A teether is provided for infant use. The teether comprises an exterior portion and a mouthpiece wherein the mouthpiece includes a substantially U-shaped biting section comprising first and second arms extending from a central portion. At least part of said central portion is resiliently collapsible upon application of pressure thereto during use of the teether by an infant.
1. A teether or soother for infant use comprising:
a rigid support ring,
a rigid exterior portion, an outermost diameter of the rigid support ring being substantially equal to an outermost diameter of the rigid exterior portion, and the rigid support ring being configured to reside between the infant's face and the rigid exterior portion during use by the infant, and
a flexible mouthpiece comprising a membrane of nonporous material extending towards the rigid exterior portion and having an outermost perimeter,
wherein the flexible mouthpiece is secured in place by the rigid support ring and the rigid exterior portion by mechanically trapping and enclosing a profile of the outermost perimeter of the mouthpiece in a juncture between the rigid support ring and the rigid exterior portion at an outermost periphery of an annular region of the rigid exterior portion, and wherein the profile of the outermost perimeter is mechanically trapped by the juncture in at least two directions, the directions comprising a radial direction and an axial direction, as a result of a cross section of the outermost perimeter being in contact with surfaces of the juncture on at least four sides.
2. The teether or soother of claim 1 wherein the entire outermost perimeter of the mouthpiece is mechanically trapped and enclosed within the juncture.
3. The teether or soother of claim 1 wherein the profile of the mouthpiece mechanically trapped is substantially square in cross-section.
4. The teether or soother of claim 1 wherein the mouthpiece comprises a central section including a mouthpiece cavity.
5. The teether or soother of claim 1 wherein the mouthpiece comprises a central section including a nipple.
6. The teether or soother of claim 1 wherein the rigid support ring and rigid exterior portion are permanently joined together.
7. The teether or soother of claim 1 wherein a central portion of the mouthpiece is U-shaped.
8. The teether or soother of claim 1 wherein the flexible mouthpiece is secured in place by the rigid support ring and the rigid exterior portion without pins.
9. The teether or soother of claim 1 wherein a surface of the rigid support ring is profiled away from the infant's face towards the outermost periphery of the rigid exterior portion.
10. A teether or soother for infant use comprising:
a flexible mouthpiece comprising a membrane of nonporous material and having an outermost perimeter,
a rigid support ring, and
a rigid exterior portion, an outermost diameter of the rigid support ring being substantially equal to an outermost diameter of the rigid exterior portion, and the rigid support ring being configured to reside between the infant's face and the rigid exterior portion during use by the infant,
wherein the flexible mouthpiece is secured in place by the rigid support ring and the rigid exterior portion by mechanically trapping and enclosing a profile of the outermost perimeter of the mouthpiece in a juncture between the rigid support ring and the rigid exterior portion at an outermost periphery of an annular region of the rigid exterior portion in at least two directions, the directions comprising a radial direction and an axial direction relative to a central axis of the rigid support ring, as a result of a cross section of the outermost perimeter being in contact with surfaces of the juncture on at least four sides.
11. The teether or soother of claim 10 wherein a cavity is formed between the rigid support ring and the rigid exterior portion, and a portion of the mouthpiece is mechanically trapped within the cavity.
12. The teether or soother of claim 11 wherein the portion of the mouthpiece mechanically trapped is substantially square in cross-section.
13. The teether or soother of claim 10 wherein the mouthpiece comprises a central section including a mouthpiece cavity.
14. A teether or soother for infant use comprising:
a flexible mouthpiece,
a rigid support ring and
a rigid exterior portion, an outermost diameter of the rigid support ring is substantially equal to an outermost diameter of the rigid exterior portion, and the rigid support ring being configured to reside between the infant's face and the rigid exterior portion during use by the infant,
the flexible mouthpiece comprising a membrane of nonporous material extending towards the rigid support ring and the rigid exterior portion,
wherein a profile of an outermost perimeter of the membrane is mechanically trapped and enclosed in a juncture between the rigid support ring and the rigid exterior portion at an outermost periphery of an annular region of the rigid exterior portion and the outer perimeter is mechanically trapped by the juncture in at least two directions, the directions comprising a radial direction and an axial direction, as a result of a cross section of the outermost perimeter being in contact with surfaces of the juncture on at least four sides.
15. The teether or soother of claim 14 wherein a cavity is formed between the rigid support ring and the rigid exterior portion, and a portion of the mouthpiece is mechanically trapped within the cavity.
16. The teether or soother of claim 15 wherein the portion of the mouthpiece mechanically trapped is substantially square in cross-section.
17. The teether or soother of claim 15 wherein the mouthpiece extends from the cavity via a narrow channel.
18. The teether or soother of claim 14 wherein the mouthpiece comprises a central section including a mouthpiece cavity.
19. The teether or soother of claim 14 wherein the mouthpiece comprises a central section including a hollow nipple.
20. The teether or soother of claim 14 wherein a portion of the flexible mouthpiece is resiliently collapsible.
