Description
SPICE PACKAGING SYSTEM
FIELD OF TI{E INVENTION
100011 The present invention relates to tlexible packaging and in particular to flexible packaging of known volumes of herbs, spices and other seasonings.
BACKGROUND OF THE INVENTION
[00021 Spices, both whole and ground spices and herbs, are provided in relatively large containers. These containers can be used multiple tinles and include a volume of spice or spice blend that is suitable for such a large number of recipes that the container would last for years. These containers, however, are not made of materials that are light, air and moisture resistant and do not contain seals that are capable of maintaining these spices in a fresh state for extended periods of time. This results in a substantial degradation in the flavor and aroma of these spices. Typically, a bulk spice in a large container will lose 10% of the aromatic oils per month. Ultimately, the spice will be discarded even after using only a small portion of the total volume in the container. In addition, it may be desired to purchase or carry only enough spice for a single use or two, for example when camping or on vacation. Currently, even the smallest available volumes of spices are not suitable for these uses.
SUMMARY OF THE INVENTION
[00031 The present invention is directed to a spice packaging system in which each spice is provided in multiple small packets, preferably single-use packets of 1-teaspoon size. Each packet keeps the spice fresh and protects the spice from light, air and moisture.
100041 In one embodinient, a spice packaging system is provided that includes a plurality ofpackets such that each packet includes a tlexible packaging material imper-XIous to liglit, gas and moistUu-e, an extei-ior sLn-face, and an enclosed and sealed interior space. The 17exible packaging matcrial can include polyethylene terephthalate or can be a biodegradable material. A knoNvn N-olume of a single certified organic spice, for example one teaspoon or one tablespoon, is contained with the intei-ior space of each packet. This spice can be whole or ground, for example to a grind size of about 1 mm to about 1.5nini. In addition, an inert gas surrounds each known ~'olume of the single certitied organic spice with the interior space. This inert gas is preferably nitrogen. In one embodinlent, the interior space includes two opposing sides, two opposing ends spanning between the sides, and a seal on one of the ends that is capable of being opened to access the interior space and subsequently closed to seal the interior space from light, gas and moisture intrusion.
[00051 In one embodiment, the interior space includes two opposing sides, two opposing ends, a primary seal on one of the ends capable of being opened to access the interior space and sealing the interior space from light, gas and moisture intrusion, and a secondary seal spanning across the interior space from one side to the other and disposed between the two ends, the secondary seal dividing the interior space into two chambers such that an equal portion of the known volume of spice is disposed in each chamber, the secondary seal capable of being selectively ruptured to reunite the two chambers without rupturing the primary seal. In one embodiment, the known volume is about 1 tablespoon, and the interior space further includes two secondary seals dividing the interior space into three chambers, each chamber comprising about 1 teaspoon of the spice. If desired, a grinder capable of grinding the spice and of holding an amount of spice to be ground substantially equivalent to the known volume of spice can be provided in the packaging system.
[00061 The packaging system also includes a method for packaging spices. This niethod includes, forniing a sheet of flexible packaging material into a tube or any other desired shape. In one embodiment, a first end of the tube is scaled, and a desired quantity, e.g., one teaspoon, of a single certihed oi=ganic spice is meastu-ed volumetrically. The desii-ed measured N-olume of spice is introduced into the tube, and a short burst of inel-t gas is introduced into the tube following the introduced volume of spice. The short burst of inert gas has a pressure, flow and duration sufficient to ensure that the entire introduced volume of spice passes into the tube. -l'lie second end of the tube opposite the

Therefore, no foreign substances, additives or preserx atives are used, including anti-caking agents and flow agents that NN=ould enhance the processing of the spicc:s. In addition, the spices are not it-radiated.
4 100171 Referring initially to Figs. 1 and 2, an exeniplaiy embodiment of a spice packaging system 100 in accordance with the present invention is illustrated.
'The system includes a plurality of packets contaiiling the desired spice or spices. One such packet is illustrated. As illustrated, the packet is generally rectangular or elongated in appearance and has a length from about 3" to about 5" and a width up to about 1". Since the package is made of flexible niaterial, the elongated shape can be formed into a generally tubular or cylindrical shape for the purposes of filling the packet with a single spice, a spice blend or a liquid. Other suitable shapes for the packet include spherical shapes, conical or circular shaped and rectangular box shapes.
(00181 Each packet in the plurality of packets is formed from a flexible packaging material impervious to light, gas and moisture. Therefore, spices contained within the package will have a long shelf life of up to ten years or more. Suitable flexible packaging materials include single layer materials and laminates of multiple materials such that each layer in the laminate provides a given type of protection to the contents in the packet. In addition, the layers can be either partially or completely transparent or translucent.
Suitable materials for the flexible packaging include, but are not limited to, polyethylene, polystyrene, polyvinyl chloride, polyamides, polycarbonates, cellulose acetate, coated cellophane, rubber hydrochloride, paper and metal foils such as aluminum foil.
In one embodiment, the flexible packaging material includes polyethylene terephthalate. For example, the flexible packaging can have an inner layer of polyethylene terephthalate (PET) that is in direct contact with the spices and an outer layer of PET or of a material such as cellulose acetate or another layer of polyethylene terephthalate. In addition, an intermediate metal foil layer is disposed between the inner and outer layer.
100191 In one embodinient, a polyi foil, poly laminate is used with the specification "48 Ga PET,'.00035. Therefore, an intermediate foil layer having a thickness of .00035 is sandwiched bet -cen two PET layers. The inner PET layer can be transparent, and the outer PET layer can be opaque and can include colors or other graphics. If desired, the inner PET layer can be omitted. The thickness of the foil layer is the minimum thickness nccessary to proN ide the desired le%,el of protection to the spice contents fi=om air, light or Inolsture. In allother enlbodllllellt, the packaglllg illaterlal is papt:r coated, l.e., llas an exterior paper nlat tinisll. A suitable specification for tllis enlbodiment is 25#paper; 9#PI;.00035Foil;.00015CoexLDPE, which is a 25# paper exterior outer wrap surrounding a 9# PI layer and a.00015 tliick coextruded low density polyethylene interior layer witll the .00035 foil layer sandw-iched between the inner and outer layers. In another embodiment, the packaging material is a brown plastic film laminate with the specification 48gaugePET/10#tan,i.00035Foi1%.0002 metalycine. A 48 gauge PET, tan, outer layer and a .0002 outer metalycine inner layer, which is similar to surlyn, surround the .00035 foil intermediate layer. A paper layer can also be included to give the packaging a mat appearance and to facilitate the addition of printing or graphics. In one embodiment, the packaging material includes a biodegradable material such as a corn starch based polymer. The overall thickness of the packaging material is up to about 100 m and preferably from about 20 m to about 50 m.
[00201 As is best shown in Fig. 6, the packet 102 includes an exterior 602 and an enclosed and sealed interior space 604. A known volume of a single certified organic spice 606 is contained with the interior space of each packet. The spice volume can completely or partially fill the interior space of the packet. In order to preserve the freshness of the spices, any voids between the spice granules as well as any interior space not filled with spice is filled with an inert gas. Therefore, the inert gas surrounds each known volume of the single certified organic spice with the interior space.
Preferably, this inert gas is nitrogen.
[00211 Although the packet, being made of flexible packaging, can be shaped into a generally cylindrical tube, the packet once filled with spice ]las a generally rectangular appearance. In this appearance, the packet and therefore the interior space or pocket, detined by the packet, includes two opposing sides 104 running the length of the interior space. These sides can be formed from bends, folds or creases in the flexile material or fronl heat seals or adhesive bonds. In one embodinlent, the flexible packaging material is a single sheet of nlatcrial that is foi-nled into a tubular shape. A
lengthwise bond 108, for exanlple a heat seal, adhesive bond or physical fold or crinip bond, is provided to forln the tube. In general, suitable nlethods and materials for bonding the flexible material are knowrn and available in the art. The interior space also includes two opposing ends 106.
These ends can be fomied from folds in the material. In addition, one or both ends are initially open, for exaniple to permit filling of the interior space with the single spice or spices and are subsequently sealed using any suitable sealing process. In one enlbodiment, a seal 110 is provided on at least one of the ends. Suitable seals protect the enclosed spices from light, gas and moisture that can degrade the enclosed spices. A
wide variety of seals are available in the art. As illustrated, a seal is provided on both ends of the interior space or packet. In one embodiment, the seal is re-sealable in that the seal is capable of being opened to access the interior space and subsequently closed to seal the interior space from light, gas and moisture intnision. Suitable reclosable seals include a semi-adhesive pressure seal or a "zip-lock" type seal.
[00221 In one embodiment, the end seals include mechanisms to facilitate the opening of the ends to expose the interior space and to access the spice. For example, each seal can contain a perforated line 112 running generally parallel to the end to facilitate tearing off a portion of the end to expose the interior space. Alternatively, each end can include a plurality of notches 114 that are used to start a tear in a direction generally parallel to the sides of the packet, exposing the interior space. Other methods to facilitate tearing the packet open are known and available in the art. In one embodiment, the packet includes different seals and tear mechanisms on either end to provide a different type of dispensing, either controlled or bulk. Alternatively, both ends of the packet have the same or similar seals and tearing mechanisnis. In one embodiment, a spout 116 is provided at one of the ends in communication with the intcrior space. The tearing mechanism opens the spout, which provides flow control when emptying the contents of the interior space.
Each packet can also contain markings including aN-olume niarking 118 to indicate the Volume of the spices or contents of the interior space, a identihcation 120 of the contents of the interior space, e.g., the name of the spice or spice blend, and organic cei-tifications 122 among other niai-kings.
100231 1'he known volume contained within the interior space is chosen in accordance Nvith the contents and the uses to which those contents are put. These volumes can be in English or Metric, i.e., SI, Unlts, including liters, milliliters, cups, cubic centinleters (cc's), tablespoons, teaspoons and fraction thereof. These measurements are provided, however, in volumes as opposed to weights, as that is how the contents, for example spices, are used in recipes. Although larger volumes are possible, the packaging system of the present invention is particularly well suited for use with smaller volumes, for example fractions of a tablespoon, teaspoons and fractions of a teaspoon. A
preferred volume is one teaspoon, as this is a convenient and common volume used in cooking. In addition, this is a small size that minimizes waste. Freshness is preserved since only one packet has to be opened for each teaspoon required. Therefore, other teaspoon packets are not opened, retaining freshness. Freshness contributes to enhanced spice flavor and aroma, improving the quality and taste of the foods prepared using these spices.
100241 In order to provide for larger overall quantities of spices, multiple packets are provided. For example, a plurality of single packets, e.g., three one-teaspoon packets for a total of one tablespoon, are provided in a large package such as a box or carton. These multiple packets can be separate and grouped together or can be joined together as shown, for example, in Fig. 5. When joined together, the plurality of packets can be used together or can be separately, for example by tearing perforations located at different points or along the entire length of two adjacent packets. These packets can be joined along the sides or along the ends. Although illustrated as three packets groups together along the sides, a larger nunlber of packets can also be grouped together. In addition, the grouping of packets, since the packaging material is flexible, can be formed into a roll, and can be placed in a dispenser that allows one packet to be dispensed at a tinle. In one embodinicnt, a plurality of one-teaspoon packets is provided in a box or nietal tin, appropriatelv labeled. The metal tins are stackable and provide additional light and moisture protection for the spices contained in the packets. Each grouping of a plurality of packets can contain the same spice or spice blend. Therefore, different groupings of packets are provided, for example each in its own tin, each having a given spice.
Therefore, an assortment of different spices is provided, and any given spice is available in a packet of a given small size, for example one teaspoon.
100251 Referring to Figs. 3 and 4, in one embodiment, the packet is a segmented package 300. In one enibodinient, the niaterials and general shape of the segmented packet is the same as for the packet containing a single interior space. The segmented packet and, therefore, the interior space of the segmented packet include two opposing sides 302 and two opposing ends 304. At least one of the ends, and preferably both ends, includes a seal 306. In one embodiment, each end seal is a primary seal that is capable of being opened to access the interior space and sealing the interior space from light, gas and moisture intrusion. The primary seals can be re-sealable. In one embodiment, at least one secondary seal 308 is provided that crosses the packet and the interior space between the ends. The secondary seal spans across the interior space from one side to the other and is disposed between the two ends. In one embodiment, a single secondary seal is provided to divide the interior space into two chambers such that an equal portion of the known volume of spice is disposed in each chamber. Alternatively, a plurality of secondary seals 308 are provided that divide the interior space into a plurality of chambers 310 each containing an equal portion or fraction of the spice contained in the interior space. As illustrated, the segmented packet includes two secondary seals 308 that divide the interior space into three chambers. In this embodiment, for example, the known volume is one tablespoon, and each chamber includes one teaspoon of spice.
Volume markings 312 are provided to show the overall volume and chamber volume.
[0026J In one embodiment, each secondary seal is capable of being selectively ruptured to reunite the two chambers adjacent that secondary seal without rupturing either primary seal, which would expose the spices contained within the intei-ior space.
Rupture of the secondary seals can be accomplished, for example, by applying pressure, i.e.
squeezing, one or both of the chambers adjacent the secondary seal. Alternatively stretching foree can be applied to the packet in the area of the secondary seal either parallel or perpendicular to the length of the seal. Rupturing of one of the secondary seals results in a i-cunited chaniber 402 (Fig. 4), and, therefore, a conibining of the volume of spice contained in both cliambers. The contents and spice volume of the reunited cllamber are obtained by tearing the appropriate priniary seal. Therefore, 2 teaspoons can be obtained or fractions, e.g., 1i3, of a teaspoon can be obtained from a single tablespoon or teaspoon without exposing the balance of the tablespoon or teaspoon to light or air that would degrade the spice. The balance of the spice is thus preserved for future use.
The secondaiy seals can be the same type of seal as the primary seal but in a weaker, i.e., thinner configuration. Alternatively, the secondary seals can be different types of seals than the primaiy seals that are selected based upon relative rupture strength.
[00271 In one embodiment, the spice packaging system includes a grinder capable of grinding the spice contained in the packet. The grinder holds an amount of spice to be ground substantially equivalent to the known volume of spice. In one embodiment, the grinder has a one teaspoon capacity. This grinder can be metal, for example stainless steel, plastic, ceramic or combinations thereof. The grinder is useful when whole spices are contained in the packet or when a finer grind is required than the grind size of the spice contained in the packet.
100281 The present invention is also directed to a method for packaging spices.
Referring to Fig. 7, a sheet of flexible packaging material is formed into a tube 702, and a first end 706 of the tube is sealed 704. Suitable methods for forming the tube and sealing an end are available and known in the art. A desired quantity of a single certified organic spice 708 is measured volumetrically. In one embodiment a ring or dish 710 having the desired volume is used and filled with the spice. In one embodiment, this volume is one teaspoon. Since a teaspoon can vary slightly in volume, preferably the teaspoon is about 5ml. The desired volume of spice is changed by changing the dish. In addition, segniented dishes can be used, for exaniple to fill segmented packets. The desired volume of spice is passed through a ti-nnel and introduced into the interior space 710 of the tube 702. A passage betNt,een the dish and funnel is selectively opened and closed.
For example, the top of the funnel can include a plurality of holes, and the bottom of the dish can include a single hole. The dish rotates relative to the fimnel, and the single hole in the bottom of the dish moves sequentially in and out ot'alignnlent with the holes in the 10 fuunel to provide foi- introduction of the spices into the packet. The dish is tilled when the holes are not aligned, providing a continuous tilling niecllanism.
100291 The present invention utilizes snlaller volumes of spice, e.g., 1 teaspoon, and leafy or tacky spices prevent flow problenls for the introduction of the spices into the tube. In addition, the certified organic nature of the spices does not permit the introduction of flow aids. Therefore, a sliort burst of inert gas 712 is directed into the tube following the introduced volume of spice. Preferably, this gas is nitrogen.
The short burst of inert gas has a pressure, flow and duration sufficient to ensure that the entire introduced volume of spice passes into the tube. In addition, the volume of inert gas can be sufficient to substantially fill and inflate the interior space of the packet, providing a cushion-type protection for the spices contained in the packet. The second end 714 of the tube opposite the first end is then sealed (not shown) using any suitable sealing process.
The first and second ends seals and the flexible material are impervious to light, gas and moisture, as described above.
100301 The measured volume of spices can be whole spices or ground spices. In one embodiment, the spices are ground to a grind size of about 1 to about 1.5mm.
In addition to filling a single volume of spice within the tube, multiple portions of the desired volume of spice can be filled into the tube. This yields the segment packet or tube embodiment as described above. In one embodiment, introduction of the measured volume of spice of spice blend into the tube includes introducing separately each one of a plurality of discrete portions of the desired nieasured volume, for example using the segmented dish. Suitable methods for introducing a portion of a measured volume are known and available in the art. A short burst of inert gas is directed into the tube following the introduction of eacll one of the discrete portions of the desired measured Volume. After each short burst and before the introduction of the next portion of the spice, a secondary seal is introduced in the tube betriveen any two poi-tions of the spice in the tube. Each secondary seal is capable of being selectively ruptured to conlbine two adjacent por-tions -ithout rupturing the scals located at the end of the tube. Alternatively, the seals beriveen the portions of the mcasured ~ olume can be the same as the seals on the ends of the tubes. In one embodiment, the desired measured volume is about I
tablespoon, and the plurality of discrete portions is three discreet portions each comprising about 1 teaspoon.
100311 In addition to using the inert gas burst, other steps can be used to facilitate the introduction of the entire measured volume of spice into the tube. In one enibodiment, the tube and filling equipment, e.g., dish and funnel, are vibrated. In addition, the electrostatic properties of the tube, the desired measured volume of spice and the filling equipment are adjusted to facilitate introduction of the desired measured volume into the tube.
100321 While it is apparent that the illustrative enlbodiments of the invention disclosed herein fulfill the objectives of the present invention, it is appreciated that numerous modifications and other embodiments may be devised by those skilled in the art.
Additionally, feature(s) and/or element(s) from any embodiment may be used singly or in combination with other embodiment(s) and steps or elements from methods in accordance with the present invention can be executed or performed in any suitable order.
Therefore, it will be understood that the appended claims are intended to cover all such modifications and embodiments, which would come within the spirit and scope of the present invention.
'The system includes a plurality of packets contaiiling the desired spice or spices. One such packet is illustrated. As illustrated, the packet is generally rectangular or elongated in appearance and has a length from about 3" to about 5" and a width up to about 1". Since the package is made of flexible niaterial, the elongated shape can be formed into a generally tubular or cylindrical shape for the purposes of filling the packet with a single spice, a spice blend or a liquid. Other suitable shapes for the packet include spherical shapes, conical or circular shaped and rectangular box shapes.
(00181 Each packet in the plurality of packets is formed from a flexible packaging material impervious to light, gas and moisture. Therefore, spices contained within the package will have a long shelf life of up to ten years or more. Suitable flexible packaging materials include single layer materials and laminates of multiple materials such that each layer in the laminate provides a given type of protection to the contents in the packet. In addition, the layers can be either partially or completely transparent or translucent.
Suitable materials for the flexible packaging include, but are not limited to, polyethylene, polystyrene, polyvinyl chloride, polyamides, polycarbonates, cellulose acetate, coated cellophane, rubber hydrochloride, paper and metal foils such as aluminum foil.
In one embodiment, the flexible packaging material includes polyethylene terephthalate. For example, the flexible packaging can have an inner layer of polyethylene terephthalate (PET) that is in direct contact with the spices and an outer layer of PET or of a material such as cellulose acetate or another layer of polyethylene terephthalate. In addition, an intermediate metal foil layer is disposed between the inner and outer layer.
100191 In one embodinient, a polyi foil, poly laminate is used with the specification "48 Ga PET,'.00035. Therefore, an intermediate foil layer having a thickness of .00035 is sandwiched bet -cen two PET layers. The inner PET layer can be transparent, and the outer PET layer can be opaque and can include colors or other graphics. If desired, the inner PET layer can be omitted. The thickness of the foil layer is the minimum thickness nccessary to proN ide the desired le%,el of protection to the spice contents fi=om air, light or Inolsture. In allother enlbodllllellt, the packaglllg illaterlal is papt:r coated, l.e., llas an exterior paper nlat tinisll. A suitable specification for tllis enlbodiment is 25#paper; 9#PI;.00035Foil;.00015CoexLDPE, which is a 25# paper exterior outer wrap surrounding a 9# PI layer and a.00015 tliick coextruded low density polyethylene interior layer witll the .00035 foil layer sandw-iched between the inner and outer layers. In another embodiment, the packaging material is a brown plastic film laminate with the specification 48gaugePET/10#tan,i.00035Foi1%.0002 metalycine. A 48 gauge PET, tan, outer layer and a .0002 outer metalycine inner layer, which is similar to surlyn, surround the .00035 foil intermediate layer. A paper layer can also be included to give the packaging a mat appearance and to facilitate the addition of printing or graphics. In one embodiment, the packaging material includes a biodegradable material such as a corn starch based polymer. The overall thickness of the packaging material is up to about 100 m and preferably from about 20 m to about 50 m.
[00201 As is best shown in Fig. 6, the packet 102 includes an exterior 602 and an enclosed and sealed interior space 604. A known volume of a single certified organic spice 606 is contained with the interior space of each packet. The spice volume can completely or partially fill the interior space of the packet. In order to preserve the freshness of the spices, any voids between the spice granules as well as any interior space not filled with spice is filled with an inert gas. Therefore, the inert gas surrounds each known volume of the single certified organic spice with the interior space.
Preferably, this inert gas is nitrogen.
[00211 Although the packet, being made of flexible packaging, can be shaped into a generally cylindrical tube, the packet once filled with spice ]las a generally rectangular appearance. In this appearance, the packet and therefore the interior space or pocket, detined by the packet, includes two opposing sides 104 running the length of the interior space. These sides can be formed from bends, folds or creases in the flexile material or fronl heat seals or adhesive bonds. In one embodinlent, the flexible packaging material is a single sheet of nlatcrial that is foi-nled into a tubular shape. A
lengthwise bond 108, for exanlple a heat seal, adhesive bond or physical fold or crinip bond, is provided to forln the tube. In general, suitable nlethods and materials for bonding the flexible material are knowrn and available in the art. The interior space also includes two opposing ends 106.
These ends can be fomied from folds in the material. In addition, one or both ends are initially open, for exaniple to permit filling of the interior space with the single spice or spices and are subsequently sealed using any suitable sealing process. In one enlbodiment, a seal 110 is provided on at least one of the ends. Suitable seals protect the enclosed spices from light, gas and moisture that can degrade the enclosed spices. A
wide variety of seals are available in the art. As illustrated, a seal is provided on both ends of the interior space or packet. In one embodiment, the seal is re-sealable in that the seal is capable of being opened to access the interior space and subsequently closed to seal the interior space from light, gas and moisture intnision. Suitable reclosable seals include a semi-adhesive pressure seal or a "zip-lock" type seal.
[00221 In one embodiment, the end seals include mechanisms to facilitate the opening of the ends to expose the interior space and to access the spice. For example, each seal can contain a perforated line 112 running generally parallel to the end to facilitate tearing off a portion of the end to expose the interior space. Alternatively, each end can include a plurality of notches 114 that are used to start a tear in a direction generally parallel to the sides of the packet, exposing the interior space. Other methods to facilitate tearing the packet open are known and available in the art. In one embodiment, the packet includes different seals and tear mechanisms on either end to provide a different type of dispensing, either controlled or bulk. Alternatively, both ends of the packet have the same or similar seals and tearing mechanisnis. In one embodiment, a spout 116 is provided at one of the ends in communication with the intcrior space. The tearing mechanism opens the spout, which provides flow control when emptying the contents of the interior space.
Each packet can also contain markings including aN-olume niarking 118 to indicate the Volume of the spices or contents of the interior space, a identihcation 120 of the contents of the interior space, e.g., the name of the spice or spice blend, and organic cei-tifications 122 among other niai-kings.
100231 1'he known volume contained within the interior space is chosen in accordance Nvith the contents and the uses to which those contents are put. These volumes can be in English or Metric, i.e., SI, Unlts, including liters, milliliters, cups, cubic centinleters (cc's), tablespoons, teaspoons and fraction thereof. These measurements are provided, however, in volumes as opposed to weights, as that is how the contents, for example spices, are used in recipes. Although larger volumes are possible, the packaging system of the present invention is particularly well suited for use with smaller volumes, for example fractions of a tablespoon, teaspoons and fractions of a teaspoon. A
preferred volume is one teaspoon, as this is a convenient and common volume used in cooking. In addition, this is a small size that minimizes waste. Freshness is preserved since only one packet has to be opened for each teaspoon required. Therefore, other teaspoon packets are not opened, retaining freshness. Freshness contributes to enhanced spice flavor and aroma, improving the quality and taste of the foods prepared using these spices.
100241 In order to provide for larger overall quantities of spices, multiple packets are provided. For example, a plurality of single packets, e.g., three one-teaspoon packets for a total of one tablespoon, are provided in a large package such as a box or carton. These multiple packets can be separate and grouped together or can be joined together as shown, for example, in Fig. 5. When joined together, the plurality of packets can be used together or can be separately, for example by tearing perforations located at different points or along the entire length of two adjacent packets. These packets can be joined along the sides or along the ends. Although illustrated as three packets groups together along the sides, a larger nunlber of packets can also be grouped together. In addition, the grouping of packets, since the packaging material is flexible, can be formed into a roll, and can be placed in a dispenser that allows one packet to be dispensed at a tinle. In one embodinicnt, a plurality of one-teaspoon packets is provided in a box or nietal tin, appropriatelv labeled. The metal tins are stackable and provide additional light and moisture protection for the spices contained in the packets. Each grouping of a plurality of packets can contain the same spice or spice blend. Therefore, different groupings of packets are provided, for example each in its own tin, each having a given spice.
Therefore, an assortment of different spices is provided, and any given spice is available in a packet of a given small size, for example one teaspoon.
100251 Referring to Figs. 3 and 4, in one embodiment, the packet is a segmented package 300. In one enibodinient, the niaterials and general shape of the segmented packet is the same as for the packet containing a single interior space. The segmented packet and, therefore, the interior space of the segmented packet include two opposing sides 302 and two opposing ends 304. At least one of the ends, and preferably both ends, includes a seal 306. In one embodiment, each end seal is a primary seal that is capable of being opened to access the interior space and sealing the interior space from light, gas and moisture intrusion. The primary seals can be re-sealable. In one embodiment, at least one secondary seal 308 is provided that crosses the packet and the interior space between the ends. The secondary seal spans across the interior space from one side to the other and is disposed between the two ends. In one embodiment, a single secondary seal is provided to divide the interior space into two chambers such that an equal portion of the known volume of spice is disposed in each chamber. Alternatively, a plurality of secondary seals 308 are provided that divide the interior space into a plurality of chambers 310 each containing an equal portion or fraction of the spice contained in the interior space. As illustrated, the segmented packet includes two secondary seals 308 that divide the interior space into three chambers. In this embodiment, for example, the known volume is one tablespoon, and each chamber includes one teaspoon of spice.
Volume markings 312 are provided to show the overall volume and chamber volume.
[0026J In one embodiment, each secondary seal is capable of being selectively ruptured to reunite the two chambers adjacent that secondary seal without rupturing either primary seal, which would expose the spices contained within the intei-ior space.
Rupture of the secondary seals can be accomplished, for example, by applying pressure, i.e.
squeezing, one or both of the chambers adjacent the secondary seal. Alternatively stretching foree can be applied to the packet in the area of the secondary seal either parallel or perpendicular to the length of the seal. Rupturing of one of the secondary seals results in a i-cunited chaniber 402 (Fig. 4), and, therefore, a conibining of the volume of spice contained in both cliambers. The contents and spice volume of the reunited cllamber are obtained by tearing the appropriate priniary seal. Therefore, 2 teaspoons can be obtained or fractions, e.g., 1i3, of a teaspoon can be obtained from a single tablespoon or teaspoon without exposing the balance of the tablespoon or teaspoon to light or air that would degrade the spice. The balance of the spice is thus preserved for future use.
The secondaiy seals can be the same type of seal as the primary seal but in a weaker, i.e., thinner configuration. Alternatively, the secondary seals can be different types of seals than the primaiy seals that are selected based upon relative rupture strength.
[00271 In one embodiment, the spice packaging system includes a grinder capable of grinding the spice contained in the packet. The grinder holds an amount of spice to be ground substantially equivalent to the known volume of spice. In one embodiment, the grinder has a one teaspoon capacity. This grinder can be metal, for example stainless steel, plastic, ceramic or combinations thereof. The grinder is useful when whole spices are contained in the packet or when a finer grind is required than the grind size of the spice contained in the packet.
100281 The present invention is also directed to a method for packaging spices.
Referring to Fig. 7, a sheet of flexible packaging material is formed into a tube 702, and a first end 706 of the tube is sealed 704. Suitable methods for forming the tube and sealing an end are available and known in the art. A desired quantity of a single certified organic spice 708 is measured volumetrically. In one embodiment a ring or dish 710 having the desired volume is used and filled with the spice. In one embodiment, this volume is one teaspoon.

In addition, segniented dishes can be used, for exaniple to fill segmented packets. The desired volume of spice is passed through a ti-nnel and introduced into the interior space 710 of the tube 702. A passage betNt,een the dish and funnel is selectively opened and closed.
For example, the top of the funnel can include a plurality of holes, and the bottom of the dish can include a single hole. The dish rotates relative to the fimnel, and the single hole in the bottom of the dish moves sequentially in and out ot'alignnlent with the holes in the 10 fuunel to provide foi- introduction of the spices into the packet. The dish is tilled when the holes are not aligned, providing a continuous tilling niecllanism.
