[0001] This invention relates to a liner assembly for a transport container.
[0002] Transport containers are well known for carrying various types of goods from one
location to another, which locations can be some considerable distance apart. Different
considerations apply in relation to the necessary structure of a container for carrying
different types of product. The present invention is particularly concerned with containers
which are used to transport liquid or semi-liquid products such as foodstuffs and
therefore is concerned particularly with containers with which liners are used to
con ain the product within the container. Containers for this use are commonly known
as IBCs (Intermediate Bulk Containers) which can be formed from metallic materials
or moulded plastics as desired or as appropriate. Furthermore, known containers for
this purpose are provided with a discharge outlet aperture in the container through
which an outlet gland of the liner containing the product can project to allow easy
emptying of the container.
[0003] Problems have been known to arise with existing containers and liners for this purpose
inso ar as it is very important that the gland assembly of the liner is able to be
positioned correctly relative to the discharge outlet aperture of the container in
order that the contents of the liner can be allowed out to the fullest extent possible.
Such an exercise is capable of being carried out where the container concerned has
either a dropdown panel forming a part of or the entire side of the container since
it is then easy enough to gain access to the discharge outlet aperture to ensure that
the outlet gland is located correctly for dispensing. However, in other containers
which have no dropdown walls, it can be very difficult for an operative to correctly
insert the liner into the container ensuring the correct location of the gland. This
is because typically these containers for this purpose can be over 1 metre in height
restricting access to the bottom of the container.
[0004] The present invention is designed to overcome this particular problem by providing
a liner assembly which can be inserted into a container, without the need for a dropdown
side, and which ensures in a simple manner that the outlet gland of the liner correctly
locates in the discharge outlet aperture of the container.
[0005] Thus and in accordance with the present invention there is provided a liner assembly
for use with a transport container, the liner assembly comprising a liner having a
outlet gland for co-operation with an outlet aperture of a container and a fill gland
through which contents of a product to be transported can be introduced into the liner,
said liner being mounted on a support sheet of semi-flexible material, said sheet
being adapted to engage the outlet gland of the liner assembly in a fixed position
relative to the sheet, said flexible sheet being substantially the same shape and
dimensions of a bottom surface of the container, wherein when the said liner assembly
is introduced into a container, correct engagement of the outlet gland with the discharge
outlet aperture can be assured.
[0006] With this arrangement, it is possible to fit a liner assembly to a transport container
in such a way that the outlet gland thereof is correctly located in relation to an
outlet aperture of the container.
[0007] Preferably the liner is removably attached by attachment means to the flexible material.
The attachment may take the form of hook and pile fasteners or any other form of attachment
which is suitable or desirable.
[0008] Preferably the flexible support carries an arrangement which is operable to ensure
that the outlet gland is fixed in position relative to the support and also to ensure
full discharge of contents of the liner when delivered. In this respect, the mounting
also includes a discharge ramp which ensures that the outlet gland when connected
is lower than the line bottom surface when full in order to ensure that the entire
product can be discharged.
[0009] According to a second aspect of the present invention, there is provided a transport
container for liquid or semi-liquid products including a liner assembly according
to the first aspect of the invention.
In accordance with a third aspect of the invention there is provided a method of fitting
a liner assembly to a transport container by providing a support member, releasably
attaching the liner to said support member in such a manner that an outlet gland of
the liner is secured in a gland mounting of the support member, placing the liner
assembly so far into the bottom of the container with said outlet gland locating purely
in said container.
[0010] The invention will now be described further with reference to the accompanying drawings,
of which:
Figure 1a is a cross sectional representation of one form of liner assembly in accordance with
the present invention, and
Figure 1b is a cross sectional representation of a container into which a liner assembly is
being fitted;
Figure 2 shows the liner assembly located in a container; and
Figures 3a, 3b and 3c show the steps followed in fitting the liner assembly to the containe. Figures 3a
and 3b show front and cross sectional views respectively of a person lowering the
liner assembly into a container.
Figure 3c shows a front view of a closed container fitted with the liner assembly.
[0011] Referring now to Figures 1a and 1b there is shown a representation of a liner assembly
in accordance with the invention.
[0012] The liner assembly 2 consists of a flexible or semi-flexible support sheet, a support
body 1 to which a liner 2b is removably attached. The liner has a filling gland 3
of conventional type and an outlet mounting 8 attached having an outlet gland 4 through
which it is intended that the contents of the liner can be effected once the liner
has been filled with a suitable product. The outlet mounting 8 has a discharge ramp
12 which ensures the outlet gland, when fitted in the container, is lower than the
liner bottom surface. This enables the entire product to be discharged from the container.
[0013] The support body 1 is at least sufficiently flexible to allow easy installation of
the liner 2b into the container 5 and to allow easy location of the outlet mounting
8 and gland 4 in the outlet aperture of the container into which the liner will be
fitted. The liner itself is formed conventionally from a plastic or thermoplastics
material of any suitable type and maybe folded into a compact form on the support
sheet, for easy handling such that the filling gland 3 lies on top of the sheet 1.
[0014] If desired, the liner may be removably connected to the support body 1 by any suitable
removable attachment, for example by virtue of hook and pile fasteners (not shown).
[0015] The support sheet 1 may also be provided with a handle 7, such as a web strap or
straps, or some other flexible material, at one end thereof, to enable the sheet,
to be fitted into the container by an operator 13, as well as providing means for
easily removing the assembly from the container.
[0016] The support body 1 is dimensioned so as to conform exactly with the internal bottom
dimensions of the container 5 into which it is to be fitted.
[0017] Figure 2 shows the liner assembly mounted in a suitable container ready for filling
through the filling gland 3. The outlet mounting 8 and gland 4 of the assembly co-operates
with the outlet aperture 6, so that the liner contents maybe easily emptied from the
container by operation of the outlet gland from the exterior of the container. As
the liner is filed (not shown) through the filling gland 3, so the liner will take
the form of the confines of the container 5. The handle 7 maybe attached to one or
more brackets 9 located on the interior of the container so that the handle can be
easily obtained by an operator for further arranging or, removal of the liner assembly
2.
[0018] The method by which the liner assembly is fitted into the container is shown in Figures
3 a, b and c.
[0019] According to the diagrams, it can be seen that with the liner 2b removably secured
relative to the support sheet 1 and with an outlet gland 4 mounted in the gland mounting
8 at one end of the support sheet, the outlet gland 4 can be introduced into the interior
of a suitable containers. The outlet gland of the liner is offered up to the outlet
aperture 6 of the container and the support sheet 1 is allowed to drop into the bottom
of the containers. Because the outlet gland 4 of the liner is locked in position by
the gland mounting 8 formed as an integral part of the support sheet, and the support
sheet is of substantially identical dimensions to the bottom of the container 11,
the support sheet falls into the bottom of the container with the outlet gland 4 in
position relative to the outlet aperture 6 of the container and with the filling gland
3 on the top of the liner. The liner can then be unfolded if folded previously, to
fill the bottom of the container. If it is desirable or necessary to remove or adjust
the support sheet and/or the liner, an attachment handle 7 is provided at an opposite
end of the assembly to the outlet gland 4. The operator 13 may thread the ends of
the handle 7 through the two brackets 9 located on an interio wall of the container
so that he or she has greater control in lifting, fitting and removing the sheet and/
or liner assembly within the container. The brackets also provide means for attaching
the handle to the container when the container is closed or sealed.
[0020] Once the assembly is positioned correctly within the container, the liner can then
be filled with any suitable product in liquid or semi-liquid form, by attachment of
an input hose (not shown) to the filling gland 3. Once the liner is full, the filling
hose can be unattached from the filling gland and a top 14 (as in Figure 3c) can be
placed onto the container to close the container off.
[0021] When the container is delivered to its intended destination, the contents of the
container can be simply dispensed by attachment of a suitable dispense hose to the
outlet gland 4 which forms part of the liner assembly. The discharge of the contents
of the liner via the outlet gland is facilitated by the fact that the outlet gland
of the liner is positioned at a location relative to the bottom of the liner therefor
maximising the amount of product which will be discharged from the liner leaving little
or no waste product in the liner which cannot be extracted.
[0022] With this arrangement, it is possible to ensure the correct fitting of the liner
to a container with the outlet gland correctly located relative to an outlet aperture
of the container in a very simple and easy manner.
