## Abstract

An ostomy appliance for receiving waste is described including: first and second walls connected to each other at or near their peripheries, the first wall having a stoma-receiving opening; a waste collecting cavity defined between the first and second walls; a first weld portion positioned to one side of the appliance and which connects the first and second walls together, which first weld portion extends away from a periphery of the appliance and downwardly towards a bottom of the appliance; and a second weld portion positioned on an opposite side of the appliance to the first weld portion and which connects the first and second walls together, which second weld portion extends away from a periphery of the appliance and downwardly towards a bottom of the appliance.

b) wherein the first and/or second weld portion is an extension or continuation of the peripheral connection of the first and second walls;
c) wherein the first and/or second weld portion is generally arcuate or a portion thereof is generally arcuate;
d) wherein the first and/or second weld portion is generally curvilinear;
e) wherein the first and/or second weld portion is generally elongate;
f) wherein an end of the first and/or second weld portion remote from the periphery of the appliance is curved or rounded.

### Claim 3 (depends on 1)

### Claim 5 (depends on 1)

The closed colostomy appliance according to claim 1 wherein the first weld portion is elongate and has an axis B that extends lengthways thereof substantially midway therethrough, said axis B being inclined at an angle α to an axis C that extends along the peripheral connection of the first and second walls to each other.

### Claim 6 (depends on 5)

The closed colostomy appliance according to claim 5 wherein angle α is less than 90°; or
wherein the third weld portion is elongate and has an axis D that extends lengthways thereof substantially midway therethrough, said axis D being inclined at an angle θ to an axis E that extends along the peripheral connection of the first and second walls to each other.

### Claim 7 (depends on 6)

The closed colostomy appliance according to claim 6 wherein angle θ is less than 90° and/or angle θ is greater than angle α.

### Claim 8 (depends on 1)

The closed colostomy appliance according to claim 1 wherein the second weld portion is elongate and has an axis B that extends lengthways thereof substantially midway therethrough, said axis B being inclined at an angle α to an axis C that extends along the peripheral connection of the first and second walls to each other, wherein angle α is less than 90°.

### Claim 9 (depends on 8)

The closed colostomy appliance according to claim 8 wherein the fourth weld portion is elongate and has an axis D that extends lengthways thereof substantially midway therethrough, said axis D being inclined at an angle θ to an axis E that extends along the peripheral connection of the first and second walls to each other, wherein angle θ is less than 90°.
