This invention relates to packaging and more particularly relates to containers for storing and dispensing products such as comestibles.
Consumers desire product packages or containers from which product pieces are easily dispensed. Especially, consumers desire dispensable product containers which may be manipulated with one hand to open the container for product removal. Further, a desirable container does not open accidently to spill product contents.
An additional desirous feature of a consumer package is an ability to fill the package or container easily with commercial manufacturing equipment and processes.
A container suitable for dispensing comestible products has a body with a top face segment having an opening and a concave top face segment and a separate continuous member connected to a side face, the member having an openable lid portion which covers the opening and a flexible press portion extending from the lid portion to the side face over the concave top segment face, which is normally convex to the concave top face segment, wherein application of a downward force to the convex flexible press portion transforms the convex portion to a concave portion and rotates the lid portion to uncover the opening.
This invention is directed to a container from which separate product pieces such as comestible products may be dispensed. Such container has a body portion typically constructed of a material such as a plastic, which has sufficient stiffness to retain a shape upon application of typical hand force at room temperature. A body portion has a top, a bottom face, a front face, a back face and at least one side face. The top has at least two face segments in which one such face segment has an opening to the interior of the container and a second top face segment which is attached to the first top face segment and is sloped toward, and is concave to, the bottom face. The first top face segment, which contains the opening, may be angled with respect to the bottom face such as up to 5, up to 10, up to 20 or more degrees for ease of dispensing product or may be parallel to the bottom face. “Parallel” means that plane of the first top face segment and the plane of the bottom face are parallel to an ordinary observer, such as may be constructed using typical manufacturing techniques. Plastic material suitable for a body includes polyethylene, polypropylene, polyolefin copolymers, polystyrene, polyester, polycarbonate, and the like.
In an aspect of the invention, a separate continuous flexible member is connected to a side face such that a portion of such flexible member wraps over the top face and has a lid portion which covers the container opening and a flexible press portion which extends from the lid portion to the side face and normally forms a convex portion over the concave top face segment. Typically, the flexible member is connected to top face at the junction of the first top face segment (containing the opening) and the second concave top face segment. Such connection typically provides an axis of rotation around which the lid portion may rotate from a closed position to an open position.
A suitable flexible member useful in this invention is constructed from a flexible material such as a flexible plastic. Although flexible, a suitable material typically has sufficient stiffness such that the flexible press portion retains shape and when the press portion is pressed, sufficient force is applied to rotate the lid portion. An example of such a material is a polyolefin thermoplastic elastomer. Alternatively, suitably flexible grades of other polymers such as polypropylene, high density polyethylene, low density polyethylene, and olefin copolymers such as ethylene-propylene copolymers may be used. Typically, a suitable material provides enough opening force to overcome the snap fit of the lid and is sufficiently flexible to deform upon application of hand force. Preferably, the flexible member is molded as a single continuous piece and incorporates a side portion, a press portion, a lid portion, and optionally an opening insert portion and a bottom portion. The flexible member is separate in a sense that the member is constructed from a different material or different grade of a material than the body and is connected to the body. The container body and flexible member may be the same or different color. The flexible member may provide a grip area on the top or bottom to facilitate handling of the container as well as stacking upon a display.
The flexible member includes a lid designed to cover the top opening of the top face segment in the body. The lid may fit into the opening with an insert, which typically extends downward from the lid into the opening and may only include one or more sides to engage the opening. The lid also may have a catch which engages an indent portion of the insert. The catch functions such that when the lid is pressed into the opening, the catch bends slightly inward and then falls into stationery engagement with the indent portion. Typically, the lid is resistant to accidental opening.
The press portion also may include a reinforced band or ribs to provide the press portion with additional rigidity and provide for additional material flow during forming of the flexible member. The press portion may include ridges or text such as “press here” to indicate to the user where to engage the press portion. In operation the press portion normally moves from a convex position to a concave position.
In a further aspect of this invention, the flexible member may be connected by suitable means such as mechanically or adhesively to a side face. Alternatively, the flexible member attached to the body may be produced by overmolding a flexible polymer onto the body. In another aspect the flexible member may incorporate an insert portion hinged to the flexible member and adapted to fit within the top face body opening. In such aspect, the lid portion is adapted to engage the insert and to close and open within the insert portion.
The side face to which the flexible member is attached typically is flat to promote a firm adhesive or mechanical connection. The opposing side of the container body may be curved, which forms a curved spout structure at the container opening. In another aspect, the opposing face is flat. The container body may include variations wherein the spout structure is independent of, and detachable from, the body.
In operation, a consumer applies a downward force to the convex flexible press portion to conform the flexible press portion to the concave top face segment, which thereby acts to rotate the lid portion such that the opening is uncovered. After such action, product pieces in the container may be removed by the consumer. The lid portion may be closed manually by the consumer by pressing the lid back into the opening. Typically, a consumer is able to open the container lid in a one-handed operation in which a consumer's thumb applies force to the press portion.
In another aspect of this invention, the bottom face may contain an opening which may be covered by an extension of the flexible member portion or may be covered by a separate removable cover. The purpose of this bottom opening is to provide access to the container for filling product pieces. In this aspect, the bottom opening cover, whether a separate portion or an extension of the flexible member may be mechanically or adhesively sealed after filling. A preferred aspect includes a bottom portion which is part of the continuous flexible member connected to the side face. A larger open bottom facilitates container filling in contrast to filling through a relatively small top opening. Additionally, an open bottom may permit a secondary means of dispensing product if a user desires to remove multiple pieces of product. Alternatively, after an open bottom may be used to fill container, a bottom cover is fused shut and not openable by a user. An overwrap such as shrink wrap may enclose the container and provide tamper evidence.
In an alternate embodiment, an opening larger than the top opening may be provided in the side face of the body. In such an embodiment, the opening then could be covered the flexible member. Still alternatively, an opening larger than the top opening may be provided in front and back faces and may be covered by a label.
A suitable flexible member also may have a hinged bottom portion as part of the flexible member. The bottom portion may have an insert outer edge which conforms to the bottom of the body and a gasket insert which conforms to a lower channel of the container. The bottom portion may be designed to cover an open bottom of the body or it may be added as a decorative or functional portion to a closed bottom. The bottom portion also may be fastened with a means to remove the bottom piece from the bottom body. Alternatively, the bottom portion may be a separate fused piece or be a preformed part of the body.
The container body may be molded in two steps and then have the flexible member joined to the body. Typically, the flexible member is connected firmly to the side face of the body, especially at the top edge of the side face from which the press portion extends. Also, the press portion of the flexible member is attached firmly at the edge of the top face segment. These firm connections permit the press portion to direct force from deformation of the press portion to open the lid. If the flexible member is not connected securely to the body at the points which form the press portion, the ability to open the lid is compromised.
The connection between the press portion and the top face segment which incorporates the opening is adapted to form an axis of rotation around which the flexible member containing the lid may rotate upon application of force to the press portion. Such an axis may be along the edge line of the top face portion. In another embodiment, the connection between the press portion and the body at the top face may be a protrusion connected to or a part of the flexible member which mechanically fits or snaps into a suitably sized receptacle formed within the body at the top face. This connection provides a rotation axis around which the lid portion may open upon applying force to the press portion.
The dispensable product container may be hooked through the press portion with clips, hooks, carabineers and the like. Also the flexible portion may be fully pulled away from the top opening to permit the press portion to be positioned around a ring, belt loop and the like. Other embodiments of the dispensable product container may use a rigid press portion as a loop and instead open through a rigid-snap lid. These are but a few of the variations within the scope of this invention.
In a typical container of this invention a side face of the body may be curved. A spout and the top opening may follow or incorporate this curve. Additionally, the bottom face of the body also may follow or incorporate the shape of a curved side face and the generally rectangular front and back faces. The front and back faces of the container body may be flat and accommodate graphics describing the contents of the container. However, the shape of the container body may vary and include flat, curved, or polygonal faces.
In an aspect of this invention, the container is sized and shaped to be conveniently fit into a user's hand or pocket. The container is scalable to a variety of sizes, which may include up to fifteen, twenty-five, forty, sixty, or greater number of product pieces.
This invention provides a container suitable contain and dispense individual product pieces such as comestible products such as a chewing gum. Such product pieces may be of any shape or size compatible to the container. Examples of suitable shapes include tablet, pill, chunk, flat stick, pillow, round, rectangular, triangular, and combination thereof. A typical example of suitable comestible product pieces includes chewing gum pellets and other confectionary or food products. Additional dispensable product pieces include pharmaceutical products.
