Embodiment 1

[0232] Example 1: A device according to one of the forms presented herein, comprising at least one active composition formulated as a Kappa-Carrageenan-Based Hydrogel

[0233] 3D Printing of Structures: MathMod (General Public License Version 3.0) was used to design structures comprising triple periodic minimal surface geometries. Thickened programmatically by modifying a script developed by Abderrahman Taha (TicknessGenerator-1.0 by Abderrahman Taha, Abderrahman Taha 24 / 08 / 2015, https: / / www.facebook.com / permalink.php?story_fbid=772823949501730&id=529510253833102) the surface of the structure. The file was exported and reformatted as an STL file for printing on a Formlabs SLA printer. The obtained structures were rinsed with isopropanol and then air-dried at room temperature.

[0234] Preparation of hydrogel: About 5.8 grams of kappa-carrageenan powder was slowly added to 180 grams of 18 MΩ water at 85° C. with stirring, and the mixture was continuously stirred until the pow...

Embodiment 2

[0255] Example 2: Comparison of devices according to one of the modalities presented herein, comprising at least one active composition formulated as a kappa-carrageenan-based hydrogel

[0256] 3D printing of structures: see Figure 18 , using MathMod (General Public License version 3.0) to design structures comprising triple periodic minimal surface helical geometries. The structures were 3D printed using Formlabs Clear Resin (GPCL04) in a Formlabs Form 2 printer. These structures are cylindrical, with a diameter of 50mm and a height of 50mm, without a central hole.

[0257] Eight gels were tested: two replicates of three different constructs and two controls. The three different structures are a single helix (called a helix), a thickened helix with a gradient, and a helix with a gradient filling one of the two volumes, as in Figure 18 shown. All eight samples were tested simultaneously to minimize the effect of small changes in temperature / humidity.

[0284] Example 3: A dual release device according to a modality presented herein comprising two active compositions formulated as a kappa-carrageenan based hydrogel

[0285] The following two hydrogels were formulated according to the above method:

Abstract

The present disclosure relates to the field of perfumery and more precisely it provides a device and associated consumer articles, for dispensing an active composition into the surrounding space.

Description

technical field [0001] The present disclosure relates to the field of fragrances, and more precisely to a device for dispensing an active composition into a surrounding space and related consumer products. Background technique [0002] Devices for dispensing active compositions into the surrounding space are known. Certain devices, such as those utilizing active compositions formulated as gels, shrink over time due to the gel. Such shrinkage may adversely affect the distribution of at least one active composition into the surrounding space. [0003] Therefore, there is a need for a simple and effective delivery device for active compositions that has less adverse effects on dispensing at least one active composition into the surrounding space. Contents of the invention [0004] One modality presented herein provides a device comprising: [0005] a) Main body [0006] Wherein, the main body has a volume (volume) and at least one surface, [0007] wherein the volume com...
