Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refill tube structure, particularly a refill tube structure for toothpaste or similar relics, and more particularly for use in combination with a toothbrush. The present invention relates to a miniaturized tube structure adapted to accommodate paste-like and/or liquid dentifrice.

A variety of highly compact and self-contained pocket toothbrushes are known and widely available commercially. these are,
It is generally combined with a small tube containing either liquid or solid dentifrice.

Additionally, these tubes are small and generally contain only a few convenient doses, which causes the dentifrice contained therein to be quickly consumed. The user would then have to combine the toothbrush with a new tube filled with dentifrice.

For this reason, spare filling tubes are used because known tubes are of a type that is discarded once their contents are consumed. This has the disadvantage that, on the one hand, the user has to carry a spare filling tube, and on the other hand, when the dentifrice tube is used up, it has to be replaced with his own spare. the current,
Such miniaturized tubes are difficult to find, especially in rural areas or small towns.

Additionally, miniaturized tubes are typically filled with dentifrice of varying quality and are not produced by leading manufacturers, typically forcing users to choose from a wide range of dentifrice products. situation.

OBJECTS OF THE INVENTION It is an object of the present invention to provide, in particular, dentifrices which are refillable, i.e. when the dentifrice runs out, fresh dentifrice can be introduced in a simple and very quick manner. Another object of the present invention is to provide a tube structure for a similar device.

To the above object, the importance of the present invention is to provide a refillable tube structure, in particular for dentifrice or similar products, which can be used as a miniaturized tube for pocket toothbrushes. . This configuration allows the user to introduce the desired dentifrice and/or preferred dentifrice and remove the dentifrice from a conventionally sized pasty dentifrice tube into the tube upon consumption of the dentifrice contained in the tube. The toothpaste can be immediately refilled with a certain amount of fresh toothpaste.

Another object of the present invention is to provide a miniaturized refill tube structure for dentifrices or the like that can be manufactured at a competitive cost, particularly from readily available commercially available materials.

According to the invention, the above-mentioned objects and these and other objects which will become apparent below are achieved by a refill tube structure, in particular for dentifrices and similar products. The tube structure is characterized by comprising means for combining a tube body and a pocket toothbrush, the tube body having a take-out outlet means at one end and a refill inlet means at the other end spaced apart from the one end. It is.

Further, the characteristics and advantages of a refillable miniaturized tube structure adapted to be combined with a pocket toothbrush, particularly for dentifrices or similar products, are described with reference to the accompanying drawings showing preferred embodiments.

Figure 1 shows the refillable miniature tube structure of the present invention.

In FIG. 15, the tube structure of the present invention is generally designated by the reference numeral l. In this tube structure 1,
A brush element 20 of the known conventional pocket toothbrush type is incorporated. The connection between this brush element 20 and the tube structure 1 is at the enlarged bottom end 21 of the brush handle 22.
and a base hole 23 formed in the enlarged bottom end 2, which is achieved by inserting the end of the tube structure l into said hole 23. Or tube structure 1
The hole may be closed at one end to act as a seat for frictionally engaging and receiving the end of the hole.

FIG. 2 shows an enlarged view of the miniaturized refillable tube structure of the present invention. As can be seen from this figure, the tube structure I of the invention comprises a tube body 1' having an externally threaded neck-like open end 2, for example a device made of a flexible plastics material. This neck-shaped open end 2 forms a removal outlet, which neck-shaped open end 2 forms a removal outlet which is closed by a quick stop element 3 . This quick stop element 3 also has an internally threaded nand-forming part 3', for example preferably made of a hard plastics material and adapted to be screwed onto the necked open end 2, with an externally threaded The open end 2 is sealed by screwing.

According to this invention, the other end portion 4 of the tube body 1'
a is opened, and the open end is removably tightened and closed by another covering element 4, which is screwed, for example. For this purpose, a suitable thread forming part 5 is provided on the outer surface of the other end of the tube body 1', and is adapted to engage with a thread 6 provided on the inside of the covering cord 4.

The tube structure of the invention thus differs from those previously known in that both ends of the tube structure are open and closed by respective stopper elements 3 and 4. As shown in the figure, the bottom end, ie, the part filled with paste dentifrice, has an opening that is sufficiently larger than the end where the removal outlet 2 is formed with respect to the tube body.

The method of using the tube structure of this invention is fully clear from the foregoing. In particular, the miniaturized tube structure of the present invention can be filled through the bottom end 4a during the manufacturing stage, and the paste or liquid dentifrice can be taken out from the outlet 2 by simply squeezing the tube structure 1. be able to.

When the dentifrice runs out, the user can easily refill it by unscrewing and removing the stopper element 4 and introducing fresh dentifrice of the desired type extracted from a standard-sized conventional known dentifrice tube. It can be performed.

As explained above, the object of the invention is achieved.

The miniaturized refillable tube structure is particularly intended for toothpastes or similar products, combined with a pocket toothbrush, and ready for immediate filling at the manufacturing stage. It can be refilled with any type of dentifrice desired by the user.

Of course, the tubular structures of embodiments of the present invention are manufactured from a particular material and to a particular geometry, and the preferred material is a flexible plastic material, which may be modified in various ways as desired. .
