DETAILED DESCRIPTION OF THE INVENTION
The above described drawing figures illustrate the invention in at least one of its preferred embodiments, which is further defined in detail in the following description.
The present invention is an apparatus for directing the cutting of a cake
19
, or similar baked goods, along a plurality of straight lines. Plural cuts may be made to section the cake
10
as desired. A first embodiment of the invention is a combination of a cake pan
20
, which may be made of metal, plastic, glad or similar materials, and a straightedge ruler
30
made of a rigid material- The pan
20
is adapted for containing the cake
10
during baking in that it has a pan bottom
22
and a peripheral pan sidewall
24
integral with the pan bottom
22
and directed upwardly therefrom and terminating with a pan sidewall edge
26
as shown in FIG.
1
.
FIG. 1
depicts a rectangular cake pan
20
, but it may be any shape including round, square, triangular, etc. The sidewall edge
26
provides plural guide pins
40
engaged therewith and which extend vertically upwardly therefrom. The guide pins
40
each have a preferably circular cross-section for specific reasons to be discussed. The straightedge ruler
30
has a straight edge
32
of a length sufficient to span the pan
20
from any one selected position on the sidewall edge
26
to any further selected position on the sidewall edge
26
so that cuts may be made laterally, longitudinally and diagonally within the cake pan
20
. Linear indicia are positioned on the pan bottom indicating plural possible cake cuts. The straightedge ruler
30
is preferably of a transparent material, such as acrylic plastic, for improved visibility in drawing cuts in the cake
10
.
The guide pins
40
are positioned such that with the straightedge ruler
30
engaged with any selected pair of the guide pins
40
, the straight edge
30
is positioned for guiding straight-line cutting of the cake
10
in a desired location
5
on the cake
10
corresponding with the position of the straight edge
32
. Clearly, the pins
40
may be placed so as to cut square, rectangular, triangular and diamond shaped portions of the cake
10
. Other shapes are not excluded from the capability of the present invention. Preferably, the straightedge
32
is sufficiently wide so that a cutting implement
50
may be maintained in a vertical orientation by strongly pressing it against the straightedge
32
as it is drawn along.
Preferably, the straightedge ruler
30
provides a longitudinal slot
34
for engaging the guide pins
40
. In this manner the slot
34
may be engaged with the pins
40
so that the slot
34
is aligned with the center of the pins
40
and the cutting implement
50
, for instance a knife, may be inserted into the slot
34
and drawn across the cake accurately aligned with the center of the pins
40
. Another advantage of the slot
34
in the ruler
30
is that the ruler
30
may be directed in any direction desired to make longitudinal, lateral or diagonal cuts without loss of precision. This enables the cake
10
to be cut with improved symmetry and uniformity of the finished cake pieces. The fact that the pins
40
are round in section enables the ruler
30
to be swiveled in any direction with the ruler slot
34
pivoting about any one of the guide pins
40
.
In a further embodiment of the invention, preferably made of plastic by an injection molding process, well known in the art, for use when a cake pan
20
does not provide the guide pins
40
, the guide pins
40
are mounted on a cake pan insert
60
having a continuous inner lip
62
, shown in
FIG. 2
, adapted for peripheral engagement with an inner surface
25
of the cake pan sidewall
24
, and a continuous outer lip
64
, integral with the inner lip
62
, and positioned for resting on the sidewall edge
26
of the sidewall
24
.
In the case where the pan insert
60
is rectangular in shape, as shown in
FIG. 2
, it is made up of four straight portions
65
,
66
,
67
, and
68
joined end-to-end. These engage the rectangular cake pan
20
. Each pair of the straight portions is joined by a hinge
69
, preferably a, so-called living hinge, comprised of a thin portion of the plastic formed as a flexible web, whereby the pan insert
60
may be folded relatively flat for storage when not in use as shown in FIG.
4
. In this case, the hinge
69
joins the inner lip
62
of adjacent straight portions, while the corresponding outer lips
64
are separated by a slit
70
.
The method of use of the present invention for cutting a cake comprises the steps of placing an inner lip
62
of the cutting guide insert
60
against the inner surface
25
of the cake pan
20
, resting the outer lip
64
of the cutting guide insert
60
on the edge
26
of the cake pan
20
, placing the straightedge ruler
30
into contact with a selected pair of the guide pins
40
and preferably with the guide pins inserted in the slot
34
of the ruler
30
, and then drawing a cutting implement
50
along the straightedge ruler
30
, preferably in the slot
34
, to cut the cake
10
. This same procedure is repeated until the cake
10
is sectioned in accordance with plan, with some of the possibilities shown in FIG.
3
. The method further comprising the step of folding the cutting guide
40
for storage as shown in FIG.
4
.
While the invention has been described with reference to at least one preferred embodiment, it is to be clearly understood by those skilled in the art that the invention is not limited thereto. Rather, the scope of the invention is to be interpreted only in conjunction with the appended claims.
