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 adhering 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] However, in order to make the beverage container lid described in Patent Document 2 into a seesaw type, the peripheral side of the lifting drinking spout needs to be completely cut off by penetrating the plate of the cover plate, and there is a problem that the liquid of the beverage content may sway due to vibration during transportation, resulting in leakage. A possible method for solving this problem is to provide perforations or seams in various places without completely cutting off the peripheral side of the drinking spout. However, if a seam is provided on the lifting part of the seesaw type, it is necessary to apply a stronger pushing force with the finger, and when the seam is broken, the force of the finger will enter the pushing part, which will cause a problem that the advantage of the seesaw type drinking spout, that is, the easy opening operation can be performed even on a flush flat surface, is lost.

[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 that is free of risk of liquid leakage and allows the drinking spout to be easily opened, and a beverage container equipped with the lid. [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 which covers an opening of a beverage container, and a side peripheral portion which is provided on the outer peripheral edge of the cover plate portion and which can engage 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, and is characterized in that it comprises a push-in portion formed on the cover plate portion, surrounded by a cutting line portion which separates the cover plate portion, and which is pushed downward with a finger, and a lift-up portion formed on the cover plate portion adjacent to the push-in portion, surrounded by the cutting line portion, and which is lifted upward by the reaction force of the push-in portion being pushed downward, and a drinking spout portion is formed which is surrounded by a cut line which contains the push-in portion and the lift-up portion, and the cut line surrounding the drinking spout portion has a seam which penetrates the cover plate portion on the peripheral side adjacent to the side peripheral portion and is not separated.

[0014] The lid for a beverage container according to a second aspect of the present invention is the lid for a beverage container according to the first aspect of the present invention, characterized in that the width of the push-in portion is 7 mm or more and 15 mm or less.

[0015] The lid for a beverage container according to the third invention is characterized in that, in the first invention, the cover plate portion is formed with a locking portion into which the push-in portion is inserted and locked after the lift-up portion is pulled up to open the drinking spout portion.

[0016] The lid for a beverage container according to a fourth aspect of the present invention is the lid for a beverage container according to the first aspect of the present invention, characterized in that the pull-up portion is included within the cutting line portion of the push-in portion.

[0017] The lid for a beverage container according to the fifth invention is characterized in that, in the fourth invention, the cutting line portion of the push-in portion has a seam that penetrates the cover plate portion and acts as a swing hinge at the boundary with the pull-up portion, without being severed.

[0018] A beverage container according to a sixth 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 fifth aspects of the present invention. Effect of the Invention

[0019] According to the first to sixth inventions, a drinking spout portion is formed which is surrounded by a cut line which contains the push-in portion and the pull-up portion, and the cut line surrounding the drinking spout portion has a seam on the peripheral side, thereby reducing the risk of liquid leakage even if the contents beverage is shaken due to vibration during transportation, etc.

[0020] According to the first to sixth aspects of the invention, the spout portion having a seam can be easily opened by simply pressing the push-in portion with a finger and then pinching and pulling up the lifted-up portion that is lifted up by the reaction force. This makes it possible to achieve both reduced leakage and easy opening.

[0021] In particular, according to the second invention, the width of the push-in portion is between 7 mm and 15 mm, so that even if someone accidentally presses too hard, an average adult's finger will not be able to reach the first joint of the finger inside the push-in portion, preventing the seesaw-type pull-up portion (pull-up tab) from lifting up.

[0022] In particular, according to the third invention, a locking portion is formed into which the push-in portion is inserted and locked after the lift-up portion is pulled up to open the drinking spout portion, so that the opened drinking spout portion does not get in the way and the beverage can be drunk with the drinking spout portion fully open.

[0023] In particular, according to the fourth invention, since the pull-up portion is contained within the cutting line portion of the push-in portion, it is possible to prevent a situation in which a finger is mistakenly inserted into the pull-up portion, making it impossible to open the drinking spout portion.

[0024] In particular, according to the fifth invention, a joint is formed at the cutting line portion of the push-in portion, which acts as a swinging hinge for the swinging action that lifts the pull-up portion in a seesaw-like manner, so that the swinging action can be carried out reliably and the drinking spout portion having the joint can be easily opened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0027] <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.

[0028] 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.

[0029] 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, green tea, juice, etc.

[0030] 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.

[0031] 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.

[0032] <Lids for beverage containers> Next, a beverage container lid 1 according to an embodiment of the present invention will be described with reference to Figures 2 and 3. Figure 2 is a plan view showing the beverage container lid 1 according to the first embodiment, and Figure 3 is a partially enlarged plan view showing the drinking spout 6 of the beverage container lid 1. Figure 4 is a plan view showing the drinking spout 6 of the beverage container lid 1 with the drinking spout portion 9 fully open.

[0033] 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.

[0034] 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.

[0035] ((mouthpiece)) The cover plate 4 is formed with a drinking spout 6 that is opened by a push-and-pull system using a seesaw mechanism. The drinking spout 6 is made up of a push-in part 7 that is pushed downward with a finger, a pull-up part 8 that is lifted upward by the reaction force of the push-in part 7 being pushed downward, and a drinking spout part 9 that contains the push-in part 7 and the pull-up part 8.

[0036] (Push-in part) As shown in Figures 2 and 3, the pushing-in portion 7 is surrounded on three sides, excluding the adjacent pulling-up portion 8, by a cutting line portion 70 that penetrates the cover plate portion 4, and by pushing in this pushing-in portion 7, it has the function of lifting up the pulling-up portion 8 described below, which is continuous with the paperboard material of the cover plate portion 4, in a seesaw-like manner.

[0037] This cutting line portion 70 is composed of a straight line portion 71 extending in a direction perpendicular to the radial direction of the cover plate portion 4, and a pair of left and right arc-shaped side edges 72 folded back toward the periphery from both ends of this straight line portion 71, and has an inverted U-shape as a whole. The distance between the arc-shaped side edges 72 narrows from the base end portion on the straight line portion 71 side toward the center, and widens from the center to the tip, forming a symmetrical arc shape.

[0038] 3, the arc-shaped side edge 72 has a joint 73 that serves as a swing hinge at the boundary with the lifting portion 8 (on a straight line connecting the tips of the side edges 82, which will be described later). Here, the joint 73 is not limited to one in which the entire cross section of the paperboard material of the cover plate portion 4 is not cut, but refers to one in which a portion that penetrates the cover plate portion 4 and is not cut off (for example, a half cut, etc.).

[0039] The width W2 of the pressing portion 7 according to this embodiment is set to 15 mm. This is to prevent a situation in which the finger is pressed too hard into the pressing portion 7, preventing the seesaw-type lifting portion 8 from rising. However, in consideration of the range that can be pressed with the fingertip, the width W2 of the pressing portion 7 is preferably 7 mm or more, and in consideration of ease of pressing, it is more preferable that it is 10 mm or more. In consideration of preventing the first joint of the finger from entering the pressing portion 7 even if the finger is pressed too hard, it is preferable that it is 15 mm or less.

[0040] (Pulling up part) The pull-up portion 8 is surrounded on three of its four sides, excluding the adjacent push-in portion 7 side, by a cutting line portion 80 that penetrates the cover plate portion 4, and has the function of a pull-up tab that can be grasped and pulled up with the fingers to trigger the opening of the drinking spout portion 9 (described below).

[0041] As shown in Figure 3, this cutting line portion 80 is composed of a straight line portion 81 perpendicular to the radial direction of the cover plate portion 4, and a pair of straight side edges 82 folded back from both ends of this straight line portion 81 toward the center along the radial direction of the cover plate portion 4, and has an overall U-shape.

[0042] The pushing-in portion 7 and the pulling-up portion 8 move in unison in a seesaw-like manner, and the reaction force generated when the pushing-in portion 7 is pushed downward lifts the pulling-up portion 8 upward, and the lifted pulling-up portion 8 is then pulled up and used to open the drinking spout portion 9 described below.

[0043] (Drinking mouth part) The drinking spout 9 is configured such that it is surrounded on three of its four sides, excluding the center side, by cut lines 90 such as perforations or half cuts that are weaker than the general parts of the cover plate 4.

[0044] As shown in Figure 3, this cut line 90 is provided along the peripheral side of the side circumference 5, and is composed of an arc-shaped peripheral edge 91 which is the edge along which the beverage b actually passes when the beverage b is drunk, and a pair of straight side edges 92 on the left and right which are folded back at acute angles from both ends of this peripheral edge 91 toward the center, forming a tapered U-shape overall with the spacing narrowing toward the tip of the side edges 92.

[0045] 2 and 3, this cut line 90 contains the push-in portion 7 and the pull-up portion 8 inside the tapered U-shape, and the tip side of the side edge 82 of the pull-up portion 8 is continuous with the push-in portion 7 and the paperboard material of the cover plate portion 4, and the tip side of the side edge 72 of the push-in portion 7 is continuous with the drinking spout portion 9 and the paperboard material of the cover plate portion 4. When the pull-up portion 8 is pulled up, the cut line 90 is completely cut and the drinking spout portion 9 is opened.

[0046] A seam 93 is provided on the peripheral edge 91 of the cut line 90 surrounding the spout 9, connecting the peripheral edge 91 of the spout 9 to the outer cover plate 4. This reduces the risk of liquid leakage even if the beverage b contained therein is shaken due to vibration during transportation of the beverage container 2. Note that the seam 93, like the seam 73, is not limited to one in which the entire cross section of the paperboard material of the cover plate 4 is not cut, but refers to one in which a portion penetrates the cover plate 4 and is not cut. If the seam is not cut even partially, the peripheral edge 91 will not lift up and open on its own due to vibration during transportation.

[0047] ((Latching part)) 1 and 2, the cover plate 4 is formed with a locking portion 10 consisting of an H-shaped notch in a plan view. As shown in FIG. 4, this locking portion 10 has the function of inserting and locking the push-in portion 7 after the pull-up portion 8 is pulled up to open the drinking spout portion 9.

[0048] As shown in Fig. 2, the width W1 of the locking portion 10 is set slightly narrower than the width W2 of the push-in portion 7 shown in Fig. 3. Therefore, the locking portion 10 can latch and lock the push-in portion 7 and the drinking spout portion 9 connected to the push-in portion 7 by sandwiching the push-in portion 7 with the H-shaped slit slightly widened in the center. Note that the slit of the locking portion 10 is not limited to a slit that penetrates the entire cover plate portion 4, and may be a low-strength portion that is weaker than the general portion of the cover plate portion 4, such as a perforation or half cut that partially cuts the cross section of the paperboard material of the cover plate portion 4.

[0049] <How to open the drinking spout of a beverage container lid> Next, a method for opening the drinking spout 6 of the lid 1 for a beverage container according to the embodiment of the present invention will be described with reference to Figs. 5 to 11 and 4.

[0050] (Push-in part pushing process) Fig. 5 is a partially enlarged plan view showing the spout 6 in the push-in part pushing step of the method for opening the spout according to this embodiment, and Fig. 6 is a partially enlarged perspective view showing the spout in the push-in part pushing step of the method for opening the spout according to this embodiment. Note that the diagonal lines in the figure indicate the opened part of the spout 6.

[0051] As shown in Figures 5 and 6, in the method for opening the drinking spout according to this embodiment, first, a push-in portion pushing step is performed in which the push-in portion 7 is pushed in to lift up the straight portion 81 side of the pull-up portion 8, which is a pull-up tab.

[0052] In this process, as shown in Figures 5 and 6, when the center of the pressing-in portion 7 is pressed in with a finger, the pressing-in portion 7 is surrounded by a cutting line portion 70 that cuts through the cover plate portion 4 from the joint 73 to the center, so that the joint 73 becomes a rotating hinge and is pressed down further than the other cover plate portion 4.

[0053] On the other hand, the lifting portion 8 connected to the pushing-in portion 7 is surrounded on its peripheral side by a cutting line portion 80 that penetrates and cuts through the cover plate portion 4, so that the reaction force generated when the pushing-in portion 7 is pushed in causes the straight line connecting the tips of the side edges 82 (the joints 73) to rise up on the straight line portion 81 side, which acts as a rotation axis (rotation hinge).

[0054] However, even if the straight line connecting the tips of the side edges 82 is shifted toward the periphery or center from the straight line connecting the joints 73, it is possible to use the straight line connecting the tips of the side edges 82 as a rotation hinge to pull up the pull-up portion 8. For this reason, even if the straight line connecting the tips of the side edges 82 and the straight line connecting the joints 73 do not completely match, it is sufficient if they are close to each other by a few millimeters. This is because it is possible to push in the push-in portion 7 and lift up the straight line portion 81 side of the pull-up portion 8, which is a pull-up tab.

[0055] (Pulling up process) Figure 7 is a partially enlarged plan view showing the drinking spout 6 during the lifting-up portion lifting step of the method for opening the drinking spout in this embodiment, and Figure 8 is a partially enlarged oblique view showing the drinking spout during the lifting-up portion lifting step of the method for opening the drinking spout 6 in this embodiment.

[0056] As shown in Figs. 7 and 8, next, in the method for opening a drinking spout according to this embodiment, a step of lifting up the lifted part is carried out in which the lifted part 8 lifted up in the previous step is pinched with fingers and lifted up.

[0057] In this process, as shown in Figures 7 and 8, the pulling-up portion 8 is pinched with fingers and pulled up, thereby cutting the seam 73 of the push-in portion 7, and raising the push-in portion 7 on the peripheral side from the seam 73 along the cutting line 70 to the tip of the side edge 72.

[0058] (Spout opening process) Figure 9 is a partially enlarged plan view showing the drinking spout 6 during the drinking spout opening step of the method for opening a drinking spout in this embodiment, and Figure 10 is a partially enlarged oblique view showing the drinking spout 6 during the drinking spout opening step of the method for opening a drinking spout in this embodiment.

[0059] As shown in Figures 9 and 10, next, in the method for opening a drinking spout according to this embodiment, a drinking spout opening process is performed in which the push-in portion 7, which was pulled up to the tip of the side edge 72 in the previous process, is further pulled up to open the drinking spout portion 9.

[0060] In this process, as shown in Figures 9 and 10, the pulled-up portion 8 is pinched with fingers and pulled up, thereby cutting the seam 93 (see also Figures 7 and 8), cutting the peripheral edge 91, and then by continuing to pull up the pulled-up portion 8, cutting the side edge 92 of the cut line 90 all the way to the tip, and opening the drinking spout portion 9.

[0061] At this time, in order to open the drinking spout 9 by lifting it with a light force, it is preferable that the tip of the side edge 72, which is the starting point for lifting, is on the peripheral side of the drinking spout 6. Furthermore, in order to be able to lift the drinking spout 9, it is necessary that the straight line connecting the tips of the side edges 72 is at least closer to the peripheral side than the straight line connecting the tips of the side edges 92.

[0062] In addition, in this process, the pull-up portion 8, which is a pull-up tab, is pinched with the fingers and pulled up to open, so compared to when pushing to open, the drinking spout portion 9 can be opened while holding down the side periphery 5 of the beverage container lid 1 with the hand that is not pinching. Moreover, the trigger for opening the flat cover plate portion 4 of the beverage container lid 1 is the action of pushing in the push-in portion 7 and lifting the straight portion 81 side of the pull-up portion 8 in a seesaw fashion, so anyone can intuitively understand this.

[0063] (Drink spout locking process) Figure 11 is a partially enlarged oblique view showing the drinking spout 6 in the drinking spout locking step of the drinking spout opening method of this embodiment, and Figure 4 is a plan view showing the drinking spout 6 of the beverage container lid 1 in a fully open state with the drinking spout portion 9 engaged with the push-in portion 7 in the drinking spout locking step of the drinking spout opening method of this embodiment.

[0064] Next, in the method for opening the drinking spout according to this embodiment, as shown in FIG. 11, a drinking spout locking process is performed in which the drinking spout portion 9 opened in the previous process is latched and locked by inserting the pushing portion 7 into the aforementioned locking portion 10.

[0065] As mentioned above, the width W1 of the engagement portion 10 is set slightly narrower than the width W2 of the push-in portion 7, and the position at which the engagement portion 10 is provided is set such that the distance from the drinking spout 6 allows the push-in portion 7 to be inserted when the drinking spout portion 9, which has been cut off along the cut line 90, is just stretched out. As a result, the opened drinking spout portion 9 does not get in the way, and beverage b can be drunk with the drinking spout portion 9 fully open.

[0066] According to the lid 1 for a beverage container of the embodiment of the present invention described above, a drinking spout portion 9 is formed which is surrounded by a cut line which contains the push-in portion 7 and the pull-up portion 8, and the cut line surrounding the drinking spout portion 9 has a seam 93 on the peripheral side, thereby reducing the risk of liquid leakage even if the contents (beverage b) are shaken due to vibration during transportation, etc.

[0067] Furthermore, according to the lid 1 for beverage containers, the drinking spout portion 9 having the seam 93 can be easily opened by simply pressing the pushing-in portion 7 with a finger and then pinching and pulling up the lifting portion 8 that is lifted up by the reaction force. This makes it possible to achieve both reduced leakage and easy opening.

[0068] Furthermore, according to beverage container lid 1, the width W2 of push-in portion 7 is 15 mm or less, so that even if an adult accidentally presses too hard, the finger cannot reach the first joint of the finger of an average adult and the seesaw-type lift-up portion 8 cannot be lifted up.

[0069] Furthermore, according to the lid 1 for beverage containers, after the lifting part 8 is pulled up to open the drinking spout part 9, a locking part 10 is formed into which the pushing part 7 is inserted and locked, so that the opened drinking spout part 9 does not get in the way and the beverage can be drunk with the drinking spout part 9 in a fully open state.

[0070] Although the beverage container lid 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 these.

[0071] In particular, the beverage container lid 1 and beverage container 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.
