Abstract
Description
- This invention relates generally to a carrying case, and in particular, to a carrying case equipped with a latching device serving as part of a pressure relief valve and the latch closing opposite mating case sections while scaling the interior of the case.
- Carrying cases store and transport different types of goods. Some cases are designed to protect their content from hostile environments in addition to allowing for the transportation and storage of the goods. For example, thick shell polycarbonate cases can be used to store electronic equipment such as phones and BlackBerrys during camping trips. The protection from humidity and water often requires the use of seals on the case at junctions of the different surfaces that are opened to access the interior of the case. Some polymer-based seals serve to hermetically or hydraulically seal mating case sections.
- Once sealed from the exterior, cases may sometime encounter environmental conditions where barometric pressures vary. Sealed containers, such as carrying cases with an interior volume at partial vacuum, can be problematic to open. At a full vacuum, external pressures of up to 15 lbs per square inch must be overcome to open the case. For example, if the case is placed in the depressurized baggage compartment of an airplane for an extended period of time, air in the interior of the case, initially at atmospheric pressure, will slowly leak until the interior reaches equilibrium with the depressurized compartment. Once the plane lands, sudden external forces may compress (he seal between the mating case sections and prevent the equilibrium of the internal pressure with the atmosphere. Another example of depressurization happens when the internal air is somehow heated and cools once the case is closed.
- Some cases are equipped with tabs to increase the opening leverage, while other cases may be equipped with pressure relief valves to equilibrate pressures. U.S. Pat. No. 6,955,381 describes such a case equipped with a pressure relief valve placed on the external shell. The valve is manually operated. The problem with these types of valves is the need to create an additional opening in the case, which often serves as a leak path upon failure of the valve. If these valves are left open by the operator, the entire purpose of the sealed case is defeated. In addition, if these types of valves are designed with a membrane or other dynamic segment to seal liquids while allowing the passage of air, the valves lose much of their efficiency in permanent contact with a liquid or condensed humidity. These valves are also vulnerable to shock and can be damaged easily if the case is dropped.
- What is needed is a case equipped with a pressure relief valve placed at a location protected from shock and capable of sealing both gasses and liquids within the case where the valve cannot be mishandled or left in an inoperative position.
- This invention discloses a carrying case made of mating case sections with a principal seal and equipped with a latching device serving as part of a pressure relief valve for opening the interior of the carrying case with the atmosphere. The latch further includes a sealing means in contact with the external edge when the latch is opened to allow the passage of air through the opening when the latching device is opened and the sealing means is no longer in contact with the external edge of the opening.
