Definitions

  • This invention relates to plastic bottles, in particular to a way of making plastic bottles more easily disposable and environmentally-friendly.
  • a problem associated with these known bottle designs is the number of fold lines that are to be found in the bottle design to enable it to adequately collapse.
  • the bottle design of the Duering patent requires that the bottle should have at least two long, vertical fold lines of the sides of the bottle, whilst the Supermatic bottle design has two long vertical fold lines along the sides of the bottle, and two horizontal fold lines which run around the whole of the bottle body. This leads to problems in that the bottle design may be undesirably weakened by the number of fold lines required, and hence requires the bottle to be made of a more rigid plastic than would otherwise be necessary.
  • a flexible walled container having a body portion with wall portions, a bottom portion which is substantially flat, enabling the container to stand upright, a top portion with a neck to which sealable closure means such as a closure cap may be attached, and a single fold line consisting of an indentation of a surface of a wall portion which transversely crosses the container, and runs substantially parallel to the bottom portion of the bottle, enabling the base of the container to be folded upwards and the body portion generally flattened.
  • the fold line is only on one wall portion of the container, with that section of the container being wider than, or equal in breadth to any other wall portion of the container.
  • the fold line is located substantially towards the bottom portion of the container on a wall portion, horizontally (with regard to the bottom portion), and at a distance from the bottom of around half the maximum width of the bottom portion. In practice this is often within about 2 centimetres of where the wall portion meets the bottom portion.
  • the container according to the invention may conveniently be made from plastics materials, for example by blow-moulding techniques.
  • the container has a substantially oval cross section.
  • Figure 1 shows a front view of a bottle according to the invention.
  • Figure 2 shows a bottom view of a bottle according to the invention.
  • Figure 3 shows a side view of a bottle according to the invention.
  • Figure 1 shows a bottle having a body portion 1, which is made up of two wall portions, a front wall (not shown) and a back wall 2.
  • the bottle is substantially oval in cross section (as shown by figure 2), and therefore does not have discernable side walls.
  • Body portion 1 has a bottom portion 3 which is substantially flat, and which allows the bottle to stand upright.
  • Body portion 1 also has a top portion 4 having sloping shoulders 5, and a conventional neck 6 to which a closure cap (not shown) may be attached, for example by means of a screw thread 7.
  • Neck 6 also has an orifice (not shown) through which fluid contained in the bottle may be dosed and dispensed.
  • a single fold line 8 Located towards the bottom portion 3 of the bottle is a single fold line 8.
  • the bottle has only one fold line, located in this embodiment on the back wall of the bottle, although it could equally well be located on the front wall.
  • the single fold line 8 is located between recess fold lines 9, which are moulded into the bottle. Recess fold lines 9 facilitate the folding flat of the bottom portion 3 of the bottle, such that bottom portion 3 may be substantially parallel to back wall 2 after folding.
  • Figure 3 shows a side view of the bottle, in particular the relation of recess folds 9 and fold line 8.
