Abstract:
An extraction bag with support comprising:a bag member formed from a water-permeable filtering sheet for containing a material to be extracted; and a support member formed from a water-resistant sheet for forming a support for said bag member; wherein said bag member has front and back face sections formed by folding said water-permeable filtering sheet into halves along a center line thereof, said front and back face sections continuing to each other at a common top edge thereof, and being joined and sealed together at both their side edge portions and bottom edge portions; said support member is folded into halves along the center line thereof, and has front and back face sections overlapped on the outer sides of the front and back face sections of said bag member, the front and back face sections of said support member continuing to each other at a common top edge thereof, symmetrical to each other, the common top edge of said support member being overlapped on the common top edge of said bag member, and a maximum width of said bag member being larger than a maximum width of said support member; the front and back face sections of said support member are sectionalized into head and leg portions due to folding lines formed in the direction of width thereof, and said head and leg portions can be folded along said folding lines; arcuate push-bending lines are formed at the right and left edges of the continuing head portions of the front and back face sections of said support member passing through said common top edges and reaching the right and left ends of said folding lines, and right and left push-bending portions are formed on the outer sides of the right and left push-bending lines; arcuate rows of perforations for cutting or tearing are formed in the continuing head portions of the front and back face sections of said support member on the inside of said right and left push-bending lines over the front and back face sections of said support member and over the front and back face sections of said bag member held therebetween, so as to be separated away from said right and left push-bending lines, portions for cutting or tearing are formed on the inside of said rows of perforations for cutting or tearing, or the portions for cutting or tearing of the front and back face sections of said support member are cut and torn away, and said arcuate perforations for cutting or tearing are formed in the front and back face sections of said bag member only; the front and back face sections of said support member and the front and back face sections of said bag member in contact thereto are joined together in at least one region of the leg portions; and the portions for cutting and tearing of said bag member and of said support member, or only the portion for cutting and tearing of said bag member when the portions for cutting and tearing of said support member have been cut and torn away, are cut and torn apart along said rows of perforations for cutting or tearing, the right and left push-bending portions in the upper portion of said support member are pushed up or pushed down inwardly along said push-bending lines, whereby the two continuing head portions of the front and back face sections of said support member are push-opened toward both sides of said common top edge, and said portions for cutting or tearing of the bag member are opened and the leg portions of the front and back face sections of said support member are folded down from the push-opened head portions along said transverse folding lines, and whereby the leg portions of the support member supporting the opened bag member are allowed to be placed on the extraction container and the material to be extracted is allowed to be contained in said bag member.
