Background of the Invention

Several people eating together may use a set of identical items for eating or drinking, such as cutlery, plates, cups, drink six-packs, etc. Disposable eating utensils are widely used at parties, picnics, etc. It is very convenient to use the plates, cups, forks, etc. without the need to clean them, dry and store them afterwards. The disposable utensils are simply thrown away, together with whatever waste they may contain.

MIZ-CUPB -2 -Marc Zuta and Idan Zuta A problem with such utensils is that they are unmarked; a person has to keep them at hand, else he/she will not be able to distinguish them from someone else's plate or cup. During a party a person may need to leave his/her place, for example to go to the toilets, to dance, meet people, etc. That person, on return, will not know for sure which is his/her plate.

When considering the dangers of catching any of a multitude of infectious diseases, it will become apparent that this trivial problem may have disastrous consequences.

Therefore, it is important for a person to be able to identify his/her plate or cup at a party, even if these are just disposable items. Before and after use, they are just cheap, disposable items. However, whilst they are still in use by a guest they become important personal items.

Unidentified cups may cause waste -a person leaves her cup for a moment, and later she is not sure which is her cup. She will take a new cup or plate anyway.

As the process is repeated by more people, a large quantity of cups and plates may be used and thrown away unnecessarily, together with whatever food or drink they may contain.

Another problem at such parties or events is that people are often outside of their normal, familiar environment. People may not feel "at home", and naturally they may wish to mark their place/ location/ territory during the event. They may leave their bag or a personal item there, however such an item may be stolen. If this is the bag with the keys and credit cards, that person has a real problem.

MIZ-CUPB -3 -Marc Zuta and Idan Zuta

Summary of the invention

There is provided a set of identical items for eating or drinking, wherein each item in the set can be uniquely distinguished by its user. The user is sure in the knowledge that he/she will not eat or drink from another's item.

There is provided a pack of cups wherein each cup is guaranteed to have a unique marking, to distinguish it from all the other cups in that package.

The marking is visual and preferably easily recognizable from a distance and from various angles, for example numbers, words, sentences and/or pictures.

Colors may be used, however colors may not serve to reliably distinguish items, because some people may be color blind.

Thus, when a person picks a cup with the number "6L" thereon, he may leave it on the table and return later to recover it, sure in the knowledge that this is indeed the cup which he/she has previously left there.

That person can then continue to use the same plate or cup on return.

Moreover, that cup or plate may serve to mark his/her temporal "territory" or place, without putting much at stake -in the worst case, just a cheap plastic plate is lost.

The new system and method may be also applied to plates, forks, knives, spoons and various other disposable utensils.

Furthermore, assorted sets may be formed as well, wherein a guest may pick a plate with the name "Mark Twain" and a cup and a fork with that same name thereon.

This offers the added benefit that now several utensils are personalized, and yet that person has only to remember one name or number.

According to yet another aspect of the invention, a display is provided which presents all the names, numbers, pictures, etc. in the package.

A guest may choose and pick that symbol which he likes most. This may serve as an icebreaker at a party, to convey a message to people there.

MIZ-CUPB -4 -Marc Zuta and Idan Zuta A marking system may be used to uniquely mark disposables, to convert otherwise identical items into personalized eating or drinking utensils.

An efficient manufacturing system for concurrently marking a group of disposable items is disclosed.

Furthermore, a vending machine for selling uniquely marked disposable items is disclosed as well.

The present invention may be used to uniquely mark items which are not disposable, for example to aid guests to personalize the cutlery they use.

Therefore, the invention may be used to uniquely mark plates, cups, etc., which are not disposable.

The invention generally relates to these innovative issues, among others: A. A set of uniquely marked disposable items for eating and drinking, for example a set of cups, a set of plates or a set of forks.

B. An assorted set of uniquely marked disposable items for eating or drinking for example a set of cups AND a set of plates AND a set of forks.

C. A system for creating an uniquely marked disposable set, out of a set of indistinguishable items.

D. A manufacturing system for creating a set of uniquely marked items manufacturing -cups or cans with imprinted/embossed/engraved markings print/emboss on paper/aluminum sheet prior to making can.

print directly on can or bottle, or use plastic/paper cover/coating E. A vending machine, delivers uniquely marked items. Either by selling uniquely marked disposable items stored in the machine, or by uniquely marking each of the disposable items stored in the machine prior to its delivery to a customer.

F. labels for marking: single set; assorted set.

Detailed Description of the Preferred Embodiments

The invention will now be described with reference to the drawings.

A. A set of uniquely marked disposable items for eating and drinking As illustrated in Fig. 1, the invention discloses a package 11 with uniquely marked disposable cups 21. Each cup 21 has a unique mark 213 thereon, and optionally also a common mark 215, to identify the set as a whole.

The common mark 215 help prevent using items from several packages at the same event, in which case the same marking may recur.

The package may also include sealing means 12 for the package -thus, the customer breaks the seal in the knowledge that it contains a set of disposable items, each with a unique mark thereon.

The customer may choose a package with 100, 200 or 500 cups, for example, according to the number of guests expected at a specific event.

The system may also include a package 13 with uniquely marked disposable plates 31.

Each plate 31 has a unique mark 313 thereon, and optionally also a common mark 315 to identify the set as a whole.

The common mark 315 is used to ensure that only one set is used at a time at one event, thus ensuring that each mark occurs just once.

The common mark 315 may be applied and used according to either one of two possible methods, as detailed below.

MIZ-CUPB -7 -Marc Zuta and Idan Zuta Method 1 for using the common mark 1. One package contains the required number of items to be used at one event, therefore only one package is expected to be used there -for example by buying a pack of 200 cups.

2. Different packages have the same set of marks, for example the numbers 1,2,3... 200 in the above case.

3. Identical packages are marked with different common marks, to ensure that no items from two packages are mixed and used at one event.

If items from two packages were to be mixed, then two items with identical markings may occur, a forbidden occurrence.

1,* After using part of the items in a package, the host can verify that he/she may take more items from the package, by comparing the common mark on the package with the common mark on items already in use at that event.

If the common mark is the same, then the host is permitted to draw more items from that package at that event.

Method 2 for using the common mark 1. One package contains less than the required number of items to be used at one event, therefore more than one package is expected to be used there -for example many six-packs of beer may be used at a party.

2. Different packages in the same group have different sets of marks, for example the numbers 1 to 6 in one package, 7 to 12 in another, 13 to 18 in yet another, etc. 3. Identical groups of packages are marked with different common marks, to ensure that no items from two groups are mixed and used at one event.

If items from two groups were to be mixed, then two items with identical markings may occur, a forbidden occurrence.

MIZ-CUPB -8 -Marc Zuta and Idan Zuta 4. When buying packages for an event at the supermarket, the host of the party will ensure that all the packages have the same common mark. This ensures that the whole group has just one of each item -that is, each item has unique markings over all the packages acquired.

5. After using part of the six-packs, the host can verify that he/she may bring more six-packs (or packages of items), by comparing the common mark on the package with the common mark on items already in use at that event.

If the common mark is the same, then the host is permitted to draw more items or packages at that event.

There are also optional sealing means 14 for the package. The sealing means may be used to ensure that the package has not been tampered with, therefore the package offers the promised benefits -that there are indeed the number of items as specified ( i.e. 100, 200, etc.) and that these items are uniquely marked as guaranteed by the manufacturer.

Means for marking Various devices and methods may be used to uniquely mark each item of a

group, for example:

1. Printing 2. embossing, using pressure, heat, ultrasonic waves or a combination thereof.

3. attaching labels with unique markings to the items. Attaching using glue, heat and/or pressure, for example.

4. cutting the mark off the item, for example using mechanical cutting means, laser means, etc. Preferably, the labels are adapted to the intended use. For example, labels for cups should withstand extremes of temperature, organic acids, fats, etc. The glue should not be poisonous or dangerous if swallowed.

MIZ-CLJPB -9 -Marc Zuta and Idan Zuta The labels with unique markings thereon, may be stored in storage means and ready for applying to the items.

Each label should have a measure of flexibility and/or extendibility to adapt to the shape of the item it is to be attached to.

Various means may be used to attach labels to disposable items.

These may include a glue, microwaves, ultrasonic waves, infrared, hot air, laser, etc. B. An assorted set of uniquely marked disposable items for eating or drinking Fig. 2 illustrates an assorted set of cups 21, forks 41 and plates 31.

Although the mark 213 for each cup 21 is unique among the cups, there is a corresponding identical mark 413 for one fork 41 and a mark 313 for a plate 31.

Thus, the user can pick a cup, a fork and a plate, all with the same mark.

The user has only to remember one number for all the utensils he/she will use on that occasion.

The system includes a group of sets of disposable items (such as a set of cups, a set of forks, a set of plates, etc.); each set includes identical disposable items, each with a unique visual mark thereon, but for each mark there (such as the number "007"), there is one item in each group marked therewith.

Optionally, the items in each package are arranged in the same order of marking so, when a user will pick up one item from each package, all will have the same markings (such as the name "Ronny"). If someone took only items from part of the packages, the topmost item from the rest of the packages may be thrown away so again the marks come in sync (for example, a user took only the cup with the number "013" ; the cups package will deliver the next number 014, however the plates and forks packages will deliver the number 013).

MIZ-CUPB -10 -Marc Zuta and Idan Zuta This structure and method of arranging the marked items will facilitate picking up an assorted set of several items of different types, all with the same mark.

Fig. 3 details an assorted set with an external display of the contents of the package. The system includes a package with several storage volumes, for example a volume 52 for forks, a volume 53 for plates and a volume 54 for cups.

Display means 51 indicate all the marks in use, such as "Joel" , "Cat" , etc. This may help a user to pick utensils with a desirable mark to them.

A user may cross on the display the mark picked, so others will not look anymore for that mark.

C. A system for creating an uniquely marked disposable set Fig. 4 details a system for personalizing existing disposable items for creating a unique set ad hoc, prior or during a party for example, on the user's premises.

The display means 61 displays electronically all the available marks to a user.

The user then activates the data entry means 62 (such as a keyboard and/or a computer mouse) to enter the chosen mark into the computer 63.

The printing/engraving means 64 are used to mark a disposable item 31 (a plate in this example) with the chosen unique mark.

The computer program will update its storage, to remove the chosen mark from the list of available marks, so the next person will only be allowed to chose another unique mark.

The system may allow a person to mark several utensils (i.e. a cup, a plate and a fork) with the same mark.

MIZ-CUPB -11 -Marc Zuta and Idan Zuta Thus, Fig. 4 details a system for personalizing existing disposable items for creating a unique set ad hoc.

The storage may include various pictures, slogans, etc., as chosen by the host. For example, at a children's party -wild animals or a space war theme.

The input/output means, such as a keyboard 62 and display 61, are used for presenting the various choices available to a guest, and for allowing him/her to enter their personal choice.

As existing symbols are used, they are automatically deleted from the display, to ensure that each quest will get a unique symbol -no symbol will be used more than once.

Mark applying means 64 include means for printing, engraving, sticking or otherwise attaching the chosen symbol to a guest's cup/plate/spoon, etc. The computer/controller means 63 is used for controlling the operation of the system as detailed above.

Method for supplying unique disposable items A method for supplying unique disposable items comprises: a. presenting or displaying available marks to a guest; b. accepting the guest's choice of a mark; c. supplying the guest with a disposable item with the chosen symbol, or a plurality of items, all with the chosen symbol; d. updating the list of the available symbols, so the next guest will not be able to chose one of the symbols which are already in use.

Optionally, the guest may choose the type of disposable he/she desires, for example a cup, knife or plate, or a combination thereof. The selected items will be supplied to the user, all with the chosen mark printed thereon.

MIZ-CUPB -12 -Marc Zuta and Idan Zuta Fig. 5 details a set of uniquely marked toothpicks 35.

The unique marking 351, 352, 353 in this case may contain a combination of a number and a shape, to allow more possible marks with fewer digits.

Fig. 6 details a six-pack 17 of beer cans 26, each with its unique marking 261, 262 -the mark may be printed on several locations on each can, to make it easily visible from any angle.

Two or more people may drink together and have a good time, yet they may desire not to mix their body fluids. Each person can discreetly keep to his/her can and only drink from it.

In a group, some of the people may be unaware of such personal preferences and may drink from other's cans. Still, a person desiring to use the protection provided by the present invention will be able to track the use of his/her personalized can by others, and refrain from further drinking from it in such case. The item is personalized only in the mind of the user, as that user is aware of, and remembers, the mark on the item he/she is using.

A group mark 172 may be used to indicate the range of marks for this particular six-pack; a user can then buy several six-packs, so that each can has a unique mark in the whole group.

For example, she will buy a six-pack marked "2X" containing cans 21 to 26, a six-pack marked "24X" containing cans 241 to 246, etc. Thus, the mark on the outside is common to the items within; each item within is marked with a subset of the mark displayed outside.

See the "Method 2 for using the common mark" above for an example of marking six-packs or other sets of identical items and for advantageously using such common marks at a party.

The invention may be used with various drinks such as beer or other alcoholic beverage or non-alcoholic drinks, in metallic cans or glass bottles or plastic bottles or various other packages.

MIZ-CUPB -13 -Marc Zuta and Idan Zuta Thus, the invention may be used to personalize disposable items which are otherwise indistinguishable. Such disposable items may include for example eating utensils or various drinks.

D. A manufacturing system for uniquely marked items Various embodiments of the invention may be used, for example: a. manufacturing -cups or cans with imprinted/embossed/engraved markings b. print/emboss on paper/aluminum sheet prior to making can.

c. print directly on can or bottle, or use plastic/paper cover/coating Fig. 7 details a top view of a manufacturing system for concurrently marking a group of disposable items 21.

Marking means 71, 72 mounted on two support means 713, 723 respectively are concurrently applied to the items 21 from two opposite sides, in one preferred embodiment. The support means 713, 723 move together toward the items 21 as indicated with the arrows in Fig. 7.

This embodiment may be used to advantageously hold the items 21 in place during marking.

The marking means 71, 72 may include printing means or engraving means or labels-applying means.

Means for applying labels: Labels with unique markings may be prepared in advance and stored in the machine, to be applied to cans or cups or bottles, etc. using a glue for example.

In another embodiment, marking is performed from one side of the items 21 only. The items 21 may be rotated by 180 or 120 arc degrees, etc. to mark them on more than one side.

MIZ-CUPB -14 -Marc Zuta and Idan Zuta Marking means 71, 72 mounted on two support means 713, 723 respectively are concurrently applied to a cup 21 from two opposite sides, in one preferred embodiment. The support means 713, 723 move together toward the items 21 as indicated with the arrows in Fig. 8.

Inner support/marking means 73, attached to holding means 733, is inserted in the cup 21 to hold it in place, mark it from the inside and/or provide back support for the marking means 71 and 72.

The system includes means for marking items in stages: 1. Loading disposable items to be marked into the marking system 2. Setting parameters for unique marking, or loading uniquely marked labels 3. Marking the disposable items, each with an unique mark and optionally with a comon mark also. Each item is preferably marked in several places, so the mark is visible from various angles without the need to pick it up or rotate it to do so.

Various devices and methods may be used to mark the items.

Marking may include several stages and/or machines, for example a machine for applying a glue, a second for applying labels and a third to dry it.

4. Unloading the marked disposable items from the marking system.

Marking means 74, 75 mounted on two support means 745, 755 respectively. The marks are then concurrently applied to a can 26 from two opposite sides, in one preferred embodiment. The support means 745, 755 move together toward the items 21 as indicated with the arrows in Fig. 9.

MIZ-CUPB -15 -Marc Zuta and Idan Zuta This embodiment may be used to advantageously hold the items 26 in place during marking.

Top support/marking means 76 with holding means 765 is applied from above to the can 26 to hold it in place and/or mark it on its top.

The marking means 74, 75 and 76 preferably move together towards the can 26 to hold it in place and apply unique markings to it.

In another embodiment, the top means 76 is the first to make contact with the can 26, to hold it in place, whereupon the means 74 and 75 also make contact with the can 26 to mark it.

In one embodiment, the disposable items are marked one at one time.

In another embodiment, a group of disposable items is marked together E. A vending machine, delivers uniquely marked items Fig. 10 details a front view of a vending machine for selling uniquely marked disposable items stored in the machine.

Cans 26 with unique markings thereon are mounted on conveyor means 81, which moves them towards gate/shutter means 82. The conveyor and the gate are activated when delivery to customer is approved, for example after the customer has selected the desired beverage and paid for it, to take the can to the outlet means 83, to be delivered to the customer.

The cans 26 are delivered in a prearranged order, so that cans sold within a predefined range are uniquely marked. After 100 cans in this example, the sequence of numbers will repeat, however, if a group is smaller than 100, then each member will receive a can with unique marking in that group.

Alternately, the cans may be sequentially numbered 1 to 200, 1 to 500, etc., so as to insure delivery of uniquely marked cans to the intended/maximal group of customers.

MIZ-CUPB -16 -Marc Zuta and Idan Zuta Fig. 11 details a front view of a vending machine for uniquely marking each of the disposable items stored in the machine prior to its delivery to a customer.

Cans 26 with no unique markings thereon are mounted on conveyor means 81, which moves them towards gate means 82. The conveyor and gate are activated when delivery to a customer is approved, for example after the customer has selected the desired beverage and paid for it, to outlet means 83 to be delivered to the customer.

Marking means 85 are used to uniquely mark each can or bottle prior to its delivery to a customer. For delivery to a group, the customer enters the number of items to buy with his/her order. The system will uniquely mark all the items for that order, whatever the number may be. The unique marking may be also applied to various types of drinks, if so desired and if the vending machine is programmed to do it.

F. labels for marking: single set; assorted set Labels for marking may be attached to items to confer on them the benefits according to the present invention. The labels may be uniquely marked and prepared in advance, prior to their application to the items to be uniquely marked.

The labels may be manually applied, or may be stored in a manufacturing or vending machine, to be applied during manufacture or storage or prior to delivery to a buyer.

MIZ-CUPB -17 -Marc Zuta and Idan Zuta The novel labels may be so devised, using materials and technologies known in the art, as to comply with various specs, for example: a. suitable for marking eating devices: non-toxic label and adhesive b. withstands extremes of temperature, fats, organic acids, water, etc. Various embodiments of the present invention will become apparent to persons skilled in the art upon reading the present disclosure together with the attached drawings. Other embodiments of the invention may be implemented, without departing from the spirit and scope of the present invention.
