Benefits of technology

[0004]An easily closable and openable container system includes a number of features which facilitate easy opening and closing while maintaining a high seal. In a first embodiment, the opening forces can be concentrated on one narrow side which includes a lip 41 on one side of a lid flange and with an angled portion on the opposite side of the flange to give ease of opening with less force involved. In a second embodiment where one side is not significantly shorter than a longest side, the lid flange is located at a corner to concentrate the leverage for opening.
[0005]A continuous flange surrounds a generally planar member and mates with a outwardly projecting rim. The flange includes a pair of surfaces, including an inwardly angled surface which acts to form a stable seal, and actually urges the lid downward as the natural sealing force from the flange is app

Problems solved by technology

Most sealed containers commercially available have compromised the sealing engagement in order to facilitate a snap shut closure.
Quick engagement structures don't typically produce as strong of a seal as a more extended seal with significant sealing forces.

Example

[0015]The description, construction and operation of the sealing system of the invention will be best illustrated by beginning with reference to FIG. 1, which illustrates a perspective view of a rectangular oblong container 21 including a lid 23 and a base container 25. The base container 25 may include a generally circumferentially outwardly projecting rim 27 which may serve as a reinforcement for the upper part of the base container 25 and as a visual indicator that the lid 23 is fitted in place, by visually exacerbating any displacement from a flat sealed condition. Also seen are a periodic series of vertical reinforcements 29 which project slightly outwardly from the generally vertical extent of the base container 25.

[0016]The lid 23 has a number of features. Lid 23 includes a flange portion 31 made of a more flexible material. Flange portion 31 is continuous adjacent the periphery of the lid 23. Into the flange portion 31, a harder plastic portion 33 is fitted and sealed. Seali...

Abstract

An easily closable and openable container system includes a number of features which facilitate easy opening and closing while maintaining a high seal. In a first embodiment, the opening forces can be concentrated on one narrow side which includes a lip on one side of a lid flange and with an angled portion on the opposite side of the flange to give ease of opening with less force involved. In a second embodiment where one side is not significantly shorter than a longest side, the lid flange is located at a corner to concentrate the leverage for opening. A continuous flange surrounds a generally planar member and mates with a outwardly projecting rim. The flange includes a pair of surfaces, including an inwardly angled surface which acts to form a stable seal, and actually urges the lid downward as the natural sealing force from the flange is applied.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a number of advantageous structures and devices for safe, convenient, easy to open and close containment sealing systems which are ideal for preserved sealing, particularly for foodstuffs.BACKGROUND OF THE INVENTION[0002]Sealed containers are typically used in conjunction with food and other materials to be protected from moisture and the environment, or used with liquids and are to be isolated from spillage. Most sealed containers commercially available have compromised the sealing engagement in order to facilitate a snap shut closure. Quick engagement structures don't typically produce as strong of a seal as a more extended seal with significant sealing forces. Conversely, a good seal typically involves a complex locking arrangement or an extended seal. However, most complex locking arrangements or extended high pressure seals are inconsistent with ease of use and low expense.[0003]The need for an efficient and easily op...
