Description

This application is the national stage (Rule 371) of international application No. PCT/EP2021/054248 filed 20 Feb. 2021.

TECHNICAL FIELD

The object of the invention is a bottleneck insert, in particular for a bottle with water.

BACKGROUND

There is a problem of diversifying a flavour of bottled water. There are known flavoured bottled waters, which however, in order to maintain a long shelf life, usually contain various preservatives.

There are known bottle caps containing a powder, which, for example, after twisting the bottle cap onto the bottle, mixes with the water contained therein, to add specific flavour to the water.

However, a noticeable change in the flavour of the whole volume of water contained in a bottle requires a considerable amount of a powdered or fluid substance, which must be contained in the bottle cap and subsequently mixed with the water.

SUMMARY OF THE INVENTION

There is a need to provide a bottleneck insert with a consumable substance which would enable limiting the amount of required consumable substance (flavouring) contained within the insert. It would be advantageous if the insert would provide satisfactory taste sensations when consuming water from the bottle.

There is disclosed herein a bottleneck insert having a cylindrical body. A tube is located inside the body. The tube is coaxial with the body and extends through along the body. The tube is connected to a side wall of the body by means of a base located at a first end of the side wall of the body. A sieve formed as a circular ring is located between the tube and the side wall of the body. Thereby, a container for liquid is formed between the sieve and the base. The container may contain a liquid, such as concentrated fruit juice.

During the consumption of a beverage from the bottle, water (or other beverage) passing across the tube can be directed by the drinking person from the bottle by proper positioning of the lips or the tongue on the sieve, through the openings of which it can come into contact with the liquid from the container (for example, fruit juice). This causes the migration of the flavouring from the liquid in the container to the water in very close vicinity of the tongue of the person drinking from the bottle, and therefore in the vicinity of sensitive taste buds. It also causes taste sensations related to the type of liquid which is placed in the container.

The tube can have an inner diameter s equal from 5 to 25 mm. The smaller the inner diameter s of the tube, the smaller the unit flow of water, and thus the higher the perceivable intensity of flavour, caused by partial mixing of water with the liquid (such as juice) present in the container.

In other words, by changing the inner diameter s of the tube, as well as the size of the openings, it is possible to adjust the desired mixing ratio of water (or other beverage) with the liquid present in the container of the insert, and, as a consequence, the intensity of flavour experienced by the user when consuming the water from the bottle with the insert according to the invention placed inside the neck.

The diameter DO of the openings of the sieve may be from 100 to 500 μm. Therefore, a dense liquid present in the container between the sieve and the base does not flow out of the insert spontaneously, even when the insert has its openings facing down.

The size of the body shall correspond to the inner size of the bottleneck such that it can be conveniently placed inside the neck by press fitting, such that the flow of liquid to the outside of the bottle is only possible via the tube of the insert. For example, the outer surface of the side wall of the body may have a peripheral outer protrusion with a diameter corresponding to the diameter of the neck, wherein the height of the peripheral outer protrusion may be smaller than the height of the whole body, so as to limit the force necessary to press-fit the insert to inside the bottleneck. The outer diameter d of the body is smaller than the diameter D of the peripheral outer body protrusion.

The sieve may be distanced from a second end of the side wall of the body, for example by a distance equal from 1 to 10 mm. A short distance allows a close contact of the mouth or the tongue with the sieve, under which there is juice, which increases the intensity of experiencing the flavour of the juice.

The end of the tube may extend above the second end of the side wall of the body, for example by a distance of x from 0.1 to 3 mm. Due to this, after press fitting the insert inside the bottleneck by tightening the original bottle cap, the end of the tube abuts the inner surface of the bottle cap, preventing the ingress of water into the mixing chamber between the tube and the side wall of the body.

The tube may be further connected to the side wall of the body by means of at least one arm, such as by two, three, four or more arms. The arms are to stiffen the mounting of the tube inside the body.

The insert may further comprise, adjacently to the sieve, a peripheral inner body protrusion on the inner surface of the side wall of the body. The peripheral protrusion constitutes a support element for the sieve, due to which the sieve is prevented from moving into the body. The sieve may be connected to the peripheral protrusion by press fitting.

The thickness g of the sieve in areas distant from the clearance of the openings can be equal from 0.5 to 1.5 mm, while the thickness G of the sieve in areas directly adjacent to the edges of the openings can be slightly larger, for example by a value of 0.05 to 0.2 mm. Larger thickness of the sieve in areas directly abutting the edges of the openings can be achieved by laser cutting to create the openings. During laser cutting, the liquefied material around the laser beam partially flows around the opening, forming peripheral protrusions around the openings.

The distribution of openings in the sieve may be regular or uneven. For example, in one part of the sieve the openings may have a more dense distribution than in another part of the sieve. This allows the user to place the mixing chamber relative to the mouth and the tongue, in a position which better fulfils the needs of the user (less or more intense mixing of water with the liquid from the container).

The openings in the sieve have equal or various sizes. For example, in one part of the sieve the openings may be larger than in another part of the sieve. This also allows the user to place the mixing chamber relative to the mouth and the tongue, in a position which better fulfils the needs of the user (less or more intense mixing of water with the liquid from the container).

A rotatable cover with an access opening may be located on the sieve at the side of the mixing chamber. This may enable the mixing of water with the liquid from the container only within a selected group of openings.

The sieve may be press-fitted between the inner surface of the side wall of the body and the outer surface of the tube to facilitate its easy insertion.

The insert is preferably made of plastic, such as polypropylene, polyamide or polystyrene, which is approved for contact with food.
