SURGICAL GLOVE CARTON BACKGROUND OF THE INVENTION 1. Field of the Invention:

This invention relates to a carton for packaging a single pair of sterilized surgical gloves.

2. Description of the Prior Art:

A preliminary patentability search revealed the following U. S. Patents: Yerk U.S. Pat. No. 2,810,417; Dearholt U.S. Pat. No. 2,908,308; Langdon U.S. Pat. No. 2,915,173; Stanley U.S. Pat. No. 3,024,900; Langdon US Pat. No. 3,187,987; Quade et al. U.S. Pat. No. 3,369,657; and Taterka U.S. Pat. No. 3,409,121. None of the above references show or suggest applicants device. However, it should be noted that at least two of the above references pertain to a surgical glove carton which is designed to be completely unfolded to expose the gloves in their entirety by pulling a pair of flaps or tabs provided for this purpose, i. e., the 657 patent and the 121 patent. In this regard, it will be appreciated that both the 657 package and the '121 package must be partially opened manually prior to gaining access to certain manipulation tabs or flaps thereof. Further, neither of these latter two patents include means for securing or locking the package per se. However, it should be mentioned that the usual practice is to insert the package inside a pouch or bag as depicted in FIG. 3 of the 121 patent.

SUMMARY OF THE INVENTION The present invention is directed toward overcoming certain disadvantages and/or problems relative to previous surgical glove cartons. The concept of the present invention is to provide a flat sheet of flexible cardboard or other relatively stiff sheet material which may be suitably shaped and provided with certain fold lines to be later folded thereon to constitute a carton for enclosing a pair of surgical gloves. The gloves and the carton are processed through the usual sterilizing apparatus, e. g., infrared light or the like. Accordingly, the gloves remain sterile in the carton for an indefinite period, e. g., until the gloves are intended to be placed into service at which time the carton is opened.

The carton is provided with structure which causes it to snap open to a flat disposition which exposes or presents the gloves to the user on a sterile field of cardboard which makes them convenient to don and completely free of contamination. An important concept of the present invention is the locking feature which provides means for positively keeping the carton per se in a flat disposition until such time as the user intends to don the gloves. Equally important is the simplicity in opening a carton, i. e., the user simply grasps certain exposed portions of the enclosed carton and pulls these portions in opposite directions, thus causing the carton to snap open. It should be understood that the term user" as herein disclosed may or may not be one individual person. For example, the person that opens the carton may be unsterile and assisting the sterile person that will don the gloves. In other words, the outside of the carton will be assumed to be contaminated and should not be touched by the person donning the gloves.

DESCRIPTION OF THE PREFERRED EMBODIMENT The carton 11 of the present invention, as best viewed in FIG. 7 of the drawings, is intended for packaging a pair of

surgical gloves

13, 15 as best viewed in FIGS. 1 3 of the drawings. The carton 11 is preferably formed from a flat sheet of cardboard or a blank 17 having a shape substantially as depicted in FIG. 1 of the drawings.

The carton 11 generally comprises a pair of large

main body panels

19, 21 for restingly supporting the pair of

gloves

13, 15. The

main body panels

19, 21 respectively have a greater width and length thereto than do the pair of

gloves

13, 15 and are joined together by a first vertically extending fold line 23. The panel 19 includes a distal edge 25 and the panel 21 includes a distal edge 27, i. e., the

distal edges

25, 27 being spaced a distance outwardly from the vertical fold line 23. The

carton 1 1 also includes a plurality of smaller panels and a plurality of certain other fold lines which will be fully disclosed later in the specification. Additionally, tab means 29 is included for reasons yet to be disclosed. Also included is a lock means 31 adjacent the distal edge 25 of the panel 19. The lock means 31 includes structure for coacting with the distal edge 27 of the panel 21 for locking the folded carton 11 in a closed disposition with a portion of the tab means 29 being exposed as clearly shown in FIG. 7 of the drawings and which will be more fully disclosed later in the specification. FIGS. 7 and 8 of the drawings depict a manner whereby grasping the tab means 29 and the distal edge 25 of the panel 19 is effective to disengage the lock means 31 and to cause the carton 11 to snap open to a flat disposition substantially as depicted in FIG. I of the drawings, i. e., the carton 11 ,opens in three directions outwardly from the

main body panels

19, 21.

A detailed disclosure of the blank 17 as depicted in FIG. 1 of the drawings is as follows: The previously described first vertical fold line 23 extends between the previously described left and right

main body panels

19, 21. Accordingly, a pair of

upper flap panels

33, 35 are included and respectively are joined to the left and right

main body panels

19, 21 by an upper horizontally extending fold line 37. A pair of lower

flat panels

39, 41 are included which respectively are joined to the left and right

main body panels

19, 21 by a lower horizontal fold line 43. The

upper flap panels

33, 35 are separated by an upwardly directed fold line segment 45 constituting an extension of the first vertically extending fold line 23. The

lower flap panels

39, 41 are separated by a downwardly directed fold line segment 47, also constituting an extension of the fold line 23.

The blank 17 also includes second and third vertically extending

fold lines

49, 51 which are positioned adjacent the distal edge 25 of the left main body panel 19. An outer margin portion 53 of the panel 19 projects from the second vertical fold line 49, i. e., the fold line 49 defining in part the outer margin portion 53. The outer margin portion 53 has a dimensional width thereto which is greater than the spaced apart distance between the

vertical fold lines

49, 51 for reasons yet to be disclosed.

A right flap panel 55 is included and is joined to the distal edge 27 of the right panel 21 by a fourth vertically extending fold line 57. The tab means 29 includes a root portion 59 and a tip portion 61 with the root portion 59 being joined to the right flap panel 55 by a fifth vertically extending fold line 63 and the tip portion 61 being joined to the root portion 59 by a sixth vertically extending fold line 65.

An upper comer panel 67 is included which is joined to the right upper flap panel 35 by a fold line segment 69 constituting an upwardly directed extension of the fourth vertical fold line 57 and being joined to the right flap panel 55 by a fold line segment 71 constituting an outwardly directed extension of the upper horizontal fold line 37.

A lower comer panel 73 is included and is joined to the right lower flap panel 41 by a fold line segment 75 constituting a downwardly directed extension of the fourth vertical fold line 57 and is joined to the right flap panel 55 by a fold line segment 77 constituting an outwardly directed extension of the lower horizontal fold line 43.

It will be appreciated by"those skilled in the art that the fold line 37 tapers downwardly or toward the fold line 43 from the

distal edges

25, 27 toward the vertical fold line 23. Additionally, the line segment extension 71 tapers downwardly toward the tab means 29 from the vertical fold line 57. Further, the lower horizontal fold line 43 tapers upwardly toward the horizontal fold line 37 from the

distal edges

25, 27 toward the vertical fold line 23. Additionally, the fold line segment 77 tapers upwardly toward the tab means 29 from the vertical fold line 57. In other words, the above described non-straight courses for the various scorelines is to prevent folds from overlaying directly one on the other, a common expedient well known to those skilled in the art.

The upper corner panel 67 is provided with an upper diagonal fold line 79 commencing substantially at the convergency of the fourth vertical fold line 57 and the upper horizontal fold line 37 and extends upwardly and outwardly therefrom. The lower corner panel 73 includes a lower diagonal fold line 8] commencing substantially at the convergency of the fourth vertical fold line 57 and the lower horizontal fold line 43 and extends downardly and outwardly therefrom.

The blank 17 is provided with upper and

lower notches

83, 85 with the upper notch 83 being positioned along the uppermost edge of the blank 17 and extending downwardly a predetermined distance so as to partially separate the upper flap panel 35 and the upper corner panel 67. The lower notch 85 is positioned along the lowermost edge of the blank 17 and extends upwardly a predetermined distance so as to partially separate the flap panel 41 from the lower corner panel 73, i. e., the

notches

83, 85 being substantially as depicted in FIG. 1 of the drawings.

The carton 11 includes adhesive means 87 which is applied to the blank 17 so as to substantially overlay the entire area of the main body panel 19 between the second and third

vertical fold lines

49, 51. The main body panel 19 is doubled or folded over inwardly along the second vertical fold line 49 so that a portion of the outer margin portion 53 is fixedly joined to the adhesive means 87. The outer margin portion 53 was described earlier in the specification as having a width greater than the distance between the second and third

vertical fold lines

49, 51. Accordingly, fixedly joining the portion thereof adjacent the second fold line 49 establishes a free portion 89 as clearly shown in FIGS. 6 and 8 of the drawings which may extend inwardly a predetermined distance between the first and third

vertical fold lines

23, 51 or between the adhesive means 87 and the fold line 23 to establish in part the previously men tioned lock means 31.

It will be appreciated by those skilled in the art that the blank 17 may optionally have one step in the folding sequence accomplished prior to the shipping thereof to the glove manufacturer. In other words, the above-described adhesive means 87 preferably is applied as above-described and the outer margin portion 53 preferably is folded along the second vertical fold line 49 so that when the blank 17 is received by the glove manufacturer, it is ready to have the

gloves

13, 15 packed therein.

Therefore, the following disclosure pertains to the folding sequence of a pre-glued blank 17 which is not separately shown in the drawings. The first step in the packaging sequence comprises laying the gloves 13, 1S flat on the respective left and right

main body panels

19, 21 as clearly depicted in FIGS. 1 and 2 of the drawings. The second step includes folding the blank 17 inwardly along the vertical fold line 57 and the extensions 69, thereof. The third step includes folding the tab means 29 outwardly along the vertical fold line 63, thus the blank 17 assumes a disposition substantially as depicted in FIG. 2 of the drawings.

The fourth step includes the transition depicted between FIGS. 2 and 3 of the drawings, i. e., folding the upper pair of

flat panels

33, 35 inwardly and downwardly along the horizontal fold line 37 and the extension 71 thereof and folding the lower pair of

flap panels

39, 41 inwardly and upwardly along the lower horizontal fold line 43 and the extension 77 thereof.

The fifth step in the packaging or folding sequence includes the transition depicted between FIGS. 3 and 4 of the drawings, i. e., folding the blank 17 inwardly along the vertical fold line 23 and along the

extensions

45, 47 thereof. From FIGS. 3 and 4 of the drawings, it may be seen that the main body panel 19 establishes a bottom for the carton 11 and the main body panel 21 substantially establishes a top for the carton 11. In other words, the

panels

33, 35, 39, 41, 55, 59, 61, 67,

73 and the

gloves

13, 15 are sandwiched between the bottom of the carton 11 or the main body panel 19 and the top of the carton 11 or the main body panel 21. Further, the distal edge 27 and the tip portion 61 of the tab means 29 is in a disposition overlaying the free portion 89 of the outer margin 53 of the panel 19, i. e., a condition preparatory to engaging the lock means 31 in a manner yet to be described.

From FIG. 6 of the drawings, it may be seen that the lock means 31 includes the free portion 89 of the outer margin 53 coacting with the distal edge 27 of the panel 21. The lock means 31 is engaged by folding the outer margin portion 53 downwardly as shown in FIG. 6 along the vertical fold line 51 which causes the tip portion 61 of the tab means 29 to bend upwardly along the vertical fold line 65. Releasing the distal edge 25 or the outer margin portion 53 allows the resiliency of the relatively stiff sheet material to urge the distal edge 25 upwardly to a position in line with main body panel 19.

Accordingly, the free portion 89 assumes a disposition overlaying the distal edge 27 of the panel 21 and a portion of the tip 61 is exposed as clearly shown in FIGS. 7,8 of the drawings. In the event it is desirable to seal the carton 11, it may be enclosed in a typical sealable package, e. g., like that depicted in FIG. 3 of the aforementioned '121 patent.

Opening the carton 11 is accomplished by simply grasping the distal edge 25 with the fingers FL of the left hand and the tip 61 of the tab means 29 with the fingers FR of the right hand, substantially as depicted in FIGS. 7 and 8 of the drawings. The distal edge 25 is urged in the direction of the arrow 91 and the tip 61 of the tab means 29 is urged in the direction of the arrow 93 which is effective to disengage the lock means 31 and cause the carton 11 to snap open in three directions to a flat disposition presenting the

gloves

13, 15 on a sterile field encompassing the entirety of the blank 17 substantially as depicted in FIG. 1 of the drawings.

At least two types of fold lines are well known to those skilled in the art: The scored fold line and the perforated fold line. Accordingly, I prefer that the fold lines 23, 49, 51, 79, 81 be of the scored fold line type. Further, the fold lines 37, 43, 45, 47, 57, 63, 65, 69, 71, 75, 77 preferably are the perforated type. Accordingly, the carton 11 will assume a relatively flat disposition as depicted in FIGS. 5, 6, 8 when folded in the above disclosed sequence.

Although the invention has been described and illustrated with respect to a preferred embodiment thereof, It is not to be so limited since changes and modifications may be made therein which are within the full intended scope of the invention.
