Preferred embodiments of the present invention will be described in detail below based on the drawings.

(overall structure)
As shown in FIG. 1, the beverage cup is comprised of a main body cup 1 and an inner cup 2 each having an open top, and a lid 3 that covers the opening. In the case of the illustrated embodiment, the main body cup 1 and the inner cup 2 are formed in a round shape with a circular cross section, but they may be square in shape.

The main body cup 1 is formed of a heat insulating structure 4 having a vacuum heat insulating structure with an inner and outer double wall formed by an inner container 4a and an outer container 4b made of metal such as stainless steel, and the lid body 3 is attached to the body cup 1. It is provided with an opening edge 5 for opening. At this time, in the case of the illustrated embodiment, a handle 6 is provided on the side of the main cup 1, so that the main cup 1 can be used as a mug.

The inner cup 2 is made of plastic that can be heated in a microwave oven, and includes a cup portion 7 that is removably inserted into the main cup 1, and a cup portion 7 that is inserted above the opening edge 5 of the main cup 1 when inserted. The belt-shaped peripheral wall 8 is provided to form an opening edge 9 on which the lid 3 is attached.

The band-shaped peripheral wall 8 has a larger diameter than the cup portion 7, so that a tapered wall 10 whose diameter gradually increases from the cup portion 7 to the band-shaped peripheral wall 8 is formed. A cup packing 11 that protrudes as a protrusion is provided around the outer peripheral surface of the cup portion 7.

The lid 3 is made of plastic that can be heated in a microwave oven, and includes a plug 12 and a flange 13 projecting from the top of the plug 12. A lid packing 14 protruding from the top is provided around the periphery. In the illustrated example, the flange 13 has a knob 13a extending therefrom.

(Usage form by combination)
Therefore, the beverage cup has a first form (FIGS. 2 to 5) in which the lid body 3 is attached to the opening edge 5 of the main cup 1 and is closed, and a cup part 7 of the inner cup 2. A second embodiment (FIGS. 6 to 9) is selectively used by attaching and closing the lid 3 to the opening edge 9 of the band-shaped peripheral wall 8 of the inner cup 2 while inserted into the main body cup 1. It is possible to configure. Hereinafter, these usage patterns will be explained together with the preferred configuration of each part.

(First form)
When the first form shown in FIGS. 2 to 5 is selected and used, the beverage cup can be used in the same manner as a conventional mug with a heat-insulating structure. At this time, since the inner cup 2 is not required, it may be stored separately.

As shown in FIG. 3, with respect to the inner diameter d1 and outer diameter d2 of the opening edge 5 of the main body cup 1, the lid body 3 is formed so that the outer diameter D of the plug part 12 satisfies d1≧D, The plug portion 12 is vertically disposed downward from the flange 13 with a length L.

As a result, as shown in FIG. 5, when the plug part 12 of the lid body 3 is pushed and inserted into the opening edge 5 of the main cup 1, the flange 13 comes into contact with the upper end of the opening edge 5, and at this time, the lid packing 14 is brought into elastic contact with a packing receiving surface 15 formed on the inner peripheral surface of the opening edge 5. Thereby, the main body cup 1 is sealed in a closed state with the lid 3, and the lid 3 is fixed in the closed state.

The beverage cup in the first configuration can be used in the same manner as a conventional mug with an insulating structure. That is, for example, a hot beverage such as coffee or tea can be poured into the main body cup 1 and can be drunk while being kept warm. Alternatively, a beverage such as a cold soft drink can be poured into the main body cup 1 and can be drunk while being kept cold. At that time, by closing the lid with the lid 3, it is possible to maintain the heat retention state or the cold retention state.

(Second form)
When selecting and using the second form shown in FIGS. 6 to 9, the beverage cup is produced by inserting the cup part 7 of the inner cup 2 into the main body cup 1, and placing the band-shaped peripheral wall 8 on the opening edge 5. It is used in this state.

As shown in FIGS. 7 and 9, when the cup part 7 of the inner cup 2 is pushed and inserted into the main body cup 1, the step part 8a formed at the lower end of the band-shaped circumferential wall 8 of the inner cup 2 touches the opening edge of the main body cup 1. At this time, the cup packing 11 comes into elastic contact with a packing receiving surface 15 formed on the inner circumferential surface of the opening edge 5. As a result, the inner cup 2 is coupled to the main body cup 1 in a fixed state without wobbling.

As shown in FIG. 7, the inner diameter t1 and the outer diameter t2 of the band-shaped peripheral wall 8 of the inner cup 2 are formed so that t1≧D with respect to the outer diameter D of the stopper 12 in the lid body 3. Moreover, the depth T of the inner circumferential portion of the band-shaped circumferential wall 8 formed at the inner diameter t1 is formed so that T≧D with respect to the length L of the plug portion 12.

Thereby, the opening edge 9 formed by the band-shaped peripheral wall 8 of the inner cup 2 can be covered with the lid body 3. As shown in FIG. 9, when the plug part 12 of the lid body 3 is pushed into the opening edge 9 of the inner cup 2, the flange 13 comes into contact with the upper end of the opening edge 9, and at this time, the lid packing 14 opens. It comes into elastic contact with a lid packing receiving surface 16 formed on the inner peripheral surface of the edge 9. As a result, the inner cup 2 is sealed in a closed state with the lid 3, and the lid 3 is fixed in the closed state.

The beverage cup of the second form can be used in the same manner as a conventional mug with a heat insulating structure by storing a beverage in the inner cup 2 coupled to the main body cup 1. That is, for example, a warm beverage such as coffee or tea can be poured into the inner cup 2 and drunk while being kept warm. Alternatively, a beverage such as a cold soft drink can be poured into the inner cup 2 and kept cold. At that time, by closing the lid with the lid 3, it is possible to maintain the heat retention state or the cold retention state.

Unlike the case of the first form, the beverage cup of the second form can be heated to an appropriate temperature by taking out the inner cup 2 from the main cup 1 when the temperature of the beverage stored in the inner cup 2 changes. Or it can be cooled. When the hot beverage has cooled down, the inner cup 2 taken out from the main cup 1 can be heated in a microwave oven and inserted into the main cup 1 again for drinking. At this time, heating with a microwave oven is possible with the lid 3 attached to the inner cup 2, and the heating efficiency is high.

On the other hand, when a cold drink such as a soft drink becomes lukewarm, the inner cup 2 taken out from the main cup 1 can be cooled in a refrigerator, and then inserted into the main cup 1 again for drinking.

Alternatively, you can optionally pour a beverage that has been brought to room temperature into the inner cup 2 and warm it up by heating it in a microwave oven, or cool it in a refrigerator to reach the desired temperature, and then insert the inner cup 2 into the inner cup 2. By inserting and coupling it into the main body cup 1, it can also be used as a second form of drinking cup.
