Definitions

  • the invention relates to a discharge head for a massage dispenser and a massage dispenser with such a discharge head.
  • Generic as well as inventive massage dispensers are characterized in that they have a liquid reservoir in the usual way of dispensing, the liquid contained therein can be discharged through an outlet opening.
  • the peculiarity of a massage dispenser is that the discharged liquid is discharged in the area of a massage surface which is profiled to massage the discharged liquid into the skin of the user.
  • the liquid can be discharged onto the massage surface in a first step and then rubbed into the skin from there.
  • it can be discharged onto the massage surface while the massage surface is already pressed against the skin of the user.
  • the object of the invention is to provide a massage dispenser and a discharge head for such a massage dispenser, which enable particularly pleasant and convenient operation.
  • a discharge head according to claim 1 and a massage dispenser with such a discharge head according to claim 13 are proposed.
  • a discharge head according to the invention is designed for attachment to a liquid reservoir.
  • it has a base section with a receptacle for stationary coupling to an outlet section of the liquid storage device.
  • the receptacle can be designed, in particular, as a receptacle shaft into which the outlet section of the liquid reservoir is inserted in the coupling direction in order to be secured therein by a latching connection or clamping connection become.
  • a thread can be provided, in which case the central axis of the thread forms the coupling direction.
  • the discharge head has a massage section.
  • This has the aforementioned massage surface, which serves the purpose of rubbing or massaging the liquid by pressing it against a user's skin.
  • This massage surface is penetrated by at least one outlet opening, so that liquid can be discharged from the liquid reservoir directly onto the massage surface and can then be rubbed in from there.
  • the liquid which is discharged with a discharge head according to the invention is preferably highly viscous, in particular in the form of a cream or a gel.
  • cream and gel are used synonymously in the sense of this invention and similarly describe a liquid which has a viscosity of at least 500 cP when stored.
  • the above-mentioned rubbing in or massaging takes place using a massage profile on the massage surface.
  • the profiling is considerable in order to create, as it were, small buffers for the liquid through their depressions, so that the liquid is not completely stripped off the surface when it is moving.
  • the profiling leads to locally varying pressure when the massage surface moves over the skin, which brings about the desired massage effect.
  • Alternative massage profiles have a plurality of concentric circular elevations or depressions or at least one, in particular circular or oval, elevation which delimits the massage surface on the outside.
  • the massage surface preferably has an essentially round or oval shape in the direction of its central normal vector. Their area is comparatively large in order to be able to treat larger areas of skin well.
  • the smallest expedient size is 0.5 cm 2 and the largest expedient size is regarded as 20 cm 2 , the size specifications each relating to the area between the at least one outlet opening on the inside and the outside outer edge of the massage area.
  • a size of at least 1 cm 2 and at most 10 cm 2 is particularly preferred.
  • the massage surface can be rigid in itself, so that there is no significant shift in relation to other parts of the massage section and in particular the parts of a pump device which will be discussed below.
  • the massage surface is designed to be deformable. It can then assume a concave and a convex shape, depending in particular on a contact pressure.
  • the massage section as a whole, together with the outlet opening and the massage surface, is movable relative to the base section in a main direction of extension of the discharge head.
  • This mobility is given between two end positions, a distal end position and a proximal end position, it being possible for the distal end position to be adjustable, as will be explained further below.
  • the main direction of extension in the direction in which the mobility is given, is preferably identical to the direction of coupling of the receiving shaft.
  • the mobility can be a purely axial in the main direction of extension or a mobility that is given axially and rotatively.
  • the axial mobility of the massage section relative to the base section serves to actuate a pump device of the discharge head.
  • This pump device has a volumetrically variable pump chamber and an inlet valve and an outlet valve, the inlet valve preferably being provided on the base section and the outlet valve preferably being provided on the massage section.
  • the inlet valve is provided in a connecting channel between the pump chamber and the liquid reservoir or the receptacle for the liquid reservoir.
  • the outlet valve is provided in a connecting channel between the pump chamber and the outlet opening.
  • the valves are intended for the typical interaction of pumps. This means that the inlet valve opens at a negative pressure in the pumping chamber in relation to the liquid storage, which is synonymous with excess pressure in the liquid storage in relation to the pumping chamber. If there is excess pressure in the pump chamber, the inlet valve closes.
  • the outlet valve opens when there is sufficient overpressure in the pump chamber against an ambient pressure and closes when there is underpressure. The size of the overpressure for opening the exhaust valve is explained below.
  • valves can each have different designs.
  • the valves as a whole can have movable rigid valve bodies, such as valve balls, which are movable in a valve chamber of their respective section between a closed position and an open position.
  • the valves can have an elastic valve section which is fixed in sections to the respective section and which can assume an open position or a closed position through a valve slot or a valve flap.
  • the pump chamber is volumetrically variable in that the massage section is shifted between the end positions mentioned relative to the base section.
  • the pump chamber is at least delimited by walls of these two sections, so that their displacement in the direction of the proximal end position causes a change and, in particular, a reduction in the pump chamber volume.
  • the walls of the base section and the massage section, which directly delimit the pump chamber can be rigid parts, in particular plastic parts. However, it can also be wholly or partly elastically deformable parts, for example in the case of a design with a pump bellows or in the case of elastically deformable sealing lips or sealing rings.
  • the maximum amount of liquid that can be discharged with a stroke from the distal end position to the proximal end position is comparatively large in the case of a massage dispenser according to the invention, since enough liquid is to be discharged with one stroke in order to be able to cover the entire massage area with a liquid film.
  • This maximum amount of liquid due to the maximum stroke can be at least 0.5 ml, preferably at least 1 ml, particularly preferably at least 2 ml.
  • the two named sections, the base section and the massage section movable relative thereto, can each be formed in one piece. However, they can also each comprise several components that are firmly connected to one another. This can be particularly expedient in order to be able to combine different massage surfaces with an otherwise identical massage section, to obtain sections with more easily deformable characteristics, for example to form a sealing lip, and / or to form a valve body cage for receiving a rigid valve body.
  • a discharge head according to the invention and a massage dispenser with such a discharge head are distinguished by simple and pleasant operation.
  • the provision of a pump device leads to the discharge of constant amounts of liquid or, depending on the configuration, adjustable amounts of liquid.
  • the pump device can also convey liquids of very high viscosity by means of a slide guide, which will be described below.
  • the discharge itself can be achieved by manual handling of the massage section and / or by pressing the massage section onto the skin.
  • the massage surface is provided with profiles in the manner described above. If these profiles are disregarded, the basic shape of the massage surface is preferably flat, which means that the height variation in the direction of the mean normal vector between them opposite outer edges of the massage surface is a maximum of 1/5, in particular a maximum of 1/10, of the maximum distance of the outer edges of the massage surface orthogonal to the mean normal vector.
  • This flatness is advantageous for most fields of application, for example for the application of the liquid to the arms, legs and back of a user.
  • a different shape in particular a clearly convex shape, can also be useful.
  • the mean normal vector on the massage surface preferably coincides completely or largely ( ⁇ 5 ° deviation) with the main direction of extension. This leads to a small design and a particularly advantageous possibility of emptying the pump chamber by pressing the massage surface against the skin in the direction of the normal vector. However, this type of operation is also possible at a larger angle between the main direction of extension and the mean normal vector, in particular of up to 30 °.
  • This design of the pumping device allows the pumping chamber to be enlarged volumetrically for the purpose of the subsequent discharge, first by displacing the massage section relative to the base section in the direction of the or a distal end position, in order to thereby cause a filling.
  • the pump chamber then remains in the filled state until external force causes the transfer of the massage section in the direction of the proximal end position and thereby reduces the size of the pump chamber, so that the liquid contained therein is conveyed through the outlet opening onto the massage surface.
  • the waiver of an automatic reset is also advantageous because a corresponding pump spring complicates the stroke movement taking place against the spring force.
  • this spring force would make it even more difficult. It is therefore preferred if no pump spring is provided.
  • the pump chamber can be enlarged primarily by pulling the massage section in the direction of the distal end position by means of a manually applied tensile force, the pump chamber being filled with liquid.
  • pressurizing the liquid in the liquid reservoir can force it into the pumping chamber. This procedure is possible, in particular, for tubes as a liquid store.
  • a special design of the exhaust valve is proposed, which will be explained further below.
  • the discharge by reducing the pump chamber volume can be done with purely axial mobility by manually moving the massage section in the direction of its proximal end position.
  • a superimposed axial and rotary mobility can also be provided, which is also understood as mobility in the main extent in the sense of the invention.
  • the discharge head in particular can have a link guide with link track and link slide, one of the above-mentioned link elements being provided on the base section and the other on the massage section.
  • the sliding guide enables the pump chamber volume to be increased or reduced by the guided movement of the massage section relative to the base section in the superimposed direction of rotation and main direction of extension.
  • the massage section has a handling surface on the outside for coupling in a torque with respect to the base section, in particular with a profiling for easier rotation.
  • the superimposed movement with a link track is particularly suitable for highly viscous liquids, where a purely axial solution would require too much traction.
  • the user can enlarge and reduce the pump chamber by rotating the massage section relative to the base section, which indirectly causes an axial movement and thus influences the pump chamber volume.
  • More complex designs of the link track such as that of a sawtooth shape, can also enable handling in which the pump chamber can be enlarged and reduced in size by separate partial movements, in the case of a sawtooth shape, for example, an enlargement of the pump chamber by superimposed rotary-axial movement and a reduction in the size of the pump chamber through purely axial movement.
  • the direction of extension of the link track with the main extension direction includes a large angle close to 90 °, this causes self-locking between the link slide and the link track, so that the indirect causing of a rotational movement by applying force to the massage part in the main direction of extension relative to the base section is prevented. This can be desirable in order to cause an unwanted change in the pump chamber volume.
  • a design is particularly advantageous in which a holding section is provided on the massage section, which mechanically secures the inlet valve on the base section against opening in the proximal end position from massage section to base section.
  • This holding section preferably protrudes into the pump chamber, so that it blocks the mobility of a valve body or elastic valve section of the inlet valve in the proximal end position.
  • the massage section and the base section can be advantageous if the massage section and the base section relative to one another in a specific position, in particular the proximal end position, about a central axis is rotatable between at least two rotational positions.
  • the massage section and the base section can be provided with interacting profiles, which, depending on the rotational position, prevent axial relative mobility of the massage section and the base section in the main direction of extension and / or limit the stroke distance between the proximal end position and the distal end position.
  • the profiles mentioned can comprise axially extending grooves of different lengths, for example in the base section, and a cam engaging therein, for example on the massage section. If the cam is arranged in one of the grooves, this groove determines the maximum stroke, in particular by defining the distal end position by its length.
  • the user can select one of the grooves by rotating the massage section relative to the base section and thereby adjust how long the stroke should be. In this way, he can specifically control the amount of liquid that is discharged by displacing the massage section relative to the base section.
  • the profiling can also be designed with only one axial groove, which thus only defines a distal end position.
  • the said rotatability can then be provided solely to prevent the movement of the massage section relative to the base section in the proximal end position by introducing a profiling cam into a circumferentially extending groove section which adjoins the axial groove and thus to secure the dispenser.
  • the outlet valve opens when there is overpressure in the pump chamber and closes when there is underpressure.
  • no spring means or the like is required on the outlet valve, since the pressure difference alone is sufficient to press a valve body into a corresponding open position or closed position.
  • the outlet valve is subjected to a force in the direction of its closed position by means of a spring means, so that a certain minimum discharge pressure of the liquid in the pump chamber is required in order to convey liquid from the pump chamber to the outlet opening.
  • guidance between the base section and the massage section is to be made sufficiently smooth that the base section and the massage sections can be transferred from the proximal end position to the distal end position by an expansion pressure that is lower than the minimum discharge pressure.
  • Such a design allows the pumping chamber to be filled solely by excess liquid pressure in the liquid reservoir.
  • This excess liquid pressure can be achieved, for example, by squeezing a squeeze bottle or a tube. If this pressure is above the expansion pressure defined by the discharge head, but below the minimum discharge pressure of the outlet valve, the indirect pump chamber is filled in the desired manner.
  • the outlet valve is preferably designed in such a way that even after reaching a completely filled pump chamber and arranging the base section and massage section in the distal end position, there is little risk of it being inadvertently discharged through the outlet valve by pressurizing the liquid in the liquid reservoir.
  • it is preferably designed in such a way that it remains closed up to an excess pressure of at least 0.1 bar with respect to the ambient pressure. An overpressure of 0.1 in a tube is usually not accidentally caused when the tube is gripped.
  • Exhaust valves that are even more difficult to open can be expedient, for example up to an excess pressure of at least 0.2 bar, at least 0.5 bar or at least 1.0 bar, closed exhaust valves.
  • An overpressure of 0.5 bar, for example in a tube can usually only be achieved willfully, so that a high degree of safety is achieved as a result.
  • the discharge head preferably has a cap for repeated removal and replacement.
  • This cap can be attached to the base section by means of a clamping surface or a detent or thread profile.
  • such a cap can take on additional functions. In the attached state, it can close the at least one outlet opening by means of a locking pin provided on the inside of the cap in order to prevent unwanted liquid discharge.
  • the cap is preferably dimensioned such that in the attached state and in particular in the delivery state it forces the massage section to be arranged in its proximal end position. In this position, the cap can hold the massage section in a relative position relative to the base section, in which, with a corresponding design, the massage section mechanically secures the inlet valve on the base section against opening. This can be done in particular by means of a holding section protruding into the pump chamber, as described above. In particular when the discharge head is designed without a slide guide, it is advantageous if the cap ensures the closed state of the inlet valve.
  • the cap is secured against removal by means of a tamper-evident tamper-evident portion.
  • the two main components of a discharge head according to the invention are the base section and the massage section.
  • the base section can have a circumferential groove into which an annular collar of the massage section is immersed when the massage section is displaced in the direction of the base section, this groove preferably being arranged surrounding the receptacle for the liquid reservoir.

  • the liquid storage device is preferably designed as a liquid storage device with a variable volume, in particular as a tube.
  • Other liquid reservoirs with variable volumes are, for example, those with a trailing piston or an inner bag in the liquid reservoir.
  • Such liquid stores make it possible to dispense with an aeration device for the liquid store, so that a simple construction is possible.
  • the aforementioned design with a tube also allows the liquid to be pressurized in the liquid store.

  • An annular seal is provided in the area of the guidance of the massage section 30 and the base section 50.
  • the displaceability of the massage section 30 relative to the base section 50 is in the configuration of the 4A to 4C no purely linear relocation. Rather, a helical section-shaped link track 40 in the manner of a groove is provided on the outside of the collar 34 of the massage section 30 and, corresponding to this, on the inside of the base section 50 a link slide 60 which projects into the mentioned link track 40. As a result, the massage section 30 can only be displaced in a helical movement relative to the base section 50.
  • the pump chamber 72 In order to discharge liquid, the pump chamber 72 is preliminarily filled.
  • the liquid reservoir 80 or the base section 50 is gripped with one hand and with the other the massage section 30 is rotated about the central axis 3, which at the same time causes the massage section 30 to move axially in the distal direction.
  • This enlarges the pump chamber 72 and draws liquid into the pump chamber 72 with the outlet valve 76 closed and the inlet valve 74 open.
  • FIG. 4B After an angle of rotation of about 50 °, the condition is Figure 4B reached.
  • a marking arrow 36 on the massage section 30 shows that a total of about 2 ml of the liquid was drawn into the pump chamber 72 from the liquid storage 80 at this point in time.
  • a continued rotation of another 50 ° leads to the state of the Figure 4C , In this state, the massage section is in its distal end position with respect to the base section 50.
  • the enlargement of the pump chamber 72 compared to the state of FIG Figure 4A is now about 4 ml and thus its maximum.
  • the user can effect the discharge by reversing the direction of rotation.
  • the reversal of the rotational movement and thus the beginning displacement of the massage section 30 in the direction of the base section 50 leads to the inlet valve on the base section closing and the outlet valve 76 opening on the massage section.
  • the liquid is then conveyed onto the massage surface 32, so that massage into the skin area can then begin.
  • the massage section 30 is shifted upwards, in particular in accordance with the desired discharge amount Figure 5C clarified.
  • the pump chamber 72 is filled with liquid from the liquid reservoir.
  • the massage section 30 is shifted downward relative to the base section 50, so that the desired discharge through the outlet opening 31 occurs when the inlet valve is closed and the outlet valve is open.
  • This design also allows the discharge not to be effected by manually depressing the massage section 30, but rather by pressing its massage surface 32 onto the skin area 204 and thus indirectly by applying force to the massage section 30 in the direction of its proximal end position relative to the base section 50 a well-dosed discharge is also possible, in which during a massage movement due to increasing approximation of the Massage section 30 in the direction of the proximal end position to the base section 50 or batches of liquid is discharged.
  • FIG. 5A illustrates how a cap 100 can be used to secure the discharge head 20 with such a purely axial mobility.
  • the cap 100 is secured in the position shown until the tamper-evident section 108 is separated.
  • After first use it is secured in the attached state by a locking cam 104 and a locking groove 66 provided for receiving it on the base section 50.
  • a locking cam 104 In the attached state, it presses on the valve ball of the outlet valve 76 via a locking pin 102 and thus presses the entire massage section including the holding section 38 downward.
  • the valve ball of the inlet valve 74 is also forced into its closed position.
  • the 6A and 6B show an alternative design, which as a variation to the design of the 5A to 5C can be seen.
  • a profile 64 with three axial grooves 64A, 64B, 64C is provided on the inside of an outer ring wall 57 of the base section 50, as in FIG Figure 6B to recognize. These grooves are connected to one another at the lower end by a transverse groove 65.
  • a control cam 44 which is provided on the massage section 30 and is directed outward is arranged within this groove structure. This has been inserted into the groove structure through the axial groove 64B. Due to a locking tongue arranged in the groove 64B, the control cam can no longer escape in the opposite direction through the groove 64B after overcoming the locking tongue during assembly.
  • the control cam 44 can, by being arranged at the lower end of one of the three axial grooves 64A, 64B, 64C, control how far the distal end position of the massage section 30 is spaced apart from the base section 50 from the proximal end position.
  • the choice of the rotational position of the massage section relative to the base section 50 can thus be used to control how large the maximum liquid discharge is.
  • the massage section 30 can be secured against axial displacement by arranging the control cam 44 in the transverse groove 65 of the base section 50. This is, for example, in the rotary position Figure 6A the case.
  • Fig. 7 only differs from that in one detail 5A to 5C ,
  • the outlet valve 76 is provided with a valve spring 77, as a result of which the pressure required to discharge liquid from the pump chamber 72 onto the massage surface 32 is increased.
  • an excess pressure in the pump chamber 72 of at least 200 mbar may be required to discharge liquid.
  • this makes it possible to fill the pump chamber 72 solely by compressing the liquid reservoir 80, namely when the pressure required for the displacement of the massage section 30 relative to the base section 50 is lower than the opening pressure defined by the outlet valve 76.
  • the outlet valve 76 is in a position by the valve spring 77 to usually prevent an inadvertent discharge by pressing the tube even when the pump chamber 72 is filled. Only when the tube is pressed together with great force is the pressure sufficient to inadvertently convey liquid through the outlet opening 31. If necessary, a cap can also be used to prevent the risk of unintentional discharge when not in use.
  • the 8 to 10 show alternative designs of the massage surface 32.
  • the massage surface 32 shown in the previous examples has a plurality of elevations, arranged in a honeycomb structure
  • Fig. 8 shows a likewise preferred embodiment in which the massage profile 33 is formed by concentric ring elevations and depressions between them.
  • Fig. 9 also shows such ring elevations and depressions, in this case, however, on a deformable massage surface, which can yield somewhat elastically in relation to the rest of the massage section 30 in order to be able to adapt even better to the body shape.
  • the variant of Fig. 10 has only one outside web as a massage profile 33.
  • All of the massage profiles shown are suitable for preventing the liquid present on the massage surface 32 from being wiped off immediately upon skin contact. They form local depressions which prevent this and thus advantageously allow the massaging in of liquid over a larger area.
