Definitions

  • caps in accordance with the invention and those formed by the method of the invention may also be effectively employed for the closing and sealing of the openings of bottles of all sorts, jars of which baby food jars are a non-limiting illustration, cans when the same have openings with bottle-like finishes and any other containers similarly finished.
  • hand removable refers to the means providing by the cap which may be grasped by the fingers of anyone, even a child, and actuated to destroy the cap and thus achieve its removal from the opening without the use of any kind of tool.
  • commencement of the tearing has been provided for with such case that even a light unintentional striking of the tearing ear has caused the seal to be broken and the pressure on the contents to be lost.
  • the scoring has also affected the tear strip particularly where it extends down the skirt of the cap in such a manner that removal must be achieved by pulling in definite directions during different parts of the action lest the ear or the tear strip tears off before the bottle opening is reached and consequently before it is opened. This has made it necessary to apply a legend to the top of the cap and tell exactly how to pull on the ear to remove it. However a suflicient portion of the users either do not read the legend or do not understand or follow what they have read so that an annoying large number of such caps have had their ears or tear strip torn oft before the bottles have been opened.
  • the cap of the invention and method of forming the same are in the category of the lightweight metal caps with tear strips ending in tearing ears but in the method of forming them and in the structure resulting therefrom proper provision has been made to overcome the deficiencies of the prior art cap just described.
  • the cap of the invention when properly applied to a bottle or other suitable container first assures the provision of a tight seal against pressure even greater than that previously contained by the prior art caps. No instructions or directions are needed to enable the consumer to readily remove the cap. He merely needs to grasp the tearing ear and pull out or up as suits him to enable him to start and continue the tear of the strip along the score lines up the skirt and across the top to sufiicient extent to cause the top to pop off.
  • One feature by which the invention construction eliminates the prior art drawbacks is the novel and precise manner in which the scoring is imparted to the cap.
  • the blank for the cap is made and the scoring is specially formed in it so that as the blank is cupped to form the cap the metal when moved into its changed position carries the scores'with it so that they end up aligned with the sides of the tearing ear in its extension away from the cap skirt. This is achieved when scoring the flat blank by particular outward flaring of the scores with respect to the sides of the ear in their extension toward the periphery of the blank.
  • the blank is also not'ched inward from its periphery at either side of the extending ear portion to provide a place for the metal of the blank portion forming the cap skirt to flow as its diameter is decreased from that in the flat blank to that of tthe cylindri- -cal skirt.
  • the scores in the cap blank extend to a position closely adjacent the base of the notches leaving a small section of material therebetween which, while the blank is in the flat, is neither notched nor scored.
  • the border of the flat blank is moved laterally to form the cap skirt the .notches are closed up as are the scores.
  • the scores are closed in progressively starting from the position where the skirt of the cap departs from the top downwardly to their terminating ends where they are substantially completely closed.
  • the small sections of metal remaining unscored between the notches and the ends of the formed scores are creased or pinched in a line which is an extension of the score to what, in each case, was the border of the notch. This creasing results from a puckering of the metal extending between the score and the notch which can be closed up as the skirt is formed while the small unscored portions between them has no such provision for reduction of its width.
  • Another object is to provide a novel method for manufacturing such caps.
  • Another object is to provide such closure caps, which though readily destructible and removable when intended, are stronger and more pressure-resistant than comparable closure caps heretofore employed.
  • Still another object is to provide such closure caps which though scored for destructibility and ease of removal withstand the action of securing them to container openings with a minimum of weakening.
  • Still another object is to provide such closure caps which, although capable of effectively sealing containers against internal pressures well in excess of accepted standards, are readily and easily hand removable.
  • a further object is to provide flat scored blanks for the formation of hand removable closure caps which blanks are so formed to retain their weakening strength where needed to resist in the drawing of the cap skirt portion away from the cap top portion.
  • a still further object is to provide hand removable closure caps which, though including a gripping ear to facilitate the intentional removal thereof are free from failure due to moderate accidental movement of such ear.
  • a more detailed object is to provide a method for forming scored closure caps having a top and a skirt extending therearound wherein the inherent deformation of the score portions in the skirt caused by the drawing of said skirt from a flattened to a laterally extending position with respect to that flat, enhances scalability while facilitating removability of such caps.
  • FIG. 1 is a plan view of the cap blank for use in forming the closure cap of the invention.
  • FIG. 2 is a vertical section including the blank of FIG. 1, taken on line 22 thereof, of die elements for performing the scoring operation in the method of cap forming in accordance with the invention with those die elements in their initial position and with the blank therebetween ready for the commencement of the scoring.
  • FIG. 3 is a plan view of the cap blank of FIG. 1 after the scoring operation has been completed.
  • FIG. 4 is a greatly enlarged fragmentary plan showing of the portion of the scored blank of FIG. 3 adjacent the commencement of the tearing ear.
  • FIG. 5 is an enlarged vertical sectional view of the cap blank taken on line 55 of FIG. 3 and looking in the direction of the arrows.
  • FIG. 6 is a vertical sectional view of die elements for performing the drawing operation in the method of cap forming in accordance with the invention showing those die elements in their final forming position with a cap therebetween.
  • FIG. 7 is a greatly enlarged fragmentary section of the score portion in the cap skirt as viewed interiorly of the finished cap.
  • FIG. 8 is a view similar to FIG. 7 showing the prior art scoring.
  • FIG. 9 is a perspective view of a completed cap in accordance with the invention with a fragment of the nonscored portion of the skirt broken away to expose the interior thereof and,
  • FIG. 10 is a part elevated part sectional view of a cap applied to a container neck.
  • the cap generally indicated at 1 comprises a flat disc-like top 2 surrounded by a depending skirt 3 with the numeral 4 indicating the juncture of the top and skirt.
  • the skirt 3 terminates in a downwardly facing free edge 5, which edge forms a continuous circle except for the portion 6 which extends downwardly from the bottom of the skirt 3 for a short distance forming the juncture of the skirt with a radially outward extending, integrally formed ear 7.
  • the ear 7 is provided with two substantially parallel sides 8 and 9 and an end 10.
  • the interior surface of the cap 1 is provided with a pair of scores with portions 11 and 12 which extend across the cap top 2, portions 13 and 14 extending across the juncture 4 of the top and skirt and portions 15 and 16 which then continue for a distance down the skirt 3 in substantially parallel relationship.
  • the top score portions 11 and 12 are formed with an outwardly divergent sweep which aids in removing cap from the bottle or other container opening to which it is applied.
  • the configuration of the top score portions 11 and 12 may be varied somewhat without departing from the scope of the invention, it is important that the score portions 15 and 16 in the skirt 3 be in substantially parallel relationship with each line respectively positioned in alignment with the sides 8 and 9 of the ear 7.
  • the formed cap is provided with slits 17 and 18 extending upwardly from the free edge 5 up into the skirt 3 where the sides 8 and 9 of the ear depart from the skirt edge. These slits extend completely through the wall of the skirt forming very narrow severances or breaks in the lower portion of the skirt. These slits 17 and 18 extend in alignment with the score portions and 16 but stop short of the ends of those score portions. There accordingly remain zones of metal which is neither scored nor slitted between the lower ends of the scores 15 and 16 and the upper ends of the slits 17 and 18.
  • a gasket 19 is secured therewithin.
  • the gasket 19 is preferably formed in situ and results from the applying of material in fluid form interiorly of the top and skirt juncture 4. Such material when suitably heat cured, sets up into the form of a resilient gasket permeanently adhered to its seat within the cap. As shown, the gasket 19 extends part way inwardly beneath the top 2 of the cap at 20 and part way down the skirt 3 of the same to the portion 21.
  • gasket 19 and its method of application could be varied without departing from the invention.
  • the gasket could be formed as a linear completely covering the interior of the cap top.
  • such gasket could be spun in or hot stamped and either heat cured or air dried. In either of these gasketting arrangements, the form of the cap and its sealing principle remain the same.
  • cap blank a flat blank generally indicated at 23.
  • the size and thickness of the cap blank may vary over a wide range depending upon the final size of cap desired.
  • One cap in accordance with the invention which has been found to be particularly suited for the capping of bottles containing beer, carbonated beverages and the like is formed from lightweight sheet aluminum approximately .010 inch in thickness.
  • the zone where the juncture of the top and skirt of the finished cap will be located is indicated on the fiat blank of FIGS. 1, 3, and 4 by the dot dash line 4.
  • the portion of the fiat blank representing the skirt portion of the finished cap is indicated at 3 and the cap top is at 2 on the blanks of FIGS. 1, 3 and 4.
  • the cap ear 7 is also shown in the flat blank along with its side portions 8 and 9 and end portion 10. It is important to note, however, that the flat blank, in stead of having the narrow-slits 17 and 18 as shown in the finished cap of FIG. 9, is formed with a pair of open notches 24 and 25 located on either side of the ear 7. In the greatly enlarged showing of FIG.
  • the notches 24 and 25 extend in from the periphery of the blank in a U-shape whose inner sides 26 and 27 form continuations of the ear sides 8 and 9. Their outer sides 28 and 29 meet theblank periphery, which forms the skirt edge 5, at the points 30 and 31 respectively while the concavely curved bottom portions 32 and 33 complete the U-shaped.
  • FIG. 2 wherein the cap blank 23 of FIG. 2 is shown in scoring position between an upper scoring die member 34 and a lower scoring die member 35.
  • the lower scoring die member is provided with a pair of scoring knives 36 and 37 which, upon closing of the die, embed themselves to a predetermined depth into the material of the blank from the lower surface thereof. Due to the thinness of the metal 6 and the pressure which the finished cap has to withstand this scoring must be accurately controlled to leave enough metal beneath the bottoms of the resultant grooves to hold the pressure while making the score deep enoughto assure ease of tearing therealong.
  • FIGS. 3, 4, and 5 show the cap blank 23 after the scoring operation has been completed.
  • the score portions shown in finallocation in FIG. 9 are indicated on the flat blank of FIG. 3 by the same reference characters.
  • the score portions 11 and 12 extend across the central top portion 2, the portions 13 and 14 extend across the juncture 4, and the portions 15 and 16 partially cross the skirt portion 3. It is important to note however, that the score portions 15 and 16 in the skirt portion of the flat blank are not formed in parallelism but diverge outwardly terminating respectively at points 38 and 39.
  • the distance between the score portions 11 and 12 at the positions 40 and 41 where they leave the juncture zone 4 between the top and skirt and start across the flat top 2 is the same as the distance between the inner sides 26 and 27 of the notches 24 and 25. his also the same as the with of the ear 7 and at the positions 40 and 41 the score portions 11 and 12 are aligned with the sides 8 and 9 of that ear. As the score portions 11 and 12 cross the juncture zone 4 at 13 and 14 and continue outwardly across the skirt portion they curve away from each other to positions where their ends 38 and 39 lying just short of the central portion of the notch bases 32 and 33.
  • the distance between the ends 38 and 39 of the score portions is substantially greater than the distance between the notch inner side Walls 26 and 27, leaving areas of metal generally indicated at 42 and 43 respectively lying between the score portion 15 and 16 and lines forming projections of the sides 8 and 9 of the ear 7.
  • the scoring can be effected before the cap is blanked out of a metal sheet or strip. Then as a second step, blanking and drawing can be carried out in one operation.
  • the scoring and drawing are to the same effect for the purposes of the invention whether the scoring and drawing operations are performed on a cap blank as illustrated or the cap blank is first scored in the strip then blanked and drawn.
  • the drawing operation is performed with an upper die member generally indicated at 44 and a lower die member 45 which die members are shown in FIG. 6 in closed relationship about a formed cap 1.
  • the upper die member 44 has an inner element 46, which holds the cap top portion of the flat blank against the lower die member 45, and an outer element 47 which draws the skirt portion'of the blank laterally away from the top.
  • the skirt portion of the cap moves from its flattened position in the blank to the reduced circumference of the finished cap, there results a movement or slight upsetting of metal within the skirt wall causing a corresponding thickening'and elongation of the same.
  • the scoring is the weakest portion of the skirt, such deformation and any detrimental effects thereof are concentrated in the score area.
  • the showing in FIG. 8 illustrates what happens when a cap blank with the prior art scoring is cupped in this manner.
  • the first step is by imparting an outward flaring to the scores 15 and 16 while in the flat skirt area.
  • those score portions move towards each other.
  • the score portion 15 and 16 assume the relatively parallel relationship when the blank is cupped as shown in FIG. 6.
  • the contrast between the invention and the prior art is immediately apparaent from the side by side showings of FIGS. 7 and 8.
  • the movement of the peripheral portion of the skirt 3 from its flattened form to its laterally extending positions has caused the notches 24 and 25 to become completely closed.
  • the outer notch sides 28 and 29 have moved inwardly meeting the inner sides 26 and 27 respectively leaving only the slits 17 and 18 in the finished skirt.
  • This arrangement provides a controlled slit replacing the severe deformation and varied fracturing of the scored portion adjacent the edge of the skirt as characterized by the prior art.
  • the flared score portions 15 and 16 have also moved towards each other in the cupping of the blank.
  • the areas 42 and 43 have been completely absorbed in the intermediate skirt wall portion resulting in the scored portions 15 and 16 being brought into parallelism and into alignment with the sides 8 and 9 respectively of the ear 7.
  • What has been done here is to utilize the inherent movement of metal in the skirt 3 as it is drawn to a reduced circumference to convert outwardly flared lines into desired straight lines in contrast to'the prior art practice of deforming straight lines into an undesirable inwardly curved lines.
  • a substantially vertical line can be drawn from the point 46 ⁇ where the scoring starts across the cap top down through the bottom end 38 of the score portion 15.
  • That line also extends down through the slit 17 which was the notch 24. That line passes through the points 32 and 30 at the top and bottom of the slit and down along the side 8 of the car. With this arrangement, very little pulling effort applied to the gripping ear 7 causes the tear strip to be torn along the scores and enables the cap to be torn off from the container. It is here to be noted that the scores 15 and 16 do not extend to the lower edge 5 of the skirt, where the disturbance of the metal is most severe.
  • Another important feature of the invention resides in the retention of unscored sections of metal, indicated at 55 and 56 in FIG. 4 bridging the spaces between the ends 38 and 39 of the scored sections 15 and 16 and the notch bases 32 and 33.
  • the sections 55 and 56 are of such small extent in the line between the ends of the score portions at 38 and 39 and the bases of the grooves opposite the same at 32 and 33 that the metal in the unscored sections is necessarily deformed and weakened when the skirt of the cap is formed laterally from the peripheral portion of the flat blank. This lateral forming obviously diminishes the diameter of the skirt section to increasing extent as the periphery is approached.
  • the score portions 15 and 16 are progressively closed in a direction towards the unscored portions 55 and 56 while the notches 24 and 25 are closed all the way up to form slits.
  • the lines of weakening across the sections 55 and 56 connect the slits 17 and 18 with the score portions 15 and 16.
  • this small unscored portion performs several important functions. First, it has the strength to prevent the cracking open of the scores when the caps are applied over the beads or other finishes on bottle necks. Next, it serves as a safeguard against accidental opening of the score and consequent loosening of the cap and loss of pressure which occurs in prior art closures on unintentional movement of the ear. Finally, and contrary to what one would think, the lines of weakening enhance the proper removal of the cap since they act as guides for the tear between the slits and the scores. As one grasps the ear and pulls on it he quickly jumps through the weakened but unscored portions whereupon the tearing naturallly follows into the precisely formed aligned scores, rather than running out of and away from the scores as commonly happens in the prior art.
  • the specially formed score portions 15 and 16 being bordered at their sides by metal which is relatively unstressed, and by being in the natural direct tearing path following along the sides of the ear 7 provide almost a guarantee that the tearing will go straight up them. They provide the only weakened path and there is nothing like the inward incline of the scores and consequent disturbance of the metal of the tear strip, as in the prior art, to cause the tearing to run off at an angle.
  • a flat substantially circular blank adapted to be formed into a cap having a disc-like top portion, a laterally depending skirt depending from and around said top portion, a pair of spaced weakened tearing lines in said top and skirt and a tearing ear extendmg outwardly away from the lower edge of said skirt formed as an integral extension of that portion of said cap skirt lying between said weakened lines, said blank comprising an annular peripheral cap skirt portion, an inner circular cap top portion, a flat tearing ear extending radially outwardly from a peripheral edge portion of said blank, a pair of weakened lines extending at least part way across said top portion and continuing outwardly into said skirt portion, said weakened lines at the point of their departure from said cap top portion being in substantial alignment with the sides of said ear, said weakened lines flaring outwardly away from each other in their extentfrom said caps top portion to said peripheral edge and terminating in the region of said blank periphery with a space therebetween of greater width than said ear.
