Definitions

  • applicant of the present application has developed a novel self-seal type buffer material which has a flat shape before use and, when inflated by air, has several portions thereof bulging variably and independently in which air blown from outside is confined by a self-seal type valve formed in respetive bulged portions.
  • This type of buffer material may be called "post-inflating" type and is desclosed in my co-pending application, Japanese Utility Model application No. SHO 60-184510 (Laid Open Publication No. SHO 62-93066).
  • This new type of buffer material has several advantages in that it has normally a thin thickness prior to use and can have several portions inflated variably and independently from each other under the influence of surrounding pressures or forces acting thereon.
  • the self-seal type buffer sheet in my co-pending application has relatively complicated structure requiring various components and a large amount of materials, and is relatively expensive to manufacture, all these factors being to be improved.
  • the buffer sheet in my prior application is originally contemplated to be used for covering relatively large areas rather than to be used as narrow strips or as "one point" buffer to be inserted into a small gap and basically is not suited to a vide variety of use.
  • the buffer material in my co-pending application is relatively uneasy to manufacture due to its complicated structure and multiple components as well as delicate manual labor involed therein, and is not adaptable to mass-production processes.
  • Yet another object of the present invention is to provide an inflatable and self-sealable buffer sheet comprising a series of air bags which can be mass-produced with ease and has a vide variety of uses.
  • the inflatable self-seal buffer sheet of the present invention comprises essentially two components, i.e., individual air bags functioning as buffer or retainer and an air blow tube combined therewith functioning as air passage for all of the air bags and also as check valves by themselves so that there are no non- portions of materials present in the buffer sheet of the present invention.
  • the self-sealing check valve according to the present invention is formed by the air blow tube itself, i.e. by slits or slots formed on one flat surface of the tube and by the other flat surface engaging with the slits or slots, so that. it uses minimum of material and is simple in structure, easy to manufacture and most inexpensive.
  • the inflatable and self-sealable buffer sheet illustrated in Figures 6 through 9 is essentially adaptable to the mass-production in that it is readily and efficiently manufactured by relatively simple procedures comprising:
  • partial coatings 26 Between paired partial coatings 26 are formed spaces 30a which are to be aligned with respective link portions 30 between individual air bags 21. Consecutive individual air bags 21 may be devided, if desired or necessary, into a single air bag or two or more consecutive air bags by cutting the same along the intermediate line between adjacent bags as indicated by a broken line 31 in Figure 10, just the same as cutting of the blow tube 2 along the line H-H in Figure 1. In such cases, the cut end of the blow tube need not be sealed for ensuring maintenance of inflated state of devided air bag or bags, while cut ends may of course be sealed for safety purpose.
  • a single continuous buffer sheet comprising a series of individual air bags initially in a flat state can be inserted into uneven spaces, e.g., at the left side of the container in Figure 13, before or after the articles are placed in the container C, and then air is blown into the protruding intake end 22e to inflate the individual air bags 21 1 , 21 2 , 21a and 21 4 independently to the extent that the respective air bags are allowed within the respective spaces of uneven sizes.
  • uneven spaces inside the container can be effectively filled up in a single and simple procedure.
  • spaces of substantially uniform size such as shown at the right .
  • a remarkable feature of the inflatable and self-sealable buffer sheet of the present invention resides in that the individual air bags are independent from each other as to their abilities to expand and maintain expanded states. For example, if any one of air bags is broken, the remaining all of air bags can maintain their fully inflated state without being affected by the broken air bag so long as their self-seal type check valves function. Likewise, any air bags received in larger spaces after or downstream of smaller space can be fully inflated to their own limits irrespective of insuffidiently inflated upstream air bag. Further, any of inflated air bags in series can be taken out by cutting at any desired linking portions without affecting all other bags independently inflated.
