It should be understood, however, that it is not intended to limit the invention to the particular forms disclosed but, on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
- Referring to
FIGS. 1 a-c, apaper container assembly 100 according to one embodiment of the present invention is shown. The container assembly includes acontainer 10 and asecond container 110. Thecontainers container 10 to form a container assembly that is releasably lockable. - It is contemplated that other container assemblies may be formed besides those in
FIGS. 1 a-c. For example, container assemblies may be formed, but are not limited to, using plates, bowls, platters, tubs, single-serve and family-size containers, single-serve and family-size ovenware, and combinations thereof. One such combination is a bowl and a plate that forms a container assembly. The remainder of the application generally discusses container and container assemblies with respect to plates although it is recognized by one of ordinary skill in the art that other container assemblies, such as those discussed above, may be formed. - The height and shape of the container assemblies may vary from that shown without departing from the scope of the invention. For example, the container assembly of
FIGS. 1 a-c, as will be discussed, is depicted as being generally circular. It is contemplated that the container assemblies and containers used herein may be other shapes such as rectangular, square, hexagonal, octagonal, other polygonal shapes, or non-polygonal shapes such as ovals. - The container assemblies and containers of the present invention are typically used with respect to food, but may be used in other applications such as to store household goods, medical supplies, cosmetics or other items. Food container assemblies and containers may be used for serving, storing, preparing and/or re-heating the food.
- Referring still to
FIGS. 1 a-c, thepaper container 10 includes acontinuous body portion 12 and acontinuous rim 14 encompassing and projecting laterally outwardly from thebody portion 12. Thebody portion 12 includes a bottom 16 and acontinuous sidewall 18 encompassing and projecting upwardly and outwardly from the bottom 16. It is contemplated that the sidewall may project only upwardly from the bottom 16 or even project upwardly and inwardly from the bottom 16. It is also contemplated that the rim may not be continuous, although it is desirably continuous. - As shown in
FIGS. 1 a,c, therim 14 includes asurface 14 a (upper surface ofcontainer 10 inFIG. 1 a). Therim 14 includes a cohesive 20. Cohesive is defined herein as a material that will adhere to itself. One example of a type of cohesive that may be used is a water-soluble cohesive. One specific example of a cohesive that may be used is Product No. C-2159P85, which is a cohesive available from Ellsworth Adhesives. This particular cohesive will stick to itself at temperatures of from about 20 to about 400° F. - The use of a cohesive negates the need for an external latching mechanism. This is shown, for example, in the
container assembly 100 ofFIGS. 1 a-c. As will be discussed below in connection withFIGS. 5 a-c, 6 a-c, the use of a cohesive may, however, assist a mechanical locking feature created from the container itself. - It is contemplated that other cohesives may be used. For example, it is contemplated that a non-water soluble cohesive may be used. Non-water soluble cohesives, however, may have disadvantages such as (a) gaining FDA approval in applications involving food, and (b) possible reactions with the paper containers themselves.
- The cohesives of the present invention generally have a pull strength of greater than about 0.5 lb. and, typically, have a pull strength of greater than 1.0 lb.
- The cohesive 20 is shown in
FIG. 1 a as being continuously applied around and in the general shape of therim surface 14 a. It is contemplated that the cohesive may be applied to the entire surface of the rim rather than a portion shown in, for example,FIG. 1 a. According to another embodiment, the cohesive is applied to substantial portions of the rim surface. The cohesive may also be applied intermittently around the rim such as in a pattern. - The cohesive 20 may be applied to the
rim 14 by a variety of methods. For example, the cohesive may be sprayed onto the rim. The spraying may be performed in patterns to efficiently use the cohesive, while still providing a desired holding strength. According to another method, the cohesive may be printed onto the rim. Non-limiting printing techniques that may be used include silk screening, flexo printing, and electrostatic screen printing. Any application method may be used for applying the cohesive 20 to therim 14 provided that it enables a sufficient amount of cohesive 20 to be applied to achieve the desired holding strength. - Referring still to
FIGS. 1 a-c, thepaper container 110 includes acontinuous body portion 112 and acontinuous rim 114 encompassing and projecting laterally outwardly from thebody portion 118. Thebody portion 112 includes a bottom 116 and acontinuous sidewall 118 encompassing and projecting upwardly and outwardly from the bottom 116. It is contemplated that the sidewall may project only upwardly from the bottom 116 or even project upwardly and inwardly from the bottom 116. It is also contemplated that the rim may not be continuous, although it is desirably continuous. - The
rim 114 includes asurface 114 a (bottom-most surface ofcontainer 110 inFIG. 1 a). Therim 114 includes a cohesive 120 (seeFIG. 1 c). The cohesive may be the same as described above in connection with cohesive 20. Thecohesives cohesives - The
paper containers rims cohesives - As shown best in
FIG. 1 c, therim 14 forms at least onerecess 30 therein. Similarly, therim 114 forms at least onerecess 130 therein. Therecess 30 includes the cohesive 20, while therecess 130 includes the cohesive 120. By usingrecesses paper containers rims cohesives rims FIG. 1 c shows the attachedpaper containers rims - According to another embodiment, a container assembly may include rims in which each rim forms a plurality of recesses. For example, referring to
FIG. 2 , arim 44 encompasses and projects laterally outwardly from a body portion (e.g., body portion 12). Therim 44 forms a plurality ofrecesses 46 a,b in which each of the recesses contains a respective one of cohesives 50 a,b. Therim 44 is pressed together with a rim 144, which includes a plurality of recesses 146 a,b in which each of the recesses contains a respective one of cohesives 150 a,b. Therims 44, 144 function in a similar manner as rims 14, 114 described above. It is contemplated that the number of recesses and the dimensions of the recesses may vary from that shown inFIG. 2 . - According to a further embodiment, a container assembly may include rims in which each rim forms a plurality of ripples. For example, referring to
FIG. 3 , arim 64 encompasses and projects laterally outwardly from a body portion (e.g., body portion 12). Therim 64 forms a plurality of ripples 66 a-c projecting generally upwardly therefrom with respective spaces 68 a,b being formed between adjacent ones of the plurality of ripples 66 a-c. Each of the spaces 68 a,b contains a respective cohesive 70 a,b. Therim 64 is pressed together with arim 164, which forms a plurality of ripples 166 a-c projecting generally upwardly therefrom withrespective spaces 168 a,b being formed between adjacent ones of the plurality of ripples 166 a-c. Each of thespaces 168 a,b contains a respective cohesive 170 a,b. - The containers that contain the
rims rims FIG. 3 . - According to a further embodiment, a container assembly may include rims in which each rim has a surface that is generally planar. For example, referring to
FIG. 4 , arim 74 encompasses and projects laterally outwardly from a body portion (e.g., body portion 12).
