Abstract
The present invention provides a packaged cementitious product including a bag formed of a polymeric material. The bag has first and second sealed ends. The first end has a first tab extending therefrom defining at least one aperture therethrough so that the first tab defines a first handle. The second end has a second tab extending therefrom defining at least one aperture therethrough so that the second tab defines a second handle. A cementitious product is sealed within the bag, and wherein the first and second handles facilitate the handling of the packaged cementitious product.
Claims17
A method for packaging cementitious material using an automated machine, the method comprising:
- providing a roll of tubular polymeric film material;
- dispensing the tubular polymeric film material using the automated machine;
- sealing the tubular polymeric film to form a first seal;
- cutting the tubular polymeric film material at a predetermined distance from the first seal to form a bag, the bag comprising first and second ends, the first end comprising the first seal and defining a first tab extending therefrom;
- sealing the distal edge of the first tab;
- forming at least one aperture through the first tab so that the first tab defines a first handle;
- filling the bag with a predetermined amount of cementitious material;
- cleaning the inside edges of the second end of the bag;
- sealing the second end of the bag so as to form a second tab extending therefrom;
- sealing the distal edge of the second tab;
- forming at least one aperture through the second tab so that the second tab defines a second handle;
- and
- wherein, the at least one aperture in the first tab and the at least one aperture in the second tab are at least partially sealed so that the first and second handles together are capable of supporting at least approximately twenty-nine (29) pounds of weight without any further reinforcement.
