Dust free absorbent packaging materials
View Patent ↗A liquid-absorbing, impact-absorbing packaging container for protecting packaged items such as bottled liquids, while providing absorbency in the event of a liquid spill. The container material is created from a mixture of an inorganic liquid-absorbing agent such as vermiculite, and a cellulosic material such as paper pulp, which mixture is then formed into a container material, for packaging an article such as a glass bottle. The containers and container materials of this invention are substantially free of dust and/or loose particles.
1. A liquid-absorbing, and impact-absorbing packaging container consisting of a mixture of an inorganic liquid-absorbing agent selected from the group consisting of vermiculite, SiO 2 , amorphous alumina silicate gel, dehydrated aluminum-silicate, and combinations thereof; and a cellulosic material selected from the group consisting of cellulosic paper, cellulosic particles, cellulosic flour, cellulosic pulp, and combinations thereof; said container being substantially free of dust or loose particles.
2. The container of claim 1 wherein the liquid-absorbing agent is present in the mixture in an amount of from about 10% by wt. to about 50% by wt. of the mixture.
3. The container of claim 1 wherein the liquid-absorbing agent comprises vermiculite.
4. The container of claim 1 wherein the liquid-absorbing agent is present in the form of particles.
5. The container of claim 1 which has been formed by molding the mixture into a container.
6. A liquid-absorbing and impact-absorbing packaging container material consisting of a mixture of an inorganic liquid-absorbing agent selected from the group consisting of vermiculite, SiO 2 , amorphous alumina silicate gel, dehydrated aluminum-silicate, and combinations thereof; and a cellulosic material selected from the group consisting of cellulosic paper, cellulosic particles, cellulosic flour, cellulosic pulp, and combinations thereof; said material being substantially free of dust or loose particles and which is in the form of a rollable sheet.
7. The container material of claim 6 which is in the form of a rollable sheet having an array of concavities.
8. A container comprising a rollable sheet the container material of claim 6 .
9. A packaging article comprising the container of claim 1 .
10. The container material of claim 6 wherein the rollable sheet comprises a pattern of impact-absorbing ridges.
11. A packaging article comprising the container material of claim 10 .
12. A product which comprises a liquid-absorbing, and impact-absorbing packaging container consisting of a mixture of an inorganic liquid-absorbing agent selected from the group consisting of vermiculite, SiO 2 , amorphous alumina silicate gel, dehydrated aluminum-silicate, and combinations thereof; and a cellulosic material selected from the group consisting of cellulosic paper, cellulosic particles, cellulosic flour, cellulosic pulp, and combinations thereof; and a liquid containing, breakable bottle supported in the container.
