Flexible package and a method of tearing the same apart

Abstract

A bag-like flexible package is provided which is made of a flexible sheet capable of preventing unintended breakage, has good packing operation workability and a good stability of holding shock-absorbing materials, and exhibits a good workability for operations of suspended ceiling installation and wall mounting installation. The flexible package is made of flexible sheet and has a bag-like configuration having opening at one end thereof whereby it can receive goods therein that are inserted through opening. The flexible package has outwardly convex ridges, outwardly concave valleys, and notches formed on opening. Ridges and valleys are alternately arranged on flexible sheet , and extend in a direction that is orthogonal to or that is oblique to opening .

What is claimed is: 
     
         1 . A flexible package made of a flexible sheet comprising a bag-like configuration with an opening at one end thereof, and a notch being formed on said opening, said package being capable of receiving goods therein that are inserted therein through said opening. 
     
     
         2 . The flexible package according to  claim 1 , further comprising outwardly convex ridges and outwardly concave valleys, wherein said ridges and said valleys are alternately arranged on said flexible sheet, and extend in a direction that is orthogonal to or that is oblique to said opening. 
     
     
         3 . The flexible package according to  claim 2 , wherein said ridges and said valleys are parallel to each other. 
     
     
         4 . The flexible package according to  claim 2 , wherein said notch is formed at positions on said opening where said opening intersects with said ridges or said valleys. 
     
     
         5 . The flexible package according to  claim 1 , wherein said flexible sheet comprises a sheet in which a polyethylene film is laminated on a non-cross-linked, high porosity polyethylene foam sheet. 
     
     
         6 . A method of partially tearing a flexible package apart, said flexible package being made of a flexible sheet, and having a bag-like configuration with an opening at one end thereof, the method comprising starting said tearing from a notch formed on said opening as a start point. 
     
     
         7 . The method of partially tearing a flexible package apart according to  claim 6 , further comprising extending a torn-apart portion that is started from said notch as a start point either along outwardly convex ridges or along outwardly concave valleys, wherein said ridges and said valleys are alternately arranged on said flexible sheet, and extend in a direction that is orthogonal to or that is oblique to said opening. 
     
     
         8 . A method of removing goods from a flexible package, said flexible package being made of a flexible sheet and having a bag-like configuration with an opening at one end thereof, the method comprising:
 starting tearing from a notch formed on said opening as a start point;   fixing an attachment member for said goods to a predetermined position of said goods without fully removing said goods from said flexible package; and   removing said goods to which said attachment member is fixed, from said flexible package.   
     
     
         9 . The method of removing goods from a flexible package according to  claim 8 , wherein said goods comprise a projector. 
     
     
         10 . The flexible package according to  claim 3 , wherein said notch is formed at positions on said opening where said opening intersects with said ridges or said valleys.
