Definitions
- a plastic release strip is included in a seam formed between a metal end closure and a metal container body to serve as a seam holding and release element, the plastic strip being manually removable without destruction or mutilation of either the container body or the end closure.
- the seam release strip at its top edge, abuts a projection or head formed by an inner marginal portion of a doubled-back longitudinal end section of the body side wall, exteriorly to the side wall, to preclude displacement of the seam release strip and thereby ensure seam integrity particularly for products contained under pressure.
- the end closure has a skirt extending longitudinally from the open end of the container body and having an inwardly indented annular portion which compresses the portion of the strip that abuts the bead to thereby facilitate sealing of the open end of the container body by the end closure and further enhance the integrity of the seam.
- the skirt of the end closure also has a peripheral, annular, inwardly-directed curled hem which compresses the portion of the strip that engages an exterior annular surface of the body side to thereby cause that portion to further frictionally engage the sharp raw metal edge on an outer marginal portion of the double-back end body by the end closure and still further enhance the integrity of the seam.
- This invention relates to easy-opening containers and has particular reference to a container construction wherein a removable plastic strip is incorporated in the end seam of a container to provide for the complete detachment of the end closure member of the container without destruction or mutilation of either the l container body or the top closure member.
- the present invention utilizes a plastic seam release strip to provide'an easy-opening container construction which avoids all of the disadvantages of these other constructions in that it makes possible a full-open container in which the complete top closure member can be readily detached by the consumer without tools and without any mutilation or tearing of either the container body or the top closure member.
- the arrange ment also permits ready reclosure during the useful life of the container. 1
- a plastic seam release strip of this type has been used in connection with the seamingof a metal end closure to a container body which is used for holding non-pressurized products and made of compressible or non-rigid materials, for example, fiber or plastic materials, wherein, after assembly of the seam, a portion of the plastic strip is indented into the compressible material of the container body by a flange portion of the metal end closure, thereby causing a compression thinning of a portion of the container body and of a portion of the plastic strip in area of the seam.
- the metal end closure is securely locked in place on the end of the container body in what may be designated as an indented or crimped seam.
- a plastic seam release strip incorporated in a seam of this type on a container body made of compressible material is disclosed in US. Pat. Nos. 3,330,436, 3,336,269 and 3,409,200.
- sealing rings of resilient materials have been incorporated into the seam between a metal end closure and a metal container body, for example, as disclosed in British Patent Specification Nos. 523,202 and 955,579 and Japanese Utility Model Publication No. 10362/1923.
- the present invention which discloses novel structural features over the prior art, is particularly useful for containers made of materials not generally considered compressible, for example, sheet metal, and which may be used for holding pressurized products, including products temporarily pressurized during processing as is conventional in food canning.
- novel structural features of the present invention and the novel cooperation between those features ensure the integrity of the seam formed by the end closure and the container body under pressurized conditions.
- a projection or head formed by an inner marginal portion of a doubled-back longitudinal end section of body side wall, which serves as an abutment or stop for the plastic seam release strip to prevent the latter from sliding out of position on the container body.
- the projection also serves to align the seam release strip and maintain its proper position during assembly. Further, when used with sheet metal containers, the projection or bead functions to eliminate exposure of sharp edges after opening.
- Seam integrity is further enhanced by the frictional engagement of a portion of the seam release strip with the sharp raw metal edge formed on an outer marginal portion of the doubled-back longitudinal end section of the body side wall when this portion of the strip is compressed by a peripheral, inwardly-directed curled hem formed on a skirt of the end closure.
- seam integrity is enhanced by an inwardly indented annular portion of the skirt on the end closure which-compresses the portion of the strip that abuts the bead formed by the inner marginal portion of the doubled-back end section of the body side wall.
- Seam integrity and subsequent reclosure of the end closure on the container body is also enhanced by a possible interference contact occurring between the bead formed by the inner marginal portion of the doubled-back end section of the body side wall and the inwardly indented annular portion of the skirt on the end closure when the respective portions displace toward one another under pressurized conditions within the container body.
- the present invention relates to a container body, having a longitudinally-extending body side wall, with an open end in the container body being defined by a longitudinal end section of the body side wall doubledback onto a portion of the remaining side wall and partially engaged with an annular exterior surface portion of the side wall.
- An inner marginal portion of the doubled-back end section in the form of a projection or bead extends annularly and exteriorly about the open end of the container body.
- An outer marginal portion of the doubled-back end section is displaced from the open end of the container body and'engaged with the annular exterior surface portion of the body side wall, the outer marginal portion having a sharp raw edge on its periphery.
- a plastic seam release strip is securely maintained about, and in a predetermined position displaced longitudinally from, the open end of the container body. This position of the strip is maintained by one annular portion of the strip being releasably adhered to another exterior surface portion of the side wall and another annular portion of the strip being abutted with the inner marginal portion of the doubled-back end section of the side wall. Still further,
- an end closure having a container end defining portion which merges into an annular peripheral skirt, is seamed to the open end of the container body with the plastic strip serving as an integral holding member being novelly incorporated therebetween.
- the skirt of the end closure extends longitudinally from the open end of the container body and has a radially inwardlyindented portion which compresses the annular portion of the strip that abuts the inner marginal portion of the doubled-back end section of the body side wall to thereby facilitate the sealing of the open end of the container body by the end closure.
- skirt as a peripheral, inwardly-curled hem which compresses the portion of the strip that engages the sharp raw edge of the outer marginal portion of the doubled-back end section to cause frictional engagement of this strip portion with the sharp raw edge and thereby further facilitate sealing of the open end of the container body by the end closure.
- FIG. I is a perspective view of a completed container having a plastic seam release strip formed as an integral holding member securing the top end closure to the container body;
- FIG. 2 is an enlarged side elevation of the upper portion of the container shown in FIG. 1 showing the seam release strip partially pulled out of the seam during the container opening operation;
- FIG. 3 is an enlarged sectional detail taken substantially along the line 3-3 in FIG. 1 showing a cross-section of the assembled unit
- FIG. 4 is an enlarged sectional detail taken substantially along the line 4--4 in FIG. 2;
- FIG. 5 is similar to FIG. 4 but shows the end closure after it has been lifted from the container body.
- FIG. 1 shows a container body having a tubular body side wall 12 which is formed of sheet metal such as tin plate or aluminum.
- the body side wall 12 may have a side seam or it may be seamless. While the body side wall 12 is shown as being cylindrical, it may be of any cross-sectional configuration. It may also be formed of any other non-compressible material.
- the lower end of the body side wall 12 may be closed by an imperforate metal bottom end closure 14 which is secured to the side wall 12 in a conventional double seam 16.
- the lower end of the body side wall will be closed by a bottom end wall which is integrally formed with the body side wall.
- the upper open end of the body side wall- 12 is defined by a longitudinal end section 17 which is doubled-back onto the side wall 12 and partially engaged therewith.
- An inner marginal portion of the doubledback end section 17 is in the form of a projection or and engaged with, and conformed to the shape of, an annular exterior surface portion 25 of the body side wall 12.
- the lower extension 26 has a sharp raw metal edge 27 on its periphery.
- the doubled-back longitu dinal end section 17 of the body side wall 12 is thereby adapted to be incorporated, along with a thin plastic strip 20 into an end seam, generally designated 22, in a manner to be described hereinafter in greater detail, which secures an imperforate metal top end closure 24 to the container body side wall 12.
- the thin plastic strip 20 which for the purpose of this specification is sometimes referred to as a seam release strip, is secured to an annular, exterior surface portion 29 of the body side wall 12 displaced remote from the open end of the container body 10 by a layer of adhesive 28 (see FIG. 3) at the lower longitudinal edge portion 30 of the strip 20.
- the adhesive 28 may be of any suitable type, such as a pressure-sensitive adhesive or a thermoplastic adhesive, and should have a low-peel-resistance characteristic relative to the surface of the body side wall 12 to which it adheres. As shown in FIG. 3, the upper edge 32 of the seam release strip 20 abuts the lower edge 34 of the bead 18.
- the length of the strip 20 is shown as slightly greater than the circumference (periphery, in the case of a non-cylindrical body) of the body side wall 12 so that the strip 20 not only extends around the body in adhesive attachment thereto, but also overlaps itself a short distance to provide a grasping tab 36.
- the upper edge 38 of the tab 36 is cut down from the remainder of the upper edge 32 of the strip 20 to insure against this edge 38 being enclosed within the end seam 22 in a manner more fully described hereinafter.
- the ends 40, 42 of the strip 20 which are enclosed in the seam 22 are in substantially abutting relationship even though the tab 36 does overlap the opposite end 42 of the strip 20. While the overlapping tab construction is preferred, it is not absolutely necessary.
- the length of the strip 20 may be equal to or slightly less than the circumference of the body side wall 12 whereby the end 44 of the tab 36 may meet or just fall short of the oppositeend 42 (FIG. 2) of the strip 20.
- the purpose of the tab36 is to permit initial grasping and pulling of the strip 20.
- the tab 36 may be free of any adhesive attachment to the subjacent surface, but preferably it is weakly adhered to the subjacent surface.
- This weak adherence the tab 36 is held in substantial conformity to the contour of the body side wall 12, i.e., it is prevented from extending outwardly from the body side wall 12, thereby minimizing damage to the tab 36 or container body 10 during shipment or handling.
- This weak adherence is accomplished by continuing the bond of adhesive 28 onto the free end of the tab 36 to adhere the lower inside surface 46 of the tab 36 to the subjacent side wall surface 48. Pulling the tab 36 outwardly subjects this adhesive bond 28 to peel stress under which it ruptures readily.
- the end closure 24 comprises a central panel 50 merging at its periphery with an upstanding countersink wall 52, thence generally but substantially horizontally outwardly over the upper periphery of the bead l8 and thence generally downwardly in a hemmed skirt 54 to provide a substantially U-shaped channel 56.
- a sealing compound 58 is introduced into the U-shaped channel before attachment of the end closure 24 to the body side wall 12.
- the skirt 54 has a radially, inwardlyindented portion 60 which compresses the portion 61 of the strip 20, adjacent to the upper edge 32 of the strip whereat the strip 20 abuts the lower edge 34 of the bead 18, to lock the end closure 24 to the body side wall 12 in the endseam 22.
- the seam release strip 20 is adapted to have some degree of resiliency or compressibility to enable the skirt 54 to bite into and obtain a grip on the contiguous material.
- the indentation 60 also enhances the rigidity of the skirt 54, while further providing a smooth gripping surface which, along with a similar smooth gripping surface on the hem 62 of the skirt 54 insures a good gripping action without cutting into the material of the strip 20.
- the strip 28 is thinned out in the area where pressure is applied by the indentation 60 and hem 62.
- the inwardly-curled hem 62 on theskirt 54 compresses the annular portion 63 of the strip 20, which engages the sharp raw metal edge 27 of the lower extension 26, to cause further frictional engagement of strip portion 63 with the sharp raw metal edge 27, or, in effeet, to cause the sharp edge 27 to bite the strip portion 63.
- This engagement further enhances the locking of the end closure 24 to the body side wall 12 in the end seam 22.
- the strip 20 is made of a tough, flexible, tear-resistant thermoplastic resinous material, such as high, medium, or low density polyethylene, polypropylene, or copolymers of ethylene with monomers such as vinyl acetate or ethylacrylate, and may vary in thickness, de-
- the strip 20 should also have a tear resistance sufficiently high so that it does not tear during the opening operation. Its surfaces should preferably be smooth and have a relatively low coefficient of friction. It will be understood that the strip 20 may be formed of a single type of plastic or may comprise a lamination of one or more materials which can be selected to tailor the strip to specific container applications.
- the bead 18 is first formed on the body side ,wall 12.
- the strip 20 with the bond of adhesive 28 on a f lower longitudinal section thereof is then secured to the body side wall 12, adjacent to bead 18 in the position shown in FIG. 3. It is also possible to apply the'adhesive 28 to the body side wall 12 rather than to the strip 28.
- the end closure 24 with the sealing compound 58 in its inverted U-shaped channel 56 is attached to the body side wall 12 and the strip 20 by means of the end seam 22, the latter being formed, for example, by seaming rolls (not shown) in cooperation with a seaming chuck (not shown).
- the container may then be filled through the bottom end which is remote from the end closure 24, afterwhich the bottom end closure 14 is secured to this lower end by conventional means to completely close the package.
- the bottom end ⁇ closure 14 remote from the seam release strip 20 is .secured on the body side wall 12 before the container 10 is filled, but the seam release strip 20 may be placed on the body side wall 12 before or after the filling operation.
- the open end is fitted with the end closure 24 which is joined to the body side wall 12 by the seam 22 which encloses the seam release strip 20.
- the tab 36 is grasped and pulled outwardly, as indicated in FIG. 2, around the can to peel the interface of the strip 20 and the body side wall 12 and simultaneously disengage the upper edge 32 and adjacent portion from the end seam 22. This action is continued until the portion of the strip 20 within the end seam 22 is completely withdrawn therefrom, thereby loosening the attachment of the top end closure 24 to the body side wall 12.
- the top end closure 24 can then be easily lifted, also manually, off the body side wall 12 thereby providing a full opening of the container 10 for removal of the product therein.
- the removal of the strip 20 is facilitated by the fact that the adhesive 28 has low-peel characteristics which cause it to offer little resistance to the stripping action, which in the main is a peeling action.
- the adhesive 28 be selected so that it strips cleanly away from the outer surface of the body side wall 12 without tearing out or mutilating any portion of this surface, which may be a label surface which should remain intact after the opening operation to insure a clean, attractive appearance in the opened container.
- the exterior surface of the body side wall 12 may be coated with a suitable varnish or lacquer which is selected to provide the desired degree of adhesion between the adhesive 28 and the body side wall 12. If desired, the adhesive 28 may be omitted from all or a portion of the tab 36 to facilitate its engagement by the fingers.
- the pull tab 36 When the pull tab 36 is grasped and pulled in the manner just described, pressure is applied to cause the material of the plastic strip 20 adjacent its thinned portion (i.e., opposite the indentation and hem 62) to be pulled downwardly. Downward movement of the strip 20 is resisted by the portions of the strip 20 within the seam 22 which are of greater thickness than are its thinned portions.
- the plastic material from which the strip 20 is formed is extensible or elongatable, and thus the pulling pressure has the effect of causing the strip 20 to elongate and to thin down to substantially the thickness of the available gap so that it passes downwardly between the hem 62 and the body side wall 12 and thereby is removed from the end seam 22. Removal of the strip 20 from the seam 22 is facilitated by the fact that the surfaces of the indentation 60 and hem 62 which contact the strip 20 are rounded and smooth and that the raw edge 64 of the hem 62 is spaced away from the strip-20.
- the stretching or thinning out of the strip usually results in its being distorted into a thin, wavy configuration (see FIG. 2) which is indicative of a permanent distortion of the material of the strip 20.
- the degree of distortion will, of course, vary with the material from which the strip 20 is made.
- a full-opening container is advantageous for all products, but especially for products containing all or some solid substances since no end closure is left on the body to act as an obstruction to the removal of the solids, and the fit between the closure and the body, after opening, permits ready reclosure during the useful life of the container.
- the invention is useful for all products and particularly pressurized products, including food products temporarily pressurized during processing as is common in food canning, because the projection or bead l8 insures seam integrity, particularly under such pressurized conditions, in that it serves as an abutment or stop to prevent the plastic seam release strip 20 from sliding up on the container body side wall 12.
- the bead 18 also facilitates proper alignment of the seam release strip 20 as the latter is applied to the container body side wall 12 and also functions to maintain the proper position of the strip 20 during assembly of the end seam 22.
- the construction of the bead 18 is such that the raw edge 27 on the lower extension 26 is carried externally of the container 10 out of any contact with the container contents and further, that the bead l8 eliminates exposure of sharp edges and protects the consumer, particularly enhancing reclosure conditions.
- a plastic strip the separate annular portions of which being respectively releasably adhered to another annular exterior surface portion of said side wall, engaged with still another annular exterior surface portion of said side wall with said still another portion being between, and merging with, the other annular exterior surface portions of said side wall, engaged with the exterior surface of said outer marginal portion of said doubled-back end section, and abutted with said inner marginal portion of said doubled-back end section, to thereby securely maintain said plastic strip annularly about, and in a predetermined position displaced longitudinally from, the open end of said container body.
- an end closure having a container end defining portion which merges into an annular peripheral skirt, said skirt extending longitudinally from the open end of the container body and having a radially inwardly indented portion which compresses the one of said separate annular portions of said plastic strip that abuts said inner marginal portion of said doubled-back end section to thereby facilitate sealing of said open end of said container body by said end closure.
- said skirt of said end closure further has a peripheral, radially, inwardly-directed curled hem which compresses the one of said separate annular portions of said plastic strip that engages said still another annular exterior surface portion of said side wall to frictionally engage said one of said separate annular portions of said plastic strip with said sharp raw metal edge on said outer marginal portion of said doubled-back end section of said side wall, and to thereby further facilitate sealing of said open end of said container body by said end closure.
- a sealing compound disposed between the annular interior surface portion of said side wall adjacent the open end of said container body and the marginal peripheral portion of said container end defining portion of said end closure to thereby further facilitate sealing of said open end of said container body by said end closure.
