Definitions

  • the invention relates to a paper roll holder for use as a room air freshener, in particular for toilet paper rolls, with an interior and a longitudinal axis which extends horizontally in the operating state. According to a further aspect, the invention relates to a paper roll holding device. In another aspect, the invention relates to a system of a roll of paper roll and a roll of paper held thereon. Finally, the invention relates to the use of a paper roll holder.
  • the carrier material consists of plastic material and the perfume is at least partially distributed in the plastic mass practically molecularly dispersed.
  • the paper roll to be held by the paper roll holding device has a sleeve on which paper is wound.
  • the paper roll holder is inserted through the sleeve and thus carries the paper roll.
  • the paper roll rotates about its longitudinal axis, with the sleeve rubbing against the outer wall of the paper roll holder. As a result, fragrance is released and released into the surrounding air.
  • a toilet paper roll holder which comprises a zy ⁇ -cylindrical body which is inserted into a sleeve on which the Toi ⁇ lettenpapier is wound. Inside the toilet paper roll holder are crystals that emit a fragrance. This fragrance escapes through openings that are provided in the end walls of the paper roll holder and thus refreshes the room air.
  • a disadvantage of the paper roll holders according to the prior art is that when removing paper from the paper roll, which is held on the paper roll holder, although increasingly perfume is dispensed from the paper roll holder, but the additional fragrance konkon in the vicinity of the paper roll holder ⁇ centered.
  • the fragrance passes from there only by diffusion or convection in the surrounding room air to reach the user at some distance als ⁇ embarrassedden; the operation of the paper roll holder itself does not contribute significantly to the fragrance transport.
  • the paper roll holder according to the prior art are also often expensive to produce and therefore relatively expensive.
  • the object of the present invention to propose a paper roll holder, a paper roll holding device, a system and a use which overcome this disadvantage in the prior art.
  • the invention solves the problem for a paper roll holder of the above-mentioned type in that a movable, extending along the longitudinal axis of the paper roll holder membrane element is arranged in the interior, which divides the interior into two chambers, wherein the membrane element is arranged net net that In the operating state during rotation of the paper roll holder is moved about its longitudinal axis so that the volumes of the chambers defined by the Membran ⁇ element change in opposite directions, and wherein the chambers have ge ⁇ possibly closable connection openings for air exchange with the environment.
  • the invention also achieves the object by specifying a paper roll holding device which comprises a paper roll holder according to the invention (preferably in a preferred embodiment, see below) and a receptacle for the paper roll holder for its attachment to a wall.
  • the invention also achieves the object by a system consisting of a paper roll holder according to the invention (preferably in a preferred embodiment) and a paper roll held thereon.

  • a membrane element is understood to be a flexible component whose air permeability is so low that, when an air pressure difference of 1 kPas is present on the membrane element, the air flow through the membrane element is less than 10 1 per square meter per second.
  • the sum of the volumes of the two chambers in operation is constant, ie the volume of one chamber decreases, if the other increases, and vice versa. It is not necessary that both chambers are sealed against each other.
  • An advantage of the invention (in its various aspects) is that odorant can be promoted by an active pumping process. As a result, this fragrance quickly passes from the area of the paper roll holder into the surrounding room air in comparison with the referenced prior art solutions.
  • the pumping power ie the volume flow delivered per unit of time, increases as the rotational speed of the paper roll holder increases.
  • Another advantage is that the pumping effect is achieved by structurally simple means. This allows a simple and therefore cost-effective production of the paper roll holder according to the invention, so that the production is possible as a disposable article.
  • the paper roll holder (or des ⁇ sen basic body) has the outer shape of a straight prism whose base is preferably a regular polygon or a circle.

This ensures that the membrane element fully utilizes the available width of the inner space of the paper roll holder. If the inner space is delimited, for example, by a hollow cylinder, then the contact points extend in a plane with the longitudinal axis of the hollow cylinder. In this advantageous embodiment, when the plane in which the contact points lie extends vertically, the membrane element divides the interior into two (at least approximately) equally large chambers (compare FIG. 7c below).

Abstract

La présente invention concerne un support à rouleau de papier (10) conçu pour être utilisé comme rafraîchisseur d'air ambiant, notamment pour des rouleaux de papier toilette. Ce support comprend un espace intérieur et un axe longitudinal (14) qui est horizontal lorsqu'il est en service. Selon cette invention, un élément de membrane mobile (54) est monté dans l'espace intérieur et s'étend le long de l'axe longitudinal du support à rouleau de papier (10). Cet élément de membrane divise l'espace intérieur en deux chambres (72, 74). Ledit élément de membrane est monté de manière à se déplacer, en service, autour de l'axe longitudinal du support à rouleau de papier (10) lorsque ce dernier tourne, de façon à modifier dans des directions opposées le volume des chambres définies par l'élément de membrane. Les chambres (72, 74) présentent éventuellement des ouvertures de liaison (82) qui peuvent être fermées et sont conçues pour permettre un échange d'air avec le milieu ambiant. Cette invention concerne également un système constitué d'un support à rouleau de papier et d'un rouleau de papier maintenu sur celui-ci, ainsi qu'un dispositif de maintien de rouleau de papier et l'utilisation d'un support à rouleau de papier.
