Definitions

  • the invention relates to an interconnectable, inflatable packaging material according to the preambles of claims 1 and 4 (GB-A-958 500) and method of its use (claims 8, 9 and 10), wherein objects intended for transport or storage by shock absorbing Cushions or stabilizing inserts are protected from physical influences from the outside.
  • Shaped foam bodies and air-filled bladder materials are well known as cushioning, filling and stabilizing media in the packaging industry and are in widespread use. Such packaging materials are generally transported in large volumes from their manufacturers to the packer, where they occupy a considerable storage space before use. Other, air-filled or foamed packaging materials are manufactured at the packaging site in order to save transport and storage costs. Such materials are unsatisfactory for industrial companies, since additional devices and raw material procurement have to be maintained. In many cases, harmful gases have to be used for foaming. The burden of packaging waste remains with the end user. Disposable materials of this kind pollute waste disposal and landfill sites and raise concerns about environmental protection. Various types of inflatable packaging are known and some of them are suitable for reuse.
  • Ainsworth discloses an inflatable insert in connection with a particular transport container.
  • a pocket element is inserted in the container to transport objects.
  • the container can be closed and a bladder filled with a gas to protect the objects it contains.
  • the container and the bladder can be reused as a means of transport, but Ainsworth's invention has the disadvantage that the gas bladder is only used for a specific container assigned to it and is therefore unsuitable for a differently dimensioned container.
  • Ainsworth's device would be unsuitable for the transport of objects of greater weight, since the gas bubble has no side walls for stabilization and to protect the contained objects.
  • Presnik (US-A-3,889,743) illustrates an inflatable insert for a container, wherein a number of double-walled thermoplastic panels are formed into a mat which, when folded appropriately, can be placed in a suitable container. Individual chambers are connected to each other by channels and one chamber is provided with a valve which should come to rest on the closure side of the container. After this, a gas can be filled in and one or more objects can be inserted into the container padded on the sides without, however, protecting several objects from one another. While this solution may be suitable for a heavier object, Presnik only provides the purpose of isolation for his invention. In any case, this invention also has the disadvantage that a new, suitable mat would have to be made for each container of different dimensions.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of providing a universally applicable, inexpensive to produce, environmentally friendly, easy and clean to use packaging material using stringable, inflatable and repeatedly deflatable Bubbles, which are strung together by means of a combined valve plug coupling, in order to design any object protection and filling packaging, in terms of shape and volume, or to prepare the same for storage or return, in a vented state, to save space and to prepare it for its renewed, easier use to roll up.
  • the advantages achieved by the invention are essentially to be seen in the fact that inflatability and, when not in use, the ability to vent individual bubbles, allow a considerable reduction in volume, which enables the first delivery or return shipment to the packer at low cost.
  • the existing difficulty of waste disposal favors such returns and these, with such a reduced volume, can often be dealt with on public transport routes, which at the same time has a reducing effect on the supply of goods.
  • the packaging material in the sense of the invention, is not difficult with conventional materials and machines, and can be produced more cheaply in terms of price / volume ratio than most conventional packaging, regardless of the possible savings through its reuse.
  • the production of the packaging material according to the invention can be carried out in a completely environmentally friendly manner, and wastes resulting therefrom are completely reusable (recycling).
  • a simple plug-in coupling creates a universally applicable object protection packaging that can be flexibly adapted in terms of design, shape and volume, which can be appropriately and uncompromisingly adapted, in particular for sensitive articles and innovations that are difficult to pack, without special tool costs.
  • the packaging material in different wall thicknesses, the same can also be adapted to extreme loads.
  • the packaging material used in the sense of the invention, completely encases one or more objects and fills cavities in transport containers, so that the packaged objects are displaced, or the packaging is set by vibrations or action from gravitation, as is easily done with commercially available, loose fillers.
  • a packaging according to the invention is characterized by very high shock absorption, which is achieved by relatively large, elastic bubbles, an advantage which is particularly appreciated in the transport of highly sensitive technology and easily fragile goods and which is in need.
  • the bubbles of the packaging material are preferably filled with air, a substance that is freely available to us, which is released undamaged at the destination, which is not the case with foamed materials, and is only achieved with permanently closed bubbles by destroying them.
  • the pressure of the filled bubbles can be regulated during filling and is distributed over relatively large surfaces of a packaged object, whereby a gently low point load is achieved, while the stable elasticity, which is characteristic of the cylindrical bubbles, rubs against object surfaces, as from the application foamed packaging known, almost excludes.
  • the packaging material of the invention can also be used to protect sensitive objects in open transport, such as in a zigzag arrangement of air-filled bubbles between windows in truck transport.
  • an interconnectable, inflatable packaging material and a method of its use is shown, which in its basic structure consists of individual, flexible bladders 14, each with a closed end 22 and a partially closed end 24, a flexible, tubular material of any type large cross-section, closed at intervals of the desired bubble length, by fusion, gluing, or vulcanization 22, or partially closed 24, or bubbles 14/114 according to the invention, by means of molding, in a corresponding manner, or blown.
  • the partially closed end 24 of each bladder 14 is provided with a passage 18 which has an attack bead 13 around its outer wall and a radial groove 19 on its inner wall, and both the opening for filling and venting the bladder 14, as well as the receiver of the combined closure plug coupling according to the invention between two bladders 14.
  • the closed end 22 of each bladder 14 is provided with a plug extension 16 which has an engagement bead 15 and an annular radial spring 17.
  • Both parts, both the passage 18 and the plug extension 16 are tapered in their connection area with the bladder ends 24/22, with the bladder skin 14a / 14b, in order to ensure the necessary elasticity for a rounded inflation of the bladders 14 at these transitions .
  • a bladder 14, preferably with air is filled to a desired pressure through its passage 18 and closed by means of the plug extension 16 of another bladder 14, or if a bladder 14 is used alone, its own plug extension 16.
  • the radial tongue 17 spreads the elastic wall thereof until it can snap into the radial groove 19.
  • the tip of the plug extension 16 is tapered radially and forms a flexible lip 21 which is pressed against the inner wall of the passage 18 by a higher internal pressure within a bladder 14.
  • the completed closure of a bladder 14 is achieved by latching the spring 17 into the groove 19, and at the same time the coupling of two bladders 14. This process can be repeated as often as desired with any number of bladders 14 in order to be able to produce any desired packaging volume. While the bubbles 14 can be of different sizes, the dimensions of Passage 18 and plug extension 16 advantageously held hand and machine, uniform.
  • the closed end 122 of a bladder 114 forms a tongue 123 which surrounds an eyelet 127.
  • the closure plug 116 is firmly connected to the passage 118 by means of a belt-like carrier 125.
  • Two bubbles 114 are attached to one another by pushing the closure plug 116 into the eyelet 124, where it can be easily jammed by means of the conical shape and the groove 126. While this connection is sufficient for venting the bladders 114 and rolling them up, after filling a bladder 114, the closure plug 116 is used for the use of the packaging material, with the tongue 123 being bent into the passage 118 until the radial spring engages 117 pressed into the radial groove 119.
  • the process of coupling together, after debugging, is largely spared with this embodiment, for venting and rewinding, as long as a number of packaging materials have been removed from one container.
  • the bubbles 114 can, if required, be completely separated or replaced by loosening the closure plug 116 of a bubble 114, with little effort, from the eye 124 of another bubble 114.
  • This embodiment also enables transport and storage of large usable volumes of packaging material in an economical, compact manner, since bubbles 114 can be rolled up into a roll 11, a relatively small volume, after venting.
  • the bladders 14/114 are made from a flexible, durable, airtight material such as vinyl or rubber, in accordance with the invention.
  • the wall thickness of the bladder skin 14a / 14b should be selected in use after its loading. Heavy objects require larger material thicknesses.
  • the length and cross-sectional dimensions of the bladders 14/114 can also be determined in accordance with their intended use.
  • various protective shields 130a-130d can be wrapped around an object 142 before packaging, which are preferably made of an unbreakable material such as nylon and are generally rounded on the outside. The particular application depends on the shape of one to be packaged Subject.
  • An elastic tensioning band 131 is tensioned around the object after a protective shield 130a -130d has been attached.
  • a series of bubbles 14 are filled with air, while the passage 18 of each filled bubble 14 is closed with the plug extension 16, another bubble 14, and with continued filling and coupling, a chain of bubbles 14 is produced with which Use the bottom of a shipping container 140 to be lined in a zigzag pattern until this bottom is covered.
  • the end of the last uninflated bladder 14 used to close a bladder 14 advantageously hangs freely over the edge of the container 140.
  • the object 142 is then placed, approximately in the middle, on the mat of bladders 14 produced, before the chain of bladders 14, continued with inflation and coupling, and this, along the lateral circumference of the object 142, is inserted between it and the wall of the container 140 until all sides of the object 142 are sufficiently padded.
  • the chain of bubbles 14 is then extended until, as illustrated in FIG. 8c, the object 142 is completely covered by covering in a zigzag pattern.
  • the shipping container 140 is now ready to receive further items to be packaged or, when it is completely filled with it, to be closed.
  • it is advantageous to coordinate them with one another, taking into account the objects to be packed.
  • a moderate tolerance can be compensated by reducing or increasing the amount of air supplied to the bubbles 14.
  • the object 142 could be surrounded by only a few, relatively long bubbles 14, it is advantageous for sensitive or very valuable objects to divide the packaging into several, shorter bubbles 14 in order to ensure the stability of the packaging, in the event of an unforeseen event Damage to sustain.
  • the remaining bladders 14 can replace the filling volume of a defective bladder 14 with only a slight loss of stability, caused by the urge to take on their unloaded, cylindrical shape under pressure.
  • an object 143 in a shipping container 144, is from enclosed in an individual bladder 14, the bladder 14 being filled with a predetermined amount of air and being airtight at its passage 18 by means of the plug extension 16 of the same bladder 14.
  • the bladder 14 can be filled and blocked before, during, or after the insertion of both parts into the container 144.
  • a stopper identical to the closure stopper 116, but without a carrier 125 is kept ready.
