DETAILED DESCRIPTION

An embodiment of the present invention comprises a package 10. The package further includes a plurality of compartments 20. The plurality of compartments can be an array of compartments as shown. Each of the compartments 20 is coupled together. A support 18 couples each compartment together. Each of the plurality of compartments forms part of a different one of a plurality of receptacles 34. The receptacles could be directly coupled together without a support. Each compartment 20 is seamlessly coupled to the support 18. Each compartment 20 is seamless and the support 18 is also seamless. Each receptacle is seamless. Each receptacle is seamlessly coupled to the support. The package 16 is seamless. The support 18 and compartments 20 are a mono-block construction. The support 18 and/or the compartments 20 and/or receptacles are flexible and preferably elastomeric. They can be an elastic material such as, silicone, rubber, Ethylene vinyl acetate (EVA) or a composite having elastic and non-elastic material. Each compartment 20 has a respective void space 22 and a respective void space delimiting surface 24. There is a plurality of such surfaces 24. The surfaces 24 are internal surfaces of the package 10. Each delimiting surface 24 has a configuration which follows a 3D outline of a pill shape, such as a tablet, capsule, or caplet shape. Preferably each surface 24 outlines, expect for any area encompassed by a fill entry 26 or fill exit 56, an entire 3D pill shape such as a tablet, capsule, or caplet. In the shown example the delimiting surface 24 of each void space 22 outlines an entire capsule, expect for any area encompassed by a fill entry 26 or fill exit 56. The shape outlined can take any form suitable to be swallowed by a person. In general the void space 22 should have a volume of between 0.7 ml to 4 ml; preferably for a liquid nutrient to be frozen it should be at least 2 ml. The term fluent as used herein is broad enough to include fluid mixed with solids such as a slurry. Fluent is also broad enough to include emulsification. It is also broad enough to include liquid. In general the fluent should have viscosity of no greater than 10,000 centipoise (cP). It could be around 50-500 cP and as little as 0 Cp.

Each receptacle 34 has an external surface 33a, 33b and the delimiting surface from a respective different one of said plurality of delimiting surfaces 24. Each external surface includes a planar portion 33a and 3D portion 33b following a 3D outline of a pill.

Each compartment 20 has a different respective fill entry 26 to fill the compartment 20 with a fluent material which is later frozen. Thus there are a plurality of fill entries 26. Each fill entry 26 provides a different one of said compartments 20 with an entry through which fluent is received. The fluent material in the present example is a slurry of various nutrients such as leafy or chlorophyll, rich greens and, or berries and these nutrients may be blended with water. The fluent may be medicinal such as for diabetes.

In the shown example of FIGS. 1, 2 and 4, each fill entry 26 comprises an elongated gap which opens through the compartment's delimiting surface 24 and the planar external surface 33a of the receptacle of which the compartment form's a part. The portion of the delimiting surface 24 through which the gap opens is at the first end portion 38 of the compartment 20. The gap 36 is elongated along the direction of the compartment's major axis 40. The gap and fill entry has a width measured in the direction of the compartment's minor axis 42 (which is also the direction of the fill entry's minor axis) and is the distance between oppositely facing surfaces 44a, 44b delimiting the fill entry 26. The width is no more than 85% of the width of the compartment measured along the compartment's minor axis 42. The percentage could be less than or equal to 25%. Preferably with a thick form process it is no more than 9% of the width of the compartment. The gap and fill entry has a length measured in the direction of the compartment's major axis 40 (which is also the direction of the fill entry's major axis). The length is no more than 95% of the length of the compartment measured along the compartment's major axis 40. The percentage could be less than or equal to 85% Although each fill entry 26 is shown as a gap it could simply be a slit which opens through the planar external surface 33a of the receptacle 34 and the portion of delimiting surface 24 of the compartment forming the receptacle. The slit would have a closed position wherein the opposite facing surfaces 44a, 44b are in contact with each other and an open position wherein at least a portion of the opposite facing surfaces 44a 44b do not contact each other. In the shown embodiment in FIGS. 1, 2 and 4 each fill entry 26 is only in fluid connection with a different one of each compartment 20.

As stated, each compartment 20 has a first end portion 38 at an end (top) of the compartment along the compartments minor axis 42 which is a first axis. Each compartment also has a second end 48 portion (bottom) along the first axis opposite the compartment's first end portion. Each compartment has a third end portion 50 along the major axis 40 which is a second axis. Each compartment has a fourth end portion 52 opposite its third end and along its second axis.

FIGS. 9 through 18 disclose a packaging 210 having a plurality of fill entries 226 in fluid connection with each other. The packaging is similar to packing 10. A major difference between package 10 and package 210 is that the fill entries 226 and compartments 220 are configured to be in fluid connection as described below. Features in package 210 similar to package 10 are labeled with the same number except a “2” is added as a prefix for each similar item found in packaging 210. Thus fill entries in packaging 210 are listed as 226 as opposed to 26. Many similar features are labeled but not called out. Some similar features are not labeled. Entries 226 are in fluid connection with each other and are along and part of a fluid path 54. The fluid path 54 is unbroken from end to end. The path could be a continuous loop. The packaging 210 also has a plurality of compartments 220 in fluid connection with each other. The fluid path 54 also comprises these compartments. The fluid path also comprises a fluid exit 56 at each compartment. The exits 56 are in fluid connection with each other. The fluid path 54 also comprises fluid connectors 58 fluidly connecting compartments 220 of the fluid path 54. Each fluid connector 58 connects a different one of a pair of compartments 220 which form the fluid path 54. In the shown example at least one of the compartments 220 is a primary compartment 220′ and one of the fill entries is a primary fill entry 226′. The primary fill entry 226′ is the fill entry for the primary compartment 220′. The primary fill entry 226′ and primary compartment 220′ are the entry and compartment making up the fluid path 54 of which no other fill entry 226 or compartment 220 is upstream. The primary fill entry opens through an external surface of the package. The primary fill entry 226′ is the fluid entry through which all fluent flows in the fluid path 54. It flows through the primary entry 226′ first. It flows through the primary entry before flowing to any other to any fill entries 226 in the fluid path 54. The primary compartment 220′ is the compartment through which all fluent flows in the path 54. The primary entry and primary compartment are the first to receive fluent disposed in the packaging 210 relative to all other fill entries 226 and compartments 220 making up the fluid path 54.

In the embodiment shown in FIGS. 9-18 each compartment 220, 220′ has a different one of said plurality of fill entries 226, 226′. Each compartment 220, 220′ has a different one of said plurality of fluid exits 56. Each fill entry 226, 226′ of a compartment is at the compartment's third end 250. Each fluid exit of a compartment 220′, 220 is at the compartment's fourth end 252. Each fluid connector 58 is at and in fluid connection with a different one of said fluid exits 56. It is also at and in fluid connection with a different one of said fill entries 226. Reference 350 and 351 in FIGS. 13 and 14 are pointing to contour lines and are not seams.

The fill entries 26; 226, 226′ in either embodiment can take on a variety of configurations such as a simple through hole. A fill entry having a width along its minor axis such as 62 and a length along its major axis such as 60 should have a fill entry with a width measured along its minor axis which is equal to or less than 85% of the width of its respective compartment wherein the width of the compartment is measured along the compartment's minor axis. Also the at least one fill entry should have a length measured along its major axis 60 that is equal to or less than 95% of the length of the respective compartment wherein the length is measured along the compartment's major axis. The percentages for the width could be much less such as less than or equal to 25%. The percentages of the length could be less such as less than or equal to 85%.

Notably the fill entry could have a largest sectional area which is equal to or less than 25% of the largest sectional area of its compartment 20; 220, 220′ if a thin form process is used and equal to or less than 7% if a thick form process is used. The largest sectional area of the fill entry could be between 55% to 75% of the largest sectional area of the compartment. The sectional area of the fill entry should be measured along a cross section taken along and parallel to a first or second axis of the fill entry 26; 226, 226′. The first and second axis should be perpendicular and intersect. The axis chosen should be the axis on which the length of the fill entry 26; 226, 226′ is the greatest. If no length is greatest than either axis may be chosen. In the shown embodiment the first axis 60 is chosen over the second axis 62. Likewise the cross sectional area of the compartment should be taken along the compartment's 20; 220, 220′ first 42; 242 or second axis 40; 240. The first and second axis of each compartment are perpendicular to each other and intersect with each other. The axis chosen should be the axis along which the length of the compartment is greatest. If no length is greatest than either axis may be chosen. In the shown embodiment in FIG. 4 the second axis 40 is the major axis and is chosen.

To make a package containing frozen nutrient pills, the package 10; 210 is provided. The package 10; 210 has a plurality of the compartments 20; 220, 220′ and fill entries 26; 226, 226′. Each compartment 20; 220, 220′ of said plurality has a different respective one of said plurality of fill entries 26; 226, 226′. Each compartment 20; 220, 220′ has a delimiting surface 24; 224, each delimiting surface of a compartment 20; 220, 220′ outlines a 3D pill shape.

Fluent nutrient is flowed into each of the plurality of compartments 20; 220, 220′ through the compartment's respective fill entry 26; 226, 226′. A fluent dispenser, such as an auto-pipette or mechanical pipette that can transfer measured amounts of a liquid automatically, can be used to flow the fluent.

In one method, each fill entry 26 of the plurality of fill entries 26 is only in fluid connection with a different one of said plurality of compartments 20. Each fill entry 26 is fluidly sealed off from each of the other fill entries 26. Each compartment 20 is fluidly sealed off from each of the other compartments 20. To fill the compartments under this method, a portion of a fluent dispenser is disposed through each fill entry 26. The portion disposed in each fill entry is a slurry. The fluent flows into each compartment from the dispenser.

In another embodiment, the fill entries 226, 226′ are in fluid connection with each other and one of the entries is a primary fill entry 226′. The compartments 220, 220′ are also in fluid connection with each other, and one of the compartments is a primary compartment 220′. In this embodiment fluent flows through primary fill entry 226′ and then from the primary entry 226′ to fill entries 226 of said plurality downstream of said primary entry 226′. Also, fluid flows from the primary compartment 220′ to compartments 220 downstream of the primary compartment.

The packaging with the nutrient is placed in a bag which is sealed. Alternatively a sheet is sealed to the top surface 80 of the packaging to cover the partition surfaces 33a and the fill entries 26. The fluent in the packaging is frozen after the compartments are filled with fluent. The fluent nutrient has a freezing point of from −3 c to −4 c and storage at −18 C.

A person ingests the nutrient as a frozen pill by popping the pill through a pill exit. Each compartment has a pill exit. The pill exit could be the gap 36. It could be the slit, or it could be some other part of a partition portion 32; 232 of the package 10; 210. In this example the frozen pill is a frozen capsule. The frozen pill could also be a frozen tablet. It could also have a caplet shape. The pill exit is a capsule exit when a capsule is formed.

The method further includes contacting a thin elastic sheet 69 preferably made from silicone or rubber to the load bearing support 67 and pill forming portions 65. The method further includes forming the plurality of receptacles 34 coupled to the support 18 from the thin elastic sheet 69 with negative pressure when the sheet 69 is in contact with the load bearing support 67 and pill compartment form portions 65. The forming step further includes forming the plurality of compartments 20 from the sheet 69, each compartment 20 having a different respective void space 22 and a different respective void space delimiting surface 24; each compartment forming part of a different respective one of said receptacles 34. The forming step further includes forming a plurality of fill entries 26 from the sheet 69; a different fill entry 26 of said plurality, opens into a void space 22 of a different respective one said compartments 20. The forming step further includes forming a plurality of exterior undercuts 71 from the sheet; each exterior undercut is delimited by a portion of external surface 33b of a different respective one of said plurality of receptacles 34, and a different respective surface portion 72 of said support 18. The surfaces 72, 33b are seamless with each other. Preferably each exterior undercut is delimited by a connecting surface 73. Each connecting surface 73 is adjacent one of the different respective surfaces 33b of one of the different receptacles 34 and adjacent one of the different respective surface portions 72. The connecting surface 73 is curved and seamless with both the adjacent receptacle surface 33b and support surface 72. The undercut forming surfaces delimit a pocket. The forming step further includes forming a plurality of other undercuts 75 from the sheet 69, each other undercut is delimited by a portion 78 of a void space delimiting surface 24 of a different one of said plurality of compartments 20 and surface 33a of partition 32; it is also preferably delimited by surfaces 44a, 44b delimiting a different one of said fill entries.
