DETAILED DESCRIPTION OF THE DRAWINGS
(29) Referring first to
(30) Base 12 has upwardly extending sidewalls 18 defining an opening 20 through which products are inserted into container 10 before lid 14 is closed. At the top end of walls 18 of base 12 are rims 22 (refer
(31) Lid 14 in this embodiment has a first planar area 24 which, in this embodiment, comprises virtually the whole of lid 14. The second planar area is formed by rim portion 26 which, as can be seen in
(32) In the closed position, illustrated in
(33) As can be seen in
(34) Turning now to the second embodiment illustrated in
(35) Lid 44 has a first planar area 54 defined by ribs 38 and edges 55.
(36) A single label (not shown) can extend over the whole of first planar area 54 and both second planar areas 56. Alternately, two separate labels may be used, the first covering part of first planar area 54 and one of the adjacent second planar areas 56, while the over covers part of first planar area 54 and the adjacent second planar area 56, leaving free central portion 46 of lid 44.
(37) As shown in
(38) In this embodiment, lid 44 also includes removal tabs 62, to assist in removing lid 44 from base 42.
(39) Container 40 may include vents (not shown) and depression 64 in floor 66 of base 42, as desired (refer
(40) A third embodiment is shown in
(41) The next embodiment in
(42) Similarly, flat portions 78a are located at comers of base 72a.
(43) As was the case with the previous embodiment, when lid 74a is closed on base 72a, flat portions 78a are substantially co-planar with first planar area 68a.
(44) The next embodiment shown in
(45) Expanded rim 86 is designed so that, when lid 84 is closed on container 82, expanded rim 86 is substantially co-planar with lid 84, which in this embodiment comprises the first planar area.
(46) As can be seen in
(47) The embodiment in
(48) Container 70b has base 72b and lid 74b, hinged at 16. Cut-away 76b on lid 74b is designed to expose flat portion 78b on base 72b in the closed position (
(49) This embodiment includes lock lugs 92 designed for a friction fit into lock recesses 94 on base 72b. As can be seen from
(50) The embodiments in
(51) Referring first to
(52) Base 102 has rim 22 which has extension 108, in use inclined at an obtuse angle from rim 22.
(53) In the closed position, extension 106 is designed to mate with extension 108. Extension 106 has one or more cut-outs, similar to those already illustrated in
(54) The embodiment in
(55) In the closed position, extension 106a mates with extension 108a along margin 98 to provide a substantially co-planar surface 96 on which a label 60 (not shown) may be placed to seal lid 104a to base 102a.
(56) It will be apparent to one skilled in the art that the embodiments in
(57) Reference is now made to the embodiment in
(58) Each of lid parts 114a and 114b has a pair of cut-aways, 116a and 116b. When lid parts 114a and 114b are in the closed position as shown in
(59) Referring now the embodiment in
(60) Base 122 has formed sections 128, the top, flat part of which comprise the second planar areas. As can be seen by
(61) The embodiment in
(62) It will be appreciated from the various embodiments described above that the container can be produced in a wide number of forms and that, in addition, a single form may be suitable for application of different types of labels. Lids may be hinged or separate.
(63) Lids may be substantially flat or they may be shaped, with ridges, ribs, domes as non-limiting examples of shaping. Especially in the case of substantially flat lids, these may be designed to mate with the base so that the second planar area or areas can appear on, for example, opposing sides of the lid, opposing comers of the lid or on one side of the lid, opposite the hinge. In the case of a lid which is a dual lid, with two hinges, the second planar areas may be on two opposing sides (viewing the closed lid in plain view), or on four comers, for example.
(64) In the case of a separate lid, once again viewing the container in plain view in the closed position, the second planar areas may be in each of four comers, on two opposing sides, on two diagonal comers, around all four sides or separately on each of four sides. These are a selection only of possible combinations. Others will be apparent to one skilled in the art.
INDUSTRIAL APPLICABILITY
(65) The container can be adapted to any currently known container design, whether having a single lid or a multi-part lid. The embodiments allow for manual or high speed automatic closure and flat, self-adhesive label application providing tamper evidence, while at the same time employing a minimum number of moving parts.
(66) The container can offer important tamper evidence capabilities while maintaining minimal obstruction of vision through the container lid. For certain applications, the container will also allow alternate graphic methods to be successfully used, such as pre-printing, branding and nutritional information onto the lid area, thus reducing label requirements to a smaller, basic tamper evident label only.
