cleaning quantities of bottles or of other hollow articles of one kind B08B9/00; laundry D06F); SUCTION CLEANERS IN GENERAL (cleaning in general B08) ## Abstract The invention relates to a holding plate for a vacuum cleaner filter bag having a bag wall, the holding plate including a base plate made of a first plastic material with a passage opening, and a connecting element that is connected to the base plate by a material bond and is made of a second plastic material, for connecting the base plate to the bag wall by a material bond, in particular by means of ultrasonic welding, characterized in that the connecting element is arranged on the side of the base plate that is to be connected to the bag wall. ## Claims ### Claim 1 A holding plate for a vacuum cleaner filter bag with a bag wall, the holding plate comprising: a base plate comprising a first plastic material, wherein the base plate comprises a passage opening, and one or several energy directors for ultrasonic welding on the side to be connected to the bag wall; a connecting element comprising a second plastic material connected to the base plate by a material bond, the second plastic material being different than the first plastic material, the second plastic material comprising an injectable material so that the connecting element is injected to the base plate, the connecting element for connecting the base plate to the bag wall by a material bond; wherein the connecting element is arranged on a side of the base plate to be connected to the bag wall so that the connecting element is positioned between the base plate and the bag wall when the holding plate is connected to the bag wall, wherein the holding plate is an injection-molded part. ### Claim 2 (depends on 1) The holding plate according to claim 1, wherein the first or the second plastic material comprises a thermoplastic. ### Claim 3 (depends on 1) The holding plate according to claim 1, wherein the second plastic material has a higher melt flow index than the first plastic material. ### Claim 4 (depends on 1) The holding plate according to claim 1, wherein the second plastic material has a lower melting temperature than the first plastic material. ### Claim 5 (depends on 1) The holding plate according to claim 1, wherein the connecting element is continuous or interrupted. ### Claim 6 (depends on 1) The holding plate according to claim 1, wherein the connecting element is arranged to partially or completely surround the passage opening. ### Claim 7 (depends on 1) The holding plate according to claim 1, wherein the base plate comprises an indentation and the connecting element is partially or completely arranged in the indentation. ### Claim 8 (depends on 1) The holding plate according to claim 1, wherein the connecting element is arranged in a region of the base plate which is at least partially or completely restricted or surrounded by energy directors. ### Claim 9 (depends on 1) The holding plate according to claim 1, comprising a sealing lip for the passage opening in the holding plate. ### Claim 10 (depends on 1) A vacuum cleaner filter bag with a holding plate according to claim 1. ### Claim 11 (depends on 10) The vacuum cleaner filter bag according to claim 10, wherein the bag wall is connected with the base plate of the holding plate, by a material bond. ### Claim 12 (depends on 1) The holding plate according to claim 1, wherein the material bond connecting the base plate to the bag wall comprises an ultrasonic weld. ### Claim 13 (depends on 1) The holding plate according to claim 1, wherein the second plastic material has a melt flow index higher than the first plastic material by a factor of 10 to 20. ### Claim 14 (depends on 1) The holding plate according to claim 1, wherein the connecting element is linear. ### Claim 15 (depends on 9) The holding plate according to claim 9, wherein the sealing lip consists of the same material as the connecting element. ### Claim 16 (depends on 1) The holding plate according to claim 1, wherein the holding plate comprises a molded part made by two-component injection molding. ### Claim 17 (depends on 1) The holding plate according to claim 1, wherein the one of several energy directors comprise one or several elevations on the surface of the base plate extending outward from the surface of the base plate, the one or several energy directors positioned between the base plate and the bag wall when the holding plate is connected to the bag wall.
