Abstract

A package for use in holding, dispensing, and spreading a viscous substance, such as a condiment. The package may include a thin-walled rigid planar member with at least one centrally-located opening, a flexible membrane forming a sealed reservoir on one surface and a flexible membrane forming a removable cover over the opening on the opposing surface. The reservoir membrane may be permanently sealed to the rigid planar member about a perimeter that surrounds the perforation. The cover, reservoir membrane and the rigid planar member form a sealed cavity with which to safely store and transport the contents, with the cover being removed for dispensing and spreading purposes.

Description

FIELD OF THE INVENTION

The present application is generally related to the single-use/disposable packaging industry. More specifically, the application is directed to a single-use sealed condiment package that provides dispensing, spreading, and cutting functionality.

BACKGROUND

With busier schedules and less time spent at home, more food is consumed on-the-go. This shift in the way we eat has increased the popularity of fast food, take-out, delivery, and street-fare options, all of which must provide not only the food, but also the packaging, cutlery, and other items needed to make eating fast and convenient. Even traditional store-bought foods, such as fruits and vegetables, are being packaged and marketed as single-serving, on-the-go items for children and working professionals. As such, the disposable packaging industry has experienced substantial growth over the years, with multiple new packaging designs and combination products—such as those presented in the prior art—being developed to help facilitate this lifestyle-shift.
Single-use packaging for condiments and other convenience items, commonly referred to as sachets or packets, are flexible pouches that are filled with small amounts of condiment and then hermetically or heat-sealed on both ends. Typically, the ends are serrated to provide a means to grip and tear or open the package, at which point the user then squeezes the pouch to expel the contents onto the food. This form of packaging provides a low-cost and relatively low-contamination method of distributing condiments and other items necessary for on-the-go meals.
Unfortunately, the current package design is focused on holding the contents but does not account for ultimate intent or usability. Most sachets are made from thin plastic, tin foil or mylar—flexible materials that enable portability and keep cost low but are poorly suited for the actual dispensing and spreading functions. Dispensing the contents is often awkward, requiring both hands to force the contents out of the pouch and onto the food. Often the contents are spread unevenly, requiring the use of a separate knife or, as is often used, the unsanitary side of the sachet itself to facilitate spreading. This is especially true with viscous substances such as mayonnaise, which tend to adhere to the package rather than flow evenly onto the food. This process often leads to unnecessary mess and a great deal of waste—unused condiment left in the package, extra napkins, and the extra utensils required for spreading.
Therefore, a need exists for an improved sealed condiment package. Ideally, the improved package would hold a single-serving amount of condiment or other substance, would provide a simple, efficient method of transferring condiment to the food, and would feature integrated spreading and cutting functionality in a single, low-cost design. At least some of these objectives will be met by various embodiments described below.

BRIEF SUMMARY

The present application describes a condiment package with integrated spreading and cutting functionality. In one aspect of the present invention, a condiment package may include a thin, rigid planar member, which may in one embodiment be triangular- or fan-shaped. This thin, blade-like structure may include at least one hole or perforation placed centrally toward the larger, flared distal region of the shape. In some embodiments, a flexible membrane made from plastic or similar material may be permanently sealed to one side of the planar member, with the seal region forming a perimeter around the centrally-located hole. The cavity formed from this membrane and one side of the planar member serves as a reservoir for condiments or other materials. Another flexible membrane may be sealed over the hole on the opposing side of the planar member, providing a lid or cover which can be removed to dispense and spread the contents. In one embodiment, this seal may extend futher onto the leading or distal surface of the planar member. Once removed, the surface below the seal may provide a non-contaminated region with which to spread or distribute the contents onto food.
In another embodiment, the distal edge of the large or flared shape may be serrated or beveled to provide a rigid cutting feature with which to cut or manipulate food. In another embodiment, the side of the planar member opposite the flexible reservoir may feature a contoured surface to enhance grip and control for single-handed operation for the user while dispensing the contents of the package.
These and other aspects and embodiments are described in greater detail below, in conjunction with the accompanying figures. It should be noted, however, that the figures are for illustrative purposes only and are not intended to exclusively define or limit the scope of the present invention as set forth in the claims of this application.

DETAILED DESCRIPTION

Referring to FIGS. 1A-1C, a condiment package 110 is shown in its sealed configuration, according to one embodiment. In FIG. 1A, the frontal perspective view illustrates two visible components of package 110 comprising planar member 112 and flexible membrane cover 114. The planar member 112 is shown in a roughly egg- or fan-shaped profile, according to one embodiment. In other embodiments, this profile might be circular, rectangular, or a shape optimized for gripping, dispensing, and spreading the contents. Additionally, in order to perform these functions the planar member 112 should provide a rigid or semi-rigid backbone for the package 110. As such it should be of appropriate thickness and made from a durable, lightweight material such as plastic. Elevated features to assist in single-hand operation, such as grip 130, may in one embodiment be incorporated into the planar member 112. The flexible cover 114 is shown sealed to region 120 of the visible planar surface 112. Note that only a portion of the cover 114 is sealed to the planar member 112, leaving a portion free to grip and remove to open the reservoir and dispense the package contents. The region 120 might, in one embodiment, be elevated above the planar member 112 to provide a definitive sealing surface and help the user to grip the un-sealed portion of the flexible cover 114. The planar member 112 also comprises a distal edge 118 and distal surface 126, both of which provide a spreading and manipulating feature for the contents of the package.
FIG. 1B shows the condiment package 10 from the opposing rear perspective view. Again, the package 110 is shown in the as-sealed configuration, with flexible membrane reservoir 116 forming a dome or pouch which will hold the contents of the package between its inner surface and the planar member 112. The flexible reservoir membrane 116 is shown with a perimeter that is roughly circular in one embodiment. In other embodiments, the perimeter may be oval, elliptical, rectangular or another shape suitable for forming a reservoir to hold material. This perimeter is sealed to the surface of the planar member 112 in a permanent fashion. The reservoir membrane 116 must be flexible enough to be deformed for the purpose of expelling the contents while at the same time be rigidly fixed to planar member 112 such that it cannot be removed after manufacture. Accordingly, this membrane can be made of flexible plastic, foil, mylar or a similar material. In the figure, the distal edge 118 of the planar member 112 is shown with a row of serrations 128. These serrations are shown on one side only, but in other embodiments could be present on both sides of planar member 112. The serrations 128 allow package 110 to be utilized as a cutting tool as well as a dispensing and spreading tool.
FIG. 1C shows a side profile view of the package 110, illustrating the linear and thin aspects of the planar member 112. The flexible membrane 116 is shown sealed to one side of the planar member 112, forming a protruding reservoir of ample volume to hold the contents. Flexible cover 114 is shown partially sealed to the opposing side of planar member 112, with a small portion unsealed to provide easier removal during use. Distal edge 118 is shown to terminate in a sharp edge in one embodiment, which may help facilitate the spreading and cutting functionality of the package 110. In FIG. 1D, the package 110 is shown in the exploded pre-sealed state from the rear perspective view. Here all three components can be clearly distinguished--the rigid planar member 112, the flexible cover 114 used to form the removable seal, and the flexible membrane 116 used to form the sealed condiment reservoir. A hole 124 extends through the planar member 112. The circular perimeter of the dome-shaped reservoir membrane 116 will seal approximately as shown along the dashed lines of region 122. The shape of this region will depend on the specific shape of the perimeter of reservoir membrane 116, but generally this perimeter and seal region 122 will fully surround opening 124. When assembled, reservoir membrane 116 will thus form a reservoir that can be filled with condiment through opening 124, be fully sealed with flexible cover 114 for storage and transport, and be used to dispense condiment through opening 124 when flexible cover 114 is removed during use.
Referring now to FIG. 1E, the package 110 is shown in the exploded pre-sealed state from the frontal perspective view. In this view, the internal concave surface of reservoir membrane 116 is clearly seen. Once sealed to planar member 112, this surface will form the reservoir to hold the contents of the package. Additionally, the perimeter region 132 of membrane 116 is shown. This region, which can vary in shape and cross-sectional thickness, will form one part of the permanent seal. The position of the opening 124 is shown with respect to the seal region 120 of the flexible cover 114. When sealed, this membrane will cover opening 124 and provide an aseptic barrier for the contents of the package.
A detailed view of the distal section of planar member 12 is shown in FIG. 1F. This view provides a closer look of the serrations 128 along distal edge 118. As mentioned previously, these serrations allow the package 110 to perform the additional functions of a cutting and spreading utensil.
FIG. 2 shows a package 210, according to an alternative embodiment. In the embodiment illustrated, the single opening 124 of the previously described embodiment is replaced with an array of holes 224. These holes can be of varying size or shape and can arranged in varying patterns, as long as each feature extends all the way through the rigid planar member 212 and is fully surrounded by the perimeter seal of the flexible membrane reservoir 216. Additionally, the flexible cover 214 is shown modified to fully cover the array of holes 224. Ideally, the pattern would serve to optimally dispense and spread the contents using the distal portion 226 of the planar member 212.
In FIG. 3, a frontal view of a package 310 is shown, according to another alternative embodiment. In this embodiment, the flexible cover 314 is shaped so as to extend the sealed region down to the distal edge 318 of the rigid planar member 312. The flexible cover 314 would be sealed distally, with an unsealed region above region 320 that provides a pull-tab for removal. This extended flexible cover 314, when removed, leaves a larger uncontaminated region for dispensing and spreading the contents of the package. This is especially advantageous for a single-use sealed condiment package application, since transport and storage are often performed in uncontrolled, potentially contaminated conditions.
Referring to now to FIGS. 4A-4D, which illustrate the package 410 in multiple stages of use. FIG. 4A depicts the first stage of use, wherein the user's hand H is shown removing the flexible cover 414 from the sealed region 420 of planar member 412. The unsealed portion of flexible cover 414 is presented as a means to grip between the thumb and index finger. When pulled in the direction of the arrow, removal of flexible cover 414 provides access to opening 424 and the condiment reservoir. In FIG. 4B, the package 410 is shown in use, with its contents being dispensed. In this figure, the flexible cover 414 has been removed, leaving the opening 424 unsealed. With single handed operation from user H, a pressure—indicated by arrows—is applied to the flexible membrane 416 with the index, middle, or any combination of fingers while the package 410 is gripped with the thumb in contoured region 430. Pressing downward and toward the distal end 418, the entire contents 438 of the package can be expelled from the flexible membrane reservoir 416 through opening 424. Referring now to FIG. 4C, the condiment package 410 is shown being utilized in a spreading capacity. Here the user H grips the package 410 and dispenses contents 438 distally as illustrated in FIG. 4B while moving the package in the transverse along the spreading substrate—in this case bread B. The distal spreading surface 426 and distal edge 418 provide a means to evenly spread the contents 438 onto the substrate. Finally, in FIG. 4D, the package 410 is shown in use as a cutting device. With the grip demonstrated in FIGS. 4B-4C, the user H can use the distal edge 418 to cut or manipulate food item B. The addition of serrations 128 as in FIG. 1F can assist in this cutting functionality.
