a fiber sheet containing a heat-resistant fiber, of which the melting temperature or the carbonization temperature is at least 300 C.
2. The filtering medium according to claim 1, wherein said fiber is wholly aromatic polyamide fiber.
3. The filtering medium according to claim 1 or 2, wherein said fiber accounts for 3 mass % or more of the entire fibers constituting said fiber sheet.
4. The filtering medium according to any one of claims 1 to 3, wherein said fiber sheet has a coarsedense structure.
5. The filtering medium according to any one of claims 1 to 4, wherein fibers constituting said fiber sheet are bonded by at least a kind of binder selected from a group consisting of rubber-based binders, thermosetting binders, and thermoplastic binders.
6. The filtering medium according to claim 5, wherein said fiber sheet has an area having a large deposit quantity of said binder and an area having a small deposit quantity of said binder.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A beverage bottle particularly adapted for promotional use, comprising:
a body portion having a sidewall portion extending vertically between a neck portion and a base portion, the sidewall portion having a flange portion which peripherally defines a cavity portion, the cavity portion extending a predetermined depth inwardly of the plane of the sidewall portion;
a seal portion disposed over the flange portion and cavity portion of the body portion to sealably enclose the cavity portion, the seal portion provided with a pressure sensitive adhesive for sealing the seal portion to the flange portion, the pressure sensitive adhesive enabling the seal portion to be peeled from and resealed to the flange portion of the body portion; and
a promotional product removably sealed within a storage compartment defined by the cavity portion and the seal portion, the promotional product being frictionally retained within the cavity portion and spaced apart from the seal portion so as to prevent the deformation of the seal portion during the commercial handling of the beverage bottle.
2. A beverage bottle as claimed in claim 1, wherein the cavity portion is defined by a cavity edge extending substantially inwardly from the sidewall portion of the body portion to a recessed cavity wall.
3. A beverage bottle as claimed in claim 2, wherein the plane of the cavity wall of the cavity portion is substantially co-planar with the sidewall portion of the body portion.
4. A beverage bottle as claimed in claim 1, wherein the dimensions of the cavity portion substantially conform to the dimensions of the promotional product so as to frictional engage the promotional product within the cavity portion.
5. A beverage bottle as claimed in claim 1, wherein the flange portion and the pressure sensitive adhesive on the seal portion separate when the storage compartment is peeled open, and wherein the flange portion and the pressure sensitive adhesive on the seal portion adhere when the storage compartment is resealed.
6. A beverage bottle as claimed in claim 5, wherein the material strength of the seal portion is greater than the adhesive strength of the pressure sensitive adhesive to prevent tearing when the seal portion is peeled from and sealed to the beverage bottle.
7. A beverage bottle as claimed in claim 1, wherein the seal portion is adhered to the flange portion of the body portion to form a seal around the cavity portion so that the storage compartment is substantially sealed to exclude air and water.
8. A beverage bottle as claimed in claim 1, wherein the promotional product is sealed within the storage compartment so as not to dislodge uncontrollably during the commercial handling of the beverage bottle.
9. A beverage bottle as claimed in claim 1, wherein the cavity portion is fractionally longer than the promotional product to enable the finger grasping and removal of the promotional product from the cavity portion.
10. A beverage bottle as claimed in claim 1, wherein the seal portion is substantially durable to resist impact forces against the body portion and the promotional product during the commercial handling of the beverage bottle.
11. A beverage bottle as claimed in claim 1, wherein the seal portion is manufactured from a flexible foil material.
12. A beverage bottle as claimed in claim 1, wherein the seal portion is manufactured from a flexible plastic material.
13. A beverage bottle as claimed in claim 1, wherein the promotional product is a whistle adapted to be removed from the storage compartment and releasably secured to the neck portion of the beverage bottle.
14. A beverage bottle as claimed in claim 1, wherein the promotional product is a banner furled around one or more telescopic members and disposed within the storage compartment.
15. A beverage bottle as claimed in claim 1, wherein a liquid beverage within the body portion is maintained separate from the promotional product within the storage compartment.
16. A beverage bottle as claimed in claim 15, wherein the promotional product is a miniature beverage bottle containing a liquor beverage adapted to be removed from the storage compartment and combined with the liquid beverage in the body portion to prepare a mixed liquid beverage.
