Definitions

  • the invention relates to corking means for containers, particularly it relates to bottles crown caps with lines of weakness, tearing-strips and tags.
  • crown caps for corking bottles which made as a tin cap with a crowned skirt and provided with a tearing-tag which allows to uncork a corked bottle easy by means of removing a part of a back and the crowned skirt, which overlaps a neck of the corked bottle, along a line of weakness.
  • an elastic round laying is inserted inside the crown cap.
  • the plate can be formed as a simmetrical elongated tongue having a demicircular opening for a finger [patent CN 2090364U, 1992] or as a trapezium having the rounded corners [patent CN 2237607Y, 1996] or as an oval [patents CN 2115979U, 1993; CN 2090367U, 1992].
  • Known crown cap is choosen as a prototype of first three offered variants, it is provided with a round plate having the external diameter, which doesn't exceed diameter of a back of the crown cap, and laying on an outer surface of the back, where the round plate is connected to the back by means of a rivet and has an opening which is made to form a ring-shaped tab when the edge of the round plate is turning up [publication WO 00/51906, 2000].
  • crown caps having separate plate-tags have low ergonomic properties as follows:
  • a crown cap also is made from a sheet material as a cap with a crowned skirt, but a tag is made as a strip entirely with the crown cap, and one end of the strip is provided with a ring-shaped tag having and other end of the strip is conjugated with periphery edge of the crowned skirt.
  • a tag is made as a strip entirely with the crown cap, and one end of the strip is provided with a ring-shaped tag having and other end of the strip is conjugated with periphery edge of the crowned skirt.
  • crown cap which is provided with two lines of weakness made on the crown cap, these lines begin from places of the conjunction of the strip with the periphery edge of the crowned skirt with forming a tearing strip [patent GB 1139247, 1969].
  • Both the tag and the strip considerably support overall dimensions of the cap that creates technological difficulties during transportation of manufactured caps and corking bottles and also augments probability of involuntary uncorking of the corked bottle from a casual exposure. Also the probability of involuntary uncorking the corked bottle by means of casual external action is increased.
  • a crown cap is made as a cap with a crowned skirt and provided with a plate which carries out function of a bending tag and lays on an outer surface of a back of the crown cap, doesn't exceeding overall dimensions of the crown cap back, and which is fixed to the crown cap back by means of a rivet and has an opening therein.
  • a line of weakness is made on the crown cap, it begins from periphery edge of the crown skirt and comes to the periphery edge with forming a tearing strip having a hole for the rivet therein.
  • a length of an arc of the tearing strip from the beginning of the line of weakness up to its extremity does not exceed ⁇ /2 radian, that allows to detach the tearing strip without great efforts.
  • it may be an elastic round laying corresponding to diameter of a corking bottle neck which is inserted inside the crown cap.
  • the new feature for the first variant is that at least a part of edge of the plate and/or the opening is spinned in, and besides the plate lays on the outer surface of the back of the crown cap by its side which the edge bent by spinning in is located on, that excludes possibility of wound of the user. Since the height of the location of top of the plate in this case is augmented by thickness of the plate it it may be a dint in it for the head of the rivet, and in case the height of this head is no more than the size of the dint it is excluded the engagement or wound of the user by the head of the rivet or its edges.
  • the new feature for the second variant is that it is at least one tongue made on an outer surface of the crown cap back and inserted into the opening in the plate to come ito contact with an edge of the opening.
  • This tongue excludes possibility of of rotation of the plate around of the rivet and its getting out overall dimensions of the crown cap back (in case when the centre of the rivet is distinct from the centre of a circle of the crown cap back). From the point of view of manufacturing techniques (as punching) it is better to make this tongue having a spherical form. Also it is better when the height of the tongue does not exceed thickness of the plate.
  • the third variant it is a plate which is round as in the prototype, its external diameter does not exceed diameter of the crown cap back, and the opening is executed so to make a ring-shaped tab when the edge of the round plate is bending up.
  • the new features are that the opening has a ring nonclosed shape and is symmetric in relation to a diametrical axis of the round plate, and besides the hole for the rivet is located on said diametrical axis so, that it is in a segment of the round plate in which there is no the ring-shaped opening.
  • the crown cap may be remove from the bottle neck with using both the external ring-shaped tab and/or the internal tag having the shape of a part of a circle and formed along internal diameter of the opening. It is better when a length of an arc of the ring-shaped opening is ⁇ . . . 11 ⁇ /6 radian, and/or the centre of the ring-shaped opening coincides with the centre of the round plate, and/or the ring-shaped opening has the sizes relatively of external diameter of the round plate as follows: external diameter—0,5 . . . 0,9, internal diameter—0,4 . . . 0,85.
  • the ends of the ring-shaped opening may be rounded, and diameter of these rounds is more than width of the ring-shaped opening.
  • the internal tag 1 is bent more easy if external diameter of the ring-shaped opening conjugates with rounds smoothly.
  • crown cap may be made by a combination of any two or all three abovementioned variants.
  • the fourth variant is a crown cap for corking bottles which is made as a cap with a crowned skirt and provided with a round-shaped tag formed on a back of the crown cap entirely with it and having a round-shaped opening for finger therein. It is possible to separate the tag from the back along a nonclosed external generatrix whose ends are connected smoothly with non-intersecting lines of weakness which are ended on a periphery edge of the crowned skirt with forming a tearing strip having a width no more than greatest traversal size of the tag. An elastic round laying corresponding to diameter of a corking bottle neck is inserted inside the crown cap.
  • the new features are that a rigid round laying corresponding to diameter of the corking bottle neck is in addition inserted inside the crown cap before the elactic laying, and besides each of said layings has a plate-shaped form and is made with a recess opposite the opening, and also the tag is separated from the crown cap back by means of a slit located along the nonclosed external generatrix.
  • the rigid laying for example made of metal or plastic, does not allow to break through the fragile elastic laying casually, and the recess in it and the slit in the back allow to hitch the tag by the finger and to bend it easily.
  • the rigidity of the tag may be increased by using a stiffening rib made on the tag and located between edge of the opening and the nonclosed external generatrix, so convexity of the stiffening rib may be directed downwards or upwards. Also both the rigidity and safety of use may be increased when at least a part of edge of the opening is spinned in to inside of the crown cap.
  • the opening may be made in the form of an oval so that the greatest size of the oval is on a line which is perpendicular to axes of a symmetry of the tag, and the nonclosed external generatrix is equidistant to the oval generatrix so that distance between its extremities is less than the greatest size of the oval.
  • the rigid round laying may have an open excision formed as a truncated sector, in this case lateral sides of the sector are coincided approximately with the lines of weakness of the crown cap.
  • the fifth variant it is a crown cap for corking bottles which is made from a sheet material as a cap with a crowned skirt entirely with a tag-strip, that one end of the tag-strip is provided with a tag having an opening for finger and other end of the tag-strip is conjugated with periphery edge of the crowned skirt.
  • the tag-strip is bent so, that one its part lays on an outer surface of the crowned skirt and other part of the tag-strip lays on an outer surface of the crown cap back.
  • Two lines of weakness are made on the crown cap, they begin from places of the conjunction of the tag-strip with the periphery edge of the crowned skirt, with forming a tearing strip.
  • the new features are that it is the plate-shaped recess made on the crown cap back, the center of the plate-shaped recess coincides with the centre of a circle of the crown cap back, diameter of the plate-shaped recess is no more than internal diameter of a neck of a corked bottle and not less than diameter of circumscribing circle of the external generatrix of the tag, and the tag lays on the outer surface of the crown cap back in the place of the plate-shaped recess and does not extend over the external sizes of the plate-shaped recess.
  • the tag extends above a surface of the crown cap back less, and also the tag is in addition fixed by lateral walls of the plate-shaped recess that reduces the possibility of self-uncorking by means of a casual external force and the coupling with other subjects during transportation and storage.
  • It may be a round- or ring-shaped elastic laying corresponding to diameter of a corking bottle neck, which is inserted inside the crown cap.
  • the plate-shaped recess may be made round on a plan view.
  • depth of the plate-shaped recess is approximately equal to thickness of the sheet material.
  • the lines of weakness may form the tearing strip which is symmetric in relation to a diametrical axis of the crown cap back (narrowed, extending or with equal width).
  • line of weakness by all five variants may mean a continuous line as well a dash line, for example which is made by punching with floturning, other words by decrease of thickness of the sheet material of the crown cap.
  • FIG. 1-3 show a crown cap having a separate combined tag: FIG. 1 is its top plan view, FIG. 2 is its increased vertical cross-sectional view taken along the line A-A of FIG. 1 , FIG. 3 is its increased local side view I of FIG. 2 .
