BACKGROUND OF THE INVENTION
A considerable part of the expense of supplying sterile gloves to the medical field is the cost of packaging the glove. The present invention relates to a glove formed on a support web to which is applied a protective cover sheet thus defining a sealed pouch containing the glove. Such gloves are employed for medical examination purposes and inevitably become contaminated in use. It is desirable to have a disposal method which avoids contamination and which also provides a convenient means for disposing of frequently esthetically offensive gloves.
Accordingly, it is a principal object of this invention to provide a plastic glove removably supported on a flexible substrate enclosed by a flexible plastic film sheath sealed to the substrate along a line surrounding the glove.
A further object is to provide a plastic film glove-package which provides a pouch for receiving the glove after initial removal therefrom.
These and other objects, features and advantages of the invention will, in part, be pointed out with particularity and will, in part, become obvious from the following more detailed description of the invention, taken in conjunction with the accompanying drawing, which forms an integral part thereof.
DESCRIPTION OF THE DRAWING
In the various figures of the drawing like reference characters designate like parts.
In the drawing:
FIG. 1 is a plan view of a glove in its integral pouch;
FIG. 2 is a view similar to FIG. 1 but partially broken away;
FIG. 3 is a sectional view taken along line 3--3 of FIG. 1;
FIG. 4 is a perspective view of the pouch employed as a receptacle; and
FIG. 5 is a schemation view showing of an apparatus for making the integral glove pouch.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to FIG. 1, there is shown a pouch 10 containing a glove 12 sealed therein. In FIGS. 2 and 3 there is shown the various layers of material comprising the article. A support web 14 which may be a paper sheet has impressed thereon two layers of plastic film 16, 17 sealed along an outline 18 defining a glove. There is a plastic film cover sheet 20 heat sealed along line 22. The corners 24, 25 are left unsealed as pull tabs so that the package may be opened. Bar welds 26, 27 serve to direct the tearing off of a strip of the plastic cover sheet to open the pouch.
Once the pouch is open the hand is readily inserted into the glove since the glove is supported upon the substrate.
It is contemplated that after the package is completed it be gas sterilized. For long term protection the substrate may be polyethylene coated or otherwise sealed on the face away from the glove. The side of the substrate supporting the glove should be left uncoated so that the glove be readily removable from the substrate.
The empty pouch 10' may be used to receive used gloves 12' as shown in FIG. 4.
Suitable materials include paper for the substrate and preferably opaque polyethylene or polythylene copolymer film having a thickness of about 0.0005 inch to 0.007 inch thick.
In FIG. 5 there is shown an apparatus for carrying the invention. This apparatus is disclosed and claimed in the copending application of William Baab, Ser. No. 346,740, filed Apr. 2, 1973, and assigned to the common assignee of this application.
Turning now specifically to FIG. 5, there is shown the apparatus that is used forming the improved article of manufacture of the present invention. A first web 14 of a flexible moisture absorbent material, such as paper that is adapted to form a support layer, is passed over a tension roller 32 which is suitably journaled for rotation. The web of paper 14 then passes over and almost completely around a lay-on roller 34 that is rotatably mounted on a pivotally supported arm 36. The roller 34 applies the paper to the peripheral surface of a carrier such as a drum 38 that is adapted to rotate about an axle 40. Suitable means such as a motor (not shown) may be used for driving the drum 38.
Concurrently with the feeding of the paper web 14, a pair of heat sealable, thermoplastic film layers 16 and 17, typically between 0.0005 and 0.007 inch thick, are passed through a plurality of tension rollers 46a, 46b and 46c that transport the two layers 16 and 17 to an adjustable lay-on roller 48 which is pivotally mounted on an arm 50. Spring means 52 bias the roller 48 in the direction towards the peripheral surface of the drum 38 so that both film layers 16 and 17 are pressed downwardly on the surface of the paper web 14.
While the drum 38 rotates the paper layer 14 and the film layers 16 and 17 are carried by the peripheral surface thereof past a die member 54 that is provided with selected heated portions in the shape of the desired article. In the embodiment described herein the heated portions of the die member 54 will have the shape of the glove 12 shown in FIG. 1. When the film layers 16 and 17 are passed between the peripheral surfaces of the rotating die member 54 and the drum 38, the heat from the die member will heat seal the two layers 16 and 17 only along the lines designated 18 in FIG. 2 to thereby form the gloves. A roller 56 that is adapted to apply a suitable mold release agent such as silicone may be provided in contact with the peripheral surface of the heated die member 54.
Immediately downstream of the heated die member 54, in the direction of rotation of the drum member 38, there is provided a film and paper support roller 58 that serves to retain the formed gloves 12 on the surface of the paper web 14. The remainder of the material of the film layers 16 and 17, which does not form the glove 18, is removed by a scrap removal system generally designated by the reference character 60 which is adapted to apply suction to the non-formed plastic layers.
Still another layer of heat sealable thermoplastic material 20, typically between 0.0005 and 0.007 inch thick, is applied to the moving drum 38 subsequent to the formation of the glove 16, as described hereinabove. It is convenient to provide the web 20 from a source 64. The web 20 passes over a tension roller 68 and then an adjustable film lay-on roller 70 that is pivotally supported on an arm 72. Thus, as shown in FIG. 3, the web 20 is positioned over the formed glove 16. Immediately downstream of the film lay-on roller 70 there is provided another die member 74 having a heated portion that is adapted to form the continuous seal lines 22 shown in FIG. 1. If desired, a roller 76 that is adapted to carry a supply of a mold release agent such as silicone may be placed in contact with the peripheral surface of the second heated die member 74. A support roller 78 immediately downstream of the die member 74 maintains the layers of plastic film 16, 17 and 20 against the paper web 14.
A sensor 80, a pair of draw rollers 82 and 84 and cut-off means 86 and 88 are provided downstream of the support roller 78 in order to separate each of the articles 10 from the remainder of their respective webs. Conventional stacking means (not shown) may also be provided for collecting the cut-off articles 10.
There has been disclosed heretofore the best embodiment of the invention presently contemplated. However, it is to be understood that various changes and modifications may be made thereto without departing from the spirit of the invention.
