The present Application is directed towards containers, and more particularly, to folding containers.
Businesses and consumers are trying find solutions to reduce waste from food packaging and find sustainable solutions. Plastic is often the material of choice in food packaging because it's lightweight, durable, and easy to manufacture. Every year, however, the world produces 400 million tons of plastic. More than 40% of the plastic trash generated is single-use, and it can stay in our environment for hundreds of years. Moreover, consumers are also increasingly becoming aware that chemicals can leech into food when plastic comes into contact with food.
Other consumers may not like the aesthetics of the typical rigid plastic food container. Plastic food containers can scratch and stain, especially when food is heated and eaten out of them directly. Rigid plastic containers can take up a lot of room when ported around in a backpack or a shoulder bag. Plastic containers can break when dropped. Finally, not all plastic is dishwasher or microwave safe.
Silicone is a safer option for food containers because it does not leech chemicals into food. Silicone that can be heated in a microwave and washed in a dishwasher safely. Due to the flexible nature of silicon, however, it can be tricky to build food containers out of it.
Prior food containers incorporating silicone often repurpose plastic container designs, removing the bottom plastic bowl portion and replacing it with silicone bowls that can be folded up when not in use. To facilitate orderly folds in the silicone, prior designs used a stepped profile in silicone material having a relatively uniform thickness of 0.4-0.7 mm. The stepped profile silicone bowls created eating containers that rapidly become narrower towards the bottom of the container, which in many cases is not an ideal container format for consumers to eat out of.
Prior silicone container bowls do not feel sturdy, especially when the containers have large pleats.
Some prior foldable silicone containers collapse too easily or are awkward to refold, and this is also often attributable to pleated sides.
Finally, silicone is also a very expensive material to manufacture from. This may be one of the reasons that prior silicone container bowls incorporate so much plastic into their designs.
What is needed is a foldable silicone food container that incorporates less plastic, minimizes contact between plastic and food, feels solid, is compact when folded, flexible to use, has attachable utensils that to not take up space reserved for food, is less expensive, is microwavable, and is elegant in design.

Turning to
In embodiments, first compartment storage portion 302 may comprise platinum silicone to provide a container with improved food safety. In embodiments, any other silicone component of container 100 may also comprise platinum silicone. Platinum silicone may help facilitate food safety certification, and it may help provide container 100 with a superior finish.
First compartment 300 further comprises a first compartment band 304 positioned around the mouth end of the first compartment storage portion 302. First compartment band 304 is formed from a material that is stiffer than the material comprising first compartment storage portion 302, and functions to provide rigidity around the mouth of first compartment 300, thereby providing structure to container 100. In embodiments, first compartment band 304 may be formed from plastic, composite, or bamboo. In further embodiments, first compartment band 304 may be formed from any material capable of providing additional stiffness to the mouth of first compartment 300. The junction member 200 engages the first compartment band 304 to form a lid thereon and provides means to seal the first compartment. In an embodiment, a mechanical means secures the junction member 200 to the first compartment band 304. The mechanical means may comprise at least one of snaps, levers, clasps, frictional fits, and threaded engagements. In the embodiment illustrated, threads 307 are shown on the first compartment band 304. The junction member 200 comprises mating threads (not visible) in this embodiment. When threaded together, the junction member 200 and first compartment band 304 are sealed such that a liquid placed in the first compartment 300 is securely contained therein.
In embodiments, first compartment band 304 may be positioned on an exterior surface of first compartment storage portion 302 to prevent first compartment band 304 from coming into contact with the contents stored within the first compartment 300. In embodiments, first compartment band 304 may be further coupled to first compartment storage portion 302 using an adhesive, such as a food-grade adhesive. In further embodiments, first compartment band 304 may be further coupled to first compartment storage portion 302 using any other method known in the art.
First compartment storage portion 302 is configured to be folded so that the entirety of the portion that extends below the first compartment band 304 fits within a volume defined by the of the first compartment band 304. In an alternate embodiment, only a majority of the portion that extends below the first compartment band 304 fits within a volume defined by the of the first compartment band 304. The first compartment storage portion 302 may comprise a pleat proximate a lower edge 305 of the first compartment band 304. By pleat, what is meant is two adjacent sections of a folded material connected via one angled bend in the material.
In embodiments, first container storage portion 300 further comprises an average thickness of silicon, with one or more regions of silicone being thinner than the average silicone thickness of first container storage portion 300. This allows first container storage portion 302 to form one or more predetermined pleats when pressure is applied to bottom end 308 of first container portion 300. In embodiments, one or more sections of silicone may comprise ring-shaped regions of thinner silicone arranged parallel to the periphery of the first compartment band 304.
In embodiments, first compartment storage portion 302 may comprise walls that have an average thickness that is between 1-4 mm. In further embodiments, however, first compartment storage portion 302 may have an average thickness that is between 2-3 mm. In embodiments, the one or more sections of silicone 316 that are thinner may be a fraction of a millimeter thinner than the average thickness. In embodiments, the one or more sections of silicone 316 may be 0.2-0.5 mm thinner, for example.
Those of skill will understand that, by using one or more sections of silicone 316 comprising ring-shaped regions of thinner silicon, it is possible to avoid the stepped profiles of prior art silicone containers. Prior art silicone containers use silicone having stepped profiles to facilitate folding that reduce the width of the container steeply to facilitate orderly silicone folding. The rapid narrowing of prior containers makes for a less room for storage, and a less aesthetically pleasing container to eat out of. Moreover, to avoid having the silicone dangle very far below the hard plastic covers when folded, prior art containers use a larger number of folds. Those of skill will readily understand that using one or more sections of silicone 316 comprising ring-shaped regions of thinner silicone allows container 100 to have fewer predetermined pleats, so that that the sides of the body of first container storage portion 302 will make the impression to the user as being predominantly vertical and smooth when unfolded.
In embodiments, the one or more sections of silicone 316 that are thinner than the average silicone thickness of first container storage portion 300 may be positioned on an interior surface of first container storage portion 302, as may best be seen in

In embodiments, annular ring portion 322 may comprise a flat surface facing junction member 200 to provide a seal against junction member planar portion 202. In further embodiments, however, annular ring portion 322 may have a raised ridge to provide a seal against junction member planar portion 202.
In embodiments, first compartment storage portion 302 may further comprise a lower seat lip 330, wherein a distance between annular ring portion 322 and lower seat lip 330 may be configured to snuggly secure first compartment band portion 304 to first compartment storage portion 302 between annular ring portion 322 and lower seat lip 330. In embodiments, first compartment band 304 may further comprise a lower band lip 334 configured to seat against lower seat lip 330, thereby further preventing first compartment band 304 from moving up or down with respect to mouth lip 310. In embodiments, adhesive, for example a food grade adhesive, may be further used to couple first compartment band 304 securely to first compartment storage portion 302.
In embodiments, junction member planar portion 202 may further comprise a valve 215. The valve 215 may be opened, as shown in
