Portable sprayer without protective overcap, ready for use.

p0001The present invention relates to a device for spraying products, more particularly to such treatment of seizure-like disease states. It is designed so that the necessary for the spray devices used previously removing a cap to expose the spray head is omitted, the sprayer is ready to use and the device is transportable in previous form even without such a cap, so that the patient in the pocket can be worn without the risk of the valve to be operated inadvertently or suspend the spray head to excessive mechanical stress, which often results experience has shown that this is either stripped or broken off together with the core pipe.

p0002Aerosol Aerosols consist of an open-topped pressure vessel, to set up a valve and in an appropriate manner, eg., By Ankrimpen, is attached. The valve has a called "Stem" designated nozzle that is protrudes with one end into the dosing chamber and placed on the other via the valve capsule also projecting end of the spray head. Actuation of the aerosol dispenser is done by depressing the spray head. The pressure difference between the pressure prevailing in the interior of the tank pressure and the atmospheric pressure causes thereby the contents of the container is released in the desired quantity. The technical rules for pressurized gases (TRG 300) provides that such devices during transport must be gechützt against inadvertent operation of the spray head in an appropriate manner. This is usually accomplished by placing a cap which is locked by appropriate measures either on the pressure vessel or on the valve cap. For small, intended for the treatment of paroxysmal extending diseases Aerosols, which are constantly carried by the patient generally, the rapid application more difficult of an impending attack by the previous removal of this cap.

p0003In the then üolichen excitement of the user, the protective cap is often removed only by lateral buckling, which moves in many cases for stripping the spray head from the star, or even to cancel the stem with the seated thereon spray head. Thus, the entire device is no longer functional and the protection of the patient is no longer guaranteed.

p0004The present invention relates to a device for the application of such seizure preparations in which a cap is no longer used in the form described above with all its disadvantages, further, the nozzle opening of the spray head is protected from contamination, accidental depression of the spray head is surely prevented and spray head and Stern are protected from unwanted cancel.

p0005The erfindungsgemäßge device comprises, like the prior art devices, one intended for receiving of the pharmaceutical product pressure reservoir (1) and a valve having a one - pushable star (5) and a seated thereon spray head (4) with laterally arranged nozzle (10) and is characterized in that it comprises an on-the valve capsule (6) aufgestzte protective sleeve (2), which is so high that its upper, ie from the storage container (1) more distant edge at the height of the upper edge (3) of the the spray head (4) in the quiescent state of the device or only slightly closer to the reservoir (1) is situated, the protective sleeve (2) in the lateral wall an opening (9) at the point at which the depressed state of the spray head (4) comes in this laterally arranged nozzle (10) to stand, the inner diameter of the protective sleeve (2) at least in the upper part of the outer diameter of the spray head (4) corresponds in such a way that the latter is made herein in its pressing-in, and the spray head (4) and the inner wall of the protective sleeve (2) interlocking guide elements (7, 8), so that the spray head (4) is prevented during the push-in movement or during its return movement to the rest position against rotation about its longitudinal axis and the protective sleeve (2) by suitable measures is held substantially not be removed on the storage container (1).

p0006The inventive apparatus is illustrated in the accompanying drawings.<ul><li>Figure 1 shows a side view of the device with the outlet opening in the protective sleeve in the rest position</li><li>Figure 2 shows a side view of the device by 90 ° to Figure 1 rotated at rest</li><li>Figure 3 shows the longitudinal section AA through the device in the rest position in the upper part of Figure 1</li><li>Figure 4 shows the Längsschnitt.AA through the device in the actuated state</li><li>Figure 5 shows the section BB through the apparatus in height of the nozzle in the actuated state according to Figure 4</li></ul>

p0007In the normal state ready for use, the device of the invention from the prior art devices is different in that it does not have a conventional closed cap, but on the pressure vessel (1) the protective sleeve (2) which is open at the top, releasing the upper bearing surface (3) of the the spray head (4). The protective sleeve (2) is carried out so that the rating on the (5) seated spray head (4) can be operated easily with one finger. The solid composite of the protective sleeve (2) with the reservoir (1) may, without limiting the invention, for example, take place in that the inside horizontal circumferential ribs are arranged in the lower region of the protective sleeve, which engage behind the lower edge of the valve capsule. Rotation of the spray head (4) about its longitudinal axis is prevented that on the inside of the protective sleeve (2) a guide element (7) is provided in the longitudinal direction of the device whose length at least to the stroke of the spray head (4) corresponds to during the operation process. On the outside of the spray head (4) a guide element (8) is provided at the appropriate place, that the in combination with the guide element (7) allows a vertical movement of the spray head (4), but the radial movement is prevented. Also located in the protective sleeve (2) has an opening (9) at such a height that in the spray head (4) conventionally provided lateral nozzle (10) in herunterge2 [engaged state before this opening (9) comes to lie.

p0008This ensures that in the unactuated state, the nozzle (10) is located in the interior of the protective sleeve (2) and is protected hereby, while it comes to rest at the moment of the actuation front of the opening (9) of the protective sleeve (2). The specially designed protective sleeve (2), thus preventing not only unintended stripping of the spray head (4) and not only protects the same time the nozzle (10) from dirt and damage, but enables immediate application of this medication without first removing a cap and also ensures safe whereabouts of the spray head (4) with the nozzle (10) on the star (5).
