Abstract

The invention relates to a device for applying liquid substances. The inventive device consists of a handy housing. The outlet of said housing is designed for the substance and can be sealed by means of an elastic counterpressure. The sealing element (2) protrudes over the surface of the housing at the outlet and against the effect of a narrow pressure-, leaf- or annular spring (6) which clutches a symmetrically formed cage (4). The sealing element (2) can be moved backwards and is arranged in a dosing unit (9) that can be pre-assembled and comprises a closing flap (1). The cage (4) is provided with a step having an anvil surface (8) and can be moved in the longitudinal direction within a region that can be pre-determined. The substance to be applied thus leaves the container in the desired fine dose.

Description

Device for applying liquid substances

The inventions are based on a device according to the preamble of claims 1, 5, 7 and 12.

State of the art

From DE 38 35 299 Cl a dispensing device for flowable materials is known, which has a storage container with a storage space, which serves to hold the liquid. A mouthpiece with a closure element for applying the liquid is also provided. A plunger located in the storage container and mouthpiece can be moved longitudinally against the force of a compression spring both by the closure element and by deformation of a grip zone and can be lifted off the closure element. The opening of the closure element is associated with a closing of inlet channels which interrupt the connection to the storage room.

A similar device is known from DE 39 37 293 A1. It is particularly intended for the application of adhesives and has an inner housing sleeve for receiving a cartridge filled with the substance to be applied with an application tip arranged at the lower end of the inner housing sleeve with a spring-loaded ball valve and an outer sleeve with a sealing cap with a ventilation valve that can be moved axially over the inner housing sleeve ,

Both known devices have in common that the outlet opening for the substance to be applied is closed by an application ball projecting beyond the user interface and the application ball can be moved back against the action of a valve spring. The outflow of the substance is essentially constant.

Devices for applying liquid substances, so-called roll-on designs, are also known, in which the application takes place by means of a large ball. After use these devices must be closed with an end cap, which does not prevent the outer surface of the ball from drying and initially makes it difficult to roll.

If you have skin care products, e.g. B., pleasantly stimulating, relaxing and beneficial to the skin, skin functional oils, alcoholic-aqueous fragrant waters (e.g. colognes or toilet water), but also want to apply perfume mixtures with the scent-stimulating essences to the skin, you are primarily dependent on the hand.

task

The inventions specified in claims 1, 5, 7 and 12 are therefore based on the object of creating devices for applying flowable substances to the surface of human skin or the like according to the preamble of independent claims 1, 5, 7 and 12, with which it is possible is that the substance to be applied emerges from the container in a targeted manner and in the desired fine dosage.

Advantages of the invention

With the four devices according to claims 1, 5, 7 and 12 it is achieved that, depending on the application pressure, the substance to be applied flows out in the desired amount. In the case of very expensive substances, application can be carried out sparingly. Compared to all common (introduced) dispensing devices (with screw cap, spray bottle, roll-on version), a higher quality of operation is achieved because the automatic closure does not require a closing or sealing process due to an additional end cap. For everyday use, the bottle can be removed from the shelf and the desired amount of liquid can be applied directly to the skin without any action on the device. Then it can be switched off again without any manipulation on the self-closing device. However, the inventions also integrate the possibility of a fixed locking for the change of location and a fixed setting for a desired permanent minimum dosage amount without great effort. Pre-assembly is also advantageous the device into small units so that it can be fed into the highly automated filling systems, as with screw caps. The adjustable fine dosing of liquid substances opens up many applications, e.g. B. also the application of nail polish. The central opening brings the substances exactly to the desired location. This is particularly advantageous for stain removers. Since the known designs are usually disposable items, refilling by the consumer is not possible. Given the great demand and correspondingly large numbers of such devices, a considerable contribution to environmental protection and responsible use of resources would be achieved. The inventions can also be used as disposable items, but make more sense in the refill version. For this purpose, the adjustable fine dosing described can be used for a large area of application of liquid substances, not only economically in use, but also user-friendly.

embodiments

In the invention according to claim 1, a ball is used as a closure element in a manner known per se. The ball can be moved back against spring force, but in a predetermined range that enables fine metering.

With the embodiment according to claim 2 easy assembly of the components is achieved.

The embodiment according to claim 3 enables the exact adjustment of the dosage, which is preferred by the user and which does not have to be changed after use, because the opening is resiliently closed in all settings. Because of its handiness, the device is particularly suitable for taking with you on trips. In addition, an O position ensures a tight seal that prevents unwanted leakage of liquid. In addition, both the ball and the profiles exert an additional stimulus on the nerve endings susceptible to tactile stimuli, so that the correct dosage and the beneficial effects of the care products enhance the overall effect.

The development according to claim 4 offers the possibility of connecting various useful elements such as an additional container to the device.

In the invention according to claim 5, a completely different principle is used for the closure element. Depending on the pressure exerted on a flat application head, the closure element moves back against spring force.

The development according to claim 6 shows two ways in which the counter-movement of the closure element, in which the application head is moved relative to the closure element, can be realized. The advantage of the countermovement is that the substance can be applied over a large area, so that the application pressure is distributed over the skin. The gear ratio for the levers can be set by selecting the ring bar.

In the invention according to claim 7, a hose is used as the liquid supply, which is clamped to different degrees for dosing.

With the various clamping means according to the developments according to claims 8 to 9, clamping devices are obtained for which only a few parts are required, which makes the devices very suitable for mass production.

The configurations according to claims 10 and 11 enable the substance to be distributed even more easily and over the skin.

The fourth variant of the invention according to claim 12 does not require levers and clamps in order to realize the dosage for a desired permanent setting.

In the development according to claim 13 it is prevented that the outlet opening when using crusted ends Substances are clogged so that they are particularly suitable for the precise application of adhesives and stains

All devices are easy to handle when applying and dosing the substances, even if they are highly effective, expensive and / or highly adhesive materials.

In Fig.l the functional elements of the adjustable fine metering are enlarged in the area of their interaction and z. T. disassembled shown. The end cap 1 has a central bearing recess 3 for the application ball 2 which forms the outflow opening for the liquid. The bearing countersink 3 is preferably adapted to the spherical shape. If another sealing element is used instead of the ball, e.g. B. a pen with a rear enlarged approach, this also applies. Above it is the cage 4 with the grooves 5 through two eyelets 7 installed flat spring 6, which is curved in a circle. This forms an arc over a web-like anvil surface 8. In addition, it presses resiliently against the inner wall of the end cap 1 and prevents the cage 4 from falling out when the end cap 1 is removed. The arc height above the anvil surface 8 corresponds to the setting range in which the ball 2 against the Spring 6 can be moved back to the fixed limit. Further up, the lower region of the adjusting sleeve 10 can be seen, which acts on the upper edge of the cage 4 and can shift it minimally in the longitudinal direction towards or away from the central bearing depression 3 of the end cap 1, which is indicated by arrows.

Fig. 2 shows a metering setting of the anvil surface 8 with the outlet opening being resiliently closed by the application ball 2, in the rest position.

In Fig. 3 the position of use is shown, i.e. with the ball 2 pushed back during actuation, which promotes a liquid film to the outside by rolling on an object.

4 shows the fixed closed position of the anvil surface 8, in which no liquid can escape to the outside.

Fig. 5 shows the constructive execution of a combination for substance application and touch activation of the skin surface. Here, the tubular container 11 is connected at its rear end via a fine thread 12 to a connecting piece 14. The container 11 can also be designed so that a cartridge with the liquid to be applied can be used, which is automatically opened by a cutting device, not shown, when inserted into the container. The rear region of the adjusting sleeve 10 also opens into the connecting piece 14, so that the adjusting sleeve 10 is minimally displaced in the axial direction by rotating the end cap 1 relative to the connecting piece 14. To the Filling the liquid, the connector 14 is unscrewed and pulled out of the container 11 together with the adjusting sleeve 10. The container 11 also serves as storage for a plurality of profile bodies 13, which are rotatably arranged in the axial direction between the end cap shoulder 15 and the lower plane surface of the connecting piece 14 (FIG. 9). An elastic pendulum rod 32 is fastened to the connecting piece 14, which is explained in more detail in FIGS. 23 and 24.

6 shows a top view of the spring cage 4 with a flat spring (6) suspended in the grooves 5 on two eyelets 7.

Fig. 7 shows a spring variant as a small compression spring 16 which is mounted in a central extension of the anvil web 8 and presses a pressure pin 17 with the front flat surface against the ball 2. The non-slackening spring 16 ensures permanent use of the device.

In the plan view from below of the cage 4 according to FIG. 8, the front flat surface of the pressure bolt 17 can be seen.

Fig. 9 is a side view of the embodiment of FIG. 5. Instead of the thread 12, two pitch grooves 18 are provided at the rear end of the container 11, each of slightly less than 180 ° of the circumference, in which engage two inner journal stubs 19 of the connector 14. At one point on the circumference, the journal stubs 19 can be inserted into the pitch grooves 18 and brought to the fixed closed position by clockwise rotation. The rubber-elastic handle 20 is attached to an extension 21 of the connecting piece 14. A membrane 22, which is clamped between the flat surfaces of the adjusting sleeve 10 and inside the connecting piece 14, seals the air space in the handle 20 against the lower liquid supply. If you press the handle slightly together, as indicated by arrows, the membrane assumes the dash-dotted curvature, so that a greater pressure in the liquid space supports the escape of the liquid. In FIG. 10, the beginning of the introduction of one and the end of the other pitch groove 18 are shown enlarged, and, as indicated, a journal stub 19.

Fig. 11 shows a honeycomb, very supple design of the profile body 13, e.g. made of silicone.

12 is a side view of the dosing unit 9 pre-assembled from end cap 1, ball 2, cage 4 with flat spring 6 and an additional container 11a. This additional container 11a has a larger volume than the container 11 and enables the device to be stored upright (standing). The additional container 11a can be made of glass or plastic and opens at the top into a cylindrical neck 23, onto which the connecting piece 14 with its sleeve-shaped extension 24 is pressed. Before this, the adjusting sleeve 10, preferably provided on the outside with annular elevations (not shown) for sealing, has been fastened, which also has a sealing task with respect to the end cap 1. All assembly parts are rotationally symmetrical, which can be easily manufactured and fed. The pin stub 19 in the upper region of the connecting piece 14 can be pressed into two die halves 27 by two counteracting punches 26 before the insertion of the adjusting sleeve 10 in half the wall thickness of the connecting piece 14. After this process, the die halves 27 are moved to the center in order to be able to remove the pins 19 formed therefrom. This process is shown schematically in the side elevation of the additional container 11a. The metering unit 9 contains the two pitch grooves 18 on the outer diameter of the end cap 1.

Fig. 13 shows an enlarged front view of a fully assembled additional container 11a with a scale on the end cap 1 for the adjustable dosage amount. The two externally accessible slope grooves 18 of the end cap 1 are highlighted. Below this is the top view of the design of an end cap 1, in which there is a somewhat raised ring 28 around the application ball 2, so that between him and the ball, the emerging liquid can emerge over a small area, which is useful, for example, for applying liquids, including e.g. B. nail polish is advantageous.

Fig. 14 shows the top view of the surface of the end cap 1 with concentric mini-ribs, which additionally activate the sensory nerves when the liquid is applied.

Fig. 15 shows the neck area of a glass version of the container. The inner stepped diameter region 25 is provided for fastening the adjusting sleeve 10. If the achievable accuracy is sufficient when manufacturing the device in the blowing process, the two pitch grooves 18 could be provided in the outer diameter. The journal stubs 19 would then, as described in FIG. 12, be pressed from the outer wall of the end cap 1 into the interior.

16 shows an enlarged view of the assembled cage 4 in a symmetrical design with two anvil surfaces 8 and a closed spring ring 6, which greatly facilitates automatic parts feed. The spring ring 6 is also made of plastic and is therefore thicker. The resetting behavior is decisive for the selection of the material.

17 is a top view of the cage 4 with the closed spring ring 6 installed.

In Fig. 18, the transfer of the previously assembled cage 4 for inserting the cap 1 is shown in a schematic elevation. Two small parts turntables are provided for this. On the left plate, the ball 2 was previously filled into the end cap 1 using known feeder technology, the cage 4 with the two skid-like supports of the anvil web 8 was fed onto the right plate and a lockable spring ring 6 was placed on it. The cage 4 is then pushed from the turntable at the transfer station into a pair of tongs 29 above the end cap 1, then rotated and gripped by an insertion stamp 30 located above it and conveyed into the end cap 1. FIG. 19 is a top view of the schematic round plate cutouts in the area of the transfer station of the cage 4 into the end cap 1. It may be expedient to provide the metering unit in a subsequent (cycle station) assembly station of the left turntable with the connecting part 14 and into it bring fixed closed position. This would simplify and accelerate the completion of the container in the filling plant.

20 shows a particularly advantageous design of the end cap 1, additional container neck 11b and connecting piece 14 for receiving the dosing unit 9. It enables a compact design, which is particularly suitable as a one-way design because of the low expenditure. The pitch grooves 18 are arranged in the outer diameter of the connecting piece 14, which can also be connected in part to the adjusting sleeve 10. The sawtooth-like design of the lower extension 31 enables greater tolerance compensation of the additional container neck 11b and acts in the inner diameter after the connection piece 14 has been installed as a seat lock. As already described, the two journal ends 19 are pressed into the interior of the end cap 1. If there is no possibility of removing the dosing unit 9, it is expedient to move the insertion groove somewhat from the end position. In addition, it can be narrowed, so that the journal stub 19 can only be pushed through with force after the filling process.

20a shows the fully assembled disposable consumption container 11a with adjustable fine dosing.

21 shows the design of a vibration system. Between the end cap 1, which can be unscrewed from the pendulum rod 32, and a limiting sleeve 33, rotatable profile bodies 13 made of silicone or foam are mounted in a row. A handle 34 forms the rear end. The ability to be dismantled (exchangeable) enables renewal and retrofitting of the device with other suitable variants of the profile body.

22 shows the limiting sleeve 33 as a simultaneous connecting part of two different rod bodies 32, e.g. the front part with fixed and the rear part with rubber-elastic material behavior.

In Fig. 23 the inner structure of the end cap 1 is shown. It is fixed or adjustable according to FIG. 20 on the connecting piece 14. A ring 39 is provided in between. Outside the screw part 37 there is an inner cone 38 for receiving the pendulum rod 32. Because the skin-functional oils have a very economical effect, it is also possible to use a liquid that can only be filled into the end cap 1. The end cap 1 designed according to FIG. 20 (indicated by dash-dotted lines) will then engage with the journal stubs in gradient grooves of the connecting piece 14 and be removable from it for the filling process.

24 shows the fastening of the connecting piece 14 with the pendulum rod 32 designed as a thin-walled tube in double size. In the pendulum rod 32, the threaded insert 35 can be pressed in at the front, the sharp-edged piercing shoulder 36 of which cuts into the inner wall of the tube 32 after a slightly increasing diameter. When screwing in the thread 37 of the connecting piece 14, the inner cone 38 additionally secures the seat of the threaded insert 35 in the pendulum rod 32.

In FIG. 25, rib-like mini structures are shown parallel to the longitudinal axis on the surface of the end cap 1, as can also be advantageous in all examples centrally to the central axis. They act as an intensive zone because they do not run on the skin surface like the profile body during a swinging movement, but slide over it. Fig. 26 is the execution of the profile body 13 as a star and foam part. This makes it necessary to record it in a version like it

Fig. 27 shows. Two complementary socket parts 40 can be plugged together with a profile body 13 under clamping action. The distance between the two inner plane surfaces of the mounting parts 40 is narrower than the thickness of the profile body in the assembled state, so that after assembly the spherical outer shape of the profile body 13 shown in FIG. 28 results.

Figure 29 is an enlarged view of the fully assembled device in the downward position of the applicator head 101, which is arranged with its inner diameter longitudinally displaceable on the outer diameter of the connector 106 to the container (bottle) not shown. For its attachment by means of the container neck, screwed or pressed in a known manner, a cavity 107 is used which is delimited by a plane surface 108. In this a passage 109 is provided for the filling material, which is interrupted by a central web 110 with a cylindrical projection 111 for receiving the compression spring 112 (FIG. 29a). The lower end of the spring is received by a cylindrical sealing and application element 102, the sealing ring 104 of which is supported in a cone of the outlet opening 103 and thus seals it. A guide projection 118 below the sealing ring projects into the outlet opening 103. It can have capillary channels on its outer diameter (FIG. 29c). The spring travel is limited by the contact of an annular projection 114 on the application head 101, which is supported against the rear annular surface 113 of the connecting piece 106. The assembly of the application head 101 on the connecting piece 106 enables the insertion bevel on the projection 114, which elastically expand the diameter during the forced application and then allow it to spring back into the original state. The application head 101 contains in the front area an annular web 115 with preferably three bearing points 116 (side view 29b), in which transmission levers 117 with matching recesses are seated. These have point-like systems 119 for the ring plane surface 120 of the connecting piece 106 on the outer side and button-like projections 121 on the inner side which engage in an annular groove of the cylindrical sealing body 102. When the application head 101 is actuated, the bearing point 116 moves to the annular surface 120, so that the transmission levers 117 perform an additional movement in the inner area in the same direction and thereby lift the sealing body 102 from its sealing seat, so that liquid can escape. A desired transmission ratio can be defined by different lever lengths from the bearing point 116 to the outside and inside. In the rest position shown on the left, there is no pressure from the outer lever ends 119 on the ring flat surface 120. Only the upward movement of the application head 101 against the spring action results in a non-positive connection to the sealing body 102 against the compression spring 112 and a relative movement thereof with respect to the application head 101, as shown in FIG the right side of Fig. 29 is shown.

A similar, but less precisely controlled result is achieved with the embodiment also enlarged in FIG. 30, in which the levers are replaced by a plate-shaped leaf spring 105 with cutouts which result in 103 fingers (FIG. 30a approximately in natural size). The finger ends are supported, fixed by an annular shoulder projection 122, on the flat surface 120 of the connecting piece 106, while the central spring area acts on the rear flat surface of the sealing body 102. In the left half of the figure the rest position and in the right half the use position with a full actuation stroke is shown. When the applicator head 101 is moved back, there is an additional elastic straight bending of the spring fingers as a result of the geometric relationships of the ring web 115 and the ring shoulder 122 when they move relative to one another that the protruding application body 102 can be pushed back from the skin surface and liquid can escape.

FIG. 31 shows an enlarged alternative solution, in which the sealing element is provided with capillary channels at the front and is firmly connected to the application head 101. A tube 123 is fastened in the passage 109 (FIG. 29), which has a guide projection 124 at the front, which is slidably received in the inner diameter of the ring web 115. The application head 101 is thus pressed forward over the sealing element, with the limitation as in FIG. 29, and it can release liquid when moving back over the capillary channels.

32 shows an exploded view of the components of an embodiment in which the filling material to be applied is sealed by a clamping device which is released by moving the application head 101 backwards. The connecting piece 106 has a central passage 126 for the filling material and in the upper region a cylindrical cavity 127 for receiving the neck of the container. In the lower section, in addition to the passage 126, two opposite recesses 128 are provided for the pivotable mounting of the clamping levers 125 and, in front of it, an annular recess 129 for fastening the collar 130 of the tubular liquid supply 131. The clamping levers 125 have rear lugs 132 for receiving in the cutouts 128, which are chamfered inwards for the pivoting movement and are axially fixed by the collar 130. At the lower end, the clamping levers 125 have an inwardly directed clamping web 133 and, on the outside, a cam-like elevation 134, which serves to control the clamping process. This has a guide curve in the longitudinal direction of the lever 125 and transverse to it the circumferential radius in the sealing position. The clamping is accomplished with the control ring 135, which is received under the action of the spring 137 in a recess 136 of the application head 101 and is supported in the fixation 138 of the connecting piece 106. In the rest position the Travel is limited by the annular projection 114 of the application head 101, which is supported on the rear annular surface 113 of the connecting piece 106. For luxurious contents, a ring guide groove 139 can be provided around the outlet opening for storing balls 140, so that instead of sliding, there is a rolling skin contact with the application head.

33 shows the assembled part of the device according to FIG. 33, the left half in the rest position and the right half in the final stage of the backward movement of the application head 101.

In Fig. 34 are enlarged elevation sections and two partial side view sections of an embodiment with a clamping seal, which manages with only three components. In the connector 106, the neck of the container is pressed with its inside diameter onto the inside outside diameter of the cavity 127, while there is a gap between the outside diameter of the neck and the inside diameter in the cavity. Thus, changes in diameter due to the interference fit cannot affect the sliding fit of the application head 101 relative to the intermediate piece 106. The liquid supply 141, which has two opposing cams 142 with clamping curves in the longitudinal direction in the clamping zone, adjoins the lower flat surface of the intermediate piece 106. A combined spring and control ring 144 is supported with the upper spring edge on the lower flat surface of the connecting piece 106 and presses the clamping cams 142 into the clamping position by means of the control ring 144, two webs 147 acting against the flat surface of the application head 101. The height of the webs 147 corresponds to the space required by the clamping cams 142 in the use position when the application head 101 is moved back. The spring itself can be designed as a plate-like flat spring 145 or as a bellows spring 146. A bulge 148 is advantageously provided and this is surrounded by a bead ring 149, whereby the distribution of the liquid on the skin surface is facilitated. 35 shows the fully assembled device, on the left in the rest position (without web 147) and on the right in the use position. The pin stubs 150 can be forcibly inserted into longitudinal grooves 151 via a nose 152 which forms the stop downward. The locking for a secure closed position can be made possible by rotating the application head 101 into a side groove 151a, while a slope groove 151b in the other direction permits the controlled opening of the liquid supply 141.

Fig. 36 shows greatly enlarged, seen from below, the geometric conditions of the closing process of the liquid feed 41, which deforms the round cross section in the lower half into two straight, closely fitting contact surfaces. For injection molding reasons, 142 grooves 155 can be provided in the cams.

37 shows in the upper half how the web 147 aligned with the clamping plane supports the reshaping of the liquid supply 141 when the application head 101 is moved backwards, while this indicated closed position in the lower half gives space for the widening clamping bead.

38 and 39 show a variant of the device in the rest position or in the use position, in which the clamping can take place at the very front in the bulge 148 if the outlet opening is kept very small (approx. 1 mm). Here, the two opposite webs 147, which support the deformation of the opening for the liquid in the use position, can be arranged in the bulge 148. In addition, the wall located behind takes over the control function for the clamping cams, so that only a compression spring has to be provided between the lower flat surface of the connecting piece 106 and the inner flat surface of the application head 101. This version is suitable for the precise application of adhesives and stain removers. In the embodiment according to FIG. 40, the liquid supply is not regulated by pinching off (compare FIGS. 32 to 39) but by an elastic buffer 157 which acts on the inner flat surface 156 of the application head 101. The movement of the application head 101 can also take place via a thread 163 on the bottle neck. This embodiment is advantageous if minimal amounts of liquid are to be discharged intermittently for a desired permanent setting. A bottle made of soft plastic is used for this, which enables pressure impulses on the liquid by actuation in the transverse direction. At the other end, the intermediate piece 106 mounted on the bottle neck has the plane surface provided with openings 59, on which the buffer 157 is arranged. Because of the larger tolerances of the thread on the bottle neck, there is an axial play when the application head 101 is screwed on. Therefore, a braking zone 158 is provided in the area of the adjustment of the amount of liquid in the application head 101, so that resistance must be overcome when this area is reached and left. This enables a defined setting because the spring action of the buffer 157 is also directed against a thread flank. However, the gap distances between the buffer 157 and the flat surface 156 cannot be fine-tuned enough for this dispensing of the smallest amounts of liquid.

In Fig. 41 it can be seen how the tuning can be done more finely. A suitably designed pressure surface of the buffer 157, e.g. B. a contrasting slope, can lead to fine gap differences with larger axial movements.

42, greatly enlarged, a pin 160 is provided in the buffer 157, which completely closes off the discharge opening 103. This is particularly important for crusting substances. In addition, the application head 101 merges into a stepped application tip at the front, which permits targeted placement. In use, the gun 101 must be advanced a little longer than the length of the pen. The Limitation of the path could also be done without a thread by means of stop 161, so that a user-friendly fix focus standby design results.

Fig. 43 shows the exterior of such a conception for natural size super glue, with the settings a for "compression" = "rest position" and b for "pull apart" = "use position".

44 shows a container design in a soft plastic design for a dispensing device according to FIG. 40 that can be set as the minimum. A pluggable intermediate piece 106 is provided therein in order to be able to refill the bottle. Lateral pressure pulses in a grip zone marked with arrows support the dispensing of the liquid. A falcon-beam-like elastic zone 166 is used to adapt to the skin surface in the longitudinal direction and leads to transverse vibrations of the application head 1 during the sliding movement. The application head 101 has rib-like mini structures parallel to its longitudinal axis, which during the reciprocating movement of the application head 101 cause intensive activation of the nerve endings in the skin surface.

45, an adapter ring 164 is provided in the application head 101, in which the internal thread 163 also shown in FIG. 40 is attached. An O-ring 165 arranged on the flat surface of the application head 101 forms the edgeless outer transition to the container.
