Description

The invention relates to a metering container for solder with a filling opening having, cup-shaped container wall, with a central axis, with a filling opening limiting container edge, with a sealing surface on the container edge for applying a lid seal and with a removable lid, wherein the lid Compressed air nozzle for introducing compressed air, wherein the lid by means of at least one holding means indirectly via the lid seal against the sealing surface in the axial direction a for closing the filling can be applied.

There is already known a metering for solder such as brazing or high temperature solder. The containers have a cup-shaped container wall with a bottom-side outlet and a removable lid. Inside the lid, a compressed air nozzle is provided for introducing compressed air. The lid has a holding and sealing edge and is coupled via a retaining ring with a flange of the container, wherein between two flat edges formed an O-ring is inserted as a seal.

Out JP2003-181634 A is a metering container for solder with a cup-shaped container wall and a lid disposed thereon known. To attach or seal the lid, the metering container has a plurality of circumferentially spaced retaining clips, which are biased for the purpose of biasing the lid in the axial direction via a rocker arm.

The invention has for its object to form a dosing and arrange in such a way that a simplified closure is guaranteed.

The object is achieved according to the invention in that at least three distributed over a circumference U holding means are provided in the region of the filling over which the lid is positively prestressed in the axial direction a, wherein at least two holding means in a position P1, in which the holding means not is biased against the lid in the axial direction a, in the radial direction r in positive engagement F1 can be brought to the lid and / or the lid has a stop means, such that the lid on the stop means in a position P1 of the holding means in which the holding means is not biased against the lid in the axial direction a, in the radial direction r with the container edge in positive engagement F2 can be brought and / or the lid has a recess in which the lid seal is arranged such that the lid seal when placing the Cover on the container edge against the sealing surface on the container edge can be applied and that the D eckel has a stop surface with which the lid against the container edge can be applied, wherein the biasing in the axial direction of a at least two holding means against the lid first the lid seal against the sealing surface is biased and only by further axial biasing of the holding means against the Cover the holding means in a position P2 can be brought, in which the stop surface against the container edge can be applied.

This ensures that the lid after placing on the container edge has a necessary for subsequent sealing and subsequent closure relative position to the container or the container edge. Furthermore, it is achieved that the holding means in positive engagement with the lid edge is such that it inevitably has the predetermined relative position to the lid edge, thus the necessary positive connection with the lid edge upon further setting or preloading. In addition, it is achieved that the cover seal after setting the holding means or the lid has a predetermined bias, so that on the one hand the desired sealing force of the lid seal or desired contact force is ensured against the sealing surface and on the other hand, excessive bias or Loading the lid seal is prevented.

The positive connection F1 between the holding part and the lid edge is ensured by a retaining lug which can be brought into a corresponding recess of the lid edge in a form-fitting manner. The stop means, which establishes the radial form-fit F2 between the lid and container rim, guaranteed in the context of the provided radial clearance in any case a sufficiently accurate positioning of the lid on the container edge in a relative position in which the lid seal properly on the sealing edge rests. This already without application or pre-adjustment of the holding means. The lid can be positioned by simply placing it, whereby the user is ensured a check of the correct position due to the given stop means.

Dosing container in the aforementioned type are already known from the house Walther spray and Lackiersysteme GmbH according to excerpt from the brochure "Walther Pilot, A round thing (2 pages)" and "Walther Pilot, agitators in their diversity, p. 12 and 14" ,

The metering containers known here also have different holding means distributed over the circumference, which fix the lid on the container. However, the handling of these covers, especially the placement and proper closing or biasing disadvantages.

It may be advantageous for this purpose, if the lid seal is designed as an O-ring or as Axialdichtring. The training as an O-ring is a very robust, above all favorable solution, since O-rings in various sizes and materials are very readily available on the market. By using an axial sealing ring, the contact pressure required for the tightness of the cover seal can be significantly reduced, which improves the handling when closing.

Further, it may be advantageous if the holding means is formed from a retaining bolt which is pivotally mounted on the container wall, and a holding member axially displaceable on the retaining member, wherein the holding member by axial displacement on the retaining bolt in positive connection F1, F2 brought to the lid is. Through the use of a pivotable bolt in conjunction with a sliding on the bolt holding part, the latter can bring in a very simple and fast way in a positive locking F1, F2 ensuring relative position to the lid or lid edge. The same applies to the release of the lid to open the dosing.

It may also be advantageous if the holding part has a retaining lug and the lid has a lid edge with a peripheral recess, wherein the retaining lug and the recess can be brought into axial contact with the retaining pin in positive locking F1, F2. By forming the recess in a circumferential shape, ie over the entire circumference U, the cover can be placed arbitrarily on the container with respect to the circumferential direction, so that in each of these arbitrary positions, the holding part with its retaining lug in said recess can be used.

It can be advantageously provided that the cover has a guide element for a guide member of a feasible in the dosing tank piston. The guide element ensures a guide of an insertable piston, so that it is not tilted or jammed during the dosing process, thus during axial displacement within the dosing. The guide member of the piston is mounted within the guide member in the radial direction, the requirements for the radial clearance are not very large. A clearance is completely sufficient.

The object is also achieved by a system consisting of a dosing according to one of the preceding claims with a guide rod having piston which can be applied within the dosing against the container wall in the radial direction r over the circumference U, wherein the piston for the purpose of promoting solder in the outlet is displaceable in the axial direction a. The aforementioned system ensures a very fast and above all overall certain, therefore safe use, especially when closing dosing, which prevents operator error especially in the daily sequence.

Further advantages and details of the invention are explained in the patent claims and in the description and illustrated in the figures. Show it:

1 shows a dosing 1 consisting of a cylindrical container wall 2 with a filling opening 2.1 , a floor area 2.4 as well as one within the floor area 2.4 arranged outlet 1.1 with an adjoining outlet flange 1.2 , Furthermore, the metering container 1 a lid 5 as well as four holding means 6 to 6 ''' on top of that the lid 5 on a container edge 3 of the container 1 is fixed. The dosing tank 1 or the container wall 2 has a central axis 2.2 on, with the lid 5 over the holding means 6 to 6 ''' in the axial direction a to the central axis 2.2 against the container edge 3 can be applied or prestressed.

After the 2a to 2c is a preferred embodiment of the holding means 6 shown in different positions P1, P2.

The container wall 2 is up through a container edge 3 , the filling opening 2.1 forms, limited. Immediately below the edge of the container 3 is a warehouse 2.3 for the holding means or a retaining bolt 6.3 provided, the pivoting in stock 2.3 is arranged. On the retaining bolt 6.3 There are an axially to the retaining bolt feasible holding part 6.1 and then a holding nut 6.2 , The holding part 6.1 has a retaining nose 6.1a on, which is formed by a corresponding recess on the far cylindrical holding part. The lid 5 has a lid edge 5.6 on, on which one with the holding part 6.1 corresponding, circumferential recess 5.7 is provided. On the container edge 3 facing side of the lid edge 5.6 is a circumferential recess 5.3 provided within which a lid seal 4 is placed. Furthermore, the lid edge 5.6 on this page a stop surface 5.4 on, within the aforementioned recess for the lid seal 4 is arranged. The lid seal 4 is in the axial direction a over the stop surface 5.4 above.

To 2a is the lid 5 over the lid seal 4 on the edge 3 or a sealing surface 3.1 of the edge 3 placed in the axial direction a. The stop surface 5.4 according to 3 a predetermined gap d to the sealing surface 3.1 on which by the supernatant of the lid seal 4 is determined. The holding part 6.1 is with the holding nose 6.1a into the recess 5.7 the lid edge 5.6 used or applied in the axial direction a and in the radial direction r. By appropriate positioning of the retaining nut 6.2 becomes a position P1 of the holding means 6 achieved in total, in which a bias of the lid 5 or lid edge 5.6 against the container edge 3 not yet done, being between the holding part 6.1 or the retaining lug 6.1a and the lid edge 5.6 a positive fit F1 acting in the radial direction r is formed. Thus, the holding means 6 in general or the holding part 6.1 in particular no longer in the radial direction r to the outside from the here shown, the positive connection F1 in the axial direction a to the lid edge 5.6 forming position P1 are pivoted.

To 2 B points the lid edge 5.6 a lifting gear 5.2 on which, in the resting position of the lid 5 in which the lid seal 4 over the holding means 6 is not biased, acting in the radial direction r positive fit F2 with the lid edge 3 forms. The lid 5 thus indicates in the 2a and 2 B on the lid edge 3 seated position a acting in the radial direction r game s, however, by said stop means 5.2 so limited is that the lid seal 4 in any case, properly on the sealing surface 3.1 seated. In the axial direction a, the lid can 5 in the position P1 of the holding means 6 while still being raised or moved. However, as already stated, a notching or slipping out of the holding means 6 or the holding part 6.1 from the recess 5.7 due to the on the retaining bolt 6.3 sitting mother 6.2 not possible anymore. Thus it follows from the position 2a respectively. 2 B by further biasing the holding part 6.1 about the holding nut 6.2 inevitably to a bias and fixing the lid 5 on the container edge 3 to 2c ,

According to 2c is now the holding part 6.1 about the holding nut 6.2 and the retaining bolt 6.3 against the lid edge 5.6 biased such that the stop surface 5.4 the lid edge 5.6 against the container edge 3 or the sealing surface 3.1 is applied. Starting from this fixed position P2 of the holding means 6 is another biasing or deformation of the lid seal 4 due to said system between the stop surface 5.4 and the container rim 3 not possible anymore. The preload and the sealing effect of the lid seal 4 are therefore defined.

To 3a the sealing and investment conditions are again outlined in an enlarged view. The container edge 3 has the sealing surface 3.1 on top of that the lid gasket 4 rests. The lid seal 4 is inside the recess 5.3 the lid edge 5.6 placed and is in the axial direction a over the gap d on the stop surface 5.4 out. The slings 5.2 the lid edge 5.6 has a game running in the radial direction r s to the container edge 3 on.

After embodiment 3b this is the lid seal 4 around an axial shaft sealing ring, which is against the sealing surface 3.1 over a sealing lip 4.1 is applied. The present gap d is slightly lower against the background of training as Axialwellendichtring, because it due to the operation of the lid seal 4 requires a much smaller axial preload.
