Definitions

  • This invention relates to a portable gun which enables one-component or multi-component flowable substances to be dispensed.
  • the flowable substances are accommodated in one or more aerosol containers.
  • This invention affords a gun for dispensing one or more flowable substances. Because these flowable substances are stored in aerosol containers and feed directly into the gun, the substances may readily be replaced as needed or changed as desired.
  • the gun itself is a triggered device which contains a static mixing chamber where the flowable substances may be mixed before dispensing, and an outlet adapted to the particular application for which the flowable substances are intended.
  • the aerosol pressure f eds the flowable substance into a receiving chamber of the gun, and pulling of the trigger and / or the aerosol pressure forces the one or more flowable substances through a static mixing chamber and then through the outlet.
  • the flowable substance may be a liquid, a gas, or a solid which is in a flowable form.
  • a universal mounting device is provided for each aerosol container, by which means it is removably connected to the gun.
  • Figure 1 is a side exterior view of a gun according to this invention, with aerosol containers connected at the top and bottom.
  • Figure 2 is a side exterior projection of a universal mounting device according to this invention, suitable for removeably connecting aerosol containers to the inventive gun. 5 - DETAILED DESCRIPTION OF THE INVENTION
  • the inventive device has the advantages of finely adjustable metering of the dispensed product, simpli- city of design, satisfactory protection of the dispensed substance from ambient conditions prior to dispensing, and simplicity of cleaning.
  • coraponent flowable substances 5 of a chemical nature, for example Polyurethane liquids and foams, epoxy resins, polyesters, silicones, metal or wood-filled resins including epoxies, methyl methacrylates, and the li e. .
  • Limitations on the substances to be dispensed are determined primarily by the materials Q. of which the gun is constructed, and the hermetic tolerances of the gun. Thus, if . the gun is suf- ficiently hermetic, it can be used to . mix and dispense gases or gaseous suspensions of solids or liquids.
  • liquids, solutions, oil-in-water, or water- 5 in-oil suspensions, colloidal suspensions, creams, and the like may be dispensed.
  • Solids may be dispensed where they are in flowable form, such as silica or talc powders, either alone or in admixture with gaseous or liquid carriers.
  • any substance that can be 0 packaged in an aerosol container can be used in the inventive device.
  • the gun can be used with one or more (preferably two) aerosol containers with the same or different contents. Where the same contents are dispensed from all aerosol containers, the gun device multiplies the effective life of a single container, and permits easy and rapid replacement of one or more aerosol containers at a time. Where different aerosol contents are used, the gun device permits efficient mixing of the ingredients just prior to application, metering of the dispensing, convenient application of the mixture to a work piece, and easy and rapid changing of the flowable substances to be mixed by changing one or more of the aerosol * containers. Replacement of used containers is also facilitated.
  • Cleaning the gun can be effected quickly and easily by the insertion of a pressurized neutral or inert gas or liquid through the aerosol inlets.
  • the pressure can be afforded by a suitable gas or liquid pump, or by an aerosol container with inert or neutral contents.
  • the gun can be cleaned periodically during use, or when changing aerosol components, without taking it apart.
  • the two aerosol container-s (1) are shown projecting upward and downward from the gun frame (18). Although this is a preferred embodiment, one or more Containers may be inserted into inlets at any point around the frame, provided that the aerosol container masses are reasonably balanced or compensated.
  • Each aerosol container (1) is removably connected to the gun frame (18) by an adapter (2), which, with the aerosol nozzle, may form a male-female threaded coupling, bayonet coupling, friction-fit coupling, or the like .
  • the adapter may also be in the form of a universal mount as shown in Figure 2, which will be discussed below.
  • the adapter also opens the valve of the aerosol container, in a conventional manner.
  • each aerosol container (1) flows through a one-way (ie non-return) valve (8) into a separate receiving chamber (13) > which is flowingly connected at one end to a conduit (4).
  • a one-way (ie non-return) valve (8) into a separate receiving chamber (13) > which is flowingly connected at one end to a conduit (4).
  • the static mixer (4) is flowingly connected to a single, optionally removeable, static mixer (5), where two or more different flowable substances may be mixed.
  • the design of the static mixer (5) is conventional, and may vary depending upon the nature of the flowable substances and the degree to which they are to be mixed. Generally, the mixing itself is achieved by the size, shape, and placement of baffles within the mixer (5); preferably there are no moving parts.
  • the static mixer (5) is conventional, and may vary depending upon the nature of the flowable substances and the degree to which they are to be mixed. Generally, the mixing itself is achieved by the size, shape, and placement of baffles within the mixer (5); preferably there are no moving parts.
  • each receiving chamber (13) opposite the conduit (4) may be biased by a moveable baffle of conventional design (not shown) which is in turn biased by an actuating means such as a trigger (3).
  • the en-d of the receiving chamber (13) opposite the conduit (4) is fixed, and the trigger (3) acts to withdraw a reciprocating needle valve (not shown) located in the receiving chamber (13) at the point where the receiving chamber (13) meets the conduit (4).
  • the needle may be of such a length that it reaches to the top of the conduit (4) and closes it in this area.
  • Locking means may be attached to the trigger (3) and biased against the back of the gun , so that the trigger (3) may be pulled back against the gun handle (14) when the gun is not in use, thus preventing accidental discharge.
  • the locking means (7) is preferably in a wishbone shape with the parallel ends pivotally 6 attached to the trigger (3) and a locking screw attached to the other end.
  • An adjusting screw (15) may be present to adjust the degree to which the trigger (3) can be compressed v / hile the gun is in use, thus regulating the flow of discharge through the nozzle.
  • the frame (18) and other parts of the gun can each be constructed of metal, plastic, or a composite.
  • the static mixer (5) and outlet (6) be constructed of a suitable plastic or composite since they may be removed individually or as a unit and discarded after each use.
  • the conduits (4) may be removed in case by removing the at coupling (19) which may be a screw .. bayonet, friction, or other type of joint. This will reduce the proble of minor amounts of container contents remaining within the gun mechanis.
  • the conduits (4) and static mixer (5) may be of any configurations including cylindrical, plano-parallel, prismatic, and 'the like.
  • the static mixer (5) may also be a regular prism, cube, or sphere.
  • the universal mounting device shown in Figure 2 is a preferred embodiment of this invention, especially when combined with the gun of Figure 1.
  • the universal mount comprises a preferably planar support base (17) from which generally perpendicularly extend two diametrically outwardly bowed parallel prongs (16).
  • Slideably mounted on both prongs (16) is an aerosol container guide (10) which may be locked at any points along the prongs (16) by means of at least one rack and set-screw System (11), preferably one such System ( 11) for each prong (16).
  • a snap closure (12) is attached to the guide (10) so that when an aerosol container (1) is placed within the device, the closure (12) may be biased against the bottom end of the Con ⁇ tainer (1) so as to hold it in place.
  • the snap closure (12) should have an inverse V-shaped flange to secure the container from moving.
  • the guide (10) may be a semi-circle, and the closure (12) should bias against the bottom of the container.
  • the guide (10) may be comprised of opposed semi- circles, and the closure (12) may bias against the side and / or the bottom of the container (1).
  • the aerosol container's discharge end may be fitted into an optional mounting adapter (9) which is attached to the support base (17).
  • the mounting adapter (9) serves the same function as adapter (2) described previously, and may be of the same type.
  • the universal mounting device or components thereof, as well as any other metal parts of the gun, especially including metal adapters (2), (9), may be covered with a protective plastic film such as a nylon or polytetrafluoroethylene.
  • the inventive device is simple to use.
  • the con duits, static mixer, and outlet, if not already connected, are attached to the front of the gun.
  • One or more aerosol containers are attached to the adapters and / or the universal mount and flowingly " 'connected to tne gun.
  • the one or more aerosol Containers discharge their flowable substance into the gun, which flows from the receiving chamber through the conduits to the static mixer where multiple flowable subtances are mixed and then the flowable substance exits through the outlet .
  • the gun may then be used in a manner similar to a glue gun or caulking gun, for dispensing virtually any type of flowable chemical system including sealants, caulks, insulators, bonding agents, glues, fillers, paints, and 5 the like. With a suitable nozzle and heat-resistant materials, the gun could even be used to discharge gaseous mixtures such as oxygen and acetylene for use in spot welding. Foams such as Polyurethane can also he generated and spot applied for packaging, insu-
  • the proportions of each component may be adjusted by various means including varying the pressure of the
