Definitions

  • This invention relates to packaging and particularly to a container with a closure means.
  • the invention can be applied to several kinds of containers having an opening adapted to be closed.
  • this invention provides a closure means for a container with an opening, e.g. a bottle, including an inwardly turned lip established in the region of the container opening and a cap having a lid portion and a tubular plug portion, said plug portion at its end remote from said lid portion being provided with a flange, either the container, at least in the region of its opening, or the cap or both being elastic, the tubular plug portion of the cap being insertable into the opening of the container, thereby to press the said lid portion against the top or shoulder of the container and to cause an edge of the lip to engage said flange, the said elastic properties being utilized for effecting a tight seal between said edge and said flange, characterized by the cap being provided with a frangible portion, along which the lid portion is removable, and by means for retaining the tubular plug portion in the opening of the container when the'lid portion has been removed.
  • FIG. 1 is a front elevational view of a container with a closure means
  • FIG. 2 is a vertical sectional view of the embodying the invention.
  • FIG. 3 is a portion of FIG. 2 on a larger scale.
  • the improved package comprises the bottle 1 with its cap 2.
  • the top or shoulder of the bottle adjacent the opening is shaped in a special way to obtain a completely tight seal.
  • the bottle top or shoulder together with the cap is accordingly included in the concept of closure means.”
  • the shape of said closure means will be apparent from FIG. 2 showing a section through the same.
  • the shoulder or top of the bottle extends inwardly towards the center of the bottle-opening and downwardly towards the bottle bottom forming a lip 6.
  • the bottle, or at least the lip 6, is most advantageously made of an elastic material, erg. a plastic, the resilient properties of which ,being utilized. The realization of this will be apparent from the following.
  • the lip 6 presents a sharp edge 7 towards the bottom.
  • the cap 2 consists of two main portions: a lid portion 3 and a tubular plug portion 5 connected to each other closure means by a frangible portion 12.
  • the cap 2 is most advantageously made of elastic material, said lid portion thereby creating a cap spring and said tubular plug portion a tube'spring.
  • the tubular plug portion is .at its bottom end provided with a flange 8 having a bevel 9. Between said flange 8 and said lid portion 3 there is an additional flange 10. Furthermore a groove 11 is proat its lower end. Between the flanges 8 and is a recess 1 surfaces defining such opening.
  • the tubular plug portion 5 By pushing downwardly at the center of the lid portion 3 by a'device not shown, the tubular plug portion 5 is inserted into the opening of the .bottle to engage the inclined lip '6. Meanwhile the cap spring, i.e. the lid portion 3, will be stressed. As lip 6 is pushed further and further aside by entry of the bevel 9, the flange 8 will eventually entirely pass the lip 6, whereupon the lip 6 will then snap over the flange 8.
  • the lid portion 3 the total diameter of which is somewhat larger than the diameter of the top portion of the bottle, has a little earlier come into contact with the bottle.
  • the point of contact is in FIG. 3 indicated by number 13.
  • the last phase of inserting is, besides by friction counteracted by two forces, viz, the force between the lip 6 and the bevel 9 and the compressive force between the lid portion 3 and the bottle 1 and must be increased tending to tension the cap spring still more.
  • the lip 6 has snapped back into the recess between the two flanges 8 and 10
  • the container is closed.
  • the edge 7 engages the upper surface of the flange 8- in the corner defined by the neck portion of the tubular plug portion 5 and the upper surface of the flange 8.
  • a completely tight seal is maintained by three forces, viz the spring forces of the lip 6; the plug portion 5; and the lid portion 3. 1f pressure prevails within the package, as is the case when the filling material consists of an aerated liquid, the tightness of the closure is further increased. This is due to the fact that a pressure on the inner surface of the lid portion will arise effecting an upward force on the tubular plug portion amplifying the force between said edge 7 and said flange 8.
  • the engagement of the lid portion at 13 also protects the opening from contamination.
  • the tearing open of the package will be carried out in the following way. Through seizing the handle 4 and pulling it upwards, if the pulling force is great enough,
  • the lid portion 3 will be torn off from the tubular plug portion 5 along said frangible portion 12.
  • the rupture occurs at the narrowest part of the frangible portion 12 substantially avoiding burrs in the rupture surface.
  • the tubular plug portion will remain in the opening of the container, as removal of this portion is prevented by the flanges 8 and 10. Due to the fact that the portion 5 remains in the opening this will provide an attractive appearance because the sharp edge 7 is concealed, and the package will have good-pouring qualities, because the contents of the package when dispensed does not follow the inwardly turned lip 6 and the outside of the package wall 1.
  • the rupture in the frangible portion 12 between the lid portion 3 and the tubular plug portion 5 will function as a pouring edge for the contents of the package which preferably consists of a liquid. Moreover the flange It) prevents the tubular plug portion from dropping into the interior of the container when the lid portion has been removed.
  • a cap for said opening comprising a lid portion engaging said shoulder and a tubular, integral plug portion extending into saidopening, said plug portion having a first flange adjacent to the lower 'end thereof which'is of greater outer diameter than the inner diameter of said lip and is positioned below said lip with its upper surface engaging said lip, said plug portion having a'second flange of greater outer diameter than the inner diameter of said lip spaced from said first flange by a first annular recess and positioned above said lip, said plug portion having a second annular recess between said second flange and said lid portion which eX- itends inwardly beyond the surface of said first recess defining a frangible portion between said lid portion and said plug portion, at least one of said container and said cap being elastic and the vertical distance between the upper surface of said first flange and the lower surface of said lid portion in unstressed condition being
