Abstract
A liquid container disclosed herein prevents the spattering of ink at the time of peeling a sealing member from a seal surface. A peeling end portion is devised such that the peeling load F gradually decreases as the peeling proceeds over first and second seal surfaces toward an end. The peeling load needs to gradually decrease over a peel ending distance at a rate of at most 0.02 kgf/mm. Such a low peeling load-decreasing rate is realized by gradual width reductions of an end portion of the seal surface, or by predetermining the manner of adhesion between the sealing member and the seal surface, such that the adhesion force per unit area gradually decreases with the progress toward an end of the seal surface. Such slow and gradual reductions in adhesion force allow a user who peels the sealing member to correspondingly adjust the speed of peeling hand movement in a final stage of the peeling. Therefore, at the time when the sealing member finally separates from the seal surface, the sealing member held by the user has been sufficiently loosened back so that substantially no backlash occurs. The spattering of ink from the sealing member and the staining of the surrounding area are thereby prevented.
