Definitions

  • liquids bottled under pressure such-as aerated waters, ale, beer, beverages and the like, the
  • the present invention comprises providing the seals with means which can be positioned to give leverage and (if desired) a finger grip so that the rim or skirt of the seal without any pre-weakeningmeans can be broken or fractured to'an extent which will enable release of and complete removal of the seal.
  • FIG. 1 shows a sectional elevation of the seal
  • Fig. 3 is a plan view of Fig. 1,
  • Fig. 4 is a'sectional side elevation on line A-B of Fig.- 1. a r
  • Fig. 5 shows a perspective view of a seal as applied to a. bottle
  • Fig. 6 shows a seal broken by its removalfrom a bottle
  • the top 3 is partially pierced or severed at .l in certain parts only (see Fig. 3) so as to form all a a central disc or tongue which may be called a lifting disc or levering tongue 5 and due to being so pierced at l, the levering tongue I is integral with the seal, in that said piercing 4 terminates preferably at the circumference I of top 3.
  • a sealing disc i2 is provided between the top 3 and the usual cork or like washer it.
  • the seals When the seals are manufactured, they are substantially flat on the top 3 as shown in Figs. 1, 2, and 3, but when applied to a bottle, the seal applying machine slightly domes the top 3 and this causes the free end N of the levering tongue 5 to spring out or be raised a small distance clear of the top 3, thus giving a finger grip as shown in Fig. 5.
  • the seal removal could be a two handed operation by holding the bottle in one hand and pulling the levering tongue 5 upwardly with the other, but the method of removal previously described has been found best from the point of view of safety from getting scratched fingers, in that the thumb will be away from the side of the seal at which the tear or fracture takes place.
  • levering tongue 5 was perfectly fiat and did not have the strengthening means along its length (such as corrugations 1) said levering tongue 5 would bend in its length and thus necessitate a pulling action instead of a leverlng one in order to tear across or break the rim or skirt 2 and it has been found that by continuing the outer grooves 8 and 9 right through to the top circumference 6, these grooves 8 and 9 limit to a satisfactory extent any tendency there is for the tearing or fracturing to take place along the top circumference 6 instead of down the rim or skirt 2 as desired.
  • connection ll By having the connection l0 between the centre ridges ll of the corrugations I, when the seals are being applied to bottles and become slightly domed in the process, said connection ll allows the free end I 4 of the levering tongue 5 to be bent across the corrugations I as well as lengthwise therewith and thus apart from the sealing operation adding strength to the levering tongue (by becoming domed) the tongue 5 does not stick up or protrude to a distance or degree which would make the handling of the bottles more awkward than at present.
  • levering tongue 5 was made too narrow, there would not be enough strength across same (between the lines of severance 4 where they meet the top circumference 6) to prevent mere bending of said tongue without bursting of the rim, whereas if made too wide, insufiicient length of tongue would be obtainable for the levering action to be easily effected.
  • a bottle cap comprising a top part and an angularly disposed contractible skirt part, sealing means arranged in said cap, said top part being slit to form a tongue-like member, said slit having widely spaced portions extending to and terminating at the angle defined between the top and skirt parts, said skirt part being imperforate to preserve the sealing strength thereof, and reinforcing means extending substantially throughout the length of said tongue and beyond an imaginary line drawn across the ends of said slit whereby said tongue, when lifted, acts as a lever for applying a bursting strain down said skirt part.
