Abstract
A food container includes a base section having a plurality of side walls and bottom section defining a hollow interior space and a base sealing mechanism that is secured along the upper portion of the side walls for engaging a removable lid having a plurality of side walls and a lid sealing mechanism located along a bottom end thereof. The sealing mechanisms of the lid and base sections including an elongated seem having a vertical and horizontal portion, and a single, elongated gap having horizontal and vertical portions.
Description
- The present invention relates generally to takeout style food containers, and more particularly to an improved sealing mechanism for the same.
- The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
- Takeout style food containers having a base section and a lid are designed to allow users to transport hot or cold food in a secure manner. To this end, these containers, which are typically constructed from plastic, are designed to maintain a seal between the base section and the lid, in order to isolate the inserted food items from the outside environment. Ideally, the base and lid are secured together in a manner sufficient to prevent accidental opening, while still allowing a user easy access to the food inside.
- Recently, food containers have begun to introduce air pockets for providing better sealing qualities and user access. One such example includes U.S. Pat. No. 6,460,716, to Wong, which includes a series of four seals arranged so as to create a pair of small air pockets at separate locations along the area between the base and the lid. Likewise, U.S. Pat. No. 6,056,138, to Chen includes a similar design that incorporates three air pockets and three seals (i.e., a triple seal) between the base and lid.
- Although these designs function well to preserve the interior contents of the container, they suffer from one serious deficiency. By positioning multiple air pockets in series with multiple independent seals, each of the separate air pockets act to create miniature vacuum points when attempting to remove the lid from the base. To this end, the use of the multiple air pockets and separate seals work to make the process of opening the container more difficult. As a result, many times, users are unable to easily separate the lid from the base. When this occurs, users are often forced to use tools to either pry the lid off, or to simply cut the lid from the base, which then renders the container unsuitable for future use.
- Accordingly, there remains a need for a food container capable of securely storing food items in an air and watertight manner that does not suffer from the drawbacks of the devices described above.
- The present invention is directed to a food container. One embodiment of the present invention can include a base section having a plurality of side walls and bottom section defining a hollow interior space for receiving and storing food items. A base sealing mechanism is secured along the upper portion of the base section for engaging a removable lid having a plurality of side walls and a lid sealing mechanism located along a bottom end thereof. The sealing mechanisms of the lid and base sections working in conjunction to form an elongated seem having a vertical and horizontal portion, as well as a single, elongated gap having a horizontal and vertical portion.
- This summary is provided merely to introduce certain concepts and not to identify key or essential features of the claimed subject matter.

To this end, thelid sealing mechanism 35 can include a downward slopingdiagonal rim section 35 a having an offset of approximately 30 degrees across a horizontal (X) axis, a generally vertical (Y axis) and upward extendingsection 35 b, a generallyhorizontal section 35 c and a vertical and downward extendingsection 35 d. As described above, each section of the lid sealing mechanism joins the distal end of the preceding segment, wherein the overall sealing mechanism extends outward, away from the removable lid as shown in the illustrated figures. - Accordingly, when the device is in a closed orientation, an air and watertight seem/seal is formed by the compression of
horizontal sections downward sections - In one preferred embodiment, the length of the
horizontal section 25 c will be less than the length of thehorizontal section 35 c, and the length of the upward extendingsection 35 b will be less than the length of the upward extendingsection 25 b. When so arranged, the differences in length act to form an elongatedair gap area 41. As shown, the elongatedsingle air gap 41 includes ahorizontal section 41 a separatingseal sections vertical section 41 b separatingvertical sections - By providing a single,
elongated air pocket 41, having both a horizontal orientation and a vertical orientation, thecontainer 10 can advantageously allow thebase section 20 and thelid section 30 to flex in both a vertical and horizontal manner (see arrow A) with respect to one another without causing the lid and base to separate. Moreover, the use of a single elongated air gap allows the lid to be easily opened without creating vacuum points. When this feature is combined with the sturdy seal provided bysections - In order to lock the
base 20 andlid 30 together, a lockinglip 45 can be integrally formed onto the distal end of theupper sealing mechanism 35. As shown, lockinglip 45 can include aninward radiating protrusion 45 a upon which therounded end 25 e of thebase sealing member 25 can rest. In one preferred embodiment, theprotrusion 45 a has a length equal to the thickness of thedownward section 25 d. Additionally, it is also preferred that the end of the lockinglip 45 be positioned in the same horizontal plane as the lowermost portion of thediagonal rim section 35 a (see X axis). To this end, thelid 30 can be easily separated from thebase section 20 by applying a pressure (see arrow B) onto the lockinglip 45. -
FIGS. 5 a and 5 b illustrate the stackability of thebase sections 20 andlid sections 30, respectively. As shown, a plurality ofbase sections 20 can be vertically stacked in a space saving manner owing to the design of thesealing mechanism 25. To this end, therounded edge 25 e of each base section can rest upon the outer edge of thehorizontal section 25 c of an adjacent base section, thus allowing the side walls be positioned adjacent to each other. Likewise, a plurality oflids 30 can be vertically stacked in a space saving manner owing to the design of thesealing mechanism 35. To this end, thecurved protrusion 45 a of each lockinglip 45 can rest upon the outer edge of thehorizontal section 35 c of an adjacent lid, as shown. - As to a further description of the manner and use of the present invention, the same should be apparent from the above description.
