 This application is a continuation-in-part of applicant's copending U.S. application Ser. No. 09/659,322, filed Sep. 12, 2000, which in turn claims priority from earlier filed copending design patent application Ser. No. 29/122,027 filed Apr. 18, 2000 and from earlier filed copending U.S. non-provisional patent application Ser. No. 09/624,734 filed Jul. 25, 2000.
 The present invention relates generally to an improved drink mixer, and more particularly to a drink mixer which may be used by adults and children to make a wide variety of mixed drinks; including but not limited to milk shakes or smoothies, a drink including fruit and yogurt, and frothed milk.
 Drink mixers are well known in the art. Typical examples run from the hand-operated egg beater, electrical powered mixers with two egg beaters, or a dough hook, an electrically powered blender such as the type shown in British patent 1,378,240. Devices for making milk shakes or smoothies which have been designed for children include the Baskin-Robbins Shake and Smoothie Swirler, made by Wham-O, this device resembling the blender of the aforementioned British patent. Other variations include the HogWild Mr. Twister, the Easy Bake Smoothie Maker and the Easy Bake Blender. Other prior art mixers include a single shaft mixer of the type shown in U.S. Pat. No. 5,204,263, or a simple shaker of the type shown in U.S. Pat. No. 4,003,555.
 In addition to the mixers set forth above, there is another class of mixers which essentially contains a cylindrical container having a lid, there being a reciprocal shaft passing through the lid, the shaft carrying at its lowermost end an apertured disc. Examples of this form of construction are shown in U.S. Pat. Nos. 1,590,831, 2,291,708, 3,589,685, 4,737,036, 4,946,286, 5,327,816, 5,939,122, U.S. design Pat. Nos. 181,143 and 405,642, and British patent GB 237,668. In addition to these drink mixers, butter churns are also known of a similar construction, typical examples being shown in U.S. Pat. Nos. 85,187 and 993,130. In addition to the prior art mentioned above, other devices are known for the purpose of mixing milk with air to form a froth, and these milk frothing devices typically require heating means, usually in the form of steam. An exception is US
 While the foregoing devices are generally satisfactory for their intended design purposes, they are somewhat limited in their application. Many require electrical power. Others require steam for their operation. Others are too limited in their application. Many of the devices are not robust enough to chop a product such as a banana or melon, and to mix the chopped product with a liquid, such as yogurt. Other devices also lack the required strength for making milk shakes from milk and ice cream or similar products such as frozen yogurt, ice milk, sherbets, or frozen tofu/soy desserts. Other devices are not suitable for use with children because they are easily broken and require a degree of manual dexterity not present in children. Furthermore, these devices may be easily tipped over and their contents spilled.
 For example, U.S. Pat. No. 5,939,122 discloses a manually operated milk frothing apparatus which does not require steam, which is required by most prior art milk frothing devices. While this device is suitable for adult use, it has several disadvantages for use with children. Initially, the container is made of glass, which may not be a suitable material for use with children. In addition, the container top can be easily dislodged from the container, and even when in place it will not fully retain the contents of the container if the container should happen to be accidentally knocked on its side. The plunger of the above prior art device includes a number of parts which may be disassembled for cleaning, these parts including a bottom plate, a top plate, an annular spring, and a wire mesh screen which is cup shaped. When these parts are disassembled these parts may easily become lost or misplaced. In addition, the wire mesh screen may become bent or distorted in shape to such an extent that it may be difficult to reassemble. Furthermore, the wire mesh screen has fine apertures which easily become clogged, and which does not make the device suitable for a number of products.
 Other products have other disadvantages which are overcome by the present invention.
 It is an object of the present invention to provide a drink mixer capable of mixing a liquid such as, but not limited to, milk with a wide variety of other ingredients which may be air, another liquid, frozen confections such as ice cream, or even solids, such as Nesquik® flavored powders, or fruits such as bananas, strawberries, kiwis, blueberries, and watermelons.
 It is a further object of the present invention to provide a drink mixer which can be operated by children as well as by adults without potential adverse consequences.
 It is a further object of the present invention to provide a drink mixer which is of low cost, and which is easy to operate and manufacture.
 It is a further object of the present invention to provide a drink mixer which will have play value for children by permitting the children to view the action of the liquid as it is mixed with other ingredients.
 A still further object of the present invention is to provide a drink mixer which is easy to disassemble, clean, and reassemble.
 A further object of the present invention is to provide a drink mixer which may avoid spills.
 Yet another object of the present invention is to provide a drink mixer which is made of sturdy parts, which parts may not become broken if the device is dropped.
 Another object of the present invention is to provide a drink mixer which will allow a greater variety of ingredients to mix in milk, for example yogurt, protein powders, syrups, off the shelf flavored drinks such as Nesquik® Banana milk, or which will allow non-traditional milk liquids to be frothed, for example soy milk.
 Another object of the present invention is to provide a drink mixer which has temperature indicating indicia to indicate when ingredients such as milk and ice cream have been properly mixed.
 The foregoing objects of this invention, as well as others, are accomplished by providing a drink mixer has a tapered container having an open top, a bottom, and sidewalls extending upwardly from the bottom to the top, the top of the container being wider than the bottom of the container; a container top assembly which may be secured onto the top of the container to close the top of the container, the container top assembly including a top having a centrally located opening and a pour opening located to one side of the centrally located opening, and a cover lid for opening and closing the pour opening; a handle assembly which may be secured into the centrally located opening in the dome shaped top to close the centrally located opening, the handle assembly including a support element which passes through the centrally located opening and which may be interconnected thereto for reciprocal movement; and a mixing disk carried by the lower end of the support element, the mixing disk having a plurality of apertures through which liquid may pass when movement of the support element causes the mixing disk to be moved up and down, thereby mixing the liquid with other ingredients. In the illustrated embodiment the cover lid is part of a pour spout assembly including a pour spout which in received in the pour opening, the cover lid being a flip top pour spout cover lid secured to the pour spout by a hinge for movement between open and closed positions. This construction is shown in the following drawings and is described in greater detail below.
 In the following description upper and lower references are related to the normal operating position of the drink mixer. This position is shown in

 The drink mixer of this invention may also be used with off the shelf flavored drinks, i.e., Nesquik® Banana milk, Chocolate milk, Strawberry milk, or Hersheyls® products, etc. As previously mentioned, the drink mixer may be used to mix liquids with solids, such as Nesquik® flavored powders, which generally don't mix easily in other mixers.
 In operation, a child will place milk, and/or other ingredients, into the container, perhaps to a level line indicated at
 Another use of this invention is as follows: By adding cereal, especially Nesquik® cereal, to milk in the container, a novel drink is created. The cereal releases the chocolate flavor (which it is intended to do in milk) but the entire surface area of the cereal is submersed in the milk extracting the chocolate flavor more than what would occur in a bowl of milk. By continuing to froth the milk, with the cereal added, a very novel way of preparing and “drinking” the cereal is achieved.
 With reference now to
 While a specific form of drink mixer has been illustrated, it should be obvious that other forms and designs may be utilized. For example, the mixing disk may be mounted on the lower end of a rod which extends through the central aperture and has a spring disposed between the handle top and the top of the top
