FIELD OF THE INVENTIONThe present invention relates to storage systems for perishable goods and, more particularly, to an apparatus configured to seal a storage bag.
BACKGROUND OF THE INVENTIONThere are a variety of problems associated with food being exposed to air. Non-dry goods are prone to spoiling if exposed to air. Food being frozen can also be subject to the condition known as freezer burn, which occurs when ice crystals form on food, drawing out the moisture within and leaving the food dried out. Both problems can be remedied by separating food from outside air in a storage bag. However, even the air within a storage bag is sufficient to cause food spoilage or freezer burn.
Modern consumers freeze large quantities of food on a regular basis for a variety of reasons. It is often more affordable to buy food in bulk to store for later, with freezing being the most efficient method of doing so. It is also often practical to prepare meals in advance to save time later, making it necessary that food remain fresh for extended periods of time. Consumers who prefer to buy fruits and vegetables fresh also need a means to preserve them for extended periods of time as the air contained in grocery store bags allows them to spoil quickly. Therefore, there is a need for a system allowing a consumer to create a vacuum seal within a storage bag.
A variety of systems have been implemented to meet this need. Examples of these systems can be found in U.S. Pat. No. 7,540,127 to Sung et al. and U.S. Pat. No. 7,004,632 to Hamilton. However, the prior art systems suffer from various drawbacks. Some systems require the use of specialized storage bags having integrated valves, and the vacuum equipment associated with these specialized storage bags can be bulky and difficult to store. Other systems heat seal the bags and thereby render them useless for additional use. Thus, these systems can be costly for a consumer needing to repurchase bags every time food needs to be stored.
Consequently, it would be desirable to create a device that is capable of sealing any kind of storage bag that addresses these and other drawbacks.
SUMMARY OF THE INVENTIONIn one embodiment of the invention, a clip apparatus for sealing storage bags includes a first body member, a second body member, a valve, a tongue, and a seal member. The first body member includes a first operating end. The second body member has a second operating end and is pivotally coupled with the first body member. The first and second body members move between an open position and a closed position. In the open position, the first and second operating ends are disengaged. In the closed position, the first and second operating ends are engaged and sealed together to define an internal space. The valve is configured to enable selective fluid communication between the internal space and the exterior environment around the clip apparatus. The tongue is disposed at least partially between the first and second body members. The tongue engages an interior of a storage bag and includes a flow passage extending between the internal space and the interior of the storage bag when the first and second body members are in the closed position. The seal member is located between the first and second body members and seals the internal space at least partially around the tongue.
The tongue may be hingedly coupled to one of the first and second body members. Alternatively, the tongue may be slidably mounted within the first and second body members. In this regard, the tongue may be slid into and out of an opening in a storage bag to evacuate air from the storage bag. The tongue may also include a sharp leading edge configured to cut an opening into a storage bag. A system for sealing storage bags may include the clip apparatus and a vacuum pump.
In another embodiment, a clip apparatus for sealing storage bags includes a body member having a sealed internal space and a valve communicating with the sealed internal space. A tongue extends from the body member and includes a flow passage communicating with the sealed internal space. The clip apparatus also includes first and second arms pivotally coupled to the body member and including respective first and second sealing gaskets configured to sealingly engage the tongue. When a storage bag is placed over the tongue, the first and second sealing gaskets seal the bag at the first and second arms. The first and second sealing gaskets may be biased together by a biasing member such as magnets.
In another embodiment, a method of evacuating a storage bag with a clip apparatus includes rotating first and second body members to an open position spaced from a tongue, and inserting the tongue through an opening in the storage bag. The first and second body members are then rotated to a closed position sealing the storage bag against the tongue. Finally, air may be forced from the storage bag through the tongue and a valve in the clip apparatus to thereby evacuate the bag.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with a general description of the invention given above, and the detailed description given below, serve to explain the invention.
