Tamper-evident sealing for seals of nozzle-shaped ports of a
container
Abstract
The invention concerns the tamper-evident sealing (10) for seals
(12, 14) of at least two nozzle-shaped ports (16, 18) of a
container (20) such as infusion solution pouches. In order to
achieve a secure sealing, while being easy to apply and with minor
material use, it is intended that the tamper-evident sealing (10)
is implemented as a ribbon-shaped shrink wrap that joins the ends
(28, 30) of the ports (16, 18) and encompasses the seals (12,
14).

Description
[0001] The invention concerns a tamper-evident sealing for seals of
at least two nozzle-shaped ports of a container.
[0002] A tamper-evident sealing for seals of nozzle-shaped ports of
a container based on prior art is characterized in that the entire
container, including the nozzle-shaped ports with their seals, is
sealed into plastic foil wrapping. The wrapping can be subsequently
evacuated. The outer packaging serves on the one hand as a
tamper-evident sealing for the seals of the nozzle-shaped ports and
on the other the outer packaging is intended to reduce the
evaporation of the liquid content, for instance of a container
implemented as an infusion solution pouch.
[0003] Meanwhile, plastics for infusion solution pouches, for
instance made from polypropylene-plastics, are available which
feature almost 100% water tightness, so that a complete outer
packaging does not appear to be stringently necessary and is
associated with high material loss and therefore with high
costs.
[0004] Furthermore tamper-evident sealings for nozzle-type openings
of containers are known, for instance from DE-A-196 22 689, wherein
for every opening of the nozzle-shaped ports a respective
tamper-evident sealing is implemented which, however, are costly
from a construction point of view.
[0005] Based on these considerations the invention has as its
object to further improve a tamper-evident sealing for seals of
nozzle-shaped ports of a container in such a way that it can be
easy to install with little use of material and that it offers a
secure sealing.
[0006] The object is met according to the invention by the fact
that the tamper-evident sealing is implemented as a ribbon-shaped
shrink wrap that joins the ends of the ports and encompasses the
seals.
[0007] By means of the ribbon-shaped shrink wrap a secure sealing
of the seals of the nozzle-shaped ports is achieved with little use
of material.
[0008] According to a particularly preferred embodiment the
ribbon-shaped shrink wrap is implemented as a shrink down hose
section. By these means the benefit is achieved that, besides minor
material use, a simple application is achieved. To this end shrink
down hose sections are cut off from a shrink down hose roll, then
pulled over the ends of the nozzle-shaped ports that feature the
seals, and subsequently heat treated so that the shrink down hose
sections encompass the seals in a form-fitting manner.
[0009] In order to achieve an easy opening of the tamper-evident
sealing, it is provided, in the longitudinal direction, with a
break-off point such as perforation, which can be easily torn
open.
[0010] Furthermore an optical marking can be applied to facilitate
detection of the perforation in the longitudinal direction.
[0011] Preferably the shrink down hose section is manufactured from
transparent plastic.
[0012] A further preferred embodiment is characterized in that the
nozzle-shaped ports feature equal lengths, wherein the seals
mounted to the ends of the seals rest against one another in the
sealed position and interlock with one another. An unintentional
opening of the seals is thereby impossible.
[0013] Furthermore the seals are provided, on their edges, with
longitudinally running grooves about which the shrink down hose
section conforms, so that to this extent the shrink down hose
section is also a rotational safeguard.
[0014] A further preferred embodiment is characterized in that the
nozzle-shaped ports are implemented as flexible tube endings and
that the seals can be brought in contact toward one another.
[0015] Preferably the seal is implemented as a Luer-Lock seal.
[0016] Additional details, advantages and characteristics of the
invention are specified not only in the claims, from which the
characteristics can be gathered--as such and/or in combination--but
also from the following description of an embodiment example that
can be gleaned from the drawing.
[0017] The only figure presents a tamper-evident sealing 10 for
nozzle-shaped ports 16, 18, each provided with a seal 12, 14, of a
container 20, such as an infusion solution pouch. The container 20
encompasses a flexible container that defines an interior space as
well as upper and lower heat seal or shrink wrap sections 22, 24.
In the upper sealing section 24 an opening 26 is provided for
hanging purposes. In the lower sealing section 22 the nozzle-shaped
ports 16, 18 are located, which preferably are implemented as
flexible hose line.
[0018] The ends 28, 30 of the ports 16, 18 that feature seals 12,
24 are joined with one another by means of tamper-evident sealing
10 that is implemented as a shrink wrap. The shrink wrap 10 is
thereby implemented as a shrink down hose section that is pulled
over the seals 12, 14 and is then heat treated. The shrink down
hose section 10 shrinks as a result of the heat treatment with the
result that a seal is achieved.
[0019] For the easy opening of the tamper-evident sealing 10 it is
intended that a perforation 32 is implemented in the longitudinal
direction along which the tamper-evident sealing 10 can be
exposed.
[0020] The seals 12, 14 are provided with grooves 34, 36 which
interlock in the sealed state so that insofar an unintentional
opening of the seals 12, 14, which preferably are implemented as
Luer-Lock seals, is also prevented.
