Definitions

  • ABSCT A respirator package includes a container having a [22] Filed:
  • a respirator pan is May 20, 1969 Germany....................
  • P 9 25 6225 placed in the bottom portion over an interiorly projecting ridge which is defined around the circumference of the bottom thereof so as to hold the respirator pan or pot so that its walls are spaced upwardly from the bottom and inwardly from the side walls of the lower portion of the container.
  • This invention relates in general to the respirator devices and in particular to a new and useful respirator package including a container having two interengageable parts which engage over a respirator enclosed therein and provides a sealing and holding action with a deformable material placed between one of the parts and the respirator.
  • the intermediate layers protect the respirator against damage when the container is dented.
  • the intermediate layers also provide a possibility for breathing into the respirator through its connecting piece if it should be impossible to remove the respirator from the standby container.
  • the inhaling air can flow at the upper edge of the standby container in the space defined between the container and the respirator and between the intermediate layers of the cushioning material for flow into the inlet ports of the respirator.
  • the intermediate layers 'of cushioning material are made of flexible resilient materials such as felt.
  • respirator In the manufacture of respirators it is very difficult to hold the dimensional tolerances even in mass production so that there is generally a large variation of the outside dimensions of such respirators.
  • a respirator willcomprise at least two parts which are connected with each other after they have been filled.
  • the present invention provides a respirator package which does not use intermediate resilient layers which will render the removal of the container difficult or impossible, but means which provide for firmly securing the respirator unit within the container so that it is free of movement and will not be displaced even when the tions which extend around the circumference at the interior periphery of the bottom wall and which supports the pot and the respirator such that the interior walls of the container are spaced from the walls of the respirator at all locations except in those locations contacted by the support.
  • the top cover portion is engaged with the bottom cover portion over a deformable material which is positioned between the top of the respirator and the top cover portion. The connection is such that the material is deformed so as to hold the respirator tightly within the container and to lock it in a fixed position without play.
  • the material is advantageously a. material which will harden after it is initially compressed and interengaged between the respirator and the container top.
  • the deformable material of course may be a resilient type material which does not necessarily harden after it is interengaged between the container top portion and the respirator. In .both arrangements, the material prevents not only a movement of the respirator in the direction of the deformable material, but also any lateral movement of the respirator or of the supports for the respirator in the bottom container portion.
  • the deformable material advantageously comprises a material which does remain elastic after hardening.
  • the container is supported between projections defined on the lower part, and a deformable member is interposed between the respirator and the container top portion so that there is a firm holding of the respirator within the container in a position in which it is not subject to damage even when there is a denting of the container parts.
  • a deformable member is interposed between the respirator and the container top portion so that there is a firm holding of the respirator within the container in a position in which it is not subject to damage even when there is a denting of the container parts.
  • the construction of the invention it is still possible to breath into the respirator after removing the plate of the respirator which covers the mouth piece. The air can then flow through the intervals which remain between the mounting projections on the bottom portion of the container and the respirator body.
  • the projections are formed by elements which are interrupted to permit interflow in the wall spaces between the container and the respirator body, but if this security is not desired, the mounting projection on the bot tom wall of the container may be made of a single annular piece.
  • the invention also provides a method for the production of a respirator which is to be housed in a container.
  • a hardenable material is ap plied to the upper end face of the respirator.
  • the top cover portion is applied over the bottom portion of the container and the hardenable material is put under pressure by the cover by an amount which is regulated by the spacing between the interior of the cover and the top of the respirator and by the amount of material which is placed therebetween.
  • the cover is placed in position and fully closed the material is permitted to harden or it is vulcanized.
  • the inventive method and apparatus permits the exact selection of a retaining force for the vaporizer body with a selected vacuum lock, that is, with a closing force corresponding to the pressure difference between the interior and the exterior of the container.
  • respirator package wherein a respirator body is held within a container by a deformable material interposed between the body and the cover portion of the container.
  • a further object of the invention is to provide a respirator package which includes a lower portion having an interior projection providing a supporting base for a respirator for holding the respirator with its wall spaced from the interior walls of the bottom portion of the container, and including an upper portion engaged over the bottom portion and over a deformable material which is placed between the respirator body and the upper portion and which is compressed therebetween to form an exact centering and holding engagement of the body of the respirator within the container.
  • a further object of the invention is to provide a method of producing a respirator package which comprises inserting a respirator body into a package lower portion, applying a deformable material over the top of the respirator body in an amount so that it will project upwardly from the top of said body, placing a cover onto the bottom portion and engaging the cover with the intermediate material to compress the material between the cover and the body, and thereafter permitting the material to harden for holding the respirator in an exact position.
  • a further object of the invention is to provide a respirator package which is simple in design, rugged in construction, and economical to manufacture.
  • FIG. 1 is a sectional view of a respirator package constructed in accordance with the invention
  • FIG. 2 is a view similar to FIG. 1 showing the container in a closed position
  • FIG. 3 is an enlarged partial sectional view indicating the interengagement of the top cover portion over a respirator in accordance with another embodiment of the invention.
  • FIGS. 1 and 2 the invention embodied therein in FIGS. 1 and 2, comprises a respirator package generally designated 20 which includes a lower container portion of substantially cylindrical form which is closed by a top container portion 3 of complementary form.
  • a respirator generally designated 1 is arranged within the lower portion 2 and it includes a bottom body part or pot 7 which is located over a projection 5 which is defined around the circumference of a bottom wall 6.
  • the bottom wall 6 may advantageously alsocontain a projection or support 24 which is centrally arranged.
  • the projections 5 and 24 may be formed as a single piece with the projection 5 extending around an annular margin adjacent the bottom wall periphery or each may be made of separate portions of predetermined extent in order to define intermittent fiow passages therebetween.
  • the projection means which are carried by the lower container portion 2 and which are indicated in the form of the projections 5 and 24 hold the respirator 1 such that there is an air gap 8 defined between the walls of the pot 7 and the interior wall of the lower portion 2 of the container.
  • the spacing 8 is sufficiently large to permit the oxygen breathing filter of the respirator l to be removed and to permit operation of the respirator without any hinderance. This also permits use of the respirator even if the container parts are dented.
  • the respirator 1 includes a mouth piece housing or upper part 9 which forms a breathing filter and it is provided with a rubberized or similar elastic coating 10.
  • the top of the respirator 1 at the location at the top of the mouth piece housing 9 is indented or provided with a depression 11 and a deformable material or plastic piece 13 is positioned on this indented portion.
  • the top cover portion 3 is provided with an inwardly directed portion or projection 12 which is centered over the plastic piece 13, as indicated in the partially closed position shown in FIG. 1.
  • the cover 3 is moved downwardly to engage with and close against the bottom portion 2. This causes the plastic piece 13 to deform to the configuration indicated in FIG. 2 after the cover 3 is connected gas tight with the lower portion 2 of the container and the closing is effected.
  • the plastic piece 13 is such that after it deforms it maintains its deformed condition as indicated in FIG. 2 and hardens in this form to provide a firm holding and positioning action on the respirator 1 within the container.
  • the plastic piece 13 advantageously engages in the recess in the top of the respirator and also over a shoulder portion 12' of the projection 12 of the cover 3. This ensures that the.
  • respirator body will not be displaced in any direction including laterally.
  • a respirator body 1 is held in a position within a container by a top cover 3' which is pressed down over a plastic piece 13' which is of a material which does not harden but which provides a resilient deformation and a firm interengagement of the respirator body 1' by the cover 3'.
  • the material of the plastic piece 13' may, for example, be a rubber or a plastic material, such as a foam. In some instances, it is advisible to insert a layer of material 24 between the plastic piece 13' and the cover 3' and a layer of a material 26 between the plastic material 13' and the vaporizer body 1.
  • Such layers 24 and 26 may comprise non-sticky materials or materials selected so that there is no sticking between the container cover or the respirator 1 after hardening or vulcanization of the plastic piece 13' in those instances when this piece is made of such a hardenable material.
  • Layers 24 and 26 may for this purpose comprise foils of non-sticky materials such as paper, etc.
