The prior art teaches various cooling garments that include sealed containers of a cooling fluid (e.g., ice water). The cooling fluid is circulated through the garment to cool a person in a hot environment, and/or a person engaged in strenuous physical exertion. However, the cooling fluid is prone to leak if the sealed container experiences physical trauma during use of the cooling garment. The prior art does not teach a watertight container that includes a very strong seal to prevent leakage in spite of extreme shaking and physical impacts upon the cooling garment. The present invention fulfills these needs and provides further related advantages as described in the following summary.
SUMMARY OF THE INVENTIONThe present invention teaches certain benefits in construction and use which give rise to the objectives described below.
The present invention provides a watertight container for use in a cooling garment. The watertight container includes a container body, and first and second elongate locking elements. The container body is flexible and waterproof, and includes a side wall that defines an interior and extends to a perimeter that defines an opening to the interior of the watertight container. The perimeter of the container body has a first portion and a second portion, the first portion has a first plurality of apertures, and the second portion has a second plurality of apertures that each correspond with one of the first plurality of apertures. The first elongate locking element is rigid and adapted to abut the first portion of the perimeter of the container body. The second elongate locking element is rigid and adapted to abut the second portion of the perimeter of the container body. A plurality of fasteners removably fasten the first and second elongate locking elements together. The plurality of fasteners are adapted to be positioned through one of the first plurality of apertures of the container body and the corresponding one of the second plurality of apertures, such that the first and second elongate locking elements together close the opening of the container body.
In one embodiment, the container body includes a first side opening through the side wall, and a second side opening through the side wall. A first conduit and a second conduit is operably attached to the container body so that the first and second conduits are in fluid communication with the interior of the container body through the respective first and second side openings.
In one embodiment, the cooling garment includes a garment body adapted to be worn by a user, and a length of tubing having an inlet end, and outlet end, and a medial portion. The medial portion is attached to the garment body, and a pump is adapted to pump a cooling fluid from the watertight container, through the length of tubing, and back to the watertight container via the first and second conduits.
A primary objective of the present invention is to provide a watertight container having advantages not taught by the prior art.
Another objective is to provide a watertight container that is adapted to be used with a cooling garment.
A further objective is to provide a watertight container that seals closed in a secure manner so that the watertight container does not during the use of the cooling garment, despite extreme shaking and physical impacts upon the cooling garment and/or the watertight container.
Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

In one embodiment, the cooling unit 36 may include a reservoir 38 for storing the cooling fluid 12, and a pump 40 that is adapted to pump 40 the cooling fluid 12 through the tubing 26. The reservoir 38 may be, for example, a plastic bag or similar container that may be sealed to contain the cooling fluid 12. One embodiment of the reservoir 38 is illustrated in
The pump 40 may be electronically or manually powered, and may be any form of pump known in the art, as illustrated in
In one embodiment, the cooling fluid 12 is ice water that is conveyed by the pump 40 through the length of tubing 26, effectively cooling the user 14. As the ice in the reservoir 38 melts, it merely adds to the supply of water in the cooling garment 10, and if needed, the user 14 may drink the water for hydration, especially in the event of an emergency.
The cooling garment 10 cools the user 14 when the ice water 12 stored in the reservoir 38 is pumped via the pump 40 through pump tubing 44 to the connector/valve assembly 50 where it is then conveyed into and through the length of tubing 26. The ice water 12 then exits the tubing 26 through reservoir tubing 46 and returns to the reservoir 38 of the cooling unit 36. The cooling fluid 12 flows in a continuous loop through the cooling unit 36, the connector/valve assemblies 50, and the length of tubing 26 until the user 14 deactivates the pump 40 and ceases the flow of the ice water 12.
As shown in
The first valve housing 52 may be any form of housing defining a conduit 54 or some form of hollow chamber through which the cooling fluid 12 may pass. The first valve housing 52 includes a unit connector 56 for operably connecting the first valve housing 52 with the cooling unit 36, and a first connector 78 for connecting the first valve housing 52 with the second valve housing 70, as described in greater detail below. In one embodiment, the unit connector 56 is a fitting such as a tubing barb that removably engages the pump tubing 44 that is operably connectable with the pump 40. While one embodiment of the unit connector 56 is illustrated herein, alternative or equivalent embodiments known in the art may also be utilized, and should be considered within the scope of the present invention.
The first valve housing 52 also includes a first valve element 58 for regulating the flow of the fluid 12 through the first valve housing 52. In the embodiment of
The first valve housing 52 may also include a first actuator 68 for operably controlling the first valve element 58. In one embodiment, the first actuator 68 may be a lever or similar element (e.g., knob, pin, screw, etc.) for operably controlling the position of the barrel 60 in the present embodiment of the first valve element 58 (or operably controlling any other form of valve). In one embodiment, the first actuator 68 may be a generally U-shaped lever with each end attached to one of the ends 66 of the barrel 60 of the first valve element 58.
The second valve housing 70 may be substantially similar to the first valve housing 52, and may include a tubing connector 72, a second connector 82, a second valve element 74, and a second actuator 76. The tubing connector 72 may be a fitting such as a tubing barb, or equivalent connector, as described above. The second connector 82 is adapted to removably engage the first connector 78.
As shown in
As shown in
When the cooling garment 10 is not being worn, or when the user 14 wishes to remove the cooling garment 10, it is first necessary to cease the flow of fluid as well as contain the fluid. If the cooling garment 10 is being used, the user 14 first turns off the pump 40. As illustrated in
In the embodiment of
As illustrated in
When the user 14 wishes to remove the cooling garment 10 and cease the flow of fluid 12 as well as contain the fluid 12, the user 14 again turns off the pump 40 and turns the first and second actuator 68 and 76 of each of the connector/valve assemblies 50 to the closed configuration of
If the cooling garment 10 is worn for a long time, and the supply of ice is exhausted, additional ice may be added to the reservoir 38. Furthermore, in the event of an emergency (e.g., a motorcycle breaking down in the middle of the desert), the user 14 may close the first and second valve elements 58 and 74 of each of the connector/valve assemblies 50 to conserve the water, and then drink the water from the tubing 26 and the reservoir 38, until help arrives.
The mere reversal of any of these elements, or exchanging them for equivalent elements, is hereby expressly defined to be within the scope of the claim terminology, and is therefore expressly within the scope of the following claims.
The container body 102 has a side wall 104 that defines an interior 106 and extends to a perimeter 108 that defines an opening 110 to the interior 106 of the watertight container 10. The perimeter 108 of the container body 102 has a first portion 112 and a second portion 114, the first portion 112 having a first plurality of apertures 116, and the second portion 114 having a second plurality of apertures 118 that each correspond with one of the first plurality of apertures 116. The first and second portions 112 and 114 may be pulled away from each other, for the purpose of filling the container body 102 with ice and/or water. The first and second portions 112 and 114 may then be placed adjacent to each other and locked together, to removably close the container body 102. It is critical that the first and second portions 112 and 114 be locked together with substantial strength, so that the opening 110 is not forced open during use of the cooling vest (e.g., following sudden movements, impacts upon the container body 102, etc.).
To securely close the opening 110 of the container body 102, the watertight container 100 further includes a first elongate locking element 120 and a second elongate locking element 122 that together sandwich the perimeter 108 of the container body 102, to close the opening 110. The first elongate locking element 120 is rigid and adapted to abut the first portion 112 of the perimeter 108 of the container body 102, and the second elongate locking element 122 is rigid and adapted to abut the second portion 114 of the perimeter 108 of the container body 102.
A plurality of fasteners 124 are further included for removably fastening the first and second elongate locking elements 120 and 122 together. The plurality of fasteners 124 are adapted to be positioned through one of the first plurality of apertures 116 of the container body 102 and the corresponding one of the second plurality of apertures 118, such that the first and second elongate locking elements 120 and 122 together close the opening 110 of the container body 102.
In one embodiment, the plurality of fasteners 124 comprise a plurality of locking apertures 126, a plurality of externally threaded posts 128, and a plurality of internally threaded locking nuts 130. The plurality of locking apertures 126 are positioned through the second elongate locking element 122.

Finally, the plurality of internally threaded locking nuts 130 are each adapted to threadedly engage one of the plurality of externally threaded posts 128 such that tightening the locking nuts 130 with respect to the externally threaded posts 128 clamps the first and second elongate locking elements 120 and 122 together, thereby compressing and sealing the opening 110 of the container body 102.
While the externally threaded posts 128 may be integrally formed with the first elongate locking element 120, they may also be separate screws that are positioned through the first elongate locking element 120. Furthermore, while the locking nuts 130 may be separate elements as illustrated, they may be integrally formed as part of the second elongate locking element 122. These and other equivalent constructions are considered within the scope of the present invention. Obviously, reversals of the claimed construction are expressly considered within the scope of the present invention, and the above-described terms are hereby defined to include constructions that are the reverse of those described.
In one embodiment, the watertight container 100 further comprises a ridge 132 extending longitudinally along the first elongate locking element 120, and a mating groove 134 extending longitudinally along the second elongate locking element 122.
