TECHNICAL FIELD
The present disclosure relates to the field of containers and closures. Particularly, the present disclosure relates to a drip free bottle and a cap assembly that prevents dripping of residual liquid while pouring from the top of the bottle.
BACKGROUND
The information in this section merely provides background information related to the present disclosure and may not constitute prior art(s).
Since a long time, the demand of bottles is increasing in daily life. Basically, the consumers are using such bottles to store the liquids such as cooking oil, medicine, shampoo, milk, and ink etc. and to pour liquid in desired quantity whenever it requires.
Generally, the bottles have a mouth and a neck. The mouth is located at the top of the bottles. The mouth of bottle is opened to receive and/or pour the liquid in amount desired by a user. The neck extends from the mouth towards bottom of the bottles. The neck is mainly configured to receive a cap. The cap is provided to cover the mouth of the bottle. The cap is constructed corresponds to the shape of the mouth and the neck of the bottle such that to prevent leakage when the cap is attached to the bottle. Further, the cap may be provided with a temper proof ring. The temper proof ring is placed to indicate that the bottle is not used till now. The temper proof ring tears out with the first rotation of the cap and after that, the user may pour the liquid. However, it is experienced that a small amount of liquid as residual liquid, drips down along with an outer surface of the bottle, after pouring, as shown in figure 1.
It is also experienced that the residual liquid usually clings to the outer surface of the bottle which attracts insects.

It is also experienced that a gap between the bottle and the cap gets increased as using the bottle from a long time by which the insects may enter in the bottle easily.
It is also experienced that a sharp edge of the tamper evident ring develops on breakage thereof, as shown in figure 2. This may harm to the user.
In view of the above limitations of the existing bottles and caps, there is immense need in the art to provide a drip-free bottle and cap assembly that overcomes one or more existing limitations of existing bottles and caps. Specifically, a drip-free bottle and cap assembly that prevents dripping of the residual liquid after pouring.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “having” should be interpreted as “having at least,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the

phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
