No tear pharmaceutical pouch
View Patent ↗A multi-layered pouch capable of holding pharmaceutical related items. The pouch includes first and second sides engaged along a plurality of extending and interconnected edges thereof and in order to define a hermetically sealed interior for holding the items. Each of the sides exhibits a multi-layered construction including an outer high density polymer film, coated with a clay material, a lower density polymer film secured to an exposed side of the high density polymer film, a metal foil layer secured to an exposed inner facing side of the lower density film, and a sealant resin layer secured to an exposed facing side of the foil layer. In use, the pouch exhibits tear resistant properties and such as which prevents a child from biting into and opening the pouch.
1. A multi-layered pouch for pharmaceutical use, comprising:
first and second sides engaged along a plurality of extending edges thereof to define a hermetically sealed interior, each of said sides further comprising:
an outermost oriented, high density polyethylene polymer film coated with a clay material;
a lower density polymer film secured to an inwardly facing side of said high density polymer film;
a metal foil layer secured to an exposed inwardly facing side of said lower density film; and
a sealant resin layer secured to an exposed inwardly facing side of said foil layer;
said pouch exhibiting tear resistant properties.
2. The pharmaceutical pouch as described in claim 1 , said clay coated high density polyethylene polymer film further comprising a gauge thickness established in a range of 200 to 300.
3. The pharmaceutical pouch as described in claim 1 , said lower density polymer film further comprising a low density polyethylene laminating resin.
4. The pharmaceutical pouch as described in claim 1 , said lower density polymer film further comprising a polyethylene/acid copolymer extrusion laminating resin.
5. The pharmaceutical pouch as described in claim 1 , said foil layer further comprising a 35 gauge aluminum foil.
6. The pharmaceutical pouch as described in claim 1 , said sealant resin further comprising a polyethylene/acid copolymer resin.
7. The pharmaceutical pouch as described in claim 1 , said sealant resin further comprising an lonomer extrusion resin.
8. The pharmaceutical pouch as described in claim 1 , said first and second sides each exhibiting a substantially rectangular shape having first, second, third and fourth sides.
9. The pharmaceutical pouch as described in claim 8 , further comprising heat scaling a bottom edge and first and second side extending edges of said sealing pouch.
10. The pharmaceutical pouch as described in claim 9 , further comprising an open top edge of said pouch being sealed following filling with the pharmaceutical related items.
11. A multi-layered pouch capable of holding at least one item, comprising:
first and second sheets of material engaged along a plurality of extending edges thereof to define a hermetically sealed interior for holding the items, each of said sheets further comprising:
a first oriented, high density polyethylene polymer film coated with a clay material;
a second polymer film secured to a facing side of said first polymer film;
a foil secured to an exposed facing side of said second film; and
a sealant secured to an exposed facing side of said foil;
said pouch exhibiting tear resistant properties.
12. The pouch as described in claim 11 , said second polymer film further comprising at least one of a polyethylene laminating resin and a polyethylene/acid copolymer extrusion laminating resin.
13. The pouch as described in claim 12 , said second polymer film exhibiting a density lower than said first polymer film.
14. The pouch as described in claim 11 , said foil further comprising an aluminum foil.
15. The pouch as described in claim 11 , said sealant further comprising at least one of a polyethylene/acid copolymer sealant resin and an Ionomer extrusion sealant resin.
16. A multi-layered pouch for pharmaceutical use, comprising:
first and second sides, each exhibiting a rectangular shape having first, second, third and fourth sides and which are heat sealingly engaged along extending and interconnected edges thereof to define a hennetically sealed interior, each of said sides further comprising:
a first outer oriented, high density polyethylene film exhibiting a first density and which is coated with a clay material;
a second polymer film including at least one of a polyethylene laminating resin and a polyethylene/acid copolymer extrusion laminating resin, said second film being secured to an inner facing side of said high density polymer film and exhibiting a second density less than that of said first polymer film;
an aluminum foil layer secured to an exposed inner facing side of said second polymer film; and
a sealant resin layer secured to an exposed inner facing side of said foil layer;
said pouch exhibiting tear resistant properties.
