Abstract:
An article of luggage is provided for comprising a first layer of hard shell and a second layer of hard shell material with one or more ornamental substrate disposed between at least the first layer of hard shell material and at least the second layer of hard shell material. A section of hard shell material may be formed by pressing and/or heating at least the first layer of hard shell material, the second layer of hard shell material, and the ornamental substrate together.
Abstract:
A three-dimensional structure composed of pliable elements and having affixed seams is provided. The structure may comprise duffel bags, backpacks, shoe uppers, etc. The structure has a bottom panel with a first terminal bottom portion and a first end panel with a terminal end portion. As well, the first terminal bottom portion and the terminal end portion are affixed to each other in a flattened, two-dimensional arrangement by a variety of attachment methodologies including a thermoplastic elastomer strip. Two-dimensional construction saves time and helps to reduce manufacturing costs.
Abstract:
Die Erfindung betrifft ein Behältnis (1) zum Transport von Gegenständen, mit einer Unterschale (7) und mit einer mit der Unterschale (7) aufklappbar verbundenen Oberschale (7'), die als boxartige Kunststoffteile ausgebildet sind, und mit einem Reißverschluss (6) zum Schließen und Öffnen des Behältnisses (1), der sich wenigstens teilweise umlaufend entlang von einander zugeordneten Randbereichen (11) der Unterschale (7) und der Oberschale (7') erstreckt. Die Erfindung schlägt vor, die Randbereiche (11) der Unter- sowie der Oberschale (7, 7') und die Ränder (9) von Tragstreifen (10) des Reißverschlusses (6) jeweils in einem gegossenen Kunststoffverbindungsprofil (4) einzubetten, das die Reißverschlusshälften (5, 5') des Reißverschlusses (6) mit der Unterschale (7) bzw. mit der Oberschale (7') verbindet. Die Kunststoffverbindungsprofile (4) sind aus einem PUR-Material gegossen, wobei die Ränder (9) der Tragstreifen (10) sowie die Randbereiche (11) der Unter- und der Oberschale (7, 7') und gegebenenfalls Ränder (14) eines Innenfutters (13) beim Gießen der Kunststoffverbindungsprofile (4) in das PUR-Material eingebettet werden. Bei nur teilweise um das Behältnis (1) umlaufenden Reißverschluss (6) erstrecken sich die Kunststoffverbindungsprofile (4) vollständig um das Behältnis (1) und bilden ein Filmscharnier (16), das die beiden Schalen (7, 7') auf- und zuklappbar miteinander verbindet.
Abstract:
A luggage case having a thermoformed shell is made from a thermoformable preform (11) by pressure laminating a layer of cloth fabric (44) to one face of a thermoplastic substrate (42), preferably as the substrate is extruded and while still hot from an extrusion process. The preform (11) should be of a non-stretch type. This non-stretch characteristic, together with its bonding to the thermoplastic substrate (42), prevents the substrate from thinning in the corner regions. The intimately bonded fabric (44) drags or pulls the substrate (42) from a number of directions as the corner regions are formed and the thermoplastic substrate (42) accumulates and thickens in the corner regions resulting in a shell (12) which is durable and aesthetically pleasing.
Abstract:
A method and apparatus are disclosed for producing a hollow article having a plurality of spaced generally concentric walls (50, 60) extending from a common neck (48). To produce the article, a preformed inner vessel (72) defining the inner wall (50) and neck (48) is juxtaposed with a mouldable sheet extrusion (92). Split mould segments (70) are closed around the extrusion (92) to form a substantially sealed parison therein with an annular portion of the parison extending closely around the neck (76) of the inner vessel (72). Fluid pressure medium is introduced via conduit (84) into the space (86) between the inner vessel (72) and the parison to blow mould the outer wall (60) against the moulding surfaces (90) of the mould segments (70). During the blow moulding, the interior of the inner vessel (72) is pressurized with fluid pressure medium via conduit (74) to prevent its deformation.
Abstract:
The invention relates to a rucksack (1), bag or container made of flexible, coated, waterproof and/or non-waterproof materials and which consist of parts that are welded, by overlapping welding, by a tool. The external contours of the tool clamp over the periphery of the base body and the edge becomes part of the overlapping weld seam (2) in the form of a bead. The overlapping weld seam (2) extends along the edge of the periphery (3) and at least one area (4) of the edge of the periphery (3) is longer and the overlapping weld seam (2) in said area (4) is correspondingly further away from the peripheral line (3).
Abstract:
The invention relates to a rucksack, bag or container made of flexible, coated materials produced from cut-out sections. A base part is welded to the cover part and has a closed or semi-open form with overlapping weld seams and a prayer seam on at least one side and said prayer seam is welded by means of a tool and the edge of the cut-out is tensioned by the tool and a cover part is applied.
Abstract:
An inventive solid phase forming process, and related structure, using conventional pelletized thermoplastic compositions to form the elements of a non-textile fabric by coining a single pellet or briquette of the polymer into an individual element in a single forming step. The steps of the process generally include: a) positioning a pellet in or adjacent to a mold cavity, and b) forcing the pellet into contact with the mold surfaces of the mold cavity to plastically deform the pellet to cause the pellet to adapt the shape of the mold cavity. The mold cavity has a shape to form the desired element, and its volume is substantially the same as the volume of the pellet. The forcing step or act preferably uses an energy and speed wherein the pellet superplastically deforms to substantially fill the volume of the mold cavity. This process is repeated with the particular element being formed in the appropriate order to form interconnected plates and rivets, as an example, with the final result being a non-textile fabric. The elements formed by the inventive process can have any of a variety of shapes, and can form base units for the formation of the non textile fabric of two, three or more elements. This inventive process elimininates the need to first form the pelletized polymer into a sheet or other type of preform prior to the forming of the final product.
