Definitions
- the invention relates to dispensing device as well as to a method for the manufacture thereof.
- the term “dispensing device” is to be particularly understood as a dosing pump or hand-operated pump for the dispensing of a preferably cosmetic liquid. However, it can also be any other dispensing device such as a container, output or spray head, dispenser or the like, particularly for a cosmetic liquid.
- cosmetic liquid is to be understood, in a narrower sense, as cosmetics, hair spray, hair lacquer, a deodorant, a foam, a gel, a color spray, a sun protection or skin care agent or the like.
- body care products, cleaning products or the like, and even suspensions and fluids, particularly those with gas phases are included as well.
- other liquids for example air improvers and particularly technical liquids and fluids as well such as rust removers and the like, can as be used. Nonetheless, for the sake of simplicity and due to the emphasized use, there is often just mention of cosmetic liquid in the following.
- Dispensing devices with a lower part and an elastic upper part are known.
- the upper part is preferably welded to the upper part in order to create a liquid-tight pump chamber.
- a liquid can be forced and dispensed from the pump chamber.
- an automatic elastic restoration of the upper part or actuating section into its previous place occurs, with new liquid being sucked into the pump chamber.
- One aspect of the present invention consists in connecting two components with each other in a liquid-tight manner.
- the first component has a recess and the second component a projection or vice versa.
- a first at least substantially complementary section engages in the recess and is connected with same by means of temporary liquefied and/or deformed material which is formed by a second section of the projection and/or is injected into the recess.
- the liquefaction of the material occurs particularly by means of ultrasound or in another suitable manner.
- the second section of the projection preferably connected to the free end of the first section can be liquefied during assembly and connect the first section with the wall of the recess and/or fill out gaps present therebetween, so that the desired liquid-tight connection is created.
- the second section particularly constitutes an additional material supply of the projection which is liquefied during assembly—particularly through ultrasound welding—in order to finally connect the two components with each other.
- the ultrasound can be introduced via the flat side of the component bearing the projection facing away from the projection—particularly via a raised area opposite the projection.
- the material for the connecting of the projection with the recess and for the filling-out of gaps is not formed (solely) by the second (additional) section of the projection, but rather is alternatively or additionally injected through a channel in liquid form into the recess and, particularly, through the projection—particularly up to its free end.
- the recess is embodied as a through hole.
- the projection reaches through the through hole, with the second section of the projection extending beyond the through hole and being particularly thermally deformed such that it engages behind and positively holds the first component.
- the recess or through hole is embodied as a through borehole and/or the projection is embodied in the manner of a bolt or cylindrically (prior to the deformation thereof).
- FIG. 1 shows a schematic view of a proposed dispensing device according to a first embodiment
- FIG. 2 shows an enlarged section of FIG. 1 of two components which have not yet been connected with each other;
- FIG. 3 shows an enlarged section of FIG. 1 with two connected components
- FIG. 4 shows a sectional schematic view of a proposed dispensing device according to a second embodiment
- FIG. 5 shows a sectional schematic view of a proposed dispensing device according to a third embodiment
- FIG. 6 shows a sectional schematic view of a proposed dispensing device according to a fourth embodiment with two components which have not yet been connected with each other.
- FIG. 1 shows a first embodiment of a proposed dispensing device 1 for the dispensing of a preferably cosmetic liquid 2 in the sense named at the outset.
- the liquid 2 can be considerably more viscous than water or, optionally, even pasty.
- Allocated to the dispensing device 1 is preferably a bag or container 3 for supplying liquid 2 to which the dispensing device 1 is detachably connected as needed or vice versa. For instance, a changing of the bag 3 or the like and/or a refilling of the liquid 2 can optionally occur.
- the dispensing device 1 can also form a reservoir for the liquid 2 or the container itself.
- the dispensing device 1 preferably has a first component 4 , particularly a lower part, and a second component 5 .
- the second component 5 is connected or can be connected with the first component 4 , preferably in a non-detachable, liquid-tight and, particularly, gas-tight manner.
- the first and/or second component 4 , 5 is preferably rigid and/or a single part, particularly injection molded from a suitable, preferably food-safe plastic, particularly a polyolefin such as PP (polypropylene) or PE (polyethylene), or manufactured in another manner.
- a suitable, preferably food-safe plastic particularly a polyolefin such as PP (polypropylene) or PE (polyethylene), or manufactured in another manner.
- the second component 5 preferably serves to affix or hold another component, particularly an upper part or elastically deformable part or section 6 .
- the section 6 is formed from the second component 5 or formed onto same or vice versa.
- the second component 5 is preferably injected onto the section 6 or otherwise connected therewith in a non-detachable and liquid-tight manner.
- This makes simple manufacture possible, for example by means of so-called “bi-injection,” i.e. particularly the injection of another material in the same injection mold in which the first material is formed. Particularly, a chemical and/or mechanical connection is thus made possible.
- the second component 5 can also be connected or held with the section 6 by means of an undercut, recess, through hole, overlap, or the like.
- the other component and the second component 5 can also be separate components.
- the terms “lower part” and “upper part” correspond to the preferred arrangement or orientation of the dispensing device 1 during normal use. This is not necessarily the case, however. Accordingly, depending on the requirement, application, design and the like, the lower part and the upper part can also be located or oriented in any spatial alignment with respect to each other.
- the section 6 is preferably designed to be elastically deformable. Especially preferably, an accommodating or pump chamber P for the liquid 2 is formed between the first component 4 and the other component or section 6 or delimited therefrom, at least in part.
- the dispensing device 1 is preferably embodied as a pump with an inlet valve 7 and a discharge valve 8 .
- the section 6 forms the inlet valve 7 and/or outlet valve 8 together with the first component 4 .
- the valves 7 , 8 can also be formed separately.
- the valves 7 , 8 are preferably embodied as self-closing one-way valves.
- the volume of the pump chamber P can be made smaller through the deformation of the section 6 starting from the resting and initial position shown in FIG. 1 , thus forcing liquid 2 from the pump chamber P and dispensing same.
- an optional actuating element 9 is preferably pressed down manually in the direction of the arrow N for this purpose, thus pressing down at least an actuating section 10 of the section 6 .
- the actuating element 9 is allocated to a preferably cap-like housing part 11 or formed therefrom.
- the housing part 11 forms a lever which can preferably be slid axially, tipped or pressed in to actuate the covering device 1 or the pump formed therefrom.
- the liquid 2 Upon pressing down or pumping, the liquid 2 is delivered or dispensed via the discharge valve 8 .
- the opening of the discharge valve 8 occurs automatically, preferably due to the pressure of the liquid and/or—or, optionally, in addition—due to a corresponding deformation of the section 6 while being pressed down.
- the discharge valve 8 is preferably arranged laterally next to the actuating section 10 or a preferably dome- or hemispherical area of the section 6 .
- the discharge valve 8 is preferably formed by a valve element, for example one in the manner of a flap, which is particularly formed on the second component 5 or the section 6 or is formed therefrom.
- the discharge valve 8 is connected to the pump chamber P via a connection channel 12 . Particularly, the opening of the discharge valve 8 occurs automatically as a result of the pressure of the liquid. The liquid 2 can then flow out and be dispensed via a connecting discharge channel 13 and/or a nozzle 14 or the like.
- liquid 2 is discharged or sprayed or atomized from the nozzle 14 upon pressing down of the actuating element 9 or housing part 11 .
- the dispensing of liquid 2 through the dispensing device 1 can also occur in a non-atomized state.
- the inlet valve 7 preferably has a valve flap 15 formed on the section 6 or the second component 5 which is pretensioned against an inlet opening 16 and is particularly arranged in the pump chamber P.
- the valve flap 15 which is embodied, for example, in the manner of a leaf spring, is pretensioned against the inlet opening 16 by means of a pretensioning element 17 which is likewise preferably flap- or bridge-like.
- the pretensioning element 17 is particularly formed on the section 6 or actuating section 10 .
- the pretensioning element 17 supports the closing of the valve flap 15 —particularly in the case of higher-viscosity liquid 2 as well—and ensures that the inlet valve 7 also remains closed during normal operation.
- liquid 2 can be taken up or sucked via a preferably provided connection 18 connected to the inlet valve 7 or the inlet opening 16 and particularly a suction line 19 connected thereto and extending into the container 3 .
- the inlet valve 7 or the valve flap 15 is then opened, as indicated with a broken line in FIG. 1 .

Abstract
The invention relates to a dispensing device for a preferably cosmetic liquid, and to a method for producing one such dispensing device. Two components are interconnected in a liquid-tight manner. The first component comprises a recess and the second component comprises a projection. The projection engages in the recess by means of a section which is complementary to the recess. The connection is created by means of a temporarily liquefied and/or deformed material which is formed by a second section connected to the first section of the projection and/or is injected into the recess, especially via a channel through the projection.
Description
- The invention relates to dispensing device as well as to a method for the manufacture thereof.
- In the present invention, the term “dispensing device” is to be particularly understood as a dosing pump or hand-operated pump for the dispensing of a preferably cosmetic liquid. However, it can also be any other dispensing device such as a container, output or spray head, dispenser or the like, particularly for a cosmetic liquid.
- The term “cosmetic liquid” is to be understood, in a narrower sense, as cosmetics, hair spray, hair lacquer, a deodorant, a foam, a gel, a color spray, a sun protection or skin care agent or the like. Preferably, however, in a broader sense, other body care products, cleaning products or the like, and even suspensions and fluids, particularly those with gas phases, are included as well. Moreover, other liquids, for example air improvers and particularly technical liquids and fluids as well such as rust removers and the like, can as be used. Nonetheless, for the sake of simplicity and due to the emphasized use, there is often just mention of cosmetic liquid in the following.
- Dispensing devices with a lower part and an elastic upper part are known. The upper part is preferably welded to the upper part in order to create a liquid-tight pump chamber. By pressing down on the upper part or at least on an actuating section of the upper part, a liquid can be forced and dispensed from the pump chamber. Subsequently, an automatic elastic restoration of the upper part or actuating section into its previous place occurs, with new liquid being sucked into the pump chamber.
- It is the object of the present invention to propose an improved dispensing device and a method for the manufacture thereof, so that a liquid-tight connection can be created between two components in a simple and/or secure manner.
- The above object is achieved by a dispensing device as set forth in
claim 1 or by a method as set forth inclaim 18. Modifications are the object of the subclaims. - One aspect of the present invention consists in connecting two components with each other in a liquid-tight manner. The first component has a recess and the second component a projection or vice versa. In the liquid-tight, connected state, a first at least substantially complementary section engages in the recess and is connected with same by means of temporary liquefied and/or deformed material which is formed by a second section of the projection and/or is injected into the recess. This permits the simple manufacture of a high-grade liquid-tight connection, hence making a very secure seal which is particularly suitable for mass production.
- The liquefaction of the material occurs particularly by means of ultrasound or in another suitable manner. For instance, according to one embodiment, the second section of the projection preferably connected to the free end of the first section can be liquefied during assembly and connect the first section with the wall of the recess and/or fill out gaps present therebetween, so that the desired liquid-tight connection is created. In this case, the second section particularly constitutes an additional material supply of the projection which is liquefied during assembly—particularly through ultrasound welding—in order to finally connect the two components with each other. Especially preferably and effectively, the ultrasound can be introduced via the flat side of the component bearing the projection facing away from the projection—particularly via a raised area opposite the projection.
- According to another embodiment, the material for the connecting of the projection with the recess and for the filling-out of gaps is not formed (solely) by the second (additional) section of the projection, but rather is alternatively or additionally injected through a channel in liquid form into the recess and, particularly, through the projection—particularly up to its free end.
- According to another embodiment, the recess is embodied as a through hole. In this case, the projection reaches through the through hole, with the second section of the projection extending beyond the through hole and being particularly thermally deformed such that it engages behind and positively holds the first component. Preferably, the recess or through hole is embodied as a through borehole and/or the projection is embodied in the manner of a bolt or cylindrically (prior to the deformation thereof).
- Further advantages, features, characteristics and aspects of the present invention follow from the claims and the following description of preferred embodiments on the basis of the drawing.

FIG. 1 shows a first embodiment of a proposeddispensing device 1 for the dispensing of a preferablycosmetic liquid 2 in the sense named at the outset. Theliquid 2 can be considerably more viscous than water or, optionally, even pasty. - Allocated to the
dispensing device 1 is preferably a bag orcontainer 3 for supplyingliquid 2 to which thedispensing device 1 is detachably connected as needed or vice versa. For instance, a changing of thebag 3 or the like and/or a refilling of theliquid 2 can optionally occur. Alternatively, thedispensing device 1 can also form a reservoir for theliquid 2 or the container itself. - The
dispensing device 1 preferably has afirst component 4, particularly a lower part, and asecond component 5. Thesecond component 5 is connected or can be connected with thefirst component 4, preferably in a non-detachable, liquid-tight and, particularly, gas-tight manner. - The first and/or
second component - The
second component 5 preferably serves to affix or hold another component, particularly an upper part or elastically deformable part orsection 6. Especially preferably, thesection 6 is formed from thesecond component 5 or formed onto same or vice versa. - In the depicted example, the
second component 5 is preferably injected onto thesection 6 or otherwise connected therewith in a non-detachable and liquid-tight manner. This makes simple manufacture possible, for example by means of so-called “bi-injection,” i.e. particularly the injection of another material in the same injection mold in which the first material is formed. Particularly, a chemical and/or mechanical connection is thus made possible. - Alternatively or in addition, the
second component 5 can also be connected or held with thesection 6 by means of an undercut, recess, through hole, overlap, or the like. However, the other component and thesecond component 5 can also be separate components. - In the illustration according to
FIG. 1 , the terms “lower part” and “upper part” correspond to the preferred arrangement or orientation of thedispensing device 1 during normal use. This is not necessarily the case, however. Accordingly, depending on the requirement, application, design and the like, the lower part and the upper part can also be located or oriented in any spatial alignment with respect to each other. - The
section 6 is preferably designed to be elastically deformable. Especially preferably, an accommodating or pump chamber P for theliquid 2 is formed between thefirst component 4 and the other component orsection 6 or delimited therefrom, at least in part. - The
dispensing device 1 is preferably embodied as a pump with aninlet valve 7 and adischarge valve 8. - Preferably, the
section 6 forms theinlet valve 7 and/oroutlet valve 8 together with thefirst component 4. However, thevalves valves - When the pump chamber P is filled with
liquid 2, the volume of the pump chamber P can be made smaller through the deformation of thesection 6 starting from the resting and initial position shown inFIG. 1 , thus forcingliquid 2 from the pump chamber P and dispensing same. In particular, an optional actuatingelement 9 is preferably pressed down manually in the direction of the arrow N for this purpose, thus pressing down at least an actuatingsection 10 of thesection 6. - Preferably, the actuating
element 9 is allocated to a preferably cap-like housing part 11 or formed therefrom. In the depicted example, thehousing part 11 forms a lever which can preferably be slid axially, tipped or pressed in to actuate the coveringdevice 1 or the pump formed therefrom. - However, it is also possible, for example, for a user (not shown) or other object to press directly on the
section 6 or actuatingsection 10 to dispense liquid. - Upon pressing down or pumping, the
liquid 2 is delivered or dispensed via thedischarge valve 8. In particular, the opening of thedischarge valve 8 occurs automatically, preferably due to the pressure of the liquid and/or—or, optionally, in addition—due to a corresponding deformation of thesection 6 while being pressed down. - In the depicted example, the
discharge valve 8 is preferably arranged laterally next to theactuating section 10 or a preferably dome- or hemispherical area of thesection 6. - The
discharge valve 8 is preferably formed by a valve element, for example one in the manner of a flap, which is particularly formed on thesecond component 5 or thesection 6 or is formed therefrom. - The
discharge valve 8 is connected to the pump chamber P via aconnection channel 12. Particularly, the opening of thedischarge valve 8 occurs automatically as a result of the pressure of the liquid. Theliquid 2 can then flow out and be dispensed via a connectingdischarge channel 13 and/or anozzle 14 or the like. - In particular, the
liquid 2 is discharged or sprayed or atomized from thenozzle 14 upon pressing down of theactuating element 9 orhousing part 11. Alternatively or optionally, the dispensing ofliquid 2 through thedispensing device 1 can also occur in a non-atomized state. - When there is a corresponding drop in the liquid pressure in the pump chamber P—particularly after the pressing down of the
actuating section 10 has ended—thedischarge valve 8 closes again, preferably automatically, particularly due to corresponding return forces. - After release, as a result of the inherent elasticity or return force of the
actuating section 10 or of thesection 6, a preferably automatic return to the initial position shown inFIG. 1 occurs, with new liquid being taken up, preferably sucked in, via theinlet valve 7 into the pump chamber P. The opening of theinlet valve 7 during the return occurs preferably as a result of the negative pressure present then in the pump chamber P. - The
inlet valve 7 preferably has avalve flap 15 formed on thesection 6 or thesecond component 5 which is pretensioned against aninlet opening 16 and is particularly arranged in the pump chamber P. Especially preferably, thevalve flap 15, which is embodied, for example, in the manner of a leaf spring, is pretensioned against the inlet opening 16 by means of apretensioning element 17 which is likewise preferably flap- or bridge-like. Thepretensioning element 17 is particularly formed on thesection 6 oractuating section 10. Thepretensioning element 17 supports the closing of thevalve flap 15—particularly in the case of higher-viscosity liquid 2 as well—and ensures that theinlet valve 7 also remains closed during normal operation. - During the return of the
section 6 oractuating section 10 from the pressed-down position (not shown) to the initial position shown inFIG. 1 ,liquid 2 can be taken up or sucked via a preferably providedconnection 18 connected to theinlet valve 7 or theinlet opening 16 and particularly asuction line 19 connected thereto and extending into thecontainer 3. Theinlet valve 7 or thevalve flap 15 is then opened, as indicated with a broken line inFIG. 1 . After the sucking or sucking in ofliquid 2 into the pump chamber P, theinlet valve 7 or itsvalve flap 15 preferably closes again automatically. - In the first embodiment, the
first component 4 has a preferably groove-like recess 10 and thesecond component 5 has a preferably bridge-like projection 21, particularly one which corresponds substantially to the recess. Theprojection 21 engages in therecess 10, with the twocomponents components - In the depicted example, the
component 5 or theprojection 21 is particularly annularly embodied and particularly peripherally arranged in a circumferential manner at least in sections, preferably around thesection 6 or actuatingelement 10. -
FIGS. 2 and 3 illustrate in enlarged sections ofFIG. 1 the preferred connection of the twocomponents FIG. 2 shows the twocomponents projection 21 already inserted into therecess 20.FIG. 3 shows the twocomponents - The
project 21 has afirst section 22 which is at least substantially complementary to therecess 20 and at least substantially rectangular in the depicted example in the axial section shown. Therecess 20 is preferably likewise at least substantially rectangular or slightly tapered in the axial section or cross section. In particular, thefirst section 22 is adapted in its radial width or thickness such that it can be inserted axially into therecess 20, particularly with slight radial play at most, which is to say with only small lateral gaps. The axial extension of thefirst section 22 corresponds at least substantially to the depth of the recess 20 (groove depth). - The
projection 21 further comprises asecond section 23 which connects to thefirst section 22 particularly at the free end or at the bottom 24 of therecess 20. Especially preferably, thesecond section 23 is tapered toward the groove bottom 24, particularly at least substantially trapezoid-shaped or triangular in its cross section as indicated inFIG. 2 . In the first embodiment, thesecond section 23 serves only to make (additional) material available for the connection of the twocomponents second section 23 is no longer present in the connected state of thecomponents components - The
recess 20 is preferably formed in aflat section 25 of thefirst component 4. Especially preferably, thefirst component 4 is worked off perpendicularly to theflat section 25 to form therecess 20. Theprojection 21 preferably protrudes away from aflat section 26 of thesecond component 5 or upper part, particularly at least substantially perpendicularly. In the assembled or connected state, the twoflat sections - On the side facing away from the
projection 21—particularly directly opposite theprojection 21—thesecond component 5 preferably has a raisedarea 27 for the targeted introduction of ultrasound, particularly by means of atransmission element 28 which can be mounted as indicated inFIG. 2 . The raisedarea 27 is particularly annular and, in cross section, at least substantially rectangular in order to be able to set the particularlyannular transmission element 28 of an ultrasound head or the like in place to weld the twocomponents - The radial width of the raised
area 27 preferably corresponds at most to five times the radial thickness of theprojection 21 in order to achieve a targeted introduction of the ultrasound and focusing in the area of theprojection 21. Especially preferably, the radial width of the raisedarea 31 is at least substantially two to three times the radial thickness of theprojection 21, particularly at least substantially two times or less. - During the introduction of ultrasound, the ultrasound is transmitted through the
second component 5, which is preferably at least substantially embodied in a single piece in the area of the axial ultrasound transmission, to the free end of theprojection 21, particularly to thesecond section 23. The ultrasound waves are focused through the tapered, particularly at least substantially pointedly or bluntly tapering end of thesecond section 23 and produce such a thermal influence in this area that the material of thesecond section 23 is liquefied, particularly with optimal additional pressure influence. This temporarily liquefied material then connects theprojection 21 or thefirst section 22 with the wall of therecess 20 and/or fills gaps between theprojection 21 and the wall of therecess 21, particularly toward the side walls of therecess 20, whereby a durable and liquid-tight and particularly also gas-tight connection between thecomponents FIG. 3 shows the twoconnected components second section 23 having been transformed in this state due to the material liquefaction and being no longer identifiable in its original form. - In the depicted example, the
second component 5—particularly with the raisedarea 31—overlaps over theannular area 29 of thesection 6 connecting radially on the inside to thesecond component 5, so that the annular area and hence thesection 6 as well are preferably also held axially in a positive fashion. - The
recess 20 and theprojection 21 preferably extend at least substantially peripherally around thesection 6 or the pump chamber P in the depicted example, especially preferably in a continuous or, as needed, interrupted manner or in sections or sectors. Accordingly, a good and tight connection can be achieved via this peripheral or longitudinal stretch. - In the following, other embodiments are explained on the basis of the other figures. In so doing, particularly, only substantial differences or additional aspects are explained. In particular, the previous explanations are applicable in a complementary or corresponding manner.

However, other courses are also possible. - It is through the
channel 30 that the material 31 (the same plastic or another plastic such as the first and/orsecond component components material 31 also fills the lateral space between theprojection 21 and side walls of therecess 20 at least in part.

channel 30 can also be designed in the shape of a slit, at least in the area of its opening end facing the bottom 24.

first dispensing chamber 35 which is fluidly connected with theconnector 34, an optional narrowing orthrottle 36 adjacent to thefirst dispensing chamber 35 and/or asecond dispensing chamber 37 adjacent thereto to which thenozzle 14 connects. - In the depicted, preferred two- or multiple-part design, the dispensing
chambers nozzle 14 are each divided in two in bothcomponents nozzle 14 and/or of the narrowing 36 is only optional. - In the depicted example, the
liquid 2 to be dispensed (not shown) is able—particularly due to a corresponding propellant contained therein—to already expand somewhat in each of the two dispensingchambers nozzle 14. However, other constructive solutions are also possible here. In particular, theliquid 2 can also be dispensed in non-atomized form, for example as a stream of liquid. - It should be noted that various elements influencing the flow such as projections, narrowings, baffles, bridges or the like can be formed in the flow path—particularly in the dispensing
chambers device 1 or thecomponents - In the depicted example, the two
components FIG. 6 such that theprojection 21 engages in therecess 20. Namely, in the depicted example, the components preferably manufactured by means of injection molding are preferably connected with each other via anoptional connection 38 such as a bridge or a film hinge or the like. This permits a very simple and cost-effective, single-part manufacture. In particular, the later assembly is made considerably simpler, since thecomponents components - When the
projection 21 engages in or presses into therecess 20, a welding of thecomponents second component 5 and thesecond section 23 of theprojection 21 is melted under the ultrasound effect in order to connect or to weld theprojection 21 orfirst section 22 solidly and liquid-tightly and, particularly, gas-tightly with the wall of therecess 20 or to at least seal off existing gaps. - A tight connection of the two
components nozzle 14 of thedispensing device 1 is made possible. - Individual features and aspects of the various embodiments can often be combined with each other at will or be used in other dispensing devices or the like.
- In particular, the present invention is generally related to the liquid-tight connection of two pump parts or the like.
