No. 552,305 Claims priority, application Australia, May 27, 1965, 59,430/ 65 7 Claims. (Cl. 229-72) ABSTRACT OF THE DISCLOSURE The invention provides a pack for surgeons gloves com prising an envelope having a body adapted to receive a pair of gloves, a flap adapted to fold over said body, and an extension of the flap adapted to be folded back over said flap, whereby the pack may be handled without risk of contaminating the gloves, and may be opened without touching any portion of the flap which is likely to be contacted by the gloves when being withdrawn from said body. The body is provided with two individual pockets for the gloves.
This invention relates to an improved pack for presterilized surgeons rubber gloves.
Until recent years surgeons gloves have been packed by the manufacturer in a simple pack, usually an unsealed envelope. It has been the practice for users to remove these from the envelope, which is then discarded. These gloves at this stage are not sterile. The gloves are then prepared for sterilizing by placing them in a pervious bag or envelope either paper or cloth and subjecting them to heat (usually by steam under pressure in an autoclave). This treatment renders them sterile and ready for use.
Lately there has appeared on the market surgeons gloves designated as disposable (single use) gloves. These are available in two forms. One form (commonly known as ready to sterilize) are packed in such a manner that the package with the gloves inside is ready to sterilize by merely placing in an autoclave and subjecting in to heat. The second form is one in which the package and the gloves inside are sterilized by the manufacturer before sale, for example by exposure to gamma radiation. Such package is sealed to prevent the contained gloves from becoming unsterile in storage or handling.
In this second form it is only necessary to Open the pack as received and the gloves are then withdrawn ready for use.
It is of utmost importance that the package in which these sterile gloves are packed will allow the gloves to be withdrawn and presented for use with the least possible risk of contamination whilst so doing. This necessity applies also to the ready to sterilize pack after being sterilized by the user.
There are many and varied types of packs some of which employ a sheet of paper folded in such a way as to enclose the gloves without the need of an outer package but when opened out presents the gloves lying on the inner surface of the paper. Such inner surface if not handled or touched after autoclaving will be sterile. Some packs employ an outer peel back pack enclosing an inner pack. This inner pack is sometimes a paper folder or sometimes an open out cardboard folder.
The disadvantage of these packs is that they all present some risk of the accidental touching of the inner surface of the pack or the gloves themselves when being opened for use.
It is an object of this invention to provide an improved package for surgeons gloves which are sold in a presterilized form.
It is a further object of the invention to provide an improved package for surgeons gloves which will be readily accessible and which will enable the gloves to be withdrawn from the package with a minimum risk of contamination.
A still further object of the invention is to provide a package for surgeons gloves which, while having the above advantages will be relatively low in cost. This is of particular importance in relation to disposable gloves since the Whole of the cost of the package must be considered in connection with a single use.
With a view to achieving these objects the invention provides a pack for surgeons gloves comprising an envelope having a body adapted to receive a pair of gloves, a flap adapted to fold over said body, and an extension of the flap adapted to be folded back over said flap, whereby the pack may be handled without risk of contaminating the gloves, and may be opened without touching any portion of the flap which is likely to be contacted by the gloves when being withdrawn from said body.
Preferably the body is provided with two individual pockets, one for each glove of said pair. The pack may be made from two separate pieces of paper or other suitable material, one of which forms the back of said body, the flap and the extension, while the other forms the front of the body. Alternatively the pack may be made from a single piece of paper, or other material, appropriately folded.
The two pieces of paper or other material may be coated over the whole of their adjacent surfaces or only over those parts which are to be joined together with a sealing material which will allow the joining together of the two pieces by the application of pressure with or without heat.
In a preferred form of the invention the flap is folded over a body, the extension is folded over the flap, and the package as a whole is further folded in two along the common centre line of the body and the flap to permit ready insertion in an outer envelope. The pockets above referred to are located one on each side of the centre line to facilitate the additional folding.
In order that the invention may be more readily understood it will now be described by way of example with reference to a particular embodiment illustrated in the accompanying drawings wherein:
FIGURE 1 is an exploded view showing the parts of the inner package before assembly;
FIGURE 2 is a perspective view showing the assembled inner package and indicating the first step in the folding thereof;
FIGURE 3 is a perspective view illustrating the second step in the folding of the inner package;
FIGURE 4 is a perspective view illustrating the third step in the folding of the inner package;
FIGURE 5 is a perspective view illustrating the completely folded inner package;
FIGURE 6 is an exploded perspective view showing the parts of the outer package before assembly; and
FEGURE 7 is a perspective view of the completed pac The pack of this embodiment is a pack for surgeons rubber gloves in which the gloves 10 and '12 are contained in an inner package 14 which in turn is contained in an outer sealed package 16. The inner package 14 comprises two sheets of paper 18 and 20, a suitable size for sheet 18 being 14 inches x 11 inches (35.56 cm. x 27.94 cm.), and a, suitable size for sheet 20 being 6 /2 inches x 11 inches (16.51 cm. x 27.94 cm.). Sheet 29 is superposed upon sheet 18 with one of its 11 inch (27.94 cm.) sides coinciding with one of the 11 inch (27.94 cm.) sides of sheet 18 and its two 6 /2 inch (16.51 cm.) sides in alignment with the 14 inch (35.56 cm.) sides of sheet 18.
Sheet 20 is then sealed seal having a width of approximately A inch (0.65 cm.) along three of its edges, such edges being those superposed on the edges of sheet 18. In addition a centre seal 24 is formed to join sheet 20, at its centre and at right angles to the 11 inch (27.94 cm.) sides, to sheet 18. When the two sheets of paper have been connected in the manner described the result is a field of paper measuring 14 inches x 11 inches (35.56 cm. x 27.94 cm.) with may be coated with a sealing material which will permit them to adhere to each other by the application of heat with or without pressure. The coating may extend over the whole of the adjacent surfaces or may be restricted to those areas in which seals are to be formed.
If so desired the inner package may be made from a single sheet of paper, folded so that it is of double thickness over the area occupied by the pockets 26.
Disposable. surgeons rubber gloves are always packed having their cuff parts turned back upon themselves for a length of approximately 3 inches (7.62 cm.). This turned back part becomes the inner surface when placed on the hands and is pulled over the cult of the gown.
Whilst care is exercised at all times with sterile gloves,
this turned back cuff, being the inside of the glove, can be touched with little or no risk to the sterility of the outer surface.
The packaging procedure is as follows:
A right and a left hand glove lO and 12 having the cults -36 turned back are placed on sheet 18 and sheet 20 is placed over them. The two sheets are sealed together as hereinbefore described and the gloves are so positioned that the seals may be formed without interference from the gloves lying between the two sheets. They are also positioned so that the edge of the turned back cuffs coincides with the open edge of each pocket. The pack at this stage is a field of paper measuring 14 inches x 11 inches (35.56 cm. x 27.94 cm.) with the gloves having their surfaces except the turned back cuffs enclosed in the pockets 26 and'28.
Sheet 18 is folded back upon itself as indicated in FIGURE 2' at the junction 38 of the flap 32 and the extension 34, the fold being outwards from the surface containing the pockets. Sheet 18 is then folded again across its 11 inch (27.94 cm.) dimension at the junction 40 of the back 30 of the envelope and the flap 32 but towards the surface containing the pockets 26, 28. This fold, which is illustrated in FIGURE 3, causes the gloves to fold at the line of the cuff edges and the cuff edges and the cuffs now lie parallel to the rest of the gloves. The cuffs lie on top of the pockets with the-remainder of the gloves within the pockets. The pack now is folded as indicated in FIGURE 4 at right angles to the pre viously mentioned two folds about line 42 with the extension 34 innermost. brings the inner package to the completed form illustrated in FIGURE and it is now ready to be placed in the outer package 16.
The outer package is composed of two sheets of paper '50 and 52 which after being placed one on top of the other have their four edges sealed together with a sealing material which is of a type which will allow the two sheets to peel apart from each other when an outward (joined) to sheet 18 with a 4' v about 1 inch (2.54 cm.) distant from that edge. The purpose of the boomerang shaped seal is to provide a'c'o'nvenient starting point to pull the sheets of the outer package apart.
The whole pack including the rubber gloves is then sterilized by any suitable means such as -by gamma radiation and this sterile condition will be maintained until the pack is opened.
In order to open the pack for use the two sheets of the outer package are peeled apart and the inner package withdrawn. Only ordinary care in handling is necessary as the gloves and the inner surface of the pack are not accessible to contamination from the hands. The inner package is now placed upon a surface and is first opened out to the condition shown in FIGURE 4. The extension 34 is then grasped to open out the inner package by unfolding the flap 32 at its junction 40 with the envelope portion of the inner package. The gloves are thus presented on a sterile .field which has not been touched in opening. The only portion of the gloves exposed outside the pockets is the cuff portion which can be conveniently grasped to remove the gloves from the pockets ready for placing on the hands. There is no risk of contamination during this operation since the outer surfaces of the gloves are not touched by the hands nor can they come into contact with any portion of the pack which has been touched by the hands.
