referring to the drawings and , in particular fig1 , there is shown a multifunctional closure and attachment assembly 5 . closure and attachment assembly 5 has a container 7 with a sealing cap 9 coupled thereto via a flexible hinge 11 . the closure and attachment assembly 5 is made from plastic , but any rigid or semi - rigid material is contemplated . the closure and attachment assembly 5 allows for engagement to a breastpump , 30 for instance ( fig4 ), to express milk from a nursing mother &# 39 ; s breast which flows into the container 7 . the breastpump is disengaged and the cap 9 seals the container 7 for storage . after storage and upon use , the cap 9 can be left in place , or can be removed from the container 7 by breaking the hinge 11 . detaching the cap after use ensures the same container is not used for the repeat storage of breastmilk , if that is desired . further , detaching the cap may eliminate it as an impediment during feeding . this further eliminates the need for re - sterilization . the closure and attachment assembly 5 can also engage to a bottle nipple 32 ( fig5 ), as through a collar 34 such that the breastmilk stored in the container 7 can be fed to an infant . container 7 has an upper opening 13 that has a shoulder or lip 15 , and has a circumferential threaded outer arrangement 17 , as shown in fig2 . it is noted that container 7 can be any suitable structure sufficient to receive and retain breastmilk . the opening 13 and threaded arrangement 17 is configured to connect to and cooperate with a breastpump ( fig4 ). the opening 13 and threaded arrangement 17 not only cooperates with the breastpump , but integrally connects the same to facilitate the effective and efficient transfer of breast milk from a nursing mother &# 39 ; s breast to the container 7 . the opening 13 and threaded arrangement 17 is also configured to connect to and cooperate with a feeding nipple and collar arrangement ( fig5 ). opening 13 and threaded arrangement 17 can be of any size or shape necessary to effectively connect with a breastpump and feeding nipple in a conventional screw - on fashion . in reference to fig3 , cap 9 has a sidewall 19 and annular ring 21 that creates a channel 23 . annular ring 21 cooperates with the lip or shoulder 15 of opening 13 of container 7 to engage and seal the opening 13 with the cap 9 in a snap - fit . sealing cap 9 can have a different configuration and be formed of any suitable material sufficient to securely connect the cap 9 with the container 7 to seal fluid therein . cap 9 has a tab 25 that projects outwardly from sidewall 19 to facilitate a user &# 39 ; s ability to connect and disconnect the cap 9 with the container 7 . cap 9 remains coupled to the container 7 via the flexible hinge 11 . the flexible hinge 11 integrally and flexibly connects the cap 9 to the container 7 . hinge 11 has two pivot points 27 , 29 . the cap 9 can easily be detached from the container 7 by breaking either pivot point 27 , 29 ( see fig3 ), if so desired . to seal contents in the container 7 , the cap 9 is placed over the opening 13 by pushing down toward the container 7 on tab 25 , although pushing down on any location on the cap 9 itself is contemplated to seal the container 7 . the opening 13 of the container 7 is sealed when channel 23 of cap 9 engages with shoulder 15 . the hinge is located and designed so that the cap can be swung far enough away from the opening 13 to permit the easy use of the screw - threaded attachment for the container that is also provided . while particular reference is made to a breastpump environment , there are many other applications to which the present invention may apply . while the apparatus and method herein disclosed form a preferred embodiment of this invention , this invention is not so limited , and changes can be made therein without departing from the scope of this invention which is defined in the appended claims . those of skill in this art will recognize potential features / designs which can be used in other embodiments , and even more variations , applications and modifications that will still fall within the spirit and scope of the invention , all as intended to come within the ambit and reach of the following claims .
an integral container closure securely seals the contents , such as breastmilk , within a container as well as provides for the rotary attachment of the container to other structures such as a breastpump .
