Description

  The present invention relates to a foil pack tie for storing and loading in a receiving part of a discharge device, and in this foil pack tie, the components of a multi-component substance are stored separately from each other and juxtaposed with each other. A mounting side provided with two foil packs, a first receiving part for the end of the first foil pack, and a second receiving part for the end of the second foil pack, and a mounting side of the base plate A head portion having a base plate having a side surface projecting with a mixing connection portion on the opposite side, and a first outlet having a first outlet for one component of a multi-component substance at the free end of the mixing connection portion. A second outflow path having a second outlet for the at least one other component in the multi-component substance at the free end thereof, and connecting the first receiving portion to the first outflow path; First communication passage for, and a foil pack tie the second receiving portion provided with the second communication path for connecting the second outlet channel to the base plate.

  For example, multi-component materials such as mortars, foaming agents, and sealing agents can be used by the user as two-component or multi-component materials stored in cartridges and foil pack ties. Foil pack ties are known to be useful as packages for such substances and, in particular, require less material than cartridges and should be disposed of after the substance has been dispensed. It is excellent in that the amount is small. Furthermore, the foil pack tying tool can be easily and inexpensively manufactured.

  The foil pack tying member is loaded or inserted into a receiving part of a discharge device such as a dispenser. By the discharge mechanism, each component is simultaneously pushed out from the head part through the outflow path in the mixing connection part, and when guided through the mixing housing having the mixing element, it is agitated in the mixing element to form a desired mixture, and the application site Discharged.

  The foil pack tie described in Patent Document 1 (German Utility Model No. 9100054) has two foil packs juxtaposed with each other, and the mixing connection portion in the head portion is provided with a partition wall, Two outflow paths juxtaposed to each other are realized for feeding each component of the two-component substance to the mixing element. The feeding performed in the mixing connection portion is also juxtaposed (side by side) feeding.

  A drawback of this known prior art is that when discharging the foil pack tie, there is a partition in the mixing connection and each component flows along the inner wall of the mixing connection next to each other in parallel. is there. For this reason, in order to sufficiently stir each component, a high mixing energy or a sufficiently long path by a mixing element is required. As a result, a high squeezing force is required to discharge the multi-component substance.

  Patent Document 2 (German Patent Publication No. 4138351) describes a mixing housing that can be fixed to a head portion and that includes a mixing element. This mixing housing is provided in front of the mixing element and comprises a receiving part for the premixer formed as an independent element. This premixer transforms the flow of components delivered from the mixing connection by juxtaposition (side by side) feeding into a divided laminar flow, and this laminar flow is fed to the mixing element in the mixing housing. As a result, each component is more suitably agitated in the mixing element, and the mixing path required for it is shortened, and the force required to squeeze out the substance attached to the foil pack tie is also small. I'm sorry.

  The disadvantages of this known prior art are that the premixer is an independent element, e.g. the premixer is accidentally lost, or because the premixer is received in the mixing housing. Therefore, it cannot be used for a commercially available mixing housing.

German utility model No. 9100054 specification German Patent Publication No. 4138351

  Accordingly, an object of the present invention is a foil pack tie comprising two foil packs and a head part juxtaposed to each other, which is always mixed uniformly from various mixing elements and with low squeezing force throughout the discharge operation. And to obtain a foil pack tying tool in which the head portion can be easily manufactured.

  This problem is solved by the features described in the independent claims. Preferred embodiments of the present invention are described in the dependent claims.

  According to the present invention, the first outflow path is divided into two divided paths separated from each other at least in the free end region of the mixing connection portion, and the second outflow path is disposed between the two divided paths.

  Both dividing paths are separated by the second outflow path so that they are completely separated from each other at least in the free end region of the mixing connection. When the entire component stream is discharged from the foil pack tie, it is dispensed directly in the head portion. This head portion is preferably integrally constructed. At this time, the flow of at least one component is surrounded or collides with at least two directions of the flow of other components to be distributed. A conventional mixing housing is attached to the mixing connection. This ensures that the mixing element mounted in the mixing housing, based on each distributed or pre-distributed component, ensures uniform agitation and is basically shorter than conventional foil pack ties. .

  Furthermore, the foil pack used in the foil pack tying tool of the present invention should be arranged at a distance from the conventional foil pack tying tool without causing an undercut that makes it particularly difficult to manufacture an integral head part. Can do. Since the separation distance can be set in various ways, the range of the component ratio that can be implemented in the foil pack tying device according to the present invention can be greatly increased. This was conventionally possible only with a multi-part head portion or only with a hard cartridge. According to the present invention, for example, a foil pack tie having a component ratio of 11: 1 to 10: 1 or a foil pack tie having a larger ratio than this can be realized. In particular, a foil pack binding tool having a component ratio of 5: 1 can be easily realized.

  Preferably, the mixing connection has a circular outlet shape, and the second outlet channel completely divides the circular shape and is adjacent to the second outlet channel itself, and is separated from each other by at least two second outlet channels. An arcuate segment of a circle constituting a dividing path of one outflow path is formed.

  Preferably, the head portion is formed by injection molding of a synthetic resin. More preferably, the head portion is integrally formed. By disposing the second outflow passage in the first outflow passage, the mold can be easily released. In addition to being easy to release, the simple geometry of the head part (preferably integral) also improves the sealing between the mixing connection and the head part.

  Preferably, the partition wall separating the dividing path and the second outflow path is formed integrally with the mixing connection portion. With this configuration, the number of elements to be manufactured and handled in the foil pack tie can be reduced. Preferably, the entire head portion is integrally formed and the foil packs are each affixed to a corresponding receiving portion. By doing so, the foil pack tying tool can be manufactured easily and economically.

  Preferably, the cross-sectional areas of both dividing paths are equal in a plane extending parallel to the plane in which the base plate exists. With this configuration, it is possible to divide the component flow symmetrically from the first mixing stage, and to optimally use the space of the mixing element (preferably static). In a mixing connection with a circular outlet, the second outlet channel preferably extends along the center of the circular outlet, and the resulting mirror symmetry allows any cut through the center or the center of the circle. In terms, the flow of all components is always divided in the same way.

  Preferably, for each plane extending parallel to the plane in which the base plate lies, the ratio of the total cross-sectional area in both dividers to the cross-sectional area in the second outlet channel is the ratio of the cross-sectional area in the first foil pack. , Corresponding to the ratio to the cross-sectional area in the second foil pack. With this configuration, suitable agitation is achieved.

  Embodiments of the present invention will be described in detail below with reference to the drawings.

It is a fragmentary longitudinal cross-sectional view in one Embodiment of this invention foil pack binding tool. It is the cross-sectional view seen from the II-II line | wire of the head part of the foil pack binding tool shown in FIG. FIG. 3 is a cross-sectional view of the head portion of the foil pack binding tool shown in FIG. 1 as viewed from the line III-III in a state where the foil pack is not attached.

  1 to 3 show a foil pack tying member 11 for storing and loading in a receiving portion of a discharge device (not shown), and each component of a multi-component substance is stored separately from each other. Two foil packs 12 and 16 are provided. The foil packs 12 and 16 contain respective components of the two-component substance. In a substance composed of three or more components, a number of adjacent foil pack chambers corresponding to at least one of the foil packs 12 and 16 are provided. With this configuration, a plurality of components can be separated from each other in one foil pack.

  Further, the foil pack tying member 11 includes an integral head portion 21 having a base plate 22, and a first receiving portion 24 for the first foil pack 12 and a second foil portion are mounted on a mounting side surface 23 of the head portion 21. A second receiving portion 25 for the pack 16 is provided. A mixing connection portion 31 protrudes from a side surface 26 opposite to the mounting side surface 23 of the base plate 22, and the mixing connection portion 31 is provided with a screw thread 32 for coupling to a mixing housing 41 having a mixing element 42. . The mixing connection 31 has a first outlet channel 38 having a first outlet for one component in the multi-component material at its free end 37 and a free end 37 for at least one other component of the multi-component material. And a second outlet channel 35 having a second outlet. The first outflow path 38 is divided into two split paths 33 and 34 that are completely separated from each other in the region of the free end 37 of the mixing connection portion 31, and between these split paths 33 and 34, A second outflow passage 35 is disposed. The base plate 22 is further connected to a first communication passage 27 for connecting the first receiving portion 24 to the first outflow passage 38 or the dividing passages 33 and 34, and the second receiving portion 25 is connected to the second outflow passage 35. A second communication passage 28 is provided.

  In the discharge operation by a discharge device (not shown), the foil packs 12 and 16 are opened by, for example, puncturing means or passively by, for example, a weakened portion. The components in the foil pack 16 of the multi-component substance pass through the first communication passage 27, the first outflow passage 38, and the division passages 33 and 34 that are independent of each other. It passes through and is discharged from the foil pack tying member 11 to the outside. As a variation, at least one weakened portion (thin wall portion) is partially provided in at least one foil pack. By doing so, the foil pack is cleaved by the pressure generated by a discharge piston of a discharge device (not shown), for example.

  The cross-sectional shape of the outlet of the mixing connection portion 31 is substantially circular. The cross-sectional shape of both the dividing paths 33 and 34 in a plane extending in parallel with the plane E1 on the base plate 22 is a substantially circular arcuate segment shape, which is the same size as each other.

  The ratio of the total cross-sectional area in the dividing paths 33 and 34 to the cross-sectional area in the second outflow path 35 in the plane extending parallel to the plane E1 where the base plate 22 exists is the cross-sectional area in the first foil pack 12. Corresponds to the ratio of the second foil pack 16 to the cross-sectional area.

  The second outflow path 35 and the second communication path 28 are arranged in parallel to each other in the direction of the plane E1 where the base plate 22 exists, and thereby, between the second outflow path 35 and the second communication path 28. The through-holes 36 for the components in the foil pack 16 touch at least partly or partially overlap in cross section. The division paths 33 and 34 and the first communication path 27 of the first outflow path 38 are arranged parallel to each other in the direction of the plane E1 where the base plate 22 exists, and partially overlap in the cross section. For this reason, the geometric configuration of the head part 21 can be easily produced, in particular, by integrally configuring the head part 21 and / or by injection molding. The monolithic head part 21 can be manufactured, for example, with a simple tool configuration that acts only in the direction perpendicular to the plane E1 on which the base plate 22 exists.
