For most caps yes. But have you encountered poorly manufactured ones, that are essentially defective, require vices and power tools?
Not yet. Though my older spouse (who is still recovering from a broken dominant wrist) has run into the strength problem.
Apparently even the prez had troubles with those safety caps. Bob Woodward said Richard Nixon asked presidential aide Stephen Bull to open a pill bottle for him. Bull noticed the container had teeth marks where Nixon had apparently tried to chew his way into the container. Funny thing is Nixon signed the bill in 1970 that ordered the use of child-proof containers. IIRC, Nixon would have been around 60 at the time of the alleged incident as he was born in 1913.
It's a bit strange on the childproof caps. I would expect there to be some sort of general standard? I have some very "dangerous" items and the special caps could be defeated by an infant (poetic license). While some marginally somewhat minor danger compounds arrive in a package that requires massive brain and brawn. kris
Pharmacy switched to caps that can be flipped for non-child proof use. Thing is the anti-tamper mechanism means there is a lip on the cap that can be uncomfortable to grip when flipped. Your pharmacy might have straight, non-anti-tamper caps available if you ask.
My understanding is that they are required to provide a non-CRC (non child resistant container) when requested.
Channel locks alone won’t cut it; you need simultaneous compression between the underside of child-proof cap and top of bottle, to hopefully mesh the internal teeth, paramount to achieve counterclockwise rotation of the actual cap. Coupling channel-locks (or self-locking pliers to dismiss the need for three hands) with a vice or hydraulic press, success (aka bottle opening), may be achieved. Or the bottle walls may collapse, split open, and there you go, contents exposed and able to be pried out through the gaps. alternately: mount bottle upside down on lath style mechanism, bring cutter to bear to remove bottle bottom, pour contents into regular jar, spent jam or mustard jar for example, seems feasible. oh we’ll get there.
Or, just find out what the thread pitch is, and 3D-print a cap. Need to get the old bottle cap off, but it'll be the last time you need to go through that. Doesn't need to conform to whatever regs the original did, if it's just you in the house using it. Any children however... maybe do need that lathe to fab up a manual adult-proof-cap opener that adapts to a bunch of container designs
Having bought a set of tires last week, I now see a news feed overrun with tire ads. Holding out for the day there's enough AI in the ad placement algorithm to figure out somebody who just bought a set of tires maybe isn't the hottest prospect for a bunch more tire ads just now.
I got a wall-mount exhaust fan through a local automotive/hardware place a few months back, and my reddit feed regularly includes a post from the place, with a pic of the fan (or alternate sizes) with the admonishment "that project is not going to finish itself", and perhaps I should visit them for additional tools. Project's done btw.
