Applicant: WFI Wärmflascheninnovation UG (haftungsbeschränkt) Filing date; 20/12/2014

The present invention relates according to claim 1 to a heat bottle washer closure according to claim 8 to a closure member for use in a heat bottle safety closure according to claim 7 on a manual actuator for use in a heat bottle washer closure according to claim 9 on a hot water bottle with a heat bottle closure according to claim 1, according to Claim 10 to a computer program product and according to claim 11 to a manufacturing method.

The first plastic or rubber hot water bottles existed since the 1920s. (Http://en.wikiDBdia.0rg/wlkl/W%C3%A4rmflaacha#Gaachif: htBl) Since then, the product hot water bottle has spread so much that almost everyone Household has a copy.

The spread of the hot water bottle is explained by e.g. in that it is suitable for many applications and therefore represents an enrichment for many people. Thus, hot water bottles are e.g. in case of illness, malaise or local tempering of body parts, especially in case of tension. Furthermore, the heat given off by the hot water bottle often has a calming effect. Hot water bottles are usually filled with very hot to boiling water, although nearly every hot water bottle has a British standard BS 1970: 2012, indicating that no boiling water should be added. Hot, especially near-boiling, water can cause severe scalds on contact with human or animal skin that can cause permanent damage. In the case of an unwanted opening of the hot water bottle, the water held therein can escape and thus scald the human or animal skin. Hot water bottles are a very salvaged mass-produced product that sells many millions a year, which already shows that considerable resources have been and will be used to improve hot water bottles. Furthermore, a very large number of industrial property rights have already been published, reflecting the intensive involvement with the object "hot water bottle". Thus, for example, GB230731A and EP0960608A2 devices for easier opening of sealed hot water bottles. In this case, a further device is arranged above the hot-water bottle closure. The further device in this case represents a lever element, by which an extension of the lever arm acting on the closure is formed, whereby the forces required to open the hot water bottle decrease due to the lever arm extension with the increasing lever arm. In EP0960608A2, it is considered that the Opening a hot water bottle cap required force increases by cooling the hot water bottle. However, this also means that a recently filled with hot water and only slightly cooled hot water bottle can be opened easily. Basically, the publications GB230731A and EP096060BA2 disclose the

Standard closures are a child or a demented person by applying force on the arranged on the closure element for manual contact unintentionally open the hot water-filled hot water bottle. Further, the publications DE19900197C2, DE 1906634U, DE1842006U, DE1645057U, DE163882011, DE611569A, DE552591A, DE552930A, DE487404A, GB157173, WO2012 / 136535A1, GB496452, GB105735, GB160712, GB225915, GB227345, GB245968, GB246764, GB304903, GB604341, GB385822, GB1094364 disclose Hot water bottle closures designed to increase safety or comfort when using a hot water bottle.

Nevertheless, none of the aforementioned objects could provide a solution that reduces burn injuries due to the use of a hot water bottle. For example, the homepage www.paullnchen.de - an initiative for burnt children - can be found in the use of hot water bottles: "Only fill water at 60 ° Celsius in hot water bottles and close well" (see http: // www. paulinchen.de/flleadmln/content/2012 Downloads / Dangers ln Kueche und Ba d.odf Taken on 18.12.20141. As is well-known, "good sealing" is always understood to mean closure with great force, but playing children or demented persons can unconsciously or By accident, such closures are actuated, thereby unscrewing the cap, allowing the hot water to escape from the hot water bottle Due to the large opening diameter of more than 16 mm, in particular, more than 16 mm, the heat loaded in a hot water bottle can be quickly removed from the hot water bottle emerge, which very quickly substantial Körperoberflächentelle the person using the hot water bottle is injured or scalded n can.

Furthermore, a trend to ever larger elements for manual contact is recognizable. The increasing size of the elements for contacting dogs supports a low-force watertight sealing of the hot water bottle and a low-force opening of the hot water bottle. The elements for the manual contacting of hot water bottles have widths of more than 3 cm or more than 4 cm or more than 4.5 cm.

Since hot water bottles are also handed out to children or demented persons, there is a risk that these persons will open the freshly filled hot water bottle and become scalded by leaking water. In particular, people with dementia can often apply great forces or remember the function of the hot water bottle connection and then actuate it.

It is therefore an object of the present invention to provide a heat bottle safety closure which solves the aforementioned problem.

The above object is Erflndungsgemäß by a multi-part hot water bottle safety closure, in particular for preventing unauthorized opening of a hot water bottle by third, according to claim 1 lüstüst.
