TEETHER

Abstract

A teether is disclosed that is capable of retaining and presenting solid, cold, and/or damp food to a teething child. The teether has a top piece and a bottom piece. An opening in the top piece has a plurality of lobes and a like number of retaining teeth. The retaining teeth are configured to capture properly sized food, so that a teething child is able to gum or gnaw on the food, but not remove the food from the teether. If the child places too much force on the food, the food falls through the opening into a vessel, where is remains until removed by an adult.

[0023] Looking at FIG. 4, the present invention 1 has a top piece 2 and a bottom piece 3.

[0024] FIGS. 1-2 show the top piece 2 in detail. FIG. 1 is a top view of the top piece 2. FIG. 2 is a side view of the top piece 2. The top piece 2 has an outer top surface 8, an annular flange 7, and an outer cylindrical surface 9, 71. The cylindrical surface 9, 71 is bisected by the annular flange 7, creating an upper cylindrical surface 9, and a lower cylindrical surface 71. The upper cylindrical surface 9 is orthogonal to the outer top surface 8 and the flange 7; the lower cylindrical surface 71 is orthogonal to the flange 7.

[0025] The top piece 2 has a height 21, a first diameter 22, and a second diameter 23. The first diameter 22 is the diameter 22 of the outer cylindrical surface 9, 71. The upper cylindrical surface 9 terminates at the top outer surface 8. The lower cylindrical surface 71 terminates in an opened rim 26. The upper cylindrical surface 9 and the lower cylindrical surface 71 both abut the flange 7. The opened rim 26 of the top piece 2 mates with the bottom piece 3. The second diameter 23 is the outer perimeter 72 of the flange 7. The flange 7 has a top surface 7 and a bottom surface 27.

[0026] The top piece 2 has an opening 4 in its top surface 8, through which a piece of solid, cold, and/or damp food 333 can be presented to a teething child [See FIG. 6]. The opening 4 resembles a plus sign 4. The opening 4 is defined by a continuous edge 6 in the top surface 8. The opening 4 has plurality of lobes 5. The plurality of lobes 5 are connected with a like number of rounded teeth 61. In the exemplary embodiment, as shown in FIGS. 1 and 2, the opening 4 has four lobes 5. The four lobes 5 are connected by four rounded teeth 61. Each lobe 5 is defined by three edge segments 65, 67, 66 connected by two fillet segments 69, 68. The four rounded teeth 61 connecting the four lobes 5 serve the function of retention teeth 61 for pieces of food 333 inserted into the opening 4. The retention teeth 61 hold and retain hard, cold, and/or damp food 333, so that a child may gnaw on the food 333 to relieve the discomfort of teething.

[0027] FIG. 3 shows the bottom piece 3. The bottom piece 3 has a vessel 34, a stem 11, 12, and a base 19. In this embodiment, the stem 11, 12 is constructed from orthogonally joined planar members 11, 12. The base 19 has defined feet 39. An optional opening 32 can be placed in the stem 11, 12 or foot 19, to attach a tether 400 to the teether 1. The bottom piece 3 has an opening 40 to the inside of the vessel 34. The bottom piece 3 has a diameter 24 defining the size of the opening 40. The vessel 34 has an exterior surface 34. The bottom piece 3 has a retention rim 13, which mates with a retention lip molded to the inner cylindrical surface of the top piece 2.

[0028] FIGS. 4 and 5 show the present invention 1, a teether, with the top piece 3 and bottom piece 4 in place. FIG. 4 is a perspective view; FIG. 5 is a side vertical cut-away. The top piece 2 has an outer top surface 7, a flange 7, and a side surface 9. There is an opening 4 is the outer top surface 8. The opening 4 has four lobes 5 and four retention teeth 61. The retention teeth 61 are fabricated from a stiff but flexible material.

[0029] The lower piece 3 has a vessel 34, a stem 31, and a base 33. In this embodiment, the stem 31 is cylindrical as is the outer diameter of the base 33. An opening 32 in the stem 31 allows for the attachment of a retaining tether 400. The interior 35 of the vessel 34 of the bottom piece 3 is designed to receive pieces of food 333, if pushed through the retention teeth 61 in the opening 4 of the top piece 2. The opening 40 in the bottom piece 3 allows for the food to fall through the retention teeth 61 where it is retained in the interior 35 of the vessel 34 of the bottom piece 3.

[0030] As shown in FIG. 5, the stem 31 is solid 37. The vessel 34 has a thickness 36. The flange 7 has a thickness 52. The lower surface 71 has a thickness 51. The base 33 has a thickness 188 and a bottom surface 39. The inner surface of the top piece 2 has a lip 50 that captures the retention rim 13 of the lower piece 3. The opening 32 in the stem 33 is a cylinder 38 with an interior cylindrical surface 38. A tether 400 can pass through the stem and secure the teether 1. The outer top surface 8 of the top piece 2 has an inner top surface 88, which is oriented towards the interior 35 of the vessel 34 when the two pieces 2, 3 are mated

[0031] FIG. 6 shows the present invention 1, a teether 1, retaining a piece of solid, cold, and/or damp food 333. To insert food 333, the food 333 is pressed into the retention teeth 61 from the top. Alternately, food 333 can be inserted into the retention teeth 61 from the bottom. The top piece 2 is separated from the bottom piece 3. A piece of food 333 is firmly inserted into the teeth 61 in the opening 4, from the inner-top-surface side 88 of the outer top surface 8. When the food is firmly retained by the teeth 61, the top piece 2 is mated with the bottom piece 3, by aligning the outer diameter of the opening 24 of the bottom piece 3 with the first diameter 22 of the top piece 2. The top piece 2 and bottom piece 3 are then pressed together until the lip 50 in the top piece engages and captures the retention rim 13 of the bottom piece 3. The food 333 is retained by the retention teeth 61 in the opening 4 in the top piece 2.

[0032] When a child teeths on the food 333, the food 333 will remain in place. If the child presses the food 333 with too much force, the food 333 will land in the interior 35 of the vessel 34. In this way, the teether 1 can be used to present appropriate food 333 to a teething child, while eliminating the hazard of choking. Food 333 cannot be pulled out through the retaining teeth 61 by a teething child under normal conditions. Said another way, the retention force exerted by the retention teeth 61 on the food 333 makes it so that the food 333 can be driven into the interior 35 of the vessel 34 of the bottom piece 3 but cannot be extracted outward, away from the vessel 34. If a child should drive the food 333 into the interior 35 of the vessel 34, the food 333 will remain in the interior 35 of the vessel 34 until removed by an adult. The teether 1 also prevents the child from abandoning half-teethed food stuff all around a house.

[0033] The teether is ideally fabricated as two mating pieces from a rigid, inert structural plastic such as PP, virgin HDPE, and PET. Some materials, like ABS, should be avoided because the material is not approved for food containers by the FDA, as it contains hazardous substances in its raw form. Some materials, like PC, are approved for use with food, but many parents are leery of Bisphenol-A which can leach out of PC. Therefore, one skilled in the art may wish avoid PC, although PC has the material properties with which to form the present invention 1. PLA should also be avoided, because its biodegradable nature makes it unsafe for a teether for young children. PLA will leach its constituent parts when repeatedly exposed to saliva. The material for the teether 1 should not leach due to saliva.

[0034] Portions of the present invention can be textured or use a rubberized surface. The stem 11, 12, 31 can be textured or it can use a rubberized material to improve the grip. The teeth 61 of the top piece 2 can be fabricated from stiff structural plastics or from stiff thermoplastic elastomers.

For example, two functions/acts shown or described in succession may in fact be executed substantially concurrently or the functions/acts may sometimes be executed in the reverse order, depending upon the functionality/acts involved. While certain embodiments have been described, other embodiments may exist. Further, the disclosed methods' functions/acts may be modified in any manner, including by reordering functions/acts and/or inserting or deleting functions/acts, without departing from the spirit of the claimed subject matter.
