Definitions

  • This invention relates to corner joints for forming right angles between pairs of panels and is particularly although not exclusively applicable to corner joints for forming right angles between adjacent side walls of a box formed from a blank sheet or sheets.
  • U.K. Patent Specification No. 1532317 discloses a joint made of a synthetic plastics material and fitted to a top corner of a cardboard box of rectangular or square chape so that the box may be rendered packable, the joint comprising two mutually perpendicular lateral faces adapted to be placed against the outside of the box, a bearing surface at right angles to the inter-section of the lateral faces for receiving a bottom corner of a corresponding overlying box and a plurality of clamping plates arranged on the inside below the bearing surface spaced from the lateral faces and perpendicular to the bearing surface, with the aid of which the joint may be clamped on to the upright box walls.
  • a corner joint has also been proposed in which a base has two mutually perpendicular walls to lie against the inner sides of a corner of a box and two resilient tongues on the outer sides of the walls to engage the outer sides of the corner and hold the walls of the joint against the corner. With that arrangement however it is difficult to separate the tongues from the walls to assemble the joint on the corner.
  • This invention provides a corner joint for forming a right angle between a pair of panels of a container comprising a base having two edges extending at right angles to each other to form the base with a right angled apex, two dependent walls extending downwardly from the base adjacent to said two edges of the base respectively for engaging the outer sides of a pair of panels of a container and two resilient tongues depending from the base at locations based inwardly of said two edges of the base respectively to engage the inner sides of the pair of panels of the container, the tongues being accessible from the outer sides of the walls to he-pressed manually away from the walls for assembly of the corner joint on a pair of panels of a container and, on release, to engage and hold the panels against said walls.
  • the invention also provides a corner joint for forming a right angle between a pair of panels comprising a base having two edges extending at light angles to each other to form the base with a right angled apex, two walls depending from the base at right angles to each other and aligned with the right angled edges of the base, two resilient tongues depending from the base each tongue being located to one side of a respective wall for holding a pair of panels engaged with the two walls, each of which tongues has a projection formed thereon partway down the tongue on the side adjacent a respective wall to engage in a corresponding hole in the respective .panel to be engaged by the tongue, each of which pips is formed with an inclined ramp face on the side nearest the bottom end of the tongue to assist in guiding the upper edge of a respective panel over the projection as the joint is located on a panel.
  • the resilient tongues are inclined with respect to the base towards the respective walls or the planes in which said walls lie such that, in their relaxed condition, the lower ends of-the tongues are closely adjacent the walls or said planes.
  • Simple open topped boxes which are required to be filled and then packed one on top of each other are frequently supplied in a very large number in flat condition and are intended to be assembled as and when required.
  • boxes for food and in particular fruit and vegetables are frequently used in this manner.
  • a simple form of box of this type comprises a cardboard blank having a rectangular base and four side walls which are folded up along lines which may be pre-creased.and locked together when the box is required for use.
  • the box may be formed in hardboard in which the flat blank comprises a base with the four side walls hinged to the edges of the base. This invention is particularly concerned with a corner joint for locking two adjacent side walls of the box together and for permitting one box to be stacked on another.
  • Figures 1 and 2 of the drawings show two side panels 10, 11 of a cardboard or hardboard box which have been folded up from a base as previously described to form a right angle between them and are held together by a corner joint indicated at 12.
  • the corner joint which is illustrated in greater detail in Figures 4 to 6, comprise a base 13 having two side edges 14, 15 extending at right angles to each other.
  • Two integral walls 16, 17 lying at right angles to each other depend from the lower face of the base. The upper ends of the walls lie along but are spaced slightly inwardly of the sides 14, 15 of the base.
  • Each wall 16, 17 has a large , aperture 18, 19 therein so that the walls are generally U -shaped with two adjacent limbs 16&,17a, of the U forming an integral apex and two limbs 16b, 17b spaced from the apex.
  • the upper corner portions of the panels 10,11 lie adjacent the inner sides of the walls 16, 17 and the panels are held against the walls by resilient tongues 20, 21 depending from the base 13 adjacent the inner sides of the walls opposite the apertures 18, 19 therein.
  • the resilient tongues are inclined towards the walls l6, 17 so that the free ends of the tongues lie adjacent the apertures in the walls 16, 17.
  • the free ends of the tongues may lie just short of the apertures or in the apertures or may even project slightly through the apertures.
  • Each tongue has a raised projection 22, 23 on the side thereof adjacent the respective side wall 16, 17 to engage in a hole 24, 25 formed in the respective panel 10, 11 to assist in holding the joint on the panels of .the box.
  • the lower side of each projection 22, 23 is formed with a chamber 22a, 23a, to provide a ramp for guiding the upper edge of the respective panel 10, 11 outwardly past the projection as the corner joint is pressed into the panels.
  • Also downwardly extending lugs 26, 27 are formed between the base and the inner sides of the limbs 16b, 17b. The lower ends of the lugs 26, 27 have chamfers formed thereon.
  • the upper edges of the panels 10, 11 are formed with notches 28, 29 in which the lugs engage to assist in locking the panels 10, 11 into the corner joint and prevent them from moving outwardly of the apex of the joint.
  • the joint can conveniently be assembled on a corner of a box or container by holding the joint between the thumb, in the recess 13 or in the base 13 and two fingers extending the apertures 18, 19 and bearing on the resilient tongues 20, 21.
  • pressure is applied to the resilient tongues by the fingers to deflect the tongues inwardly sufficiently to enable the container panels to be received between the tongues 20, 21 and the walls 16, 17 of the joint.
  • the joint is then pressed downwardly until the base 13 engages the top edges of the container panels as shown in Figures 1 and 2.
  • the projections 22, 23 snap into the apertures 24, 25 in the container panels automatically on reaching the apertures and the lugs 26, 27 engage in the notches 28, 29 in the top edges of the panels.
  • the base 13 at each corner of the box is intended to receive the bottom corner of a further box to be stacked on top.
  • the base is formed with an up-standing flange 30 along the sides 14, of the base. Depending on the strength of the material used for the boxes and the weight of goods contained therein, a number of such boxes can be stacked one upon the other.
  • FIG. 7 of the accompanying drawings shows a joint generally similar to the joint described and illustrated above and like parts have been allotted the same reference numerals.
  • the integral walls 16, 17 are further extended downardly as indicated at 16a and 17a and are formed with further cut-outs 32, 33 to reduce the amount of material required for the extension.
  • the length of the downwardly extending integral walls from the base to the bottom edge 34 of the walls is equivalent to the depth of the container on which the joint is to be used so that when the joint is assembled on the container, the bottom edge 34 lies generally flush with the bottom face of the container.
  • Figures 8 and 9 show an alternative construction in which the side walls 16, 17 are somewhat narrower and are reinforced by a rib 14 extending down the outer apex between the two walls from the base and tapering to nothing at the bottom edges of the walls.
  • the resilient tongues 20, 21 are spaced to one side of the walls 16, 17 and located inwardly of the walls to provide access to the tongues to deflect the tongues inwardly when assembling the joint on a corner of a container as previously described.
  • the joint has two further downwardly extending walls 36 which are located on the opposite sides of the tongues to the first walls 16, 17 and are spaced still further inwardly of the side edges of the base 13 than the tongues 20 and walls 16, 17.
  • the lower ends of the walls 36, 37 merge together in a downwardly extending angle section leg 38 which is spaced generally inwardly of the walls 16, 17 as best seen in the underplan view of Figure 9.
  • the leg 38 is intended to lie down the inner side of the corner between the two panels on the container to which the joint is to be attached and the length of the leg 38 is such that the bottom face of the leg bears on the bottom of the container.
  • the weight of one container is transmitted through the legs of the corner joints of the container to the corner joints of the container below so that the weight of the stack is taken through the corner joints.
  • the resilient tongues may be provided with pips to engage holes in the panels of the container as previously described and, likewise, lugs may be provided on the underside of the base adjacent the walls 16, 17 to engage notches in the upper edges of the panels of the container again as previously described.
  • corner joints described above are conveniently manufactured as one-piece injection mouldings from a hard plastics such as polypropylene or nylon. It will be appreciated that many modifications may be made to the above described embodiment without departing from the scope of the invention.
  • the projections 22, 23 on the resilient tongues may be omitted along with the holes in the panels of the box not then required as may be the lugs 26, 27-on the base and the corresponding notches in the panels of the box.
