Japanese Patent No. 2005-22757

However, in the conventional cup container with a lid, when the cutting blade member is pushed in with a finger, the finger may enter the cup body and touch the contents. There was a risk of becoming unsanitary.
In recent years, there has been an increasing demand for improving the opening performance by reducing the force required to open the cup container with a lid.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a cup container with a lid that is hygienic and has a good openability.

In order to solve the above problems and achieve such an object, the cup container with a lid according to the present invention is a cut-off piece that breaks and opens the sealing member in a cup body whose opening is sealed by the sealing member. A lidded cup container having a lid provided with a blade member, wherein the cutting blade member extends in an axial direction of the cup body and has a first hinge portion on a top wall portion of the lid. And a cutting edge projecting toward the sealing member side at the distal end portion with the base end portion being connected to the end portion on the sealing member side of the lever portion via the second hinge portion. And when the lever portion is rotated in a direction away from the cutting blade portion around the first hinge portion, the cutting blade moves forward toward the seal member. let is, the top wall portion when the support wall portion is protruded bets The lever portion is connected to the support wall portion via a first hinge portion, and when the lever portion is rotated around the first hinge portion in a direction away from the cutting blade portion, the lever portion However, when the support wall portion is pushed toward the seal member side, the top wall portion is depressed and deformed toward the seal member side .
In this invention, when the lever portion is rotated in the direction away from the cutting blade portion around the first hinge portion, the cutting blade is moved forward toward the seal member, whereby the cutting blade breaks the seal member. Therefore, in the process of opening the cup container with the lid, it becomes possible to gradually separate the finger that operates the lever portion from the opening portion that is broken by the cutting blade in the sealing member and opened. It is possible to prevent the finger from coming into the cup body at the time of opening and touching the contents.
Further, since the lever portion is rotated as described above at the time of opening, the lever action is exerted, and the force applied to the lever portion is directly applied by the finger as in the conventional cup container with a lid. Even if it is made smaller than the case of pushing in, the sealing member can be reliably broken by the cutting blade, and the opening property of the lid-equipped cup container can be improved.

Here, when the lever portion is rotated as described above, the top wall portion of the lid body can be depressed and deformed toward the seal member side. Even when the seal member is depressed and deformed toward the inside of the cup body from the opening so that a space is formed between the top wall and the seal member, the It becomes possible to reduce the space, and it is possible to prevent the contents from entering and accumulating in the space in the process of causing the contents to flow out from the opening portion of the seal member after opening.
Here, when the cup body is filled with high-temperature contents, the top wall is sealed in advance to prevent the top wall of the lid from bulging and deforming through the seal member due to the internal pressure of the cup body. If it is formed in a convex curved shape that bulges away from the member, the space before opening becomes larger, so that the above-described effects are remarkably achieved.

Moreover, the thin wall part which encloses a support wall part from the radial direction orthogonal to the said axis line may be formed in the said top wall part.
In this case, since the thin wall portion that surrounds the support wall portion from the outside in the radial direction is formed on the top wall portion of the lid, the top wall portion can be easily moved when the lever portion is rotated as described above. And it becomes possible to carry out depression deformation toward the sealing member side reliably. That is, it is possible to prevent the force applied to the lever portion from being increased at the time of opening in order to cause the top wall portion to be depressed and deformed.

  According to the cup container with a lid according to the present invention, it is possible to provide a hygienic and good openability.

  Embodiments of the present invention will be described below with reference to the drawings. The cup container 10 with a lid according to this embodiment includes a lid body 22 provided with a cutting blade member 21 that breaks and opens the seal member 12 on the cup body 11 whose opening 11a is sealed by the seal member 12.

And a formed cutting edge portion 30.

  In the illustrated example, the cutting blade member 21 has the lever portion 27 positioned away from the axis O to the outside in the radial direction, and the cutting blade 29 faces a part of the outer peripheral edge of the top wall portion 25 from above. As shown in FIG. Moreover, the cutting blade part 30 is extended toward upper direction gradually as it goes to the outer side of the said radial direction from the 2nd hinge part 28 side. The shape of the cutting blade member 21 in a longitudinal sectional view is a V-shape that is bent so that the second hinge portion 28 protrudes downward.

  And in the part facing the cutting blade member 21 in the top wall portion 25, when the lever portion 27 is rotated in the direction R away from the cutting blade portion 30 around the first hinge portion 26 as described later, A through hole 25a through which the cutting blade 29 passes and reaches the seal member 12 is formed. In the illustrated example, the through-hole 25a is formed in a rectangular shape when viewed from above, and its radially outer end reaches the outer peripheral surface of the top wall 25, and its radially inner end is the axis O. It is located on the outside in the radial direction.

  Further, a support wall portion 31 projects from a portion of the top wall portion 25 that continues to the through hole 25a in the radial direction. In the illustrated example, the support wall portion 31 extends continuously along the orthogonal direction A orthogonal to the direction in which the lever portion 27 and the cutting blade portion 30 are connected in a top view of the top wall portion 25. Yes. As shown in FIGS. 1 and 3, the support wall portion 31 is an inclined wall that gradually extends toward the through hole 25 a side, that is, toward the outer side in the radial direction as it goes upward. And the lower part of the lever part 27 in the cutting blade member 21 is connected via the 1st hinge part 26 to the part which faces the through-hole 25a side in the upper end part of this support wall part 31. FIG.

  Further, guide wall portions 32 project from both side portions of the top wall portion 25 that are continuous with the through holes 25a from both sides in the orthogonal direction A. In the illustrated example, the guide wall portion 32 is provided in a portion near the support wall portion 31 in the both side portions of the top wall portion 25. And between these guide wall parts 32, the edge part by the side of the 2nd hinge part 28 in the lower end part of the lever part 27, the 2nd hinge part 28, and the cutting blade part 30 is located. Furthermore, pins 33 project from the opposing surfaces of the guide wall portions 32 facing each other toward the cutting blade member 21, and these pins 33 are connected to the second hinge portion 28 in the cutting blade member 21. It is connected to each side surface of the part located between the cutting blades 29 separately. In the illustrated example, the pin 33 is connected to both side surfaces of the end portion on the second hinge portion 28 side in the cutting blade portion 30.

Next, a method of opening the cup container 10 with the lid configured as described above will be described.
First, the overcap 14 is removed from the lid 22, and then the lever portion 27 is rotated around the first hinge portion 26 in the direction R away from the cutting blade portion 30 as shown in FIG. 3. Then, while the cutting blade portion 30 is rotated around the pin 33 so that the cutting blade 29 moves downward, the second hinge portion 28 is moved upward, and the bending direction is opposite. become. In other words, the longitudinal sectional view of the cutting blade member 21 has an inverted V shape bent so that the second hinge portion 28 protrudes upward. Further, in this process, the cutting blade 29 passes through the through-hole 25a from the upper side to the lower side to reach the seal member 12, and the seal member 12 is broken to open the cup container 10 with the lid. . At this time, a part of the outer peripheral portion of the seal member 12 is opened.

  As described above, according to the cup container 10 with the lid according to this embodiment, when the lever portion 27 is rotated in the direction R away from the cutting blade portion 30 around the first hinge portion 26, the cutting blade 29 is provided. Is moved forward toward the seal member 12, and the cutting blade 29 breaks the seal member 12, so that the finger operating the lever portion 27 is opened in the process of opening the cup container 10 with the lid. The seal member 12 can be gradually separated from the portion that is broken and opened by the cutting blade 29, and the finger can be prevented from coming into contact with the contents by opening into the cup body 11 at the time of opening.

Further, since the lever portion 27 is rotated as described above at the time of opening, the lever action is exerted, and the force applied to the lever portion 27 is directly cut by a finger like the conventional cup container with a lid. Even if the blade is made smaller than the case where the blade is pushed in, the sealing member 12 can be reliably broken by the cutting blade 29, and the unsealing property of the cup container 10 with the lid can be improved.
Furthermore, since the top wall portion 25 of the lid body 22 is formed in a convex curved shape that bulges upward, the top wall portion 25 is placed in the cup body 11 when the cup body 11 is filled with high-temperature contents. It is possible to prevent the inner pressure from being bulged and deformed through the seal member 12.

The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
