peripheral edge of the upper wall are conformed to allow them, through a simple and simultaneous deformation operation to be carried out by the filler, to be reliably and hermetically affixed to each other, generally with the aid of an elastic sealing element, in the form of a gasket compressed between the deformed edges of the peripheral lateral wall and the upper wall.
- In the applications in which a high degree of axial retention is required between the upper wall, provided with a suspension handle, and the peripheral lateral wall of the container, the upper end portion of the latter and the peripheral upper skirt of the upper end wall are provided with one or more circumferential ribs and grooves which cooperate with each other, upon fitting the upper end wall in the interior of the upper end portion of the peripheral lateral wall.
- Although the provision of the circumferential ribs and grooves leads to a substantial increase in the degree of axial retention of the upper end wall, as well as in the degree of hermeticity in said upper closure of the container, these ribs and grooves are provided separately in the skirt of the upper end wall and in the peripheral lateral wall of the container, by the manufacturer of the latter, requiring an undesirable dimensional precision in the manufacture of the two parts, in order to allow fitting them at the final closure of the container and obtaining the desired degrees of axial retention and additional sealing. This prior solution, although providing the advantages mentioned in said prior patent application of the same applicant, has the inconvenience of requiring costly manufacturing procedures.
- Due to the inconvenience commented above in relation to the prior solution, it is an object of the present invention to provide a process for closing a container in metal sheet, having a peripheral lateral wall, a lower end wall and an upper end wall which is provided with a small discharge opening and with a suspension handle and which can be easily, quickly, reliably and hermetically affixed to the peripheral lateral wall by the filler of the product to be packaged, without requiring double-seaming operations or costly operations for conforming the peripheral lateral wall and the upper end wall with reduced dimensional tolerances.
- The present process is applied for closing a container in metal sheet, of the type which comprises a tubular body formed by a peripheral lateral wall having an upper end portion and a lower end portion, to which respective upper and lower end walls are attached.
- According to the invention, the closing process comprises the steps of forming the tubular body in metal sheet, conforming its upper and lower end portions, so as to provide them, respectively, with an upper retention hook and with a lower retention hook, the lower retention hook being conventionally double-seamed to the lower end wall.
- The upper end wall is conformed in metal sheet, so as to present a peripheral upper skirt with its end edge being bent to configure an upper closure hook when the container is superiorly closed, still empty or already filled with the product.
- The upper closure hook and the upper retention hook and also the peripheral upper skirt of the upper end wall and the upper end portion of the peripheral lateral wall are then deformed together, in order to provide a seaming of said hooks, upon compressing an intermediary elastic sealing element, and also the formation of at least one outer circumferential retention rib in the peripheral upper skirt and a respective inner circumferential retention groove in the upper end portion of the peripheral lateral wall, tightly fitting the retention rib.
- The closing process proposed by the invention allows the upper end wall to be hermetically and reliably seamed to the tubular body of the container, without requiring the costly and complex operations of double-seaming or previously forming the retention ribs and grooves with expensive dimensional tolerances which hamper the manufacture and raise the costs of these containers.
- With the proposed process, the containers can be manufactured without the retention ribs and grooves and conveyed to be filled, with the upper end wall still as a separate piece, but with the lower end wall already duly double-seamed to the tubular body.
- In the proposed solution, the whole cross section of the still open upper end portion can be used during the filling, reducing the operation time before the operation of fitting and retaining the respective end wall in the interior of the peripheral lateral wall, by means of simple and concomitant axial and radial compression operations, to provide the deformation of both the closure hook and the upper retention hook and the concomitant formation of the circumferential rib and groove.
- In case the peripheral lateral wall is constructed so as to taper from one end portion to the other, generally from the upper end portion to the lower end portion, in a continuous or stepped manner, the containers can be stored and shipped without the upper end wall and in a condition in which they remain partially fitted one inside the other in stacks, allowing a substantial economy in storage and transportation volume until they are closed at the filling facility and, preferably, after the filling operation.
- The invention will be described below, with reference to the enclosed drawings, given by way of example of one of the possible embodiments of the invention and in which:
-
FIG. 1 represents a top plan view of the present container, with its peripheral lateral wall presenting a circular contour; -
FIG. 2 represents a partial diametrical sectional view of the container, illustrating the upper end wall and lower end wall affixed to the peripheral lateral wall, said section taken according to line II-II inFIG. 1 ; -
FIG. 3 represents an enlarged exploded detail of the region ofFIG. 2 which illustrates the fitting of the upper end wall in the upper end portion of the peripheral lateral wall, illustrating the form of the component parts before seating the upper end wall onto the peripheral lateral wall; -
FIG. 4 represents the same detail ofFIG. 3 , but illustrating the upper end wall already seated and only provisionally retained to the peripheral lateral wall; -
FIG. 5 represents a reduced lateral view of the container represented inFIG. 4 when a seaming device is applied thereto for compressing the closure hook and the upper retention hook, for forming the axial retention rib and groove. -
FIG. 5A represents a view similar to that ofFIG. 4 , but illustrating the application of the seaming device to provide the simultaneous deformation of the closure hook and upper retention hook and of the peripheral upper skirt together with the upper end portion of the peripheral lateral wall, so as to form the circumferential rib and groove to be tightly fitted together; -
FIG. 6 represents a view similar to that ofFIG. 5 , but illustrating only the container; and -
FIG. 7 represents a partial diametrical sectional view of two containers constructed according to the present process, deprived of the upper end wall and partially fitted one into the other. - The present closing process is applied to a container formed in metal sheet, usually tinplate, and comprising a tubular body C formed by a peripheral
lateral wall 10, with any polygonal cross section, usually circular and having anupper end portion 10 a and alower end portion 10 b, in which respectiveupper end wall 20 andlower end wall 30 are affixed. - According to the invention, after conforming a metal sheet portion to form the tubular body C, the latter is submitted to an operation for conforming the
upper end portion 10 a andlower end portion 10 b of the peripherallateral wall 10. - The conformation of the
upper end portion 10 a is made so as to provide, therein, an upperperipheral edge 10 c which is outwardly and downwardly bent, defining anupper retention hook 11 with a profile in the spa approximate form of an inverted U. - In the preferred form of the invention, the
upper retention hook 11 is conformed to present an innerlateral leg 11 a defined by part of theupper end portion 10 a of the peripherallateral wall 10, anarched base leg 11 b and an outerlateral leg 11 c which is convergent in relation to the innerlateral leg 11 a. The conformation of thelower end portion 10 b of the peripherallateral wall 10 is made to provide a lowerperipheral edge 10 d which is outwardly bent to define alower retention hook 12 which may present any known prior art configuration to allow the fixation, for example by double-seaming, of the likewise conformed peripheral edge of thelower end wall 30, also in metal sheet and with any conventional construction. The solution used to reliably and hermetically affix thelower end wall 30 to the tubular body C is not a particular aspect of the present process, which fixation may be carried out at the manufacturer's facilities by any adequate method. - After conforming the tubular body C and the
upper retention hook 11 and thelower retention hook 12, a peripheral edge of thelower end wall 30 is affixed to the tubular body C, generally by double-seaming. - Concomitantly to the formation of the tubular body C and to the closing of its
lower end wall 30, a metal sheet portion is conformed to define the upper end wall comprising amedian panel 21, which is optionally provided with well known prior art stiffening circumferential ridges, and with a peripheralupper skirt 22, projecting axially outwardly and which is configured to be tightly fitted, under interference, in the interior of theupper end portion 10 a of the peripherallateral wall 10. - The peripheral
upper skirt 22 has anend edge 22 c which is, outwardly, downwardly and inwardly bent, so as to define aclosure hook 23 with a profile in the approximate form of an inverted U. - In the preferred and illustrated form, the
closure hook 23 is conformed to present an innerlateral portion 23 a, defined by an upper part of the peripheralupper skirt 22 of theupper end wall 20, anarched base portion 23 b and an outerlateral portion 23 c which is convergent in relation to the innerlateral portion 23 a and which internally incorporates anend flange 23 d which projects upwardly. - According to the process of the invention, the peripheral
upper skirt 22 of theupper end wall 20 can be then fitted and seated in the interior of theupper end portion 10 a of the peripherallateral wall 10, with the container being empty or already filled with the product, said fitting being carried out to seat theclosure hook 23 onto theupper retention hook 11, sandwiching anelastic sealing element 40 previously provided between saidhooks FIGS. 4 , 5A and 6). - In the solution illustrated in the drawings, the fitting of the
closure hook 23 onto theupper retention hook 11 is made so that thearched base portion 23 b of the former is seated on thearched base leg 11 b of the latter, with theelastic sealing element 40, for example a plastisol film, being disposed between saidarched base portion 23 b andarched base leg 11 b. - As illustrated, the
elastic sealing element 40 is preferably applied under thearched base portion 23 b of theclosure hook 23, so as to be seated against thearched base leg 11 b of theupper retention hook 11 upon fitting and seating theupper end wall 20 in the interior of theupper end portion 10 a of the peripherallateral wall 10. - The exploded view of
FIG. 3 illustrates the form imparted to the parts before closing the container. In this stage, the diameter of the free end edge of the outerlateral leg 11 c of theupper retention hook 11 is slightly smaller than the diameter of the free upper edge of theend flange 23 d which projects upwardly outwardly inclined. Thus, upon seating theupper end wall 20 in the condition illustrated inFIG. 4 , both said parts suffer an elastic deformation to allow theend flange 23 d to be fitted under the free end edge of the outerlateral leg 11 c of theupper retention hook 11. - Being the container ready to be closed, generally after having already been filled with the product to be packaged, with the
upper end wall 20 being already fitted and seated in the interior of theupper end portion 10 a of the peripherallateral wall 10, theclosure hook 23 and theupper retention hook 11 and also a portion of the peripheralupper skirt 22 and a confronting region of theupper end portion 10 a may be submitted to a joint deformation operation, so as to provide the seaming of theclosure hook 23 onto theupper retention hook 11, compressing theelastic sealing element 40 therebetween and further forming at least one outercircumferential retention rib 24 in the peripheralupper skirt 22 and one innercircumferential retention groove 14 in theupper end portion 10 a of the peripherallateral wall 10, saidretention rib 24 being tightly fitted in the interior of theretention groove 14, guaranteeing a tight and reliable coupling between the parts of tubular body C andupper end wall 20, without requiring especial manufacturing cares for allowing theretention rib 24 to perfectly follow the inner contour of theretention groove 14. - The deformation of both the
closure hook 23 and theupper retention hook 11 is obtained by applying an inward and upward radial force, in opposition to the application of an outward radial force, against the peripheralupper skirt 22 and theupper end portion 10 a of the peripherallateral wall 10, in order to simultaneously form theretention rib 24 and theretention groove 14. - In the preferred and illustrated construction, the fitting of the
closure hook 23 onto theupper retention hook 11 is made so that thearched base portion 23 b of theclosure hook 23 is seated onto thearched base leg 11 b of theupper retention hook 11, the seaming of theclosure hook 23 onto theupper retention hook 11 also being made so as to seat the innerlateral portion 23 a,arched base portion 23 b and outerlateral portion 23 c of theclosure hook 23 respectively against the innerlateral leg 11 a,arched base leg 11 b and outerlateral leg 11 c of theupper retention hook 11, compressing theelastic sealing element 40 and having theend flange 23 d projecting upwardly to the interior of theupper retention hook 11, between the outerlateral leg 11 b and the innerlateral leg 11 a of the latter. - As illustrated in
FIGS. 5 and 5A , the deformations for seaming the hooks and for forming theretention rib 24 and theretention groove 14 can be easily carried out after the filling of the product, by means of aseaming device 50 which comprises a plurality of outerperipheral fingers 51 and a plurality of innerperipheral fingers 52, said outerperipheral fingers 51 and innerperipheral fingers 52 being configured to jointly define circular alignments, with a variable diameter as a function of the operation of theseaming device 50, and to act simultaneously against the hooks from the outer side of the container and against the peripheralupper skirt 22, so as to simultaneously produce the seaming deformation of both theupper closure hook 23 and theupper retention hook 11 and the formation of both theretention rib 24 and theretention groove 14. As can be noted inFIG. 5A , the outerperipheral fingers 51 and innerperipheral fingers 52 are configured to impart, to the respective parts against which they are seated, the desired conformation to obtain both the seaming of the hooks and the fitting between the peripheralupper skirt 22 and theupper end portion 10 a of the peripherallateral wall 10, guaranteeing a strong axial retention between theupper end wall 20 and the tubular body C of the container, besides establishing a sealing region additionally to that defined by the seaming of theclosure hook 23 andupper retention hook 11, with the provision of theelastic sealing element 40 therebetween. - Further as illustrated, after finishing the deformation of the
closure hook 23 andupper retention hook 11, the outerlateral leg 11 c of theupper retention hook 11 and the outerlateral portion 23 c of the closure hook assume a substantially rectilinear and downwardly and radially inwardly inclined profile, guaranteeing a strong, reliable and tight fixation of theupper end wall 20 to the peripherallateral wall 10. - With the purpose of facilitating the accommodation of the two parts to be fixed to each other, as well as the operations of plastic deformation of the metal sheet upon the initial and final formation of the two hooks, the inner
lateral leg 11 a of theupper retention hook 11 and the innerlateral portion 23 a of theclosure hook 23 are initially conformed to present a profile that is substantially rectilinear and slightly inclined upwardly and radially outwardly. - According to the illustrated embodiment, the
retention rib 24 and theretention groove 14 are constructed so as to present a cross section with the approximate form of a rounded V, in a convex and in a concave arc, respectively. - Depending on the characteristics of the application of the
elastic sealing element 40, it may have a portion of its extension penetrating and being compressed between the innerlateral leg 11 a and the innerlateral portion 23 a of theupper retention hook 11 and of theclosure hook 23, respectively, as illustrated inFIG. 5 . - Considering that the construction of the present container aims at obtaining a closure which is easily executed, but which can comply with the safety requirements applied to the containers for dangerous products, the peripheral lateral wall can be provided with energy absorbing means by controlled plastic deformation. Thus, the peripheral
lateral wall 10 can present two regions respectively adjacent to theupper end portion 10 a andlower end portion 10 b, each occupying about 10% to 15% of the height of the peripherallateral wall 10 and conformed in a plurality ofcircumferential grooves 10 e presenting a profile in the form of a laid V with a rounded apex. These regions present a pleated structure which tends to deform before an undue deformation of the container occurs in the regions in which theend walls lateral wall 10. - As can be observed in
FIGS. 1 and 2 , considering that the twoupper end wall 20 andlower end wall 30 are affixed, in a non-removable manner, to the peripherallateral wall 10, themedian panel 21 of theupper end wall 20 is provided with a generallyeccentric opening 21 a of smaller diameter, and with agripping handle 60 generally positioned in the central region of saidupper end wall 20, the grippinghandle 60 being integrally affixed in saidupper end wall 20, so as to allow the container, even if filled, to be lifted by said grippinghandle 60. In this type of construction, the smaller diameter opening 21 a is usually closed by a removable lid; preferably constructed in a plastic material and which is not illustrated herein, as it forms no part of the present invention. - As already previously mentioned and further illustrated in
FIG. 7 of the enclosed drawings, the peripherallateral wall 10 of the container can be constructed to allow the partial telescopic fitting between two stacked containers. In the illustrated embodiment, the peripherallateral wall 10 has an inverted and slightly frusto-conical form, the smaller base coinciding with thelower end wall 30 and the larger base being preferably situated in a plane axially spaced back in relation to the mounting plane of theupper end wall 20 and in which the peripherallateral wall 10 is deformed to define an outercircumferential projection 19. - With this construction, a container can be telescopically fitted inside another inferiorly disposed container deprived of the upper end wall, this fitting, as illustrated in
FIG. 7 , being carried out until the outercircumferential projection 19 is seated onto the free edge of theupper end portion 10 a of the peripherallateral wall 10 of the inferiorly disposed container, allowing the thus stacked containers to occupy a total volume substantially inferior to the volume that would be occupied with the same number of inferiorly and superiorly closed containers stacked one on top of the other. With this partial fitting arrangement, the containers can be stored and shipped with a great economy in volume and, accordingly, in cost. - While only one embodiment of the invention has been illustrated herein, it should be understood that the present closing process can suffer alterations in the deformation characteristics of the involved parts, without departing from the constructive concept defined in the claims that accompany the present specification.
