  • a substantially rigid-walled carton 1 made of cardboard contains a pile of books B of irregular generally pyra ⁇ midal shape.
  • an inflatable bag 2 Arranged above the pile of books B is an inflatable bag 2 having an air inlet 3 terminating in a one-way inlet valve 4 extending through an end wall of the carton so as to be externally accessible.
  • the bag 2 is inflated by injecting air under pressure through the valve 4 of the inlet 3. As a result the bag expands to take up the free space left above the books within the carton and so restrains the books from excessive movement when the carton is in transit.
  • the bag By shaping the inflatable bag 2 as shown in Figs. 3 and 4 so that the side walls of the bag have a concertina-like folded form, the bag inflates in a bellows-like manner to occupy a generally parallelepiped space so that as shown in Fig. 2 the marginal portions of the bag tend to expand downwardly around the generally upwardly tapering pile of books B and so leaving a minimum of free space within the sealed carton.
  • the side walls of the bag may have a plurality of concertina-like folds rather than just the single fold provided in the bag shown in Figs. 1 to 4. Referring in particular to Fig. 5, there is shown the shape and arrangement of the valve 4 in the aperture
  • the valve has a central portion 7 of maximum diameter and an end flange 8 to assist in locating the valve in the card- board material of the end wall.
  • the valve itself may comprise any of the conventional types of cheap and efficient inflation valves such as are used in toy footballs and other inflatable items.
  • the bag 20 may simply comprise a pair of wall portions 21,22 sealed together at their edges and provided with an air inlet 23 similar to the air inlet 3 provided in the bag 2.

  • the inflation and sealing device 40 comprises a sector-portion base plate 47 and a matching top plate 48 arranged for receiving the corner C of a bag to be inflated and sealed.
  • the base plate 47 has a concave recess 49 disposed generally centrally of its top surface.
  • a pipe union 50 and flexible pipe 51 are in pneumatic communication with the recess 49 via an aperture 52 in the plate 47.
  • the base plate 47 also carries an electrically insulating block 53 carrying a welding strip element 54 connected through the block 53 to an electrical supply line 55.
  • the top plate 48 acts as a carrier and slide- guide for a central coaxial assembly of an outer clamping ring member 56 and an inner inflating member 57.
  • the central coaxial assembly may be spring-biassed to the clamping position shown in the drawing and while the central assembly described here is manually slidable between a raised or open position and a lowered or clamping position, means may be provided (e.g. an electrical solenoid or pneumatic or hydraulic arrangement) for moving the central assembly between said positions.
  • the inflating member 57 sealingly engages within the clamping ring member 56 by means of an O-ring and has an annular chamber 58 pneumatically connected to a pipe union 59 and pipe 60 which is connected to the flexible pipe 51 at a common junction 61 to the vacuum line 42.
  • the chamber 58 communicates via a ring aperture 62 with a circular recess 63 formed by the clamping ring member 56.
  • the recesses 49 and 63 combine, when the member 56 is in the clamping position to form an inflation chamber for the bag corner C.
  • the inflation chamber is effectively sealed by the clamping action around a circular area except for an access passage 64 defined by the clamping ring member 56 and the block 53 and welding strip element 54 are arranged to extend in an arc across the base plate 47 including the portion across the access passage 64.
  • Extending axially through the inflating member 57 is an inflating nozzle 65 sharpened at its end which projects from the bottom end of the inflating member 57.
  • Secured to the top plate 48 is an -arcuate bridging block 66 extending ovor tho arc dofinod by the top plate and in operation the top plate can be moved to cause the bridging block 66 to urge the top and bottom layers of the bag together at the same time as power is supplied to the element 54 to effect welding.
  • the central assembly 56, 57 is raised by sliding it upward relative to and through the top plate 48 to the open position at which point the bag corner C is introduced into the inflation chamber 49,63.
  • the central assembly 56, 57 is then lowered to the clamping position and clamps the bag corner C over the arc defined by the clamping ring member with the arc being interrupted at the access passage 64.
  • the bridging block 66 is still in its raised position so that the access passage provides pneumatic communication between the bag corner C and the remainder of the bag.
  • Suction is then applied via the vacuum line 42, pipes 51 and 60, chamber 58 and aperture 62 to both sides of the inflation chamber causing separation of the layers of the bag as indicated in broken line in Fig. 11.

  • a flexible synthetic plastics material such as polyethylene (which may have a light- reflecting coating)
  • for specialised applications may even comprise a self-sealing material.
  • the bags described above co-mprise flexible- walled inflatable containers, it is clear that the invention has further application where the flexible- walled container is expandible by some other means than pressurised air inflation for example by means of a synthetic plastics foam injection. Such foam may be settable so that the invention provides a quick and easy means of forming a solid protective cushion around the goods to be packaged.
  • valve 4 would take another form and for example may have retaining flanges at each end the valve being insertable by sliding into an open slot at the top edge of the end wall.
  • an open slot may form part of a keyhold shaped aperture crossing the fold between the end wall and the foldable flap normally provided to form part of the top wall of the carton.
  • a further modification may comprise pre-fitting of the bag within the carton with the valve or bag corner located in a wall of the carton in a more permanent fashion so that in order to place the goods within the carton, either the bag has to be folded to one side or the goods have to be loaded into the carton via an open side opposite the side of the carton across which extends the inflatable bag.
  • cartons (the basic outer protection) are manufactured with a small hole tailored to allow access to the bag 2 - the carton is erected and the goods placed inside to partially fill the carton
  • the air-bag is placed on top of the goods and the valve or one corner of the bag pushed through the hole 4 - the carton is sealed in the normal manner tape, glue, strapping or string
  • the final action is to provide a compressed air supply to the bag and inflate the bag to the required pressure.
  • This process has many different applications within the packaging industry and, of course, with suitable adaptation a standard range of bags can be produced to cover almost any product where the carton is larger than the contents and requires 'stuffing' or 'filling out' to ensure the safe protection of the goods.
  • More than one bag could be used, of course, to provide, for example, a product suspended between two bags, one in the bottom and one in the top. This particular idea is important in, say, the electrical goods industry where such an anti-shock protection would be desirable. It is a matter of course that such a stuffing would act as a water-proofing, a common cause of damage in postal and other shipping methods.

Abstract

Un sac gonflé (2) est utilisé comme calage à l'intérieur d'un carton scellé (1) afin de remplir l'espace qui resterait autrement libre autour des marchandises (B) transportées dans le carton. Le sac est gonflé après la fermeture du carton. Il est possible d'avoir accès à une soupape unidirectionnelle (3) ou à un coin du sac non gonflé par l'intermédiaire d'une ouverture dans le carton, la soupape servant d'entrée de l'air comprimé. Lorsque l'air est introduit simplement à l'aide d'une perforation du coin du sac, ce dernier est scellé après le gonflage. Le dispositif de gonflage et de soudage du sac utilise l'aspiration pour séparer les couches du sac, l'une des couches étant transpercée par un ajutage pointu d'alimentation en air comprimé, qui gonfle le sac. Le coin du sac est ensuite scellé thermiquement.
