A clothes hanger, coat hanger, or coathanger, is a device in the shape of:
Human shoulders designed to facilitate the hanging of a coat, jacket, sweater, shirt,
blouse or dress in a manner that prevents wrinkles, with a lower bar for the hanging of
trousers or skirts.
Clamp for the hanging of trousers, skirts, or kilts. Both types can be combined in a
single hanger.
There are three basic types of clothes hangers. The first is the wire hanger, which has a
simple loop of wire, most often steel, in a flattened triangle shape that continues into a
hook at the top. The second is the wooden hanger, which consists of a flat piece of
wood cut into a boomerang-like shape with the edges sanded down to prevent damage
to the clothing, and a hook, usually of metal, protruding from the point.
A can opener (in North American English and Australian English) or tin opener (in
British and Commonwealth English) is a device used to open tin cans (metal cans).
Although preservation of food using tin cans had been practiced since at least 1772 in
the Netherlands, the first can openers were not patented until 1855 in England and
1858 in the United States.
These early openers were basically variations of a knife, though the 1855 design
continues to be produced. The first can opener consisting of the now familiar sharp
rotating cutting wheel was invented in 1870 but was considered too difficult to operate
for the ordinary consumer. A breakthrough design came in 1925 when a second,
serrated wheel was added to hold the cutting wheel on the ring of the can. This easy to
use design has become one of the most popular can opener models.
Mail order is the buying of goods or services by mail delivery. The buyer places an order
for the desired products with the merchant through some remote method such as
through a telephone call or web site. Then, the products are delivered to the customer.
Earmuffs are objects designed to cover a person’s ears for hearing protection or for
warmth. They consist of a thermoplastic or metal head-band, that fits over the top or
back of the head, and a cushion or cup at each end, to cover the external ears.
