Problems solved by technology

The present inventors have realized that simply placing the effervescent tablet in any prior art filled straw does not solve this problem, as the effervescent tablet is no longer stable once the packaging of the straw is opened, but consumers tend to Expect to consume beverages over an extended period of time, or use the same straw more than once
Also, if an effervescent tablet sinks to the bottom of a straw immersed in liquid, it dissolves too quickly
However, if the tablet floats in the liquid, it will rise to the top of the straw, causing inconvenient foaming near the user's mouth

Embodiment Construction

[0030] Figure 1a A first preferred embodiment of the drinking straw 1 according to the invention is shown schematically. According to the illustrated embodiment, the straw 1 comprises a first tubular end 1a, a second tubular end 1b, an elongated tubular container portion 1c, a first branch 2a connecting the first tubular end 1a to the container portion 1c and A second branch portion 2b connecting the second tubular end portion 1b with the container portion 1c. The straw 1 and its parts 1a, 1b, 1c, 2a, 2b are defined by a plastic wall 21 having a first end 4a and a second end 4b. The first tubular end 1 a is adjacent to the first end 4 a of the straw 1 , and the second tubular end 1 b is adjacent to the second end 4 b of the straw 1 .

[0031] The first and second branches 2a, 2b each define at least two but preferably three to five parallel channels 17 (see Figure 5 ), these channels are in fluid communication with the individual channels 17a, 17b of the first and second t...

Abstract

The invention relates to a drinking straw comprising: - a thermoplastic wall having an elongated container part; - a liquid permeable closure closing said container part; - at least one effervescent tablet arranged within said container part , so that a gap remains between the inner side of the wall and the at least one tablet; - hygroscopic fillers, which are arranged on both sides of the at least one tablet inside the container portion.

Description

technical field [0001] The present invention relates to a straw for the gradual addition of an active ingredient to a liquid passing through the straw. Background technique [0002] Straws for flavoring or changing the taste of liquid passing through the straw are known. Such straws can impart different flavors (eg cocoa, fruit, etc.) to liquids such as milk. [0003] The solution is to apply the flavor to part of the straw and dissolve it when the part is submerged in the liquid. Patent application US3615595 describes such a flavored straw. In another embodiment according to US3615595, the flavoring agent is applied to the inner wall of the straw. The disadvantage of this solution is the dissolution of the flavoring agent making the flavoring effect unsatisfactory. [0004] Patent application US5094861 discloses an improved embodiment of US3615595 flavoring straw. In this context, the flavor carrier is inserted into the straw. The implementation of the straw is very c...
