摘要:
An in-mold labeler (24) and a method for in-mold labeling a rotary plastic blow molding machine (22) includes a dispensing assembly (38) having a dispensing wheel (42) that is rotatably mounted on a base (40) and supports a plurality of dispensing head assemblies (46) each of which includes a support (48) and a dispensing head (50). An actuator (56) including a first cam mechanism (58) and a second cam mechanism (64) moves the support (48) of each dispensing head assembly (46) along the rotary path of movement of an adjacent open mold (30) of the blow molding machine and angularly positions the support in alignment with a moving mold parting plane of the adjacent open mold in a manner that permits high speed operation of the in-mold labeling.
摘要:
An expanded content label (ECL) having multiple layers and a heat-activated adhesive. The ECL is intended for use in an in-mold labeling process. A method for applying the ECL includes placing the ECL in a mold, molding an article within the mold thereby activating the adhesive, and removing the article with the label adhered thereto from the mold.
摘要:
A squeezable tube-shaped plastic container (10, 100) having a one-piece construction formed by extrusion blow-molding techniques. The container (10, 100) has a retractable end wall (26, 126) which is positionable into an outwardly projecting position and an inverted position. The end wall (26, 126), as blown, is in the outwardly projecting position and is thereafter inverted so that a tamper indicating covering (28, 128) can be attached to the end (14, 114) of the container (10, 100) thereby sealing the end wall (26, 126). The inverted end wall (26, 126) permits the container (10, 100) to be free standing on the standing ring (20, 120). In use, the flexible sidewall (12, 112) of the container (10, 100) is squeezed to snap the end wall (26, 126) from the inverted position to an outwardly projecting position to enable ready access to a dispensing opening (32, 132) on the end wall (26, 126). An efficient and cost effective method for forming the container (10, 100) and an intermediate article (44) formed during the method are also disclosed.
摘要:
A method and apparatus for applying labels to cylindrical portions of plastic bottles by in-mold labeling utilizes an indexing label magazine which dispenses labels to first label engaging heads and, following indexing of said label magazine, dispenses labels to second label engaging heads.
摘要:
Diffuse reflective materials proximate to a structure formed by thermally induced phase separation of a thermoplastic polymer and a diluent providing enhanced flexibility and reflectivity especially in the visible wavelengths of 380-730 nanometers are described. Such materials find a wide variety of application among combinations with other reflective layers. The diffuse reflective articles are useful in backlight units of liquid crystal displays, lights, copy machines, projection system displays, facsimile apparatus, electronic blackboards, diffuse white standards, photographic lights and the like.
摘要:
A method of enhancing the three-dimensional effect of a plastic part and the label used therewith is disclosed. A label for enhancing the three-dimensional visual effect which comprises a plastic core and/or, an insulating layer, and/or a heat-activated adhesive backing is disclosed. The label is aligned on the surface of a relieved mold. When plastic is forced against the back surface of the label, the label is stretched and forced into the relief along with the plastic. The label adheres to the plastic part by either a heat-activated adhesive backing or the core forms a melts/weld interface with the molded part creating a permanent bond between the label and the molded part.

A plastic blow molding system (20) and a method for blow molding utilize an in-mold labeler (24) and a method for in-mold labeling a rotary plastic blow molding machine (22) includes a dispensing assembly (38) having a dispensing wheel (42) that is rotatably mounted on a base (40) and supports a plurality of dispensing head assemblies (46) each of which includes a support (48) and a dispensing head (50). An actuator (56) including first and second cam mechanisms (58, 64) moves the support (48) of each dispensing head assembly (46) along the rotary path of movement of an adjacent open mold (30) of the blow molding machine and angularly positions the support in alignment with a moving mold parting plane of the adjacent open mold in a manner that permits high speed operation of the in-mold labeling. Label transfer apparatus (160) provides high speed labeling of the dispensing assembly.
摘要:
In-mold-labeling method and apparatus for labeling a plurality of cylindrical bottles simultaneously by withdrawing the end label from each of a plurality of spaced apart lanes of a label magazine, moving the transfer mechanism supporting such labels to a position aligned with the recesses of a mold and inserting a label in each of said recesses. The support mechanism with vacuum heads carrying adjacent labels causes adjacent vacuum heads to be moved to a position closer together when aligned with the mold recesses than when aligned with the respective lanes of the label magazine.
摘要:
A dispensing head (36) for an in-mold labeling system includes a lever assembly (106) rotatively driven by a rotary drive member (74) and having a pair of levers (108) that are adjustable with respect to the rotary drive member independently of each other. Each lever (108) has a cam and follower connection (112) to an associated label carrier (38) such that rotation of the rotary drive member (74) provides movement of the label carriers (38) between retracted and label transfer positions.
摘要:
An in-mold labeling system for use with a rotary blow molding machine (10) includes first and second electrical servomotors (46, 64) and first and second cam mechanisms (48, 66) respectively driven by the servomotors to move a dispensing head (36) between supply and delivery locations and to move a label carrier (38) on the dispensing head between retracted and label transfer positions independently of each other. A sensor (92) of the system senses rotation of a rotary wheel (12) of the machine to operate first and second electrical controllers (84,86) that respectively operate the first and second electrical servomotors (46,64) in coordination with the machine operation but independently of each other.
