  • the preferred ramp portions are uppermost and the preferred shoulder portions below for a purpose that will be more fully described below.
  • a holding groove 8 and below the shoulder portion 4 of rib 2 is defined the retaining groove 9.
  • An annular rib 10 may also be provided on the container neck if desired.
  • the container includes on its neck 1 one or more guide members preferably above the ramp portion 7.
  • a pair of guide members 23 are provided equally spaced around the container neck, although it will be appreciated that any suitable num ber of guide members 23 may be provided.
  • the container cover member shown generally at 10 includes a central panel portion 11 which is shown in a preferred concave position.
  • the container cover members includes a peripheral skirt portion shown at 12 that extends over the upper neck portion of the container at 13. Sealing material as shown at 14 may be included to provide an hermetic seal between the container cover member and the container neck as will be appreciated by those skilled in the art.
  • the central panel portion 10 may include an intermediate sloped annular portion as at 15.
  • the cover holding member as above described has a cover encapsulating porLion shown generally at 16 and a depending ring portion at 17.
  • the cover encapsulating portion may take any suitable configuration but is preferably provided by an annular portion as shown.
  • the depending ring portion may be continuous or discontinuous and preferably is connected to the encapsulating portion 16 through a plurality of ribs shown at 18 which may be established in sets or groups as shown in the drawings.
  • the depending ring portion 17 may include one or more cover gripping projections.
  • a plurality af lugs 24 are provided for this purpose, located on the inner surface of the depending ring and adapted to abut against the edge of the peripheral skirt portion 12 thereto to hold the container cover member within the cover holding member.
  • three lugs 24 are provided equally spaced around the ring portion 17 although it will be appreciated that any suitable member may be provided. Preferably a different number of lugs 24 is provided to the number of guide members 23, and so that the spacing is different, for a porpose fully described below.
  • the depending ring portion 17 includes a container gripping rib 18a which preferably has an upwardly facing shoulder portion 19 and ramp portion 20.
  • FIG. 1 to 3 includes a tear strip 21 including a retaining extension 22.
  • the container cover member 11 is held within the cover holding member by the combined action of the encapsulating portion 16 and lugs 19.
  • the cover member 10 may be fitted therein by an easy flexing out of the depending ring portion 17.
  • the central panel portion 11 is free from movement up and down between a concave and convex position and therefore may be used to package materials within the container under vacuum where the central panel portion will be pulled into its concave position and when opened move upwardly and preferably with an audible click or other sound to indicate to the user that the package was under vacuum. This is a most important advantage that is not available in prior art plastic tamper proof closures.
  • the closure may be placed downwardly on the container neck.
  • the preferred upwardly sloping extension 22 will ride over the ramp 7 forcing the tear away strip outwardly but not severing it.
  • the ramp portion 20 of rib 18a will, meet the ramp portion 7 of rib 3 to force the depending ring portion 17 outwardly.
  • the ramp portion 7 will also assist in the projection 22 riding over rib 2. But it will be seen that when the rib 18a is in position within the groove 8 the shoulder portion 19 of the rib 18a will abut against the shoulder 5 of rib 3 to hold the parts together unless the depending ring portion 17 is pulled outwardly.
  • the projection 22 abuts against the shoulder 4 of rib 2 to hold the tear away portion in position until removed.
  • the lower portion of the tear away strip 21 may be closely adjacent the rib 10 of the container so that it is difficult for persons to apply a grip beneath the tear away portion 21.
  • the tear away portion 21 should first be removed before the closure can be removed from the container and this may be achieveu by any suitable method.
  • the tear away portion may be retained in its moved position or be totally removable as will be appreciated by those skilled in the art. Once the tear away portion has been removed it is possible to rotate the closure. This means that a lug 24 will meet a complementary guide member 23 which will push that portion of the ring portion 17 outwardly breaking the contact between the shoulder 19 and shoulder 5 in that zone. Thus the cloure may be pulled upwardly and removed from the container neck. The closure means may be reapplied to the container by pushing it downwardly as before.
  • the cover holding member is of deformable material and preferably a plastics material as known in the art.
  • the cover encapsulating portion shown generally at 26 may be comprised by an inner ring 27 and an onter ring 28.
  • a hinge portion is shown at 29 and a pair of connecting portions at 30 and 30'.
  • the preferred depending ring portion is shown at 31.
  • Joining web portions are shown at 32.
  • the outer ring portion 28 may include an indentation to provide an access means at 33.
  • Cover gripping ribs are shown at 34 and are preferably located beneath each of the joining web portions 32.
  • Sinusoidal gripping members are shown at 35 and are located beneath the expansion gaps shown at 36.
  • Figure 8 shows an expanded view of the sinusoidal gripping member showing flattened contact portion 37 and connecting portion 38 whereby it is 'connected to the ring 31.
  • the angle 6 as shown in the drawings is the angle referred to throughout this description. It will be seen that the container cover member is adapted to be placed over the preferred jar so that the sealing composition in the sealing recess 42 is located over the jar edge.
  • the preferred flange 43 extendes outwardly of the container edge.
  • the cover holding member is adapted to extend over the cover member.
  • the cover member is adapted to fit. within the cover holding member with the flange 43 located above the preferred cover gripping ribs 34 so that the cover members is retained within the cover holding member but removable therefrom as may be desired.
  • the gripping members 35 are adapted to abut against the container wall at points 37 to cause an outwardly extending expansion of the concertina members 35 and the associated ring 31 thus to create an inwardly directed returning force firmly to hold the cover holding member to the container wall as will readily be appreciated by those skilled in the art.
  • this embodiment provides a simple and inexpensive closure means for a jar-like container that can be readily. removed from and replaced onto the container. It can accommodate a 'pop top' feature. It does not require the use of an opening tool.
  • Figure 4 shows an example of an alternative container cover portion for use in the present invention.
  • a central panel is shown at 41.
  • 42 shows a sealing recess and 43 shows an outwardly flanged portion.
  • 44 shows sealing composition within the recess 42.
