can a plastic container of this shape be manufactured?

[funtech]

Hi, I'm not well versed in blow molding. I need to make a container in the shape of the following pictures.

Essentially, it's just a regular bottle, but with two openings (protrusions) on the side, for connecting to tubes.

Can it even be manufactured? How can the protrusions on the side be manufactured? I talked to a maker of conventional bottles and they said they "don't have the machines to make the protrusions on the side."

thanks

Does it have to be blow moulding?
Could you create two halves and bond together?

Kinda what I was thinking, Cor. Thermoform two halves out of sheet material, connected. Fold over to make the shape, then heat stake it, glue, or ultrasonic weld.

But then, those darn nipples....

Actually, that's kind of how blow molding works.
The machine produces, by extrusion, sheet in the form of a tube called a parison, which may or may not be round. Then the mold closes over the tube, pinching and sealing the end and the periphery, and compressed gas injected through the center of the extrusion nozzle inflates the product. The mold opens after the product has cooled a bit, and it's sent on to have the ends and flash trimmed off.

A friend of mine from tech school days owns and runs an injection molding shop that does dozens of parts just like this for the medical industry, only not in olefins. They are typically molded in 2 or more parts, and electronically welded together. He has had no quality issues.

Have you considered glass?

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
