A BOTTLENECK INSERT

Abstract

A bottleneck insert having a cylindrical body; a tube located inside the cylindrical body, wherein the tube is coaxial with the cylindrical body and extends through along the cylindrical body, end wherein the tube is connected to a side wall of the cylindrical body via a base located at a first end of the side wall of the cylindrical body; and a sieve having a form of a circular ring and located between the tube and the side wall of the cylindrical body.

Claims

1. A bottleneck insert comprising: a cylindrical body; a tube located inside the cylindrical body, wherein the tube is coaxial with the cylindrical body and extends through along the cylindrical body, and wherein the tube is connected to a side wall of the cylindrical body via a base located at a first end of the side wall of the cylindrical body; and a sieve having a form of a circular ring and located between the tube and the side wall of the cylindrical body.

2. The bottleneck insert according to claim 1, wherein the sieve has openings of a diameter from 100 to 500 μm.

3. The bottleneck insert according to claim 1, wherein the sieve is distanced from a second end of the side wall of the cylindrical body.

DETAILED DESCRIPTION OF EMBODIMENTS

[0030] FIG. 1 presents an embodiment of the bottleneck insert in a partial lengthwise cross-section in an isometric top view. The insert comprises a cylindrical body 10, in which there is located tube 12 located coaxially and extending through along the body 10, wherein the tube 12 is connected to the side wall of the body 10 by means of a base 14 which is located at one of ends 15 of a side wall of the body 10.

[0031] The insert comprises a sieve 20 in the shape of a circular ring, with openings 21, located between the tube 12 and the side wall of the body 10. The sieve 20 is located at a distance H from the second end 16 of the side wall of the body 10, forming an open mixing chamber 31 above the sieve 20 and a container 32 for the liquid between the sieve 20 and the base 14.

[0032] On the outer and on the inner peripheral edge of the sieve 20 there are recesses 23 which can engage their corresponding protrusions on the inner surface of the side wall of the body 10 and on the outer surface of the tube 12 by press fitting that improve the mounting of the sieve 20 in the body 10.

[0033] The outer surface of the side wall of the body 10 has a peripheral outer body protrusion 11, the diameter of which is adjusted to the inner diameter of the bottleneck, enabling the placement of the insert inside the neck by press fitting.

[0034] The tube 12 is further connected to the side wall of the body 10 by means of two arms 13.

[0035] On the inner surface of the side wall of the body 10 there is a peripheral inner body protrusion 17, to which the sieve 20 is adjacent and press-fit.

[0036] The tube 12 protrudes by a distance x of about 0.5 mm above the second end 16 of the side wall of the body.

[0037] As presented in FIG. 5A, in one part of the sieve the openings has a more dense distribution than in another part of the sieve. For example, as presented in FIG. 5B, in one part of the sieve the openings is larger than in another part of the sieve.

[0038] FIG. 6 presents an example of a rotatable cover 33 with an access opening that can be put on the sieve 20 from the side of the mixing chamber 31. The cover 33 has the shape of an incomplete ring, which can be rotated, covering a portion of the openings 21 of the sieve 20.
