A bubble 6 formed in the wall 7 of a plastic container having, an interior surface 8, an exterior surface 9 and a wall thickness 29 and being suitable for containing a liquid under pressure e.g., a carbonated beverage, including an integral structure formed of a central dome 10 having a convex outer surface 11 facing toward the adjacent exterior surface 9 and connected with an annular trough 18 having an annular concave surface facing the adjacent the exterior surface 9, a frustum 20 interconnecting the trough 18 with the dome or an outer ring of curved cross-section, the outer ring having an annular concave surface facing toward the interior 14, integrally formed with the container wall 7 surrounding the bubble, the bubble having a thickness approximately equal to the wall thickness. An associated container, blow mold and method are also included.
A bubble (6) formed in a wall (7) of a plastic container, the wall (7) defining an interior (14) of the container and having an interior surface (8), an exterior surface (9) and a wall thickness (29), the container being suitable for containing a liquid under pressure and the bubble comprising an integral structure having a central dome (10) defining a convex outer surface (11) facing toward an adjacent portion of the exterior surface (9), an annular trough (18) connected with the central dome (10), an outer ring (22) of curved cross-section and a first frustum (16 or 20) interconnected with the trough (18) and one of the central dome (10) and the outer ring (22), the annular trough (18) having an annular concave surface facing the adjacent portion of the exterior surface (9) and the outer ring having an annular concave surface facing toward the interior (14) of the container, to join, integrally, the bubble to the container wall (7) surrounding the bubble, the bubble having a thickness about equal to the wall thickness (29).
A plastic container suitable for containing a liquid under pressure, comprising at least one bubble (6), formed in a wall (7) of the plastic container, the wall (7) defining an interior (14) of the container and having an interior surface (8), an exterior surface (9) and a wall thickness (29), the bubble comprising an integral structure having a central dome (10) defining a convex outer surface (11) facing toward an adjacent portion of the exterior surface (9), an annular trough (18) connected with the central dome (10), an outer ring (22) of curved cross-section and a first frustum (16 or 20) interconnected with the trough (18) and one of the central dome (10) and the outer ring (22), the annular trough (18) having an annular concave surface facing the adjacent portion of the exterior surface (9) and the outer ring having an annular concave surface facing toward the interior (14) of the container, to join, integrally, the bubble to the container wall (7) surrounding the bubble, the bubble having a thickness about equal to the wall thickness (29).
A blow mold for blow molding a plastic container for containing a liquid under pressure, comprising at least one bubble (6) formed in a wall (7) of the plastic container, the wall (7) defining an interior (14) of the container and having an interior surface (8), an exterior surface (9) and a wall thickness (29), the bubble comprising an integral structure having a central dome (10) defining a convex outer surface (11) facing toward an adjacent portion of the exterior surface (9), an annular trough (18) connected with the central dome (10), an outer ring (22) of curved cross-section and a first frustum (16 or 20) interconnected with the trough (18) and one of the central dome (10) and the outer ring (22), the annular trough (18) having an annular concave surface facing the adjacent portion of the exterior surface (9) and the outer ring having an annular concave surface facing toward the interior (14) of the container, to join, integrally, the bubble to the container wall (7) surrounding the bubble, the bubble having a thickness about equal to the wall thickness (29).
A method of producing a bubble (6), in a plastic container suitable for containing pressurized liquids, which does not, in use, extend outwardly from the exterior surface of the container, comprises:
