The Victory of Vacuum Jug Over Plastic Jug

Vacuum jug is the latest in thing now. They are made of stainless steel and assure a spill free usage which makes it safe for storing and serving piping hot liquids as well. But, then again if there are traces of plastic in it, you can simply discard them without a second thought. When liquids come into contact with the plastic, the toxins from them get transferred and it tends to cause many medical issues when it enters the human body.

These jugs are characterised by their tall nature. The lid can be opened to pour the liquid inside it and then fastened securely. Now when you pour, it comes out without a drop of extra spill and the whole process is efficient yet completely effortless. These are an eco-friendly and a much healthier alternative to the commonly used plastic jugs in all places. Some believe that if the liquid is not hot, plastic jugs are a feasible choice. But that is definitely not the case. Anything that comes into contact with plastic is bound to contain traces of the harmful chemicals that the material releases in minute quantities, even if it is supposedly high grade plastic. There might not be any short term effects but when these accumulate inside the body over long periods of time, the results are disastrous and at times irreversible too.

There is one more angle- the cost factor. Yes, definitely plastics are way cheaper than vacuum jugs. But, plastic tends to break easily and of course, there is the unhealthy quotient. The flasks on the other hand come with the assurance of a long serving life. You do not have to worry about it breaking. The vacuum keeps hot liquids warm for a reasonable amount of time. It also preserves the temperature of cold liquids. This means you can enjoy a drink anytime that you want to instead of heating or cooling it every single time.

Adding to this, the long term benefits of china vacuum jug includes stainless steel body, double wall insulation for optimum use and effortless stopper for easy pouring. However the benefits can go long without any hassle but it is important to take good care of the flask. The most important step for effective care is to wash and rinse it well before and after each use. It should stay clean and odor-free all the time and that is possible only with effective cleaning using warm water. This will enhance its longevity and functionality as well.

If you are browsing for a good quality jug, the very first thing that you need to do is to read carefully, each and every feature of the jug and not just go by the highlighted points. It is in the finer details lies the whole essence. Like for example, a company might promise you a superior steel exterior and then in smaller font quote that the inside may contain traces of plastic. Well, there is your catch. If you had ignored reading that, then you would probably have bought it thinking that you were making a healthy choice, while in reality, you actually were not. Marketing is really tricky and if you do not verify properly, well, the loss seems to be yours. If you are buying online, please do take extra precautionary measures because sometimes the images and the actual products might not match.

Quality vacuum jugs are available almost everywhere. You just need to have your eyes open to see that. They can be used at home, in workplaces, for gatherings and outdoor picnics as well. Of course, they come in a variety of sizes and differing shapes, which means you get to pick according to the capacity that you will probably require.

People are becoming aware and are making the intelligent switch. There is a marked change as people are beginning to realize what they are doing to themselves and the environment. Be a part of that change, right now by getting yourself a premium vacuum jug. Just remember to keep all the tips in mind.

Are all Stainless Steel Vacuum Flasks Safe

The concept of nutritious and safe drinks packed in plastic bottles is a total joke, however compelling the advertisements may seem to be. Where there is plastic, you can be sure that there is absolutely no place for health. Also, it causes a lot of environmental damage. It does not decompose and burning plastic releases harmful toxins into the atmosphere. So, what do we do? Switch over to what seems like a healthier choice, the stainless steel flasks. For storing hot beverages like tea and coffee, the stainless steel vacuum flasks are widely in use. These flasks are insulating storage made of stainless steel that mainly functions to increase the length of storage time over which any content stays hot or cool in the flask. But, are they really as safe as they are believed to be? Shockingly not!

They do seem safe; they are not easily breakable, not made of plastic and are advertised to be the best in terms of health consciousness. True, they are safe, but not everything that is up for sale in the name of stainless steel vacuum flask is. Merchants draw profits from the reputation that this flask has among the consumers by using low grade materials on the interior. Some are stainless steel just on the exterior with plastic on the inside. Needless to say, hot liquids and plastic do not make a good combination at all. They cause endless health hazards. There are others that promise of a different interior material but contain a thin sheet of plastic inside. When the liquid is poured into it, little scrapes of plastic peel off and mix with the contents of the flask and it becomes as unhealthy as using plastic bottles.

That is why, when buying one, it is vital that every tiny detail is checked into and verified. Also, if the cap is screw type, that might contain plastic or other harmful polymers, pieces of which tend to fall inside the flask every time it is screwed or unscrewed. Check if the flask is made up of food grade stainless steel, for that is certified to be the safest form of steel to be used in such containers for storing food and liquids to consume with time. Plus, there is a resin inside the flask that is said to keep the liquid hot, make sure that resin is safe too, because sometimes it tends to cause a bad odour that is directly proportional to the heat of the liquid that is poured into the flask. So many hidden hazards even in what is considered safe!

Now, once all this is checked, the statement does ring true. Stainless steel vacuum flasks that are of good quality are definitely the safest; you do not have to worry about the toxins and chemical anymore. But then again, quality is not defined by the price, this is a widespread misconception among most consumers. Price is an indication of the profit the seller wants or the efficiency of his marketing skills. There are decent flasks available at low rates and bad quality ones priced at exorbitant rates and vice versa too. So, instead of judging by the rate, judge it by what is written about the flask on its packaging.

Further to this, it is also important to take all the essential steps for effective care and use. To ensure high level of hygiene and safety make sure that the flask is thoroughly washed with warm water before initial use and pre fill the same before every use. Always make sure to leave some space while filling the content so that the stopper can fit in effectively.

Health comes first, before everything else and that is why it is important to make an informed decision, especially when it comes to containers that are used every single day. If you are planning to buy a stainless steel coffee pot, make an informed decision. Ensure that there are no potentially harmful substances and then open your wallet. An even more important thing is, if you just realized that you have been using an unsafe flask, please discard it. It may seem foolish to throw away a costly product like that but the health issues that it can cause in the long run are a huge price to pay for a simple flask.

Glass Lined Vacuum Flask – 5 Features to Look For

Glass lined flasks are our greatest buddy in the chilly winters and scorching summers. These vacuum flasks keep liquids at a steady temperature. For example, if we pour hot coffee in the flask and seal it, it will remain hot for a long time and similarly, chilled lemonade will stay cool for longer duration if kept in a vacuum flask. But why would we want hot or cold drinks on the go? The thing is that we humans are warm blooded beings and we need to keep our body temperature regulated at nearly 37 degree Celsius. This is the reason why we crave for hot beverages when the outside temperature is below our desired level. Hot drinks help us maintain and increase our body heat in cold temperatures. And this also works in the reverse; when we feel hot, we like to drink cold beverages to lower our body heat.

What are Vacuum Flasks?

Vacuum flasks are also called Dewar bottles or thermos. They are insulated bottles that keep the contents inside at a stable temperature for a long duration of time, irrespective of the surrounding weather conditions. It was invented in the year 1892 by Sir James Dewar and consists of two flasks. One flask is placed inside the other and the air is partly removed from the space between the flasks, generating a near-vacuum, which checks on the heat transfer by conduction or convection.

How do Vacuum Flasks Work?

What will happen if you take a glass of chilled ice tea or a cup of steaming hot coffee and keep them out on the kitchen table? While your coffee will cool down, the ice tea will warm up to the room temperature. This is because if you place any two items with dissimilar temperatures, then the heat transfer will occur and result in both the items to reach the same temperature. Basically vacuum flasks prevent this heat transfer through the walls of the thermos flask.

Five Features of Vacuum Flask to Look Out For

1.  Silver Interiors

You must have noticed a glass casing inside all your vacuum flasks (https://en.wikipedia.org/wiki/Vacuum_flask). This casing is very fragile. It is surrounded by a vacuum and is protected with an outer plastic or metal casing. Usually, you can unscrew and take out this glass envelope for cleaning purposes. Moreover, to decrease infrared radiation, this glass casing is also silvered like a mirror. This entire arrangement of a vacuum and the silver interiors diminishes the heat transfer to a great extent.

2.  Vacuum

Vacuum means the complete absence of atoms in an area. While it is impossible to achieve a complete vacuum, but by removing a major part of air between the two compartments of the thermos, an almost vacuum can be attained. In the absence of these atoms, heat transfer through conduction and convection can be totally eliminated.

3.  Insulated Support

Sometimes large quantities of liquid needs to be stored for temperature maintenance and for this a large and long vacuum flask is used. However, these huge flasks cannot hold the inner container completely just from the neck alone. To solve this and provide better stability, additional supports called spacers are placed between the interior and exterior casing. These spacers also work as a thermal conduit and partly decrease the insulation of the thermos around the region where these spacers link to the interior shell.

4.  Cap

While the walls and bottom of the flask offer proper insulation and prevent heat transfer, the neck or the opening of the thermos does not offer any vacuum. This can affect the temperature of the contents in the flask. To minimize this, a cap or screw-on stopper is used to block the air flow and also to prevent the contents from spilling.

5.  Outer Casing

Though the outer material of the thermos does not play a major role in its insulation effect, but it is still a very critical feature of the glass lined flask. It is very essential that the outer shell of the thermos is made of high grade plastic or metal; otherwise it might crack and shatter unexpectedly. Moreover, the outer casing comes in various colors and designs and you can choose the one that suits your personality and taste.

So, keep these features in mind and go ahead and buy some great glass lined vacuum flasks to beat the heat or treat the winters this season!
