  • Publication number: 20150217331
    Abstract: A method for producing a plastic packaging container (10) in which a plastic packaging container (10) is formed by injection moulding, deep drawing and/or blow moulding, wherein the plastic packaging container (10) is coated and/or able to be coated with a barrier layer (40), and is produced with a cavity (12) suitable for accommodating a filling material, in particular a food product, and having a sealing zone (20), wherein in order to improve sealability with a sealing material, the surface of the sealing zone (20) is produced in such manner that an area of at least 50% of the surface thereof has a greater average surface roughness Ra according to DIN EN ISO 4288:1998 than the average surface roughness Ra according to DIN EN ISO 4288:1998 of an area of at least 50% of the inner surface (14) of cavity (12), and/or an area of at least 50% of the outer surface, particularly the lateral surface, of the plastic packaging container, and wherein the sealing zone (20) is produced having an average surface roughness

  • Patent number: 9061780
    Abstract: The invention relates to a packaging method for packing plastic injection moulded parts (9), including: simultaneously removing K parts (9) from K cavities (3), and depositing the parts (9) in an intermediate storage (5) and loading V packaging units (8), each having A parts (9), from the intermediate storage (5). A plurality of depositing positions (6) arranged next to each other in a deposition plane (7) is used as intermediate storage (5), and the K parts (9) are deposited equally divided among U subgroups (11) in the intermediate storage (5), and K parts (9) are removed from the K cavities (3) and are divided evenly among the U subgroups (11) until each subgroup (11) has L parts (9), wherein the quantity L of the parts (9) of a subgroup (11) corresponds to the quantity A of parts (9) to be loaded into a packaging unit (8), or an integral divisor of A. The invention further relates to a packaging device and to an injection moulding machine having such a packaging device.

  • Publication number: 20140331613
    Abstract: The invention relates to a packaging method and to a packaging apparatus by which plastic injection moldings designed in the form of pipette tips or medical reaction vessels are packaged in end packaging units. The invention provides for the operation of distributing the K plastic injection moldings over the sub-groups to take place in the at least one end packaging unit exclusively during the operation of filling the end packaging unit, and for plastic injection moldings to be distributed over the sub-groups until the at least one end packaging unit has been filled completely with in each case A plastic injection moldings.

  • Publication number: 20140331614
    Abstract: The invention relates to a packaging method by which plastic injection moldings designed in the form of pipette tips or medical reaction vessels are packaged in end packaging units. The invention provides that the K injection moldings are, prior to being distributed over the U sub-groups in the set-down plane, set down in a buffer store (12) by way of a second set-down apparatus (5) which is separate from the first set-down apparatus (18), in particular by way of a hose arrangement or by way of a gripper.
