DETAILED DESCRIPTION OF THE DRAWINGS

[0022] FIG. 1 shows a container 10 with a display device 20 in a first state to indicate a first or second type of material in the container 10 in accordance with a first embodiment of the present invention. Container is a broad term, which includes, any type of container for holding liquids, solids or gasses. For example container includes a gasoline container, a storage bin, a test tube, and any other type of container. In the embodiment of FIG. 1, the container 10 is a gasoline container or gasoline/oil mixture container. The first type of material is a gasoline/oil mixture. A designation 24 in alphanumeric characters of “Gas/oil” is shown as a designation, symbol, or indication, to specify that a mixture of gasoline and oil is in the container 10. The container 10 is also comprised of a receptacle portion 12 for storing liquid such as gas or a gas/oil mixture, a cover portion 14 having a cap 16 for taking off to insert gasoline into the container 10, and a spout 18.

[0023] The display device 20 is comprised of a sliding member 21. The sliding member 21 should be opaque so that it covers whatever area it is located over. The display device 20 is also comprised of frame or 22, which includes portions or borders 22a, 22b, 22c, and 22d. The sliding member 21 can slide within frame 22 from a first state or position shown in FIG. 1 to a second state or position shown in FIG. 2. The portion 22d contacts and prevents the sliding member 21 from sliding any further to the left from the first state shown in FIG. 1. The portion 22b contacts and prevents the sliding member 21 from sliding any further to the right from the second state of FIG. 2. The portion 22c keeps the sliding member 21 from falling downwards and the portion 22a keeps the sliding member 21 from moving upwards. In this manner the sliding member 21 is connected or attached to the container 10. Each of the portions or borders 22a-d may have a channel which allow the sliding member 21 to slide underneath a portion of the borders 22a-d but which do not allow the sliding member 21 to become separated from the container 10. Each of the portions or borders 22a-d may be fixed to a front side 26c of a backing 26 which may be attached to the container 10 such as by gluing or in a detachable adhesive manner, or in any other known manner.

[0024] The display device 20 may be sold or provided separately from the container 10. The display device 20 may have a backing 26 with a front side 26c (shown in FIG. 1) and a back side 26d (shown in FIG. 10). On the back side 26d of the backing 26 may be placed an adhesive for attaching or detaching the display device 20 from the pitcher 10. The portions 22a-d, the backing 26, and the sliding member 21 may be integrated together to form the display device 20.

[0025] In operation a person, who may be the person inserted and/or filled the container 10 with gasoline or an oil/gas mixture, which is contained in receptacle 12, may place the display device 20 in a first state to indicate that, for example, gasoline, is in the container 10. In this first state, shown in FIG. 1, the designation 24 “Gas/Oil” can be seen. This can be called a first visual indication of a first type of material within the container 10. The designation 24 “Gas/Oil” may be printed on a portion 26a of the backing 26. In the first state, the designation 25 “Gas” (shown in FIG. 2) is covered by the opaque sliding member 21, which has been slid completely to the left in FIG. 1.

[0026] An individual may change the display device 20 into a second state to indicate that a second type of material (which differs from the first type of material) is in the container 10. The individual would slide the sliding member 21 from the position in FIG. 1 to the position in FIG. 2. The edges of the sliding member 21 underneath the frame 22 are shown by dashed lines in FIGS. 1 and 2. In the second state of FIG. 2, the sliding member 21 has been slid as far to the right as it can be slid, until it contacts portion 22b of the frame 22. The sliding member 21 now covers the designation 24 for “Gas/Oil” and the designation 25 for “Gas” can be seen. This can be called a second visual indication of a second type of material within the container 10. The designation 25 for “Gas” is printed on a portion 26b of the backing 26. The backing 26 may be a material such as plastic or hard cardboard. Instead of the “Gas/Oil” and the “Gas” designations for designations 24 and 25, the designations 24 and 25 may be for example (a) “acid” and “base”, (b) “milk” and “half & half”, (c) “sifted flour” and “un-sifted flour”, or (d) “sugar” and “saccharine”. Although the designations 24 and 25 will typically relate to the contents of the container, in one or more embodiments the designations 24 and 25 may not relate to the contents of the container. For example, if the container is a coffee mug, the designations 24 and 25 may merely show messages desired to be displayed by the user. For example, the designations 24 and 25 may be (a) “good mood” and “bad mood”, (b) “don't speak to me” or “I'm lonely and want to talk”.

[0027] The display device 20 may take on other forms. Other liquids or solids could be placed in the container 10. For example container 10 may instead be a box, which contains dry goods.

[0028] FIG. 3 shows a container 100 in accordance with another embodiment of the present invention. The container 100 includes an indicator device 117 and a control panel 122. The container 100 may be similar to the container 10 of FIGS. 1 and 2. However, the indicator device 118 of FIG. 3 has replaced the display device 20 of FIGS. 1 and 2.

[0029] The indicator device 117 includes push button lights 118 and 120, which are under designation “Gas” 118a, and “Gas/Oil” 120a respectively. The push button lights 118 and 120 are both toggle switches and as such if they are turned off, they will light up when pushed, and if they are turned on, they will turn off when pushed in. If an individual has placed gasoline only in the container 100 then they may cause the push button light 118 to light and cause the push button light 120 to stay off. Thus light 118 is lit under designation 118a for “Gas”. If an individual has placed a gas/oil mixture in the container 100 they may cause the push button light 118 to turn off and cause the push button light 120 to stay on. Thus light 120 is lit under designation 120a for “Gas/Oil”. In this way, any person who wants to use the material inside the container 100 will know whether the material is gas or a gas/oil mixture.

[0030] FIG. 4 shows a container 200 in accordance with another embodiment of the present invention including an indicator device 218 which is only a light in this example and which may emit one of two colors, to indicate whether material which has been placed in the container 200 is of a first type or a second type. The container 200 may be identical to the container 100 except for the difference between indicator device 117 and the indicator device 218.

[0031] The indicator device 218 is a push button single light, which can be toggled to emit either a green color light or a red color light. An individual can use, for example, green to indicate that gas only is in the container 200 and red to indicate that a gas/oil mixture is in the container 200.
