Definitions

• the present invention relates to a pacifier having a nipple and a shield with an opening in which the nipple is fixed by means of a plug, the nipple being formed from an elastic material and having an open end and a closed end, the shield having a nipple side from which the closed end of the nipple extends and a plug side from which the plug is accessible, the plug having an insertion part inserted into the open end of the nipple and an end part extending from the plug side of the shield, a ring-formed element having a central opening being arranged at the plug side of the shield, and the plug extending through the central opening of the ring-formed element so that the end part of the plug extends from the ring-formed element.
• a ring-formed element arranged at the plug side of the shield is formed by a bead of the open end of the nipple.
• This distinctly visible ring-formed element is considered an iconic design element, but it may also have various technical functions.
• the ring-formed element may provide friction and/or a support for well-known pacifier holders.
• Such pacifier holders typically include a band having a first end provided with an elastic ring and a second end having a clip for attachment to a piece of garment or the like.
• the elastic ring of the pacifier holder is used to connect to the pacifier whereby the elastic ring is stretched and fitted snugly around the plug of the pacifier.
• the elastic ring of the pacifier holder may not attach as good to the plug as when the pacifier is fitted with the ring-formed element.
• the ring-formed element may block or support a handle arranged pivotally in the end part of the plug from being able to move from side to side.
• nipple wall part of the nipple extending from the bead and through the opening in the shield is heavily compressed between the plug and the opening in the shield in order to fix the plug securely in the shield.
• the nipple is made of, for example, latex, a heavy compression of said wall part is not problematic.
• the nipple is made of other attractive materials, such as silicone, this material may not readily accept such heavy compression, and consequently, in the case of this material, the nipple wall may brake as a result of compression.
• DE 3117 348 C2 discloses an example of a pacifier having a ring-formed element formed by a bead of the open end of the nipple, wherein a wall part of the nipple extending from the bead and through the opening in the shield is compressed between the plug and the opening in the shield in order to fix the plug securely in the shield. Because the plug is only supported in the shield through the elastic wall part of the nipple, said wall part must be heavily compressed in order to securely fix the plug in the shield.
• WO 2023/169636 A1 discloses a solution similar to that of DE 91 07 347 U1 .
• ES1000890 UA discloses an example of a pacifier in which a thickened edge of the nipple is trapped in a cavity between the plug and an opening in the shield. A peripheral edge of the plug is rigidly connected to the opening in the shield and consequently, the thickened edge of the nipple is completely hidden by the plug.
• TW M624274 U discloses another variant of a pacifier in which a cap covers the opening of the shield at the side opposite the nipple.
• the cap is fixed to the shield and forms an internal plug inserted into the open end of the nipple.
• a thickened edge of the nipple is trapped between the plug and the opening in the shield and is covered by the cap.
• the object of the present invention is to provide a pacifier as mentioned in the introductory part, however, wherein the material of the nipple is at least not substantially compressed by its attachment in the shield.
• the plug is rigidly connected to the shield through the central opening of the ring-formed element, and the nipple is provided with a thickened edge being trapped in a ring-formed cavity formed between the opening of the shield and the plug.
• the thickened edge of the nipple may be fixed in the ring-formed cavity formed between the opening of the shield and the plug without any substantial compression of the material of the nipple.
• the plug may be supported directly on the shield as opposed to being supported via an elastic wall of the nipple, and therefore the plug may be securely fixed to the shield and consequently firmly hold the thickened edge of the nipple in the ring-formed cavity without any substantial deformation of the material of the nipple.
• the ring-formed element may be maintained visible and accessible, because the plug is rigidly connected to the shield through the central opening of the ring-formed element, as opposed to being connected to the shield around the periphery of the ring-formed element by forming a cap covering the ring-formed element.
• the iconic design of the pacifier is therefore not negatively affected and the technical qualities of the ring-formed element may still be present.
• the ring-formed element forms part of the nipple, a number of wall portions of the nipple connect the ring-formed element to the rest of the nipple, the wall portions of the nipple extend through respective cut-outs arranged in the shield or in the plug at different angular positions about a central axis of the pacifier.
• both the ring-formed element and the thickened edge may serve to securely hold the nipple fixed in the opening of the shield.
• the ring-formed element and the nipple may easily be mounted in the shield in one operation, thereby facilitating production.
• the ring-formed element and the nipple are formed as two separate elements of the pacifier.
• the plug may be supported directly on the shield along the entire periphery of the plug and thereby provide a secure rigid connection between the plug and the shield.
• the production of the nipple and ring-formed element, for instance by injection moulding, may be simpler due to simpler geometry of the nipple and ring-formed element.
• the ring-formed element may easily be formed of any suitable material independently of the material of the nipple, and the ring-formed element may be replaceable by other ring-formed elements having different properties.
• the ring-formed element carries an NFC-tag, an RFID-tag, or the like.
• a smart device such as a smart phone or the like.
• the ring-formed element is made of a luminescent material in order to produce a glowing effect. Thereby, it may be easier finding the pacifier during nighttime.
• the shield forms a tubular part extending from the plug side of the shield and surrounding the opening of the shield, and the plug abuts the tubular part of the shield.
• the tubular part may serve to provide sufficient space for the ring-formed cavity in order to securely trap the thickened edge of the nipple in the ring-formed cavity.
• the tubular part may also serve to provide support for the ring-formed element on an outer surface thereof.
• the tubular part of the shield has an end face abutting a shoulder of the plug.
• the plug may be efficiently supported by the tubular part of the shield.
• the end face of the tubular part of the shield may suitably be welded to the shoulder of the plug, thereby providing a secure connection there between.
• the plug has an outer peripheral face being at least substantially flush with an outer peripheral face of the tubular part of the shield.
• the ring-formed element is attached to the outer peripheral face of the tubular part of the shield and/or to the outer peripheral face of the plug.
• the ring-formed element has a first annular edge and a second annular edge being opposed to each other seen in an axial direction of the ring-formed element, and the first annular edge of the ring-formed element abuts a central part of the shield having a larger diameter than a maximum outer diameter of the tubular part of the shield.
• the first annular edge of the ring-formed element may be securely supported on the shield and the position thereof may be determined by the central part of the shield.
• the ring-formed element and the central part of the shield forms a radially outwardly open groove preferably having an at least substantially V-formed or U-formed cross-section.
• the radially outwardly open groove may serve to at least partly take up an elastic ring of a pacifier holder and thereby securely connect the pacifier holder to the pacifier, as explained above.
• the second annular edge of the ring-formed element is arranged at an axial position of the pacifier corresponding at least substantially to or being slightly above that of the end face of the tubular part of the shield.
• the second annular edge of the ring-formed element is arranged at an axial position of the pacifier corresponding at least substantially to or being slightly nearer the shield than a lower edge of the pivotal handle when the pivotal handle is directed away from the shield.
• the ring-formed element may support the pivotal handle and prevent it from rocking too much from side to side.
• the ring-formed element protrudes radially from an outer peripheral face of the plug.
• the ring-formed element seen in a radial cross-section of the pacifier, has a rounded outer face.
• the ring-formed element seen in a radial cross-section of the pacifier, has a flat inner face.
• the ring-formed element may better connect and securely attach to the outer face of the tubular part of the shield or the outer face of the plug.

• a ring-formed element 12 arranged at the plug side 9 of the shield 3 is formed by a bead of the open end 6 of the nipple 2.
• a wall part 39 of the nipple 2 extending from the ring-formed element 12 and through the opening 4 in the shield 3 is heavily compressed between slightly flexed portions 37 of the insertion part 10 of the plug 5 and the opening 4 in the shield 3 in order to fix the plug 5 securely in the shield 3.
• the nipple 2 is made of, for example, latex, a heavy compression of said wall part 39 is not problematic.
• the nipple 2 is made of other attractive materials, such as silicone, this material may not readily accept such heavy compression, and consequently, in the case of this material, the compressed wall part 39 of the nipple 2 may brake as a result of compression. According to the present invention, as described in the following, this problem has been resolved in that heavy compression of the material of the nipple is avoided.
• Figs. 2 to 7 illustrate a first embodiment of a pacifier 1 according to the present invention.
• the pacifier 1 has a nipple 2 and a shield 3 with an opening 4 in which the nipple 2 is fixed by means of a plug 5.
• the nipple 2 is formed from an elastic material and has an open end 6 and a closed end 7.

• a ring-formed element 12 having a central opening 13 is arranged at the plug side 9 of the shield 3, and the plug 5 extends through the central opening 13 of the ring-formed element 12 so that the end part 11 of the plug 5 extends from the ring-formed element 12.
• the plug 5 is rigidly connected to the shield 3 through the central opening 13 of the ring-formed element 12, and the nipple 2 is provided with a thickened edge 14 being trapped in a ring-formed cavity 15 formed between the opening 4 of the shield 3 and the plug 5. It is understood that, according to this first embodiment of the present invention, the ring-formed element 12 and the nipple 2 are formed as two separate elements of the pacifier 1.
• the thickened edge 14 of the nipple 2 may be fixed in the ring-formed cavity 15 formed between the opening 4 of the shield 3 and the plug 5 without any substantial compression of the material of the nipple 2.
• the plug 5 may be supported directly on the shield 3, i.e.

According to the present invention, the iconic design of the pacifier 1 is therefore not negatively affected, and the technical qualities of the ring-formed element 12 may still be present.
• the plug 5 may be supported directly and rigidly on the shield 3 by means of, i.e. through, another at least relatively rigid component.
• Such component may for instance by made of the same material as the material of the plug and may simply form an intermediate part between the plug 5 and the shield 3.
• the material of such intermediate part may in any case be at least substantially less flexible than the material of the nipple.
• the material of the nipple 2 may advantageously be silicone, because according to the present invention, the material of the nipple 2 is at least not substantially compressed, and therefore a tendency of silicone to break if heavily compressed may not pose any problem. Silicone is an industrially manufactured hypoallergenic, odourless, and taste-neutral material that is known for its purity. However, any other suitable elastic material may be used for the nipple, such as latex.
• the shield 3 and plug 5 may for instance be made of any suitable food-safe plastic material, such as polypropylene. Preferably, the shield 3 and plug 5 are made of a material being at least substantially less flexible or elastic than the material of the nipple 2.

• the ring-formed element 12 and the nipple 2 are formed as two separate elements of the pacifier 1, and the ring-formed element 12 may therefore be formed of any suitable material independently of the material of the nipple 2.
• a plastic material with a surface providing some friction may be preferred in order to better hold an elastic ring 33 of a pacifier holder 31 around the plug 5 as further explained below.
• the ring-formed element 12 is made of a material matching the appearance of the nipple 2, and it may therefore be preferred that the ring-formed element 12 is made of the same material as that of the nipple.
• the ring-formed element 12 may also be made of the same material as that of the shield 3 or the plug 5.
• the colour of the material of the ring-formed element 12 may be the same as or may be different from that of the material of the nipple.
• the ring-formed element 12 may function as an indicator ring. Thereby, it may be possible to show for example the size of the pacifier or the nipple type of the pacifier. For instance, a white ring may indicate that it is a size 1 and an orange ring may indicate that it is size 2.
• the ring-formed element 12 and the nipple 2 are formed as two separate elements of the pacifier 1, it may also be possible for the user of the pacifier 1 to change the ring-formed element 12 of the pacifier 1 according to taste.
