This application relates to a collapsible travel bottle. Specifically, this application relates to a collapsible travel bottle with a flexible main body that includes an upper portion, a middle portion, and a lower portion. The flexible main body transitions between an expanded state in which the upper and middle portions are external to the lower portion and a collapsed state in which the upper and middle portions are fully enveloped within the lower portion. The lower portion may be bowl shaped and may have reinforced sides that maintains the bowl shape of the lower portion.
It is a primary objective of the present disclosure to provide a collapsible travel bottle. Consumers who desire to have a water bottle available for use “on the go” typically have two options. The first option is a disposable plastic water bottle, which is typically discarded following consumption of the liquid and, as such, creates waste. The second option is a reusable water bottle which, while reducing the waste, necessitates that the consumer carry the water bottle following the consumption of the liquid. Consumers typically select a reusable water bottle based on their concern of the impact that disposable cup waste have, on the environment, of the greater perceived material integrity of a reusable water bottle as compared to a disposable plastic bottle, and of the costs related to continually purchasing water bottles for single use. Consumers such as urban residents, city commuters, and university students have been less likely to utilize a reusable water bottle because of the need to store and transport the reusable tumbler on their person or in a briefcase or small bag they may be carrying following consumption. What is needed is a collapsible water bottle that provides for its easy transportation on a person or in a briefcase or small bag.
In some embodiments, a collapsible travel bottle is provided, the collapsible travel bottle including a flexible main body comprising an inner space for receiving a liquid therein, the main body including an upper portion, a middle portion, and a lower portion. The collapsible travel bottle further including an opening in the upper portion in communication with the inner space to allow receiving and discharging of the liquid within the flexible main body, a rigid collar that couples to the upper portion proximate the opening, a rigid cap removably coupled to the rigid collar to restrict receiving and discharging of the liquid within the flexible main body through the opening, and the middle portion configured to enable both the top portion and the middle portion to collapse fully into the bottom portion.
In some embodiments, a method of manufacturing a collapsible travel bottle is provided, the method including the steps of providing a flexible main body comprising an inner space for receiving a liquid therein, the main body including an upper portion, a middle portion, and a lower portion, providing an opening in the upper portion in communication with the inner space to allow receiving and discharging of the liquid within the flexible main body, providing a rigid collar that couples to the upper portion proximate the opening, providing a rigid cap that couples to the rigid collar to restrict receiving and discharging of the liquid within the flexible main body through the opening, and providing that the middle portion is configured to enable both the top portion and the middle portion to collapse fully into the bottom portion.
Still, other aspects, features, and advantages of this disclosure may be readily apparent from the following detailed description, as illustrates by the example embodiments. This disclosure may also be capable of other and different embodiments, and its several details may be modified in various respects. Accordingly, the drawings and descriptions are to be regarded as illustrative and not as restrictive.

As mentioned above, this application relates to a collapsible travel bottle. Specifically, to a collapsible water bottle including a flexible main body comprising an inner space for receiving a liquid therein, the main body including an upper portion, a middle portion, and a lower portion. The collapsible water bottle may further include an opening in the upper portion in communication with the inner space to allow receiving and discharging of the liquid within the flexible main body. The collapsible travel bottle further including a rigid collar that couples to the upper portion proximate the opening, a rigid cap that removably couples to the rigid collar to restrict receiving and discharging of the liquid within the flexible main body through the opening. The rigid cap is held in place during use of the collapsible travel bottle by a lower retaining ridge and an upper retaining ridge of a seating wall that extends from the upper portion. The middle portion configured to enable both the top portion and the middle portion to collapse fully into the bottom portion.
The flexible main body 102 may include an upper portion 106, a middle portion 108, and a lower portion 110. The combination of the upper and middle portions 106, 108 may have a generally tapered conical shape while the bottom portion 110 may have a generally round bowl shape. The conical shape allows the upper and middle portions 106, 103 to collapse fully into the lower portion 110. The upper portion 106 may have a thickness that is sufficient to maintain its shape while retaining its flexibility.
The lower portion 110 may include a flat bottom portion 112 that allows the collapsible travel bottle 100 to sit upright on a flat surface.
The flexible main body 202 may be comprised of any material known to one of reasonable skill in the art that is both flexible and waterproof, including silicone rubber and synthetic elastomer.
The cap assembly 104 may be removably coupled to the upper portion 106 of the flexible main body 102, the rigid cap assembly 104 providing access to an inner space 114 (not shown) defined within the flexible main body 102.
In the embodiment shown in
The seating wall 302, the lower retaining ridge 304 and the upper retaining ridge 306 may each be comprised of any material known to one of reasonable skill in the art that is both flexible and waterproof, including silicone rubber and synthetic elastomer.
The cap assembly 104 may include a rigid collar 310, a rigid cap 312, and a retaining strap 314. The rigid collar 310 may be cylindrical with an inner circumference that is generally equal to an outer circumference of the seating wall 302. A lower circumferential edge 310A of the rigid collar 310 may have a depth generally equal to a depth of the lower retaining ridge 304. Similarly, an upper circumferential edge 310B of the rigid collar 310 may have a depth generally equal to a depth of the upper retaining ridge 306. When set in place on the flexible main body 102, the rigid collar 310 may press against the cylindrical seating wall 302 and may be secured in-between the lower retaining ridge 304 and the upper retaining ridge 306. The lower retaining ridge 304 and the upper retaining ridge 306 hold the rigid collar 310 in place against the seating wall 302 while the main body 102 transitions between the expanded state and the collapsed state. Moreover, the flexibility of the seating wall 302 allows for the removal of the rigid collar 310 over the upper retaining ridge 306 when necessary.
A pair of opposite facing tabs 316 may extend downward towards the lower portion 110 from the lower circumferential edge 310A of the rigid collar 310. The tabs 316 may be used to grab and pull the upper portion 106 to enable the transition of the flexible main body 102 between the expanded state to the collapsed state. The tabs 316 may also be used to hold the collapsible travel bottle 100 while using the collapsible travel bottle 100 in the expanded state.
In one embodiment, the tabs 316 may be approximately 0.6 inches wide.
The rigid cap 312 may be removably coupled to the rigid collar 310 using complementary threads 318 on an inner surface 312A of the rigid cap 312 and on the outer surface 310C of the rigid collar 310. Once the rigid cap 312 has been fully screwed onto the rigid collar 310, the upper retaining ridge 306 is compressed in-between the inner surface 312A of the rigid cap 312 and the upper circumferential edge 310B of the rigid collar 310. This compression of the upper retaining ridge 306 provides for a liquid proof seal that serves to retain liquids within the inner space 114 of the flexible main body 102.
The rigid cap 332 may be removably coupled to the rigid collar 310 using any other means known to one of ordinary skill in the art.
The rigid collar 310 and the rigid cap 312 may each be composed of any rigid and waterproof material known to one of reasonable skill in the art, including plastic and metal.
The retaining strap 314 is configured to secure the rigid cap 312 to the rigid collar 310 while the rigid cap 312 is not coupled to the rigid collar 310.
Each of the plurality of minor stages 402 may have a generally diamond shape with a thick inflexible center 404 and thin flexible longitudinal edges 406. Each of the plurality of minor stages 402 is connected to one other at their respective flexible longitudinal edges 406. The thick inflexible center 404 provides for greater support while in the expanded state, while the thin flexible longitudinal edges 406 provide for greater flexibility while transitioning between the expanded state and the collapsed state.
The flexible longitudinal edges 406 allows each of the plurality of minor stages 402 to bend at its respective flexible longitudinal edge 406. Accordingly, the flexible longitudinal edges 406 allow each of the plurality of minor stages 402 to fold over a neighboring one of the plurality of minor stages 402 as the flexible main body 102 transitions between the expanded state and the collapsed state.
The upper articulating wall 408 may couple a first end 412 of the middle portion 108 to the upper portion 106. The upper articulating wall 408 is flexible in a manner as to bias the upper portion 106 into a portion of the inner space 114 defined by the middle portion 106 when a downward force 420, towards the lower portion 110, is applied at the upper portion 106.
The lower articulating wall 410 may couple a second end 414 of the middle portion 108 to the lower portion 110, the second end 414 of the middle portion 108 being opposite the first end 412 of the middle portion 108. The lower articulating wall 410 is flexible in a manner as to bias the middle portion 108 into a portion of the inner space 114 defined by the lower portion 108 when the downward force 420 towards the lower portion 110 is applied at the upper portion 106.
The upper articulating wall 408 and the lower articulating wall 410 are each sufficiently thin compared to the rest the main body 102 as to ensure that they are the first to collapse when the downward force 420 towards the lower portion 110 is applied at the upper portion 106.
The lower portion 110 may be generally round bowl shaped with a reinforcing element 416 embedded circumferentially within the walls 418 of the lower portion 110. The reinforcing element 415 may be rigid or semi-rigid as to maintain the round bowl shape of the lower portion 110 while the downward force 420 towards the lower portion 110 is applied at the upper portion 105. The reinforcement element 416 may be comprised of a thicker gauge of the same material comprising the flexible main body 102. The thicker portions of the flexible main body 102 having less flexibility of the remainder of the flexible main body 102.
