Description
[0001] The present invention relates to a delivery device according
to the generic term of claims 1 or 16.
[0002] The term "delivery device" as used in the present invention
is to be understood particularly as a dosing pump, or a
hand-operated pump, respectively, for dispensing a preferably
cosmetic liquid. However, it may also be any other delivery device,
such as a container, delivery or spray head, dispenser, or such,
particularly for a cosmetic liquid.
[0003] The term "cosmetic liquid" includes in a narrow sense any
personal hygiene and cleansing product, cosmetics, or such.
Generally, it may be a lotion, a gel, a suspension, or any other
liquid, optionally also a fluid having a gas phase, or such.
Technical liquids and fluids may also be considered. For reasons of
simplicity, however, and due to the utilization aspect, reference
is often made only to a cosmetic liquid in the following.
[0004] EP 0 442 858 A2 discloses a delivery device having a base
part and an elastic upper part. A pump chamber is embodied between
the upper part and the base part. By pressing down on the upper
part, or at least on an actuating section of the upper part, a
liquid can be displaced and dispensed from the pump chamber.
Subsequently, a self-actuated, elastic resetting of the upper part,
or of the actuation section, respectively, occurs, wherein fresh
liquid is suctioned into the pump chamber. It is difficult to find
a suitable material for the upper part in order to obtain the
desired features--particularly a high chemical stability and high
resetting forces.
[0005] DE 1 934 235 U discloses a similar delivery device, wherein
an upper part that can be elastically deformed is embodied in an
approximately hemispherical manner, and has radial reinforcing ribs
on the outside for increasing the resetting force, which end in an
annular bulge on the head of the upper part. The annular bulge
simultaneously serves for guiding a finger when pressing down on
the upper part. The correct choice of material for the upper part,
or for achieving the desired properties, also proves problematic in
this case.
[0006] WO 01/34485 A1 discloses a delivery device having a pump
chamber that can be elastically deformed, which is inserted in a
separate compartment for the elastic resetting of the pump chamber.
In this case the production is more extensive as opposed to the
previously mentioned prior art, due to the separate compartment.
Furthermore, the problem exists that a sufficiently chemically
resistant material for the liquid to be pumped must be found both
for the compartment and for the walls of the pump chamber.
[0007] The present invention is based on the task of providing an
improved delivery device, which particularly also enables the
delivery of higher viscous or paste-like liquids, or products,
and/or an improvement of the elastic properties, such as the
resetting, and/or improved protection of a component or material
that in particular can be elastically deformed, preferably against
the liquid, with a simple and cost-effective construction.
[0008] The above task is solved by means of a delivery device
according to claims 1 or 16. Advantageous further embodiments are
the object of the sub-claims.
[0009] One aspect of the present invention is to combine a wall, or
another section of the component--preferably in the area of a pump
chamber, and/or of another area that in particular can be
elastically deformed, and/or an area contacting the liquid--with an
element comprised of a second material. This allows for
substantially greater constructive freedoms and a greater freedom
in the choice of materials with a simple construction, or simple
assembly of the delivery device.
[0010] The element, or the material, respectively, can improve or
modify the elastic or resetting properties of the component, and/or
protect the same from chemical or other influences.
[0011] A further aspect of the invention, which can also be
realized independently, is the covering of the wall, or of the
first material, by means of the element, or the second material,
respectively, preferably on the liquid side. In particular,
according to a preferred embodiment variation the element, or the
second material, respectively, forms a continuous material layer or
cover of the component, of the wall, or of the first material,
respectively, particularly at least in the area of the pump
chamber, and/or of another surface area that is in contact with the
liquid. In this manner the first material can be protected from
chemical and/or other influences, and/or an undesired contact of
the liquid with the first material can be avoided. Accordingly,
such materials, which are usually not suitable for the liquid, or
cosmetics, or for food, or are not approved for such, may also be
utilized as the first material.
[0012] According to another preferred embodiment the element does
not cover the wall comprised of the first material completely--at
least in the area of the pump chamber. In particular, the element
has arched, and/or rib or bar-shaped sections extending across the
wall. In this manner, a particularly optimal or desired resetting
or elasticity of the component can be achieved.
[0013] The element is preferably directly injected or molded onto
the component, or onto the wall thereof. This enables simple
production, for example, by means of so-called "bi-injection," e.g.
particularly by means of extruding in the same extrusion mold, in
which the wall, and optionally additional areas of the component
are produced.
[0014] Further advantages, features, characteristics, and aspects
of the present invention are obvious from the following description
of preferred embodiments based on the drawings. They show:
[0015] FIG. 1 a schematic cross-section of a proposed delivery
device according to a first embodiment;
[0016] FIG. 2 a schematic cross-section of a proposed delivery
device according to
[0017] FIG. 3 a schematic cross-section of a component and of a
base part of the delivery device according to a third
embodiment;
[0018] FIG. 4 a schematic perspective top view of a component of
the delivery device according to a fourth embodiment; and
[0019] FIG. 5 a schematic perspective bottom view of a component of
the delivery device according to a fifth embodiment.
[0020] The same reference symbols are used for the same or similar
parts in the merely schematically illustrated figures not drawn to
scale, wherein respective or comparative properties and advantages
are obtained, even if a repeat description is omitted.
[0021] FIG. 1 illustrates a first embodiment of a proposed delivery
device 1 for delivering a preferably cosmetic liquid 2 in the sense
stated above. The liquid 2 may be substantially more viscous than
water, or may optionally even be porous.
[0022] A container 3 is preferably associated with the delivery
device 1 for supplying the liquid 2, to which the delivery device 1
is detachably connected, if required. In this manner, an exchange
of the container 3 and/or a refilling of the liquid 2 can be
accomplished, if desired. As an alternative, the delivery device 1
may also form a reservoir for the liquid 2 or for the
container.
[0023] The delivery device 1 has a base part 4 and a component 5,
particularly an upper part. In the illustration according to FIG. 1
the terms "base part" and "upper part" correspond the preferred
arrangement or alignment of the delivery device 1 during normal
use. However, this is not necessarily the case. Accordingly, the
base part 4 and the component, or upper part 5, may also be
positioned to each other in any spatial alignment, or aligned with
each other, depending on requirement, use, embodiment, and
such.
[0024] The base part 4 is preferably embodied in a rigid manner,
and/or integrally formed, and is particularly injected or molded
from a suitable synthetic material.
[0025] The component 5 is embodied in an elastically deformable
manner. The proposed embodiment of the component 5 will be
explained in further detail below.
[0026] The delivery device 1 further has a receiving or pump
chamber 6 for the liquid 2, which in particular is formed or
limited exclusively in front of, or between the component 5 and the
base part 4.
[0027] Preferably, the component 5 forms an inlet valve 7 and/or an
outlet valve 8 optionally together with the base part 4. However,
the valves 7, 8 may also be embodied separately. The functionality
of the pump is enabled preferably due to the valves 7, 8. The
valves 7, 8 are preferably embodied as self-locking one-way
valves.
[0028] When the pump chamber 6 is filled with liquid 2, as
illustrated in FIG. 1, the volume of the pump chamber 6 can be
decreased by means of deforming the component 5, and thus the
liquid 2 can be displaced from the pump chamber 6 and dispensed.
Particularly for this purpose, an optional actuating element 9 is
preferably is pressed down manually in the direction of the arrow
N, and thus at least one actuating section 10 of the component 5.
However, it is also possible, for example, that a user (not
illustrated) presses the component 5, or the actuating section 10
directly for the dispensing of the liquid 2.
[0029] The displaced liquid 2 is delivered, or dispensed via the
outlet valve 8. The opening of the outlet valve 8 is particularly
carried out in a self-activated manner, preferably due to the
liquid pressure, and/or possibly in addition--as a result of a
respective displacement of the component 5 while pressing down.
[0030] Due to the proprietary elasticity or resetting force of the
attachment section 10, or the component 5, a self-activated
resetting according to arrow R then occurs after letting go into
the initial position shown in FIG. 1, wherein fresh liquid 2 is
received, particularly suctioned, into the pump chamber 6 via the
inlet valve 7. Opening the inlet valve 7 during the resetting
process is preferably carried out as a result of the low pressure
that is then prevalent in the pump chamber 6. The elasticity or
resetting force of the component 5 is adjusted to the viscosity
and/or the flow resistances in order to ensure an adequately quick
and/or safe resetting, and thus renewed filling of the pump chamber
6. The outlet valve 8 remains closed during the resetting or
renewed filling of the pump chamber 6.
[0031] The component 5 preferably has an at least substantially
circumferential annular section 11 that particularly forms the
inlet valve 7 and/or the outlet valve 8.
[0032] The annular section 11 is preferably radially supported from
the outside and/or inside at least substantially across its entire
peripheral extension from the base part 4. However, the annular
section 11 can be elastically deflected toward the inside at least
in sections, namely at least in the area of an inlet opening 12
preferably embodied in the base part 4. In the non-deflected state
the annular section 11 overlaps and closes the inlet opening 12.
When resetting the component 5, or with the suctioning of liquid 2,
respectively, the annular section 11 is deflected due to the liquid
pressure created in the inlet opening 12, and the inlet opening 12
is thus opened for the liquid 2. The annular section 11 therefore
forms the inlet valve 7 together with the base part 4, or the inlet
opening 12 in the illustrated example.
[0033] The annular section 11 is preferably embodied at least
substantially in the manner of a hollow cylinder. The radial
thickness of the annular wall is preferably decreased, or tapered
toward the free axial end thereof.
[0034] As an alternative, or additionally, the annular section 11,
however, may also be equipped with a through hole, a recess, an
axial slot, or such, in order to form a desired passage, and/or to
enable a desired, particularly radial deflection or
deformation.
[0035] For supply the liquid 2 the delivery device 1 in the
illustrated example preferably has a connector 13 with a suction
hose 14, or such, which is connected thereto, and extends to the
container 2. Preferably, the connector 13 is integrally molded to
the base part 4.
[0036] The outlet valve 8 is preferably arranged diametrically
opposite of the inlet valve 7 with respect to the axis of the
annular section 11. The annular section 11 is radially supported on
the inside in the area of the outlet valve 8, preferably by means
of a wall section 15 of the base part 4. In particular, the wall
section 15 is preferably formed by means of an inner elevation of
the base part 4 in the pump chamber 6.
[0037] In order to form the outlet valve 8 the annular section 11
radially overlaps an outlet opening 16 on the outside that is
formed in the wall section 15. In particular, the annular section
11 is elastically pre-stressed against the outlet opening 16--e.g.
radially toward the inside--or overlaps the outlet opening 16 at
least in a loose manner.
[0038] When activating, or pressing down on the component 5, or the
actuating section 10, particularly in the pressed down direction N,
any liquid 2 present in the pump chamber 6 is pressurized so that
the same radially deflects the annular section 11 in the area of
the outlet opening 16 toward the outside, thus opening the outlet
valve 8, and enabling the dispensing of the liquid 2, particularly
via a, for example, trunk-like dispensing channel 17, that is
connected thereto.
[0039] Subsequently the outlet valve 8--particularly due to the
self-elasticity or resetting force of the annular section 11--is
again at least substantially completely closed.
[0040] In the illustrated example the valves 7, 8 at least
substantially open and close by means of axial movements or
deflections, or deformations of the annular section 11, and/or at
least substantially perpendicular to the main actuating direction,
or the pressing down direction N of the component 5, or of the
actuating section 10. However, other arrangements are also
possible.
[0041] The dispensing of liquid 2 by means of the delivery device 1
is particularly carried out in the non-atomized state. However,
generally the atomizing of the liquid 2 is also possible by means
of the delivery device 1.
[0042] The delivery device 1 preferably has a connecting part 18
for supporting the component 5, and particularly for connecting the
component 5 to the base part 4. In particular, the connecting part
18 is embodied substantially in the manner of a bushing and/or
rigid--at least in comparison to the component 5. In a particularly
preferred manner the connecting part 18 is integrally molded
directly onto the component 5, particularly by means of so-called
"bi-injection," e.g. injection of another material onto a first
material. In a particularly preferred manner the component 5 is
peripherally circumferentially supported or held on the connecting
part 18.
[0043] Preferably, the base part 4 is inserted into the connecting
part 18, such as glued in, clamped in, or engaged.
[0044] However, it is also possible that the component 5 is
connected directly to the base part 4 only, or is held at the base
part 4 preferably at least in a self-sealing and/or self-supporting
manner. If necessary, undercut sections, snaps, or such may also
engage with each other for the connection.
[0045] Until recently, the component 5 has been produced in one
piece of a single material. According to the invention, however,
the component 5 is modified particularly as disclosed below, and/or
in the claims.
[0046] In the illustrated example the component 5 preferably forms
a continuous, particularly arched wall 19 at least in the area of
the pump chamber 6. The wall 19 particularly forms the primary
deformable area, particularly the actuating section 10, of the
component 5. In the illustrated example the component 5, or the
wall 19, is embodied preferably in dome-shaped or spherical manner,
particularly in a hemispherical manner. However, other shapes
and/or other uses of the component 5, such as for container walls,
valve parts, spring sections, or such--depending on the
application--are possible.
[0047] The wall 19 is comprised of a first material. Preferably,
the component 5 is comprised at least substantially of this first
material, particularly also the other sections, or areas thereof,
as the annular section 11 in the illustrated example, but
alternatively, or additionally, also other integrally molded
one-piece sections, such as valve tabs, supports, holding sections,
flange sections, reinforcements, or such.
[0048] According to the invention the component 5 is equipped with
an element 20 made of a second material, particularly at least in
the area of the pump chamber 6, or of the wall 19. In the first
embodiment according to FIG. 1 the element 20 is integrated in the
component 5, or the wall 19, particularly injected into the first
material, or extrusion-coated by the same.
[0049] The element 20 in this case is embodied, for example, in a
plane, fiber-like, or grate-like manner. Preferably the element 20
is also produced by means of injection molding, or in another
suitable manner.
[0050] The component 5 is preferably injection-molded. The first
material is preferably a synthetic material, particularly an
elastomer and/or a thermoplastic material. However, it may
generally be any other material. This applies in particular, if the
component 5 does not (only) form the wall 19 for the pump chamber
6, or another pump part, but another component of the delivery
device 1.
[0051] The first material is preferably an elastomer, rubber, or
another thermoplastic material. TBE (thermoplastic elastomer), TPV,
TEEE (thermoplastic elastomers having ether and ester groups), or
TPO (thermoplastic urethanes) are preferably used.
[0052] Preferably, the second material is also an elastomer and/or
a thermoplastic material, however, if necessary, it may also be any
other material.
[0053] In a particularly preferred manner the second material is a
polyolefin, particularly PP (polypropylene) or PE
(polyethylene).
[0054] It should be noted that the first material and the second
material are different, e.g. at least have different properties
and/or at least different compositions. By combining different
materials, the desired properties of the component 5 can be
achieved substantially more easily, for example, in the area of the
wall 19, or in the area for the pumps that can be elastically
deformed.
[0055] In the first embodiment according to FIG. 1 the element 20
particularly serves for optimizing the elastic properties of the
component 5, or of the wall 19, particularly of the elastic
resetting. Due to the integration into the first material, or into
the wall 19, the second material does not have any contact with the
liquid 2. Accordingly, a material optimal for the elastic
properties can be used independently of the chemical resistance
thereof as opposed to the liquid 2.
[0056] The element 20 is permanently connected to the component 5,
or to the wall 19 thereof. As an alternative to the
injection-molding, the element 20 itself may also be injected or
molded on, or vice versa, the wall 19 may be injected or molded
against the element 20, particularly preferably by means of the
previously mentioned "bi-injection" process. As an alternative, the
element 20 can generally also be connected to the component 5 or
the wall 19 by means of gluing, welding, or another suitable
manner.
[0057] A second embodiment of the delivery device 1 according to
the invention is explained below based on FIG. 2, which shows a
schematic cross-section according to FIG. 1. Only essential
differences as opposed to the first embodiment are highlighted. The
previous embodiments and explanations apply accordingly, or at
least in supplement.
[0058] In the second embodiment the first material of the component
5 is preferably completely covered by the second material in that
area, which is or comes in contact with the liquid 2. In
particular, the element 20 therefore forms a continuous cover, or
layer, or coating of the second material. The second material, or
the layer, is connected to the first material preferably in a firm,
non-detachable, and/or holohedral manner. For this purpose the
second material may be injected or molded onto the first material
by means of so-called "bi-injection," wherein the first material
may have or may form an at least substantially smooth or rough
surface, or a surface with undercuts, recesses, through holes, or
such. As an alternative the element 20, or the material layer,
respectively, may be connected to the first material, or may be
supported by the same only in sections--such as in edge or
circumferential areas. Alternatively, a mechanical, particularly a
positive-fit or form-fit connection is also possible in addition to
a chemical connection of the two materials. As an alternative, the
element 20 may also form only a particularly membrane-like part
that is inserted, or arranged between the liquid 2 and the
component 5. According to an alternative that is not illustrated,
the second material may also form a bushing, which preferably
surrounds the first material completely. In this case a direct
connection of the two materials is also not necessary.
[0059] The arrangement of the second material, or the cover of the
first material on the liquid side, or on the inside protects the
first material from chemical influences, particularly by means of
the liquid 2, and/or the liquid 2 from chemical influences by the
first materials, or any other interactions. In this manner it is
possible to utilize non-food safe materials and/or materials not
resistant to the liquid 2 as the first material in order to, for
example, achieve a cost-effective production and/or certain
mechanical or other properties. The second material can then meet
the required food safety or resistance with regard to the liquid
2.
[0060] In the illustrated example the element 20, or the second
material, respectively covers the surface of the wall 19 facing the
pump chamber 6, the inside, outside, and the front surface of the
attached annular section 11, and the radially attached annular area
of the annular flange 24 of the component 5. In particular, the
second material, or the layer or cover formed thereof, extends to,
or even underneath a material or component that is otherwise
resistant to the liquid 2, or that is inert, e.g. the base part 4,
or the connecting part 18 in the illustrated example.
[0061] In addition to the shielding of the first material, the
second material, or the element 20, respectively may also serve for
a modification of the elastic properties or other properties of the
component 5.
[0062] It should be noted that in the present invention elastic
properties and resetting generally are also to be understood as the
deformation of the component 5 in particular as an essential
property, or a property associated therewith.
[0063] The present invention, however, is not limited to elastic,
or flexible, e.g. particularly deformable components. Rather, the
cover via the second material may generally also by utilized with
any type of component of a delivery device 1 in the sense of the
present invention, particularly in order to prevent a direct
contact between the liquid 2 and the material.
[0064] Additional embodiments of the component 5 modified according
to the invention based on FIGS. 3 to 5 are explained below,
wherein, however, only substantial differences are highlighted. The
previous embodiments and explanations therefore apply accordingly,
or in supplement.
[0065] In the third embodiment according to FIG. 3 the element 20
is arranged on the side of the component 5, or of the wall 19
opposite of the pump chamber 6--e.g. on the outside. In this case,
the element 20 is embodied particularly as a continuous material
layer, or cover. Preferably, the element 20 is directly injected or
molded onto the first material, particularly by means of the
so-called "bi-injection" or such. The element 20 in turn serves
particularly for optimizing the resetting properties, particularly
in order to be able to achieve a sufficiently great resetting
force. Alternatively, or additionally, the element 20 can protect
the component 5, particularly the wall 19, or the actuating section
10, from mechanical or other influences.
[0066] Alternatively, or additionally, the cover formed by the
element 20 can also prevent the escape of plasticizers from the
first material in order to ensure the desired material properties
of the first material.
[0067] According to an embodiment variation that is not
illustrated, the element 20 may additionally be arranged on the
side of the component 5, or of the wall 19, facing the pump chamber
6--e.g. on the inside. In this case the element 20 can protect the
first material from chemical influences--particularly by means of
the liquid 2--alternatively, or additionally to the previously
mentioned properties, or effects. For example, it is possible to
optimize the first material with regard to its elastic properties,
or resetting properties, or to optimally choose the same regardless
of the chemical resistance or other properties thereof.
[0068] Preferably, the material being or coming into contact with
the pump chamber 6, or the liquid 2--e.g. the first and/or second
material--is food safe and/or at least chemically resistant to a
sufficient degree.
[0069] The element 20 is preferably connected to the wall 19 in a
holohedral manner. However, it is generally also possible that the
element 20 is connected to the wall 19 only in sections, for
example, only along welding lines.
[0070] FIG. 4 illustrates a fourth embodiment of the component 5
according to the invention. The element 20 is arranged on the
outside of the wall 19. The element 20 does not cover the wall 19
completely, and is therefore not embodied continuously, but instead
is equipped with through holes or openings in particular. In the
illustrated example the element 20 particularly has rib or bar-like
sections 21, which connect an inner ring 22 to an outer ring 23 of
the element 20--preferably radially and/or having an arched
progression. The desired resetting behavior can be realized very
easily by means of respective adjustment, such as of the number,
cross-section, width, height, course of the sections 21, the
dimensioning of the inner ring 22 and/or of the outer ring 23,
selection of a respective material, and such.
[0071] The outer ring 23 is preferably connected to an annular
flange 24 of the component 5 on the axis side in a holohedral
manner, wherein the same is radially attached to the wall 19.
[0072] Additionally, the ring 22, or any other area of the wall 19
that is optionally reinforced or covered by the element 20 may form
the actuating section 10, or abutment or support for the actuating
element 9.
[0073] FIG. 5 illustrates the bottom view of a fifth embodiment of
the component 5 according to the invention. In this case the
element 20 is arranged on the side facing the pump chamber 6--e.g.
the inside--and is preferably embodied according to the third
embodiment.
[0074] Individual characteristics and constructive solutions of the
embedment and of the stated embodiment variations explained may
also be combined with each other and/or utilized in other delivery
devices.
