No odour for 2 weeks

we have had a poo in a poo bag in the dicky bag in the back of the car for 2 weeks. We keep forgetting about it because we don’t have any odour to remind us but find it when we are out and about; but not near a poo bin to empty it. The odour seal is definitely working as the air freshener disc is still in the wrapper in the bottom of the bag.

Thanks
