Abstract
Abstract A device for dispensing moistened tissue web including a container having a dispersing slot and a clamping or cutting mechanism spaced outwardly from said slot for assisting in severing the web into individual sheets after the web has been withdrawn through the slot. The clamping mechanism includes a blade member and a back-up or contact member movable with respect to one another to clamp the web therebetween. In a preferred embodiment, the back-up member is constructed of elastic material permitting the protrusion of the blade into the back-up member to assure extension of the blade edge through the tissue web. Another preferred embodiment of the invention includes a notch formed in the back-up or contact member to permit the blade member to extend into the slot through the tissue web in such manner as to apply large clamping forces on the tissue to facilitate tearing off of the tissue. The blade member and the contact member are mounted at one of the container for the tissue web and a pivotally mounted lid member on the container. The lid member extends over that portion of the container between the slot and the clamping mechanism so as to prevent dehydration of that portion of the tissue extending between the slot and the clamping mechanism. The entire dispensing structure may advantageously be constructed of synthetic resinous material, or alternatively, the blade member may be of metallic profile construction embedded in the synthetic resinous material of either the lid member or the container. The blade member may advantageously be serrated to form perforations in the tissue.
