A laminate tube with an invisible longitudinal overlapped side seam formed from overlap welding an edge of one margin of a laminate sheet comprising an outer plastic layer (A), a barrier layer (B), and an inner plastic layer (C) of the same material type as the outer plastic layer (A) to the other edge of the opposite margin of the laminate sheet, such that an inner surface of the laminate tube has a hump in a overlapped region, while an outer surface of the laminate tube is smooth without a hump in the overlapped region; and a process for manufacturing the laminate tube by a laminate tube manufacturing machine. The laminate permits fracture-proof welding of longitudinal margins of said laminate to give a continuous tube which is suitable for manufacturing of high-quality plastic tubes, high-quality plastic bags and the like.

A container for holding and delivering liquids is disclosed. A method of making the same is disclosed. The container can have a molded container top, a molded container bottom, a flexible film reservoir, and a handle extending from the container top to the container bottom. The reservoir can be laterally exposed around the entire circumference of the reservoir along a part of the longitudinal length of the reservoir. A thermally insulated reservoir system is disclosed. The reservoir system can have a bag having a multi-layered bag wall. The bag wall can have a first layer sealed to a second layer. The volume defined between the first layer and the second layer can be partially or completely filled with a fluid insulator, such as air or saline solution. The volume defined between the first layer and the second layer can also or alternately be partially or completely filled with a solid insulator, such as a matted fiber layer.

Provided is a packaging body for viscous dental material of easy structure, including a container (11) of cylindrical shape whose wall thickness is 0.1 mm to 0.8 mm, including one end closed with a sealed part (12a) that is formed of facing edges of the one end, the edges being joined together; and a viscous dental material (15) filled inside the container, having a consistency of 10 mm to 25 mm.

A multilayer tube laminate for producing a tubular container, having at least one paper layer, a sealable exposed polymer layer on one side of the at least one paper layer, and a polymer coating from an olefin-based material applied directly on the at least one paper layer on an other side of the at least one paper layer facing away from the sealable polymer layer;
the polymer coating being a protective polymer coating with a weight per area in the range from 0.5 g/m.sup.2 to 4.9 g/m.sup.2, where the protective polymer coating is either exposed towards the outside or carries applied printing.

The invention relates to a method for manufacturing a tubular body (2) for a packaging in tube form (1), comprising the following steps: ) definition of the geometrical characteristics of the tubular body (2) to be produced; ) creation of an initial image (6) covering the surface of the tubular body (2) to be produced, said initial image (6) having a right lateral edge and a left lateral edge; ) creation of an intermediate image (8) from the initial image (6) by adding a lateral strip (13) to one of said edges of the initial image (6), said lateral strip (13) comprising a copy of the other of said edges of the initial image (6); ) printing of at least one intermediate image (8) on a sheet, the intermediate image (8) being disposed such that the lateral edges of the image are parallel to the direction of unwinding of the sheet; ) cutting of a small strip on each lateral side of the intermediate image (8) to form a final image (10); ) shaping of the sheet as tubular body (2) and edge-to-edge assembly to obtain a continuity of the design between the right edge and the left edge of the image.

A display system includes a plurality of packets that each include a cavity containing flowable material and a body portion that defines the cavity. The packets each include a header portion and a connector tab, with an aperture established through the header portion. The connector tab of each packet includes a neck portion and a retaining portion, which has a wider cross dimension than the neck portion. The retaining portion of one packet, when received through an aperture of a product or another packet, limits retraction from the aperture to join the packet with the product or other packet.
