Definitions

  • This invention relates to two-piece disposable cups, suited for cold and warm beverages, peanuts, pop-corn and other solid foodstuffs, and especially to cups made of paper or paperboard.
  • Customary disposable cups usually comprise a bottom, a generally truncated conical body or liquid holding portion.
  • This type of cup will be referred to as a two-piece cup.
  • a separate lid can be applied over the opening of the cup.
  • This type of cup will be referred to as a three-piece cup, since it has a body portion and a separate lid, as opposed to the cup according to the invention, which has a body portion with an integrated lid.
  • Most standard cup designs thus use a separate replaceable lid to render the cup spill proof or spill resistant.
  • Attempts have been made to incorporate a folding lid in a two-piece design, however, such designs have a number of functional problems. These, and other designs, use built in straws or side spout mechanisms or have a closure apparatus that requires a complex folding mechanisms, rendering them expensive and/or difficult to manufacture, difficult for consumers to use and/or difficult to stack.
  • a problem with two-piece cups is that they possess a wide open top, which is subject to spillage especially if used during sporting events, such as running events, or in any situation where there is an activity or where significant movement of the cup occurs.
  • the problem has been overcome in the marketplace by the use of the three-piece cups, which involves placement of a detachable lid secured to the top of the cup,
  • the three-piece design suffers from a variety of problems such as the inconvenience and time required to secure the lid to the cup, storage and transport, disposal problems if the lid were to blow off, and inconvenience in terms of controlling the flow of liquid because your nose hits the lid of the cup and potential spillage when liquids splash out of the opening.
  • Two-piece disposable cups with integral lids and comprising the features in the preamble of claim 1 are shown in, for example, US-A-5,960,987 (Solland et al.) US-A-4,620,665 (McSherry) and GB-A-2 269 811 (Weston). Both of these designs have a deep ovate semicircular shaped lid portion of the die-cut cup, making the lid come to a rest position/sealing position in a semi-upright position along the opening edge of the cup, leaving the cup body portion cross-section substantially circular. Some type of locking mechanism on the upper edge of the cup is employed to hold the lid to the top edge of the cup opening.
  • a one-piece disposable cup according to the invention makes use of a lid which is formed from a semi-circular die-cut piece adjoined to the body portion of the cup.
  • the general shape of the lid is circular, or slightly oval or shallow semi-circular.
  • the lines of the scribe line arc forming the first fold line for the lid, adjacent the opening edge of the cup, are slightly flattened.
  • the arc of the die-cut cup according to the invention is shallower than the corresponding arc of the known art.
  • the ratio of a horizontal line, which joins the ends of the upper portion of the first fold line where it meets the edge of the cup, to the vertical distance from the center of the horizontal line to the lowest point of the arc of the first fold line, is approximately 4 for the cup, whilst the same ratio for the known art is between 1.5 and 2.5.
  • the cup according to the invention has two unique second fold lines along the upper edge of the arc which forms the lid.
  • Each second fold line joins the first fold line near the upper edge of the first fold line and connects to the opening edge of the cup to form a triangular shape enclosed by the second fold line, the part of the primary fold line which runs from a first end of the second fold line to the edge of the cup, and the part of the edge of the lid which runs from the edge of the cup to a second end of the second fold line.
  • the cup lid closing mechanism functions in the following fashion: by a user exerting a slight pressure on the side of the lid, when the lid is in a vertical position, will cause the lid to change shape from convex (open and vertical) to concave shape, with a sudden click or flip towards the cup opening, causing the lid to fold over into the mouth of the body portion of the cup.
  • the lid itself will move to a new stable position located inside the mouth, sealing the contents of the cup from splashing out from the cup.
  • the lid's final closed position is near to the horizontal, within the body portion of the cup. This near horizontal closed position is caused by the shallower nature of the arc of the first fold line and the presence of the second fold lines.
  • a double click from each of the two second fold lines
  • the outer circumference of the lid of the cup is designed to be larger than the inner circumference of the body portion of the cup in the area of the intended closed position of the lid.
  • This action may be performed by pushing on the lid itself, or by gently squeezing the sides of the cup together by applying pressure to the sides adjacent the two second fold lines. A combination of both actions is also possible.
  • the final resting position is determined by the angle of the second fold lines relative the angle of the arc of the first fold line near the second fold lines. Near the resting location for the lid in the body portion of the cup there is a resistance to further movement of the lid into the cup.
  • the resistance is caused by the pressure exerted by the increasingly smaller opening of the cup body on the lid, and by the resistance afforded by the presence of the second fold lines.
  • the friction between the lid edge and the inside of the body of the cup renders the cup spill resistant and helps to secure the lid in its closed position within the body of the cup.
  • the shape of the lid, in the closed position is thus deformed into a parabolic shape within the body of the cup. This renders further rigidity to the lid and the cup as a whole.
  • the described function of the lid inside the body of the cup is the primary locking mechanism for the lid, in its closed position.
  • the locking of the lid in its closed position is preferably further enhanced by the precise shaping of the lid, so as to exaggerate the parabolic shape of the lid, when the lid is pushed into the body of the cup, and by the shape of the first fold lines, which causes the parabolic shaping of the lid when the lid is pushed to the closed position.
  • the second fold lines function as a second locking mechanism, to hold or secure the lid in its closed position within the body of the cup.
  • the lid thus attains a closed position within the cup, with a general plane of the lid near a horizontal plane, or with the movable edge of the lid slightly lower than the opposite folding edge of the lid.
  • the opposing forces between the lid edge and the inside surface of the body of the cup renders enough friction to securely hold the lid within the body and render the cup spill resistant.
  • the lid when the lid is in its closed position, there occurs a distortion of the body of the cup, from an oval shape, having a substantially flattened part where the lid attaches to the body portion, to a an ovate shape in the perpendicular direction (as seen from the top or bottom of the cup).
  • This shaping in the closed position of the lid is due to the shape of the lid in the closed position.
  • This feature renders the cup body significantly stronger compared to when the lid is not in the closed position.
  • the ovate shape of the body when the lid is in the closed position, makes the cup very easy to hold and also leads the cup user to more easily find the opening of the cup lid.
  • the cup body when the lid is in the closed position, the cup body retains a substantially circular cross-section shape, without the benefits described above of the ovate body shape of the cup according to the invention.
  • the opening arranged along the edge of the lid can be shaped in any suitable way to control the flow of liquid from the cup.
  • the opening can further be shaped to accommodate straws and/or direct drinking from the cup body edge adjacent the opening, depending upon the application.
  • the opening and the raised or protruding edge of the body portion of the cup when the lid is in the closed position, combine to form a natural drinking edge or "funnel". Due to the interaction of the opening/lid and the body portion of the cup, the user of the cup can procure liquid without hitting his/her nose against the lid or the body of the cup, contributing to a more pleasant drinking experience. It is thus not necessary to lean the head backwards to drink the last drops from the cup according to the invention, merely tilting the cup further suffices.
  • the only escape route for liquid is through the opening of the lid.
  • the raised/upwardly protruding edges of the drinking lip also contributes to preventing spillage.
  • the primary locking mechanism of the lid in the closed position is, as described, the friction between the lid and the inside surface of the body of the cup, and the secondary locking mechanism being provided by the second fold lines of the lid.
  • a series of preferable tertiary locking mechanisms can be employed to further secure the lid within the cup opening.
  • the tertiary locking mechanisms may comprise locking edges within the side of the body of the cup, which edge catches the edge of the lid, when the lid is in the closed position.
  • the locking edges are preferably arranged adjacent the second fold lines of the lid, to catch the part of the edge of the lid adjacent the second fold lines.
  • the locking edges are formed to catch the edge portions of the lid adjacent the opening of the lid, or a combination of both arrangements of the locking edges.
  • a glued-in locking edge might be used, instead or in combination with, locking edges formed directly in the body of the cup.
  • a further possibility is to utilize one or more protuberances sticking out from the edge of the lid, which protuberances are insertable into slits arranged on the body portion of the cup, to lock the lid in the closed position.
  • Still a further possibility of forming a locking edge is to utilize at least one substantially horizontal slit in the body portion, whereby the portion of the body located above the slit or slits would be pushed inwards to create a locking edge for catching the edge of the lid, when the lid is in the closed position.
  • the cup body joint line i.e. the substantially vertical edge along which the cup is joined together, can be placed directly adjacent a triangle formed by one of the second fold lines etc. (as described above).
  • This location of the joint line (on the side of the cup), allows the unencumbered placement of lettering on the front of the cup, the back of the cup and on the lid, without having to compensate or align graphics or text for the glueing of the joint line (or any other joining technique used).
  • the cup has flip top lid which when pushed into position makes the cup spill resistant.
  • This cup is intended to be used as a general purpose sport's cup suitable for many activities such as running events (i.e., marathons, triathlons, 10 km races etc.).
  • the cup also has a general purpose market as a children's cup, airline cup, medicine cup or in any situation where a spill resistant cup is required.
  • the cup can be adapted to the fast food market and replace standard three-piece cup designs.
  • the cup size and opening for fluids can be of various sizes or fitted with a straw for use in many applications. Additional uses are foreseen in the food industry in any application which requires spillage prevention, for example as a popcorn or peanut container, french fries container, etc.
  • the opening in the lid would then be optimized to let a desired amount of contained matter out when pouring.
  • the present invention incorporates the use of a die-cut method which has been used on some paper products containers mainly for fast foods (i.e.,popcorn or chips).
  • the die-cut mechanism for these products allows a portion of the carton to fold over to partially cover the contents to either keep in heat or protect the contents while it is sitting.
  • the difficulty with this mechanism is that the lid is unstable and liquids cannot be placed in such containers because they are not leak proof.
  • the present invention uses a simple die-cut mechanism and applies it directly to the beverage cup market.
  • the invention utilizes a two-piece cup design that eliminates the need for a separate lid thus eliminating the need for additional storage and disposal.
  • This type of cup will be referred to as a two-piece cup, since it has a body portion and an integrated lid.
  • the cup according to the invention is easy to use.
  • the invention uses a simple die-cut and quick fold mechanism.
  • the lid is so designed that a reasonably secure and spill resistant cover results when the lid is pushed into a closed position in the cup opening. Securing the lid requires a simple push and does not require any significant manipulation.
  • the cup according to the invention is stackable after assembly into cup shape, and the unique "flip” or “click” which occurs when the lid is slightly pushed, allows the lid to flip into a semi-closed or closed position making total closure of the lid a simple operation.
  • the lid edge is moved fully into the mouth opening it clicks into position being held there by the nature of the deformation and by the lower edge of the mouthpiece member.
  • the lid of the cup is so shaped that it sits tightly against the sides of the cup.
  • the deformation of the lid and the sides of the cup helps secure the lid in the cup opening.
  • the deformation thus formed also changes the cup profile to a more ovate shape which makes it more rigid and thus easier to hold or grasp.
  • the lid to be is also deformed along the sides making it more rigid.
  • the mouthpiece for the cup forms a natural hollow between the lid and the edge of the cup which has been angled up. This allows the user a quick point of reference to find the opening, and it allows the liquid to pool temporarily in the space formed by the lid and sidewalls of the cup thus minimizing spillage or splashing when the cup is moved about.
  • the construction also forms a convenient mouthpiece for the user.
  • the hollow between the edge of the cup allows the user to angle the cup and drink without hitting their nose into the cup lid.
  • the mouthpiece is used as a convenient pouring snout or funnel.
  • Fig. 12 shows all the applicable components of the cup in a fold out position as it would be cut from a paperboard or similar material sheet.
  • the cup 1 according to the invention has two parts, a cup body portion 2 with a lid 4 and a mouthpiece/lid securing member 9 , and a bottom 10 of the cup.
  • the body portion further has a first edge 12 , a second edge 13 , a top edge 3 and a bottom edge 11 .
  • the lid 4 has a free edge 5 , which is curved and having a cross-sectional dimension which is larger than the diameter of the cup in the area where the lid is cooperating with the cup to form a seal (which will be described later), after the cup has been assembled.
  • the free edge has end portions 14 where the free edge meets the body portion of the cup 2 .
  • the lid further has an opening formed along the free edge 5 , to allow liquid to pass out from the cup, when the lid is in a closed position.
  • a first curved score line 7 completes the shape of the lid 4 , together with the free edge 5 of the lid. The lid is thus foldable along the first score line, relative the cup body portion 2 .
  • Two second score lines 8 are arranged adjacent the end portions 14 of the free edge 5 of the lid 4 . The second score lines allow the lid to click towards the opening of the cup, formed by the top edge 3 of the cup body portion 2 , when a cup user pushes the lid from the raised position towards the cup opening.
  • the parts are assembled to form the completed product, a two-piece cup according to the invention.
  • the first edge 12 and the second edge 13 of the cup body portion 2 are brought together and glued to form a truncated conical shaped cup.
  • the bottom 10 of the cup is placed within the cup body, adjacent a lower edge 11 of the body portion, and fastened into position, for example by glueing.
  • Figs. 1, 4, 5 and 9 show the cup 1 according to the invention in the assembled form, with the lid 4 in a raised position.
  • the lid When a user of the cup pushes the lid 4 from the raised position towards the opening of the cup, as shown in Figs. 2 and 6, the lid changes shape from convex (open and vertical) to concave shape, with a sudden click or flip towards the cup opening, causing the lid to fold over into the mouthpiece 9 of the body portion 2 of the cup 1 .
  • the lid itself will move to a new stable position located inside the mouthpiece, sealing the contents of the cup from exiting out from the cup.
  • the lid's final closed position is preferably near to the horizontal, within the body portion of the cup. This near horizontal closed position is caused by the shallower nature of the arc of the first fold line and the presence of the second fold lines.
  • the arrangement of the second fold lines are altered to allow the lid to close in a position more upright compared to the horizontal position.
  • This feature is used mainly with solid cup contents.
  • a double click (from each of the two second fold lines) occurs, allowing a more definitive and significant movement, flip or click of the lid to the closed position within the body portion of the cup.
  • the user may push the lid slightly towards the bottom 10 of the cup 1 , as shown in Fig. 3, to reach the final resting/closed position of the lid in the cup body, as shown in Fig. 3A.
  • the lid is rendered foldable by the approximately semicircular first score line 7 , which is arranged, for example by a die-cut operation, on the side of the cup that occupies approximately one third of the circumference of the cup face.
  • first score line 7 When the lid is pushed towards the mouthpiece 9 of the cup, the nature of the first score line 7 , in conjunction with the action of the second score lines 8 , and deformation of the cup wall created by the attached lid (Fig. 7) causes the lid to click or flip into a semi-closed or closed position. The process in mathematics is called a catastrophe event. From the semi-closed position the lid can then be pushed slightly further into the mouth of the cup, to a determined position marked by the bottom edge of the mouthpiece, as shown in Fig. 3A. The final position of the bottom edge of the mouthpiece in the mouth of the cup, is determined by the arrangement/location of the second score lines 8 .
  • the lid 4 When the lid 4 is pushed further into the opening of the cup 1 , the lid forms a tight fit to the sidewalls of the cup, as shown in Figs. 3A, 8, 10 and 11.
  • the inclusion of a mouthpiece 9 marks the line to which the cup lid is pushed.
  • the lid clicks into position and is secured and is prevented from moving back by friction forces between the lid and the cup body portion, as described earlier.
  • the lid is shaped so that, as it is pushed down into the cup, it becomes more constricted and pushes against the side of the cup. As the lid presses against the walls of the cup the consequent pressure causes a deformation of the cup from a circular to a ovate shape.
  • the shape of the lid also deforms to form a parabolic or semicircular shape caused by the shape of the die-cut and the consequent pressure on the sidewalls of the cup within the opening of the cup mouth.
  • the nature of the deformations renders the lid into a stronger structural shape and secures the lid to the inside of the cup.
  • the shape of the lid is somewhat circular and slightly larger than the cup dimension at the intended closing position for the lid, and is shaped to deform the cup body into a unique ovate shape.
  • one or more protuberances 15 may be arranged along the free edge 5 of the lid, to be insertable into correspondingly arranged slits 16 in the cup body, when the lid is in the closed position, see Figs. 4A, 5A and 7A.
  • a crescent-shaped slit 17 may be arranged in the cup body at a position corresponding to the lid 4 closed position, see Figs. 4B and 7B.
  • the area of the cup body located immediately above the crescent slit is pushed in slightly, towards the inside of the cup, to create an edge which holds the lid in the closed position, but which allows the lid to be pressed past the crescent slit into the closed position.
  • a further alternative is shown in Figs. 4D, 4E and 7C.
  • a glued-in member 20 is arranged inside the cup body adjacent the mouthpiece 9 , and is arranged so that a lower edge of the member forms an edge which holds the lid in the closed position, but which allows the lid to be pressed past the member into the closed position.
  • One or more dimples 21 are arranged to protrude inwards into the cup at locations adjacent the position of the lid in the closed position. The one or more dimples thus creates, which hold the lid in the closed position, but which allows the lid to be pressed past the dimples into the closed position.
  • the angle of the cup face adjacent the opening in the lid is raised and forms a mouthpiece 9 for convenient consumption of the contents of the cup.
  • the deformation of the cup causes an increase in rigidity of the cup body rendering it easier to hold.
  • a semicircular cut 6 is made in the lid so that it forms a pathway or opening for liquid, or any other cup content, when the lid is secured within the open face of the cup.
  • the hole can be sized to various dimensions to control the flow of liquid or to hold a straw.
  • the opening may be in the shape of several slits allowing liquid to pass, but not ice cubes or other larger objects like orange slices etc.
  • a disposable cup comprises a bottom insert, and a body portion having an integral foldable lid portion.
  • the foldable lid portion is joined to the body portion along an arcuate folding line, so that, when the lid portion is pushed towards the mouthpiece portion, the lid portion flips into a position inside the mouthpiece.
  • the foldable lid portion has a larger cross-dimension than the cross-dimension of the body portion, at the intended closed position of the lid, so that, when the lid portion is pushed further past the mouthpiece portion into the body portion, the lid portion is bent further into a convex shape to seal liquid access along the inside of the mouthpiece portion and is secured inside the body portion by the action of the second score lines.
  • the dimensions of the cup are relative.
  • the cup sizes can vary depending upon the application for the product.
  • the shape or size of the lid may be altered to suit both the type of product contained in the cup and to the desired reliability of the seal between the lid and the inside body of the cup.
  • the closure of the lid i.e. the movement of the lid from the raised position to the closed position, will occur as one single event. No further push would be required to bring the lid into the closed position, as the frictional forces between the edge of the lid and the inside of the cup would be reduced.
  • This particular embodiment of the invention would be used in instances where a tight frictional fit and consequent spillage would not be a factor, for instance when the cup is used to hold larger solids like peanuts.
  • the cup may be formed, whether by using custom-designed machinery, or by adapting existing machinery.
  • the cup is constructed by cutting a blank shaped to provide the shape described above.
  • the blank is provided with the curved score line beneath the lid portion, extending from the first intersection of the lid portion with the upper edge, curving downwardly therefrom, and thence back upwardly to the second intersection of the lid portion with the upper edge, such that the lid portion is foldable along the curved score line towards an opposite side of the upper edge when the cup is assembled.
  • the blank is also provided with its generally axial score lines spaced slightly from the intersections and extending from the curved score line to an upper edge of the lid portion, thereby defining, with the upper edge and the curved score line, small generally triangular portions.
  • the blank is then formed into a cup by joining opposing lateral side edges and securing a bottom to the blank.
  • the scoring is accomplished at the same time or as part of the same operation as when cutting the blank, but with proper alignment of the web from which the blanks are cut, it is conceivable that the scoring could be provided before the blank is cut. Similarly, although unlikely, it is possible that the scoring could be provided in a separate operation after the blank is cut.
  • This invention relates to two-piece disposable cups, having a lid, which is movable between a raised position and a closed position, possibly via a semi-closed position.
