ABSTRACT:

The invention is directed to a baby's pacifying or feeding dummy defined in the introduction of claim
1
.
Dental caries has been shown to develop in small children during the sucking of a dummy, especially during the sleep when the secretion of saliva is poor. Therefore, it has been proposed to add an anti-caries agent to a dummy, from which the agent is delivered into the mouth of a baby. Schweiz Monatsschr Zahnmed Vol 104:8 1994 pp 946-951 describes two dummies, where tablets containing sodium fluoride, xylitol, and sorbitol have been inserted. In the first dummy, the downwardly facing surface of the mouth piece had three identical holes through which the active agent flows to an area around the teeth in the lower jaw. In the second dummy, there were two holes made in the downwardly facing surface and also two holes made in the upwardly facing surface, wherein the active agent flowed after its delivery into contact with the teeth in both the upper jaw and the lower jaw.
In both of these dummies, the anti-caries tablet is positioned inside the mouthpiece by means of a locking device situated in the opposing side of the cover piece. However, these approaches for making dummies have certain problems. The insertion of a tablet inside the dummy through the locking device is cumbersome. The locking device itself is structurally rather complicated and thus costly. The difficulty to keep the mouthpiece and the locking device clean creates problems and may lead to an unacceptable hygienic level.
An approach for making dummies has also been presented wherein the anti-caries tablet is placed in the lip-plate. This type of construction is complicated and the plate may exert pressure against the dental alveole, which is unsatisfactory in terms of its growth.
The object of this invention is to overcome the above problems and to provide a dummy, which allows a tablet or a dosage unit containing an anti-caries agent or another active agent to become associatively inserted. The invention is directed to a structurally simple dummy, which is easy to load with a dosage unit containing an active agent and which is easy to clean.
The invention is thus directed to a pacifying or a feeding dummy, which comprises an actual mouthpiece and a cover piece or parts for attaching the dummy to the feeding bottle. The actual mouthpiece comprises a piece made of an elastic material to be held in the mouth of a baby between the tongue and the palate. The mouthpiece of the pacifying dummy may be either a hollow or a solid piece. The invention is characterized in that the wall of a hollow mouthpiece or the solid mouthpiece has a void made into it for the insertion of a dosage unit containing an active agent.
