Abstract: The present invention relates to dosage forms for oral administration of therapeutic formulations, adapted to provide immediate and/or sustained-release of therapeutic substances, particularly for oral administration of vitamins. There is provided a dosage form for oral administration of a vitamin, comprising: a liquid phase containing a vitamin, e.g. Vitamin C in a relatively fast release form and a solid phase suspended in the liquid phase and containing a vitamin e.g. Vitamin C in a relatively slow release form.

Abstract: A brush head, in particular a toothbrush, with a base carrier (1) formed from a soft elastic material in which connecting elements comprising separate support rings (2) separated from one another and bearing a plurality of bristle tufts (4) are embedded, each of the rings having a bristle tuft threaded through. Preferably the bristle tuft can move axially in the support ring and is supported resiliently by the soft elastic material.

Abstract: A toothbrush which comprises a handle comprising at least three longitudinally elongate flexible spines arranged at the apexes of a polygon, the space between the spines containing an elastomer material which links the spines.

Abstract: A valve actuator for a valved container containing a pressurized fluid, the actuator comprising a mounting to attach the actuator to the container, and characterized by a post-expansion chamber in communication with the outlet of the actuator in which residual fluid remaining in the outlet after use can expand, and a separate suction chamber in communication with the outlet conduit via a suction opening to suck residual fluid back toward the expansion chamber.

Abstract: An electrically powered toothbrush comprising a handle which contains an electric motor and power supply, a head part connected to the handle to be driven in motion by the electric motor by a transmission means between the motor and the oral head part. The head part is flexibly and resiliently connected to the handle such that the head part can move resiliently under pressure of the oral hygiene part against a tooth surface. The motor is moveably mounted within the handle and the assembly of motor and transmission means is pivotally connected to the handle at a pivot point between the brush head and the motor. Suitably the handle is in two parts with a flexible connection between the parts.

Abstract: A toothbrush head having an undulating surface with at least one more displaced part and at least one less displaced part and with bristles having a triangular cross section extending from a more displaced part of the bristle face.

Abstract: A brush part for an electric toothbrush in which tufts of bristles are arranged in polygons, and in which the tufts of bristles lean, either around the polygons or inwardly and outwardly, so that the tuft alignments converge and preferably cross.

Abstract: The present invention relates to therapeutic formulations based on pumpkin products, in particular to encapsulated formulations for oral administration. A product of the invention comprises a hard gelatin capsule which encloses a unit dose of a formulation which comprises at least 50% by weight of one or more pumpkin product.

Abstract: A toothbrush head comprising a mid section, a tip section resiliently flexibly connected to the tip end of the mid section, and at least two side sections each resiliently flexibly connected to the mid- or tip- section at respective points on widthways opposite sides of the mid- or tip- section.

Abstract: A process for making a toothbrush head comprising widthways adjacent sections, the process comprising the stages of first making the head in an injection moulding process with the sections relatively spaced apart from each other in a widthways direction, then secondly moving the sections of the so formed head relatively spaced closer to each other in a widthways direction. An apparatus for performing the process is also disclosed.

Abstract: The present invention relates to a therapeutic composition comprising at least one clay, at least one disintegrant, at least one lubricant and at least one binding agent, particularly wherein the at least one clay is kaolin, and in particular to a palatable clay composition in the form of a tablet, and to a process for the preparation of the therapeutic composition

Abstract: This invention relates to a process for making toothbrushes, in particular an injection moulding process.

Abstract: A toothbrush with a cleaning zone with bristles, and with a deformable element by which the cleaning zone can be adapted to the shape of the tooth surface by the cleaning force, where the deformable element comprises flexible wings tapering in a wedge shape toward the cleaning zone and with guide elements between them, at least one of the wings and/or guide element is made of a compressible elastic material.

Abstract: A toothbrush head comprising three widthways adjacent sections in which the tip end of the middle section is enlarged into a bristle-carrying tip pad, there is an intermediate bristle-carrying pad between the tip pad and the base end of the head, with narrow link regions between the pads and the intermediate pad and the handle. The sections are connected to the toothbrush handle by flexible necks. The bristle distribution of a multi-section toothbrush head is thereby optimized.

Abstract: A toothbrush head having elastomeric oral hygiene parts in the form of elastomeric strips aligned non-perpendicular to the length direction of the head. Preferably adjacent pairs of strips are linked to form a strip of “V” cross section. Preferably the head comprises flexibly linked segments and is flexibly linked to the toothbrush handle.

Abstract: A toothbrush with a cleaning zone on which tooth-cleaning elements are arranged, which are pressed against the teeth during cleaning with a cleaning force, and with a deformable element by which the cleaning zone is can be adapted to the shape of the tooth surface by the cleaning force, where the deformable element has at least a first flexible wing facing towards the cleaning zone and a second such wing facing away from the cleaning zone, and also at least one guide element, and where the first and second wings are held together moveably by the guide element. In order to provide an improved toothbrush which cleans the teeth more effectively and at the same time more gently, it is provided according to the invention that the wings form a wedge, by being connected together at one end and distanced from each other at the other end.
