Definitions

  • Another purpose of this invention is to provide a container opening device which may be readily grasped and operated, safely and without difficulty.
  • Another object of this invention is to provide a container assembly which may be sealed as tightly as desired without being concerned about possible detrimental effect upon opening qualities.
  • Yet another object of this invention is to provide a container which will provide a visual indication of any tampering or previous opening of the container.
  • FIGURE 1 is a perspective view of the sealed container having a type of opening device of the invention
  • FIGURE 2 is an enlarged sectional view of the container illustrating the opening device
  • FIGURE 3 is an enlarged sectional view of a wall member which is adapted to form a portion of the opening device
  • FIGURE 4 is an opening member adapted to cooperate with the wall member of FIGURE 3 to form the opening device;
  • FIGURE 5 is a plan view of an opening device employed with this invention.
  • FIGURE 6 is a view through 6-6 of the opening device illustrated in FIGURE 2.
  • a container 1 has a container wall 2 within which is disposed a removable portion 3 defined by at least one weakened or second line 4. Within the removable portion 3 is a raised boss or rivet 5.
  • the shank 8 of the boss 5 has a cross-sectional configuration which is substantially oval shaped.
  • the opening member is a disc 9 having an orifice 7 of substantially oval shape.
  • the disc 9 is rotated about the vertical central axis of the boss or rivet 5.
  • the shank 8 of the boss 5 and the orifice 7 of the disc 9 are oval in shape, after rotation is begun the smaller diameter d of the disc 9 will compressively engage a portion of the boss 5 of larger diameter.
  • the applied torque is thus converted to an inwardly directed compressive stress.
  • the tensile stresses across the container wall 2 are increased, with the weakened portion along the scored line 4 providing a line of least resistance to the tensile stresses.
  • the rivet illustrated is hollow, it is adapted to be deformed inwardly as the resistance of the score line residual is overcome and the score line 4 is fractured by the tension stresses resulting from the applied torque. Portion 3 may then be readily removed to permit access tothe container contents.
  • FIGURES 1 through 6 illustrate an opening device having a mechanical advantage which is equal to the outside diameter 0 of the disc 9 divided by the difference between the large diameter D of the boss or rivet 5 and the small diameter of the orifice d.
  • the opening device therefore, not only is adapted for ease of opening by a simple applied torque, without the need for independent implements, but also affords the added benefit of providing a mechanical advantage which produces high tensile stresses to effectively reduce the amount of torque which must be applied.
  • the height of the rivet 5 is by no means critical, so long as it is of suflicient size to permit deformation thereof to secure the opening member 9 against substantial translational movement with respect to the container wall.
  • a disc 9 as an opening member
  • the overlying position of the disc with respect to the container wall 2 will substantially reduce the amount of foreign particles which can accumulate in the score line and on adjacent wall portions. This acts to reduce the possibility of contamination of the contents upon opening of the container.
  • the disc 9 is readily accessible and may be grasped easily
  • a flange 10, which may be disposed upwardly, downwardly or angularly, may be provided. In the preferred form, it is knurled for improved ease of gripping.
  • frangible member 12 underlying the container wall so that the contents will remain sterile even after the removable portion is severed.
  • a hypodermic needle would pierce the frangible member to gain access to the contents.
  • an underlying rubber or plastic plug could be employed to provide additional protection for the container contents after opening has been effected and it could also function as a convenient reclosure where the contents are not entirely exhausted at the time of initial opening.
  • the closure is highly resistant to accidental opening as accidental application of a torsional moment required to open the container is most unlikely. Also, the design is such that it is unlikely that opening would be effected by the application of other types of forces which might be accidentally applied.
  • a container opening device comprising (a) a container Wall;
  • a container opening device comprising (a) a closure having a panel portion and a skirt portion;
