Benefits of technology

The patent describes a method for making water-soluble packaging that contains a bitterness agent with a specific bitterness value. The method involves creating cavities in a water-soluble film and filling them with a product. The resulting package has a bitterness value between 1,000 and 200,000. The technical effect of this invention is that it provides a more effective and consistent way to create water-soluble packaging with a bitterness value that is suitable for a wide range of products.

Problems solved by technology

One disadvantage of coating water-soluble packaging with Bitrex® is that the users of the water-soluble packaging pick up the package for dosing, and thus also come into contact with the Bitrex®.
If a user moves the hand toward the mouth after contacting the water-soluble packaging, even small quantities of Bitrex® remaining on the hand are sufficient to adversely affect the sense of taste for a few hours.

exemplary embodiment 1

[0107]For manufacturing water-soluble packaging containing the liquid detergent or cleaning agent E1, a film of type M 8630 (from Monosol) having a thickness of 76 μm was pulled by vacuum into a cavity to form a protrusion. The protrusion was subsequently filled with 30 mL of the liquid detergent or cleaning agent E1. After covering the protrusions, filled with the agent, with a second layer of a film containing polyvinyl alcohol, polylactic acid, 1,2-propanediol, and glycerin and having a thickness of 76 μm, the first and second layers were sealed together. The sealing temperature was 150° C., and the sealing duration was 1.1 seconds.

[0108]The entire outer surface of the water-soluble packaging was then uniformly sprayed on both sides with an aqueous medium containing saccharose octaacetate, using an atomizer. The quantity of saccharose octaacetate per water-soluble package was 2000 ppm. The liquid was absorbed by the water-soluble wrapping within 5 seconds.

exemplary embodiment 2

[0109]For manufacturing water-soluble packaging V2 containing the liquid detergent or cleaning agent E1, a first layer of a film containing polyvinyl alcohol, polylactic acid, saccharose octaacetate, 1,2-propanediol, and glycerin, having a thickness of 76 was pulled by vacuum into a cavity to form a protrusion. The protrusion was subsequently filled with 30 mL of the liquid detergent or cleaning agent El. After covering the protrusions, filled with the agent, with a second layer of a film containing polyvinyl alcohol, polylactic acid, saccharose octaacetate, 1,2-propanediol, and glycerin and having a thickness of 76 μm, the first and second layers were sealed together. The sealing temperature was 150° C., and the sealing duration was 1.1 seconds. The first and second film webs each contained 2000 ppm saccharose octaacetate.

[0110]In both cases, a quickly discernible, unpleasant bitter taste of the water-soluble wrapping was confirmed by a panel of 10 individuals.

[0111]After 4, 8, and...

Abstract

The patent application describes water-soluble packaging which contains an agent and a water-soluble wrapping. The water-soluble wrapping contains, at least in part, a bittering agent having a bitterness value between 1,000 and 200,000.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to water-soluble packaging containing an agent and a water-soluble wrapping. The invention further relates to a method for manufacturing water-soluble packaging.BACKGROUND OF THE INVENTION[0002]Detergents or cleaning agents are presently available to the consumer in various forms. In addition to powders and granules, these offered forms also include liquids, gels, or single-dose packages (tablets or filled pouches), for example.[0003]In particular single-dose packages in the form of water-soluble packaging containing liquid detergents or cleaning agents are becoming increasingly popular; on the one hand they meet the consumer's demand for simplified dosing, and on the other hand, consumers increasingly prefer liquid detergents or cleaning agents.[0004]Such a water-soluble pouch contains an agent and a transparent, water-soluble wrapping.[0005]A packaged cleaning agent for washing dishes is known from WO 96 / 08555 A1,...
