Description
1 1 4- S (-- -7 Irrproved Fishbox The present invention is an improved f
ishbox.
Fishboxes are the open-topped, generally rectangular containers in which fresh fish are held during the time between their being caught and subsequently sold. Wdern f ishboxes are usually unitary structures mulded in a plastics reterial, especially HDPE, and are often designed so that several f ishboxes may be nested in one relative orientation but rmy be stacked by turning alternate 10 superinposed boxes through an angle of 180 degrees.
The contents of fishboxes are inevitably wet. In addition, during some at least of the tin-e in which the f ish are contained in the box, it is conrmn to preserve the f ish in a cool condition by packing them in ice. For exanple, the fish inay be stored in this way during their transit from the off -shore point at which they are caught to the eventual on- shore point of sale. Since the ice melts to a greater or lesser extent during that time, the nelt-water produced would remin in the fishboxes if provision were not made to drain the water from the boxes.
However, if the rrethod. used to drain the water is sinply to provide drain-holes in the base of each box, then water froal the upper boxes in a stack of f 11 led boxes drains through the lower boxes and becorres progressively more tainted as it drains.
It has therefore been proposed to construct fishboxes in such a way that liquid in each box is directed towards the ends and/or corners of the box and is there either encouraged to overflow down the outer face of each box or caused to flow downwardly through vertically aligned drain-holes in the stacked fishboxes. VWle such fishbox constructions do indeed divert melt-water from the box below, they are not wholly free of disadvantages. First of all, scine fish-boxes of this type do still allow some of the water from one box to enter the box below, at least in some conditions. Forthcoming regulations may require that fishboxes be so designed that this drainage from one box to another is not possible. Secondly, in fishboxes which have been designed to overcome these probleirs, the floor of the box has an upv)ardly-convex surface to drain the water to the ends and/or corners of the box; floors of this shape are liable to distort into a concave orientation under pressure of the contents of a full box, possibly reinforced by the weight of the fish in the box above. This distortion can occur even when the box floor is provided with a support rib on its underside. Modification of the floor cross-section to impart additional rigidity way require an irregular upper convex surface, which in turn can mark or damage the stored fish in contact with that surface.
One prior fishbox which has been devised to assist drainage of the meltwater from the centre of the box is described in UK Patent Specification No. 2104047. The fishbox therein described has a raised middle portion to the floor of the box, that is, it is generally convex as discussed above.
It is an object of the present invention to provide an improved fishbox wherein same at least of the disadvantages of prior fishboxes are reduced or eliminated.
The fishbox according to the present invention has the conventional unitary structure of a generally rectangular base and four walls upstanding frcm the base but it is is characterised in that the base slopes downwardly from its ends towards its longitudinally central region and further slopes downwardly from that central region towards a zone in the middle of the length of one or both of the longer sides of the base. Thus, in longitudinal cross-section, the base of the fishbox slopes downwardly towards the centre of the box but, in transverse cross-section in the region of the box centre, the fishbox slopes downwardly towards one or both of the box sides. Preferably the transverse cross-section is generally symmetrical such that the base is higher in the middle and slopes downwardly towards both sides.
It can be seen that the fishbox of the invention adopts the unexpected approach of draining its liquid contents f irstly to-yards the centre fram the ends of the box (unlike prior f ishboxes which drain the liquid from the centre towards the ends) and only then from the central region towards one or both of the box sides. In a preferred form of the box, the liquid is drained as aforesaid to the two sides of the box and is then drained along those sides towards the box ends in open channels extending along the sides of the base.
The fishbox according to the present invention has the very important merit that the base of the box is already generally concave from above and is therefore not subject to the possibility of distortion under the weight of the contents of the box, but still drains the liquid contents away from the centre of the box towards one or more positions at which they can be drained out of the f ishbox in any desired manner.
The various slopes of the base and channels referred to above may be plane or curved slopes and the lines of inter- section of the different slopes ray be rounded or angular. It is envisaged that the slopes will in any case be relatively shallow, for example not exceeding five degrees relative to the horizontal, and the lines of intersection will therefore not be acute. In the preferred embodiment described below and illustrated in the acconTpanyinq drawings, the inclination.
of the base towards the centre as seen in longitudinal cross-section is of the order of tvn degrees and the outward inclination in transverse section is only one degree. The inclination of the drainage channels along the sides of the base towards the ends is of the sane general order of about one degree only.
Although the base is inherently not liable to the distortion to wtdch upwardly-convex bases are liable, it may be given additional strength, if desired, by the provision of a transverse rib on the underside of the box in the region of the lateral drainag( slope.
The invention will now be further with reference to the accompanying drawings, which illustrate, by way of excunple only, one preferred embodiment of the improved fishbox according to the present invention and wherein:
Fig. 1 is a plan view of the box; Fig. 2 is a longitudinal sectional view along the line II-II of Fig. 1; Fig. 3 is a transverse sectional view along the line III-III of Fig. 1; and Fig. 4 is an elevation from one side of the box.
The illustrated fishbox is a one-piece product form,6d by injection noulding in plastics. It is in the form of a generally rectangular, open box having a base 10, end-walls 11 and 12 and side-walls 13 and 14. TAhile the central volume of the box, in which the fish are stored, is wholly symmetrical in longitudinal and transverse sectional view (Figs. 2 and 3 respectively), the external structure of the box differs between its tyn ends, as seen in Fig. 1. This difference, while permitting boxes to be nested when being transported empty, allows superinposed boxes to be stacked un-nested above each other when alternate boxes in a stack are t urn ed through 180 degrees about a vertical axis.
As shown in Figs. 2, the base 10 of the fishbox is inclined inwardly towards the centre of the length when viewed from the side. At that centre a shallow bracing rib 15 in-parts additional strength to the base. The inclination of the tQn halves of the box in this view is approxinately two degrees to the horizontal. Thus water draining through the box contents down to the base drains towards the centre of the length of the base. As shown in the transverse cross-sectional view of Fig. 3, at this central point the base tapers outwardly towards the sides of the box, at an inclination of the order of one degree to the horizontal. Thus water draining to the centre of the length of the box from its ends in turn drains outwardly towards the sides of the box.
Shallow longitudinal channels 16 and 17 extend along the sides of the base at the foot of the side walls 13 and 14 respectively. These channels in turn slope from the centre of their lengths down towards the ends of the box, the inclination of the channel halves being of the order of one degree relative to the horizontal. At the ends of the channels 16, 17 are drain holes 18 and 19. In the side view of the fishbox illustrated in Fig. 4, the interior slope of the box base 10 towards the centre fram its ends is hidden by the side wall 14, of which the external lower edge follows the slope of the channel 17 towards its ends.
Thus all surplus liquid draining to the base of the illustrated fishbox eventually flows out of the drain holes 18 and 19 in the base of the box. Below these drain holes the liquid is led by short inclined surfaces 20 and 21 respectively to overflow from the end walls away from the box, without draining or spilling on to lower boxes in a stack.

A fishbox having a unitary structure caffprising a generally rectangular base and four walls upstanding frcm the base, which base slopes downwardly from its ends towards its longitudinally central region and further slopes downwardly from that central region towards a zone in the middle of the length of one or both of the longer sides of the base.
