Safe and easy mixing Intern. Patent No. WO 2011 / 025745 A1 Applicant : JPRO Dairy International Inc., Oceanside (US) Date of application: 23.8.2010 Two products that, in order to guaran- tee that the product will have the best possible effect, must not be mixed together until shortly before appli- cation or consumption, are accom- modated in two containers that are “coupled“ with one another by means of threads. This means that none of the product can be spilt, thus altering the required mixing ratio. Containers with elastic handle recesses Intern.
