[0011] The figures depict embodiments of the present subject matter for the purposes of illustration only. A person skilled in the art will easily recognize from the following description that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the disclosure described herein.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] It should be noted that the description and figures merely illustrate the principles of the present subject matter. It should be appreciated by those skilled in the art that conception and specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present subject matter. It should also be appreciated by those skilled in the art that by devising various arrangements that, although not explicitly described or shown herein, embody the principles of the present subject matter and are included within its spirit and scope. Furthermore, all examples recited herein are principally intended expressly to be for pedagogical purposes to aid the reader in understanding the principles of the present subject matter and the concepts contributed by the inventor(s) to furthering the art, and are to be construed as being without limitation to such specifically recited examples and conditions. The novel features which are believed to be characteristic of the present subject matter, both as to its organization and method of operation, together with further objects and advantages will be better understood from the following description when considered in connection with the accompanying figures.

[0013] These and other advantages of the present subject matter would be described in greater detail with reference to the following figures. It should be noted that the description merely illustrates the principles of the present subject matter. It will thus be appreciated that those skilled in the art will be able to devise various arrangements that, although not explicitly described herein, embody the principles of the present subject matter and are included within its scope.

[0014] FIG. 1 illustrates structure of double layered liquid bottle, in accordance with an embodiment of the present subject matter. As shown in the FIG. 1, the double layered liquid bottle 100 has a mouthpiece 104 from where liquid can be inserted and dispensed. Further, the mouth piece 104 has a first end 104a and a second end 104b. The double layered liquid bottle 100 has an inner compartment 101 which is diverging from circumference of the second end 104b of the mouthpiece 104, and an outer compartment 103 which is diverging from circumference of the second end 104b of the mouthpiece 104. Section view B-B shows the divergence of inner and outer compartment 101, 103. There is an air gap or air layer 102 in between the inner compartment 101 and the outer compartment 103. The air layer 102 act as an insulation layer to insulate the heat loss from the inner compartment of the bottle. The air layer 102 has pressurized air inside which restrict increase or decrease in temperature of liquid inside the inner compartment 101. Those skilled in the art will appreciate that the air layer could be easily replaced by a layer of some other inert or noble gas.

[0015] Further, the inner compartment 101 has substantially hemispherical shape at lower end. The outer compartment 103 has flat base 105 at lower end to place and support the double layered liquid bottle 100 in vertical position. Dimensions of the inner compartment 101 are smaller than the outer compartment 103. Further, size of the inner compartment 101 can be optimized based on the requirements of the container/bottle.

[0016] Generally, the water bottle is a container that is used to hold water, liquids or other beverages for consumption. The use of a water bottle allows an individual to transport, and drink, a beverage from one place to another. A water bottle is usually made of plastic, glass, or metal. Water bottles are available in different shapes, colors and sizes. Water bottles can be either disposable or reusable. Reusable water bottles can also be used for water, liquids such as juice, iced tea, alcoholic beverages, or soft drinks. Reusable water bottle can help save the environment, through reducing waste.

[0017] The plastic bottles used to hold potable water are made from polyethylene terephthalate (PET), because the material is both strong and light. The PET is a thermoplastic polymer that can be either opaque or transparent, depending on the exact material composition. As with most plastics, PET is produced from petroleum hydrocarbons, through a reaction between ethylene glycol and terephthalic acid. The PET is chosen because it is inexpensive, lightweight, reseal-able, shatter-resistant and recyclable.

[0018] In the present subject matter, the double layered liquid bottle is made from the recyclable PET. The present double layered liquid bottle is made from stretch blow molding process. The blow molding process is well known to a person skilled in the art.

[0019] The double layered liquid bottle 100 has been tested and proved that the present bottle does not allow the cold water to heat up quickly and it may take from and 4 more hours to reach the same temperature that it would take if it was just one bottle as is the case now a days in the drinking water bottles sold as seen at railway stations, etc. in India

[0020] It is seen that passengers travelling most specifically in summer need cold drinking water for their journey. In the bottles available so far the water of 0 C. gains heat and reaches a temperature of 18 C. in about one hour and a temperature 27 C. in 2 hours whereas in the present double layered liquid bottle the temperature reaches the same temperatures in 3 hours and 7 hours, respectively. This means the consumer can have the benefits of colder water for a period that is increased from 2 to 4 hours more. So the object of the/invention is to let the consumer have water retain its colder temperature for a much longer time. The present subject matter has been so designed that it may not impact the cost part of the sale price.

[0021] The present bottle is environment friendly.

[0022] Recycled polyethylene terephthalate (RPET) can be used to make many new products, including fiber for polyester carpet; fabric for T-shirts, long underwear, athletic shoes, luggage, upholstery and sweaters; fiberfill for sleeping bags and winter coats; industrial strapping, sheet and film; automotive parts, such as luggage racks, headliners, fuse boxes, bumpers, grilles and door panels; and new PET containers for both food and non-food products.

[0023] The present bottle is cost effective.

[0024] Drinking water bottles are an item of mass consumption and needs to be priced as low as possible to make it within the reach of even the poor people. This is only possible when the cost of production is low. Accordingly such bottles are produced with batch sizes running in lakhs and on automatic plants that make these continuously.

[0025] The present bottles can be manufactured using blow molding process.

[0026] Although embodiments for the present subject matter have been described in language specific to structural features, it is to be understood that the present subject matter is not necessarily limited to the specific features described. Rather, the specific features and methods are disclosed as embodiments for the present subject matter. Numerous modifications and adaptations of the system/component of the present invention will be apparent to those skilled in the art, and thus it is intended by the appended claims to cover all such modifications and adaptations which fall within the scope of the present subject matter.
