Abstract

The present invention relates to a dispensing apparatus at a container ( 1 ) for a liquid or several liquids or at a conduit. The front wall ( 2 ) of the container or the like has a dispensing tube ( 3 ), which is provided with a seat-forming holding element ( 10 ) for a valve body ( 20 ). According to the invention the valve body is mounted concentrically in the tube opening ( 8 ), has a rod-like shape ( 21 ) and is with an outer end ( 22 ) guided by said holding element ( 10 ) and with an inner end ( 26 ) of a cup spring ( 28 ), which surrounds it and which at least in its rest or closing position is designed as a cone, which is open towards the first-mentioned end and which is supported by and is prestressed against the inner side of said front wall ( 2 ) or a corresponding wall in said dispensing tube or the like ( 3 ).

Description

A completely satisfactory, reliable and airtight closure after completion of discharge, regardless of the viscosity of the liquid in question. Preferably, there must be additional securing means, which guarantee and strengthen the closing position.

By means of the recovery, it must also be possible, if desired, to be able to abruptly and spill-free interrupt the discharge or empty a container as completely as possible. In the known dispensing devices, the dispensing often takes place in an uncontrollable manner, whereby, for example, so-called after-drip or after-discharge can occur.

This should be effectively prevented by the present invention.

Another disadvantage of the prior art is that the force required for the output is inadequate, so that for example relatively large forces may be used to bring about an excessively limited output, or so that with a relatively small power supply an excessive output is achieved. . In this respect, the task of the invention is to create conditions for adjustable control to achieve an even output of a desired amount with adequate forces and the desired speed. Means that you get control over the media consumption to a desired volume, which means that the desired amount is always obtained and thus no unnecessary energy is consumed. This is an important factor in the product life cycle.

The prior art designs for dispensers are often relatively complicated, expensive and time consuming to assemble. They are sensitive to disturbances and are usually not integrated with or adapted to the container. The functionality can be negatively affected during longer storage times or varying storage conditions.

Finally, the design and position of the dispensing devices are often such that the devices can be easily damaged and their function compromised.

The design has a number of environmental consequences, which are factors that must be taken into account and which in today's products are of crucial importance. 10 15 20 25 30 526 165 3 Through the described design, conditions have been created to manufacture the entire dispensing device in one and the same material and also adapted, coordinated to the material of the container.

The entire unit can thus be recycled, with minimal environmental impact.

In previously known constructions several materials have usually been used, which means that these devices cannot be reused in an appropriate manner.

From a societal point of view, it is therefore important that constructions that do not require virgin resources are used. The discharge device now described is such a construction.

Another important function that the new design has, compared to older solutions, is that the used, almost empty container / box does not lie down and leaks uncontrollably after it has been used.

In all these respects, the present invention will create significant improvements or eliminate any shortcomings and risks. In addition, the invention will advance the state of the art in this field in various further respects. Some of these are thus the preconditions for recycling or integration, ie the provision of containers with fully or at least partially integrated dispensing devices, which have hitherto often been manufactured by other manufacturers and / or by other manufacturing materials, eg metal, with consequent risks of malfunctions etc. .

These objects are realized according to the present invention in that a discharge device of the type stated in the introduction is substantially as described in the characterizing part of claim 1.

Further features and advantages of the present invention will become apparent from the following description taken in conjunction with the accompanying drawings, which show some preferred but non-limiting exemplary embodiments in a partially schematic manner. 10 15 20 25 526 165 4 In detail, in diametrically axial, partly for the sake of clarity, slightly schematic cross-sections: Fig. 1 shows a first embodiment of a discharge device according to the invention in rest or closing position with partial enlargements, Fig. 2 the device according to fi g. 1 in working or discharge mode, Fig. 3 views according to fi g. 1 of a second embodiment of a dispensing device according to the invention, Figs. 4 device according to fi g. 3 in working or discharge mode, Fig. 5 views according to fi g. 1 of a fourth embodiment of a dispensing device according to the invention, where the container for this in integrated form contains all the components essential for the dispensing, Fig. 6 the device according to fi g. Fig. 5 in working or discharge position, Fig. 7 one in a discharge device according to fi g. 1 - 7 constituent, enlarged outer casing area showing a sealing lip in this constituent in the unaffected state in a diarnetral axial cross-section and Figs. 8 a view similar to fi g. 2 of a further modified discharge device according to the invention, which is particularly suitable for installation in a pipeline and the like.

In the drawing figures, 1 denotes a e.g. rotationally symmetrical container with a front, outwardly suitably slightly convex support wall 2, which centrally and axially projecting has a preferably substantially cylindrical discharge socket 3 with an outer thread 4 for screwing on a lid 5 with a corresponding inner thread 34. possibly a part of the wall 2 may alternatively consist of a separate part (not shown), which can be inserted into a dedicated opening in said wall. This latter embodiment may be preferred, if it is desired to fill the container at the front and then to fit the dispensing device. In the former case, the container open from the rear or downwards is filled from the latter direction, after which a piston 6 is fitted from the same direction or the rear or lower container end 7 is welded on. output means are in integrated form according to fi g. 5 and 6.

The container suitably consists of plastic, in particular of polyethylene or polypropylene. However, metal, especially aluminum, is conceivable as an alternative.

In the opening 8 of the socket, at a certain distance from its orifice plane 9, for example 3 - 20 mm in a practical embodiment, a projecting, circumferential lip 10 constituting a holding member and valve seat is arranged. Lip 10 can be considered as a cone which cooperates with the body 21 of the valve body 20 and which thus provides a braking, limiting function in connection with the enclosed medium being pressed out of the container. The lip is suitably made together with the nozzle or the whole container, preferably by injection molding, and projects tapered obliquely forwards towards the center of the mouth plane at a main or average angle of 30 - 60 °, preferably about 45 °. In detail, the taper is suitably so, see also Fig. 7, that the shoulder 11 of the lip extends axially further in the direction towards the rear end 7 of the container in order to increase the support for the end region 12 of the lip i 'in the direction from said container end. Suitably the lower side 13 of the lip shoulder is substantially straight, comprises approximately half of this side of the lip and encloses an angle of e.g. about 20 ° with the otherwise suitably smooth cylindrical inner wall 14 of the lip, while the lip on the upper side 15 in addition to a slightly concave arch at the shoulder is substantially straight and encloses an angle of on average 40 - 80 °, preferably approximately 60 ° between it and the opposite socket wall. Adjacent to the side 13, the lip on the underside forms a shorter, preferably slightly concave side 16, which thus easily diverges relative to the upper side 15, and which via a more marked buckling point 17 merges into a substantially straight release side 18, which together with the upper side ultimately forms a sharp lip tip 19 with an angle of 10 - 40 °, preferably about 25 °. The release side 18 encloses an angle of 5 - 45 °, preferably about 25 ° with the socket shaft in its intended extension. The lip occupies approximately 15 - 70% of the opening's cross-sectional area of the opening 8, ie spans about 10 - 50% of the diameter 8 of the opening.

The lower or rear end 7 of the container can in some cases be welded together after filling the container in a filling station. In other cases this end can be left open and a piston 6 or a filling is inserted into it, which in both cases is conveniently made so that the container is turned upside down, whereby, however, the socket or the like. 3 must first be closed, in particular by being provided with a valve body 20 corresponding to automatic closing.

This valve body 20 has a rod-shaped or substantially cylindrical body 21, the front or outer end 22 of which is constituted by a forwardly or outwardly preferably softly rounded head 23 with a circumferential jaw edge 24 projecting over the body, which is located within an at least substantially radial plane relative to the body. Adjacent to the hook edge, the head forms a suitably axial or slightly conical, short mantle surface 25, which via a smaller radius of curvature changes into a softly rounded head surface.

Alternatively, the head may be shaped like a cone.

The rear or lower end 26 of the body 21 suitably terminates abruptly at 27 and here merges into a disc spring 28, which together with the rear body end suitably has the approximate shape of a truncated cone with a cone angle of 30 - 60 °, preferably about 45 ° , is open forwards, ie surrounds the rear frame end with a distance growing from the end surface 27. By disc spring is meant here any form of resilient or elastic members which are arranged around the body. It may thus very well be about, for example, blades, legs or even wires, which are delimited from each other by spaces. However, the disc spring 28 preferably extends in principle from the basic shapes of a disc and is evenly thick, but ends in front of an approximately radial front end surface 29, so that a slightly oblique outward and forwardly directed tip is formed with an angle of about 30 °. This tip is slightly rounded, ie with a radius of curvature of 0.2 - 1 mm. The transition between the end surface 29 and the inner or front surface 30 of the disc spring is formed by a circumferential edge with a small radius of curvature, since said surfaces enclose an angle of 130 - 170 °, preferably about 150 °, with each other. Furthermore, the disc spring is equipped with a number evenly distributed along its circumference, transversely, possibly coaxially with the body through holes 31 of relatively large diameter, for example 15 - 40% of the extent of the spring from the body. Instead of holes, there may be arbitrarily designed, eg slit-shaped, possibly at the disc periphery freely opening, radially oriented openings.

The diameter of the frame is, for example, 10 - 50% smaller than the width of the socket opening 8. In this way, a discharge channel with a sufficiently large cross-sectional area is formed. The front end 22 and rear end 26 of the body preferably have the same diameter, whereby a shorter or longer concentric diameter reduction 32 may extend between the two ends.

This facilitates production and leads to material savings. In some cases (see, for example, fi g. 5 and 6), the hook edge 24 may extend inside the diameter reduction 32 and together with it form a keyway 33, in which the lip tip 19 can approximately conformally penetrate and thus account for a particularly effective holding action resp. seal. Alternatively, the diameter reduction 32 may penetrate the hook edge 24 and slightly into the end 22 or there may be intermediate solutions, ie both parts 24 and 32 are slightly angled inwards.

The design according to fi g. 1 and 2 work as follows. I fi g. 1, the container 1 is filled with a liquid and the lid 5 is screwed all the way down on the socket 3. In this case the lid rests, possibly with an internal elevation 36, against the head 23 and possibly this presses a little firmer down towards the hook edge 24 and a possible wedge groove on the lip tip. 19 (see fi g. 7), in which the latter in particular, in addition to the lip as a whole, is slightly expanded and / or caused to penetrate somewhat into the material of the rod-shaped body 21 in order to increase the sealing pressure and make cohesion more efficient. With or without a lid, however, the valve member 20 is slightly biased between the lip 10 and the wall 2, i.e. the lip tends to push the valve body outwards, while the disc spring 28 tends to pull the valve body further into the container. The total prestressing distance can amount to 1 - 10 mm, preferably about 2 mm in a practical embodiment, the described interaction between lid and valve means with some depression of the latter pre-bearing the prestress 10 slightly in favor of the area around the lip. , however, preferably without the tension in the abutment of the disc spring against the front wall ceasing completely. However, the disc spring is slightly relieved and its front, outer tip rests easily against the front wall.

If the lid is now removed or replaced with a spout 35 according to, for example, Fig. 4, the bias is almost equalized, if the pressing action has been exerted on the valve member, whereby the holding and sealing effect of the lip decreases somewhat. If you now wish to discharge some of the container contents, you squeeze an elastic container wall to increase the pressure on the contents of the container or activate, for example, a piston 6, whereby also the pressure is increased on the disc spring from inside the container and the spring is pressed under a slight flattening tendency towards the front valve body end lifts from the lip 10 and allows the lip to be elastically displaced substantially radially outwardly to form an annular gap 37 between the lip and the rod-shaped body 21, with liquid propagating or penetrating the openings 31, into the nozzle opening and said annular gap and out of the nozzle e dyl. and towards the application zone (see Fig. 2). During the discharge, both the plate spring, the openings therein and the lip held elastically outside said annular gap ensure that a certain far-reaching constant discharge pressure prevails, which has the consequence that the discharge becomes very even. The lip has an important role here as a form of a valve cone enclosing around the rod-shaped body 21, in order thereby to control the output fate. The gap between the lip 10 and the body 20 can be selected depending on the intended medium to be regulated.

When the discharge pressure is too low, the valve body 20 or the lip 10 closes, respectively. By correspondingly dimensioning and mutually size-related these parts, you have far-reaching control options. If you wish to end the exhalation, you only remove the pressurization of the container contents, whereby the disc spring, through its inherent resilience, springs back to it in fi g. l showed the closing position. In this resilience, the volume enclosed by the disc spring, the front wall and the socket is increased and a slight vacuum is created, which is lifted partly by sucking liquid into said volume from the interior of the container through the openings in the disc spring and partly by liquid is sucked in from the outermost free end of the nozzle outside the valve body head 23 and the lip 10 and through the annular gap 37, which accelerates the valve closure, in particular as said vacuum arises also on the entire underside of the lip including the release side. The magnitude of this vacuum level can be varied by changing the magnitude of the spring force, and thus adapted to conditions suitable for the different applications. However, the vacuum is so small that no air is sucked into the container from the outside, since only a fraction of the liquid-filled or liquid-covered space outside the lip is affected. When the valve has closed, a balance of pressure enters through the openings in the disc spring and only the remaining tension of the latter, ie elastic abutment pressure against the inside of the front wall, keeps the valve closed.

During the described tensioning movement of the valve plate, the free surface 29 slides along the inside of the front wall, the transition between the inside 30 and the surface 29 closest to the sliding contact (fi g. 2), then the entire surface 29 and finally (fi g. 1) the radially outermost pointed part. At the transition from closing to discharge, the process is reversed. This means that the tip of the plate and the inside of the front wall are spared and these parts can reach a significant service life without fatigue or malfunctions.

After dispensing, a lid 5 is suitably screwed back onto the nozzle with previously described consequences. If the container contents are, for example, an adhesive, you can possibly wait a bit until the rest of the liner in the outermost socket part has solidified and can be lifted off. If a spout is used, this can possibly be thrown away together with glue residues solidified in this and the socket opening, when a new discharge takes place using a new spout at a later time.

In the embodiment according to fi g. 3 and 4, openings 31 are missing in the disc spring and instead the rod-shaped body 21 is hollow. The rearwardly open cavity 38 extends all the way to the front rod end 22, where the large cavity 38 terminates abruptly, but communicates with the area outside this rod region via transversely through the body, discharge holes 39 distributed along the periphery, which suitably have a lying rectangular profile, and which are covered by the lip 10 in the closed position. Since the release side 18 of the lip from the tip 19 can slope slightly downwards and outwards, it can be advantageous if a pointed bead 40 going around the outside of the body is arranged below the discharge holes 39. As can be seen from fi g. 3, the bead 40 penetrates slightly into the lip in the closed position and prevents liquid from penetrating into the hollow space 41 between the body 21, disc spring, front wall, socket and lip, which in some cases may be important, e.g. must be filled with air or another liquid.

The bead can also serve to in the open position in fi g. 4 keep the lip tip slightly spaced from the body to guide the lip tip past the discharge holes on the way to the closing position and only after passing these holes allow the lip tip to lie against the holes, the main walls of which could otherwise damage the lip tip.

This embodiment otherwise functions as first described, only that the container contents do not penetrate across the disc spring, but pass through the rod-shaped body and upon reaching a certain level of pressurization through the discharge holes, when the valve member has lifted slightly away from the lip and the discharge holes are exposed. After the said pressurization level has fallen below, the disc spring pulls the valve body back downwards to the closing position according to Fig. 3.

I fi g. 5 and 6 show an embodiment of the container, which in principle is similar to the embodiment according to fi g. 1 and 2. What is there from the front wall 2, however, is here arranged in the form of a ledge inside the socket 3, which in preferably elongate shape is made in one piece with the container. The rear container end 7 is open up to the filling, wherever it is closed, preferably by welding together (see fi g.6).

That i fi g. 8 is particularly suitable for installation in a pipeline 44 or in a container nozzle. The embodiment comprises an external, eg circular-cylindrical plug 10, 526 526 165 11 45, the front / outer end of which is an orifice plane 9, and the rear / inner end of which has the function of said support wall 2. Internally, the plug is designed as the design according to fi g. l and 2, alternatively fi g. 3 and 4. The valve member is also designed according to these figures or according to some of the other figures. The advantage of this embodiment is that it can be applied to conventional container nozzle and pipeline designs, where fastening takes place in a known manner. When arranged in a pipeline, where the force or bias of the disc spring is preferably considerably greater than that which applies to container routing, an instrument is thus obtained by selecting said force / bias to allow automatic discharge above a corresponding pressure level and also automatic, spill-free closing in the event of undercutting. of said level. The flow is also even.

The invention is not limited to the embodiments described above and shown in the accompanying drawings, which can be modified and supplemented in any manner within the scope of the invention concept and the following claims. Thus, details can be exchanged between the different designs.
