Definitions

  • the invention relates to a hood unit for closing bottles, in particular medication bottles, which has a dropper tube and a cap placed over it, through which the dropper tube can be resealed after opening, the hood unit being inseparable from the bottle in its original state.
  • hood unit according to DE-OS 27 43 270 this is, for. B. achieved in that the upper part of the hood is firmly attached to a lower part and this lower part encloses the bottle neck. There is a weakened wall area in the upper part of the hood, so that when a transverse force is exerted, this upper part bends or breaks off. This is to prevent the hood unit as a whole, that is to say the lower part and the upper part, from being levered off the bottle neck without damaging the hood unit.
  • the correct opening is carried out by pulling off a separating ring, whereby the fixation of the upper part of the hood to the lower part is released. This original type of opening also destroys the original condition of the hood.
  • DE-OS 32 15 522 also describes a two-part system in which the upper part and lower part of the hood unit are connected by toothed ridges in the original state.
  • - sealing surfaces between the upper part and lower part of the hood unit must ensure the required quality of sterility even with long storage times.
  • the example shown here has a combination of multiple, complex structured sealing surfaces.
  • the first opening is carried out by pulling off a separating ring in the weakened area of the hood cap.
  • a disadvantage of these constructions is that the ear, which is attached to the separating ring in order to be able to pull it off, can tear off due to improper handling during storage or during attempts to open it. In this case, opening the bottle is difficult. Because the hood unit is in two parts even in the unopened original state and the sterility of the contents of the drop bottle must also be guaranteed over often longer periods of unopened storage, multiple and complicatedly arranged sealing surfaces are necessary to ensure the required sterility of the container contents. In addition, it is necessary to keep the tolerances of the sealing surfaces consistently small even in the case of large quantities, so that corresponding requirements must be placed on the manufacturing process.
  • the object of the present invention is therefore, in particular, to create a simple opening system with a simple sealing system which is not susceptible to faults, and at the same time to increase the quality of the seal and to make it less dependent on fluctuations in the production process without endangering the inexpensive mass production.
  • the object is achieved in particular in that the cap is in one piece in the unopened original state and is connected to the fastening base of the hood unit via a predetermined breaking point and can be opened by breaking open this predetermined breaking point.
  • the cap base is preferably non-detachably connected to the bottle via a securing device.
  • the hood unit according to the invention expediently has a screw base with which it is attached to bottles.
  • this results in a universal usability of the hood unit, since it does not need any specially designed bottle necks for its attachment.
  • this has the advantage over a hood unit that is only fitted over a bead that it is practically impossible to pry the hood unit off the bottle neck as a whole and intact in its original condition.
  • the simple unscrewing of the screw base from the bottle neck is preferably prevented by the screw base being held in a non-detachable manner by a snap lip on a safety ring on the bottle mouth.
  • this embodiment of the invention provides a high level of security against forgery.
  • the hood unit is preferably opened by simply exerting lateral pressure on the cap and breaking it off along the predetermined breaking point. After separating the cap from the cap base, the bottle is preferably closed again by placing the cap on the drop tube. It is particularly useful if the cap is provided on the inside with a pin which fits into the drip mouth of the drop tube and closes it tightly.
  • the cap can advantageously be fixed in particular on the dropper tube that both the dropper tube and the cap each have at least one snap-in position that is matched to the other, preferably inside the cap and on the surface of the dropper tube from at least one bulge or one on top of it There is a coordinated depression, the respective bulge snapping into the matching depression when the cap is replaced on the dropper tube.
  • the bottle is thus opened and closed by simply pulling off or putting on the cap, which makes the closure particularly easy to use.
  • the latching point on the dropper tube is preferably designed as an annular recess and the corresponding latching points of the cap preferably consist of three bulges located at the same distance from one another in the interior of this cap.
  • the user of the medication bottle is relieved of the need to pay attention to a special latching position when the bottle is reclosed.
  • the design of the cap preferably with three bulges located at the same distance from one another, guarantees maximum axial stability of the cap fixation on the dropper tube in the latched position.
  • this viewing distance is produced practically “by itself”, namely in that the cap and the dropper tube are pretensioned in the unopened (original) state.
  • This bias results from the fact that the dropper tube is made of elastically compressible material and is compressed by the still unbroken cap in the direction of the bottle.
  • the axial tube length of the dropper tube measured in the perpendicular direction from the snap-in point to the base level, is greater in this configuration in the open state than the axial cap length, measured in the perpendicular direction from the snap-in point to the cap base level, which is determined by the circumference of the cap at the predetermined breaking point .
  • the hood unit preferably consists of polypropylene or similar materials suitable for injection molding, such as PE, PET, PBT, PA or the like. Because these materials have the advantage that they can be steam-sterilized, which means that the system can be subjected to steam sterilization that is customary in industry.
  • hood unit 1 on the bottle neck 2 of a medication bottle, which has a dropper tube 3 and a cap 4 slipped over it.
  • the cap 4 is connected via the predetermined breaking point 5 to a fastening base 6 secured to the bottle neck 2, which in the exemplary embodiment shown formed as a screw base and is permanently attached to the safety ring 8 on the bottle neck 2 with a snap lip 7.
  • One-piece design here means that, in contrast to known hood units, the cap 4 and the fastening base 6 are not attached to a base base surrounding the bottle mouth, but instead, consisting of a piece of material, are fixed directly on the bottle mouth 2. From the outset, this eliminates the need for a seal between the base of the base and the other base, which simplifies both the safety of use and the manufacturing process.
  • the safety in use is improved in particular because each sealing surface carries the risk of becoming leaky due to manufacturing tolerances or bending due to improper or improper use and thus no longer guaranteeing the necessary sterility and storability of the bottle contents.
  • the simplest way to avoid these problems is to look for a construction in which these problems cannot occur or can only occur to a limited extent from the outset.
  • the exemplary embodiment demonstrates the astonishingly simple solution to make the sealing surfaces in the base area superfluous by continuing the mounting base 6 in one piece into the cap 4.
  • a forgery of the contents of the container d. H. a change in the container content without this being visible through the destruction of the one-piece structure of the hood unit or through other damage to the substance of the hood unit 1 is thus virtually impossible.
  • the invention thus ensures a very high level of security against forgery.
  • the hood unit 1 is opened by simply applying lateral pressure on the cap 4, in that the cap 4 is separated from the fastening base 6 along the predetermined breaking point 5.
  • the predetermined breaking point 5 thus fulfills not only a securing function but also an opening function at the same time. While in the case of an opening mechanism by means of a separating ring which can be pulled off an ear, the ear serving as a handle can break off and the opening mechanism thus fails, the system according to the invention also ensures this reliable and simple way of opening, where you can hardly do anything wrong.
  • the hood unit 1 is suitable for one-handed opening by enclosing the bottle by hand and at the same time pressing the thumb laterally against the cap 4.
  • the cap 4 After the cap 4 has been broken off from the base 6 of the hood unit, the cap 4 can be pulled off (cf. FIG. 2), as a result of which the drip mouth 9 of the dropper tube 3 is released.
  • bulges 12 are provided on the inner wall of the cap 4 at a corresponding height over the inner circumference and engage when the cap 4 is placed on the dropper tube 3 in the recesses 11 of the dropper tube 3.
  • three bulges 12 are provided at the same distance from one another in the exemplary embodiment. The bottle is thus opened and closed by simply pulling off or putting on the cap 4, which makes the closure particularly easy to use.
  • the bulges 12 snap into each Fall into the recess 11 without having to pay attention to a specific rotational orientation of the cap 4 relative to the dropper tube 3.
  • the locking points 11, 12 also ensure that the pin 10 is firmly seated in the drip mouth 9 and closes it tightly.
  • an area of the outer surface of the dropper tube 3 from the drip mouth 9 downward is formed as a downwardly widening, conical mating surface 13 which in the closed state fits on the correspondingly shaped conical mating surface 14 inside the cap 4. With the locking of the locking points 11 u. 12 these fitting surfaces 13 and 14 lie close together and thus additionally ensure a tight closure of the bottle.
  • the dropper tube with its outward flange-like, annular end 15 is pressed firmly onto the bottle mouth 2 by means of the flange-like fastening base 6.
  • the dropper tube 3 is made of rubber-elastic material, it can also adapt well to small unevenness in the bottle mouth and ensure a permanent tight closure of the bottle at the bottle mouth, regardless of whether the cap 4 has broken off or itself is still in its original state on the dropper tube 3.
  • FIG. 3 shows a hood unit 1, which has broken open, so is no longer in its original state, but is closed again.
  • the difference of the hood unit in the state of 1 and in the state of FIG. 3 catches the eye at first glance (although this is not even a colored representation).
  • the cap 4 In the broken but closed state, the cap 4 has a base distance 16 from the mounting base 6, which leads to the fact that the dropper tube 3, clearly colored in the exemplary embodiment, is visible in the now open space.
  • the first use of the bottle is clearly indicated for everyone by a colored stripe between base 6 and cap 4.
  • the predetermined breaking point 5 is under tensile stress, then when the tension is released, the dropping counter tube 3 expands axially and / or the cap 4 contracts , so that in the relaxed state in the axial direction there is a difference in length between the length of the dropper tube 3 and the length of the covering cap, with the consequence of the base spacing 16 already mentioned.
  • the axial tube length L 1 of the dropper tube 3, measured in the perpendicular direction from the snap-in point 11 to the base plane 17, is greater in the open state than the axial cap length L 2, measured in the perpendicular direction from the snap-in point 12 to the cap base plane 18, through the circumference of the cap is set at the predetermined breaking point 5.
  • the first use of the bottle is thus easy, clear and easy to identify.
