Abstract

A beverage container is provided with a hydrophobic vent consisting of a relatively thick and rigid disc-shaped piece of macroporous plastic having pore sizes averaging from 7-350 microns. The vent can be welded, molded or secured to the sidewall, bottom or cap of a plastic beverage container thus eliminating all moving parts. The macroporous plastic is resistant to oxidative abrasion, contamination and wetting and is strong enough to resist breakage. In one embodiment a baby bottle is provided which consists of a plastic bottle body, a nipple, and means for fastening the nipple to the bottle body. The bottle body is provided with a macroporous plastic vent which can be welded, molded or secured to the sidewall or bottom of the bottle body thus eliminating all moving parts. The bottle body can be washed repeatedly as a single unit with the vent intact.

Claims

1. A vented beverage container of the type having a drinking spout and a vent where said vent is made from a sintered macroporous substrate and said vent is permanently secured to the container so the container and vent form an integral one piece unit.

2. A vented beverage container according to claim 1 wherein the macroporous substrate has pore sizes ranging from 7 to 350 microns.

3. A vented beverage container according to claim 2 wherein said vent is disc or plug shaped.

4. A vented beverage container according to claim 3 wherein said disk-shaped vent is from 0.025″

to 0.25″

thick.

5. A vented baby bottle wherein said baby bottle is the type that utilizes a nipple and a vent and said vent is made from sintered macroporous plastic permanently secured to said bottle so said bottle and vent form an integral one piece unit.

6. A vented baby bottle according to claim 5 wherein the macroporous plastic has pore sizes ranging from 7 to 350 microns.

7. A vented baby bottle according to claim 6 wherein said vent is disc or plug shaped.

8. A vented baby bottle according to claim 7 wherein said vent is from 0.025″

to 0.25″

thick.

9. A vented baby bottle wherein said baby bottle comprises a plastic bottle body, a nipple, means for securing said nipple to said bottle body, a sintered macroporous plastic vent, and means for permanently securing said vent to said bottle body so said vent and bottle body form an integral one piece unit.

10. A vented baby bottle according to claim 9 wherein the macroporous plastic has pore sizes ranging from 7 to 350 microns.

11. A vented baby bottle according to claim 10 wherein said vent is flat and disc shaped.

12. A vented baby bottle according to claim 11 wherein said vent is from {fraction (1/16)}″

to ¼

″

thick.
