<p>A dispensing-sealing arrangement (10) is disclosed for a container (12) comprising a resiliently deformable dispensing apparatus typically in the form of a teat (14) connected about opening (16) of the container (12). The teat (14) is provided with an outlet (18) for dispensing matter contained in the container (12). Cap (20) is provided with a skirt (22) for insertion into the opening (16) for sealing the container (12). Sealing is achieved by the skirt (22) deforming the teat (14) in the manner so that a first portion (24) of the teat is sandwiched between the opening (16) and the skirt (22). The skirt (22) is configured so that sufficient pressure is applied to the teat (14) to ensure positive sealing between the teat and the first skirt (22). The skirt (22) is located in board of the periphery of, and depends from, upper wall (26) of cap (20). Inner surface (28) of skirt (22) together with the portion of the upper wall (26) bound by the skirt (22) defines a recess (32) for engaging a second portion (30) of the teat (14). The second portion (30) is located upstream of the first portion (24) and includes the outlet (18). Engagement of the second portion (30) in recess (32) is achieved by resilient deformation of the second portion against the inner surface (28) of the first skirt (22). When cap (20) is removed, it initially extends the teat (14) from the opening (16) due to the engagement of the second portion (30) in the recess (32).</p> |
