[0001] This application claims the benefit of U.S. Provisional
Application No. 60/366,973, filed Mar. 22, 2002.
STATEMENT REGARDING FEDERALLY-SPONSORED RESEARCH AND
DEVELOPMENT
[0002] (Not Applicable)
REFERENCE TO AN APPENDIX"
[0003] (Not Applicable)
BACKGROUND OF THE INVENTION
[0004] 1. Field Of The Invention
[0005] This invention relates generally to packages for individual
servings of food, and more particularly to cups for packaging a
serving of a frozen novelty food for felines.
[0006] 2. Description Of The Related Art
[0007] Portion control cups are used for packaging a food in
readily consumable serving portions not exceeding two ounces.
Typically, portion control cups are designed to hold an amount of
the food suggested to be an individual serving. Portion control
cups have not been designed particularly for an individual serving
of a frozen food. Usually, portion control cups hold condiments
such as ketchup and barbecue sauce, or jelly.
[0008] Generally, portion control cups are made from a heated sheet
of plastic that has cup shapes pressed or vacuum formed into the
sheet, which forms a tray of joined plastic cups. Each cup is
removable from the tray by severing a rim of plastic that surrounds
each cup in the sheet. Then, still in tray form, the individual
cups are filled with the food. After the cups are filled, a plastic
or foil cover or a cap is sealed to each cup.
BRIEF SUMMARY OF THE INVENTION
[0009] The invention is a tray of plastic cups joined together at a
rim of each cup. Each cup has a shape and volume for packaging a
frozen novelty food for felines. The rim of each cup has an outer
edge abutting that of an adjacent cup. A cover is fitted over the
tray of cups and sealed to the rim of each cup. Perforations are
formed through the tray sheet material and the cover between the
abutting outer edges of the respective rims to permit each
individual cup to be manually severed or torn from the tray by a
consumer without the need for tools, such as a knife or scissors,
rather than severing the individual cups during manufacturing which
is the common practice. An excess portion of the cover extends past
the outer edge of the rim of each cup for grasping to remove the
cover from the rim.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS
[0010] FIG. 1 is a view in perspective illustrating an embodiment
for the invention.
[0011] FIG. 2 is a view in perspective illustrating the preferred
embodiment for the invention.
[0012] FIG. 3 is a view in perspective illustrating an individual
serving cup unit separated from the tray shown in FIG. 2.
[0013] In describing the preferred embodiment of the invention,
which is illustrated in the drawings, specific terminology will be
resorted to for the sake of clarity. However, it is not intended
that the invention be limited to the specific term so selected and
it is to be understood that each specific term includes all
technical equivalents, which operate in a similar manner to
accomplish a similar purpose.
(h) DETAILED DESCRIPTION OF THE INVENTION
[0014] As illustrated in FIGS. 1-3, an embodiment of the invention
has a tray 10 comprised of a two dimensional array of individual
cups 12 joined together at their adjacent rims. Preferably, the
tray 10 is initially manufactured with sixteen cups, as illustrated
in FIG. 1 and, after filling with the food, is cut in half to form
two trays each having eight individual portion control cups 12 that
are joined together along aligned perforations 14 as illustrated in
FIG. 2. Cutting the sixteen cup tray in half to form two trays of
eight cups provides a tray having the preferred size for packaging
in a paperboard container for retail sales. Retaining the cups
joined together at the perforations allows for the simplified
loading of an entire tray of eight cups into the carton without the
need to use a cup holding apparatus and other expensive mechanical
equipment to insert an array of separated individual cups into the
carton.
[0015] Each cup 12 is generally rectangular with rounded corners,
having a short edge 16 extending for about one inch, and a long
edge 18 extending for about 21/4 inches, between the rounded
corners. Each cup 12 is about 5/8 inch deep. A rim 22 extends
outwardly from each cup 12 and has an outer edge 24. The rim 22 is
about {fraction (3/16)} inch wide and also has rounded corners. The
cup 12 is made of plastic sheet material, typically polystyrene,
that may be of a type conventionally used for making such trays and
cups and that is about one millimeter thick and routinely tolerates
the usual temperatures at which frozen food is stored, such as by
not becoming brittle at those temperatures.
[0016] A cover 20 is hermetically sealed to the rim 22 of each cup
12, such as by heat sealing, an adhesive or other conventional
means. The cover 20 for the cup 12 shown in FIG. 3 has been omitted
to reveal the interior of the cup. The cover 20 has an excess
portion 21 that extends past the outer edge 24 of the rim 22. The
excess portion 21 of the cover 20 is easily grasped for peeling the
cover 20 from the rim 22. The cover 20 can be foil, flexible
plastic, or similar material commonly used for preserving food or
covering such trays. Preferably the cover 20 is a plastic film that
routinely tolerates the usual temperatures at which frozen food is
stored.
[0017] Of critical importance to the invention is the provision of
weakened lines of separation between the individual cups in order
to facilitate manual separation of the cups by the ultimate
customer so the food can be served in individual servings. For this
purpose, spaced perforations 14 are formed transversely and
longitudinally along two series of parallel lines through the cover
20 and the mutual region of plastic between each adjacent cup 12.
The perforations 14 define the abutting outer edge 24 of the rim 22
of each adjacent cup 12. There must be a generous amount of the
perforations 14 for the cup 12 to allow a consumer to easily
separate a single cup from the remaining tray of cups 10 by tearing
along the perforations 14. The uncut material between the
perforations should be long enough to hold the cups together during
normal production, filling and loading of the cups into the carton,
but short enough to manually tear when a consumer manually
separates a cup for serving. Preferably, there are about fifteen of
the perforations 14 per inch, and the perforations 14 are spaced
about {fraction (1/16)} inch apart. The perforations 14 can be
formed using a tool, such as a wheel 30 with several small blades
or pins 32, as shown in FIG. 2, or a straight edge with similar
blades or pins (not shown). Although, instead of perforations, the
tray material, and/or the cover material may be made thinner along
the same lines illustrated in the figures to form a tear line, this
in not preferred because it is believed to be a more difficult
manufacturing operation, to provide a less reliable tear line and
to be more difficult for a customer to separate individual
cups.
[0018] Preferably, each cup 12 has a capacity to bold 3/4 ounce of
a frozen novelty food for a cat. This is the preferred volume and
is important for biological reasons. Specifically, it is
undesirable for a frozen treat to melt and require that it be
refrozen or discarded as waste. As with any food product, it is
also undesirable for it to sit unrefrigerated for a long period of
time. The preferred cup capacity provides a quantity that is
typically consumed by a cat within one hour when served free
choice.
[0019] The above described dimensions of the cup are also
important. These dimensions simultaneously provide not only a
capacity that is typically consumed by a cat within an hour but
also do so in a manner that provides a flat, shallow configuration
which is easy for a small animal to consume directly from the cup
when the food treat is offered.
[0020] Each cup 12 preferably has a fill line indentation 13 to
indicate the level to which the cat food is filled. It is preferred
that the cup 12 is flat and shallow, so the cat may easily consume
the food directly from the cup 12. However, the cup 12 may be
circular, and various other shapes could be used. In addition, the
3/4 ounce portion is a typical serving suggestion for the cat, so
the cup 12 holds an amount of the food that is generally totally
consumed by the cat, thereby avoiding having to re-freeze a
leftover portion of the food.
[0021] As a further alternative, the cups can be joined only by the
cover sheet with individual cups which are not joined by the cup
sheet material. However, this is not preferred because the cover
material will either be so thin that the tray of cups will readily
fold and be more difficult to manipulate or the cover material will
need to be made thicker in order to be more rigid.
[0022] While certain preferred embodiments of the present invention
have been disclosed in detail, it is to be understood that various
modifications may be adopted without departing from the spirit of
the invention or scope of the following claims.
