    Description

    FIELD OF THE INVENTION



    [0001] The present invention relates to a dispenser for dispensing food dressing that prevents the food dressing from dripping from the dispenser.

    BACKGROUND OF THE INVENTION



    [0002] Dispensers suitable for dispensing edible oils are known in the art. Typically, such dispensers are decorative and comprise a container for holding the oil and a spout through which the oil can be dispensed from the container.

    [0003] A deficiency with existing oil dispensers is that after pouring they typically drip or leave a trail of oil running down the outer edge of the dispenser. More specifically, after pouring, once the user has returned the dispenser to an upright position, a trail of oil is left to drip down the outside edge of the spout. After numerous uses, a sufficient amount of oil has dripped down the edge of the spout to cause the body of the container to be covered in oil. This not only results in a waste of oil (which can be quite expensive depending on the quality of the oil) but also creates an unpleasant greasy coating on the outside of the dispenser which can cause a user's hands and fingers to become greasy and sticky.

    [0004] In view of the above, it is clear that there is a need in the industry for an improved food dressing dispenser that alleviates at least in part the deficiencies of existing dispensers.
    A dispenser comprising all the technical features of the preamble of claim 1 is furthermore known from the document US 5511700 A1.

    SUMMARY OF THE INVENTION



    [0005] In accordance with a broad aspect, the present invention provides a dispenser for food dressing, as defined by appended claim 1.

    [0006] This and other aspects and features of the present invention will now become apparent to those of ordinary skill in the art upon review of the following description of embodiments of the invention in conjunction with the accompanying figures.

    [0008] In the drawings, embodiments of the invention are illustrated by way of example. It is to be expressly understood that the description and drawings are only for purposes of illustration and as an aid to understanding, and are not intended to be a definition of the limits of the invention.

    DETAILED DESCRIPTION OF EMBODIMENTS



    [0009] To facilitate the description, any reference numeral designating an element in one figure will designate the same element if used in any other figures. In describing the embodiments, specific terminology is resorted to for the sake of clarity but the invention is not intended to be limited to the specific terms so selected, and it is understood that each specific term comprises all equivalents.

    [0010] Unless otherwise indicated, the drawings are intended to be read together with the specification, and are to be considered a portion of the entire written description of this invention. As used in the following description, the terms "horizontal", "vertical", "left", "right", "up", "down" and the like, as well as adjectival and adverbial derivatives thereof (e.g., "horizontally", "rightwardly", "upwardly", "radially", etc.), simply refer to the orientation of the illustrated structure. Similarly, the terms "inwardly," "outwardly" and "radially" generally refer to the orientation of a surface relative to its axis of elongation, or axis of rotation, as appropriate.

    [0011] In the figures, a dispenser 10 for food dressing in accordance with a non-limiting embodiment of the present invention is shown. The dispenser 10 is suitable for dispensing food dressings, such as salad dressings, olive oil, oil and vinegar, oil mixed with vinegar and spices, food marinades, or any other type of edible food dressing.

    [0012] The dispenser 10 comprises a cap 12 and a container 14 that together extend along a longitudinal axis identified by reference numeral 8 in Figure 2. The container 14 further comprises a bottom wall 28 and a peripheral wall 30 that define an internal space 18 for receiving a volume of food dressing, and a rim 26 that defines an opening 27 such that food dressing can exit via the opening 27. The container 14 may be made of transparent plastic, glass, ceramic or stainless steel, among other possibilities.

    [0013] The cap 12 comprises an attachment portion 34 for attaching the cap 12 to the container 14 for at least partially covering the opening 27. In the embodiment shown, the attachment portion 34 of the cap 12 comprises internal threads 36 for engaging with corresponding external threads 32 on the rim 26 of the container 14. In this manner, the cap 12 and container 14 can be removable attached together by screwing and unscrewing the cap 12 onto the container 14. Although in the embodiment depicted, the rim 26 comprises external threads 32 and the attachment portion 34 of the cap 12 comprises internal threads 36, the thread arrangement could be reversed such that it is the rim 26 that comprises the internal threads and the cap 12 that comprises the external threads. In addition, instead of comprising corresponding threads, the cap 12 and the container 14 could be attachable to one another via a friction fit or a snap-fit arrangement, among other possibilities.

    [0014] As best shown in Figure 4, the dispenser 10 further comprises a peripheral ring 38 that is positioned between the cap 12 and the container 14 when the cap 12 and the container 14 are attached together. The peripheral ring 38 has a portion that is located within the opening 27 and which defines an opening 39 for allowing flow of the food dressing through the openings 27, 29. The peripheral ring 38 also has a shoulder 40 projecting outwardly at its top end and which is located above the rim 26. A sealing member 42, which can be an O-ring or gasket, is positioned between the lower surface of the shoulder 40 of the peripheral ring 38 and the upper surface of the rim 26 in order to create a seal between the peripheral ring 38 and the container 14.

    [0015] The cap 12 further comprises a peripheral wall 46 and a top wall 48 for forming an external shell. The external shell of the cap 12 may be made of aluminum, plastic or stainless steel, among other possible materials. Although the peripheral wall 46 and the top wall 48 are shown as being separate components in the figures, it should be appreciated that the peripheral wall 46 and the top wall 48 could be integrally formed via a molding process, for example. The cap 12 further comprises an aperture 47 in the peripheral wall 46, within which a spout 16 can be at least partially mounted. The spout 16 can be made of a material such as plastic or stainless steel, among other possibilities. The spout 16 has a distal end 17 and a proximal end 19 that are angled, such that when the spout 16 is inserted within the aperture 47 of the peripheral wall 46, the distal end 17 of the spout 16 form a plane that is generally parallel to the longitudinal axis 8 of the dispenser 10.

    [0016] The peripheral wall 46 and the top wall 48 define an internal space 50 within which an internal member 20 is located.

    [0017] As shown in Figures 4 to 6, the internal member 20 comprises a tube 22 that extends between a first end portion 52 having a first opening 520 facing the internal space 18 (when the cap 12 is attached to the container 14) and a second end portion 54 having a distal end 54E with a second opening 540 facing the atmosphere such that the tube 62 defines a passage 53 between the first and second openings 520, 540 for allowing fluid communication between the internal space 18 and the atmosphere via the passage 53 when the dispenser 10 is tilted by a user.

    [0018] As shown in Figure 6, the tube 22 of the internal member 20 has a length L1 with a first section 70 extending from the first end portion 52 and having a length L2 and a second section 72 ending at the distal end 54E and having a length L3.

    [0019] The length l2 of the first section 70 may be longer than the length l3 of the second section 72. More specifically, the length l2 of the first section 70 forms between 55-70% of the overall length l1 of the tube 22, and the length l3 of the second section 72 forms between 30-45% of the overall length l1, For example, the length l1 of the tube may be in the order of 1.80 to 2.10 inches, the length l2 of the first section 70 may be in the order of 2.79 cm (1.10 inches) to 3.30 cm (1.30 inches) and the length l3 of the second section may be in the order of 1.65 cm (0.65 inches) to 2.16 cm (0.85 inches).

    [0020] In accordance with an embodiment of the invention, the passage 53 along the first section 70 has an internal taper of between 1.5° and 5° and the second section 72 extends along a curve such that the distal end 54E is generally parallel to the longitudinal axis 8 (as best shown in Figure 4). Referring to Figure 6, the internal wall defining the passage 53 along the first section 70 extends along a line that defines an angle θ2 with a horizontal line. The angle θ2 may range between 85° and 88.5°.

    [0021] In accordance with another embodiment, the passage 53 along the section 72 may also have a tapering shape and the passage 53 may also have a greater internal taper than the passage 53 along the second section 72. For example, the passage 53 along the second section 72 may have an internal taper of between 0.01° and 1.5° and its internal wall, when seen in Figure 6, may extend along a line that defines an angle θ3 with a horizontal line. The angle θ3 may range between 89.99° and 88.5°. It is understood that as long as the angle θ3 is less than 90°, the passage 53 along the second section 72 has an internal taper.

    [0022] In accordance with the present invention, the diameter of the passage 53 of the tube 22 may reduce gradually from the first end portion 52 to the second end portion 54. More specifically, the passage 53 has a first diameter d1 at the first end portion 52 of the first section 70 and the passage 53 has a second diameter d2 at the second end portion 54 of the second section 72 where there is a ratio between the second diameter d2 and the first diameter d1 of between 0.55 and 0.75 as a result of the internal tapering of the first and second sections 70, 72. The passage 53 also has an intermediate (third) diameter d3 at the entry of the second section 72 where the ratio between third diameter d3 and the first diameter d1 is between 0.6 and 0.75 and the ratio between the second diameter d2 and the third diameter d3 is between 0.91 and 0.99.

    [0023] For the sake of example, the first diameter d1 at the entry of the second section 70 (near the first end portion 52) may be between 0.724 cm (0.285 inches) and 0.749 cm (0.295 inches) (advantageously around 0.736 cm (0.290 inches)), the third (intermediate) diameter d3 at the entry to the second section 72 may be between 0.495 cm (0.195 inches) and 0.520 cm (0.205 inches) (advantageously around 0.508 cm (0.200 inches)) and the second diameter d2 at the exit of the second section 72 (distal end 54E) may be between of 0.470 cm (0.185 inches) and 0.495 cm (0.195 inches) (advantageously around 0.483 cm (0.190 inches)). As such, the diameter of the passage 53 of the tube 22 may reduce by 60% to 85% between the first end portion 52 and the second end portion 54.

    [0024] It should be appreciated that the internal member 20 is removable from the cap 12, such that it can be taken out of the cap 12 to be cleaned or replaced. The internal member 20 can be made of an elastomeric material, such as food grade silicone, among other possible materials.

    [0025] The internal member 20 comprises the tube 22 having the first end portion 52, the second end portion 54 and the passage 53 for pouring the food dressing out of the second end portion 54 that is open to the atmosphere. The internal member 20 further comprises an aeration tube 24 for enabling air from the atmosphere to enter the internal space 18. The aeration tube 24 comprises a first end 60 defining a first opening 62 facing the internal space 18 of the container 14 and a second end 64 defining a second opening 66 facing the internal space 50 of the external shell of the cap 12. The aeration tube 24 thus defines an air passage 67 between the internal space 18 of the container and the internal space 50 of the external shell that, in use, when food dressing is dispensed through the passage 53 of the tube 22, allows air to penetrate into the internal space 18 of the container 14 in order to replace the volume of food dressing being dispensed out. As a result, food dressing can dispense out through the passage 53 of the tube 22 smoothly, without the risk of bubbles interrupting the flow.

    [0026] The internal member 20 further comprises a central wall portion 56 and an outer rim 58. The central wall portion 56 forms a type of cap and the outer rim 58 is pressed against the shoulder 40 when the cap 12 is attached to the container 14 for preventing the food dressing within the internal space 18.

    [0027] When the cap 12 has been attached to the container 14, an internal peripheral shoulder 53 of the cap 12 press against the outer rim 58 that is pushed against the upper surface of the shoulder 40 such that the outer rim 58 sealingly engages with the shoulder 40 in order to create a seal between the member 20 and the peripheral ring 38 such that food dressing can only flow through the opening 27 of the container 14, the opening 29 of the peripheral ring 38, enter in the passage 53 of the tube 22, flow in the passage 53 and exit the tube 22 at the upper end portion 54 (through the spout 16) when the dispenser 10 is tilted.

    [0028] As indicated previously, the dispenser also has a sealing member 42 in order to create a seal between the peripheral ring 38 and the container 14. The sealing member 42 and the pressing of the outer rim 58 against the shoulder 40 therefore prevent the food dressing from leaking between the container 14 and the peripheral ring 38 and between the peripheral ring 38 and the internal member 20. In the case where the dispenser 10 does not include the peripheral ring 38, the outer rim 58 of the internal member 20 would be pressed on the upper surface of the rim 26 of the container 14 so as to sealingly engage the rim 26 in order to create a seal between the internal member 20 and the container 14.

    [0029] As best shown in Figures 4 and 6, the distal end 54E of the second end portion 54 has an angle θ1 of between approximately 40° and 50°, and preferably 45°, such that the distal end 54E is generally parallel to the longitudinal axis 8 when the distal end 54E is mounted around the proximal end 19 of the spout 16. The portion of the second end portion 54 that engages the spout 16 and the spout 16 both extend along a line defining an angle θ4 of approximately 40° to 50° about the a line parallel to the longitudinal axis 8. The second end portion 54 may engage with the spout 16 by being placed around the proximal end 19 of the spout 16, or by being placed within the passage of the spout 16. The engagement between the spout 16 and the second end portion 54 of the tube is generally created via a friction fit.

    [0030] The functioning of the dispenser 10 according to the present invention will now be described in more detail with respect to Figures 7 through 10. In Figure 7, the dispenser 10 has been tilted downwardly in a direction indicated by arrow 80 into a pouring position. In this pouring position, the food dressing that is stored within the internal space 18 can be pour from the internal space 18, flow through the openings 27, 39, flow through the passage 53 along the first and second sections 70, 72 of the tube 22 and is poured out of the second end portion 54 (or spout 16 when a spout is located within the second end portion 54).

    [0031] In Figures 8 and 9, the dispenser 10 is tilted in substantially the reverse direction indicated by arrows 82, in order to move the dispenser 10 back into an upright position. As the dispenser 10 is tilted in this direction, the flow of the food dressing from the second end portion 54 (spout 16) is interrupted (as depicted in Figure 8) and the food dressing starts to flow back through the passage 53 into the internal space 18.

    [0032] Finally, in Figure 10, once the dispenser 10 is back in the upright position, any food dressing remaining in the passage 53 flows back into the internal space 18.

    [0033] As depicted in Figures 9 and 10, as the dispenser 10 is moved back into the upright position, the food dressing contained in the passage 53 does not drip down out of the second end portion (spout 16) or leave a trail running down the outside surface of the cap 12. Instead, there is a relatively clean interruption of the flow of food dressing that is poured out of the second end portion 54 (spout 16), such that the remaining food dressing is drawn back into the internal space 18. As a result, the dispenser 10 is a substantially drip-free pouring dispenser.

    [0034] In a venturi tube, the fluid, the food dressing in this case, that flows within the narrower, more constricted area of the tube passage flows at a higher velocity and a lower pressure than the fluid that flows within the wider, less constricted area of the tube passage. Without wishing to be bound by the following explanations, it is believed that due to the different internal tapers of the passage 53 along the first and second sections 70, 72 of the tube 22, the forces on the food dressing that result from the shape and configuration of the tube 22 and passage 53, cause the food dressing remaining in the passage 53 at the second section 72 to flow back into the internal space 18 without dripping from the second end portion 54 (or spout 16) when the dispenser 10 is moved back by the user into an upright position.
    More particularly, the tapering shape of the passage 53 along the first section 70 of the tube 22 creates a type of venturi tube effect at the entry of the second section 72 when the food dressing is poured out. The area of the passage 53 near the entry of the second section 72 is therefore at a lower pressure. When the dispenser 10 is moved back into an upright position after pouring, the pressure differential exerted on the food dressing as a result of the tapering shape of the passage 53 along the first section 70 causes the food dressing remaining in the passage 53 at the second section 72, which is still at that point at a lower pressure near the entry of the second section 72, to flow back into the internal space 18 without dripping from the second end portion 54 (or spout 16) as the dispenser 10 is returned to an upright position. While the tube 22 has a passage 53 with a first internal taper along the first section 70 and a second internal taper along the second section 72, it is believed that a tube with a curved distal end portion with a end face parallel to the longitudinal axis of the dispenser and a passage with an internal taper along the length of the tube would create forces on the food dressing causing the food dressing remaining in the passage to flow back into the internal space of the container without dripping from the distal end portion when the dispenser is moved back by the user into an upright position. Food dressings such as olive oil have relatively long chains of carbon molecules, which create relatively strong intermolecular forces. Many food dressings further comprise high viscosities. For example, the viscosity of olive oil is in the order of 84 cPoise. The strong intermolecular forces, together with the narrowing of the internal diameter of the passage 53 of the tube 22 may further help to draw the food dressing remaining in the passage 53 back into the internal space 18 of the container 14 once the pouring of the food dressing is complete and the user moves back the dispenser 10 into the upright position.

    [0035] Moreover, because the second section 72 extends along a curve such that the distal end 54E is generally parallel to the longitudinal axis 8, and because of the capillary action between the food dressing and the internal wall of the passage 53 of the tube 22, which is made of food grade silicone, the food dressing is caused to be pulled back into the tube 22, as opposed to dripping out of the second end portion 54 (spout 16). Also, when the user stops pouring and moves back the dispenser 10 into the upright position, air bubbles can be present in the food dressing at the upper surface of the internal wall of the passage 53 along the second section 72 and these air bubbles may facilitate to draw the food dressing back into the internal space 18 of the container 14.

    [0036] Furthermore, providing that air bubbles are present in the food dressing remaining in the passage 53 at the second section 72, and providing that food dressing is separated in several drops due to the viscosity of the food dressing and the higher pressure in the passage 53 at the section 70, these air bubbles and this separation of the food dressing in several drops may facilitate to draw of any remaining drops in the passage 53 at the second section 72 back into the internal space 18 of the container 14.

    [0037] Although the present invention has been described in considerable detail with reference to certain preferred embodiments thereof, variations and refinements are possible without departing from the scope of the invention as defined by the appended claims.
