Definitions

  • the invention relates to a dispenser for media.
  • Such media may have piece form or be flowable media that are gaseous, liquid, pasty, creamy or powdery or free-flowing.
  • the dispenser is convenient to carry one hand and to press with the supporting hand at the same time for the media discharge. He can only be provided for the one-time media discharge or for any repeatable media outlets. For example, he may return to his starting position by himself after each discharge.
  • EP 0 790 079 A2 shows a dispenser in which a nozzle plate with incorporated swirl device is integrally molded and then displaced into the operating position. When moving to the functional position, the connection is severed by breakage.
  • US Pat. No. 3,685,933 describes a process for the production of plastic articles, in which individual parts are injection-molded in a multi-part mold and joined together after the injection process. The same is shown by FR 2 206 176.
  • the invention has for its object to provide a dispenser, in which disadvantages of known training or the type described avoided or to achieve the benefits mentioned in an appropriate manner.
  • it should be possible to create separation surfaces that are as precisely determinable as possible when the connection is severed.
  • the dispenser should be easy to manufacture and safe to use.
  • the separable connection between the two components is achieved, for example, by shearing or another equivalent separation process. Due to the cutting force profile occurring during cutting in the connection, a slight plasticization of the connecting material and a crack-free or smooth separating surface can be achieved without particles detaching.
  • the maximum separation shear stress should only reach the shear flow limit of the connection material.
  • the separation surface may become grainy and rough. Shear cutting is particularly easy to achieve when the two components are designed as a punch and cutting box analogous to a punch.
  • the construction according to the invention is suitable for numerous components of a dispenser or the like.
  • the components may be two housing parts, such as a main housing and a cover of a pressure cylinder, a pump, a valve, a piston unit, a discharge head o. The like. Or two valve body.
  • the components are sections of a conduit for the medium.
  • the components can be divided transversely or parallel to its axis or against each other in the operating position can be transferred.
  • the connecting member is expediently a projection. It connects in one piece directly to two mutually angled, smooth surfaces of the two components. It extends into the common corner zone of these areas. He connects these surfaces over an inclined surface. It can be flat, concave or convex curved. In cross section, the projection is therefore triangular or isosceles. Its legs connect to the aforementioned pads of the two components.
  • the connecting member is spaced from one or both surfaces facing away from each other of the respective component. Close these surfaces transverse to the associated pad. Thus, no fracture surfaces occur during the cut through at these surfaces. These surfaces form with the pad edges, which connect similar to a mikro Mednen connection directly to the associated edges of the other component.
  • This stapling compound has a much lower strength than the connecting member, such as shear strength. So it can be separated by shear or shaving practically without additional effort. It may already be disconnected if the link has not yet been completely severed. Appropriately, only a single link is provided. Also, opposing links can be provided only on two opposite sides. On the transverse sides are missing such links, but here are the stitching provided.
  • the micro-thin stitch can therefore be closed in a curved or annular manner.
  • adjoining edges of both components at a sharp angle directly to each other.
  • the associated inner surface of a component on the associated edge joint in cross section in a straight line in the outer surface of the other component.
  • the largest cross section of the connecting link is expediently below two, one, half or two tenths of a millimeter.
  • the length of said terminal legs may be e.g. a tenth of a millimeter.
  • the connecting link expediently has constant cross sections. Also, this length is less than one of the above values, in particular a third of a millimeter, so that it is greater than all edge dimension of the cross section of the connecting member.
  • a material is advantageously polyethylene or a material with similar properties.
  • latching or snap-action members are advantageously provided. They jump when the operating position is reached spring-loaded in mutual, positive engagement. Before reaching this working or operating position, they press each other back resiliently. Only one snap element is resilient, while the other remains stable.
  • the respective component can also be secured by a stop on the other component.
  • This stop acts against the blocking effect of the locking member.
  • the stop of a component is expedient only in a last small part of the entire displacement in contact with the other component.
  • the adjoining corner edges of the two components or the associated micro-connection can not be annular. For example, they are interrupted along an unangular continuous edge. Accordingly, the serving as a cutting sleeve guide opening in cross-section on this side be open.
  • the male component is not performed at all on this side on a first part of the displacement. Then he enters a guide part, which leads him positively on this side.
  • this guide page may be overlapped left and right of guide projections. In between, she is free. Between the guide projections, a medium passage is formed. It starts from the opposite guide surface of the receiving component and passes through the recorded component in a straight line. Between these guide surfaces of both components, the medium flows.
  • the connecting member is completely provided after the severing only on a single of the components, in particular on the recorded component.
  • the separation surface of the other component is used over the entire displacement as a sliding surface for the first-mentioned component and ensures its operating position by permanent concern.
  • the cold flow properties chosen of the material used are chosen of the material used.
  • the largest is below thirty, twenty, ten or five millimeters. The smallest of these dimensions is less than five, three, two or one millimeter.
  • the component is therefore a small plate and non-destructive flexurally flexible or flexible. In the operating position, he is then rigidly stiffened by the other component.
  • a media channel that penetrates this component has a smallest width of less than three, two, one or half millimeter.
  • the channel is conical at an angle of less than 5 ° or 2 °.
  • this passage is suitable as a spray nozzle. It forms either the media outlet opening into the open or it lies upstream at a distance from it.
  • All parts according to FIGS. 1 to 6 form a structural unit 1 and are made in one piece with each other.
  • the components 2, 3 are the cap-shaped discharge and actuating head of the piston unit of a pump of the type mentioned and the second component 3 to be accommodated therein.
  • the statements made for the respective component 2 or 3 can also apply to the other component.
  • In the first position and manufacturing form of the part 3 is virtually complete and free on the component 2 before.
  • the parts 2, 3 are immovably connected only via a staple or compound 4. Only after separation or destruction of the stapling 4, the part 3 relative to the part 2 is displaceable. Thereafter, the outermost surfaces of the part 3 close flush and gap to the corresponding outermost surfaces of the part 2. The surfaces are then continuous continuations.
  • a guide 5 is provided. It serves for displacement and is immediately adjacent to the stitch 4, which is partially enveloped by the guide 5.
  • the first and outermost longitudinal section of the guide 5 forms a cutting or hole bushing 6 of a punching tool.
  • the immediately and alone adjoining end of the part 3 forms the associated slide or punch 7.
  • the staple 4 is smoothly sheared off already at the beginning of the mutual movement.
