Embodiment Construction

[0018] Figure 1~4 The partial assembly shown includes a capsule body 4 having a first end 6 and a second end 8. The capsule body 4 defines a first cavity 14 passing through at least the first wall 10 and a second cavity 16 passing through at least the second wall 12. The partition member 18 is located between the first cavity 14 and the second cavity 16. The partition member may be a common wall that partitions the cavity, or may be used as an additional wall. The capsule body 4 has a peripheral wall 24 at the first end 6 and a flanged flange 32 at the second end in this embodiment. Such as image 3 with Figure 4 As shown, the cavities 14, 16 each have a collapsible, concertina-style wall. Such as Figure 4 As shown, the first cavity 10 has a first blasting nail 20 and the second cavity 12 has a second blasting nail 22.

[0019] Reference now Figure 5-7 , Which shows an example of the stages in manufacturing the dispensing capsule 2. The first cavity 14 is at least partial...

Abstract

A dispensing capsule (2) comprises a capsule body (4) having a first end (6) and a second end (8); a first cavity (14) and a second cavity (16) with a dividing member (18) between them within the capsule body (4), both cavities having an opening at the first end of the capsule body; a peripheral wall (24) at the first end (6) of the capsule body (4); and a flexible seal (30) bonded to the peripheral wall at the first end and to the dividing member so as to seal the contents of the first and second cavities from each other. The seal (30) is bonded less strongly to the dividing member than to the peripheral wall. On an increase of pressure within the two cavities, the bond between the seal (30) and the dividing member (18) will eventually break, permitting the contents of the first cavity (14) to at least partly mix with the contents of the second cavity (16) while the bond between the seal (30) and the peripheral wall (24) remains intact. A burst pin (20, 22) is also disposed within each cavity for breaking the bond between the seal (30) and at least some of the peripheral wall (24).

Description

Technical field [0001] The invention relates to a multi-cavity dispensing capsule, especially for dispensing disinfectant ingredients. Background technique [0002] Many liquid formulations include active ingredients that degrade over time, and these active ingredients limit the shelf life of the product. This is especially true for disinfectants or sterilizers, such as chlorine dioxide, where when the active ingredient is needed, it is formed in situ by mixing two reagents. As in the embodiment disclosed in WO 2005 / 011756. For example, chlorine dioxide can be formed by mixing a solution of monochlorite and an acid. [0003] It is well known to provide a dispensing capsule for positioning the neck of a blood vessel. The capsule has two internal chambers, each containing a reagent. By draining the contents of the chamber into the container to allow the reagent to mix and produce the active ingredient. An example of such a dispensing capsule is described in US 8,839,982. The dis...
