Definitions
- the invention relates to beverage cup lids, to barriers for shielding drinking apertures of beverage cup lids, the hygienic supply of beverage cup lids, and the application of barriers to lids during a manufacturing process and prior to delivery to a café or the like.
- Beverages such as coffee, tea or the like are often sold in disposable cups provided with lids.
- Some lids include a drinking aperture through which a product located therein may be consumed whilst the lid remains in place. Some lids include a projecting spout terminating in the drinking aperture and about which the consumer's lips may be pursed. The latter form of lid is sometimes referred to as a “sipper cup lid”.
- Baristas and staff are typically faced with coordinating a multitude of tasks under time pressure. Beyond operation of a coffee machine, for example, they must also handle milk cartons, money, food items, dirty dish cloths and other potentially unsanitary items. Within this challenging work environment it is unsurprising that a barista's hands may be unsanitary.
- a beverage cup lid having a generally planar central portion and a rim surrounding and extending away from said central portion;
- the barrier member overlies a region, about the drinking aperture where a consumer's lips contact the lid whilst drinking.
- the barrier member is a sticker, the sticker having a tab to peel said sticker away from at least a portion of said lid to expose said drinking aperture.
- the barrier member extends at least partly over the drinking apertures, rim and central portion.
- a method of producing a beverage cup lid including:
- the step of selecting the barrier from a supply of barriers including the step of selecting the barrier from a supply of barriers.
- the step of applying the barrier to said shaped portion includes pressing the barrier against the shaped portion.
- the step of forming the shaped portion includes thermoforming a portion of a sheet of material.
- FIGS. 1 a , 1 b to 4 a,b show production steps producing a lid for a beverage cup of an embodiment of the present invention
- FIGS. 5 a and 6 a show barrier members of the present invention.
- FIGS. 5 b and 6 b show the barrier members of 5 a , 6 a , applied to a lid.
- shielded lids 1 are produced during a manufacturing process (see FIGS. 1 a , 1 b to 4 a , 4 b ) and prior to delivery to a café or the like.
- the manufacturing process in a preferred embodiment includes moving a sheet of material in the form of strip 2 along a production line 4 including through production stations 6 , 8 and 10 . It should however be understood that the process could include any number of production stations.
- the strip 2 is typically produced through an extrusion process and supplied to the first production station 6 in a hot, pliable, form.
- the strip 2 could be manufactured on site or brought from a third party. However, it should be understood that strip 2 could be produced using various typical sheet forming methods.
- the strip 2 is thermoformed to create a shaped portion 12 within the strip 2 .
- the thermoforming is vacuum forming, that is, the strip 2 is sucked onto a male die.
- the material 2 may be supplied in solid form, in a roll and heated to be made pliable before application or the like.
- the lids 12 could also be made through injection moulding.
- the shaped portion 12 (i.e. lid) is moved to the second station 6 (see FIGS. 1 a , 1 b ).
- Station 6 is a punching station at which the shaped portion 12 is sandwiched between a punch tool 6 a and a complementary anvil 6 b to form a drinking aperture 12 a , vent holes and the like.
- the shaped portion 12 is moved to the third station 8 (see FIGS. 2 a 2 b ).
- Third station 8 is a barrier application station at which a barrier 14 is applied to the formed portion 12 (see FIGS. 2 a , 2 b ).
- Station 8 includes a sticker application tool 8 a .
- the tool 8 a includes a main body 8 b referred to as a “mask” integrally formed with a shaft 8 c projecting therefrom.
- a collar 8 d embraces the shaft 8 c and carries vacuum fingers 8 e which slidingly project through apertures (not shown) through the mask 8 b in a direction parallel to the shaft 8 c.
- FIGS. 1 a , 1 b show the tool 8 a in its barrier selecting position in which the fingers 8 e project beyond the mask 8 b to suctionally engage the face of a barrier 14 to a dispenser 8 f.
- the tool 8 a is moved to a sticker applying position of FIGS. 2 a , 2 b .
- the tool 8 a rotates from a horizontal barrier selecting position to a vertical barrier applying position.
- the sticker could at this stage or later applied include advertising or the like.
- the tool 8 a In the position of FIGS. 2 a , 2 b the tool 8 a is aligned with the shaped portion 12 sitting at station 8 . The tool 8 a is then relatively advanced towards the shaped portion 12 (in this case lowered) to press the barrier 14 onto the shaped portion 12 . As the tool 8 a advances toward the portion 12 , the barrier 14 , carried by the fingers 12 e , contacts the shaped portion 12 (see FIGS. 3 a , 3 b ). With continued advancement of the tool 8 a , the collar 8 d and fingers 8 e remain stationary whilst the main body 8 b continues on the production line 4 . The main body 8 b has a face (not shown) shaped to complement the shaped portion 12 so as to conformably apply the barrier 14 to the shaped portion 12 .
- the station 10 is a trimming station including a cutter 10 a and anvil 10 b .
- the anvil 10 b has a central bore and is lowered into contact with the strip 2 so as to encircle the shielded shaped portion 12 .
- the cutter 10 a has a circular cutting edge complementary to the bore of the anvil 10 b and is upwardly driven to make a circular cut severing the shielded shaped portion 12 from the strip 2 .
- a shielded lid 1 is formed, although of course its formed plastic portion still fits the description of “a shaped portion” 12 .
- the sticker 14 however can be dressed before trimming or after trimming.
- the newly formed lid 12 is driven to engage the underside of an overlying previously formed lid 12 .
- the newly formed shielded lid 12 is added to the stack of lids 12 .
- the newly formed shielded lid 12 nests within the upwardly adjacent lid 12 as shown in the Figures.
- FIGS. 5 a , 5 b and 6 a , 6 b The shapes of the described exemplary lids 12 and barriers 14 are better shown in more detail in FIGS. 5 a , 5 b and 6 a , 6 b.
- the shaped portion 12 which is to become a lid 12 , includes an upwardly converging conical exterior 12 c surrounding a circular well or central portion 12 d dimensioned to receive the bottom of a cup (not shown).
- the well 12 d has an upwardly diverging conical side wall 12 b .
- the wall 12 c and the wall 12 b of the well 12 d are connected about the upper peripheries by a rim 12 e .
- the aperture 12 a is spaced about the rim. There may be one or more apertures.
- the wall 12 c is surrounded by a circular flange 12 f shaped to engage the rim of a cup.
- the flange 12 f includes an outwardly bulbous portion (not shown) defining an annular recess (not shown) dimensioned to receive a more or less toroidal rim of a cup.
- the bulbous portion is shaped to embrace the rim of the cup and defines an annular nose which in use underlies the rim of the cup to hold the lid 12 in place as per a standard coffee cup lid.
- Below the nose is a short downwardly diverging conical skirt (not shown) which acts on the rim of the cup to provide a lead in when fitting the lid 12 to the cup.
- lids 12 When the lids 12 , or shaped portions which are to become lids 12 , are stacked an interior of the skirt rests on an exterior of the bulbous portion defining a circular line of contact and in turn defining the pitch at which the lids 12 are stacked.
- the barrier 14 in the example of FIGS. 5 a and 6 a , is a sticker predominantly consisting of a thin pliable piece cut from a sheet of material.
- the sticker may be formed of paper treated with a suitable adhesive or any other suitable material.
- the sticker 14 in an embodiment is about twice as long as it is wide when viewed in plan.
- One end of the sticker terminates in a straight edge 14 a which runs transverse to the sticker's length.
- a central portion 14 b is positioned towards the other end of the sticker 14 .
- the central portion 14 b can be of any shape and size.
- a straight bridging portion 14 c runs parallel to the sticker's length and connects a rectangular body of material defining the edge 14 a to the central portion 14 b .
- On either side of the bridging portion 14 c a portion 14 d projects from the body of material.
- Each portion 14 d has an outer edge 14 g and an inclined edge 14 h .
- the inclined edges 14 h diverge from each other in a direction away from the edge 14 a and thus a respective opening 14 e is defined between each portion 14 d and the bridging portion 14 c .
- a pull tab 14 f extends from the circular portion 14 b in a direction parallel to the length of the sticker 14 .
- the sticker 14 would be made of a single piece of material and could include separable slits, perforations, scores or the like.
- the sticker 14 could be made of a biodegradable material.
- the stickers 14 may be applied by heat or by heat shrinking or vacuum shrinking. Heat and heat shrinking eliminates the need for cuts and perforations as it molds the plastic sticker 14 around the contours, however, slight scores may be required. It also eliminates the need to make stickers 14 in different shapes to suit different shape lids 12 .
- the stickers 14 may also be applied without heat and/or only with a downward pressure and use of an adhesive or the like. In this regard, the section about the aperture would utilise food grade adhesive or the like and leave no residue about the aperture.
- the sticker 14 may cover the entire mouth area or the whole lid 12 .
- the sticker 14 would be drawn using a vacuum, but there can be other ways to draw the stickers, like a roll over the lids that by pressing down, will apply the sticker 14 and release the sticker 14 from the roll, or a roller that rolls over the lids 12 and applies the sticker in a rolling motion.
- the tab 14 f is generally positioned towards the center of the lid 12 so the pulling motion is down, pulling the tab 14 f upwards may cause the lid 12 to pop off the cup.
- the sticker 14 can be made using any thin material, whether plastic, vinyl, paper etc. The sticker 14 will be adhered back onto the side of the cup to prevent littering.
- the edge 14 a follows the circular lower extent of the surface 12 c and the central portion 14 b is adhered to the floor of the well 12 d such that the bridging portion 14 c directly overlies the drinking aperture 12 a and runs down the conical wall of the well 12 d .
- the sticker 14 is deformed to close the openings 14 e and the inclined portions 14 d overlie the conical wall of the well 12 d.
- the central portion 14 d serves to shield the floor of well 12 d , which may contact the consumer's nose. It is also a convenient place for displaying images, advertising, trademarks, and/or other markings. By way of example the markings may be logos or advertisements. A business, such as a cafe or coffee supplier, might pay for their identity to be applied to the spot.
- No part of the sticker 14 overlies the flange 12 f , such that when stacked the circular line of contact between the portion 12 g and an upwardly adjacent lid 12 is not broken by the sticker 14 .
- the lids 12 may be efficiently stacked to form a straight vertical stack 30 which is stable.
- Such stacking qualities are of course highly desirable to suit packaging and transport and easy handling by the barista or other café staff.
- a stack 30 of shielded lids 12 can be packaged in a tube of pliable plastic material (not shown) to shield them from contamination between the manufacturer and the barista or during use at a café.
- the barista may then receive the sealed package and simply remove the stack from the package and transfer it to a convenient location.
- the stack 30 may be placed atop a coffee machine or the like, in which case the stability of the stack is highly desirable so that the stack does not fall over in response to machine vibration or the like.
- the sticker 14 in a preferred embodiment has strategically placed points of adhesive—in this case, one adjacent each end of the edge 14 a and one adjacent the pull tab 14 f .
- the degree of adhesion is selected to resist inadvertent removal of the sticker 14 from the shaped portion 12 whilst permitting removal of individual stickers 14 from the dispenser 8 f and removal of the sticker 14 by the consumer.
- the sticker 14 preferably covers the hole or aperture 12 a and acts to stop liquid located within the cup from splattering through the hole when a consumer is walking or when pressing on the sides of the cup.
- the sticker 14 can also be applied to the side of the cup once peeled from the lid to become a “cup print” or advertising as well as to prevent litter.
- the pull tab 14 f is positioned to be grasped and pulled horizontally towards the edge 14 a and then, without releasing the pull tab 14 f , to be pulled downwardly to peel the material defining the edge 14 a from the conical surface 12 c .
- This positioning of the pull tab 14 c desirably allows for the removal of the sticker 14 in substance without upward force being applied, such that the likelihood of inadvertently pulling the lid 12 from the cup is reduced.
- a shielded lid 12 is manufactured and supplied to the retailer (e.g. café or the like) in a fully assembled configuration. This ensures that a barista, café staff, delivery man or the like has not touched the drinking aperture prior to use by a consumer. This will be of great reassurance to many consumers and a significant advance in hygiene.
- the orientation and scale of the production line may also be varied. Multiples of the described work stations may be arranged in parallel or series.
- an extruder horizontally feeds a sheet of hot pliable material to a drum having a horizontal axis about which it is rotatable, wherein the drum includes 7 rows of 8 vacuum forming dies along its length.
- the drum rotates continuously forming shaped portions as it carries the sheet material from about a 2 o'clock to about a 7 o'clock position. At about the 7 o'clock position the sheet peels away from the drum and moves downwardly through 7 parallel vertically-oriented variants of the production line 4 .
- the lids 1 may be of various shapes and sizes, including different spout shapes, etc. Indeed the lids 1 may be spoutless.

Abstract
A beverage cup lid (12) having a generally planar central portion and a rim surrounding and extending away from said central portion. At least one drinking aperture (12 a) located substantially adjacent said rim and adapted to permit liquid to flow through said lid. A barrier member (14) overlies said drinking aperture. The barrier member (14) being applied to the lid during a manufacturing process and removable by an end user to permit drinking via the drinking aperture.
Description
- The invention relates to beverage cup lids, to barriers for shielding drinking apertures of beverage cup lids, the hygienic supply of beverage cup lids, and the application of barriers to lids during a manufacturing process and prior to delivery to a café or the like.
- Beverages such as coffee, tea or the like are often sold in disposable cups provided with lids.
- Some lids include a drinking aperture through which a product located therein may be consumed whilst the lid remains in place. Some lids include a projecting spout terminating in the drinking aperture and about which the consumer's lips may be pursed. The latter form of lid is sometimes referred to as a “sipper cup lid”.
- Cafes, restaurants and the like are often busy and cramped. Often the lids and cups are stored separately and the lids applied to the cups by the barista or other staff.
- Baristas and staff are typically faced with coordinating a multitude of tasks under time pressure. Beyond operation of a coffee machine, for example, they must also handle milk cartons, money, food items, dirty dish cloths and other potentially unsanitary items. Within this challenging work environment it is unsurprising that a barista's hands may be unsanitary.
- These potentially unsanitary hands then routinely come into contact with the drinking apertures of the lids when applying the lids to the cups, particularly in the case of sipper cups with their projecting drinking apertures. Typically, a barista would place the lid on a cup and using his/her hand push the lid down onto a cup rim with the palm pushing down and coming in contact with the aperture and spout. It is of course the drinking aperture and spout which is brought into intimate contact with the consumer's mouth causing a health risk if the surfaces are dirty.
- There is a need to address these health risks in a simple, easy and inexpensive way.
- It is an object of the present invention to substantially overcome or at least ameliorate one or more of the disadvantages of the prior art, or to at least provide a useful alternative.
- There is disclosed herein a beverage cup lid having a generally planar central portion and a rim surrounding and extending away from said central portion;
-
- at least one drinking aperture located substantially adjacent said rim and adapted to permit liquid to flow through said lid;
- a barrier member overlying said drinking aperture;
- the barrier member being applied to the lid during a manufacturing process and removable by an end user to permit drinking via the drinking aperture.
- Preferably, the barrier member overlies a region, about the drinking aperture where a consumer's lips contact the lid whilst drinking.
- Preferably, the barrier member is a sticker, the sticker having a tab to peel said sticker away from at least a portion of said lid to expose said drinking aperture.
- Preferably, the barrier member extends at least partly over the drinking apertures, rim and central portion.
- There is further disclosed herein a method of producing a beverage cup lid including:
-
- forming a portion shaped to fit a cup;
- forming a drinking aperture in said shaped portion;
- applying a barrier member to the shaped portion to shield the drinking aperture;
- wherein during said method the drinking aperture is not touched by human hands.
- Preferably, including the step of selecting the barrier from a supply of barriers.
- Preferably, including the step of applying a vacuum to the barrier to urge the barrier into contact with said shaped portion.
- Preferably, the step of applying the barrier to said shaped portion includes pressing the barrier against the shaped portion.
- Preferably, the step of forming the shaped portion includes thermoforming a portion of a sheet of material.
- Preferably, including the step of severing the shaped portion from the sheet of material.
- Preferably, further including the step of, after applying the barrier to a shaped portion, stacking a plurality of lids and shaped portions to form a transportable stack.
- Preferably, including the step of sealingly packaging said stack as a single unit.
-

FIGS. 5 b and 6 b show the barrier members of 5 a, 6 a, applied to a lid. - In the illustrated examples, shielded lids 1 (see
FIGS. 5 b, 6 b) are produced during a manufacturing process (seeFIGS. 1 a, 1 b to 4 a, 4 b) and prior to delivery to a café or the like. The manufacturing process in a preferred embodiment includes moving a sheet of material in the form ofstrip 2 along a production line 4 including throughproduction stations strip 2 is typically produced through an extrusion process and supplied to the first production station 6 in a hot, pliable, form. Thestrip 2 could be manufactured on site or brought from a third party. However, it should be understood thatstrip 2 could be produced using various typical sheet forming methods. At the first production station (not shown) thestrip 2 is thermoformed to create ashaped portion 12 within thestrip 2. This involves forming thepliable material 2 within a mould (not shown) to form thematerial 2 into alid shape 12 as shown in the Figures. In this example, the thermoforming is vacuum forming, that is, thestrip 2 is sucked onto a male die. In other examples of the process, thematerial 2 may be supplied in solid form, in a roll and heated to be made pliable before application or the like. Thelids 12 could also be made through injection moulding. - After thermoforming, the shaped portion 12 (i.e. lid) is moved to the second station 6 (see
FIGS. 1 a, 1 b). Station 6 is a punching station at which theshaped portion 12 is sandwiched between a punch tool 6 a and a complementary anvil 6 b to form adrinking aperture 12 a, vent holes and the like. From station 6 theshaped portion 12 is moved to the third station 8 (seeFIGS. 2 a 2 b). -
Third station 8 is a barrier application station at which abarrier 14 is applied to the formed portion 12 (seeFIGS. 2 a, 2 b).Station 8 includes asticker application tool 8 a. Thetool 8 a includes a main body 8 b referred to as a “mask” integrally formed with ashaft 8 c projecting therefrom. A collar 8 d embraces theshaft 8 c and carries vacuum fingers 8 e which slidingly project through apertures (not shown) through the mask 8 b in a direction parallel to theshaft 8 c. -
FIGS. 1 a, 1 b show thetool 8 a in its barrier selecting position in which the fingers 8 e project beyond the mask 8 b to suctionally engage the face of abarrier 14 to adispenser 8 f. - From the barrier selecting position of
FIGS. 1 a, 1 b thetool 8 a is moved to a sticker applying position ofFIGS. 2 a, 2 b. In this variant thetool 8 a rotates from a horizontal barrier selecting position to a vertical barrier applying position. The sticker could at this stage or later applied include advertising or the like. - In the position of
FIGS. 2 a, 2 b thetool 8 a is aligned with the shapedportion 12 sitting atstation 8. Thetool 8 a is then relatively advanced towards the shaped portion 12 (in this case lowered) to press thebarrier 14 onto the shapedportion 12. As thetool 8 a advances toward theportion 12, thebarrier 14, carried by the fingers 12 e, contacts the shaped portion 12 (seeFIGS. 3 a, 3 b). With continued advancement of thetool 8 a, the collar 8 d and fingers 8 e remain stationary whilst the main body 8 b continues on the production line 4. The main body 8 b has a face (not shown) shaped to complement the shapedportion 12 so as to conformably apply thebarrier 14 to the shapedportion 12. - From the position of
FIGS. 4 a, 4 b thetool 8 a is withdrawn (in this example raised) and returns to select a further barrier from thedispenser 8 f whilst thestrip 2 is incremented along the production line 4 to move the newly shielded shapedportion 12 to the station 10 (seeFIGS. 4 a, 4 b). - The
station 10 is a trimming station including acutter 10 a and anvil 10 b. The anvil 10 b has a central bore and is lowered into contact with thestrip 2 so as to encircle the shielded shapedportion 12. Thecutter 10 a has a circular cutting edge complementary to the bore of the anvil 10 b and is upwardly driven to make a circular cut severing the shielded shapedportion 12 from thestrip 2. Thus a shielded lid 1 is formed, although of course its formed plastic portion still fits the description of “a shaped portion” 12. Thesticker 14 however can be dressed before trimming or after trimming. - With continued advancement of the
tool 10 a the newly formedlid 12 is driven to engage the underside of an overlying previously formedlid 12. Thus the newly formed shieldedlid 12 is added to the stack oflids 12. In this example, the newly formed shieldedlid 12 nests within the upwardlyadjacent lid 12 as shown in the Figures. - The shapes of the described
exemplary lids 12 andbarriers 14 are better shown in more detail inFIGS. 5 a, 5 b and 6 a, 6 b. - As can be seen in for example
FIGS. 5 a, 5 b, 6 a, 6 b, the shapedportion 12, which is to become alid 12, includes an upwardly converging conical exterior 12 c surrounding a circular well orcentral portion 12 d dimensioned to receive the bottom of a cup (not shown). The well 12 d has an upwardly diverging conical side wall 12 b. The wall 12 c and the wall 12 b of the well 12 d are connected about the upper peripheries by a rim 12 e. Theaperture 12 a is spaced about the rim. There may be one or more apertures. The wall 12 c is surrounded by acircular flange 12 f shaped to engage the rim of a cup. - The
flange 12 f includes an outwardly bulbous portion (not shown) defining an annular recess (not shown) dimensioned to receive a more or less toroidal rim of a cup. The bulbous portion is shaped to embrace the rim of the cup and defines an annular nose which in use underlies the rim of the cup to hold thelid 12 in place as per a standard coffee cup lid. Below the nose is a short downwardly diverging conical skirt (not shown) which acts on the rim of the cup to provide a lead in when fitting thelid 12 to the cup. - When the
lids 12, or shaped portions which are to becomelids 12, are stacked an interior of the skirt rests on an exterior of the bulbous portion defining a circular line of contact and in turn defining the pitch at which thelids 12 are stacked. - The
barrier 14, in the example ofFIGS. 5 a and 6 a, is a sticker predominantly consisting of a thin pliable piece cut from a sheet of material. The sticker may be formed of paper treated with a suitable adhesive or any other suitable material. - The
sticker 14 in an embodiment is about twice as long as it is wide when viewed in plan. One end of the sticker terminates in a straight edge 14 a which runs transverse to the sticker's length. A central portion 14 b is positioned towards the other end of thesticker 14. The central portion 14 b can be of any shape and size. A straight bridging portion 14 c runs parallel to the sticker's length and connects a rectangular body of material defining the edge 14 a to the central portion 14 b. On either side of the bridging portion 14 c aportion 14 d projects from the body of material. Eachportion 14 d has an outer edge 14 g and aninclined edge 14 h. The inclined edges 14 h diverge from each other in a direction away from the edge 14 a and thus arespective opening 14 e is defined between eachportion 14 d and the bridging portion 14 c. A pull tab 14 f extends from the circular portion 14 b in a direction parallel to the length of thesticker 14. Thesticker 14 would be made of a single piece of material and could include separable slits, perforations, scores or the like. Thesticker 14 could be made of a biodegradable material. - In alternate embodiments the
stickers 14 may be applied by heat or by heat shrinking or vacuum shrinking. Heat and heat shrinking eliminates the need for cuts and perforations as it molds theplastic sticker 14 around the contours, however, slight scores may be required. It also eliminates the need to makestickers 14 in different shapes to suit different shape lids 12. Thestickers 14 may also be applied without heat and/or only with a downward pressure and use of an adhesive or the like. In this regard, the section about the aperture would utilise food grade adhesive or the like and leave no residue about the aperture. Thesticker 14 may cover the entire mouth area or thewhole lid 12. Thesticker 14 would be drawn using a vacuum, but there can be other ways to draw the stickers, like a roll over the lids that by pressing down, will apply thesticker 14 and release thesticker 14 from the roll, or a roller that rolls over thelids 12 and applies the sticker in a rolling motion. The tab 14 f is generally positioned towards the center of thelid 12 so the pulling motion is down, pulling the tab 14 f upwards may cause thelid 12 to pop off the cup. Thesticker 14 can be made using any thin material, whether plastic, vinyl, paper etc. Thesticker 14 will be adhered back onto the side of the cup to prevent littering. - In use, the edge 14 a follows the circular lower extent of the surface 12 c and the central portion 14 b is adhered to the floor of the well 12 d such that the bridging portion 14 c directly overlies the
drinking aperture 12 a and runs down the conical wall of the well 12 d. As the material defining the edge 14 a is deformed about the surface 12 c thesticker 14 is deformed to close theopenings 14 e and theinclined portions 14 d overlie the conical wall of the well 12 d. - The
central portion 14 d serves to shield the floor of well 12 d, which may contact the consumer's nose. It is also a convenient place for displaying images, advertising, trademarks, and/or other markings. By way of example the markings may be logos or advertisements. A business, such as a cafe or coffee supplier, might pay for their identity to be applied to the spot. - Of course some deformation of the
sticker 14 is required to follow the complex curvatures of the shapedportion 12. The inclusion of theopenings 14 e serves to minimize overlapping portions of material and/or potential folds in the material which may “scrunch up”. Thus thissticker 14 sits flat against the shapedportion 12 to permit efficient stacking. - No part of the
sticker 14 overlies theflange 12 f, such that when stacked the circular line of contact between the portion 12 g and an upwardlyadjacent lid 12 is not broken by thesticker 14. By spacing thesticker 14 from the point of contact, thelids 12 may be efficiently stacked to form a straight vertical stack 30 which is stable. Such stacking qualities are of course highly desirable to suit packaging and transport and easy handling by the barista or other café staff. In particular a stack 30 of shieldedlids 12 can be packaged in a tube of pliable plastic material (not shown) to shield them from contamination between the manufacturer and the barista or during use at a café. The barista may then receive the sealed package and simply remove the stack from the package and transfer it to a convenient location. By way of example, the stack 30 may be placed atop a coffee machine or the like, in which case the stability of the stack is highly desirable so that the stack does not fall over in response to machine vibration or the like. - The
sticker 14 in a preferred embodiment has strategically placed points of adhesive—in this case, one adjacent each end of the edge 14 a and one adjacent the pull tab 14 f. The degree of adhesion is selected to resist inadvertent removal of thesticker 14 from the shapedportion 12 whilst permitting removal ofindividual stickers 14 from thedispenser 8 f and removal of thesticker 14 by the consumer. Thesticker 14 preferably covers the hole oraperture 12 a and acts to stop liquid located within the cup from splattering through the hole when a consumer is walking or when pressing on the sides of the cup. Thesticker 14 can also be applied to the side of the cup once peeled from the lid to become a “cup print” or advertising as well as to prevent litter. - For the purpose of removal by the consumer, the pull tab 14 f is positioned to be grasped and pulled horizontally towards the edge 14 a and then, without releasing the pull tab 14 f, to be pulled downwardly to peel the material defining the edge 14 a from the conical surface 12 c. This positioning of the pull tab 14 c desirably allows for the removal of the
sticker 14 in substance without upward force being applied, such that the likelihood of inadvertently pulling thelid 12 from the cup is reduced. - Following the described example, a shielded
lid 12 is manufactured and supplied to the retailer (e.g. café or the like) in a fully assembled configuration. This ensures that a barista, café staff, delivery man or the like has not touched the drinking aperture prior to use by a consumer. This will be of great reassurance to many consumers and a significant advance in hygiene. - Various exemplary features have been described. These examples do not limit the scope of the invention as described herein. Many other examples are possible. By way of example, the ordering of the steps may be revised—the
lids 12 could be stacked atop to the shaped portion prior to it being severed from thesheet 2, or thesticker 14 may be applied after a shaped portion is severed from the sheet. Indeed, shaped portions may be formed other than from sheet material. - The orientation and scale of the production line may also be varied. Multiples of the described work stations may be arranged in parallel or series. In one example, an extruder horizontally feeds a sheet of hot pliable material to a drum having a horizontal axis about which it is rotatable, wherein the drum includes 7 rows of 8 vacuum forming dies along its length. The drum rotates continuously forming shaped portions as it carries the sheet material from about a 2 o'clock to about a 7 o'clock position. At about the 7 o'clock position the sheet peels away from the drum and moves downwardly through 7 parallel vertically-oriented variants of the production line 4.
- The lids 1 may be of various shapes and sizes, including different spout shapes, etc. Indeed the lids 1 may be spoutless.
- Although the invention has been described with reference to specific examples, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms.
