Abstract

An expandable microwave popcorn package (1) which contains a charge of popcorn kernels (14) for preparation in a microwave oven. The package (1) is formed of front and back panels (2, 4) preferably joined together at the top and bottom ends by an adhesive and at the sides by side panels (6, 8). The back panel (4) includes a pair of separation lines (18) along which the package material is relatively weak such that a portion (16) of the back panel can be torn from the remainder of the package to expose the popcorn within. Separation lines (18) may be formed by weakening a portion of the bag substrate, by reinforcing the adjacent areas, or by a combination of the two. Side panels (6, 8) are folded to form gussets (7) which allow the package to remain flat during storage, to expand to accommodate the popped kernels. A susceptor (9) is also preferably placed on the front panel (2) opposite the back panel to enhance the popping action.

Description

CONTAINER FOR SERVING AND PREPARING MAIZE ROSES IN MICROWAVES FIELD OF THE INVENTION The present invention relates to an expandable package containing a load of corn rosettes (popcorn) to be prepared in a microwave oven. More particularly, this invention relates to a multi-purpose package which can be converted to a convenient service container after the beans have burst.
BACKGROUND OF THE INVENTION Microwave microwave rosettes have become a popular snack item, with convenience being a major factor in their popularity. Microwave microwave rosettes can be stored in a ready-to-use, stable, leak-proof package or package that serves as a cooking vessel. These containers are designed to store a load of edible ingredients, including grains for REF .: 33151 rosettes of maize, butter and seasonings or optional flavorings, in a folded condition that reduces the required storage space and shipping costs. When these containers are exposed to microwave energy they expand to accommodate the growing volume of the corn rosettes inside. A currently available container that can be used to prepare corn rosettes in a conventional microwave oven is described in US Patent No. 4,571,337 to Cage. This is a traditional, flat-bottomed, squared bag that controls steam ventilation during cooking and allows the top end to open when pulled over diagonally opposite corners. Another common packaging style is the crushed bottom or wedge bottom bag, illustrated in US Pat. No. 4,596,713 to Burdette. In this container the edges of the front and rear panels are joined by two side panels arranged in a flat shape. The upper and lower ends are both sealed by folding. There is no background panel. The inside of the bag is divided into two compartments for food. This container is likewise open at the upper end after cooking to provide access to the contents therein. The ends of the package can be sealed by attaching the edges of each of the panels with a high temperature adhesive-Each side panel includes inward creases that form bevels, which extend into the interior of the package. Prior to cooking, the grain charge and other edible ingredients have a relatively small volume, allowing the bevels to remain folded inward so that the package assumes a relatively flat shape. In addition, since the upper and lower ends remain relatively empty of grains, they are easily flattened and folded over the bulky center section, thereby maintaining the grain charge centered in the intermediate portion of the container. Most microwave microwave rosette containers sold today include a susceptor, which is incorporated into the package panel that rests on the floor of the oven, below the load. The susceptor converts the microwave energy to thermal energy, which begins the process of bursting and introducing steam into the container by causing the first grains to burst. The use of a susceptor generally results in a larger volume of bursting and fewer un-burst grains. The susceptors are sometimes combined with multiple bevels in each side panel for an even larger burst volume. When the still folded container is going to be cooked, it is placed inside the microwave oven with the central section of the front panel resting on the floor of the oven, so that the loading of corn rosettes rests squarely on the susceptor maximum degree. During cooking, the internal pressure of the steam released by the grains and the increased volume of the burst grains causes the two end sections to gradually unfold. As the process continues, the squares also unfold allowing the package to approach its full volume. This process continues until substantially all the grains have burst, or until the first burst grains are in danger of singeing, at which time the container is removed from the oven. The optimum time in the oven depends on the characteristics of the particular oven and the cornstarch grains used, for example, its moisture content.
Traditional packaging leaves something to be desired for the convenience with which you have access to edible corn rosettes. After the corn rosettes have been prepared, one end of the container must be opened, usually by pulling the opposite corners, as described in U.S. Patent No. 4,571,337. Subsequently, the consumer can either empty the contents in a separate serving bowl, or the corn rosettes can be eaten directly from the container. If the consumer does not want to use or does not have a separate container available in which to empty the container, eating directly from the container is a viable but disorganized option. The consumer may not be able to reach the rosettes of corn at the bottom of the container without coming into contact with the shortening or fat that tends to coat the internal surfaces of the container. In addition, if the consumer wishes to add seasonings, such as butter or caramel, to the corn after it burst, it will be very difficult to apply a well-distributed coating through the open end of the container. In view of the foregoing, it should be appreciated - that there is a need for a container of microwave corn rosettes, improved, that can be used not only for storage and preparation of corn rosettes, but which can also be converted to a convenient service container that provides direct and easy access to the edible corn rosettes within it.
BRIEF DESCRIPTION OF THE INVENTION This invention pertains to a multi-purpose microwave popcorn container for storing a load of non-popped corn kernels, which expand to accommodate the increased volume of the corn rosettes as they are blown, in response to the application of microwave energy, and at the end to conveniently serve the resulting edible corn rosettes, without using an additional container. In combination with the other features described below, this package provides increased convenience and cleanliness for the user at a non-significant extra cost. These goals are achieved with a design that is simple and inexpensive to manufacture.
The primary structural components of the package include a front panel, a back panel and two side panels which join the front and rear panels. In a wedge-shaped package, the upper and bottom ends of the front and rear panels can be connected, whereby a closed, sealed package is formed, within which is contained a load of corn rosettes. There are two elongated strips of comparatively low tear resistance, otherwise known as separation lines, extending from the upper end to the bottom end of the back panel. These separation lines divide the back panel into three sections: an intermediate section and two exterior sections. An important feature of this invention is that after the corn has been burst and the package has expanded to accommodate the increased volume, the middle section of the back panel can be easily separated from the rest of the adjacent outside sections. For this purpose, the upper end of each separation line begins with an incision to initiate the tearing or controlled breaking of the posterior panel along these lines. Pulling the upper end of the intermediate section away from the rest of the container causes the rear panel to begin to tear at the base of each incision and continue along the predetermined separation lines. At the end, the intermediate section is detached backwards or completely removed and the container then forms a convenient bowl-shaped container for serving the corn rosettes. In one of the embodiments of the invention, the package includes two outer reinforcing strips adhered to the outer sections immediately adjacent to the separation lines. These reinforcement strips add strength and tear resistance to the linear portions of the back panel to which they are attached. In this wayWhen the intermediate section is pulled from the outer sections, the tear line will be predictably contained between the outer reinforcing strips instead of extending outwardly over the outer sections and the adjacent side panels. Since the outer sections of the back panel will remain intact and will continue to support the side panels, the container will retain its structural integrity and shape after the intermediate section has been removed.
Yet another aspect of the invention relates to two internal reinforcing strips which can work in conjunction with the outer reinforcing strips. These internal strips can be applied to the back panel along the outer edges of the intermediate section. As with the outer reinforcing strips, these internal reinforcing strips increase the strength of the portion of the intermediate section to which they are attached. In this way, a pair of separation lines can be defined between the portions of the front panel that have comparatively greater resistance. The reinforcement strips can be made from tape sensitive to the pressure cut to the length of the back panel. This feature can provide a simple and economical means by which certain areas of the shipment can be reinforced without compromising the integrity of the rear panel itself, as occurs if the panel is intentionally weakened along the separation lines, for example when creating a incision line or perforation line. According to yet another aspect of the invention, a simple strip of reinforcing material can be used to define each separation line by reinforcing the adjacent material. The reduced structural integrity of the separation lines can be achieved by the formation of perforations along the longitudinal center line of the belt. Since the non-perforated portions of the reinforcing strips reinforce the adjacent edges of the middle and outer sections, the breaks will be controlled and will follow the line of the perforations. As with double reinforcement strips, these simple reinforcement strips can be made from pressure sensitive tape. It is also possible, according to the invention, to use partial or complete perforations or incision lines in the rear panel itself, to reduce the strength of the panel along the separation lines. Since the back panel itself thus defines areas of relatively low tear resistance, the package does not require additional reinforcement strips to constitute the adjacent areas. The package may also include a pair of cover strips attached to the back panel on the perforations. These cover strips can prevent the leakage of oils or seasoning through the perforations, and add enough structural stability to ensure that the back panel does not open along the separation lines during handling or while it is expanding. the microwave Owen . Yet another embodiment of the invention combines the advantages of the outer reinforcing strips with incisions in the back panel. The incisions or points adhere to the outer sections immediately adjacent to the intended separation lines, and the incision lines are printed on the back panel immediately adjacent to the inner edges of the strips. Optionally, the package may also include internal reinforcing strips placed along the edges of the intermediate section, adjacent the score lines, as previously described. These arrangements provide redundancy to further ensure that when the intermediate section is removed, the tears will travel along the desired separation lines. Yet another aspect of the present invention utilizes multiple bevels formed by each side panel, to increase burst efficiency and ease of access to the interior of the resulting container. Each side panel is folded to form multiple smaller squares instead of a simple large bevel. Since these smaller bevels extend within the package to a lesser degree, they do not have a tendency to interfere with the bursting process to the same degree as simple bevels. Also, after the middle section has been removed, it will be easier for the consumer to reach the interior of the container without making contact with the side walls, which will probably be coated with lard and seasoning. According to yet another aspect of the invention, the separation lines are located directly adjacent to the internal edges of the bevels. When the container is fed through rollers to bend the folded bevels and seal the ends, and when the container is subsequently handled, the variant thickness in the folding line tends to create natural incision lines or weakened areas along the lines. sections of the front and back panels on this site. Thus, if the separation lines are placed along these natural score lines, there will be less need for additional reinforcement or weakening to form the separation lines. An alternative modality takes advantage of the same natural incision lines by placing the separation lines anywhere between, or if not over, the internal bevel folds. In this way, if the tear deviates from the intended separation line, it will tend to follow the inside edge of a bevel. Another aspect of the present invention is the use of a susceptor to increase the efficiency and integrity of the bursting process. Since the separation lines, the pull tab, etc. they are located on the rear panel, the front panel is free to accommodate the susceptor. Other features and advantages of the present invention will become apparent from the following description of the preferred embodiments, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

DESCRIPTION OF THE PREFERRED MODALITY The present invention relates to an exemplary microwave corn rosette product, generally indicated as 1 in the accompanying drawings. The container 1 contains a load of grains 14 of corn rosettes that expand to form edible, inflated corn rosettes 15 during preparation in a microwave oven. The container 1 can also serve as a container from which the corn rosettes 15 can be conveniently removed and eaten, and which allows users to conveniently add dressings to the prepared corn rosettes, without first removing them from the container. As shown in Figures 1-4, the primary structural components of package 1 include a rectangular front panel 2, a rectangular rear panel 4, and two rectangular side panels 6 and 8 which connect the sides of the front and back panels. Various sheet materials can be used to form the panels, as long as the basic requirements of the container are met. 1. The container can be rigid enough to generally maintain its expanded form without tearing while the corn rosettes are being prepared. , but at the same time it should be flexible enough so that the internal steam and the volume of the corn rosettes can expand the package from its compressed configuration. In addition, the material must be resistant to leaks or stains before, during or after the preparation of the corn rosettes. A two-ply construction with an internal fat-proof layer of 9.07 to 11.34 kg (20 to 25 pounds), and a machine-finished, outer paper layer of 9.07 to 11.34 kg (20 to 25 pounds) is adequate. A suitable material for a single-fold container is a paper of approximately 12.7 to 25.4 μm (0.5 to 1.0 mils) in thickness with a weight of approximately 15.87 to 27.21 kg (35 to 60 lbs). The machine-satin papers are also suitable, but may be too rigid if they are too thick. The paper surface is treated with a commercially available stain inhibitor, fluorocarbon. The four panels define an upper end generally indicated by 10 and a lower end generally indicated by 12. Both ends of the front panel 2 and the rear panel 4 must be joined together to close the container 1 and completely contain them. rosettes of corn 14 and other ingredients. The preferred way to close the ends is to use the 'tube' method in which a heat-sensitive adhesive strip (not shown) is applied to the inner surfaces near both ends of the panels. They are simply placed in a hot press which twists them together at an elevated temperature.The typical adhesives are polyvinyl acetate or polyethylene vinyl acetate, suitable for high temperature applications.An alternative construction for the bottom end of the package 1 includes a panel of additional background (not shown) An example of this type of packaging is described in U.S. Patent No. 4,571,335, which is incorporated by reference herein. However, the tube construction is more compatible with the conversion of the container 1 into a bowl after the bursting has been completed, as explained below. As shown in Figure 4, the side panels 6, 8 of the package 1 include bevels 7 which allow the package 1 to maintain a folded configuration prior to the preparation of the corn rosettes 14. Two bevels 7 are formed in each panel side by creating multiple internal pleats along the longitudinal axis of the container 1, which give the side panel a pleated or accordion-shaped configuration. The rigidity of the side panel material causes the bevels 7 to remain compressed, so that the container 1 remains relatively flat during storage and shipping. When microwave energy is applied, however, the side panel material is flexible enough to allow the bevels 7 to expand to accommodate the increased volume of the expanded corn rosettes 15 (as illustrated in Figures 2-3). ). It is preferred to use two or more bevels 7 on each side, for the reasons explained below. The contents of the package 1 mainly include a load of non-burst grains 14 which expand into burst grains 15 that fill the expanded volume of the package. Also included in the load 14 is a shortening of butter and seasonings to improve the taste and texture of the resulting corn rosettes. The butter or butter stable at room temperature is selected so that refrigeration is not required, and the charge 14 is solid at room temperature. Referring again to the cross-sectional view of Figure 4, this embodiment also includes a susceptor 9 attached to the front panel 2 to improve the operation of the burst. A susceptor is a sheet of thin material, usually formed of a metal, such as aluminum which, when subjected to microwave energy, rapidly increases its temperature, thereby raising the temperature inside the container. The susceptors are important for the bursting efficiency since an ideal container could burst all the grains in the shortest possible time. The mechanics of corn bursting depend on several factors, such as the size of the grains, the thickness of the outer husks of the grains, and the moisture content within the inner portion of the grain. Ideally, all the grains within a particular container fall within a very narrow range of these variables, so that they will all burst at about the same time, thereby preventing the burst grains from being scorched as cooking proceeds. The susceptores. They tend to keep a delay time between the first and last burstings, as soon as possible. These also increase the burst volume and decrease the number of 'not burst. "When the load of the corn kernels 14 has been blown, a rectangular middle section 16 of the rear panel 4 can be removed, thereby forming a container. suitable to conveniently serve the busted corn rosettes 15 (as illustrated in Figure 3). With particular reference to FIGS. 1 and 4, the rear panel 4 includes two spacing lines 18, parallel, located approximately adjacent to the innermost edges of the side panel bevels 7.
These separation lines 18 are narrow strips of material having lower strength than the immediately adjacent packaging material. The purpose of the separation lines 18 is to allow a user to tear the middle section 16 of the rear panel 4 of the container 1, leaving a container usable, with an open top, which retains its shape. If there is an outward deviation from the separation lines 18This could weaken the outer sections 17 and possibly the side panels 6 and 8, thereby greatly reducing the overall structural integrity of the package 1 and causing the package to lose its shape and definition. Alternatively, if it presents a deflected tear on the intermediate section 16 the opening left below may be too small to allow a consumer good access to the interior of the container 1. As shown in Figure 1, the rear panel 4 further includes two incisions small 20 at the upper end of each separation line 18. These incisions serve the double purposes of initiating any tearing of the rear panel 4 along the separation lines 18 and of forming a pull tab 22 from the portion of the rear panel 4 between these. Ideally, the back side of the pull tab 22 has no adhesive applied thereto, so that it remains clear of the front panel 2. In this way, the consumer can use the pull tab 22 to hold the top of the pull tab. intermediate portion 16 when it tears. However, at least some of the adhesive must be applied over the portion of the back panel 4 just below the pull tab 22, so that the end 10 of the container 1 is sealed across its full width. Otherwise, the unpopped grains 14 may escape during storage, or the burst grains 15 and the bond line may escape prematurely during the bursting process. Experimentation has shown that after a container of corn rosettes has expanded to accommodate the burst volume, any breaks or tears initiated along the longitudinal axis of a panel tend to turn outward toward the outer sections of that panel. panel, as well as adjacent panels due to the transverse stresses placed on the container. Thus, if someone wishes to remove only the rectangular intermediate strip 16 from the package 1, guides must be included to direct the tears along the separation lines 18 towards the bottom or bottom end 12 of the package 1. Such guides can be constructed in different ways. The material adjacent to the separation lines 18 can be reinforced relative to the material along the separation lines, the material along the separation lines can be weakened relative to the adjacent material, or the container can include a combination of these structures. Preferably, the separation lines 18 coincide with the internal edges of the folded bevels 7 (as illustrated in Figure 4). The packages tend to be naturally weakened along these lines during the manufacturing and filling process, and possibly during subsequent handling, due to the abrupt change in the thickness of the container, leading to breakage and separation of the fibers. The greater the number of squares, and therefore the greater the difference in thickness, the more pronounced this effect will be. In general, the intercartabon dimension of a simple bevel container will be too small to allow the separation lines to be placed along the bevel edges, so that this construction is not preferred, but can be used. The preferred embodiment of the invention illustrated in Figures 1-4 includes two outer reinforcing strips 24 of the pressure sensitive tape applied to the back panel 14, to reinforce the edges of the outer sections 17 immediately adjacent to the separation lines. intended, and in alignment with the incisions 20. The material that forms the strips of reinforcement 24, and the adhesive that secures the strips, must be able to withstand temperatures up to 177 ° C (350 ° F). Preferred materials for reinforcing strips include polypropylene or oriented polyethylene terephthalate materials (* PET "). Strips 24 are applied to package 1 by tape spouts which wind the tape on the surface of back panel 4 as package passes through the manufacturing machines after the reinforcement strips 24 have been applied to the substrate of the package 1, the additional rollers can be used to apply increased pressure, which ensures adequate adhesion.
The material of the back panel 4 itself is also preferably weakened along the lines of separation 18. This can be achieved by printing incision lines 32 on the material of the back panel adjacent to the outer reinforcing strips 24. These lines of incision 32 will then define the separation lines 18. This redundant arrangement provides additional incentive for the tears to extend along the intended path of the separation lines 18. Yet another embodiment of the present invention illustrated in Figures 11- 14, also includes two internal reinforcing strips 26 of the pressure sensitive tape applied along the edges of the intermediate section 16 adjacent to the desired separation lines 18. In this way, each separation line 18 will be located at a channel formed between the internal and external reinforcement strips that guide and control the tearing action. The incision lines 32 can be added to this embodiment, and similar materials and similar application processes can be used for the internal reinforcement strips 26 as used for the external reinforcement strips 24. Note, however, that the addition of the internal reinforcement strips 26 will not be necessary in most cases. This is because, as described above, the natural tendency is for longitudinal tears in the rear panel 4 to turn outward. In this way, the additional protection provided by the internal reinforcing strips 26 will be used only for relatively high end corn rosette containers. In yet another embodiment of the present invention, illustrated in Figures 5 and 6, a single strip 27 of pressure sensitive tape is applied to the back panel 4 along each separation line 18. These strips 27 are wider than those used in the embodiment described at the beginning, shown in Figure 1-4, so that the edges substantially overlap the adjacent intermediate section 16 and the outer sections 17 forming the remainder of the rear panel 4. A series of perforations 30 it is formed near the center line of each strip 27, thereby weakening the center of the strip relative to the outer portions. The perforations 30 are placed in alignment with, and preferably extend slightly within, the incisions 20, so that when the intermediate section 16 is torn, the tears will be initiated in the incisions and travel along the perforations. Again, these reinforcement strips 27, and the adhesive used to apply them, must be able to withstand relatively high temperatures of up to about 177 ° C (350 ° F). In two other embodiments of this invention, illustrated in Figures 7-10, reinforcement strips are not used at all. Rather, the material of the back panel 4 itself is weakened along the lines of separation 18. This can be accomplished by the use of incision lines 32.
(Figures 7-8) or perforations 31 (Figures 9-10) to define the separation lines 18. The perforations are advantageous since they provide a more significant reduction in resistance, to facilitate tearing, but these also create a possibility that the shortening can be played through them, particularly when it is liquefied under heat. In addition, care must be taken not to weaken the back panel 4 so much that it may slip prematurely during the bursting process or earlier. These problems can be faced by a cover strip 33 which is applied over the perforations 31, as shown in Figures 9-10. A tab can also be included on the end of the cover strip 33 to provide a handle by which the cover strips can be removed prior to tearing the intermediate section 16 of the container 1. When the container 1 is to be used by a consumer, this is placed in a microwave oven with the front panel 2 facing down. As the energy is absorbed by the charge of the grains 14 of corn rosettes, the internal moisture content of the grains is converted to steam, the pressure from which sooner or later the hard outer layer or pericarp of the grains breaks. The soft inner starches will then rapidly expand to form the white fluffy material, commonly known as corn rosettes. Starting and accelerating this process is the susceptor 9 which converts a portion of the microwave energy to heat, to raise the temperature of the grains. As the vapor from the initial bursting grains fills the container 1, the container is forced to expand by straightening and unfolding the bevels 7 of the side panels 6 and 8, creating a vertical space of considerable height above the front panel 2 , to allow the action of free and unrestricted bursting until the package reaches its fully expanded form, as illustrated in Figures 2-3. After the container 1 has been removed from the oven, the consumer can convert it to a service container, since no adhesive was placed between the incisions 20, the pull tab 22 will remain free of the front panel 2. Thus, this it can be used as a handle or handle to pull the upper end 10 of the intermediate section 16 away from the rest of the container 1. This action initiates a tearing action at the base of each incision 20, which follows the separation lines 18 through all the way down the rear panel 4. When the tears reach the adhesive joining the lower ends 12 of the front panel 2 and the rear panel 4, one of several things can happen. The adhesive can give the route such that the bottom end of the intermediate section 16 will be uncoupled from the container 1; the intermediate section can be broken or torn along the side of the adhesive to remove everything except the lower end 12; or the intermediate section 16 can simply remain attached to the rest of the container. Either of these possibilities will provide the consumer with access to the corn rosettes through the opening formed in this way. With the intermediate section 16 removed, the consumer can directly access the interior of the container 1, to take the exposed corn rosettes 15. This is advantageous in comparison to the opening of the package 1 from the upper end 10, since the consumer will have much less contact with the internal surfaces of the package. In addition, the consumer may conveniently add seasonings or dressings to the exposed corn rosettes 15, before eating them. Such seasonings or dressings may include salt, butter, butter substitutes or caramel. Although the invention has been described in detail with reference only to certain embodiments, those skilled in the art will appreciate that various modifications may be made without departing from the spirit of the invention. With such possibilities in mind, the invention is defined with reference to the following claims.
It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention is that which is clear from the present description of the invention.
