Device at a container |
(57) Container consisting of a bottom (1), in principle comprising a pallet, and a cylindrical
member (2) standing thereon and a bag (3) arranged therein. In the bottom there is
a hole (13) sealed by a door (14). When the door (14) is pulled out the bag (3) is
pressed down into the opening and when the door is pushed in the bag will be perforated
after which the contents can be dosed to a desired degree. The cylindrical member
(2) of the container consists of a straight piece of board, which has been perforated
at its ends. Moreover, at the joint there is arranged an interior plate profile provided
with bolts extending through the holes to an outer plate profile and through holes
therein, after which nuts press the two plate profiles against each other.

[0001] This invention relates to the type of container including a bottom which can consist
of e.g. a pallet and a more or less loose tubular member standing thereon and consisting
of board or the like, which tubular member is preferably cylindrical and, even if
it is standing loosely per se on its bottom, is prevented from moving laterally on
this by some type of fixations and is preferably also prevented from tipping relative
to the bottom by some suitable means. Such a container is e.g. de-i scribed in Swedish
application 138/70. This container has above all functioned as a disposable container
as the material is relatively cheap in relation to the costs of return freights. The
cylinder of the container has been made by jointing a piece of board to a cylinder
by nailing or fixing. This forming of the board to a cylinder by nailing or fixing
results in a relatively expensive equipment for the manufacture of the container.
This has the effect, in its turn, that substantially only big manufacturers, who can
justify the investments in equipment for nailing, have been able to use the container.
If this problem could be eliminated the container of the invention might be used considerably
more, and it is desired in this connection, also, that the container might be used
not only as a disposable container but also be easily dismantled to its original components,
i.e. a bottom and a board slab that can be transported in parts or be stored in this
form. This problem is solved in accordance with the invention in such a way that the
board is jointed by means of two plate profiles, one of which has been provided with
welded screws or bolts which extend in jointing through holes in the ends of the board,
after which a corresponding profile provided with holes is placed on the outside of
the container and the profiles are pressed together with nuts and the fixed screws
on the inner plate profile. If desired, the screws can of course be placed on the
inside instead, but by placing the joint straight in front gf a corner of the generally
square bottom plate the outer plate profile or nuts will not be disturbed. The edges
of the plate profiles are preferably adapted so that they engage the board straight
in front of each other. A strong and stable attachment of the board is obtained by
the clamping force exerted by the plate profiles and the fact, of course, that the
holes in the board are connected by means of the screws, and this will ensure an even
distribution of forces at the ends of the board slab so that there will be a minimum
risk of its damage.
[0002] As is easily realized it is simple, by loosening screws and removing the plate profiles,
to reduce the package again to a bottom and a plane disc which can be easily stored
or transported if it is e.g. desired to utilize the containers for transport of bulk
material, e.g. corn.
[0003] For transport of corn, sand, cement and such more finely divided products the above
container has for a long time been combined with a plastic bag placed therein, which
is relatively thin, as it is in principle only a seal of the package. It is therefore
suggested in a further development of the invention, in order to facilitate handling
of this type of container also .in this case, that the bottom of the container, which
generally consists of a pallet or a device similar to a pallet, is proveded with an
opening in which a sliding door is arranged. When the sliding door is drawn out the
plastic bag will sink down into the opening by the weight of the material, and by
pushing in the door it is possible to cut off or break the plastic bag at the opening
so that the container can be easily emptied without more complicated tipping means.
[0004] The invention will be described below more in detail with reference to the illustrative
example shown in the drawings in the form of an exploded view.
[0005] The container shown in the drawing comprises a bottom, which in its entirety has
been designated by 1. On this bottom a cylinder 2 is standing, in which a bag 3 is
arranged, and in the bag the transported or stored material is placed. The cylinder
2 consists of a piece of board which has been bent to a cylinder, and has then been
put together in this position. The two ends of the board have been jointed by providing
these with holes 5 which overlap each other when the board has been rolled up to a
cylinder. Bolts attached to a plate profile 7 extend through these holes, said plate
profile being arranged on the inside of the joint along this. At the outside of the
joint there is arranged another profile 8, which is provided with holes 9 corresponding
to the bolts 6. The profile 8 is thereafter pressed against the inner profile by means
of nuts 10. In addition to assisting in holding the board together to a cylinder the
plate profiles also prevent damage to the ends of the board both from the inside and
from the outside.
[0006] The bottom 1 of the container is in principle a pallet, on the loading plane 11 of
which the cylinder 2 as well as the bag 3 and the contents are resting. In order to
prevent the movement of the cylinder 2 on this plane laterally there is arranged a
guide inside the cylinder in the form of a circular edge 12. around the cylinder.
By giving the flange 12 a sufficient height the cylinder 2 can also be prevented from
tipping laterally relative to the bottom 1. As is apparent from Fig. 1 a hole or an
opening 13 is provided in the loading plane 11. This opening is closed on the underside
by means of a plate door that can be drawn out. This plate door 14 is pointed at its
front end so that it can be drawn out, the bag being pressed down into the hole 13,
after which the bag can be cut to be broken, when the door is pushed in again. When
the door is then opened the material will run out to a desired extent. There is a
guide plate or guide flange 15 on the underside of the door 14, which prevents the
material to be tapped from being thrown out lateral- .ly.
1. A device at a container of the type comprising a bottom and a cylindrical member
of e.g. board, cardboard or the like and placed on the bottom more or less lossely,
characterized in that the cylinder consists of a disc jointed by a clamping means
consisting of an inner. and an outer plate profile, which are pressed against each
other by a number of screw joints distributed along the profiles.
2. The device of claim 1, characterized in that the jointed ends of the board are
provided with holes corresponding to the screw joints so that the screw joints also
extend through the two board ends.
3. The device of any one of the preceding claims, characterized in that the screw
joints comprise bolts attached to the- inner plate profile and cooperating nuts arranged
on the outside of the other plate profile.
4. The device of any one of the preceding claims, characterized in that a plastic
bag is disposed in the container to fill out this and to enclose the stored or transported
material and that the bottom-comprises a recess that is closed by means of a door
which is made so that it can perforate the part of the bag when being pulled out and
then pushed in, said bag being pressed down into the recess by the contents when the
door is pulled out.
5. The device of claim 4, characterized in that the door is provided with a flange
directed obliquely downwards and inwards or an additional plate in order to prevent
material running out through the opening from being thrown out laterally.
