• a spray can is specified in which a more favorable production with simplified disposal or simplified recycling is realized with structurally simple means.
• the cutting tool could be coupled to a traction means, so that the cutting tool cuts into a wall of the second container by pulling the traction means relative to the first and / or second container.
• the traction means could extend from the inner region of the second container to the outer region of the first container. As a result, a simple operation of the traction means is guaranteed from outside the spray.
• the cutting tool could be arranged on the arranged in the interior of the second container end of the traction means.
• the cutting tool is thus virtually remote-controlled.
• a grip element For safe and easy operation of the opening device could be arranged on the arranged in the outer region of the first container end of the traction means, a grip element.
• the grip element could be arranged on a base coupled to the traction means. This ensures a secure operative connection of the grip element with the traction means.
• the grip element could be annular.
• the gripping element could furthermore be arranged in a groove formed in the base and be pivotable in this groove.
• the traction means could be rotatable about its longitudinal axis.
• a rotation of the arranged at the end of the traction means cutting tool is made possible by virtually 360 °. This allows a slicing of the second container along its entire circumference.
• the traction means could be formed as a rod or pin. As a result, a particularly secure transmission of a rotation of the traction means is ensured on the cutting tool.
• the traction means could extend through a bottom of the first and / or second container.
• a guide element for the traction means through which the traction means extends therethrough.
• the guide element could be designed in the form of a sleeve.
• a sliding surface having guide for the cutting tool could be arranged at the bottom of the second container.
• the cutting tool before slicing the second container could still in a kind of rest position within be arranged of the second container.
• the traction means could be pulled outwards.
• the cutting tool could be erected during the pulling of the traction means by sliding along the sliding surface in the direction of the wall of the second container or be erectable.
• the cutting tool could pierce the wall of the second container or cut into the wall of the second container. Only then is the cutting tool brought into an active position.
• the traction means could be rotated by more than 360 °, so that a complete separation of a part of a second container is made possible by a remaining remainder of the second container.
• the user of the spray can feel this state of the completely separated part of the second container due to the lower resistance when turning the traction means, since the cutting tool in this state no longer experiences cutting resistance.
• the cutting of the second container is thus effected by a combined movement of a pulling out of the traction means in the direction of the longitudinal axis of the traction means and a rotation of the traction means about its longitudinal axis to the desired extent. These two movements can be performed consecutively or simultaneously.
• an embodiment of the guide for the cutting tool substantially as an annular disc is particularly favorable. It does not matter in which rotational angle position the cutting tool is just when cutting into the wall of the second container.
• the sliding surface could be inclined in a particularly practical manner to the longitudinal axis of the traction means, whereby a particularly safe erection of the cutting tool is realized.
• the sliding surface could for this purpose be formed substantially conically along the circumference of the guide or the annular disc.
• the cutting tool is substantially freely rotatable along its circumference after the second container has been completely cut open.
• the cutting tool could be designed as a knife with preferably a tip and with respect to the tip on both sides arranged cutting edge.
• the cutting tool could be formed for cutting the second container along its entire circumference.
• the stability and strength of the cutting tool should be selected to be correspondingly high.
• the region of the wall of the second container provided for slicing the second container could be designed to be weaker than other regions of the wall of the second container.
• the region of the second container to be cut open could be designed as a type of predetermined breaking point, which facilitates the cutting by means of the cutting tool.
• the cutting tool could have a single knife in a particularly simple embodiment. However, it could also have, for example, two blades which protrude in opposite directions radially from the traction means. Specifically, the blades could be offset from each other by an angle of 180 ° with respect to the longitudinal axis of the traction means. This would have the advantage that the complete slicing of the second container along its entire circumference is realized already after a rotation of the traction means by a rotation angle of 180 ° would. Accordingly, the cutting tool could also have more than two blades, which could be arranged at the same angular distance from each other. In such an arrangement, for example, three or four knives, then a rotation of the traction means by 120 ° or 90 ° could be sufficient to ensure complete cutting of the second container along its circumference.
