Abstract
A paper cup assembly includes a paper cup 10 with a bottom piece connected to the lower end thereof and the cup has an open top. A lip portion made of bio-degradable plastic material is formed along the open top by way of injection molding, heat-pressing or high-frequency wave welding. Multiple protrusions are formed on the outside of the cup when forming the lip portion. The cup has a positioning portion and the isolation collar is mounted to the cup and the top portion of the isolation collar is connected to the positioning portion. The lower portion of the isolation collar is fixed to the cup. A gap is defined between the whole isolation collar and the cup. When used to a deep cup, the protrusions are helpful for isolating the heat from the cup.
Description
- 1. Field of the Invention
- The present invention relates to a paper cup assembly, and more particularly, to a paper cup with heat isolation collar mounted thereto.
- 2. Background of the Invention
- A conventional beverage cup for take-out generally is made by paper which cannot isolation temperature of the beverage so that the user cannot hold the cup because the high temperature transferred to the user's hand. Besides, the beverage soon becomes cold for the same reason and this affects the taste of the beverage. Taiwan Utility Patent No. M379573 discloses a paper cup as shown in
FIG. 1 and includes a cup with a bottom piece connected to the underside of the cup, and an isolation piece located on outside of the cup. The isolation piece has a connection portion and an inner layer which folded downward from the connection portion. A space is defined between the outside of the cup and the isolation piece. By the isolation piece, the structural strength of the cup is reinforced and the space cuts off the heat transferring to the user's hand. - It is noted that the conventional isolation piece is connected to the lower edge of the open top of the cup so that the top portion of the isolation piece is almost in contact with the cup. However, when using the beverage in the cup, the users usually hold the top portion of the cup so that the user can feel the high temperature at the top portion of the cup because there is no gap between the cup and the top portion of the isolation piece. Even if there is a gap, when the length of cup is long enough, the isolation piece cannot bear the pressure applied to the isolation piece from the user so that the user still contact the cup and feel the temperature.
- The present invention intends to provide a paper cup with an isolation collar which improves the shortcomings of the conventional isolation piece.
- The present invention relates to a paper cup assembly and comprises a paper cup with a bottom piece connected to the lower end thereof and the cup has an open top. A lip portion made of bio-degradable plastic material is formed along the open top by way of injection molding, heat-pressing or high-frequency wave welding. Multiple protrusions are formed on the outside of the cup when forming the lip portion. The cup has a positioning portion and the isolation collar is mounted to the cup and the top portion of the isolation collar is connected to the positioning portion. The lower portion of the isolation collar is folded inward and fixed to the cup. A gap is defined between the whole isolation collar and the cup. When used to a deep cup, the protrusions are helpful for isolating the heat from the cup.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
-
FIG. 1 is a cross sectional view of the conventional paper cup; -
FIG. 2 is a perspective view to show the paper cup assembly of the present invention; -
FIG. 3 is an exploded view to show the paper cup assembly of the present invention; -
FIG. 4 is a cross sectional view of the paper cup assembly of the present invention; -
FIG. 5 is a cross sectional view to show another embodiment of the paper cup assembly of the present invention, and -
FIG. 6 shows that the paper cup assembly of the present invention has a plastic bottom piece. - Referring to
FIGS. 2 to 6 , the paper cup assembly of the present invention comprises apaper cup 10 with alip portion 20, and anisolation collar 30 which is mounted to thecup 10. - The
cup 10 is made by rolling a piece of paper board and abottom piece 11 is connected to the lower end thereof and thecup 10 has anopen top 12. Thelip portion 20 is formed along theopen top 12. - The
lip portion 20 is an annular portion and made of plastic material formed along theopen top 12 by way of injection molding, heat-pressing or high-frequency wave welding. Thecup 10 has apositioning portion 21 defined in the underside of thelip portion 20.Multiple protrusions 22 are integrally formed on the outside of thecup 10 when forming thelip portion 20. Theisolation collar 30 is mounted to thecup 10 and a top portion of theisolation collar 30 is connected to thepositioning portion 21. Theprotrusions 22 are in contact with theisolation collar 30 when a user holds theisolation collar 30. - The top portion of the
isolation collar 30 is engaged with thepositioning portion 21 of thelip portion 20 by way of gluing or heat-welding. The lower portion of theisolation collar 30 is folded inward and fixed to the outside of thecup 10 by way of gluing or heat-welding. Therefore, agap 41 is defined between the outside of thecup 10 and the inside of theisolation collar 30. As shown inFIGS. 4 and 5 , when fixing the lower portion of theisolation collar 30 to the cup, because the top portion top portion of theisolation collar 30 is engaged with thepositioning portion 21 of thelip portion 20, so that the lower portion of theisolation collar 30 is easily decided to be connected to the position of thecup 10, either close to the lower end of the cup or in flush with the underside of thecup 10. - Furthermore, as shown in
FIG. 6 , thebottom piece 11 is made by plastic material and integrally formed with the cup by way of injection molding, heat-pressing or high-frequency wave welding. Thebottom piece 11 has apositioning groove 111 when thebottom piece 11 is made. The lower portion of theisolation collar 30 is engaged with thepositioning groove 111. - By the top portion of the
isolation collar 30 engaged with thepositioning portion 21 so that the inside of theisolation collar 30 does not contact the cup to affect the isolation feature. When theisolation collar 30 is used to adeep cup 10, theprotrusions 22 reinforce the structural strength of theisolation collar 30. The inside of the isolation collar 30 contacts theprotrusions 22, rather than thecup 10, so as to have better isolation feature. - While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
