How a Glass Bottle is Made

Le 17 April 2018, 10:08 dans Humeurs 0

A bottle is deciphered as an unyielding container which has a neck, a body and mouth. The neck is more slender than the body. Historical books have indicated that it was the Phoenicians who first fashioned glass bottles, mainly to store perfume or other fragrant liquid compositions. The Phoenicians then taught the Romans the fine art of making thermos food flasks , and they manufactured many versions for various uses.

The production of bottles made of glass is of two categories, from sheet glass and from glass- container glass. Modern bottle plants break down their operations into 3 major parts: -

i) The batch house takes care of all raw materials
ii) The hot end handles the manufacturing side of ovens, furnaces and forming machines
iii) The cold end takes care of inspection and packaging

When the batch house has sorted through all the raw materials, the hot end process takes over by forming the molten glass into respective containers. Each batch is fed into the furnace at rates which are controlled, depending on the glass composition.

To produce thermos food jar, modern plants use two methods, either by the blow and blow process or the press and blow technique. Both these progressions involve the cutting of a stream of molten glass with a clipping blade to form glass cylinders, known as gob. Blank moulds are filled with gob, which falls delicately into the moulds through chutes and troughs. Utilising the blow and blow process, the glass is primarily blown from underneath into the blank moulds to manufacture a pre-container, or pre-bottle. This pre-container is then turned over into a last mould. A concluding blow is rendered, and the glass is made into its designed shape. In the press and blow method, the pre-bottle is shaped with a plunger made of metal. It thrusts the glass out into the blank mould.

Now comes the forming machines which hold and shifts the components that structures the bottle. These bottles are made via time-coordinated movements by machines which are motorized by compressed air.

When the forming process concludes, these bottles (especially the ones determined for alcoholic spirits) go through a treatment method to improve chemical conflicts. As the bottles of glass cool, they will proceed to reduce in size and become hardened. If glass bottles are not cooled evenly, they will break easily. To evenly cool food thermos containers, they are fed into an annealing oven or lehr.

The glass bottles are now ready for the cold end process, or inspection route. Glass bottles are examined thoroughly for any number of shortcomings from cracks to foreign additions. Next comes the labeling process. Labels are placed using screen printing or in some cases, using vitreous enamel paint which is baked on the glass bottle. The original major soda company bottles used this method.

The glass bottles are now ready to be packaged and shipped, by methods of bulk pallets, boxed or packed in hand-sewn bags. Each package is given specific labels and warehoused. Glass bottles can be recycled and Governments of many countries impose a high price on cullet to ensure equal return rates. Mugs / tumblers can be reused, and practiced in many developing countries. is a large distribution company based in Miami, Florida. They are web-based and factory-direct which allows them to keep prices lower than the rest of the competition. They also have a huge selection of products from coffee mugs and travel mugs to wine glasses and promotional pens. For more information on wine glasses visit Discount Mugs.

Great Pollution Caused by Plastic Bottles

Le 14 March 2018, 10:41 dans Humeurs 0

In the late 1970s, kids stainless steel water bottle was introduced in the market and was widely accepted by many consumers. Then, in year 2000 bottled water companies bloomed and had caused a strain in the natural environment due to the production of 1.5 million tons of plastic bottle per year which causes pollution worldwide.

According to statistics, bottled water causes pollution because tons of crude oil is being used to produce bottled waters. An environmentalist once said that is takes 17 million of oil barrels to make 1.5 million plastic containers which is actually enough to fuel 1 million cars, also it would take 2.7 million tons of plastic are needed to make plastic containers each year. Though the governments have supported the recycling of this plastic bottle, data shows that from 53% recycling of bottled water in 1993 it decreases to 12% of the total plastic bottles in the year of 2003.

For the environmentalists' view, the continuous decrease of recycled plastic bottles were becoming very alarming and one solution that they cam up to solve this problem is the formation of a national law that would enable the government to come with a plan on how to give incentives for those who would help the government in recycling plastic ware especially plastic bottles.

Some experts say that it is much better to drink tap water than bottled water because of the following reasons:

? Cheaper cost per gallon of tap water compared to bottled water
? 90% of bottled water are not recycled
? 2.5 million tons of carbon dioxide is thought to be generated in the year 2006 for the production of plastic bottle.
? Phthalet contamination - commonly used in making plastic may contaminate the water inside the plastic container especially those old BPA free water bottles.
? Bisphenol A contamination - Bisphenol is a harmful chemical which is a common component of plastic bottled. It has a tendency to contaminate water once the plastic bottle is heated or if there is a crack in the bottle itself.

Statistics have shown that USA is the largest consumer of water in plastic bottle in the world. Some are not aware of the consequences of buying tritan water bottles while others are simply ignoring the harmful effects of such. Although the government have already assured the public that all water coming out of their faucet are all clean and drinkable still bottled water continues to increase its sale yearly and according to one data coming from government institution, Americans have already spent $11 billion of dollars on bottled H2O in the year of 2006 only and are expected to increase yearly. Furthermore, reports show that in that same year 1 out of 5 plastic containers have been recycled.

One company in the State of Colorado named "BIOTA" have invented a biodegradable plastic which is actually made of dow chemical and corn starch that is processed by seed company Cargill. Compared with the ordinary plastic bottle which takes 1,000 years to degrade, the plastic bottle made from BIOTA takes only 80 days. This invention might help us ease the strain in the environment and keep us away from the damaging effects of pollution.

Why is Bottled Drinking Water So Popular?

Le 19 January 2018, 08:27 dans Humeurs 0

Despite a dedicated campaign by many municipal water companies and associations to marginalize kids stainless steel water bottle in the eyes of the American consumer, exactly the opposite has happened - bottled water is more popular than ever and continues to grow in popularity.

Perhaps this is because the American consumer is truly an educated consumer and for years they have been misled about the purity of municipal tap water that is laced with contaminants and harmful chemicals and tainted with chlorine and other additives that impart nauseating odors and taste.

One of the most popular features of plastic bottles is that it does not require heavy doses of chlorine and so its taste is definitely more appealing than tap water, And, if one reads the purity reports issued by municipal water suppliers and required by the Environmental Protection Agency, it becomes evident that municipal water suppliers do not have the technology to purify large scale consumption of water.

One should read the reports carefully and note the warnings about cryptosporidium, rocket fuel, people with compromised immune systems or chronic illnesses and gasoline additives that remain in municipal water even after treatment and chlorination.

Bottled drinking water also contains no caffeine, no calories and no sugar and thereby competes with carbonated soft drinks that themselves are unhealthy in a world seeking higher health standards.

Water in bottles may seem like a relatively new idea--one born during the heightened awareness of fitness and potential water pollution during the last two or three decades but it traces its roots to the 19th century in America. The water is also be used as an ingredient in beverages, such as diluted juices or flavored BPA free water bottles.

Water that has been treated by distillation, reverse osmosis, or other suitable processes and that meets the definition of "purified water" is the best bottled water and studies show it.

Water cannot be called purified" unless it is 99.9% free of any and all contaminants - a test that all municipal water and most bottled waters fail to meet.

Bottled drinking water has a valid place in the marketplace, so unless one is willing to give up all bottled beverages it seems a little hypocritical to single out water. It is so ubiquitous that people can hardly ask for water anywhere without being handed a bottle.

Water in bottles is the fastest-growing segment of the beverage industry, and the product has now passed both coffee and milk to become the second-most-consumed beverage. Water in tritan water bottle that crosses state lines is considered a food product and is overseen by the Food and Drug Administration (FDA), which does mandate that it be bottled in sanitary conditions using food-grade equipment.
