FIELD OF INVENTION
The present invention relates to a liquid dispenser, and more particularly, the present invention relates to a cap assembly for a liquid dispenser.
BACKGROUND
Water jugs are one of the popular means for carrying drinking water. These are available in different capacities ranging from 1 to 5 Liters, wherein water jugs of capacity one and a half gallons are more popular because of the portability. The available water jugs are manufactured in different shapes including round to square. However, the mouths of most of the available water jugs are the same i.e., of an upstanding cylindrical configuration. The broad mouths allow both filling water in the jug and drinking from the jug easier. The openings in the jugs can be closed by lids or caps. Such lids or caps can be secured to the upstanding walls of the opening of the jugs through a coupling mechanism. The coupling mechanism can be screw or snapping the cap to the mouth. However, known caps or lids suffer from one or more drawbacks. The major drawback is that the caps are not durable and are frequently compromised or lost. Moreover, many cap designs also suffer from water leakage problems. While standard jugs are popular, the lids or tops are not always dependable or durable resulting in the aforementioned problems.
Thus, a need is appreciated for a cap assembly for a drinking vessel that is devoid of the aforementioned problems of the known caps or lids.
