  • Patent number: 4498609
    Abstract: A dropper, press fitted into the neck of a cyanoacrylate adhesive dispensing container, includes an elongated nozzle having a constant diameter passageway. The inlet to the nozzle is defined by a downwardly depending hollow boss having a sharp edged perimeter and sharp edged orifice. The sharp edged orifice and sharp edged perimeter tend to discourage retention of any droplets of cyanoacrylate adhesive to maintain the inlet free of residual cyanoacrylate adhesive and free of the crusting and clogging of the inlet which might otherwise occur.

  • Patent number: 4413753
    Abstract: A constant diameter or segmented constant diameter passageway within a dispensing tip channels and dispenses a cyanoacrylate adhesive from a container through a discharge outlet at the extremity of the tip. A stopper for the tip includes a plunger for matingly and penetrably engaging the passageway to force reverse flow of the cyanoacrylate adhesive back into the container. The forced flow, due to the viscosity and surface tension characteristics of the cyanoacrylate adhesive, initiates complete drainage of the passageway and prevents any crusting and clogging of the cyanoacrylate within the passageway. The stopper is manufactured attached to the end of the tip at a weakened junction for breakaway separation by the ultimate user, which junction insures the establishment of a sharp edged discharge orifice at the tip to promote accurate dispensation of cyanoacrylate adhesive and to prevent clogging of the orifice.

  • Patent number: 4408699
    Abstract: A constant diameter passageway within a dispensing tip channels and dispenses a cyanoacrylate adhesive from a container through a discharge outlet at the extremity of the tip. A cap for the tip includes a plunger for matingly and penetrably engaging the passageway to force reverse flow of the cyanoacrylate adhesive back into the container. The forced flow, due to the viscosity and surface tension characteristics of the cyanoacrylate adhesive, initiates complete drainage of the passageway and prevents any crusting of the cyanoacrylate within the passageway and clogging of the passageway.

  • Patent number: 4334638
    Abstract: A two phase interlock secures a cap to a container of a fluid. The interlock includes flanges extending from the cap for engaging lugs located about the mouth of the container which flanges are disengageably engagable with the lugs by rotating the cap relative to the container and a key extends from the cap into a key way in the container to prevent rotation of the cap relative to the container without withdrawal of the key from the keyway by deliberate precise flexing of the cap.

  • Patent number: 4297160
    Abstract: Thread locking compositions and analogous sealant materials having limited cured strength, and a preferred method for their compounding and application, are disclosed. These are based primarily on alpha cyanoacrylates, i.e. acrylate esters in monomer or low polymeric form, or of very low molecular weight, which are rapidly polymerizable to form solid and bonding films. The materials, in liquid form, are modified by inclusion of coloring agents and other film strength and reaction rate modifiers, to impart optimum properties of bonding strength, curing rate, moderate resistance in torque to separation of the bonded parts, low residual torque, along with good stability in storage, or good shelf life. Combinations of polymerization promoters and stabilizers are included, along with small quantities of specially selected coloring agents which not only impart effective color to thin films of the composition but serve to limit curing below high cured strength.

  • Patent number: 4215173
    Abstract: Adhesive bonds between materials, such as woods having porous surfaces, formed by polymerizing in situ alphacyanoacrylate monomers, are accelerated in curing and strengthened by precoating the surfaces to be joined with a solid mixture of alkaline or basic accelerator, such as sodium or potassium hydroxide or sodium borosilicate spheres of micro-size, combined in a chalkable calcareous binder to form a light but adhesive permeable coating, before the monomeric adhesive is applied. The latter permeates in part through the light precoating to bond into the wood and is accelerated in its polymerization so that it is not excessively absorbed into the porous substrate, resulting in a bond of superior strength.
