Abstract: A tubular container for adhesive material includes a substantially tubular body and a relatively rigid spout. An insert disposed in the spout hinders the intrusion of air through the spout. A plate is positioned so that the edge of the plate abuts the shoulder of the tubular body. The plate is supported by the insert at locations spaced from the edge of the plate. The exertion of pressure on the center of the plate causes the edge of the plate to be separated from the shoulder of the tubular body, thereby defining a passage for adhesive material.

Abstract: The invention relates to a toy building block set comprising several plane blocks of various kinds. The building block set includes a cuboid panel block (1) having height h, width b and thickness d, an elongated beam block (2) with a square cross-section and length h and thickness d, and a trapezoid block (3) with thickness d, width of the tip nearly d, width of the base nearly b and length of a sloping side nearly h, the proportion of d:b:h being 1:3:4. The blocks, which are preferably made of synthetic material or wood, may be connected with each other by a peg and hole connection (4,5). The blocks may be used to construct very true-to-life and esthetically appealing structures.
