Description

CUPPING DEVICE
BACKGROUND OF INVENTION

1. Field of Invention The present invention relates to a paper cup and, more particularly, to a cupping device including a paper cup equipped with an insulating unit.
2. Related Prior Art Many drinks such as coffee, juice and tea are contained in disposable containers and sold. In consideration of convenience, drinks are often contained in paper cups. A paper cup includes an upper edge that is rolled, pressed and then coated with a plastic layer. Thus, the upper edge of the paper cup is made with a multi-layered configuration for providing an adequate rigidity. The processing of the upper edge of the paper cup is however complicated and therefore expensive.

Moreover, paper cups are poor in insulating and actually not good for containing hot drinks. That is, heat is easily transferred to a user's hand from a hot drink via a paper cup. Thus, a user feels hot in his or her hand and might get burnt in the worst scenario. Moreover, heat is easily transferred to the environment from a hot drink via a paper cup. Thus, the drink gets cold easily. On the other hand, heat is easily transferred to a cold drink from the environment through a paper cup. Thus, the cold drink gets hot easily. As discussed above, the drink, hot or cold, loses its favor soon after it is contained in the paper cup. Moreover, paper cups are weak generally and could be deformed easily. In that case, a hot or cold drink could be spilt or leaked easily. A spilt hot drink could burn a user in the hand.

To overcome the foregoing problems, there has been devised at least one cupping device including a paper cup located in a paper sleeve, with an i insulating space defined between the paper cup and the paper sleeve. The paper cup includes a tubular element attached to a bottom element by adhesion. The paper sleeve includes an internally retroflex lower edge.
Thus, transfer of heat is not easy because of the insulating space. Moreover, the paper cup is reinforced by the paper sleeve. The use of the conventional cupping device is however not without any problem. An upper edge of the paper sleeve is in contact with an upper edge of the paper cup. In fact, an upper portion of the paper sleeve is located very close to an upper portion of the paper cup so that the insulating space is thin near the upper portion of the paper sleeve. Hence, the insulating effect of the insulating space is poor near the upper portion of the paper sleeve. However, the user tends to hold the upper portion of the paper sleeve while drinking the hot drink from the cupping device and feels hot or might get burnt in the worst scenario. Moreover, heat is transferred to the environment from the hot drink or transferred to the cold drink from the environment at a considerable rate.

When a paper cup is used to contain hot coffee or tea, a paper sleeve is often provided around the paper cup and a cap is often provided on the paper cup for insulating. The cap has to be removed from the paper cup so that sugar and/or coffee mate can be added into the coffee or tea. Generally, a user holds the paper sleeve against the paper cup with the left hand and removes the cap from the paper cup with the right hand. The user has to hold the paper sleeve against the paper cup really hard with the left hand so that he or she can remove the cap from the paper cup. Otherwise, the user might remove the cap and the paper cup from the paper sleeve. The user however might squeeze the paper cup and spill the hot coffee or tea from the paper cup, and this is both a waste and danger.

The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.
