Abstract
Abstract A frangible ampoule can be inserted into a hole in which an object is to be anchored, and contains a first component of a two-component adhesive. A second component of the adhesive is externally adjacent the ampoule and so arranged as to be intermixable with the first component upon breakage of the ampoule.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
An adhesive cartridge for anchoring of an object in a hole, comprising an outer frangible ampoule adapted for insertion into a hole and having an inner circumferential surface; an inner frangible ampoule received in said outer ampoule with radial clearance and having an outer circumferential surface; a first component of a two-component adhesive accommodated in said inner ampoule; and a strip of a second component of said adhesive helically convoluted on one of said surfaces, surrounding said inner ampoule and extending substantially across said clearance towards the other of said surfaces, the convolutions of said strip being spaced from one another so as to facilitate intermixing of said components upon fracturing of said ampoules.
Claim 2
Dependent Claim
114 words
An adhesive cartridge for anchoring of an object in a hole, comprising an outer frangible ampoule adapted for insertion into a hole and having an inner circumferential surface; an inner frangible ampoule received in said outer ampoule with radial clearance and having an outer circumferential surface; a first component of a two-component adhesive accommodated in said inner ampoule; and a strip of a second component of said adhesive helically convoluted on one of said surfaces, surrounding said inner ampoule and extending substantially across said clearance towards the other of said surfaces, the convolutions of said strip being spaced from one another so as to facilitate intermixing of said components upon fracturing of said ampoules.
Claim 3
Dependent Claim
15 words
A combination as defined in claim 1, wherein said second component is of pasty consistency.
Claim 4
Dependent Claim
18 words
A cartridge as defined in claim 1, wherein said second component is applied on said inner circumferential surface.
Claim 5
Dependent Claim
89 words
An adhesive cartridge for anchoring an object in a hole, comprising an outer frangible ampoule adapted for insertion into a hole and having an outer circumferential surface formed with substantially uniformly distributed recesses; an inner frangible ampoule received in said outer ampoule with radial clearance a first component of a two-component adhesive accommodated in said inner ampoule; and a strip of a second component having convolutions located in said recesses and spaced apart from one another so as to facilitate intermixing of said components upon fracturing of said ampoules.
Claim 6
Dependent Claim
89 words
An adhesive cartridge for anchoring an object in a hole, comprising an outer frangible ampoule adapted for insertion into a hole and having an outer circumferential surface formed with substantially uniformly distributed recesses; an inner frangible ampoule received in said outer ampoule with radial clearance a first component of a two-component adhesive accommodated in said inner ampoule; and a strip of a second component having convolutions located in said recesses and spaced apart from one another so as to facilitate intermixing of said components upon fracturing of said ampoules.
