Definitions

  • the present invention relates to a closure and particularly relates to a type of closure to be ap-
  • a type of closure to be ap-
  • a relatively soft metal cup is employed, the skirt of which is tucked inwardly 10 about the bottle or container mouth, a cork disk usually being inserted in thebase of the cup and contacting said lip.
  • the gathered metal edge which is an inherent characteristic of this type of cap is usually ll crimped about the upper bead at the top of the bottle by laterally moving jaws, which jaws are positioned so as to compress the skirt into the recess below said upper head.
  • the metal edge when so gathered in the ordinary Crown type of cap bulges outwardly giving an unsightly appearance at the 30 top of the bottle and also forms an outstanding sharp edge, often causing injury.
  • bottle tops in which the outside diameter of the head will be fairly uniform, although the as depth of the bead may vary and it is among the objects of the present invention to provide an improved bottle'cap for such bottles, in which the bottle cap may be secured onto the bottle in a firm and secure manner without the necessity 40 of using lateral clamping jaws, and which, at the same time, may also be attached without the usual unsightly appearance and the customary sharp edge.
  • a cap is formed of a sheet of metal with a circular base and a skirt having an out-turned corrugated portion with an intermediate ridge.
  • the ridge and corrugated portion are adapted to be inwardly pressed by a downwardly moving capping die which will straighten out the ridge and in so doing, press the corrugated portion into the groove below the bead.
  • Figure 1 is a side elevational view.
  • Figure 2 is a cross sectional view upon the line 2-2 of Figure 3.
  • Figure 3 is a bottom view upon the line 3-3 of Figure 2.
  • Figure 4 is a cross sectional view of the cap of Figure 1 on the top of the bottle and about to be pressed into sealing position upon the top of the bottle by a capping die.
  • Figure 5 is a side elevational view of the cap after attachment to the bottle.
  • Figure 6 is a cross sectional viewof the cap of Figure 5 when attached, on slightly enlarged scale.
  • the cap has a base ID, with an upper skirt ll, an intermediate ridge l2, and a lower skirt l3.
  • the upper skirt portion ll receives the cork disk or insert ll.
  • the ridge l2 extends outwardly beyond the upper skirt portion ii to provide extra metal.
  • the skirt portion l3 consists of a series of indented portions H, and outwardly extending rounded portions l5.
  • the cap may be made most conveniently of alloys of tin, brass, copper, aluminum and/or lead.
  • acylindrical die I9 with a bevelled lower edge 20 may be employed.
  • the die id contains an actuating member 2! screwed at 22 into the threaded recess 23.
  • the 5 cylindrical member I9 also receives the coil spring 24 which presses down the fiat die member 25.
  • the flat member 25 has an upstanding nipple 26, which is tapped and receives the bolt 27 having the head 28.
  • the bolt passes through the open- 10 ing 29 in the cup 23 and may reciprocate in said cup 23 and also in the recess 36 in the end of the rod 2
  • the capping die l9 will come down and the bevel 26 will strike the extended edge l2 collapsing the metal of the lower portion 13 thereof from the position A to the position B until the cylinder reaches the lower dotted line position, as indicated in Figure 4.
  • the fiat element 25 will press down upon the base iii and the cork il holding them in position upon the top of the bead ii.
  • the caps may ordinarily have a maximum external diameter of the ridge E2 of 1 inches, and a maximum depth 40 before placement upon the bottle top of inch.
  • cork disk 341 of the cap of the present invention need not be glued into position as is necessary with the usual type of Crown caps since the indentations I 6, as best shown in Figure 3, extend inwardly adequately to prevent the disk from falling out'of position.
  • steel alloy may also be utilized as a material for making the cap of the present invention.
  • the usual Crown blank consists of a disc 1 inches in diameter, whereas the blank for the cap of the present invention may be con- 5 veniently 1 inches in diameter.
  • the cap of the present invention is particularly advantageous inasmuch as it may be more readily removed from the tops of bottles without deformation and may be constructed with a con- 'siderable saving of metal over and above the usual Crown type of seal.
  • a cup shaped cap for application to bottles provided with top beads and similar containers, said cap having a circular base, a skirt depending circularly from said base, a cylindrical pliable sealing disk inset against said base inside of said skirt, said skirt having a corrugated or indented lower portion, a smooth cylindrical upper portion and an intermediate portion providing extra metal, said intermediate portion taking the form of an outwardly projecting fold, said fold being adapted to be unfolded and spread to extend said skirt to grip the side of the bead and force the corrugated portion tightly below the bead.
  • a cup shaped cap forv application to bottles provided with top beads and similar containers said cap having a circular base, a skirt depending circularly from said base, a cylindrical pliable interior of the cap between the fold and the base.
  • a cup shaped cap for application to bottles provided with top bead and similar containers, said cap having a circular base, a skirt depending circularly from said base, a cylindrical pliable sealing disk inset against said base inside of said skirt, said skirt having a corrugated or indented lower portion, a smooth cylindrical upper portion and an intermediate portion providing extra metal, said intermediate portion taking the form of an outwardly projecting fold, said fold being adapted to be unfolded and spread to extend said skirt to grip the side of the bead and force the corrugated portion tightly below the bead, said corrugated lower portion having inwardly extending parts projecting inside of the periphery of said disk, whereby said disk is held in position.
  • a cup-shaped cap for application to containers provided with top beads, said cap having a circular base, a skirt extending circularly from the periphery of said base, and a pliable sealing disk inset against said base inside of said skirt, said skirt being provided intermediate of its length with an outwardly projecting bulged portion adapted to be spread to extend the skirt in the direction of the axis of the cap and said skirt having corrugations or indentations between said bulged portion and the edge of said skirt which are adapted to collapse circumferentially during the extension of said bulged portion, to grip tightly below the head, but which are retained generally in an axial direction, to facilitate engagement of an uncapping element therewith, by the union circumferentially of contiguous corrugations or indentations.
