- the container 10 is shown in an open position for receiving a baked food product therein.
- the container 10 is designed for housing a baked muffin product for example, but it is contemplated that containers 10 for other baked goods can be provided in accordance with the invention, for transporting, storing and facilitating handling of baked good food products both before and in the retail environment.
- the container 10 may comprise an article-receiving portion 15 , and a lid portion 18 that is hinged to the article-receiving portion 15 via a hinge 12 .
- the hinge 12 may be formed by a series of perforations formed between the article-receiving portion 15 and lid portion 18 , wherein the perforation allow repeated pivotal movement of the lid portion 18 relative to the article-receiving portion 15 without destruction of the attachment therebetween.
- the hinge 12 may alternatively formed as a score line, a crease, or a combination thereof, however, it may be sufficiently strong so as to permit repeated opening and closing and to maintain the structural integrity of the container 10 .
- the article-receiving portion 15 and lid portion 18 both may have formed therein a cavity 16 and 17 respectively, designed to accommodate a particular type of baked good, such as a muffin in the example shown.
- the cavity 16 may be formed to have a shape to accommodate a muffin base portion or baking paper or cup portion of a muffin product, while the lid portion 18 has a cavity 17 to accommodate the upper portion of a muffin product.
- the container 10 is thus designed to house a single-serving baked food product such as a single muffin, or would be alternatively configured to the shape of other baked goods, such as cookies, pastries, cupcakes, breads, bagels or the like.
- other baked goods such as cookies, pastries, cupcakes, breads, bagels or the like.
- such containers 10 would have a article-receiving portion 15 shaped and sized to receive at least a portion of such baked goods, with the lid portion 18 formed to close the article-receiving portion 15 and potentially to accommodate a portion of the baked goods.
- the depth of cavity 16 and upper cavity 17 may also vary depending on the type of food product that is being packaged. For example, if the baked food product is a cookie, the depth of the lower cavity 16 and the upper cavity 17 may not be needed or will be shallower in depth.
- the length and width of the cavities 16 and 17 may also increase as the length or width of the food product increases.
- the lower cavity 16 and the upper cavity 17 may also have ribbed walls, for added support, and to facilitate release of the food product contained therein.
- the lid portion 18 and article-receiving portion 15 are selectively secured to one another in a closed position by a suitable fastening system.
- the lid portion 18 may further comprise a flange portion 19 formed around the cavity portion 17 and an upper fastener mechanism 11 .
- the article-receiving portion 15 may also have a flange portion 20 and a lower fastener mechanism 13 .

- the container 10 is shown in a “closed” position.
- the upper lid portion 18 is selectively folded on top of the lower product containing portion 15 and the connecting portions 11 and 13 attached.
- a skirt 14 is formed as part of each individual package 10 to allow the male connecting portion 13 to be produced on the flange 20 of the article-receiving portion 15 .
- a machine such as a GN machine may be used, wherein the machine processes the plastic material from a flat plastic sheet and forms the male snap feature 13 .
- the machine can't go below the sheet line, so in order to move everything up above sheet line, a taper is provided on the mold, thereby producing the skirt 14 .
- the outer skirt 14 Upon closing of the container 10 , the outer skirt 14 also encompasses the flange 19 of the lid portion 18 , which tends to facilitate retention of the lid portion 18 in the closed position and block moisture, debris, and particles from entering the container 10 when in the closed position.
- a tamper proof seal or arrangement (not shown) in association with the container 10 once the food product is received therein and the container is closed to prevent tampering with the food product before the container is opened by a consumer.
- a tamper evident arrangement in general may be any suitable arrangement which would allow a user to easily detect whether the package for food product 10 has been tampered with.
- Examples of tamperproof arrangements could be an outer shrink wrap/bags, stretch wrap, plastic bags, tapes, heat seals, and any other arrangement as may be desired.
- the male/female connector arrangement is designed such that the female connecting structure 11 and the male connecting structure 13 come together and the female connector 11 elastically deforms around the male connector 13 , such that once mated, the connectors remain connected. Such connection may then be selectively released by a user by pulling up on the lid portion 18 , again causing the female connector to deform and release the male connector.
- Other suitable arrangements may be used to selectively connect the article-receiving portion 15 and lid portion 18 as may be desired.
- the container 10 may be made of a material that is strong enough to hold food products. Plastics such as polyethylene terephthalate, high density polyethylene, polyvinyl chloride, or PVC, low density polyethylene, polypropylene, polystyrene, and other materials for the container 10 will be realized by persons of ordinary skill in the art.
- a package 100 for baked food products may comprise a plurality of individual, single-serving containers 110 , which may be similar to that shown and described in FIGS. 1-3 or other embodiments for example.
- the package for food products is shown at 100 , with the plurality of individual packages for food products 110 being attached by a perforations 119 located between each article-receiving portion 115 .
- the perforations 119 allow for the individual packages for food products 110 to be selectively removed from the other individual containers of package 100 .
- the lid portions 118 have a gap 120 between each container 110 to allow the upper lid portions 118 to bend at a fold line 112 and be connected while the individual containers 110 remain part of the overall package 100 .
- Each individual package for food products 110 may again comprise a fastening system, such as connectors 111 and 113 , which may be similar to that previously described.
- the upper fastener 111 may be a female connecting structure that mates with the lower fastener 113 that may be a male connecting structure.
- the female connecting structure and the male connecting structure are elastically deformable in order to facilitate mating therebetween and remain connected.
- the individual containers 110 may also include a skirt 114 .
- the skirt 114 may also block moisture, debris, and particles from entering the package for food product 100 when the package for food product 100 is in a closed position. Tamperproof systems may also be used with the individual containers 100 in order to easily detect whether the package for food product 100 has been tampered with.
- thermoforming processes may be used in a cost-effective operation to form individual containers 10 .
- a plastic material is provided in a flexible, flat sheet, generally in a large roll form.
- the sheet material is fed into and run as a web through an oven, wherein the material is heated to soften the material.
- the softened material then progresses into a mold station.
- the sheet material is fed into the mold station and is clamped off by a forming die.
- Air is then injected into the mold and it forces that softened material up against the mold contours, and concurrently begins to cool the material down.
- the material thus begins becoming more rigid, not completely rigid but more rigid than when it is initially heated.
- the forming die clamps off the sheet so the air can be introduced, and then after the forming is done, the die also is used to cut the part out of the sheet.
- the forming die is also used to cut in all the perforations in a single forming operation.
- the plurality of individual, single-serving containers 110 are formed by the die configuration to thereby form each of the containers 110 with an article-receiving portion 115 , and a lid portion 118 that is hinged to the article-receiving portion 115 .
- the hinge 112 between the article-receiving portion 115 and lid portion 118 may be formed by perforations which are designed to securely attach the portions while allowing folding of the lid onto the article-receiving portion in a repeatable fashion, without destruction of the hinge perforations.
- Both the article-receiving 115 and lid portions 118 are formed to have the side flanges 121 and 122 respectively, and the respective at least one male and female connecting parts 111 and 113 in a single operation.
- the perforations 119 which connect the individual containers are formed integrally with forming the package in a single operation. The entire package configuration is therefore formed in a single operation, rather than the approach used in the prior art, wherein individual cups of a food product are lidded and perforations are put in afterwards in a secondary operation.
- the connection between the individual, single-serving containers 110 is provided in a fashion to provide secure attachment for shipping, transporting and otherwise handling the package 100 , while allowing for simple and selective detachment of one or more individual containers 100 from the package 100 when desired.
- the perforation scheme is different than between the lid portions and article-receiving portions forming each individual clam-shell container.
- the perforations 119 are formed as micro perforations.
- the micro perforations may be formed in any suitable manner, such as by a steel roll die and a microperf steel roll blade that cuts the micro perforations upon thermoforming of the package.
- the parts are cut with a forged knife, while the micro perforations between the individual containers 110 may be formed using a steel roll blade configuration.
- the micro perforations provide desired strength in terms of retention characteristics between the individual containers 110 , and also provide the desired edge upon selective detachment of the individual containers 110 from the package 100 .
- a ragged edge is produced, which could cut, scratch or otherwise hurt a consumer or other person handling the package 100 or individual container 110 .
- the use of micro perforations avoids the creation of any ragged edges, and produces a nice, fine finished edge which would not have any sharp edges or points that could cause harm to a person handling the package or container.
- micro perforations are such as to produce these qualities, of suitable retention strength as well as a smooth finished edge upon detachment.
- micro perforations whereby small microscopic slits or holes are made in the plastic material, may be formed using a very thin knife blade, and with only small retention tab therebetween, such that upon detachment, the retention tabs do not project from the edge to any significant degree.
- Micro perforations can be achieved in a number of ways, such as ribbon knives, mechanical needle perforation, laser perforation or the like.
- the micro perforations are selectively produced with a predetermined gap and a predetermined frequency of that gap in an inch of roll for example.
- the micro perforations 119 are formed in the range of 10 - 20 perforations per inch, or at about 15 per inch.
- the micro perforations are formed to produce a desired finished edge on each individual container 110 upon being separated to facilitate handling thereof.
- the micro perforations are formed between the skirt portions 114 formed between the individual containers 110 in the package configuration 100 .
- the skirt is formed as part of each individual package to allow the male connecting portion 113 to be produced on the flange 122 of each article-retaining portion 115 .
- a machine such as a GN machine may be used, wherein the machine processes the plastic material from a flat plastic sheet and forms the male snap feature. In the manufacturing operation, the machine can't go below the sheet line, so in order to move everything up above sheet line, a taper is provided on the mold, thereby producing the skirt 114 .
- the knife or other configuration to form the micro perforations in the skirt 114 thus may have a tapered configuration also.
- each individual container may have a tamper evident structure associated therewith, such as a tamper evident tear strip in the part, to facilitate protection of the food product therein, and enhance safety to the consumer.
- a package 150 for baked food products may comprise a plurality of individual, single-serving containers 160 , which may be similar to that shown and described in FIGS. 1-3 or other embodiments for example.
- the package 150 has each of the plurality of individual packages 160 for food products again being attached by perforations 169 located between each article-receiving portion 165 .
- the perforations 169 allow for the individual packages for food products 160 to be selectively removed from the other individual containers of package 150 similar to the embodiment of FIG. 4 .
- the lid portions 168 do not have a gap between each container 160 , but instead are also connected to adjacent upper lid portions 168 by perforations 170 located between each lid portion 168 .
- the perforations 170 allow for the individual packages for food products 160 to be selectively removed from the other individual containers of package 150 similar to the embodiment of FIG. 4 , but also allow all the lid portions to be selectively closed together after the food products are introduced into the article-receiving portions 165 in an automated process.
- the connection therebetween by perforations 170 enable each lid to be moved by movement of only one of the lid portions 168 to the closed position. Thereafter, to consume the food product, the individual containers 160 can be selectively detached by breaking the perforations 169 and 170 connecting the article-receiving portions 165 and lid portions 168 respectively.
- Each individual package for food products 160 may again comprise a fastening system, such as connectors 161 and 163 , which may be similar to that previously described.
- the upper fastener 161 may be a female connecting structure that mates with the lower fastener 163 that may be a male connecting structure.

In various packaging of this type, the lidding material or film is applied and then perforations are produced between the parts in a secondary operation.
- For other types of food products, such as baked goods including muffins, cupcakes, cookies or the like, the products are typically packaged differently. Such types of food products are generally made in batches, and are many times packaged in a larger container with multiple products placed therein. Packaging for such food products has included clam-shell type packages having a bottom tray type section and a closeable top. In other cases, materials such as cellophane may be used to wrap a single baked product up for storage, transport and later consumption for example, but such materials do not provide good protection for the product. It would be desirable to provide packaging that includes selectively separable containers for baked goods, which provide enhanced protection of the food products, while providing single-serving convenience.
- The embodiments of the present invention relate to packaging for food products, particularly for baked goods such as muffins, cookies, pastries, cupcakes, breads or the like.
- In one embodiment, a package for such food products comprising a base or article-receiving portion, and a lid portion that is hinged to the base or article-receiving portion, both portions having side flanges, wherein the flanges are selectively connected to one another to close the article-receiving portion with the lid portion, wherein the article-receiving portion is formed to house a single-serving baked food product. The package may further comprise at least one fastener system formed in association with the flanges to selectively close the lid with the base portion, and the fastener system may also provide reclosability of the lid with the base portion. The base portion may also have at least one stability member extending therefrom to provide stability of the base portion on a surface.
- In another embodiment, the invention relates to a package for food products comprising a plurality of individual, single-serving containers, each of the containers having an article-receiving portion, and a lid portion that is hinged to the article-receiving portion. The plurality of containers are removably attached to one another, to allow each individual, single-serving container to be selectively released from the plurality of containers. Both the article-receiving and lid portions having side flanges which are selectively connected to one another to close the article-receiving portion with the lid portion. In an embodiment, a fastener system may be provided in association with the flanges to allow selective closure of the lid portion with the base portion. The fastener system may comprise a tamper-evident seal in association with the flanges or connecting the lid and base portions, or may comprise a reclosable fastener system. An embodiment of a reclosable fastener system may comprise one of the lid or base portions having at least one male part extending from the flange and one of said portions having at least one corresponding female part formed in the flange to mate with the at least one male part, such that the flanges are selectively connected to one another by the at least one male-female parts to selectively close the article-receiving portion.
- In an embodiment, the single-serving containers provided in a package of a plurality of containers may have the article receiving portions removably attached to at least one adjacent container, and/or the lid portions of adjacent containers may be removably attached to one another. The attachment of the individual, single-serving containers to one another may use perforations between the article receiving and/or lid portions of the containers, wherein the perforations are formed such that upon detachment of the containers from one another, there is not created any sharp or outwardly extending portions in the individual container upon being disengaged from the plurality of containers. For example, the article receiving and/or lid portions may have side flanges releasably connected to one another, and upon disengagement, the exposed edge of the flange portion is relatively smooth.
- In one aspect of the embodiments of the subject invention, the shape of the article-receiving portion and lid portion are selected to conform to the shape of a food product. In another aspect of the embodiments of the invention, the side walls of the article-receiving portion, and optionally the lid portion, are ribbed. In yet another aspect of the embodiments of the subject invention, the at least one fastener system is at least one male part extending from the flange of one portion of the individual container and at least one corresponding female part formed in the flange of the other portion to mate with the at least one male part.
- In manufacture of the plurality of containers, the parts produced with perforations formed between the adjacent containers during production of the containers themselves, thereby not requiring any secondary operation in forming these structures. In accordance with an example, the perforations are formed as micro perforations which upon selective detachment of an individual container form a substantially finished edge, which does not have any portions extending from the edge to any significant degree which could cause harm to a person handling the container or remaining package configuration.
- In another aspect of the invention, a method of packaging baked goods comprises the steps of providing a package having a plurality of containers for food products, with each of the plurality of containers having a first open position and a second closed position and formed to house individual or single-servings of a baked good food product, being formed to have an article-receiving portion, and a lid portion that is hinged to the article-receiving portion, both portions having side flanges and at least one of the portions having at least one fastener system, such that the flanges are selectively connected to one another by the at least one fastener to close the article-receiving portion with the lid portion, wherein the article-receiving portion is formed to house a single-serving baked food product. A baked good food product is positioned in each of the plurality of containers, and each container is closed for packaging of the food products into the closed containers. Thereafter, at least one of the containers is selectively detached from the package for use and consumption of the food product contained in the detached container.

FIGS. 1-3 show an embodiment of anindividual container 10 for an individual or single-serving baked food product. InFIG. 1 , thecontainer 10 is shown in an open position for receiving a baked food product therein. In this example, thecontainer 10 is designed for housing a baked muffin product for example, but it is contemplated thatcontainers 10 for other baked goods can be provided in accordance with the invention, for transporting, storing and facilitating handling of baked good food products both before and in the retail environment. Thecontainer 10 may comprise an article-receivingportion 15, and alid portion 18 that is hinged to the article-receivingportion 15 via ahinge 12. Thehinge 12 may be formed by a series of perforations formed between the article-receivingportion 15 andlid portion 18, wherein the perforation allow repeated pivotal movement of thelid portion 18 relative to the article-receivingportion 15 without destruction of the attachment therebetween. Thehinge 12 may alternatively formed as a score line, a crease, or a combination thereof, however, it may be sufficiently strong so as to permit repeated opening and closing and to maintain the structural integrity of thecontainer 10. The article-receivingportion 15 andlid portion 18 both may have formed therein acavity cavity 16 may be formed to have a shape to accommodate a muffin base portion or baking paper or cup portion of a muffin product, while thelid portion 18 has acavity 17 to accommodate the upper portion of a muffin product. Thecontainer 10 is thus designed to house a single-serving baked food product such as a single muffin, or would be alternatively configured to the shape of other baked goods, such as cookies, pastries, cupcakes, breads, bagels or the like. As with the example shown in the Figs. For a muffin,such containers 10 would have a article-receivingportion 15 shaped and sized to receive at least a portion of such baked goods, with thelid portion 18 formed to close the article-receivingportion 15 and potentially to accommodate a portion of the baked goods. The depth ofcavity 16 andupper cavity 17 may also vary depending on the type of food product that is being packaged. For example, if the baked food product is a cookie, the depth of thelower cavity 16 and theupper cavity 17 may not be needed or will be shallower in depth. The length and width of thecavities lower cavity 16 and theupper cavity 17 may also have ribbed walls, for added support, and to facilitate release of the food product contained therein. - In this example, the
lid portion 18 and article-receivingportion 15 are selectively secured to one another in a closed position by a suitable fastening system. In the example shown, thelid portion 18 may further comprise aflange portion 19 formed around thecavity portion 17 and anupper fastener mechanism 11. The article-receivingportion 15 may also have aflange portion 20 and alower fastener mechanism 13. The fastener mechanism in this example may be a male/female type of locking system, wherein thefastening member 11 could be a female type of locking member and thefastening member 13 could be a male type of locking member. Although a single male/female connector is shown in this example, the article-receivingportion 15 could have a plurality of fastening members such amale locking members 13, with the andlid portion 18 including an equal number offemale locking members 11. To close the container, the two cover members are pivoted into a face-to-face registration in which the male andfemale locking members portions FIG. 3 , thecontainer 10 is shown in a “closed” position. Theupper lid portion 18 is selectively folded on top of the lowerproduct containing portion 15 and the connectingportions - To facilitate forming the male/female connector arrangement shown in this example, in the manufacturing process, a
skirt 14 is formed as part of eachindividual package 10 to allow themale connecting portion 13 to be produced on theflange 20 of the article-receivingportion 15. In an example, a machine such as a GN machine may be used, wherein the machine processes the plastic material from a flat plastic sheet and forms themale snap feature 13. In the manufacturing operation, the machine can't go below the sheet line, so in order to move everything up above sheet line, a taper is provided on the mold, thereby producing theskirt 14. Upon closing of thecontainer 10, theouter skirt 14 also encompasses theflange 19 of thelid portion 18, which tends to facilitate retention of thelid portion 18 in the closed position and block moisture, debris, and particles from entering thecontainer 10 when in the closed position. There may also be provided a tamper proof seal or arrangement (not shown) in association with thecontainer 10 once the food product is received therein and the container is closed to prevent tampering with the food product before the container is opened by a consumer. Such a tamper evident arrangement in general may be any suitable arrangement which would allow a user to easily detect whether the package forfood product 10 has been tampered with. Examples of tamperproof arrangements could be an outer shrink wrap/bags, stretch wrap, plastic bags, tapes, heat seals, and any other arrangement as may be desired. - In this example, the male/female connector arrangement is designed such that the
female connecting structure 11 and themale connecting structure 13 come together and thefemale connector 11 elastically deforms around themale connector 13, such that once mated, the connectors remain connected. Such connection may then be selectively released by a user by pulling up on thelid portion 18, again causing the female connector to deform and release the male connector. Other suitable arrangements may be used to selectively connect the article-receivingportion 15 andlid portion 18 as may be desired. - The
container 10 may be made of a material that is strong enough to hold food products. Plastics such as polyethylene terephthalate, high density polyethylene, polyvinyl chloride, or PVC, low density polyethylene, polypropylene, polystyrene, and other materials for thecontainer 10 will be realized by persons of ordinary skill in the art. - With reference to
FIG. 4 , apackage 100 for baked food products may comprise a plurality of individual, single-servingcontainers 110, which may be similar to that shown and described inFIGS. 1-3 or other embodiments for example. With reference toFIG. 4 , the package for food products is shown at 100, with the plurality of individual packages forfood products 110 being attached by aperforations 119 located between each article-receiving portion 115. Theperforations 119 allow for the individual packages forfood products 110 to be selectively removed from the other individual containers ofpackage 100. Thelid portions 118 have agap 120 between eachcontainer 110 to allow theupper lid portions 118 to bend at afold line 112 and be connected while theindividual containers 110 remain part of theoverall package 100. - Each individual package for
food products 110 may again comprise a fastening system, such asconnectors upper fastener 111 may be a female connecting structure that mates with thelower fastener 113 that may be a male connecting structure. In this example, the female connecting structure and the male connecting structure are elastically deformable in order to facilitate mating therebetween and remain connected. - As in the prior example of
FIGS. 1-3 , theindividual containers 110 may also include askirt 114. Theskirt 114 may also block moisture, debris, and particles from entering the package forfood product 100 when the package forfood product 100 is in a closed position. Tamperproof systems may also be used with theindividual containers 100 in order to easily detect whether the package forfood product 100 has been tampered with. - In manufacture of the individual container of
FIGS. 1-3 or other examples and thepackaging configuration 100 of the invention as an example, thermoforming processes may be used in a cost-effective operation to formindividual containers 10. In a thermoforming process, a plastic material is provided in a flexible, flat sheet, generally in a large roll form. The sheet material is fed into and run as a web through an oven, wherein the material is heated to soften the material. The softened material then progresses into a mold station. In forming thepackage 100 as shown inFIG. 4 , with a plurality of individual, single-servingcontainers 110, the sheet material is fed into the mold station and is clamped off by a forming die. Air is then injected into the mold and it forces that softened material up against the mold contours, and concurrently begins to cool the material down. During the molding process, the material thus begins becoming more rigid, not completely rigid but more rigid than when it is initially heated. The forming die clamps off the sheet so the air can be introduced, and then after the forming is done, the die also is used to cut the part out of the sheet. The forming die is also used to cut in all the perforations in a single forming operation. The plurality of individual, single-servingcontainers 110, are formed by the die configuration to thereby form each of thecontainers 110 with an article-receiving portion 115, and alid portion 118 that is hinged to the article-receiving portion 115. Thehinge 112 between the article-receiving portion 115 andlid portion 118 may be formed by perforations which are designed to securely attach the portions while allowing folding of the lid onto the article-receiving portion in a repeatable fashion, without destruction of the hinge perforations. Both the article-receiving 115 andlid portions 118 are formed to have the side flanges 121 and 122 respectively, and the respective at least one male and female connectingparts perforations 119 which connect the individual containers are formed integrally with forming the package in a single operation. The entire package configuration is therefore formed in a single operation, rather than the approach used in the prior art, wherein individual cups of a food product are lidded and perforations are put in afterwards in a secondary operation. - In the example of the packaging configuration according to the invention, the connection between the individual, single-serving
containers 110 is provided in a fashion to provide secure attachment for shipping, transporting and otherwise handling thepackage 100, while allowing for simple and selective detachment of one or moreindividual containers 100 from thepackage 100 when desired. To enable this, the perforation scheme is different than between the lid portions and article-receiving portions forming each individual clam-shell container. In the example shown, theperforations 119 are formed as micro perforations. In manufacture, the micro perforations may be formed in any suitable manner, such as by a steel roll die and a microperf steel roll blade that cuts the micro perforations upon thermoforming of the package. Typically, in the thermoforming process, the parts are cut with a forged knife, while the micro perforations between theindividual containers 110 may be formed using a steel roll blade configuration. The micro perforations provide desired strength in terms of retention characteristics between theindividual containers 110, and also provide the desired edge upon selective detachment of theindividual containers 110 from thepackage 100. Upon tearing the individual containers apart, if there is too coarse of perforations in between the parts, a ragged edge is produced, which could cut, scratch or otherwise hurt a consumer or other person handling thepackage 100 orindividual container 110. The use of micro perforations avoids the creation of any ragged edges, and produces a nice, fine finished edge which would not have any sharp edges or points that could cause harm to a person handling the package or container. The character of the micro perforations is such as to produce these qualities, of suitable retention strength as well as a smooth finished edge upon detachment. For example, micro perforations, whereby small microscopic slits or holes are made in the plastic material, may be formed using a very thin knife blade, and with only small retention tab therebetween, such that upon detachment, the retention tabs do not project from the edge to any significant degree. Micro perforations can be achieved in a number of ways, such as ribbon knives, mechanical needle perforation, laser perforation or the like. The micro perforations are selectively produced with a predetermined gap and a predetermined frequency of that gap in an inch of roll for example. In an example, themicro perforations 119 are formed in the range of 10-20 perforations per inch, or at about 15 per inch. The micro perforations are formed to produce a desired finished edge on eachindividual container 110 upon being separated to facilitate handling thereof. - In this example, the micro perforations are formed between the
skirt portions 114 formed between theindividual containers 110 in thepackage configuration 100. In the manufacturing process, the skirt is formed as part of each individual package to allow themale connecting portion 113 to be produced on the flange 122 of each article-retaining portion 115. In an example, a machine such as a GN machine may be used, wherein the machine processes the plastic material from a flat plastic sheet and forms the male snap feature. In the manufacturing operation, the machine can't go below the sheet line, so in order to move everything up above sheet line, a taper is provided on the mold, thereby producing theskirt 114. The knife or other configuration to form the micro perforations in theskirt 114 thus may have a tapered configuration also. Alternatively, instead of amale button 113 on the flange 122 formed opposing the clam shell hinge of each individual container, a perimeter snap could be formed along one or both of the side flanges. In addition, each individual container may have a tamper evident structure associated therewith, such as a tamper evident tear strip in the part, to facilitate protection of the food product therein, and enhance safety to the consumer. - An alternative embodiment is shown in
FIG. 5 , wherein apackage 150 for baked food products may comprise a plurality of individual, single-servingcontainers 160, which may be similar to that shown and described inFIGS. 1-3 or other embodiments for example. With reference toFIG. 5 , thepackage 150 has each of the plurality ofindividual packages 160 for food products again being attached byperforations 169 located between each article-receivingportion 165. Theperforations 169 allow for the individual packages forfood products 160 to be selectively removed from the other individual containers ofpackage 150 similar to the embodiment ofFIG. 4 . In this embodiment though thelid portions 168 do not have a gap between eachcontainer 160, but instead are also connected to adjacentupper lid portions 168 byperforations 170 located between eachlid portion 168. Theperforations 170 allow for the individual packages forfood products 160 to be selectively removed from the other individual containers ofpackage 150 similar to the embodiment ofFIG. 4 , but also allow all the lid portions to be selectively closed together after the food products are introduced into the article-receivingportions 165 in an automated process. As each of theupper lid portions 168 bend at afold line 162, the connection therebetween byperforations 170 enable each lid to be moved by movement of only one of thelid portions 168 to the closed position. Thereafter, to consume the food product, theindividual containers 160 can be selectively detached by breaking theperforations portions 165 andlid portions 168 respectively. - Each individual package for
food products 160 may again comprise a fastening system, such as connectors 161 and 163, which may be similar to that previously described. The upper fastener 161 may be a female connecting structure that mates with the lower fastener 163 that may be a male connecting structure. In this example, the female connecting structure and the male connecting structure are elastically deformable in order to facilitate mating therebetween and remain connected. - With reference to
FIGS. 6 and 7 , an alternate embodiment of a individual, single-serving container for baked food products is shown at 200, and may comprise of anupper lid portion 218 and a lower article-receivingportion 215. Thelid portion 218 and article-receivingportion 215 are connected via ahinge 212. Thehinge 212 may be formed by a series of perforations formed between the article-receivingportion 215 andlid portion 218, wherein the perforations allow repeated pivotal movement of thelid portion 218 relative to the article-receivingportion 215 without destruction of the attachment therebetween. Thehinge 212 may alternatively formed as a score line, a crease, or a combination thereof, and may be sufficiently strong so as to permit repeated opening and closing and to maintain the structural integrity of thecontainer 200. The article-receivingportion 215 andlid portion 218 both may have formed therein acavity cavity 216 may be formed to have a shape to accommodate a muffin base portion or baking paper or cup portion of a muffin product, while thelid portion 218 has acavity 217 to accommodate the upper portion of a muffin product. Thecontainer 200 is thus designed to house a single-serving baked food product such as a single muffin, or would be alternatively configured to the shape of other baked goods, such as cookies, pastries, cupcakes, breads, bagels or the like. In this example, thelid portion 218 and article-receivingportion 215 are selectively secured to one another in a closed position by a suitable tamper-evident fastening system. In the example shown, thelid portion 18 may further comprise aflange portion 219 formed around thecavity portion 217, with the article-receivingportion 215 also have aflange portion 220. Theflange portions adhesive seal 222 for example. As an example, a heat seal may be formed to close thelid portion 218 and article-receivingportion 215 after the food product is positioned therein, or an adhesive strip may be provided on one or bothflanges container 200 to allow the container to be closed after the food product is positioned therein. Such a closure could serve as a tamper evident closure wherein any release of the closure would be indicated, or reclosure thereof would not be possible. In such an example, the elimination of the button type of closure in the prior examples may provide for a smaller footprint ofcontainer 200, to provide the ability to stack more containers on a pallet, shelf or the like for efficient storage or shipping. Also in this embodiment, thecontainer 200 may have one ormore stabilizers 224 associated with the article-receivingportion 215 that provide additional stability to thecontainer 200 when positioned on a flat surface, such as on the shelf in a retail environment or during consumption by a consumer. The one ormore stabilizers 224 may be of any suitable configuration, and as shown in this example, could provide extension to the base of the article-receivingportion 215 to prevent tipping thereof. - The containers or packages for food products according to examples of the invention may be made of a material that is strong enough to hold food products. Plastics such as polyethylene terephthalate, high density polyethylene, polyvinyl chloride, or PVC, low density polyethylene, polypropylene, polystyrene, and other materials for the package for food product will be realized by persons of ordinary skill in the art.
- The invention has been described herein with reference to the disclosed embodiments. Obviously, modifications and alterations will occur to others upon a reading and understanding of this specification. It is intended to include all such modifications and alterations insofar as they come within the scope of the appended claims or the equivalent thereof.
