Description

CONTAINER WITH A CAP AND ONE

BREAKABLE RING

The invention relates to a container with a Mündungsab section and a removably attached to the container Ver closing cap, the cooperating locking elements, wherein the mouth portion has a circumferential projection and further provided a ring which is peripherally connected via a tear skin with the lateral surface.

The prior art discloses a plurality of variants of containers and closures having a tamper-evident closure and / or a child safety lock. These can be made by different arrangement, e.g. be realized with the help of partially umlau fenden cam and with tear strips. Often it is necessary that such a container in the original, not yet open state, the contents against the environment tet tet. Furthermore, it may be necessary that a desiccant is added to the interior of the loading container to protect moisture-sensitive content.

The US 5,398,829 shows an assembly of an essay, which is placed on a container, and a closure cap attached thereto Ver. Before the closing part of the cap can be removed, a tear strip must be removed, which is thus a tamper-evident sign. Furthermore, the closure cap must be placed opposite the attachment in a certain position in order to remove it. This mechanism is a parental control.

Further childproof lids are known from US 5938054 A, DE 19712364 A1, DE 69202489 T2, EP 0217630 A2 and US 4573599 A.

In particular, before the first opening of the closure of a Behäl age this should be tight to allow a longer shelf life of the elements received in the container, such as pharmaceutical tablets, or the like. In this connection, it is known to cover the opening of the container with a sealing film. The disadvantage here, however, that the Trocknungsmit tel inserted in a separate step in the container. must be brought before the sealing film is applied. An attachment of the drying agent on the inside of the United closure cap of the container in this case, however, is not possible because the sealing foil this could not fulfill its effect on the contents of the container.

The aim of the invention is therefore to provide in particular a container having a tamper-evident closure and wel cher in the original closed state is substantially sealed against liquid vapor, in particular water vapor.

According to the invention, this is achieved with a container of the initially introduced type, in which the tear-off skin is in contact with the first jump ahead. The container therefore has an opening and a mouth portion, which extends in a substantially cylindrical shape, starting from the opening on. On the Behäl ter is in a closed position, the opening close de and removable from the opening cap with a substantially cylindrical surface, which at least partially surrounds the mouth portion in the closed position provided. Preferably, the lateral surface encloses the Mün tion section in the circumferential direction completely. On an inner surface of the lateral surface of the closure cap and on an outer surface of the mouth portion first cooperating Ras telemente are provided so that in the closed position closure cap and container are reliably connected together, and the cap, for. when turning out of the intended use position of the container in which the opening is arranged in ver tical direction at the top, in an inverted Stel ment, with the container opening below, the cap on the loading container is held. These first interacting Rastelemen te, for example, a mechanism for parental control or a part of a mechanism for the child protection of the United closure cap of the container represent.

Below the first cooperating locking elements, a first circumferential projection is provided in Mün training section of the container. Furthermore, a ring is provided, whose upper edge is peripherally connected via a tear-off skin with the lateral surface. The ring is in particular designed such that without opening or breaking the ring the cap can not be removed from the container; ie the ring is designed in particular as a tamper-evident closure. According to the invention, the tear-off skin is in a closed position in contact with the first projection. The tear-off skin is thus at the same time a sealing skin which, in contact with the first projection, provides a sealing effect against entry of moisture into the container. To fulfill this purpose particularly well, the tear-off skin is preferably circumferentially in contact with the first jump ahead. The first projection can serve as example as protection against manipulation of the cap of the container with a tool example. In particular, it can prevent a pointed object from being driven under the outer surface of the lid.

In a preferred embodiment of the container is vorgese hen that the container has a second preferably circumferential projection and the ring on its inside a projection, wherein the two projections are formed as a second locking elements and are in a latching connection with each other. Since the ring is connected via the tear-off skin with the closure cap, these second locking elements can prevent removal and / or rotation of the closure cap, as long as the tear-off skin is intact. Preferably, one or both of the Vorsprün ge are circumferentially and are so miteinan in a latching connection that an axial movement relative to the substantially cylindrical mouth portion is prevented. This snap connection can also fulfill a sealing effect and / or it can be provided an additional seal between the second locking elements. Furthermore, it can preferably be provided that the ring itself protrudes below the second projection of the container in the closed state.

Preferably, in the closed position of the closure cap, the second latching elements are connected under a tensile force acting essentially in the direction of longitudinal extent 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, whereby the seal between the tear-off skin and the projection is improved. In a preferred embodiment, the ring has a predetermined breaking point. Thus, the ring can in particular serve as a tamper-evident closure, which can be torn open at the predetermined breaking point and can subsequently be separated from the closure cap by tearing the tear-off skin. The predetermined breaking point is preferably designed as a material dilution. Thus, the ring can also serve as a seal, since it is circumferentially tight. Wei ters, the ring preferably has a handle member. This is formed so that it breaks the ring at the breaking point and breaks the tear-off skin so that the ring is separated from the closure cap. Preferably, the handle is felement in the vicinity of the predetermined breaking point. Further preferably, it has a label and / or a symbol, such as an arrow, which indicates the direction in which pulled the who should to separate the ring of the cap.

In a further preferred embodiment, the first cooperating locking elements are formed on the mouth portion as outwardly projecting snap bead and on the lateral surface as inwardly projecting snap bead.

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

It is also advantageous if the snap bead on the jacket surface is un divided into at least one retaining bead and an opening bead, and the snap bead between these two Wüls is interrupted, wherein the opening bead is smaller than the opening portion. In this way, when the opening bead is aligned with the opening portion by rotating the cap, the opening bead can be moved through the opening portion in a pull toward the opening of the loading container. The child-resistant features of the closure cap are thus achieved in that, before it is possible to remove them from the container by train in the direction of the opening, also a further action step, namely the alignment of the opening bead on the opening portion needs. In a preferred embodiment, the retaining bead extends substantially over one half or a fraction of less than half of the circumference of the lateral surface. Furthermore, preferably this half is located approximately opposite the opening bead. Preferably, the retaining bead on one or more re interruptions, wherein the interruption is for example in the middle of the retaining bead. By such an arrangement, the removal of the ring, when it has been rotated to the corresponding position, facilitated because the pulling of the Öffnungswulstes is not hindered by the opening portion of the retaining bead, and subsequently allows an elastic deformation of the cap, the retaining bead on the to pull outward projecting Schnaufwulst the mouth area.

Advantageously, the container has an indicator which shows the position of the mouth portion side opening portion. There are a variety of possible embodiments of this indicator, for example, this can be performed in the form of an engraving, as a bulge, as a section knurling and / or as Be writing. The extent of the indicator may be approximately equal to and / or radially aligned with the opening portion. Further advantageously, the closure cap on an outer surface on an opening tab, which is aligned in the radial direction substantially with the Publ nungswulst. By a combination of the features of the in indicator and the opening tab, which, however, may also be carried out independently of each other, an alignment of the Publ tion bead is facilitated at the opening portion.

The opening tab can be designed, for example, as a ramp whose extent in the radial direction can correspond, for example, approximately to the extent of the opening bead. In this case, the side of the lower height of the ramp is preferably that which is closer to the lower edge of the closure cap. Especially before given to the opening tab is located directly above the lower edge of the cap. All of these embodiments also facilitate removal of the closure cap, since the opening bead is interrupted by the opening / closing tab when the opening bead is aligned at the opening portion. section can be pulled and / or the cap of the type is elastically deformed, that the retaining bead can be pulled over the outwardly projecting snap bead of the mouth area.

Furthermore, it is advantageous if the closure cap has a holder on the side facing the container in the closed position, which holder can serve, for example, to receive a desiccant. In this way, the desiccant can already be attached to or in the cap before the cap is placed on the container. A separate operation for introducing the desiccant in the container is thus not required. After application of the closure cap with the tear-off skin of the (originality) ring which produces a substantially liquid-vapor-tight seal from the container, a sealed container which is substantially denser and at the same time having a desiccant can thus be provided in a particularly simple manner.

Particularly preferably, the holder is designed as a holder for a desiccant tablet. Most preferably, the desiccant tablet comprises a silica gel or a molecular sieve-based desiccant. Using the desiccant can u.a. the shelf life of the contents of the container will be extended.

It is advantageous if the holder for holding a dry medium tablet is cylindrical and has a vorzugswei se circumferential holding element into which the desiccant tablet can be added. Thus, the production process is facilitated because the desiccant tablet can easily be pushed into the holder after completion of the closure cap and the desiccant tablet is held due to the preferably circumferential, in the form of a hook-shaped detent element, ausgebil Deten holding element.

In order to simplify the handling, in particular the twisting, the closure cap, it is advantageous if the outer surface of the lateral surface of the closure cap has a knurling.

The knurling may comprise a portion of the lateral surface of the closure cap or around this, on a portion of the height the cap or on the entire height of the cap, run. Instead of knurling, it is also possible to provide a multiplicity of other shape deviations which simplify the handling of the closure cap. In particular, the Rände ment can be designed as a grooved or serrated profile, wherein before geous enough, the grooves / prongs extend parallel to an axial direction of the lateral surface.

In order to improve the sealing of the contents of the container relative to the environment and / or to allow a seal after tearing the Rin ges, advantageously, the inner surface of the lateral surface of the closure cap may have a substantially circumferential sealing cam and the mouth portion has a sealing surface, wherein the sealing cam and the sealing surface are in contact.

In order to ben the appropriate stiffness and / or flexibility ben, it is advantageous if the cap and the ring are molded from one part and thus have the same material and / or the cap and / or the ring wei wei plastic, especially one Plastic with a lower shear Shore hardness, for example, a lower Shore A hardness or Shore D hardness, as the container. Preference, the cap and / or ring made of polyethylene and / or an aromatic and / or aliphatic copolyester, such as ECOFlex® or ECOVia® BASF SE. The container likewise preferably consists of polyethylene (PE), polyethylene terephthalate (PET), polyethylene furanoate (PEF) and / or polyactide (PLA), more preferably polypropylene (PP) and / or high density polyethylene (HDPE). Furthermore, it is advantageous if the tear-off skin is thinner than 0.8 mm, more preferably between 0.1 and 0.5 mm thick.

Advantageously, the cap and the ring are adapted to be pushed in a production step on the container and it is characterized prestressing between the loading container and the cap, the ring and the tear-skin ago. This can for example be achieved by some or all projections, parts or all of the first locking elements, the Schnappwulste the mouth portion and / or the lateral surface and / or the sealing cam in Aufsteckrichtung are executed ramped. The bias is used in particular to produce or enhance the sealing effect.
