Definitions

  • the first component comprises a relatively rigid or hard plastic material, which forms the bristle-bearing head, neck, inner handle or stem portion, and, optionally, the base of the brush.
  • the second component comprises a soft elastomeric material, which forms an outer gripping portion, and is injection molded over the inner hard plastic handle portion of the brush.
  • the brush is manufactured by a dual component injection molding process such that the elastomeric material surrounding the hard plastic inner handle portion of the brush may be easily substituted with other elastomeric grips of different design without the need to retool an entire dual component mold, which is quite expensive.
  • a hard plastic portion of the brush is molded in a first mold.
  • the hard plastic portion contains either voids or channels where the second, soft component is to be molded.
  • the molded hard plastic portion is then transferred manually or automatically to a second part of the mold where the soft rubber or elastomeric material is injected to fill the voids in the hard plastic skeleton and run along any molded channels where a chemical /mechanical bond holds the two components together.
  • One such process is illustrated, for example, in PCT application no. WO 94/05183 to Jordan A.S.

  • This permits manufactunng and marketing flexibility of a line of toothbrushes that can dramatically change appearance in record time. This is accomplished by first molding a hard plastic skeleton having a handle portion of smaller external diameter than the internal diameter of the soft elastome ⁇ c coating such that the hard plastic skeleton of the handle section does not penetrate the outer surface of the sott elastome ⁇ c coating. However, the hard plastic ay penetrate the elastome ⁇ c coating onlv at the base of the handle if so desired.

  • a toothbrush skeleton of the present invention made of relatively ngid plastic matenal. is designated generally as 10. It is shown in an up ⁇ ght, self- cr andmg position, although it should be understood that it does not have to ue self-standing.
  • Skeleton 10 is made up of head portion 12, which will bear the b ⁇ stles in the complete brush, neck 14, which is connected to head 12, internal handle section 16, which terminates in base 20. which permits the brush to be self-standing, a feature that is of particular interest for c dren.
  • Handle section 16 is here illustrated as of solid elliptical cross-section.
  • cross section of internal handle section 16 may be circular, ovoid, polygonal or of any other configuration, and it need not be solid but may be ⁇ bbed or hollow, or any combination of two or more of these constructions. If handle stem 16 is hollow, then a solid core, preferably metal, would be inserted therewithin du ⁇ ng the second injection molding cycle to support its integ ⁇ ty du ⁇ ng this second cycle Base 20 is an optional va ⁇ ant and is not needed to practice the present invention.
  • a complete toothbrush 18 is shown also in a vertical, self-standing position.
  • head portion 12 bears a plurality of tufts of b ⁇ stles 24.
  • Neck 14, which is connected to head 12 joins internal handle section 16 (not visible), which is covered by elastome ⁇ c g ⁇ p portion 22, the handle terminating at base 20.
  • FIG. 3A elastome ⁇ c g ⁇ p portion 22A of brush 18A is dramatically different from elastome ⁇ c g ⁇ p portion 22 illustrated in Figure 2 and from elastome ⁇ c g ⁇ p portion 22B of brush 18B illustrated in Figure 3B, which further illustrates another va ⁇ ant of the brush oi the present invenuon.
  • optional flange 25 separates neck 14 from internal handle section 16 (not visible).
  • FIG. 4 a simplified plan view ot the bottom half or "knock-out" side 26 of the mold is shown.
  • the corresponding removable cavity blocks in the upper half of the mold or the "injection ' side 28 are a mirror image of the side shown here, with the exception of the inlets for injecting the thermoplastic mate ⁇ al, which forms the hard or ngid skeletons 10, and the elastome ⁇ c mate ⁇ al, which forms the external handle portion 22 contained therein, which are standard features in the injection molding art and are not part of the invention herein.
  • Injection side 28 of the mold is best shown in Figs. 5. 6A and 6B.
  • ejector pins and other conventional features of KO side 26 are also not illustrated herein as they, too, are standard in the injection molding art and are not part of the invention herein.
  • knock-out side 26 of a 12+12 cavity mold is shown. Such a mold is capable of making 12 brushes at a time.
  • the portion of the mold 26A (illustrated here as the left side of Fig. 4) is that portion of the mold in which a molten thermoplastic mate ⁇ al is injected into each cavity

  • the balance of the mold cavities which hold base 20, neck 14, and (unbristied) head 12 of skeleton 10. remain the same and unchanged.
  • each skeleton 10 serves as the interior mold surface while each cavity 38 serves as the outer mold surface, and the elastomeric material thus fills the space created between these inner and outer mold surfaces.
  • the shape of external elastomeric handle 22 can be changed by the simple expedient of changing the shape of mold cavities 38a-381.
  • This is made relatively quick and comparatively inexpensive by utilizing removable first 32a and second 32b cavity blocks, which can easily be removed from the knock-out half of the mold, as well as corresponding removable third 32c and fourth 32d (not shown) cavity blocks, which can also easily be removed from the injection half of the mold.
  • the removable cavity block 32a is held in place by tapered wedges 40c and 40d and screws 42e, 42f, 42g, and 42h.

  • Corresponding tapered wedges and screws are present to hold the two removable cavity blocks on the injection side 28 of the mold.
  • the mold is opened, the screws on both halves of the mold are removed, the tapered wedges removed, the removable cavity blocks taken out and the new ones substituted therefor. Then, the wedges are replaced, the screws replaced and tightened and the mold is ready to manufacture the new brush design. Therefore, by replacing only that portion of the mold (i.e. the four removable cavity blocks) that forms the elastomenc external handle (since the balance of the mold cavity that forms the head 12, neck 14. and base 20 of the skeleton remains in the mold), the cost of changing from a particular brush design to a new one is greatly reduced.

Abstract

L'invention concerne une brosse à dents moulée par injection, à composants multiples, présentant généralement un axe longitudinal dans lequel une partie manche molle est moulée à une partie manche interne, et son procédé de fabrication. Un composant de ladite brosse est un corps de brosse à dents relativement rigide comprenant une tête, un col relié à cette dernière, un manche interne relié audit col et se terminant, éventuellement, au niveau d'une base qui permet à la brosse d'être autoporteuse. L'autre composant est un manche externe relativement mou. Ledit manche présente plusieurs poils placés sur la tête. Il comprend un matériau élastomère relativement mou, moulé par injection de sorte qu'il forme la partie manche externe recouvrant la partie manche interne du corps de la brosse à dents. La partie manche externe a un diamètre intérieur supérieur à celui du manche interne, de sorte que le premier composant rigide ne pénètre pas dans la section manche externe le long de son axe longitudinal. Le procédé de l'invention permet de modifier la conception du manche externe relativement rapidement et à peu de frais, lorsqu'on désire fabriquer des brosses de forme différente. Pour ce faire, on moule le corps de la brosse de sorte qu'elle ait une configuration classique et on moule les manches externes dans des blocs de moules à empreinte amovibles, qui peuvent être remplacés par d'autres blocs de formes différentes lorsqu'on désire fabriquer des brosses a manche de forme différente.
