Description
- 1. Field of Invention
- The present invention relates to a paper cup and, more particularly, to a cup assembly including a paper cup located in a paper sleeve, with an insulating space defined between the paper cup and the paper sleeve.
- 2. Related Prior Art
- Many drinks such as coffee, juice and tea are contained in disposable containers and sold. In consideration of convenience and cost, many drinks are contained in paper cups. Paper cups are however 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 cup assembly including a paper cup located in a paper sleeve, with an insulating space defined between the paper cup and the paper sleeve. The paper cup includes a tubular body 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 cup assembly 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 cup assembly 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.
- 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.
- The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.
- It is the primary objective of the present invention to provide an inexpensive, insulating cup assembly.
- To achieve the foregoing objective, the cup assembly includes two sleeves, a bottom element, a ring and bosses. The sleeves are made of paper while the ring and bosses are made of a plastic material. The first sleeve is made with a lower edge and an upper edge. The bottom element is attached to the lower edge of the first sleeve. The ring is formed on the upper edge of the first sleeve. The bosses are formed on the first sleeve against the ring. The second sleeve is made of paper with a lower edge and an upper edge. The lower edge of the second sleeve is located against the bosses as the second sleeve is provided around the first sleeve. Thus, an adequate insulating space is defined between the first and second sleeves.
- In an aspect, the first sleeve is made of PE-coated paper.
- In another aspect, the mouthpiece and the bosses are provided on the upper edge of the first sleeve by injection molding.
- In another aspect, the mouthpiece and the bosses are made of a conventional plastic material, a biodegradable plastic material or a bio-plastic material.
- In another aspect, the bottom element is made of paper. The lower edge of the first sleeve is an internally retroflex edge engaged with an edge of the bottom element.
- In an alternative aspect, the bottom element is made of a plastic material. The bottom element is made of a conventional plastic material, a biodegradable plastic material or a bio-plastic material. The bottom element includes two annular grooves for receiving the first and second sleeves so that the insulating space is adequate and constant from top to bottom.
- In another aspect, the cup assembly further includes a ring made of plastic between the first and second sleeves near the lower edges so that the insulating space is adequate and constant from top to bottom.
- In another aspect, the lower edge of the second sleeve is an internally retroflex edge in contact with the first sleeve so that the insulating space is adequate and constant from top to bottom.
- In another aspect, the cup assembly further includes an annular lip extending from the mouthpiece so that an annular gap is defined between the annular lip and the bosses for receiving the upper edge of the second sleeve.
- In another aspect, the mouthpiece, the bosses and the annular lip are provided on the upper edge of the first sleeve via injection molding.
- In another aspect, the mouthpiece, the bosses and the annular lip are made of a conventional plastic material, a biodegradable plastic material or a bio-plastic material.
- In another aspect, the cup assembly further includes a thermal foaming layer provided between the first and second sleeves.
