CUP STRUCTURE
A cup structure comprises an inner cup and an outer cup. A groove is formed on an outer surface of the inner cup and concaved from the outer surface to an inner surface. The inner cup is completely or partly wrapped by the outer cup. The groove of the inner cup and a portion of the outer cup form a fluid channel. Suction holes are formed at two ends of the fluid channel. Thereby, the user can suck the material inside the cup structure. Further, the cup structure can be disassembled conveniently for cleaning.
The present invention relates to a cup structure, particularly to a cup structure having a fluid channel.
2. Description of the Prior ArtWhile a hand-shaken iced drink (such as a cup of pearl milk tea) is sold in conventional beverage shops, the drink is sealed by a sealing machine. When intending to drink it with a straw, the user uses the straw to penetrate the sealing film and then sucks the drink with the straw. Then, the straw is thrown into a recycling tank after drinking. However, too many straws are abandoned in the environments and oceans and the abandoned straws are hard to be reused because of recycling difficulties. Thus, the marine pollution, plastic waste and other problems are caused. Therefore, the government begins to limit the use of disposable straws.
Accordingly, the manufacturers are eager to develop a cup structure, which is environment-friendly and easy to carry, use and clean, and which is also user-friendly, i.e. allows users not to change the original usage habit as much as possible.
SUMMARY OF THE INVENTIONThe present invention provides a cup structure, wherein a fluid channel is formed inside the cup structure, and wherein the fluid channel has suction holes at two ends, whereby the user may conveniently suck the material inside the cup structure, and whereby the cup structure may be easily disassembled for cleaning.
In one embodiment, the present invention proposes a cup structure, which comprises an inner cup and an outer cup. The inner cup has an inner surface, an outer surface and a first opening. A first groove is formed on the outer surface, concaved from the outer surface to the inner surface. The outer cup receives the whole inner cup or a portion of the inner cup. The first groove and the outer cup jointly form a fluid channel. The first groove extends from the first opening to a cup bottom of the inner cup. A first suction hole is formed at the first opening; a second suction hole is formed on the inner surface and at the cup bottom of the inner cup. The first suction hole, the first groove, a portion of the outer cup and the second suction hole cooperate to form the fluid channel.
Below, embodiments are described in detail with the attached drawings to make easily understood the objectives, technical contents, characteristics, and accomplishments of the present invention.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, in which:
The present invention provides a cup structure, which comprises an inner cup and an outer cup. The inner cup has a groove formed on an outer surface thereof and concaved from the outer surface to an inner surface thereof. The outer cup receives the inner cup completely or partly. The groove of the inner cup and a portion of the outer cup structure form a fluid channel.

The diameter of the fluid channel 130 may be designed according to the requirement of the customer. In other words, the diameter of the fluid channel 130 may be varied according to drinks and users. For example, the fluid channel 130 adopts an ordinary diameter for ordinary users, an ordinary or smaller diameter for children, a larger diameter for a thick drink or a drink with another food, such as red beans, green beans, coconut jelly, tapioca pearls, taro rice balls, sarcocarp, vegetarian gelatin, sweet potato noodles, etc. The present invention does not constrain that the fluid channel 130 must have the shapes shown in

In one embodiment, the hardness of the material of the main cup body 210 is higher than the hardness of the material of the cup seat body 220. The cup seat body 220 may be made of an elastic material, which may be but is not limited to be a material selected from a group including plastics, silicones, rubbers, resins, glass, metals, ceramics, paper, wood, plant fibers, natural minerals, and composite materials. The present invention does not particularly limit the material of the main cup body 210. In principle, the material of the main cup body should be harder than the material of the cup seat body so that the user can suck conveniently. The elastic material of the cup seat body 210 not only can increase the frictional force between the cup seat body and the main cup body but also can provide slip-proof and heat-insulating functions. Further, the elastic material enables users to separate the cup seat body 220 from the main cup body 210 easily and thus makes users clean the main cup body and the cup seat body conveniently.
Accordingly, the present invention provides a cup structure, wherein two ends of the fluid channel function as the suction pipe, whereby the user can suck the material contained in the cup structure conveniently and easily. The cup structure of the present invention may be fabricated to be a non-disposable environment-friendly cup or a disposable cup that is usually used by beverage shops. If the cup structure of the present invention is fabricated to be a non-disposable cup, it can be washed conveniently. As long as the inner cup is drawn out, the inner cup, the groove and the outer cup can be washed easily. It is obvious that washing the cup structure of the present invention is easier than washing an ordinary environment-friendly straw. Further, the inner cup structure of the present invention can be split into two pieces, whereby they can be stacked conveniently. Furthermore, the protrudent handle member on the cup structure of the present invention not only can be designed to a cup lug but also can be designed to have different patterns, whereby to increase the holding area as well as to enhance the esthetics of the cup structure and promote the recognizability of the product.
In conclusion, the present invention proposes a cup structure, which is characterized in having a fluid channel formed inside the cup structure and using two ends of the fluid channel as suction holes, whereby the user can suck or drink the material inside the cup structure conveniently, and whereby the cup structure can be disassembled for cleaning easily.
The embodiments has been described above to demonstrate the technical thoughts and characteristics of the present invention and enable the persons skilled in the art to understand, make, and use the present invention. However, these embodiments are only to exemplify the present invention but not intended to limit the scope of the present invention. Any equivalent modification or variation according to the spirit of the present invention is to be also included by the scope of the present invention.
