ORAL CARE ARTICLE COMPRISING A CONTAINER
An oral article comprising a six sided carton (suitable for containing a tube of dentifrice) having a front-top flap that is unfolded open along a line of weakness, wherein at least a portion of the line of weakness includes a ½ cut line of weakness on the top side of the carton.
The present invention is directed to an oral care article comprising a carton that is easy to open and has premium look.
BACKGROUND OF THE INVENTIONRectangular cartons containing a tube of toothpaste are ubiquitous. Users often open the carton to access the tube of toothpaste from either side (i.e., smallest dimension of the sides). Users report being frustrated in opening a side panel and further frustrated by sometimes having to shake the carton to jostle the tube free from the interior of the carton (given the relatively small opening that is provided by the side panel). There is a need for users to more easily access the tube of toothpaste contained in the carton. Moreover, there is a need by manufacturers to connote a premium package and opening experience to users to provide a premium product and experience.
SUMMARY OF THE INVENTIONThe present invention is based on the surprising discovery that a rectangular six sided cartons, suitable for containing a tube of toothpaste, can be engineered with a front/top flap that is capable of being unfolded open to expose the tube of toothpaste, which in turn, can be easily removed from the interior of the carton. The user grasps the finger tab of the front-top flap and separates the flap along a line of weakness. By having at least a portion of the line of weakness as a ½ cut, a relatively smooth exterior surface is provided (by which graphics and branding, etc., can be applied). The carton provides a premium impression and experience to users.
An advantage of the front-top flap is that the user can open the flap and expose a large enough area such that the tube of toothpaste can be easily removed without obstruction from the container.
Another advantage is the inside surface of the front-top flap can be provided with messaging so the manufacturer can be given another touch point to communicate with the user (that otherwise is not available in classic cartons (containing tubes of toothpaste)).
Another advantage is providing a line of weakness in the top side of the container, wherein at least a portion of the line of weakness is a ½ cut, so as to provide a high quality view of the packaging including branding or advertising (that comparatively may not be as evident from a line of weakness comprising perforations).
Another advantage is to provide a carton opening experience that allows the user to open the front-top flap across two adjoining sides of the package (i.e., the front and top sides) without the flap “hanging up” or otherwise becoming impeded (or other requiring unreasonable force by the user).
Another advantage is to provide a carton with enough of an opening (upon the front-top being opened) so that the user is able to remove the tube of dentifrice from inside cavity of the carton without the edges of the carton (around the opening) significantly impeding the removal of the tube.
Another advantage is providing the impression of a high quality carton to the user by not visually exposing any portion of the flaps (constituting the side panels) through the opening created by the opened front/top panel.
One aspect of the invention provides for an oral care article comprising a six sided rectangular carton capable of containing a tube of dentifrice, wherein the carton comprises:
(a) a front side, an adjoining top side, a back side opposing the front side, and a longitudinal axis passing along the length of the carton;
(b) a top side/back side edge is located at the interface of the top side and back side, wherein the top side/back side edge comprises a non-foldable edge and an adjacent foldable edge;
(c) a foldable/non-foldable intersection is located between the non-foldable edge and the foldable edge;
(d) a front side/top side edge is located at the interface of the front side and the top side, wherein the front side/top side edge comprises a non-moveable edge and an adjacent moveable edge;
(e) a movable/non-movable edge intersection is located between the non-moveable edge and the adjacent movable edge;
(f) a front-top flap defined by: a finger tab located at the front side integral to the moveable edge; a line of weakness essentially extending from the finger tab to the foldable/non-foldable intersection through the movable/non-movable edge intersection; and wherein the front-top flap is capable of unfolding open along the folding edge; and
(g) wherein at least a portion of the line weakness on the top side is a ½ cut line of weakness.
Another aspect of the invention provides the aforementioned oral care article further containing a tube of toothpaste.

½ Cut Line of Weakness
A line of weakness may include any suitable type including, for example, perforation lines, die cut lines, or score, to facilitate the opening (i.e., at least partial removal) of the front-top flap (51). In the present invention, referencing
A “½ cut line of weakness” means a line of weakness formed when a first die having a first blade cuts into the carton precursor (e.g., paperboard) about halfway through its thickness and an opposing second die having a second blade also cuts into the carton precursor about halfway through the thickness. The cuts made by the respective blades are made in a direction transverse relative to the thickness of the carton precursor. The cuts (for the first and second blades) are not made directly opposing each other, but rather, in a distance from each other from 2 mm to 10 mm, preferably from 3 mm to 8 mm, more preferably from 4 mm to 7 mm. Accordingly, each cut line (from the first and second blade) will generally mimic the other (but at the indicated distances). The user, upon unfolding open the front-top flap (51), is delaminating the carton precursor between the two cut lines. In one example, the carton precursor is a paperboard having a basis weight of 350 grams per square meter. The paperboard is made from 100% virgin paper. Preferably the paperboard is printed with the desired branding and graphics etc., (on both sides) before being subjected to the aforementioned die cutting.
A method of opening an oral care article (1) is provided. The method comprising the step of (the user) grasping the finger tab (53) and opening the front-top flap (51) by separating the front-top flap along the line of weakness (55A, 55B, 55C, 55D).

Dimensions
One advantage of the present invention is providing carton (3) with enough of an opening (upon the front-top flap (51) unfolded upon) so that the user is able to remove contents without any edges of the opening significantly impeding the removal of the contents. According, preferably the front-top flap (51) is capable of exposing from 17% to 40% of the total surface area of the six sided rectangular carton (3) upon the front-top flap (51) unfolding open (relative to the unopened carton).
Another advantage is providing the impression of a high quality carton (3) to the user by not visually exposing any portion of the flaps (constituting a portion of the panels that form the left and right sides (83, 81)) through the opening created by the unfolded open front-top flap (51). Accordingly, referencing
In another example, still referencing the carton (3) of
Having the proper dimensional relationship between the opening of the carton (3) and the tube of dentifrice is important in providing one or more of the advantages described herein. Accordingly, referencing
The dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as “40 mm” is intended to mean “about 40 mm.”
While particular embodiments of the present invention have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
