The present invention relates to stacking containers for products and, in particular, to containers that are adapted to be attached to one or more of similar containers, a lid, and a handle.
To save space and facilitate transportation, containers for certain products may be configured to stack one on top of another. If the product is susceptible to drying out, the containers may be configured to engage each other to define a product cavity that is at least partly airtight.
The present invention is of particular significance in the context of containers for ink pads that store ink, and that application of the present invention will be described herein in detail. However, the present invention has broader application to products other than ink pads, and the scope of the present invention should be determined by the claims appended hereto and not the following detailed description of the invention.
Ink pads are typically compressible, absorbent members impregnated with ink. Bringing an ink pad into contact with a destination surface and applying slight pressure causes ink to be transferred from the ink pad to the destination surface. The destination surface may be a sheet of material on which an image is directly formed or may be an ink stamp or the like that transfers the ink to the sheet of material on which an image is to be formed.
Ink pads are typically mounted on a base member to facilitate handling of the ink pad. The base typically comprises a substantially planar mounting surface to which the ink pad is adhered. In many cases, a cover member is detachably attached to the base member to form a container assembly defining a product cavity sized and dimensioned to surround the ink pad on the base member. When attached to the base member, the cover member inhibits movement of air between the product cavity and the surrounding environment. When the cover member is removed from the base member, the base member can be gripped to facilitate manipulation of the ink pad.
It has long been recognized that the stacking of container assemblies can be useful. For example, as mentioned above, ink pads store ink; when the ink is used to form an image, it is often desirable to use a plurality (two or more) of colors of ink. Stacking container assemblies facilitate the packaging, marketing, storing, and use of a plurality of ink pads, where each of the plurality of container assemblies contains a different color or combination of colors of ink.
A conventional container assembly can be configured such that the cover member of one container assembly engages the base member of another container assembly. A plurality of such container assemblies may be attached together to form a stack. This type of container stack will be referred to as a base/cover stack.
In a base/cover stack, the cover members of all container assemblies (the connected container assemblies) except for one (the exposed container assembly) are connected to the base member of an adjacent container assembly. The cover member of the exposed container assembly is not connected to an adjacent container assembly.
To use the ink pad contained by the exposed container assembly in a base/cover stack, the cover member is simply removed from the base member. The ink pad may then be used in a conventional manner. To use a selected one of the connected container assemblies, the container assembly or assemblies connected to the cover member of the selected container assembly is/are removed. The selected container assembly is now an exposed container assembly. The cover member of the selected container assembly may then be removed from the base member of the selected container assembly, and the ink pad contained therein may be used in a conventional manner.
With its cover member removed, any exposed container assembly may remain connected to at least one other container assembly of the base/cover stack during use, in which case any connected container assembly or assemblies in the stack can be gripped as a handle. Alternatively, the selected container assembly may be detached from the stack and used in a conventional manner. In any case, a base/cover stack can be reconfigured with any container assembly forming the exposed container assembly. Further, any one or more of the container assemblies in the stack can be removed from one end of the stack and attached to the opposite end of the stack.
To reduce the packaging materials used to form a stack of ink pad containers, the base members can be configured to engage either each other or a cover member. This type of container stack will be referred to as a base/base stack. In a base/base stack, the base members of all container assemblies (the connected container assemblies) except for one (the exposed container assembly) are connected to the base member of an adjacent container assembly. The base member of the exposed container assembly is connected to a cover member. A base/base stack thus can be configured to use only a single cover member.
To use the ink pad contained by the exposed container assembly in a base/base stack, the cover member is simply removed from the base member. The ink pad may then be used in a conventional manner. To use a selected one of the intermediate container assemblies, the container assembly or assemblies connected to the selected container assembly is/are removed. The ink pad of the selected container assembly is now exposed and can be used conventionally.
With the cover member removed, any exposed container assembly may remain connected to at least one other container assembly of the base/cover stack during use, in which case any connected container assembly or assemblies in the stack can be gripped as a handle. Alternatively, the selected container assembly may be detached from the stack and used in a conventional manner. In any case, a base/base stack can be reconfigured with any base member of the stack being considered the exposed container assembly, in which case the cover member forms a part of that exposed container assembly. As with a base/cover stack, any one or more of the container assemblies in a base/base stack can be removed from one end of the stack and attached to the opposite end of the stack.
When a container assembly is used to contain an ink pad, a stylus member can be detachably attached to a base member to facilitate manipulation of the ink pad attached to that base member.
The present invention relates to improved container assemblies that can be combined to form a base/cover stack or a base/stack, with or without a stylus member.
The present invention may be embodied as A container system for containing a plurality of ink pads including a cover and a plurality of bases. The cover defines a cover mounting portion. Each base defines a support surface, a first base mounting portion, and a second base mounting portion. Each of the support surfaces is adapted to support at least one of the ink pads. The cover mounting portion is capable of engaging any one of the first base mounting portions to detachably attach the cover to the plurality of bases. The first base mounting portions are capable of engaging the second base mounting portions to detachably attach at least one of the bases to at least another of the bases. The container system operates in a stack mode and in a single mode. In the stack mode, the cover is detachably attached to one of the plurality of bases, and the one of the plurality of bases to which the cover is detachably attached is detachably attached to another of the plurality of bases. In the single mode, the cover is detachably attached to one of the plurality of bases and the plurality of bases are detached from each other.
The present invention may also be embodied as a method of containing a plurality of ink pads comprising the following steps. A cover defining a cover mounting portion is provided. A plurality of bases are provided, where each base defines a support surface, a first base mounting portion, and a second base mounting portion. The cover mounting portion is configured such that the cover mounting projection is capable of engaging the first base mounting portions to detachably attach the cover to one of the plurality of bases. The first base mounting portions are configured such that the first base mounting portions are capable of engaging the second base mounting portions to detachably attach at least one of the bases to at least another of the bases. At least one of the ink pads is supported on each of the support surfaces. The container system is operated in a stack mode by detachably attaching the cover to a first one of the plurality of bases to define the cover chamber, where the at least one ink pad supported by the support surface defined by the first one of the plurality of bases is contained within the cover chamber, and detachably attaching the first one of the plurality of bases to a second one of the plurality of bases to define a first base chamber, where the at least one ink pad supported by the support surface defined by the second one of the plurality of bases is contained within the first base chamber. The container system is operated in a single mode in which the cover is detachably attached to one of the plurality of bases and the plurality of bases are detached from each other.
Referring initially to
In the single mode 20a, the container system 20 comprises a single base 22 and a cover 24. The cover 24 is detachably attached to the base 22 to define a cover chamber 30 when the container system 20 is in the single mode 20a. The container system 20 facilitates storage of a single ink pad 28 in the single mode 20a. Detaching the cover 24 from the base 22 allows the ink pad 28 to be used in a conventional manner.
In the stack mode 20b, the container system 20 comprises a plurality (two or more) of bases 22 and a cover 24. As with the single mode 20a, the cover 24 is detachably attached to the base 22 to define a cover chamber 30 when the container system 20 is in the stack mode 20b. In addition, at least one of the plurality of bases 22 is detachably attached to at least one other of the plurality bases 22 to define at least one base chamber 32. The container system 20 facilitates the storage of a plurality of ink pads 28 in the stack mode 20b. Detaching the cover 24 from one of the bases 22 or any of the bases 22 from bases 22 adjacent thereto allows any of the ink pads 28 attached to the bases 22 to be used in a conventional manner.
In the stylus mode 20c, the container system 20 comprises one or more bases 22 and the stylus 26. In the stylus mode 20c, the stylus 26 is detachably attached to a single base 22 or a plurality of bases 22 to allow the ink pad 28 attached to one of the bases to be used in a conventional manner. Accordingly, the container system 20 facilitates the use of one or more ink pads 28 when configured in the stylus mode 20c.
Given the foregoing, the details of construction and operation of the example container system 20 will now be described in further detail.
The base 22 comprises a support wall 40, a first wall 42, and a second wall 44. The example support wall 40 is substantially planar and defines a support surface 40a and an interior surface 40b. In particular, the first and second walls 42 and 44 extend in opposite directions along the perimeter of the support wall 40.
The first wall 42 and the support surface 40a define a support cavity 46. The support cavity 46 is relatively shallow in a depth dimension to receive the ink pad 28 such that an inking surface 28a of the ink pad 28 extends beyond the first wall 42. However, the example ink pad 28 is slightly smaller than the base 22 in lateral dimensions so that the ink pad 28 may be adhered to the support surface 40a substantially within the support cavity 46. The second wall 44 and the interior surface 40b define an interior cavity 48. The dimensions of the interior cavity 48 are determined as will be described in further detail below.
As shown in
In some situations, the points 40e and 40f facilitate the application of a small amount of ink to a small target surface using the inking surface 28a. In other situations, the entire inking surface 28a may be brought into contact with a target surface in a conventional manner to transfer a relatively large amount of ink to a larger target surface. While the pointed oval shape of the example base 22 is functionally and aesthetically desirable, other shapes having a different desired combination of functional and aesthetic features may be used instead of a pointed oval.

Each mounting portion 92 comprises a mounting edge 94 defined by a first surface 96 and a second surface 98. The mounting edge 94 corresponds at least in part to the shape of the example base 22. In particular, the mounting edge 94 is sized and dimensioned to fit within the interior cavity 48 defined by the second wall 44. The example mounting edge 94 corresponds only partly to the shape of the base 22, being in the shape of an oval with the ends cut off.
The mounting notches 50 and 52 and various mounting projections 60, 62, 64, 66, 84, and 86 have a generally similar cross-sectional area. The mounting notches 50 and 52 can thus receive the projections 60 and 62 as shown in
Additionally, the mounting edge 94 can be displaced beyond the mounting projections 64 and 66 into a locking position in which the projections 64 and 66 interfere with the mounting edge 94 to form an interference fit between the base member 22 and the stylus 26 that positively locks these components together.
In particular, the first edge 96 is slanted to facilitate the pressing of the mounting portion 90 beyond the mounting projections 64 and 66 and into the locking portion 68 of the interior cavity 48. Although the mounting projections 64 and 66 interfere with movement of the mounting edge 94 to prevent the mounting portion 90 from being inadvertently withdrawn from the cavity locking portion 68, the mounting portion 90 can be removed from the locking portion 68 by the deliberate application of manual force on the stylus 26 away from the base member 22. The second slanted surfaces 98 facilitate the removal of the mounting portion 90 from the locking portion 68.
Referring now to
In the single mode 120a, the container system 120 comprises a single base 122 and a cover 124. The cover 124 is detachably attached to the base 122 to define a cover chamber 130 when the container system 120 is in the single mode 120a. The container system 120 facilitates storage of a single ink pad 126 in the single mode 120a. Detaching the cover 124 from the base 122 allows the ink pad 126 to be used in a conventional manner.
In the first stack mode 120b, the container system 120 comprises a plurality of bases 122 and a plurality of covers 124. Each cover 124 is detachably attached to one of the base 122 to define at least one interior chamber 132. In addition, at least one of the plurality of bases 122 is detachably attached to at least one cover members to define at least one outer chamber 134. Detaching the cover 124 from one of the bases 122 or any of the bases 122 from one of the other bases 122 allows any of the ink pads 126 attached to the bases 122 to be used in a conventional manner.
In the second stack mode 120c, the container system 120 comprises a plurality (two or more) of bases 122 and a cover 124. As with the single mode 120, the cover 124 is detachably attached to the base 122 to define a cover chamber 130 when the container system 120 is in the second stack mode 120c. In addition, at least one of the plurality of bases 122 is detachably attached to at least one other of the plurality bases 122 to define at least one base chamber 136. Detaching the cover 124 from one of the bases 122 or any of the bases 122 from bases 122 adjacent thereto allows any of the ink pads 126 attached to the bases 122 to be used in a conventional manner.
In the stylus mode, a stylus is detachably attached to a single base 122 or a plurality of bases 122 to allow the ink pad 126 attached to one of the bases to be used in a conventional manner. Accordingly, the container system 120 facilitates the use of one or more ink pads 126 when configured in the stylus mode.
Given the foregoing, the details of construction and operation of the second example container system 120 will now be described in further detail.
As perhaps best shown in
The first wall 142 and the support surface 140a define a support cavity 146. The support cavity 146 is relatively shallow in a depth dimension to receive the ink pad 126 such that an inking surface 126a of the ink pad 126 extends beyond the first wall 142. However, the example ink pad 126 is slightly smaller than the base 122 in lateral dimensions so that the ink pad 126 may be adhered to the support surface 140a substantially within the support cavity 146. The second wall 144 and the interior surface 140b define an interior cavity 148. As shown in

The sets 150 and 190 of outwardly facing projections 152 and 192 and sets 154 and 174 of inwardly facing projections 156 and 176 are formed on complementary surfaces such that any set 150 and 190 can engage any set 154 and 174. Further, the mounting projections 152, 156, 176, and 192 have a complementary cross-sectional area. The sets 150, 154, 174, and 190 of mounting projections thus allow each base 122 to be connected above and below to another base 122, above and below to one of the covers 124, or above to a cover and below to a base 122. The sets 150, 154, and 174 of mounting projections 152, 156, and 176 thus engage each other to form a connecting system that allows the container system 120 to be configured in the single mode 120a, first stack mode 120b, and/or second stack mode 120c.
In any of these modes 120a, 120b, and 120c, the projections 152 of the first set 150 or fourth set 190 can be arranged in a lock configuration in which the projections 152 or 192 are spaced alternately between the projections 156 or 176 of the second or third sets 154 or 174.
From the foregoing, it should be apparent that the present invention may be embodied in many different combinations and sub-combinations of the elements and steps described above. The scope of the present invention should thus be determined by the following claims and not the foregoing detailed description.
