Abstract: An apparatus for continuous heat transfer of ink images onto the outer surfaces of continuously moving articles, for example, generally cylindrical articles, from a length of continuously moving heat transfer sheet material having thereon a series of uniformly spaced heat transferable ink images. In the case of cylindrical articles, an elongated wrapping and heating tube is used for continuously wrapping a portion of the sheet material into intimate contact with the outer surface of each cylindrical article as the sheet material and the cylindrical members move through the tube and for heating the wrapped portion of the sheet material and the cylindrical articles during movement through the tube to cause transfer of the ink image to the articles within the tube. The sheet material is thereafter unwrapped and disassociated from the decorated cylindrical members after passing through the tube during continuous movement of the sheet material and the printed cylindrical members.

Abstract: A can printing machine of the type having a rotating assembly of mandrels contacting a rotating printing blanket for transferring decoration from the blanket to cans on the mandrels is provided with mandrel assemblies which are axially alignable with the printing blanket to permit axially uniform decoration of the cans. Each mandrel assembly comprises a rigid central member; a cylindrical sleeve mounted on the central member for receiving thereon a can to be printed; first mounting means pivotably mounting the sleeve to the central member at an axial midline of the can; and second mounting means accommodating pivoting and positioning the sleeve in a rest position to permit loading and unloading of the cans. Since the sleeve rotates relative to the central member to transfer circumferential decoration from the printing blanket to the can, the first and second mounting means permit rotation of the sleeve and rotatable pivoting.

Abstract: A plastic closure having inner pressure sealing skirt and outer finish engaging skirt has a plurality of fingers evenly spaced around the inner side of the outer skirt. The corresponding finish has a like plurality of indentations evenly spaced around its circumference for engagement by the fingers when the cap is applied. The indentations may be in the form of recesses spaced from the bottle mouth, having a horizontal lip at the top edge, and having a side wall smoothly merging with the outer surface of the finish at the side of the recess. Alternatively, the recess may be a bayonet groove spiraling downwardly on the finish and then bending into a horizontal or upwardly spiraling groove for locking the fingers in place against pressure in the bottle. Another embodiment would employ a groove spiraling downwardly on the finish at a first depth, and then terminating in a groove portion of a second greater depth.

Abstract: A secondary container packaging material for use in six pack can wraps, six pack bottle carriers, twelve pack carriers, etc., comprising a composite of a paper material laminated to a plastic film. The plastic film provides tear resistance to the composite, so that paper material may be used which has a tear resistance less than that of other secondary packaging paper materials. The reduced tear resistance allows the use of paper having a lower caliper, basis weight, and, therefore, cost than conventional secondary container packaging material. Natural kraft paper and recycled paper of 12-16 point caliper are preferred for use with the present composite. The plastic film may be 0.25-2 mils thick and is preferably formed of polyethylene terpthalate, polyethylene, polyvinylchloride, polypropylene, or cellophane. The preferred films are transparent and permit reverse printing on their inner surface to provide abrasion resistant decoration visible through the film.

Abstract: The continuous can printer and transfer apparatus is provided with infeed means devoid of moving parts, whereby cans move in a guided path by gravity through an inclined chute to stationary pockets on a rotatable pocket mandrel wheel where they are drawn from the pockets and seated by vacuum on mandrels which carry the cans to a printing blanket cylinder. Before contacting the rotating printing blanket, the surface speeds of the mandrel and printing cylinder are precisely matched by a pre-spin belt on the printing cylinder and rollers. Decorated cans are transferred to suction cups on a transfer wheel and discharged to a pin chain conveyor by a transfer assembly wherein all motions of the transfer cups are controlled in a radial and axial direction by a single cam motion.
