Description

FIELD OF INVENTION

The present invention relates to utensils that can store and dispense a liquid or solid. The present invention particularly but not exclusively is directed to dispensing spoons. Reference to dispensing spoons in the body of the specification is by way of example only and the present invention is not limited to a dispensing spoon. The term utensil within the specification includes a spoon, fork, knife, stirrer and any suitable instrument or implement.

BACKGROUND OF THE INVENTION

Spoons that can store and dispense ingredients have been developed to provide convenience and an alternative to the awkwardness of using separate items. The developed dispensing spoons dispense ingredients from the bowl of the spoon. The ingredients are stored in the spoon handle (such as U.S. Pat. No. 6,675,482, U.S. Pat. No. 5,491,895 and U.S. Pat. No. 5,154,318) or within the bowl of the spoon (such as U.S. Pat. No. 3,911,578, U.S. Pat. No. 3,946,652 and U.S. Pat. No. 4,338,338). These dispensing spoons suffer one or more of the following disadvantages including being expensive to manufacture, not suitable for reuse, unable to reclose the container portion and aesthetically unappealing.

OBJECT OF THE INVENTION

It is an object of the present invention to provide an alternative dispensing utensil that overcomes at least in part one or more of the above mentioned disadvantages.

SUMMARY OF THE INVENTION

A first aspect of the present invention provides a dispensing utensil comprising:

• • a handle portion;
  • an implement portion;
  • a cavity for storing dispensable contents, the cavity defined by a first wall means and a second wall means closing the cavity; wherein a first portion of the first wall means is openable about a hinge formed by the second wall means, thereby allowing the contents to be dispensed.

Preferably the second wall means is a pliable to wall, and preferably the second wall means is paper, film, foil or a laminate including paper, film or foil. Preferably the first wall means is a thin walled plastic shell.

In a preferred embodiment the first wall means has integrally formed first and second portions, and a failure zone between the first and second portions.

Advantageously, the dispensing utensil is economic to manufacture and fill. The cavity defined by the first wall means may have a relatively large area and thus may be top filled with contents and subsequently sealed by the second wall means much more efficiently than end filling arrangements. End filling of a tubular cavity is less efficient as the small end opening provides a limited filling area. Furthermore, provision of a tubular cavity requires a thick walled structure in order that the utensil has sufficient strength. The combination of these factors makes end filling expensive. In contrast, a dispensing utensil according to the present invention may be formed from a thin walled shell having a relatively large area, be filled very quickly and subsequently closed or sealed by a pliable top wall. Advantageously, empty shells may be nested for storage and transport, reducing the space required for transport and storage. This manufacturing process has reduced material costs and reduced process time and hence may be highly economical.

A further advantage of the present invention is its ease of use. The first portion of the first wall means is openable about the hinge formed by the second wall means. This allows for easy one-handed operation and also retains the first portion on the utensil, which may reduce littering etc.

The failure zone between the first and second portions could be a thinner area of material, or could be weakened by other failure means such as perforations. Advantageously, this also contributes to increased tamper-proofing of the utensil, as it is readily apparent that the utensil has been opened.

In one embodiment the first portion of the first wall means is distal from the implement portion. This advantageously allows for some contents to be dispensed, and for the tool to then be used without dispensing further contents (e.g., to stir a half portion of sugar in coffee).

In another embodiment the first portion of the first wall means is a proximal of the implement portion. This advantageously allows for contents to be dispensed and the tool immediately to be used without reversing (e.g., to stir a full portion of sugar in coffee).

Preferably, an embodiment of the invention further includes a second cavity for storing dispensable contents and preferably dispensing of contents from the second cavity is independently operable in the same manner as the first cavity. This advantageously allows for provision of complementary contents such as pepper and salt, in separately controlled portions.

Preferably, the first portion of the first wall means is re-closable, optionally by a friction fit. Advantageously, this prevents spillage and allows for any remaining contents to be used at a later time.

Preferably, the first portion of the first wall means has a thumb rest, increasing ease of use.

In a preferred embodiment, the second wall means is printed with one or more of: a measuring guide, product information, instructional information, graphics, branding or advertising. Preferably, the second wall means includes a window portion allowing the contents to be viewed, and preferably the first and/or second wall means may be deformed to control dispensing of contents. This advantageously allows for flexible and easy portion control when dispensing contents.

Preferably, the handle portion and implement portion are integrally formed.

A second aspect of the present invention provides a dispensing utensil comprising:

• • a handle portion;
  • an implement portion;
  • a cavity for storing dispensable contents;
  • a pliable top wall closing the cavity; wherein a lid connected to the top wall is openable about a hinge means formed by the top wall, thereby allowing the contents to be dispensed.

A third aspect of the present invention provides a dispensing utensil shell comprising:

• • a handle portion;
  • an implement portion;
  • a cavity for storing dispensable contents, the cavity defined by a first wall means; wherein the first wall means is adapted to co-operate with a second wall means for closing the cavity; wherein the first wall means has integrally formed first and second portions, and a failure zone between the first and second portions, whereby in use, a first portion of the first wall means is openable about a hinge formed by the second wall means, thereby allowing the contents to be dispensed. Advantageously, the shell may be nested for storage and transport, prior to being filled with contents and closed or sealed.

Tools (implements) which may be incorporated in the dispensing utensil include (but are not limited to) stirrers, mixing paddles, spoons, forks, knifes, chopsticks, drinking straws, brushes (of many types), tooth picks, floss picks, mops, tongs, tweezers, razors, trowels and spades, spatulas and combs.

The dispensing utensil's contents are preferably synergistically paired with the tool for maximum effectiveness. Some non-limiting examples may include sugar or energy drink concentrate in a spoon or stirrer, wasabi and soy sauce in chopsticks, cocktail stirrer and alcohol shot, two-part glue with a stirrer/mixing spatula, touch-up or children's paint with a brush, toothpaste with toothbrush, dental floss pick and mouthwash, medicament or ointment such as cold-sore cream with applicator pad/brush, cooking oil in a spatula or barbeque tongs, salad dressing in salad-serving spoon, tweezers with antiseptic ointment, brush with marinade sauce, razor with shaving creme, garden trowel or spade with seeds, paint stirrer with colour tint, washing brush with detergent, spatula with putty or gap filler, mop with disinfectant or floor cleanser, comb or brush with hair treatment or styling product.

Contents which may conveniently be dispensed from a dispensing utensil according to the present invention include, but are not limited to, the following whether in powdered, granulated, liquid or other forms.

DESCRIPTION OF PREFERRED EMBODIMENT

With reference to FIGS. 1 to 12, there is shown a single chamber dispensing spoon (utensil) 10 having a handle 11 integral with a spoon bowl (implement portion) 12 to form a single unit. The handle 11 has opposing side walls (first wall means) 13, 14 which form a substantially U-shaped elongate chamber (cavity) 15. The side walls 13, 14 are substantially the same height and each have a flat top surface 16, 17 respectively. As the handle 11 forms a U-shaped elongate chamber 15 to hold dispensable items (contents), it may be made of plastic material with relatively thin walls. In contrast, the surrounding walls of tubular shaped handles are comparatively thicker by design than the walls of the handle 11.

A pliable top wall (second wall means) 19 is fixable to the flat top surface 16, 17 surrounding the elongate chamber 15. The pliable top wall 19 closes chamber 15 and may be heat sealed or induction sealed where the top wall is film or foil respectively. In the present embodiment the pliable top wall 19 is made of foil. The pliable top wall 19 is fixed to the flat top surface 16, 17 after the dispensable items (contents) have filled the elongate chamber 15. The fixing of the pliable top wall 19 to the flat top surface 16, 17 after the chamber has been filled with dispensable items avoids the problems associated with the end filling of dispensable items in preformed tubular type containers. In this way a dispensing utensil is produced by a three stage process involving the formation of a chamber, filling the chamber with dispensable items and sealing the chamber with a pliable top wall.

There is a lid portion (first portion) 20 formed as part of an end portion of side walls 13, 14 of handle 11. In this embodiment, the lid portion 20 is at the opposite (distal) end of the utensil from the spoon bowl 12. The lid portion 20 is surrounded by a thin section (failure zone) 21 which defines the sides of the lid 22 when it is opened. The failure zone 21 is located between the first portion 20 and a second portion 26 of first wall means 13, 14. The lid 22 is formed from the lid portion 20 when pressure is applied and the surrounding thin section 21 is torn and the lid 22 is pressed outward.

The lid portion 20 including lid 22 is shaped to allow a thumb to rest against it and open it with applied pressure. Advantageously, one-handed operation is possible. The applied pressure tears the thin section 21, causing the lid 22 to open about a hinge 19′ formed by the pliable foil top wall 19. The lid portion 20 has support protrusions (thumb rest) 23 to provide a grip for the thumb. The lid portion 20 also has a friction-fit protrusion 24 enabling the lid 22 to reclose. A dispensing spoon in the open position is shown in FIG. 13.

The pliable top wall 19 has a flat and relatively level upper surface 25 to provide an aesthetically pleasing spoon similar to conventional spoons and provide a comfortable grip for the user. The flat and relatively level upper surface 25 of the pliable top wall 19 is maintained irrespective of the length, depth and width dimensions of the chamber 15. Handles with different capacities of holding dispensable material is shown in FIG. 32 where the utensil shown in (a) represents a single serve, (b) represents a double serve and (c) represents a quad serve.

The pliable top wall 19 provides an upper surface 25 on which information, branding, graphics and advertising can be displayed. The information that may be displayed may include dietary information, instructional information, contents information and dispensing information. For example, the top surface 25 may display dispensing information in the form of a ruler indicating where a person may press in order to dispense a particular part serve. Advantageously, the pliable top wall 19 and/or the first wall means 13, 14, may be deformed or pressed to control dispensing of contents.

In another embodiment shown in FIGS. 13 to 17, the utensil 30 has an upper wall 31 fixed to the elongate body 32 of handle 33. The upper wall 31 has a clear window section 34 through which a person may view the dispensable contents. Other features of the embodiment shown in FIGS. 13 to 17 are similar to those described above, in which the lid may be opened about hinge 31′.

A further embodiment is shown in FIGS. 18 to 24. This embodiment shows a utensil 40 with a large handle 41 providing a larger chamber 42 to store an increased amount of dispensable items to form a double serve dispensing utensil 40. The dimensions of the double serve dispensing utensil 40 are substantially proportional but larger than the dimensions of the single serve utensil 10 shown in FIGS. 1 to 12.

Another embodiment of the dispensing utensil is shown in FIGS. 25 to 31. The dispensing utensil 50 shown in these Figures is substantially elongate compared to the single and double serve dispensing utensils 10, 40 respectively. The dispensing utensil 50 has a comparatively larger chamber to store a larger amount of dispensing items and forms a quad serve dispensing utensil.

A further embodiment of the dispensing utensil is shown in FIG. 32(d) and FIGS. 33 to 44. In this embodiment the dispensing utensil 60 has a handle 61 with an internal rib 62 dividing a first cavity 63 from a second cavity 64. The two chambers or cavities 63, 64 are able to store different items. The dispensing utensil 60 has two lids 65, 66 operatively associated with chambers 63, 64 respectively. The lids 65, 66 are formed in a similar manner to the single chamber utensil 10 as described above. Each lid 65, 66 may be opened separately so that the contents in the chambers 63, 64 respectively may be dispensed separately and without contamination from the other chamber. In order to achieve separate openings of the lids 65, 66, the pliable top wall 67 has an end split 68 separating each lid 65, 66.

Other embodiments may have additional chambers to accommodate different dispensable items.

Furthermore, other embodiments may have a stirring rod, knife blade or fork prongs instead of a spoon bowl. With the various embodiments the stored dispensable items preferably relate to the particular dispensing utensil. By way of example, a dispensing knife or dispensing fork may have stored salt, pepper or other condiments while a dispensing spoon may contain sugar, coffee, whitener, powdered chocolate or another suitable additive for a drink.

The preferred embodiment of the present invention provides the advantage that the utensil can be manufactured, filled and assembled relatively more easily and cheaply than tube-shaped dispensing utensils, as well as having increased functionality and ease of use for the consumer.

It will of course be realised that while the foregoing has been given by way of illustrative example of this invention, all such and other modifications and variations thereto as would be apparent to persons skilled in the art are deemed to fall within the broad scope and ambit of this invention as is herein set forth.

Throughout the description and claims this specification the word “comprise” and variations of that word such as “comprises” and “comprising”, are not intended to exclude other additives, components, integers or steps.
