This invention relates to one or more classifications and sub-classifications for devices for administering food or medicine and baby comforters. Specifically, this invention is a baby teether capable of retaining and presenting hard foods to a child during teething.
According to the CDC, infants are defined as children under the age of one, and toddlers are defined as children between the ages of one and three. Teething is a process that all children experience, that straddles the infant and toddler stages of development. At about three months, babies start putting things in their mouths, resulting in the child drooling. This is usually the first sign that a child is teething. According to the American Academy of Pediatrics (“AAP”), most children get their first tooth around 6 months of age and have a complete set of 20 deciduous teeth by 30 months of age.
As the AAP states, the information most new parents receive about teething, and the symptoms surrounding it, are ill-defined and nonevidence-based. The symptoms most associated with teething are fussiness, drooling, changes in sleep and eating patterns, runny nose (aka rhinorrhea), rash, and diarrhea. The most accurate way to determine if a child is teething is to examine their gums. If the gums have isolated swelling, redness, or soreness, the child is teething.
The AAP suggests that a child experiencing teething pain be given solid, cold, and damp items to chew on. The AAP specifically rejects liquid- or gel-filled rings, numbing gels, homeopathics, and amber necklaces as treatments for teething pain.
As most parents know, there is no perfect solution to teething, because no item satisfies all three of the attributes given by the AAP. Gel-filled teething rings, which can be placed in the freezer, are not recommended because they are not solid. Solid teething rings are not generally effective, because they are not cold and damp. Many foods, such as hard apples, cucumbers, and similar fruits and vegetables meet the AAP's guidelines, but teething children often lack the dexterity to grasp the wet and slippery surfaces of such foods. What parents really need for their teething children is a product that securely captures cold, damp, solid food stuffs in a way that allow infants and toddlers to hold it and gum on it.
This summary is intended to disclose the present invention, a teether. Embodiments of the invention are presented to illustrate and inform one skilled in the art. The teether captures cold, damp, solid food, such as apples, cucumbers, pears, and carrots, and presents it to a teething child in a manner in which the child can grasp and manipulate.
The present invention, a teether, is comprised of two pieces: a top piece and a bottom piece, that mate when used. The top piece has an outer top surface, an outer cylindrical surface, and a flange. The flange bisects the outer cylindrical surface, creating an upper cylindrical surface and a lower cylindrical surface. The outer top surface has an inner side. The upper cylindrical surface is orthogonal to, and terminates at, the outer top surface. The lower cylindrical surface terminates at a bottom opening, which is disposed distal to the outer top surface. Both the upper cylindrical surface and the lower cylindrical surface abut the flange. The bottom opening mates with the bottom piece. The outer cylindrical surface has an inner cylindrical surface, disposed oppositely. A retention lip is formed in the inner cylindrical surface in order to capture the bottom piece.
The top piece has an opening in its outer top surface, created by a continuous edge. The continuous edge traces out a plurality of lobes which are connected by a like number of rounded teeth. In other words, if there are two lobes, there are two teeth; if there are four lobes, there are four teeth. In the exemplary embodiment, the continuous edge traces out four lobes which are connected by four rounded teeth. In the exemplary embodiment, the four lobes and four rounded teeth are symmetrical and identical, but that is not a requirement. When there are four lobes and four teeth, which are identical and symmetrical, the opening in the outer top surface resembles a plus sign.
The bottom piece is comprised of a vessel, a stem, and a base. The vessel is open at the top. On the outer surface of the vessel, in near proximity to the opening, is a retention rim. The vessel opening and retention ring of the bottom piece mate with the bottom opening and retention lip of the top piece. The retention ring in the bottom piece is captured by the retention lip on the inner cylindrical surface of the top piece, joining the top piece and the bottom piece.
A piece of food can be inserted into the rounded teeth of the opening of the top piece. Preferably, the food is solid, cold, and damp, such as an apple slice, a cucumber slice, a pear slice, or a carrot slice. A wedge-shaped piece of food works best, although food with many different form factors will work, such as cross-sectional slices, vertical slices, rectangles, squares, discs, and ellipsoids. The food is pressed into the opening between the rounded teeth. This can be done from the top—from the outer top surface—or it can be done from the bottom—from the inner side of the outer top surface. In order to place food into the opening from the bottom, the top piece is separated from the bottom piece. The piece of food is inserted into the rounded teeth of the opening in the top piece from the inner side of the outer top surface. The top piece and the bottom piece are then combined so that the retention ring is captured by the retention lip. The teething child may gnaw on the food, the flange of the top piece, the stem, or the base.
The teether is ideally fabricated as two mating pieces from a rigid, inert structural plastic such as polypropylene (“PP”), virgin high-density polyethylene (“HDPE”), and Polyethylene Terephthalate (“PET”). Some materials, like acrylonitrile butadience styrene (“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 Polycarbonate (“PC”), are approved for use with food, but many parents are leery of Bisphenol-A which can leach out of PC. Polylactic acid (“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 should not leach due to saliva. Portions of the present invention can be textured or use a rubberized surface. The stem can be textured or it can use a rubberized material to improve the grip or to make it a more desirable surface for gnawing. Likewise, the flange and the base can be textured or rubberized so as to encourage gnawing. The teeth of the top piece can be fabricated from stiff thermoplastic elastomers.

The claimed subject matter improves over the prior art by providing a teether that allows a child to teeth on solid, cold, and damp food.
Looking at
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.
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
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.
As shown in
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.
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.
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.
