[0013] When disclosed herein, the composite bottle will be better understood by considering the following detailed description in conjunction with the drawings. The detailed description and drawings merely provide examples of various embodiments of the composite bottle. Numerous modifications are intended for various uses and design considerations, but for the sake of brevity and clarity, not all intended modifications may be individually described in the following detailed description. Those skilled in the art will understand how the disclosed embodiments vary, modify, and change without substantially departing from the scope of the embodiments described herein.

[0014] Conventional disposable water bottles may include a thin, one-piece body with a single cap positioned at the bottle's opening or mouth. Conventional reusable water bottles may include a rigid body with a lid and a corresponding cap.

[0015] However, conventional systems do not offer the ability to carry multiple bottles in a composite or nested configuration. Conventional systems require additional space when additional bottles need to be carried and stored. This occupies a relatively large space, making it difficult to provide a structure that can carry multiple bottles to support multiple users or carry multiple fluids.

[0016] The composite bottle configurations described herein may address some or all of the above-mentioned problems. The composite bottle includes an inner part adapted to be inserted into an outer part, with the inner part fixed together with the outer part, potentially reducing the overall package size of the composite bottle. The top is joined to the ends of the joined inner and outer parts to facilitate carrying and storage. The composite bottle may function as a single bottle in a composite configuration and may separate to form two individual bottles.

[0017] Figure 1 is a schematic diagram of a composite bottle according to one embodiment. This embodiment of the composite bottle provides a compact arrangement of multiple bottles that require only the space of a single bottle for carrying and holding.

[0018] In some embodiments, the composite bottle 20 is a composite container configured to hold liquid. For example, the composite bottle 20 can carry drinking water. In some embodiments, the composite bottle 20 may include an inner part 25 that is nested inside an outer part 120.

[0019] The inner part 25 can define an internal space 30. The inner part 25 can include an inner wall 35, an inner upper end 40, and a lower end 45.

In addition, the references to “disclosure” and / or “this disclosure” refer to the entire text of this document and all accompanying drawings, which are extended to the entire text of each subsection of this document, including the title of the invention, background, brief description of the drawings, detailed description, claims, and abstract, as well as any other documents and / or references incorporated herein by reference.

[0063] When used herein in relation to lists, "and" forms a group that includes all the elements enumerated. For example, an example described as including A, B, C, and D is an example that includes A, B, C, and D. When used herein in relation to lists, "or" forms a list of elements that may include any of them. For example, an example described as including A, B, C, or D is an example that includes any of elements A, B, C, and D. Unless otherwise noted, an example that includes a list of alternatively included elements does not exclude other examples that include various combinations of some or all of the alternatively included elements. An example described using a list of alternatively included elements includes at least one of the enumerated elements. However, an example described using a list of alternatively included elements does not exclude another example that includes all the elements enumerated. An example described using a list of alternatively included elements does not exclude another example that includes some combinations of the enumerated elements. When used herein in relation to lists, "and / or" forms a list of elements that are included individually or in any combination. For example, an embodiment described as including A, B, C, and / or D may include only A, A and B, A, B, and C, A, B, C, and D, etc. The boundaries of the "and / or" list are defined by the complete list of combinations and the sorting of the list. When multiple specific elements are shown in the figures, and it is clear that the elements are repeated across the figures, only one label may be provided for the element, even though multiple examples of the element are shown. Therefore, other examples in the drawings of an element having the same or similar structure and / or function may not be repeatedly labeled. Those skilled in the art will recognize repeated and / or overlapping elements within the same drawings based on the disclosure herein. Nevertheless, repeated labeling may be included if it is useful in clarifying the structure of the illustrated embodiments. Applicant(s) have the right to file claims relating to novel and non-obvious combinations and subcombinations of disclosed embodiments. Embodiments embodied in other combinations and subcombinations of features, functions, elements, and / or properties may be claimed through amendments to those claims or through the presentation of new claims in this application or related applications. Such amended or new claims, whether relating to the same embodiment or a different embodiment, and whether different from, broader than, narrower than, or equal to the original claims, should be considered to be within the subject matter of the embodiments described herein.
