Abstract of the Disclosure This invention relates to a device for applying a sterile liquid to a sore or a part of the body such as the eye. A container having a container body made of flexible material is provided with an outlet equipped with a tubular emptying device which is provided with a breakoff weakening zone. Adjacent to the outlet there is a contact member with one or more strip-shaped contact surfaces. The breakoff weakening zone is located closer to the container body than the contact surfaces. The contact member is provided with drainage openings in the area between the contact surfaces and the point at which the member is attached to the container body. To apply sterile liquid to the area being treated, the emptying device is broken off at the breakoff weakening zone and, after being broken off, the emptying device is directed towards the area to which the liquid is to be applied.
The flexible container body is squeezed and the liquid is pressed out through the broken-off emptying device.
The contact member prevents direct contact between the sore or other part of the patient's body being treated and the tubular emptying device, and simultaneously the applied liquid is drained from the area being treated by means of the drainage openings. This invention minimizes risk of mechanical injury to the area being treated and minimizes risk of contamination of the sterile liquid.

PP 564 uans A/S Haustrup Plastic, Langeskov, Uenmark Container for sterile liquid This invention relates to a device for applying a sterile liquid to, for example, a sore or a part of the body such as the eye, wherewith a container having a container body made of flexible material is ar-ranged together with a tubular emptying device provided with a break-off weakening zone used to open the sealed and filled container and, more specifically, arranged so as to provide a contact member having one or more contact surfaces adjacent to the emptying device so that, when emptying an opened container the liquid, being applied to the sore or part of the body, will remain substantially sterile while simul~aneously avoiding direct contact between the area to which the liquid is being applied and the emptying device.
In many situations, medical situations for example, a need arises to apply clean or sterile liquid to an area or part of the body. Par-ticularly dt work sites where there is risk that an unsuitable sub-stance will come into contact with the area around the eye, the need to apply a clean or sterile liquid to such an area is well-known.
When, as an exampleD an eye has become contaminated, it can often be difficult for the person in quPstion to see, and it is thus especial-ly important to have equipment which will make certain that the per-son in question will not risk damaging himself even more as a result of the steps he takes, even if he is temporarily unable to see.
~1~
This invention meets the need cited above, and its purpose is to provide a container that can be used to apply sterile liquid to, for example, an eye or a sore, wherewith the container is so designed that it can be opened without the operator coming into contact with the emptying opening thus created and also so that during use it will permit the liquid to leave the area being treated immediately. The first-mentioned feature thus prevents the operator from contaminating the emptyin~ opening and this, in turn, makes certain that the liquid that leaves the emptying opening will be satisfactorily sterile. The second feature reduces the risk that the li~uid will accumulate on and thus be contaminated by contact with, for example, the skin in the area adjacent to the sore.
A construction in accordance with the present invention comprises an attachment for a container, wherein the container includes a body, an elongated tubular closed member extending from the body a predeter-mined distance therefrom. The attachment i-tself com-prises collar means for securing the attachment to the base o~ the tubular member, contact means in the ~orm of a substantially annular ring having a smooth contact surface being spaced from the collar a distance less than the exten-t of the tubular member, and rigid strut rneans extending between the collar means and the contac-t ring for supporting the contact ring about the ~2~37716 _ 2a -tubular member and defining drainage openings there-between. The tubular member defines a frangible annular area thereon between the collar means and the distance o-f the contact ring, with the tubular member projecting beyond the contact ring a distance such that it can be grasped and broken away at the frangible area to form a dispensing spout inwardly of the contact ring.
A device as per this invention makes use of a container that has a container body made of flexible material and an outlet provided with a tubular emptying device that is equipped with a breakoff weakening zone that is used to open the sealed and filled container.
~oreover, the device has a contact member located adja-cent to the emptying device and preferably surrounding the emptying device throughout an area adjacent to the container body and provided with one or more strip-shaped and preferably circular contact sur~aces. The contact surfaces are located further from the contalner body than the breakoff weakening zone. The contact member is provided with drainage openings located between the point at which the contact member is attached to the container body and the contact surface or surfaces and, whenever applicable. be-tween them.

The container used in this invention is~ in one version, provided with a separate filling device, while in a second version the empty-ing device also serves as a filling device for the container.
When the-container is being manufactured, the filling device or filling/emptying device is sealed initially in connection with manu-facturing, after which the container is rnoved to a filling station at a site which is, as a rule, separate from the production site, and where the filling device is opened, preferably either cut off or broken off at a special breakoff weakening zone or score. The con-tainer is then filled with liquid after which the filling device is sealed a second time, preferably by means of a welding procedure. In the version of the invention in which the emptying device also serves as a filling device9 the length of the devi~e is selected so that even after the container has been filled and re-sealed, the device projects somewhat beyond the contact surface or surfaces.
When liquid is to be emptied from the container, the emptying device is broken off at the breakoff weakening zone or score after which the container is positioned adjacent to the area to which the liquid is to be applied. In this connection3 it i5 advisable to permit the contact surface or contact surfaces to rest adjacent to or to sur-round the area. The container body is then squeezed, and the liquid is applied to the area. The contact member makes certain that nei-ther the operator nor the area to which the liquid is being applied comes into contact with the broken-off opening in the emptying de-vice, and additionally the openings in the contact member are drain-37~16 ing liquid from the area. This makes certain that the liquid located in the area being treated is contaminated as little as possible.
In one version of the invention, a constriction is arranged in the tubular emptying device at a location between the breakoff weakening zone and the container body. This constriction reduces the flow-through area of the emptying device and thus prevents the outgoing liquid jet from becoming too powerful.
In a preferred version of the invention, the contact member incorpor-ates a ring which supports the contact surface. Moreover, the con-tact member contains a connection device whiGh secures the contact member to the tubular emptying device in an area adjacent to the transition between the emptying device and the container body. A
number of separate jointing elements are used to join the ring to the connection device.
In another version, the connection device is arranged with a projec-tion protruding towards the centre axis of the connection device and snapping into an external groove in the emptying`device.
In yet another version of the invention, the walls of the emptying device, which bound the external groove into which the connection device projection is snapped for attachment to the emptying device, form an internal depression which mates with a groove in the con-striction inside the emptying device. This secures the constriction in the proper position in the emptying device.
This invention is described in greater detail with reference to a number of figures, where )~7~6 Fig. 1 shows a container viewed from the side, Fig. 2 shows a cross-section taken through the container in the area of the emptying device, Fig. 3 shows a front view of the container.
The figures include a container 10 having a container body 11 made of flexible material, preferably a thermoplastic material, a bottom part 12 and an outlet 13. The outlet is arranged in a tubular emptying device 14 provided with a breakoff weakening zone or score 15. The broken lines in Fig. 2 indicate the emp~ying opening 34 that is form-ed after the emptying device has been broken off at the breakoff weakening zone 15. Moreover, a contact member 16 is mounted around the emptying device in an area adjacent to the container body 11.
The contact member has a strip-shapled contact surface 17 loçated in such a way that the breakoff weakening zone 15 is closer to the con-tainer body than the contact surface.
The contact member 16 includes a ring l9 which supports the contact surface 17 and a connection device 22 used to secure the contact mem-ber in position relative to the tubular emptying device in an area adjacent to the transition between the emptying device and the con-tainer body ll. Separate jointing elements 23 join the ring 19 with the connection device 22. Drainage openings 33 are formed between the jointing elements, and these drainage openings permit the liquid to leave the wetted area.
In the embodiment of the invention disclosed in Fig. 2 the tubular emptying device, adjoining the sealed container that is filled with 37~i liquid, is including a constriction 27 in an area between the break-off weakening zone 15 and the transition between tne tubular emptying device and the container body. The constriction 27 has a nozzle 28 with an area and shape that prevents the liquid jet from becoming too powerful and prevents too great a flow from striking the area against which the liquid is directed as the container is being emptied. The wall oF the emptying device which surrounds the constriction 27 forms an internal depression 26 which mates with a groove 29 in the constriction. This secures the constriction in its proper position in the emptying device.
The walls of the emptying device, which the form internal depression 26, also form an external groove 25 in the emptyin~ device. This groove mates with a projection 24 arranged on the connection device 22 and the projection being protruding towards the centre axis of the ~5 connection device and snapping into the groove. This secures the contact member 16 in its proper position relative to the emptying device 14.
Figs~ 1 and 2 present the version of the invention mentioned previ-ously in which the emptying device also serves as a filling device.
The broken lines repr~sent one such sealed or opened filling/emptying device on an unfilled container. Reference number 18 indicates the initial opening oF such a container, carried out by cutting or break-ing at the outermost part of the fillir,g and emptying device 14. The continuous lines represent the filling and emptying device on a con-tainer filled with liquid.
~ 3'7~76 To apply the invention using the version in which the emptying device also serves as a filling device, the container is produced with a tubular filling and emptying device which is longer than that of the container filled with liquid, after which the produced container, still empty, is sealed. Such a sealed container is internally ster-ile.
The container is then moved ~o a filling station where the outermost part of the filling and emptying device is separated. This provides an outlet 18. The liquid is then added to the container via the filling and emptying device. The constriction 27 is then inserted in the filling and emptying device and secured there when the internal depression 26 snaps into th~ groove 29 in the constriction.
The filling and emptying device is sealed and the container obtains the shape that is shown by the continuous lines in the figures. The figures also show that the filling and emptying device 14 extends beyond the contact surface 17, When the filled container is used, it is opened by breaking off the filling and emptying device with the assistance of the breakoff weak-ening zone 15. This forms the emptying opening 34 on the container, 2n and this opening is located closer to the container body than the contact surface 17. The container is then moved towards the area on which the liquid is to be applied, preferably far enough so that the contact surface 17 contacts an area adjacent to the area that is to be wetted by the llquid. The container body 11 is squeezed, where-upon the liquid sprays out through the nozzle 28 on the constriction 3~
B
27 and then through the emptying opening 34 onto the area that is to be treated. The contact member 16 prevents any part of the emptying device from coming into contact with the area that is to bé wetted.
The fact that the design of the contact member incorporates drainage openings 33 permits the liquid to immediately leave the area being wetted9 thus minimizing risk that the liquid will be contaminated by contact with, for example, skin areas adjacent to the area that is to be wetted.
When the invention is applied in the version in which the container 1~ is provided with a separate filling device, the constriction 27 should preferably be inserted as early as the manufacturing stage, and the container should be delivered to the filler with a sealed emptying device designed as shown by the continuous lines in Figs. 1 and 20 The filling device is sealed by the manufacturer and arranged for opening and re sealing in connection with the filling of the con-tainer. Preferably, the filling device should be arranged so that it can be opened and re-sealed in accordanc~ with the techniques which were described above in connection with the combined filling and emp-tying device.
Experiments that have been conducted indicate that this invention will permit a container filled with sterile liquid to be stored for a very long time, on the order of magnitude of up to two years, without adding any preservatives to the liquid. This invention also provides a container that is easy to use, in the event of accidents for exam-ple, while simultaneously eliminating the risk oF making an already-3~
-sustained injury worse as a result of mechanical actlons. Moreover, the container itself does not require any external aids for use, even though the container s design and construction are such that it can very well be used in connection with, for example, specially designed suspension brackets or other devices designed so that, when the con-tainer is removed from the bracket or device, breakoff occurs at the neck, thus opening the container immediately. Such combinations of containers and suspension brackets are particularly suitable in the event that the container is mounted at work sites where it will be of service in the event of injuries caused by, for example, the entry of foreign liquids or foreign particles into the eye.
~y using a contact member having one or more strip-shaped contact surfaces which surround the emptying device and an emptying device having a breakoff weakening zone that is closer to the container body than the contact surfaces and9 in certain versions of the invention, adjacent to the co~tainer body itself, protection is provided against contamination of the internal part of the emptying device in an ef-fective way while the con~ainer is being handled before and during opening. After opening~ the contact surF~ce prevents the internal part of the emptying device from coming into contact with the sore or any other treatment area which could jeopardize the sterility of the liquid that is pressed out. Since the emptying device projects out-side the contact surface, it serves as a steady rest for the emptying device or, alternatively, provides a firm grip on the emptying device during the breakofF operation without entailing risk oF contamination ~3~6 1() of the emptying opening formed by the breakoff operation or contaMi-nation of the remaining internal part of the emptying device. The openings provided in the contact member permit the liquid to leave the treatment area immediately, thus eliminating risk for contamina-tion of the liquid by contact with the skin area adjacent to the treatment area insofar as possible.
The size of the area surrounded by the contact surfaces 17 is adapted to the type of treatment for which the container is primarily intend-ed. For the version, for example, in which the contact surface is circular and where the container is used for cleaning the eye, the diameter of the contact surface is on the order of magnitude of 40-60 mm. For other applications where the con~act member 16 is intended primarily to serve as a device that prevents direct contact and thus contamination of the emptying device 14 in the vicinity of its empty-ing opening 34, contact surfaces having a considerably smaller cir-cumference are selected.

Since the emptying device projects out-side the contact surface, it serves as a steady rest for the emptying device or, alternatively, provides a firm grip on the emptying device during the breakofF operation without entailing risk oF contamination ~3~6 1() of the emptying opening formed by the breakoff operation or contaMi-nation of the remaining internal part of the emptying device. The openings provided in the contact member permit the liquid to leave the treatment area immediately, thus eliminating risk for contamina-tion of the liquid by contact with the skin area adjacent to the treatment area insofar as possible.
The size of the area surrounded by the contact surfaces 17 is adapted to the type of treatment for which the container is primarily intend-ed. For the version, for example, in which the contact surface is circular and where the container is used for cleaning the eye, the diameter of the contact surface is on the order of magnitude of 40-60 mm. For other applications where the con~act member 16 is intended primarily to serve as a device that prevents direct contact and thus contamination of the emptying device 14 in the vicinity of its empty-ing opening 34, contact surfaces having a considerably smaller cir-cumference are selected.
