The present invention relates to compositions (compounds) which can be used as seal material in vessel caps under sterilization conditions. More specifically, the invention relates to such compositions that are suitable for vessel caps or vacuum caps that can be unscrewed, such as cam screw caps and in particular Press-on/Twist-off caps, and that demonstrate a reduced migration of undesirable substances.

A crown-type metal cap for sealing the mouth of a preferably aluminum metal bottle, the cap being formed by a laminar part of circular plan form, including an inner face and an outer face and provided peripherally with a closure skirt and, on the inner face, with a closure gasket including a peripheral lip. The cross-section of the peripheral lip is formed by a convex arc having at least one radius of curvature, adjacent to the closure skirt, the lip also including a side opposite the closing skirt, which can be a straight side or a curved side having a radius of curvature greater than that of the convex arc.

A container for collecting a biological specimen is provided that includes a peripheral wall extending from a base. The container further includes a longitudinal tower disposed within the container. The tower forms a partition within the container to form at least a first chamber and a second chamber therein, wherein the first and second chambers are in fluid communication with one another. In addition, the container includes an insert disposed within the container opposite the base, the insert comprising at least a first opening and a second opening. The second opening provides access to the second chamber and is further configured to engage a specimen collecting device to leave a portion of the specimen collecting device within the second chamber. The first opening provides access to the first chamber and is further configured to receive a syringe therein for accessing the biological specimen. Associated systems and methods are also provided.

A bottle includes a bottom wall portion of a bottom portion, grounding portion at an outer circumferential edge, rising circumferential wall portion continuous with grounding portion from the bottle radial inner side, and movable wall portion protrudes from the rising circumferential wall portion upper end. The movable wall portion movable upward around a connected portion to the rising circumferential wall portion. Plurality of ribs are radially disposed around bottle axis on the movable wall portion, and ribs include main recess that is recessed upward, and connection recess. Plurality of main recesses arranged at predetermined intervals in the bottle radial direction, and connection recess connects main recesses, adjacent to each other in the bottle radial direction, in the bottle radial direction together. A depth ratio D2/D1 that is the ratio of a depth (D2) of the connection recess to a depth (D1) of each main recess <2/9 and 1.

Polyethylene formulations and articles produced therefrom, comprise a multimodal high density polyethylene (HDPE) composition, and 0.1 ppm to 300 ppm of a nucleating agent, wherein the multimodal HDPE composition comprises a density of 0.940 g/cm.sup.3 to 0.970 g/cm.sup.3 when measured according to ASTM D792, and a melt index (I2) of 0.1 g/10 min. to 10.0 g/10 min. when measured according to ASTM D1238 at 190 C. and a 2.16 kg load, and wherein the multimodal HDPE composition comprises an infrared cumulative detector fraction (CDF.sub.IR) of greater than 0.27 and an infrared cumulative detector fraction to light scattering cumulative detector fraction ratio (CDF.sub.IR/CDF.sub.LS) from 0.7 to 2.0.

A cap assembly for a container has an inner sleeve that is secured to the neck of the container and an outer cap that is adjustably secured to the inner sleeve. The outer cap can be adjusted downwardly relative to the inner sleeve so that a gap between the bottom of the outer cap and a top of the container can be minimized or eliminated.

A container adapter includes a first chamber. The first chamber is adapted to attach to a container. The container further includes a second chamber. The second chamber includes a sealing surface and a resealable interface disposed between the first chamber and the second chamber. The second chamber is exposed to an ambient environment.

A crown cap and closing device. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. 1.72(b). As stated in 37 C.F.R. 1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading Abstract of the Disclosure. The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

A self-priming-pump-equipped packaging bottle includes a tubular bottle body containing therein an upper seal assembly, a lower seal assembly, and piston from top to bottom. The upper and lower seal assemblies and the tubular bottle body form a closed material-feeding chamber. The lower seal assembly, the piston, and the tubular bottle body form a closed material-storing chamber. The lower seal assembly primarily has a seal seat with a through hole and an elastic sealing gasket covering the through hole from above. The upper seal assembly has an umbrella-shaped member, a hollow material-feeding column, a support post, and an end sealing cap. The end sealing cap is fixed in the umbrella-shaped member through the support post. The hollow material-feeding column's bottom surface, the support post, and the end sealing cap form a material outlet. The umbrella-shaped member lower end is in interference fit with the seal seat.
