Definitions

• the invention relates to a strap, for example for detergent carrier packages, and provided with this strap carrying package and a method for producing the carrying strap according to the invention.
• such straps are as an elongated strip of a flexible material, in particular plastic, formed, which is fastened via rivet joints on the support package, which is often formed from a folding blank of cardboard and / or corrugated cardboard.
• the rivet connection it is possible to rotate the strap so that it rests in a transport position on a side or jacket wall of the carrying package and can be rotated for carrying in a position above the head of the package.
• Such a belt is known for example from JP2003192011.
• the carrier belt disclosed therein is formed by extrusion of a plastic mixture consisting of 40 to 60% by weight of polypropylene and 40 to 60% by weight of a thermoplastic elastomer (TPO), wherein the extruded carrying belt is then monoaxially stretched to improve its carrying capacity.
• TPO thermoplastic elastomer
• a disadvantage of this solution is that on the one hand relatively large amounts of plastic for the production of the belt are needed and on the other a satisfying, comfortable feel can not be set, as the surfaces produced according to JP2003192011, especially in the edge region of the strap regularly as yet to be felt too hard.
• Another way to improve carrying handles is to make the belt multi-layered, sandwich-like, with a hard core providing the carrying capacity of the belt while a casing formed by a soft material provides a comfortable grip.
• a belt is disclosed, for example, in US4047263.
• a disadvantage of the soft-feel strap described in US4047263 is that it can not be produced in one production step, since the supporting hard core of the handle is encased in a second process step with the soft material and with the Core must be fixed so that the softer outer layer does not dissolve when worn from the core.
• the object of the invention is therefore to develop a strap, especially for detergent carrier packets, which avoids the disadvantages described above and is characterized despite a high tear resistance by a pleasant to the user feel, local pressure peaks while carrying on the user's hand as far as possible avoids and easy to manufacture.
• the tube from which the strap is formed preferably has an approximately circular cross-section. But there are also other, any cross-sectional shapes such as ellipses, rectangles, polygons, etc. conceivable.
• the loops have a height (H) which is greater than the height (h) of the tube sections fixed against each other on the one hand, a larger surface for distributing the forces occurring is provided and on the other hand, the enclosed loop space forms an additional spring action of the strap at the width ends, thereby occurring voltage spikes, in particular if they can jerkily occur, for example, when lifting a load on the strap, be cushioned.
• the opposite tube sections of the tube inside abut each other, i. the inside of the hose touch each other. This can be effected for example by a simple compression of the hose.
• the opposite sections of the tube inside are cohesively, in particular by gluing or welding, fixed against each other.
• gluing or welding it is conceivable first to apply a suitable adhesive to the inside of the tube and then to join the corresponding sections together in a material-locking manner by compressing the tube.
• the tube from which the strap is formed may be formed in one piece or several pieces.
• the opposing sections of the inner side of the hose may be spaced apart from one another by at least one intermediate insert in the mutually fixed state.
• the intermediate insert may in particular be designed as a strip-shaped element that extends in whole or in sections over the length of the carrying strap.
• the intermediate insert is designed as an inner tube inserted into the outer tube.
• the intermediate insert may in particular be connected by a material connection with the adjacent inner sides of the hose.
• the intermediate insert may be formed of a material of greater Shore A hardness than the surrounding tube.
• the intermediate insert from a monoaxially oriented polypropylene.
• the strap is formed flexible.
• flexible means in general the property of the carrying strap to be flexible or deformable.
• the flexibility of the carrying strap can be realized by a suitable choice of material and / or material combination and / or a suitable structural design of the carrying strap.
• the materials of the carrying strap can not impart a feeling of comfort which is pleasant for the user due to a suitable choice of hardness, elasticity, heat capacity and surface finish.
• Thermoplastic elastomers or LDPE are particularly suitable as materials for the carrying strap.
• the outer tube consists of a foamed plastic.
• the foamed material may have an open and / or closed-cell structure.
• the cell size can in this case also have a gradient in order to make the grip section softer by larger cells in the outer region.
• foaming it is also possible to provide a comfortable grip, with reduced material usage.
• the outer tube may in particular also be designed as a "soft-feel" surface.
• the strap may have structures in any shape suitable for causing a local reduction in the flexural stiffness of the wearer's cross-section such that the wearer's cross-section deforms preferentially at the locations where the structures are formed on or in the strap-belt cross-section to follow the user's hand while carrying the contour and to achieve the most even pressure distribution over the strap cross section on the user's hand.
• the structures may be formed, for example, as depressions, notches, joints, cracks, grooves, grooves, cuts, holes, channels, gaps, cavities, dents, indentations, depressions, openings and the like.
• the structures may be oriented longitudinally on or in the strap belt surface.
• a significant advantage of the arrangement in the longitudinal direction is the formation of the same bending properties of the support belt cross-section profile over the entire length of the belt.
• the longitudinal arrangement is particularly suitable for structures such as notches, seams, scratches, grooves, grooves, channels, and the like, which structures extend in cross-section from a surface toward or away from the center of the wearer belt cross-section.
• the structures are oriented substantially transversely on or in the strap.
• notches, cuts, gaps, indentations may extend directed from the end faces towards the center of the strap.
• Multilayer construction By a multi-layer construction of the belt, it is possible to fasten the belt to the support package by rivets, without the risk that the belt breaks at the attachment point, especially when the belt is pivotally mounted on the support package by the rivet connection.
• a slot in the belt that can be performed in a riveted joint. If the material is too soft, there is a risk that the rivet will slip out of the slot guide when the belt moves along the slot due to spreading of the slot walls. Due to the multi-layer structure of the belt and the formation of the slot in the core of the belt, a spreading of the slot walls is prevented and the rivet safely guided in the slot.
• the intermediate insert and the tube sections can be firmly connected to one another in a further embodiment of the invention.
• the connection may be formed in shape, force, and / or material fit.
• the connection can be made by a material bond such as gluing, hot-joining, heat sealing, welding or the like. It is very particularly preferred to bring about the connection of the intermediate insert and the tube sections during or immediately after a coextrusion.
• the intermediate insert and the hose are configured in such a way that, when a load on the strap is worn properly, a convex deflection of the strap cross-sectional profile is effected at least in the grip area and thus a uniform pressure distribution on the user's hand.
• a convex deflection of the carrying belt cross-section profile means a deformation of the carrying belt cross-section along a bending line, which substantially corresponds to an upwardly open parabola.
• the strap has an intermediate insert, which has higher strength values, in particular a higher flexural rigidity, compared to the tube surrounding the intermediate insert.
• a suitable parameter for determining the strength of materials in this context is the Shore A hardness.
• the tube from which the strap is formed is advantageously extruded. Due to this quasi-continuous production method, a very cost-efficient production of the carrying strap according to the invention, in particular with a core, is possible.
• Coextrusion is the continuous production process of multi-layered profiles of two different plastics, wherein the plastics heated to fluidity are ejected from two or more nozzles at the same time and shortly afterwards combined to form a multi-layered profile.
• the strap is intended especially for use with carrying packages.
• a carrying package is filled with a detergent or cleaning agent.
• a carrying package in the sense of this application comprises any packaging means which is suitable for receiving a washing and / or cleaning agent and on which a handling aid in the form of a belt is pivotably arranged at two points of the packaging means.
• a carrier package may be selected from the group of boxes, boxes, pouches, cans, bottles or barrels.
• a carrying package may be formed as a folding box, which form from a blank by folding a suitable container for receiving a filling material, such as Aufrichtschachteln, passage boxes, Faltêtschachteln, Falthüllenschachteln, cartons with inner lining, belt folding boxes, Schiebefaltschachteln, Steckêtschachteln, Stülpdeckelfaltschachteln and Aufsatzdeckelschachteln, window boxes, Cap boxes such as cover cap boxes or Rändelkappenschachteln, and Laschendeckelschachteln, hull boxes, sliding boxes, chip boxes, slip-lid boxes, carrying boxes or shipping boxes understood.
