Definitions
- Containers and caps adapted for holding content for long terms need to meet certain requirements in order to provide their content with the required long-term conditions.
- the container and cap need to be adapted to prevent, as much as possible entrance of air, humidity and oxygen into it.
- the permeable part of such container and cap is the interface of its cap or cover with the container.
- the container Once the container has been opened for temporary use and re-closed, its content need to be protected for a second period of time, and possibly need to ensure that a second set of requirements relating to, for example, amount of humidity, oxygen, etc. entering or existing in the container after re- closing, will be kept below defined levels during that second period of time.
- the second period of time may last, typically, for at least several months.
- 6,986,807 to Brunk and 4,146,277 to Santoro disclose a cap of a bottle which comprises a desiccant material enclosed within the cap of the bottle and further enclosed by a porous barrier.
- the efficiency of the desiccant material disposed and used according to this solution is diminished because the desiccant is exposed to the humidity trapped in the container from the time it was first sealed and during the first, longer storage term, before first use. During this long period of exposure to the humidity inside the container the absorption efficiency of the desiccant material is diminished.
- Some other solutions utilize large desiccant packet enclosed inside the cap and protruding into the space of the container, beyond the line of the neck of the container. Still other solutions place the desiccant as part of the wall of the container.
- Solutions known in the art suffer of one or more disadvantages such as exposing and exhausting the internal desiccant packet to the humidity inside the container even before first use; provision of desiccant packets into the content of the container after first opening, which may be dangerous to very young or elderly users who may erroneously swallow desiccant packet instead of a pill; and use of large desiccant packet in the container cap, which protrudes into the container space and permits only a lip seal between cap and container, thus preventing before - use, long-term covering of the container by an hermetic disposable seal and a temper evident member, and preventing the sealing of the cap and container by a soft material at the interface.
- a desiccant cap for a container comprising a case comprising first enclosure part defining a first space; a second enclosure part defining a second space, a desiccant case wholly encased within said first space, a first sealing layer and a second sealing layer, wherein said second sealing layer is attached onto the opening of said first enclosure part and completely closing said first space and said desiccant case in said first space, wherein said second sealing layer comprising one or more passages through it to allow passage of at least one of air, gas and humidity through it and wherein said first sealing layer is attached to said second sealing layer on its face facing away from said first space, said first sealing layer is adapted to prevent passage of humidity through it.
- first space having a first diameter and a first depth
- second space having a second diameter and a second depth, said second diameter is bigger than said first diameter
- desiccant cap further comprising shoulders formed between said first and said second space enclosures, said shoulders defining a partitioning line between said first and said second enclosure spaces.
- the first sealing layer comprising adhering means disposed over the outer perimeter of said first sealing layer on its face facing away from said first space, said adhering means is adapted to adhere said first sealing layer to the opening of said container.
