It is a photograph showing a state of storing one foldable cup set in a compression packaging pack, and FIGS. 14A to 14B are photographs showing a state of folding a cup body provided in a foldable cup set with a foldable straw according to the present invention in half.

As shown in these drawings, it is preferable that the cup body 100 is provided in the folding cup set having a folding straw according to the present invention.

The cup body 100 is preferably made of a material capable of elastic deformation. That is, the cup body 100 is preferably made of a silicone or rubber material. In addition, the cup body 100 may be made of a material such as fabric, leather, or synthetic resin rather than a paper material.

Therefore, the cup body 100 can be used semi-permanently by preventing an increase in waste and waste disposal costs due to disposable paper cups that are used once and discarded, thereby reducing the generation and disposal costs of waste and waste. There is this.

Such a cup body 100 is preferably made of a bottom surface 120 and a rim surface 110 so as to have an inner receiving portion in which only the upper portion is opened.

In this case, the cup body 100 is preferably formed to have a tapered edge surface 110 that narrows in width from the top to the bottom, and the bottom surface 120 is in any one of a circular shape, a square shape, and a hexagonal shape. In this case, the edge surface 110 is formed to correspond thereto.

In addition, the cup body 100 may include a support layer 102 formed to form a cup shape, and a coating layer 104 coated on the inner side of the support layer 102.

At this time, the coating layer 104 is preferably coated with a metal containing silver nanoparticles, which emits far-infrared rays and has antimicrobial activity, in a ratio of 0.05% by weight or more to 10% by weight or less of the support layer 102.

Usually, silver has a specific gravity of 10 to 12, Mohs hardness of 2.5 to 3, and a melting point of 960. The efficacy of silver is that when worn on the body from ancient times, the gloss or color changes depending on the condition of the body. It was also used as a tool to identify it.

In addition, Donguibogam is said to be effective in the prevention and treatment of mental disorders and gynecological diseases such as epilepsy and game, and it served as a herbal medicine taken by powdering silver. It is recorded in the Bonchogangmok that the people are elongated by being expelled and lightening the body.

In addition, when the Black Death was widespread in the Middle Ages, the Black Death did not occur to the nobles and royals who had a lot of silver dishes and silver utensils, which was said to be relatively safe from infectious diseases because negative ions generated from silver were released enough to sterilize the Black Death bacteria. It is said that silver products were used habitually in places where the royal family and state guests were enshrined.

The atomic weight of silver is 107.87 amu, and that silver has sterilizing power has been known for a long time, regardless of the age of the east and the west.

The metal coated with such silver nanotechnology has a strong antibacterial and sterilizing function, and an excellent electrical conductivity mechanism to block electromagnetic waves, so it has been found that bacteria do not have resistance in containers made of these metals. It was found to sterilize all single cell pathogens in a short time. The main antibacterial mechanism of silver nano is to melt the cell membrane of harmful bacteria and act with enzymes in the cell to block the metabolic function of nutrients, that is, the inflow and discharge of nutrients, and prevent the respiratory function and production of harmful bacteria, destroying the growth arrest and regeneration ability of harmful bacteria. To kill harmful bacteria.

Unlike general chemical antibacterial agents or chlorine-based disinfectants, silver nano is pure silver ultrafine particles, so it has excellent antibacterial/sterilization power even at high temperatures, and is non-toxic and non-irritating to the human body. Bacteria or E. coli virus fungi are in contact with silver nano materials for more than 5 minutes. It has been reported that it is impossible to live.

The silver nano extraction method involves adding silver (Ag 99.9%) to distilled water and generating a low current at a low temperature to electrolyze a compound containing silver, and then electrophoresis using the + and-poles of each molecule. Ag 99.9%) can be collected, and in addition, it can be prepared by physical methods such as liquid reduction method and grinding. In order to obtain stable silver nanomaterials, the above electrolysis method is widely used.

As an embodiment for forming a cup body of the present invention, after making a pure silver ionized water solution by electrolysis from a silver ion generator, the cup body is precipitated for a certain period of time, and then, after a drying process, silver nanomaterials are added to the cup body. The method of being coated was used.

As another method, in order to emit a lot of negative ions and far-infrared rays, silver with antibacterial activity was applied to silica to form silica silver nano, and then coated on the inside of the cup body.

As a result of several experiments with silver nanomaterials coated in this way, if at least 0.05% by weight of the support layer was formed, moisture did not penetrate into the support layer even if water was stored for 3 to 4, and the shape did not change and reuse was not possible. It became possible.

In addition, it will be said that the more silver nanomaterials are coated, the better the effect, but in a state that exceeds 10% by weight of the support layer or 10% by weight of the support layer, moisture did not penetrate at all, and the shape did not change even if stored for 3-4 days . That is, in the state in which the silver content exceeded 10% by weight of the support layer, even if more coating was applied, the increased effect did not appear any more.

Therefore, in consideration of the object and economic aspect of the invention, it was tested that the silver nanomaterial is preferably coated in an amount of 0.05% by weight or more to 10% by weight or less of the support layer.

When the silver coating layer is formed in this way, it is possible to maintain a more beneficial state for the human body by providing far-infrared rays and antibacterial activity by the silver coating layer.

The cup body 100 of the present invention is made of a material that can be elastically deformed, and is compressed in both directions so that it can be restored to its original state, so that the bottom surface 120 and the rim surface 110 can be folded flatly ( 130) is preferably formed.

The folding groove 130 is preferably made of first to sixth folding grooves 131 to 136 formed to be concave in the inner wall of the bottom surface 120 and the rim surface 110 of the cup body 100.

Do.

In addition, the fourth folding groove 134 is formed so that the bottom surface 120 is folded flat together when the edge surface 110 is folded flat by the first to third folding line grooves 131 to 133. It is preferable that it is formed in a transverse direction at the center of the bottom surface 120 so as to be connected at the lower end of the first folding groove 131, and the fifth to sixth folding grooves 135 to 136 are the fourth folding grooves 134 ) Formed in a diagonal direction corresponding to each other so that the bottom surface 120 can be folded flat by being connected at the bottom of the second to third folding grooves 132 to 133 on both sides of the bottom surface 120 It is desirable.

In this way, by forming the first to sixth folding grooves 131 to 136 in the cup body 100, the cup body 100 can be folded flat to facilitate storage and portability. At this time, it can be stored and carried while maintaining the folded state by using the compression packaging pack 400 to be described later.

In addition, the thickness (t) of the edge surface 110 and the bottom surface 120 in which the folding groove portion 130 is formed, that is, formed by the first to sixth folding grooves 131 to 136, is It is preferable to be formed to have a thickness of less than half of the total thickness (T) of (110) and the bottom surface (120).

In addition, the first to sixth folding grooves 131 to 136 constituting the folding groove 130 are preferably formed as concave grooves having a semicircular cross section.
