In one example, a cap includes a body that has a plug defined by a recess extending downward from an upper surface of the body. The body also includes a skirt disposed circumferentially about the plug such that a gap is defined between an exterior surface of the plug and an inner surface of the skirt. Two or more tongues are connected to the skirt and extend radially inward toward the plug, each of the tongues configured to releasably engage respective corresponding structure of a container. A seal is provided that is disposed about an outer surface of the plug so as to be concentric with the plug, the seal including multiple radially extending circumferential fins.

The invention relates to a closure cap (2) with a closure cap axis (10), a cylindrical cap shell (3), a cover disk (5), and an engagement element (6) formed on the inside of the cap shell (3) and projecting towards the closure cap axis (10), wherein the engagement element (6) is designed as an internally threaded part or as a bayonet locking part, wherein the cover disk (5) has a breakthrough (4) in the region of its periphery, and wherein the engagement element (6) is arranged below the break-through (4) with respect to the breakthrough (4) in the direction of the closure cap axis (10).

A preform can be made from two different materials that do not bond together by a bi-injection process, using the same mold. First an outer preform can be fashioned first, then an inner preform molded through a center hole in the outer preform, and the preforms connected. Inner/outer preform materials can be different, e.g., PET/polyolefin or polyamide, or the same, e.g., PET/PET. To prevent mutual bonding during molding of the second, a non-stick coating can be sprayed on a surface portion of the first preform prior to molding, the second. Manufacturing order can be either outer/inner, or inner/outer, and the non-stick coating sprayed on the inside/outside of the perform first molded.

A transport container for at least one nutrient medium carrier, wherein the transport container comprises a base element and a cover element, the base element and the cover element are connectable to each other, the base element and the cover element are connected to each other in a closed state of the transport container and enclose an interior space of the transport container, and the at least one nutrient medium carrier can be arranged in the interior space. Furthermore, a method for automated microbial monitoring in a barrier system is provided.

A high quality child resistant container comprising a durable metallic reservoir and durable plastic metal cap. The child resistant container comprises a durable and rugged reservoir and similarly durable locking cap. The cap is secured to the reservoir by a threaded, or bayonet-style connection. Once installed on the reservoir, the cap is prevented from being easily removed by a child, due to child resistant features integrated in the design of the cap and reservoir. Also, a method of reducing friction between the sealing surfaces of a sealed container. Specifically between the reservoir, cap and seal of a container, which allows easier closing of containers which require a simultaneous compression and twist motion to close.

A container and closure includes a closure secured to the container through projections comprising a series of horizontal, circumferentially spaced apart elements arranged so that the elements on the closure can pass though the spaces between the elements on the container and locate beneath them to secure the closure to the container. The elements of the projection on the container are separated from each other in the circumferential direction and do not overlap with each other in the vertical direction and the elements of the projection on the closure are separated from each other in the circumferential direction and do not overlap with each other in the vertical direction. The closure carries a sealing member for providing a seal with either an internal or external sealing surface of the container. The seal is driven down from a lead-in surface to engage the sealing surface as the closure is rotated.

A preform made from two different materials that do not bond together by a bi-injection process, using the same mold, is presented. An outer layer of the preform can be first made, then an inner layer molded through a center hole in a bottom of the outer layer, and the two layers connected. Inner/outer preform materials can be different, such as PET/polyolefin or polyamide, or the same, such as PET/PET. To prevent mutual bonding during molding of the second layer, a non-stick coating may be sprayed onto a surface portion of the first layer prior to molding the second. In embodiments, manufacturing order can be either outer/inner, or inner/outer, and the non-stick coating sprayed on the inside/outside of the layer first molded.
