Description

A Carton Holder DESCRIPTION
[Para 1 ] This invention relates to the field of hand manipulated handling devices and more specifically a handling device adapted for cartons particularly for containing beverages.
Discussion of the Prior Art [Para 2] There are many infirmities related to aging, injury and disease which result in a reduction of motor skills and limb strength particularly in the arms and hands. For example, arthritis, carpet tunnel syndrome, muscular dystrophy and injury induced paralysis often restrict the ability of individuals to grasp and firmly hold objects such as smooth surfaced cartons containing milk. Furthermore, the height, considerable width and weight of containers, such as 1, 1.5 and 2 liter-sized cartons, make it difficult for weakened individuals to manipulate such cartons safely.
[Para 3] The prior art discloses a number of devices that are designed to aid individuals to grasp, lift and carry bottles, beverage cans and like containers. Examples include USP
5806904 issued to Smith on September 1 5, 1998; USP 5695232 issued to Tipp on December 9, 1997; USP 5183169 issued to Grzych on February 2, 1993; and, USP

issued to McCumb on April 30, 2002. However, all of these devices are not well adapted for use by persons who have diminished strength and motor skills due to age, injury or disease.
Page 1 of 21 Furthermore, these devices do not facilitate the safe manipulation of large square cartons by such persons.
[Para 4] Therefore, there continues to be a need for a carton holder that is able to conveniently hold and permit carriage and manipulation of a large carton by an individual with reduced or weakened hand strength.
OBJECTS OF THE INVENTION
[Para 5] It is a principle object of the present invention to provide a carton holder that overcomes the deficiencies noted above.
[Para 6] Another object of this invention is to provide a carton holder that is specifically designed for individuals that have reduced hand strength due to age, injury or disease.
[Para 7] It is a further object of the invention to provide a carton holder that is comfortable and safe to use by persons with weakened hand strength.
[Para 8] It is yet another object of the invention to provide a carton holder that is lightweight, easy to manufacture and inexpensive to purchase.
SUMMARY OF THE INVENTION
Page 2 of 21 [Para 9] The invented carton holder is designed for use with a beverage carton having a substantially square bottom.
[Para 10] The carton holder comprises a square base adapted to accept and firmly seat the bottom of the carton. The base comprises a sleeve having an annulus, a height, an inside wall, an outside wall, a flat top surface and a flat bottom surface.
The holder also comprises two arms for firmly grasping the carton within the carton holder and a handle.
[Para 11 ] The sleeve inside wall is vertical and the sleeve outside wall has an acclivity away from the vertical.
[Para 12] In order to facilitate a controlled pouring operation by a person with weakened hand strength, there is a first pivot point located at the junction of the front of the flat bottom surface of the sleeve and the front bottom end of the sleeve outside wall and a second pivot point is located at the front top of the sleeve outside wall. The first pivot point is adapted to pivot, on a flat stable surface such as a table top, the carton holder Y-axis from a first vertical position to a second position wherein the carton holder Y-axis is at an angle of no more than 45 degrees from the vertical. The second position is an intermediate stable position whereby the carton is resting on the flat front of the outside wall of the sleeve. The second pivot point is adapted to pivot the carton holder Y-axis from the second position to a pouring position.
Page 3 of 21 [Para 13] The grasping arms are formed from an open square having a front facing gap, a back end fixed to the handle top end and an inside width. The arms have an inherent resiliency so that when the carton is placed within the square the arms will have an inherent tendency to flex outwardly to accommodate the slightly larger width of the carton and subsequently exert a compressive force against the outside surface of the carton thereby firmly grasping it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[Para 23] Referring to Figure 1, there is a perspective front view of one embodiment of the invention (10), being a carton holder shown in combination with a typical beverage carton such as a milk carton (2). For orientation purposes, there is shown an X axis (15) and a Y axis (17). The carton and carton holder have a front (21 ) and a back (23).
[Para 24] The carton may have any volume but generally the size of carton contemplated by this invention is between 1 and 2 liters. The invented carton holder may be sized to Page 5 of 21 accommodate such cartons. The carton holder can be dimensioned for any sized carton of the type contemplated herein. Typically, a carton (2) is adapted to contain non-pressured beverages such as milk or juice. The carton (2) typically has a top portion (3), a spout (5), and a body portion (6) with sidewall (7) and a carton seating surface (8) comprised of four carton supporting surfaces.
(Para 25) Referring now to Figures 1 and 2, the carton holder (10) is shown in side view combination the carton (2). The carton holder is adapted to securely grasp and hold a carton in order to meet the objectives of the invention. The preferred embodiment of the carton holder shown in Figure 2 comprises base means (12) adapted to securely seat the bottom of the carton therein, carton grasping means (14) adapted to firmly grasp the carton body portion and hold it within the invention and handle means (16) disposed between and connecting together the carton grasping means (14) and base (12). The handle means allows the user to use the carton holder in a slide-grip and pistol-grip fashion as explained below.
[Para 26] Referring to Figure 1 and Figure 2, base means comprises a square sleeve (18) having an annulus (31 ), an inside surface (20) comprising four vertical walls, an outside surface (22) comprising four inclined walls, a top surface (24) and a bottom surface (26).
The sleeve has a height (25). Top surface (24) is flat. Bottom surface (26) is also flat and provides overall stability on the X-axis (15) and about the Y axis (17) of the invention when holding a carton as depicted in Figure 1. Annulus (31 ) has a generally square shape having a generally equal length (28) and width (30). Sleeve inside surface (20) is vertical and adapted to engage in a contacting relationship the outside surface of the carton resulting in carriage of the weight of the upright carton by the sleeve bottom surface.
Page 6 of 21 [Para 27] Referring now to Figure 1 and Figure 3, there is shown the invented carton holder in combination with a carton. The hand (33) is inserted between the handle (16) and the carton (2) in a slide-grip fashion. The slide-grip is used when the individual does not have the hand strength or motor skills necessary to firmly grasp the handle in a pistol-grip fashion. The weight of the carton holder and carton combination is balanced on the dorsal side of the hand as illustrated in Figure 3 and the force required to move the carton holder and carton combination from a vertical position to a pouring position and back to a vertical position can be provided by the arm and shoulder. In Figure 3, the front inclined outside wall (39) of the sleeve (18) is linear and flat against table surface (41 ).
It has a slope angle (55) that facilitates tipping the carton holder and carton combination forwards along the X
axis (15) in order to pour the contents of the carton into a receptacle. First pivot point (60) is located at the bottom of the front outside wall (39) and second pivot point (62) is located at the top of the front outside wall (39). An angle (55) of less than 45 degrees from the vertical or greater than 45 degrees from the horizontal is appropriate as it permits tipping of the combination in a controlled fashion about the first pivot point (60) but prevents tipping of the combination about the second pivot point (62) unless additional force is exerted on the combination by the individual. The second pivot point (62) is adapted to pivot the carton holder and carton combination from the stable intermediate position to a third pouring orientation that is greater than 45 degrees and less than 90 degrees from the horizontal.
[Para 28] Referring now to Figure 4, the combined carton holder and carton is shown when the carton holder is gripped in a pistol-grip fashion. Front outside wall (39) is flat against the surface (41 ). The combined carton (2) and carton holder (10) are shown having passed the first pivot point (60) but not the second pivot point (62). Spout (5) is open to Page 7 of 21 pour the contents of the carton. In the pistol-grip the thumb (130) of the hand (33) is placed on the notch (71 ) adapted to receive it. The fingers of the hand (122), (124), (126) and (128) are wrapped around handle (16). Additional forward motion from the arm and shoulder of the user is sufficient to move the carton and holder about pivot point (62) to affect a pour.
[Para 29] Referring now to Figures 1 to Figure 8, carton grasping means (14) is adapted to firmly grasp the carton and hold it within carton holder. Grasping means (14) comprises an open square (70) having an open front end thereby forming gap (80). The open square is defined by a first arm (72) and a second opposing arm (74). The back portion (76) of the square (70) is fixed to the top end of the handle (16) and integral therewith.
The tips (81 ) and (83) respectively of arms (72) and (74) are in a confronting relationship with gap (80) between them. The inside width and length of the square are slightly smaller than the length and width of the carton it is intended to hold so that when a carton is placed within the square the arms will have an inherent tendency to flex outwardly to accommodate the slightly larger dimensions of the carton. Once the carton is inserted within square (70) the arms will exert a compressive force against the outside surface of the carton thereby firmly grasping it in a squeezing relationship.
[Para 30] Still referring to Figures 1 to 8 handle means (16) is described.
Handle means (16) is an inclined member having a top end (1 O1 ) and a bottom end (103). It has been ergonomically designed to permit manipulation of the combined carton and carton holder by a person with weakened hand strength caused by disease, accident or aging in a slide-grip as shown in Figure 3 or in a pistol-grip fashion as shown in Figure 4.
Handle means (16) joins the base means (12) and grasping means (14). The length of handle means (100) Page 8 of 21 is sufficient to permit the hand to grasp handle means as shown in Figure 4 in a pistol-grip fashion and to permit the carton grasping means (14) to contact the carton held within the carton holder at a point near centre of gravity of a full carton for stability. The top end (1 O1 ) of handle means (16) includes a notch (71 ) adapted to accommodate the curved profile of a human thumb pad which facilitates grasping and manipulation of the carton holder. The bottom end (103) of handle means includes a chin-shaped projection (106) that is about one inch in length along the X-axis. The bottom surface of the projection is flat and contiguous with the bottom surface (26) of sleeve (18). The purpose of the projection is to ensure stability about the X axis of the carton and carton holder combination by preventing a pivoting action about the bottom (103) of the handle when the carton is returned to an upright position. For example, as described previously, and referring to Figures 3 and 4, when the carton is returned from a pouring position to a vertical position, the individual with weak hand strength may not be able to adequately control the carton as it pivots about first pivot point (60) back to the vertical position.
Therefore, the projection (106) exists to ensure that the combination carton and carton holder does not rotate backwards about the bottom of handle means.
[Para 31 ] Handle means (16) inside surface (110) includes a gripping surface (1 12) that includes a plurality of aligned alternating raised areas (1 14) and hollows (116) of diminishing size from top to bottom that are adapted to conform to the circumference of an individual's fingers when gripped in a pistol grip fashion as illustrated in Figure 4. In the pistol gripping mode the palmal sides of the index (122), middle (124), ring (126) and small (128) fingers are in comfortable contact with the hollows and the thumb pad (130) is in contact with groove (71 ). The inside surface of handle means is sufficiently wide to Page 9 of 21 comfortably distribute the weight of the carton and carton holder combination across the dorsal side of the individual's fingers.
[Para 32] As shown in Figure 3, the raised areas (1 14) and hollows (1 16) are also adapted to conform to dorsal side of an individual's fingers when the carton holder and carton combination is being manipulated in a slide-grip fashion. In this gripping mode the dorsal side of the base of the metacarpals (132), (134), (136) and (138) of each finger is in contact with the hollows with the carpals (knuckles) (not shown) acting as an abutment against the grip. The thumb pad (130) is positioned at (140) on top of the handle at the point where square (70) joins handle means (16). To reduce stress in the thenar muscles between the thumb and the index finger (122) that control the thumb (129), square (70) is joined to the handle at a point slightly below the top (1 Ol ) of handle means. This is illustrated in Figure 3, where the top crest (1 O1 ) of handle means is shown rising slightly above the back of square (70). Being able to use a slide grip permits the lifting and manipulation of a carton and carton holder combination as the weight of the carton is carried on the dorsal side of the hand and no grasping is required to control the carton.
[Para 33J Handle means (16) possesses an acclivity (150) that creates a void (1 52) between the inside surface (110) of handle means (16) and the outside surface of the carton (2) to permit the fingers of a person's hand to grasp handle means in either a pistol- grip or slide-grip fashion. The acclivity (150) is generally less than 30 degrees from the vertical but may be more or less in other possible embodiments of the invention.
Page 10 of 21 [Para 34] The carton holder is manufactured by means of known injection molding techniques using known light weight and resilient materials that are capable of maintaining their resiliency when under cold temperatures. Injection molding permits easy and inexpensive manufacturing of the invention.
[Para 35] The invented carton holder and carton and carton holder combination are applicable in any situation where the gripability and ability to manipulate of a large carton needs to be augmented. It is advantageously applicable in situations where persons who have weakened hand strength and motor skills need to manipulate large cartons.
[Para 36] Although this description contains much specificity, these should not be construed as limiting the scope of the invention by merely providing illustrations of some of the embodiment of the invention. Thus the scope of the invention should be determined by the appended claims and their legal equivalents rather than by the examples given.
