Definitions

  • This invention relates to a container having a portion of its wall weakened to serve as a tear strip and having a tab attached to the tear strip to serve as a lever for initiating the severing operation.
  • the invention is directed to two problems which have come to the fore with widespread acceptance of this type of container.
  • One problem is to make it easier to manipulate the tab for leverage action to initiate the severance of the tear strip.
  • the second problem arises in the use of a container for carbonated beverages and is the hazardous effect of the internal fluid pressure on the tear strip.
  • the internal fluid pressure is directed against the underside of the tab while the tab is at a low angle and consequently the pressure against the tab may abruptly complete the severance of the whole tear strip and propel the separated tab away from the container at a dangerously high velocity.
  • the present invention solves both of these two problems by so constructing and mounting the tab that the actual work performed by the lever action, i.e. the actual severance of the tear strip, is delayed until the tab swings away from the container Wall to an angle great enough for the operator to insert his thumb under the tab sufficiently to grip the tab effectively.
  • the actual work performed by the lever action i.e. the actual severance of the tear strip
  • the tab swings away from the container Wall to an angle great enough for the operator to insert his thumb under the tab sufficiently to grip the tab effectively.
  • thumb pressure applied directly to the underside of the tab is wholly a lifting force.
  • the invention teaches further facilitating access to the underside of the tab by bending the handle end of the tab slightly outward and by forming an indentation in the container wall adjacent the handle end of the tab. With these further features it is easy to lift the tab to the starting angle and especially so because initially no work load is imposed on the lever. With further reference to the second problem, the invention further teaches the deformation of the leading end of the tear strip by the lever action in such manner that the initially severed metal is positioned to serve as a baffle for directing the high velocity gaseous fluid away from the tilted path.
  • the invention solves this problem by a novel tab construction which results inherently in delayed resistance to lifting of the tab.
  • the whole tab is rigid including the portion of the tab that is connected to the tear strip.
  • the tab is apertured for engagement by a hollow rivet that is formed in the tear strip and the hollow rivet, in effect, becomes a rigid part of the tab.
  • a minor end portion of the tab is connected to the hollow rivet of the tear strip and the remaining major portion of the tab functions as a second-class lever adapted for cam action against the can top.
  • the tab is in effect hingedly connected to the rivet because the tab is flexible to yield and bend freely at the juncture of the two portions of the tab, and the yielding and bending action occurs during an initial portion of the upward swing of the lever before the upward swing encounters the resistance of the actual severance of the tear strip.
  • the fulcrum end of the second-class lever is made relatively short and is of forked configuration to straddle the rivet.
  • hingedly connecting the second-class lever to the leading end of the tab together with shortening the fulcrum end of the second-class lever results in initially lifting the leading end of the tear strip to only a slight angle thereby to cause the leading end of the tear strip to serve as a baffle for deflecting the high velocity gases away from the upturned tab.
  • the second-class lever may be spaced appreciably outward from the can top but such spacing is not necessary for obtaining the delayed action.
  • the aperture of the tab that receives the hollow rivet is formed with a flange or hub portion which may either be turned inward towards the can top or may be turned outward away from the can top.
  • This flange or hub portion which serves as -a collar that tightly embraces the rivet also strengthens the connection between the lever and the rivet and additionally gives high rigidity to the rivet and the adjacent portions of the tab and tear strip that surround the rivet.
  • another provision is to round to a radius the forked fulcrum end of the lever that acts against the can top.
  • the rounding of the fulcrum end delays the contact of the fulcrum end with the can top and provides a cam action to lift the rivet for initiating the severance of the tear strip.
  • a certain safety feature is provided in that if the lever is swung through the maximum angle of approxi- 3 mately 180 only the leading end of the tear strip is severed and thus there is no tendency for the follow through of the leverage operation to remove the whole tear strip.
  • a further safety feature is the narrowing of the tear strip adjacent its leading end to reduce the magnitude of the force on the tear strip exerted by the internal fluid pressure immediately after the lever action, the force being reduced to such degree that there is no significant tendency for the fluid pressure alone to complete the tearing operation.
  • FIG. 1 is a fragmentary plan view of a metal can top incorporating the presently preferred embodiment of the invention
  • FIG. 1a is a cross section of the tab taken along line 1a1a of FIG. 1
  • FIG. 2 is a greatly enlarged fragment of FIG.1;
  • FIG. 3 is a sectional view showing the lever ,at its normal position prior to the operation of opening the can;
  • FIG. 4 is a similar view' showing the lever lifted through an initial range of movement to a relatively high angle before the lever exerts severing force;
  • FIG. 5 is a similar view indicating how upward swing of the lever through a second short range of movement results in straining the structure without actual severing the metal;
  • FIG. 6 shows how the lever enters into a third range of its swinging movement to sever the leading end of the tear strip and to deform the leading end to a configuration for deflecting the escaping gases away from the tilted tab
  • the hub rigidly connects the tab to the rivet and strengthens the portion of the tab that surrounds the rivet.
  • the sheet metal of the lever 22 is suitably offset for longitudinal stiffness.
  • the two longitudinal sides and the handle end of the lever are stiffened by a peripheral flange which is shown in section in FIG. 1a and which is rolled under to form a bead 28.
  • the lever 22 is offset to form a shoulder which is U-shaped in plan with the opposite ends of the shoulder extending along the two fulcrum ends 27 of the lever adjacent the two slots 24.
  • FIG. 7 is a fragmentary sectional view showing how the can top may be indented under a fulcrumend to reduce resistance to initial lifting of the tab.
  • a sheet metal can top which may be made of a suitable material such as aluminum or steel, is of the usual peripherally flanged configuration as required for joining the can top to a cylindri-' cal can body.
  • the can top 10 is scored along a continuous line 12 to form an elongated tear strip 14 and a suitable sheet metal tab, generally designated 15, is attached to the leading end of the tear strip to function as a second-class lever for initiating severance of the tear strip from the can top.
  • the tear strip 14 is enlarged in area at its trailing end and short ribs 16 are embossed in the can top adjacent the opposite sides of the tear strip to stiffen the can top and thus facilitate the final severance of the tear strip. It is to be noted that the tear strip 14 is reduced in width in the region 17 adjacent its leading end.
  • the tab 15 may be connected to the tear strip 14 in any suitable manner.
  • the leading end of the tear strip is formed with a hollow rivet 18 of circular configuration which extends through a corresponding aperture of the tab in overlapping engagement with the rim of the aperture.
  • a minor forward end portion 20 of the tab is engaged by thehollow rivet 18 and is of circular configuration to conform to the circular configuration of the rivet.
  • the remaining major portion 22 of the tab functions as a second-class lever for initiating the severance of the tear strip.
  • the aperture in the minor end portion of the tab that is engaged by the rivet is formed with an inwardly extending cylindrical circumferential flange or hub 23, as shown in FIG. 3 that tightly embraces the rivet.
  • the hub 23 materially strengthens the hollow rivet and in addition spaces the lever 22 outward from the can top, but as heretofore stated such ably the bottom of the trough is stiffened by a short embossed rib 33 spaced from the bend line 26.
  • the shoulder 30 forms a step from the bottom of the trough 32 to a relatively wide U-shaped' marginal portion 34 of the lever that extends along the two longitudinal sides of the lever and around the arcuate end of the lever.
  • the hub 23 of the end portion 20 of the tab spaces the bottom of the trough 32 of the lever 22 outward from the can top 10 and the major area of the ,tab represented by the U-shaped margin 34 is additionally spaced outward from the can top for improved access to the underside of the lever.
  • the under face of the lever 22 is roughened for more effective gripping of the lever by the fingers of the user.
  • the metal of the lever may be offset at distributed points to form bosses or hob nails 37 shown in FIG. 3.
  • the lever 22 Since the length of the pair of fulcrum ends 27 of the lever 22 as measured from the bend line 26 is relatively short and since there is an appreciable amount of lost motion in the bending and yielding of the pliable web of the lever in the region of the bend line, the lever may be swung upward to a substantial angle'before the two fulcrum ends start to work on themetal of the can top with cam action on opposite sides of the tear strip to initiate the severance of the tear strip.
  • a further feature of the invention is that the rounding of the two fulcrum ends 27 of the lever as indicated at 38 in FIGS. 3 and 4 to provide the cam action also increases this angle and smooths the action of the lever.
  • the manner in which the invention serves its purpose may be understood from the foregoing description.
  • the only resistance to the lifting of the lever 22 through an initial range to the relatively large angle shown in FIG. 4 is the relatively slight resistance to yielding and bending of the pliable web of the tab along the transverse bend line 26.
  • Merely engaging the handle end of the lever 22 by the tip of a finger or even by a fingernail is sufficient to lift the tab and the required initial finger engagement with the end of the tab is facilitated by the C-shaped recess 35 in the can top and by the fact that the free end of the lever is bent outwardly in addition to being appreciably spaced from the can top.
  • the two fulcrum ends 27 of the lever exert pressure on the can top on opposite sides of the rivet 18 by cam action with progressively increased stressing of the parts involved without actually initiating severance of the tear strip.
  • This second range starts at the position of the lever shown in FIG. 4 and terminates at a higher angle which may be approximately the angle shown in FIG. 5 where the leading end of the tear strip is ready to rupture.
  • the applied energy results in slight indenting of the metal of the contact of the can top by the short fulcrum ends 27 of the lever and results in deformation of the leading end of the tear strip with slight tilting upward of the hollow rivet 18 as indicated in FIG. 5.
  • the upward tilting of the hollow rivet results in concentrated stress on the tear strip near the score line 12 in the region indicated 44 in FIG. 5, this region being under the previously mentioned bend line 26 about which the lever pivots.
  • the stress developed by the lever is of high magnitude both because of the cam action and because the length of the two fulcrum ends of the lever is several times the length of the handle portion of the lever as measured from the bend line 26.
  • the progressively increasing stressing of the metal in the region 44 reaches a maximum at approximately the angle shown in FIG. 5 and then the metal yields and ruptures with a snap action.
  • the metal is thinned by coining as shown in the region 44 to favor the tearing action and to increase the axial dimension of the hollow rivet.
  • the snap action from the position of the lever shown in FIG. 5 to the position of the lever shown in FIG. 6 is the third range of swinging movement of the lever.
  • FIG. 5 shows how the rivet 18 is tilted by the snap action as the metal is initially torn and it is important to note that the rivet 18 which is the leading end of the tear strip is inclined outward at only a small angle in FIG. 6.
  • the lever 22 is bent outward to a high angle to favor avoiding impact by the escaping gaseous fluid and that the tilted rivet or leading end of the tear strip serves as a batfie to deflect the escaping gaseous fluid away from the lever.
  • the hollow rivet 18 and the associated leading end portion of the tab constitute a rigid tiltable structure and the hub 23 is important in contributing to the required rigidity.
  • the new arrangement provides a high leverage advantage as well as the force-multiplying advantage of a cam it is easy to understand the freedom with which the lifting of the tab can be initiated.
  • a further factor is in the yielding action of the tab in the region of the connection of the lever with the rivet.
  • FIG. 7 shows how an indentation 46 may be made in the wall of the can below each fulcrum end 27 of the lever to delay the pressure contact of the lever with the can top and thereby reduce further initial resistance to raising of the tab.
