Description

[Technical field]

[0001] The present invention relates to a lid for a beverage container which covers an opening of the beverage container, and a beverage container provided with the lid. [Background technology]

[0002] Conventionally, many beverage retailers, such as fast food restaurants and convenience stores, sell beverage containers, such as plastic (synthetic resin) or paper cups, with beverage container lids that cover the openings to prevent the juice, coffee, or other beverages contained inside from spilling out of the opening when the containers are carried.

[0003] To drink the beverage contained inside the beverage container, one can simply remove the beverage container lid and drink from the opening, but when the beverage container lid is removed, the beverage that has adhered to the inside of the lid may splash out, potentially staining the drinker's clothes, etc.

[0004] For example, Patent Document 1 discloses a lid for a beverage container that has a straw insertion portion in which an attached straw can be inserted to make it easier to drink the beverage inside the beverage container (see claim 1 in the claims of Patent Document 1, paragraphs

[0036] to

[0058] of the specification, Figures 1 to 7 of the drawings, etc.).

[0005] However, in recent years, triggered by issues such as marine pollution caused by plastic waste, there has been a growing global movement to move away from plastic, and as part of this, there is also a growing movement to eliminate plastic straws.

[0006] Under these circumstances, there is a demand in the market for a beverage container lid that does not require a straw and can form a drinking spout that makes it easy to drink a beverage without removing the beverage container lid. For this reason, in addition to the technology disclosed in Patent Document 1, a push-down type has also been proposed in which the drinking spout is formed by making a valley fold in the part of the beverage container lid that forms the drinking spout.

[0007] However, this push-down type requires consumers to perform a two-step opening action to form the drinking spout, which makes it difficult for consumers to intuitively understand how to form the drinking spout. For this reason, there has been a demand for a beverage container lid that simplifies the opening action itself so that it can be achieved in one step, allowing consumers to intuitively understand how to form the drinking spout.

[0008] Therefore, in Patent Document 2, a beverage container lid 1 was developed in which a drinking spout (drinking spout 110) is formed consisting of a push-in portion, that is, a portion for opening the drinking spout 12A and a portion for forming the drinking spout 11A, separated by a linear perforation (low-strength portion for folding 14), and a seesaw-type (push-up type) drinking spout is formed in which the drinking spout can be opened by pushing down the portion for opening the drinking spout 12A with a finger and lifting the portion for forming the drinking spout 11A in reaction (see claim 1 in the claims of Patent Document 2, paragraphs

[0024] to

[0036] of the specification, Figures 2 to 4 of the drawings, etc.).

[0009] A seesaw-type drinking spout, such as the lid for a beverage container described in Patent Document 2, can be opened in a single step by simply pressing down on the pressing part with a finger, making it easy for consumers to intuitively understand how to form the drinking spout, and has the advantage that anyone can quickly open the drinking spout even without an instruction manual.

[0010] In addition, the lid for a beverage container described in Patent Document 2 has a slit formed in the engagement portion 13, and has a mouth shape. The drinking spout 110 can be held in an open state by inserting and engaging the locking portion 11a around the periphery of the use portion 11A into the engagement portion 13. However, although the beverage container lid described in Patent Document 2 can hold the drinking spout 110 in an open state, there is a problem in that the area around the nose is sealed while drinking a beverage from the drinking spout, making it impossible to enjoy the aroma of the beverage.

[0011] [Patent Document 1] JP 2021-14286 A [Patent Document 2] JP 2023-6268 A Summary of the Invention [Problem to be solved by the invention]

[0012] The present invention has been devised in consideration of the above-mentioned background, and its object is to provide a lid for a beverage container, and a beverage container equipped with the lid, which allows the drinking spout to be opened in one step and allows the aroma of the beverage to be enjoyed. [Means for solving the problem]

[0013] The lid for a beverage container according to the first invention is a lid for a beverage container comprising a cover plate portion for covering an opening of a beverage container, and a side periphery portion provided on the outer periphery of the cover plate portion and capable of engaging with the edge of the opening of the beverage container when the cover plate portion is adapted to cover the opening of the beverage container, the lid further comprising a push-in portion formed on the cover plate portion and surrounded by a cutting line portion consisting of a low-strength portion or a cut line portion having a lower strength than a general portion of the cover plate portion, the push-in portion being pushed downward with a finger, and a cut line portion formed on the cover plate portion adjacent to the push-in portion and surrounding the low-strength portion or the cut line portion. and a drinking spout portion that is surrounded by a cutting line portion consisting of the low-strength portion and is lifted upward by a reaction force caused by the push-in portion being pushed downward, wherein the drinking spout portion is located closer to the side periphery than the push-in portion, the boundary between the drinking spout portion and the push-in portion is partitioned by a dividing line portion consisting of the low-strength portion or the cut line portion, the width of the push-in portion is wider than the width of the drinking spout portion, and the distance from the dividing line portion to the end of the drinking spout portion on the side periphery side is longer than the distance from the dividing line portion to the end of the push-in portion on the central side.

[0014] The lid for a beverage container according to the second invention is characterized in that, in the first invention, the cover plate portion is formed with a locking portion for locking the drinking spout portion, and even when the opened drinking spout portion is locked in the locking portion by pushing the push-in portion downward, a portion of the push-in portion remains open as a fragrance window.

[0015] The lid for a beverage container according to a third aspect of the present invention is characterized in that in the second aspect, the locking portion is also formed by one side of a cutting line portion surrounding the push-in portion.

[0016] The lid for a beverage container of the fourth invention is characterized in that, in the first invention, the drinking spout end, which is the end of the cutting line portion surrounding the drinking spout, and the push-in end, which is the end of the cutting line portion surrounding the push-in portion, are spaced apart from each other, the drinking spout end is not on an extension of the cutting line portion surrounding the push-in portion, and the push-in end is not on an extension of the cutting line portion surrounding the drinking spout.

[0017] A beverage container according to a fifth aspect of the present invention is characterized by comprising a container body and a beverage container lid according to any one of the first to fourth aspects of the present invention. Effect of the Invention

[0018] According to the first to fifth inventions, the drinking spout is a seesaw type, so it can be opened in one step by simply pressing down on the push-in part with a finger, making it easy for consumers to intuitively understand how to form the drinking spout, and anyone can quickly open the drinking spout even without an instruction manual.

[0019] In addition, according to the first to fifth inventions, the width of the push-in portion is wider than the width of the drinking spout portion, and the distance from the dividing line portion to the end portion on the side periphery side of the drinking spout portion is longer than the distance from the upper drawing line portion to the end portion on the central side of the pushed-in portion, so that the aroma of the beverage can be enjoyed through the gap between the width of the drinking spout portion and the width of the pushed-in portion.

[0020] In particular, according to the second invention, even when the drinking spout portion is engaged with the engaging portion, a portion of the push-in portion remains open as an aroma window, so that a beverage can be drunk with the drinking spout portion fully open and the aroma of the beverage can be enjoyed.

[0021] In particular, according to the third invention, one side of the cutting line portion surrounding the push-in portion doubles as the locking portion, so there is no need to provide a locking portion on the cover plate portion separate from the push-in portion, and the above-mentioned effects can be achieved while reducing manufacturing costs.

[0022] According to the fourth invention, the drinking spout end and the push-in portion end are spaced apart from each other, the drinking spout end is not on an extension of the cutting line portion of the push-in portion, and the push-in portion end is not on an extension of the cutting line portion of the drinking spout portion, so that the hinge portion is unlikely to break even if the push-in portion is pressed hard when opening the drinking spout portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0025] <Beverage container> First, a beverage container 2 according to an embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is an exploded perspective view of the beverage container 2 according to an embodiment of the present invention.

[0026] A beverage container 2 according to an embodiment of the present invention includes a paper container body 3 and a beverage container lid 1 according to an embodiment of the present invention fitted onto this container body 3, as shown in FIG.

[0027] The container body 3 is a paper cup with a bottom that has an opening 3a with a rim 3b at its upper part and expands in diameter like an inverted truncated cone as it goes upwards, and is often used to store and sell beverages b such as coffee, black tea, and green tea inside.

[0028] The container body 3 is not limited to being made of paper, and may be made of other materials such as plastic. However, using paper for the container body 3 is preferable because it not only reduces the amount of plastic used, but also makes it easy to melt into pulp and recycle, and can be incinerated, eliminating the problem of microplastics. If the container body 3 is made of plastic, it is preferable to use an environmentally friendly biodegradable plastic.

[0029] This beverage container 2 is closed by fitting a beverage container lid 1, which will be described later, onto the edge 3b of the opening 3a of the container body 3, making it easy to transport the container with the beverage b inside, and the container can be displayed and sold in various stores, etc. as a packaging container.

[0030] <Lids for beverage containers> [First embodiment] Next, the lid 1 for beverage containers according to the first embodiment of the present invention will be described with reference to Fig. 2 to Fig. 5. Fig. 2 is a plan view showing the lid 1 for beverage containers according to the first embodiment, and Fig. 3 is a partially enlarged plan view showing the drinking spout 6 of the lid 1 for beverage containers. Fig. 4 is a plan view showing the drinking spout 6 of the lid 1 for beverage containers with the drinking spout portion 8 fully open.

[0031] As shown in Figure 2, the lid 1 for a beverage container is a single-piece drawn paper lid and includes a disk-shaped covering plate portion 4 that covers the opening 3a of the beverage container 2, and a side peripheral portion 5 that is provided on the outer periphery of the covering plate portion 4 and can engage with the edge portion 3b of the opening 3a of the beverage container 2 when the covering plate portion 4 is arranged to cover the opening 3a of the beverage container 2.

[0032] The beverage container lid 1 is not limited to being made of paper, and may be made of other materials such as plastic. However, the beverage container lid 1 is preferably made of paper, since it can be easily recycled by melting it into pulp and can be incinerated, which solves the problem of microplastics. If the beverage container lid 1 is made of plastic, an environmentally friendly biodegradable plastic may be used.

[0033] (Taste) In addition, a seesaw-type (push-up type) drinking spout 6 is formed on the cover plate 4. This drinking spout 6 is composed of a push-in part 7 that is pushed downward with a finger, and a drinking spout part 8 that is lifted upward by the reaction force of the push-in part 7 being pushed downward, and the drinking spout part 8 is located closer to the side periphery part 5 (periphery side) than the push-in part 7.

[0034] The push-in portion 7 is configured to be surrounded on three of the four sides, except for one side adjacent to the drinking spout portion 8, by a cutting line portion 70 consisting of a cut line portion cut through the cover plate portion 4. However, the cutting line portion 70 does not have to be a cut line portion cut all the way through the cover plate portion 4, and may be a low-strength portion having lower strength than the general portion of the cover plate portion 4, such as a perforation, half cut, or crease that partially cuts the cross section of the paperboard material of the cover plate portion 4.

[0035] As shown in Figure 3, this cutting line portion 70 is composed of a straight-line hook edge 71 that extends perpendicular to the radial direction of the cover plate portion 4 and hooks the drinking spout portion 8, which also serves as the engagement portion described below, and a pair of arc-shaped side edges 72 that are folded back from both ends of the hook edge 71 toward the periphery.

[0036] The drinking spout 8 is configured such that it is surrounded on three of its four sides, except for one of the sides adjacent to the push-in section 7, by a cutting line section 80 consisting of a cutting line section cut through the cover plate section 4. However, like the cutting line section 70 described above, the cutting line section 80 does not have to be a cutting line section cut all the way through the cover plate section 4, but may be a low-strength section that has lower strength than the general section of the cover plate section 4, such as a perforation, half cut, or crease that partially cuts the cross section of the paperboard material of the cover plate section 4.

[0037] As shown in Figure 3, this cutting line portion 80 is provided on the peripheral side along the side peripheral portion 5 and is composed of an arc-shaped peripheral edge 81 which is the edge along which the beverage b actually passes when the beverage b is drunk, and a pair of left and right straight side edges 82 which are folded back from both ends of this peripheral edge 81 toward the center along the radial direction of the cover plate portion 4, forming an overall U-shape.

[0038] 2 and 3, the boundary between the push-in portion 7 and the mouth portion 8 is defined by a dividing line portion 9. This dividing line portion 9 is made of a cut line portion cut through the cover plate portion 4, but it may also be a linear low-strength portion that connects the ends of the cut line portion 80 and has lower strength than the general portion of the cover plate portion 4, such as the half cut or crease described above. However, since the push-in portion 7 and the mouth portion 8 need to move in conjunction with each other like a seesaw, it is preferable that a portion where the entire cross section of the paperboard material of the cover plate portion 4 at the boundary between the push-in portion 7 and the mouth portion 8 is continuously connected remains, as in the illustrated form.

[0039] 3, the width W1 of the push-in portion 7 is wider than the width W2 of the drinking spout portion 8, and the distance D2 from the dividing line portion 9 to the end of the drinking spout portion 8 on the side periphery side is longer than the distance D1 from the dividing line portion 9 to the end of the pushing-in portion 7 on the central side. Therefore, as shown in FIG. 4, the drinking spout portion 8 is folded in a valley fold along the dividing line portion 9, and the peripheral edge 81 of the drinking spout portion 8 is inserted under the hook edge 71 (the edge of the cover plate portion 4) on the central side (opposite the side periphery) of the pushing-in portion 7 to serve as a locking portion for locking, and the beverage b can be drunk from the drinking spout portion 8 in the fully open state without pressing it with a finger.

[0040] Although the side 72 of the push-in portion 7 has been described as being arc-shaped, the side 72 may also be linear. However, the width W1 of the side 72 of the push-in portion 7 needs to be wider than the width W2 of the spout portion 8, which is the distance between the side edges 82. This is to provide an aroma window for drinking highly fragrant beverages such as coffee, black tea, and green tea from the spout portion 8 through the gap between the width W1 of the push-in portion 7 and the width W2 of the spout portion 8.

[0041] (Hinge part) 3, the push-in portion end 73, which is the end of the side edge 72 of the cutting line portion 70 of the push-in portion 7, and the drinking spout portion end 83, which is the end of the side edge 82 of the cutting line portion 80 of the drinking spout portion 8, are spaced a specified distance (3 mm in this embodiment). This is because the space between the push-in portion end 73 and the drinking spout portion end 83 becomes a hinge portion when the push-in portion 7 is pushed in with a finger to open the drinking spout portion 8, that is, when the push-in portion 7 and the drinking spout portion 8 are rotated in a seesaw manner, and if the paperboard material of the cover plate portion 4 is not left a certain distance, this hinge portion will be twisted and broken when rotated.

[0042] Next, the hinge portion will be described in more detail with reference to Fig. 5. Fig. 5(a) is an enlarged view of part A of the hinge portion of the lid 1 for beverage containers in Fig. 3, and Fig. 5(b) is a schematic cross-sectional view of the hinge portion of the lid 1 for beverage containers. The reason why the hinge portion of the seesaw-type drinking spout 6 breaks is that, as shown in Fig. 5(b), if the positions of the drinking spout end 83, which is the fulcrum of the seesaw (lever), and the pushing-in end 73 are apart in the vertical cross section of the cover plate 4, the pushing-in end 73, which is the starting point of the pushing-in, tries to approach the drinking spout end 83, which is the starting point of the rising, and the hinge portion connecting them breaks. That is, the cut portion of the paperboard material of the cutting line portion 80 (cutting line portion 70) extends from the drinking spout end 83 along the dotted line X and breaks when it reaches the pushing-in end 73. Similarly, when the cut portion of the paperboard material at the cutting line portion 70 extends from the push-in portion end 73 along the dotted line Y and reaches the drinking spout portion end 83, the hinge portion breaks.

[0043] However, as shown in FIG. 5(a), in the beverage container lid 1 according to this embodiment, the push-in end 73 is not on the extension of the cutting line 80 surrounding the spout 8, i.e., on the extension of the straight side 82 (it is in the part excluding the extension line; the same applies below). Therefore, even if the cut part of the paperboard material of the cutting line 80 extends along the dotted line X, it does not reach the push-in end 73, the paperboard material of the cover plate 4 remains, and the hinge portion does not break completely. Similarly, the spout end 83 is not on the extension of the cutting line 70 of the push-in portion 7, i.e., on the extension (tangent) of the arc-shaped side 72. Therefore, even if the cut part of the paperboard material of the cutting line 70 extends along the dotted line Y, it does not reach the spout end 83, the paperboard material of the cover plate 4 remains, and the hinge portion does not break completely.

[0044] [Second embodiment] Next, a beverage container lid 1' according to a second embodiment of the present invention will be described with reference to Fig. 6 to Fig. 8. Fig. 6 is a plan view showing the beverage container lid 1' according to the second embodiment, and Fig. 7 is a partially enlarged plan view showing the drinking spout 6' of the beverage container lid 1'. Fig. 8 is a plan view showing the drinking spout 6' of the beverage container lid 1 with the drinking spout portion 8 fully open.

[0045] The difference between the beverage container lid 1' of the second embodiment and the beverage container lid 1 of the first embodiment described above is the shape of the push-in portion 7' ​​and the provision of a new locking portion 10. Therefore, this point will be mainly explained, and the same components will be given the same symbols and detailed explanations will be omitted.

[0046] (Taste) As shown in Figures 6 to 8, the cover plate 4 of the beverage container lid 1' is formed with a seesaw type (push-up type) drinking spout 6', similar to the beverage container lid 1. This drinking spout 6' is composed of a push-in portion 7' ​​that is pushed downward with a finger, and a drinking spout portion 8 that is lifted upward by the reaction force of the push-in portion 7' ​​being pushed downward, and the drinking spout portion 8 is located closer to the side periphery 5 than the push-in portion 7.

[0047] (Push-in part) Like the push-in portion 7, the push-in portion 7' ​​is configured to be surrounded on three of its four sides, except for one side adjacent to the drinking spout portion 8, by a cutting line portion 70' consisting of a cut line portion cut through the cover plate portion 4. However, the cutting line portion 70' does not have to be a cut line portion cut through the entire cover plate portion 4, and may be a low-strength portion having lower strength than the general portion of the cover plate portion 4, such as a perforation, half cut, or crease that partially cuts the cross section of the paperboard material of the cover plate portion 4.

[0048] As shown in Figures 6 and 7, this cutting line portion 70' is composed of a straight line portion 71' extending perpendicular to the radial direction of the cover plate portion 4, and a pair of semicircular side edges 72' folded back toward the periphery from both ends of this straight line portion 71'.

[0049] Also, as shown in FIG. 7, in the beverage container lid 1', the push-in end 73' is not on the extension line of the cutting line 80 surrounding the spout 8, i.e., on the extension line of the straight side edge 82. Therefore, even if the cut part of the paperboard material of the cutting line 80 extends along the side edge 82, it does not reach the push-in end 73', the paperboard material of the cover plate 4 remains, and the hinge portion does not break completely. Similarly, the spout end 83 is not on the extension line of the cutting line 70' of the push-in portion 7', i.e., on the extension line (tangent) of the arc-shaped side edge 72'. Therefore, even if the cut part of the paperboard material of the cutting line 70' extends along the tangent line of the semicircular side edge 72', it does not reach the spout end 83, the paperboard material of the cover plate 4 remains, and the hinge portion does not break completely.

[0050] (Latching part) 6 and 7, the cover plate 4 of the beverage container lid 1' is formed with a locking portion 10 for locking the peripheral edge 81 of the spout 8. The locking portion 10 is made of a cut line that is cut through the cover plate 4 into a U-shaped cut line, and is set to a length of about width W2 that allows the spout 8 to be inserted therethrough.

[0051] Furthermore, as shown in FIG. 8, even when the drinking spout 8 is engaged with the engaging portion 10, the semicircular side edge 72' of the beverage container lid 1' protrudes to the left and right from the side edge 82 of the drinking spout 8. This means that when the pressed-in portion 7' ​​is pushed open, a portion of the pressed-in portion 7' ​​is opened as an aroma window, allowing the user to drink the beverage b with the drinking spout 8 fully open and enjoy the aroma of the beverage b.

[0052] According to the lid for beverage containers 1,1' of the embodiment of the present invention described above, the drinking spout 6,6' is a seesaw type, so it can be opened in one step by simply pressing down the push-in portion 7,7' with a finger, making it easy for consumers to intuitively understand how to form the drinking spout, and anyone can quickly open the drinking spout even without an instruction manual.

[0053] Furthermore, according to the lid 1,1' for a beverage container, the width W1, W1' of the push-in portion 7, 7' is wider than the width W2 of the drinking spout portion 8, and the distance D2 from the dividing line portion 9 to the end of the drinking spout portion 8 on the side periphery 5 side (peripheral edge side) is longer than the distance D1, D1' from the dividing line portion 9 to the end of the push-in portion 7, 7' on the central side. Therefore, if the beverage b is a highly fragrant beverage such as coffee, black tea, or green tea, the aroma of the beverage b can be enjoyed through the gap created by the difference between the width W2 of the drinking spout portion 8 and the width W1, W1' of the push-in portion 7, 7' (see Figures 3, 4, 7, and 8).

[0054] Furthermore, according to the lid 1, 1' for a beverage container, even when the drinking spout portion 8 is engaged with the engagement portion 10 and the latching edge 71, a portion of the push-in portion 7, 7' remains open as an aroma window, so that the beverage b can be drunk with the drinking spout portion 8 fully open and the aroma of the beverage b can be enjoyed.

[0055] Although the beverage container lid 1, 1' and the beverage container 2 according to the embodiment of the present invention have been described in detail above, the above-mentioned and illustrated embodiments are merely specific embodiments for carrying out the present invention, and therefore the technical scope of the present invention should not be interpreted as being limited by them.

[0056] In particular, the beverage container lids 1, 1' and beverage containers 2 have been described as being made of paper with paper as the primary raw material, but the present invention can also be applied to items that have the same shape but different sheet materials, such as plastic caps.

[0057] In addition, the push-in portions 7, 7' are symmetrical in the above example, but one side 72' of the push-in portion 7' ​​may be semicircular and the other side may be linear, as shown in Fig. 9. This is because the aroma of the beverage b can be enjoyed with only one aroma window.

[0058] Furthermore, as shown in Fig. 10, the push-in part 7 may be bulging toward the center instead of bulging left and right. Due to the difference in shape between the push-in part 7 and the drinking spout part 8, the aroma of the beverage b can be enjoyed even if the aroma window is provided in the center instead of on the left and right.
