Abstract

The toothbrush for single use is created so that the holder (2) and head (3) of the toothbrush (1) are with the same circular cross-section and that the holder (2) is equipped at the free end with coaxial recess (5) where the toothpick (6) is inserted. The head (3) of the toothbrush (1) is rounded at the end and equipped with spirally arranged hair (4) in the same length. The head (3) of the toothbrush (1) is equipped with spirally arranged hair (4), which is shorter towards the rounded end. The head (3) of the toothbrush (1) is equipped with spirally arranged hair (4), which is longer towards the rounded end. The head (3) of the toothbrush (1) is equipped with hair (4) which is arranged in three parallel lines, equally distributed around the circumference and alternately offset. The head (3) of the toothbrush (1) with part of the holder (2) is inserted in the tubular case (8), where it is secured against displacement with at least two transversal ribs (7) placed on the holder (2) and fitting into corresponding slots (9) in the case (8) and that a space inside the case (8) marked off with the blind end and slots (9) is filled with toothpaste (11). The flat clip (10) with coarsened surface ties up with the blind end of the case (8).

Description

Disposable toothbrush

Technical field

The technical solution relates to a disposable toothbrush with a toothpaste container.

BACKGROUND OF THE INVENTION

Most toothbrushes, whether or not combined with toothpaste containers, are designed for extended use. WO 95/17116 discloses a disposable toothbrush of a simple conventional shape with conventional bristles, on whose free ends a dose of toothpaste is applied. The set of brushes is packed in vacuum-sealed compartments of the container. Utility model CZ 9129 describes a disposable toothbrush with a detachably mounted head and a bristle formed as a monolithic plastic cast in a protective case together with a small tube of toothpaste.

Known disposable toothbrushes are not large in themselves due to their purpose and with respect to packs in sets, but require a larger package due to the attached dose of toothpaste.

The essence of the technical solution

Space-saving is a disposable toothbrush with a toothpaste cartridge in its housing and a toothpick in its handle. Its head and handle have the same circular cross-section. The brush head, rounded at the end, is provided with bristles, preferably spirally arranged, which may be of equal length, or their length towards the rounded end of the head may be shortened, or their length towards the rounded end of the head may extend. The brush head can also be fitted with three parallel rows of bristles, evenly spaced around the perimeter and alternately offset. The free end of the brush handle is provided with a coaxial recess into which a toothpick is inserted. The brush head is inserted with a portion of the handle into a tubular housing, the blind end of which may be followed by a flat grip, preferably roughened. The brush is secured in the housing against displacement by at least two transverse ribs located on the handle, which fit into the corresponding grooves in the housing body. A portion of the space within the housing, delimited by the blinds and grooves, is filled with a cleaning agent.

The brushes may be packed either individually in airtight containers or preferably in sets such that each of them is airtightly sealed in a detachable portion of the common container.

Examples

Example 1

The disposable toothbrush according to FIGS. 1, 5 and 6 consists of a handle 2 of circular cross section, which passes into a head 3 of identical cross section, rounded at the end. The brush head 1 is fitted with spirally arranged bristles of equal length 4. The handle 2 is provided at a distance from the head 3 with three transverse ribs 7 and at its end a coaxial recess 5 is formed, into which a toothpick 6 is inserted. the handle 2 provided with three ribs 7 is inserted into a flexible blind tubular sleeve 8 provided with three grooves 9 such that the ribs 7 and grooves 9 form a lock against displacement of the handle 2. This lock also closes the part of the sleeve 8, which holds the dose For easier removal of the brush 1 from the housing 8, a flat grip 10 with a roughened surface is attached to the blind end of the housing 8.

Example 2

The head 3 of the brush 1, as shown in FIG. 2, is provided with spirally arranged bristles 4 whose length decreases towards the rounded end of the head 3. This arrangement allows better access of the brush head 3 to the oral cavity.

Example 3

The brush head 3, as shown in FIG. 3, is provided with spirally arranged bristles 4 whose length increases towards the rounded end of the head 3. This arrangement allows better access of the bristles 4 to the gaps between the teeth.

Example 4

The brush head 3, as shown in FIG. 4, is fitted with three parallel, alternately offset rows of bristles of equal length 4. This arrangement thus creates a seemingly two-level bristle shoulder surface of the brush head 3, increasing cleaning efficiency.

The disposable toothbrush, with a toothpick inserted in its handle and a detergent dose securely enclosed in its own housing, is extremely space-saving. It may be packed individually, preferably in an airtight container, or in sets in detachable portions of the common container.

Industrial applicability

Easy-to-use, easy-to-carry, disposable toothbrushes with a detergent dispenser are suitable for performing oral hygiene after every meal, especially while traveling. Their construction can be further used as cleaning tools for other purposes.
