This leaves a cup top opening 92 of at least half the area of a completely uncovered (open) cup top, out of which a person can withdraw a first food such as a slice of apple, and dip it into a second food such as yogurt that lies in the cup recess 40 . This also results in the center of gravity of the weight of the second food in the cover recess plus the cover weight, lying approximately over the cup rim location 88 , so the cover does not have a strong tendency to tip over.

- the cover 14 has a rim portion with an undercut (as viewed from below) groove 130 and the third container has a corresponding rim portion at opening 133 that closely fits and is trapped in the undercut groove 130 .
- a person insets a finger into a gap 134 of the cup recess ( FIG. 13 ) and grasps the rim 136 of the third container 122 and pulls the third container up out of the cover recess 40 .
- the invention provides a food container arrangement of plastic sheeting that includes a cup and cover that can hold first and second foods, respectively, which enables the arrangement to lie in a first closed position or a second opened position.
- the cover In the second position the cover is held securely over the cup with a considerable opening left in the cup open top, and with the cover balanced on the cup rim and enabling the cup to be held in an auto cup holder.
- the cup and cover can provide tamper evidence by joining the cup and cover portions of a single sheet of plastic along a tear line that is torn the first time the cover is opened.
- the container arrangement can include a third container that nests in the cover and is latched in place.

Abstract
Description
- There are many foods that are best packaged separately but eaten together. These include french fries and ketchup, apple pieces and yogurt, and tortilla chips and salsa. A food packaging system that packaged the foods separately in closed containers, but allowed the opened containers to be securely held together so at least two foods could be conveniently held together, would be of value. When the opened containers are held together, it is desirable that they be held in the same manner as a single container, such as with one hand when a person is walking, or as a soda can or cup held in a vehicle cup holder. It also would be desirable if the closed containers clearly indicated if they had been already opened (after a clerk loaded food into the containers) so the buyer could be assured that no one had already opened them to sample the food and possibly contaminate it.
- In accordance with one embodiment of the invention, a low cost food container arrangement is provided that holds two different foods in separate closed containers, that allows the opened containers to be securely hold together in a manner that facilitates eating the foods together, and that assures the customer that the container has not been previously opened. The packaging system comprises plastic sheeting that forms a cup, and a cover that closes the open top of the cup in a first cover position. The cover is mountable in a second position on the rim of the cup so the cover extends horizontally with part of the cover lying over the cup open top and part of the cover extending horizontally beyond the open top of the cup.
- The cover has an upper surface with a groove, and the cover can be turned upside-down and the groove moved down to receive the cup rim. This mounts the cover on the cup, with a portion of the cover lying directly over the cup open top and with a portion of the cover lying beyond the cup rim but at the same height as the cup rim. The cup then can be easily held in a vehicle cup-holder that is designed to hold ordinary cups. One side of the cover groove has a sideward projection, and the cup rim has an L-shaped undercut insertion slot. The cover can be moved down and turned in the L-shaped insertion slot to lock the cover in place.
- The cup and cover can be formed of a single piece of plastic, with the cup and cover having flat joining parts lying facewise adjacent and connected by a tear joint along which the plastic sheet is weakened. The first person to open the container arrangement, tears along the tear line, which makes it obvious that the cup has been opened.
- In another embodiment of the invention, a third container is mounted in a cover recess.
- The novel features of the invention are set forth with particularity in the appended claims. The invention will be best understood from the following description when read in conjunction with the accompanying drawings.

FIG. 1 shows a packaging system, orcontainer arrangement 10 of the present invention, which is formed of polymer material such as plastic sheeting of 0.020 inch thick PETE (polyethylene terephthalate). The container arrangement includes acup 12 and acover 14, formed of asingle piece 20 of sheet plastic. The cup has avertical axis 22 and has arim 24 that extends around a majority of the axis, and the cover has acover axis 26. The cup also has a joiningportion 30 that initially joins to a joiningportion 32 of the cover, along atear line 34. At a facility where food is loaded into the cup, such as at a store or distribution facility, a clerk loads a first food into thecup 12. The clerk also usually loads a second food into arecess 40 in thecover 14, and closes the cover recess using a peal-off film (not shown) that initially adheres to a cover film-attachment surface 42. The clerk then may close the cover on the cup, with acover seal 44 that seals to acup seal 50. In the closed position of the cover, seals or sealingportions FIG. 2 shows the cover closed on the cup. - In the closed position of the cup, the cup can be opened by tearing the apart the cover and
cup joining portions 32, 30 (FIG. 1 ) along thetear line 34. This can be done by pulling up on one of twopull tabs FIG. 5 , when the cover is closed thecup rim 24 hasempty spaces 62, 64 that lie under thepull tabs tear line 34, as by multiple perforations that facilitate tearing the plastic and with aslit 66 leading to a joined tear line location of the cover and cup. After the tear line is torn so the cup and cover are separated along the tear line, the cup and cover can be closed on the cup in a first position shown inFIG. 2 . The only observed difference is that the radiallyouter ends 70, 72 (FIG. 12 ) of the joiningportions gap 74. Applicant forms abump 76 in a least one of the joiningportions gap 74 that is large enough to be readily seen after the tear joint has been torn. Thegap 74 provides evidence of tampering before the cover is torn off. If the tamper evidence feature of the tear line is not required, then the cup and cover can be formed of two sheets of plastic. - FIG. I shows that the
cover 14 has agroove 80 with a curvature corresponding the curvature of thecup rim 24.FIG. 3 shows that after thecover 14 has been separated from the cup, thecover 14 can be mounted on thecup 12 in a second position of the cover. In this second position, thecover groove 80 receives thecup rim 24. Thecover groove 80 andcup rim 24 form interfitting attachment parts that hold the cover in the second position ofFIG. 3 , over the cup. In the second position ofFIG. 3 , the cover lies with onecover part 82 lying directly over the cupopen top 84 which lies within thecup rim 24, and with anothercover part 86 lying horizontally beyond thecup rim 24. That is, the beyondcover part 86 lies at the same height as the directly-overcover part 82. The fact that the beyondcover part 86 lies at about the same height as the directly over cover part, results in the cup being mountable in an auto cup holder that surrounds most of the height of the cup.FIG. 1A shows thecup 12 lying in a recess E of a cup holder surface H, with thecover 14 lying over a raised auto part G that lies above the height of surface H. The figure also shows first and second foods F1, F2 in the two containers. - As shown in
FIG. 4 , the beyond coverpart 86 extends horizontally beyond the cup rim 24 a maximum distance that is close to half the cover diameter A. That is, the beyond coverpart 86 and the directly-overcover part 82 each extends between one fourth and three fourths, and preferably between one third and two thirds, of the rim diameter B from therim edge location 88 that lies closest to thefar end 89 of the cover rim. This leaves a cup top opening 92 of at least half the area of a completely uncovered (open) cup top, out of which a person can withdraw a first food such as a slice of apple, and dip it into a second food such as yogurt that lies in thecup recess 40. This also results in the center of gravity of the weight of the second food in the cover recess plus the cover weight, lying approximately over thecup rim location 88, so the cover does not have a strong tendency to tip over. - To prevent cover tip-over, applicant forms the cover as shown in
FIG. 13 , with aninsertion slot 100. As shown inFIG. 14 , the insertion slot is L-shaped (as seen in a mirror image), with avertical slot part 102 that extends down into the radially (with respect to the cup axis 22) inside of thecup rim 24, and with a circumferential undercutslot part 104 that extends circumferentially (with respect to the cup axis) from the bottom of the vertical slot part. As shown inFIG. 6 , thecover groove 80 has agroove side wall 110 with aprojection 112 that projects toward theother groove wall 114. As shown inFIG. 14 , the walls of thecover groove 80 are lowered onto the cup rim with theprojection 112 moved down along thevertical part 102 of the insertion slot. Thecover 14 is then moved indirection 116 approximately 40° (5° to 60°) around the cup axis, to move theprojection 112 along the undercut insertion slotcircumferential part 104. This latches the cover to the cup, with the cover straddling the cup rim as shown inFIG. 15 . -
FIG. 13 shows acontainer arrangement 120 that includes athird container 122, in addition to thecup 12 andcover 14. Thethird container 122 is held in therecess 40 of the cover, with the third container holding the second food instead of placing the second food in the cover recess. The advantage of this arrangement is that the third container can be securely sealed with a lid in the form of alid film 124 at a factory, and that the third container is of a regular shape with tapered largely-cylindrical side walls and without grooves etc.FIG. 8 shows thethird container 122 lying upside-down in the upside-down cover 14, with the third container opening 133 facing, or opening, downward, and with thelid 124 covering the opening. As shown inFIG. 10 , thecover 14 has a rim portion with an undercut (as viewed from below)groove 130 and the third container has a corresponding rim portion at opening 133 that closely fits and is trapped in the undercutgroove 130. To remove the third container a person insets a finger into agap 134 of the cup recess (FIG. 13 ) and grasps therim 136 of thethird container 122 and pulls the third container up out of thecover recess 40. - Thus, the invention provides a food container arrangement of plastic sheeting that includes a cup and cover that can hold first and second foods, respectively, which enables the arrangement to lie in a first closed position or a second opened position. In the second position the cover is held securely over the cup with a considerable opening left in the cup open top, and with the cover balanced on the cup rim and enabling the cup to be held in an auto cup holder. The cup and cover can provide tamper evidence by joining the cup and cover portions of a single sheet of plastic along a tear line that is torn the first time the cover is opened. The container arrangement can include a third container that nests in the cover and is latched in place.
- Although particular embodiments of the invention have been described and illustrated herein, it is recognized that modifications and variations may readily occur to those skilled in the art, and consequently, it is intended that the claims be interpreted to cover such modifications and equivalents.
