Storage container with a collapsible bellows unit
A storage container having a collapsible unit and a twist cap is described. The collapsible unit is a type of bellows which includes a base and a sidewall attached to the base. The sidewall has a spiral fold that traverses along a portion of the length of that the collapsible unit. The length can be compressed by folding the collapsible unit along the spiral fold. As the length of the collapsible unit is reduced, access to any remaining products, such as acne pad products, stored at the bottom of the collapsible unit can be more conveniently obtained. The cap of the storage container includes a ring collar; a sleeve attached to the ring collar; and a guide attached to the sleeve. When the cap is turned or twisted the guide and the spiral fold are configured to slidably engage each other which results in shortening the length of the collapsible unit.
1. A storage container comprising:
a collapsible unit comprising:
a base; and
a sidewall attached to the base, the sidewall having a spiral fold; and
a cap comprising:
a ring collar;
a sleeve attached to the ring collar; and
a guide attached to the sleeve wherein the guide being slidably engaged with the spiral fold of the sidewall of the collapsible unit,
and further
comprising an outer shell rotatably attached to the cap, wherein the outer shell containing the collapsible unit,
and further,
wherein the outer shell having at least one channel, and the collapsible unit having a least one nub wherein the nub and the channel are configured to mate together to substantially restrict the collapsible unit from turning, relative to the outer shell, when the outer shell is turned relative to the cap.

a collapsible unit comprising:
a base; and
a sidewall attached to the base, the sidewall having a spiral fold; and
a cap comprising:
a ring collar;
a sleeve attached to the ring collar; and
a guide attached to the sleeve wherein the guide being slidably engaged with the spiral fold of the sidewall of the collapsible unit,
and further
comprising an outer shell rotatably attached to the cap, wherein the outer shell
containing the collapsible unit,
and further,

3. A storage container comprising:
a collapsible unit comprising:
a base; and
a sidewall attached to the base, the side wall having a spiral fold; and a cap comprising:
a ring collar;
a sleeve attached to the ring collar; and
a guide attached to the sleeve or in the guide being slidably engaged with the spiral fold of the sidewall of the collapsible unit; and
further comprising an outer shell rotatably attached to the cap, wherein the outer shell containing the collapsible unit, and
wherein the collapsible unit is configured to expand in length when the cap is turned, relative to the collapsible unit, so that the guide slides along the spiral fold of the sidewall and results in unfolding a portion of the collapsible unit between the guide and the ring collar, and wherein the outer shell having at least one nub, and the collapsible unit having at least one channel wherein the nub and channel are configured to mate together to substantially restrict the collapsible unit from turning relative to the outer shell where the outer shell is turned relative to the cap.
