Definitions
- the invention relates to a pump dispenser and its cap unit. It is particularly, but not exclusively, about dispensers designed to dispense nicotine-containing liquids as smokers' substitutes.
- dispensers according to the invention are preferably not refillable.
- the object of the invention is to provide a pump dispenser which, with low production costs, permits a secure possibility of closing and easy opening.
- a pump dispenser for dispensing liquids in atomized form which has a liquid reservoir with a removal opening for receiving the liquid before dispensing and a pump device attached thereto.
- the liquid reservoir can be formed by a one-piece body. However, it can also have an outer shell and an inner receptacle, such as a bag, separately.
- the volume of the liquid reservoir is preferably comparatively small, since the dispenser should be able to be carried in a trouser pocket in many preferred fields of application.
- the liquid reservoir can preferably hold a maximum of 100 ml, in particular a maximum of 50 ml. Significantly smaller liquid reservoirs with a maximum capacity of 20 ml or less can also be useful.
- Liquid can be conveyed from the liquid reservoir to a discharge opening via an actuating pusher that can be depressed downwards in a main direction of the pump dispenser.
- the discharge opening is preferably integrated into the actuation button and is preferably perpendicular to the main direction defined by the direction of actuation.
- a pump device for a pump dispenser according to the invention usually has a pump chamber, the volume of which can be reduced by depressing the actuating pusher and which is connected to the liquid reservoir via an inlet channel.
- a pump device according to the invention has an outlet channel leading to the discharge opening, in which an outlet valve is provided, which is mechanically opened directly by pressure upstream or by pressing down the actuating button.
- the pump dispenser has a cap unit with a base element attached to the liquid reservoir and with a cap element that can be pivoted relative to the base element due to a joint.
- a one-piece component made of plastic is preferably provided, which forms the base element and the cap element or essential parts thereof in one piece, the joint between them also being formed in one piece therewith and preferably as a film hinge.
- the base element surrounds an inner area in which part of the pumping device is arranged.
- the actuating pusher of the pump device preferably protrudes through this area in order to be able to be actuated when the cap unit is in the open state.
- the cap element In a closed state, the cap element covers the actuating button and the discharge opening and thus forms a protection against dirt penetrating from the outside and/or against residual liquid escaping from the interior of the cap.
- the cap member When opened, the cap member exposes the actuating button and the discharge opening.
- Pump dispensers according to the invention are intended in particular for purposes in which people carry them with them in everyday life, in particular as pump dispensers for liquids containing nicotine or cannabis or as dispensers for hand disinfectants.
- the cap unit has, opposite the joint, a holding device for securing the closed state of the cap element, which has a first holding contour on the side of the base element and a second holding contour on the side of the cap element. contour features.
- the holding contours which face one another in the closed state, engage in one another and in particular bring about a form-fitting coupling.
- a release surface on the outside which is particularly preferably highlighted by color or, in particular, a haptically detectable shape, and by means of which the holding contour of the base element can be displaced at least in sections and, in particular, can be pressed in radially, in order to be able to cancel the in particular form-fitting coupling that the cap element can then swing open or, depending on the design of the cap unit, springs open automatically.
- the retaining contours are preferably designed in the form of an inside recess or an opening on the side of the cap element and an outwardly pointing engagement extension on the side of the base element.
- the engagement extension is deflected radially inwards by means of the release surface. In the closed state of the cap element, the engagement extension is positioned in the depression or in the opening. This leads to a form-fitting coupling which preferably cannot be opened in a non-destructive manner without prior deflection of the release surface.
- the holding device is to fulfill the function of a child safety device, it is preferably provided that the cap element cannot be opened non-destructively or destructively with a tensile force of less than 30 Newtons without deflecting the release surface.
- At least one of the holding contours preferably has an insertion bevel, so that by closing the cap element the holding contour on the base element is deflected inward and finally jumps into its latched position.
- the second construction which can be combined with the first described, provides that the holding device has a downward-pointing lifting surface on the side of the cap element.
- a protective section is provided on the side of the base element, which covers the lifting surface when the cap element is closed and thereby the cap element Pivoting vertical and upward forces are prevented, making inadvertent opening unlikely.
- the protective section is also preferably highlighted in terms of color or shape, for example provided with a profiling.
- the protection portion is designed to withstand, or at least protect the lifting surface against, vertical force application.
- the protective section can be pressed in radially as intended by means of a finger and in particular the thumb, so that the lifting surface can be gripped underneath by the finger and the lifting surface can then be pressed upwards by means of the finger.
- the lifting surface should not be sharp-edged, if possible, in order to allow easy opening.
- the lifting surface is preferably flat or only slightly convex or concave. As already described, this lifting surface is made accessible by depressing the protective section.
- the protective section is preferably sufficiently freely displaceable that it releases at least a section of the lifting surface with a width of 1.5 mm of the lifting surface through a radially aligned actuating force of 10 Newtons. On an area basis, such an actuating force preferably results in the exposure of a portion of the lifting surface of at least 10 mm 2 , more preferably at least 20 mm 2 .
- a protective section in the form of a bridge element which is molded onto adjacent sections of the base element at the end and is cut free at the side has proven to be particularly advantageous.
- Such a bridge shape provides effective protection against deformation in the direction of the lifting surface and is highly configurable to achieve a desired resistance of the protection section to radial deformation.
- the lifting surface can be formed directly by a lower edge of the cap element. However, since such an edge is usually not wide enough on its own to allow easy opening equip, it is considered preferable if the lifting surface is formed at least also by the underside of a cap region of the cap element outwardly projecting horizontal lifting web. This can be provided circumferentially, but is preferably only provided on one side on the cap element.
- the base element of the cap unit is coupled directly or indirectly to the liquid reservoir, for example via a snap connection, which preferably causes a high resistance to separation, so that children are unable to separate the entire cap unit from the liquid reservoir.
- a structural possibility provides that the pumping device is attached to the liquid reservoir by means of a crimp sleeve and the snap connection serves the purpose of securing the base element to this crimp sleeve.
- Another aspect of the invention relates to a pump dispenser, in particular of the type described, in which the crimp sleeve mentioned is dispensed with and instead it is provided that the base element is provided for direct attachment to the liquid reservoir and has a holding surface pointing in the direction of the removal opening of the liquid reservoir, by means of which the pump device is secured to the liquid reservoir, in particular is clamped between the liquid reservoir and the base element, if necessary with the addition of a sealing ring between the liquid reservoir and the housing of the pump device.
- the base element of the cap unit thus fulfills an additional function here, in that it fixes the pump device to the liquid reservoir.
- a dispenser according to the invention can therefore consist of a very small number of components in addition to the pumping device. In the extreme case, it is only a question of the liquid reservoir, a one-piece cap unit and possibly a sealing ring between the pump device and a removal opening of the liquid reservoir.
- the pumping device preferably has an external peripheral collar which in turn rests on an edge surrounding the removal opening or on a sealing ring located there. The holding surface of the base member pushes this collar towards the fluid reservoir.
- the holding surface is preferably designed in the form of an annular surface, to which a stop surface is provided opposite, which limits the mobility of the actuating pusher.
- the base element is preferably used for attachment to the liquid reservoir and as a support for the release surface described and/or the protective section described.
- the base element preferably has an inner shell, on the inside of which a clamping device is provided for fastening the base element to the liquid reservoir, and an outer shell on which the release surface or the protective section is provided.
- the inner shell can be subdivided by axial cuts into tongue sections, which latch as intended on the described crimp sleeve or directly on an outlet of the liquid reservoir distributed around the circumference.
- the cap element with a lower end edge preferably rests largely circumferentially on an upper end edge of the base element.
- this upper closing edge can run in a uniform plane, which is aligned orthogonally to the main direction of the dispenser.
- the upper closing edge has a non-uniform extension in the direction of the cap element in relation to the main direction.
- the terminating edge can extend further upwards in a joint area of the terminating edge than in an actuation area of the terminating edge over which a user grips to actuate the actuating pushbutton.
- This actuation area which is preferably offset by 90° with respect to the articulated area, thereby allows easier actuation of the actuation pusher and, overall, a shorter design of the dispenser.
- the terminating edge can also extend further upwards in a joint area of the terminating edge than in a discharge area of the terminating edge, towards which the discharge opening is directed or, in the case of a rotatable actuating pushbutton with discharge opening, can be aligned.
- the consequent lowered closing edge in the area of the discharge opening also serves to achieve a short design of the dispenser.
- the terminating edge extends further upwards in a holding area opposite the joint area than in the mentioned actuating area and/or in the mentioned discharge area of the ending edge.
- the base element and the cap element are preferably provided with interacting structures in the area of the closing edges, in particular with at least one elevation and a corresponding depression, through which the base element and the cap element in the closed sen state based on a radial direction are positively secured to each other. In particular, this facilitates the automated assembly of the dispenser and also subsequent manual handling when the dispenser is used.
- the structures preferably extend over an angle of at least 90° on the base element and on the cap element, particularly preferably over an angle of at least 120°.
- a possible design of the dispenser provides that it has a substantially rotationally symmetrical outer shape, in which case it preferably has a circular-cylindrical shape over the majority of its length, which is optionally rounded or tapered at the ends.
- the base element or the entire cap unit or the entire dispenser has an outer contour based on a projection in the main direction, which deviates from the circular shape.
- Such a base element or such a cap unit is thus flattened over its entire length, the outer contour preferably having a substantially rectangular or oval shape in cross section.
- the liquid reservoir is preferably flattened to the same extent.
- the outer contour of the base element can have a smaller extent in the direction of a discharge direction defined by the discharge opening than in a direction at right angles thereto and to the main direction.
- the joint is preferably provided on one of the short sides of the base element. This allows a particularly ergonomic operation, in which the liquid reservoir is gripped with the hand, the cap element is released with the thumb and the actuating push-button is then depressed with the index finger.
- the dispenser is preferably designed accordingly symmetrically.
- Pump dispensers according to the invention can be used as medication dispensers.
- the fluid reservoir can, for example, be filled with a painkiller such as lidocaine, which is taken orally.
- a pump dispenser according to the invention with its favorable manufacturability and its high level of safety, also with regard to child safety, but in particular with its ease of use, is particularly well suited for this area of application, since acceptance by the user is important when used as a smoker's substitute .
- FIG. 1 to 3 show a first embodiment of a pump dispenser according to the invention in the closed and open state and in a sectional view.
- FIGS. 4 to 6 show a second embodiment of a pump dispenser according to the invention in the closed and open state and in a sectional view.
- FIG. 7 to 9 show a third embodiment of a pump dispenser according to the invention in the closed and open state and in a sectional view.
- 10 to 12 show a fourth embodiment of a pump dispenser according to the invention in the closed and open state and in a sectional view.
- 13A to 13C show the operation of opening the fourth embodiment.
- 14 and 14A as well as 14B show a special design of the closing edges on the base element and on the cap element of the pump dispenser according to the invention.
- FIG. 1 to 13C show a total of four exemplary embodiments of a pump dispenser 10 according to the invention, which all have the following features.
- a pump dispenser 10 that is intended to be carried by people in everyday life, for example to carry disinfectants or a smoker's substitute product containing nicotine.
- the dispensers each have a liquid reservoir 20 with an internal volume of 20 ml, for example, at the removal opening 22 of which a cap unit 50 is provided.
- This cap unit 50 in turn consists of a base element 52 to which a pivotable cap element 56 is attached via a joint 54 .
- the base element 52 and the cap element 56 are always part of a one-piece component which also forms the joint 54 designed as a film hinge.
- the base element 52 which is fixed to the liquid reservoir 20 by means of a clamping device 52C of an inner shell 52B, has a central opening through which a pumping device 30 protrudes, with in particular only an actuating button 32 of the pumping device 30 protrudes from the opening in the base element 52 with a discharge opening 34 provided thereon.
- the pumping device 30 has a housing with a collar 31 which rests on a seal on an edge of the removal opening 22 .
- the pumping device also has a pumping chamber 36, the volume of which can be reduced by depressing the actuating pusher 32 against the force of a spring.
- An inlet channel 37 with an inlet valve 37A connects the pumping chamber with the liquid reservoir 20.
- An outlet channel 38 with an outlet valve 38A connects the pumping chamber with the discharge opening 34.
- the intended use of the dispenser provides that it is first opened for the purpose of use in that the previously closed cap element 56 is pivoted open in the manner described below, so that the actuating pusher 32 is then depressed in a dispenser main direction 2 and thereby liquid flows through the discharge opening in a discharge direction 4 can be discharged.
- the liquid is atomized into fine droplets as intended.
- the dispenser has an approximately rectangular, flattened cross-sectional shape on the liquid reservoir 20, on the base element 52 or its outer shell 52A and on the cap element 56, whose short sides are approximately parallel to the discharge direction 4 and whose long sides run approximately parallel to the transverse direction 6.
- the discharge direction 4 illustrated in the illustrations represents the preferred orientation, but the actuating pusher 32 with discharge opening 34 can also be rotated depending on the design, in particular to allow rotation through 180° for left-handed use.
- the hinge 54 and a retainer 60 for securely closing the cap unit 50 are provided on the opposite short sides of this rectangular shape.
- the actuating button 32 and the discharge opening 34 are oriented in such a way that the discharge takes place towards one of the long sides and is triggered by depressing over the opposite long side of said rectangular shape.
- the closing edge 53 which closes the base element 52 at the top edge and against which the cap element 56 rests in the closed state, has a comparatively complex shape.
- This terminating edge is highest on the short sides in the joint area 53A and in the opposite holding area 53C.
- the terminating edge is partially lowered, so that with a short design of the dispenser, it is easy to operate and the safe dispensing of liquid is ensured.
- an engagement extension 62F of a holding contour 62A on the base element engages in an opening 66F in a holding contour 66A of the cap element 56.
- the engagement extension 62F is provided at the upper end of a release surface 62B, which is favored by the relatively easily pressed can be.
- the release surface 62B can be easily detected haptically by profiling 62D.
- Figs. 4 to 6 The embodiment of Figs. 4 to 6 is characterized by an approximately circular-cylindrical shape of the cap unit 50 and by a likewise circular-cylindrical shape of the liquid reservoir 20.
- the dispenser 10 of Figs. 4 to 6 is identical to that of Figs 1 to 3 largely comparable.
- the terminating edge 53 on the base element 52 is designed with different heights.
- the retaining contours 62A, 66A are also formed similarly to the previous embodiment.
- the base element 52 is fastened directly to a neck of the liquid reservoir 20 instead of to a crimp sleeve 28, as is provided in the design of FIGS.
- the pumping device 30 is secured to the liquid reservoir 20 by means of the base element 52 and without an additional crimp sleeve 28 .
- a holding surface 52E presses from above against the collar 31 of the pump housing and this against the edge of the removal opening 22.
- the basic functionality is again similar to that of FIGS. 1 to 3.
- the dispenser is flattened, but its cross section has a substantially oval shape.
- the release surface 62B is designed so that it can be pressed in comparatively easily by means of free cuts 62C.
- a lifting surface 66G is provided on the outside of the cap element 56, which is protectively covered by a protective section 62G attached to the end of the base element 52 in the manner of a bridge .
- This protective portion 62G has the non-depressed Condition has dimensions by which the lifting surface 66G is covered and thus not inadvertently lifted by a force from below. This can be seen in particular in FIG.
- FIGS. 13A to 13C In order to raise the cap member 56, the procedure is as illustrated in FIGS. 13A to 13C.
- the protection section 62G is pressed in radially by means of a finger, in particular the thumb, for example by about 2 mm. Due to the bridge-like design, this is possible by means of a structurally well-definable force. It is preferably possible to press in by 1.5 mm with a force of 10 Newtons.
- the lifting surface 66G or a part thereof is exposed as it were.
- the thumb upwards the lifting surface can then be subjected to a force and the cap element 56 can thus be pivoted open.
- the arrows in Figure 13B illustrate the movement.
- the arrow in FIG. 13C illustrates the subsequent swinging open, which can preferably occur abruptly by prestressing the joint 54 .
- FIGS. 4 to 6 illustrate a special shape of the lateral surfaces of the base element 52 and the cap element 56 that abut one another in the closed state.
- the configuration of the lateral surfaces on a dispenser 10 according to FIGS. 4 to 6 is shown as an example. However, it could also be used with a different type of dispenser according to the invention.
- the lateral surfaces do not have any planar terminating edges 52D, 56D, but are formed with an engagement structure 56E, 52E on the terminating edges 52D, 56D.
- a partial or largely circumferential central elevation is provided on the closing edge 52D of the base element 52 and a partial or largely circumferential groove 56E is provided on the closing edge 56D of the cap element 56 .
- these structures 52E, 56E engage in one another when the dispenser 10 is in the closed state and lead to a form fit in relation to a radial direction. The dispenser 10 is thereby closed more securely.
- the structures 52E, 56E are also advantageous with regard to the automated assembly of the dispensers.
- the risk is reduced that in an automated assembly step, in which the dispenser is closed by pivoting the cap element, the walls of the cap element and the base element slide past one another.
