Definitions
- the present invention broadly relates to produce containers, particularly but not limited to those having a lid and receptacle with an engaging mechanism that facilitates interlocking of the lid with the receptacle.
- Produce containers are typically piled up and placed in a crate or the like for storage and transportation purposes.
- Those that are currently available in the marketplace have a configuration that would only allow a limited amount of containers, which are typically nested into one another, to be stacked in a pile which in turn is fitted into the crate or the like.
- a larger number of containers to be packed in the crate or the like in order to save space and costs.
- existing produce containers have locking formations which enable interlocking of the lid with the receptacle upon closing of the lid.
- Such containers have a shortcoming that engagement between existing locking formations provided on the lid and the receptacle is quite rough rendering the produce containers susceptible to deformation.
- a produce container including:
- a receptacle which defines a mouth circumscribed by a rim; the rim having a first bearing surface being substantially parallel to a base of the receptacle, a first outer wall portion being folded back on and substantially perpendicular to the base of the receptacle, and one or more first locking formations carried on the first outer wall portion; and a lid associated with the receptacle to close off the mouth, the lid being circumscribed by a skirt, the skirt having a second bearing surface being substantially parallel to the base of the receptacle when the lid is in its closed position, a first inner wall portion being substantially perpendicular to the base of the receptacle when the lid is in its closed position, and one or more second locking formations carried on the first inner wall portion of the lid, each of the second locking formations being complementary to one of the one or more first locking formations;
- the rim includes one or more chamfered portions located above the first locking formation, each of the one or more chamfered portions being inclined to the first bearing surface and the first outer wall portion.
- the first bearing surface is substantially horizontal. More preferably, the first outer wall portion is substantially vertical. Even more preferably, each of the one or more chamfered portions is outwardly and upwardly facing with an upper edge adjoined to the first bearing surface and a lower edge adjoined to the first outer wall portion. As such, each of the one or more chamfered portions eases an otherwise sharp edge where the first bearing surface and the first outer wall portion meet.
- each of the one or more chamfered portions includes a length of flat chamfer in the middle with a lark's tongue finish at both of its ends.
- the chamfer ends short of a piece in a gradual upward curve. More preferably, the length of flat chamfer is in registry with the first locking formation.

Abstract
Description
- This application claims priority to Australian Application No. 2018250515, filed Oct. 19, 2018, which is incorporated herein by reference to the extent permitted by law.
- The present invention broadly relates to produce containers, particularly but not limited to those having a lid and receptacle with an engaging mechanism that facilitates interlocking of the lid with the receptacle.
- Produce containers are typically piled up and placed in a crate or the like for storage and transportation purposes. Those that are currently available in the marketplace have a configuration that would only allow a limited amount of containers, which are typically nested into one another, to be stacked in a pile which in turn is fitted into the crate or the like. Thus there is a need for a larger number of containers to be packed in the crate or the like in order to save space and costs.
- Also, existing produce containers have locking formations which enable interlocking of the lid with the receptacle upon closing of the lid. Such containers have a shortcoming that engagement between existing locking formations provided on the lid and the receptacle is quite rough rendering the produce containers susceptible to deformation.
- It is an object of the present invention to provide a produce container which may meet the above need, or which may overcome or ameliorate the above shortcoming, or which will at least provide a useful alternative.
- According to one aspect of the present invention, there is provided a produce container including:
- a receptacle which defines a mouth circumscribed by a rim; the rim having a first bearing surface being substantially parallel to a base of the receptacle, a first outer wall portion being folded back on and substantially perpendicular to the base of the receptacle, and one or more first locking formations carried on the first outer wall portion; and a lid associated with the receptacle to close off the mouth, the lid being circumscribed by a skirt, the skirt having a second bearing surface being substantially parallel to the base of the receptacle when the lid is in its closed position, a first inner wall portion being substantially perpendicular to the base of the receptacle when the lid is in its closed position, and one or more second locking formations carried on the first inner wall portion of the lid, each of the second locking formations being complementary to one of the one or more first locking formations;
- wherein the rim includes one or more chamfered portions located above the first locking formation, each of the one or more chamfered portions being inclined to the first bearing surface and the first outer wall portion.
- Preferably, the first bearing surface is substantially horizontal. More preferably, the first outer wall portion is substantially vertical. Even more preferably, each of the one or more chamfered portions is outwardly and upwardly facing with an upper edge adjoined to the first bearing surface and a lower edge adjoined to the first outer wall portion. As such, each of the one or more chamfered portions eases an otherwise sharp edge where the first bearing surface and the first outer wall portion meet.
- In a preferred embodiment, each of the one or more chamfered portions includes a length of flat chamfer in the middle with a lark's tongue finish at both of its ends. As such, the chamfer ends short of a piece in a gradual upward curve. More preferably, the length of flat chamfer is in registry with the first locking formation.
- In an alternative embodiment, each of the one or more chamfered portions is a continuous flat chamfer running along a selected or the entire length of the rim.
- Preferably, each of the one or more first locking formations includes a recess. Each recess is preferred to have a slanting upper portion. More preferably, each of the one or more second locking formations includes a lug being aligned with a corresponding recess. Even more preferably, the lug includes a first tapered plane adapted to engage the corresponding inclined chamfered portion of the rim as the lid comes into contact with the mouth of the receptacle. The first tapered plane is preferred to slope from the first bearing surface towards the first outer wall portion.
- Most preferably, the first tapered plane of the lug is complementary to the corresponding inclined chamfered portion so as to facilitate effortless and imperceptible moving of the lug over and beyond the lower edge of the corresponding chamfered portion into engagement with the recess where the lug is received, as the lid closes on the mouth of the receptacle. Most preferably, the effortless and imperceptible moving of the lug over and beyond the lower edge of the corresponding chamfered portion is assisted by the flexibility of the material of which the produce container is made.
- Preferably, the lug includes a second tapered plane adapted to engage a slanting upper portion which forms part of the recess.
- In a preferred embodiment, the produce container includes four pairs of locking formations, each pair comprising the first and second locking formations. Preferably, two pairs of the locking formations are provided along the front of the produce container. More preferably, one pair of the locking formations is provided on each of the lateral sides of the produce container.
- Preferably, the first inner wall portion of the skirt is adapted to overlie and interact with the first outer wall portion of the rim to retain the lid on the receptacle when the lid is in its closed position.
- Preferably, the lid includes a shoulder bounded by the skirt. More preferably, the skirt is located outwardly of the shoulder against which the first bearing surface of the rim of the receptacle bears when the lid is in its closed position.
- The foregoing discussion broadly outlines certain goals and features of the invention to enable a better understanding of the detailed description that follows and to instill a better appreciation of the inventor's contribution to the art. Before any particular embodiment or aspect thereof is explained in detail, it must be made clear that the following details of construction and illustrations of inventive concepts are mere examples of the many possible manifestations of the invention.

- Referring to
FIGS. 1 and 2 , aproduce container 10 is shown which has alid 12 and areceptacle 14. Thereceptacle 14 has four walls defining amouth 24 circumscribed by arim 26. Therim 26 has a first bearingsurface 28 being substantially parallel to abase 30 of thereceptacle 14. Therim 26 also has a firstouter wall portion 32 which is folded back onto therim 26 itself. The firstouter wall portion 32 is substantially perpendicular to thebase 30 of thereceptacle 14. Furthermore, therim 26 has four first locking formations being in the form of recesses carried on the firstouter wall portion 32. Two of the fourrecesses 34 & 36 are provided in a section of the firstouter wall portion 32 that runs along the front of theproduce container 10. The remaining tworecesses 38 & 40 are provided in two respective side sections of the first outwall portion 32. Each side section is located at the two lateral sides of theproduce container 10, respectively. Each of therecesses FIG. 6 for example). - Referring to
FIG. 4 , thelid 12 is provided to close off themouth 24 of thereceptacle 14. Thelid 12 is circumscribed by askirt 42. Theskirt 42 has asecond bearing surface 44 which is substantially parallel to thebase 30 of thereceptacle 14 when thelid 12 is in its closed position. Thelid 12 has a firstinner wall portion 46 which is substantially perpendicular to thebase 30 of thereceptacle 14 when thelid 12 is in its closed position. Thelid 12 also has ashoulder 48 bounded by theskirt 42. Theskirt 42 is arranged outwardly of theshoulder 48 which defines asurface 50 against which thefirst bearing surface 28 of therim 26 of thereceptacle 14 bears when thelid 12 is in its closed position. Theskirt 42 is folded back onto itself to define a secondouter wall portion 52 from which afirst flange 54 extends. In the present embodiment, theskirt 42 has four second locking formations in the form oflugs inner wall portion 46 of thelid 12. Each of thelugs recesses - As best shown in
FIGS. 4 and 4 a, therim 26 has a chamferedportion recesses portion first bearing surface 28 and the firstouter wall portion 32. In this embodiment, thefirst bearing surface 28 is substantially horizontal being substantially perpendicular to the substantially vertical firstouter wall portion 32. All of the chamferedportions portion 60 will be discussed in detail. As best shown inFIG. 4a , the chamferedportion 60 is outwardly and upwardly facing with anupper edge 62 adjoined to thefirst bearing surface 28 and alower edge 65 adjoined to the firstouter wall portion 32. As such, the chamferedportion 60 eases an otherwise sharp edge where thefirst bearing surface 28 and the firstouter wall portion 32 meet. The chamferedportion 60 has a length offlat chamfer 64 in the middle with a lark's tongue finish at both of itsends 66 & 68. As such, the length offlat chamfer 64 ends short of a piece in a gradual upward curve. The length offlat chamfer 64 is in registry with therecess 34. - As best shown in
FIG. 4 , eachlug corresponding recess lugs FIGS. 6 and 7 , thelug 58 has a taperedplane 69 which is adapted to engage a corresponding inclined chamferedportion 60 of therim 26 as thelid 12 comes into contact with themouth 24 of thereceptacle 14. The taperedplane 69 is configured to slope from thefirst bearing surface 28 towards the firstouter wall portion 32. The taperedplane 69 of thelug 58 is complementary to the corresponding inclined chamferedportion 60 so as to facilitate relatively effortless and imperceptible moving of thelug 58 over and beyond thelower edge 65 of the corresponding chamferedportion 60 into engagement with therecess 34 where thelug 58 is ultimately received, as thelid 12 closes on themouth 24 of thereceptacle 14. It should be noted that the effortless and imperceptible moving of thelug 58 over and beyond thelower edge 65 of the corresponding chamferedportion 60 may be assisted by the flexible nature of the material of which theproduce container 10 is made. Also, it will be appreciated that as thelid 12 is fully closed with all fourlugs recesses second bearing surface 44 of the secondouter wall portion 52 of thelid 12 bears against a land 74 (seeFIGS. 4 and 4A ) of astep 76 provided on asecond flange 78 being spaced from thefirst bearing surface 28. As best shown inFIGS. 4, 6 and 7 , thelug 50 also has a second taperedplane 70 which is adapted to engage a complementary slantingupper portion 72 which forms part of therecess 34 when thelid 12 is in a closed position. - As described above, the
produce container 10 has four pairs of locking formations, 34 & 58, 36 & 56, 38 & 62 and 40 & 60, each pair comprising the first and second locking formations. Theproduce container 10 has a recess formation 80 which is formed in therim 26 of thereceptacle 14. The recess formation 80 is flanked by the two pairs of the lockingformations 34 & 58 and 36 & 56 which are provided along the front of theproduce container 10. The other two pairs of the lockingformations 38 & 62 and 40 & 60 are provided on the respective lateral sides of theproduce container 10. - As best shown in
FIG. 5 , when thelid 12 is in its closed position, the firstinner wall portion 46 of theskirt 42 is adapted to overlie and interact with the firstouter wall portion 52 of therim 26 to retain thelid 12 on thereceptacle 14. - It should be noted that it is common practice to nest a plurality of produce containers into one another so as to enable them to be piled up and fitted into a crate or the like for compact storage or transportation. Referring to
FIGS. 8 and 9 , for example, when aproduce container 10 is nested intoproduce container 10A, the chamferedportion 60A facilitates a drop or advancement of theproduce container 10 into theproduce container 10A by a certain length as indicated by A-A (seeFIG. 9 ). This drop or advancement was enabled by the slantingchamfer 64 and would not be achievable with a normal n-shaped rim. When a large number of produce containers, for example, 10, 10A, 10B . . . etc. are piled up, the saved lengths A-A, B-B . . . etc. add up allowing fitting of a larger number of produce containers in each crate or the like which leads to substantial cost savings. - Now that a preferred embodiment of the present invention has been described in some detail, it will be apparent to a skilled person in the art that the produce container of the present invention may offer at least the following advantages:
- 1. it facilitates relatively effortless and imperceptible closing of the lid on the receptacle and easy and smooth engagement of the lugs with the recesses; and
- 2. it enables fitting of a larger amount of produce containers into a crate or the like for storage and transportation which results in substantial cost savings.
- Those skilled in the art will appreciate that the invention described herein is susceptible to variations and modifications other than those specifically described. For instance, each chamfered portion may be a continuous flat chamfer running along a selected or the entire length of the
rim 26. All such variations and modifications are to be considered within the scope and spirit of the present invention the nature of which is to be determined from the foregoing description. - Therefore, the following claims are intended to define the scope of protection to be afforded to the inventor. Those claims shall be deemed to include equivalent constructions insofar as they do not depart from the spirit and scope of the invention. It must be further noted that a plurality of the following claims may express, or be interpreted to express, certain elements as means for performing a specific function, at times without the recital of structure or material. As the law demands, these claims shall be construed to cover not only the corresponding structure and material expressly described in this specification but also all equivalents thereof.
