United States Patent Oh 3,085,681 Patented Apr. 16, 1963 ice 3,085,681 COMPOUNDYNG ANl) PACKAGING UNIT Henry L. Fazzan', New York, N.Y. (KS3- 30 16th Ave., Flushing 55, N.Y.) Filed July 16, 1959, Ser. N 827,483 6 Claims. (Cl. 20G- 47) This invention relates to a unit for so packaging the several ingredients or components of an ultimate cornand contemplated by this invention.
By packaging the several ingredients produce the desired ultimate compound.
With the above and other objects in View, as will be apparent the invention consists in the construction, compound or mixture;
FIG. 5 is an elevation of another type of packaging or compounding unit made in accordance with this invention;
FIG. 6 is a like elevation of still another embodiment of a packaging and compounding unit following the teachings hereof;
FIG. 8 is an edge elevation of part of the tear tab to illustrate a modification thereof to facilitate the engagement thereof.
as an example, it being understood that the packaging and compounding of other resins and/or materials may be carried out in the subject unit without change or variation save perhaps in size and capacity.
To carry out this invention several envelopes or conthe outer envelope or container for blending or mixing Though several materials,
transparent, clear, strong, thin and is incompatible to the ingredients to be compounded within the unit.
Since one is provided for each ingredient to be compounded or mlXed with the contents of the outer envelope 10 the number of such ingredients determined by its specic function and capacity. As, in the quantity of epoxy resin exceeds the quantity of the hardener or activator required,
cylinder or envelope yl0.
By reversing the position of the envelope 10 i.e., bringing its open end uppermost, it may receive and hold a measured quantity of epoxy resin. After the overall or outer envelope 10 is partially lled with epoxy resin through its remaining open end that end is heat sealed or cemented, as at 16, thereby confining the epoxy resin and the subsidiary envelope 11 in the outer or overall envelope 10. It is advisable to only partially fill the outer envelope 10 to thereby allow ample space for the blending and mixing of the contents of envelope 10 with the contents of subsidiary envelope `11 when released into the outer or overall envelope 10 by manipulation of the unit.
In order to open the inner or subsidiary envelope 11 to allow its contents to escape into the overall or outer envelope 10 a tear tab `17 is heat sealed or cemented to and along the outer surface of one side of said envelope. This tear tab is a relatively long, narrow strip or tape of polyethylene having one end portion 17 resting flush against and sealed throughout its length to the material of the envelope 11. The opposite end portion 17, which is unattached to the envelope 11, is then bent over the remainder of the tear tab 17 to project beyond the inner end of the subsidiary envelope 1l. Any pull on the end portion 17" of the tear tab 17 will cause that portion 17 of such tab sealed or cemented to the envelope 11 to tear the latter and allow its contents to escape into the envelope 10. To insure the successful operation of the tear tab 17 without breaking, it is made of polyethylene somewhat thicker than the polyethylene of which the envelopes 10 and 11 are fabricated.
Of course any required number of subsidiary envelopes 11 may be enclosed in and secured to the outer envelope 10, in which event each may be provided with its individual tear tab 17. on the outer or overall envelope not illustrated for it would be identical with the tear tab 17 shown on the inner or secondary envelope construction and operation. Indeed, as the outer envelope 10 of the unit usually is fully accessible, a tear tab is not necessary since it may be easily cut or otherwise opened when it is desired to release the compound blended or mixed therein. However when the subject compounding unit is enclosed or covered as in the impregnating kit disclosed in copending application Serial No. 810,468. filed May l, 1959, a tear tab 17 on the outer envelope 10 would be advantageous if not essential.
In FIGS. 5 and 6 the outer or end portion 17" of the tear tab 17 is free and may be grasped and manipulated through the wall of the outer envelope 10. The end portion 17" of the tear tab 17 shown in FIG. 5 may be plain; or its extremity 17a may be folded back for a short distance to rest hush against the body of end portion `17" Where it can be heat sealed or cemented to create a double thickness at the terminal of said free end portion all as shown in FIG. 8. This would facilitate grasping the tear tab 17 as above described.
In FIG. 6 the free extremity of end portion 17" is looped through a ring 18 of any suitable material, preferably synthetic resin or like material. Thereafter such extremity is heat sealed or cemented to the portion 17 above the ring 18 as at 19. nently secured to the free end portion tab 17 and provides means to facilitate the engagement of the end portion 17 through the wall of the outer or overall envelope `10.
In FIGS. 1 to 4 inc., the unit is so arranged that the tear tab 17 may be pulled to open the inner or subsidiary envelope 1t1 and release its contents without direct or indirect manual engagement of such tab. Taking advantage of the pliability and flexibility of the polyethylene of which the envelopes or containers are fabricated the outer or overall envelope or telescoped by forming a lap or fold 20 around the wall thereof medially of its ends. This lap or fold 20 is disposed inwardly of the envelope 10 to closely underlie the wall thereof as shown in FIGS. l and 4. At that point in the assembly of the unit one end of the outer envelope 10 is open while its opposite end contains the secondary or subsidiary envelope 11 which is hxedly held in place by the engagement of its anchoring tab 14 in the seal 15 that closes that end of envelope 10. The end portion 17" of the tear tab 17 is only long enough to just reach the open end of the Outer envelope 10 after the fold 20 is made and located. Thus, after the outer envelope 10 has received its quota of epoxy resin, the extremity of this relatively short tear tab end portion 17" is engaged by and in the seal 16 which closes that end of the outer envelope 10.
It is apparent from the foregoing that the shortened or telescoped outer envelope 10 is so arranged that the length of the end portion 17'I of the tear tab 17 plus the length of the contained inner or secondary envelope 11 substantially equals the shortened or telescoped length of said outer envelope 1t) and is appreciably less than the normal or expanded length of said outer envelope 10. Hence by grasping the ends 15 and 16 of the shortened outer envelope 10 and exerting a longitudinal pull thereon the outer envelope 10 is restored to its normal length and the tear tab 17 is consequently drawn to tear open the inner envelope 11.
What is claimed is:
