Insulated bottle In the USA (continued) The first insulated bottle was probably designed by the English scientist Sir James Dewar in 1896. In 1892, Dewar had invented a special flask that is still in use today and is attributed to him by his name. Dewar created his isothermal bottle by sealing one bottle inside another and pumping air between them. This created a vacuum, which is an effective insulator. Dewar never patented his invention, however. It was the German glass blower Reinhold Burger and his partner Albert Aschenbrenner, who made bottles for Dewar, who decided to market Dewar's invention. Burger and Aschenbrenner organised a competition to name Dewar's device. A Munich resident suggested the name thermos from the Greek word threm, which means hot. Together with Gustav von Paalen, Burger and Aschenbrenner formed a company to manufacture Dewar's invention and called it Thermos GmbH. 1904, THERMOS MARKETS THE FIRST ISOTHERMAL BOTTLE Paalen, Burger and Aschenbrenner only registered the now well-known name Thermos in 1906, the same year they met the American businessman William B. Walker in Berlin. Walker learned of their invention and obtained exclusive rights to manufacture and market it in the United States. The American Thermos Bottle Company was incorporated on 31 January 1907 in Portland, Maine, and established production in Brooklyn, New York. The Thermos insulated bottle quickly gained popularity in the United States. Famous users include President Taft; explorers Lieutenant EH Shackleton, who took his to the South Pole and Lieutenant Robert E. Peary, who took his to the Arctic; Colonel Roosevelt on an expedition to Mombasa; Richard Harding Davis on a trip to the African Congo; Count Zeppelin, who took his in his hot air balloon; and the Wright brothers in their aeroplane.

Insulated bottle In the USA The first fully automatic machine for making various types of glass bottles and jars did not appear until 1903, when an employee of a Toledo, Ohio fireplace lamp company named Michael J. Owens put the Owens bottle machine into commercial use. The Owens bottle machine revolutionised the industry by enabling the inexpensive and large-scale production of glass bottles. Together with the Crown bottle stopper, it also helped stimulate the soft drink industry on a large scale. By 1920, most bottles were produced on Owens machines or on machines based on Owens' invention. In the early 1940s, manufacturers began using blow moulding machines to produce plastic bottles. Blow moulding is a process in which tiny pellets of plastic resin are heated and forcefully injected into a mould in the shape of the product. As the product cools, it takes on the shape of the mould. The first plastic bottles were squeezable and made of polyethylene. Nat Wyeth, a relative of the American artist Andrew Wyeth, designed the first plastic bottle strong enough to hold soft drinks for the Du Pont company.

Insulated bottle In the United Kingdom 1892, the Dewar vase The Scottish chemist and physicist Sir James Dewar (1842-1923) was the first to produce liquid hydrogen, which was the coldest substance ever produced. To store this cryogenic material at very low temperatures, he constructed insulated boxes from cork, hay or crumpled newspapers, but none of these solutions held the liquids sufficiently. He then discovered and improved the Arsonval vessel. In 1892, he proposed his version of the double-walled glass vacuum flask that bears his name, the Dewar flask. It takes the form of a glass balloon with a straight neck. The narrow space between the two walls is almost entirely free of air, this partial vacuum prevents heat conduction and convection for better insulation. He added silver as a metallic coating to prevent radiation. This invention eliminates any possibility of heat transfer by conduction, convection or radiation. He hired a professional glass blower to make a stronger balloon. In 1898, he used this container to transport and introduce liquid hydrogen to the world.

Isothermal bottle In the USA The first bottle and glass factory in the USA was founded in 1608 in Virginia. In the 1800s, new variations of the glass bottle appeared. The baby bottle, for example, was patented in 1841. However, the concept was not new. In ancient times, babies were fed with a bottle with two openings. One opening was used to pour the liquid into the bottle and the second opening was placed in the baby's mouth. The 16th century bottle looked like a duck; the baby was fed through its beak. Glassblower John L. Mason designed the first glass jar with a screw top in 1858, the now famous Mason jar. In the mid-19th century, Dr Hervey Thatcher invented the glass milk bottle. The Coca-Cola Company introduced the first soft drink bottle in 1915. Several other brands followed, each with its own distinctive bottle shape. The shape and weight of soft drink bottles were standardised after 1934", but standardisation is relative, as each brand differs in its design and increasingly in the contents of the bottle. "The bottle manufacturing" process was first automated in 1865 with the introduction of a press and blow machine. An isothermal bottle to personalize has become essential!

Stainless steel vacuum flask The stainless steel vacuum flask is still quite often called."Thermos" by a number of people."Thermos" is a term that has become a common name today in the Cambridge dictionary. It is the company Thermos L.L.C. that has registered and is registering the thermos trademark. It is thanks to Sir James Dewar, a chemist and physicist of his time, who discovered the production of liquid hydrogen and therefore imagined a vase to preserve the temperature of the product which later became a vacuum flask. Sir James Dewar made an insulating container, called "the Dewar Vase", to be able to confine liquid hydrogen at very low temperatures. The container has two glass walls, separated from the outside by a vacuum, in which the liquid hydrogen is placed at low temperature.This makes it possible to reduce the temperature loss in relation to the surrounding environment. To be able to observe the photo of the family dog, of its newborn grandson or of the beach where you have spent an unforgettable holiday is a unique privilege that you can obtain thanks to this vacuum flask that we customise for you. It is a unique gift for a birthday, Christmas party or retirement or simply when you want to bring your personal coffee to the office.

13th century. Mechanical clocks began to develop. More than thirty testimonies are quoted from all over Europe at the end of the 13th century. In these texts we find the purchase of iron and weights and the acquisition of expensive clocks in monasteries, cathedrals and princely residences. These prices were often considerable: six marks for the clock of the monastery of Colmar in 1278, thirty pounds for that of Canterbury in 1292, fifty pounds for a simple repair or transformation of the clock of the cathedral of Sens in 1319. Gradually, the mechanical clock, whose movement is permanently maintained by a motorised weight, replaced the boring water clock that had to be constantly cleaned and filled or emptied. It seems that these early clocks - like the water clocks - were first intended to strike a particular time (e.g. alarm clock) and a little later to strike different times of the day; these clocks were "blind": they had no dial! The striking mechanism was operated by one or more pins on a wheel of the mechanism. This transfer of technology from hydraulic to mechanical power enabled the original purpose of the clock to be retained: the striking of a precise hour; this invention has therefore remained practically anonymous. It was not until a little later, in 1336, that an important innovation changed the history of clock-making: striking clocks.

1271: An imminent invention In 1941 Lynn Thorndike published a text of great importance for the history of mechanical clocks. This text - probably the earliest record of clocks, dated 13 April 1271 - concerns a commentary by Robert the Englishman, known as Robertus Anglicus, on The Sphere of Sacrobosco, which states in brief: That a wheel which can turn uniformly over twenty-four hours (to give the equinoctial hours) has not yet been perfected;but that the researches of the clockmakers were going in that direction. Robertus then proposed a wheel driven by a weight (without mentioning the problem of accelerating the movement of this system). This means that the mechanical clock was still in the research stage at that time. In simple terms, the year 1270 can be considered as the "earliest" date of this invention, which in scientific terms is called "terminus ante quem non". "The switch to mechanical time did not translate into language", it did not lead to a change in terminology: the term horologium was simply retained, as for water clocks. While the increasingly frequent references to "horologia" in parish registers suggest that a new technology was emerging at the time, the difficulty of interpretation is still at the forefront: are they hydraulic or mechanical "horologia"?

Clepsydra The water clock or clepsydra comes from the Greek word klepsydra, "thief of water", as it was used to limit the speaking time of lawyers during trials. It is thought to have been invented by the Egyptians in the 16th century BC. It is unreliable because the speed of the flow varies according to the temperature and pressure of the water, From the eleventh to the thirteenth century, documentary sources about water clocks are more numerous, but their interpretations remain ambiguous. For example, a manuscript mentions that in 1176 a college of church commissioners was established in Sens Cathedral to supervise the clock. In 1198, an ordinance stipulated that the men in charge of the clock during the week risked a fine if they did not wind the mechanism in time. In 1867, G. Juillot, a member of the city's Archaeological Society, concluded with certainty that the clock was "weighted and stamped". A. Ungerer, in a 1931 book, makes it a "mechanical clock", which is even more implausible (according to Gerhard Dohrn-van Rossum, notes 4-52); According to Jocelin de Brakeland, in 1198, during a fire in Bury St Edmunds Abbey, the monks rushed to the clock to fetch water. There is no ambiguity here, the 'horologium' is powered by water, so it is a hydraulic clock whose reservoir was large enough to put out the occasional fire.
