a. Field of the Invention
The present invention relates to a glove packing apparatus for packing gloves into a box, and to a method of packing gloves into a box, particularly to the packing of disposable medical gloves.
b. Related Art
The control of infection of patients in hospitals, clinics, and doctors' surgeries has become an ever more pressing concern with the rise of infectious bacteria resistant to multiple antibiotics, in particular methicillin-resistant staphylococcus aureus (MRSA) and Clostridium dificile (C. dificile). In the United Kingdom alone there are thought to be about 5,000 deaths a year from infections caught in hospitals but some experts believe the number could be as high as 20,000.
Disposable medical gloves can help prevent cross-contamination, but a problem arises if external parts of the glove touch the same areas of a dispensing container as have previously been touched by hands which are contaminated with harmful micro-organisms. Such external parts of the gloves can then become contaminated prior to contact with a patient, if these external parts are the fingers or palm area of the glove the likelihood of a patient being contaminated is dramatically increased.
Most gloves used in hospitals and clinics are examination gloves, and these are used in large numbers. Such gloves are supplied not in individual sterile packages, but in relatively inexpensive cardboard dispensing boxes. The size of boxed gloves is an issue owing to the need to minimise the space needed to store gloves, or the size of dispensing apparatus holding boxed gloves.
Because of the enhanced infection control properties the preferred method of dispensing these gloves is by the cuff, so that the user can only remove the gloves from the container by the cuffs rather than by the fingers etc. However in order to remove the gloves by the cuff there is a danger that the users hands will contaminate the edges of the area of the box through which the gloves have to pass, increasing the possibility that any contamination on the hands of the user can then be transferred to the gloves if they touch these areas when removing them from the container.
It is an object of the present invention to provide a means by which during removal of the gloves from the container, the gloves can be prevented from contact with the areas which could have been previously contaminated by user's hands.
It is also an object of the present invention to reduce the packing volume of boxed gloves.
According to the invention, there is provided a glove packing apparatus for packing gloves into a box, the apparatus comprising a receptacle for forming a stack of said gloves to be packed, the receptacle having:
The box may be formed from any suitable material, for example single layer cardboard, stiff paper, or plastic sheet material.
The stack of gloves may be formed manually or automatically, for example by inserting one or more gloves at a time through the opening to build up a stack of gloves supported by the receptacle floor. The perimeter wall can therefore help to define and control the shape of the stack of gloves as this is built up, and ultimately, this will help to ensure that the stack is uniform, with the material of each glove spread out evenly with minimal high spots. Because the floor is moved away from the opening as the stack is built up, the packing operative or packing machine need not reach into the receptacle, but can orient gloves correctly on preceding gloves in the stack, all the while working near the level of the opening to the receptacle. As the stack is built up, the floor is moved away form the opening, so that the working height of the stack continues to be readily accessible but not protruding at any time significantly above the level of the opening. All the while, the perimeter wall continues to stabilise the stack from tipping, while preferably ensuring that the side walls of the stack are, on average straight and parallel with each other.
In a preferred embodiment of the invention, the perimeter wall is fixed and the floor is movable towards and away from the opening. It would, however, alternatively be possible to have the floor fixed, with the perimeter wall being the movable component of the apparatus.
Also in a preferred embodiment of the invention, the floor is an upper surface of a substantially rectangular or square piston that moves within a similarly shaped piston bore.
The receptacle may be inset beneath a surface, for example a worktop that extends around the opening. This can help with the manual sorting and alignment of gloves on the surrounding surface, which can then be easily moved across the surface and into the receptacle. The surface may also help with automatic placement of gloves in the receptacle.
The receptacle will in general have a volume that has a shape that mirrors the internal volume of the box in which the gloves are to be packed. Therefore, it will usually be the case that the perimeter wall extends substantially vertically upwards from the base. The perimeter wall may, however, be discontinuous, as long as this does not adversely affect the containment of the gloves stacked in the receptacle.
In a preferred embodiment of the invention, the perimeter wall has at least one slot, and the apparatus comprises additionally a packing plate adapted to rest on the base of the receptacle. The packing plate is fixed to an extending member that extends through one slot in the perimeter wall. The extending member then can be used to lift or otherwise remove the packing plate from the receptacle when the stack of gloves is complete and ready to be transferred to a box.
To help locate the packing plate correctly on the base, the base may have at least one raised feature in a surface of the base. In a preferred embodiment of the invention, the base has around the perimeter edge, at least one raised feature for locating with one or more corresponding external edges of the packing plate.
Also according to the invention, there is provided a method of packing gloves in a box using a glove packing apparatus, the apparatus comprising a receptacle having an opening and a floor opposite and relatively movable with respect to the opening, the method comprising the steps of:
The transfer of gloves into the box is facilitated by first moving the floor towards the opening to gain more ready access to the stack of gloves and then as gloves are added to stack, moving the floor away from the opening so that the stack of gloves is contained by the receptacle.
The open end of the box in which gloves are to be packed can then be oriented so that this is faces the opening to the receptacle. Optionally, the open end of the box may slot over the outside of the perimeter wall, which can take the form of an extending sleeve. In either case, the receptacle floor can then be moved towards the receptacle opening to move the stack of gloves into the open end of the box.
The box can then be removed from the opening to the receptacle, while at the same time continuing to hold the stack of gloves inside the box. After the box has been removed from the apparatus, the box can be closed, for example by folding flaps over the box opening.
When the apparatus comprises a packing plate that has an extending member, the first step, prior to inserting any gloves through the opening, is to place the packing plate on the movable floor, with the extending member extending externally of the receptacle. Then, when the stack of gloves is ready to be transferred to the box, the extending member can be used to help transfer the stack of gloves into the box. During this process, the packing plate is particularly useful in helping to maintain and compress the gloves fully inside the box.
The open box may have one or more flaps that are moved to close the open end of the box. At least one of these flaps may then be closed while leaving the packing plate in place with respect to said stack of gloves. This helps to compress and contain the gloves in the box until the box can be closed. After at least one flap has been closed, the packing plate can then be removed from the stack of gloves.
In a preferred embodiment of the invention, the apparatus comprises additionally a packing element, the packing element having a lower coefficient of friction than the gloves to be packed. The packing element is then used to cover the packing plate prior to inserting any gloves through the opening, following which the stack of gloves is formed directly on the packing element. The packing element then provides a buffer between the packing plate and the stack of gloves so that the packing plate can slide out of the box without sticking on or dislodging in any way the topmost glove in the stack.
Also described herein is a compression plate for maintaining the alignment of a stack of gloves inside a container, the compression plate comprising a first member and a second member, and a biasing means, said members being joined at a first fold line between said members, wherein: the first member has a second fold line that divides the first member in a first segment and a second segment; —each of said segments is pulled together by the biasing means so that said segments have a tendency to flex along the second fold line and away from the second member.
The first and second members may have corresponding cut outs in the vicinity of the first fold line, said cut outs at (east partially overlapping to permit, in use, gloves to the dispensed through the cut outs.
The biasing means, which may be an elastic band, may engage with engagement features in both the first and second segments of the first member, for example being provided in side edges of the first and second segments.
The first and/or second members are preferably formed from sheet material, for example cardboard, stiff paper or plastic sheet material.
The invention will now be further described, by way of example only, and with reference to the accompanying drawings, in which:
The packing sleeve 2 contains a movable base 20 that provides a floor surface 22. The floor 22 and internal wall surfaces 24, 25 provided by the sleeve halves 10, 11 define a packing receptacle 26 for receiving a stack of gloves 100 to be packed by the apparatus 1, as shown in
The apparatus preferably includes a steel packing plate 28 and a non-woven fabric packing element 30 that are first inserted into the packing receptacle 26. The function of these will be described below.
The base 20 is shown in more detail in
The floor 22 of the base 20 has the same rectangular shape as the sleeve cross-section, but is smaller in both length and width to provide a clear gap 42 between base 20 and the perimeter wall 24, 25. The gap is defined by a rectangular strip 44 that extends downwardly from the floor 22 of the base 20. A lower edge 45 of the strip terminates at an under hanging surface 46 such that the dimension of the gap 42 is increased beneath the strip lower edge 45. The base floor 22 proximate the perimeter edge 51 therefore extends above an overhang feature 44, 4546 in the base 20.
At a distance beneath the strip lower edge 45 at least equal to the width of the rectangular strip 44, the base has a rectangular platform 48 with a rectangular outer profile that matches the shape of the perimeter wall surfaces 24, 25 so that the base platform makes a close sliding fit with these perimeter wall surfaces. The legs 32 and fulcrum 34 then extend downwardly from the base platform 48. The contact between the base platform 48 and legs 32, on the one hand, and the perimeter wall 24, 25 on the other hand, guides the vertical movement between the base 20 and the perimeter wall.
As will be described below, it has been found that this arrangement, in which the floor 22 which is used to support gloves is stepped upwards and inwards with respect to that part of the base which makes a sliding fit of the base 20 within the sleeve 2, greatly reduces or eliminates the chances that any of the supported gloves will become caught or trapped between the movable base 20 and the perimeter wall 24, 25 of the sleeve 2.
The base floor 22 has a raised rim 50 substantially fully around an outer perimeter edge 51 of the floor. The rim is sized so that a main rectangular portion 52 of the packing plate 28 is located within the rim 50 when the packing plate is brought to bear against the base floor 22. The packing plate 28 has at one end of the central rectangular portion 52 a forwards extending tab 54, and at an opposite end a rearwards extending projection 55 with a handle 56 by which the packing plate may more easily be gripped and moved by hand. Both projections 54, 55 make a close sliding fit with the sleeve apertures 14, 15 when the packing place is first inserted into the packing receptacle 26, so that the packing plate is guided into location with the rim 50 of the base floor 22. The rim 50 has a pair of gaps 58, 59 that accommodate the packing plate projections 54, 55 so that the central rectangular portion 52 of the packing plate sits flush against the base floor 22.
Prior to inserting any gloves into the packing recess 26 the packing element 30 is placed directly on the central rectangular portion 52 of the packing plate 28. The packing element is a non-woven fabric or paper slip that has a main rectangular portion 60 the size of which matches that of the packing element rectangular portion 52, and also has a forwards extending tab 62 which covers over the forwards tab 54 of the packing plate 28.
The apparatus preferably contains a stop mechanism (not shown) by which the downwards movement of the base 20 is set to a limit which corresponds to a desired vertical size of stack of gloves. When this is achieved, the stack of gloves 100 is ready for transfer into the cardboard box 64, shown in most detail in
The box 64 is first inserted into a box-like holder or carrier 80 which has an interior volume 79 that matches the shape of the packing box 64. The packing box carrier 80 has a substantially rectangular opening 82 that leads to a box-like receptacle 83 which receives and provides mechanical support to the packing box 64 during the packing process.
When the packing box 64 is seated in the packing box carrier 80, with the box flaps 71-74 splayed outwards, the packing box opening 65 is brought up against the upper edge 66 of the packing sleeve 2, so that the extending outer surface 84 of the packing sleeve nearest the upper edge 66 (see
The lever arm 36 is then use to raise the base 20 and press the stack of gloves 100 up against the inside base of the packing box 64. As air is expelled from the stack of gloves 100, the front and rear packing plate projections 54, 55 come in to proximity with a pair of corresponding magnets 90, 91 situated on forwards and rearwards projection tabs 92, 93 that extend outwards in opposite directions from upper central portions of front and rear walls 94, 95 of the packing box carrier 80. As these projecting portions of the packing plate 28 are formed from steel, the packing plate becomes magnetically clamped to the packing box carrier.
During the upward motion of the stack of gloves 100, outer edges of the stack may drag against the perimeter walls 24, 25 and so be deflected downwards. An important feature of the invention is that the lowermost gloves on the stack are prevented from interfering with or becoming caught between the sliding base 20 and sleeve 2 by the clear gap 42 and overhang 46 above the sliding contact of the base platform 48 and perimeter walls 24, 25.
The packing operator can then lift the boxed gloves and surrounding assembly using the packing plate handle, and then invert this magnetically clamped assembly and place on a nearby working surface, as illustrated in
The first step in closing the box is to fold inwards the pair of flaps 71, 72 on the long sides 75, 76 of the packing box 64, as shown in
The presence of the packing element 30 helps to isolate the sliding movement 96 of the packing plate 28 from the topmost glove 70 so that the stack of gloves 100 is in no way disrupted by the withdrawal of the packing plate.
The packing element 30 is preferably then left in place while the remaining two end flaps 73, 74 are folded inwards. The end flaps 73, 74 each have a pair of side tabs 97 which engage with corresponding side slots 98 at a fold line 99 between the side flaps 71, 72 and the corresponding side panels 75, 76 of the packing box 64 when closed, as shown in
It should be noted that gloves being packed could be folded in half, with cuffs facing the same way, or interfolded in half with cuffs facing in alternate directions. The interior dimensions of the sleeve 2 and packing box can be set accordingly, depending on the desired width and length of the stack of gloves, so that the packed gloves fit snugly within the packing box with minimal wasted packing volume.
As shown in
The packing sleeve 202 is surrounded and partially set into a work surface 250, at a level where the packing plate 228 rests on the work surface as the packing sleeve is filled by hand or by machine with gloves.
The use of the packing plate 228 is similar to that described above. In this embodiment, however, the packing slip 230 is intended to remain in the packed box 280, as shown in
The square outline box of
The gloves in such a square outline arrangement will be over-folded, with the fingers of each glove being folded around the cuff of the preceding glove in the stack, relative to the order of dispensing from the stack. Although not illustrated, this arrangement lends itself to cuff-first dispensing from a dispensing aperture in the box 280, on an opposite side to that having the packing slip, with each glove pulled cuff-first from the dispensing aperture serving to pull the cuff of the next glove to be dispensed out of the dispensing aperture. In this way, each glove to be dispensed can be pulled cuff first from the dispensing aperture without having the user touching the finger portion of each dispensed glove.
The work surface 350 may be supported at a convenient height for a worker by legs or other supports (not shown) and is therefore preferably fixed in place. The packing sleeve 302 is mobile, being mounted, for example, on a wheeled undercarriage (not shown) so that a worker can move the packing sleeve about as desired.
The packing sleeve has a top edge 306 that is the same height as that of the work surface 305. A worker may then gather and fold gloves (not shown) that have been piled on the work surface around the packing sleeve, and then lift or slide these gloves one at a time into the packing sleeve, building up a stack of interfolded gloves above a floor surface 322 of a movable floor 320 within the packing sleeve. Initially, the floor surface is close to but recessed just below the level of the packing sleeve top edge 306. As the stack of glove is built up, the worker lowers the floor surface 322 so that the top of the stack of gloves does not extend above the level of the packing sleeve top edge 306. In this ways, the gloves are aligned vertically by interior walls 325 of the sleeve as the stack is built up.
When sufficient gloves have been inserted into the packing sleeve 302, this is moved out of the recess 303 to a separate work station (not shown), where an empty box 280 in placed over the exposed top end of the packing sleeve, prior to compression of the gloves into the box by the movable floor 320, with the aid of a packing plate 328, followed by closing and sealing of the box as described above.
The reason that the packing process may be conveniently split into two separate stages at different work stations is that it is considerably quicker to pack the box with the stack of gloves than it is to fill the recess within the packing sleeve with a stack of interfolded gloves. Therefore, in a manual packing operation there may be several workers at different work stations responsible for filing packing sleeves with a stack of gloves for every one worker responsible for filling boxes with stacked gloves.
The division of such process steps in a production line having a mobile packing sleeve will also be suited to machine automation, in which a robotics system with computer vision is used to fold and pack gloves into the sleeve, prior to packing boxes with stacks of gloves contained in packing sleeves by a dedicated machine at a separate box packing station. In an automated system, gloves may be brought to the sleeve packing station by a conveyor belt. A glove flipper may be used in conjunction with the conveyor belt to orientate each glove correctly so that a robot arm can pick up each glove and deposit in the sleeve with the cuff and fingers correctly oriented. In such an automated system, the second stage of packing the boxes may be done manually with there being two or more automated sleeve packing stations for each manual box packing station.
The forwards and rearwards segments 108, 109 each have at a portion of each segment closest to the fold line 106 in the upper member 104 a pair of notches 110 in side edges 111, 112 of the card material forming the upper member 104. An elastic band 114 is engaged with each notch 110, and when the upper member 104 is lying flat against the lower member 105, the elastic band is stretched so that the forwards and rearwards segments 108, 109 are being pulled together. The fold line 106 in the upper member 104 forms a hinge between the forwards and rearwards segments 108, 109.
As shown in
The compression plate has in both the upper and lower members 104, 105 similarly shaped, but larger semicircular cut outs 118, 119. The cut out 119 in the lower member 105 is larger than the cut out 118 in the upper member 104, which is larger than the tear away opening 117 in the packing box 64.
When a user opens the packing box 64 and begins to pull gloves 70 cuff first from the opening, the use may touch with his or her fingers the opening 117 in the box. The cut outs 118, 119 below, however, will be protected from potential contamination from a user by the box opening 117 which overhangs the cut outs below.
As gloves are dispensed, space opens up in the box. The elastic band 114 is under tension and able to flex the segments 108, 109 of the upper member 104 about the fold line 106 which therefore acts as a hinge to permit the elastic band to flex the upper member segments into a V-shape, as shown in
As gloves are dispensed, the potential for contamination of the gloves is also reduced owing the overhanging box opening 117 and upper plate cut out 118, as these both protect the lower plate cut out 119, which remains in contact with the topmost glove in the stack of gloves, from any contamination.
The invention therefore provides a convenient way of packing gloves in a box container, and also an effective way of maintaining cleanliness during the dispensing of gloves.
