Definitions

  • the invention relates to a child-resistant closure for containers, in particular for plastic bottles, according to the preamble of patent claim 1.
  • substances are often used which are chemically more or less aggressive and whose ingestion must be prevented, since this can lead to poisoning, chemical burns, etc., or in general to impairments of bodily functions .
  • Such substances are, for example, all types of cleaning agents in powdery or liquid form, washing additives, herbicides, insecticides and much more, which are stored in containers or bottles, in particular those made of plastic. While adults generally control the proper handling of such substances, there is a risk, especially in children, of holding and taking the container contents for something edible. Therefore, children must be protected against unauthorized access to such substances.
  • the object of the present invention is therefore to remedy these disadvantages of containers and bottles, in particular of plastic, and child-resistant closures. It should be presented a solution for the attachment of a child-resistant closure, which allows the most flexible production and use of containers and bottles.
  • Existing container and bottle shapes should be able to be maintained and regardless of the relevant safety regulations, the same containers can be used across borders.
  • the invention provides a child-resistant closure for containers, in particular for plastic bottles, which has a closure cap, on the inner wall of which first engagement means are arranged, which can be brought into rotation by engagement with corresponding second engagement means, which on one side counterpart to the Cap forming Ausgiessstutzen are provided. Furthermore, at least one blocking element is arranged on the closure cap, which cooperates with at least one locking element, which is formed on the pouring spout forming the counterpart to the closure cap.
  • the spout is designed as an adapter. forms, which is equipped with a locking device for captive and permanent mounting on a correspondingly formed container or bottleneck.
  • the design of the spout as an adapter allows flexible manufacture and use of the containers and bottles. Existing container and bottle shapes can be maintained; at most, it may be necessary to provide slight adaptations in the container or bottleneck region, so that the adapter can be mounted captive and inextricably.
  • the adapter makes it possible to use the same containers regardless of the relevant safety regulations across countries. In countries with relevant child safety regulations, the container is sold with the adapter. With less stringent regulations, the same container can be sold without an adapter.
  • the same type of container or bottle can be provided by the invention with or without a child-resistant closure either by mounting the adapter or by selling the container without an adapter and with a conventional closure. For the consumer, the usual appearance of the bottle is retained. The manufacturer can manufacture the bottle type in larger quantities, which has an advantageous effect on the cost.
  • the provision of the child-resistant closure on the adapter also makes it possible to pre-assemble the closure already on the adapter before the adapter is mounted on the container or bottleneck.
  • the locking device on the adapter comprises at least one profiling projecting from an inner wall of the adapter, which can be brought into engagement with a correspondingly formed locking device on the container or bottle neck.
  • the locking device is simple and practical designed to allow a simple and automated installation of the adapter.
  • the adapter is designed for plug-on mounting.
  • an annular projection or a plurality of annularly arranged projections are provided on its inner surface, which project against the inner surface.
  • the projection or projections engage behind a Cutting at the container or bottleneck.
  • the installation of this adapter is particularly simple and only requires an axial plugging or pushing the adapter onto the container or bottleneck until the locking is done automatically.
  • the lock is not solvable and destructible only by a very high force. However, this high expenditure of energy clearly exceeds the physical capabilities of children.
  • the locking of the adapter on the container or bottleneck takes place over the entire circumference of the adapter.
  • a second embodiment of the invention provides that the adapter is designed for a rotating assembly.
  • the adapter is designed for a rotating assembly.
  • from its inner surface protruding first turning engagement cooperate with formed on the container or bottleneck corresponding second rotary engagement means.
  • the locking takes place via locking tabs, which protrude from the inner surface of the adapter and are radially federbar.
  • the locking tabs slide over locking cams on the container or bottle neck.
  • the free ends of the locking tabs run against locking surfaces of the locking cam and prevent further relative rotation of the adapter and the container or bottle neck.
  • the rotary engagement means on the adapter and on the container or bottleneck can be elements of a bayonet closure.
  • the first and second turning engagement means are formed as threaded portions.
  • the adapter has a pouring opening, which can be designed arbitrarily.
  • the adapter is preferably equipped at the Ausgiessöffhung with a sieve-like perforated pouring plate.
  • the engagement means on the closure cap and on the adapter can be designed as elements of a bayonet closure.
  • the first engagement means on the inner wall of the closure cap and the corresponding second engagement means on the outer wall of the adapter are threaded sections.
