Definitions

  • ABSTRACT In automatically discharging an effective substance, such as a deodorizing agent, from an aerosol container into a normally closed room, such as a bathroom,
  • the aerosol container is pivotally.
  • a tilting valve forms the discharge member from the container
  • the container can be supported by the holder in the upright or inverted position.
  • a whistle device can be arranged at its outlet opening for providing a whistle tone when the container is empty or a whistle tone can be provided at each discharge from the container so that the tone is no longer emitted when the container becomes empty.
  • the present invention is directed to a device for spraying an effective substance, such as a deodorizing agent, a perfuming agent, an'insecticide and the like, into a normally closed room and, more particularly, it concerns an arrangement for pivotally mounting a container holding the effective substance so that the substance is automatically discharged into the room each time a closure member for an entry way into the room is opened.
  • an effective substance such as a deodorizing agent, a perfuming agent, an'insecticide and the like
  • Devices for discharging effective substances such as deodorizing and perfuming agents, are also known which are used in lavatories, closets and the like and from which a constant discharge of the substance is made into the room in which it is located.
  • a continuous discharge is undesirable because the concentration of the effective substance in the room can become too high due to inadequate ventilation or infrequent opening of the door or entryway into the room.
  • the primary object of the present invention is to provide a device from which the discharge of an effective substance is performed automatically in proportion to the frequency with which the door to a room is opened and closed so that the problem of an undesirably high concentration of the effective substance is positively avoided. Further, in this arrangement the loss of the effective substance from the room at each opening of its door is taken into account by the amount of the substance which is'discharged.
  • the discharge of the effective substance into a room is provided by pivotally mounting a container for the effective substance on the door or other closure member for the room so that the container forms a flywheel mass which opens and closes a discharge member from the container as the door opens and closes. Due to the inertia of the flywheel mass as the door is opened and closed, a practically constant amount of the substance is discharged from the container so that the concentration of the substance within the room does not increase with time, since the addition of the effective substance is proportional .to the frequency of access to the room and thus of its ventilation whenever the door or closure member into the room is opened.
  • the effective substance is discharged into the closet when its door is opened and, similarly the process is repeated when the door is closed, with the discharge occurring normally at the commencement of the closing movement and at the sudden stop when the closed position of the door is reached.
  • the process is reversed, that is, the sudden acceleration which occurs when the door is opened effects a discharge of the effective substance and likewise the sudden stop when the door is closed also causes a discharge of the substance into the room.
  • aerosol spray cans are used as the containers for the effective substance with a tilting valve affording a particularly effective discharge control element.
  • the discharge spray jet can be effected in two different directions corresponding to the pendulum movement of the container and to the tilting action of the valve.
  • This arrangement has the special advantage that it affords a better distribution of the effective substance into the room.
  • various known pumping devices can be used for discharging the substance from the container.
  • the container with a device which prevents any exchange between the atmosphere surrounding the container and the contents of the container when it is located in its normal position.
  • the discharge or spray of the effective substance is provided only when the container is displaced from its normal at rest position. Accordingly, the effective substance is discharged into the room only when its container is displaced from is normal position.
  • such a container can be designed in the manner of a bird bath.
  • the container In addition to pivotally mounting the container on the door, it can be combined'with a pendulum and mounted in a holder on the door so that, as the pendulum is deflected from its rest position, it actuates the discharge member or valve of the container. If necessary, an intermediate lever can be provided between the pendulum and the valve.
  • the container itself can be used as the flywheel mass. If the container should not provide sufficient weight for the mass, particularly as the container is emptied, and especially when it is arranged in an inverted position so that its center of gravity is displaced downwardly, the container can be provided at its base "with a ring or diskshaped weight. Preferably, the weight should be detachable so that it can be used with successive containers and only one such weight need bepurchased.
  • the container for the effective substance is an aerosol can with a tilting valve having an outwardly projecting part of the valve cone arranged to be inserted into a bore in a rigid holder with the container arranged in an inverted position.
  • a similar container and tilting valve arrangement can be used with the container in the upright position and the outwardly projecting part of the cone valve fitted into the bore of a sleeve and secured within the sleeve by a binder, such as cement or other adhesive.
  • the sleeve In supporting the container on a door or similar closure member, the sleeve is inserted into a slot in a forked holder which is rigidly fixed to the door, with a shoulder on the sleeve bearing against a support surface in the holder.
  • the spray jet can be directed downwardly onto a porous, sponge-like member supported in the holder for the container.
  • the effective substance sprayed into the sponge-like member is released into the room in a slow manner by evaporation.
  • the advantage of such a design is found in the extended period over which the effective substance is released into the surrounding atmosphere. If such a release arrangement is located in a closet, a bathroom, a lavatory or the like, on the inner side of the door, the effective substance is discharged from the container whenever the door is opened and closed.
  • the effective substance is released from the container when the door is opened, a portion of the substance would be wasted since the full amount would not be retained in the room which is to be treated. However, if all or a very substantial proportion of the effective substance is absorbed by the sponge-like member, it will be released into the room after the door has been closed.
  • Another advantage of such a device is that the effective substance sprayed into a closet containing garments and the like avoids an excessive concentration of the substance being sprayed directly onto the garments.
  • At least one elastic return element can be provided in operative engagement with the container.
  • the member can be connected directly into the gas chamber located in the top of the container.
  • the arrangement is reversed from that in known aerosol cans which have the discharge element located at the top and a tube connected to the discharge member extending to the bottom of the container, that is into the lower end of the liquid chamber.
  • a spray jet issues for a brief period of time into the room and the spray is composed of liquid (effective substance and unevaporated propellant) and propellant gas.
  • the discharge procedure is repeated until liquid no longer issues in the spray but only the propellant gas.
  • an azeotropic mixture is used, the spraying action continues until the container is completely empty.
  • a whistle or flute-like device which indicates when the effective substance in the container has been used up.
  • a channel leading to a cavity or forming the cavity itself is positioned perpendicularly to the path of the spray jet from the container and its opening is arranged slightly obliquely to and in the path of the spray jet so that a whistle tone is emitted when the liquid contents are completely used up, or if an azeotropic mixture is used in the container, a whistle tone is produced until the container is empty after which the whistle tone ceases.
  • the user of the device notices that the container is empty when the whistle tone commences,'and in the other case notices that the container is emptied when the whistle tone ceases.
  • no whistle tone is produced as long as'the spray jet contains liquid constituents;
  • the liquid contents, that is the effective substance, in the aerosol can is exhausted, only propellant gas issues from its discharge outlet and flows passed the whistle-like device producing the whistle tone. Consequently, a shrill whistle tone is produced when the propellant gas (without any liquid effective substance) is released.”
  • the fact that the can is emptied cannot go unnoticed.
  • the user can be informed by a corresponding reference in the directions of use that the effective substance in the arosol container have been used up when the whistle tone appears and that the empty container should be replaced by a new full one. If an azeotropic mixture is utilized in the container, the signalling operation operates in a reverse manner. When the azeotropic mixture issues from the can, a whistle tone is provided, accordingly, when the whistle tone ceases, a user is notified that the container needs to be replaced.
  • the whistle can be provided in any desired manner, for example, as a recorder, a transverse flute and the like.
  • the simplest solution to the problem is the use of the barrel key principle, consisting of a simple closed channel with the closed channel extending transversely of the path of the spray jet issuing from the container and with the opening to the channel arranged slightly obliquely to and in the path of the jet.

  • the container for the effective substance is exclusively an aerosol can and its discharge member is exclusively a tilting valve, however, the principles of the invention can be utilized as indicated previously, in aerosol cans with normal spray valves, that is, valves which are actuated in the direction of the longitudinal axis of the cans.
  • a pump unit can be used as the discharge member for the container and the discharge member can incorporate a device which prevents any exchange between the contents of the container in its normal at-rest position and the surrounding atmosphere, such containers discharge the effective substance only if they are deflected from their normal position.
  • Containers can also be used which are rigidly secured on a member which can be opened and closed in gaining access to the room or chamber into which the effective substance is sprayed and where the spraying action results from the inertia of the contents of the container which effect the opening of the discharge member.
  • Such containers can be designed in the manner of a bird bath.
  • a closure member 1 provides a movable part through which access is gained into the room in which the effective substance is sprayed.
  • the closure member 1 is a door or the like and a container 2 in the form of an aerosol can is mounted on the closure member.
  • Discharge of the effective substance from the container 1 is provided through a tilting valve 3 having a valve cone 4 which projects outwardly from the container.
  • the container 2 is in an inverted position and the valve cone part 4 is inserted downwardly into a bore 5 in a holder 6 which is rigidly secured on the closure member 1.
  • the spray jet from the container is directed downwardly and is produced by the movement of the closure member in the opening or closing direction due to the pivotal mounting of the container 2 relative to the holder 6.
  • the tilting valve 3 is opened the effective substance exits from the container in a spray jet 7 in the downward direction, as mentioned above.
  • the projecting part 4 of the tilting valve 3 is inserted into a sleeve 8 and is attached to the sleeve by means of a clamping action or by a binder, that is an adhesive material of some sort.
  • the container 2 is arranged in the upright position and its spray jet issues upwardly through the bore 9 in sleeve 8 when the container is pivotally displaced for opening the tilting valve 3.
  • the flywheel moment of the container 2 acting as a flywheel mass, diminishes as the effective substance is used up.
  • a weight 12 in the form of a ring or disk shape member is secured to the bottom of the container by a clamp 11.
  • the clamp 11 and the weight 12 can be removed from the used container and placed on the fresh one so that the weight and clamp can be reused.
  • the holder for the container 2 consists of two parts 13 and 14 spaced apart in the vertical direction, and the flywheel mass consists of a pendulum with a downwardly extending arm 15 having a weight 16 secured to its bottom end.
  • the pendulum arm 15 is pivotally mounted on the upper holder part, or if necessary, on the top of the container 2 itself and it actuates the tilting valve 3 either directly or through the medium of an intermediate lever 17. In this arrangement the spray jet from the container is directed upwardly,-in the same manner as in FIG. 2.

  • the effective substance when the effective substance is sprayed from the container 2, it is directed toward the sponge-like member and all or most of the substance is absorbed by the member. As a result, instead of being directly sprayed into the room, the substance evaporates slowly from the member 23 and is released into the room.
  • an aerosol can serves as the container 2 for the effective substance and the discharge member is a tilting valve 3, however, the principle disclosed in this embodiment can be used in the same manner with spray cans having a normal spray valve, that is one which is actuated in the direction of the longitudinal axis of the aerosol can and also in containers which utilize a pump unit as the discharge member.
