Definitions

  • the invention relates to a bottle tray according to the preamble of claim 1.
  • a bottle tray of the above-mentioned type is known from NL-B-1004725.
  • the dimensions of the cavities and the cap spaces of the tray are equal to or only slightly larger than those of a base of a bottle accommodated therein or of a cap placed on the bottle. This means that a stable stack of trays with bottles placed in them can be formed, which is advantageous for the transportation of such stacks.
  • caps carelessly on the bottles for example if not down as far as possible or slightly askew and/or if the sealing strips are not torn off completely
  • such carelessly replaced caps and caps with sealing strips partially hanging off in a stack of trays with bottles can become stuck in the cap spaces and flange spaces.
  • bottles with such caps are substantially filled, their weight generally ensures that during the unstacking a bottle with a cap stuck in a cap space of a tray above is not lifted up along with it when the tray above is lifted.
  • bottles are empty plastic bottles, such as empty PET bottles
  • their weight is so low that such an empty bottle with a cap stuck in a cap space or flange space of a tray above is lifted up along with a tray above when the tray above is lifted.
  • This is very annoying when unstacking is being carried out manually, and it takes time to eliminate the problem. It is even more annoying, time-consuming and expensive to eliminate such a fault when the aim is to unload many stacks quickly and automatically from a vehicle and unstack them, for example in a bottling plant.
  • the object of the invention is to overcome the above-mentioned drawbacks of the known bottle tray.
  • the invention provides a bottle tray according to claim 1.
  • the result is that a partially torn-off sealing strip is largely prevented from becoming stuck between the flange of the corresponding bottle and the vertical wall of the flange space.
  • the number of disruptions during automatic processing of stacks of trays with empty bottles can be very greatly reduced.
  • Fig. 1 shows in perspective a part of the underside of a bottle tray 1.
  • the part of the tray 1 illustrated has on the underside a flange space 5, which at a higher level passes into a cap space 6, which has a smaller diameter than the flange space 5, and above which a cavity 7 is situated.
  • passages 8 are formed for the drainage of washing water or other liquids.
  • the embodiment of the tray 1 shown is suitable in particular for placing the base of a bottle 9 in the cavity 7 with little or no play, and for placing a cap 10, screwed onto the bottle 9, in the cap space with little or no play, in such a way that a horizontal upper wall 14 of the flange space 5 rests on a flange 11 of the bottle 9 formed below the cap 10, and the flange 11 of the cap 10 is centred by a side wall 16 of the flange space.
  • the cap 10 has on its underside a sealing strip 17, which is suitable for being torn off at least partially from the remainder of the cap 10 along a tear line 18, so that the cap 10 can subsequently be removed from the bottle 9.
  • the flange space 5 On the underside, along the periphery, the flange space 5 has radial recesses 20 with side walls 21.
  • the distance between the walls 21 of the recesses 20 and the centre 23 of the flange space 5 is equal to or greater than half the diameter of the flange 11 plus the thickness of the sealing strip 17.
  • the recesses 20 form a space for accommodating without clamping action a partially torn-off sealing strip 17.
  • a number of bevelled struts 26 are preferably formed against the vertical wall 21.
  • the distance between the struts 26 and the centre point 23 decreases closer to the cap space 6, in particular to a distance that is equal to the distance between the wall 16 of the flange space 5 and the centre point 23.
  • the struts 26 prevent the part of the bottom 14 of the recesses 20 of a tray from resting on a cap 10 of a bottle 9 below, and consequently resulting in faulty stacking.
  • the struts 26 centre the cap 10 during the stacking, and prevent such faulty stacking.
  • the bottle tray has to be manufactured by means of injection moulding, it is desirable at the design stage to ensure that the material cools down as uniformly as possible over the entire tray, in order to prevent the occurrence of stresses in the material, and consequently deformation of the tray, in particular if the tray is removed from an injection mould prior to complete cooling. For that reason, it is desirable to use the same wall thicknesses over the entire tray, and for the cap space 6 not to be bounded by a single, relatively thick cylindrical wall, but by a ring of evenly distributed vertical ribs 27, which describe a geometrical inner diameter of the cap 10.
  • the bottom part of the cap space 6 is bounded by a closed wall 28 instead of by bottom parts of the ribs 27.
  • the diameter of the cap space 6 within the wall 28 is preferably equal to or greater than the diameter of the cap 10 plus the thickness of the sealing strip 17. This further reduces the risk of the cap 10 becoming stuck.
  • the bottom wall 28 of the cap space 6 preferably has a height of between 30% and 60% of the distance between the flange 11 of the bottle 9 and the top side of the cap 10.
  • the transition 40 from the upper wall 14 of the recesses 20 to the higher wall 28 of the cap space 6 is more pronounced, in other words is rounded with a greater radius of curvature than that of other cavities 7.
  • a resulting adverse effect of reduced support of bottles below the cavities 35 is compensated for by the advantage of better stacking.
  • the number of recesses 20 can, for example, be different and can be dependent upon materials used for bottle caps 10 and tear-off properties of the sealing strips 17.
