Abstract: 1422753 Moistened web dispensers COLGATE-PALMOLIVE CO 7 Feb 1974 [26 Feb 1973] 05630/74 Heading B8M A container 11 enclosing a supply of premoistened liquid-absorbent material 17 in the form of successive sheets connected together by weakened regions is constructed so that during dispensing the leading sheet 18 of the supply extends through an aperture 16 to be grasped by the consumer, at least one projection 22 one or more edges projecting internally of the aperture to engage a weakened region of the supply during withdrawal of the leading sheet. Before the weakened region is fully severed part of the next sheet is drawn out and becomes the new leading sheet. The reasons are said to be (1) the momentum of the pull, (2) the fact that the aperture is wide enough for only the projections to contact the sheet, the projections either being free (i.e. not touching the opposite side of the aperture) as in the embodiments of Figs. 1, 6-11 (not shown) or just touching, Fig. 12 (not shown), and flexible, (3) the lines of weakness between sheets, e.g. perforations, are at 45 degrees to the length of the web of sheets and (4) the length of aperture 16 may be only a fraction of the width of the sheet 18. In the embodiment of Fig. 2, the material is in the form of a roll and is unwound from the centre or the material may be in folded form. Plastics for 11, Fig. 2, may be closed by a plastics cover 12 secured by friction, a screw thread or a bayonet type connection. An integral upstanding hollow boss 14 is closed at its bottom 15 except for aperture 16. A removable cap 20 provides a fluid-tight seal. A liquid 24 containing a cleaning and treating agent is contained at the bottom of jar 11 and is wicked on to the paper or textile sheets 17. In the embodiment of Fig. 13 (not shown) there is no hollow boss or cap and the aperture is sealed before use by a strip (25) backed with pressure sensitive adhesive. A similar strip may cover the aperture 16 in the embodiment of Fig. 2, until the first withdrawal of material. In the embodiment of Figs. 14 and 15 (not shown) the top wall of the container is an integral extension of the side wall. The leading end (18<SP>1</SP>) of the first sheet extends through star shaped aperture 16<SP>1</SP> and is secured to the lower surface of a removable cap 20. In the embodiment of Fig. 16 (not shown) there is no hollow boss or cap and the aperture is sealed until the first withdrawal by a removable wall section (34) outlined to the shape of the aperture by score lines. A lifter tab (25) is attached to section (34), a gas tight easily torn disc (36) is secured to the underside of the top wall for additional initial sealing and the leading end of the first sheet is secured to it. In the embodiment of Fig. 17 the web is unrolled from the outside of a roll whose axis is horizontal and extracted through an aperture 27 in the side wall of container 28. Aperture 27 may be shorter than the width of the sheet but as shown it is longer than the width of the sheet. The aperture is initially closed by a removable wall section 31 outlined by score lines and having lift tab 32. The leading edge of the first sheet is fixed to wall section 31 and an initial seal is provided by an outside coating.
