Definitions
- This patent document relates generally to containers, such as those in the configuration of packages and tubs, which may or may not have a lid. Further, the container relates to such containers that are used to store articles, such as food.
- the container with self-aligning lid relates to disposable food containers, which have particular application for containing food that is for sale, such as at a food market.
- These containers are commonly made out of disposable and recyclable materials, such as paper and plastic.
- a container base is provided that houses the food with a lid secured thereto.
- the lid simply snaps to the base to seal the food contents therein.
- the lid can be a separate member or hingedly connected to the base.
- a container with the lid hingedly connected to the base is commonly referred to as a “clamshell” container configuration.
- the food manufacturer or food preparer simply loads the food into the base, hingedly pivots the lid over the base and then pressed downwardly to snap the lid thereon and into communication with the base.
- prior art clamshell container configurations suffer from the disadvantage of the lid frequently not properly aligning with the base prior to closure. This can result in a damaged container that does not close properly, necessitating that the container be discarded, resulting in waste. This is particularly true when these containers are filled and then closed using automated machinery because such automated machinery requires that the lid be near or perfectly aligned as possible with the base prior to closure to ensure a proper friction fit.
- present clamshell containers suffer from many disadvantages in that they have difficulties when automatic machine closures are employed thereby increasing waste and expending additional time.
- a container that is includes a self-aligning lid yet does not necessitate costly changes to the container.
- the container with self-aligning lid preserves the advantages of prior art containers. In addition, it provides new advantages not found in currently available containers and overcomes many disadvantages of such currently available containers.
- the invention is generally directed to the novel and unique container that has a general clamshell configuration.
- the hinge of the container is unique in that it not only provides a hinged connection between the lid and the base of the container for ease of use by the food manufacturer during filling but is also self-aligns with the base of the container assisting closing and sealing.
- the hinge is specially configured to include a pair of conical locating pins that engage a reciprocal pair of tapered slots on the flange of the base.
- the tapered slots may be U-shaped or V-shaped.

- Polyethylene terephthalate (“PETE”) plastic is preferably 0.025 inch Ga.
- the reinforcing ribs 22 are optionally provided in different locations on the container 10 to provide desired additional rigidity at those locations of container 10 . Further, these reinforcing ribs 22 may be provided of any desirable size and shape to make various portions of the container 10 more rigid without increasing the thickness of the material used.
- the container 10 configuration is particularly well-suited for thermoformed containers that are made out of plastic, which may be transparent, translucent or opaque.
- the walls may be of, for example, 10 mil in thickness but may be of any desired thickness and flex.
- the profile of the hinge 16 may be modified so that it may spring in any desired direction to facilitate separation of the lid 14 from the base 12 .
- Thermoforming, using the appropriate tooling (not shown), is so well known in the art that it need not be discussed in detail herein. Suffice it to say that the tooling would be appropriately manufactured to provide the desired base 12 , lid 14 and hinge 16 profiling.
- Containers 10 made out of other materials by other methods can also be achieved using the container with self-aligning lid described herein.
- a new and novel container with a self-aligning lid is provided.
- the unique self-aligning lid greatly assists in aligning the lid with the base before closing pressure is applied to the lid thus ensuring that the lid is optimally located when pressure is later applied to the lid for closure to the base thereby reducing risk of damage to the container or poor closure of the lid to the container.

Abstract
Description
- This patent document claims priority to earlier filed U.S. Provisional Application Ser. No. 62/327,481, filed Apr. 26, 2016, the entire contents of which are incorporated herein by reference.
- This patent document relates generally to containers, such as those in the configuration of packages and tubs, which may or may not have a lid. Further, the container relates to such containers that are used to store articles, such as food.
- It is well known in the art that containers are commonly used to store food, but it should be understood that the invention relates to any type of container for any type of purpose.
- More specifically, the container with self-aligning lid relates to disposable food containers, which have particular application for containing food that is for sale, such as at a food market. These containers are commonly made out of disposable and recyclable materials, such as paper and plastic. As a result, there is a first concern as to the use of material that can be recycled. Also, there is a concern that the packaging container be clear or have a window so the consumer can inspect the food prior to purchase. In view of these needs, a container base is provided that houses the food with a lid secured thereto. Commonly the lid simply snaps to the base to seal the food contents therein. The lid can be a separate member or hingedly connected to the base. A container with the lid hingedly connected to the base is commonly referred to as a “clamshell” container configuration. These container configurations are very well known in the art.
- In use, the food manufacturer or food preparer simply loads the food into the base, hingedly pivots the lid over the base and then pressed downwardly to snap the lid thereon and into communication with the base. However, prior art clamshell container configurations suffer from the disadvantage of the lid frequently not properly aligning with the base prior to closure. This can result in a damaged container that does not close properly, necessitating that the container be discarded, resulting in waste. This is particularly true when these containers are filled and then closed using automated machinery because such automated machinery requires that the lid be near or perfectly aligned as possible with the base prior to closure to ensure a proper friction fit.
- In view of the above, present clamshell containers suffer from many disadvantages in that they have difficulties when automatic machine closures are employed thereby increasing waste and expending additional time. There is a need for a container that is includes a self-aligning lid, yet does not necessitate costly changes to the container. There is further demand for a container that is less expensive and complicated to manufacture than prior art containers. There is yet another need to provide a container that speeds filling of containers.
- The container with self-aligning lid preserves the advantages of prior art containers. In addition, it provides new advantages not found in currently available containers and overcomes many disadvantages of such currently available containers.
- The invention is generally directed to the novel and unique container that has a general clamshell configuration. The hinge of the container is unique in that it not only provides a hinged connection between the lid and the base of the container for ease of use by the food manufacturer during filling but is also self-aligns with the base of the container assisting closing and sealing. To accomplish this, the hinge is specially configured to include a pair of conical locating pins that engage a reciprocal pair of tapered slots on the flange of the base. By way of example, the tapered slots may be U-shaped or V-shaped.
- It is therefore an object to provide a container with a self-aligning lid that is easy to fill with food.
- Another object of the invention is to provide a container that has a lid that is self-aligning when it is hingedly closed over the base in preparation for downward pressure for closure, either by automated machinery or by hand.
- Another object of the container described herein is to provide a container with a self-aligning lid that can be manufactured using common thermoforming equipment.
- The novel features which are characteristic are set forth in the appended claims. However, the invention's preferred embodiments, together with further objects and attendant advantages, will be best understood by reference to the following detailed description taken in connection with the accompanying drawings in which:
-
FIG. 1 is a top perspective view of the container in an open condition; -
FIG. 2 is a top perspective view of the container in a closed condition; -
FIG. 3 is a close-up perspective view of the hinge of the container shown in the inset ofFIG. 1 ; -
FIG. 4 is a side elevation view with the lid in a half-closed condition, showing the pins starting to engage the tapered slot for lid alignment; -
FIG. 5 is a side view showing the peripheral engage of the lid resting, and not fully engaged, with the top flange of the container; -
FIG. 6 is a side elevation view of the container in a closed condition; -
FIG. 7 is a partial cross-sectional view, top view showing pins engaging the tapered slots on the contained; -
FIG. 8 is a side cross-section view through line 8-8 ofFIG. 2 , showing the pin seated in the tapered slot and the peripheral edge of the lid fully seated in the flange of the container; -
FIG. 9 is a close-up view of the hinge of the container shown in the inset ofFIG. 8 . - Turning first to
FIGS. 1 and 2 , thecontainer 10 is shown to be of a general clamshell configuration with abase 12 and alid 14 hingedly connected thereto viahinge 16. Thehinge 16 may be a breakaway or tear-away hinge (such as with the use of perforations, not shown) or permanently attached to thebase 12 orlid 14. For ease of discussion thecontainer 10 is shown inFIG. 1 is an open condition. Thecontainer 10 is also shown in a closed condition inFIG. 2 . Thebase 10 includes a top edge 17 with a peripheral bead orflange 18. As is shown inFIGS. 2, 4-6 , thelid 14 may be pivoted about thehinge 16 to a closed position over thebase 12. Theperipheral edge 20 of thelid 14 frictionally snaps into the top edge 17 of thebase 12 and secured by the peripheral bead orflange 18, as is well known in the art. Such frictional engagement of thelid 14 to thebase 12 requires a downward pressure on the top of thelid 14 toward thebase 12. This can be carried out by hand or by automated machinery, which is well known in the art. - Referring now to
FIG. 3 , a close-up view of thecontainer 10 and theunique hinge 16 construction is shown. Thehinge 16 is connected at its top portion to thelid 14 and extends laterally away from thelid 14 and then down forming a middle portion (best seen inFIGS. 7 and 8 ). The middle portion of thehinge 16 is connected to aflange 18 emanating outwardly from the top edge 17 of thebase 12. Reinforcingrib members 22 may be formed on the middle portion of thehinge 16, which add rigidity and structural support to thehinge 16, allowing the use of thinner plastic. Additional reinforcingrib members 22 may be formed on the bottom flange portion of thebase 12. - Protruding inwardly from the
hinge 16 is a pair of locatingpins 24, which are preferably conical in shape but could be of any configuration. Opposite thepins 24 and formed in theflange 18 are correspondingslots 26, as best seen inFIG. 3 , which are preferably tapered but may be of any configuration. By way of example, thetapered slots 26 may be U-shaped or V-shaped. As shown inFIGS. 4, 5, and 6 , thetapered slots 26 are configured to receive and guide the tips of thepins 24 on thehinge 16 as thelid 14 is transitioned from an opened condition to a closed condition. As thepins 24 enter the wider opening of the taperedslot 26, thepins 24 are guided within the taperedslot 26. As a consequence, thelid 14 is centered in the XY plane over thebody 12 of thecontainer 10 as thelid 14 descends to the base 12 in the Z direction (best seen inFIG. 5 ). As shown inFIGS. 7-9 , the length of the conical pins, space the hinge and, consequently, thelid 14 in the X direction over thebase 12. Theslots 26 further align thepins 24 and, consequently, thelid 14 in the Y direction over thebase 12. As a result, thelid 14 is accurately aligned over the base 12 in preparation for being finally pressed downwardly toward thebase 12 by applying pressure in the Z direction, thereby snapping thelid 14 closed onto the base 12 (as seen inFIGS. 2, 6 and 8 ). - As can be understood, the appropriate plastic of the desired mil thickness is provided, which is typically clear but may be translucent or otherwise. As well known in the thermoforming of clamshell containers, a sheet of plastic is placed into a tool, heated and trimmed to form a unitary body, as best seen in
FIG. 1 , with thelid 14 connected to thebase 12. A new andunique hinge member 16 is provided to connect thelid 14 to the base 12 to automatically provide the aforesaid alignment functionality during the lid closure process to ensure better and more reliable closure results. - Also, for example, the material used is preferably 0.025 inch Ga. Polyethylene terephthalate (“PETE”) plastic. The reinforcing
ribs 22 are optionally provided in different locations on thecontainer 10 to provide desired additional rigidity at those locations ofcontainer 10. Further, these reinforcingribs 22 may be provided of any desirable size and shape to make various portions of thecontainer 10 more rigid without increasing the thickness of the material used. - The
container 10 configuration is particularly well-suited for thermoformed containers that are made out of plastic, which may be transparent, translucent or opaque. The walls may be of, for example, 10 mil in thickness but may be of any desired thickness and flex. The profile of thehinge 16 may be modified so that it may spring in any desired direction to facilitate separation of thelid 14 from thebase 12. Thermoforming, using the appropriate tooling (not shown), is so well known in the art that it need not be discussed in detail herein. Suffice it to say that the tooling would be appropriately manufactured to provide the desiredbase 12,lid 14 and hinge 16 profiling.Containers 10 made out of other materials by other methods can also be achieved using the container with self-aligning lid described herein. - In view of the foregoing, a new and novel container with a self-aligning lid is provided. The unique self-aligning lid greatly assists in aligning the lid with the base before closing pressure is applied to the lid thus ensuring that the lid is optimally located when pressure is later applied to the lid for closure to the base thereby reducing risk of damage to the container or poor closure of the lid to the container. As a result, the container with self-aligning lid of the present invention is particularly well-suited for filling and closure by automatic machinery.
- It would be appreciated by those skilled in the art that various changes and modifications can be made to the illustrated embodiments without departing from the spirit of the present invention. All such modifications and changes are intended to be covered by the container with self-aligning lid and any appended claims.
