[0001] The present invention relates to a packaging for the transport of domestic gas stoves
or top cookers where the top burners are individually housed in particular box inside
the general packaging for the appliance.
Prior Art
[0002] For the transport of gas stoves or top cookers when the burner heads are not secured
to the appliance, packaging is known which includes two U-shaped polystyrene foam
corner beads completely surrounding the cooker to protect it from impacts, covered
entirely by a thermoshrinkable elastic sheet that fits to the surface shapes. Said
U-shaped corner beads leave a square opening in the centre of the cooker where the
burners are placed in their housings on the cooker tray and are secured to it with
adhesive tape. This known packaging has the drawback that the burners are of considerable
weight and the adhesive tape does not always withstand their movement during transport,
so that some come loose and strike the enamel on the working cooker tray. The adhesives
also leave cement on the burner which is difficult to remove merely by rubbing.
[0003] Another known package incorporates four corner beads to protect the cooker, each
with a cylindrical housing for a burner which is subsequently covered with the thermoshrinkable
sheet which wraps it completely. This is a costly solution, requiring a different
mould for the production of each corner beads and with the additional drawback that
the standard foam material used to make the corner beads releases particles that filter
into the flame openings on the burners, creating difficulties.
[0004] FR-2607 789 describes a packaging for cooking hobs comprising two parts or half boxes
made of polyestyrene, the top one having cavities to house secured the burner heads.
Disclosure of the invention
[0005] The object of the invention is a packaging for the transport of gas stoves or cookers
which includes two or more foam plastic beadings to protect it, a plastic thermoshrinkable
sheet wrapping the corner beads and cooker, and means for securing the burners against
the cooker plate to ensure that they cannot move during transport. In addition to
being economical to make and usable with all size burners, they are easy to fit and
remove and do not leave substances or particles on the burners which require cleaning
or which subsequently affect combustion.
[0006] The means for securing the burners to the cooker to ensure that they do not move
during transport are, in a embodiment of the invention, a plastic tray with several
cylindrical receptacles of different diameters to house each burner individually,
formed peripherally with four vertical hollow sides, in such a way that when placed
in the central opening between the corner beads, fit onto the cooker grill through
a skirt that extends said peripheral sides downwards, and the burner securing tray
is covered together with the corner beads into the thermoshrinkable sheet which fits
to the level of the upper edges of the peripheral sides, covering the central opening
in the tray without touching the burner heads and preventing the burners from tipping
from their housings, since the gap between the burner head and thermoshrinkable sheet
is smaller than the diameter of the head.
Description of the drawings
[0007]
Figure 1 is a plan view of the cooker and the packaging object of the invention, without
the thermoshrinkable sheet.
Figure 2 is a cross-section of the cooker and the packing along line I-I in figure
1.
Figure 3 is a plan view of the burner securing tray to hold them during transport.
Figure 4 is a cross-section of the tray along line III-III in figure 3.
Preferred embodiment of the invention
[0008] With reference to figures 1 - 4 showing a preferred embodiment of the packaging 1
which is the object of the invention for a gas stove on top cooker 2, the packaging
comprises two corner beads 3 made of polymeric foam around the four sides of the cooker
2, leaving a central opening 4 where the tray 5 is placed for securing the burners
6, square-shaped and configured with four vertical sides 8 fitted onto the cooker
grate 12 and also wrapped up in the thermoshrinkable sheet 7 which, when tightened,
presses the upper edges of the peripheral sides 8.
[0009] The gas cooker 2 which is flat in the example described has the control panel 11
and the grate 12 for four burners, both covered by the corner beads 3, which enclose
the grate at the periphery only. Two supports 13 project from the grate for the cooking
vessels.
[0010] The tray 5 for securing the burners during transport is made of moulded plastic,
such as polystyrene, with a wall of even thickness and thin throughout all its sections,
approximately 0.6 mm thick, making it both flexible and resistant. The tray 5 is formed
by said hollow vertical sides 8 which extend downwards in an outer skirt 9 which forms
their hollow insides 10 into which the grate support protrusions 13 fit tightly, the
tray base 14 at the halfway level of said peripheral sides 8, and a number of cavities
15, e.g. four, drawn in the base 14, where the burner heads 6 are fitted without projecting
therefrom.
[0011] The thermoshrinkable sheet 7 wraps the entire stove assembly 2 and corner beads 3
above the opening in the tray 5, and once shrunk remains at a short gap 16 from the
base 14 of the tray, preventing the burners 6 from falling out of their housings 15.
[0012] To remove the packing after transport, the securing tray 5 is taken out easily by
placing the fingers in the hollows 17 drawn between the cavities 15, and pulling it
upward easily because of its material and thickness, the tray wall is relatively flexible.
[0013] The thickness of the bottom 18 of the burner containers is the same thickness as
the rest of the tray, but its surface is grid-formed to strengthen it to bear the
burner head weight.
