Abstract: A device for connecting parts of a crate includes a female sheet including a slot and a peripheral surface; and a male sheet including a tab and a peripheral surface, the male sheet being coupled to the female sheet by the tab. The tab includes a stop element in an upper part of the male sheet closest to the peripheral surface of the female sheet, an upper surface of the tab extending upward, and a front surface of the tab extending downward and being completed with a lower surface connected to an inclined guiding surface.

Abstract: A machine for assembling boxes comprising five independent parts including two head walls, two side walls and a base with peripheral flanges that engage with grooves in a lower portion of the side walls and the head walls. Ends of the head walls have end tongues that are inserted into notches adjacent to ends of the side walls. The machine includes a central assembly station comprising a base ring inside which a stationary forming die is disposed. A base of a box to be formed is positioned on a lower face of the stationary forming die such that while the base of the box is held in position, horizontal push devices are activated which move the head walls and the side walls towards the base of the box which is locked in position against the lower face of the stationary forming die.

Abstract: The invention relates to a stackable container that includes a lower part, base or bottom (1), two long lateral walls or side panels (2) and two short lateral walls or front panels (3) that include a flat element that can consist of two end base planks (10), of two pairs of cornered base planks (10?) or one complete base plank (10?) shaped such that when a plurality of containers are stacked, the bottom of an upper container (1) rests on the flat element (10, 10?, 10?) of a lower container. The flat element (10, 10?, 10?) acts as a support surface for an upper container when it is stacked and as a reinforcement of the container structure, giving it strength and avoiding breakage during stacking.

Abstract: Packaging comprising separate laminar bodies that form the base with opposing parallel sides and two pairs of side walls (2-3) that have, near the lower edges thereof, slots (5) into which tabs (4) on the edges of the base fit, the side edges of the second pair of side walls (3) having further tabs (4?) that fit into further slots (5?) made near the side edges of the first pair of side walls (2), the tabs (4-4?) having harpoon-shaped retention stops that hook over areas adjacent to the ends of said slots (5-5?) made in all the side walls (2-3). The packaging may also include a flat element at the top (10, 10?, 10?) that acts as a lid for the packaging and makes the structure of the packaging more sturdy.
