Description
~9~33 THE FIELD OF THE INVENTION
~ . . .
This invention relates to packaging means for sealants or adhesives which can react with atmospheric moisture.
DESCRIPTION OF THE PRIOR ART
Sealants or adhesives reactive with atmospheric moisture present packaging and storage problems~ Essentially, such sealants must be packaged and stored in hermetically sealed containers until use and when used, all or substantially all of the aealant retained in the hermetically sealed container should be used. Otherwise, unused portions of sealant can react with atmospheric moisture and be wasted. Packaging and storage ` ~ of sealants reactive with moisture are therefore particularly c omplicated when ~such sealants are intended for delivery to customers who use or require only relatively small quantities :
15 ~ of sealant. Such customers would prefer to purchase apportioned quanhties of such ~sealsnts which sre compatable and consistent r with their use requirements of sealant to reduce waste of unused ~ .
sealants. ~ ~
.
~ :
.
~9~33 Apportioned quantities of sealants reactive with atmospheric moisture have been available to the art in the form of tubular shaped cartridges containing up to a liter of sealant. These cartridges are designed for use with a sealant gun such as a caulking gun or the like. When so used, sealant is discharged S from the cartridge through a nozzle by pressure exerted on a piston-like memher providing a moveable or slideable end or end portion of the cartridge closely fitted within the tubular walls of the cartridge.
This piston-like member requ;res undesirable design features to provide a close precision fit between peripheral portions of the piston-like member and the cartridge walls.
Oftentimes specialized seals together with drying agents are used to protect the sealant from atmospheric moisture during storage and/or during discharge of the sealant from the cartridge.
Moreover, the cartridges usually have relatively thick walls and are fabricated of hard polymeric materials and in terms of their volume and composition are difficult to dispose of from an environmental standpoint. In any event, the cost of the cartridge materials coupled with the precision requirements involved ;~ 20 in their manufacture increase the cost of sealants provided inrelatively small apportioned quantities. ~ccordingly, there is a need in the art for a relatively simple, uncomplicated and inexpensive packaging means for effectively protecting one or more containers retaining sealants reactive with atmospheric moisture in predetermined apportioned quantities.

~69033 SUMM~RY OF THE INVENTION
This invention presents to the art, novel packaging means particularly adaptable for packaging sealants reactive with atmospheric moisture. The novel packaging means presented by way of the present inven-tion is relatively simple, uncomplicated and inexpensive to manufacture. At the same time, the novel packaging means provides effective protection for sealants reac-tive with atmospheric moisture which are hermetically sealed inside the bag of the packaging means in one or more individual containers retaining predetermined appor-tioned quantities of sealant designed to minimize waste of unused sealant. Additionally, the novel packaging means of this invention including the hermetically sealed contents can be recycled and/or disposed of easily and with minimal effect or impact on the environment.
According to a broad aspect of ~he present invention there is provided a packaging means for sealants or adhesives reactive with atmospheric moistureO The packaging means comprises a bag of metal foil hermeti-cally sealed on all sealable edge portions by weld seams of plastomeric or polymeric adhesive materials coated on at least the internal edge surfaces of ths foil to be sealed. The metal foil bag is sealable -by folding over an opened edge several times. A plurality of sealed containers are hermetically sealed in the bag and retain a sealant or adhesive reactive with atmospheric moisture in a predetermined apportioned quantity. The containers are sealed by seals that can prevent at least any sub-stantial amount of atmospheric moisture from contacting sealant in the sealed containers and where at least one of the seals is a frangible seal. A dessicant material ~9~33 - is hermetically sealed in the bag with the containers.
DESCRIPTION OF THE DRAWINGS
Figure 1 shows a side view of packaging means o~ this invention showing a hermetically sealed metal foil bag and individual sealant container(s~ and dessicant material hermetically sealed inside the bag.
Figure 2 shows a cross-sectional view o~ the packaging means of Figure 1 along line II-II.
Figure 3 shows a tubular container retaining sealant reactlve with atmospheric moisture when packaged in hermetically sealed metal foil bag of Figures 1 and 2n - 3a ~.~6~33 ~ESCRIPTION OF 'l'III~ Pl~ RR~D E;'M130DIMk'N'I' -Essentially, the novel packaging rneans of this invelltioll includes a bag having two sides of thin metal foil having edges hermetically sealed by an adhesive layer of plastomeric or polymeric material. Particularly preferred adhesive, plastomeric or polymeric layer materials are heat activatable adhesive materials which can provide relatively wide weld seams of fused heat activated adhesive material hermetically sealing edges of the metal foil bag. The sides of the bag may be formed of one or two sheets of metal foil. If the bag is formed of two separate sheets of metal foil, an adhesive plastomeric or polymeric layer can be coated on one or both of the inner surfaces of each metal foil sheet material facir.g each other. Also, the adhesive plastomeric or polymeric layer can be coated over the entire inner surface of one or both of the sheets. Alternatively, only the edge portions of one or both of the inner surfaces to be sealed may carry the layer of adhesive plastomeric or polymeric material. The preferred bags of this invention are those formed by folding a sheet of metal foil and hermetically sealing the remaining three sides with a layer of adhesive plastomeric or polymçric material in tlle manners described above.
As mentioned, the novel packaging means of this invention is designed to package, store and deliver one or more individual containers retaining predetermined apportioned quanti.ties of sealants reactive with atmospheric moisture. In accordance "
2S with this invention, these individual containers are sealed but, ;
`
6~ 3 expensive, special;zed or absolute hermetic seals are not required because the container (s) is hermetically scclled insi(3e thc met11 foil bag. .9lso hermetically sealed inside the metal foil bag with the individual container (s) is a dessicant material. This dessicant material is designed to absorb any moisture which may contact sealant in the individual sealed containers during their packaging and storing in the metal foil bag or during removal of some or all of the individual container (s) from the metal foil bag.
For example, if all of the individual containers are not removed from the metal foil bag at the time the bag is opened, sealant in remaining container (s) can be protected against atmospheric moisture by simply folding over the opened edge of the metal foil bag a number of times. The dessicant material will therefore protect sealant in the individual container (s) during opening of the bag and removal of some of the container (s) . Also, the r dessicant material will protect sealant in a container (s) remaining in the bag from any atmospheric moisture later entering the bag through the folded opening of the metal foil bag.
The invention and the advantages obtained by practicing it will be better appreclated by the following detailed description taken in connection with ~igures 1, 2 and 3. Eiigures 1 and 2 show a bag 1 consisting of aluminum foil coated with an adhesive plastomeric or polymeric layer on both surfaces of the foil.
The bag is formed from one sheet which is folded together or creased on side 2. The remaining edges of bag I are hermetically sealed by weld seams 3, ~ and 5 formed in the adhesive plastomeric .
r~
or polymeric material layer on the inner surfaces of the aluminum foil. S~ince the plastomeric or polymeric material layer coated aluminum foil cannot be penetrated by atmospheric mo;sture and since weld seams 3, 4 and 5 hermetically seal the edges of bag 1, the contents of the bag are completely protected from 5 atmospheric moisture.
As shown in Figures 1 and 2, one or more individual container (s) 6 retaining sealant reactive with atmospheric moisture are hermetically sealed inside bag 1. Also hermetically sealed inside bag 1 is a dessicant retained in a container 7 fabricated 10 of a pourous material such as paper. The dessicant in container 7 absorbs moisture during the packaging operation and during the removal of containers 6 from bag 1. Also, the dessicant in container 7 will absorb any moisture which may enter an opened bag 1 through a folded opening of rnetal foil bag 1 thereby 15 protecting sealant in any container (s) 6 left in the opened bag 1.
Figure 3 shows a container 6 which retains sealant reactive with atmospheric moisture. As shown, container 6 is tubular shaped and may be fabricated of thin, plastomeric or polymeric 20 preferably semi-rigid sheet material or of thin walled plastomeric or polymeric tubing or of thin metal foil. One end of tubular container 6 is sealed by a weld seam 9 curving in an arc passing between longitudinal wall sections of container 6. Curved wèld seam 9 is preferred because corners which can provide 25 undesirable air-pockets in filling tubular container 6 with sealant ' .
~16~33 can be eliminated. The other end o~ tubular container 6 is sealed preferably by constricting end portior~ 8 SUCll FlS by pressing, twisting, folding or tying end portion 8. As already mentioned, sealed ends 8 and 9 of tubular container 6 need not provide absolute hermetic seals but the seals should be at least effective 5 to prevent any substantial amount of atmospheric moisture from contacting sealant in container 6. Also, one of the seals - preferably seal 8 - should provide a frangible seal, easily opened, broken or ruptured such as by untying, untwisting or unfolding or by the application of moderate compressive pressure so that the sealant can be easily discharged from container 6 for application to a surface or surfaces to be sealed.
From the foregoing description, the invention defined in the appended claims presents to the art novel packaging means which is relahvely simple, convenient and inexpensive but 15 can effectively protect sealants reactive with atmospheric moisture.
The novel sealing means of this invention are particularly applicable to the problems of those who require relatively small quantities of sealant but at the same time require minimal waste of unused sealant. Moreover, the materials used in the fabrication and 20 manufacture of the novel sealing means of this invention can be recycled in some cases or in any event, disposed of with minimum inconvenience to or effect on the environment.
