Description

  The present invention relates to a cup container with a lid.

  Conventionally, for example, as shown in Patent Document 1 below, the contents are accommodated and the upper end opening is sealed with a sealing material, and the upper end of the cup body is attached to the sealing material. There is known a lid-equipped cup container provided with a lid that covers the upper side of the lid.

Japanese Patent No. 3607002

  However, in the conventional cup container with a lid, there is room for improvement in fitting the lid body easily and reliably to the cup body while preventing the structure from becoming complicated.

  The present invention has been made in view of such circumstances, and provides a cup container with a lid that can easily and surely fit a lid body to a cup body while preventing a complicated structure. For the purpose.

  In order to solve the above-described problems and achieve such an object, a cup container with a lid according to the present invention is mounted on a cup body in which contents are stored, and an upper end portion of the cup body, and the cup A lid-equipped cup container having a main body plate disposed above the main body, wherein the lid body extends downward from an outer peripheral edge of the main body plate, and a lower end of the peripheral wall A lid flange portion projecting outward from the cup radial direction, and extending downward from the outer peripheral edge of the lid flange portion to the inner circumferential surface from the upper end of the cup body to the outer side in the cup radial direction A mounting cylinder formed with a support projection for supporting the lower surface of the protruding cup flange portion, and the lid flange portion is arranged at a position corresponding to the support projection along the circumferential direction of the cup. An extended slit and And a rib disposed on the outside of the flop radially, characterized in that is provided.

According to this invention, the lid flange portion is formed with slits and ribs corresponding to the circumferential direction of the cup, so that the entire lid flange portion is moved upward with the lid placed on the cup flange portion of the cup body. It is possible to stabilize the mounting operation by pushing in.
For example, if there is a slit but there is no rib, pressing the entire lid flange part from above with the lid placed on the cup flange part of the cup body will correspond to the slit in the cup circumferential direction of the mounting cylinder Since the part to be stretched is more easily elastically deformed so as to spread outward than the other part in the cup radial direction, the support projection of the mounting cylinder is the cup of the cup body when the mounting cylinder is restored and displaced by releasing the lid. In some cases, the lid cannot be locked to the lower surface of the flange, and the lid cannot be attached to the cup body.
However, in the present invention, by forming the rib corresponding to the slit, the portion of the mounting cylinder corresponding to the rib in the cup circumferential direction is lower than the other portion in the cup axial direction corresponding to the height of the rib. The support protrusion is pushed into the lower surface of the cup flange portion. Therefore, even if the pushing of the lid is released and the mounting cylinder is restored and displaced, the support protrusion of the mounting cylinder can be locked to the lower surface of the cup flange portion of the cup body, and the mounting operation of the lid on the cup body is stabilized. Thus, by providing a slit with a slit, a rib, and a support protrusion in the lid, it is possible to provide excellent fitting properties such that it is easy to attach to the cup body and is difficult to come off once fitted.
In addition, since it is possible to cope with a slight change in the structure of the lid, there is no need to change the existing equipment in order to fit the lid easily and securely to the cup body. Is possible.

The cup container with a lid according to the present invention accommodates the contents and is attached to the upper end of the cup body, the upper end opening of which is sealed with a sealing material, and above the sealing material. A lid-equipped cup container having a body plate disposed therein, and connected to the body plate via a first rotating portion in a through-hole formed in the body plate, and A cutting blade portion extending forward from the first rotating portion, and connected to both sides of the cup circumferential direction in the cutting blade portion, and separately connected to the main body plate via each second rotating portion, And a pair of left and right operation portions extending rearward from the second rotation portion, and the cutting blade portion, the operation portion, the first rotation portion, and the second rotation portion are arranged on the main body plate. The first rotating part and the second rotating part are formed in a plan view of the main body plate. It may be characterized in that it is arranged on the same straight line.
Therefore, when the operation portion is pulled up, the cutting blade portion and the operation portion are integrally rotated around the first and second rotation portions so that the front end portion of the cutting blade portion is lowered, so that the cutting blade portion is sealed. The seal material is broken by being pressed against the material.
Thus, it becomes possible to break the sealing material and open the cup body only by pulling up the operation portion, and it is possible to provide excellent opening operability. In addition, since the left and right operation parts are arranged, a plurality of fingers can be applied to the operation part at the time of opening, and a large force can be stably applied from the cutting edge part to the sealing material.
Furthermore, since the first and second rotating parts are arranged on the same straight line in a plan view of the main body plate, the first and second rotating parts are prevented from being twisted when the operating part is pulled up. It becomes possible, and the outstanding opening operativity can be exhibited stably.
Moreover, since the cutting edge part, the operation part, the 1st rotation part, and the 2nd rotation part are integrally formed with the main body board, the number of parts can be suppressed and the complication of a structure can be prevented.
Here, the cutting blade portion is disposed at the front end portion thereof, and opens at the front end portion thereof, and protrudes downward. The cutting blade portion is disposed rearward of the opening blade portion and protrudes downward. A leading blade that comes into contact with the sealing material before the opening blade when the portion is integrally rotated around the first and second rotating portions may be disposed.
In this case, when the cutting blade portion and the operation portion are integrally rotated around the first and second rotating portions, the leading blade comes into contact with the sealing material prior to the opening blade, so that the leading blade precedes the opening blade. It becomes possible to break the sealing material with the blade. Therefore, when the internal pressure of the cup body is in a pressurized state, the sealing material is first broken by the leading blade located at the rear to release the internal pressure of the cup body, and then the sealing material is broken by the opening blade located at the front can do. Thereby, even if the internal pressure of the cup body is in a pressurized state, it is possible to prevent the contents from being scattered outside when the cup body is opened.
The cutting blade portion may be provided with a pair of surrounding walls extending rearward from both sides in the left-right direction of the opening blade and surrounding the leading blade from both sides in the left-right direction.
In this case, since the leading blade is surrounded by the opening blade and the surrounding wall, when the sealing material is broken with the leading blade prior to the opening blade, even if the content pops out from the broken portion, the popped out content is not It is possible to suppress scattering to the outside by colliding with the opening blade and the surrounding wall.
Note that the lower end edge of the surrounding wall may be sharpened downward and the sealing material may be broken together with the opening blade.

  According to the present invention, the lid can be easily and reliably fitted to the cup body while preventing the structure from becoming complicated.

It is the A section enlarged view of the cup container with a lid shown in FIG. It is a top view of the cover body of the cup container with a lid shown in FIG. It is a bottom view of the cover body of the cup container with a lid shown in FIG. It is the front view which looked at the opening blade of the cover body of the cup container with a lid shown in FIG. 1 from the front. It is a longitudinal section of a cup container with a lid shown as an embodiment concerning the present invention. It is a top view of the lid body of the cup container with a lid shown in FIG. It is a bottom view of the lid body of the cup container with a lid shown in FIG.

Hereinafter, a cup container 1 with a lid according to the present invention will be described with reference to the drawings.
As shown in FIG. 1, the cup container 1 with a lid according to the present embodiment includes a cup body 11 in which contents are stored, a lid body 12 attached to the cup body 11, and an overcap 13 that covers the lid body 12. And.
The cup body 11 is formed in a bottomed cylindrical shape, and the lid body 12 and the overcap 13 are each formed in a topped cylindrical shape. The central axes of the cup body 11, the lid body 12, and the overcap 13 are arranged coaxially with the common axis. Hereinafter, this common axis is referred to as the container axis O, the bottom 11a side of the cup body 11 along the container axis O direction is referred to as the lower side, the opposite side is referred to as the upper side, and the direction along the container axis O is referred to as the up-down direction. Further, in a plan view viewed from the container axis O direction, a direction orthogonal to the container axis O is referred to as a cup radial direction, and a direction around the container axis O is referred to as a cup circumferential direction.

At the upper end of the cup body 11, a first flange portion 11b that protrudes outward in the cup radial direction and continuously extends over the entire circumference is formed. The upper end opening 11e of the cup body 11 is sealed by fixing the sealing material 14 to the first flange portion (cup flange portion) 11b.
Note that a plurality of support protrusions 11 d that protrude toward the inner side in the cup radial direction are formed in the lower portion of the cup body 11 at intervals in the cup circumferential direction. The support protrusion 11d supports the outer peripheral edge portion of the bottom portion 11a of the other cup body 11 in a state where the other cup body 11 is inserted into the cup body 11 from the bottom portion 11a side. Thereby, the close_contact | adherence of both the cup main bodies 11 can be prevented, and the cup main body 11 stacked in multiple numbers can be taken out easily separately.

And in this embodiment, as FIG. 2 shows, the 1st flange part 11b is an inner side of a cup radial direction so that the 1st flange part 11b may become horizontal when the internal pressure of the cup main body 11 rises. As it goes from the outside to the outside, it gradually extends downward.
In addition, a protruding portion 11c is formed at the upper end portion of the inner peripheral surface of the cup body 11 so as to protrude toward the inner side in the cup radial direction and whose upper surface is continuous with the upper surface of the first flange portion 11b. The overhanging portion 11c extends continuously over the entire circumference in the cup circumferential direction. The lower end of the overhanging portion 11c is connected to the inner peripheral surface of the cup body 11 without a step. The radius of curvature formed by the longitudinal section of the cup body 11 at this portion is, for example, about 0.2 mm so that the inner end in the cup radial direction at the upper end of the overhanging portion 11c is pointed inward in the cup radial direction. It is as small as possible.

And the sealing material 14 is being integrally fixed over the whole area of each upper surface of the 1st flange part 11b and the overhang | projection part 11c.
In this way, by fixing the sealing material 14 not only to the upper surface of the first flange portion 11b but also to the upper surface of the overhanging portion 11c, the fixing area of the sealing material 14 to the cup body 11 is increased in the cup radial direction. Thus, when the internal pressure of the cup body 11 is increased, the sealing material 14 can be prevented from bulging upward and deforming.

The lid 12 is attached to the upper end of the cup body 11.
The lid 12 protrudes from the lower end of the peripheral wall 22 toward the outer side in the cup radial direction, the main body plate 21 disposed above the seal material 14, the peripheral wall 22 extending downward from the outer peripheral edge of the main body plate 21. And a second flange portion (lid flange portion) 23 extending continuously over the entire circumference, and extending downward from the outer end of the second flange portion 23 in the cup radial direction, and the first flange of the cup body 11 And a mounting cylinder 24 externally fitted to the portion 11b.

  The mounting cylinder 24 is formed with a support protrusion 24a that protrudes inward in the cup radial direction and supports the lower surface of the first flange portion 11b. A plurality of support protrusions 24a are formed on the mounting cylinder 24 at intervals in the cup circumferential direction. In the illustrated example, eleven support protrusions 24a are arranged at equal intervals in the cup circumferential direction. In other words, the plurality of support protrusions 24 a are arranged at positions shifted in the cup circumferential direction with respect to positions facing each other across the container axis O in the cup radial direction on the inner circumferential surface of the mounting cylinder 24. Thereby, when the support protrusion 24a gets over the first flange portion 11b and the lid body 12 is attached to the upper end portion of the cup body 11, the pressing force applied to the cup body 11 is applied to the lid body 12. It can suppress becoming high too much.

And in this embodiment, as FIG.3 and FIG.4 shows, it connects with the main body board 21 via the 1st rotation part 31 in the through-hole 25 formed in the main body board 21, and is 1st. The cutting blade portion 32 extending forward from the rotating portion 31 is connected to both sides of the cutting blade portion 32 in the circumferential direction of the cup, and connected to the main body plate 21 via the second rotating portions 33. In addition, a pair of left and right operation units 34 extending rearward from the second rotation unit 33 is disposed.
The through-hole 25 includes a pair of left and right side portions 25a extending in the front-rear direction and a front portion 25b that connects the front ends of the side portions 25a and opens rearward in a plan view of the main body plate 21. It is U-shaped.
Further, the first and second rotating parts 31 and 33 are hinges formed thinner than the main body plate 21, the cutting edge part 32, and the operation part 34.

The cutting edge portion 32 is disposed in the front portion 25 b of the through hole 25, and the operation portion 34 is disposed in the side portion 25 a of the through hole 25.
The cutting edge portion 32 has a triangular shape in which the width in the left-right direction gradually decreases from the rear toward the front in a plan view of the main body plate 21. In addition, the both ends of the left-right direction in the cutting blade part 32 are connected with the inner periphery of the through-hole 25 via the bridge | bridging 21b which can be fractured.
Here, one of the three side portions constituting the triangular shape constitutes a rear end portion 32a of the cutting blade portion 32 extending in the left-right direction. Further, one of the three apexes constituting the triangular shape constitutes the front end portion of the cutting edge portion 32 located at the center portion in the left-right direction. An opening blade 35 protruding downward is disposed at the front end portion of the cutting blade portion 32. As shown in FIG. 5, the opening blade 35 is a wall portion extending in the left-right direction, and the front surface thereof is close to the front end of the inner peripheral edge of the through hole 25. A plurality of cutting blades 35a pointed downward are formed in the lower end portion of the opening blade 35 in a line in the left-right direction.

  As shown in FIGS. 1 and 4, the cutting blade portion 32 is disposed behind the unsealing blade 35, is sharpened downward, and the cutting blade portion 32 and the operation portion 34 are rotated first and second. A leading blade 36 that comes into contact with the sealing material 14 before the opening blade 35 when disposed integrally around the portions 31 and 33 is disposed. The leading blade 36 has a width in the left-right direction that is smaller than the opening blade 35 so that the breaking opening formed in the sealing material 14 is small, and is adjacent to the opening blade 35. Further, the leading blade 36 is disposed in the center portion in the left-right direction of the cutting blade portion 32. The positions along the vertical direction of the lower edge of each of the leading blade 36 and the opening blade 35 are equal to each other. The positions along the vertical direction of the lower edge of each of the leading blade 36 and the opening blade 35 may be different from each other.

The cutting blade portion 32 is provided with a pair of surrounding walls 37 that extend backward from both sides in the left-right direction of the opening blade 35 and surround the leading blade 36 from both sides in the left-right direction. The surrounding wall 37 is connected to the opening blade 35, and the leading blade 36 is covered with the opening blade 35 on the front side, and the pair of surrounding walls 37 covers both sides in the left-right direction. The lower end edge of the surrounding wall 37 is located above the lower end edges of the leading blade 36 and the opening blade 35. The lower end edge of the surrounding wall 37 is pointed downward and formed so that the sealing material 14 can be broken. The amount of protrusion toward the lower side of the surrounding wall 37 gradually increases from the rear toward the front.
Note that a gap may be provided between the surrounding wall 37 and the opening blade 35, and the lower end edge of the surrounding wall 37 may not be sharpened downward. Further, the amount of protrusion toward the lower side of the surrounding wall 37 may be equal over the entire length in the front-rear direction, or may be gradually increased from the front toward the rear.

In the rear end portion 32a of the cutting blade portion 32, the first rotating portion 31 is connected to the center portion in the left-right direction, and the operation portion 34 protruding backward is connected to both end portions in the left-right direction (cup circumferential direction). ing.
The operation part 34 protrudes from the cutting edge part 32 not only to the rear but also to the outside in the left-right direction, and the second rotating part 33 is connected to the front end part of the protruding part. The first rotating part 31 and the second rotating part 33 are arranged on the same straight line in a plan view of the main body plate 21.
A reinforcing rib 34b that protrudes downward and extends rearward is formed at a connection portion with the second rotation portion 33 on the lower surface of the operation portion 34. The reinforcing ribs 34b can suppress the deformation of the operation unit 34 when the operation unit 34 is pulled up.

The connecting portion between the rear edge 34a and the inner edge 34c in the left-right direction in the operation portion 34 is a chamfer that gradually extends from the outer side in the left-right direction toward the inner side in the plan view of the main body plate 21 from the rear to the front. A portion 34d is formed.
The operation unit 34 is formed in a dome shape that bulges upward and has a rear half removed and opened rearward.
Here, since the operation unit 34 is not only formed in the dome shape as described above, but also the chamfered portion 34d is formed in the operation unit 34, it is easy to insert a finger below the operation unit 34.
The operation unit 34 bulges upward from the main body plate 21. Further, the upper surface of the cutting edge portion 32 is flush with the upper surface of the main body plate 21.
As shown in FIGS. 3 and 4, the rear end edge 34 a of the operation unit 34 is formed in a curved shape that is gradually recessed forward as it goes from the outer side to the inner side in the left-right direction. The rear end edge 34a of the operation portion 34 is separated forward from the rear end of the side portion 25a of the through hole 25, and the rear end of the side portion 25a of the through hole 25 and the rear end edge 34a of the operation portion 34 are separated. A finger can be inserted in a portion located between them.
The cutting blade part 32, the operation part 34, the first rotating part 31, and the second rotating part 33 are formed integrally with the main body plate 21.
Note that a slit 31 a extending in the left-right direction is formed at the center in the left-right direction of the first rotating portion 31.

As shown in FIGS. 1 and 4, the main body plate 21 is formed with a puncture portion 21 a that protrudes downward. When the internal pressure of the cup main body 11 rises excessively and the sealing material 14 is greatly bulged and deformed upward, the puncture portion 21a abuts against the sealing material 14 and breaks the sealing material 14 to reduce the internal pressure of the cup main body 11. Open.
The puncture portion 21a is disposed on the peninsula portion 21e of the main body plate 21 surrounded by the front portion 25b and the pair of side portions 25a in the through hole 25. In the illustrated example, the puncture portion 21a is disposed at the center of the main body plate 21, and is formed in a sharp shape that gradually protrudes downward from the front toward the rear. In addition, the lower end edge of the puncture part 21a is located above the lower end edge of each of the leading blade 36 and the opening blade 35, and is located below the lower end edge of the surrounding wall 37. The peninsula portion 21e of the main body plate 21 is formed in a rectangular plate shape that is long in the front-rear direction.
Here, a first projecting rib 21c and a second projecting rib 21d projecting downward are formed on the lower surface of the peninsula portion 21e. Since the bending rigidity of the peninsula portion 21e is increased by the first and second projecting ribs 21c and 21d, the peninsula portion 21e is deformed when the sealing material 14 is greatly bulged upward and pressed against the puncture portion 21a. It becomes possible to suppress bending upward, and the sealing material 14 can be reliably broken by the puncture portion 21a.
In the illustrated example, the first protruding rib 21c surrounds the puncture portion 21a from the outside in the cup radial direction. Moreover, the 1st protrusion rib 21c is exhibiting C shape opened toward the front by the planar view of the main body board 21. As shown in FIG.
The second projecting rib 21d extends over the entire length of the peninsula portion 21e in the front-rear direction, and a plurality of second projecting ribs 21d are formed with an interval in the left-right direction.

  As shown in FIGS. 1 and 3, the front end of the inner peripheral edge of the through hole 25 is flush with the inner peripheral surface of the peripheral wall 22. Moreover, the part adjacent to the front part 25b of the through-hole 25 among the outer periphery parts of the main-body board 21 is extended toward upper direction gradually as it goes inside from the outer side of a cup circumferential direction. In connection with this, the part adjacent to the front part 25b of the through-hole 25 is also extended toward the upper direction gradually toward the inner side from the outer side of a cup circumferential direction also in the surrounding wall 22.

Further, in this embodiment, when the overcap 13 is attached to the lid body 12, the top wall portion of the overcap 13 pushes down the operation portion 34, thereby lowering the lower edge of each of the opening blade 35 and the leading blade 36. , Raised and positioned at the expected position along the vertical direction. Thereby, it is possible to prevent the lower end edges of the unsealing blade 35 and the leading blade 36 from coming into contact with the sealing material 14.
In addition, in the state where the overcap 13 is attached to the lid body 12, the top wall portion of the overcap 13 is in contact with or close to the operation portion 34, so that the lower edge of each of the opening blade 35 and the leading blade 36 is When the cutting blade portion 32 and the operation portion 34 are about to rotate about the first and second rotation portions 31 and 33 so as to move downward, the operation portion 34 is placed on the top wall portion of the overcap 13. It will be locked and this rotation can be suppressed.
As described above, the lower edge of each of the opening blade 35 and the leading blade 36 is attached to the sealing material 14 when the lid body 12 with the overcap 13 attached is attached to the cup body 11 and when the cup container 1 with lid is distributed. It is possible to reliably prevent contact.

As described above, according to the cup container 1 with a lid according to the present embodiment, the cutting blade portion 32 and the operation portion 34 are integrated so that when the operation portion 34 is pulled up, the front end portion of the cutting blade portion 32 is lowered. By rotating around the first and second rotating portions 31 and 33, the opening blade 35 is pressed against the sealing material 14 and the sealing material 14 is broken.
Thus, it becomes possible to break the sealing material 14 and open the cup body 11 only by pulling up the operation portion 34, and it is possible to provide excellent opening operability. In addition, since a pair of left and right operation portions 34 are provided, it is possible to place a plurality of fingers on the operation portion 34 when opening, and a large force can be stably applied from the cutting blade portion 32 to the sealing material 14. Can do.
Further, since the first and second rotating parts 31 and 33 are arranged on the same straight line in a plan view of the main body plate 21, the first and second rotating parts 31 are raised when the operation part 34 is pulled up. , 33 can be prevented from being twisted, and excellent opening operability can be stably exhibited.
Moreover, since the cutting blade part 32, the operation part 34, the 1st rotation part 31, and the 2nd rotation part 33 are integrally formed with the main body board 21, the number of parts is suppressed and the complexity of a structure is prevented. be able to.

  Furthermore, when the cutting blade portion 32 and the operation portion 34 are integrally rotated around the first and second rotating portions 31 and 33, the leading blade 36 comes into contact with the sealing material 14 before the opening blade 35. The sealing material 14 can be broken with the leading blade 36 prior to the opening blade 35. Therefore, when the internal pressure of the cup body 11 is in a pressurized state, the sealing material 14 is first broken by the leading blade 36 located at the rear to release the internal pressure of the cup body 11, and then the opening blade 35 located at the front. Thus, the sealing material 14 can be broken. Thereby, even if the internal pressure of the cup main body 11 is in a pressurized state, it is possible to prevent the contents from being scattered outside when the cup main body 11 is opened.

Further, since the leading blade 36 is surrounded by the opening blade 35 and the surrounding wall 37, even if the contents pop out from the broken portion when the sealing material 14 is broken by the leading blade 36 prior to the opening blade 35, It can suppress that the content which protruded collides with the opening blade 35 and the surrounding wall 37, and is scattered outside.
Further, since the lower end edge of the surrounding wall 37 is pointed downward, it is opened when the cutting blade part 32 and the operation part 34 are rotated together around the first and second rotating parts 31 and 33. The sealing material 14 can be broken by both the blade 35 and the surrounding wall 37, and a wide opening can be formed in the sealing material 14.
Further, since the slit 31a is formed in the first rotating part 31, it is possible to suppress the restoring displacement of the cutting blade part 32 and the operating part 34 after the operating part 34 is pulled up and the sealing material 14 is broken. it can.

  Next, the lidded cup container 100 according to the embodiment of the present invention will be described. The lid-equipped cup container 100 according to this embodiment has the same basic configuration as the lid-equipped cup container 1 described above, and is obtained by adding another element to the lid-equipped cup container 1 described above. Therefore, in FIGS. 6 to 8, the same components as those in FIGS. 1 to 5 are denoted by the same reference numerals, and the description thereof is omitted.

As shown in FIGS. 6 to 8, the lid body 101 in the cup container 100 with a lid according to the present embodiment includes a main body plate 21, a peripheral wall 22, a second flange portion 102, and a mounting cylinder 103.
As shown in FIG. 7, three flange slits (slits) 102a and three flange ribs (ribs) 102b extending in the circumferential direction are spaced apart in the circumferential direction on the outer peripheral edge of the second flange portion 102. Open and formed.
The flange slits 102 a are formed on the left and right sides and the rear side of the second flange portion 102. That is, two of the three flange slits 102 a are disposed on both the left and right sides with respect to the central axis C that passes through the tip of the cutting edge portion 32 and is orthogonal to the cup axis O in a top view.
The three flange ribs 102b are arranged outside the flange slit 102a in the cup radial direction and extend over the entire length of the flange slit 102a.

  As shown in FIGS. 6 and 8, a plurality of support protrusions 103 a that are engaged with the lower surface of the first flange portion 11 b of the cup body 2 are directed toward the inner side in the cup radial direction on the inner peripheral surface of the mounting cylinder 103. It protrudes at intervals in the circumferential direction. Three of the plurality of support protrusions 103a are provided at positions overlapping the flange slits 102a formed in the second flange portion 102 in the circumferential direction in plan view.

  In addition, a release slit 104a is formed at the front end portion of the puncture portion 104 formed on the main body plate 21 over the entire length in the vertical direction, and the puncture portion 104 is opened forward. Thus, by heating the cup container 100 with the lid before opening the cup body 11, the internal pressure of the cup body 11 rises and the sealing material 14 bulges upward, and the puncture portion 104 causes the sealing material 14 to be deformed. When puncturing, the flow path between the cup body 2 and the outside of the puncture portion 104 is secured through the release slit 104 a, and the pressure of the cup body 11 is released to the outside of the cup body 11.

  In the cup container 100 with a lid having such a configuration, in order to attach the lid body 101 to the cup body 11, the second flange portion 102 is placed with the lid body 101 placed on the first flange portion 11 b of the cup body 11. When the whole is pushed in from above, the portion of the mounting cylinder 103 corresponding to the flange rib 102b in the circumferential direction of the cup is pushed downward relative to the other portion corresponding to the height of the flange rib 102b. Therefore, a portion of the mounting cylinder 103 corresponding to the flange slit 102a in the circumferential direction of the cup is elastically deformed outward in the radial direction of the cup relative to the other portion, and a support protrusion formed corresponding to the flange rib 102b in the circumferential direction of the cup. The portion 103a gets over the outer peripheral edge of the first flange portion 11b and engages with the lower surface of the first flange portion 11b. Thereafter, even if the pushing of the lid 101 is released, the locked state of the support protrusion 103a with respect to the lower surface of the first flange portion 11b is maintained.

  According to the cup container 100 with the lid according to the present embodiment, the lid body 101 is opened at the upper end of the cup body 11 by forming the flange rib 102b corresponding to the flange slit 102a in the circumferential direction of the cup with the second flange portion 102. The mounting operation by pushing from above while being placed on the portion 11e can be stabilized. Therefore, the lid body 101 can be easily and reliably fitted to the cup body 11.

  The present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.

For example, in the above embodiment, the leading blade 36 and the surrounding wall 37 are provided, but these may not be provided.
Moreover, in the said embodiment, although the cutting blade 35a sharpened toward the downward direction was shown in the lower end part of the unsealing blade 35, it showed the structure formed in multiple numbers along the left-right direction, but only one cutting blade 35a was shown. It may be present, or may be changed as appropriate, for example, by forming a plurality in the front-rear direction.
Moreover, in the said embodiment, although the hinge formed more thinly than the main body board 21, the cutting blade part 32, and the operation part 34 was shown as the 1st, 2nd rotation parts 31 and 33, it is not restricted to this but suitably It may be changed.
Furthermore, in the above embodiment, the three flange slits and the three flange ribs are formed with a gap in the circumferential direction of the cup. The flange slits and the flange ribs may be formed by two or four or more.
Moreover, in the said embodiment, although the sealing material 14 and the overcap 13 were provided, these presence or absence and its structure may be changed suitably.

  In addition, it is possible to appropriately replace the constituent elements in the above-described embodiments with well-known constituent elements without departing from the spirit of the present invention, and the above-described modified examples may be appropriately combined.
