Bleach Bottle Opener UK

Bleach Bottle Cap Opener

This works with some UK 750ml bleach bottles.

Here in the UK, Bleach bottles have a childproof cap that has to be firmly squeezed whilst turning it.

The issue is that it can be hard to squeeze to cap firmly enough whilst unscrewing it, particularly for the elderly or those with arthritis etc.

I designed this thing to make it easier to press-in the sides of the cap and simultaneously unscrew it.

So far, I have only tried it with products that have the following cap specification:

A 34mm diameter dome-shaped top part of the cap and below it a wider 43mm diameter section with two slots either side to allow the cap to be squeezed open.

(see photo).

The opener is designed to fit over the dome top section and fit into the two slots.

This locates the opener in the best position for squeezing the correct part of the lower section and helps to lock it in place while turning it open.

I have tried it with the following two products:

ASDA Thick Bleach (750ml)

Easy Seriously Thick bleach (750ml).

At the time of writing (March 2022) It looks like it may work with these similar looking products as they appear to use the same design:

Parazone Bleach

Morrisons Thick bleach?

Wilko Bleach

Aldi Power force bleach

LIDL W5 bleach

Waitrose Essential bleach

It probably won't work with those products below as they appear to have a different design cap:

Domestos bleach.

Tesco bleach

I have made a few prototypes using PLA with between 10 and 20% infill and 0.28 to 0.2mm resolution and both seem to work ok.

It doesn't need any printing supports.
