The present invention relates to a clip scoop for dosing products and fastening to a flexible package.
Scoops have been used in various fields. For example, scoops have been used in fabric and home care products such as detergents and fabric enhancers for dosing the correct amount. Detergents are normally packed in a package such as cartons, hard plastic containers, and flexible packages. Flexible packages are useful in maintaining not only the freshness of the product stored, but also an aid in preventing moisture or air from entering the enclosed product. In addition, a flexible package normally uses less material and costs less than a comparable carton or hard plastic container.
For consumers to correctly dose a granular or particulate product, a scoop may be included with the product in the market. Such a scoop is generally included with the product in a package such as a carton and a hard plastic container but the container is not typically a flexible package because such flexible containers are typically larger bags in which the scoop may be easily lost or buried therein. Accordingly, it is sometimes easy for a consumer to misplace or lose a scoop between uses. It may be especially difficult to find a scoop in a package when the consumer is again ready to use it, because the scoop can be buried in the product in between uses. Also, when a consumer retrieves the scoop buried in the product, the product may adhere to the hand. The consumer may dislike this because it feels messy.
Accordingly, it is an objective of the present invention to provide a scoop which is easily fastened to the outside of a flexible package and/or which reduces messiness on the scoop. In addition, the use of a clip may provide a closure mechanism to keep the products in the flexible package fresh without having to change the flexible package itself or the flexible package material. Further, it is another objective of the present invention to provide a scoop whose handle securely connects to the bowl to resist bending when a large amount of solid is scooped.
The invention relates to a scoop having a bowl and a handle. The bowl has a bowl edge and a bowl width. The handle has a proximal handle edge connecting to the bowl edge. The handle has a distal handle edge opposite the proximal handle edge. The handle has a handle width. The handle has a clip with a clip base which connects the clip base to the distal handle edge. The clip protrudes from the distal handle edge toward the proximal handle edge. The clip has a free edge opposite the clip base. The handle width is at least about 50% of the bowl width.
The invention also relates to a kit having a flexible package containing a product therein, and a scoop as described above.
The inventors have surprisingly found that the clip can help the scoop be fastened to, for example, a flexible package. Without intending to be bound by a theory, the scoop of the present invention can be fastened to the external surface of the flexible package and the consumers may not need to return the scoop into the bag after use. Accordingly, the consumer can easily retrieve the scoop whenever it is needed with little chance of messiness. In addition, the orientation of the clip with respect to the scoop may reduce the amount that the scoop protrudes from the package. This is especially useful in cases where the package is stored in a high-traffic area to reduce the chance that the scoop is knocked off of the package, and/or in a crammed area where there is little overhead space. Further, the large handle width of the scoop may help the scoop to securely connect to the bowl and resist bending when a large amount of solid is scooped.
These and other objects, advantages and features of the invention will be more fully understood and appreciated by reference to the written specification and appended drawings.
The present invention is more readily understood by the attached non-limiting drawings, wherein:
The drawings herein are not necessarily drawn to scale.
The invention relates to a scoop having a bowl and a handle. The bowl has a bowl edge and a bowl width. The handle has a proximal handle edge connecting to the bowl edge, a distal handle edge opposite the proximal handle edge, and a handle width. The handle has a clip with a clip base which connects the clip base to the distal handle edge. The clip protrudes from the distal handle edge toward the proximal handle edge. The clip has a free edge opposite the clip base. The handle width is at least about 50% of the bowl width.
The handle, 30, has a proximal handle edge, 31. The handle, 30, has a distal handle edge, 32, opposite the proximal handle edge, 31. The handle, 30, has a first side arm, 33, and a second side arm, 34, typically but not always substantially parallel to the first side arm, 33, both of which extend perpendicular to the bowl, 21 in
The handle, 30, has a clip, 40 therein. The clip, 40, protrudes from the distal handle edge, 32, toward the proximal handle edge, 31. The clip, 40, has a clip base, 41, connecting to the handle, 30, and a free edge, 42. The clip, 40, typically has an undulation, 43, extending from the clip base, 41, toward the free edge, 42. The clip, 40, together with the handle side arms, 33 and 34, may serve as a fastening device when the scoop, 20, is fastened to a flexible package. Without intending to be bound by theory, it is believed that as the clip is integrated with the handle, the scoop does not need an extra material or device in order to fasten to the flexible package. As the clip protrudes from the distal handle edge toward the proximal handle edge and the bowl, when the scoop is fastened to the flexible package, the clip, the handle side arms and the bowl top edge may contact the external surface of the flexible package. It leads to increased stability of contact (see
In
The clip, 40, has a top surface, 46, and a bottom surface, 47, on the opposite side of the top surface, 46. The top surface, 46, is on the top side, T, of the scoop, 20 while the bottom surface, 47, is on the bottom side, B, of the scoop, 20. The convex, 52, is obliquely ascended in a top side direction from the clip base, 41. The concave, 56, is obliquely descended in a bottom side direction from the convex, 52. The free edge, 42, is again obliquely ascended in a top side direction from the concave, 56. On the bottom side, B, of the convex, 52, there is a reservoir space, 58.
The shape of the undulation, 43, on the top surface, 46, is also quite ergonomic in that it encourages a consumer to comfortably put his/her thumb on it and to hold the clip with the palm of the hand when the consumer dispenses the product using the scoop. This in turn provides a leverage point which makes scooping easier and reduces finger and wrist strain as compared to when a clip is held only by the fingertips. The shape of the bottom surface, 47, of the concave, 56, can serve as a fastening part to a flexible package when the scoop fastens the flexible package.
In
The bowl, 21, may have one or more stacking tab, 72, therein to allow easy stacking and unstacking of the scoops during manufacturing and/or storage. The stacking tab, 72, may be located inside the bowl, 21. The bowl may have up to about 8 stacking tabs, from about 1 to about 6 tabs, or from about 2 to about 4 stacking tabs. The stacking tab may be a small piece integrated with the bowl. The stacking tab should be small enough not interfere with the dispensing effort and may be located protruding from the bowl bottom. The stacking tab may have a height from about 3 mm to about 20 mm, from about 4 mm to about 15 mm, or from about 5 mm to about 10 mm. Without intending to be bound by theory, the stacking tab may prevent sticking to the next one when a plurality of scoops is stacked together. It is especially important in the manufacturing process of the scoops because the manufactured scoops can be stacked in the manufacturing line. A plurality of scoops may be stacked one after another when they are put into a package in the flexible package's filling process. The bottom of an upper scoop may be placed over the bottom of a lower scoop. The stacking tab located inside the bowl may prevent sticking of two scoops because the stacking tab may provide a barrier so that the bottoms may not be contacted to each other.
The overflow volume of the bowl, 21, is typically from about 5 mL to about 450 mL, from about 20 mL to about 320 mL, or from about 30 mL to about 150 mL. The overflow volume of the bowl, 21, can be measured by the maximum volume of water which can be stably held in the scoop. The perimeter of the bowl top edge, 29, of the scoop, 20, depicted in
In
The handle may also have a minimum handle width, WMIN, which is the smallest width of the handle. WMIN is located in between the proximal handle edge, 31, and the distal handle edge, 32. The minimum handle width, WMIN, may be more than about 75%, from about 75% to about 99%, or from about 80% to about 95% of the handle width, WH. Without intending to be limited by theory, it is believed that a handle with a narrower minimum handle width is more ergonomic and comfortable to hold than a handle whose width is constant along the entire length. However, as the minimum handle width, WMIN, gets too small, consumers may start to have structural issues which may lead to breaking, or unacceptable bending of the handle. Thus, the minimum handle width, WMIN, herein balances ergonomics and structural stability to achieve optimized results.
When a flexible package, see
The scoop, 20, may especially be fastened to a flexible package, 100, whose perimeter, 102, is rolled or folded over itself, at least once, twice, three times or four times in order to reclose the flexible package, 100. In
As to the free edge, 42, of the clip, 40, the flexibility of the clip, 40, makes it easy for a user to slide a part of a flexible package, 100, into the reservoir space, 58, between the clip, 40, and the handle, 30. In
In an embodiment herein, the clip base, 41, may be reinforced to prevent or reduce breakage at this point. Since the clip, 40, flexes the most at the clip base, 41, this is where much of the stress and strain is focused during use and storage. Therefore, the clip base may be reinforced, by, for example, making this portion thicker, of a different material (e.g., more elastic, more rigid, etc. as desired), making this portion thinner, and/or adding additional structural elements to address the stresses focused on this point. In an embodiment herein, the clip base, 41, is from about 1% to about 100% thicker, or from about 5% to about 50%, or from about 7% to about 25% thicker than the adjoining portion of the clip, 40. In an embodiment herein, the clip base, 41, is from about 1% to about 100% thicker, or from about 5% to about 50%, or from about 7% to about 25% thicker than the adjoining portion of handle, 30.
As described above, the grippers may be located on either the clip or on the handle as desired, so that the grippers can contact the flexible bag and keep it from slippage.
The friction between the scoop and the flexible package may be increased by increasing the coefficient of friction therebetween, such as by modifying the scoop's surface finish and or by modifying the surface material of the clip and/or the handle. In order to increase the friction, at least a part of the flexible package may be coated by a material having a higher coefficient of friction than the unmodified flexible package, such as by adding rubber, a paraffin, a cellophane, etc. and may be added by a variety of processes known in the plastic-making art. In an embodiment herein, the gripper is made from rubber which is co-injection-molded into the scoop itself.
The surface material and/or the coating material may be selected from the group consisting of polyvinyl, polypropylene, polycarbonate, polystyrene and polyesters.
As described above, the scoop herein may be fastened to a flexible package, and especially can maintain the rolled or folded shape of the perimeter of a flexible package. After opening the flexible package, the scoop can be fastened to the external surface of the flexible package. Thus, the consumers can take the scoop off the package and use it easily without putting the hand into the flexible package for the scoop inside.
The clip may have a length from the clip base to the free edge, where the length is from about 2 cm to about 10 cm, from about 3 cm to about 9 cm, or from about 4 cm to about 8 cm.
The scoop herein may be injection molded, which molding has the advantages of providing a finished product which is both durable and sturdy.
The present invention further relates to a kit containing the scoop as described above and a flexible package. A consumer can use the scoop herein together with a flexible package. After opening the flexible package, the perimeter needs to be closed, e.g., by folding or rolling. The folded or rolled perimeter also needs fastening so that the product inside may not contact the external moisture or air. For the purpose, the scoop herein can be used to fasten the perimeter. When the kit herein is subject to distribution (e.g., retail stores), the scoop may be contained inside the flexible package. Otherwise, the scoop may be attached to the external surface of the flexible package.
Additionally or alternatively, the flexible package may have a zipper closure device for opening. The zipper closure device can be opened or closed repeatedly without damaging the flexible package. When the flexible package is reclosed by the zipper closure device, the flexible package can be completely closed and shut out of the external environment. With a zipper closure device, it may be possible to protect the product contained in the package from moisture or air without folding or rolling the package.
The scoop herein may be formed of any suitable kind of material, typically a plastic material such as polyethylene, polypropylene, polystyrene, polyethylene terephthrate, polyester, polychlorovinyl, and a combination thereof, or polyethylene, polypropylene and a combination thereof.
The flexible package may have a thickness from about 0.01 mm to about 5 mm, from about 0.02 mm to about 4 mm, or from about 0.03 mm to about 3 mm. The material used for the flexible package may include, but not limited to, a thermoplastic material (e.g., polyethylene, polypropylene, polystyrene, polyester, polychlorovinyl, etc.), a paper material (e.g., paper, cardboard. etc.), a rubber material, and the like. The flexible package may contain a product selected from the group consisting of a solid product, a liquid product and/or a gel product. The product herein may be a unitized dose product, such as a tablet, a geltab, a dissolvable pouch, and/or a combination thereof. In an embodiment herein the product is a solid product, especially a granular product. The product may include, e.g., a fabric detergent, a fabric enhancer, a hard surface detergent, a bleach, a coffee bean, a coffee powder, a milk powder, a pet food, etc.
The scoop herein may be transparent, translucent or opaque. The scoop herein may contain at least one color, and may contain from two to five colors. Such colors may be indicate different parts of the scoop, different materials, indicate origin or branding, be purely for aesthetic reasons, etc.
