A stool container is provided with a lid body () having a lid part () for sealing a container and a stool collection rod () for collecting stool, a cylindrical container body () that has a liquid reservoir () formed at the distal end thereof via a filter holding part () and has an open proximal end, and an inner plugthat is inserted from the proximal end of the container body () in to the container body (). The distal end of the inner plug () has a bottom surface () that is orthogonal to the longitudinal direction and, in the center of the bottom surface (), a scraping part () through which the stool collection rod () can be inserted. A stool collection rod guide part is formed that comprises a plurality of sloping ribs () disposed radially around the scraping part ().

Stool collection container

A compound container has a container main body forming a first accommodation chamber, an auxiliary container forming a second accommodation chamber, a mounting part on which the auxiliary container is mounted in the container main body, a cutting part which cuts a second accommodation chamber partition wall which partitions a part of the second accommodation chamber formed in the auxiliary container, a contents outlet port in the container main body, and an opening pouring element mounted on the contents outlet port and having another cutting part which cuts a first accommodation chamber partition wall which partitions a part of the first accommodation chamber formed in the container main body.

Compound container and pouring-out method

Provided is a twist-cut unsealing mechanism in which an operator can surely sense the fact that twist-cutting of a seal member has completed in assembling of spout and cap of such a type that a container is unsealed by twisting and cutting a seal member for the liquid passage of a spout by means of a cap. A twist-cut unsealing mechanism includes both-side protrusions arranged along a virtual circle rounding around the center line of rotation and an abutment protrusion movable relatively to the both-side protrusions along the virtual circle, and is configured so that one of the both-side protrusion and the abutment protrusion for indicating completion of twist-cut is fixed to a spout () and the other protrusion is fixed to a cap (), the both-side protrusion has a sliding surface of gentle slope and a stopper surface of steep slope wherein projection heights of both surfaces are substantially same in the radial direction and both surface are adjacent to each other along a circle, the abutment protrusion can abut against the sliding surface and the stopper surface, and at a position where the abutment protrusion passed the sliding surface in the rotational direction, the relative rotation positions of the spout () and the cap () is set above the twist-cut completion position of a seal member () and within detachment allowance positional range where the detachment of the cap () is permitted.

Twist-cut unsealing mechanism for container

A pouring member includes an unsealing cap and at least two rotation prevention sections extending vertically and downwardly from an end surface of an open end side of the unsealing cap and is arranged such that the at least two rotation prevention sections are apart from one another by an angle which is larger than a rotation angle required for twisting off the sealing part, and symmetrically with respect to the central axis of the unsealing cap. A recess is formed such that the recess opens to a front end side of the rotation prevention section, and an engagement projection engages the recess in a direction substantially parallel with a direction in which the rotation prevention sections are extended vertically and downwardly, and is formed at a specific position of the flange part of the pouring member.
