Abstract A positioning and placement device for the application of square covers to square containers which device basically includes a cover supply section for maintaining a supply of covers, a positioning and registration section to provide individual covers in proper relation to the square containers which are being moved thereunder and an application section which is arranged to remove the cover from the positioning and registration section and forceably engage the cover with a container as the same is being moved therepast in a manner to insure sealing therebetween on all edges thereof. The device particularly includes unique positioning and registration means for locating the covers with respect to the containers and unique placement means which not only forces the covers properly onto the containers but which also removes the covers from the registration and positioning section.

Claim 1
Independent Claim
280 words
A device for automatically positioning and placing generally rectangular covers on generally rectangular containers including: a. a cover application section for positively positioning a generally rectangular cover onto a generally rectangular container received into said section; b. a cover supply section including means for retaining a plurality of covers in a supply position; c. a positioning and registration section arranged intermediate said supply section and said application section, said positioning and registration section including a first ramping plate arranged in parallel, spaced relation to said cover supply section and a second camming plate arranged angularly to said ramping plate and said application section, whereby a cover may be transferred to said ramping plate and will slide therefrom onto said camming plate; d. transfer means arranged to select a single cover from said supply and transfer the same to said positioning and registration section; e. positioning and registration means provided at a selected portion of said camming plate arranged to contact and receive a portion of a cover delivered thereto from said ramping plate and retain the same thereon with a portion of the cover extending into said application section and positioning the cover in spaced relation to the cover receiving portion of a container received into said application section; f. application means provided in said cover application section arranged to forceably shift the extending portion of the cover into sealed relation with the container and simultaneously shifting the cover from said positioning and registration means to permit the cover to be removed from said positioning and registration section; and, g. means for moving the container and cover past said application means whereby the entire cover is sealed to the container.
