Abstract
A container which has a top with two concentrically mounted lids, a first lid attached to and sealing the container and a second lid rotatably mounted to the first lid. The first lid has a weakened surface region formed by scoring, scribing or grooving. The first and second lids have nested embossments which are interengageable to apply a predetermined pressure to fracture the weakened region and form a pour aperture in the first lid when the second lid is rotated relative to the first lid. The second lid also has an aperture which is brought into an overlying relationship with the aperture in the first lid when the second lid is rotated relative to the first lid, thus allowing the contents of the container to be dispensed.
Claims42
A container comprising side walls, a bottom and a top, said top comprising a first lid joined to the side walls, said first lid comprising a single layer of homogeneous composition sealing said container, said first lid Being substantially planar and having a raised surface portion eccentrically disposed thereon, a weakened region surrounding said raised surface portion and a second lid, said second lid being substantially planar and being rotatably mounted on the top of the first lid for relative motion with respect to said first lid, means on said second lid interengageable with said raised surface portion on the first lid and being positioned to interengage and fracture said weakened region to form an aperture in said first lid defined by said weakened region upon rotation of the second lid relative to the first, said second lid having an aperture being positioned to move into overlying relationship with the aperture in the first lid upon further rotation of the second lid relative to the first.
A top for use with a container for beverages said top comprising a first lid, said first lid having a substantially planar upper surface of a relatively thin metal and having a first raised surface portion eccentrically disposed thereon, a narrow fracture zone surrounding said raised surface portion and a second lid, said second lid being substantially planar and being rotatably mounted on the top of the first lid for relative motion with respect to said first lid, said second lid having a second raised surface portion and an aperture adjacent thereto, said first raised surface portion being nested within said second raised surface portion, the raised surface portions having walls positioned to interengage and fracture said fracture zone to form a pour aperture in said first lid defined by said fracture zone upon rotation of the second lid relative to the first, said aperture in said second lid being positioned to overlie with the aperture in the first lid upon further rotation of the second lid relative to the first.
A beverage container comprising side walls, a bottom and a top, said top comprising a first lid joined to the side walls, said first lid being substantially planar and having a raised surface portion disposed thereon, a groove surrounding said raised surface portion and a second lid, said second lid being substantially planar and being movably mounted on the top of the first lid for relative motion with respect to said first lid, said second lid having a second raised surface portion interengageable with the raised surface portion of the first lid upon relative rotation of the second lid with respect to the first, said second lid having an aperture adjacent to said second raised surface portion, said aperture being angularly displaced from the groove in the first lid, said second raised surface portion being positioned to interengage and fracture the raised surface portion of said first lid at said groove to form an aperture upon motion of the second lid relative to the first, said aperture in said second lid being positioned to provide the aperture in the first lid a pour aperture for the beverage upon further motion of the second lid relative to the first.
