DETAILED DESCRIPTION

[0021] Example embodiments have been described above. Those skilled in the art will understand that changes and modifications may be made to the described embodiments without departing from the true scope of the present invention, which is defined by the claims.

[0022] FIG. 1A is a perspective view of container 100 with lid 120 in an open position attached to base 110, according to an example embodiment. Lid 120 is attached to base 110 with a living hinge between flanges extending from the lid 120 and the base 110. FIG. 1B is a close up view of the container 100 shown in FIG. 1A. The extending flange on the base 110 includes a first perforation cut or score cut 150. The extending flange on the lid 120 includes a plurality of bubbles or raised portions 130 that extend over the perforation cut or score cut 150 when the lid 120 is in a closed position over base 110. A plurality of raised assist beads 140 are positioned adjacent the first perforation cut or score cut 150. It will be appreciated that the perforation cut or score cut 150 may alternately be positioned on the extending flange of the lid 120, and that the bubbles or raised portions 130 may be positioned on the extending flange of the based 110.

[0023] FIG. 2A is a another perspective view of container 100 shown in FIGS. 1A and 1B with the lid 120 in a closed position with respect to the base 110. FIG. 2B is a close up view of the bubbles or raised portions 130 positioned over a first perforated cut or score cut on flanges of beverage container 100 shown in FIGS. 2A. A second perforation cut or score cut 155 is positioned around bubbles or raised portions 130. When lid 120 is closed with respect to base 110, there is a tight fit between the lid 120 and base 110 on a side opposite from where the extending flanges are positioned, so that the lid may not be removed from the base from that side. There are no tabs on this side to allow for opening of the lid off of the base. To remove the lid 120 from the base 110, the bubbles or raised portions 130 are depressed to break the first perforation cut or score cut 150. Raised assist beads 140 assist in breaking the first perforation cut or score cut 150. Once the first perforation cut or score cut 150 is broken, the extending flange on the lid 120 serves as a tab to effect removal of the lid 120 from base 110. The bubbles or raised portions 140 are advantageously deformed upon depression such that the when the lid 120 is placed back onto the base 110, the deformed bubbles or raised portions 130 provide a visual indication that the lid has been removed from the base and the container 100 has been opened, or tampered with.

[0024] FIG. 3A is a perspective view of container 100 after the first perforation cut or score cut 150 has been broken with the lid 120 unattached to the base 110. FIG. 3B is a close up view of the lid 120 shown in FIG. 3A. In FIGS. 3A and 3B, raised portions 130 are positioned on a flange extending from the lid 120. Raised portions 130 could alternatively be positioned on a flange extending from the base 110. A second perforation cut or score cut 155 is advantageously positioned partially around raised portions 130. Upon depression of the bubbles or raised portions 130, the second perforation cut or score cut 155 positioned partially around the bubbles or raised portions is at least partially broken, to provide a visual indication that the container has been opened, or tampered with. The second perforation cut or score cut 155 positioned partially around the bubbles or raised portions 130 is weaker than the first perforation cut or score cut on the extending flange of the base 110, such that the second perforation cut or score cut 155 around raised portions 130 is at least partially broken before the first perforation cut or score cut 150 on the extending flange of the base 110 is broken. The at least partial breakage of the second perforation cut or score cut 155 positioned partially around the bubbles or raised portions 130 provides a visual indication that the container has been opened, or tampered with. As shown in FIGS. 3A and 3B, the bubbles or raised portions 130 advantageously remain attached to the flange which provides an environmental advantage in that the bubbles or raised portions 130 remain attached and do not completely separate from the flange.

[0025] FIG. 4A is a perspective view of container 100 with lid 120 separated from base 110. In the embodiment shown in FIGS. 4A and 4B, the second perforation cut or score cut 155 extends completely around bubbles or raised portions 130, such that when the bubbles or raised portions 130 are depressed, the raised portions are completely removed from the extending flange of lid 120. The complete removal of bubbles or raised portions 130 of the extending flange of lid 120 serves to provide a visual indication that container 100 has been opened, or tampered with. The second perforation cut or score cut 155 around raised portions 130 is weaker than the first perforation cut or score cut 150 on the extending flange on the base 110, such that the second perforation cut or score cut 155 around the bubbles or raised portions 130 is broken before the first perforation cut or score 150 on the extending flange on the base 110 is broken.

[0026] FIG. 5A is a top view of container 200, with an alternate arrangement of bubbles or raised portions 130. In FIG. 5A, container 200 is a round container. FIG. 5B is a side view of raised portion 130′. FIG. 5C is a side view of raised portion 132, and FIG. 5D is a side view of raised portion 134. In FIG. 5B, raised portion 130′ has a flat top surface and extends over raised assist bead 140. In FIG. 5C, raised portion 132 has a half spherical bubble extending above raised assist bead 140. In FIG. 5D, raised portion 134 is configured as an oval-shaped member extending over raised assist bead 140.

[0027] It will be appreciated that the bubbles or raised portions 130 and raised assist beads 140 may vary in size, shape, and number. The examples provided herein, are exemplary, and do limit the bubbles or raised portions 130 and raised assist beads 140 are not limited to any particular size, shape, or number shown in the Figures.
