Claims

1. A transporter for the suspended transporting of containers (2) along an at least partially linear transport path (3) in an at least single-lane container flow and in a transport direction (A), having a plurality of container carriers (6) each comprising at least one container holder (8), with the container carriers (6) being oriented with their longitudinal extension horizontal and square to the transport direction (A) and able to be moved incrementally or cycled by at least one drive or transport element (7) in the transport direction (A), the container carriers (6) each being attached at both ends to a transport element (7) which forms a closed loop, is oriented with the loop plane parallel to the transport direction (A) and is endlessly cycled or incrementally driven, with the container holders (8) each being formed by recesses or grooves (9) accommodating the containers (2) at a container region (2.2) beneath their container mouths (2.1); on one edge, said recesses or grooves form support surfaces (12) each for a container flange (2.3) for a suspended holding of the containers (2) on the support surfaces (12), and with the recesses or grooves (9) which form the container holders (8) each comprising, at a front groove end when seen relative to the transport direction (A), a groove opening (10) for the introducing and removing the containers (2) into and out of the container holders (8) and being closed at a rear end when seen relative to the transport direction (A), characterised in that the respective groove opening (10) comprises a first, curved edge section (11.1) that is concave on the inside of the groove (9), followed by a circular-arc-shaped edge section (11.2) that forms the rear end and again followed by a straight edge section (11.3) ending at the groove opening (10), in that the container carriers (6) on the container holders (8) are configured with at least two holding-down and/or support elements (14) which form the contact or support faces for that side of the container flanges (2.3) which faces the respective container mouth (2.1), and in that the at least two holding-down and/or support elements (14) are produced as a single piece with the respective container carrier (6), with the respective container holder (8) or the recess or groove (9) forming this container holder being at its edge (11) stepped in configuration, and in that the at least two holding-down and/or support elements (14) are provided at two opposite regions of the edge of the container holder (8) or of the recess or groove (9) forming this container holder.
  2. The transporter of claim 1 characterised in that the at least one hold-down and/or support element (14) forms a gap (15) with the opposite support surface (12) for an at least partial receiving of the respective container flange (2.3).
  3. The transporter of claim 3 characterised in that the gap (15) formed between the at least one hold-down and support element (14) and the support surface (12) is slightly greater, for example 0.2 mm greater, than the thickness of the container flange (2.3) received in this gap (15).
  4. The transporter of claim 1 characterised in that the at least two hold-down and support elements (14) of each container holder (8) are arranged on a notional connecting line (VL1) which is oriented square or substantially square to the transport direction (A) and which is preferentially offset in transport direction (A) relative to the closed end (11.2) of the respective recess or groove (9) by an amount greater than half the width which the recess or groove (9) comprises at its closed end, preferably by a factor ranging from 1.015 to 1.035, for example by a factor of around 1.03.
  5. The transporter of any one of the preceding claims characterised in that a notional connecting line (VL2) which connects the ends of the edge of the respective container holder (8) or of the recess or groove (9) encloses with the axis of transport direction (A) an acute angle which opens contrary to the transport direction.
  6. The transporter of any one of the preceding claims characterised in that each container holder (8) or each recess or groove (9) forming this container holder (9) is configured such that one end of the edge (11) of the container holder (8) or of the recess or groove (9) at the opening (10) of the container holder (8) is ahead of the other end of the edge (11) relative to the transport direction (A), and in that preferably at least one edge section (11.1) of the edge adjoining the one end is concavely curved.
  7. The transporter of any one of the preceding claims characterised in that the recesses or grooves (9) of the container holders (8) form lateral contact surfaces (13.1, 13.2) with their edge (11), and in that the recesses or grooves (9) comprise - in the region of these contact surfaces (13.1, 13.2) - dimensions which are preferably slightly larger, for example approx. 1 mm larger, than the outside diameter of the container flange (2.3) which can be received therein.
  8. The transporter of any one of the preceding claims characterised in that it is part of a container treatment installation (16), for example of an installation or device for the filling and sealing of the containers (2).
