Many types of thermoplastic elastomer base materials are known for use in the oral hygiene implements of the present invention, for example, styrene-segmented copolymers. - A suitable substrate material is the base material of the base thermoplastic elastomer material used as the S-cleaning of the AQUA-deleted H DUO CLEANTM toothbrush sold by the present H. An example of such materials is the thermoplastic elastomeric material of the Thermolast KTM series (e.g., material TF 3 A AH) available from Gummiwerk Kraiburg GmbH & Co. KG, Germany, from 121838.doc 200812525. These materials are based on hydrogenated styrene block copolymers. The thermoplastic elastomer material preferably has a hardness in the range of 30 +/- 3 of Sh〇reA. Preferably, the thermoplastic elastomer material contains from 20 to 80 parts of a plasticizer. The range of plasticizer compositions (i.e., 5 to 15 weight percent of the lipophilic fragrance in the plasticizer mixture) appears to be important in optimizing the taste perceived by the user of the oral hygiene device of the present invention. of. A preferred ratio is 10 +/- 2%. For example, it has generally been found that less than 5% can be used to experience less beneficial taste, and if more than 15% is used, the taste can be undesirable. The term 'plasticizing oil' as used herein is intended to encompass all oils capable of plasticizing thermoplastic elastomeric materials. The term "oil" as used herein is intended to encompass all organic liquids having a plasticizing function, including paraffin, hydrocarbon and ester base oils. The viscosity of these oils can vary between first-class liquids and the same. For use in the head of a toothbrush, the oil must be of a non-toxic, orally acceptable type, and a suitable plasticizing oil is the so-called medical white oil. Medical white oil is a known plasticizing oil for thermoplastic elastomer materials and is preferred. Typically, a medical white oil contains a highly refined mineral oil that meets the quality requirements of British and US Pharmacopoeia. Typically, such oils are subject to the quality requirements of "Mineral Hydrocarbons in Food Regulations" 1996, (S.I. No. 1073) and United States F & D. A Regulations Nos. 178.3620(a) and 172.878.

In order to be used on the head of a toothbrush, φ less τ ́ v. The creature must be of a type that is non-toxic and acceptable for the cavity. Many such non-toxic orally acceptable compounds derived from the menthol nucleus are known. Suitable derivatives may include menthol esters (e.g., C1-5 alkanoates), ethers, and ketone derivatives in which the hydroxy group of the menthol core is partially replaced by a carbonyl group or cyclized to an ether (e.g., /' furansene. Preferably, the lipophilic aroma comprises, preferably, 20 to 35 weight percent of the mint-mixed, preferably 5 to 8 weight percent - or a plurality of cover vinegars, capped acetic acid), preferably With 40% by weight of the menthol of this alpha of 40% by weight of the menthol. An example of this material is peppermint oil. Peppermint oil usually comprises a composition: Total menthol menthone ketone capsin Mint furan usually in peppermint oil Minimum 52 weight percent 22 weight percent 5.8 weight percent 1.7 weight percent maximum 56 weight percent 30 weight percent 7.8 The weight percentage of 3.7 weight percent of the mint bite is the (RH+) _ isomer. The other component of peppermint oil 121838.doc 200812525 is the menthol derivative ^)_(+)_Pullerone. In addition to being comfortable, the scent of menthol and menthol derivatives also conveys a refreshing sensation and helps to overcome any problems with bad breath. The lipophilic aroma can be mixed with a plasticizing oil to form a plasticizer, and the mixture is then blended with the thermoplastic elastomer. Alternatively, the lipophilic aroma and the plasticizing oil may be blended separately with the thermoplastic elastomer. An oral hygiene implement having its oral hygiene element can be manufactured in accordance with any of the known processes for making the appliance. A typical manufacturing process involves co-molding an instrument from a plastic material and a thermoplastic elastomer material. In this process, the thermoplastic elastomer material used in the present invention as defined above can be co-molded by a molding process similar to the process for conventional materials. An example of this co-molding process is disclosed in WO-A-2005/084487. In another aspect of the invention, there is therefore provided a method of making a Φ method comprising a handle portion comprising a plastic material and an oral hygiene member, the method comprising co-molding a handle portion of the plastic material and a thermoplastic An oral hygiene element made of an elastomer material having a hardness in the range of ShoreA 20 to Shore A 50, and a group comprising 100 to 200 parts of a thermoplastic elastomer base material and 1 to 100 wounds The plasticizer 'the plasticizer comprises a compound of a plasticizing oil and a lipophilic aroma. The lipophilic aroma comprises menthol and/or a derivative thereof and is 5 to 15 weight percent of the mixture. This method can be generally known in other respects. Typically, the method package s first manufactures a portion of the plastic material of the toothbrush in a first shot model, 121838.doc 200812525. The portion of the plastic material thus fabricated is then enclosed in a mold cavity having a shape defining an elastic oral hygiene element. In the second shot model, the thermoplastic elastomer material is then ejected into the second mold under conditions in which the bond between the plastic material and the thermoplastic elastomer is achieved. In the technology of toothbrush manufacturing = typical plastic materials, for example, for the manufacture of Dr BESTTM Du. Pmtekt toothbrushes are made of plastic material and include polypropylene plastic material. It is preferred to provide the oral hygiene implement of the present invention in some suitable package (e.g., a blister pack). It has been found that some lipophilic aromas (specifically, substances including menthol) may adversely affect the pigments used on the package (especially blue pigments). The present invention further addresses this problem. The problem is solved by a package comprising a packaging layer having a surface on which a pigment is incorporated, and the printing material is covered by a barrier layer comprising at least one layer, the at least Each of the layers is polyvinyl alcohol and polyethylene, and the barrier layer is between the printed material and the oral hygiene device. Further provided is a product comprising an oral hygiene device as defined above, the oral hygiene device enclosed in a package comprising a packaging layer having a printed material on which a pigment is incorporated The surface of the printed material is covered by a barrier layer comprising at least one layer, each of which is polyvinyl alcohol and polyethylene, and the barrier layer is between the printed material and the oral hygiene implement. The insertion of the barrier layer between the oral hygiene element and the printed material has been found to help prevent the adverse effects of aroma on typical pigments used in the printed materials on the package. 121838.doc 11 200812525 Suitably, the packaging layer may comprise a paperboard-aluminum foil laminate in which the printed material is printed on the surface of the aluminum foil layer. Preferably, the barrier layer comprises two polyethylene layers sandwiching an intermediate layer of polyvinyl alcohol between the two layers.
