DETAILED DESCRIPTION OF THE INVENTION

[0018] Referring to FIGS. 1 and 2, a perspective view and an assembly view of one possible embodiment of a shaving razor cartridge package 10 are illustrated, respectively. The shaving razor cartridge package 10 may include a shaving razor cartridge dispenser 12 with an optional lid 14. The shaving razor cartridge dispenser 12 may include a formed container 16 defining an enclosed region 18 having a rim 20 around an entrance to the enclosed storage region 18. The rim 20 may have many different configurations. For example, the rim 20 may include a flange, stepped surface, a rounded edge or a straight edge. The lid 14 may be sealed to the formed container 16 with a pressure sensitive adhesive or other conventional methods known to those skilled in the art. The shaving razor cartridge dispenser 14 may be interconnected to additional shaving razor cartridge dispensers 14 or manufactured as single unit.

[0019] The lid 14 and/or the formed container 16 may comprise one or more cellulose-based products such as cardboard, paperboard, paper sheet, bamboo and other sustainable, compostable, biodegradable or recycled/recyclable materials. The lid 14 and/or the formed container 16 may also be made from a slurry of water and pulp from fibrous materials, such as virgin pulp or recycled paper products, or other natural fibers (e.g., sugarcane, bamboo, wheat straw). The raw materials may help determine the color, surface texture and strength of the lid 14 and/or the formed container 16. The pulp may be formed into a shape by custom designed molds. The molds may be lowered into a pulp mixture and water pulled through a mesh of the mold with a vacuum. An upper part of the mold may press into the lower part of the mold to arrive at the final shape. The shaving razor cartridge dispenser 12 may be formed with numerous other processes, such as drawing, folding, stamping, molding, thermoforming, 3D printing, dry forming and wet forming. In certain embodiments, the lid 14 may comprise a different material than the formed container 16. For example, the lid 14 may include a polymer film that is sealed to the shaving razor cartridge dispenser 12, which can be peeled off to gain access to the enclosed region 18. In other embodiments, the lid 14 may be connected to the formed container 16 with a thin web of material to form a hinge.

[0020] In certain embodiments, the shaving razor cartridge dispenser 12 may include one or more branding logos and/or indicia 22 on an upper surface 24 of the formed container 16. The one or more branding logos and/or indicia 22 may be embedded in the upper surface 24 from a forming or molding process. Alternatively, the one or more branding logos and/or indicia 22 may be printed on the upper surface 24 either directly or with a label. The upper surface 24 may extend from the rim 20 toward the enclosed storage region 18.

[0021] The shaving razor cartridge dispenser 12 may include a shaving razor cartridge 26. A single shaving razor cartridge 26 may be positioned within the enclosed storage region 18 of the formed container 16. The shaving razor cartridge 26 may have an overall width of d1. The distance d1 may be representative of commercially available shaving razor cartridges, for example, d1 may be about 37 mm to about 52 mm. As will be explained in greater detail below, the shaving razor cartridge 26 may be retained within the enclosed storage region 18 by an interference fit created by the formed container 16. The shaving razor cartridge 26 may be retained so it does not become dislodged or fall out of the formed container 16 during handling and handling.

[0022] Referring to FIGS. 3A and 3B, a first and second side perspective view of the shaving razor cartridge dispenser 12 FIG. 1 is illustrated with the lid 14 removed for clarity. The shaving razor cartridge 26 of FIG. 1 has also been removed for clarity to better illustrate the formed container 16. The formed container 16 may have an inner bottom wall 28. In certain embodiments, the inner bottom wall 28 may include a pair of spaced apart support walls 30 and 32. The shaving razor cartridge 26 of FIG. 1 may rest on the pair of support walls 30 and 32 such that the shaving razor cartridge 26 of FIG. 1 is spaced apart from a portion 34 of the inner bottom wall 28 that extends between the pair of support walls 30 and 32. The spacing of the shaving razor cartridge 26 from the portion 34 of the inner bottom wall 28 may facilitate the drying of the shaving razor cartridge 26 after use. The spacing of the shaving razor cartridge 26 from the portion 34 of the inner bottom wall 28 may also help prevent a lubrication member of the shaving razor cartridge from bonding to the inner bottom wall 28. In certain embodiments, the portion 34 may be flat. However, it is understood, the portion 34 may include various textures.

[0023] The formed container 16 may include two opposed side walls 36 and 38. Each of the two side walls 36 and 38 may be connected by a front wall 40 and a rear wall 42. The two opposed side walls 36 and 38 may each have a respective inner convex surface 44 and 46 positioned between the rim 20 and the inner bottom wall 28, which may include the support walls 30 and 32. In certain embodiments, the inner convex surfaces 44 and 46 may have a respective height h1 and h2 of about 1 mm to about 10 mm and more preferably about 3 mm to about 6 mm. The heights h1 and h2 may vary depending on the size of a shaving razor cartridge to be held within the storage region 18. In certain embodiments, the inner convex surfaces 44 and 46 may extend the full height from the rim 20 to the inner bottom wall 28 to maximize retention of the shaving razor cartridge 26, thus providing a larger area to retain the shaving razor cartridge 26 of FIG. 1.

[0024] The inner convex surfaces 44 and 46 may serve to retain the shaving razor cartridge 26 of FIG. 1. Typical shaving razor cartridge dispensers utilize lugs or undercuts (e.g., snap fits); however these types of designs are not practical for manufacturing processes of sustainable materials (e.g., forming). Sustainable materials do not have similar properties to plastics which allow for the formation of various features by injection molding or thermoforming. The inner convex surfaces 44 and 46 may each have a radius of about 5 mm to about 35 mm and preferably about 10 mm to about 30 mm. If the radii are too small there may not be sufficient engagement between the convex surfaces 44 and 46 and the shaving razor cartridge 26 (FIGS. 1 and 2). In addition, if the radii are too large or even a straight or flat surface, tolerancing the proper interference between the convex surfaces 44 and 46 and the shaving razor cartridge 26 (FIGS. 1 and 2) may be difficult. For example, small dimensional changes may result in a fit that is too tight or too loose.

[0025] As will be described in greater detail below, the shaving razor cartridge 26 of FIG. 1 may be positioned within the storage region 18, such that the shaving razor cartridge 26 contacts the inner convex surfaces 44 and 46, deflecting the inner convex surfaces 44 and 46 in an outward direction. In certain embodiments, the convex surfaces 44 and 46 may undergo permanent deformation. In other embodiments, the convex surfaces 44 and 46 may temporarily deform so the convex surfaces 44 and 46 are able to retain the shaving cartridge 26 even after the shaving cartridge 26 has been inserted and removed from the formed container 16 multiple times.

[0026] As shown in FIGS. 3A, 3B and 4, the two opposed side walls 36 and 38 may each have a respective outer concave surface 48 and 50 that extend between the rim 20 and an outer bottom wall 52 (FIG. 4). Accordingly, the two opposed side walls 36 and 38 may serve a dual function by not only retaining the shaving razor cartridge 26 of FIG. 1, but also providing an intuitive gripping region for a consumer to hold the shaving razor cartridge dispenser 12 as they are inserting and removing the shaving razor cartridge 26. In certain embodiments, the outer concave surfaces 48 and 50 may correspond to the inner convex surfaces 44 and 46. For example, a radius of the outer concave surfaces 48 and 50 may match a radius of the corresponding inner convex surfaces 44 and 46. The outer concave surfaces 48 and 50 may each have a radius of about 5 mm to about 35 mm and preferably about 10 mm to about 30 mm. The outer convex surfaces 44 and 46 may be textured or have protrusions to improve grip an provide a visual indicia for the consumer to hold the shaving razor cartridge dispenser 12. The outer concave surfaces 48 and 50 may extend continuously from the rim 20 to the outer bottom wall 52. The outer concave surfaces 48 and 50 may each have a single radius. In certain embodiments, the outer concave surfaces 48 and 50 may have a respective height h3 and h4 of about 3 mm to about 20 mm and more preferably about 3 mm to about 10 mm. In certain embodiments, the outer concave surfaces 48 and 50 may extend from the rim 20 toward the outer bottom wall 52. In other embodiments, the outer concave surfaces 48 and 50 may extend the full height from the rim 20 to the outer bottom wall 52 to provide a larger area for a consumer to hold the shaving razor cartridge dispenser 12 with their digits.

[0027] A user may grip the outer concave surfaces 48 and 50 of the side walls 36 and 38 and engage one end of a handle (not shown) with the shaving razor cartridge 26 positioned within the storage region of the formed container 16. The user may then pull up on the handle to overcome the force of the inner convex surfaces 44 and 36 to remove the cartridge from the dispenser. The user can also place the shaving razor cartridge 26 back into the shaving razor cartridge dispenser 12 after use by inserting it into the enclosed region 18 to overcome the force of the inner convex surfaces 44 and 36 when pushing down, and then releasing the shaving razor cartridge 26 from the handle.

[0028] In certain embodiments, the formed container 16 may include a first flat flange surface 54 between the outer concave surface 48 and the rim 20 and a second flat flange surface 56 between the outer concave surface 50 and the rim 20. The first and second flat flange surfaces 54 and 56 may facilitate the placement of a user's digits when they are holding the shaving cartridge dispenser 12. For example, the first and second flat flange surfaces 54 and 56 may help keep a user's digits from interfering with insertion and removal of the shaving razor cartridge 26 (FIG. 2) by keeping the user's digits from extending over the rim 20 and the enclosed region 18.

[0029] Referring to FIG. 5, a top view of the shaving razor cartridge dispenser 12 is illustrated. In certain embodiments, a distance d2 between the inner convex surfaces 44 and 46 may be slightly smaller than d1 (FIG. 2). For example, the distance d2 between the inner convex surfaces 44 and 46 may be less than the distance d1 of the overall width of the shaving razor cartridge 26 (FIG. 2) by about 0.25 mm to about 5.0 mm and more preferably about 0.75 mm to about 2.0 mm total interference, to create an interference fit for holding the shaving razor cartridge 26 (FIG. 2) in place. A first pair of inner concave surfaces 58 and 60 may connect the front wall 40 to the pair of opposing side walls 36 and 38. A second pair of inner concave surfaces 62 and 64 may connect the rear wall 42 to the pair of opposing side walls 36 and 38. The first pair of inner concave surfaces 58 and 60 and the second pair of inner concave surfaces 62 and 64 may each have a radius of about 1.0 mm to about 5.0 mm and preferably about 2.0 mm to about 4.0 mm to help prevent tearing or weakening of the formed container 16 during manufacturing (e.g., dry or wet forming).

[0030] Referring to FIG. 6, a cross sectional view of the shaving razor cartridge dispenser 12, taken generally along the line 6-6 of FIG. 1. The lid 14 has been removed for clarity. The shaving razor cartridge 26 may be positioned within the enclosed region 18 of the formed container 16. The shaving razor cartridge 26 may engage the inner convex surfaces 44 and 46 of the respective side walls 36 and 38. The inner convex surfaces 44 and 46 may deflect to retain the shaving razor cartridge 26. In certain embodiments, the shaving razor cartridge 26 may permanently deform the inner convex surfaces 44 and 46, depending on the material of the formed container 16, stress levels applied and the length of time the shaving razor cartridge 26 is retained between the inner convex surfaces 44 and 46. However, it is understood that the inner convex surfaces 44 and 46 may also have an elastic deformation component to allow the shaving razor cartridge 26 to still be retained between the inner convex surfaces 44 and 46 even after several cycles of insertion and removal. The shaving razor cartridge 26 may push again the inner convex surfaces 44 and 46 such that they may no longer be convex while the shaving razor cartridge 26 is held in place. The inner convex surfaces 44 and 46 may return to a generally convex shape after the shaving razor cartridge 26 is removed.

[0031] Referring to FIG. 7, a cross section view of the shaving razor cartridge package 10, taken generally along the line 7-7 of FIG. 1. The shaving razor cartridge 26 may be positioned within the enclosed storage region 18 of the formed container 16 such the shaving razor cartridge 26 rests on the support walls 30 and 32 (FIG. 6). A bottom surface 66 of the shaving razor cartridge 26 may be spaced apart from the portion 34 of the inner bottom wall 28 that extends between the pair of support walls 30 and 32 (FIG. 6). Accordingly, there may be a gap G1 between the shaving razor cartridge 26 and the portion 34 of the inner bottom wall 28, as shown in FIG. 6. The gap G1 may be about 0.5 mm to about 5 mm to allow for improved drying of the shaving razor cartridge 26 after use. The gap G1 may also help prevent bridging which may occur between a lubrication member 68 (as shown in FIG. 7) on the shaving razor cartridge 26 and the inner bottom wall 28, which can cause the lubrication member 68 to adhere to the inner bottom wall 28.

[0032] The lid 14 may be mounted to the rim 20 of the formed container 16. In certain embodiments, the lid 14 may be pressed fitted to the formed container 16 to allow for easy removal. In other embodiments, the lid 14 may be fixed to the formed container 16 (e.g., the rim 20) with a pressure sensitive adhesive or other conventional methods known to those skilled in the art.
