Description
- 1. Field of the Invention
- The present invention relates to a heat-resisting drinking cup, and more particularly to a portable coffee cup having radial ribs integrally formed around the external periphery of a cup opening of the cup for preventing the high-temperature heat from being conducted directly to the outside or a handle of the cup.
- 2. Description of the Related Art
- Drinking coffee or tea becomes an indispensable part of life to coffee or tea drinkers. At an early stage, people usually drink coffee or tea in restaurants or at home, but the style of our living has changed, and chained coffee shops such as “Starbucks” arise. People change their dining and drinking habits, and take-out coffee is a good example of these changes.
- Referring to
FIGS. 1 and 2 for a traditional disposable drinking cup used for take-out coffee, the drinking cup is apaper cup 10, and thus ajoint 11 is disposed at the edge of a cup opening, andsuch joint 11 is adhered by glue. Since thepaper cup 10 contains a hot drink such as coffee or tea and its temperature is very high, therefore the glue at thejoint 11 may be melt slowly within a few minutes after the adhesion, and coffee may leak from the position of thejoint 11. Furthermore, the internal edge of thepaper cup 10 is coated with a layer of water-resistingfilm 12 for preventing water from moistening the whole paper cup or softening the paper cup. Although adisposable paper cup 10 is convenient to use, the surface of thedisposable paper cup 10 will become very hot after a few seconds after the hot water at 95° C. is poured into the cup, since the temperature at the external surface of cup is decreased by 5° C. only and remained at a high temperature of 90° C. after the heat is dissipated to the external surface of the disposable paper cup. In addition, the external surface of the disposable paper cup is a smooth surface and the external surface of the paper cup touched by a user's palm is almost equal to the whole thermally conducting area. When a user drinks a hot drink, it is quite often that the user gets burned by the hot drinking cup. Since the thermally conducting area is too large, therefore heat may be dispersed to the outside easily, and the cup no longer can provide a good heat preserving function anymore. - Referring to
FIG. 3 for a perspective view of a conventional disposableplastic cup 20, theplastic cup 20 is formed by an injection molding process, and thus it does not have ajoint 11 as in thepaper cup 10 or a risk of leaking. However, the thermal insulating effect of theplastic cup 20 is not as good as that of thepaper cup 10, and thus a user's hand may get burned easily. Although theplastic cup 20 may have a plurality ofcircular lines 21 disposed at the periphery around the middle of the cup, thecircular lines 21 are just shallow lines provided for users to hold the cup by a hand. The user's hand still will touch the surface of the cup body, and the practical heat-resisting effect is poor. Therefore, thecircular lines 21 is provided simply for improving the friction at the surface of the cup and facilitating users to hold the cup by a hand. - Although the conventional
disposable paper cup 10 andplastic cup 20 are convenient, thesecups cups - Therefore, it is a primary object of the invention to provide an integral heat-resisting structure of a disposable drinking cup, wherein the heat-resisting structure is integrally formed and has no joint or a risk of causing a leaking problem.
- Another objective of the present invention is to install radiating fins at the external periphery of a cup opening of the disposable plastic cup, so as to prevent a user's hand from touching the surface of the cup body and enhance the effect of preventing a user's hand from getting burned.
- A further objective of the present invention is to use the heat-resisting radiating fins to improve the friction for a user's hand to hold the cup, so as to provide a more secured and convenient grip of the cup.
- In order to achieve the above-mentioned objectives, several tens of radial ribs are integrally formed at the bottom of the cup lip of the cup opening, and the
radial ribs 40 are extended at least 1.5 mm from the surface of the cup body, and an interval D between two adjacent radial ribs falls within a range of 3˜5 mm. Meanwhile, the height of each radial rib is less than 10 mm measured downward from the cup lip of the cup opening. In this way, a plurality of radiating fins are formed around the external periphery of the cup opening. In addition, the high-temperature heat can be prevented from being conducted directly to the outside or a handle of the cup. -

FIG. 4 for a perspective view of a preferred embodiment of the present invention, the invention comprises: acup body 30 formed by a plastic injection molding process and made of a polypropylene (PP) material or a polyethylene (PE) material. Thecup body 30 has a cup opening disposed at the top of thecup body 30 and folded outward to form acup lip 31 around the cup opening, and these elements constitute the structure of a general plastic cup. - The present invention is characterized in that several tens of
radial ribs 40 are integrally formed at the bottom of thecup lip 31 of the cup opening as shown inFIGS. 5 and 5A , and theradial ribs 40 are extended at least 1.5 mm from the surface of thecup body 30, and an interval D between two adjacentradial ribs 40 falls within a range of 3˜5 mm. The results of experiments show that the interval D can prevent a user's palm or finger from touching anexternal surface 33 of thecup body 30 while the user is holding the cup. If the interval D is too large and exceeds 5 mm, then the user's finger may touch theexternal surface 33 of thecup body 30 easily and may even get burned. If the interval D is too small, then the convection of air for dissipating heat within the interval will be decreased, and the heat of the hot drink in thecup body 30 will be conducted to an outer distal surface of the radial ribs 40 (which is the contact surface with the user's finger or palm) through theexternal surface 33. Therefore, it is necessary to have an appropriate interval D between tworadial ribs 40, or else the heat-resisting effect cannot be maximized. - In
FIG. 6 , theradial ribs 40 formed around the external periphery of the cup opening are in the form of radiating fins to provide a holding portion for users to hold. Such arrangement not only provides the heat-resisting effect, but also improves the secured grip of the holding portion. - Referring to
FIG. 7 for a cross-sectional view of the present invention, theradial ribs 40 are disposed at the bottom of thecup lip 31 of the cup opening, and their protruding length falls within the external periphery of thecup lip 31. Referring toFIG. 8 for an enlarged view of a portion ofFIG. 7 , the width W of thecup lip 31 of the cup opening is approximately equal to 5 mm, and the protruding length L of theradial rib 40 preferably falls within the range of 1.5 mm˜4 mm, and anupper edge 41 of theradial rib 40 is connected to the bottom of thecup lip 31 of the cup opening, and its height H is at least 10 mm measured downward from thecup lip 31 of the cup opening, and anedge 42 tapered towards thecup body 30 is preferably formed at the bottom of thecup body 30, so as to improve the comfort and facilitate a user's palm or finger to grip thecup body 30. - The
cup body 30 further includes an outwardly protrudingcircular groove 32 formed on a cup wall corresponding to the bottom of thecup lip 31 of the cup opening. Thecircular groove 32 is provided for preventing the drink in thecup body 30 from spilling out from the cup opening. InFIG. 9 , thecircular groove 32 is provided for embedding and fixing acup cover 50, so that an external edge of thecup cover 50 can be latched simultaneously inside and outside the cup opening to improve the securing effect. - With the foregoing technical measures, the disposable plastic cup of the present invention can overcome the shortcoming of burning a user's hand easily. In addition, the
radial ribs 40 are integrated with thecup body 30 as a whole, and thus there will have no leaking problem of the paper cup. The present invention definitely can overcome the shortcomings of the conventional disposable drinking cup. - With the foregoing technical measures and extensive researches and experiments, the present invention definitely can achieve the expected effects and overcome the foregoing shortcomings of the prior art.
- Many changes and modifications in the above-described embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
