CLOSING AND SUSPENSION ARRANGEMENT FOR CANS

Field of invention

The present invention relates to a closure and suspension arrangement to be applied to cans formed in sheet metal and comprising a portion of a tubular body, generally of circular section and carrying a bottom wall, a portion of the upper neck, of contour smaller than that of the body portion and a transition portion joining the body and neck portions and having an extreme edge that defines the outline of an upper opening of the can, an opening in which a removable lid is fitted.

Background of the invention

Tubular tin foil cans are well known in the art and comprise a body portion, circular or polygonal cross section, inferiorly closed by a bottom wall and superiorly joined, by a transition portion, to a neck portion whose section transverse and whose height is reduced in relation to those of the body portion.

The provision of the transition portion in the upper region of the can provides a considerable increase in the structural strength of the latter, allowing the elimination of the upper annular wall, with the upper opening of the can corresponding to the internal cross section of the neck portion. In this construction, it is sufficient that the extreme upper edge of the can, that is, the neck portion, be curved, or otherwise worked, to form a ferrule or external peripheral shoulder, bypassing the upper opening of the can and defining, together with the extreme upper edge of the latter, a seat for laying a removable cover, comprising a portion of the panel that incorporates a peripheral tubular portion to be fitted, with interference, in the upper opening, inside the neck portion, said peripheral tubular portion having a free upper edge that is curved, or otherwise worked, to form an external peripheral ferrule or rib, semi-tubular in shape, inferiorly open and housing an annular gasket, which is seated and compressed against the shoulder outer periphery of the neck portion, when fitting the peripheral tubular portion of the lid into the top opening of the can.

This construction of the prior art allows the elimination of the upper annular wall and the formation of an initial tubular body, with a metal sheet of usual thickness, for example, with about 0.2lmm to about 0.27mm, for cans of 3, δ liters, and presenting one to that of the portion to be observed in the applicant), DE the peripheral rib corresponding cross section of the neck. This construction can documents PCT / BR2011 / 000166 (from

4021211 Al and still FR 2,104,673, the latter showing a can devoid of the neck portion.

These cans may have their closing elements also comprising a retaining ring, of plastic material, having an upper annular portion to be seated on the outer peripheral rib of the lid and a portion of pendant skirt, involving the outer peripheral of the lid and the external shoulder the neck portion and incorporating an internal circumferential projection to be seated and axially locked under the outer peripheral shoulder of the neck portion, to retain the outer circumferential rib of the cap, seated against the outer peripheral shoulder of the neck portion, as described and illustrated in the already cited document PCT / BR2011 / 000166.

Although the retaining ring can be constructed in such a way as to make it difficult to remove the lid without evidencing the opening of the can and access to its contents, the known constructions do not provide an effective tamper-proof seal, simple construction and necessarily be broken to allow and evidence the first opening of the can. Another deficiency of the known constructions, for the type of can considered here, results from the fact that they do not have a simple construction suspension arrangement, of relatively low cost and easy assembly to the body portion of the can and that is operatively associated with the ring. retention, in order to define an inviolability seal and avoid the usual complex and costly constructions for forming the seal in a retaining ring that defines an element without any operational association with the suspension arrangement.

Yet another deficiency of the known solutions concerns the need to provide a stable stacking and without interlocking of the retaining rings and the suspension rings in the feed magazines of them in the mechanized assembly equipment of the mentioned retaining and suspension rings in the peripheral rib. of the lid and around the neck portion of the can, respectively.

Summary of the invention

Due to the limitations of the known solutions, it is an objective of the present invention to provide a closure and suspension arrangement for a can of the type provided with a neck portion of reduced section and that presents a simple construction that allows not only a tight and secure closure of the can with a high degree of tightness and with the provision of a seal capable of showing a first opening of the lid, as well as an easy manual suspension of the can in any of its conditions with a closed lid or with the lid removed. The invention also has the objective of providing a closure and suspension arrangement as mentioned above and that makes it easier and safer to mechanize the assembly of closure means and suspension means in the lid and the can, respectively.

Yet another objective of the invention is to provide a closing and suspension arrangement, as mentioned above, which does not subject the outer peripheral rib of the lid to the forces to be applied to the latter, during its closing by fitting in the upper opening. of the can.

closure and suspension arrangement in question is applied to cans that comprise: a body portion; a neck portion having an upper end edge defining an upper opening of the can and incorporating an external peripheral shoulder; a transition portion, joining the body and neck portions; and a cap including a peripheral tubular portion to be fitted in the upper opening and having an upper edge carrying an external peripheral rib.

According to the invention, the closing and suspension arrangement comprises: a retaining ring, made of plastic material, having an upper annular portion seated and retained on the outer peripheral rib and surrounding the latter upper and laterally, a pendant skirt portion involving, externally and justly, the external peripheral rib and the external peripheral shoulder and incorporating an internal circumferential projection, to be seated and axially locked under the external peripheral shoulder; and a suspension ring, in plastic material, surrounding the neck portion, carrying a handle strap and being ascending and descendingly locked, respectively, against the external peripheral shoulder and against the transition portion, and presenting an upper peripheral channel, which it is externally limited by a surrounding wall and into which the lower tubular projection of the retaining ring is fitted and upwardly locked, the surrounding wall being elastically deformable outwardly, to release the upward displacement of said lower tubular projection and the removal of the cover, being the surrounding wall superiorly joined, in one piece and through breakable connection means, to a detachable seal band, peripherally surrounding a lower region of the pendant skirt portion of the retaining ring.

The construction defined above allows the closure of the can to be achieved by a simple construction, with the axial locking of the lid by the retaining ring and the provision of a first opening evidence seal, defined by the cooperation of the retaining ring with the retaining ring. suspension that carries a handle strap and that is partially ruptured1 to allow the release of the retaining ring and the removal of the cover, preferably with the use of a simple lever tool insertable between the lower region of the pendant skirt portion of the retaining ring and the wall surrounding the suspension ring, after removing the seal band.

Description of the invention

As previously mentioned in the accompanying drawings, the arrangement described and illustrated in the closing and hanging ones, proposed by the invention, is applied to a can 10 formed in metallic foil, usually tinplate, presenting a cross section, generally circular, but which can be polygonal , although this configuration is not illustrated in the drawings.

The can 10, of tubular shape, comprises: a body portion 11, on whose lower extreme edge 11a is fixed, generally by seaming, the peripheral edge of a bottom wall 12; a neck portion 13 having a concentric contour, similar and reduced in relation to that of body portion 11 and an upper end edge 13a defining the outline of an upper opening A for can 10; and a transition portion 14 with an inclined profile in relation to the geometric axis of the can 10 and joining the body 11 and neck 13 portions.

The upper extreme edge 13a of the neck portion 13 incorporates an external peripheral shoulder 15. In the condition illustrated, the external peripheral shoulder 15 takes the form of a tubular cross-section ferrule, obtained by folding the metal sheet, radially outwards, in the region of the upper extreme edge 13a. In the drawings, the cross section of the ferrule is circular, it should be understood that a peripheral shoulder may be formed with different cross sections, tubular or not.

The formation of the body portion 11 is initiated by the formation of a tubular body having a cross section corresponding to that of the neck portion 13 and which is then radially expanded, in part of its height, to define the body 11 and transition portions 14, according to methods known in the art. Preferably, the transition portion 14 is inferiorly joined to the body portion 11 by a convex arc junction region 14a and superiorly joined to the neck portion 13 by a concave arc junction region 14b.

The can 10 further comprises a lid 20 formed in a single piece of stamped metal foil, having a portion of panel 21, occupying a large part of the cross-sectional area of the upper opening A and incorporating a peripheral tubular portion 22, which is configured and dimensioned to fit snugly and with interference in the upper opening A, inside the neck portion 13.

Said peripheral tubular portion 22 has an upper edge 22a in which an external peripheral rib 25 is incorporated, configured to be seated on the outer peripheral shoulder 15, which is provided on the upper extreme edge 13a of the neck portion 13. As illustrated, the cap 20 is preferably constructed with its panel portion 21 incorporating a pendant skirt 21a, generally trunk-conical, which forms, with the peripheral tubular portion 22, a peripheral channel 24, radially separating the panel portion 21 from the peripheral tubular portion 22 the panel portion 21 being arranged in an elevated plane in relation to the bottom wall 24a of the peripheral channel 24.

According to an aspect of the invention, the outer peripheral rib 25 has a partially tubular shape, inferiorly open and having: a radially inner edge 25a which is joined to the upper edge 22a of the peripheral tubular portion 22 of the cap 20 by an annular step 26 projecting out of said peripheral tubular portion 22; and a radially outer edge 25b, away from the radially inner edge 25a, the outer peripheral rib 25 carrying, inside, an annular gasket 30, preferably in the form of a resin cord, for example Plastisol, molded within the rib outer periphery 25 of cover 20.

The ring gasket 30 is configured, inside the outer peripheral rib 25, to be seated and compressed, against the outer peripheral shoulder 15 of the neck portion 13, when the lid 20 is fitted in the upper opening A of the can and the seat of the step ring 26 on the external peripheral shoulder 15 of the neck portion 13.

Although the drawings illustrate only an outer peripheral rib 25 in the form of a partially tubular ferrule, with a cross-section in a circular arc, it should be understood that other forms of cross-section that are not perfectly circular can be used.

According to the construction illustrated, the outer peripheral rib 25 has the projection of its edges, radially internal 25a and radially external 25b, in the axial direction of the can, arranged in a secant manner to the radially innermost half and the radially outermost half, respectively, the contour of the external peripheral shoulder 15 of the neck portion 13.

Also according to the illustrated construction, the radially inner edge 25a and the radially outer edge 25b of the outer peripheral rib 25 define, between themselves, a tangent or slightly drying alignment to the upper half of the outer peripheral shoulder 15 contour of the neck portion 13 This constructive form allows the upper portion of the external peripheral shoulder 15 to penetrate, slightly, inside the lower contour of the external peripheral rib 25, compressing the ring gasket 30 and ensuring a high degree of tightness when closing the cover 20, when it is closed. fit in the top opening A of the can.

In order to print a certain degree of interference between the annular gasket 30 and the upper portion of the external peripheral shoulder 15, the annular gasket 30 is configured to be inferiorly tangent or sectioned by the alignment defined by the edges, radially internal 25a and radially external 25b, of the peripheral rib cover 25 of the cover 20.

As shown in the drawing figures, the closure arrangement in question further comprises a retaining ring 40, in a single piece of plastic material and having: an upper annular portion 41 to be seated and retained on the outer peripheral rib 25 of the lid 20, upper and laterally surrounding said external peripheral rib 25; a peripheral skirt portion 42 pending from the upper annular portion 41, tightly and laterally surrounding the outer peripheral rib 25 of the cap 20 and the outer peripheral shoulder 15 of the neck portion 13 and incorporating an internal circumferential projection 43, a be seated and axially locked under the external peripheral shoulder 15 of the neck portion 13.

In the illustrated configuration, the internal circumferential projection 43 has a ramp-shaped profile inclined downwards and radially inward, to define a kind of tooth acting under the outer peripheral shoulder 15 of the neck 13, to provide a secure axial locking of the cap 20 to the body 10 of the can. In order for the retaining ring 40 to remain securely attached to the lid 20, the peripheral skirt 42 can also incorporate, inside, a peripheral cord 4 4 configured to be fitted, justly, under the radially outer edge 25b of the peripheral rib external 25. With this, the retaining ring 40 is incorporated into the lid 20 before it is fitted in the upper opening A of the can, after the latter can be filled with the product to be canned.

As illustrated, the peripheral skirt portion 42 is provided, in part of its height and from a lower edge 42b of said peripheral skirt, with an external recess 42a, the function of which will be described below.

In the illustrated constructive form, the retaining ring 40 also incorporates, in its upper annular portion 41, a first upper tubular projection 46, radially recessed in relation to the external contour of the retaining ring 40, in order to define, with the upper annular portion 41, a peripheral step 46a on which the lower peripheral edge 11a rests, that is, the recess of the bottom wall 12 of another identical can, supported on the first in a pile of said cans, as shown in figure 2.

retaining ring 40 may further incorporate, in its upper annular portion 41, a second upper tubular projection 47, radially recessed in relation to the first upper tubular projection 46 and having a height generally greater than that of the latter and whose function will be explained later.

According to the invention, the peripheral skirt 42 of the retaining ring 40 further incorporates a lower tubular projection 48 defined as a single circumferential band or as a plurality of circumferential band portions and incorporating, along its extensions, an external lower tooth 48a, facing upwards and inferiorly configured in the form of a ramp and whose function will be described later.

Still according to the invention, the arrangement additionally comprises a suspension ring 50, in plastic material, which is assembled so as to surround the neck portion 13 of the can, generally after the formation of the latter and before it is sent to the bottler. The suspension ring 50 is ascending and descendingly locked, respectively, against the outer peripheral shoulder 15 and against the transition portion 14, being axially retained between these two portions of the can.

In the illustrated configuration, the suspension ring 50 incorporates an upper projection 51, the extreme edge of which 51a is seated under the outer peripheral shoulder 15, and a lower projection 52, whose extreme edge 52a is positioned adjacent to the lower region of the transition portion. 14 of the can, and can be seated against the latter. The retaining ring 50 has an inner lower portion 50a configured to be seated against the transition portion 14 and against it locked downwards.

The suspension ring 50 has a peripheral upper channel 53 which is externally limited by a surrounding wall 54 provided with an internal upper tooth 54a, facing downwards and which can be superiorly configured on a ramp. Inside the upper peripheral channel 53, the lower tubular projection 48 of the retaining ring 40 is inserted and upwardly retained. The insertion of the lower tubular projection 48 in the upper peripheral channel 53 is carried out only when the can is closed after filling, by laying the lid 20, already carrying the retaining ring 40, in the upper opening A of the can. Said fitting of the lower tubular projection 48 is obtained by passing its external lower tooth 48a through the internal upper tooth 54a of the surrounding wall 54 of the suspension ring

50, which is elastically deformed outwardly and returned to its resting position, in which its tooth 54a starts to operate as a stop for the external lower tooth 48a of the lower tubular projection 48. This arrangement prevents the retaining ring 40 be moved axially upwards to release the cover 20.

In the construction now proposed, the surrounding wall 54 is superiorly joined, in a single piece and through breakable connection means 55c, to a detachable seal strap 56, interrupted by an axial slit 56a and peripherally surrounding a lower region of the skirt portion peripheral 42 of the retaining ring 40. The sealing strap 56 has an enlarged end portion 56b, adjacent to the axial slot 56a of the latter and which is loosely housed within the outer recess 42a of the peripheral skirt portion 42.

Thus, after removing the seal band 56, the wall 54 of the suspension ring 50 can be elastically deformed outwardly, to release the engagement between the inner radial tooth 54a of the surrounding wall 54 and the outer radial tooth 48a of the tubular projection lower 48 of the retaining ring 40, allowing upward displacement of said lower tubular projection 48 and removal of the cap 20.

To facilitate opening of the lid 20 after removing the sealing band 56, the wall 54 of the suspension ring 50 has an upper edge 54b that maintains an axial clearance with respect to a lower edge 42b of the peripheral skirt portion 42 of the ring retainer 40, sufficient to allow the insertion of a manual lever means in said axial clearance after removal of the sealing band 56.

Thus, for the cap 20 to be released, it is necessary to manually break the extended end portion 56b of the sealing band 56, and then the rest of the latter, so that the wall 54 of the suspension ring 50 can be removed. elastically deformed outwardly, to release the engagement of the radial teeth 54a and 48a, allowing the lower tubular projection 48 of the retaining ring 40 to be displaced axially upwards, together with the retaining ring 40 and the cap 20, opening the can.

Thus, for the first opening of the can to occur, it is necessary to break the seal band 56 of the suspension ring 50, a break which clearly demonstrates the violation of the can seal.

Also according to the invention, the suspension ring 50 incorporates, externally and in its lower projection 52, in opposite regions and generally in one piece, two radial pins | 55, preferably each provided with a respective enlarged head 55a and the suspension arrangement further comprises a handle handle 60, in general U shape, formed of any suitable material, such as plastic, having extreme portions 61 respectively hinged on the radial pins 55 and a median portion 62, preferably enlarged, the handle handle 60 being angularly movable, around the geometric axis common to the two radial pins 55, between an inoperative position, in which it is positioned laterally and externally to a respective lateral extension of the neck portion 13 of the can and the suspension ring 50, generally corresponding to half the perimeter of the neck portion 13 and the suspension ring 50, and an operating position in which it is positioned over the can. The operating positions of the handle are shown in figures 4 and 5.

Each extreme portion 61, preferably enlarged, of the handle handle 60, is provided with a through opening 63 through which a respective radial pin 55 of the suspension ring 50 is bearing. The through opening 63 has a width, in the direction transverse to the extension of the handle loop 60, sufficient to handle the radial pin 55 in a fair way and in said direction, and a length, in the longitudinal direction of the handle loop 60, sufficient to handle the radial pin 55, both with the handle loop 50 in the inoperative position, as with the handle handle 60 in angular displacement from the inoperative position to the operating position.

The through opening 63, of each extreme portion 61 of the handle loop 60, has opposite lateral edges 63a, parallel and straight, against which opposite regions of the generally circular cross section of the respective radial pin 55 are seated. .

The through opening 63 also has an extreme outer edge 63b, against which the respective radial pin 55 is seated, when the handle handle 60 is in the operating position and suspending the can, as shown in figures 3 and 5.

In order to operate properly, each radial pin 55 incorporates an enlarged head 55a with a larger contour than the width of the through openings 63, each of which has an internal end, opposite the extreme outer edge 63b and open to an enlarged hole 64 with a contour sized to allow the passage of the enlarged head 55a from the radial pin 55, generally with little elastic deformation of the enlarged head 55a or the through opening 63.

Although not shown here, it should be understood that the handle handle 60 may have each through opening 63 showing opposite, parallel and straight lateral edges, while each radial pin 55 may have a polygonal cross section dimensioned to cooperate with the opposite edges of each respective through opening 63 when the handle loop 60 is in its inoperative position, allowing stabilization of the handle loop 60 in that position, as defined in the patent application PI 1100010-4 of the applicant.

As the suspension ring 50 is disposed axially away from the outer peripheral shoulder 15 of the can, the through opening 63, in each extreme portion 61 of the handle handle 60, takes the form of an oblong slot, longitudinally disposed in the handle handle 60, to allow the latter to be displaced radially in relation to the geometric axis of the two radial pins 55, to increase their angular displacement radius, avoiding any interference contact with the retaining ring 40 or the outer peripheral shoulder 15 of the neck portion 13, when said handle is moved between inoperative and operating positions.

As shown in figure 6, the suspension rings 50 are constructed to allow their stable stacking in a magazine of an assembly machine of said suspension rings 50 around the neck portion 13 in a can of the type considered here. For this purpose, the lower projection 52 of each suspension ring 50 is dimensioned in width and height to be fitted within the peripheral upper channel 53 of another suspension ring 50 disposed immediately below in a stack of said rings. Said fitting of the lower projection 52 is made without deformation of the surrounding wall 54, serving only as a guide element to stabilize the column of suspension rings 50 stacked in a magazine or in stacks to be fed to a magazine.

As shown in figure 7, the retaining rings 40 are built to allow their stable stacking in a magazine of an assembly machine, around the neck portion 13 in a can already filled and of the type considered here, of said retaining rings 40 already incorporated into each respective cap 20. To this end, the lower tubular projection 48 of the retaining ring 40 is seated on the first upper projection 46 of another retaining ring 40 disposed under the first, in a stack of retaining rings 40 already incorporated, each one to a respective cap 20, with the second upper projection 4 8 of said other retaining ring 4 acting as an external guide stop for the lower region of the peripheral tubular portion 22 of the cap 20 incorporated to said other ring retention 40.

Although only one embodiment for the closure and suspension arrangement in question has been illustrated, it should be understood that different changes in shape and layout may be made to its component parts, without these changes departing from the constructive concept defined in the accompanying claims this report.
