Abstract

A gum exercise device, such as a pacifier which is formed at least in part of a hydrophilic plastic and which has a material receiving cavity therein so that medicaments, flavors or the like can be conveniently released from the device upon normal chewing action.

Claims

1. A pacifier comprising a disclike base member having an aperture therein, a hollow nipple member having a flange attached to the base member adjacent said aperture to secure the same in position and having a plurality of perforations therein, a filling of a hydrophilic plastic material within the nipple, a cavity within the filling communicating with the aperture in the base, and closure means within the aperture for closing said cavity, whereby a soluble material can be placed in said cavity and saliva will cause said material to diffuse through said body portion into the mouth upon chewing on said device.

2. A pacifier according to claim 1 wherein the hydrophilic plastic is an infrequently cross-linked hydrophilic acrylate or methacrylate.

3. A pacifier according to claim 2, wherein the acrylate or methacrylate is selected from the group consisting of hydroxyethyl acrylate, hydroxypropyl acrylate, hydroxyethyl methacrylate and hydroxypropyl methacrylate.

4. A pacifier comprising a body portion formed at least in part of a hydrophilic plastic, said hydrophilic plastic having as a characteristic the capability of transmitting liquids therethrough when wet and barring the transmission of solids therethrough when dry, a cavity defined within said hydrophilic plastic part of said body portion, said cavity being adapted for reception and retention of a material when said hydrophilic plastic is dry, said material passing from said cavity through said hydrophilic plastic to the surface thereof when said hydrophilic plastic is wet with saliva or the like.

5. A pacifier according to claim 4 including a base means, a hollow membrane carried by said base means and having apertures therethrough, said hollow membrane being at least partially filled by said hydrophilic plastic.

6. A pacifier according to claim 4 wherein the hydrophilic plastic is an infrequently cross-linked hydrophilic acrylate or methacrylate.

7. A pacifier according to claim 6, wherein the acrylate or methacrylate is selected from the group consisting of hydroxyethyl acrylate, hydroxypropyl acrylate, hydroxyethyl methacrylate and hydroxypropyl methacrylate.
