AN EASILY CARRIED EYE RINSING DEVICE

Abstract: An easily carried eye rinsing device in the form of a flask (1) containing an eye rinsing liquid, wherein the flask is sealed by a closure element (2) which projects up from the future opening of the flask and is provided with an eye cup (3). The invention is characterised in that the eye cup (3) surrounds the closure element (2); in that a sleeve (5) surrounds the eye cup; and in that the sleeve (5) is non-rotatably affixed in the closure element (2).

Description: AN EASILY CARRIED EYE RINSING DEVICE The present invention relates to an easily carried eye rinsing device. By carried is means that it can conveniently be carried about ones person, for instance. A number of different eye rinsing devices which include flasks containing eye rinsing hquid for use in acute circumstances and even in other circumstances are known to the art. These flasks.are often placed in a holder and removed therefrom when needed, wherewith certain flasks are opened as they are taken from the holder. Such flasks are often equipped with an eye cup into which liquid runs from the flask. There exists a need of such flasks that can be carried in the pocket of a garment, in a tool box, or carried about ones person in some other way. It is desired with flasks of this nature that the eye cup and surrounding area are free from contaminants, such as dirt, so that no contaminants will enter the eyes of a user. It is also desired that the flask can be opened and made ready for use with a simple hand manipulation. It is also desired that it shall be impossible to reseal the flask. Resealing of an opened flask would mean that if the contents of the flask have become contaminated and then later used to rinse the eyes of the user, the contaminants might well affect me eye's of me user detrimentally. Flasks constructed in accordance with known technology do not satisfy all of these desiderata at one and the same time. Accordingly, the present invention relates to a flask whose eye cup is protected, which can be easily opened, and which cannot be re-sealed. The present invention thus relates to an easily carried eye rinsing device that comprises a flask which contains an eye rinsing liquid and that is closed by a closure element that projects up from the fiiture opening of the flask, wherein the flask fur- ther comprises an eye cup and wherein the device is characterised in that the eye cup surrounds the closure element; in that the eye cup is surrounded by a sleeve; and in that the sleeve is non-rotatably affixed to the closure element. The invention will now be described in more detail with reference to an exemplify- ing embodiment thereof and also with reference to the accompanying drawings, in which Figure 1 is a side view of an inventive flask; Figure 2 is a top view of the flask shown in Figure 1; Figure 3 is a side view of an inventive flask when provided with a sleeve; Figure 4 is a top view of a flask according to Figure 3; Figure 5 is a sectioned view taken on the line A-A in Figure 3; Figure 6 is a sectioned view taken on the line C-C in Figure 7; and Figure 7 is a side view of an inventive flask taken on the line B-B in Figure 4; Figure shows an eye rinsing device comprising a flask 1 that contains an eye rinsing liquid and that is sealed by a closure element 2 which projects up from the future flask opening. The flask is also fitted with an eye cup 3. According to the invention, the eye cup 3 is situated around the closure element 2, see Figures 5, 6 and 7, and can be turned around said closure element. According to the invention, the device also includes a sleeve 5 that surrounds the eye cup 3. The lower part 6 of the sleeve 5 lies around and against the flask; see Figure 7. This means that the eye cup will be protected by the sleeve against con- tamination by dust and dirt for instance. The sleeve 5 is non-rotatably fixed in the upper part 7 of the closure element 2. According to one preferred embodiment of the invention, the closure element 2 is not axially symmetrical around the longitudinal axis of the flask. In the illustrated embodiment of the invention, the closure element includes two wings 29, 30 that widen. However, the closure element may have a square cross-sectional shape instead. The closure element may, of course, have another non-symmetrical form, such that the flask will be opened when the sleeve, and therewith the closure element, is/are rotated relative to the flask. The closure element 2 includes a waist 8 located beneath said future opening 9; see Figure 1. The lower portion of the eye cup 3 engages in said waist, as evident from Figure 5, by. virtue of projections 10, 11 provided on the eye cup. The eye cup is thus snapped firmly into the waist region of the flask 1. Moreover, an inner part of the sleeve 5 engages around the non- symmetrical part 7 of the closure element 2. This will best be seen from Figures 5, 6 and 7, which show that the upper part of the sleeve includes an inner, downwardly projecting hollow tubular portion 12 that engages around the axially asymmetric part of the closure element. The sleeve 5 is also affixed in the closure element 2 by means of a fastener element 13 that co-acts with said closure element. The sleeve 5 is preferably affixed in the upper part 7 of the closure element 2. Alternatively this fixation can be achieved by an element that grips in the lower part of the closure element 2. The provision of two widening wings 29, 30 on the closure element enables said tubular part to engage effectively with the closure element. The fastener element 13 is generally semi-circular in shape and includes two tongues 14, 15; see Figure 4. The outer shape of the fastener element corresponds in general to the shape of the uppermost part of the sleeve. When the fastener element has been inserted to its end position in said sleeve, in the direction of arrow 16 in Figures 4 and 5, the sleeve and the fastener element will form a smooth and even unit. The upper part 7 of the closure element 2 includes a peripherally extending recess 17. When the fastener element is inserted into the sleeves, the tongues 14, 15 will he in abutment with the recess 17, as shown in Figures 4, 5 and 7. The sleeve 5 is therewith -firmly seated in the flask. The flask 1 is thus provided with an eye cup that is firmly seated in the flask, and a sleeve which is non-rotatably secured in the flask when the flask has not been used. The flask is produced in a first step in the form of the unit shown in Figure 1. The flask is filled with an eye rinsing liquid during manufacture of the flask and then provided with the eye cup, whereafter the, sleeve is fitted and fastened by means of the fastener element, said flask then having the form shown in Figure 3. When the flask is to be opened, the flask is rotated relative to the sleeve, therewith breaking-off the closure element at the future flask opening 9. The sleeve and the upper part of the closure element, which is firmly seated in the sleeve, are thus loosened automatically as the flask is rotated. What remains is the flask with the eye cup attached thereto. The eye cup 3 is then placed over the eye of the user and rinsing liquid flows from the flask when it is turned upside down. The rinsing liquid drains away via V-shaped channels in the short sides of the eye cup. Although the sleeve 5 and that part of the closure element 2 which accompanies the sleeve can be placed back on the flask, it cannot be fastened at said part of the clo- sure element that remains on the flask. Neither can the sleeve be fastened to the eye cup. This embodiment prevents an open flask from being resealed. The flask 1, the eye cup 3 and the sleeve 5 are comprised of an appropriate plastic material. It will be evident that the inventive device fulfils all of the desiderata recited in the introduction. Although the invention has been described with reference to a number of exempli- fying embodiments thereof, it will be apparent to one skilled in this art that the flask can be modified with respect to its structural design. Consequently, the present invention shall not be considered restricted to the afore- described and illustrated exemplifying embodiments, since variations can be made within the scope of the accompanying claims.
