Description

DISPENSER FOR ROLL OF PLASTIC BAGS

FIELD OF THE INVENTION

Dispensers for rolls of plastic bags and holders for said dispensers for rolls of plastic bags.

BACKGROUND OF THE INVENTION

Plastic bags are used in many places for sanitary separation of foodstuff during shopping for several situations. One such type of plastic bag is plastic bags supplied in a roll. A range of normal uses is for packaging fruit and vegetables, for reducing condensation of cold foodstuff on other items and for separating already leaking products such as paper- wrapped meats or products that spoil other products if they leak, such as eggs. In some areas, plastic bags are used for packaging all groceries.

A common problem with these consumer plastic bags supplied in a roll is that they are scattered throughout a department of a store, and that consumers often have to walk around looking for them thus wasting time and making their overall shopping experience less pleasant. Further, as the user finds the roll, s/he has to pick up the roll and tear off a bag, thereby touching several bags not taken thus increasing the risk of spreading diseases between consumers.

Some shop managers have faced these problems thus ordering welded metal holders from a local smith for the plastic bags. This solves the problem of the consumers not being able to find the bags, when the consumers know the shop. However, several distinct disadvantages present themselves here as well. The holders have to be screwed to the sides of displays or tables, and are immovable afterwards thus reducing the flexibility of the displays of the department. Further, the dispensing openings of these metal dispensers are typically formed from two sheets with convex 'ears' pointing towards each other. When drawing a bag, users have to jerk at the bag at the right moment for an 'ear' to hit the perforation line between two bags for the bag to come loose from the roll. This is a complicated movement that often results in tearing the first bag or rolling out several bags from the roll, either of which requires the consumer to use both hands to correct the error, to concentrate, and may leave waste in the form of bags. As much as 30% of the bags of a roll may be wasted this way.

GENERAL DESCRIPTION

The object of the invention is to solve some of the above-mentioned problems. In accordance with the invention, there is supplied a dispenser for a roll of disposable plastic bags, the dispenser comprising a housing for said roll, holding means for fixating said roll relative to said housing, a dispensing opening for consecutive dispensing of plastic bags from said roll, while said roll is affixed by said holding means, wherein said dispensing opening is formed of two adjacent surfaces in between which, the plastic bags can be dispensed and held in position.

Thereby, a sanitary and easy plastic bag dispensation is achieved. It is not convenient during shopping to instruct consumers in correct use of plastic bag dispensers. Therefore, to achieve correct use it is important that the use is easy and intuitive. By supplying the above-mentioned dispenser, the user is not forced to touch the entire roll of bags. Even further, mishaps are less likely to happen as the dispensing opening is narrow enough to touch both sides of the plastic bag being dispensed, even if the quality of perforations between two bags is bad and the two bags are more firmly attached than usual, or if the user is careless in using the dispenser.

In an embodiment, the adjacent surfaces are further contiguous supporting surfaces, where said contiguous surfaces are s-curved as seen collinear to a line running through the width of said dispensing opening.

Thereby, by the surfaces being s-shaped, even more support is supplied to the plastic bag partly dispensed and located partly through the dispensing opening. Further, it is ensured that not only point-contact is made between the plastic bags to be dispensed and the surface, but that contact is made along a longer distance thus increasing friction and improving holding power of the dispensing unit.

By two surfaces being contiguous is meant that they are brought into near-contact or contact, and that a plastic bag placed therebetween can be maintained between the two surfaces, for example against the force of gravity, by the force of friction produced by the two surfaces onto the plastic bag.

In an embodiment, one said adjacent surface has a tip at the end of the dispensing opening being farthest from the holding means, the tip being angular to said supporting surface and extending in a direction towards said other adjacent surface. Thereby, when dispensing plastic bags, the tip will engage with the perforations to rip the plastic bag free from the next plastic bag. In an embodiment, the tip is at a right angle to the adjacent surface.

In an embodiment, an adjacent surface tapers off towards the middle of the dispensing opening. Thereby, aid is supplied for a user during drawing a bag, where it is easy to see and adjust for the user inadvertently drawing a bag in a skewed manner. Further, the middle of an adjacent surface may function to engage with the perforations to rip the plastic bag free from the next plastic bag.

In an embodiment, the dispenser is extruded or moulded in a plastic material. Thereby, a cheap and easy way to mass-produce a standard solution is achieved. The plastic may for example be ABS, ETPU, HDPE, LCP, CDPE, LLDPE, PA, PBT, PC, PEEK, PEI, PET, PETG, PMMA, POM, PP, PPE, PS, PPS, PS, PSU, TPE, TPV or TPU, or a combination of any of these.

In an embodiment, the housing comprises a first cover extending on a first side of the holding means and a second cover extending on a second side of said holding means, the first and second covers being connected to a pivot stem and individually rotatable about said pivot stem. Thereby, the housing is openable, and the shop personnel may easily adjust and change the roll when the inserted roll is emptied or the next bag has fallen out of order, such as being drawn out one side of the dispensing opening. In an embodiment, the holding means is movable about the pivot stem independently from the two parts of the housing. Thereby, easy changing of rolls of plastic bags is achieved.

In an embodiment, the housing has at least a horizontal holding interface allowing mounting a holding stem at a right angle relative to the dispensing opening and a vertical holding interface allowing mounting a holding stem parallel to the dispensing opening. Thereby, the orientation of the dispenser can be adjusted based on the exact setup of the department or shop having the dispenser as well as any change in layout of the department occurring over time.

In an embodiment, the horizontal holding interface comprises an interface member for engagement with said pivot stem and/or housing in one end and engagement with a holding stem in an opposite end, where the vertical holding interface comprises the housing adapted for substitution of at least part of said pivot stem for said holding stem.

In an embodiment, the dispenser is adapted to be oriented horizontally by using an interface member having a gear-tooth mechanism for engagement with the housing. The gear-tooth mechanism may engage any part of the housing, such as either cover or the holding means.

In an embodiment, the angle between the holding interface and the housing can be controlled when inserting the pivot stem into the holding interface. Thereby, the angle of the dispenser can be adjusted to the needs of the individual shop, department or display. In an embodiment, the sidewalls of the housing covers are adapted to snappingly engage with tongues having knobs on one sidewall and holes for the knuckles on the corresponding sidewall of the opposite cover. Thereby, easy access can be achieved to the insides of the housing and to the roll.

In an embodiment, the invention relates to a clamp mount for releasably fastening of a bag dispenser to an edge of a planar element comprising a first jaw and a second jaw for mounting on opposite sides of said planar element, a fastening member for releasably connecting said two jaws thus supplying a releasable fixation to said planar element, wherein the first jaw is supplied with an adjustment aperture having a varying average diameter, said aperture being smallest on the surface facing away from said second jaw, the clamp mount further comprising a mounting base for mounting in said adjustment aperture, the mounting base having a mounting opening for mounting a holding stem, the mounting base having a mounting opening normal to the plane of the adjustment aperture and a mounting opening parallel to the plane of the adjustment aperture. Thereby, the clamp mount may be mounted onto a variety of surfaces thus allowing the dispenser to be releasably fastened to most edges and allowing flexible use that can change as the shop, department or display changes.

In an embodiment, the fastening member is a rod bent in a U-shape with two legs, where the spring angle between the U and the legs is acute. Thereby, an improved fastening pressure distribution is achieved over the clamp mount. In an embodiment, the spring angle is between 70° - 89°, preferably 85°.

In an embodiment, the orientation of the mounting base is configurable relative to said first jaw when fastening said clamp mount around an axis being co-linear with the central axis of said adjustment aperture. Thereby, the dispenser may be fastened to edges of various angles.

In an embodiment, the mounting aperture and mounting base engage by gear tooth engagement. Thereby, secure and high-fidelity adjustment is achieved. In an embodiment, the gear tooth engagement is in 5° - 30° increments, such as preferably 15° increments.

In an embodiment, the mounting base is supplied in a two-component form, where a part of the lower surface is in an anti-skid material such as latex or rubber. Thereby, secure attachment to the planar element is achieved. Further, this reduces scratching. In an embodiment, the second jaw has an upper surface that is at least partly supplied in an anti-skid material such as latex or rubber. Thereby, secure attachment to the planar element is achieved. Further, this reduces scratching.

DETAILED DESCRIPTION OF THE DRAWINGS

In the following, the invention is described in detail through embodiments thereof that should not be thought of as limiting to the scope of the invention.

Fig. 1 illustrates a dispenser 100 for a roll 150 of disposable plastic bags. The dispenser 100 comprises a housing 110 defined by a first cover 101 and a second cover 102 partly encapsulating said roll 150. Said covers 101 , 102 comprise integral end plates 101 a (101 b- d not shown). The first cover 101 and the second cover 102 are rotatably connected through a pivot point/hinge system 105, such that said covers 101 , 102 may be opened around said hinge system 105 thereby allowing access to the housing 110. The hinge system 105 is described in more detail when considering Fig. 5. Preferably, at least the first cover 101 comprises a carving 112, such that the user may observe the contents of the housing 1 10.

The first 101 and second cover 102 are shaped such that they form a housing 110 suitable for a roll 150 of disposable plastic bags. Further, said covers 101 ,102 are shaped such that a dispensing opening 104 is formed opposite the hinge system 105. This means that each cover 101 ,102 may be said to be shaped like a sigmoid function or an S-curve, whereby said covers 101 , 102 are contiguous most distant the hinge system 105. The first cover 101 comprises a first inner surface 201 , and the second cover 102 comprises a second inner surface 202. Said first inner surface 201 and said second inner surface 202 are adjacent and contiguous supporting surfaces. The dispensing opening 104 formed by the contiguous inner surfaces 201 ,202 is of a size, such that a single plastic bag 151 is fixated or held in place within said dispensing opening 104. The ends of the covers 101 , 102 most distant the hinge system 105 are shaped such that they converge or taper off towards a common central point 1 13. Thereby, the user may easily grab the plastic bag 151 held in place by the dispensing opening 104 due to corners 151' of said plastic bag 151 being free from said dispensing opening 104. A tip 103 is arranged on the second cover 102 at said common central point 113, such that said tip 103 may engage with a tearing or perforation defining the individual plastic bags 151 of the roll 150 of disposable plastic bags. The tip 103 is bent and points towards the first cover 101 , thereby preventing unintentional escape of plastic bags 151 from the roll 150. Further, the tip 103 eases the tearing off of individual plastic bags 151 from the roll 150, such that the user may easily tear off a plastic bag 151. When a plastic bag 151 has been torn off, a subsequent plastic bag is guided into the dispensing opening 104 due to the sigmoid shape of the first 101 and second cover 102.

The end plates 101 a of the covers 101 , 102 comprise a locking mechanism 120 preventing unintentional rotation of the covers 101 ,102 around the hinge system 105. The locking mechanism is described in more detail when considering Fig. 2.

The dispenser 100 may be mounted on a table 1 using a clamp mount 300. Said clamp mount 300 comprises a first jaw 310 and a second jaw 320 held in place using a fastening rod 305 shaped to fit a groove within the first jaw 310 and through-going holes within both the first jaw 310 and the second jaw 320, such that a nut 326 may fasten the clamp mount 300 onto the table 1. The first jaw 310 comprises an adjustment aperture for mounting a mounting base 330, said mounting base 330 being adjustable in said adjustment aperture. A holding stem 340 is inserted into an opening in the mounting base 330 and further into an opening in the hinge system 105 of the dispenser 100. The holding stem 340 is a rigid element, such that the dispenser 100 is held in place relative to the clamp mount 300.

Fig. 2 illustrates the dispenser 100 in an open configuration without a roll of disposable plastic bags thereby exposing the interior of the housing 1 10. The first cover 101 is shown to comprise a first and a second integral end plate 101 a, 101 b, and similar, the second cover 102 is shown to comprise a third and a fourth integral end plate 102a, 102b. The end plates overlap each other pairwise, that is the first end plate 101 a overlaps the third end plate 102a. Likewise, the second end plate 101 b overlaps the fourth end plate 102b. Each set of overlapping end plates comprises a locking system 120. The locking system comprises a knob 222a (222b not shown) arranged on a tongue 223a, 223b on the third 102a and second 101 b end plates respectively, and an eye 221a, 221 b arranged on the first 101 a and second 102b end plates respectively. Thus, the locking system 120 is interchanged, but it may be parallel in the two sets of overlapping end plates. A guide 224 may be carved partly into the end plates comprising the eye 221 a, 221 b for reducing the friction of the knob 222a, 222b against said end plates.

The locking system 120 is activated by the knob 222a, 222b engaging the eye 221a, 221 b by rotating the first 101 and second cover 102 around the hinge system 105, such that a pairwise overlap of the integral end plates occurs. The tongue 223a, 223b is elastically resilient through a groove 225a, 225b cut in the respective end plate. By the tongue 223a, 223b being elastically resilient, the knob 222a, 222b arranged on it may be pressed inwards towards the housing 110 when engaging, followed by said knob snapping into the respective eye 221a, 221 b, when sufficient overlap of the end plates has occurred. Unlocking the locking system is done by pressing the knob 222a, 222b inwards, followed by rotating the first 101 and second cover 102 around the hinge system 105, whereby said knob disengages the respective eye 221 a, 221 b.

A holding means 260 is arranged within the housing 110. Said holding means 260 comprises holding protrusions 261 a, 261 b protruding into the housing 1 10 and arranged to secure the roll of dispensable plastic bags (not shown). The holding protrusions 261 a, 261 b are rotatably connected to the holding means 260, such that the roll 150 of dispensable plastic bags may rotate with limited friction within the housing 110. The holding means 260 further comprises parts of the hinge system 105 which is described in detail when considering Fig. 5. Fig. 3 illustrates the dispenser 100 from various angles and in different configurations. Reference numerals are identical to previous numbering. Figs. 3A-B show the configuration, wherein the dispenser 100 is arranged vertically, while Figs. 3C-D show the configuration, wherein the dispenser 100 is arranged horizontally. The configuration is determined by the use of the hinge system 105 which is described in more detail when considering Fig. 5. The first cover 101 cover and the second cover (not shown) each comprises a set of cover knuckles 107. Said cover knuckles 107 constitute a part of the hinge system 105. A pin 417 penetrates the set of cover knuckles 107, said pin 417 constituting a second part of the hinge system.

Fig. 4 illustrates the clamp mount 300 in an exploded view in general comprising the fastening rod 305, the first jaw 310, the mounting base 330, and the second jaw 320. A table 1 may be inserted between the first 310 and the second jaw 320, such that the clamp mount 300 is fastened on said table 1. The table 1 may be any other planar surface, such as a box or a plate. The fastening rod 305 comprises a U-shaped section 306 and two threaded ends 307 bent by an angle of preferably 85°, such that the angle formed between the plane of the U-shaped section 306 and the plane formed between the parallel threaded ends 307 is acute. Thereby, when fastening the clamp mount 300, a spring force is exerted onto the first 310 and second jaw 320. The first jaw 310 comprises an adjustment aperture 313 for receiving the mounting base 330, a fastening groove 315 for receiving the fastening rod 305, a set of fastening holes 317 for receiving the threaded ends 307, and a screw hole 316 for optionally screwing the first jaw 310 onto a surface. The adjustment aperture 313 comprises a first set of equiangularly spaced teeth 318 arranged in the circumference of said adjustment aperture 313. Said first set of equiangularly spaced teeth 318 is for engaging with a corresponding second set of equiangularly spaced teeth 338 in the mounting base 330. Thereby, the mounting base 330 may be rotated in minor steps depending on the desired configuration of the dispenser 100 while being securely fastened. Alternatively, the equiangularly spaced teeth 318,338 may be substituted by polygons, whereby the mounting base 330 may be rotated according to the amount of corners in the polygon. The mounting base 330 further comprises a first mounting hole 331 and a second mounting hole 332 for insertion of the holding stem 340. Thus, the diameter of the holding stem 340 matches the diameter of the first 331 and second mounting hole 332. Preferably, the mounting holes 331 ,332 comprise a protrusion (not shown) to engage with a corresponding indentation (not shown) in the holding stem 340 for prohibiting rotation of said holding stem 340 within said mounting holes 331 ,332. The underside 339 of the mounting base 330 comprises an anti-skid material for partly preventing skid of the clamp mount 300, partly for protecting the surface from marks. The second jaw 320 comprises a primarily flat surface 322 for aligning parallel to a surface of e.g. a table 1 , a jaw collar 321 for aligning the clamp mount 300 to the edge of the table 1 , and a set of jaw holes 327 for receiving the threaded ends 307 of the fastening rod 305. Thereby, the fastening rod 305 penetrates the prepared jaw holes 327 in the first jaw 310 and the second jaw 320 and is subsequently fastened using a nut 326 for each threaded end 307.

Fig. 5 illustrates the hinge system 105. The dashed line 400 illustrates the assembly procedure. Said hinge system 105 comprises a holding interface 401 comprising a hollow opening 401a for receiving the holding stem 340 (not shown) and a jagged end 401 b comprising a through-going opening 401 c. The hollow opening 401 a has a diameter matching the diameter of the holding stem 340 and preferably comprises a protrusion (not shown) within the opening for engaging with an indentation (not shown) in the holding stem 340 for preventing rotation. The holding interface 401 is for insertion into a holding gap 402 formed between a set of holding knuckles 407 mounted on the holding means 260. Thus, the width of the jagged end 401 b of the holding interface 401 matches the width of the holding gap 402. Said holding gap 402 further comprises a jagged surface 411 corresponding to the jagged end 401 b of the holding interface 401. A filler 499 may be substituted into the holding gap 402 instead of the holding interface 401 , in case a configuration of the dispenser 100 renders said holding interface 401 unnecessary. The filler 499 comprises a jagged surface 499b identical to the jagged surface 401 b of the holding interface 401.

In order to assemble the hinge system 105, the cover knuckles 107 of the first 101 and second cover 102 are arranged adjacent to each other and further adjacent to the holding knuckles 407. The knuckles 107,407 are hollow, thereby allowing insertion of a pin 417. The pin 417 comprises a first pin 417a and a second pin 417b. The first pin 417a and second pin 417b comprise a first collar 418a and a second collar 418b for limiting the penetration depth into the plurality of knuckles 107,407. The second pin 417a further comprises a stepwise reduction of its width. The first width 427a corresponds to the inner diameter of two cover knuckles 107 and one holding knuckle from the set of holding knuckles 407. The second width 427b corresponds to the diameter of a first holding knuckle collar 408a. The third width 427c corresponds to the diameter of a second holding knuckle collar 408b (not shown). Thus, on insertion of the second pin 417b, it penetrates two holding knuckle collars 408a and 408b (not shown) arranged within the holding knuckles 407 thereby reinforcing and stabilising the hinge system 105. The first pin 417a has the first width 427a corresponding to the inner diameter of the cover knuckles 107 and one holding knuckle from the set of holding knuckles 407. When assembled, the second pin 417b penetrates the through-going opening 401c of the holding interface 401 thereby fixating said holding means 260 to the hinge system 105. In a vertical configuration of the dispenser 100, the user may substitute the first pin 417a with the holding stem 340 (not shown) having similar diameter. The interior of the holding knuckle 407 in contact with the first pin 417a or the holding stem 340 may comprise a protrusion 434 corresponding to an indentation (not shown) in the holding stem 340 thereby preventing rotation. The holding means 260 is arranged relatively to the hinge system 105 and the housing 110 of the dispenser 100 such that the holding protrusions 261 a, 261 b of said holding means 260 are arranged within the housing 110. That is, the holding knuckles 407 are arranged outside the housing 1 10, whereas the holding protrusions 261a, 261 b are arranged inside said housing 1 10.

Fig. 6 illustrates side views of different configurations of the clamp mount 300. In Fig. 6A, the clamp mount 300 is mounted on a vertical surface 1 a, e.g. the edge of a box. In this configuration, the holding stem 340 is arranged vertically and is inserted into the second mounting hole 332 of the mounting base 330. A protrusion 334 within the first mounting hole 331 is visible, said protrusion 334 being for engaging with an indentation (not shown) in the holding stem 340 for preventing rotation.

In Fig. 6B, the clamp mount 300 is mounted on a vertical surface having a 30° sloped edge 2b. In order to keep the holding stem 340 in a vertical configuration, the mounting base 330 is rotated within the first jaw 310. The rotation is secured by using the first set of equiangularly spaced teeth 318 (not shown) arranged in the adjustment aperture of the first jaw 310 and the second set of equiangularly spaced teeth 338 (not shown) arranged in the mounting base 330, said sets of equiangularly spaced teeth 318,338 interlocking in the desired angle. The equiangularly spaced teeth 318,338 may be spaced in steps of 5° or 10° thereby allowing adjustment of the mounting base 330 and thereby the holding stem 340 in alike steps.

In Fig. 6C, the clamp mount 300 is arranged on a horizontal surface 1. The clamp mount 300 clamps the edge 2 of the surface 1. The clamp mount 300 is fastened to the surface 1 using the fastening rod (not shown) and the nuts 326. The holding stem 340 is arranged vertically in the first mounting hole 331. In this configuration, it is evident that the rotation of the mounting base 330 relative to the adjustment aperture 313 (not shown) of the first jaw 310 is indifferent. In Fig. 6D, the clamp mount 300 of Fig. 6C is seen from another angle. There, the relation between the surface 1 , the first jaw 310 and the second jaw 320 is exposed in detail. REFERENCE NUMBERS
