That's a really smart and practical question! A waste bin with a smaller opening is a great idea to help discourage litter and overflow, especially in common areas or if you have kids. The smaller opening encourages people to actually place trash inside rather than tossing it, which often leads to misses and messes around the bin.
The good news is, many standard kitchen or office trash cans are designed with this in mind—they have an opening just large enough for common waste but not so big that it invites careless throwing. When shopping, look for bins described as "step-on" or "pedal" models with a flip lid. The lid usually has a defined opening. Also, consider "rectangular" or "slender" designs over wide, round ones.
Now, about fitting large bags: this is the trickier part. A small opening doesn't necessarily mean a small bin *body*. You can absolutely find bins with a narrower top and a wider base or body. Here’s what to do:
1. Check the Capacity: Focus on the bin's volume (e.g., 30 liters, 50 liters). A tall, 50-liter bin can use a large bag but might have a top opening of only 12 inches across.
2. Look for "Wide-Body" Designs: Some bins are specifically shaped like a "D" or have a flared design to maximize bag capacity underneath a controlled opening.
3. Measure Your Bags: Know the dimensions of your large bags. Then, check the product specifications for the bin's internal body width/depth, not just the top opening.
A great solution is a touch-free sensor bin with a small, automated sliding lid. It opens only when needed, perfectly controlling litter and odor, and most can handle standard large kitchen bags inside. It might be the perfect blend of function you're looking for!
