Description

The present invention relates to a lid for a beverage cup.

In recent years, many beverages that are offered at cafes, convenience stores, etc., or purchased for take-out are put in disposable cups. Plastic lids are typically used on such cups to prevent beverages from spilling out of the cup during portability. Further, if the content is a warm beverage, such a lid can prevent the beverage from suddenly cooling.

As shown in FIG. 10, the lid 900 of the beverage cup shown in Patent Document 1 has a tab 901 for opening and closing the drinking spout, a protrusion 902 provided on the upper surface of the tab 901, and above the tab 901 in a plan view. It is provided with a recess 903 provided. When the cup is not in use, the tab 901 closes the spout of the lid 900. On the other hand, when the user tries to drink a beverage from the cup, the protrusion 902 is pushed into the recess 903 to be hooked. As a result, the mouthpiece is opened for use.

Design Registration No. 1637653

Since the lid of the conventional beverage cup has a relatively small mouth, it is not possible to enjoy the scent of the beverage. For example, when drinking coffee, there is a demand to enjoy the aroma of coffee in addition to the deliciousness of coffee itself. In the case of a cup without a lid, for example, a mug, the scent of coffee spreads from the top of the mug, so when the user brings the mug close to the mouth to drink coffee, the scent of coffee reaches the user's nose and enjoys this. it can.

However, if the beverage cup is covered, the scent is trapped in the lid and cannot be felt. In particular, in the lid of the beverage cup described above, the opening area of the drinking spout is reduced in order to prevent inadvertent liquid leakage. As a result, there is a problem that the amount of fragrance leaking from the mouth is reduced. However, widening the spout increases the risk of inadvertent leaks. As described above, enjoying the scent of a beverage and preventing liquid leakage have contradictory characteristics, and therefore, there has been no conventional product that satisfies both requirements.

The present invention has been made in view of such problems in the past, and one of the purposes thereof is to enjoy the scent of the beverage in the cup while maintaining the structure in which the beverage does not easily leak from the cup. The purpose is to provide a lid for a beverage cup.

As the beverage cup 200, one made of paper or plastic having a bottomed tubular shape is used. In the example of FIG. 1, a beverage cup 200 having a cylindrical appearance was used, but a beverage cup having an arbitrary shape such as a square columnar shape or a polygonal columnar shape can be used, and the beverage cup lid has a shape of the beverage cup. Designed accordingly.
(Beverage cup lid 100)

The beverage cup lid 100 is used as the lid of the beverage cup 200. As shown in FIG. 1, the beverage cup lid 100 is composed of a lid body 10 and an edge portion 20 formed around the lid body 10. The lid body 10 is formed in a size and shape capable of closing the open end 210 of the beverage cup 200. Further, the edge portion 20 has a groove portion 21 opened downward as shown in the end views of FIGS. 8A to 8C in an annular shape, and the opening end 210 of the beverage cup 200 is fitted and held in a holding state. Can be done. Further, by forming the lid body 10 in a stepped shape so as to be higher than the edge portion 20, the drinking mouth (opening 30 described later) formed in the lid body 10 can be projected from the edge portion 20 to make it easier to drink. ..

The lid body 10 and the edge 20 are integrally molded of a resin material such as plastic. It may also be a biodegradable plastic. Alternatively, it may be made of paper or talc.

The beverage cup lid 100 is preferably non-transparent. If the content is a warm beverage, the heat retention can be enhanced. However, the lid for a beverage cup of the present invention is not limited to non-transparent. By making it transparent, it becomes easy to check the contents of the beverage cup. As described above, the transparency, the coloring of the beverage cup, the material, and the like can be appropriately selected depending on the contents and the purpose of use.

As shown in the perspective view of FIG. 2, the lid main body 10 has a peripheral edge portion 11, a lid main body recess 12, and a bottom surface 13 formed inside the edge portion 20. Further, the bottom surface 13 is formed with a second fitting recess 80 recessed from this, and the second fitting recess 80 is further formed with a first fitting recess 60 recessed from this.

The peripheral edge portion 11 is projected upward so as to be higher than the edge portion 20. Further, the lid main body recess 12 is recessed from the peripheral edge portion 11. The second fitting recess 80 has a flat shape further recessed from the bottom surface 13 of the lid body recess 12.

On the other hand, an opening 30 is formed in a part of the lid main body 10. The opening 30 is provided eccentrically in the plan view of the lid body 10. In the example shown in the plan view of FIGS. 6 and 7, the peripheral portion 11 is formed on a part (lower side in the drawing). The opening 30 is covered with a cover 40.

Further, a first fitting recess 60 is formed on the bottom surface 81 of the second fitting recess 80. Further, a scent window 90 is formed on the bottom surface 61 of the first fitting recess 60. The scent window 90 is opened in the center of the lid body 10 adjacent to the opening 30. Further, the scent window 90 is closed by the push-in piece 70.
(Opening 30)

As shown in FIGS. 4 and 7, an opening 30 serving as a drinking spout is formed in a part of the peripheral edge portion 11 of the lid main body 10. The opening 30 is formed in a substantially rectangular shape. In the example of FIG. 7, the shape is an inverted isosceles trapezezoid, and the base is slightly curved along the peripheral edge portion 11. However, the shape of the opening 30 is not limited to this, and any shape such as a polygonal shape or an elliptical shape can be adopted.

The opening 30 is formed by partially cutting the peripheral edge portion 11 from one end of the bottom surface 13 of the lid main body recess 12 toward the outer peripheral edge 11a of the peripheral edge portion 11. Further, the opening 30 is provided on substantially the same plane as the bottom surface 13 of the lid main body recess 12. That is, the opening 30 is formed at a position one step lower than the upper surface of the adjacent peripheral edge portion 11 and the outer peripheral edge portion 11a of the peripheral edge portion 11. The opening 30, the peripheral edge 11 surrounding the opening 30, and the outer peripheral edge 11a serve as a drinking port for the cup lid. Such a shape makes it easier for the user to put a mouth on the lid body 10 and makes it easier to drink a beverage. Further, since the outer peripheral edge 11a is formed so as to stand upright from the outer peripheral end of the opening 30, when the user drinks a drink, the outer peripheral edge 11a is interposed between the opening 30 and the lips to drink the drink. Can be smoothly carried to the mouth. However, the lid body of the present invention is not limited to such a shape. For example, the top surface of the lid body may be flat without providing a recess.

The opening 30 can be closed by the opening / closing cover 40. That is, the cover portion 40 can be switched between a closed position for closing the opening 30 shown in FIGS. 2, 3 and 6 and an open position for opening the opening 30 shown in FIGS. 4, 5 and 7. it can. As a result, for example, when carrying the lidded beverage cup 1000, the cover portion 40 is set to the closed position to prevent the beverage held by the lidded beverage cup 1000 from leaking from the opening 30, and when drinking the beverage. As shown in the perspective view of FIG. 9, by switching the cover portion 40 to the open position, it is possible to put a mouth on the opening 30 and drink the beverage inside the cup 200. In this way, since the opening 30 of the beverage cup 1000 with a lid can be maintained in a closed state, there is little possibility that the beverage inside will pop out from the opening 30 when it is carried. On the other hand, when drinking a beverage, the opening 30 can be set as the open position and the beverage can be conveniently used.
(Cover 40)

The cover portion 40 is preferably formed integrally with the lid body 10. The cover portion 40 of FIG. 2 has a cover portion side hinge structure 41 that moves the cover portion 40 from the open position to the closed position between the cover portion 40 and the first fitting recess 60 and the second fitting recess 80. I have. Then, as shown in FIG. 6, by forming the first cutting line 50 on the lid main body 10 while leaving the cover portion side hinge structure 41, the cover portion 40 can be opened and closed by the cover portion side hinge structure 41 so that the opening 30 can be opened and closed. Can be provided in. The first cutting line may be cut in advance, or may be a half cut or a cutting line.
(Lift-up convex portion 42)

A lift-up convex portion 42 is provided on the upper surface 43 of the cover portion, which is the upper surface of the cover portion 40. The lift-up convex portion 42 is a block body having a rectangular shape in a plan view in a posture in which the cover portion 40 is in the closed position. Further, it protrudes in the direction perpendicular to the lid 100 for the beverage cup. As described above, since the lift-up convex portion 42 has a large portion to be pushed into the first fitting recess 60, which will be described later, it becomes easier to push into the first fitting recess 60. Further, the pushed portion can be stably held in the first fitting recess 60.
(First fitting recess 60 and second fitting recess 80)

Further, the lid body 10 according to the present embodiment is provided with a locking mechanism for holding the cover portion 40 in the open position. Specifically, as shown in FIGS. 2 and 3, a second fitting recess 80 is provided on the bottom surface 13 of the lid body recess 12, and a first fitting recess 60 is provided on the bottom surface 81 of the second fitting recess 80. Each is formed. Further, a scent window 90 is formed on the bottom surface 61 of the first fitting recess 60, and a push piece 70 for opening and closing the scent window 90 is provided so as to cover the scent window 90.

As shown in the plan view of FIG. 6, the second fitting recess 80 has a trapezoidal shape slightly tapered from the opening 30 toward the center of the beverage cup lid 100. The bottom surface 81 of the second fitting recess 80 is substantially parallel to the top surface of the peripheral edge 11 of the lid body 10.

The first fitting recess 60 is formed so that the receiving portion 62 into which the lift-up convex portion 42 is pushed and the scent window opening portion 63 in which the scent window 90 is opened to the outside are continuous. Then, the cover portion 40 can be held in the open position by press-fitting the lift-up convex portion 42 into the receiving portion 62. Therefore, the receiving portion 62 has a shape that follows the outer shape of the lift-up convex portion 42. This makes it easier to push the lift-up convex portion 42 into the first fitting recess 60. Further, the lift-up convex portion 42 is formed to be slightly larger than the receiving portion 62 so that the lift-up convex portion 42 can be easily held inside the receiving portion 62. Further, as described above, the lid body 10 including these members is molded of an elastically deformable resin material such as plastic. Therefore, the shape of the lift-up convex portion 42 is also deformed with the operation of pushing the lift-up convex portion 42 into the receiving portion 62 or pulling it out from the receiving portion 62, and such an operation can be repeated. As a result, the opening 30 can also be repeatedly opened and closed.

On the other hand, the scent window opening portion 63 is formed wider than the receiving portion 62. Further, the bottom surface 61 of the first fitting recess 60 is inclined upward from the opening 30 side toward the center of the beverage cup lid 100.
(Scent window 90)

Further, a scent window 90 is formed on the bottom surface 61 of the first fitting recess 60. Further, the push piece 70 is provided so as to open and close the scent window 90. The shape of the scent window 90 is not particularly limited as long as the scent of the beverage can be emitted to the outside from the scent window. In the present embodiment, it is formed substantially along the outer shape of the first fitting recess 60. The scent window 90 can be closed by an openable and closable push piece 70.
(Pushing piece 70)

The push piece 70 is preferably formed integrally with the lid body 10. For example, as shown in FIG. 6, the push-in piece 70 is opened and closed by the push-in one-side hinge structure 71 by forming the second cutting line 64 on the bottom surface 61 of the first fitting recess 60, leaving the push-in one-side hinge structure 71. It can be freely provided in the scent window 90. The second cutting line may also be cut in advance, or may be a half cut or a cutting line. The position of the push-in one-side hinge structure 71 is not particularly limited, but in the present embodiment, the cover portion-side hinge structure 41 and the push-in one-side hinge structure 71 are arranged in opposite postures.
(Hinge structure 71 on one side of push-in)

Further, a convex portion 72 on the pushing piece side is provided on the upper surface of the pushing piece 70. The shape of the push-in one-side convex portion 72 is not particularly limited as long as it can come into contact with the lift-up convex portion 42 described later. By providing the push-in piece side convex portion 72, the push-in piece 70 can be easily pushed into the scent window 90.
(Movement of the cover portion 40 from the closed position to the open position)

Next, the movement of the cover portion 40 from the closed position to the open position will be described. The cover portion 40 of FIGS. 2 and 3 is in a closed position for closing the opening 30. The lift-up convex portion 42 projects vertically on the upper surface 43 of the cover portion with respect to the beverage cup lid 100. Then, when the user tilts the lift-up convex portion 42 toward the first fitting recess 60 and the second fitting recess 80 with a finger, the lift-up convex portion 42 moves in the direction of the arrows in FIGS. 2 and 3. Then, it is pushed into the receiving portion 62 of the first fitting recess 60. By such an operation, the cover portion 40 can be moved to the open position.

4 and 5 show a state in which the cover portion 40 is tilted to open the opening 30. In this state, the lift-up convex portion 42 is held in the receiving portion 62 of the first fitting recess 60. The push-in piece 70 is inside the scent window 90 by the lift-up convex portion 42, and is pushed downward as shown by the arrows in FIGS. 4 and 5. As a result, in the scent window opening portion 63 of the first fitting recess 60, a part of the scent window 90 can be opened to the outside. At this time, the upper surface 43 of the cover portion comes into contact with the bottom surface 81 of the second fitting recess 80 and is held in the second fitting recess 80. As a result, the cover portion 40 is less likely to lift up, and the lift-up convex portion 42 can be stably held in the receiving portion 62.
(Opening and closing of the scent window 90)

Here, the opening and closing of the scent window 90 will be described more specifically with reference to the end views of FIGS. 8A to 8C. In FIG. 8A, the cover portion 40 is in the closed position, and the scent window 90 is also closed by the push piece 70. Then, when the lift-up convex portion 42 is pushed into the first fitting recess 60 as shown in FIG. 8B, the tip portion of the lift-up convex portion 42 comes into contact with the push-in one-side convex portion 72. Further, by pushing the lift-up convex portion 42, as shown in FIG. 8C, the lift-up convex portion 42 slides on the upper surface of the push-in one-side convex portion 72 and is pushed in, so that the push-up piece connected to the push-in one-side convex portion 72 As a result of the 70 being pushed down, the push piece 70 moves inside the scent window 90, that is, downward as indicated by the arrow, and a part of the scent window 90 is opened. As a result, the scent of the beverage leaks through the scent window 90, so that the user can enjoy the scent when drinking. In particular, the conventional cup has only a small area of the mouth open and the scent can hardly be enjoyed. In contrast, the beverage cup 1000 with a lid according to the present embodiment is provided with a scent window for enjoying the scent. As a result, an environment is realized in which the scent can be sufficiently supplied from the scent window and the beverage can be drunk while enjoying more scent while avoiding the occurrence of unintended liquid leakage from the mouthpiece.

Further, as described above, since the bottom surface 61 of the first fitting recess 60 is provided with an upward slope, the push piece 70 is also inclined with an upward slope. Further, since the pushing piece side convex portion 72 is provided on the upper surface of the pushing piece 70 having an upward slope, the lift-up convex portion 42 easily comes into contact with the pushing piece side convex portion 72, and the pushing piece 70 is placed inside the scent window 90. Can be easily pushed in.

The push-in one-side convex portion 72 is not particularly limited as long as it is provided at a position and shape that easily abuts on the lift-up convex portion 42. In the present embodiment, the shape is substantially rectangular in a plan view, and the shape is slightly tapered toward the tip side. Further, the degree of pushing the push piece 70 into the scent window 90 can be adjusted by the shape of the push piece side convex portion 72. As a result, the degree to which the scent window 90 is opened can be adjusted. For example, when the height of the convex portion 72 on one side of the push-in piece is increased, the push-in piece 70 is greatly pushed into the scent window 90, and the scent window 90 is greatly opened. On the other hand, when the height of the convex portion 72 on one side of the push-in piece is lowered, the push-in piece 70 is not excessively pushed into the inside of the scent window 90, and the degree to which the scent window 90 is opened becomes small.

The degree to which the scent window 90 is opened is not particularly limited. In the present embodiment, as shown in FIG. 8C, the push-in piece 70 is set so that the angle θ of moving downward from the position where the scent window 90 is closed is 30 ° or less, and the scent window 90 is partially opened. .. This is because if θ becomes too large, the scent window 90 is opened widely, and the possibility that the beverage in the cup spills from the scent window 90 increases.

In the present embodiment, the push-in piece side convex portion 72 is provided on the upper surface of the push-in piece 70, but the present invention is not limited to such an embodiment. For example, a protrusion may be further provided on the upper surface of the lift-up protrusion, and the push piece may be pushed into the scent window by the protrusion.

Further, as described above, the receiving portion 62 of the first fitting recess 60 has a shape that follows the outer shape of the lift-up convex portion 42. On the other hand, the scent window opening portion 63 is formed wider than the receiving portion 62. As shown in FIG. 8C, when the lift-up convex portion 42 is pushed into the receiving portion 62, the entire pushing piece 70 is pushed into the scent window 90, so that the scent window 90 is opened along the outer peripheral edge of the pushing piece 70. The window.

Here, as shown in FIG. 7, since the cover portion 40 is locked by the receiving portion 62, the portion of the scent window 90 included in the receiving portion 62 is covered with the cover portion 40 and is not opened to the outside. On the other hand, the scent window opening portion 63 is formed wider than the receiving portion 62 so as not to be covered by the cover portion 40. Therefore, only the scent window 90 included in the scent window opening portion 63 is partially opened to the outside. By adopting such a shape in the first fitting recess 60, it is possible to enjoy the scent from the scent window 90 and prevent the beverage from leaking from the cup by opening the scent window 90 too much.

Further, when the cover portion 40 that has been moved to the open position is returned to the closed position, the user may manually pull up the cover portion 40 to return the cover portion 40 to the closed position. This also makes it possible to switch from the closed position to the open position.

As described above, the beverage cup lid 100 can be made of a flexible member. Preferably, it is made of an inexpensive plastic having excellent flexibility. As a result, the cover portion 40 integrally formed with the lid main body 10 is held in the closed position when no external force is applied. Then, the cover portion 40 can be moved to the open position by pushing the lift-up convex portion 42 into the receiving portion 62. At this time, if the beverage cup lid 100 is elastic, the lift-up convex portion 42 can be easily pushed into the receiving portion 62. On the other hand, when the cover portion 40 is pulled out from the first fitting recess 60 and opened from the open position, it tends to return to the closed position due to elasticity.

Further, when the cover portion 40 is opened from the open position and the lift-up convex portion 42 is separated from the pushing piece 70, the pushing piece 70 also tries to return to the position of closing the scent window 90 due to elasticity. As a result, when the cover portion 40 is returned to the closed position and the opening portion 30 is closed, the scent window 90 is also closed.

As described above, according to the present invention, when the beverage cup is not used, the cover portion closes the opening which is the drinking port, so that the beverage does not spill from the beverage cup or, if it is a warm beverage, it is prevented from being cooled. Can be planned. Also, when using a beverage cup, the scent window is opened at the same time as the opening is opened. As a result, the scent of the beverage is leaked not only through the opening but also through the scent window. Therefore, the user can enjoy the scent of the beverage more than the usual beverage cup without the scent window with a simple one-push operation.

The beverage cup lid according to the present invention can be suitably used for various beverage cups. In particular, when the beverage is fragrant, for example, hot coffee, the fragrance can be enjoyed with a simple operation without worrying about the beverage leaking.
