Closure (container)
A closure is a device used to close or seal a container such as a bottle, Jug (container), jug, jar, Tube (container), tube, or can (other)#Container, can. A closure may be a cap, cover, Lid (container), 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 drum (container), 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 food packaging#Functions, 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 open ...

Bottle Can
A bottle is a narrow-necked container made of an impermeable material (such as glass, plastic or aluminium) in various shapes and sizes that stores and transports liquids. Its mouth, at the bottling line, can be sealed with an internal Stopper (plug), stopper, an external bottle cap, a Closure (container), closure, or induction sealing. Etymology First attested in 14th century. From the English word ''bottle'' derives from an Old French word ''boteille'', from vulgar Latin ''butticula'', from late Latin ''buttis'' ("cask"), a Latinisation (literature), latinisation of the Greek language, Greek βοῦττις (''bouttis'') ("vessel"). Types Glass Wine The glass bottle represented an important development in the history of wine, because, when combined with a high-quality stopper (plug), stopper such as a cork (material), cork, it allowed long-term aging of wine. Glass has all the qualities required for long-term storage. It eventually gave rise to "château bottling", the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the Hevea brasiliensis, Pará rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". Manufacturers refine this latex into the rubber that is ready for commercial processing. Natural rubber is used extensively in many applications and products, either alone or in combination with other materials. In most of its useful forms, it has a large stretch ratio and high resilience and also is buoyant and water-proof. Industrial demand for rubber-like materials began to out ...

Tamper-evident Band
A tamper-evident band or security ring serves as a tamper resistant or tamper evident function to a screw cap, lid, or closure. The term ''tamper-proof'' is sometimes used but is considered a misnomer given that pilfering is still technically possible. A security band can be integrated with the cap or can be a separate package component. It is a plastic or metal structure around the circumference (usually) of the closure that is often found attached below a closure in bottles, jars, and tubs. Several variations have been developed for caps, lids, and closures. The use of custom printing and security printing is available. Perforations or other areas of weakness are often used to initiate and control a tear. Sometimes engineered frangibility is used for break-away functions. While tamper-evident bands are not considered a challenge for recycling, it is important that the band stays attached to the cap in case of refillable bottles, because it is hard to remove the r ...

Interference Fit
An interference fit, also known as a pressed fit or friction fit, is a form of fastening between two tightfitting mating parts that produces a joint which is held together by friction after the parts are pushed together. Depending on the amount of interference, parts may be joined using a tap from a hammer or forced together using a hydraulic press. Critical components that must not sustain damage during joining may also be cooled significantly below room temperature to shrink one of the components before fitting. This method allows the components to be joined without force and produces a shrink fit interference when the component returns to normal temperature. Interference fits are commonly used with aircraft fasteners to improve the fatigue life of a joint. These fits, though applicable to shaft and hole assembly, are more often used for bearing-housing or bearing-shaft assembly. This is referred to as a 'press-in' mounting. Tightness of fit The tightness of fit is contr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Glass Joints
Ground glass joints are used in laboratories to quickly and easily fit leak-tight apparatus together from interchangeable commonly available parts. For example, a round bottom flask, Liebig condenser, and oil bubbler with ground glass joints may be rapidly fitted together to reflux a reaction mixture. This is a large improvement compared with older methods of custom-made glassware, which was time-consuming and expensive, or the use of less chemical resistant and heat resistant corks or rubber bungs and glass tubes as joints, which took time to prepare as well. One of the glassware items to be joined would have an ''inner'' (or male) ''joint'' with the ground glass surface facing outward and the other would have an ''outer'' (or female) ''joint'' of a correspondingly fitting taper with the ground glass surface facing inward. To connect the hollow inner spaces of the glassware components, ground glass joints are hollow on the inside and open at the ends, except for stoppers. H ...

Laboratory Glassware
Laboratory glassware is a variety of equipment used in science, scientific work, traditionally made of glass. Glass may be blown, bent, cut, molded, or formed into many sizes and shapes. It is commonly used in chemistry, biology, and analytical laboratory, laboratories. Many laboratories have training programs to demonstrate how glassware is used and to alert first–time users to the Laboratory safety#Safety hazards, safety hazards involved with using glassware. History Ancient era The history of glassware dates back to the Phoenicians who fused obsidian together in campfires, making the first glassware. Glassware evolved as other ancient civilizations including the Syrians, Egyptians, and Romans refined the art of glassmaking. Mary the Jewess, an alchemist in Alexandria during the 1st century AD, is credited for the creation of some of the first glassware for chemical such as the ''kerotakis'' which was used for the collection of fumes from a heated material.

Bottle Caps
A bottle is a narrow-necked container made of an impermeable material (such as glass, plastic or aluminium) in various shapes and sizes that stores and transports liquids. Its mouth, at the bottling line, can be sealed with an internal stopper, an external bottle cap, a closure, or induction sealing. Etymology First attested in 14th century. From the English word ''bottle'' derives from an Old French word ''boteille'', from vulgar Latin">-4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... word ''boteille'', from vulgar Latin ''butticula'', from late Latin ''buttis'' ("cask"), a Latinisation (literature), latinisation of the Greek language, Greek βοῦττις (''bouttis'') ("vessel").

Mason Jar
A Mason jar, also known as a canning jar, preserves jar or fruit jar, is a glass jar used in home canning to food preservation, preserve food. It was named after American tinsmith John Landis Mason, who patented it in 1858. The jar's mouth has a screw thread on its outer perimeter to accept a metal ring or "band". The band, when screwed down, presses a separate Stamping (metalworking), stamped steel disc-shaped lid (container), lid against the jar's rim. After Mason's patent expired, numerous other companies began manufacturing similar jars. Over the years, the Brand, brand name ''Mason'' became the Generic trademark, genericized trademark for that style of glass home canning jar, and the word "Mason" can be seen on many Ball Corporation, Ball and Kerr brand jars. The style of jar is occasionally referred to by common brand names such as Ball jar (in the eastern US) or Kerr jar (in the western US) even if the individual jar is not that brand. In early 20th-century United States, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polytetrafluoroethylene
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. The commonly known brand name of PTFE-based composition is Teflon by Chemours, a corporate spin-off, spin-off from DuPont (1802–2017), DuPont, which originally invented the compound in 1938. Polytetrafluoroethylene is a fluorocarbon solid, as it is a high-molecular-weight polymer consisting wholly of carbon and fluorine. PTFE is hydrophobic: neither water nor water-containing substances Wetting, wet PTFE, as fluorocarbons exhibit only small London dispersion forces due to the low polarizability, electric polarizability of fluorine. PTFE has one of the lowest Friction#Coefficient of friction, coefficients of friction of any solid. Polytetrafluoroethylene is used as a non-stick coating for Cookware and bakeware, pans and other Cookware and bakeware, cookware.
