A packaging box is provided, which comprising a box body with a top opening and an openable cover connected at a top of the box body. The box body comprises a bottom wall and a side wall connected to a peripheral edge of the bottom wall, and a top of the side wall forms an arc top edge folding outward. The openable cover further comprises a top wall and a fastening part connected to a peripheral edge of the top wall. A convex rib is formed on the fastening part which matches with the arc top edge. The convex rib blocks at a lower edge of the fastening part. A concave recess is respectively arranged on opposite sides of the side wall. The sealing performance as well as the strength of the packaging box is effectively improved, while the structure of the packaging box is convenient for operation.

Combination flex and torsion springs for use with light weight covers for containers having self-closing gates, the springs operatively connecting the gates to surrounding cover portions. A tri-fold seam including a frangible seam works cooperatively with the flex-torsion springs to implement three modes of operation of the gates. In a first mode, the gate returns to a reclosed orientation after removal of downward pressure. Further pressure on the gate engages a toggle operation that locks the gate open. In a third mode, if the gate is pushed even further downward, the toggle mechanism is defeated and the combination flex-torsion spring is forced past its elastic limit and the gate remains in a permanently open orientation. The flex-torsion springs in accordance with the invention may be fabricated from aluminum sheet stock or spring wire.

The present invention provides a container with double lids, which has a container body, a lid unit to close an open top of the container body, a locking flap provided on either of the container body and the lid unit, and a locking protrusion provided on a remaining one of the container body and the lid unit to lock thereto the locking flap. The lid unit of the container of the present invention includes a locking lid which is made of a soft material and has a predetermined shape to correspond to an edge of the open top of the container body, with an opening provided at an inside part of the locking lid, and a rim-shaped receiving part provided on a lower end of the locking lid to receive therein the edge of the open top of the container body; and an observing lid. The observing lid includes a cover plate to be placed in the opening of the locking lid, and a coupling part extending outward from an edge of the cover plate and to be inserted into the receiving part of the locking lid. Therefore, the container of the present invention allows a user to observe contents of the container through the observing lid, thus being convenient to the user. Furthermore, because the locking lid may be variously colored, the container of the present invention provides the double lids of two tones of color, thus enhancing the appearance thereof.

A unitary, removable, transportation ring for maintaining the closure of a covered container, such as a cylindrical paint can, snaps into place and securely maintains a lid on the container even in an environment of high pressure within the container. The ring is responsively operable in the presence of elevated and extreme pressures within the container to improve the engagement of the ring with the container, and to improve the engagement of the lid with the container, each in order to maintain the cover tightly sealed over the top opening of the container. An annular flange depends from the inner radial margin of the body of the ring and abuts the lid or cover of the container to maintain the engagement of the lid with the container.

The invention concerns a device comprising a pourer, adapted to be mounted on the container neck, and an assembly forming a cover adapted to be mounted on said neck and comprising a cap mobile between a first position where it isolates the neck and the pourer from outside and a second position providing access to the neck and the pourer. The assembly forming a cover comprises two catching string rims (411, 412) extending radially inwards from a ring (41), one first string rim (411) being adapted to be engaged with an external flange (26) of the neck (2) while a second string rim (412) is adapted to be engaged with an external flange (36) of the pourer (3), said string rims (411, 412) defining between them a volume (V) for receiving the flanges (26, 36).

A container lid locking ring is provided to secure the lid of a container to the container and lock one container on top of another. The locking ring comprises a cylindrical ring having a first projection for engaging a recess in the lid of a first container and a second projection, having a finger-like projection, for locking about the rim bead of the container. The locking ring further comprises a seat on which an over disposed container may be placed and a third projection, having a finger-like projection, for locking about the bottom rim bead of the over disposed container. The locking ring may further comprise a fourth projection, providing added locking support and sealing capabilities. In the use of the locking ring, containers may have their lids securely locked onto the container and containers may be securely stacked one on top of another for transportation, storage and display.

The invention relates to a process for the fabrication of a drum made of kraft paper according to which a sheet of kraft paper is rolled on a mandril so as to constitute a rotating cylindrical tube. The end of the tube which forms the bottom is rolled with more than one turn and receives a disk which constitutes the bottom of the drum. The disk is then placed on the ridge (8) formed by the rolled edge, and a retaining collar (10) is placed around the tube. The collar is then tightened to clamp the disk (3A) onto the tube.

The lid seal for wide-mouthed barrels (2) blow-molded of a synthetic resin utilizes a solid sealing ring (9) of plastic, this ring being in contact with the underside of a solid flange (10) projecting radially outwardly at a spacing below the barrel opening from the barrel wall, as well as a counter ring (11 ), likewise produced of plastic, this counter ring resting on a flange (12) molded on the bottom to the outer lid rim (4). Locking sleeves (13, 14) are formed on the clamping rings (9, 11), distributed about the circumference, these sleeves engaging in corresponding bores (15, 16) in the barrel flange (10) and in the lid flange (12). The clamping rings (9, 11) and the locking sleeves (13, 14) molded thereon have conical aligned through bores (17, 18). For closing the lid (1) placed on the wide-mouthed barrel (2), clamping bolts (19) of plastic or metal are pressed, by a pressing tool, from above into the conical bores (18, 17 ) of the two clamping rings (11, 9). The ring (9) in contact with the barrel border (10) is supported by a corresponding device. On account of the clamping force exerted by the clamping bolts (19), the lid gasket (8) is pressed against the opening rim of the barrel neck (3).
