Sealed crustless sandwich

Asealed crustless sandwichconsists of a filling between two layers of crimp-sealed bread, with the crust removed.
Homemade variations are typically square, round, or triangular; the bread can vary, e.g., white or whole wheat; and the sandwiches can be homemade with common crimping techniques similar topie crust,ravioli, ordumplingsusing readily available kitchen tools (e.g., a fork, small spoon or curved knife end to crimp the edges). A purpose-designed "cut and crimp" tool can also be used.
Mass-produced varieties vary in shape, are typically individually wrapped, frozen and packaged — and include proprietarybrandsas well ashouse brands. They were introduced in 1995 with peanut butter and jelly filling, followed by numerous patentand trademark disputes as well as numerous competitors entering the market.
The sandwiches offer easily-frozen and thawed, ready-to-eat, portable convenience and have been called, "the Swiss Army knife of foods".
Originally developed for as a prepared food for school lunches,they have appeal across generations and can easily be included in a homemade lunch. In 2018, sealed crustless sandwiches were made available to firemen during theCalifornia wildfires.National Football Leagueteams buy tens of thousands of them for players to eat as snacks.
In the United States, mass-produced crustless sealed sandwiches were introduced in 1995, inFargo, North Dakotaby David Geske and Len Kretchman— at the time marketing asIncredible Uncrustablesto schools in the Midwest, with fifty employees making roughly 35,000 of the sealed sandwiches daily by 1998.Their company was purchased byThe J.M. Smucker Companyin 1998.In Japan,Yamazaki Bakinghas marketedLunch Packsealed sandwiches since 1984.
Companies have marketed sealed crustless sandwiches in square, triangular, round and even cloud shapes — with an extensive range of fillings, including ham,cheese,chocolate-hazelnut spread,almond butter and jam,peanut butter and honey,peanut butter and apple butter, peanut butter and banana, sunflower butter and jelly — or, prominently,peanut butterand jelly.In the case of the latter, some companies apply the peanut butter to both interior surfaces of the bread, shielding the bread from the jelly — engineer the bread to prevent filling leaksor augment the crimping withstarchto provide a tighter seal.
Mass-produced U.S. brands include:
Smuckers has plants in KentuckyColoradoand Alabamawith Uncrustables sales projected at $500 million in 2021 — offering numerous variations, e.g.,Grilled Cheese Uncrustable(approximately 2003-2014),Ham and Cheddar Bites,Pepperoni Bitesand others. In 2023, Smucker said it took about ten years to prevent "leaky sandwiches," designing the bread so it doesn't create air pockets and using round loaves.
Chubby Snacks, headquartered in Colorado,launched as adirect-to-consumerbrand in 2020. It markets its sealed sandwiches in a "cloud" shapeusing organic, whole wheat bread; medjool dates and monk fruit for sweetness rather than refined sugar, and having 2-3 grams of sugar per sandwich.The company aimed to manufacture 30 million sealed crustless sandwiches annually by 2024.
Smuckers, with $7.8 billion in net sales as of 2020, has issuedcease and desistletters to any company marketing crustless sealed sandwiches in a round shape, includingsmall businesses, arguing trademark infringement. Targeted companies have included Chubby Snacks,which revised their sandwiches to a cloud shape; Albie's Foodswhich revised theirEZ Jammersto a triangular and later square shape, and Gallant Tigerwhich markets a decidedly adult-flavored product (e.g., chai spiced pear butter and peanut butter) selling at a price-point roughly six times the cost of an Uncrustable.
The Gallant Tiger founder noted that at a time when the company had seven sales outlets, "1,000 followers on Instagram and $20,000 in sales, and [Smuckers was] telling us that not only are we infringing on their trademark, which is a circle-shaped sandwich, but we also were falsifying advertising and essentially slandering them. It was weird. It was almost like in the eyes of Smucker, [Gallant Tiger] was a criminal," adding that a consumer "can tell the difference between Domino's and Pizza Hut [pizza] even though they're both circular food products. So what are we really talking about here?"
TheUnited States Patent and Trademark Officeissued a number of patents for mass-produced versions of a sealed crustless sandwich, which were subsequently reexamined and cancelled for having attempted to patent obvious or well known concepts.
The firstclaimof Menusaver's patent reads:
That is, the patent described a sandwich with a layer of filling in between two pieces of bread which arecrimpedshut and have their crust removed. The other nine claims of the patent elaborate the idea further, including the coating of two sides of the bread with peanut butter first before putting the jelly in the middle, so that the jelly would not seep into the bread—the layers of filling "are engaged to one another to form a reservoir for retaining the second filling in between".
Manyintellectual propertyexperts and members of the general public view this patent as an example of the patent office's inability to properly examine patent applications.The patent examiner cited only seven previous patents issued between 1963 and 1998, and a 1994 book called50 Great Sandwichesthat were deemed relevant to the novelty and nonobviousness of the invention. He concluded that the invention was indeed novel and not obvious and allowed the claims.
After the patent was issued, many more earlier patents and publications were found that teach some or all of the different aspects of the invention. These included a 1949 patent (U.S. patent 2,463,439) that described a device to create these types of sandwiches: "An object of this invention is to provide... a means for locating said filling in the center of the sandwich and sealing the marginal edges of the pieces by heat and pressure to preclude the escape of filling from the finished product... [and] a means for trimming the bakeddoughpieces". These new pieces of prior art were brought to the attention of the patent office through areexaminationproceeding.
The J.M. Smucker Co. also attempted to patent theprocessof making the sandwich in 2004 (rather than just the sandwich itself) and on April 8, 2005, had its application rejected by theU.S. Court of Appeals for the Federal Circuit(CAFC).[1].
In 2001, a small grocery and caterer inGaylord, Michigan, Albie's Food, Inc., was sent acease and desistletter from The J.M. Smucker Co., accusing Albie's of violating their intellectual property rights to the "sealed crustless sandwich". Instead of capitulating, Albie's took the case to federal court, noting in their filings a pocket sandwich with crimped edges and no crust was called a "pasty" and had been a popular dish innorthern Michigansince the nineteenth century. Federal Court determined that Albie's Foods did not infringe on J.M. Smucker Co. intellectual property rights and was allowed to continue.
In March 2001, during the legal proceedings, Albie's filed a request forreexaminationwith theUSPTOasking that the patent be reexamined in light of the newly discoveredprior art. The reexamination serial number is 90/005,949.
In response to the new prior art cited, Smucker's narrowed the wording of their claims to only cover a very specific version of their sealed crustless sandwich. The more narrow claims, for example, only cover sealed crustless peanut butter and jelly sandwiches where the jelly is held between two layers of peanut butter. Nonetheless, in December 2003, the patent examiner rejected the narrowed claims in light of the new prior art.
Smucker's appealed the rejection to theBoard of Patent Appeals and Interferences. In September 2006, the Board reversed the examiner's reasons for rejecting the claims, but found new reasons for rejecting them. They found that the wording in the narrowed claims was too vague to clearly identify exactly what Smucker's is trying to patent. Because Smucker's failed to respond to the Board's rejections within the two-month deadline, the PTO mailed a Notice of Intent to Issue a Reexamination Certificate (NIIRC) in December 2006 cancelling all claims. The reexamination certificate was issued on September 25, 2007.
