Preferably also the storage container is circular and the recess is circular and coaxial with the second cup.
Preferably also the storage container protrudes from the recess in the cup or in said opposite end of the body to be accessible for removal from the recess.
Preferably also the ends of the body have radially inwardly recessed mountings for the cups.
Preferably also the outer surfaces of the cups provide a smooth extension of the parts of the body to which they are adjacent.
Preferably also the outer surfaces of the cups are stainless steel.
Preferably also the outer surface of the body which is exposed between the cups is stainless steel.
Preferably there is no separate handle for the body, the external surface of the body forming its own integral handle for carrying and to be held "whilst either or both cups are removed from the body or replaced on it.
Alternatively the body is provided with a handle between the mountings for the cups.
Preferably neither cup has any handle. Preferably also the or each cup comprises a liner and an outer skin, the liner providing rigidity for the cup and thermal insulation to protect the consumer's hand from the heat of the liquid in the cup.
Preferably also the skin of each cup is stainless steel.
Preferably also the liner extends beyond the outer skin adjacent the mouth of each cup to provide a decorative rim portion.
Preferably also the body is provided with a plastic sleeve around its central portion between the cups for decorative and/or protective purposes.
Preferably also the decorative rim portion of each cup is of the same appearance as the plastic sleeve.
Preferably also the decorative rim portion of each cup is a smooth extension of the plastic sleeve forming a sophisticated design feature.
Preferably also the sleeve is resilient and soft to the touch to be readily gripped by the user.
Preferably the vacuum- surrounded liquid container comprises a metal inner skin and a metal outer skin between which the vacuum is to be maintained, the skins being fixed together around the opening in the container to its interior.
Preferably also the inner and outer skins are stainless steel. There may be two storage containers of which each is receivable in a recess in the base of each of the two cups.

Figure 10 is a side view of the storage container of Figure 8,
Figure 11 is a sectional view taken along the line 11-11 of Figure 9,
Figure 12 is a sectional view taken along the line 12-12 of Figure 9, and
Figure 13 is a detailed view of the underside of the liquid container.
Referπng initially to Figure 1, in a preferred example of the invention, a vacuum flask 10 comprises a cylindrical body 11, a closure 12 at one end 13 of the body 11, a first cup 14 mounted on said one end 13 of the body 11 over the closure 12, and a second cup 15 mounted on the opposite end 16 of the body 11.
o y 11 (See Flgure 2) is basically made of stainless steel for strength, robustness and style, central section which is a moulding or wrap-around sleeve 17 of a resilient and soft p astic such as a- soft-feel thermoplastic rubber for decoration and/or protection purposes. Just above and below the SIPP P i i + J • t ,. ,, • sιeeve 3 7> tile body is recessed radially inwardly at 18 and provided with coarse screw threads 19 to provide recessed mountings 20 for the cups 14 and 15. In this example the body has no handle, but one may be provided attached to the body 11 between the recessed mountings 20.
The cups 14 and 15 (see Figure 3) each have an outer skin 21 of stainless steel and a liner 22 of plastic material providing rigidity for the cup an / thermal insulation to protect the consumer's hand from the heat of the liquid in the cup. The liner 22 extends at 23 beyond the outer skin 21 adjacent the mouth 24 of each cup to provide a decorative rim portion 25 of the same appearance as the sleeve 17. The junction 26 between the rim portion 25 and the outer skin 21 is a wavy line extending around each cup 14, 15. When the cups 14,15 are screwed on to the threads 19, as shown in Figure 1, the decorative rim portions 25 are a smooth extension of the sleeve 17 forming a sophisticated design feature.
The closure 12 (see Figure 4) is a conventional bung for keeping liquid in the flask 10 until it is to be dispensed into one or both of the cups 14,15.
Referring now to Figure 5, which shows a sectional view of the body 11 with the first and second cups 14,15 screwed on their mountings 20, there is clearly shown a vacuum-surrounded liquid container 30 within the body 11 which comprises a metal inner skin 31 and a metal outer skin 32 between which the vacuum is to be maintained, the skins 31,32 being welded together only around an opening 33 in the container 30 to its interior 34. The opening 33 is closable by the closure 12. The metal outer skin 32 is fabricated as upper and lower sections 34 welded together in a lap joint 35 halfway along the length of the container, as can be seen in the enlarged detail drawing of Figure 6.
The vacuum flask 10 also comprises an integral storage container 40 for sweetener, such as sugar or a synthetic sweetener, and whitener, which can be added to liquids poured from the receptacle into one or both cups. The storage container 40 is shown in Figure 7 in its open arrangement, and comprises a cylindrical body 41 having recesses 42 in its otherwise flat planar surfaces 43 ,and upper 44 and lower 45 lids, which are rotatably mounted on axial spindles 46 and 47. Holes 48 through the lids 44,45 are closed when the lid concerned is turned for its hole to be in register with the adjacent planar surface 43. When the hole 48 is out of register with the planar surface, the contents of the recess 42 concerned can be shaken out of the storage container 40 into a cup. The Hds 44,45 can be lifted clear of the cylindrical body 41 to clean or refill the recesses 42, as shown in Figure 7. The upper lid 44 has a raised centre 49 to help in opening it.
The storage container 40 is stored integrally in the bottom of the lower cup 15 from the outside in a suitable recess 50 which is shown in Figure 5, or which is provided in the base of the liquid container 30, or which is provided in the bottom of the upper cup 14. If required there may be two storage containers 40, of which each is provided in the bottom of each of the lower and upper cups 14,15. The storage container 40 protrudes at 52 slightly from the recess 50 so that it can easily be removed from the base of the lower cup for use, and this protrusion 52 can be seen in Figures 1 and 3. Figure 2 shows the protrusion 52 when the recess 50 is in the base of the liquid container 30.
An alternative storage container 60, to be stored in the same way as the one just described in relation to Figure 7, is shown in Figures 8-12. A cylindrical holder 61 with a flat base 62 and a narrow rim 69 has two semi-circular open-topped sections 63, 64 separated by a diametrical double- walled divider 65. A circular top 66 fits over the sections 63,64 and has a single diametrical wall 67 receivable within the divider 65. Lifting the top 66 opens the sections 63 for storage or dispensing sweetener from one and whitener from the other section 63,64.
Figure 13 is a detailed view of the underside of the liquid container showing the storage container 60 tucked in its recess 50. Three lead-ins 70 spaced around the edge of the recess 50 allow the container to be pulled out of the recess by its rim 69.
It will be appreciated that the vacuum flask of this invention provides integral and stylish storage of the two cups and sweetener/whitener integrally in its design for ready and repeated carrying and use by the consumer. The or each storage container is easily removed from its recess to serve its function of dispensing sweetener and/or whitener as desired and chosen by the user, and being cleaned and replenished. Each recess is also readily able to be cleaned and kept hygienic.
