Definitions
- the present invention refers to packaging.
- a certain number of these disposable containers is, for example a stililey eye bottle consisting of a molded plastic container for medical liquid and a fully molded dropper tube, the latter being sealed using a cap in separate plastic.
- a dropper bottle which consists of a molded plastic container, a fully molded dropper and a screw cap.
- the present invention provides packaging for the product which comprises a closed container containing the product, the container consisting of a cavity formed by sealing two or more layers of a non-rigid sheet material to define the cavity therebetween, a dispensing tube which has an inner end opening into said cavity and an outer end sealed from the outside by said sheet material so that, in use, the package can be opened tearing the sealed place at the outer end of the dispensing tube and the product can then pass through the tube.
- This type of packaging according to the invention is simple and of low manufacturing cost, moreover the entire dispensing tube is protected from contamination since it is sealed from the outside by said sheet.
- the packaging can be formed, for example, by folding a simple non-rigid sheet and sealing its edges.
- the two or more layers which define said cavity can be two or more pieces of a single sheet. It is also possible to seal any number of separate sheets together, if this is more suitable for packaging the product in question.
- the packages which consist of only two separate sheets are the simplest and least costly to produce, are therefore those which are preferred.
- Said sheets can be of any suitable material, for example metal or plastic sheets and they can be sealed together using any suitable method, for example by welding or gluing.
- One of the best methods of sealing is to apply heat to cause the sheets to merge with each other. If this method is used, it is desirable to use an easily thermoformable material such as a suitable plastic; it is then possible that an additional external layer is necessary for a sheet of sufficient strength to be obtained. It may be advantageous in certain cases to use materials which can be sterilized, for example by heat or radiation.
- One of the most suitable materials for sterilization by exposure to radiation is a laminate consisting of a layer of low density polyethylene and a layer of Kodar PETG Copolyester 6763 from Eastman Kodak.
- the size of the container defined between the layers of the sheet can be increased if desired during its formation, for example by injecting compressed air inside said cavity.
- the dispensing tube which is preferably rigid, can be of any suitable material; it is preferably molded from a plastic such as polyethylene.
- the shape of the dispensing tube required will depend to some extent on the nature of the product contained in the package.
- the internal diameter of the tube for example, will it depend on the consistency of the product.
- the internal diameter should preferably be small enough so that one can be sure that the product can only escape if pressure is exerted on the packaging.
- the outer end of the tube can also be formed so that the best possible control can be had when the product is allowed to flow from the package in which it is found.
- the dispensing tube is well adjusted between the different layers of sheets, it may be held tight enough in good position for some uses. For some applications, however, it is advantageous that the tube is attached to one or more of the sheets. If the sheets are formed of a suitable thermoformable material, this can be achieved without inconvenience by welding the dispensing tube to the sheet / sheets.
- the outer end of the dispensing tube can be sealed from the outside by simply stretching one of the sheets through the opening of the tube; the packaging can then be opened by tearing at this layer.
- notches are formed or perforations are made in the sheet.
- the sheet which constitutes the packaging is shaped with a weaker zone which serves as a tear line so that the outer end of the dispensing tube can be uncovered by tearing the sheet completely. along the tear line.
- said tear line is formed only in the layer giving the strength of the laminate, so as not to weaken the seal formed by the other layer.
- the layer giving the solidity can be perforated or pierced to form said tear line, however when it is not a laminate, it is done throughout the entire thickness.
- a certain number of packages can be inserted inside a sealed container, for example laminated with aluminum foil, to extend the shelf life of the package.
- the packages according to the invention are used mainly in the medical field, but nevertheless there are other fields in which they could be advantageously used, for example the packaging of certain reagents for use in the laboratory.
- the packages according to the invention are particularly suitable for products which must be stored and used under sterile conditions, they can also be useful in other fields where sterility is not essential but when there is has the advantage that the product is packaged in single doses and when it is desirable to include a dispensing tube in the packaging. Examples of this type of product could be given those which deteriorate on contact with air, for example certain types of glue.
- the present invention also extends to a packaging assembly consisting of several units as described above, connected together but which can be separated, in the form of a strip for example. It would be interesting if all the units of this type of packaging assembly were made up of the same two layers of sheets, sealed together in an appropriate manner to define the different containers and to make it possible to separate them one by one. on the other by lines of perforations for example.
- the invention relates to a method which makes it possible to manufacture a packaging for a product which consists in partially sealing together two or more layers of a non-rigid sheet so as to form in the middle of these layers a cavity having one or verture in a certain place, to insert a dispensing tube in the cavity at the level of said opening, to fill the cavity with the product then to finish the sealing of all the layers together, in order to seal said dispensing tube from the outside.
- the type of sheet material used is preferably a laminate as mentioned above and in such a case the size of the cavity can be advantageously increased, by injecting compressed air into the cavity before inserting the dispensing tube. .
- the sheet used is to be designed with a tear line as described above, this can be done at any stage during the manufacture of the package, but it is preferable that this is done before the sheet is sealed so as to form said cavity. If a laminate is used as the sheet, it is preferable that the weakening of one of the laminate layers is carried out before the laminate is formed, to avoid damaging the other layer.
- a strip of units of the product according to the invention in the present case a dropper bottle for the eyes, is formed from a laminate sheet with a thickness of 25 microns of a low density polyethylene (inner layer) and a laminate sheet with a thickness of 125 microns of Eastman Kodak Copolyester (outer layer).
- the zones 2 of the sheet 1 are heat sealed together to define, in each unit, a container capable of receiving the product in the form of a cavity -3- in the middle of the sheets.
- the dropper tube is held securely in position by heat sealing it to the inner layer of one of the sheets -1-.
- One of the sheets -1- is slightly longer than the other sheet, at 7, so that when the packaging has to be opened the two sheets can be easily separated and folded outwards as shown in the figure 3, so as to expose the end -6- of the dispensing tube and thus allow the medicine to pass by pressing the walls of the cavity -3-.
- the two sheets are pierced at level 8 to limit the separation of the sheets as shown in Figure 3, ensuring that the cavity is not exposed.
- the dropper tube is rounded at its outer end -6- to avoid accidentally damaging the eye. Information such as lot number and expiration date can be given at point 9.
- the individual packages are easily separable from the tape by tearing along the perforated lines -10-.
- FIG. 4 schematically shows a method which has the preference for forming a continuous strip of units of the type indicated in FIGS. 1 to 3.
- phase A the hatched areas -2- of the sheets are heat sealed together.
- the cavity is formed by injecting compressed air into the opening - 11-.
- phase B the dropper tube is inserted inside the cavity using a piston.
- phase C the dropper tube is welded at level 12 to the inner layer of one of the sheets or of the two sheets -1-.
- phase D the cavity is filled with the product -13-.
- phase E the end -11- is closed by another heat sealing of the sheets -1- and the information which it is desirable to give is found at 9.
- the sheets are perforated at the point 8 as before mentioned and the perforations -10- are made in such a way that it is possible to separate each of the units.
- the areas -2- of the sheet -1- (indicated by hatching in the central packaging in FIG. 5) are heat sealed together to define, in each packaging, a container for the product in the form of a cavity -3- formed between the leaves.
- the dropper tube is held securely in position by being heat sealed to the inner layer of one of the sheets -1-.
- tear line -14- is formed over the entire thickness of the right side of the packages, as shown in Figure 5, which allows the appropriate part of the sheet to be twisted and removed by a user, as indicated in Figure 7.
- the tear line is obtained by forming a pre-cut line -15- on the outer layer of the laminate forming each of the sheets -1-, as shown in Figure 6.
- a line of perforations can be made in said layer.
- the pre-cut line or the line of perforations should preferably be designed during the manufacture of the sheet, before the two layers are glued by lamination.
- the tear lines on the respective sheets forming the package should be aligned with each other as close as possible during assembly of the unit, although we have realized that a lateral spacing of 2mm maximum created no problem.
- the holes -16- are punched through the sheets -1- so as not to leave any sharp corners after the opening of the packaging.
