JP 2005-22757 A

  However, the following problems remain in the conventional lidded cup container. That is, when the cutting blade member is pushed with a finger, the finger may enter the cup body and the contents may adhere to the finger. Further, when the cutting blade member is pressed more strongly than necessary, there is a risk that the cutting blade member, fingers or the like will enter the contents vigorously and the contents will be scattered outside. Furthermore, since the cutting blade provided in the outlet part of the lid is pushed in with a finger or the like, the finger touches the outlet part. For this reason, there exists a hygiene problem especially when the contents are foods such as beverages.

  The present invention has been made in view of the above-described problems, and can prevent the contents from scattering to the outside and adhering to the finger, etc., and the finger touches the outlet portion when opening with the cutting blade member. An object of the present invention is to provide a cup container with a lid that is hygienic without any problems. Moreover, it aims at providing the cup container with a lid | cover which can improve the hygiene side in case the contents are foodstuffs.

  The present invention employs the following means in order to solve the above problems. That is, the lid-equipped cup container of the present invention is provided with a cup body whose open end is sealed by a sealing member, and a cutting blade member that breaks and opens the sealing member, and is attached to the cup body. A cup container with a lid, wherein the cutting blade member is formed on a rotating plate coupled to a top surface portion of the lid body via a hinge portion, and a lower surface of the rotating plate. A pressing portion for rotating the cutting blade member around the hinge portion, and an outlet portion formed away from the pressing portion is formed on the rotating plate. When the pressing portion is pressed, the cutting blade member rotates around the hinge portion from an upright state where the cutting blade member stands up with respect to the top surface portion to a closed state where the opening formed in the top surface portion is closed. The sealing member is broken.

  In this invention, since the cutting blade member is opened in the closed state, the contents are less likely to scatter to the outside from the portion other than the outlet portion, and the pressing portion and the outlet portion are separated from each other. Hygienic because no fingers touch the part. That is, since the rotating plate closes the opening at the time of opening, when the cup body is tilted and the contents are taken out, the contents are hardly scattered or leaked from outside the outlet part. And it becomes difficult for the content scattered on a finger etc. to adhere. Further, when the cutting blade portion breaks and opens the sealing member, a finger or the like that is pressing the pressing portion does not touch the outlet portion. For this reason, it is hygienic when the contents are taken out via the take-out port. Therefore, it is possible to prevent the contents from being scattered and leaked and to be hygienic.

In the cup container with a lid of the present invention, it is preferable that the lid body has an upright state holding portion that holds the upright state of the cutting blade member.
In this invention, it can suppress that a sealing member is opened accidentally by the vibration at the time of distribution | circulation, etc.

In the cup container with a lid of the present invention, it is preferable that the lid body has a closed state holding portion that holds the closed state of the cutting blade member.
In this invention, when the cup body is tilted and the contents are taken out, it is possible to prevent the contents from leaking out from the portion other than the outlet portion due to the rotation plate turning. In addition, when the pressing portion is pressed, it is possible to more reliably prevent the rotating plate from rotating below the top surface portion and fingers and the like from entering the cup body.

Further, in the cup container with a lid according to the present invention, the cutting blade member rotates the cutting blade member from a standing state in which the cutting blade member stands with respect to the top surface portion to a closed state in which the opening formed in the top surface portion is closed. Thus, it is preferable to have a sub cutting edge portion that rotates around the hinge portion and breaks the seal member.
In this invention, since the sealing member is broken at a plurality of locations, the contents in the cup body can be taken out smoothly. That is, the content is taken out through the opening formed in the seal member by the cutting blade portion, but when the opening formed by the cutting blade portion is blocked by the flow of the content, the content is changed by the change in the internal pressure of the cup body. It becomes difficult for an object to circulate through the opening formed by the cutting edge portion. Here, in addition to the opening formed by the cutting blade portion, another opening is formed in the seal member by the sub cutting blade portion, so that air can be circulated from the other opening into the cup body. Thereby, even if an opening is obstruct | occluded with the content, the internal pressure change of a cup main body is suppressed and the content can be taken out smoothly.

Further, in the cup container with a lid according to the present invention, the cutting edge portion extends from the peripheral edge of the outlet portion toward the pressing direction of the rotating plate, and is connected at the tip portions separated from the outlet portion. It is preferable to have a plurality of cutting edge beam portions.
In this invention, the sealing member broken by the cutting blade portion sticks to the cutting blade portion, the opening portion is prevented from being blocked by the broken sealing member, and the contents can be taken out smoothly.

  According to the cup container with a lid according to the present invention, when the contents are taken out, it becomes difficult for the contents to be scattered and leaked from the part other than the outlet part, and the contents touch the contents when the pressing part is pressed. It becomes difficult and hygienic.

  Hereinafter, one embodiment of a cup container with a lid by the present invention is described based on a drawing. In each drawing used in the following description, the scale is appropriately changed to make each member a recognizable size.

The cup container 1 with a lid according to the present invention, as shown in FIGS. 1 to 3, is filled with, for example, a beverage or the like and distributed by the user (consumer) directly from the cup container. Can drink.
As shown in FIGS. 2 and 3, the cup container 1 with a lid includes a cup body 11, a lid body 12, and an outer lid 13. In addition, illustration of the outer cover 13 is abbreviate | omitted in FIG.

The cup body 11 has a substantially bottomed cylindrical shape extending along the axis L, and opens toward the upper portion by the open end 21. Further, as shown in FIG. 2, the cup body 11 includes a tapered body portion 22 that decreases in diameter as it goes downward, and a bottom portion 23 that is connected to the lower end portion of the tapered body portion 22.
As shown in FIGS. 2 and 3, a flange portion 24 that is bent outward in the radial direction of the cup body 11 is formed at the upper end portion of the tapered body portion 22.

A seal member 25 that seals the open end 21 is attached to the upper surface of the flange portion 24.
The seal member 25 is made of, for example, a barrier sheet material such as an aluminum vapor-deposited sheet, and a heat welding layer is formed on the lower surface. The seal member 25 is thermally welded to the upper surface of the flange portion 24 after the cup body 11 is filled with a beverage, and seals the beverage in the cup body 11 so as not to leak to the outside. In addition, when a barrier sheet material is used as the sealing member 25, it is possible to prevent air or the like from entering the cup body 11 and prevent the beverage from being deteriorated.

  The lid 12 is attached to the upper part of the cup body 11 with the sealing member 25 attached to the open end 21 of the cup body 11. The lid body 12 includes a side wall portion 31 having a cylindrical shape with the axis M as a center, a top surface portion 32 connected to the inner peripheral surface of the side wall portion 31, and a cutting blade member 33 that breaks the seal member 25. ing.

An annular flat surface portion 34 and a mounting cylinder portion 35 are provided at the lower end of the side wall portion 31.
The annular flat surface portion 34 is connected to the outer peripheral surface of the side wall portion 31 and extends outward in the radial direction of the lid body 12.
The mounting cylinder portion 35 is connected to the side wall portion 31 via the annular flat surface portion 34, and has an inner diameter and an outer diameter that are larger than the side wall portion 31. Further, an engagement convex portion 35 </ b> A that protrudes inward in the radial direction of the lid body 12 is formed on the inner peripheral surface of the mounting cylinder portion 35.

  The inner diameter of the protruding portion of the engaging convex portion 35 </ b> A is smaller than the outer diameter of the flange portion 24. Therefore, when the mounting cylinder part 35 is put on the flange part 24, the engaging convex part 35 </ b> A engages with the lower surface side of the flange part 24, and the seal projection part suspended from the annular flat surface part 34 or the lower surface of the annular flat surface part 34. Is brought into contact with the upper surface of the flange portion 24 via a seal member 25, and the lid body 12 is fixed to the cup body 11. Further, when the lid 12 is attached to the cup body 11, the axis L of the cup body 11 and the axis M of the lid 12 coincide.

The thickness of the side wall 31 decreases as it goes upward.
Further, as shown in FIGS. 1 and 3, the side wall portion 31 is connected to a standing cutting blade member 33 and maintains a standing state in which the tip portion of the cutting blade member 33 faces upward from the top surface portion 32. A bridge portion (standing state holding portion) 36 is formed.

  As shown in FIGS. 2 and 3, the top surface portion 32 has a central portion in the radial direction of the lid body 12 slightly protruding upward as compared with the peripheral portion. Thus, a space is formed in advance between the top surface portion 32 and the seal member 25 by projecting the central portion of the top surface portion 32 upward. For this reason, when the cup body 11 is filled with a content liquid such as a hot beverage, the seal member 25 swells upward due to the internal pressure of the cup body 11, but the top surface portion 32 is deformed by the seal member 25 swelled upward. The seal member 25 is prevented from coming into contact with the cutting blade member 33 and being torn.

As shown in FIGS. 1 to 3, the top surface portion 32 is formed with an opening 37 for allowing the cutting blade member 33 to rotate.
As shown in FIG. 1, the opening 37 is a belt-like shape that substantially crosses the top surface portion 32 in the diametrical direction, and the central portion in the extending direction is a wide portion that protrudes in one direction in the width direction. It is substantially T-shaped in plan view. The opening 37 has one end in the extending direction in contact with the outer peripheral edge of the top surface portion 32 and is formed to be slightly larger than the cutting blade member 33. Thereby, the sealing member 25 is broken by the cutting blade member 33 without being caught on the top surface portion 32.

Further, as shown in FIG. 1 and FIG. 3, a rising portion 32 </ b> A that protrudes upward is formed at the edge portion of the top surface portion 32 that is close to the other end in the extending direction of the opening 37.
A bridge portion (standing state holding portion) 38 that is connected to the standing cutting blade member 33 and holds the standing state of the cutting blade member 33 is formed on the upright portion 32A.

Further, as shown in FIGS. 1 and 2, an anti-rotation protrusion that holds the closed state in which the cutting blade member 33 closes the opening 37 is formed at the edge of the top surface 32 close to the wide portion of the opening 37. Portions (closed state holding portions) 39A and 39B are formed.
Each of the rotation preventing convex portions 39A and 39B is formed to protrude from the edge portion of the top surface portion 32 adjacent to the wide portion of the opening portion 37 toward the inside of the opening portion 37. The rotation preventing convex portion 39 </ b> A is formed on the lower surface side of the top surface portion 32, and the rotation preventing convex portion 39 </ b> B is formed on the upper surface side of the top surface portion 32. For this reason, a gap is formed between the rotation preventing convex portions 39A and 39B. Note that the inward protrusion amount of the opening 37 in the rotation prevention convex portion 39B is smaller than the inward protrusion amount of the opening 37 in the rotation prevention convex portion 39A.

As shown in FIGS. 1 to 3, the cutting blade member 33 includes a rotating plate 41, a cutting blade portion 42, and a sub cutting blade portion 43.
As shown in FIG. 1, the rotating plate 41 is a push-down portion 44 that is substantially strip-shaped and has a central portion in the extending direction protruding in one direction in the width direction, like the opening portion 37. It is substantially T-shaped in plan view. As shown in FIGS. 1 and 2, the rotating plate 41 is rotatably connected to the top surface portion 32 via a hinge portion 45 formed at the edge of the top surface portion 32 in the opening 37. . Thereby, the rotation plate 41 can be rotated with the one end side separated from the pressing portion 44 in the width direction as a rotation axis.

The tip portion of the pressing portion 44 that is separated from the rotation shaft can be engaged with the rotation prevention convex portions 39A and 39B when the cutting blade member 33 is rotated around the hinge portion 45.
In addition, as shown in FIGS. 1 to 3, the rotating plate 41 is formed so that a mouthpiece (outlet portion) 46 is separated from the pressing portion 44. As shown in FIG. 1, the mouthpiece portion 46 has a substantially rectangular shape in plan view, and is formed at one end portion close to the outer peripheral edge of the top surface portion 32 in the extending direction of the rotating plate 41.

As shown in FIGS. 2 to 4, the cutting edge portion 42 is formed to protrude downward on the lower surface of the rotating plate 41, and has four cutting edge beam portions 47.
The cutting blade portions 47 are formed so as to extend from the respective corners of the mouthpiece portion 46 toward the lower side of the rotating plate 41, and are connected to each other at the distal ends that are separated from the rotating plate 41. . For this reason, a substantially triangular cutting edge portion 48 is formed in a region surrounded by the edge portion of the opening 37 and the two cutting edge beam portions 47 adjacent to each other. Therefore, four cutting edge portions 48 are formed in the cutting edge portion 42. Here, the distance between the tip of the cutting edge part 42 and the mouth part 46 is longer than the distance between the seal member 25 and the mouth part 46.

  Similarly to the cutting edge portion 42, the auxiliary cutting edge portion 43 is formed on the lower surface of the rotating plate 41 so as to protrude downward from the other end portion in the extending direction of the rotating plate 41 (on the rotating plate 41. Each of the formed air port portions is extended downward from the rotating plate 41), and has four sub cutting edge beam portions 49. The amount of protrusion of the auxiliary cutting edge 43 is equivalent to that of the cutting edge 42.

As shown in FIGS. 2 and 3, the outer lid 13 is attached so as to cover the lid body 12 on the outer side of the lid body 12.
The outer lid 13 includes a cylindrical portion 51 that has a cylindrical shape centered on the axis N, and a top plate portion 52 that is disposed at the upper end of the cylindrical portion 51 and covers the upper end opening of the cylindrical portion 51.
The cylindrical portion 51 can be attached to the lid body 12. The outer lid 13 is attached to the lid body 12 by fitting the inner circumferential surface of the cylindrical portion 51 with the outer circumferential surface of the mounting cylinder portion 35 of the lid body. Further, when the outer lid 13 is attached to the lid body 12, the axis M of the lid body 12 and the axis N of the outer lid 13 coincide.

Next, the opening method of the cup container 1 with a lid | cover of the above structures is demonstrated.
First, the outer lid 13 is removed. Then, the pressing portion 44 is pushed downward to break the bridge portion 36 connecting the rotating plate 41 and the side wall portion 31 and the bridge portion 38 connecting the rotating plate 41 and the upright portion 32A. (See FIG. 5 (a)). As a result, the cutting blade member 33 is released from the standing state and can be rotated around the rotation axis of the hinge portion 45, and the tips of the cutting blade portion 42 and the auxiliary cutting blade portion 43 abut against the seal member 25. In this state, when the pressing portion 44 is further pressed down, the cutting blade portion 42 breaks the seal member 25 (see FIG. 5B). Further, the auxiliary cutting edge portion 43 breaks the seal member 25 similarly to the cutting edge portion 42 and forms an opening at a position different from the opening formed in the sealing member 25 by the cutting edge portion 42. And the rotation board 41 closes the opening part 37, and will be in a closed state.
At this time, the tip portion of the pressing portion 44 abuts against the rotation preventing convex portion 39A, thereby preventing the rotation plate 41 from rotating below the top surface portion 32. Moreover, the closed state of the cutting blade member 33 is hold | maintained because the front-end | tip part of the pressing part 44 engages with rotation prevention convex part 39A, 39B.

Here, since the pressing part 44 is formed away from the mouth part 46, a finger or the like does not touch the mouth part 46 when the pressing part 44 is pressed. Further, since the cutting blade member 33 is held in a closed state and does not rotate downward from the top surface portion 32, a finger or the like does not enter the cup body 11 by pressing the pressing portion 44.
And since the cutting edge part 42 has the four cutting edge beam parts 47, and the some cutting edge part 48 which each faces a different direction is formed, the sealing member fractured | ruptured by the cutting edge part 42 It is suppressed that 25 sticks to all of the cutting edge part 48, and the drinking part 46 becomes difficult to block.

As described above, the seal member 25 is opened. Thereby, the user (consumer) can drink the beverage in the cup body 11.
Here, since the mouth part 46 is formed in the vicinity of the side wall part 31, the distance between the mouth of the user (consumer) and the mouth part 46 becomes short, and it becomes easy to drink beverages. Moreover, although a drink etc. are taken out through the opening formed in the sealing member 25 by the cutting blade part 42, if the opening formed by the cutting blade part 42 is obstruct | occluded by the distribution | circulation of a drink, the drink in the cup main body 11, etc. Due to the change in the internal pressure accompanying the decrease in the amount of the beverage, it becomes difficult for the beverage or the like to flow through the opening. However, since the other opening by the sub-cutting-edge part 43 is formed in the sealing member 25, the internal pressure change of the cup main body 11 is suppressed even if the opening is closed with a beverage or the like.

  According to the lid-equipped cup container 1 in the present embodiment, the cutting blade member 33 is closed and the seal member 25 is opened, so that beverages and the like are less likely to splash outside from the portion other than the mouthpiece portion 46 and pressed. Since the portion 44 and the mouthpiece portion 46 are separated from each other, it is difficult to touch the contents with a finger or the like when the seal member 25 is opened, which is hygienic.

  Further, since the standing state of the cutting blade member 33 is held by the bridge portions 36 and 38, the sealing member 25 can be prevented from being broken by the cutting blade member 33 due to vibration during distribution. And since the closed state of the cutting blade member 33 is hold | maintained by rotation prevention convex part 39A, 39B, when drinking a drink etc. after opening, the cutting blade member 33 is prevented from rotating and leaking a drink. At the same time, it is possible to more reliably prevent the rotation plate 41 from rotating below the top surface portion 32 and the finger or the like entering the cup body 11 when the pressing portion 44 is pressed.

  Furthermore, openings are formed at a plurality of locations on the seal member 25 by the cutting blade portion 42 and the auxiliary cutting blade portion 43, and even if the opening formed by the cutting blade portion 42 is closed with a beverage, the internal pressure change of the cup body 11 is suppressed. Therefore, beverages can be taken out smoothly. In addition, by forming a plurality of cutting edge portions 48 facing in different directions on the cutting edge portion 42, the sealing member 25 broken by the cutting edge portion 42 is difficult to stick to all of the cutting edge portions 48. Therefore, beverages can be taken out smoothly.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, the structure of the cutting edge portion is not limited to a structure in which four cutting edge beam portions are connected. For example, as shown in FIG. 6 (a), the cutting blade portion has a substantially triangular shape in a side view protruding downward. Each of the cutting blade plate portions 100 may be a cutting blade portion 101 having a structure in which the cutting blade plate portions 100 are connected so as to form a substantially cruciform shape when viewed from above, and as shown in FIG. 6 may be a cutting blade portion 103 having a structure in which three cutting blade plate portions 102 are connected so as to form a substantially U-shape in a plan view. As shown in FIG. The cutting blade portion 105 may have a frame structure in which the four cutting blade plate portions 104 are connected so as to form a substantially rectangular shape in plan view along the edge of 46, or may have another structure. And the structure of the sub cutting edge part is not restricted to the structure which connected the four sub cutting edge beam parts similarly to the cutting edge part, For example, other structures, such as a solid structure, may be sufficient.
The shape of the mouthpiece is not limited to a substantially rectangular shape in plan view, and may be other shapes such as a circular shape in plan view and a polygonal shape.
And although the cutting blade part is formed in the edge part of a mouth part, it may be spaced apart from the edge part of a mouth part.

In addition, the standing state holding portion is formed by a bridge portion connected to the rotating plate. However, if the standing state of the cutting blade member can be held, the standing state projecting portion protrudes inward in the radial direction of the lid body and is in the standing state. Other structures, such as a locking projection for locking the cutting blade member, may or may not be provided.
Similarly, the closed state holding portion is formed by a rotation prevention convex portion to which the pressing portion of the rotation plate is locked, but may have another structure as long as the closed state of the cutting blade member can be held. It is not necessary to provide it.
The cutting blade member has a cutting edge portion and a secondary cutting edge portion. However, the cutting blade member only needs to have at least a cutting edge portion, and has a secondary cutting edge portion as long as the contents can be taken out smoothly. It may not be necessary, and it may have two or more sub cutting edges.
Furthermore, the sealing member is not limited to one made of a barrier sheet material such as an aluminum vapor-deposited sheet, and may be appropriately changed according to the contents in the cup body.

  According to this invention, when opening with a cutting blade member, while being hygienic without touching the contents in the cup body with fingers etc., the lid-equipped cup container that can prevent the contents from scattering to the outside, Industrial applicability is recognized.

It is a cup container with a lid in an embodiment of the present invention, is an axial sectional view showing the closed state of the cutting blade member, It is AA arrow sectional drawing which shows the standing state of the cutting blade member in FIG. It is BB arrow sectional drawing of FIG. It is a back surface perspective view which shows the cutting blade part of FIG. It is explanatory drawing explaining the opening operation of a sealing member. It is a perspective view which shows the other cutting blade part which can apply this invention.
