Abstract
Description
technical field
[0001] The present invention belongs to the field of containers. Specifically, the present invention is an expandable container. Background technique
[0002] Containers such as peanut butter containers typically have a rigid form. That is, the container cannot expand or contract to accommodate the variable volume of substance inside the container. To use a peanut butter container as an example, it becomes increasingly difficult to obtain peanut butter from the bottom of the container as the contents of the container are consumed. Alternatively, there is a need to transfer large quantities of substances from, for example, metal containers into containers that will not corrode when exposed to air. The transferring container will be larger than the receiving container, so it is necessary to find a container with enough space to hold all the contents of the can. In both cases it is beneficial to have expandable or collapsible containers. For expandable cont...

[0016] Patterns for the invention
[0017] Referring now to the drawings, the present invention 10 is an expandable container shown generally at 10 comprising a body 12 having a bottom portion 14, a top portion 16 and a bellows disposed between the bottom portion 14 and the top portion 16 Part 18. figure 1 and image 3 Bellows portion 18 is shown in the fully expanded configuration as it would appear when filled with a consumable substance such as peanut butter. The consumable substance will have a fill level 20 within the expandable container immediately adjacent the top portion 16 . When the consumable substance is partially consumed, the container will render figure 1 The fully expanded structure shown and figure 2 Partially collapsed structures (not shown) between the fully collapsed structures shown. exist figure 2 and Figure 4 A fully collapsed configuration in which the bellows portion 18 is fully compressed is shown in . exist figure 2 a...
