Food Container
Field of the invention
The present invention relates to a food container and in particular to a disposable food container made of a plastics material or a flexible sheet material such as cardboard .
Background of the invention
There are currently available cardboard containers that are used by fast food outlets to store potato chips. When buying a meal to take away, a person will often buy a hamburger, potato chips in a container, and a drink in a cup. Carrying all these items while trying to eat is not an easy task.
US-A-4 , 620, 631 discloses a device for holding two containers, such as a beverage container and a food container. The device is formed of a strip of flexible material that is bent into a loop for receiving one of the containers and its ends are bonded to the outer surface of the other container.
A disadvantage of the above proposal is that a flat strip flexible wrapped around a container does not provide secure location of the containers relative to one another, especially if the containers themselves have flexible walls. As such containers are required to stack, they are also conically tapered and this adds to the difficulty of securely carrying both containers using the one hand.
Object of the invention
With a view to mitigating the foregoing problem, the present invention seeks to provide a disposable food
container that can be carried securely at the same time as a cup, using only one hand.
Summary of the invention
According to the present invention, there is provided a disposable food container having a compartment for holding food and carrying means for coupling the container to a cup so that the cup and container may be carried n one hand, characterised in that the carrying means comprise a flat flexible flap formed as an extension of one of the side walls of food compartment and a hole in the flap for receiving the cup, the flap, when in use, making contact with the cup only around the edge of the hole.
As earlier mentioned, disposable drinks containers, such as paper or plastics cups, are usually conical and taper downwards, to enable them to be stacked when they are empty. It might be thought therefore that if a flexible flap formed with a hole is slid as far up the cup as possible, it will immediately fall away from the cup when released. However, when the flap is weighted to one side and lies with its plane inclined to the central axis of the up, it is found that the cup becomes jammed m the hole in the flap. Surprisingly, despite the fact the cup tapers downwards, this jamming action is capable of supporting the weight of a bag of potato chips or a hamburger.
In US-A-4 , 620, 631 the carrying means constituted by the flexible strip surrounding the cup are used to grip the cup and if the containers are not held firmly, the cup must be gripped more firmly and this can result m the cup being squeezed excessively causing its contents to spill. By contrast, in the present invention, once the cup has been slipped into the hole of the food container the cup can be carried in the normal way and the food container will automatically hang from it. The edge of the hole and the
outer surface of the cup form a self-tightening coupling that prevents the food container from slipping downwards relative to the cup.
As the purchased food is normally hot whereas the drink may be cold or even iced, it is preferable to be able to maintain a space between the food container and the cup as they are being carried. To this end, the container may conveniently be provided with a pair of spacer wings to straddle the sides of the cup, so that cup may be gripped through the wings. As well as keeping the food 'and the drink out of thermal contact with one another, such wings make it easier to carry the cup if it contains a hot drink as the wings afford additional thermal insulation. The wings act primarily as spacers and are not replied upon to support the weight of the container on the cup.
Alternatively, the container may be provided with a pair of wings that can be interlocked with one another to form a spacer ring between the cup and the container.
It is preferred that the container should be formed of paperboard or card, but it is alternatively possible for it to be formed of a plastics material.
Brief description of the drawings
The invention will now be described further, by way of example, with reference to the accompanying drawings, in which:
Figure 1 is a rear view of a container of the invention, and
Figure 2 is a perspective view of the container of Figure 1 when coupled to a cup so that they may together be carried in one hand.
Detailed description of the preferred embodiments
In Figure 1, there is shown a food container 10 having a food compartment 20 of any desired shape. A flap 12 having a hole 14 extends upwards from the food compartment 20. Two further wings 16 extend laterally from the food compartment 20. The flaps may either be formed from the same blank as the compartment 20 or they may be formed separately and later secured to the compartment 20, for example by means of an adhesive.
In use, the food container 10 is coupled to a conventional paper cup 18 in the manner shown in Figure 2. The flap 12 is folded over and the paper cup 18 is inserted into the hole 14. The wings 16 straddle the cup 18 and to carry the cup, it is gripped between the two wings 16. The wings 16 act as spacers to keep the food compartment 20 distant from the cup 18, which is important as the food and the drink are often at different temperatures. If the drink is hot, the wings 16 also act as thermal insulation.
Because the wings 16 are not relied upon to support the weight of the container 10, it is possible to form the wings 16 to that their ends simply interlock with one another. In this way, when interlocked, the spacer flaps may form a cylinder or ring disposed between the food compartment 20 and cup 18 to keep the two apart.
Of course, instead of a single food compartment 20, the container may have two or more but in practice even one compartment is sufficient to allow a person to eat food from the compartment 20 and drink from the cup 18 using a straw, while leaving one hand free to hold a hamburger.
It has been found m practice that the engagement of the cup 18 within the hole 14 holds the food container
firmly in place in relation to the cup and that one can suspend the food container from the cup.
