the objects , features and advantages of the invention will be apparent from the following detailed description of a preferred embodiment of the invention , which illustrated in the accompanying drawings in which like reference numbers indicate like parts of the invention . turning to fig1 a , an aseptic drop - in package ( 1 ), for perishable beverages and other liquids is shown . the drop - in ( 1 ) package preferably has a generally cylindrical shape , but it could take a substantially rectangular shape as well without adverse effect on functionality . this container portion ( 2 ) of the package is preferably constructed of molded or heat formed semi - rigid plastic using similar materials and methods used to manufacture crushable , disposable plastic cups . an annular flange ( 5 ) is formed around the top circumference of the container portion ( 2 ) to add reinforcement to the round shape of the container portion , and to provide a mechanical detente when the drop - in package is installed in a bottle or holder . the annular flange is shown wider than necessary in fig1 a and 1 b for illustrative purposes , and must only be of suitable width to hold the filled drop - in package in . place as described infra . the lid portion ( 7 ) of the drop - in package is preferably a two - ply design . the first ply is a thin hermetically sealed film which is stretched taut across the top of the container portion ( 2 ), and glued or heat sealed to the annular flange ( 5 ) so as to form a hermetically sealed reservoir ( 6 ) within the drop - in package . the first ply film is preferably constructed of a material which has high tensile strength , but is easily punctured through the thickness of the film . such materials include mylar film and aluminum foil . the second ply of the lid portion ( 7 ) is a thicker material less susceptible to puncture than the first ply , such as 3 or 4 mil plastic or coated paperboard . a circular puncture port ( 8 ) is provided in the center of the second ply . the second ply is continuously bonded atop the first ply using glue , heat seal , or any other suitable bonding method . the first ply film is exposed to puncture through the circular puncture port ( 8 ), while the remaining area of the first ply film is protected from puncture by the second ply . finally in fig1 the container portion ( 2 ) may have a generally flat bottom ( 4 ), or an angled bottom ( 3 ). the flat bottom ( 4 ) allows the drop - in package to be placed upright on a level surface , while the angle bottom ( 3 ) may promote better flow of the beverage with minimized air gaps when the package is tilted . turning to fig2 a top view of the lid portion ( 7 ) is shown , with the exposed first ply film through the puncture port ( 8 ). fig3 shows a holder ( 30 ) for the drop - in package , which is a generally cylindrical open - mouth bottle ( 31 ) having a threaded portion ( 33 ) around the top of the open - mouth for receiving a dispensing assembly . a cavity ( 32 ) for receiving the drop - in package is of sufficient diameter to allow the container portion ( 2 ) of the drop - in package to freely move in and out of the holder ( 30 ) without mechanical interference , but of small enough diameter to intercept the flange ( 5 ) of the drop - in package around the lip of the holder ( 30 ) just above the threaded portion ( 33 ). this allows the drop - in package ( 2 ) to be easily installed in the holder ( 30 ), with it coming to rest along the flange and the lip of the holder . conversely , the diameter of the drop - in package may be set to an appropriate value so as to allow use of a particular prior art baby bottle as the holder . fig4 a shows the preferred embodiment ( 40 ) of the dispensing assembly . this embodiment is a nipple - type dispensing assembly for use with serving infants and toddlers . it consists of a threaded plastic ring ( 41 ), through which a soft plastic formed nipple ( 42 ) is installed . the threads in the plastic ring ( 41 ) are mating threads to the threaded portion ( 33 ) of the holder . the nipple is provided with one or more orifices through which the liquid beverage may flow when a suction is applied by the nursing infant or toddler . the basic nipple and ring arrangement is well known in the art . added to the well - known arrangement is a puncturing conduit ( 43 ) which punctures the first ply film of the lid portion ( 7 ) of the drop - in package through the puncture port ( 8 ) when the dispensing assembly is screwed onto the top of the holder . in the preferred embodiment of the nipple assembly , puncturing conduit ( 43 ) is shorter than the thread length . this allows the nipple assembly to be placed on the top of the holder , and for the threads to engage prior to the puncturing conduit breaking the package seal . fig4 b shows an alternate embodiment of the nipple assembly , in which the puncturing conduit ( 43 ′) is longer than the depth of the threaded ring depth , which allows the user to puncture the seal on the beverage container prior to threading the nipple assembly onto the holder . the puncturing conduit ( 43 ) is shown in more detail in fig6 . the puncturing conduit ( 43 ) is preferably a single - piece molded rigid plastic device , having a circular disk ( 62 ) with a pointed conduit ( 61 ) centered on the disk ( 62 ) as shown . the length of the pointed conduit ( 61 ) should exceed the diameter of the puncture port ( 8 ) so that when a circular flap of the film is pressed through by the conduit , the flap does not extend far enough towards the pointed end of the conduit so as to be drawn back into the conduit by the liquid flow . the diameter of the pointed conduit must be slightly less than the diameter of the puncture port ( 8 ) to allow it to pass without interference through the port . the puncturing conduit ( 43 ) is installed into the threaded ring ( 41 ) following the nipple ( 42 ). so , the diameter of the circular disk ( 62 ) is preferably set to a value slightly less than the inside diameter of the threads of the threaded ring ( 41 ) so as to allow easy installation and removal of the puncturing conduit but to allow a light friction fit to retain the puncturing conduit in the threaded ring . fig5 shows a straw - type dispensing assembly in which a straw is formed in the assembly rather than a nipple . a single - piece molded plastic device may include a threaded ring ( 51 ) and a flexible straw portion ( 52 ), or this may be constructed of 2 molded plastic pieces . the puncturing conduit ( 43 ″) is installed in the threaded ring ( 51 ) similarly to the nipple - type dispensing assembly , but is much longer to allow access to fluids in the container when the container is held upright instead of inverted . this straw - type assembly is useful for serving perishable fluids to non - infants , such as nutritional supplements to bedridden patients and elderly persons . in fig7 the entire assembly is shown ready for serving , with hidden features shown by dashed lines . the nipple - type dispensing assembly ( 40 ) is installed atop the holder ( 30 ) and engaged at the threaded portion of the holder and the threaded ring . the drop - in package ( 1 ) is captured securely in the assembly , held in place by the flange pinched between the lip of the holder ( 30 ) and the disk of puncturing conduit ( 43 ). the pointed conduit ( 61 ) has punctured the inner seal ( the first ply film ), providing a fluid flow path from the reservoir of the drop - in package ( 1 ) to the nipple of the dispensing assembly . in production , the container portion ( 2 ) of the drop - in package is preferably sterilized using one of many well - known methods , such as the use of hot air . then , a fluid , such as human breast milk or nutritional supplement formula , is poured into the sterilized container portion . the first ply film is then applied and hermetically sealed to the top of the container portion along the flange . the second protective ply of the lid portion ( 7 ) is affixed to the drop - in package . a peel - away protective tab or label may be placed over the circular puncture port . the nipple and straw assemblies may be sterilized and packaged in a plastic or cellophane envelope , as shown in fig8 . this completes the product packaging , and may be followed by appropriate labeling or marking with information such as fluid type , nutritional analysis , production lot trace indicators , directions for use and storage , and an expiration date . while the disclosure contained herein has set forth a preferred embodiment of the invention , and the fundamental mechanical components used within the invention are well known within the art , it will be appreciated by those who are skilled in the art that variations to the combination of elements , materials and steps disclosed can be made without departing from the scope and spirit of the invention .
a disposable , aseptic package for storage and serving of perishable beverages , such as human breast milk . the package is generally cylindrical in shape , the top of which is provided with a circular flange about the circumference of the package , such that the filled package can be dropped down into a cylindrical outer holder . the package is held with its top surface near the top of a holder by the flange . a dispensing assembly , such as a nipple assembly or straw assembly , is mounted atop the holder . as the dispensing assembly is mounted on the holder , a penetrating conduit engages the top surface of the package and punctures it , thereby providing a via for the beverage to flow freely from the package to the dispensing assembly , such as through a nipple or through a straw .
