Definitions
- the present invention relates to a container assembly according to the preamble of claim 1, comprising a container part and a lid part, said lid part comprising a connection portion for connection to said container part and a lid being pivotably connected to said connection portion.
- the invention further relates to such a lid part.
- Such a container assembly and lid part are known from PCT/NL 2005/000089 .
- a package is disclosed therein for containing both a product and a spoon.
- Subject invention can be used in combination with such a package but it should be noted that it can also be used with other prior art packages.
- Such a container assembly is produced by combining the container part with the lid part. More particular the connection portion of the lid part is adhered to the top side of the container. It is aimed to optimize the assembly of the lid part and container part as much as possible. To that end lid parts should be automatically supplied and manipulated to be brought in position on the container part. Exact positioning of the lid part is essential.
- the invention aims to improve handling of the lid parts in order to more easily assemble lid part and container part.
- Another object of the invention is to improve the handling of the container with the lid part and container part attached to it.
- Yet another object of the invention is to provide the improvements without deteriorating other beneficial properties of the container assembly.
- the invention relates to a container assembly according to claim 1.
- the container assembly is referred to by 1. It comprises a lid part 2 and a container part 3.
- Container part 3 is provided with a bottom 4 and the bottom material is connected to the side walls and defines a circumferential rim 5.
- the container part can be made of cardboard, coated with a synthetic coating layer known in the art for making it suitable for containing food or liquids.
- the container part can also be made of plastic or metal, preferably for holding food or liquids.
- Lid part 2 comprises a connection portion 8, a (living) hinge 6 and a lid 7.
- Lid 7 is pivotably connected to connection portion 8.
- Connection portion 8 comprises a circumferential U-shaped rim 13 to receive the upper edge 12 of the side wall of the container part 3. Fixation of the connection portion 8 to the container wall can be effected through any means known in the art.
- the upper edge 12 of the container part 3 is folded and thus forms a double material layer. In practise, however, this needs not be the case and in most case it is a single layer.
- the top of lid 7 is provided with a circumferential cam.
- the lid has two cam portions 9 having interruptions 10 ( Fig. 4 ) between them.
- the cams are parts of the lid 7 bulging out (i.e., away from connection portion 8). It is also conceivable to provide a rim on top of the lid 7. It may even be conceivable to make the cam (circumferentially) bulging in, i.e. towards connection portion 8. It than in fact forms a groove. In that case rim 5 at the bottom of container part 3 is received within this groove.
- the top of the lid 7 is shaped to partially correspond with the shape of a spoon.
- the shape is indicated by 11 ( fig. 4 , 5 ).
- clamping means fig 5 , nr 29
- the lid is substantially rectangular and shape 11 is position diagonally.
- Interruptions 10 of the cam portions 9 are at the position where it "crosses" shape 11.
- Preferably about 20% of the circumference at the position of cams 9 comprises interruptions 10.
- the lid is further provided with a circumferential rim 14 which in the closed position covers at least the top of the connection portion 8.
- Cooperating locking means 31 are provided to lock the lid relative to the connection portion and tamper evident means 30 can be provided over the locking means 31 to prevent abuse.
- locking means 31 comprise a lip 31 on lid 7 with a cam on its side directed toward the lid 7, and a cam on connecting portion 8. These two cams engage one another the lid 7 is closed and the locking lip 31 is not operated and disengage when the locking lip 31 is operated, allowing a user to open the lid 7.
- the locking lip 31 is tiltably connected to lid 7, and is tiltable around an axis in the main plane of the lid 7 and near the boundary of the lid 7.
- the lip 31 is connected to the lid 7 via a thinned part 26 of the lid (see fig. 6 ).
- the locking lip 31 extends above the main surface 22 of the lid 7, as is the case in the embodiment shown here, it proved (part of) gripping means via which a user can grip the lid 7 for opening it.
- a gripping area 28 is provided at the position of the locking lip 31 .
- it is created by providing a (local) recess 28 in the lid, and by providing cam 9 in such a way that the inner wall 33 of this cam 9 runs on into a wall of recess 28. In this way, a relatively large plane 33 is created onto which a finger or thumb can rest when operating locking lip 31 with another finger/thumb.
- cam 9 has a top 24 which, as already mentioned, extends about 5-7 mm above the surface 22 defined by rim 14, which substantially defines the plane of the lid 7.
- Wall 25 is the outer wall of cam 9. Locking lip 31 does not extend above this cam in order not to compromise the stackability of lid parts and/or container assemblies.
- Tamper evidence means 30 is in this embodiment comprises a lip 30 which is connected to the connecting portion 8 via thin connecting bridges. These bridges are provided near both sides of locking lip 31 of the locking means 31 and near the end of the locking lip 31 of these locking means.
- the connecting bridges need to be broken in order to remove the security lip 30 and to allow a user to tilt locking lip 31 of the locking means 31, and can be formed in a (synthetic material, e.g. PE, PP) moulding process of the lid portion 2.
- a lip which is used which is connected using connecting bridges which can be moulded in one go together with the lip and the rest of the lid portion, the security means can be completely integrated in the side wall.
- the security lip has a part 35 which extends above the locking lip (at this position, the locking lip has a lower part 36), thus allowing easy removal of the security lip 30.
- the height of the security lip 30 and of the locking lip 31 should preferably not extend above edge 24 of cam 9.
- Cams 9 have a substantial height D, e.g. about 5-7 mm. Furthermore, in this embodiment, cams 9 are part of the lid 7 bulging outward with respect to the main plane of the lid (substantially a plane through surface 22 of rim 14). Because of that the cams 9 function as reinforcement ribs adding to the strength of the lid and in this way it is possible to stack a number of container assemblies on top of each other such as is shown for example in fig. 2 in a very stable manner. This effect of providing more rigidity to the lid is increase as a wall of the cam 9 almost extends or goes over into rim 34. This rim 34 of the inside of the lid 7 fits in the inside 23 of inner U-shaped rim 20.
- the inner U-shaped rim 20 has ribs 21 providing rigidity to the rim 20.
- the height of this inner side 23 of inner rim 20 is preferably at least the height of cam 9, i.e. about 5-7 mm.
- Rim 23 of lid 7 extends within the connecting part 8 to such an extend that it leaves enough height of rim 23 free (the already mentioned 5-7 mm) to be able to stably stack lid parts in the way shown in fig. 3 .
- connection po ion 8 at least at the lower end thereof is indicated by B, wherein B is slightly larger than C.
- B is slightly larger than C.
- the spacing between opposite sides of the circumferential rim 5 at the bottom side of container part 3 is indicated by A.
- A is about the same as B allowing for stacking of container assemblies using the combination of the circumferential rim 5 and cam portions 9 of the lid.
- the dimensions A-C are all taken in the same direction. In different directions A-C will have other values but the same principle applies to provide for stable and robust stacking of both the lid parts and the container assemblies in a later stage.
- the spacing between the cam and the circumferential rim, the connection portion respectively is preferably about 0,5 mm.
- the cam portions there are at least three and preferable four or more points of contact between the related circumferential rim and the cam portions providing a stable stacked assembly. Stacks of ten packages or more can be obtained.
- the circumferential shape of the rim 5 of the container part 3 and of the cam 9 on the lid 7 are mutually adapted in such a way that the rim 5 closely fits around the cams 9.
- the diameter B and circumferential shape of rim 23 of the connecting portion is designed in such a way that the circumferential rim 23 of the connecting portion closely fits around cam 9 of lid 7.
- cam portions 9 function both to cooperate with corresponding accommodation in the connection portion 8 and the rim 5 at bottom 4 of the container part, it will be obvious that two sets of cam portions can be provided.
- Lid portion 2 further has a levelling part 27 inside rim 20.
- This part 27 is provided at the edge of rim 34 at a distance from the lower edge of the inner wall of rim 20 to allow stacking of lid portions 2.
- This levelling part 27 allows levelling of the spoon.
- Lid 7 further has a dome-shaped part 32 at its centre part for providing additional rigidity of lid 7.
- the shape 11 indicating and holding a spoon bulges outward with respect to the plane of lid 7.
- This may provide additional rigidity to lid 7.
- the top 24 of cams 9 define the main plane and outside surface of lid 7.
- wall 25 still defines stacking means providing an abutment for the rim 5 of the bottom of container portion 3, together with surface 22 of rim 14.
- the shape of a spoon may be indicated in another way, and clamping means 29 for a spoon may still be present.
- connecting part 8 still has a rim 20 with inner side 23 for providing a first element of the first complementary stacking means.
- the lid has depressions, in this embodiment a circumferential groove which is dimensioned to retain both rim 20 of the lid part 2 when stacking lid parts, and rim 5 when stacking container assemblies 1.
- the groove provides at a groove wall a vertically extending abutment.
- This vertically extending (with respect to the plane of the lid 7) abutment can also be formed by, when radially following the surface of the lid 7 from the outside 22 to the centre, lowering the surface of the lid with respect to surface 22 of rim 14, thus providing an abutment against forces radially outward.
- the vertically extending abutment can also be formed by making the surface of the lid higher after surface 22 of rim 14, thus providing an abutment against forces radially inward.
- the outside of rim 5 abuts the abutment of the lid 7, in the second embodiment, the inside of rim 5 abuts the abutment of the lid 7.
- the abutment of the lid prevents shifting. It is clear that these abutments do not need to be completely circumferential, but in many designs and practical embodiments, they will be.

PCT/NL 2005/000089 - Such a container assembly is produced by combining the container part with the lid part. More particular the connection portion of the lid part is adhered to the top side of the container. It is aimed to optimize the assembly of the lid part and container part as much as possible. To that end lid parts should be automatically supplied and manipulated to be brought in position on the container part. Exact positioning of the lid part is essential.
- The invention aims to improve handling of the lid parts in order to more easily assemble lid part and container part.
- Another object of the invention is to improve the handling of the container with the lid part and container part attached to it.
- Yet another object of the invention is to provide the improvements without deteriorating other beneficial properties of the container assembly.
- This is realized with a container assembly as described in
claim 1. - The invention relates to a container assembly according to
claim 1. - The various aspects discussed in this patent can be combined in order to provide additional advantageous advantages.
- The invention will be further elucidated referring to an preferred embodiment shown in the drawing wherein shown in:
-
Fig. 1 in exploded view a container assembly according to the invention; -
fig. 2 the container assembly according tofig. 1 after assembly; -
fig. 3 a stack of lid parts before assembly with the container part; -
fig. 4 a perspective top and side view of a lid part according to the invention; -
fig. 5 a perspective bottom and side view of the lid part offig. 4 ; -
fig. 6 a cross section offig. 4 , -
fig. 7 the lid part offig. 4 opened, i.e., with the lid hinged open with respect to the connection portion, -
fig. 8 an alternative lid-shape. - In the figures the container assembly is referred to by 1. It comprises a
lid part 2 and acontainer part 3.Container part 3 is provided with abottom 4 and the bottom material is connected to the side walls and defines acircumferential rim 5. The container part can be made of cardboard, coated with a synthetic coating layer known in the art for making it suitable for containing food or liquids. The container part can also be made of plastic or metal, preferably for holding food or liquids. -
Lid part 2 comprises aconnection portion 8, a (living)hinge 6 and alid 7.Lid 7 is pivotably connected toconnection portion 8.Connection portion 8 comprises acircumferential U-shaped rim 13 to receive theupper edge 12 of the side wall of thecontainer part 3. Fixation of theconnection portion 8 to the container wall can be effected through any means known in the art. In these drawings, theupper edge 12 of thecontainer part 3 is folded and thus forms a double material layer. In practise, however, this needs not be the case and in most case it is a single layer. - The top of
lid 7 is provided with a circumferential cam. In the embodiment shown in the drawings the lid has twocam portions 9 having interruptions 10 (Fig. 4 ) between them. In the embodiment shown, the cams are parts of thelid 7 bulging out (i.e., away from connection portion 8). It is also conceivable to provide a rim on top of thelid 7. It may even be conceivable to make the cam (circumferentially) bulging in, i.e. towardsconnection portion 8. It than in fact forms a groove. In thatcase rim 5 at the bottom ofcontainer part 3 is received within this groove. - The top of the
lid 7 is shaped to partially correspond with the shape of a spoon. The shape is indicated by 11 (fig. 4 ,5 ). Inside thelid 7 clamping means (fig 5 , nr 29) are provided to accommodate and hold a spoon having the shape and size ofshape 11 of the spoon (not shown). Fromfig. 4 it is clear that the lid is substantially rectangular andshape 11 is position diagonally.Interruptions 10 of thecam portions 9 are at the position where it "crosses"shape 11. Preferably about 20% of the circumference at the position ofcams 9 comprisesinterruptions 10. - The lid is further provided with a
circumferential rim 14 which in the closed position covers at least the top of theconnection portion 8. Cooperating locking means 31 are provided to lock the lid relative to the connection portion and tamperevident means 30 can be provided over the locking means 31 to prevent abuse. In this embodiment, locking means 31 comprise alip 31 onlid 7 with a cam on its side directed toward thelid 7, and a cam on connectingportion 8. These two cams engage one another thelid 7 is closed and thelocking lip 31 is not operated and disengage when thelocking lip 31 is operated, allowing a user to open thelid 7. In this embodiment, thelocking lip 31 is tiltably connected tolid 7, and is tiltable around an axis in the main plane of thelid 7 and near the boundary of thelid 7. To that end, thelip 31 is connected to thelid 7 via athinned part 26 of the lid (seefig. 6 ). In case thelocking lip 31 extends above themain surface 22 of thelid 7, as is the case in the embodiment shown here, it proved (part of) gripping means via which a user can grip thelid 7 for opening it. - At the position of the locking lip 31 a
gripping area 28 is provided. In this embodiment, it is created by providing a (local)recess 28 in the lid, and by providingcam 9 in such a way that theinner wall 33 of thiscam 9 runs on into a wall ofrecess 28. In this way, a relativelylarge plane 33 is created onto which a finger or thumb can rest when operatinglocking lip 31 with another finger/thumb. - In
fig. 6 it is further indicated thatcam 9 has atop 24 which, as already mentioned, extends about 5-7 mm above thesurface 22 defined byrim 14, which substantially defines the plane of thelid 7.Wall 25 is the outer wall ofcam 9. Lockinglip 31 does not extend above this cam in order not to compromise the stackability of lid parts and/or container assemblies. - Tamper evidence means 30 is in this embodiment comprises a
lip 30 which is connected to the connectingportion 8 via thin connecting bridges. These bridges are provided near both sides of lockinglip 31 of the locking means 31 and near the end of the lockinglip 31 of these locking means. The connecting bridges need to be broken in order to remove thesecurity lip 30 and to allow a user to tilt lockinglip 31 of the locking means 31, and can be formed in a (synthetic material, e.g. PE, PP) moulding process of thelid portion 2. In the embodiment shown for instance infig. 4 , it is clear that because a lip is used which is connected using connecting bridges which can be moulded in one go together with the lip and the rest of the lid portion, the security means can be completely integrated in the side wall. In particular, the security lip has apart 35 which extends above the locking lip (at this position, the locking lip has a lower part 36), thus allowing easy removal of thesecurity lip 30. The height of thesecurity lip 30 and of the lockinglip 31 should preferably not extend aboveedge 24 ofcam 9. -
Cams 9 have a substantial height D, e.g. about 5-7 mm. Furthermore, in this embodiment,cams 9 are part of thelid 7 bulging outward with respect to the main plane of the lid (substantially a plane throughsurface 22 of rim 14). Because of that thecams 9 function as reinforcement ribs adding to the strength of the lid and in this way it is possible to stack a number of container assemblies on top of each other such as is shown for example infig. 2 in a very stable manner. This effect of providing more rigidity to the lid is increase as a wall of thecam 9 almost extends or goes over intorim 34. Thisrim 34 of the inside of thelid 7 fits in the inside 23 of innerU-shaped rim 20. The innerU-shaped rim 20 hasribs 21 providing rigidity to therim 20. The height of thisinner side 23 ofinner rim 20 is preferably at least the height ofcam 9, i.e. about 5-7 mm.Rim 23 oflid 7 extends within the connectingpart 8 to such an extend that it leaves enough height ofrim 23 free (the already mentioned 5-7 mm) to be able to stably stack lid parts in the way shown infig. 3 . - The spacing between the outsides or
outer walls 25 of thecam portions 9 is indicated infig. 4 by C. - The internal width of the
connection po ion 8 at least at the lower end thereof is indicated by B, wherein B is slightly larger than C. This allows for stacking of a number of lid parts comprisingconnection portion 8 andlid 7 on top of each other as is shown infig. 3 to obtain a stable stack. Such a stable stack is desirable during automated provision of the lid parts on the container parts during assembly thereof. - In
Fig. 1 , the spacing between opposite sides of thecircumferential rim 5 at the bottom side ofcontainer part 3 is indicated by A. Preferably A is about the same as B allowing for stacking of container assemblies using the combination of thecircumferential rim 5 andcam portions 9 of the lid. It will be understood that the dimensions A-C are all taken in the same direction. In different directions A-C will have other values but the same principle applies to provide for stable and robust stacking of both the lid parts and the container assemblies in a later stage. The spacing between the cam and the circumferential rim, the connection portion respectively is preferably about 0,5 mm. Because of the shape of the cam portions there are at least three and preferable four or more points of contact between the related circumferential rim and the cam portions providing a stable stacked assembly. Stacks of ten packages or more can be obtained. The circumferential shape of therim 5 of thecontainer part 3 and of thecam 9 on thelid 7 are mutually adapted in such a way that therim 5 closely fits around thecams 9. Furthermore, the diameter B and circumferential shape ofrim 23 of the connecting portion is designed in such a way that thecircumferential rim 23 of the connecting portion closely fits aroundcam 9 oflid 7. - Although in this preferred embodiment the
cam portions 9 function both to cooperate with corresponding accommodation in theconnection portion 8 and therim 5 atbottom 4 of the container part, it will be obvious that two sets of cam portions can be provided. -
Lid portion 2 further has a levellingpart 27 insiderim 20. Thispart 27 is provided at the edge ofrim 34 at a distance from the lower edge of the inner wall ofrim 20 to allow stacking oflid portions 2. This levellingpart 27 allows levelling of the spoon. -
Lid 7 further has a dome-shapedpart 32 at its centre part for providing additional rigidity oflid 7. - In the embodiment shows in the drawings, the
shape 11 indicating and holding a spoon bulges outward with respect to the plane oflid 7. This may provide additional rigidity tolid 7. It is, however, also conceivable to let for instance the top 24 ofcams 9 define the main plane and outside surface oflid 7. In that case,wall 25 still defines stacking means providing an abutment for therim 5 of the bottom ofcontainer portion 3, together withsurface 22 ofrim 14. In this case, the shape of a spoon may be indicated in another way, and clamping means 29 for a spoon may still be present. - In another shape of
lid 7, shown infig. 8 , connectingpart 8 still has arim 20 withinner side 23 for providing a first element of the first complementary stacking means. In this embodiment of the lid, however, the lid has depressions, in this embodiment a circumferential groove which is dimensioned to retain both rim 20 of thelid part 2 when stacking lid parts, andrim 5 when stackingcontainer assemblies 1. In fact, the groove provides at a groove wall a vertically extending abutment. This vertically extending (with respect to the plane of the lid 7) abutment can also be formed by, when radially following the surface of thelid 7 from the outside 22 to the centre, lowering the surface of the lid with respect to surface 22 ofrim 14, thus providing an abutment against forces radially outward. The vertically extending abutment can also be formed by making the surface of the lid higher aftersurface 22 ofrim 14, thus providing an abutment against forces radially inward. In the first embodiment, the outside ofrim 5 abuts the abutment of thelid 7, in the second embodiment, the inside ofrim 5 abuts the abutment of thelid 7. In both embodiments, the abutment of the lid prevents shifting. It is clear that these abutments do not need to be completely circumferential, but in many designs and practical embodiments, they will be. - It will also be obvious after the above that further embodiments are within the scope of protection of the appended claims being obvious combinations with prior art techniques and the disclosure of this patent.
