DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a packaging element in the form of an integrally moulded encasement piece in the form of a shell of pulp material produced through forming by suction a layer of a pulp suspension, whilst maintaining a draught angle on a porous mould for forming the piece, removal of the piece from the mould and subsequent drying of the piece to produce a finished element intended and designed to surround, embrace and support a free side region or end region of a mainly box-shaped article in an external shipping or presentation packaging.
BACKGROUND ART
Packaging elements of the kind referred to are used to surround and support free side regions or end regions of mainly box-shaped articles, and in the finished package they are embraced by an external shipping or presentation packaging element, e.g. in the form of a pre-fabricated case, box or envelope. Such a packaging element is known from WO 94/06704.
If the packaging elements are manufactured of a material such as expandable polystyrene, it is possible to finalize the elements almost without a draught angle, thus achieving practically full contact with the-article to one side and with the external packaging to the other side.
Within the conventional pulp-moulding method being used especially for manufacturing large numbers of packaging elements, it is required that a draught angle is maintained, at least during the moulding process so that the walls are clearing. A typical value of this angle lies in an order of magnitude of 8.degree.. This means that a packaging element of the kind set forth, manufactured by moulding a pulp material, will not come into full abutment, especially against the external, relatively thin shipping or presentation packaging.
BRIEF SUMMARY OF THE INVENTION
It is the object of the invention to provide a packaging element that is well-suited for manufacture using the conventional pulp-moulding method and having such a shape, that it is also possible to abut to the full extent against an external shipping or presentation packaging surrounding the package article.
According to the invention, this object is achieved by means of the construction of the packaging element as set forth hereafter.
The incisions make it possible to press said side-wall parts towards each other whilst narrowing the incision, which means that even the other side walls connected at an angle with these side-wall parts can be pressed inwardly in the shell whilst reducing or completely eliminating their angular position determined by the draught angle. This provides the prerequisite for a full abutment, both internally and externally.
An advantageous embodiment thereof of the invention has the width of the incision sufficient to compensate for twice the draught angle used during moulding.
Another advantageous embodiment, especially for use with long side walls, has two parallel incision.
The flexure axis in the base surface is preferably a flexure line, or a series of line segments.
Also preferably, at least two opposite side walls have inwardly facing portions for abutment against a side region or end region of the article and outwardly facing portions for abutment against the external shipping or presentation packaging which may be provided by using the conventional pulp-moulding method within the scope of the invention.
In a preferred embodiment, the outwardly facing portions are hollow, downwardly facing truncated pyramids having at least one freely protruding outer-wall surface, providing an advantageous embodiment for providing an external packaging abutment surface that can also be utilized as a guide surface for a packaging envelope.
Further, each pyramid makes it possible to provide useful supporting legs.
Disposing incisions in all side walls provides an embodiment for packaging elements of large dimensions, and stop knobs on the base surface of side walls provide measures for counteracting an inappropiately forceful pressing of the side walls against each other.
