DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] The above and other objects, features and advantages of this disclosure will become apparent from the following detailed description taken with the accompanying drawings. It is noteworthy that the drawings are intended for illustrating the present invention only, but not for limiting the scope of the invention, and the drawings are not necessarily drawn according to the actual shape, size or proportion of the device.

[0028] The present invention is directed to a cup-shaped container. In an embodiment used for describing the present invention and related components of the invention and the accompanying drawings used for illustrating the specific embodiment, the terms “front”, “rear”, “left”, “right”, “top”, “bottom”, “up”, “down”, “horizontal”, and “vertical” are used for the facilitating the description of the present invention only, but not intended for limiting the present invention or limiting the position or spatial direction of the components. The size specified in the drawings and the specification can be changed or modified according the design and requirement of the specific embodiment of the present invention without departing from the scope of the present invention.

[0029] With reference to FIGS. 6 and 7 for the detailed assembly of a cup-shaped container of the present invention, the cup-shaped container comprises a cup body (50), and the cup body (50) of this embodiment is made of polyethylene terephthalate (PET) and substantially in a cylindrical shape, and the cup body (50) has a first end (501) and a second end (502), and a hollow chamber (51) is formed in the interior between the first and second ends (501, 502) of the cup body (50), and when the cup body (50) is standing, the chamber (51) has a cup opening (52) with an upwardly opened opening and configured to be relative to the first end (501) of the cup body (50), a cup rim (55) defined at an inner periphery of the cup opening (52), and the cup body (50) has an outer diameter increasing gradually from the first end (501) to the second end (502) and curving downwardly and stopped at the second end (502), and an inwardly concave portion (56) at the middle of the second end (502) of the cup body (50), and the second end (502) has a circular abutting surface (57) formed at the periphery of the inwardly concave portion (56) periphery and provided for erecting the cup body (50) from a plane, and the circular abutting surface (57) has a width of 0.1 mm˜0.5 mm, so that two adjacent cup bodies (50) can be stacked with respect to each other by the circular abutting surface (57) of the second end (502).

[0030] The cup body (50) has an outwardly protruding flange (58) formed at an outer periphery of the cup opening (52), and the flange (58) is protruded from an outer wall of the cup body (50) by a distance of 0.05˜0.3 mm in this embodiment. In addition, the cup body (50) has a flat attachment surface (59) formed at tops of the cup rim (55) and the flange (58), and the flat attachment surface (59) has a width of 0.1 mm˜0.5 mm in this embodiment to allow two adjacent cup bodies (50) to be stacked with each other by using the flat attachment surface (59) of the first end (501) as shown in FIGS. 8 and 9, so that two adjacent cup bodies (50) can be stably stacked with each other.

[0031] The aforementioned components are assembled into a simple-structured and stably stackable cup-shaped container.

[0032] In a practical application of the present invention as shown in FIGS. 6, 7 and 8, the cup body (50) can be put on any plane such as a tabletop by using the circular abutting surface (57) of the second end (502), so that the cup body (50) can be placed stably without the risk of being dumped arbitrarily. When there is a need to stack the cups for storage, the cup openings (52) at the first end (501) of each cup body (50) of two adjacent cups are aligned, and the cup rim (55) of the cup opening (52) and the flat attachment surface (59) of the flange (58) are aligned and attached as shown in FIGS. 8 and 9, so that two cup bodies (50) can be stacked with each other without causing any slipping, dumping or tilting.

[0033] In the structural design described above, the present invention utilizes the externally expanded flange (58) formed by an outer periphery of the cup opening (52), so that the cup body (50) forms a substantially planar flat attachment surface (59) at a top periphery of the cup opening (52), and two adjacent cup bodies (50) can be stacked with each other. When the cup body (50) of the present invention is stored, the cup body (50) has a better and more stable stacking effect. Compared with the prior art, the invention achieves the effects of lowering the manufacturing cost effectively and improving the practicality of the cup-shaped container significantly.

[0034] In summation of the description above, it is understood that the present invention is an innovative creation capable of overcoming the drawbacks of the prior art and improving the effect significantly, and the invention complies with patent application requirements, and thus is duly filed for patent application.
