Isothermal bottle Foreword Practical and lightweight, the insulated bottle has revolutionised our consumption and is now as much a part of our daily lives as a handbag or a telephone. It allows you to take your favourite drink wherever you go and keep it at the right temperature all day long. It has evolved a lot over the years: weight, materials, user-friendliness and design. Introduction "Since the invention of the insulated bottle, the question has never been how to keep hot liquids hot and cold liquids cold". The big question is how it works. The answer is: by using foam or vacuum packaging. There is more to an insulated bottle than meets the eye. What we think of as a rigid container is actually a container within a container, with foam or vacuum between the inner wall of the outer container and the outer wall of the inner container. Foam containers keep cold liquids cold and vacuum containers keep hot liquids hot. This method has proven to be very effective since the early 20th century and that is why insulated bottles are popular with anyone who needs or wants to drink liquids on the go, such as athletes, travellers, campers and hikers, or just the average busy person who is thirsty from time to time and has prepared their hot or cold drink in advance. Many baby bottles are also insulated." An isothermal bottle to personalise is now essential! You will find it easily at Gifts-custopolis.com.

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.

History of the clock from its origins to the 16th century, The origins No mechanical clocks seem to exist before the fourteenth century, but several mentions in manuscript sources reveal some of the early history of the clock. The Latin word horologium, horologia, derived from the Greek [ὡρα, time and λέγειν, to say], has been used since Roman antiquity to refer to all time-indicating devices, but the use of this word for all time-measuring instruments hides from us the true nature of their mechanisms. The hydraulic clock A hydraulic clock is an ancient type of clock, which tells the time by allowing a liquid in a container to flow through a small hole. From the beginning, in ancient times, the liquid used was water, hence the name water clock. Later, mercury clocks could be found, especially in Arabic and Chinese writings, but this seems to be anecdotal. The first hydraulic clocks evolved from the simple clepsydra (see the France 2 television game show), to which a more or less sophisticated time indication was added (essentially a graduated scale); over the centuries, we have encountered different types of hydraulic clocks, monumental or not, with sophistications to animate skits, for example, or to strike a precise time.

Mechanical clock A mechanical clock is a time-measuring instrument that tells the time by an originally entirely mechanical action. It is based on the combination of three functions: a driving weight for the rotary movement, a regulator such as a balance wheel and a display (a graduated scale and hands). The mechanical clock is the successor to the various horologia. The Romans, and before them the Egyptians and Greeks, had already developed time-measuring instruments that demonstrated great astronomical knowledge. The invention of the mechanical clock can be placed around the 1300s and appeared in Western Europe at the end of the 13th century. Originally, it was a weight motor and foliot. A foliot is a vertical pendulum that controls the energy supplied to a wheel by a weight. The motion is then transmitted to gears that drive the movement of the hands. A weight suspended from a rope provides energy to the machine, while a system of rods and foliots periodically interrupts the fall of the weight. By placing the weights at each end of the foliot, the rhythm of the back and forth movements can be adjusted. The low precision of this mechanism, from 1 to 2 hours of deviation per 24 hours, renders the minute hand useless, and it will undergo a long evolution and an important diversification over the centuries.

Sundials and obelisks Ancient Egyptian obelisks, built around 3500 BC, are also among the oldest ghost clocks. The oldest known sundial comes from Egypt. It dates from around 1500 BC. Candle clocks The first mention of candle clocks comes from a Chinese poem written in 520 AD. According to this poem, the graduated candle, whose burning rate was measured, was a means of determining the time of night. Similar candles were used in Japan until the early 10th century. Hourglass Hourglasses were the first reliable, reusable, reasonably accurate and easily manufactured time measuring devices. From the 15th century onwards, hourglasses were mainly used to tell time at sea. An hourglass consists of two glass spheres connected vertically by a narrow neck that allows a controlled flow of material, usually sand, from the upper sphere to the lower. Hourglasses are still used today. They were also introduced for use in churches, industry and the kitchen. Candle clocks were another timekeeping device used in the ancient world, from China to England to Mesopotamia. Chronometers were developed in places like India and Tibet and the hourglass (which was widely used throughout Europe) came a little later.

Clocks Since time immemorial, people have tried to tame time. Thanks to scientific discoveries and technical innovations, the measurement of time has gradually been mastered. For thousands of years, people have measured time in a variety of ways, including following the movements of the sun with sundials, using water clocks, candle clocks and hourglasses. Our modern basic 60 time system, a clock with periods of 60 minutes and 60 seconds, dates back to 2000 BC in ancient Sumeria (the southernmost region of ancient Mesopotamia). History of clocks; "Time is money", they say, but the history of clocks is long and fascinating. The measurement of time is one of the earliest developments of mankind and time has changed greatly since ancient times. The birth of clocks to measure time: A clock is a time-measuring instrument that usually tells the time continuously. The word comes from the Latin horologium, "that tells the time", itself derived from the Greek ὡρολόγιον (formed from oρα, "time", and λέγειν, "to tell", λόγιον, "to tell"). Since ancient times, the Latin term 'horologium' has been used to refer to any instrument capable of indicating time, which has often led to difficulties in interpreting ancient texts. Thus, a sundial, a water clock, an astrolabe, a nocturlabe, a mechanical clock were called "horologia". A clock with a photo of your holiday by the sea, in the mountains or in the countryside.
