Abstract

A tray for packaging a plurality of individual servings. The tray has a plurality of cups arranged in a two-dimensional array of cups joined at their abutting rims. A cover sheet extends over and is sealed to the rims. Weakened lines of separation, such as a series of perforations, between the cups facilitate manual separation of individual cups from the remainder of the tray with the need for tools.

BACKGROUND OF THE INVENTION
• 1. Field Of The Invention[0004]
• 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.[0005]
• 2. Description Of The Related Art[0006]
• 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.[0007]
• 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.[0008]
BRIEF SUMMARY OF THE INVENTION
• 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.[0009]

• 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.[0013]
(h) DETAILED DESCRIPTION OF THE INVENTION
• As illustrated in FIGS.[0014]1-3, an embodiment of the invention has atray10 comprised of a two dimensional array ofindividual cups12 joined together at their adjacent rims. Preferably, thetray10 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 individualportion control cups12 that are joined together along aligned perforations14 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.
• Each[0015]cup12 is generally rectangular with rounded corners, having ashort edge16 extending for about one inch, and along edge18 extending for about 2¼ inches, between the rounded corners. Eachcup12 is about ⅝ inch deep. Arim22 extends outwardly from eachcup12 and has anouter edge24. Therim22 is about {fraction (3/16)} inch wide and also has rounded corners. Thecup12 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.
• A[0016]cover20 is hermetically sealed to therim22 of eachcup12, such as by heat sealing, an adhesive or other conventional means. Thecover20 for thecup12 shown in FIG. 3 has been omitted to reveal the interior of the cup. Thecover20 has anexcess portion21 that extends past theouter edge24 of therim22. Theexcess portion21 of thecover20 is easily grasped for peeling thecover20 from therim22. Thecover20 can be foil, flexible plastic, or similar material commonly used for preserving food or covering such trays. Preferably thecover20 is a plastic film that routinely tolerates the usual temperatures at which frozen food is stored.
• 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[0017]14 are formed transversely and longitudinally along two series of parallel lines through thecover20 and the mutual region of plastic between eachadjacent cup12. The perforations14 define the abuttingouter edge24 of therim22 of eachadjacent cup12. There must be a generous amount of the perforations14 for thecup12 to allow a consumer to easily separate a single cup from the remaining tray ofcups10 by tearing along the perforations14. 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 perforations14 per inch, and the perforations14 are spaced about {fraction (1/16)} inch apart. The perforations14 can be formed using a tool, such as awheel30 with several small blades orpins32, 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.
• Preferably, each[0018]cup12 has a capacity to bold ¾ 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.
• 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.[0019]
• Each[0020]cup12 preferably has afill line indentation13 to indicate the level to which the cat food is filled. It is preferred that thecup12 is flat and shallow, so the cat may easily consume the food directly from thecup12. However, thecup12 may be circular, and various other shapes could be used. In addition, the ¾ ounce portion is a typical serving suggestion for the cat, so thecup12 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.
• 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.[0021]
• 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.[0022]
