The domestic beverage market, ranging from carbonated beverages to fruit juices to tea beverages, plus purified water for dairy products, can be described as a wide variety of products. The rich market profits of the beverage market have attracted more and more capital into this area.
The fierce market competition makes the product's innovation rate continue to accelerate. Many companies have made new products available in the market in a novel way. At the same time as the product line is becoming more and more abundant, they have done a lot to design and use beverage bottles. Bottles of beverage bottles have become increasingly diverse. From gardens to squares to shapes, a wide variety of beverage bottles have emerged. However, we have found that the diversity of beverage bottles is satisfying the eyeballs, but it is less and less satisfactory in terms of convenience and feel. We all know that Coca-Cola's S-Sex Beverage Bottle has played a significant role in its development. This is inseparable from the comfortable and good feel of the bottle shape. The beautiful shape may attract consumers for the first time, but it will not be recognized after use, or will be discarded by consumers. Drink bottles with square or a variety of special-shaped design, should be more careful.
A blackboard (also known as a Chalkboard) is a reusable writing surface on which text or drawings are made with sticks of calcium sulphate or calcium carbonate, known, when used for this purpose, as chalk. Blackboards were originally made of smooth, thin sheets of black or dark grey slate stone.
A blackboard can simply be a board painted with a dark matte paint (usually black, occasionally dark green).Matte black plastic sign material (known as closed-cell PVC foamboard) is also used to create custom chalkboard art.Blackboards on an A-frame are used by restaurants and bars to advertise daily specials.
A more modern variation consists of a coiled sheet of plastic drawn across two parallel rollers, which can be scrolled to create additional writing space while saving what has been written. The highest grade blackboards are made of a rougher version porcelain enamelled steel (black, green, blue or sometimes other colours). Porcelain is very hard wearing, and blackboards made of porcelain usually last 10–20 years in intensive use.
Lecture theatres may contain a number of blackboards in a grid arrangement.The lecturer then moves boards into reach for writing and then moves them out of reach, allowing a large amount of material to be shown simultaneously.
The chalk marks can be easily wiped off with a damp cloth, a sponge or a special blackboard eraser usually consisting of a block of wood covered by a felt pad. However, chalk marks made on some types of wet blackboard can be difficult to remove. Blackboard manufacturers often advise that a new or newly resurfaced blackboard be completely covered using the side of a stick of chalk and then that chalk brushed off as normal to prepare it for use.
