Definitions

  • the present invention relates to a nose filter, consisting of a porous, elastic body.
  • any such screening or protective means must not obstruct oxygen intake.
  • the object of the present invention is to provide a nose filte which is easily and quickly donned, and which is easily adapt ⁇ able to the size of the person's nostrils, in which the filter is placed.
  • the invention thus relates to a nose filter consisting of a porous, elastic body, and the filter is characterized by the provision in said body of partial, nearly complete lines of separation, such that a part or parts of the body can be removed by tearing them off without causing the body to lose its general shape, or optionally such that slight compression of the body will cause it substantially to reassume its original shape.
  • Figure 1 shows a filter with a separation line and an opening intended for receiving an applicator means
  • Figure 2 shows the filter of Figure 1 in side view
  • Figure 3 shows a filter having three radial lines of separatio
  • Figure 4 shows a filter of alternative shape, seen from above.
  • the filter 1 shown in Figures 1 and 2 is provided with a concentric, circular line of separation 2 extending from the top of the filter almost all the way to its bottom surface.
  • the filter 1 also has a cavity 3 for receiving an applicator means (not illustrated) for facilitating hygienic handling and insertion of the filter into the nostrils of the user.
  • the line of separation 2 does not extend completely through the filter, because this increases the stability of the filter if the user wishes to use the entire filter (in its full circumference) .
  • the outer, peripheral section of the filter up to the line of separation is folded back and pulled off.
  • the attached portion at the bottom of the filter, which is integral with the inner section of the filter, is small enough to permit the outer section easily to be separated from the inner section, yet large enoug to ensure stability of the filter when utilized in full size.
  • a plurality of concentric sections similarly delineated by concentric lines of separation, could be provided to provide a wider range of sizes.
  • Figure 3 shows a second embodiment, wherein the filter 4 is provided with segmental lines of separation 5, extending inwardly from the periphery toward the filter's axis.
  • This filter too, can be provided with an opening for receiving an insertion/applicator means.
  • the lines of separation preferably are radial.
  • Figure 3 shows three segmental lines 5'-, 5 1 ', 5''' which permit the filter 4 to be adjusted to three different sizes, according to the user.
  • the lines of separation in this case, too, are only partially complete; that is, they extend almost, but not quite, to the center of the filter.
  • the filter could be made in a shape other than circular, as seen in Figure 4.
  • this filter can be pro ⁇ vided with several lines of separation.
  • the lines of separation preferably trace a path that is parallel with the circumference of the filter.
  • the invention provides a nose filter which easily and
  • WP hygienically can be placed in the user's nostrils, and with a simple manual operation, the size of the filter can be made smaller, for example for use by children.
  • the filters are preferably neutral, but for use in environments where, for example, odors are a problem, the filter could be provided with a scented substance to counteract the unpleasant odor in the environment.
  • the filters could be provided with medicinal preparations for relieving the condition.
  • the filter itself must be made of a chemically inert and neutral material which will not produce allergic reactions.

Abstract

Un filtre de nez formé d'un corps élastique poreux (1, 4, 6) est doté de lignes de séparation (2) partielles et presque complètes, si bien qu'une ou plusieurs parties du corps, grâce à une simple action de déchirement, peut être retirée sans modifier la forme générale du corps ou si bien qu'une légère compression du corps le forcera à reprendre essentiellement sa forme originale. Les lignes de séparation (2) s'étendent parallèlement à l'axe longitudinal du corps et sont de préférence circulaires et concentriques, s'étendant sur presque toute la longueur du corps.
