  • Patent number: 8087554
    Abstract: An inventive pouring spout that is selectively attachable to a container and fitted to the opening of the container with which it is used. In a preferred embodiment, the pouring spout is fitted to the dimensions of a one-quart container and includes a wall, a sealing member, a mouth and a handle. The handle is connected to the wall with a hinge that enables the handle to pivot away from the container to allow the sealing member to be appropriately positioned while the container rests flat on a surface. After the sealing member is in place, the handle is then pivoted back in position to securely hold the container. The handle includes a plurality of upwardly extending projections adapted to securely engage the bottom rim of the container. Furthermore, thermoplastic material is applied at the handle area forming a handle cover that is comfortable and easy to grip.

  • Publication number: 20100269348
    Abstract: A preferred embodiment of a safety carton cutter comprises a first frame member pivotably connected to a second frame member to form a housing. Inside the housing mounted on the first frame member is a blade receptacle having a latch, a blade carrier, a biasing member and a follower. The follower is adapted to communicate with a cam profile located on a cam in the first frame member. The configuration of the follower and cam profile provides an extending and retracting mechanism that keeps the blade in a constant exposed position before and during the cutting process, and then allows the blade to retract immediately after the cutting process is complete.

  • Patent number: 7815494
    Abstract: A sander comprises a body member molded of polypropylene to which a soft pad member is integrally molded or directly bonded thereto. Preferably, the material comprising the pad member is of a thermoplastic elastomer material, such as Santoprene®. Significantly, when the pad member is molded directly to the body member, the pad has internal dimensions only slightly larger than the external dimensions of the body member so that, when the body member is located within the confines of the pad member, a secure fit is formed between these two members, without any space between them. Further, the respective dimensions of the body member and pad member give the sander a thick, one-piece appearance in side and end views. The pad member may also include a plurality of openings which help provide a “spongy” effect to the user, smoothing the peaks and reaching the valleys of an uneven surface upon which the sander is utilized.

  • Patent number: 7346988
    Abstract: A metallic housing utility knife and method for making the device with a soft over molded elastomeric cover to provide blister free comfort and slip proof safety. The cover or skin is molded into the unique structure of the housing in a fashion that results in mechanical bonds that embrace the cover on the housing. The knife includes flexible posts from the cover that project into the blade storage compartment of the housing to prevent internally stored spare blades from moving within the storage compartment. An elastomeric blade clamp integrally formed with the cover serves to restrict lateral movement of blades of varying sizes when installed in a cutting position within the knife assembly. A rear quick release latch and interlocking housing sections provide a convenient way to open and close the knife and assure that it is also secure and firmly held when locked in a safe cutting position.
