Definitions
- the invention relates to a closure of the outflow opening of a liquid container with an automatically operated opening system at a minimum temperature.
- the invention relates to a package with a temperature-dependent opening system, with the aid of which the product contained in the package can be released automatically when the respective switching temperature is reached.
- the liquid container can in particular be a package, the content of which is to be released in the course of a program.
- the invention is applicable to containers of so-called dishwasher care personnel, with the aid of which during the main wash cycle, that is to say after the pre-wash cycle, the inside of the machine is cleaned of deposits and food residues of all kinds and which is also suitable for cleaning the machine seals.
- the cleaning agent is a liquid product, which takes effect in the empty dishwasher when the normal washing program is completed and should be used once or twice a year for machine maintenance.
- the invention has for its object to provide a closure for a liquid container, which can be opened automatically without the aid of complex electromechanical components of a program circuit in a specific phase of a predetermined program characterized by exceeding a minimum temperature.
- the solution according to the invention is characterized by a stopper made of material which melts when the minimum temperature is exceeded. The outflow opening blocked below the minimum temperature is therefore released when the minimum temperature is exceeded and the plug melts.
- the packaging according to the invention with an automatic opening system is basically suitable for accommodating all free-flowing products.
- the type and composition of the materials of the stopper that melt at a defined temperature for the opening system depends on the liquid accommodated in the respective container and its application temperature. Below that due to the material composition of the The specified melting temperature stops the liquid in the packaging and is protected from surrounding media. An early release of the liquid is thus reliably avoided with the type of closure according to the invention.
- the stopper can be adjusted to any defined melting or softening point by mixing paraffins, melt waxes, polymers etc. with different melting points.
- a fusible seal produced in this way can be integrated, for example, into a screw-on or plug-on sealing cap or into the packaging itself.
- several openings can each be provided with a melt lock according to the invention.
- the melting plug should preferably consist of a material which does not interact with the contents of the packaging to be sealed.
- the invention achieves that the seals to be treated can be cleaned by hand with a cleaner packaging and then in a normal washing process, preferably with an empty machine, by inserting the packaging into the
- the rest of the packaging content must be released to the machine before the start of the washing program after a predetermined time or in a specific phase of the program characterized by exceeding a minimum temperature.
- the latter application can also be carried out on its own (with a full package if necessary).
- the product feed can only be carried out in the main rinse cycle or cleaning cycle, ie. H. after the pre-rinse cycle has ended, without any external control being required. Only in terms of packaging technology is it therefore possible to automatically open the closure according to the invention at a certain preselected point in time of a program.
- closures shown schematically in FIGS. 1 to 3 in section and in plan view each consist of a closure cap 1, a seal 2, one or more sealing plugs 3 according to the invention, in particular of a paraffin, and optionally one or more protective foils 4.
- a cut mark 5 is also provided.
- the intention was to release a liquid product in a dishwasher only in the cleaning cycle at a temperature of above 40 to 45 ° C.
- the closure shown schematically in FIG. 1 was used to solve the problem.
- the cap was cut off above the cut mark 5 and, after the closure cap 1 had been removed from the respective container, the protective film 4 was removed from the inside of the stopper 3.
- a plug 3 was a Parsffin wax with a defined melting point of 42 ° C in the exit of the Ver end cap 1 used. The experiment showed that the plug had melted about 1 to 2 minutes after the temperature had reached 42 ° C.
- the product in the upside down bottle could leak inside the machine to be treated.
- a protective film 4 can be arranged at the lower end of the stopper so that leakage of a melted stopper into the interior of the packaging is also ruled out.
- the plug 3 of FIG. 2 or the plug of FIG. 3 can be covered on both sides with protective films 4 before use. Immediately before insertion into the application area, care is taken in any case that - by pulling off the respective film 4 or by cutting along the cut cap 5 - the plug 3 is exposed on both sides. Below the melting temperature, the respective packaging then remains blocked with the closure cap 1 attached. Only when used deliberately and when the respective melting temperature is exceeded does an automatic opening occur and the contents of the packaging can come out without further action.
