ideas for bag closure

Postby davemal » Sun 04 Feb, 2018 4:14 pm

Hi,

Although not strictly bushwalking related, I thought that I would try my luck asking for some thoughts from the good MYOG people

I am making a bag to store some cricket/tennis balls for my son and am stuck at designing a closure. Think of a bike pannier - I have a old panniers that i am thinking of modifying...asymetrical shape with a straight rigid inside edge and then bag in a semi-circular shape. Ideally I would like it to open up fully naturally and close fully.

A throat and drawstring would have dangly bits when open and get in the way. Would like to avoid
A zip - the shape makes it difficult & may require dangly bits
Roll or fold top is essentially a throat and same issue.
Magnets - no doubt would close when you least want it. Tricky design
velcro - similar to zips & magnets but added irritation from the hooks.

Out of these I think a drawstring or zip are the leading options.

Any other suggestions ? Anything obvious that I may be missing ?

Any thoughts appreciated as this has been doing my head in !

cheers

I would sew a flap to the back that then folds over and attaches to the bag with either magnets or Velcro.
Velcro would probably be easier.

Thanks Chris,

Amazing what triggers an idea. I originally discounted a cover because of the dangly bits. But while I was struggling to sleep last night I was able to come to the solution following Chris' suggestion.

Twin parallel zips around the lip. The zip slider tabs joined by some cord so that they work together. The cover piece will then fall into the rear of the bag and you wont even know that its there.

Thanks for listening to my mind ticking !

If you made it one zip in a U shape - like some backpacks, then the two pulls can be brought together thus fully closing the opening... any cord could be tucked inside the bag just before full closure. And if needed a lock can be made through the two pulls to stop openings -accidental or otherwise.
