Abstract
Abstract Reclosable lid frame having a continuous downwardly open groove (4) for receiving an upper edge part of a container and a quantity of connecting and sealing material for securing the lid frame to the container. At least the inner side wall of the groove is inclined upwardly and inwardly of the groove and has a plurality of integral spaced apart and upwardly extending ribs projecting therefrom. The ribs are substantially triangular with the longest side of each rib integral with the inner side wall of the groove. The ribs guide the lid frame into assembly with the container and cooperate with the inner side wall to define spaces for receiving connecting and sealing material as the lid frame is moved into assembly with the container.

Claim 1
Independent Claim
268 words
Reclosing arrangement for a container (9) of cardboard, plastic or sheet metal and of the type which is adapted to be connected to a lid frame (2) having an all around extending and downwardly open frame groove (4) in which a squarely cross cut top part of the container is to be introduced and secured in position by means of glue, wax, hot-melt or a similar connection and sealing material, and in which a reclosing lid (1) is adapted to be connected inside or outside the lid frame (2), in particular under a powder proof or steam proof condition, characterized in that at least the inner wall (5) of the frame groove (4) tapers inwardly into the frame groove and in the direction towards the upper end (7) of the frame groove (4), in that at least the inner wall (5) of the frame groove (4) is formed with several ribs (12) extending mainly in the direction of introducing the container (9) in the frame groove (4), and in that the ribs (12) are formed with a lower, tapered upwards and to the inner portion of the frame groove (4) extending entering part (15) for facilitating the introduction of the container sliding on the edges of the ribs (12) of the frame groove (4), and an upper rib part (16) forming side walls for a volume of connection and sealing material and against the edges of which the container is likewise adapted to slide when being introduced in the frame groove (4), thereby preventing the connection and sealing material from being forced out of the frame groove (4).
