Definitions
- the present invention relates to a container with a child-resistant cup-shaped closure, the opening of the said container being a neck with an external thread in the form of a thread groove for interaction with a radial projection on the internal circular side wall of the cup-shaped closure, whereby the thread has a blocking device in that side of the thread which is in frictional engagement with the projection when the closure is being unscrewed, so that the projection is caught by the blocking device when unscrewing the closure.
- Containers of this kind are also used to safeguard children from the consumption of tablets and like objects which are dangerous to consume.
- a container is known from US patent no. 3 497 096 with a child-resistant cup-shaped closure of the above indicated kind.
- the closure is provided with a single internal projection which normally slides along a helical groove on the neck of the container towards a position where the closure seals the container.
- the projection may optionally pass through a passageway into a locking device or locking groove which in opposite directions of rotation extends a distance away from the passage.
- the thread and the locking groove has the same width everywhere.
- the projection By rotating the closure in opposite directions, the projection will slide backwards and forwards in the locking groove, in that the rotations will inevitably cause it to hit either the one or the opposite end of the locking groove. Since the locking groove extends to each side away from the passageway, it is necessary when unscrewing the closure to know the position of the passageway and the projection on the thread and the closure, respectively, in order for the projection to catch the passageway and have the projection pulled out through it so as for the projection by its engagement with the thread to permit the closure to be unscrewed from the container.
- the known container is thus encumbered with the disadvantage that it is difficult to determine the position of the - passageway of the locking groove in relation to the projection, even if one is familiar with the mode of operation of the locking device. Moreover, it is difficult to screw the closure onto the known container.
- the projection When the closure is screwed onto the thread of the container, the projection will initially move in a frictional engagement with that side of the thread groove which is farthest away from the container until a seal on the end wall of the cup-shaped closure abuts the neck opening of the container. Due to the compression of the seal the frictional engagement of the projection with the said side of the thread groove will be increased in that the seal will thus become sufficiently compressed to seal the contents of the container.
- the thread groove thus has the appearance of a usual thread groove.
- the projection When the closure is unscrewed from the container, the projection will initially continue to be in frictional engagement with that portion of the thread groove which turns away from the container due to the flexibility of the seal which will seek to resume its normal thickness. After turning of the closure the tension stemming from the flexibility of the seal will be relaxed, after which the projection will be in frictional engagement with that side of the thread groove which is closest to the container. The projection will therefore now hit the stop formed by the passage between the expanded and the normal portion of the thread groove and be caught by the stop so that the closure cannot just be twisted past it.
- the closure must therefore be turned a small angle in the opposite direction, after which an axial force can be exerted on the closure in the direction away from the container so that the projection is brought into frictional engagement with the side of the thread groove turning away from the container so as to permit the unscrewing of the closure from the container, at least until the projection has passed the stop.
- the projection When the projection is configured as a stop to catch the projection when this touches the stop, it is prevented that the application of an axially directed force on the closure in the direction away from the container by this position of projection and locking groove will bring the projection in frictional engagement with that side of the thread groove which turns away from the container.
- the container and the child-resistant cup-shaped closure according to the invention devise a far more simple technical effect, because it is possible when unscrewing the closure to feel when the projection meets the stop and is caught by it. Then, the closure must be turned in the opposite direction and be lifted followed by a new turning.
- Fig. 1 shows the whole of a container with the reference numeral 1.
- the container 1 has a neck 2 provided with an external thread 3 which in the form of a thread groove 4 extends helically in a known manner on the outside 5 of the neck 2.
- the thread groove 4 has two sides 4a, 4b, of which the side 4a is the side farthest away from the container 1, and the side 4b is closest to the container 1.
- the thread groove 4 extends round along the outside 5 of the neck 2 of the container 1; if required, however, it may also describe more rounds.
- the neck 2 ends in an end surface 6 which can form the contact face for a seal 14 in a cup-shaped closure as shown in figure 2 and as a whole referred to by the reference numeral 10.
- the outermost portion of the thread groove 4 i.e. that portion which is farthest away from the container 1 and forms the entrance to the thread groove, has a first width a seen in the axial direction of the neck 2, and the innermost portion of the thread groove has a width b which compared to the width a is preferably twice as wide.
- the innermost portion of the thread groove 4 with the width b extends the last distance around the outside 5 of the neck 2.

Abstract
The invention relates to a container (1) with a child-resistant cup-shaped closure (10), the opening of the said container (1) being a neck (2) with an external thread (3) in the form of a thread groove (4) for interaction with a radial projection (15) on the internal circular side wall (11) of the cup-shaped closure (10), whereby the thread (3) has a blocking device in that side (4a) of the thread groove (4) which is in frictional engagement with the projection (15) when the closure (10) is being unscrewed, so that the projection is caught by the blocking device when unscrewing the closure. In order to make it possible for a user who does not know the position of the blocking device in relation to the projection (15) on the inside (12) of the circular wall (11) of the closure (10) to open the container, the width (b) of the thread groove (4) on the last portion of the rotation which is closest to the container (1), is expanded in axial direction in relation to the width (a) of the remaining outermost portion of the thread groove (4) and the passage between the expanded portion and the remaining portion of the thread groove (4) is configured as a stop (7, 8) to catch the projection (15) of the closure (10).
Description
The present invention relates to a container with a child-resistant
cup-shaped closure, the opening of the said container
being a neck with an external thread in the form of
a thread groove for interaction with a radial projection on
the internal circular side wall of the cup-shaped closure,
whereby the thread has a blocking device in that side of
the thread which is in frictional engagement with the projection
when the closure is being unscrewed, so that the
projection is caught by the blocking device when unscrewing
the closure.
In order to prevent children from consuming dangerous
liquids such as acid, paraffin, cleaning materials and like
liquids as are often found in a household and are easily
confused with beverages, it is known to equip such containers
with a child-resistant closure, for instance by way
of a screw cap or a similar device. Containers of this kind
are also used to safeguard children from the consumption of
tablets and like objects which are dangerous to consume.
A container is known from US patent no. 3 497 096 with a
child-resistant cup-shaped closure of the above indicated
kind. The closure is provided with a single internal projection
which normally slides along a helical groove on the
neck of the container towards a position where the closure
seals the container. At a rotary position short of the
sealing position of the closure the projection may optionally
pass through a passageway into a locking device or
locking groove which in opposite directions of rotation
extends a distance away from the passage. The thread and
the locking groove has the same width everywhere. When
screwing on the closure an axial force must be applied on
the closure directed towards the container, whereby the
projection slides into the locking groove when the projection
is opposite the passageway. By rotating the closure in
opposite directions, the projection will slide backwards
and forwards in the locking groove, in that the rotations
will inevitably cause it to hit either the one or the opposite
end of the locking groove. Since the locking groove
extends to each side away from the passageway, it is necessary
when unscrewing the closure to know the position of
the passageway and the projection on the thread and the
closure, respectively, in order for the projection to catch
the passageway and have the projection pulled out through
it so as for the projection by its engagement with the
thread to permit the closure to be unscrewed from the container.
The known container is thus encumbered with the disadvantage
that it is difficult to determine the position of the -
passageway of the locking groove in relation to the projection,
even if one is familiar with the mode of operation of
the locking device. Moreover, it is difficult to screw the
closure onto the known container.
It is the object of the invention based on the known prior
art by a container with a child-resistant cup-shaped closure
to provide such an embodiment of the locking device
that, irrespective whether the position of the locking
groove in relation to the projection is known or not, it
will always be possible to feel this position so that the
closure can be unscrewed. The embodiment must also be such
that the fitting of the closure is performed in the same
simple manner as by a standard screw-cap.
This object is obtained by a container of the kind referred
to in the preamble, which container according to the invention
is
characterised by the features of the second part of claim 1.
When the closure is screwed onto the thread of the container,
the projection will initially move in a frictional engagement
with that side of the thread groove which is
farthest away from the container until a seal on the end
wall of the cup-shaped closure abuts the neck opening of
the container. Due to the compression of the seal the
frictional engagement of the projection with the said side
of the thread groove will be increased in that the seal
will thus become sufficiently compressed to seal the contents
of the container. The thread groove thus has the appearance
of a usual thread groove.
When the closure is unscrewed from the container, the projection
will initially continue to be in frictional engagement
with that portion of the thread groove which turns
away from the container due to the flexibility of the seal
which will seek to resume its normal thickness. After turning
of the closure the tension stemming from the flexibility
of the seal will be relaxed, after which the projection
will be in frictional engagement with that side of the
thread groove which is closest to the container. The projection
will therefore now hit the stop formed by the passage
between the expanded and the normal portion of the
thread groove and be caught by the stop so that the closure
cannot just be twisted past it.
The closure must therefore be turned a small angle in the
opposite direction, after which an axial force can be exerted
on the closure in the direction away from the container
so that the projection is brought into frictional
engagement with the side of the thread groove turning away
from the container so as to permit the unscrewing of the
closure from the container, at least until the projection
has passed the stop.
When the projection is configured as a stop to catch the
projection when this touches the stop, it is prevented that
the application of an axially directed force on the closure
in the direction away from the container by this position
of projection and locking groove will bring the projection
in frictional engagement with that side of the thread
groove which turns away from the container.
As opposed to the known container with a child-resistant
cup-shaped closure where it is very difficult to unscrew
the cap because it is not possible to see from the outside
when the projection enters the locking groove, nor possible
from the outside to determine when the projection is locked
in the locking groove, the container and the child-resistant
cup-shaped closure according to the invention
devise a far more simple technical effect, because it is
possible when unscrewing the closure to feel when the projection
meets the stop and is caught by it. Then, the closure
must be turned in the opposite direction and be lifted
followed by a new turning.
The container with a child-resistant cup-shaped closure
according to the invention will be described in closer detail
in the subsequent detailed portion of the description
with reference to the drawing, in which:
- Fig. 1
- shows a side view of part of a container according to the invention, which container has a neck with an external thread groove for interaction with a cup-shaped closure,
- fig. 2
- shows a side view and a partial section of a cup-shaped closure to be used on the container shown in fig. 1, and
- fig. 3
- shows an enlarged section of the thread groove shown in fig. 1 where an internal projection in the closure shown in fig. 2 is implied as being in engagement with the thread groove in three different positions.
Fig. 1 shows the whole of a container with the reference
numeral 1. The container 1 has a neck 2 provided with an
external thread 3 which in the form of a thread groove 4
extends helically in a known manner on the outside 5 of the
neck 2. The thread groove 4 has two sides 4a, 4b, of which
the side 4a is the side farthest away from the container 1,
and the side 4b is closest to the container 1.
The thread groove 4 extends round along the outside 5 of
the neck 2 of the container 1; if required, however, it may
also describe more rounds. The neck 2 ends in an end surface
6 which can form the contact face for a seal 14 in a
cup-shaped closure as shown in figure 2 and as a whole referred
to by the reference numeral 10.
The outermost portion of the thread groove 4, i.e. that
portion which is farthest away from the container 1 and
forms the entrance to the thread groove, has a first width
a seen in the axial direction of the neck 2, and the innermost
portion of the thread groove has a width b which compared
to the width a is preferably twice as wide. The innermost
portion of the thread groove 4 with the width b
extends the last distance around the outside 5 of the neck
2.
The passage between the narrow and the wide portion of the
thread groove 4 is configured in such a manner that a stop
8 is provided extending a distance below the wall 4b at the
passage to the narrow portion of the thread groove 4 as
shown more clearly in fig. 3. This embodiment of the stop 8
produces a beak 7 which can catch a projection 15 on the
closure 10 as will be explained below.
The closure 10 is cup-shaped and has a circular side wall
11 with an inner surface 12. The closure furthermore has an
end wall 13 which can be provided with the said seal 14.
The inside 12 has a radial projection 15 designed so as to
be able to engage and interact with the thread 3 on the
neck 2 of the container 1 so that the closure can be screwed
onto the container 1.
The projection 15 is preferably made with a circular cross
section and is easy to manufacture.
The projection 15 is thus placed at such a distance from
the end wall 13 of the closure 10 and the seal 14 that the
seal 14 is compressed for the sealing of the contents of
the container 1 when the closure 10 is screwed so tightly
to the neck 2 of the container 1 that the projection 15 has
passed the passage between the narrow and the wide portion
of the thread groove 4.
When the closure 10 is screwed onto the thread 3 of the
container 1 the projection 15 will initially move in a
frictional engagement with that side 4a of the thread
groove 4 which is farthest away from the container 1 until
the seal 14 on the end wall 13 of the cup-shaped closure 10
rests on the neck opening or end surface 6 of the container.
Caused by the compression of the seal 14 the frictional
engagement of the projection 15 with the said side
4a of the thread groove 4 will be increased, thus providing
the required sealing of the contents of the container 1.
This situation is illustrated in figure 3 where the projection
is referred to as 15' in a position where the closure
10 is still not screwed so far down on the thread 3 that
the projection 15 has passed the passage between the narrow
and the wide portion of the thread groove 4.
When the closure 10 is unscrewed from the container 1, the
projection 15 will at first still be in frictional engagement
with the side 4a of the thread groove 4 being farthest
away from the container 1 due to the flexibility of the
seal 14 which seeks to resume its normal thickness. After a
certain rotation of the closure 10 the tension stemming
from the flexibility of the seal 14 will be relaxed, after
which the projection 15 will be in frictional engagement
with the side 4b of the thread groove 4 closest to the container
1. The projection 15 will therefore now hit the stop
8 produced by the passage between the wide and the narrow
portion of the thread groove 4 and be caught there so that
the closure 10 can not just be turned past the stop 8.
The design of the passage is configured complementary to
the circular cross section of the projection 15, whereby a
beak 7 is produced at the said passage or stop 8 which beak
receives the projection 15.
When the passage is configured as a stop 8 with a beak 7 to
receive the projection 15 when it contacts the stop 8, it
is prevented that the application of an axially directed
force on the closure 10 in the direction away from the container
1 by this position of the projection 15 and the
thread groove 4 will bring the projection 15 in frictional
engagement with that side 4a of the thread groove which
turns away from the container.
This situation is illustrated in figure 3 where the projection
15 in the position where it is caught by the stop 8
and the beak 7 is indicated by 15''.
The closure 10 must therefore be turned a small angle in
the opposite direction, after which an axial force implied
by the arrow 16 can be exerted on the closure 10 away from
the container 1 causing the projection 15 to be brought in
frictional engagement with that side 4a of the thread
groove 4 turning away from the container 1, at least until
the projection 15 is brought past the stop 8 for unscrewing
the closure 10 from the container 1.
This situation is illustrated in figure 3 where the projection
is indicated by 15''', where the axially directed
force 16 has not yet been exerted.
In the description above the container 1 with a child-resistant
cup-shaped closure 10 is described with an external
thread 3 on the neck 2 of the container and with a
projection 15 inside the cup-shaped closure. It will, however,
be obvious to one skilled in the art that the thread
in stead may be configured on the inside of the cup-shaped
closure and the projection on the neck of the container. It
is also obvious that the thread can be double or multi-threaded
although the invention is explained by a single-threaded
embodiment.
