Definitions

  • the present invention relates to a valve for a refill container (liquid container, e-liquid container) with which the liquid (e-liquid) used in an electronic cigarette (e-cigarette) can be refilled.
  • the invention relates to a dropper with the valve, a refill container with such a dropper insert and to the use of the valve in a dropper insert and to the use of the dropper insert in a refill container.
  • This refill container for an e-cigarette should be as child and tamper-proof.
  • the refill container is shatterproof.
  • the refill container according to the invention should allow a smooth refill.
  • the present invention provides a valve adapted for use in a dropper insert of a refill container for an e-cigarette, the valve having at least one valve lip.
  • the valve is designed as a silicone plate, particularly preferably as a silicone plate with a thickness of 0.3 to 0.7 mm.
  • the valve according to the invention described here preferably has a cross slot.
  • the present invention further provides a dropper insert for a refill container for an e-cigarette, the dropper insert comprising a valve according to the invention as described in this specification. It is preferred according to the invention that this dropper insert comprises an insert section for use in a refill container for an e-cigarette and an outlet section with a smaller diameter than the diameter of the insert section.
  • the valve is arranged at the lower end of the insert section. In another preferred embodiment, the valve is arranged in the transition region between insert section and outlet section.
  • the invention provides a refill container for an e-cigarette, wherein an in accordance with the invention explained in this description dropper insert inserted into the neck of the refill container.
  • the dropper insert is glued to the neck of the refill container, and it is particularly preferred that a light-curing, food grade adhesive forms the bond.
  • the invention provides a use of a valve according to the invention in a dropper insert for a refill container of an e-cigarette and a use of a dropper insert according to the invention in a refill container of an e-cigarette.
  • a valve adapted for use in a dropper insert of a refill container for an e-cigarette, the valve having at least one valve lip.
  • an improved leakage safety for e-liquid containers is achieved.
  • the valve should be designed in such a way that the regulatory required leakage safety of e-liquids is guaranteed.
  • the viscosity of conventional e-liquids plays a role.
  • the valve according to the invention is adapted so that it can be used in a dropper insert of a refill container for an e-cigarette.
  • the present invention therefore more particularly relates to a silicone valve-carrying dropper for use in a liquid container (e.g., PET bottle) as a refill container for use in an electric cigarette.
  • a liquid container e.g., PET bottle
  • a silicone-based one-way valve system is attached to the underside of the dropper used, which prevents that valve remains closed without significant pressure on the plastic bottle and thus both leakage, as well as dripping when refilling prevented.
  • the valve lips open in the flow direction of the dropper and release the liquid. The suction that acts on the pouring spout when the pressure is released ensures immediate flow stop and is therefore leak-proof by definition.
  • a plastic plate is used as a valve, for example made of rubber or silicone, with silicone being preferred.
  • the thickness of the valve plate is variable.
  • the necessary minimum pressure can vary due to the variable thickness of the valve plate, in particular of a silicone valve plate.
  • the material thickness of the valve plate, in particular a silicone valve plate can be increased in such a way that the valve opening is possible only with considerable pressure of an adult. This would not only create a leakage protection, but also another child safety feature.
  • this is an approximately 0.5 mm thick silicone plate, which corresponds in diameter to the lower inlet opening of the dropper used and is glued as an inner closure in front of the inlet opening.
  • the preferred silicone platelet has at least one, preferably at least two passage slots, in particular two passage slots arranged in a cruciform manner, which open to pressure in the direction of flow and automatically close when the pressure drops.
  • An example of such a preferred embodiment is that shown in U.S. Patent Nos. 4,378,355 Fig. 2 shown silicone valve in cross-slit double version.
  • Other embodiments are also conceivable, wherein it must be ensured that the valve has at least one, preferably two or more, for example three, and particularly preferably four valve lips.
  • designs with star clipping are also included according to the invention, eg embodiments with 6 or 8 lips.
  • valves This basic type of valve is used in the prior art, for example in ketchup bottles. Such a valve is in the Fig. 3 shown. However, such valves are not adapted for use in a dropper insert of a refill container for an e-cigarette. Neither the dimensions of these known valves nor their leak-tightness corresponds to the requirements of a valve, which according to the invention should be used in a dropper insert of a refill container for an e-cigarette. So these valves are typically oversized. In addition, the valve lips are not tuned to the retention of e-liquids for e-cigarettes, since eg ketchup regularly has a different viscosity than such e-liquids. Furthermore, the known valves are not designed to meet legal requirements for refill containers for e-cigarettes, especially those in the directive 2014/40 / EU made specifications.
  • valves known from eg ketchup bottles are not used in a dropper insert of a refill container for an e-cigarette.
  • a dropper insert is in Fig. 4 shown.
  • the exemplified dropper insert consists of two merging sections, namely an insert section in the lower region and an outlet section in the upper region.
  • the dropper section is radially symmetrical about the dashed center axis.
  • the insert section is used to insert the dropper insert into a refill container for an e-cigarette and is slightly conical in the lower quarter in the region of the outer wall.
  • the base of the outlet portion is formed perpendicular to the insert portion and provided in the upper portion with a rounded outer periphery.
  • the outer diameter of this annular base is 10.6 mm and thus slightly beyond the outer diameter of the insert section.
  • the entire dropper insert is designed as a hollow body, so that liquid can emerge during the refilling from the lower portion of the insert portion through the outlet portion, so as to accomplish the refilling operation.
  • a valve according to the present invention is inserted into the dropper insert. Conveniently, this valve may be inserted at position A or position B, as shown in FIG Fig. 6 is shown. In the position A there is the advantage that less material is needed for the valve, which contributes to cost efficiency, especially in mass production. In the position B there is the advantage that the valve does not have to be inserted through the insert portion inside to be brought into the position A. Instead, the valve may simply be applied to the lower outer end of the insert portion during manufacture. This simplifies the manufacture of the dropper insert with the valve as a whole and reduces the rate of potential production errors.
  • the valve according to the invention is designed as a silicone plate. Due to the radial symmetry of the dropper insert, this silicone plate is circular. Furthermore, according to these embodiments, the silicone valve is provided with a cross slot, so that a total of four valve lips are formed, which allow the desired tightness at rest and the desired permeability during refilling. For the dimensions of the dropper insert indicated in the figure, a thickness of the silicon wafer of 0.5 mm has been found to be particularly suitable.
  • an embodiment of the valve according to the invention is advantageous as plastic platelets, in particular as silicone platelets.
  • plastic platelets in particular as silicone platelets.
  • silicone platelets it is advantageous for achieving the desired effects with regard to leakage safety and non-spill refilling of an e-cigarette if the thickness of the platelet is 0.3-0.7 mm, more preferably 0.4-0.6 mm, and in particular preferably 0.5 mm.
  • valve according to the invention in a dropper insert or dropper, which in turn is inserted into a refill container for an e-cigarette, forms a further component of the invention.
  • the tamper resistance of such refill containers containing e-liquids is important in this context.
  • the use of light-curing, food-safe adhesives is preferably used according to the invention.
  • the leak-proof dropper Before the leak-proof dropper is pressed into the bottleneck in the production line, they are provided on the outer edge with light-curing adhesives, which can be activated by infrared radiation and thus seal the container tamper-proof.
