Food product containers with ids are described herein, and in particular, food product containers with lids that open and close.
Food products such as cookies, crackers and chips can be stored in a wide variety of plastic and paper-based containers. Such containers can include a separate lid that can be attached to a lip of a body of the container. Typically, such lids are manufactured separately from the container and increase the total cost of the container. In addition, separate plastic lids can confuse the consumer with complicated functionality or become misplaced.
Some containers are formed from one or more paperboard blanks that are divided by fold lines into a plurality of panels. Such containers can be cheaper to produce than containers with separate lids. Thee panels can provide an attractive id which can also protect the food product inside the container. Some examples of such containers are described in U.S. Pat. No. 4,850,528, U.S. Pat. No. 7,726,551, and U.S. Publication No. 2011/0095074. A disadvantage of such lids is that six or more such panels have to be simultaneously or sequentially manipulated when opening or closing such containers, which can make the opening and closing of the container a difficult and time consuming process.
A reclosable food container is provided. The container has a body for storing a food product. The body has a side wall extending between a closed bottom end and a top end including an access opening. The body has a lid, including a collar surrounding the body, the collar having a plurality of panels extending therefrom. The-collar is movable relative to the body in a direction between a first position wherein the panels overlie and restrict access to the opening and a second position. The second position is closer to the bottom end of the body than the first position. The panels permit access to the opening and are configured to shift in an outwardly direction during contact with the top end of the body during movement of the collar from the first position toward the second position. The lid assembly of the container provides a visually appealing and intuitive opening and closing experience.
The lid can include a hinged intersection between the panels and the collar. The intersection can be positioned above the top end of the body when the collar is in the first position. The hinged intersection can be positioned below the top end of the body when the collar is in the second position. The panels can shift in the outwardly direction about the hinged intersection during the movement of the collar from the first position toward the second position to permit access to the opening.
The panels can shift in an inwardly direction about the hinged intersection during the movement of the collar from the second position toward the first position to restrict, access to the opening. The panels can be biased toward an inwardly direction. Each of the panels can have two curved sides and a third side forming a linear hinged intersection with the collar. The collar and the panels can be separated by a fold line. At least two adjacent panels can be joined via at least one recessed panel and the recessed panel can be joined to the adjacent panels by at least one fold line.
The container can include a stop configured to restrict the collar from moving from the second position past the first position. The container can also include a stop configured to restrict, the collar from moving from the first position toward the bottom end past the second position.
The panels can be configured to form a dome when the collar is in the first position. The panels can be configured to form a concave surface when the collar is in the first position. The collar can be configured to rotate and twist at least a portion of the side wall to block access to the opening.
In one approach, the side wall can include a first threaded portion and the lid assembly includes a complementary second threaded portion that permits the lid assembly to be attached to the body of the container by rotation. The lid assembly is configured to move from the first position toward the second position by rotational movement alone the first threaded portion.
A method of using the container is also provided. The method includes moving the collar in a direction from the first position toward the second position; bringing the panels into contact with the top end of the body to shift the panels outwardly and permit access to the opening; and removing the food product from the container. The method can further include moving the collar from the second position toward the first position to allow the panels to shift inwardly, optionally at least partially under self-bias, to restrict access to the opening.
A food storage container includes a body and a lid assembly movable with respect to the body. The lid assembly includes a collar surrounding the body and a plurality of panels extending therefrom. With the collar being in a first position, the panels cover an access opening of the container and restrict access to a food product stored in the container. When the collar is moved toward a second position, the panels pivot away from the access opening to provide access to the food product in the container. A comparatively simple downward movement can result in a more complex outward movement of the panels. The panels can have decorative shapes resembling, for example, flower petals.
When being opened by a user, the panels of the lid assembly can imitate a blooming flower to provide a user with a visually pleasing experience. The container can be reclosed by moving the collar back to the first position such that the panels return to their closed orientation, such as due to a self-bias from the shape and orientation of the panels. Again, simple movement of the collar results in a more complex inward movement of the panels. Thus, the container advantageously has a lid that can be both decorative and provide a way to open and reclose the container using simple movements of the collar which translate into complex movements of the panels.
With reference to
The body 11 of the container 10 can be in the form of a cup, a bag, or the like. The body 11 of the container 10 can be rigid and made from a paper, cardboard, plastic or the like. Alternatively, the body 11 of the container 10 can be made of a flexible material such as film, polyethelyne, polypropylene, polyvinyl chloride, polystyrene, polytetrafluoroethylene, or the like, so that the shape of the food product in the container 10 would impart a shape to the body 11. It is to be appreciated that the body 11 can be entirely rigid, entirely flexible, or rigid in part and flexible in part. The body 11 can be formed by injection molding, blow molding, or the like.
With reference to
The collar 22 can be hexagonal as shown in
With reference to
As such, the film 29 can act as a stop for the collar 22 to restrict motion of the collar 22 both in the upward and downward directions. The upward stop can be useful, for example, because the upward stop can restrict the user from inadvertently taking the lid assembly 12 off the body 11 of the container 10 when moving the lid assembly 12 upward with the intention of reclosing the container 10. The film 29 can be made from a material that is flexible but sufficiently strong to prevent ripping of the film 29 when it is being stretched out. For example, the film 29 can be made of metalized or non-metalized polyethylene or polypropylene. It is to be appreciated that as an alternative to the film 29, the lid assembly 12 may be in a friction fit with the side wall 13 of the body 11. In another approach, the lid assembly 12 may be attached to the side wall 13 of the body 11 of the container 10 by an adhesive or other suitable means.
The panels 24a-f of the lid assembly 12 have two positions of stability—the closed position shown in
The panels 24a-f and intermediate sections 25a-f of the lid assembly 12 can be shaped and arranged in a variety of predetermined decorative patterns. For example, a flower shape as shown in
The body 11 may optionally he provided with an initial hermetic seal to protect the food product stored in the container 10. For example, a peelable film can be sealed to the top end 16 of the body 11 of the container 10. In this approach, after the collar 22 of the lid assembly 12 is moved toward the second (open) position and the panels 24a-f shift to the open orientation, a user could remove the peelable film to reveal the access opening 20 and gain access to the food products in the container 10. Thus, the peelable film can provide a tamper-evident feature such that the absence of the peelable film could indicate to the consumer that the container 10 has been previously opened.
In another approach, the peelable film could be sealed to the exterior surface of the panels 24a-f such that the user could peel off the film before moving the collar 22 to the open position. Alternatively, the film can be peeled off during movement of the collar 22 from the closed position (
In yet another approach, the panels 24a-f and the intermediate sections 25a-f of the lid assembly 12 can form an initial hermetic seal over the access opening 20 of the body 11. In this approach the lid assembly 12 can be utilized to open the seal utilizing one or more lines of weakness formed between one or more of the panels 24a-f and the intermediate sections 25a-f to tear the seal and open the lid assembly 12 upon the downward sliding of the collar 22 from the closed position to the open position. The line of weakness may be a score line or a perforation line formed in the seal between the panels 24a-f. The line of weakness can be formed by laser ablation, die-cutting, micro-abrasion, or the like.
Optionally, the container 10 may be provided with the panels 24a-f being at least in part concave such that when the container 10 is opened by a user and reclosed, the concave portions of the panels 24a-f pop up back to the dome-shaped or convex orientation shown in
With reference to
In order to open the container 10, a user can grasp the collar 22 of the lid assembly 12 and move the collar 22 in a direction toward the bottom end 14 of the container 10. As the collar 2 moves in a downward direction, the interior surfaces of the panels 24a-f come into contact with the top end 16 of the container 10. The panels 24a-f are then urged by the top end 16 of the container 10 to shift away from the central axis of the body 11 to an open orientation that provides the user access to the opening 20 as shown in
When the collar 22 is in the open position shown in
In reference to
Optionally, the container 10 can have a flexible side wall 13 and may be reclosed by rotating the collar 22 in a clockwise or counterclockwise direction about the central axis of the body 11. Since the collar 22 is connected to the flexible side wall 13 of the body 11 by the flexible film 29, a portion of the flexible side wall 13 would turn during the rotation of the collar 22 to form a twisted configuration that would reclose the container 10 by substantially blocking the access opening 20. In order to reopen a container 10 that has been reclosed, the collar 22 can he counter-rotated to untwist the twisted configuration such that the access opening 20 again becomes accessible such that the food product can be removed from the container 10. After the user removes the desired portion of the food product from the container 10, the food product remaining in the container 10 can be again reclosed as discussed above.
The container 10 can have a length as measured from the top end 16 to the bottom end 14 of about 2 inches (50 millimeters) to about 14 inches (350 millimeters), and a width of about 1 inch (25 millimeters) to about 6 inches (150 millimeters). The side wall 13 of the container 10 may have one or more layers and may have a thickness of about 0.005 inches (0.1 millimeters) to about 0.05 inches (1 millimeter). It is to be appreciated that the dimensions of the container 10 have been provided for illustration purposes only, and that the principles of this disclosure can be utilized in connection with flexible film packages of any size.

The blank material 30 is provided with a plurality of vertical fold lines 32a-e. The fold lines 32a-e can extend from the bottom end 42 of the blank material 30 and can be parallel, converging, or diverging relative to one another. Fold lines 32a-e divide the blank material 30 into six sections 38a-38f, which will form the sides of the hexagonal collar 22 when the blank material 30 is folded to form the lid assembly 12. The fold lines 32a-e can be formed by a laser or other suitable means and provide crisp or otherwise defined edges to the collar 22 as shown in
With continuing reference to
The blank material 30 is further provided with a plurality of fold lines 44a-f that can extend from the sealing area 34 to the second side 36 of the blank material 30. The fold lines 44a-f are curved and can be in an undulating, sinusoidal or any other suitable pattern. The portions of the blank material 30 formed between the intersection line 26 and the fold lines 44a-f define the panels 24a-24f of the lid assembly 12. The portions of the blank material 30 formed between the top end 40 and the fold lines 44a-f define the intermediate sections 25a-25f of the lid assembly. Similar to the fold lines 32a-e, the intersection line 26 and the fold lines 44a-f can be formed in the blank material 30 by a laser or by other suitable means. It is to be appreciated that any one of the fold lines may be formed by a partial removal of the material across the thickness of the blank material 30. Alternatively, any of the fold lines 32a-f, 26, and 44a-f can be formed by a complete removal of the material across the thickness of the blank material 30 so as to create a perforation line.
To construct the lid assembly 12, the blank material 30 shown in
With reference to
The lid assembly 112 has a collar 122 which extends around the side wall 113 of the body 111 and a plurality of panels 124a-d extending from the collar 122. The collar 122 is shaped and sized to match the outer perimeter of the body 111 of the container 100. The body 111 of the container 100 and the lid assembly 112 can be attached to one another by a flexible film similar to the film 29 shown in
The lid assembly 112 includes two generally rectangular panels 124a and 124c and two triangular panels 124b and 124d as shown in
The body 111 of the container 100 and the lid assembly 11.2 can be made from the same materials as the body 11 and the lid assembly 12 of the container 10, respectively. Similarly to the collar 22 and the panels 24a-f, the collar 122, the panels 124a-d, and the intermediate sections 125a-d can incorporate a memory-shape material so that the panels 124a-d can open from a closed position and subsequently return back to the closed position.
The panels 124a-d of the lid. assembly 112 have two positions of stability—the closed position shown. in
It is to be appreciated that while the panels 124a-d have been shown in
The container 100 can be opened by the user substantially the same way as the container 10. More specifically, when the container 100 is in the closed position as shown in
The panels 124a-d move from the closed orientation of
After the use has removed some but not all of the food product from the container 100, the user may move the collar 122 in an upward direction away from the bottom end 114 toward the closed position. As the collar 122 is being moved up by the user, the intersection 126 between the panels 124a-d and the collar 122 coincides with or crosses the top end of the body 111. The since the panels 124a-d are biased toward the closed orientation, the panels 124a-d pivot from the open orientation shown in
The blank material 130 is provided with a plurality of vertical fold lines 132a-c. The fold lines 132a-c can extend from the bottom end 142 of the blank material 130 and can be parallel, converging, or diverging relative to one another. The first side 133 of the blank material 130 can include a sealing area 134 which can be attached to the second side 136 of the blank material 130 by an adhesive or other suitable attachment means.
The fold lines 132a-c divide the blank material 130 into four sections 138a-138d, which will form the four sides of the collar 122 when the blank material 130 is folded to form the lid assembly 112. The fold lines 132a-c can be formed in the blank material 130 the same way as fold lines 32 can be formed in the blank material 30 discussed above.
The blank material 130 is provided with a fold line which forms the intersection 126 between the panels 124a-d and the sides 138a-138d of the collar 122. The fold line 126 can extend between the sealing area 134 and the second end 136 of the blank material 130 and is perpendicular to the fold lines 132a-c. It is to be appreciated that the fold line 125 can be at any other angle to the fold lines 132a-c and may be at least in part curved instead of being straight.
The blank material 130 is further provided with a plurality of fold lines 144a-d. The fold line 144a extends from the intersection of the fold line 132a and the fold line 126 to the top end 140 of the blank material 130. The fold line 144b extends from the intersection of the fold line 132b and the fold line 126 to the top end 140 of the blank material 130. The area between the fold lines 144a, 144b, and 126 forms the panel 124b, which can be in the form of an isosceles triangle as shown in
The fold line 144c extends from an intersection of the fold line 132c and the fold line 126 to the top end 140 of the blank material 130. The fold line 144d extends from an intersection of the second end 136 and the fold line 126 to the top end 140 of the blank material 130. The area between the fold lines 144c, 144d, and 126 forms the panel 124d, which can be in the form of an isosceles triangle as shown in
With continuing reference to
The area between the fold line 146a, the top end 140 and the fold line 144a forms the intermediate section 125a. The area between the fold line 144b, the top end 140, and the fold line 146b forms the intermediate section 125b. The area between the fold line 146c, the top end 140, and the fold line 144c forms the intermediate section 125c. The area between the fold line 146d, the to end 140, and the second side 136 of the blank material 130 forms the intermediate section 125d. Similar to the fold lines discussed in reference to
