her preferred features of the invention will be apparent from the following description.
The invention will now be further described, merely by way of example, by reference to the accompanying drawings, in which: Figure I is a front elevation of a vacuum flask according to a preferred example of the invention, Figure 2 is similar to Figure 1, but with both cups removed, Figure 3 is a front elevation of the lower cup, Figure 4 is a plan view of the closure of the vacuum flask of Figure I, Figure 5 is a sectional view of the vacuum flask of Figure I, Figure 6 is an enlarged detail view of the part of Figure 5 in circle 6, Figure 7 is a perspective view in its open arrangement of one version of the storage container of the vacuum flask of Figure I, Figure 8 is a perspective view in its open arrangement of a second version of the storage container of the vacuum flask of Figure I, Figure 9 is a plan view of the storage container of Figure 87
! 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.
Referring 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 I I over the closure 12, and a second cup 15 mounted on the opposite end 16 of the body 11.
I'he body 11 (see Figure 2) is basically made of stainless steel for strength, robustness and style, but has a central section which is a moulding or wrap-around sleeve 17 of a resilient and soft plastic such as a soft-feel thermoplastic rubber for decoration and/or protection purposes. Just above and below the sleeve 17, the 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 IS (see Figure 3) each have an outer skin 21 of stainless steel and a liner 22 of plastic material providing rigidity for the cup and 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
!' tending 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 firming 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 lids 44,45 can be lifted clear of the cylindrical body 41 to clean or refill the recess, 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 ol the liquid container 30. I he 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 I 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 vacunrn 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.
