Definitions

  • the invention relates to a foldable plastic bottle according to the preamble of claim 1.
  • Foldable plastic bottles of the type mentioned at the outset are known several times, for example from EP-0 408 929 A2.
  • This bottle is made of thin-walled plastic and is made using the blowing process. So that it can be easily folded by hand when empty, the bottom part contains an inward-facing V-shaped indentation with a bottom folding edge.
  • the cross-section of the bottle body is hexagonal, each of which contains an outer folded edge at an obtuse angle to each other and outwardly projecting side surfaces.
  • the bottom folding edge and the jacket folding edges lie in the same longitudinal center plane of the bottle.
  • the disadvantage here is that the bottle requires a complicated base formation and a special cross-sectional shape in order to be foldable.
  • the foldable bottle does not remain in the best possible folded condition, but the screw cap must be applied to prevent ambient air from being sucked in and thus prevent the bottle from expanding.
  • all sides of the bottle are provided with folded edges, so that there are difficulties and narrow limits with regard to the labeling and decoration of the bottle.
  • DE 40 01 429 A1 also describes a collapsible bottle of the type mentioned at the outset.
  • This bottle also requires a special bottle body with a hexagonal cross section, with inner edges and essentially sharp foldable outer edges.
  • the bottom is drawn in to form outer bottom edges and has a foldable center line which extends longitudinally between the ends of the outer edges.
  • the bottom edges have four outer, rising bevels that converge to the ends of the outer edges.
  • This foldable bottle is also of relatively complicated construction and requires a special design, so that the bottle shape cannot be freely selected. It is also difficult to label and decorate such a bottle.
  • the object of the invention is to design a foldable bottle of the type mentioned at the outset in such a way that it not only has a relatively simple structure, but also allows the bottle to be largely freely designed and is easy to label and decorate.
  • the object is achieved according to the invention by the characterizing features of claim 1.
  • the fold lines provided according to the invention are not tied to any special shape of the bottle, so that many arbitrary bottle shapes in the oval / round area can be made foldable with the arrangement of the fold lines according to the invention.
  • the arrangement of the fold lines is extremely simple and is only required on one side of the bottle, so that the other side of the bottle has the appearance of a normal bottle.
  • This other bottle side, which is not provided with fold lines, also allows free decoration and labeling in the frame previously known for non-foldable bottles.
  • the configuration according to the invention can easily allow the bottle to be folded permanently, and specifically when the bottle parts are countered by a kind of pretensioning action, which can be caused in particular by the fact that one side of the bottle is not provided with fold lines and forms a more rigid shell the stiffer shell to be pressed.
  • the bottom part also ensures a secure stand, since, in contrast to the known foldable bottles, it has no fold lines.
  • an embodiment according to claim 2 is very expedient and improves the folding properties, in particular of thicker folding bottles.
  • the third fold line arranged above the bottom part can only extend up to the first fold lines.
  • Claim 4 describes a particularly advantageous embodiment for folding the bottom against the body.
  • the first and second fold lines can run at least approximately to the third fold line or optionally also open into the latter.
  • first fold lines end at the top of the bottle body.
  • a fourth fold line which likewise runs upward in an arc-like manner.
  • the bottle according to the invention can in particular be designed as a light and medium-weight bottle. It is suitable for a wide variety of products and can be used both as a mother bottle and as a refill bottle.
  • the bottle geometry can be selected within wide limits, the cross section of the bottle body in particular being able to assume any shape from flat to polygonal to round.
  • the bottle shown in Figures 1 a to 1e has a bottle body K1, which has a bottom part B1 at the bottom and a neck part H1 at the upper end, which merges into a pouring part A1, which is provided with a closure part V1.
  • the bottle body K1 has an essentially flat, oval cross section, as can be seen in particular from FIGS. 1 and 1e.
  • the bottle has first fold lines F1a along the main central plane M1, at least in the area of the bottle body K1, which extend from the base part B1 to the neck part H1.
  • the first fold lines F1a are assigned on one side 1a of the bottle body K1 second fold lines F2a, which run essentially parallel to the first fold lines F1a.
  • the distance between the second fold lines F2a and the first fold lines F1a is approximately 1/8 to 1/12 of the circumference of the bottle body K1 in the circumferential direction.
  • the bottle is also provided with a third fold line F3a, which runs on the first side 1a of the bottle body in an arc-like manner up to flat above the base part B1, the mean distance D1 of the third fold line F3a from the base surface 3 being approximately the same size is like the radial distance R1 from the main median plane M1.
  • the third fold line F3a preferably extends somewhat beyond the main median plane M1 into the second bottle side 2a.
  • the first fold lines F1a and the second fold lines F2a extend directly to the third fold line F3a or open into it.
  • the fold lines are formed by beads 4 which are directed against the inside of the bottle.
  • FIGS. 1d and 1e show the bottle in the folded state, the first bottle side 1a being pressed against the second bottle side 2a.
  • the areas between the first fold lines F1a and the second fold lines F2a lie on the inside of the second bottle side 2a, while the area between the second fold lines F2a is bulging and protrudes, whereby the adjoining sections bear against the inside of the second bottle side under tension.
  • the bottom part B1 is folded in, as can be seen from FIG. 1d. Because of the pre-stressing described, the folded bottle essentially retains its folded shape.
  • FIGS. 2a to 2e show a further foldable bottle with a base part B2, a bottle body K2 with an oval cross section, a neck part H2 and a pouring part A2.
  • the latter has a larger cross section than the configuration of the bottle according to FIGS. 1a to 1e and is provided with a corresponding closure part V2.
  • the design of the bottle according to FIGS. 2a to 2e corresponds to the bottle according to FIGS. 1a to 1e.
  • the bottle contains first fold lines F1 b running along the main central plane M2, to which second fold lines F2b are in turn assigned on the first bottle side 1 b and run parallel to the first fold lines F1 b.
  • the first fold lines F1 b and the second fold lines F2b extend to a third fold line F3b above the bottom part B2.
  • the third fold line F3b again runs arc-like to flat between the first fold lines F1 b and ends on the second bottle side 2b.
  • the distance D2 of the third fold line F3b from the bottom surface 3 is approximately equal to the radial distance R2 from the main center plane M2.
  • the folded state of the bottle according to Figures 2d and 2e corresponds to that of the first embodiment of Figures 1d and 1e.
  • Figures 3a to 3e describe a third foldable bottle, which in turn is formed from a bottom part B3, a bottle body K3, a neck part H3 and a pouring part A3, which is closed by a closure part V3.
  • the bottle body K3 has a circular cross section. Due to the circular cross-section there is no pronounced, but only an assumed main central plane M3, according to which the fold lines are aligned.
  • This bottle also has first fold lines F1c running along the main center plane M3, to which second fold lines F2c running parallel are assigned on the first bottle side 1c.
  • the base part B3 there is an arcuate third fold line F3c, the distance D3 of which in the central region from the base surface 3 in turn corresponds to the radial distance R3 from the main central plane M3.
  • the first fold lines F1c and the second fold lines F2c again extend directly to or open into the third fold line F3c.
  • the first fold lines F1c are connected to one another by a fourth fold line F4, which likewise runs in an arc-like manner to flat and is arranged in the neck part H3.
  • the folded state of the bottle according to Figures 2d and 2e corresponds to that of the first embodiment of Figures 1d and 1e.
  • FIGS. 4a to 4e show a third embodiment of a foldable bottle, consisting of a base part B4, a bottle body K4, a neck part H4 and a pouring part A4, which in turn is provided with a closure part V4.
  • the closure part is designed as a spray head with a hand-operated pump.
  • the bottle body K4 again has an oval cross section and is along the main means
  • Level M4 is provided with first fold lines F1d, to which second fold lines F2d are assigned on the first bottle side 1d and which run parallel to the first fold lines.
  • the first fold lines F1d and the second fold lines F2d extend up to the neck part 4 and end at the lower end in or in front of a third fold line F3d which is arranged above the bottom part B4.
  • the third fold line F3d again runs in an arc-like manner between the two first fold lines F1d on the first bottle side 1d.
  • the ends of the third fold line F3d extend beyond the main median plane M4 into the second bottle side 2d (as can be seen in particular from FIG. 4b).
  • the distance D4 of the central area of the third fold line F3d from the base surface 3 in turn corresponds to the radial distance R4 of this area from the main central plane M4.
  • the folded state of the bottle according to Figures 2d and 2e corresponds to that of the first embodiment of Figures 1 d and 1e.
