Abstract
The present invention is directed to an improved combination comprising a resealable container with a matching lockable lid and methods of formation "in-line" and use thereof. The container includes a rounded container lip near the top extremity of the container. The matching lid includes a substantially rounded lid lip which is slightly larger than and of substantially the same shape as the lip for the container. The transverse cross-sectional shape of the lid lip is that of a substantially smooth curve, and the transverse cross-sectional shape of the container lip for receiving, engaging and compressing the smooth curve of the lid lip is substantially V-shaped in order to exert force upon the smooth curve of the lid lip after mating engagement for effectuating a seal therebetween. The novel features of the container and lid hereof are such that they may be formed separately on separate machines or may in other embodiments be formed and used "in-line".
