Not-So-Famous Firsts: Food Packaging Edition

Have you ever wondered why Chinese carry-out is packaged in those wire-handled boxes? Or who came up with the idea of squeezing a dollop of ketchup into a foil packet? Read on for answers to these and other pressing questions...

White Gold Storage

The iconic little folded box with a handle wasn't originally designed with Moo Goo Gai Pan in mind. In the early 1900s, fresh oysters were so plentiful along the New England seashore and such a steady source of income for fishermen that they referred to the shelled slimies as "white gold." The average consumer, however, didn't want the mess or hassle involved with shucking oysters, so the savvy fisherman removed the shells from his catch prior to selling. Originally, customers brought their own containers, but the oyster business eventually boomed so much that Bloomer Brothers, a package manufacturer in Newark, New York, began mass-producing a wax-coated cardboard box that could be used as an oyster pail. The little buckets were soon used by vendors as a carry-all for everything from ice cream to live goldfish. Eventually, folded food containers became Bloomer's number one product. Shortly after World War II, Chinese food suddenly exploded in popularity with mainstream America, and the oyster pail became the carton of choice for Asian carry-out. Bloomer Brothers eventually became the Fold-Pak Corporation and is now the largest supplier of Chinese food containers in the United States.

Got Milk Carton?

Unless you lived on a farm in the pre-refrigeration days of the late 19th century and had access to udders, you purchased your milk from the friendly traveling milkman. Using a horse-drawn cart, he ladled out the moo juice from a large open pail into whatever jug or container the customers brought with them to market. This method was both inconvenient and unsanitary; milk tended to slosh and spill as the customer carried it home, and it was often contaminated with the road grit and horse hair that accumulated in the milkman's pail along the route.

The Warren Glass Works Company of Allegheny County, Maryland, patented the first purpose-made glass milk bottle in March 1880. The Warren bottle had a metal bale around the neck that held a protective cap in place. Three years later, Hervey Thatcher, a New York pharmacist, patented a covered milk pail with two sleeve funnels for the sanitary dispensing of milk from the horse cart to the consumer without the milkman having to lift a ladle.

Glass bottles were a definite step forward, but they also had many drawbacks – they were heavy, breakable, and somewhat expensive to produce. G.W. Maxwell patented the first paper milk carton in 1906; the containers were folded and glued by hand, then coated with paraffin wax. Paper cartons weren't an immediate hit. Because they were assembled when shipped from Maxwell's plant, they took up a lot of valuable storage space at the dairy. Ohio toymaker John Van Wormer pondered the problem and, in 1915, patented a "paper bottle" he called Pure-Pak. It was shipped flat and then later assembled and glued at the dairy prior to being filled.

Cookies and Doughnuts and Cakes, Oh My

Quality baked goods used to be sold in white paperboard boxes tied with string, and only someone with X-ray vision knew what the treats within actually looked like. Then in 1959 Martha Entenmann, wife of the son of the Entenmann's bakery founder, had a brainstorm – people were more apt to buy something if they could actually see it. Working with her sons (who'd joined their mom in the family business after serving in the Korean War), she developed the first cake box with a plastic "window." The new box allowed the company to display its product on standard supermarket shelves, rather than relying on the limited "under glass" space available in independent bakeries. Instead of taking a number and waiting for a busy salesperson, consumers could browse among all the various "see-through" boxes of Entenmann's chocolate chip cookies, powdered doughnuts, and crumb cakes (a favorite of Frank Sinatra) at their leisure before making a choice. Or two.

Portable Ketchup


Ketchup has been America's favorite condiment since the early 1800s, so it stands to reason that most of us think of ketchup packets as having been around "forever." However, the individual foil "sachet" (the industry term for a condiment packet) is much younger than you'd think – it was patented in May 1955 and wasn't widely used until 1968, when Heinz started packaging its ketchup thusly and selling it in bulk to the food service industry. Prior to that time, military personnel were given dehydrated ketchup powder in their field rations, ballpark vendors adorned hot dogs from condiment tubs on their trays before passing them down to the customer, and drive-in restaurants brought full-size bottles to the cars requesting ketchup.

Don't Expect a Laugh When You Crack a Yolk

The egg may be considered by some to be nature's perfect food, but unfortunately nature hadn't considered the logistics involved in shipping eggs in bulk when she devised that fragile shell to contain her precious nutrients. When transporting fresh eggs to market, farmers attempted to cushion their cargo with towels and newspapers, but the bumpy and pitted dirt roads of the 1800s made it nearly impossible for an egg shipment to arrive completely intact.

Joseph Coyle made his living as the founder and editor of the local newspaper in Smithers, British Columbia, but he also had a passion for inventing things. One morning in 1911, he was dining at the Aldermere Hotel when he overheard a heated argument between the hotel owner and the farmer who'd just delivered a shipment of mostly broken eggs. Coyle's mental gears began turning, and he returned to his office with one purpose in mind – to invent a better way to transport eggs. Later that year he patented the "Coyle Egg-Safety Carton," a carrier made of stiffened paper that had a separate "dimple" for each egg. Coyle made his cartons by hand for several years, but demand grew and sales were so strong that by 1919 he was able to build a mechanized factory to produce his egg cartons.

There’s a minute, and then there’s a hot minute. Defined as “a longish amount of time,” this unit of time is familiar to Alabamians but may stir up confusion beyond the state’s borders.

It’s Louisianans, though, who feel the “most misunderstood,” according to the results of a survey regarding regional slang by PlayNJ. Of the Louisiana residents surveyed, 72 percent said their fellow Americans from other states—even neighboring ones—have a hard time grasping their lingo. Some learned the hard way that ordering a burger “dressed” (with lettuce, tomato, pickles, and mayo) isn’t universally understood, nor is the phrase “to pass a good time” (instead of “to have” a good time).

After surveying 2000 people (with proportional numbers from each state), PlayNJ created a map showing the top slang word in each state. Many are words that are unlikely to be understood beyond state lines, but others—like California’s bomb (something you really like) and New York’s deadass (to be completely serious)—have spread well beyond their respective borders thanks to memes and internet culture.

Hawaiians are also known for their distinctive slang words, with 71 percent reporting that words like shaka (hello) and poho (waste of time) are frequently misunderstood. Shark bait, one of the state’s more colorful terms, refers to tourists who are so pale that they attract sharks.

Check out the full list below and test your knowledge of regional slang words with PlayNJ’s online quiz.

The Body
10 Facts About the Appendix

Despite some 500 years of study, the appendix might be one of the least understood structures in the human body. Here's what we know about this mysterious organ.

1. THE ANCIENT EGYPTIANS CALLED IT THE "WORM" OF THE BOWEL.

The human appendix is small, tube-shaped, and squishy, giving ancient Egyptians, who encountered it when preparing bodies for funerary rites, the impression of a worm. Even today, some medical texts refer to the organ as vermiform—Latin for "worm-like."

2. THE APPENDIX SHOWS UP IN LEONARDO DA VINCI’S DRAWINGS.

The earliest description of a human appendix was written by the Renaissance physician-anatomist Jacopo Berengario da Carpi in 1521. But before that, Leonardo da Vinci is believed to drawn the first depiction of the organ in his anatomical drawings in 1492. Leonardo claimed to have dissected 30 human corpses in his effort to understand the way the body worked from mechanical and physiological perspectives.

3. IT'S ABOUT THE SIZE OF A PINKY FINGER.

The appendix is a small pouch connected to the cecum—the beginning of the large intestine in the lower right-hand corner of your abdomen. The cecum’s job is to receive undigested food from the small intestine, absorb fluids and salts that remain after food is digested, and mix them with mucus for easier elimination; according to Mohamad Abouzeid, M.D., assistant professor and attending surgeon at NYU Langone Medical Center, the cecum and appendix have similar tissue structures.

4. CHARLES DARWIN THOUGHT IT WAS A VESTIGIAL ORGAN …

The appendix has an ill-deserved reputation as a vestigial organ—meaning that it allegedly evolved without a detectable function—and we can blame Charles Darwin for that. In the mid-19th century, the appendix had been identified only in humans and great apes. Darwin thought that our earlier ancestors ate mostly plants, and thus needed a large cecum in which to break down the tough fibers. He hypothesized that over time, apes and humans evolved to eat a more varied and easier-to-digest diet, and the cecum shrank accordingly. The appendix itself, Darwin believed, emerged from the folds of the wizened cecum without its own special purpose.

5. … BUT THE APPENDIX PROBABLY EVOLVED TO HELP IMMUNE FUNCTION.

The proximity and tissue similarities between the cecum and appendix suggest that the latter plays a part in the digestive process. But there’s one noticeable difference in the appendix that you can see only under a microscope. “[The appendix] has a high concentration of the immune cells within its walls,” Abouzeid tells Mental Floss.

Recent research into the appendix's connection to the immune system has suggested a few theories. In a 2015 study in Nature Immunology, Australian researchers discovered that a type of immune cells called innate lymphoid cells (ILCs) proliferate in the appendix and seem to encourage the repopulation of symbiotic bacteria in the gut. This action may help the gut recover from infections, which tend to wipe out fluids, nutrients, and good bacteria.

For a 2013 study examining the evolutionary rationale for the appendix in mammal species, researchers at Midwestern University and Duke University Medical Center concluded that the organ evolved at least 32 times among different lineages, but not in response to dietary or environmental factors.

The same researchers analyzed 533 mammal species for a 2017 study and found that those with appendices had more lymphatic (immune) tissue in the cecum. That suggests that the nearby appendix could serve as "a secondary immune organ," the researchers said in a statement. "Lymphatic tissue can also stimulate growth of some types of beneficial gut bacteria, providing further evidence that the appendix may serve as a 'safe house' for helpful gut bacteria." This good bacteria may help to replenish healthy flora in the gut after infection or illness.

6. ABOUT 7 PERCENT OF AMERICANS WILL GET APPENDICITIS DURING THEIR LIFETIMES.

For such a tiny organ, the appendix gets infected easily. According to Abouzeid, appendicitis occurs when the appendix gets plugged by hardened feces (called a fecalith or appendicolith), too much mucus, or the buildup of immune cells after a viral or bacterial infection. In the United States, the lifetime risk of getting appendicitis is one in 15, and incidence in newly developed countries is rising. It's most common in young adults, and most dangerous in the elderly.

When infected, the appendix swells up as pus fills its interior cavity. It can grow several times larger than its average 3-inch size: One inflamed appendix removed from a British man in 2004 measured just over 8 inches, while another specimen, reported in 2007 in the Journal of Clinical Pathology, measured 8.6 inches. People with appendicitis might feel generalized pain around the bellybutton that localizes on the right side of the abdomen, and experience nausea or vomiting, fever, or body aches. Some people also get diarrhea.

7. APPENDECTOMIES ARE ALMOST 100 PERCENT EFFECTIVE FOR TREATING APPENDICITIS.

Treatment for appendicitis can go two ways: appendectomy, a.k.a. surgical removal of the appendix, or a first line of antibiotics to treat the underlying infection. Appendectomies are more than 99 percent effective against recurring infection, since the organ itself is removed. (There have been cases of "stump appendicitis," where an incompletely removed appendix becomes infected, which often require further surgery.)

Studies show that antibiotics produce about a 72 percent initial success rate. “However, if you follow these patients out for about a year, they often get recurrent appendicitis,” Abouzeid says. One 2017 study in the World Journal of Surgery followed 710 appendicitis patients for a year after antibiotic treatment and found a 26.5 percent recurrence rate for subsequent infections.

8. AN INFECTED APPENDIX DOESN’T ACTUALLY BURST.

You might imagine a ruptured appendix, known formally as a perforation, being akin to the "chestbuster" scene in Alien. Abouzeid says it's not quite that dramatic, though it can be dangerous. When the appendix gets clogged, pressure builds inside the cavity of the appendix, called the lumen. That chokes off blood supply to certain tissues. “The tissue dies off and falls apart, and you get perforation,” Abouzeid says. But rather than exploding, the organ leaks fluids that can infect other tissues.

A burst appendix is a medical emergency. Sometimes the body can contain the infection in an abscess, Abouzeid says, which may be identified through CT scans or X-rays and treated with IV antibiotics. But if the infection is left untreated, it can spread to other parts of the abdomen, a serious condition called peritonitis. At that point, the infection can become life-threatening.

9. SURGEONS CAN REMOVE AN APPENDIX THROUGH A TINY INCISION.

In 1894, Charles McBurney, a surgeon at New York's Roosevelt Hospital, popularized an open-cavity, muscle-splitting technique [PDF] to remove an infected appendix, which is now called an open appendectomy. Surgeons continued to use McBurney's method until the advent of laparoscopic surgery, a less invasive method in which the doctor makes small cuts in the patient's abdomen and threads a thin tube with a camera and surgical tools into the incisions. The appendix is removed through one of those incisions, which are usually less than an inch in length.

The first laparoscopic appendectomies were performed by German physician Kurt Semm in the early 1980s. Since then, laparoscopic appendectomies have become the standard treatment for uncomplicated appendicitis. For more serious infections, open appendectomies are still performed.

10. AN APPENDIX ONCE POSTPONED A ROYAL CORONATION.

When the future King Edward VII of Great Britain came down with appendicitis (or "perityphlitis," as it was called back then) in June 1902, mortality rates for the disease were as high as 26 percent. It was about two weeks before his scheduled coronation on June 26, 1902, and Edward resisted having an appendectomy, which was then a relatively new procedure. But surgeon and appendicitis expert Frederick Treves made clear that Edward would probably die without it. Treves drained Edward's infected abscess, without removing the organ, at Buckingham Palace; Edward recovered and was crowned on August 9, 1902.

11. THE WORLD'S LONGEST APPENDIX MEASURED MORE THAN 10 INCHES.

On August 26, 2006, during an autopsy at a Zagreb, Croatia hospital, surgeons obtained a 10.24-inch appendix from 72-year-old Safranco August. The deceased currently holds the Guinness World Record for "largest appendix removed."
