The technical features, contents, and advantages of the present invention, as well as the advantages thereof, can be understood by the present inventors, and the present invention will be described in detail with reference to the accompanying drawings. The subject matter is only for the purpose of illustration and description. It is not intended to be a true proportion and precise configuration after the implementation of the present invention. Therefore, the scope and configuration relationship of the attached drawings should not be interpreted or limited. First described.

Please refer to FIG. 2 to FIG. 4 , which are respectively a first schematic diagram, a second schematic diagram and a third schematic diagram of the first embodiment of the composite cup structure of the present invention, and please refer to FIG. 5 and FIG. 6 together. They are respectively a first schematic diagram and a second schematic diagram of a second embodiment of the composite cup structure of the present invention. One of the features of the present invention is that the composite cup structure is a double-layer cup structure, wherein one cup body can be stacked in a relatively simple manner in another cup body, and the user can hold the hand-held cover when in use. In the outer cup, the drink is filled in the inner cup, and the space between the two cups can be used to achieve the thermal insulation effect, so as to avoid the hot drink filled by the user. Another feature of the present invention is that a part of the structure between the two cups is closely attached to each other, so that when the beverage is filled in the inner cup and exposed, the liquid can be prevented from slipping to the two cups. between.

In detail, as shown in FIGS. 2 to 6, the composite cup structure of the present invention comprises an outer cup 10 and an inner cup 20. The inner wall of the cup of the outer cup 10 is formed with a first curved portion 12 having a vertical surface near the outer cup opening 11. The end edge of the cup opening 21 of the inner cup 20 forms a contact portion 22, and the contact is formed. The portion 22 abuts against the first meandering portion 12 of the outer cup 10, whereby the inner cup 20 can be disposed in the inner portion of the outer cup 10, and the cup bottom and the outer cup of the inner cup 20 The bottom of the body 10 forms a gap space. Preferably, the distance A between the first meandering portion 12 and the contact portion 22 to the cup cup 11 outside the outer cup 10 is 11 mm to 16 mm. When the user is drinking, the lips can indirectly feel the temperature of the drink, and the user is prevented from scalding the lips due to overheating of the drink, but not limited thereto.

In the above, the first meandering portion 12 of the cup body 10 of the first embodiment may be designed as a class structure. As shown in FIGS. 3 and 4, the class structure 121 may have a concave shape, or It can be designed to be planar, and the contact portion 22 of the inner cup 20 can be designed to abut against the level surface 121. The first meandering portion 12 of the second embodiment is designed as a ring groove. As shown in FIGS. 5 and 6, the outer cup 10 can be fitted by the first bent portion 12 in the shape of a ring groove. The contact portion 22 is for fixing the inner cup 20.

Further, the outer cup body 10 is formed with a first abutting portion 13 below the first bent portion 12, and the outer wall of the inner cup body 20 further forms a second abutting portion 23 below the contact portion 22, The second bonding portion 23 is closely attached to the first bonding portion 13 of the outer cup 10, whereby the filled beverage can be prevented from dripping between the inner cup 20 and the outer cup 10. The length of the section C of the first bonding part 13 and the second bonding part 23 may be 1 mm. Up to 4mm, but not limited to this.

In addition, the outer cup body 10 is further formed under the first abutting portion 13 to form a second bent portion 14 , and the inner cup body 20 is coupled to the second abutting portion 23 to form a buckle portion 24 . The buckle portion 24 is fastened to the second bent portion 14 , whereby the fixing strength between the inner cup 20 and the outer cup 10 can be improved to prevent the inner cup 20 from slipping out of the outer cup 10 when the user drinks the beverage. . Preferably, the distance B between the first bent portion 12 and the contact portion 22 to the position where the buckle portion 24 and the second bent portion 14 are offset is less than 10 mm, which contributes to the outer cup 10 and the inner cup. 20 increases in strength when used, but is not limited to this.

The cup body 10 and the inner cup body 20 are preferably made of plastic, paper or foamed material, and the outer cup body 10 and the inner cup body 20 are made of a transparent material. Or made of dyed cup material. Further, the bottom of the cup of the outer cup 10 may be provided with a perforation 15 for discharging the gas generated by the heat between the outer cup and the inner cup, so that the pressure between the inner cup and the outer cup is balanced. Avoid wrinkles and deformation of the cup.

Looking at the above, it can be seen that the combination cup structure of the present invention has achieved the desired effect under the prior art, and is not easily understood by those skilled in the art. Moreover, the present invention has not been disclosed before the application, and Its progressive and practical nature has been in line with the patent application requirements, and the patent application has been filed according to law.
