[0001] This invention relates to an arrangement for temporarily immobilizing the internal
accessories of domestic cooking appliances, such as cookers, ovens and the like, such
immobilization being temporarily required during the handling of the appliances.
[0002] Both electrically and gas operated domestic cooking appliances comprise a series
of accessories which are placed in the cooking compartment of the appliance after
being grouped together into a flat bundle which is covered with thermo-shrinkable
material and then with protective materials (such as foamed plastics or air-chamber
plastics) to form a protected pack, self-adhesive tape then being used to close the
pack and to fix it to the walls of the cooking compartment (ie immobilize it).
[0003] The reason for this is that during the various handling operations to which the appliance
is subjected before reaching the user, any accessories (grids, spits, shelves and
guides) not immobilized could move and be damaged, or cause damage to the walls of
the compartment housing them, and in particular to the glass door which closes the
access to the compartment.
[0004] This known method has a series of drawbacks, including the evident time and material
wasted in forming the pack and fixing it inside the compartment, the use of relatively
costly materials, a certain disorder on unpacking the accessories, and finally an
insufficient guarantee against damage occuring should the adhesive tape which fixes
the pack to the compartment walls become detached, as not infrequently happens.
[0005] The main object of the present invention is to provide a protective arrangement for
temporarily immobilizing the accessories placed inside domestic cooking appliances,
the arrangement resulting in a series of substantial advantages over the know art,
including: a) being formed in its essential protective part by a single material rather
than by several materials of different type; b) being able to be used on different
appliance models; c) requiring very little storage and transport space; d) requiring
only little material; e) being of simple and immediate application; f) allowing instructions
or information to be applied; g) providing reliable and effective protection both
to the accessories and to the compartment containing them.
[0006] This and further objects which will be more apparent from the ensuing detailed description
are attained by the arrangement according to the invention, which is characterised
essentially by comprising a paper-material structure comprising a base and surrounding
flaps joined to said base so as to be able to be raised to form mutually counteracting
side walls bounding said base, at least one of said flaps comprising a longitudinal
elongate aperture.
[0007] The invention will be more apparent from the detailed description of two preferred
embodiments thereof given hereinafter by way of non-limiting example and illustrated
on the accompanying drawing, in which:
Figure 1 is a perspective view of a first embodiment of the structure involved in
the arrangement;
Figure 1A is a schematic top view of the structure of Figure 1 according to the present
invention, with its flaps erect;
Figure 2 is a perspective view showing the initial stage of insertion of the structure
of Figure 1 into the compartment of a domestic electric oven;
Figure 3 is a perspective view showing the insertion of the internal oven accessories
into the structure;

the compartment and with other accessories positioned in said structure;

the oven version of Figure 4;
Figure 6 shows the structure within the compartment with the apertured front closure
flap raised;

accessories content can be checked even with the structure present;
Figure 8 shows a different embodiment of the structure suitable for domestic cooking
appliances with only a small number of internal accessories.
[0008] With reference to Figures 1-7, the structure constituting the essential part of the
arrangement for immobilizing the internal accessories of a domestic cooking appliance
provided with a compartment in which said accessories can be housed during the handling
of the appliance is indicated by 1, it being constructed of paper material of good
rigidity such as corrugated cardboard, and comprising a rectangular or square base
2, to each side of which a flap indicated respectively by 4, 5, 5A, 6 and 7 is joined
via creasing lines 3.
[0009] It should be noted that the width "K" of the flap 7 across the outside of the undercuts
8 is greater than the width of the corresponding side 3 of the base 2. The same applies
to the two adjacent half-flaps 5 and 5A on the opposite side of the base 2, due to
the fact that undercuts 9 are also used here.
[0010] The two remaining flaps (ie 4 and 6) have a width equal to the width of the side
3 to which they are joined. Because of this dimensioning, when the flaps are erect
and the structure is assembled in situ, ie in the compartment which is to receive
the appliance accessories, the flaps 4 and 6 become interposed between the other flaps
(7, 5, 5A), as shown schematically in Figure 1A in which the structure is shown in
plan view with the flaps erect at 90° to the base 2, the resultant counteraction points
between adjacent flaps being indicated by P, Q, R and S.
[0011] The flap 4 has a height Z greater than the opposite flap 6 and comprises at least
one pair of creasing lines 10, 11 parallel to the corresponding creasing line 3 to
enable this flap, with its parts divided in this manner, to assume different angles
as shown for example in Figure 4.
[0012] The flaps 5 and 5A divide the same side 3 of the base 2, the flap 5 comprising at
least one pair of creasing lines 12, 13 parallel to the side 3 to enable those regions
into which said creasing lines divide the flap to assume different angles.
[0013] The flap 6 comprises an aperture parallel to the corresponding side 3 of the base
2, on one side of this aperture there being a tab 15 foldable about a creasing line
16.
[0014] The fourth and last flap, ie that indicated by 7, comprises a large aperture 17,
from the lower edge 18 of which there extends a tab 19 extending along only a fraction
of said edge and joined to the flap 7 via a creasing line.
[0015] The tab 19 also comprises at least one pair of creasing lines 20, 21 parallel to
the edge 18 to enable the regions of this tab to assume different inclinations.
[0016] The dimensions and shape of the flap 17 are suitably chosen so that it fits tightly
into the mouth of the compartment V of the appliance A in which the relative accessories
are placed after the structure 1 has been inserted into the compartment.
[0017] The dimensions of the base 2 are chosen to correspond to the cross-section of the
compartment.
[0018] The structure 1 is inserted into the compartment V (Figure 2) so that the half-flaps
5, 5A rest against the inner end wall D of the compartment V, with the base 2 resting
on the lower wall of the compartment. If the side walls of the compartment V comprise
non-removable projecting guides 30 for the grids or shelves forming part of the appliance
accessories, the side flap 6 is mounted over these guides via the aperture 14 provided
in it. The tab 15 then remains bent at an angle towards the compartment V. If instead
of fixed guides the compartment V comprises removable guides 40 which when removed
also form part of the internal accessories, the flap 6 simply rests against the wall
of the compartment V as shown in Figure 4, in which these guides are shown contained
within the structure 1 and retained by the folded half-flap 5 on one side and by the
folded tab 19.
[0019] In either case the pack W in the form of a thermo-shrinkable plastics envelope containing
the other accessories is now inserted (see Figures 3 and 5) to assume an inclined
position. At this point a piece of self-adhesive tape 31 is applied between the flap
4 and the pack W (then raising the tab 19 in the case of the fixed guides so as to
in both cases achieve the configuration of Figure 5). Finally the correspondingly
shaped and dimensioned flap 7 is lightly forced into the mouth of the compartment
V, and the door Q of the compartment is closed so that it possibly rests against the
flap 7 (by suitably dimensioning the structure 1. The door Q comprises a conventional
window F through which the accessories contained in the compartment V can be checked,
the aperture 17 in the flap 7 being positioned to at least partly coincide with the
transparent glass of the door window as shown in Figure 7.
[0020] The embodiment shown in Figure 8, in which equal or corresponding parts carry the
same reference numerals plus 100, comprises on opposing sides two flaps 104 and 106
both identical to the previously described flap 6. The two remaining sides 105 and
107 are identical to each other, with their equal widths K being greater than the
width of the side to which they are joined, in order to achieve the counteracting
effect visible in Figure 1A.
