Description

The invention relates to a container with a mouth section and a cap which is removably fastened to the container and which have cooperating latching elements, the mouth section having a circumferential projection and furthermore a ring is provided which is circumferentially connected to the lateral surface via a tear-off skin.

The prior art discloses a large number of variants of containers and closures which have a tamper-evident closure and / or a child safety device. These can be arranged differently, e.g. with the help of partially circumferential cams and tear-off tapes. It is often necessary for such a container to seal the contents from the environment in the original, not yet opened state. Furthermore, it may be necessary for a drying agent to be accommodated in the interior of the container in order to protect moisture-sensitive contents.

US 5,398,829 shows an arrangement of an attachment which is plugged onto a container and a closure cap fastened thereon. Before the closing part of the closure cap can be removed, a tear-off tape must be removed, which thus represents a tamper-evident sign. Furthermore, the cap must be placed in a certain position in relation to the attachment in order to be able to remove it. This mechanism is a child lock.

In particular, before the first opening of the closure of a container, it should be tight in order to ensure a longer durability of the elements accommodated in the container, e.g. to enable pharmaceutical tablets, or the like. In this context, it is known to cover the opening of the container with a sealing film. The disadvantage here, however, is that the drying agent has to be introduced into the container in a separate working step before the sealing film is applied. In this case, however, it is not possible to attach the drying agent to the inside of the closure cap of the container, since the sealing film could not have its effect on the contents of the container.

The aim of the invention is therefore to create, in particular, a container which has a tamper-evident closure and which, in the original closed state, is essentially leak-proof against liquid vapor, especially water vapor.

This is achieved according to the invention with a container of the type mentioned at the beginning, in which the tear-off skin is in contact with the first projection. The container accordingly has an opening and a mouth section which extends essentially in a cylindrical shape starting from the opening. On the container, a closure cap which closes the opening in a closed position and can be removed from the opening is provided with an essentially cylindrical outer surface which at least partially surrounds the mouth section in the closed position. The lateral surface preferably completely surrounds the mouth section in the circumferential direction. First cooperating latching elements are provided on an inner surface of the outer surface of the closure cap and on an outer surface of the mouth section, so that the closure cap and container are reliably connected to one another in the closed position, and the closure cap is e.g. when turning from the intended use position of the container, in which the opening is arranged in the vertical direction above, into an inverted position, with the container opening below, the closure cap is held on the container. These first cooperating latching elements can represent, for example, a mechanism for child safety or part of a mechanism for child safety of the closure cap of the container.

Below the first cooperating locking elements, a first circumferential projection is provided in the mouth section of the container. Furthermore, a ring is provided, the upper edge of which is connected to the circumferential surface all round via a tear-off skin. The ring is in particular designed in such a way that the cap cannot be removed from the container without opening or breaking the ring; i.e. the ring is designed in particular as a tamper-evident closure. According to the invention, the tear-off skin is in contact with the first projection in a closed position. The tear-off skin is thus at the same time a sealing skin which, in contact with the first projection, represents a sealing effect against the ingress of moisture into the container. In order to fulfill this purpose particularly well, the tear-off skin is preferably in circumferential contact with the first projection. The first projection can, for example, also serve as protection against manipulation of the closure cap of the container with a tool. In particular, it can prevent a pointed object from being driven under the outer surface of the cover.

In a preferred embodiment of the container it is provided that the container has a second preferably circumferential projection and the ring has a projection on its inside, the two projections being designed as second latching elements and being in a latching connection with one another. Since the ring is connected to the closure cap via the tear-off skin, these second latching elements can prevent removal and / or rotation of the closure cap as long as the tear-off skin is intact. One or both of the projections are preferably circumferential and are in a snap connection with one another in such a way that axial movement with respect to the essentially cylindrical mouth section is prevented. This locking connection can also have a sealing effect and / or an additional seal can be provided between the second locking elements. Furthermore, it can preferably be provided that the ring itself projects below the second projection of the container in the closed state.

In the closed position of the closure cap, the second latching elements are preferably connected under a tensile force which acts essentially in the longitudinal direction of the container. In this way, the tear-off skin is under tension, so that the tear-off skin is pressed against the first projection, which improves the seal between the tear-off skin and the projection.

In a preferred embodiment, the ring has a predetermined breaking point. The ring can thus serve in particular as a tamper-evident closure, which can be torn open at the predetermined breaking point and subsequently separated from the closure cap by tearing the tear-off skin. The predetermined breaking point is preferably designed as a material thinner. Thus the / 24

Ring also serve as a seal, since it is all-round tight. Furthermore, the ring preferably has a grip element. This is shaped in such a way that tension on it breaks the ring at the predetermined breaking point and tears the tear-off skin, so that the ring is separated from the closure cap. The grip element is preferably in the vicinity of the predetermined breaking point. Furthermore, it preferably has a label and / or a symbol, for example an arrow, which indicates the direction in which to pull in order to separate the ring from the closure cap.

In a further preferred embodiment, the first cooperating latching elements are designed on the mouth section as an outwardly projecting snap bead and on the lateral surface as an inwardly projecting snap bead.

For a reliable latching connection between the latching elements, it is provided in an advantageous embodiment that the snap bead essentially runs around the container in the mouth section apart from an opening section.

It is also advantageous if the snap bead is divided into at least one holding bead and one opening bead on the lateral surface, and the snap bead is interrupted between these two beads, the opening bead being smaller than the opening section. In this way, when the opening bead is aligned with the opening portion by rotating the closure cap, the opening bead can be moved through the opening portion in a pull in the direction of the opening of the container. The child-securing features of the closure cap are thus achieved in that, before it is possible to remove it from the container by pulling in the direction of the opening, a further action step, namely the alignment of the opening bead on the opening section, is required.

In a preferred embodiment, the holding bead extends essentially over half or a fraction less than half of the circumference of the lateral surface. This half is also preferably located approximately opposite the opening bead. The holding bead preferably has one or more interruptions, the one interruption at / 24 being located, for example, in the middle of the holding bead. Such an arrangement makes it easier to remove the ring when it has been rotated into the corresponding position, since the pulling of the opening bead through the opening section is not hindered by the holding bead, and consequently an elastic deformation of the closure cap allows the holding bead to be pulled over the pull outward protruding bulge of the mouth area.

The container advantageously has an indicator which indicates the position of the opening section on the mouth section side. There are a large number of possible embodiments of this indicator, for example it can be in the form of an engraving, as a bulge, as knurling in sections and / or as a label. The extension of the indicator can correspond approximately to that of the opening section and / or be aligned with it in the radial direction. Furthermore advantageously, the closure cap has an opening tab on an outer surface which is essentially aligned with the opening bead in the radial direction. Alignment of the opening bead on the opening section is facilitated by a combination of the features of the indicator and the opening tab, which, however, can also be implemented independently of one another.

The opening tab can be designed, for example, as a ramp, the extent of which in the radial direction can correspond approximately to the extent of the opening bead. The side of the lower height of the ramp is preferably that which is closer to the lower edge of the closure cap. The opening tab is particularly preferably located directly above the lower edge of the closure cap. All of these embodiments also facilitate removal of the closure cap because, by pulling / pushing the opening flap when the opening bead is aligned with the opening section, the opening bead can be pulled through the opening section and / or the closure cap is elastically deformed in such a way that the holding bead is deformed over the protruding bulge of the mouth area can be pulled.

It is also advantageous if the closure cap on the / 24

Containers in the closed position facing side has a holder that can serve, for example, to hold a desiccant. As a result, the desiccant can already be attached to or in the cap before the cap is placed on the container. A separate work step for introducing the desiccant into the container is therefore not necessary. After the closure cap has been applied with the tear-off skin of the (tamper-evident) ring which produces a seal to the container which is essentially sealed against liquid vapor, it is thus possible in a particularly simple manner to create a sealed container which is essentially sealed and at the same time has a desiccant.

The holder is particularly preferably designed as a holder for a desiccant tablet. The desiccant tablet particularly preferably has a silica gel or a desiccant based on molecular sieves. With the desiccant, i.a. the shelf life of the contents of the container can be extended.

It is advantageous if the holder for holding a desiccant tablet is cylindrical and has a preferably circumferential holding element into which the desiccant tablet can be received. The production process is thus facilitated since the desiccant tablet can simply be pushed into the holder after the closure cap has been produced and the desiccant tablet is held by the preferably circumferential holding element in the form of a hook-shaped locking element.

In order to simplify handling, in particular twisting, of the closure cap, it is advantageous if the outer surface of the outer surface of the closure cap has knurling. The knurling can encompass part of the outer surface of the closure cap or extend around it, at a part of the height of the closure cap or over the entire height of the closure cap. Instead of knurling, a large number of other design deviations can also be provided, which simplify the handling of the closure cap. In particular, the knurling can be designed as a grooved or serrated profile, the grooves / serrations advantageously being parallel to an axial / 24

Run in the direction of the lateral surface.

In order to improve the sealing of the contents of the container from the environment and / or also to enable a seal after the ring has been torn off, the inner surface of the outer surface of the closure cap can advantageously have a substantially circumferential sealing cam and the mouth section can have a sealing surface, the sealing cam and the Are in contact with the sealing surface.

In order to allow the corresponding rigidity and / or flexibility, it is advantageous if the closure cap and the ring are injection molded from one part and thus have the same material and / or the closure cap and / or the ring is made of a softer plastic, in particular a plastic with a have a lower Shore hardness, for example a lower Shore A hardness or Shore D hardness, than the container. The cap and / or the ring preferably consist of polyethylene and / or an aromatic and / or aliphatic copolyester, for example ECOFlex® or ECOVia® from BASF SE. The container also preferably consists of polyethylene (PE), polyethylene terephthalate (PET), polyethylene furanoate (PEF) and / or polyactide (PLA), particularly preferably polypropylene (PP) and / or high density polyethylene (HDPE). Furthermore, it is advantageous if the tear-off skin is thinner than 0.8 mm, particularly preferably between 0.1 and 0.5 mm thick.

Advantageously, the closure cap and the ring are suitable for being pushed onto the container in one production step and this causes a preload between the container and the closure cap, the ring and the tear-off skin. This can be achieved, for example, in that some or all of the projections, parts or all of the first latching elements, the snap beads of the mouth section and / or the outer surface and / or the sealing cam are designed in the form of a ramp in the push-on direction. The bias serves in particular to produce or to strengthen the sealing effect.

The invention described here is particularly suitable for the storage of medicaments, but should not be restricted to this area of use.

1 and 2 show an embodiment of the container 1 with a closure cap 3 fastened thereon and a ring 5 connected to the closure cap. The container 1 is designed here as a cylinder. On its mouth section 10, which is at least partially covered here, cf. e.g. Fig. 3, the cap 3 and the ring 5 sit on. The closure cap 3 has a lateral surface 30. The upper edge 50 of the ring 5 is connected to the circumferential surface 30 all round via a tear-off skin 4. The lateral surface 30 has a knurling 31 and an opening tab 32. The ring 5 has a predetermined breaking point 52 and in the vicinity thereof a grip element 51 which also has a marking in the form of an arrow which indicates the preferred direction of pull. A predetermined breaking point 52 is designed as a material taper 53.

3, 4 and 5 show an embodiment of the container 1 with the mouth portion 10 and an opening 9. In the mouth portion 10 are the mouth portion-side part of first locking elements 17, which are designed here as a snap bead 11 having an opening portion 12, a first circumferential projection 13, a sealing surface 14 above the snap bead 11 and a second circumferential projection 15. Furthermore, an indicator 16 indicates the position of the opening section 12.

6 and 7 show the closure cap 3 and the ring 5 from a frontal view, the outer surface 30 of the closure cap 3 being connected to the upper edge 50 of the ring 5 via a tear-off skin 7. The opening flap 32, the handle element 51, the predetermined breaking point 52, which is designed as a material taper 53, and the knurling 31 can also be seen.

The closure cap 3 and the ring 5 are shown obliquely from below in FIGS. 8 and 9 and in section through the plane B in FIG. 10 (cf.

Fig. 6) shown. Compared to the figures already described, it can also be seen here that the closure cap has first locking elements on the lateral surface side as an inwardly projecting / 24

Snap bead 34 are formed, which is divided into an opening bead 35 and a holding bead 36. It can be seen that the holding bead 36 is larger than the opening bead 35 and extends approximately over half the circumference of the lateral surface 30, which is opposite the opening bead 35, see. also FIG. 12, the retaining bead 36 having an interruption 37. It can also be seen that the closure cap 3 has a holder 38 on its side 4 facing the container 1 in the closed position, for example for a desiccant tablet. Furthermore, the closure cap 3 has a sealing cam 39 which is formed above the first latching elements 33. Furthermore, the ring has on its inside a projection 54, which is in a latching connection with the second preferably peripheral projection 15 of the container in the closed state before the ring 5 is torn off.

11 and 12 show the closure cap 3, the ring 5, not shown, having been torn off. In particular, the surface-side first locking elements 33 can be seen, which are designed as an inwardly projecting snap bead 34, which consists of an opening bead 35 and a retaining bead 36. The holding bead 36 is larger than the opening bead 35 and extends approximately over half of the circumference of the lateral surface 30, which is opposite the opening bead 35. The holding bead 36 has an interruption 37.

The closure cap 3 has the opening tab 32 and the container 1 has the indicator 16. In FIG. 13, the closure cap 3 is in a position relative to the container 1 in which the closure cap 3 cannot be removed from the container 1. 14, the closure cap 3 is located relative to the container 1, however, in a position in which the opening tab 32 is aligned with the indicator 16 and the closure cap 3 can thus be removed from the container 1.

15 shows an embodiment of the container 1 with the closure cap 3 and ring 5 in a section along the plane A / 24 (cf. FIG. 1). The container has the snap bead 11 with the interruption 37, the first projection 13, the second projection 15, the indicator 16, the sealing surface 14 and a holder 38. In this embodiment, the essentially cylindrical holder 38 has a holding element 40 in the form of a circumferential hook-shaped latching element. A desiccant in tablet form can thus simply be inserted into the holder 38, in which it is then reliably secured via the holding element 40.

The closure cap 3 has a lateral surface 30 with a sealing cam 39, which rests on the sealing surface 14. There is preferably a preload from which the sealing cam 39 is drawn onto the sealing surface 14, the projection 54 on the inside of the ring 5 against the second projection 15 of the container and / or the tear-off skin 7, which is designed as a sealing skin, onto the first projection 13 become.

The exemplary embodiments shown in the figures and explained in connection with these serve to explain the invention and are not restrictive thereof.
