Abstract
The plastics material device has a plurality of generally quadrilateral openings for receiving and gripping the containers. The openings have their sides formed by strips and each of the strips of two opposite, corresponding sides of each opening are orientated along their length, the strips of the remaining two opposite sides not being substantially orientated. The strips, at least, have substantial elasticity.
Claims14
A device for holding a plurality of containers together, comprising an integral piece of plastics material which has a plurality of generally quadrilateral openings for receiving and gripping respective containers, each opening having its sides defined by a pair of mutually spaced first strips and a pair of mutually spaced second strips generally at right angles to the first strips, each first strip being orientated in the direction of its length and having substantial elasticity and the second strips not being substantially orientated, and the first strips of one opening being aligned with the first strips of an adjacent opening with the orientation passing from an end of each first strip into the adjacent end of an aligned first strip.
A band providing an integral succession of devices each for holding a plurality of containers together, the band comprising an integral, elongate piece of plastics material which has generally quadrilateral openings spaced along its length, for receiving and gripping respective containers, each said opening having its sides defined by a pair of mutually spaced longitudinal strips and a pair of mutually spaced transverse strips, respective longitudinal strips being aligned along the length of the band and the longitudinal strips being orientated in the direction of their length and having substantial elasticity, and the transverse strips not being substantially orientated, the orientation passing from an end of each longitudinal strip into the adjacent end of an aligned longitudinal strip.
A method of making a device for holding a plurality of containers together, comprising forming a plurality of long-shaped holes or depressions on a notional rectangular grid in plastics sheet material which when orientated has substantial elasticity, and then stretching the material only at right angles to the major axes of the holes or depressions, to orientate, and draw into strips, zones at the sides of the holes or depressions and to form the holes or depressions into openings for receiving and gripping the containers, the stretching being continued until the orientation of each said strip passes from an end thereof into the adjacent end of an aligned said strip.
A pack comprising at least two containers and at least one device holding the containers together, the device comprising an integral piece of plastics material which has a plurality of originally generally quadrilateral openings receiving and gripping the respective containers, each opening having its sides defined by a pair of mutually spaced first strips under tension, and a pair of mutually spaced second strips under tension, originally generally at right angles to the first strips, the first strips being twisted so that the centre part of each first strip lies flat against the side of the respective container and the first strips being orientated in the direction of their length and having substantial elasticity while the second strips are not substantially orientated.
A method of packing containers, comprising:
- providing a band comprising an integral succession of devices each for holding a plurality of containers together, the band comprising an integral, elongate piece of plastics material which has generally quadrilateral openings spaced along its length, for receiving and gripping respective containers, each opening having its sides defined by a pair of mutually spaced longitudinal strips and a pair of mutually spaced transverse strips, respective longitudinal strips being aligned along the length of the band and the longitudinal strips being orientated in the direction of their length and having substantial elasticity, and the transverse strips not being substantially orientated;
- inserting containers in the respective openings whereby the containers are gripped by the sides of the openings;
- and subsequently separating the groups of containers by dividing the band between the groups.
