A bellows design collapsible polymeric storage tube. The device incorporates separate flexible plastic disks as segregating spacers that are dropped inside the device creating separate spaces for a plurality of items. The spacers lock into the widest part of the bellows securing them in place. The disks are printable/markable for promotional/informative media and labeling. In a first instance of the bellows receptacle, the collapsible bellows tube consists of two threaded ends and two threaded lids. The lids pop open and have their own separate space(s) that also uses a disk to create a separate segregated compartment. When a lid is empty the top of the lid collapses in upon itself thus saving space when the lid is empty and packed away, likewise the body of the tube collapses and expands as it is filled or emptied of the contents inside in order to save space when it is packed away. In a second instance of the present invention, the bellows receptacle uses a pair of segregating discs with each positioned approximate the top and bottom of the bellows receptacle forming closure for said receptacle. Any number of additional discs can be used to create segregated compartments within said bellow receptacle.

The invention discloses an integrally-forming method of a CFRP lenticular collapsible tube. The integrally-forming method comprises five steps as follows: (1), laying a prepreg on an upper female mold and a lower female according to a designed laying scheme, wherein the upper female mold is the same as the lower female; (2), after the prepreg is laid, the upper female mold and the lower female covered with the prepreg are assembled oppositely and locked together; (3), pressurizing the prepreg at the arc-shaped middle section of the CFRP lenticular collapsible tube clung to the mold through an air bag; (4), performing heating and solidifying on the prepreg according to the solidification process of the prepreg for preparing the lenticular collapsible tube; (5), after the solidification completion, cooling the prepreg until the temperature of the prepreg is the room temperature, and then opening the mold.
