PUTTY MIXING CONTAINER FOR CAULKING GUN-TYPE DISPENSER BACKGROUND OF THE INVENTION Putty materials in recent years have been developed which require storage and shipment in special containers. For example, epoxy putty and a catalyst for the putty are separately stored and shipped and are mixed just prior to use, and the putty sets-up rather rapidly after mixing with the catalyst. Other examples of base materials and an admix include foods and cementitious materials.

The separate mixing of putty and a catalyst in a mixing receptacle and charging a dispenser or gun with the catalysed putty is time consuming and annoying. Cleaning of the dispenser or gun is also difficult and time consuming, so that disposable containers have evolved which are adapted to be employed with a piston-type dispenser or gun which has a trigger operated shiftable plunger adapted to move progressively into the container tube to displace the putty from the tube through an outlet adapted to facilitate application of the putty. Mixing of the putty and the catalyst has nevertheless continued to pose problems, notwithstanding efforts to provide a practical combined mixing and dispensing apparatus or device.

SUMMARY OF THE INVENTION The present invention is directed towards solving the problems inherent in the use of catalysed vputty materials which are shipped and stored separately from a catalyst and mixed with the catalyst at the time and at the place of use of the putty.

More particularly, the present invention involves the provision of a combined mixer and disposable container having separated quantities of putty, or other plastic, and a catalyst, or other additive for the plastic material. In accomplishing the foregoing, a typical tubular container may be employed, having an outlet fitting to facilitate application of the dispensed, mixed plastic, or putty, such container being adapted for use in a conventional gun or trigger actuated piston device,

the tube having the mixer disposed therein, together with a suitable quantity of the putty or un-catalyzed plastic, and the catalyst also being contained in the tube, but separated from the putty or base plastic by a removable barrier, such as a bag or divider. When the barrier is removed, the mixer is operated to mix the base putty or plastic with the catalyst, and thereafter, the mixed material is ready to be dispensed.

The mixer, according to the invention, may be then removed from the tube prior to assembly of the tube of mixed plastic or putty with the gun, or the mixer may be constructed so as to remain in the tube and to be progressively deformed or disintegrated during displacement of the mixed plastic or putty from the tube by the gun. In the latter case, separatedisposal of the mixer is avoided.

This invention possesses many other advantages, and has other purposes which may be made more clearly apparent from a consideration of forms in which it may be embodied. These forms are shown in the drawingsaccompanying and forming part of the present specification. They will now be described in detail, for the purof illustrating the general principles of the invention; but it is to be understood that such detailed descriptions are not to be taken in a limiting sense, since the scope of the invention is best defined by the appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring first to FIG. 1, there is shown a typical putty or plastic gun G adapted to accommodate a disposable tube or container C of putty or other plastic material, such as a mixture of base epoxy putty and. a catalyst, or other base material and admix, such as foods, cementitious mixtures, and the like. The plastic or putty P is adapted to be displaced from an applicator tip or outlet 10 by a piston or follower 11 which is shiftable axially in the tubular container C by a ratchet rod 12, the rod being shiftable from the retracted position, shown in broken lines in FIG. 1, at which the container is assembled with the gun, progressively inwardly, by a trigger or feed pawl 13 which is pivotally mounted at 14 on a hand grip 15. Generally, the piston or follower 11, in such guns, is composed of a disposable cup, as is well known, whereby, following use of the plastic or putty P, the container C, its outlet 10, and the. cup or piston 11 may be discarded, without requiring clearing of any of the components of the gun. Such guns need no further description herein, but are more particularly shown and described in Letters Patent of the United States, No. 3,l89,226, granted June 15, 1965. 1

The present invention is directed to the problems inherent in packaging, storing, shipping and using tubes or containers, as indicated at C, whereby, the base plastic or putty or other base material and a catalyst or other admix are separately contained in the container, are mixable at the time of use, and the components of the combined mixer and container may be conveniently disposed of following use of the plastic putty or other mixed material from the container.

Referring to FIGS. 2 through 5, one embodiment of the combined container and mixer is illustrated. In this form, the container C is seen to comprise a tubular, elongated body having an end 16 provided with a suitable outlet piece or tip 17 having an outlet passage 18 and the usual bevelled end 19 to facilitate application of plastic or putty to a work area. The container may be composed of inexpensive material such as cardboard, and the tip 17 may be composed of suitable plastic material molded to provide an internal shoulder 20 engageable internally of the end wall 16 to retain the tip 17 in assembly with the container C. Similar containers are well known for use with guns of the type described above.

In the embodiment now being described, the container C has an end closure 21 at the opposite end from the tip 17. Unlike the usual closure, the closure 21 is slotted at 22 and has a body section 23 which secures the closure in the end of the container C, as by a tight fit.

Disposed within the container is a mixer means, in the present embodiment, in the form of an elongated, blade-like plate or stirrer 24 having perforations 25 therein, with the perforations preferably arranged in alternating or staggered relation, as shown in FIG. 2. At its inner end, the mixer plate 24 is rotatably supported on a bearing 26 which also forms a valve and is affixed to the plate 24 by means of a tongue 27 extending into a notch in the bearing 26. The bearing 26 rotatably engages the inner end 20 of the tip 17 and closes the opening or passage 18. For further protection, a plastic cap may be inserted over the tip 17, for closing off the tip. The outer end of the mixer plate 24 extends outwardly from the container C through the slot 22 in the closure 21 to provide an end portion 28 adapted to be rotated to cause rotation of the mixer 24. Thus, the end 28 has a tool-receiving opening 28a into which a rod, screwdriver or the like (not shown) may be inserted to provide a handle to facilitate manual rotation of the mixer 24.

A quantity of base plastic, putty or other material 29 may be placed into the container at one side of the mixer 24, as seen in FIGS. 4 and 5, and a quantity of catalyst or other admix 30 may be placed in the container at the other side of the mixer 24, and barrier means is employed to isolate the base material from the catalyst. In the illustrative embodiment, the barrier means is in the form ofa flexible, plastic, tubular receptacle 31 composed of a strip of tubular plastic material cut to provide a length greater than the length of the container C, so that an end 32 of the strip 31 may be turned back on the strip 31 to effectively provide a leak-proof closure for the admix 30, which closure is automatically openable when mixing of the base plastic or putty and the catalyst is desired. The other end 33 of the barrier means or tubular strip 31 extends from the container, through the slot 22 in the closure 21, to provide a portion adapted to be manually grasped. To discharge the catalyst 30 from the end 32 ofthe tubular strip 31, it is only necessary to manually grasp the end 33 and pull outwardly on the strip, so that the end 32 is progressively released from engagement between the mixer 24 and the adjacent portion of the catalyst containing strip 31, and ultimately the catalyst is discharged from the end 32, as the tubular barrier means is stripped outwardly through the slot 22 in the closure 21. Discharge of substantially the entire quantity of the catalyst is assured by the stripping action applied to the tubular strip 31.

After removal of the barrier means or tubular strip receptacle 31, the mixer is rotated, and the previously isolated base material 29 and the additive 30 may be mixed thoroughly by rotation of the mixer 24. Following the mixing of the materials, the mixer 24 is pulled outwardly in the closure slot 22 to strip the mixed material from the mixer and open the outlet passage 18, as the bearing 26 moves away from the tip 17. When the bearing 26 contacts the closure 21, the closure is removed from the container, and a disposable cup or piston is inserted in the end of the container C, so that the container is then in readiness for use in a gun, as shown in FIG. 1 and previously described, which has a dispensing plunger engageable with the piston or cup to cause the mixed material to be dispensed from the container C, as desired. Thereafter, the container C may be disposed of.

From the foregoing, it will be apparent that the invention provides a convenient container or package for both a base material and an admix material, such as a base epoxy putty and a catalyst, whereby the two materials are shipped or stored together until the materials are to be mixed and used.

Another embodiment of the invention is illustrated in FIG. 6, which also has the advantages of the embodiment described above, but which differs from the latter in that the mixer need not be removed from the container and disposed of separately. Instead, in the modified construction, the mixer remains in the container and is simply deformed, and if desired, fragmented, during dispensing of the mixed material, as the plunger or piston 11 progressively moves inwardly in the container to displace the mixed material from the container.

More specifically, in the modified construction, the mixer plate or stirrer is designated 124 and has openings or holes 125 spaced longitudinally thereof. The mixer 124 further is so constructed as to be axially deformable in response to edwise compression, and thus, in the illustrative form, the mixer 124 has transverse corrugations or undulations which, while having a tendency to collapse upon application of an endwise force to the mixer, serve to resist bending of the mixer plate during rotation of the latter as the materials are being mixed. A type of plastic material or other mixer configuration may be used that has excellent strength in bending or twisting yet is brittle upon endwise pressure, and may break into fragments or pieces, in lieu of collasping. In this embodiment, moreover, the end 128 of the mixer 124 is shown as terminating within the slot 122 in the end closure 121, so as to illustrate that the mixing means may be rotated by rotating the closure 121 relative to the container C.

As in the previously described embodiment, a strip type, tubular receptacle 131 is employed to isolate the catalyst from the base putty material, the strip receptacle 131 having its end portion 132 turned back so as to be sealingly compressed against the mixer 124. The outer end 133 of the tubular strip 131, as in the previously described embodiment, extends through the closure slot 122 so as to be manually grasped to enable stripping of the catalyst from the receptacle 131 as the receptacle is pulled through the slot.

Since the mixer 124 is to remain in the container C and be deformed therein during use, the mixer 124 is not provided with a valve means corresponding to the member 26 of the first described embodiment, normally blocking the outlet 118 in the tip 117. Instead, the inner end of the mixer 124 may ride on the flange portion 120 of the tip 117 and a closure plug 126 may be installed in the tip 117 in such a manner as to be displaced therefrom when dispensing of the mixed material is initiated, or the usual foil seal may be employed, if desired.

Referring to FIGS. 7 through 9, a modified container and mixer embodying the invention is shown, the container being designated at C and the mixer being designated at 224. v

In this embodiment, the mixer or stirrer 224, as in the previously described embodiments, has openings 225, and the barrier means includes an edge sealing portion 231a provided on the edge of the mixer 224 and a removable barrier strip 231b engaged with the mixer 224 along one side thereof to prevent inter-mixing of the base and admix materials through the openings 225, until the barrier strip 23112 is removed.

More particularly, the mixer 224 is, in this embodiment, a laminated structure, comprising outer rigid mixer elements 224a, 2241), and an intermediate flexible layer 2240, united together so that the edge portions of the layer 2240 project outwardly into sealing engagement with the walls of the container C to provide the barrier portions 231a. The barrier strip 2311) may be any suitable plastic or other material of sufficient tensile strength as to permit the end portion 233 thereof to be grasped to pull the barrier strip from the container C, and the strip 231b may be sealingly engaged with the mixer bypressure contact, by light ad-' hesive, or otherwise, to prevent leakage through the openings 225, but enabling reasonable ease of removal of the barrier strip.

To prevent leakage around the inner end of the mixer 224, this end of the mixer is shaped to substantially conform to the bearing and seal 226, as seen at 224d and 224e in FIG. 7, and the barrier portion 231a of the layer 224e of the mixer is correspondingly shaped. In the latter connection, it will be understood that the barrier means is not subjected to differential pressure during storage, but preferably, the barrier edge portion 231 will exert a wiping action during mixing to avoid residual films of unmixed materials in the container C.

As also seen in FIGS. 7, 8 and 9, the end closure 221 in this embodiment, is of modified construction, and is otherwise capable of being used in conjunction with the previously described mixers and containers of FIGS. 2 through 6.

More particularly, the closure 221 is adapted to form the piston means for displacing the mixed material from the container C when the container is assembled in the gun of FIG. I, so that it is not necessary to employ a separate piston 11.

The end closure 221 comprises an outer ring 221a adapted to abut with the end of the container C and a central portion comprising a pair of substantially semicircular segments 221b and 221c which are joined to the ring 221a by a frangible connection at 221d and which closely fit within the container C. The slot 222 is defined between the segments 22lb and 2210, and the mixer 224 and the end 233 of the barrier film 2311) extends outwardly through the slot 222. Within the container C, each of the segments 221k and 2210, respectively, has an outer peripheral sealing lip 221e, for sealing contact with the inside of the container C, and an inner sealing lip 2211f sealingly engageable with the mixer 224 and the barrier slide 2311b.

The closure 221 is also shown as having means for preventing inadvertent removal of the closure, say, during removal of the barrier strip 231b, and similar retaining means may also be employed in the other embodiments of the invention. More particularly, the cap segments 221b and 2210 are provided with external ribs 221g extending circumferentially and having inner sloped surfaces and outer surfaces substantially normal to the axis of the cap so as to bite into the cardboard container C. However, the sloping surfaces of the ribs 221g facilitate the movement of the closure segments into the container as described below.

Upon removal of the barrier slide 2311; before mixing and removal of the mixer 224 from the container C through the slot 222 after mixing the contents, excess material is wiped from the barrier and the mixer. Thereafter, the container, with closure 221 in place, may be combined with the gun of FIG. 1, and actuation of the plunger into engagement with the closure segments 221k and 2210 will force the latter inwardly, breaking the frangible connection 221d. The sealing lips 22le on the closure segments 22 lb and 221c will be forced by pressure of the mixed material into mutually contacting, sealing relation, and the outer sealing lips will be forced into sealing engagement with the inside wall of the container C, whereby loss of mixed material past the closure as it is progressively forced into the container C is minimized. Thus, with such a construction the necessity for a separate piston element, such as the piston element 11, is avoided, and use of the package is simplified.

Aother manner of providing the piston 11, while at the same time providing an advantageous cap for the container C, is shown in FIGS. 10 and 11, wherein the mixer 24 and end closure 21 are like those in FIGS. 2 through 6, and require no further description.

In this embodiment, a cap 300 is provided having a skirt 301 engageable with the end of the container C, as by a friction fit, or otherwise as desired. A cylindrical center portion 302 in the form of a piston, such as the piston 11, is connected to the skirt 301 by a frangible web 303. This piston portion 302 is adapted to fit I within the tube or container C, as shown in FIG. 11,

when the cap 300 is removed and inverted, so that upon assembly of the container C in the gun of FIG. 1, the plunger will force the piston portion 302 inwardly, to displace mixed material from the container, as previously described. Initial operation of the gun will cause the skirt portion to be broken from the piston portion at the frangible connection 303. Thus, the structure of FIGS. 10 and 11 is easy to use, and the end closure for the container and the mixing and barrier means are protected by a cap.
