Abstract
A method for applying a sealing member to a capsule intended for the preparation of a beverage in a device for making beverages, where the capsule includes a body having a bottom wall a side wall and a flange-like rim which extends from the side wall, comprises a step of applying a charge of sealing composition in a viscous state on the flange-like rim and a step of compression moulding the charge of sealing composition against the flange-like rim.
Claims29
A capsule intended for the preparation of a beverage in a device for making beverages, comprising:
- a body including a bottom wall, a side wall and a flange-like rim which extends from the side wall, wherein the flange-like rim has a rear face, directed towards the bottom wall of the body, and a front face, opposite to the rear face;
- a sealing member, wherein the sealing member covers both at least part of the front face and at least part of the rear face of the flange-like rim;
- and
- a lid joined to the body on the front face of the flange-like rim, wherein the sealing member and the lid overlap in an overlap point.
A capsule intended for the preparation of a beverage in a device for making beverages, comprising:
- a body including a bottom wall, a side wall surrounding a longitudinal axis, and a flange-like rim which extends radially from the side wall, wherein the flange-like rim has a rear face, directed towards the bottom wall of the body, and a front face, opposite to the rear face;
- and
- a sealing member, wherein the sealing member surrounds entirely the rear face of the flange-like rim and a zone of intersection between the side wall of the body and the flange-like rim, wherein the capsule includes a lid, wherein the flange-like rim of the body has a first diameter, and the lid has a second diameter smaller than the first diameter, the lid having a portion in direct contact to the flange-like rim, wherein the sealing member covers both a part of the front face and the rear face of the flange-like rim, and wherein the sealing member is spaced apart from the lid, so that a portion of the front face of the flange-like rim, radially interposed between the sealing member and the lid, is covered neither by the sealing member nor by the lid.
A capsule intended for the preparation of a beverage in a device for making beverages, comprising:
- a body including a bottom wall, a side wall and a flange-like rim which extends from the side wall, wherein the flange-like rim has a rear face, directed towards the bottom wall of the body, and a front face, opposite to the rear face, wherein the body has an external surface comprising a first portion associated with the side wall, and a second portion associated with the rear face of the flange-like rim, the first and second portions meeting at an angle;
- and
- a sealing member distinct from and positioned onto the external surface, the sealing member being attached to at least a part of the second portion of the external surface and surrounding at least part of the rear face of the flange-like rim, wherein the sealing member includes a thermoplastic elastomer, wherein the capsule includes a lid, wherein the flange-like rim of the body has a first diameter, and the lid has a second diameter smaller than the first diameter, the first diameter constituting a maximum diameter of the capsule, and wherein a zone of intersection between the side wall of the body and the flange-like rim is without the sealing member, so that the sealing member, at the rear face of the flange-like rim, is spaced apart from the side wall of the body, wherein the sealing member extends over the rear face of the flange-like rim up to an outer edge of the rear face of the flange-like rim, without extending beyond said outer edge or onto the front face of the flange-like rim.
A capsule intended for the preparation of a beverage in a device for making beverages, comprising:
- a body including a bottom wall, a side wall surrounding a longitudinal axis, and a flange-like rim which extends from the side wall, wherein the flange-like rim has a rear face, directed towards the bottom wall of the body, and a front face, opposite to the rear face, wherein the body has an external surface comprising a first portion associated with the side wall, and a second portion associated with the rear face of the flange-like rim, the first and second portions meeting at an angle;
- and
- a sealing member distinct from and positioned onto the external surface, wherein the sealing member surrounds at least part of the rear face of the flange-like rim and a zone of intersection between the side wall of the body and the flange-like rim,
- wherein the flange-like rim of the body has a first diameter, and a lid of the capsule has a second diameter smaller than the first diameter, the lid having a portion in direct contact to the flange-like rim, and
- wherein the sealing member extends radially away from the longitudinal axis from a first end, located at the intersection between the side wall of the body and the flange-like rim, to a second end, located at an outer edge of the rear face of the flange-like rim, wherein the sealing member extends axially towards the bottom wall of the body, such that the sealing member comprises a radial portion on the rear face of the flange-like rim and an axial portion extending downwardly from said radial portion on the side wall.
A capsule intended for the preparation of a beverage in a device for making beverages, comprising:
- a body including a bottom wall, a side wall and a flange-like rim which extends from the side wall, wherein the flange-like rim has a rear face, directed towards the bottom wall of the body, and a front face, opposite to the rear face, wherein the body has an external surface comprising a first portion associated with the side wall, and a second portion associated with the flange-like rim, the first and second portions meeting at an angle;
- and
- a sealing member distinct from and positioned externally onto the body, the sealing member being attached to at least a part of the second portion of the external surface and surrounding at least part of the rear face of the flange-like rim, wherein the sealing member includes a thermoplastic elastomer, wherein the capsule includes a lid, wherein the flange-like rim of the body has a first diameter, and the lid has a second diameter smaller than the first diameter, the first diameter constituting a maximum diameter of the capsule, and wherein a zone of intersection between the side wall of the body and the flange-like rim is without the sealing member, so that the sealing member, at the rear face of the flange-like rim, is spaced apart from the side wall of the body, wherein the sealing member extends over the rear face of the flange-like rim and further extends around the outer edge of the flange-like rim to cover at least a portion of the front face of the flange-like rim.
