Abstract

Abstract The invention relates to a gas-inflatable body provided with an opening that can be closed off with a valve and a packaging comprising said body, which valve comprises: an outer plate with a gas passage that is arranged on the body around the opening such that the gas passage lies opposite the opening; a flat inner plate provided with a bore-hole and arranged on the interior of the body with the bore-hole over the opening; a flat valve body located between the outer plate and the inner plate and having a central valve body portion with which the gas passage in the outer plate can be closed off, and having at least one gas inlet located outside the central valve body portion and inside the gas passage; and a resilient sealing located around the gas passage between the flat valve body and the flat inner plate, on which sealing the valve body rests bent and tensioned - with the valve in closed position - with its central valve body portion, preferably the surface area of the opening in the body is equal to or greater than the surface area of the bore-hole in the inner plate, and the flat inner plate and the flat valve body form one entity, and are connected to one another via wings extending laterally from the valve body, whereby adjoining wings together with relevant edge parts of the valve body and of the bore-hole define a gas inlet.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 160 words
A gas-inflatable body provided with an opening that can be closed off with a valve, which valve comprises: an outer plate with a gas passage that is arranged on the body around the opening such that the gas passage lies opposite the opening; a flat inner plate provided with a bore-hole and arranged on the interior of the body with the bore-hole over the opening; a flat valve body located between the outer plate and the inner plate and having a central valve body portion with which the gas passage in the outer plate can be closed off, and having at least one gas inlet located outside the central valve body portion and inside the gas passage; and a resilient sealing located around the gas passage between the flat valve body and the flat inner plate, on which sealing the valve body rests bent and tensioned - with the valve in closed position - with its central valve body portion.
Claim 2
Dependent Claim 160 words
A gas-inflatable body provided with an opening that can be closed off with a valve, which valve comprises: an outer plate with a gas passage that is arranged on the body around the opening such that the gas passage lies opposite the opening; a flat inner plate provided with a bore-hole and arranged on the interior of the body with the bore-hole over the opening; a flat valve body located between the outer plate and the inner plate and having a central valve body portion with which the gas passage in the outer plate can be closed off, and having at least one gas inlet located outside the central valve body portion and inside the gas passage; and a resilient sealing located around the gas passage between the flat valve body and the flat inner plate, on which sealing the valve body rests bent and tensioned - with the valve in closed position - with its central valve body portion.
Claim 3
Dependent Claim 32 words
Body as claimed in claim 1, wherein the surface area of the opening in the body is equal to or greater than the surface area of the bore-hole in the inner plate.
Claim 4
Dependent Claim 55 words
Body as claimed in claim 1 or 2, wherein the flat inner plate and the flat valve body form one entity, and are connected to one another via wings extending laterally from the valve body, whereby adjoining wings together with relevant edge parts of the valve body and of the bore-hole define a gas inlet.
Claim 5
Dependent Claim 22 words
Body as claimed in claim 3, wherein the wings are arranged diametrically and in rotation symmetry around the central valve body portion.
Claim 6
Dependent Claim 33 words
Body as claimed in claims 1-4, wherein the cen­tral valve body portion is provided - in the closed position of the valve - with a valve body guiding extending into the gas passage.
Claim 7
Dependent Claim 37 words
Body as claimed in claims 1-4, wherein the valve body is furnished with a tool seating for a tool accessible via the gas passage, with which tool the valve body can be lifted from the outer ring.
Claim 8
Dependent Claim 26 words
Body as claimed in claim 1 or 2, wherein the flat valve body is a resilient valve foil lying between the inner plate and the body.
Claim 9
Dependent Claim 19 words
Body as claimed in claim 7, wherein the gas inlets are located between the valve foil and the body.
Claim 10
Dependent Claim 18 words
Body as claimed in claim 7 or 8, wherein the gas inlets are arranged in the valve foil.
Claim 11
Dependent Claim 25 words
Body as claimed in claims 7-9, wherein the gas inlets are arranged in the valve foil in rotation symmetry around the opening in the body.
Claim 12
Dependent Claim 25 words
Body as claimed in claims 1-10, wherein the body is enclosed by a packaging and wherein the outer plate is incorporated in a packaging wall.
Claim 13
Dependent Claim 19 words
Body as claimed in claims 1-11, provided with body portions forming a protective shield around an article for packaging.
Claim 14
Dependent Claim 11 words
Body as claimed in claims 1-12, provided with concertina-shaped body portions.
Claim 15
Dependent Claim 10 words
Packaging provided with a body as claimed in claims 11-13.
