INVENTOR HUGH W. CAMPBELL HIS ATTORNEYS ADHESIVE AND SEALANT DISPENSER WITH GRINDING MEANS BACKGROUND OF THE INVENTION In the art of adhesive and sealant systems that consist primarily of a base material and a catalyst compound, twopart mixtures of this type have been on the market and have been used in the industry for a number of years, In the case of adhesives, there are known epoxy systems that are produced by cross-linking certain materials or by curing one or more materials with the aid of an activator or a catalyst; however, these systems have not enjoyed a popular place in the market because of the difficulty in controlling the exact quantities to be mixed and also the difficulty in mixing the base material and the catalyst. For example, an epoxy system that is cured with a diamine-type'catalyst may be mixed in a ratio of l2 parts base material to one'part catalyst, so it is seen that such a system is not practical for ordinary household use because of the inability or, at least, the difficulty encountered in weighing and measuring the exact quantities of the base material and the catalyst compound.

A number of systems also introduced on the market utilize premixed or prepackaged volume ratios and hence do not require weight or volume figuring or measurement on the part of the user. This type of packaging is deemedsatisfactory from the mixing point of view, but it often results in considerable waste, because the unused parts of the mixed systems cure into an unusable mass. Likewise, several approaches to stoichiometric mixing of minute quantities of the ingredients have been developed by various adhesive manufacturers.

In the case of sealants, there are the known cartridge types that comprise a mixture or a solution of the two-part systems; however, these cartridges are basically manufactured for mixing a given quantity of the ingredients and also are not rechargeable or reusable. Additionally, the cartridges are generally adapted for use only in a total liquid or flowable system.

A review of the prior-art shows devices such as a storage and mixing cartridge having separate forward and rear compartments for the ingredients provided by a partition, the forward compartment containing the catalyst or accelerator, and the rear compartment containing the base material, such as a resin. A dome-shaped apertured plunger or dasher element is slidably moved to mix the materials, and the partition and the plunger constitute a seal between the compartments in one position of the parts, all as seen in U.S. Pat. No. 3,l64,303, issued Jan. 5, 1965, on the application of Herbert L. Trautmann. Another example of the prior art is that shown in U.S. Pat. No. 3,348,546, issued Oct. 24, l967, on the application of Ralph R. Roberts and Boris Schwartz, where an intermixing syringe includes a housing with a plunger slidable therein, the plunger having a piston portion with two or more sealing surfaces and one or more storage chambers. Such syringe device, know as a disposable type, is adapted for the storage, transfer, and mixing of prepackaged ingredients. The forward chamber contains a dry material, and a flowable or liquid material, carried in a chamber in the movable plunger, is introduced into the dry the chamber to be mixed. I

Although the prior art shows these various devices for storing, mixing, and dispensing the mixed materials, these devices do not provide means for mixing and dispensing materials wherein one or more of the ingredients are in an isolated state.

SUMMARY OF THE INVENTION The present invention relates to a device for mixing and dispensing adhesive and/or sealants, and, more particularly, to a unit which, in effect, breaks up one of the materials for mixing with another material and then dispenses the mixture in the desired amounts. The assembly includes a cylindrical container, an end cap and a nozzle cap on the container, a mixing head, and a charging plunger for metering the flow of the materials into position for mixing. The plunger has a plurality of spaced ports to control passage of the material through like ports in one end of the container, the material passing through the ports being regulatedby rotation of one set of ports in relation to the other. The mixing head is carried on a shaft extending through the container and includes a handle on one end of the shaft for turning the mixing head. Additionally, the head is cone-shaped and has a roughened or knurled surface, and employs auger-type grooves to feed the material from the container onto the surface of the head. The nozzle cap is of funnel-shaped construction which locks on one end of the container, and which has an inner roughened or knurled surface, complementarily positioned, but of slightly different taper from that of the mixing head surface.

This particular construction provides for the storage, mixing, and dispensing of a two-part material system, one part of which is inhibited or isolated from the other by reason of being enclosed in capsular or encapsulated form. The base material is generally selected as the ingredient in the encapsulated state, and, as it is being fed into the nozzle cap portion of the device, the action of the roughened cap and head surfaces ruptures and grinds this material into a state adaptable for mixing with the catalyst material. A coil spring is wrapped around the stem of the charging plunger between the plunger plate and the cylinder end cap to exert sufficient pressure to force the base material capsules and the other ingredient through the ports, into the auger grooves, and into the roughened surface of mixing head. The amount of mixed material is more easily controlled by use. of the capsular product, and the user is free to mix only the desired proportions.

While the use of the base material in capsular form and the catalytic material in a liquid or flowable state is the preferred method of storing these materials, the invention is also applicable in cases where both materials are encapsulated. In the liquid-capsular method, the materials may be stored separately and then mixed in the dispenser when ready for use, or the capsules may be stored by suspension in the liquid prior to use and the desired amount then placed in the cylinder. In the capsule-capsule method, if both capsular materials are stored separately, the desired amounts of each may be thoroughly mixed in a separate container and the mixture of capsules placed into the cylinder, or the separate ingredients could be placed into the cylinder and thoroughly mixed therein prior to the grinding action, which then ruptures the capsules and mixes the materials for use. In the case of a separate container with a mixture of the capsules, such container may assume the form of a cartridge readily insertable into the cylinder, whereby the plunger forces the mixture through the cylinder ports and onto the grinding surface of the head.

In view of the above discussion, the principal object of the present invention is to provide a mixing and dispensing device which includes complementary surfaces for preparing an isolated-form material into a state for mixing with another material.

A further object of the present invention is to provide a device capable of rupturing the isolated material and simultaneously mixing this changed-state material with another material.

An additional object of the the present invention is to provide a device having selective control means for metering and for mixing the desired amount of isolated and nonisolated materials.

A still further object of the present invention is to provide a mixing head and a nozzle cap for a dispenser, the head and the cap having roughened surfaces for rupturing encapsulated material and for mixing this material with a second material.

Additional advantages and features of the present invention will become clearly understood from a reading of the following description taken together with the annexed drawings, in which:

FIG. 4, on the sheet with FIGS. 2, 3, and 8, is a sectional view taken on the line 4-4 of FIG. 3;

FIG. 5 is an end view of the mixing head portion of the dispensing device showing the knurled surface thereon, the view being taken on the line 5-5 of FIG. 1;

FIG. 6 is a view in perspective of a modification showing a cartridge-type refill unit, containing intermixed encapsulated materials, for placing within the cylinder;

' FIG. 7 is a sectional view similar to FIG. 2 but showing the dispensing device with the cartridge unit of FIG. 6 installed within the cylinder; and

FIG. 8 is a modified form of the nozzle tip for the dispenser unit.

Referring to FIGS. 1 and 2 of the drawings, the dispenser unit includes a cylinder 10 open at one end thereof for reception ofa piston or plunger 12 and the dispensing ingredients or like material 13, the plunger having connected thereto a ho]- low stem 14 of a length greater than that of the cylinder, and the stem having a knurled portion 15 at its free end. The other end of the cylinder 10 has a closed wall portion 16 with a bore 18 therethrough for receiving a shaft 20, the shaft extending slidingly through the hollow stem 14 and having a handle 21 attached at one end thereof for turning said shaft. An end cap 22 having a bore 23 sufficiently large for receiving the stem 14 is suitably formed for placement on the open end of the cylinder 10 to contain the material 13 placed therein. The cylinder 10 includes four lugs 24 equally spaced on the exterior surface of its open end for mating with recesses 25 in the end cap 22 and for securing the cap in locking fashion when engaged therewithin. Additionally, grips in the form oflugs 26 are formed on the periphery ofthe end cap 22 for the purpose of aiding in twisting action when the cap is being locked and unlocked.

The wall portion 16 of the cylinder 10 has a series of circularly aligned and equally spaced holes or ports 27 therein, as best shown in FIG. 5, the ports being positioned to cooperate with companion ports in the plunger 12. FIGS. 3 and 4 show the construction of the plunger, generally designated as' 12, which includes a disc 28 secured to and integral with one end of the stem 14. A plate 29, consisting of two halves 3t) and 31 held together by pins 32, captures the disc 28 while allowing it to rotate with the stem 14. The disc 28 has holes or ports 33 therethrough, and the plate 29 has holes or ports 34 on the same circular line as those ofthe disc.

As seen in FIG. 4, the plate 29 has a lip portion 35 cooperable with a reduced-diameter portion 36 ofthe disc 28 to retain the disc in position but allow the disc to rotate in relation to the lip portion and the plate. The lip portion 35 has two cu touts 37 and 38 (FIG. 3), which serve as stops for a pair oflugs 39 and 40 on the disc. In this respect, the rotation of the disc 28, by reason ofturning the stem 14 in relation to the plate 29, is limited for the purpose of either aligning the ports33 with the ports 34 in an open position of the plunger or misaligning the ports to a closed position thereof. It is through alignment of these respective ports in relation to each other that the material is metered into the cylinder space beyond the plunger 12 and onto the mixing head. The plate 29 also has, on its periphery, a pair of nibs 41 and 42, which move along guideways 43 and 44 (see FIG. 2) onthe interior diameter of the cylinder 10. The nibs are slidable along the guideways as the plunger is reciprocably moved in the cylinder, but the nibs prevent rotation of the plate 29 in relation to the disc. In this way, the plate is angularly fixed in position within the cylinder. A spring 45 is placed on the stem 14 to urge the plunger 12 along the cylinder 10, the spring being captured between the plunger and the end cap 22.

Referring to FIG. 3, the cutout 37 is bounded by surfaces 46 and 47, and the cutout 38 is bounded by surfaces 48 and 49,

which surfaces act as limits of rotation for the lugs 39 and 40. The disc 28 is shown in its counterclockwise position, the lug 39 engaging the surface 46 and the lug 40 engaging the surface 48, wherein the ports 33 and 34 are not aligned, and therefore blocks flow of any material from the space nearest the end cap 22 (or the rear end of the cylinder) to the space in front ofthe plunger. When the stem 14 is turned clockwise, as viewed in FIG. 3, the disc 28 likewise turns clockwise, and its ports 33 are then aligned with ports 34 in the plate 29 to allow flow of material 13 into the space ahead of the plunger (see FIG, 2).

The shaft 20 has a mixing head-S0, shown in FIGS. 1, 2, and 5, fixed to the end distal the handle 21, the head presenting a flat surface 51 against the cylinder end wall portion 16 when the device is assembled. The circumferential portion of the mixing head 50 has an auger arrangement 52 formed thereon to move material, coming through the ports 27 from the space adjacent the surface 51, to a sloping head surface 53. The head surface 53 is roughened or knurled to provide a grinding surface for material passing from the cylinder 10 to the dispensing nozzle cap 54. The nozzle cap 54 likewise has a roughened or knurled surface 55 (see also FIG. 8), mating or cooperating with the surface 53 for the purpose of grinding and mixing the material being metered through the ports from the cylinder 10. The head 50 has a central dispensing guide 56 secured thereto and extending into the nozzle 57 of the cap 54. This guide may further mix the materials and direct the mixture evenly through the nozzle.

FIG. 6 shows a cartridge-type refill unit 60, which is formed to slide in to the cylinder 10 ahead of the plunger 12, the cartridge containing materials for being dispensed from one end thereof by reason of movement of the plunger, through the ports 27 in the cylinder end wall portion 16, along the auger 52 grooves, and onto the roughened surfaces 53, 55 to be mixed for dispensing. The refill unit 60, ofcourse, conforms in shape with the interior of the cylinder, the guideways 43 and 44 (FIG. 2) accommodating the nibs on the unit. The material 13 is contained within the cartridge by a frangible cover 61 at each end thereof, the removal of which cover 61 exposes a central tube 62. As shown in FIG. 7, the tube 62 slides over the shaft 20, and the stem 14 of the plunger 12 slides over the tube 62. In this respect, the showing of FIG. 7 calls for a smaller-diameter plunger 12 to fit inside the cylinder 10, and for a larger-diameter plunger stem 14 to slide over the tube 62.

FIG. 8 shows a modification in the nozzle portion of the dispensing device, which is removable from the cap 54. In place ofthe nozzle 57 (FIGS. 1 and 2)v being an integral part of the cap 54, the cap is constructed with an opening 65 in its end for insertion of the removable nozzle 66. The nozzle 66 may, of course, be made ofa material ofthe throw-away type.

In the operation of the dispenser, the end cap 22 is removed from the cylinder 10 by being turned counterclockwise as viewed from the handle end of the shaft 20. As mentioned above, the cap includes recesses 25 mating with lugs 24 on the exterior of the cylinder end for securing the two parts, and the cap has grips 26 on its circumference to facilitate cap on and off" by a simple twisting action. The other end of the cylinder has similar lugs 70 matingwith recesses 71 in the nozzle cap 54. The cap 54, of course, also has grips 72 on its circumference to facilitate the twisting action for assembly or disassembly of the nozzle cap and the cylinder.

In the preferred embodiment, the base material, in a capsular or encapsulated form, is suspended in a catalytic material in flowable or liquid form, so that a quantity of the ingredients 13 is premixed and ready to be placed into the dispenser. The plunger 12 is inserted into the cylinder 10, with the disc 28 and the plate 29 in the closed position, with their ports 33, 34 misaligned, whereafter the'desired amount of the mixture 13 is placed within the cylinder, the spring 45 is placed over the stem 14, and the end cap 22 is secured. When it is desired to use a given quantity of adhesive or sealant, the stem 14 is hand-turned counterclockwise (by use of the knurled portion 15) to align the ports 34 in the plate 29 with the ports 33 in the rotatable disc 28, so that the material 13 can move into the space ahead or in front of the plunger. The plunger 12 is then pulled in the direction of the handle 21, and the material is caused to flow through the ports 34 and 33 into the space adjacent the mixing head 50 at the front of the cylinder. With the desired amount of material moved into this space (this being accomplished by withdrawing the plunger 12 to a suitable marking or graduation on the transparent cylinder wall, as seen in HO. 1), the stem 14 is rotated clockwise to close the ports 33, 34 in the plunger. The spring 45 exerts a pressure on the plunger 12 to force the material 13 through the cylinder end wall ports 27 and into the auger grooves 52.,The handle 21 is then turned to rotate the mixing head 50, whereupon the material is augered onto the surface 53 of the head, and the surface of the head and the companion surface 55 of the nozzle crush the capsules or free the isolated material to join with the other ingredient to be dispensed through the nozzle 57.

Ofcourse, if it is desired to use only a small amount of adhesive or sealant, the plunger 12 can be removed and the material placed adjacent the wall portion 16, the cylinder graduations being used to measure the desired amount. The inserted plunger then forces the material through the ports 27 and onto the mixing head.

In the case of two encapsulated ingredients placed in the cylinder, the ports in the plate 29 and the disc 28 may beused to thoroughly mix the ingredients by manual reciprocation of the plunger 12 in the cylinder. The mixed ingredients are then moved via the ports 27 in the cylinder end wall portion 16 and along the auger to the grinding surfaces, to be crushed for subsequent dispensing through the nozzle.

When a cartridge of encapsulated material is available and desired to be used, the plunger 12 is removed from the cylinder 10, the one end of the cartridge 60 is removed by tearing off the frangible cover 61, and, with the dispenser held in the nozzle-upward position, the open end of the cartridge is placed within the cylinder. The dispenser is then turned so that the nozzle is pointed downwardly, and the other end cover of the cartridge is removed. The plunger is then installed withthe ports 33 and 34 in the closed position, whereby the spring 45 forces the material 13 through the cylinder ports 27 and onto the surface of the head 50, where the material is crushed and mixed prior to being dispensed through the nozzle.

As shown in the drawings, the dispenser makeup is of a plastic type, and the only metallic part used in the construction of the dispenser is the spring 45. A butadiene-styrene composition may be used for the permanent-type device, whereas polyethylene material may be used for the throwaway parts.

It is thus seen that herein shown and described is an adhesive and sealant dispensing device which accomplishes all the objects and features of the invention. While specific modifications of the preferred embodiment are disclosed, variationson these may, of course, occur to those skilled in the art, so it is contemplated that all such variations are within the scope of the invention.
