Description

COLLAPSIBLE DISPENSING SYSTEM
TECHNICAL FIELD
The technical field of this invention relates to devices for the dispensing of non-solid, viscous materials BACKGROUND ART
Cartridges for storing and dispensing viscous materials such as resins, sealing compositions, dental compositions, or insulation compositions are known in the art Such cartridges generally comprise an outer casing containing at one end, an end piece which attaches to an application nozzle and at the other end, a rear thrust wall designed to slide toward the end piece and force the viscous material out of the nozzle This sliding of the rear thrust wall is brought about by a piston which is generally an integral part of a manual operating device, usually in the form of a gun equipped with a rack or friction advance mechanism
Some viscous products consist of several viscous components which must be mixed, in given proportions, only at the time of application It is known in the art to store the viscous components in multiple containers inside cartridges in such a way that the advancing rear ■thrust wall will force the components through a single mixing nozzle whereby the components become mixed at the time of application
U S Patent No 5,339,992 to Barthomeuf et al discloses a cartridge comprising an outer casing and an inner casing Each casing holds a viscous component of a final product The cartridge has a front end piece for receiving an application nozzle and a rear thrust wall which drives the components forward and through the nozzle when it is advanced
The closest prior art known to the inventor are U S Pat Nos 5,161 ,715, 5,184,757, and 5,242,082 to Giannuzzi These patents disclose a double-barreled gun designed to inject a two-component epoxy composition The gun contains two parallel barrels, each containing a foil pack containing viscous components of the final epoxy composition The gun contains two front end pieces which are adapted to send the components into a mixing nozzle The gun contains two pistons for urging the foil packs forward As the foil packs are urged forward, cutting elements in the forward end of each barrel slit the foil packs and allow for the discharge of the stored components
U S Pat No 3,767,085 to Cannon et al, U S Pat No 5,722,829 to Wilcox et al, and U S Pat No 5,875,928 to Muller et al are similar to each other in that each of these references discloses a double-barreled cartridge capable of receiving two parallel containers containing viscous materials which should be mixed only at the time of application Each container empties into a front end piece which passes the viscous components to a mixing nozzle Each container has a rear thrust wall which may be forced forward to expel the contents of the container into the front end piece Thus, cartridges and guns for these cartridges for use with viscous components which must be kept separate from each other are well known in the art One problem which exists is the incompatibility of the cartridge of one manufacturer with the gun of another manufacturer or even the gun of the same manufacturer with a different size cartridge Thus, a multiplicity of guns and cartridges are on the market, only a few of which are compatible DISCLOSURE OF INVENTION
The inventor recognized this problem and solved it by providing a cartridge which fits common caulking guns and which holds a container made up of a plurality of material chambers which hold viscous ingredients which should be kept separate until the time of application The cartridge and containers are designed for a single use, and are constructed of recyclable materials The chambers may have a variety of ratios of the several components
The cartridge contains a tubular casing, a forward end cap having an orifice capable of snugly holding a piece capable of coupling with a conventional mixing nozzle, and a rear thrust wall capable of being urged forward by the piston of a conventional caulking gun
The container is made up of multiple collapsible chambers containing closed rear ends, closed side edges, at least one edge being in common for at least a portion of the length of a side, and a forward end in which the forward edges of the chambers are sealed to a forward end piece The collapsible chambers may be sealed bags made of sturdy plastic or expandable and compressible chambers having accordion configurations Each forward end piece has a body portion, a shoulder portion, and a neck portion When in position in the cartridge, the multiple body portions of the end piece will form a circle which will abut with the cartridge, the shoulder portions will abut with the end cap, and the neck portion will snugly fit through an orifice in the end cap to engage a mixing nozzle BRIEF DESCRIPTION OF DRAWINGS

The invention will now be described in detail with reference to the above drawings Like numbers refer to like parts throughout the description
The collapsible dispensing system 2 of this invention is useful for the dispensing of viscous materials which should be kept separate until the time of application Examples of such materials are epoxy resins which contain a resin and a catalyst, sealing compositions, and insulation compositions
The system 2 is made up of a container 4 for the viscous materials and a cartridge 6 for the container 4
The container 4 comprises at least two chambers 8 and a forward end piece 10 Each chamber 8 will be filled with a viscous material which should be kept separate from the other material during storage Each chamber 8 contains a closed rear end 12, closed side edges 14, at least one of the closed side edge 14 being common with at least one other chamber 8 for at least a portion of its length, and a forward edge 16 The forward edge 16 of each chamber 8 is attached to a separate or unified forward end piece 10
The forward end piece 10 of the container 4 is a hollow body which forms a passageway 18 between the inside of the chamber 8 and a mixing nozzle (not shown) Mixing nozzles are well known in the art, and do not constitute a part of the present invention The forward end piece 10 comprises a body portion 20, a shoulder portion 22, and a neck portion 24 The body portion 20 has an arcuate peripheral edge 26 and a straight central edge 28 The shoulder portion 22 connects the body portion 20 and the neck portion 24 and forms the front end of the chamber 8 The shoulder portion 22 is bounded by an arcuate peripheral edge 30 which abuts with the arcuate peripheral edge 26 of the body portion 20, a straight central edge 32, and an arcuate central edge 34 The neck portion 24 is an elongated piece having an arcuate peripheral edge 36 which abuts with the arcuate central edge 34 of the shoulder portion 22 and a straight central edge 38 While in storage, the neck portion 24 is closed by a friction-fit or threaded closure (not shown) The neck portion 24 will attach to a conventional mixing nozzle by a friction fit or by threads 40 While the several portions have been described separately, it is preferable that the forward end piece 10 be manufactured as a single unit
The body portion 20, shoulder portion 22, and neck portion 24 are shaped such that when a plurality of forward end pieces 10 are fitted together, the arcuate peripheral edges 26 30 36 form circles and the straight central edges 28 32 38 fit snugly together Thus, if the container 4 is made up of two chambers 8, and therefore has two forward end pieces 10, each body portion 20 will take the form of a semi-circle when viewed endwise When placed into the cartridge 6, each straight central edge 28 32 38 fits flat against the straight central edge 28 32 38 of the other and the outer configuration forms a circle If the container 4 is made up of three chambers 8, and therefore has three forward end pieces 10, each body portion 20 will take the form of a third of a circle (120°) when viewed endwise When placed into the cartridge 6, each straight edge 28 32 38 will fit snugly with the others
The containers 4 must be air-tight, collapsible, and made of material which economically justifies disposal and recycling of the system 2 following use
One form of chamber 8 is made of sturdy flexible material, such as plastic or rubber, and is in the form of a closed bag 42 The chamber 8 has a closed rearward end 12, at least one closed side edge 14, at least one closed side edge 14 being in common with at least one other chamber 8 for at least a portion of its length, and the forward edge 16 of the chamber 8 is connected to the forward end piece 10 The chambers 8 may be manufactured using conventional means for making plastic bags, but including the additional step of joining at least two such chambers 8 together with a heat seal or chemical bonding agents The chambers 8 may be joined throughout their entire length or for some other desired shorter distance Heat seals are preferred, but conventional chemical bonding agents are acceptable for the purpose of creating closures between the chambers 8 The end pieces 10 are preferably made of one- piece molded plastic
Another form of chamber 8 according to this invention is made up of sturdy, shape- retaining, but flexible material, such as plastic or rubber and has an accordion configuration 44 The chamber 8 has a closed rearward end 12, a body 46 having circumferential peaks 48 and valleys 50, at least one side edge 14 in common with, or slightly separated from, at least one other chamber 8, and the forward edge 16 of the chamber 8 is connected to the forward end piece 10 The chambers 8 may be manufactured using conventional means for making collapsible plastic or rubber bottles, but including the additional step of joining at least two such chambers 8 together with a heat seal or chemical bonding agents The chambers 8 may be joined throughout their entire length or for some other desired shorter distance As the end piece 10 is required to be firm and unyielding and the body of the chamber must be flexible, it is not recommended that the body of the chamber 8 and the end piece 10 be manufactured of the same material As above, the end piece 10 is preferably manufactured of one piece molded plastic
Chambers 8 having the same or different volumes may be supplied in a single container 4 Thus, when 1 1 ratios of materials are desired for a two-chamber container 4, each chamber 8 is of the same length and has the same cross-sectional area Where ratios other than 1 1 are desired, such as 2 1, 5 1, or 10 1 for two-chambered containers, the length of the chambers 8 remains the same, an 1 the cross-sectional areas are adjusted to provide the desired volumes The same principle applies for three or more chambers 8 This enables the user to select a single container 4 for procedures requiring one ratio of materials and another single container 4 for another procedure requiring a different ratio of materials Thus, unlike the prior art containers, a single cartridge 6 and a single gun (not shown) will be suitable for all containers 4 regardless of the ratio of materials required by the procedure If only a portion of the material is used, the neck portion 24 of the forward end piece 10 may be closed with a threaded or friction-fit closure (not shown), thus preventing the materials from being exposed to air
The system 2 is designed for one-time use Therefore the cartridge 6, forward end cap 52 and rear thrust wall 54 are made of recyclable materials The tubular cartridge 6 may be made of metal, cardboard, or sturdy shape-holding plastic The forward end cap 52 is preferably made of flexible rubber or plastic so as to achieve easy application to, and removal from the cartridge 6 The forward end cap 52 contains a centrally located circular orifice 56 which provides for a snug fit with the neck 24 of the forward end pieces 10 of the container 4 The rear thrust wall 54, which preferably contains a forward extension 58, is preferably made of metal or plastic The size of the rear thrust wall 54 allows easy sliding within the tubular cartridge 6
The chambers 8 may be filled with the viscous materials by forcing the viscous material under pressure into the proper chambers through the forward end pieces 10
In use, the container 4 comprising a plurality of filled chambers 8 is placed into the cartridge 6 and the assembled system 2 is placed into a conventional caulking gun The rear thrust wall 54 is impelled forwardly, causing the viscous materials in each of the chambers 8 to be expelled through the necks 24 of the front end pieces 10 to be mixed in the mixing nozzles The materials will be expelled in direct ratio to the volumes of the chambers 8 Thus, the required, pre-selected ratios are available to the user INDUSTRIAL APPLICABILITY
A system for dispensing viscous materials which should not be mixed until the time of application is made up of a cartridge and a container which fits into the cartridge The cartridge fits into conventional caulking guns, thus eliminating the need for multiple, unique guns The cartridge is simple in nature, containing a rear thrust wall which slides forward when impelled by the piston of a gun, and a forward end wall containing a central orifice The container is made up of a plurality of collapsible chambers for holding the viscous materials The chambers may be in the form of sealed collapsible bags or may have an accordion configuration The chambers may be of any predetermined volume ratio As the rear thrust wall is impelled forwardly, the chambers holding the separate viscous materials collapse and the viscous materials are forced through forward end pieces The forward end pieces are formed such that when fitted together, they fit together snugly and form a circle as their outer configuration. The forward end pieces contain necks which carry the still-separated viscous materials to a mixing nozzle for mixing and application to the desired site.
