  • Patent number: 10426939
    Abstract: The invention relates to a liquid applicator sachet comprising a top sheet sealed onto a base sheet such that the sheets define between them, in a reservoir portion, a reservoir for holding liquid, and, in an applicator portion, a conduit extending from the reservoir to an outlet opening. The sachet further comprises an applicator pad that covers said opening. The applicator portion is folded and sealed onto the reservoir portion such that a sharp fold is present between the reservoir portion and the applicator portion. The fold blocks the conduit such that a liquid held in the reservoir is prevented from flowing into the conduit. Furthermore, the applicator portion comprises a grip tab between two tear lines. By pulling the tab, the applicator portion tears along the tear lines and part of the applicator portion can be unfolded to allow liquid to flow from the reservoir into the pad.

  • Patent number: 6050453
    Abstract: The invention relates to an actuator grip provided with a fixed grip part and a trigger part which is pivotally connected thereto and which is drivingly connected to a movable member of an apparatus for actuating by the hand-grip. The pivot connection between the grip part and the trigger part is arranged on the side of the hand-grip remote from the member for actuating. An ergonomically sound and well controllable movement of the trigger part relative to the grip part is hereby obtained, whereby the apparatus connected to the hand-grip can be actuated accurately and with relatively little effort. The invention further relates to a caulking gun which is provided with a container for a medium for dispensing having an outlet aperture and a movable member for urging the medium for dispensing from the container through the outlet aperture, and an actuator grip as described above connected to the container and the movable member.

  • Patent number: 5462633
    Abstract: A dispenser for a tape having a sticky side has a housing adapted to hold a supply of the tape and a roller rotatable on the housing about an axis and having a mainly cylindrical outer surface projecting radially past the housing. The tape passes partially around the roller with its sticky side turned radially away from the roller and engaging a central portion of the roller surface so that the tape can be pressed by the roller against a substrate to adhere the tape to the substrate and to inwardly deflect the central portion of the roller surface. Elements axially flanking the roller permit deflection of the roller surface in contact with the tape inward until the elements contact the surface and prevent further inward deflection of the central portion of the roller surface even if the elements are pressed with greater force against the substrate.

  • Patent number: 5207860
    Abstract: A tape-applying apparatus has a housing adapted to hold a roll of tape, a feed unit actuatable for paying out a piece of the tape, a cutter actuatable for cutting off the piece of tape payed out by the feed unit, an actuating lever displaceable inward and outward between start and finish end positions and through an intermediate position, and a spring braced between the lever and the housing and urging the lever into the start end position. The lever is connected to the feed unit during inward travel of the lever from the start to the intermediate position for actuating the feed unit with the lever and paying out a piece of the tape and is connected to the cutter only during inward travel of the lever between the intermediate and finish positions for cutting off the piece of tape payed out.
