Definitions

• the present invention relates to an integrally moulded edge or corner protector for protecting edges of an object, said protector having at least two side-wall segments, each intended to abut against one of a number of edge surfaces forming a common edge, said side-wall segments together forming a wall section intended to be placed along the edge, each side-wall segment having mutually spaced rib-like pro ⁇ jections protruding from the outside surface of the wall segment, the latter comprising corresponding recesses in its internal surface as well as lower wall segments bordering upon said projections, projections protruding from the inside surface of the wall segment corresponding to said lower wall segments.
• Edge or corner protectors of the kind referred to above serve to absorb impact energy from impact directed against the edge regions of the object. They are especially suitable for use as a kind of cushion between the outside surface of the object, against which the edge or corner protector is to abut with its inside surface, and an external packaging means, e.g. in the form of a cover, against the inside surface of which the edge or corner protector is to abut with its outside surface.
• said wall section intended to be placed along said edge of the object is shaped with a recess facing the inside of the protector and having a limiting wall embracing the edge of the object at a distance from the latter, said recess being either in the form of a channel or gutter facing the edge and extending along practically the whole length of the edge being embraced, or in the form of a linear series of recesses extending along and facing the edge.
• Such pro ⁇ tectors are not always able to provide sufficient protection against impact directed directly against an edge region of the object.
• the object of the present invention to provide an edge or corner protector of the kind referred to above, that can provide a highly effective protection, also against impact against the edges of the object, including corner regions formed by converging edges.
• this object is achieved by a) that the wall section intended to be placed along the edge of the object comprises a continuous ridge, formed between the ends of projections and lower wall segments extending from the side-wall segments so as to meet each other, and b) that at their mutually facing ends, the recesses in the rib-like projections protruding from the outside surface of the wall segment are closed by means of an end wall, the free terminal edge of which terminates at the same level as and in continuation of the junction line between the ends of the bottom surfaces of bordering lower wall segments.
• the ridge referred to When placed against the object, the ridge referred to will be able to abut against the edge and provide a rigid protection means, both in the regions of the mutually facing ends of the rib-like projections and in the region of the junction line between the ends of the bottom parts of the adjoining lower wall segments.
• the bottom parts of the lower wall segments should preferably, according to the invention, be plane.
• edge or corner protector can, according to the invention, consist in that the lateral limiting walls of the rib-like projections and the bordering lower wall segments are of equal height. This implies that they are preferably in the form of common la ⁇ teral limiting walls.
• the cross-sectional shapes of the project ⁇ ions and the lower wall segments are substantially rectang- ular.
• a simple and hence advantageous embodiment can, according to the invention, consist in that the recesses in the rib-like projections protruding from the outside surface of each wall segment are closed by means of an end wall, the latter being common for two projections meeting each other.
• a corner protector with side-wall segments con ⁇ verging in a pyramid-like manner can according to the in ⁇ vention be characterized in that the rib-like projections are terminated at the apex of the pyramid in a common solid apical segment.
• an edge or corner protector shaped in the manner indicated above can according to the invention consist of a fibre-pulp material and be formed by aspirating a fibre pulp against a liquid-permeable mould, the moulding surface of which corresponds to the inside surface of the side-wall segments of the protector.
• this manufacturing method can, while utilizing the aspirating technology, advantageous- ly be used for producing e.g. said common end walls for the rib-like projections and the solid apical segments in a corner protector.
• Figure 1 is a diagrammatic perspective view of an embodiment of an edge protector, adapted to protect a straight edge of an object
• FIG. 2 at an enlarged scale shows a first detailed embodiment of the protector shown in Figure 1
• Figure 3 at an enlarged scale shows a second detailed embodiment of said protector
• Figure 4 shows diagrammatically an embodiment of a corner protector, said protector being placed on a corner of the object and itself embraced by an external packaging means
• Figure 5 is an external apical view of the corner protector of Figure 4, and
• Figure 6 is an internal apical view of said corner protector.
• the edge protector comprises two side walls generally designated 10 and 12, these side walls abutting against two edge surfaces A and B respectively of said object.
• the edge surfaces A and B intersect, forming the edge C of the object.
• the side walls 10 and 12 form a wall section, generally designated 14, intended to be placed along the edge C.
• Each side-wall segment 10 and 12 comprises mutually spaced rib-like projections 16 projecting outwards from the outside of the side walls.
• the rib-like projections 16 are shaped like inverted gutters or channels, recesses 18 on the inside of the wall segment corresponding to the rib ⁇ like projections 16.
• the side-wall segment comprises wall segments or recesses 20 bordering on and lower than the projections 16, projections 22 protruding from the inside of the wall segment corresponding to the recesses 20.
• edge protector shown serves as a protective insert between the object ABC and an enveloping wrapping, e.g. in the form of a cover, in which case the edge protector will abut a- gainst the outside of the object with its inwardly protruding projections 22, and the enveloping wrapping will be placed in abutment against the outwardly protruding projections 16 of the edge protector.
• the wall section 14, intended to be placed along the edge C of the object, comprises a continuous ridge 24, formed in part between the ends of projections 16,16, in part be ⁇ tween the ends of recesses 20,20, said projections and re- Cons extending from each side-wall segment 10 and 12 re ⁇ spectively to meet each other in the wall section 14.
• the reason for this is the fact, that the recesses 18 in the rib-like projections 16 protruding from the outside of each wall segment 10 and 12 at their ends facing each other in the wall section 14 are closed by means of an end wall 26, the free terminal edge 28 of which ends at the same level as and in continuation of the junction line 30 between the ends of the bottom surfaces 32 formed in the lower wall segments 20.
• the bottom surfaces 32 are plane.
• the project ⁇ ions 16 and the lower wall segments 20 have common lateral limiting walls 34, the projections 16 and the lower wall sections 20 having the same height. Further, in the embo ⁇ diment shown, the projections 16 and the lower wall segments 20 have a substantially rectangular cross-sectional shape.
• two mutually facing projections 16 in the region of the wall section 14 comprise an end wall 26, common to both projections 16.
• each projection 16 has its own end wall 28b, the two end walls 28b together forming an outwardly open angle, inwardly continuing in a common wall segment 28a.
• each projection 16 ends in an apex 38.
• the apex may have various contour shapes, and may e.g. also converge into a point.
• FIG. 4-6 The embodiment of a corner protector according to the invention shown in Figures 4-6 comprises three side- wall segments 10,11,12, intended to embrace the corner of the object ABC.
• the side-wall segments 10,11,12 converge in a pyramid-like manner.
• This embodiment is based on the same basic idea as the embodiment described above with reference to Figures 1-3, for which reason mutually analogous parts carry the same reference designations.
• the rib-like projections 16 converge in a common, solid apical segment 36.
• each of the projections 16 is terminated by a solid apex 38, projecting beyond the solid apical segment 36.
• an edge or corner protector that is shaped as described above, from a fibre- pulp material, and it may be formed in a manner known per se by aspirating a fibre pulp against a liquid-permeable mould, the moulding shape of which corresponds to the inside of the side-wall segments of the edge or corner protector.
• the finished-moulded product will already exhibit an inside surface, that corresponds fairly accurately to the outside surface of the object to be protected.
• the parts 16 and 20 will function as a cushion between the object ABC and an external packaging means 40, as shown in Figure 4.
• the continuous ridge 24 protects the edge C of the object, while at the same time protecting against impact directed against the edge of the object.
• the ridge 24 contributes towards protection against impact directed against a solid apical segment 36 constituting a part of an edge or corner protector.
