A container having enhanced wall integrity is provided that includes a sidewall having a polygonal cross-sectional shape and an alignment structure formed therein. The alignment structure is adapted for orienting the container with respect to a second container such that the panel sections of the containers become parallel with one another and the containers may be fully nested one within the other. The alignment structure can be recessed into the sidewall to form peaks and valleys along an inner surface of the container. Alternatively, the alignment structure can protrude from the sidewall to form peaks and valleys along an inner surface of the container. The peaks include first and second faces sloping in opposite directions designed to direct corners of the first container's sidewall toward the valleys of the second container in order to orient the containers as they are stacked.

Disclosed is a test barrel, to prevent a test liquid in the barrel from sputtering into a connection gap due to shaking of the barrel to hence cause contamination, improve the measurement accuracy in case of multiple tests, and meanwhile improve the operability of screwing on and screwing off the entire device during use of the device. The above technical objective of this utility model is implemented by employing the following technical solution: a test barrel, comprising barrel lid and a barrel body; wherein the threaded rings are arranged on an inner wall of a side face of the barrel lid and an outer wall of an opening of the barrel body, a rotary force applying portion is arranged on an outer wall of the side face of the barrel lid, and during engagement, a liquid blocking washer is arranged between the barrel lid and the barrel body, wherein a radial width of the liquid blocking washer is greater than a thickness of the opening of the barrel body.

A resin composition comprises: a modified EVOH (A) that is represented by a following formula (I), has contents (mol %) of a, b, and c based on the total monomer units satisfying following formulae (1) through (3), and has a degree of saponification (DS) defined by a following formula (4) of 90 mol % or more; and inorganic oxide particles (B), wherein a content of the inorganic oxide particles (B) is from 5 to 5000 ppm. Such a resin composition is improved in adhesion to a resin other than EVOH, secondary processability, and flexibility without decreasing the performances originally possessed by EVOH, such as gas barrier properties, transparency, flavor retention, solvent resistance, and oil resistance. Accordingly, the resin is preferably used as a molded article, a film, a sheet, a heat shrinkable film, a thermoformed article, a multilayer structure, a coinjection stretch blow molded container, a fuel container, and the like. ##STR00001##
