Abstract

A system for sealably closing a reservoir is disclosed. The system can have a container and a slider. The container can have an orifice and catches and lips surrounding the orifice. The slider can be translatably attached to the container over the orifice. The slider can slidably engage the catch and lips to force the orifice closed. While attached to the catch and lips, the slider can create a pressurized seal of the orifice.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to the field of closeable and sealable fluid reservoirs. More specifically, this invention relates to reservoirs that can be closed and tightly and securely sealed, yet unsealed and opened rapidly.

2. Description of the Related Art

Light weight, resealable bags are used increasingly in sporting activities, such as hiking, biking, and snow sport activities like skiing and snowboarding. Limited access to the interior of typical bags makes cleaning more difficult and increases the potential for unclean and unsanitary bags. Once liquids placed in the bags are consumed, the remaining deposits encourage the growth of bacteria and mold. If left uncleaned, such growths can leave stains on the bag, may retain odors, taint any other fluids subsequently introduced into the bag, and create health risks. Regular and thorough cleaning of the inside of the reservoir is critical.

Commonly used bags for sporting are typically accessible through a relatively small side port in the bag, often covered by a removable cap. The side port limits the access to the interior of the bag, thereby limiting the ability to clean the interior of the bag.

Also, removing or adding large quantities of liquid to the typical bags is often cumbersome and messy due to the limited and constrained access to reservoir via the side port. The side ports can also limit the flow rate into and/or out of the bag, slowing the process of removing excess fluid from the bag or loading fluid into the bag.

Zipper-type closures have been developed for bags in some uses. Zipper closures allow for larger and wider openings than typical side ports, thereby allowing easy cleaning of the interior of the bags. Zipper openings also ease the process of removing and adding fluid to the bag, in speed, convenience and cleanliness. However, common zipper closures are not suitable for most sporting activities. The bags often receive forceful blows during regular use, causing large increases in fluid pressure inside the bag. Elements used to close the opening often need to be reinforced to ensure closure during use. For example, the caps on side ports are often threaded. However, zippers are often only a small portion of the length of the entire opening, leaving much of the opening exposed to rupturing upon increased reservoir fluid pressure.

Roll-top closures satisfy the above demands: reinforced openings capable of withstanding high-pressure; ease of internal reservoir cleaning; and rapid, convenient, and clean liquid addition and removal. However, some users feel that roll-top closures are cumbersome and slow to open and close.

Therefore, a closeable reservoir system is desired that is capable of ease of internal reservoir cleaning. A closeable reservoir system is also desired that can provide rapid, convenient and clean liquid addition and removal. It is also desired to have a closeable reservoir system that can withstand significantly increased fluid pressures without leaking. A closeable reservoir system is also desired that is easy and fast to open and close.

BRIEF SUMMARY OF THE INVENTION

A reservoir closure system is disclosed. The system has a container, such as a bag, and a sealing member.

The container can have a reservoir and an orifice. The orifice can have closed and open configurations. The reservoir can be in fluid communication with the orifice. The orifice can have an orifice closed length when the orifice is in the closed configuration.

The sealing member can be configured to slidably attach to the container. The sealing member can have has a seal length. The seal length can be at least substantially equal to the orifice closed length. The sealing mechanism can be configured to seal the container. The sealing member can have a substantially straight configuration.

The container can have a first catch having a first catch bottom. The first catch bottom can have a first catch angle. The first catch angle can be less than about 90degrees.

The sealing member can have one or more sealing member arms. The sealing member arms can be configured to attachably engage the catches of the container. The sealing member arms can have angled faces that correspond to angled faces on the catches. Any or all of the angles of the angled faces of the arms can be substantially equal to the angles of the angled faces of the corresponding angled faces of the catches.

The container can have a first end and a first side, and wherein the orifice is at the first end. The container can have an opening on the first side of the container. The reservoir system can have a cap removably attached to the opening. The cap can have a socket configured to attach to a tube.

The sealing member can be tethered to the container. The sealing member can be configured to be interference fit to the container.

DETAILED DESCRIPTION

FIG. 1 illustrates that a reservoir system 2 can have a reservoir container, such as a bag 4, and a sealing member, such as an elongated slider 12. The bag 4 can have a reservoir 6, such as one or more hollows. Multiple reservoirs (not shown) in the bag 4 can be divided into one or more separate compartments by one or more septa, bladders and/or other dividers.

The bag 4 can have a bag reinforcement 8, such as a bag seal. The bag reinforcement 8 can strengthen one or more higher-probability mechanical failure areas on the bag 4. The bag seal 8 can have thicker dimensions than the surrounding material. The bag seal 8 can have layers of the material of the bag 4 or a different material attached to and/or integral with the bag 4. The bag seal 8 can be along all or part (as shown) of the circumference of the bag 4, for example, excluding the portion of the bag adjacent to the orifice 10.

The slider 12 and the bag can be configured to facilitate slidably translating the slider 12 on the bag. The bag can have a guide. The guide can direct the slider 12 during use.

The slider 12 can have a slider seal configured to seal the orifice 10. The slider seal can be, for example, the location on the slider 12 where the dimensions of slider arms provide sufficient force on the bag 4 to seal the bag 4 with the slider 12 on the bag 4. The slider seal can have a slider seal length 16. The slider seal length 16 can be from about 5 cm (2 in.) to about 91 cm (36 in.), more narrowly from about 5 cm (2 in.) to about 46 cm (18 in.), yet more narrowly from about 17 cm (6.5 in.) to about 18 cm (7.0 in.), for example, about 17 cm (6.5 in.).

FIG. 2 illustrates that the bag 4 can have a first lip 17 (partially hidden) and second lip 18, for example, adjacent to the orifice 10. The first lip 17 can be opposite the second lip 18. The lips 17, 18 can be reinforced. The lips 17, 18 can be thicker and/or otherwise more reinforced and/or stronger than the surrounding bag material. The first lip 17 can have one or more first engagement members, such as first catches 20. The second lip 18 can have one or more second engagement members, such as second catches 22.

The bag 4 can be made from a single sheet or from separate sheets, for example, integrated and/or attached at bag seams 24. The lips 17, 18 can have lip seams 26. The lip seams 26 can be part of the bag seams 24. The seams can be leak-proof and water-tight.

The orifice can have an orifice length 28, for example in a closed configuration. The orifice length 28 can be equal to or less than the slider seal length 16. The orifice length 28 can be from about 3.8 cm (1.5 in.) to about 90.1 cm (35.8 in.), more narrowly from about 3.8 cm (1.5 in.) to about 45.2 cm (17.8 in.), yet more narrowly from about 15 cm (6.0 in.) to about 17 cm (6.8 in.), for example, about 15 cm (6.0 in.).

The bag 4 can have an opening on either or both sides of the bag 4. A removable cap can cover the opening. The cap can be attached by an interference or screw interface, for example. The cap can be as disclosed by U.S. patent application Ser. No. 11/445,771. filed Jun. 2, 2006, which is now abandoned, and herein incorporated by reference in its entirety.

DU PONT DE NEMOURS AND COMPANY™, Wilmington, Del.), Nylon, or combinations thereof. For example, the slider can be made from POM and the bag can be made from TPU.

Method of Making

The bag 4 an be molded and/or any and/or all of the elements of the bag 4 can be welded (e.g., RF welded) together. The slider 12 can be molded and/or any and/or all of the elements of the slider 12 can be welded (e.g., RF welded) together.

Methods of Use

FIG. 7 illustrates that before sealably closing the orifice 10, the slider 12 can be unattached to the bag 4. The slider 12 can be aligned to the top of the bag 4. The slider channel 98 can be substantially longitudinally aligned with the first and second catches 20, 22.

FIG. 8 illustrates that the slider 12 can be translated relative to the bag 4, as shown by arrow. The slider 12 can be slidably attached to the bag 4. The slider 12 can be translated in the direction of the longitudinal center axis. The guides 14, 15, lips 17, 18, and catches 20, 22 can direct the slider arms 88, 90 longitudinally along the top of the bag 4. The tapered configuration of the slider arms 88, 90 can direct the slider arms 88, 90 longitudinally along the top of the bag 4. The slider arms 88, 90 can force the first lip 17 toward the second lip18 . The slider sides 82, 84 can force the first catch 20 toward the second catch 22.

The slider 12 can be unattached from the bag 4 by translating the slider 12 in the direction relative to the bag 4 opposite that shown by the arrow in FIG. 8.

FIG. 9 illustrates that the reservoir system 2 can be in a sealed configuration. The slider 12 can be slidably attached and friction fit to the top of the bag 4. The slider 12 can provide pressure squeezing the orifice 10 closed.

FIG. 10 a illustrates that when the slider 12 is attached to the top of the bag 4, the slider 12 can sealably close the orifice 10. The slider 12 can apply pressure on the bag 4 at any combination of the following areas: where the slider top 86 contacts the lips 17, 18 and/or the catch 20, 22; where the catches 20, 22 contact the slider sides 82, 84; where the slider arms 88, 90 contact the catches 20, 22, where the slider arms 88, 90 contact the lips 17, 18, and where the arms 88, 90 contact the guides 14, 15.

The reservoir system 2 can have side-catch gaps 182 between the slider sides 82, 84 can the corresponding catches 20, 22. The reservoir system 2 can have a top-catch gap between the slider top 86 and the catches 20, 22 and/or lips 17, 18. The reservoir system 2 can have arm-catch gaps 186 between the slider arms 88, 90 and the corresponding catches 20, 22. The reservoir system 2 can have arm-lip gaps 188 between the slider arms 88, 90 and the corresponding lips 17, 18. With the slider 12 deployed to sealably close the bag 4, the side-catch gaps 182, top-catch gap 184, arm-catch gaps 186, and arm-lip gaps 188 can be from about 0 mm (0 in.) to about 10 mm (0.4 in.), for example about 0 mm (0 in.).

The slider arms 88, 90 can produce an arm compression force 190, shown by arrows, against the first and second lips 17, 18. The slider sides 82, 84 can produce a side compression force 192, shown by arrows, against the first and second catches 20, 22. The arm 190 and/or side 192 compression forces can minimize and/or prevent fluid leakage from the reservoir 6 out of the orifice 10.

When pressure in the bag 4 increases (e.g., when the bag 4 contains fluid and the bag 4 is squeezed), the first and/or second catches 20, 22 can impair the movement of the slider first and/or second arms 88, 90, respectively, in. an upward direction (with respect to the page of FIG. 10a), for example retaining the slider 12 on the bag 4.

FIG. 10 b illustrates that the slider 12 of FIG. 6b is configured to sealably close the bag 4 of FIG. 3b. The upper catches 50, 52 can be configured to engage and slidably attach to the slider upper channel 126. The lower catches 54, 56 can be configured to engage and slidably attach to the slider lower channel 128. FIG. 10c illustrates that the slider 12 of FIG. 6c is configured to sealably close the bag 4 of FIG. 3c.

The slider gaps 108, slider upper gaps 138 and slider lower gaps 142 can be configured to engage and slidably attach to the lips 17, 18.

The bags 4 illustrated in FIGS. 3d through 3g can be used with sliders 12 illustrated in FIGS. 6d through 6g, respectively. During use, the catch grooves 74, 76 can interference fit with the arm ridges 174, 176. During use, the catch ridges 78, 80 can interference fit with the arm grooves 178, 180.

FIG. 11 illustrates that the slider top 86 can be resiliently or deformably bendable. The slider top 86 can be rotatably bent, as shown by arrow. The slider second arm 90 can be fixedly attached and/or engaged to the second catch bottom 36. The slider second side 84 can be positioned directly adjacent to the second catch 22. The slider first side 82 and slider first arm 88 can be unattached to and/or disengaged from the first catch 20.

FIG. 12 illustrates that the slider 12 can have one or more rotatable elements, for example hinges or joints. The joint 194 can be at the intersection of the slider top 86 and the slider first 82 and/or second 84 side. The joint 194 can enable the slider top 86 to rotate with respect to the slider first 82 and/or second 84 side. The joint 194 can be fixable (e.g., lockable), for example when the slider top 86 is at a right angle with respect to the slider first 82 and/or second 84 side. The joint 194 can be passive and/or biased to force the slider top 86 to a right angle with respect to the slider first 82 and/or second 84 side.

FIG. 13 illustrates that the slider 12 of FIGS. 11 and 12 can be released and/or forcibly rotated, as shown by arrow. The slider first arm 88 can snap onto the first catch 20, fixedly attaching to the first catch bottom 34 and/or producing the arm compression force 190. The slider first side 82 can be directly adjacent to the first catch and/or producing the side compression force 192.

FIG. 14 illustrates that the orifice 10 can be opened when the slider 12 is not engaged to seal the orifice 10. Compressive forces, as shown by arrows, can be applied to the ends of the lips 17, 18. Tensile forces, not shown (but perpendicular to the shown compressive forces), can be applied to the sides of the lips 17, 18. The first lip 17 can separate from the second lip 18. The lips 17, 18 can open in a puckered configuration. During use, solids and/or fluids (e.g., potable water, other beverages) can be transferred into and/or out of the bag 4 from the open orifice 10. The flexible bag 4 can be turned inside out through the orifice 10, for example, to aid access and cleaning the inside of the bag 4. The lips 17, 18 can be configured to be resiliently biased to close.

The slider 12 can be attached to the bag 4. For example, a leash can attach the slider 12 to the bag 4. The leash can be attached to the first and/or second hole. Also for example, the slider 12 and/or bag 4 can have a catch configured so the slider 12 can not be completely slidably removed from the bag 4.

It is apparent to one skilled in the art that various changes and modifications can be made to this disclosure, and equivalents employed, without departing from the spirit and scope of the invention. Elements of systems, devices and methods shown with any embodiment are exemplary for the specific embodiment and can be used in combination or otherwise on other embodiments within this disclosure.
