Screwcap
A screw cap or closure is a common type of closure for bottles, jars, and tubes. Usage A screw closure is a mechanical device which is screwed on and off of a "finish" on a container. Either continuous threads or lugs are used. It must be engineered to be cost-effective, to provide an effective seal (and barrier), to be compatible with the contents, to be easily opened by the consumer, often to be reclosable, and to comply with product, package, and environmental laws and regulations. Some closures need to be tamper resistant and have child-resistant packaging features. A tamper-evident band is a common tamper warning for screw caps of bottles, for example. Wine industry Screw caps' use as an alternative to cork for sealing wine bottles is gaining increasing support. A screw cap is a metal cap that screws onto threads on the neck of a bottle, generally with a metal skirt down the neck to resemble the traditional wine capsule ("foil"). A layer of plastic (often PVDC), cork, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screw Cap (wine)
A screw cap is a metal, normally aluminium, cap that screws onto threads on the neck of a wine bottle, generally with a metal skirt down the neck to resemble the traditional wine capsule ("foil"). A layer of plastic (often PVDC), cork, rubber, or other soft material is used as wad to make a seal with the mouth of the bottle. Its use as an alternative to cork for sealing wine bottles is gaining increasing support. In markets such as Australia and New Zealand screw caps on bottles have overtaken cork to become the most common means of sealing bottles. Benefits and concerns Compared to cork, screw caps reduce the wine faults of oxidation and of cork taint, although it is possible to find TCA contamination in a screw cap bottle. Screw caps are generally perceived as easier to open and they are much easier to reseal. Screw caps have a much lower failure rate than cork, and in theory will allow a wine to reach the customer in perfect condition, with a minimum of bottle variation. Howe ...

Alternative Wine Closure
Alternative wine closures are substitute closures used in the wine industry for sealing wine bottles in place of traditional cork closures. The emergence of these alternatives has grown in response to quality control efforts by winemakers to protect against "cork taint" caused by the presence of the chemical trichloroanisole (TCA). The closures debate, chiefly between supporters of screw caps and natural corks, has increased the awareness of post-bottling wine chemistry, and the concept of winemaking has grown to continue after the bottling process, because closures with different oxygen transmission rates may lead to wines that taste different when they reach consumers. The cork-industry group APCOR cites a study showing a 0.7–1.2% taint rate. In a 2005 study of 2800 bottles tasted at the ''Wine Spectator'' blind-tasting facilities in Napa, California, 7% of the bottles were found to be tainted.Laube, James, ''Wine Spectator'' (March 31, 2006)Changing With the Times Syn ...

Closure (container)
A closure is a device used to close or seal a container such as a bottle, jug, jar, tube, or can. A closure may be a cap, cover, lid, plug, liner, or the like. The part of the container to which the closure is applied is called the finish. Other types of containers such as boxes and drums may also have closures but are not discussed in this article. Many containers and packages require a means of closing, which can be a separate device or seal or sometimes an integral latch or lock. Purpose of closures The closure is often the most critical part of a package, and must fulfill all of the basic functions of packaging in addition to being easy to open and (if applicable) reclose. Depending on the contents and container, closures have several functions: * Keep the container closed and the contents contained for the specified shelf life until time of opening * Provide a barrier to dirt, oxygen, moisture, etc. Control of permeation is critical to many types of products: foods, ...

PVDC
Polyvinylidene chloride, or polyvinylidene dichloride (PVDC), is a homopolymer of vinylidene chloride. History Ralph Wiley accidentally discovered polyvinylidene chloride polymer in 1933. He, then, was a college student who worked part-time at Dow Chemical lab as a dishwasher. While cleaning laboratory glassware, he came across a vial he could not scrub clean. Dow researchers made this material into a greasy, dark green film, first called "Eonite" and then " Saran". Ralph Wiley went on to become one of Dow Chemical's research scientists and invent and develop many plastics, chemicals and production machines. The military sprayed Saran on fighter planes to guard against salty sea spray, and carmakers used it for upholstery. Dow later devised a formulation of polyvinylidene chloride free of unpleasant odour and green colour. The most well known use of polyvinylidene chloride came in 1953, when Saran Wrap, a plastic food wrap, was introduced. In 2004, however, the formula was ...

ASTM
ASTM International, formerly known as American Society for Testing and Materials, is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. Some 12,575 ASTM voluntary consensus standards operate globally. The organization's headquarters is in West Conshohocken, Pennsylvania, about northwest of Philadelphia. It is founded in 1902 as the American Section of the International Association for Testing Materials (see also International Organization for Standardization). History A group of scientists and engineers, led by Charles Dudley, formed ASTM in 1898 to address the frequent rail breaks affecting the fast-growing railroad industry. The group developed a standard for the steel used to fabricate rails. Originally called the "American Society for Testing Materials" in 1902, it became the "American Society for Testing And Materials" in 1961. In 2001, ASTM offic ...

Permeation
In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (a fluid such as a liquid, gas, or vapor) through a solid. It is directly related to the concentration gradient of the permeate, a material's intrinsic permeability, and the materials' mass diffusivity. Permeation is modeled by equations such as Fick's laws of diffusion, and can be measured using tools such as a minipermeameter. Description The process of permeation involves the diffusion of molecules, called the permeant, through a membrane or interface. Permeation works through diffusion; the permeant will move from high concentration to low concentration across the interface. A material can be semipermeable, with the presence of a semipermeable membrane. Only molecules or ions with certain properties will be able to diffuse across such a membrane. This is a very important mechanism in biology where fluids inside a blood vessel need to be regulated and controlled. Permeation can o ...

Packaging
Packaging is the science, art and technology of enclosing or protecting products for distribution, storage, sale, and use. Packaging also refers to the process of designing, evaluating, and producing packages. Packaging can be described as a coordinated system of preparing goods for transport, warehousing, logistics, sale, and end use. Packaging contains, protects, preserves, transports, informs, and sells. In many countries it is fully integrated into government, business, institutional, industrial, and personal use. Package labeling (American English) or labelling (British English) is any written, electronic, or graphic communication on the package or on a separate but associated label. History of packaging Ancient era The first packages used the natural materials available at the time: baskets of reeds, wineskins (bota bags), wooden boxes, pottery vases, ceramic amphorae, wooden barrels, woven bags, etc. Processed materials were used to form packages as they were develop ...

Flip-top
A flip-top, swing-top, lightning toggle, or Quillfeldt stopper (after the inventor, Charles de Quillfeldt) is a type of closure frequently used for bottles containing carbonated beverages, such as beer or mineral water. The mouth of the bottle is sealed by a stopper, usually made of porcelain or plastic, fitted with a rubber gasket and held in place by a set of wires. The bottle can be opened and resealed repeatedly and without the use of a bottle opener, with the wires acting in the same way as a latch clamp. The flip-top was the dominant method of sealing beer and mineral water bottles prior to the invention of the crown cork. This is sometimes called a bail closure. History Prior to the creation of the flip-top bottle, bottles were often made from blown glass and sealed with a cork, which was difficult to open by hand and often unreliable, particularly for carbonated beverages such as mineral water or beer. A precursor to the flip-top, the "bail" or "Kilner" closure w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Child-resistant Packaging
Child-resistant packaging or CR packaging is special packaging used to reduce the risk of children ingesting hazardous materials. This is often accomplished by the use of a special safety cap. It is required by regulation for prescription drugs, over-the-counter medications, Nicotine Containing Electronic Cigarette devices or Refill containers that can contain Nicotine EUTPD 36.7 pesticides, and household chemicals. In some jurisdictions, ''unit packaging'' such as blister packs is also regulated for child safety. The U.S. Consumer Product Safety Commission has stated in a press release that "There is no such thing as child-proof packaging. So you shouldn't think of packaging as your primary line of defense. Rather, you should think of packaging, even child-resistant packaging, as your last line of defense." Background The child-resistant locking closure for containers was invented in 1967 by Dr. Henri Breault. A history of accidents involving children opening household packagi ...
