Definitions

  • the present invention relates to an inflatable type shock absorbing package body, which can be used repeatedly.
  • any of the shock absorbing materials had not sufficient effect of holding the goods to be transported steadily at a predetermined position and giving no shock nor any strong vibration to the goods to be transported and, moreover, has been required to be formed every time according to the shape of the goods to be transported and, therefore, had a drawback of making a mass production difficult due to complicated constitution.
  • shock absorbing materials which are apt to be scattered have been used, so that there have been drawbacks such as disposal thereof after use being annoyance, reuse thereof being not possible and recycling of precious resources being difficult.
  • shock absorbing materials utilizing air bags such as represented by Japanese Utility Model Application Laid-Open No. 4-27771.
  • Each of these materials had a plurality of air bags formed in a cylindrical shape and inserted a material body into the inside thereof and filled the inside with air so as to hold the material body by expansion.
  • These bags were provided with a check valve and were constructed in such a manner that air once filled was not leaked.
  • an inflatable body according to the invention aims to solve the above described drawbacks of the conventional examples and to provide an inflatable type shock absorbing package body, which holds the goods to be transported steadily at a predetermined position, and which not only gives no shock nor any big vibration to the goods to be transported, but also can be usable regardless of the shape of the goods to be transported and can still maintain such a performance for an extended period of time.
  • the inflatable type shock absorbing package body is an air bag comprising an automatic closedown check valve and at least a pair of opposed air chambers comprising flexible sheets, wherein both sides of a passage body capable of opening and closing and comprising flexible sheets are clipped by a support body in a state of being curved at a predetermined curvature and an elastic material adherable to this support body, or alternatively the passage body and the elastic material are clipped by the support body in the shape curved at a predetermined curvature and a lid body and connected together by connecting means, and the elastic material is pressed along the support body in a curved state by the lid body at a predetermined curvature so that the passage body is closed in a normal state, and when a bar-shaped body is inserted into the inside of the passage body between the support body and the elastic material, the elastic material is deformed so that the passage body is opened, and when the bar-shaped body is extracted, the elastic material adheres to the support body by resilience so that the passage body is closed, and wherein
  • a pair of opposed air chambers has the following characteristics.
  • a high performance automatic closedown check valve is used so that the goods to be transported are steadily held at a predetermined position and, moreover, not only no shock nor any big vibration is given to the goods to be transported, but also the package body can be used regardless of the shape of the goods to be transported and, moreover, such a performance can be kept for an extended period of time.
  • the automatic closedown check valve has a sufficiently sustainable durability, the performance as a shock absorbing material can be kept for an extended period of time.
  • Figure 1 is a front view (a) and a bottom view (b) of the inflatable type shock absorbing package body according to the invention.
  • Reference numeral 3 denotes an automatic closedown check valve (hereinafter, referred to as a check valve).
  • air chambers 4, 5 are arranged face to face and constitute a nearly cylindrical body in the state (normal state) prior to air being filled into the air chambers.
  • the air chambers are communicated and the check valve 3 is provided on the other side thereof.
  • both of the air chambers are gradually inflated, and a sheet 6 which constitutes an inner wall adheres to the object 2.
  • the object 2 is fixed nearly at the center of the package body 1.
  • FIGS. 2 to 5 explain several structural examples of the inflatable type shock absorbing package body according to the invention.
  • Figure 2 is a first structural example and shows a case where three pieces of flexible sheets are used.
  • three pieces of flexible sheets totaling one piece of the sheet (7) constituting an inner wall twice-folded and two pieces of flat plate like sheets (8A, 8B) constituting an outer wall are prepared.
  • a width A of the twice-folded sheet 7 is smaller than the widths A of other sheets 8A, 8B. This is because, when three pieces of the sheets are superposed and the periphery thereof is welded, a folded portion 9 of the sheet 7 is not welded so that that portion is made to be a communication portion of the air chambers.
  • the check valve 3 is provided on the folded portion of the sheet 7, as shown in (c), it may be, of course, provided on the end portion at an opposite side. Even in that case, the folded portion 9 of the sheet 7 is not welded with the sheets 8 so that it may be secured as an air communication portion.
  • the same drawing (d) is a front view of the package body in the normal state, and (e) is a sectional view of the package body, which is in a state of having crushed a cylindrical body.
  • the material of the flexible sheet can be selected from a plastic sheet, a metallic sheet or a composite sheet made of these sheets as components.

  • These flexible sheets or composite sheets are taken as materials, and two pieces of the material sheets are bonded together and the periphery thereof is heat-sealed at a predetermined width, so that the sheets are heat-welded and formed.
  • the material in which the outside layer is polyethylene or polypropylene, and the inner layer is nylon resin or polyester a so-called a laminated material having a multi-layer structure may be taken as the material.
  • Figure 3 is a second structural example and shows a case where two pieces of the flexible sheets are mutually twice-folded and used.
  • the sheet 7 constituting the inner wall and the sheet 8 constituting the outer wall are prepared (a).
  • the width in the sheet 8 is larger than that in the sheet 7. This is because of the same reason as that of the structural example shown in the preceding drawing.
  • Each sheet is twice-folded and each end portion is arranged face to face.
  • the sheet 7 is inserted into the twice-folded sheet 8 (b) and moreover, the check valve 3 is inserted and welded along the periphery of the sheet 8 (c).
  • Figure 4 is a third structural example and shows a case where a cylindrical sheet is used.
  • the cylindrical sheet like (a) is prepared, and the check valve 3 is inserted in the end portions and the two end portions 10 are welded.

  • the same drawing (d) is a front view of the package body, and is in a state of having crushed a cylindrical body.
  • the reason why the dimensions of the portion 7 and the portion 8 are made different so as to provide the end portion 12 is because, for example, this flexible sheet is the composite sheet and, in the case where the near side of the paper is made of a heat-weldable material such as polyethylene and polypropylene and the rear side of the paper is made of the material not heat-weldable such as nylon, it is necessary to combine the materials mutually heat-weldable. Accordingly, in the case where a single material which is heat-weldable is used, the dimensions of the portion 7 and the portion 8 are quite the same and there is no need to form the end portion 12.

  • one piece of the flexible sheet provided with the portion 7 constituting the inner wall and the portion 8 constituting the outer wall is prepared.
  • the reason why the width of the two portions is different is because, in the case where the flexible sheet as the material is a material laminated by polyethylene resin (PE) and nylon resin (NY), polyethylene is allowed to be mutually welded. That is, in the drawing, the sheet is folded in such a manner that the outer side is nylon resin and the inner side is polyethylene resin. Note that, in the case of the single material sheet comprising polyethylene only and the composite material such as PE-NY-PE, since the nylon resin which is unable to be welded does not contact with each other, the two portions may have the same width.
