Definitions

  • the present invention relates to a self-closing valve for dispensing a flowable product according to claim 1.
  • a typical application for self-closing valves are containers in which the discharge of a flowable content by a pinch of the container.
  • An example of this are so-called squeeze bottles for personal care products.
  • the reduction in the inner volume of the squeeze bottle, caused by the user, increases the pressure in the bottle so that the product contained, for example a liquid soap, is dispensed through the valve. Due to the self-closing effect of the valve prevents unwanted leaking without this pressure increase content, even if the container is not closed with a cap and even if the product loads with its weight on the output range of the valve.
  • valve for dispensing a liquid or pasty product known.
  • the valve comprises a valve membrane which is convexly shaped towards the product.
  • the valve membrane is formed at the edge with a molded by encapsulation retaining ring.
  • the valve membrane is underlaid with a plate member.
  • the plate part is again held with spring arms, resulting in an increased construction cost for the valve.
  • Another disadvantage of this solution is that the air compensation is inhibited in particular by the plate member, so that the container must have a large restoring force.
  • valve membrane inwardly curved valve membrane
  • the valve membrane in turn has a central dispensing opening which rests on a support plate and is thereby sealed.
  • the valve diaphragm is held by a mounting flange, against which the valve diaphragm lies in a radially outer abutment region from below.
  • a pin On the support plate, a pin may be formed, which retracts in the closed position in the dispensing opening, thus allowing a reliable seal.
  • the lateral abutment region of the valve membrane can be designed so that it deforms inwardly under negative pressure, whereby an air path for the remindsaugung is released. However, such deformation requires a large negative pressure, so that the wall of the container must apply correspondingly large restoring forces.
  • WO 03/012377 A1 From the WO 03/012377 A1 is a self-closing valve for dispensing a flowable medium known. This valve is in the closed position a tight connection between an upwardly directed pin and a donor opening edge of a dispensing valve body.
  • the object of the present invention is thus to provide a self-closing valve for dispensing a flowable product, which is very simple and inexpensive to manufacture and requires only a small negative pressure for air sucking back. Besides, a good seal desired effect of the valve to safely avoid the unwanted escape even of small amounts of the flowable product.
  • a valve diaphragm for dispensing the product changes from a closed position to a dispensing position.
  • a dispensing opening of the valve membrane In the closed position, a dispensing opening of the valve membrane is closed by a stop. In the dispensing position, the dispensing opening is lifted from the stop and released.
  • the outer periphery of the valve membrane forms a circumferential edge which seals in the dispensing position against a stop ring. Between the peripheral edge and a lateral guide there is a gap through which the air can be sucked back when the container is closed by the valve.
  • a particular advantage of this invention is that at the same time a very simplified design and a significantly improved Luftgursaugung can be achieved.
  • the valve membrane can be formed by a simple plastic disc, which can be produced very inexpensively.
  • a container with a valve according to the invention need not have large restoring forces.
  • the wall of the container can therefore be made thin, so that a material-saving and cost-effective production of the container is made possible by the use of the valve according to the invention.
  • Fig. 1 shows cross-sectional views of a preferred embodiment of a self-closing valve according to the invention 01 in four phases during the transition from a closed position to a dispensing position.
  • Figure a) the Fig. 1 shows the valve 01 in the closed position.
  • Figures b) and c) of Fig. 1 show the transition to the donation position and
  • Figure d) the Fig. 1 shows the valve 01 in the dispensing position.
  • the valve is configured for mounting on a container (not shown), for example by insertion into the neck of a squeeze bottle.
  • the valve 01 comprises a circular valve membrane 02 with a circular central dispensing opening 03.
  • the valve membrane 02 has essentially the shape of a plate spring and also shows comparable spring properties.
  • the Fig. 1 the valve diaphragm 02 is shown in a position when the valve 01 is closed.
  • the valve diaphragm 02 is located with its dispensing opening 03 on a stop plate 04.
  • a round contact surface 06 formed thereby on the stop disk 04 closes the dispensing opening 03.
  • a sealing lip 07 of the valve membrane 02 lies with clearance on a journal 08 of the stop disk 04, since the journal 08 projects into the dispensing opening 03.
  • the shell of the pin 08 has the shape of a truncated cone and corresponds in a guide portion 09 of the inner surface of the sealing lip 07.
  • the shape of the valve membrane 02 is curved inwardly in the closed position shown and has except the sealing lip 07 in the form of a truncated cone.
  • the valve membrane 02 is elastically deformable, wherein a bias voltage is impressed by the truncated cone shape and the sealing lip 07, which determines the deformability.
  • the outer circumference of the valve membrane 02 is formed by a peripheral edge 11.
  • the circumferential edge 11 is in the closed position ( Figure a) on a stop ring 12 at.
  • the valve membrane 02 is held by the stop ring 12 from above.
  • a lateral movement of the valve membrane 02 is limited by a lateral guide 13.
  • the stop ring 12 and the lateral guide 13 are integrally with each other, creating a simple Production is possible.
  • the stop ring 12 and the lateral guide 13 may also be designed in two pieces.
  • the lateral guide 13 and the stop plate 04 are designed in two pieces.
  • the lateral guide 13 and the stop plate 04 can also merge into one another in one piece.
  • the lateral guide 13 is circular in the embodiment shown.
  • the lateral guide can also be designed so that it leads the valve membrane 02 only at some circumferential points or sections.
  • the stop ring 12 has an inclined cross-sectional area.
  • the stop ring 12 can also be designed perpendicular to the lateral guide 13. The circumferential edge 11 of the valve membrane 02 is located below the stop ring 12, so that the valve membrane 02 is sealed against the stop ring 12. Through openings 14 in the stop disk 04, the product or air stored in the interior of the container (not shown) can flow in the direction 16 into the region below the valve membrane 02.
  • the circumferential edge 11 of the valve membrane 02 preferably has the same material thickness as the main part of the valve membrane 02.
  • the peripheral edge 11 is not reinforced and has no special shaping, for example, by additional sealing lips.
  • the circumferential edge 11 of the valve membrane 02 simultaneously serves as an upper and lateral stop for the valve membrane 02.
  • a gap 15 is given between the lateral guide 13 and the peripheral edge 11 of the valve membrane 02.
  • the gap 15 extends in the embodiment shown circumferentially.
  • the gap may be designed in sections in other embodiments, when the valve membrane 02 is guided laterally, for example, in only a few points.
  • the self-closing valve 01 is particularly suitable for so-called squeeze bottles, in which by a manual squeezing of the bottle, the flowable product is issued.
  • the valve 01 is arranged for this purpose in the intended for the output opening of the bottle.
  • a circular mounting frame 21 which can be inserted into the opening of the bottle.
  • the valve according to the invention can also be designed as an integral part of the container.
  • the valve 01 is shown in a state when the pressure inside the container is slightly increased. This is for example given when the manual squeezing operation for dispensing a product from a squeeze bottle is initiated. However, a slightly increased pressure can also be present if, by handling the bottle, a force acts on it, without an output of the product being desired. Due to the slightly increased internal pressure, a force in the direction 16 acts on the valve membrane 02. As a result, the valve membrane 02 is slightly deformed. The sealing lip 07 is wedged in the guide area 09 due to the preforming of the valve membrane 02 with the frustoconical pin 08, so that a secure seal between the pin 08 and the sealing lip 07 is ensured.
  • valve membrane 02 Due to the deformation of the valve membrane 02, the bearing force of the valve membrane 02 is simultaneously increased on the stop ring 12, whereby the sealing effect of the valve membrane 02 is reinforced relative to the stop ring 12.
  • the inventive valve 01 thus has the advantage that small pressure increases do not lead to the output of the product. For example, during opening and while closing a squeeze bottle firmly grasp the squeeze bottle with a cap. The internal pressure in the bottle is slightly increased, but no output of the product is desired. Furthermore, as a result of the initial deformation of the valve membrane, the sealing of the valve membrane 02 with respect to the pin 08 is increased, since the sealing lip 07 is pressed more strongly against the pin 08.
  • valve membrane 02 As a result of the deformation of the valve membrane 02, its cross-sectional dimension increases, so that a sealing abutment on the pin 08 is retained. In the central region of the valve membrane 02, the seal is therefore maintained with only a slight increase in pressure, even if the membrane should stand out from the support surface 06.
  • FIG. 1 shows the valve 01, with a further increased internal pressure in the container.
  • the valve 01 is about to change from the closed position to the dispensing position.
  • the increased internal pressure causes the valve membrane 02 is deformed so that the truncated cone shape is significantly flattened. This is due in particular to the fact that as a result of the increased internal pressure, a force acts in the direction 17 on the valve membrane 02 below the sealing lip 07, which significantly raises the valve membrane 02 in this area.
  • the pin 08 is sealed against the sealing lip 07 but still.
  • FIG. d) of Fig. 1 shows the valve 01 when the internal pressure has become so large that the valve 01 is changed to the dispensing position.
  • the valve membrane 02 has, except for the sealing lip 07, achieved a nearly flat shape. In the embodiment shown, it has the shape of a very flat truncated cone, this truncated cone being directed opposite to the truncated cone shape in the closed position.
  • the valve 01 can also be designed in such a way that the valve membrane 02 in the dispensing position a truncated cone shape which corresponds to the opposite truncated cone shape of the closed position, but has a significantly lower slope. When changing the valve membrane 02 from the closed position into the dispensing position, the valve membrane 02 is thus everted.
  • valve membrane 02 causes a maximum of the force acting on the valve membrane 02 to be overcome during this inversion process. Exceeding the force maximum when everting is both noticeable and audible by the user. This improves the operating characteristics, in particular the tactile handling of the squirt bottle equipped with the valve 01 according to the invention.
  • the sealing lip 07 is clearly raised relative to the pin 08, so that a large opening between the sealing lip 07 and the pin 08 has formed.
  • the product is dispensed through the openings 14 in the stopper plate 04 and through the dispensing opening 03.
  • a directional arrow 18 illustrates the flow direction of the product.
  • the diameter of the pin 08 determines the diameter of the dispensing opening 03 and thus the flow rate and speed of the product.
  • the change from the closed position to the dispensing position occurs abruptly in the embodiment shown. This has the consequence that a squeeze bottle with a such valve 01 suddenly relaxed during this process, as soon as the impressed by the pinch pressure is reduced. At this moment, a certain amount of the product is spent.
  • the valve 01 and the squeeze bottle can be dimensioned such that the abruptly discharged product quantity corresponds to the typical consumption quantity of the product. Thus, the user can intuitively output the typical consumption amount of the product. If a larger output quantity is desired, the bottle should continue to be squeezed after the abrupt change of the valve 01 into the dispensing position. Since the maximum force has already been overcome to change to the dispensing position, it requires little effort to spend larger quantities of the product.
  • Fig. 2 shows cross-sectional representations of the in Fig. 1 shown self-closing valve 01 in three phases during the transition from the closed position into a remindsaug ein.
  • Figure a) the Fig. 2 shows the valve 01 in the closed position.
  • Figure b) the Fig. 2 shows the transition to the suction position and
  • Figure c) the Fig. 2 shows the valve 01 in the remindsaug ein.
  • FIG. 2 a first effect of the negative pressure is shown. Since the valve membrane 02 is still sealed against the bearing surface 06 on the stop plate 04 and against the stop ring 12, the negative pressure can not be compensated by incoming air and there is a slight deformation of the valve membrane 02. The valve membrane 02 therefore has a very light Buckle inwards. This curvature will not increase with an increase in the negative pressure, since the peripheral edge region of the valve membrane 02 will yield to the internal pressure.
  • FIG. 2 shows the valve 01 after the peripheral edge region of the valve membrane 02 has yielded to the negative pressure in the interior. Since the peripheral edge region of the valve membrane 02 is not supported and is not reinforced by a stiffening or a similar design, it requires only a very small force for this purpose. Consequently, by the valve 01 according to the invention an air sucking back even at a very low vacuum is possible. In this stuntsaug ein the valve diaphragm 02 is lifted from the stop ring 12 so that it is no longer sealed against the stop ring 12. Consequently, air can flow in from the outside through the resulting opening to the inside. This air flow is not hindered because between the valve membrane 02 and the lateral guide 13 of the circumferential gap 15 is given.
  • the valve according to the invention consists in the previously described embodiment of only two parts. This allows a simple and quick installation, since only the valve diaphragm must be pressed with a stamp in the mounting frame.
  • the membrane may preferably be made of silicone or a comparable soft elastic plastic, while the mounting frame may be made as an injection molded part of a stiffer plastic.
  • Fig. 3 shows a perspective view of a modified embodiment of the mounting frame 21. To better illustrate the specifics of the mounting frame, the valve diaphragm is not shown.
  • a plurality of support webs 22 are attached, which extend in the embodiment shown here, starting from the centrally arranged pin 08 radially to the inside of the mounting frame 21.
  • These support webs 22 serve primarily to stabilize the position of the valve membrane, which rests partially in the closed position of the valve on the support webs 22.
  • the support webs 22 increase the stability of the entire valve assembly.
  • Fig. 4 shows a perspective view of a modified embodiment of the mounting frame 21.
  • the essential difference from the in Fig. 3 illustrated embodiment is that instead of the support webs a plurality of support pins 23 are used, which are fixed to the stopper plate 04.
  • the support pins 23 perform the same function as the aforementioned support webs, namely the position stabilization of the valve diaphragm in the closed position of the valve.
  • other profiles may be provided within the mounting frame to control the position of the valve diaphragm and assist during the closure condition. Depending on the design and inherent rigidity of the valve membrane, a different number of support points are provided for this purpose.
  • the mounting frame including the lateral guide and the stop plate may also be integrally formed with the squeeze bottle or a similar container in a modified embodiment.
  • Fig. 5 shows a detailed perspective view of a modified embodiment of the valve membrane 02.
  • stiffening means 24 are provided in the surface region of the valve membrane 02, which for example extend radially and are distributed uniformly around the circumference of the valve membrane.
  • material weakenings can also be provided in order to promote deformation of the membrane at the corresponding locations.
  • Fig. 6 shows in a perspective detail view of a further Abwandlungs Anlagenkeit the valve diaphragm 02.
  • contour shaping means 25th provided, which protrude into the otherwise open cross-section of the dispensing opening 03 or are provided in the wall in the region of the dispensing opening 03.
  • the contour shaping means 25 are located on the outer edge of the dispensing opening 03 in the direction of flow.
  • the contour shaping means can also be displaced further inward in the flow direction, for example by profiling or partially slotting the wall.
  • Such a slit also offers the advantage that the transition of the membrane from the closed position is facilitated in the dispensing position, since in the edge region of the dispensing opening 03 a Querterrorismserver selectedung can be done.
  • valve is still covered when not in use by a cap, which is mounted in a known manner to the squeeze bottle.
