The present invention relates to spreading devices and in particular relates to spreading devices for applying spreadable substances to surfaces.
Effective application of spreadable substances, such as applying butter to hot corn, has been a problem for decades. The problem that exists with butter knives and hot corn was acknowledged as early as 1946 in U.S. Pat. No. 2,478,122 to Max N. Mossel: “the wasteful messiness of using a knife to apply the butter” (Col. 1, lines 13-14). Similarly, in U.S. Pat. No. 2,750,767 to Emil W. Von Knauf (“Von Knauf”): “the butter commences to melt and slide down the corn out of control of the butter knife” (Col. 1, lines 18-20).
This spreading problem is not limited to applying butter to hot corn. Difficulty in applying spreads to other surfaces—such as applying cream cheese to bagels or jam to bread—can occur when knives are used. For example, the use of a knife in these situations may result in clumpy or uneven distribution of a spreadable substance. In addition, the use of, for example, a pointed applicator for dispensing edible (e.g., honey) or non-edible (e.g., glue) spreadable substances may similarly result in uneven distribution, particularly where the applicator itself is impractical to use for spreading or the use of a knife would be impractical in the circumstances.
While various solutions for applying spreadable substances have been described in the prior art, such solutions are deficient in various ways.
Von Knauf discloses a spreading device for applying butter to hot corn. The Von Knauf device attempts to confine the butter as it is being applied and allows the user to manually press the butter towards the corn to facilitate spreading.
The device handle (3, 25) and the butter press (18, 30) are two separate features. Operation of the device is described as follows: “The operator, holding the spreader at the flange 3, can then press his finger at the center of the butter holder, thus pressing the flour flaps 18 downwardly and pressing the cardboard bottom 19 downwardly to force the butter into contact with the ear of corn” (Col. 2, lines 60-64). Such operation is disadvantageous in that a user would use one hand to perform multiple functions (i.e., fingers to hold the device and a finger to press at the butter holder), thus requiring a certain degree of coordination. In other words, a level of coordination is required to operate the device because the holding and pressing actions are controlled independently.
In addition, in order to confine the butter in the spreading device, Von Knauf employs tabs (12). The butter, or other spread, must be forced past the tabs and into the compartment (6) of the spreading device. However, given the tabs are moveable to allow movement of the butter (see Col. 2, lines 55-58), spreads such as butter may unintentionally leave the compartment during use. This may occur as a result of a user pressing on the butter holder to a sufficient degree so as to allow the butter to escape, either because the tabs moving outwardly and allow the butter to escape, or because the force applied to the butter holder is sufficient enough that the tabs 11 are insufficient to contain the butter, particularly since the tabs 12 only cover a limited surface area of the compartment. Alternatively, this may occur as a result of a spread being pressed towards a hot surface, the spread then melting, and tabs 12 no longer confining the spread within the compartment of the spreading device, even in cases where reduced or no force is applied to the butter holder, again recognizing that this problem is aggravated by the fact that the tabs 12 only cover a limited surface area of the compartment.
A “Butter Storing and Spreading Device” was disclosed in 1970 by Asad F. Isaf in U.S. Pat. No. 3,545,873 (“Isaf”). The main object of Isaf is to effectively store a spreadable patty in a sanitary manner. This object is accomplished by placing a cover 24 over the spread. Before applying the spread, the cover is removed. With the cover removed and the spread ready for spreading, there is no feature to allow a user to press a finger or other structure against the butter, as there is a base (14) of heavy paper or cardboard between the butter and the device handles (22). This may result in less flexibility with respect to the manner in which the butter is spread. In addition, with the cover removed, there is no feature that confines the spread within the spreading device. Accordingly, the spread may not remain in place once the spreading device is inverted, or the spread may be more susceptible to separation from the spreading device.
A similar device to Isaf was disclosed by Ronald F. Reda in United States Patent Publication No. 2009/0148571 titled “Disposable Spreading Device for Edible Spreadable Compounds” (“Reda”). One difference between Isaf and Reda is that Reda discloses that the spread is fixed to the spreading device, such that the spread remains in place when the device is inverted.
However, Reda, like Isaf, does not include a feature to allow a user to press a finger or other structure against the butter, as there is a body (120/320) comprising a handle (110/310) such that a user would hold the handle with their fingers and slide the device along, for example, a cob of corn. This may result in less flexibility with respect to the manner in which the butter is spread.
In addition, Reda fails to disclose a container to enclose the spread when the device is in the storage configuration. Rather, Reda uses a protective paper (160/360) that does not cover the edges of the spread, which may result in contamination issues during distribution and storage. While Reda does disclose a method of packaging multiple spreading devices together, a method of packaging or storing a single spreading device in a sanitary fashion (e.g., in a completely enclosed fashion) is not disclosed.
An additional, alternative and/or improved spreading device is desirable.

Features, aspects and advantages of the present disclosure will become understood from the following detailed description, taken in combination with the appended drawings, in which:
Generally, the spreading device may comprise a container and at least one gripping or handling surface. With reference to the embodiment depicted in
In the further alternative, the spreadable substance 6 may comprise a granular substance, such as salt or pepper, whereby the spreading device 1 may be used as, for example, a shaker. When the device 1 is in use as a shaker, the gripping or handling surfaces 3a, 3b are held by the user and the spreading device 1 may be held over the spreading surface and shaken to dispense the granular spreadable substance 6 through the filter 4 and onto the spreading surface. The skilled person will understand that, where the spreadable substance 6 is a granular substance, a removable layer 5 may be required in order to prevent premature dispensing of the granular spreadable substance 6.
The spreading device is depicted as having a top (as shown in
In the storage position, the container 2 may be visible and exposed at the top of the spreading device, as is shown in
Still in the storage position, the at least one gripping or handling surface may cover at least a portion the bottom of the spreading device. At the bottom of the spreading device is a dispensing end or outlet of the container. Preferably, as shown in
The storage position as described may allow for compact packaging, distribution, storage, shelving and/or efficient use of space with respect to the spreading device. In addition, the storage position may allow for sanitary distribution and storage of the spreading device because the spreadable substance 6 located in container 2 is not exposed to the surrounding environment. Rather, the spreadable substance 6 within the container 2 may be covered or protected at least in part by the filter 4 and the gripping or handling surfaces 3a and 3b, and substantially sealed inside the container 2 by the removable layer 5 and the material of container 2 itself. The spreading device as described may therefore reduce the chances of contamination of the spreadable substance when the spreading device is not in use, such as when it is in the storage position.
When it is desired to apply the spreadable substance to a surface, the spreading device may be moved from the storage position to the spreading position. The spreading position is achieved by moving the at least one gripping or handling surface from the storage position to a position such that at least a portion of the at least one gripping or handling surface may cover at least a portion of the top of the spreading device.
Preferably, at least a portion of the at least one gripping or handling surface may cover or contact at least a portion the top of the container 2. With particular reference to
Preferably, the at least one gripping or handling surface extending from the container has a minimum length such that when it is bent, flexed, pivoted or folded in the direction of the exterior surface of the container at least a portion of the at least one gripping or handling surface is able to come in contact with at least a portion of the exterior surface of the container.
In order to facilitate the bending, flexing, pivoting or folding of the at least one gripping or handling surface, bendable/flexible points, folding/pivoting edges or hinges may be provided. The bendable/flexible points, folding/pivoting edges or hinges may be provided in order to facilitate movement of the at least one gripping or handling surface from the storage position to the spreading position, and vice versa. Preferably, the bendable/flexible points, folding/pivoting edges or hinges comprise integrated flexible plastic pivot edges 7. In the alternative to bendable/flexible points, folding/pivoting edges or hinges, the at least one gripping or handling surface may be made from a material that is generally flexible or bendable.
As shown in
In another embodiment as depicted in
As noted above, the spreading device may include a removable layer or sticker 5. If the spreading device 1 includes a removable layer 5, then prior to use of the device (i.e., prior to applying the spreadable substance 6 to a surface) a user should remove the removable layer 5. The removable layer 5 acts as a contamination barrier. That is, it is a sanitary layer that may be included for protection of the spreadable substance 6 during the period in which the device is not in use, such as when it is in the storage position. The removable layer may be a sticker or other thin adhesive material, and/or may be made of paper and/or plastic material. Preferably, the removable layer 5 comprises a small tab or free surface 8, as depicted in
The spreading device of the present disclosure may, in whole or in part, be provided in different shapes.
An alternative embodiment is depicted in
In addition, the single, unitary component comprising the gripping or handling surfaces 3a, 3b and the filter 4 as depicted in
Application of the spreadable substance 6 to a surface will now be described based on the spreading device depicted in
With respect to application of the spreadable substance onto a desired surface, the filter 4 may be pressed against or placed near a surface so that the spreadable substance 6 is deposited onto such surface. With respect to the example of the spreadable substance 6 comprising butter, and the desired surface comprising a hot cob of corn, placing the filter 4 at the surface of the corn may cause the butter to at least partially melt and pass or flow through the filter and be deposited on the corn. Downward pressure on the container 2 by a user handling the gripping or handling surfaces 3a and 3b may assist with the depositing of the spreadable substance on the desired surface. Depending on the nature of the spreadable substance and the temperature of the desired surface or surrounding environment, it may or may not be necessary to apply pressure to the container 2 using the gripping or handling surfaces 3a and 3b, or otherwise, in order for the spreadable substance to pass through the filter 4.
Additionally, the spreading device may be handled in such a manner so as to spread the spreadable substance 6 on the desired surface. For example, the spreading device may be moved back and forth along the length of a cob of corn as shown in
After use, the spreading device can be configured into the storage position, which may facilitate sanitary, easy, mess-free and/or compact clean-up or disposal.
Although the spreading device depicted in
The above description regarding application of the spreadable substance 6 to a surface based on the spreading device depicted in
The spreading device of the present disclosure can be provided as either a single-spread or disposable device, or as a multiple-spread, re-fillable or re-usable device. The disposable spreading device may be made of one or more disposable materials, which may include one or more plastic or paper materials. Preferably, the disposable materials are biodegradable and/or recyclable. With respect to the re-usable spreading device, materials for the device's various components preferably may be selected so as to be sufficiently robust to withstand multiple uses and/or post-use cleanings.
Moreover, the filter 4 and/or the container 2 of a re-usable spreading device may be removably attached to the spreading device (either partially or fully removable in this regard) at the dispensing end or outlet of the container. Allowing such components to be removable enables re-filling the container 2 with a spreadable substance. In addition, allowing the container 2 to be removable enables access to the spreadable substance 6 in the event that a user prefers to apply the spreadable substance 6 to a surface using a knife or means that is other than through the filter 4. For example, the spreading device of
With respect to construction of the spreading device, injection molding may be used for one or more of the components described above. In addition, tack welding may be used where appropriate. For example, plastic tack welding may be used to secure one or more components together to form the spreading device 1. Particularly, plastic tack welding may be used to permanently secure the filter 4 to the gripping or handling surfaces 3a, 3b and/or the container 2 at the dispensing end or outlet of the container. Furthermore, it may be possible to use die cutting such as extrusion die cutting to form, for example, the gripping or handling surfaces or wings 3a, 3b of
With respect to the container 2 depicted in the various Figures, it has been depicted as being transparent. Such a transparent depiction may be possible in practice, and permits one reviewing the Figures to have a better view of surrounding structure and components than if the container 2 was depicted as non-transparent. Nevertheless, in actual practice it may be preferable and/or required pursuant to law, regulation or otherwise that the container be non-transparent or otherwise be such that the direct and/or diffused transmission of light through the container 2 does not exceed a certain threshold.
In some implementations of the present disclosure there is no grate or filter 4. For example where the spreadable substance 6 is applied to a delicate surface (e.g., a delicate pastry), the grate or filter 4 may damage the delicate surface. In these applications, it may be preferable to have the dispensing end open to the spreadable substance 6 when the spreading device 1 is in the spreading position, as depicted in
The spreading device of the present disclosure may also be provided with a toppings pouch 13, as depicted in
The spreading device of the present disclosure may also be provided with gripping or handling surfaces 3a, 3b that are perforated such that one or both of gripping or handling surfaces 3a, 3b may be converted or separated into functional tear-offs. As shown in
Alternatively, or additionally, the removable layer 5 may be perforated such that it may be converted or separated into functional tear-offs. As shown in
In particular, there may be instances where the material forming the container 2 may be prescribed pursuant to law, regulation or otherwise, such as a layered combination of aluminum and plastic for certain pharmaceutical creams. In this regard,
The spreading device 1 of the present disclosure may also be provided with an embedded electronic component, such as an RFID component, to track the shelf-life of the spreadable substance 6.
