bag scale
Bag holder indicates single/double bagging | |
In my local supermarket, groceries are almost always double bagged, even if it's probably not necessary. Also, the cashier will put less into the bags than they can really hold, just to be safe and avoid the risk of breaking a bag.
This is pretty wasteful.
Suppose the gadget which dispenses/holds
bags open while they are being filled had a scale underneath it, to keep track of how much weight is in the bag being filled.
This scale wouldn't indicate weight with a dial or digital display; it would indicate weight with a simple led light, indicating "single bag," "double bag," "triple bag," or "too much for any number of bags."
As the bagger fills up the bag on the scale, which light is activated would change, possibly accompanied by an audible bell, to notify him/her to either add another bag, or remove the last item and put the bag into the cart.
This idea could even be implemented mechanically, though I expect digital would be cheaper.

There are factors other than weight in the critical failure of shopping bags. To demonstrate this stack three bricks in the bottom of a bag. Most shopping bags will tear under this load. Now spread the bricks on the bottom of the bag. Generally the bag will survive. Distribution of load is as critical as total weight. A plastic bag cannot lift a single sharp knife, if the point is facing down. |

We already have bag scales here in Aus at most woolworths stores but we more commonly use greenbags over plastic bags these days so there's no plastic bag waste at all. |

Here in Canada, grocery chains are working diligently to deprecate plastic bags. Shoppers purchase very inexpensive ($0.25) reusabale cloth bags, which we bring back to the store the next time we shop. Many grocers have eradicated plastic altogether. |

Inventing a complex method for metering these bags is silly when the better solution is to stop using them entirely. So this one gets a fishbone from me -- |

I'm with you on that one gonzola. The cloth bags are the way to go. |
