초록 ▼

The open top of a container is surrounded by a rim having a curved upwardly presented surface and a slight ridge projecting upwardly from the curved surface. A seal membrane containing a metal foil extends over the open top of the container and seats against the ridge on the container rim. A flexible lid fits over the membrane and interlocks with the rim so that the membrane is interposed between the ridge and the lid. The lid has a downwardly opening annular groove which receives the container rim and this causes the seal to wrap generally around the curved upper surface of the rim. Once the lid and membrane are in place, the membrane is induction heated above the melting point of the container material, while a downwardly directed force is applied to the lid. The ridge, which is in contact with the seal membrane, melts down and thereafter is allowed to cool while the force is maintained on it, so that when the material solidifies, it is bonded to the membrane.

대표청구항 ▼

The combination comprisng: a container having an upwardly presented opening and a rim surrounding the opening and being formed entirely from a nonmetallic material, the rim having a convex upwardly presented surface; a flexible seal membrane extended over the open top of container as well as over the convex upwardly presented surface of the rim, the membrane including a metal foil which is at least located in the area of the membrane overlying the rim of the container so that the membrane may be induction heated to a prescribed temperature by placing it in a magnetic field which undergoes rapid reversals in polarity; a nonmetallic sealing material interposed between the convex surface of the rim and the foil of the membrane, the sealing material being capable of becoming plastic when heated to the prescribed temperature, the sealing material being plastically deformed between and adhered to the foil and the rim at the convex surface as a result of the foil being induction heated to the prescribed temperature and forced toward the rim with plastic deformation being sufficient to effect a seal between the opposed surfaces of the membrane and rim; and a lid including a cross portion which overlies the membrane and the container rim and a downwardly projecting skirt at the periphery of the cross portion with the skirt fitting snugly around the rim, the cross portion having a preformed groove which aligns with and is directly above the rim with the groove being defined in part by continuous beveled side surfaces which downwardly diverge and are spaced sufficiently apart to enable the rim to be partially received in the groove when the skirt is around the rim, the side surfaces of the groove being arranged to confine the membrane such that it generally follows the contour of the convex upper surface of the rim for a substantial distance in the lateral direction.
