Definitions
- the invention relates to a spray attachment for the radial discharge of liquid substances according to the preamble of patent claim 1.
- liquid substances are liquids whose viscosity is low enough to ensure undisturbed continuous flow.
- Sprühein directions for liquids and creams are known, which are applied with a spray pump via a spray valve.
- a diversified spreading of liquid substances is possible only to a limited extent with such spray valves.
- the spray valves over time tend to clog, whereby the Auffä chern the spray can be further affected.
- a disadvantage of the known spray systems is their complex and expensive Konstrukti on.
- the sieve-like passage openings of the attachment parts are often quite different in terms of their diameters and therefore often do not permit a uniform spray jet during use.
- the fanning of the spray is often uneven.
- Object of the present invention is therefore to provide a spray attachment, wel che is suitable for use in conjunction with liquid substances.
- the liquid substance should be able to be radiated out of a container through the spray attachment by squeezing the container wall.
- the invention proposes a spray attachment for the radial discharge of liquid substances.
- the spray attachment comprises a cap with a ring-shaped circumferential, closed shell with a wall, on the inside or outside of first fastening means are formed.
- the first fastening means are designed to engage in corresponding second fastening means, which may be provided on an outer wall or inner wall of a container neck.
- At one longitudinal end of the jacket is closed by a top surface having a recess.
- a receiving part for receiving an insert part is arranged.
- the receiving part has a closed in the circumferential direction conical receiving surface.
- On the insert part a substantially correspondingly conical peripheral surface is formed.
- the insert part has an axial extension which is equal to or smaller than an axial extent of the receiving part.
- the conical receiving surface of the receiving part and the conical peripheral surface of the insert defining at least one passageway for the liquid substance, through which the liquid substance can be discharged, when the conical receiving surface and the conical peripheral surface abut each other.
- the at least one passageway is delimited by the cooperating conical surfaces of the receiving part and the insert part, there are much greater freedom for their training and production just as in the siebarti gene inserts of the prior art. This is similar to the conical surfaces formed by the receiving part and the insert part fürtittskanal a tube having an inlet opening and an outlet opening.
- the at least one passage channel can also be produced in the mass production process with significantly greater uniformity, which has an advantageous effect on the unit cost.
- the insert is both spatially and temporally separated ge of the remaining closure produced, so that these two parts must be mounted after completion of injection molding into each other, as well as in a 2K injection molding, in which already the complete spray attachment is prepared in a procedural step.
- the inventive design also makes it possible to produce the at least one passage channel with smaller diameters, without having to resort to costly manufacturing processes, such as laser drilling.
- the receiving part may for example be equipped with projections which engage in the Mon day of the insert part behind this and prevent falling out of the insert form-fitting manner.
- the insert part which may be manufactured as a single part, after being mounted in the receiving part, which is generally formed integrally on the top surface of the shell, be movable or fixed in the axial direction.
- Movable in the axial direction means that the insert member relative to the receiving part from a first position in which the conical receiving surface of the receiving part and the conical peripheral surface of the insert abut each other, in a second position on which the conical receiving surface of the receiving part and the conical periphery surface of the insert part are spaced apart, is displaced, and vice versa.
- a portion of the at least one passageway in the form of a groove on the conical receiving surface of the receiving part and / or the conical peripheral surface of the insert part may be formed. As a rule, this portion will be U-shaped or V-shaped.
- the at least one passage can therefore be formed by the conical receiving surface of the receiving part and the conical peripheral surface of the insert abut each other.
- the passageway can be formed by the groove on the conical receiving surface, respectie ve on the conical peripheral surface, by a flat portion of the conical peripheral surface, respectively the conical receiving surface, is covered or by the groove on the conical receiving surface and the groove At the conical peripheral surface overlap each other, It can be formed passageways, which have a cross section to down to about 0.005 mm 2 , and thus form a very fine beam. Such fine openings can not be achieved by spraying, rather such small cross-sections would have to be drilled, for example by means of a laser.
- the cone of koni's peripheral surface of the insert part can be aligned in the assembled state so that its base faces the free end of the shell, respectively, when mounted on a container spray attachment to the stored in the container contents.
- the insert part can be displaced from the second position to the first position by squeezing the container, so that the conical receiving surface of the receiving part and the conical peripheral surface of the insert abut each other and thereby the at least one Passage channel is formed.
- the squeezing can cause an elastic rever sible deformation of the container wall of the container, which is multiple executable bar without damaging the container.
- the pressure in the container can rise and the stored contents press on the base of the conical peripheral surface of the insert and relocate the insert to the first position before the stored liquid substance at least in part through the at least one container Passage passage formed ver leaves. Due to the configuration as a conical receiving surface of the receiving part and conical peripheral surface of the insert part, an increase in the pressure in the container interior also leads to an increase in the contact pressure of the conical receiving surface to the conical peripheral surface or vice versa.
- angles which include the conical receiving surface with the central axis of the receiving part and the conical peripheral surface with the central axis of the insert part are the same, so that a flächi ges juxtaposition of the conical receiving surface and the conical peripheral surface and not just a linear contact , In most cases, the two angles are formed such that the conical peripheral surface and the conical receiving surface do not abut each other in a self-locking manner. If sufficient liquid substance is dispensed from the container by squeezing the container, the dispensing of the liquid substance can be interrupted by reducing the pressure on the container down to zero. In addition, by a restoring force of the container this under
- the insert part By generating the negative pressure, the insert part can be moved from the first position into the second position. be stored, so that the cross section through which the ambient air can get into the container interior, compared to the cross section of the passage channel can be increased. This allows the container in a shorter period of time to return to its original shape before crushing as if the ambient air alone through the cross-section of the passage channel would have to get into the container interior.
- more than one passage channel are formed in a spray head. Basically, the liquid substance from the spray attachment by appropriate alignment of the conical on receiving surface of the receiving part and the conical peripheral surface of the insert part as convergent by appropriate formation of the grooves are brought in parallel and divergent. In the presence of more than one passageway, in a convergent deployment, the beams may meet at substantially one point or intersect without contact.
- the at least one passage channel is formed by a groove which is formed on the conical receiving surface of the receiving part and / or on the conical peripheral surface of the insert part. From this they produce the following three variants for the formation of the passageways:

- the grooves in the (inner) circumferential surface 65 of the insert part according to FIG. 16 have a divergent profile in the direction of spraying. This will remove the spray the liquid substance already on leaving the spray attachment 1 from the central axis of the insert part. A mutual contact of the individual rays is excluded.
- the spray attachment according to the invention is designed for the spraying of liquid substances.
- liquid substances according to the present invention are meant liquids whose viscosity is low enough to ensure undisturbed continuous flow.
- the spray attachment is preferably produced in a plastic injection molding process and / or a plastic molding process. As plastics all suitable for injection molding and / or plastic molding plastics can be used.
- the cap with coat including top surface and receiving part in one piece from a plastic from the group starting from polyolefins, in particular polyethylene and polypropylene, HDPE, LDPE, de Ren co-polymers, recycled from said polyolefins and mixtures of said polyolefins and from polyesters, in particular PET, PEF, PPF, PBT, their co-polymers, recyclates of said polyesters and mixtures of said polyesters.
- the cited plastics are sufficiently tested for the injection molding process and / or plastic molding process and their chemical and physi cal parameters known.
- the casing together with the top surface and receiving part and the insert part consist of the same plastic.
- This embodiment variant of the spray attachment has the advantage of a particularly good dimensional stability, since the cap, in particular the receiving part, and the insert part have the same shrinkage.
- a plastic container with an inventive spray attachment 1 has a container body, which is at least partially elastically reversible fauxquetschbar. Spraying the flüssi gene substance is done by squeezing the container body by hand.
- the displaceable insert 6 is displaced from a second, open position to the first, closed position by the pressure which is increased in relation to the atmosphere within the container body, so that the conical peripheral surface 65 of the insert part 6 and the conical receiving surface 55 of the receiving part 5 abut each other.
- the liquid substance is discharged through the surfaces formed by the superimposition of the conical surfaces 55, 65 through channels 7 from the container body.
- the tendency of the container body to return to its original shape due to its rigidity forms a suppression in the container body with respect to the atmosphere surrounding the container.
- air can enter through the passage channels 7 into the interior of the container, as a result of which the container body expands again and assumes its original initial shape.
- a displaceable insert part 6 can be withdrawn from the first position to the second position by the existing in the container body oppression, so that forms an annular gap between the conical surfaces 55, 65 of the receiving part 5 and a set part 6, through the air can reach the container body and thus the provision of the container body is faster executable.
- the displacement of the insert part from the first position to the second position can also be spring-assisted.
- the plastic container can ren in a Blasverfah, for example, in an extrusion blown or in a Streckblasverfah, be prepared.
