Description

TECHNICAL FIELD

[0001] The present invention relates to a pump dispenser and to a cap unit thereof. In particular, but not exclusively, to a dispenser configured for dispensing a liquid containing nicotine as a smoking substitute. BACKGROUND

[0002] In dispensers of this type simple and almost subconscious usability is important. At the same time, however, such dispensers should be protected against access by children and / or unintentional opening or even manipulation, which does not allow the usability to be significantly worsened. Furthermore, manufacturing costs are very critical in such dispensers, since the dispensers according to the invention are preferably not refillable. SUMMARY

[0003] It is the task of the present invention to provide a pump dispenser which allows a closed safety possibility and simple opening at low manufacturing costs.

[0004] According to the invention, for this purpose, firstly a pump dispenser for dispensing a liquid in atomized form is proposed, which has a liquid reservoir for accommodating the liquid before the dispensing with a withdrawal opening and a pump device which is arranged at the withdrawal opening. The liquid reservoir can be formed by a one-piece body. However, the liquid reservoir can also have a housing and an inner accommodating container (such as a bag) separately. The volume of the liquid reservoir is preferably relatively small, since the dispenser is to be able to be carried in a trouser pocket in many preferred areas of application. Preferably, the liquid reservoir can accommodate up to 100 ml, in particular up to 50 ml. A liquid reservoir with a maximum accommodation of 20 ml or less is also significantly smaller can also be suitable.

[0005] The liquid can be conveyed from the liquid reservoir to the withdrawal opening via a manipulation depression which can be depressed in the main direction of the pump dispenser. The withdrawal opening is preferably integrated in the manipulation depression here and is preferably perpendicular to the main direction defined by the manipulation direction.

[0006] The pump device for the pump dispenser according to the invention generally comprises a pump chamber, the volume of which can be reduced by depressing the manipulation depression, and which is connected to the liquid reservoir via an inlet channel with an inlet valve. Preferably, the pump device according to the invention has a discharge channel to the withdrawal opening, in which a discharge valve is arranged, which is opened directly mechanically by the pressure upstream or by depressing the manipulation depression.

[0007] The pump dispenser has a cap unit with a base element fastened at the liquid reservoir and a cap element which can be pivoted relative to the base element on the basis of a hinge. Preferably, a one-piece component consisting of plastic is provided which forms the base element and the cap element or the main parts thereof in one piece, wherein the hinge between them is also configured in one piece for this and is preferably configured as a film hinge.

[0008] The base element encloses an inner region in which a part of the pump device is arranged. In particular, a manipulation squeeze of the pump device preferably projects through this region so that it can be manipulated in the open state of the cap unit.

[0009] In the closed state, the cap unit covers the manipulation squeeze and the discharge opening and thus forms protection against dirt from the outside and / or against residual liquid from the cap interior. In the open state, the cap element releases the manipulation squeeze and the discharge opening.

[0010] The pump dispenser according to the application is in particular provided for the application purpose in the context of which it is carried by people in everyday life, in particular as a pump dispenser for liquid containing nicotine or as a dispenser for hand sanitizer.

[0011] In order to ensure uncomplicated use of the dispenser and still a safe closed state, two constructional ways are provided which can also be realized in combination.

[0012] According to a first constructional way, the cap unit has opposite to the hinge a holding device for fixing the closed state of the cap element, which has a first holding contour on one side of the base element and a second holding contour on one side of the cap element. The holding contours, which should point towards each other in the closed state, engage into each other and in particular cause a form-fit connection. On one side of the base element, an outer release face is provided, which in particular protrudes preferably by color or in particular by a shape perceptible haptically, and by means of which the holding contour of the base element can be at least partially displaced and in particular can be pressed radially in, so that the form-fit connection can thereby be cancelled, so that the cap element can subsequently be pivoted open or automatically spring open depending on the design of the cap unit.

[0013] The holding contours are preferably designed in the manner of an inner-side recess or in the manner of a passage opening on one side of the cap unit and an outwardly pointing access protrusion on one side of the base unit. The access protrusion is deflected radially inwards by means of the release face. In the closed state of the cap element, the access protrusion is positioned in the recess or the passage opening. This results in a form-fit connection which cannot be opened non-destructively, preferably without prior deflection of the release face.

[0014] Especially if the holding device is to fulfill a childproof function, it is preferred to be set up in such a way that the cap element cannot be opened non-destructively or destructively with a pulling force of less than 30 Newton without deflecting the release face.

[0015] It should also be noted, especially in the case of a childproof design of the holding device, that the release face cannot be pressed in too easily. It is still advisable, however, to slightly decouple the release face from the adjacent outer face of the base element, for example by a free cut on both sides of the release face and / or by the base element having a smaller average thickness in the region of the release face than in the adjacent region of the outer face.

[0016] In order to also not have to press on the release face when closing, at least one of the holding contours is preferably provided with a lead-in ramp, so that the holding contour at the base element is thereby deflected inwards when the cap element is closed and finally snaps into its latching position.

[0017] A second design (which can be combined with the first design described) provides that the holding device has a lifting face on one side of the cap element which points downwards. In correspondence therewith, a protection section is provided on one side of the base element which covers the lifting face when the cap element is closed and thereby prevents a vertical and upwardly directed force loading which pivots the cap element open, so that unintentional opening becomes less likely. As with the release face mentioned, the protection section is also preferably highlighted in terms of color or shape, for example provided with a profile. The protection section is designed in such a way that it withstands a vertical force loading or at least protects the lifting face from a vertical force loading. At the same time, however, the protection section can be pressed in radially by means of a finger, in particular the thumb, so that the lifting face is thereby engaged from below by the finger and can then be pressed upwards by means of the finger.

[0018] In this second design it can be provided that no holding contour acting especially form-fittingly is provided in correspondence with the first design. Instead it can be provided that the cap element and the base element in the closed state are only coupled in a force-fitting manner. In the case of a still possible combination with the first design it is preferred to provide that the protection section simultaneously constitutes the release face for decoupling.

[0019] The lifting face should as far as possible not be a sharp edge in order to allow for an easy opening. Especially the lifting face is preferably designed flat or only slightly convexly or concavely curved. As already described, the lifting face can be made accessible by pressing in the protection section. The protection section here can preferably be displaced sufficiently freely so that the protection section releases at least one section of the lifting face of 1.5 mm width of the lifting face with a 10 Newton radially oriented manipulation force. With regard to the face, such a manipulation force preferably leads to an exposure of at least 10 mm2 , in particular preferably at least 20 mm 2 of the raised surface.

[0020] It has proven particularly advantageous for the protection section to be in the form of a bridge-like element which is moulded at adjacent sections of the base element on the end side and is freely cut on the lateral side. Such a bridge-like shape constitutes an effective protection against deformation in the direction of the raised surface and can be configured very well in order to achieve the desired resistance of the protection section against radial deformation.

[0021] The raised surface can be formed directly by a lower edge of the cap element. However, since such an edge is mostly too narrow to allow for easy opening, it is preferred if the raised surface is formed at least also by the underside of a horizontal raised tab which projects outwards from the cap region of the cap element. This raised tab can be provided annularly, but is preferably provided only on one side at the cap element.

[0022] The base element of the cap unit is indirectly or directly coupled with the liquid reservoir, for example via a snap connection, which preferably results in a higher resistance against separation, so that the child cannot separate the entire cap unit from the liquid reservoir.

[0023] One constructional possibility provides that the pump device is fastened at the liquid reservoir by means of a crimp sleeve, and the snap connection is used to fix the base element at the crimp sleeve.

[0024] A further aspect of the application relates to a pump dispenser, in particular of the type described, in which the mentioned crimp sleeve is dispensed with and instead it is provided that the base element is provided for direct fastening at the liquid reservoir and has a holding surface which is oriented in the direction of the extraction opening of the liquid reservoir, by means of which the pump device is fastened at the liquid reservoir, in particular 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.

[0025] The base element of the cap unit thus fulfils a further function here by fixing the pump device at the liquid reservoir. The dispenser according to the application can thus consist of a very small number of components in addition to the pump device. In the extreme case, it is only the liquid reservoir, the one-piece cap unit and, if necessary, a sealing ring between the pump device and the extraction opening of the liquid reservoir.

[0026] Preferably, the pump device has an external, annular collar which rests on the edge surrounding the extraction opening or a sealing ring there. The holding surface of the base element presses against this collar in the direction of the liquid reservoir.

[0027] The retaining face is preferably configured in the form of a ring face, opposite which a stop face is arranged which limits the movability of the handling extrusion.

[0028] As already explained, the base element is preferably used for fastening at the liquid reservoir and serves as a carrier for the described release face and / or the described protection section. In order to be able to fulfill both functions, the base element preferably has an inner shell at the inner side of which a clamping device is arranged for fastening the base element at the liquid reservoir, and an outer shell at which the release face or the protection section is arranged. The inner shell can be divided by axial cutting into tongue sections which are snap-locked in a prescribed circumferential distribution at the described crimp sleeve or directly at the outlet of the liquid reservoir.

[0029] When the cap unit is in the closed state, the lower termination edge of the cap element preferably lies very largely peripherally against the upper termination edge of the base element. In one particularly simple design, this upper termination edge can extend in a uniform plane which is oriented orthogonally to the main direction of the dispenser.

[0030] It is however preferred that the upper termination edge has a non-uniform extension with respect to the main direction in the direction of the cap element. In this way, the termination edge can extend further upwardly, especially in the hinged region of the termination edge, than in the handling region of the termination edge, which is engaged from above by the user for handling the handling extrusion. This handling region, which is preferably offset by 90° with respect to the hinged region, thus allows easy handling of the handling extrusion and a shorter design of the dispenser overall. The termination edge can also extend further upwardly in the hinged region of the termination edge than in the discharge region of the termination edge, in the direction of which the discharge opening is oriented or can be oriented in the case of a rotatable handling extrusion with a discharge opening. The thus reduced termination edge in the region of the discharge opening also contributes to a shorter design of the dispenser.

[0031] As described in the context of the hinged region, it is likewise advantageous if the termination edge extends further upwardly in the holding region opposite the hinged region than in the mentioned handling region and / or the mentioned discharge region of the termination edge.

[0032] Preferably, the base element and the cap element are provided in the region of the termination edge with a joint action, especially with at least one protrusion and a corresponding recess, by means of which the base element and the cap element are fixed to one another in the closed state in the radial direction in a form-fit. This especially makes it easy to automate the assembly of the dispenser and also later manual operation when using the dispenser.

[0033] The structure preferably extends over an angle of at least 90°, in particular preferably over an angle of at least 120°, at the base element and the cap element.

[0034] One possible structural version of the dispenser is provided in that the dispenser has a substantially rotationally symmetrical outer shape, wherein in this case the dispenser preferably has a cylindrical shape over the main length, which is rounded or tapered at the ends if necessary.

[0035] However, for regular operation of the dispenser, in particular for an operation that should be able to take place almost subconsciously and frequently, it has proven advantageous if the base element or the entire cap unit or the entire dispenser has an outer contour with respect to the projection in the main direction that is different from a circular shape. Such a base element or such a cap unit is thus flattened over its entire length, wherein the outer contour preferably has a substantially rectangular or oval shape in cross section. Preferably, the liquid reservoir is flattened to the same extent.

[0036] Such a flattened structural version can be used particularly simply without visual checking of the orientation. In particular, the outer contour of the base element can have a smaller extension in the direction of the discharge direction defined by the discharge opening than in a direction at right angles to this direction and to the main direction. In such a case, the hinge is preferably arranged at the short side of the base element. This allows particularly ergonomic operation, in which the liquid reservoir is held with the hand, the cap element is released with the thumb, and the actuating squeeze is then pressed down with the index finger. In order to be able to operate with the left hand and with the right hand as well, the dispenser is preferably correspondingly symmetrically configured.

[0037] Operation without visual checking of the orientation by the user can also be improved in particular by the already described haptically perceptibility of the release face and / or of the protection section, for example with a profile, such as a raised rib on the release face or on the protection section.

[0038] The pump dispenser according to the application can be used as a pharmaceutical dispenser. For example, the liquid reservoir can be filled with a painkiller such as lidocaine for oral administration.

[0039] In particular, the application field of dispensing nicotine-containing liquids for oral administration is considered an important application field. The pump dispenser according to the application is particularly well suited to this application field with its advantageous manufacturability and its greater safety, also in terms of child protection, and also with its simple operability, as far as the acceptance by the user in the case of use as a smoking substitute is concerned.

[0040] Another important application field is the field of disinfectant dispensers, in particular the field of disinfectant dispensers for hand disinfectants and other dispensers that are provided for topical application of liquids on the skin of a user.

[0041] The application of a liquid atomized thereon, not taken up or applied on the skin, but for example on the surface of an object, can also be achieved with the pump dispenser according to the application and is included by the application. BRIEF DESCRIPTION OF DRAWINGS

[0049] Figures 1-13C In total, four embodiments of the pump dispenser 10 according to the application are shown, which consistently have the following features.

[0050] Respectively, a pump dispenser 10 is concerned, which is intended to be carried by people in everyday life, for example in order to carry a disinfectant or a smoking substitute product containing nicotine. The dispenser respectively has a liquid reservoir 20 with an internal volume of for example 20 ml, at the extraction opening 22 of which a cap unit 50 is arranged. This cap unit 50 in turn consists of a base element 52 at which a pivotable cap element 56 is attached via a hinge 54. In the embodiments presented, the base element 52 and the cap element 56 are always part of a one-piece component which additionally also forms the hinge 54 configured as a film hinge.

[0051] Furthermore, in all four embodiments it is provided that the base element 52, which is fixedly arranged in relation to the liquid reservoir 20 by means of the clamping device 52C of the inner housing 52B, has a central passage through which the pump device 30 protrudes, wherein, in particular, only the actuating squeeze 32 of the pump device 30 with the discharge opening 34 arranged thereat protrudes from the passage in the base element 52.

[0052] As can be seen for all embodiments, the pump device 30 has a housing with a collar 31 which rests on a seal on the edge of the extraction opening 22. The pump device furthermore has a pump chamber 36, the volume of which can be reduced by pressing down the actuating squeeze 32 against the force of a spring. An inlet channel 37 with an inlet valve 37A connects the pump chamber with the liquid reservoir 20. An outlet channel with an outlet valve 38A connects the pump chamber with the discharge opening 34. Figure 3

[0053] The prescribed use of the dispenser is provided in that, for the purpose of use, the dispenser is first opened by pivoting the previously closed cap element 56 in a manner to be described below, so that subsequently the actuating squeeze 32 can be pressed down in the dispensing main direction 2 and thereby causes the liquid to be discharged through the discharge opening in the discharge direction 4. The liquid is atomized into fine droplets in the prescribed manner here.

[0054] In the design according to Figures 1-3 the dispenser has an approximately rectangular flat cross-sectional shape at the liquid reservoir 20, at the base element 52 or its housing 52A and at the cap element 56, the short sides of which extend approximately parallel to the discharge direction 4 and the long sides of which extend approximately parallel to the transverse direction 6. It should be noted, however, that the discharge direction 4 illustrated in the drawing is the preferred orientation, but the actuating squeeze 32 with the discharge opening 34 can also be rotatable in design, in particular in order to allow a 180° rotation for use by left-handed persons.

[0055] The hinge 54 and the retaining device 60 for the secure closure of the cap unit 50 are provided on the opposite short sides of the rectangular shape. The actuating squeeze 32 and the discharge opening 34 are oriented in such a way that the discharge takes place in the direction of one of the long sides and is triggered by pressing down on the opposite long side of the mentioned rectangular shape.

[0056] ​The termination edge 53, which terminates the base element 52 above at the edge side and against which the cap element 56 lies in the closed state, has a relatively complex shape. It is configured highest at the short sides in the hinged region 53A and the oppositely situated holding region 53C. Conversely, it is partially lowered at the long sides of the rectangular shape in the handling region 53B and the discharge region 53D, thus enabling comfortable handling and ensuring safe discharge of the liquid in the case of a short construction shape of the dispenser.

[0057] In the closed state shown in Figure 1 , the access protrusion 62F of the holding profile 62A on the base element side engages into the passage 66F of the holding profile 66A of the cap element 56. The access protrusion 62F is provided at the upper end of the release face 62B, which can advantageously be pressed in relatively easily as a result of the access protrusion. The release face 62B is well perceptible haptically by means of the profile 62D. The access protrusion 62F is pulled out of the passage 66F by deflecting it by means of the release face 62B, so that the cap element 56 is engaged from below, in particular by the thumb, which pressed in the release face 62B, and is pushed upward to pivot open. The open state is thus achieved. The lead-in ramps 62E, 66E facilitate the establishment of the latched closed state without difficulty when the cap element 56 is closed.

[0058] Figures 4-6 The design variant according to Figures 4-6 is characterized by the substantially cylindrical shaping of the cap unit 50 and the likewise cylindrical shaping of the liquid reservoir 20. However, in terms of functionality, Figures 1-3 The dispenser 10 according to is largely similar to the dispenser according to

[0059] . In a similar manner to the foregoing, the termination edge 53 at the base element 52 is designed with different heights. The holding profiles 62A, 66A are also configured similarly to the preceding embodiment. Figures 1-3 However, in contrast to the preceding embodiment, the fastening of the base element 52 is carried out directly at the neck of the liquid reservoir 20, not, as in the design according to

[0060] , at the crimp sleeve 28. The pump device 30 is fixed here at the liquid reservoir 20 by means of the base element 52 and without an additional crimp sleeve 28. For this purpose, the holding face 52E presses against the collar 31 of the pump housing from above and presses the collar against the edge of the extraction opening 22. Figures 7-9 Figures 1-3Similar. Here too, a flat design of the dispenser occurs, but the cross section of the dispenser has a substantially oval design. Furthermore, it is provided here as a feature that the release face 62B is relatively easily designed pressingly due to the free-cutting portion 62C.

[0061] In the dispenser according to Figures 10-12 , a slightly different technology is provided, because here no form-fittingly interengaging holding contours 62A, 66A are provided. Instead, in the closed state, the cap element 56 is simply clamped to the base element 52, so that the cap element can be opened by a force oriented in the pivoting-open direction alone.

[0062] In order to ensure in such a design that the cap element 56 is not opened accidentally, but can still be easily opened, a lifting face 66G is provided on the outside at the cap element 56, which is protectively covered at the base element 52 by a bridge-like end-side fastening protective section 62G. This protective section 62G has in the unpressing state a dimension by which the lifting face 66G is covered and thus not accidentally lifted from below by a force. This can be seen in particular in Figure 10 .

[0063] In order to lift the cap element 56, this is done as elucidated in Figures 13A-13C . The protective 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 can be achieved by means of a structurally well-defined force. Preferably, a pressure of 1.5 mm can be achieved with a force of 10 Newton. By the pressing in, the lifting face 66G or a portion thereof is as it were exposed. By pressing the thumb upwards, the lifting face can then be force-loaded and thus the cap element 56 pivoted open. The movement is illustrated by the arrow in Figure 13B . The subsequent pivoting open, which can preferably take place suddenly due to the pre-tensioning of the hinge 54, is illustrated by the arrow in Figure 13C .

[0064] Figure 14 and Figure 14A illustrate the special shaping of the side surfaces of the base element 52 and the cap element 56, which in the closed state abut against each other. Exemplarily, the shaping of the side surfaces at the dispenser 10 corresponds to Figures 4-6 . However, this shaping can also be used in different types of dispensers according to the application.

[0065] In Figure 14AIn the manner shown in the figures, the side surfaces do not have a flat termination edge 52D, 56D, but are configured with a joining structure 56E, 52E at the termination edge 52D, 56D. At present, a partly or largely encircling central elevation is provided at the termination edge 52D of the base element 52, and a partly or largely encircling groove 56E is provided at the termination edge 56D of the cap element 56.

[0066] As is set forth in Figure 14B these structures 52E, 56E mutually engage in the closed state of the dispenser 10 and lead to a form fit with respect to the radial direction. Thereby, the dispenser 10 is more securely closed.

[0067] However, the structures 52E, 56E are furthermore advantageous in terms of automated assembly of the dispenser. The danger is reduced that the wall of the cap element and the wall of the base element slide past one another in the automated assembly step, in which the dispenser is closed by pivoting the cap element.
