It aims at providing the cup container with a lid which can prevent.

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 opening is sealed by a sealing member and a cutting blade member that breaks and opens the sealing member, and is a lid that is attached to the cup body. A cup container with a lid, comprising: an outer lid that is detachably attached to the lid body; and a pusher capable of depressing the cutting blade member toward the seal member inside the outer lid And the lid includes a side wall portion to which the outer lid is attached, and the side wall portion has the cutting portion of the pressing portion when the cutting blade member is pressed by the pressing portion. It is continuously provided toward the guide portion in the radial direction for guiding the movement toward the blade member and said Rukoto.

According to the present invention, since the sealing of the cup body is ensured at the time of opening, it is hygienic without touching the contents with a finger or the like, and the contents can be prevented from scattering to the outside. That is, since the outer lid is attached to the lid body, the cutting blade member is pressed through the pressing portion without directly pressing it with a finger or the like, and the finger or the like does not enter the cup body. For this reason, a finger etc. do not contact the contents. Further, since the lid is opened with the lid attached, the contents do not scatter outside the outer lid. Therefore, it is hygienic and can prevent the contents from being scattered outside.
Further, since the pressing portion is positioned with respect to the cutting blade member, the pressing blade can be stably pressed by the pressing portion.

Further, in the cup container with a lid according to the present invention, the lid body has a top surface portion that covers the top surface of the seal member, and the top surface portion is formed with a breaking opening through which the cutting blade member can pass. Preferably it is.
In this invention, since the movement of the cutting blade member is not hindered by the top surface portion when the cutting blade member is pressed by the pressing portion, the pressing blade member can be reliably pressed by the pressing portion.

In this invention, when the stopper convex portion is locked to the locking convex portion, the cutting blade member rotates again around the hinge portion after the seal member is broken, and when the content is taken out from the content, Even if a force that pushes back the cutting blade member acts on the cutting blade member, the movement can be suppressed and the opening portion of the seal member can be prevented from being blocked.

  According to the cup container with a lid according to the present invention, since the sealing of the cup body is ensured at the time of opening, it is hygienic without touching the contents with a finger or the like, and the contents can be prevented from scattering to the outside. .

  Hereinafter, a first embodiment of a cup container with a lid according to the present invention will be described with reference to the drawings. In each drawing used in the following description, the scale is appropriately changed to make each member a recognizable size.

As shown in FIGS. 1 and 2, the cup container 1 with a lid according to the present invention is, for example, filled with a beverage or the like and circulated. The user (consumer) purchases the beverage directly from the cup container. Can drink.
As shown in FIG. 1, the cup container 1 with a lid includes a cup body 11, a lid body 12, and an outer lid 13.

The cup body 11 has a substantially bottomed cylindrical shape extending along the axis L, and opens toward the upper portion by the opening 21. The cup body 11 includes a tapered barrel portion 22 that is reduced in diameter as it goes downward, and a bottom portion 23 that is connected to the lower end portion of the tapered barrel portion 22 and extends in a direction orthogonal to the axis L.
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 opening 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 seal member 25 attached to the opening 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. Further, the height in the direction of the axis M from the annular plane portion 34 is substantially the same as the sum of the thickness of the flange portion 24 and the thickness of the seal member 25.
Therefore, when the mounting cylinder portion 35 is put on the flange portion 24, the engaging convex portion 35A engages with the lower surface side of the flange portion 24, and the annular flat surface portion 34 contacts the upper surface of the flange portion 24 via the seal member 25. The lid body 12 is fixed to the cup body 11 in contact therewith. 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 portion 31 decreases toward the upper side, and when the user (consumer) drinks the beverage whose upper portion is filled in the cup body 11 with respect to the contact portion with the top surface portion 32. It is a mouthpiece.
Moreover, as shown in FIG. 2, the guide rib (guide part) which protrudes in the radial direction inner side of the cover body 12 in the circumferential direction outer side rather than the circumferential direction both ends of the cutting edge member 33 in the side wall part 31. 36 is continuously provided. The guide rib 36 guides the downward movement of the pressing portion 43 (described later) of the outer lid 13 when the seal member 25 is broken. Further, the height of the guide rib 36 is equal to that of the side wall portion 31.

As shown in FIG. 1, the top surface portion 32 is curved so as to protrude upward as it goes inward in the radial direction of the lid body 12. Thus, by making the top surface portion 32 into a curved shape, a space is formed in advance between the top surface portion 32 and the seal member 25. 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. Is prevented.
As shown in FIGS. 1 and 2, the top surface portion 32 is formed with a fracture opening 37 for allowing the cutting blade member 33 to rotate. The fracture opening 37 is formed larger than the cutting blade member 33 in plan view. Thereby, the sealing member 25 is broken by the cutting blade member 33 without being caught on the top surface portion 32.
In addition, a locking convex portion 39 that protrudes upward is formed in the vicinity of the hinge portion 38 at the edge portion of the top surface portion 32 that is close to the fracture opening 37. The height of the locking projection 39 is sufficiently lower than the side wall 31.

As shown in FIG. 1, the cutting blade member 33 has a substantially semi-cylindrical shape protruding upward, and is a hinge formed at an end portion on the radially inner side of the lid body 12 in the fracture opening 37. It is rotatably connected to the top surface part 32 via the part 38. In the cutting blade member 33, the radially inner end portion of the lid body 12 is connected to the top surface portion 32 via a hinge portion 38. Further, a cutting blade 33 </ b> A that protrudes toward the seal member 25 is formed at an end portion on the radially outer side of the lid 12 in the cutting blade member 33.
Further, in the vicinity of both end portions of the hinge portion 38 in the cutting blade member 33, a stopper convex portion 33B that protrudes downward is formed. The lower end portion of the stopper convex portion 33B can be locked with the locking convex portion 39 when the cutting blade member 33 is rotated around the hinge portion 38.

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 41 having a cylindrical shape with the axis N as a center, and a top plate portion 42 that is disposed at the upper end of the cylindrical portion 41 and covers the upper end opening of the cylindrical portion 41.
The cylindrical portion 41 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 41 with the outer circumferential surface of the side wall portion 31 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.

The top plate portion 42 is formed with a pressing portion 43 for pressing the cutting blade member 33 from above.
The pressing portion 43 is a concave portion that protrudes downward from the top plate portion 42, and its protruding amount is substantially the same as that of the cylindrical portion 41, and its bottom portion is located near the top surface of the top surface portion 32. . Further, as shown in FIG. 2, the shape of the outer periphery of the pressing portion 43 is substantially the same as the shape of the edge of the fracture opening 37 in plan view.
In a normal state in which the sealing member 25 is not broken by the cutting blade member 33, the pressing portion 43 does not overlap the pressing portion 43 and the cutting blade member 33 in plan view so as not to press the cutting blade member 33. It is shifted in the direction. For example, the pressing portion 43 is disposed on the opposite side of the cutting blade member 33 with respect to the axes L, M, and N in the radial direction of the lid-equipped cup container 1.

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, and the outer lid 13 is rotated in the circumferential direction so that the pressing portion 43 and the cutting blade member 33 overlap in a plan view. Then, by moving the cylindrical portion 41 of the outer lid 13 downward along the side wall portion 31 of the lid body 12, the lid body 12 is attached to the outer lid 13 as shown in FIG. 3. At this time, when the lid body 12 is moved downward along the side wall portion 31, the bottom portion of the pressing portion 43 comes into contact with the cutting blade member 33.
Then, the pressing portion 43 pushes down the cutting blade member 33 downward and rotates the cutting blade member 33 around the hinge portion 38. At this time, since the fracture opening 37 is formed in the top surface portion 32, the rotation operation of the cutting blade member 33 is not hindered by the top surface portion 32. Further, since the guide rib 36 is formed, the pressing portion 43 stably presses the cutting blade member 33 without being displaced in the circumferential direction of the outer lid 13.
By this turning operation, the tip of the cutting edge 33A comes into contact with the seal member 25, and the seal member 25 is broken. At this time, since the outer lid 13 is not broken, the sealed state in the cup body 11 is ensured. Therefore, the beverage does not scatter outside, and fingers or the like do not enter the cup body 11.

Further, when the cutting blade member 33 rotates around the hinge portion 38, the surface at which the lower end corner portion 33 </ b> C of the stopper convex portion 33 </ b> B provided on the cutting blade member 33 faces the radially outer side of the lid 12 at the locking convex portion 39. (See FIG. 4A). Then, as the cutting blade member 33 rotates around the hinge portion 38, the lower end corner portion 33C of the stopper convex portion 33B slides upward along the surface of the locking convex portion 39 while being elastically deformed. (See FIG. 4B). Thereafter, the lower end corner portion 33C of the stopper convex portion 33B is restored and deformed so that the lower end surface of the stopper convex portion 33B comes into contact with the surface of the engaging convex portion 39, so that the stopper convex portion 33B is engaged with the engaging convex portion 39. (See FIG. 4C and FIG. 5). This prevents the cutting blade member 33 from rotating around the hinge portion 38 and blocking the opening of the sealing member 25 where the cutting blade member 33 is broken.
As described above, the seal member 25 is opened. Thereafter, the user (consumer) can drink the beverage in the cup body 11 by removing the outer lid 13.

According to the cup container 1 with a lid in this embodiment, since the sealing state in the cup main body 11 is ensured when the sealing member 25 is opened, the beverage is prevented from splashing outside and is hygienic.
Further, since the pressing portion 43 is positioned in the circumferential direction of the outer lid 13 by the guide rib 36, the cutting blade member 33 can be stably pressed by the pressing portion 43.
Then, the movement of the cutting blade member 33 is not hindered by the top surface portion 32 due to the breaking opening 37, and the pressing portion 43 can reliably press the cutting blade member 33.
Furthermore, by connecting the cutting blade member 33 to the top surface portion 32 via the hinge portion 38, it is possible to prevent the cutting blade member 33 from being separated after the sealing member 25 is broken.
Further, by locking the stopper convex portion 33B to the locking convex portion 39, the cutting blade member 33 rotates again around the hinge portion 38 after the seal member 25 is broken, thereby closing the opening formed in the seal member 25. Can be prevented.

  Next, 2nd Embodiment of the cup container with a lid in this invention is described. The embodiment described here has the same basic configuration as the first embodiment described above, and is obtained by adding another element to the first embodiment described above. Therefore, in FIG.6 and FIG.7, the same code | symbol is attached | subjected to the same component as FIGS. 1-5, and this description is abbreviate | omitted.

As shown in FIG. 6, the cup container 50 with a lid according to the present embodiment includes a cup body 11, a lid 51, and an outer lid 13.
The lid body 51 includes a side wall portion 31, a top surface portion 32, and a cutting blade member 33.
As shown in FIGS. 6 and 7, a guide wall portion (guide portion) 52 surrounding the edge portion of the fracture opening 37 is connected to the side wall portion 31.
Similar to the guide rib 36 in the first embodiment described above, the guide wall portion 52 surrounds the outer peripheral surface of the pressing portion 43 of the outer lid 13 when the seal member 25 is broken, so that the lower portion of the pressing portion 43 is provided. Guide the move to. Further, the height of the guide wall 52 is the same as that of the side wall 31. And the guide wall part 52 can be latched with the latching convex part 39, when the cutting blade member 33 is rotated around the hinge part 38 similarly to the latching convex part 39 in 1st Embodiment mentioned above. It has become.

The opening method of the lid-equipped cup container 50 having the above-described configuration is the same as that of the lid-equipped cup container 1 in the first embodiment described above. That is, the outer lid 13 is moved downward in a state in which the pressing portion 43 and the cutting blade member 33 overlap in a plan view. At this time, since the outer peripheral surface of the pressing part 43 moves downward along the guide wall part 52, the movement of the pressing part 43 is stabilized.
Then, the pressing portion 43 pushes down the cutting blade member 33 downward and rotates the cutting blade member 33 around the hinge portion 38. By rotating the cutting blade member 33 in this way, the cutting blade 33A breaks the seal member 25 and opens it. At this time, the stopper convex portion 33 </ b> B is locked to the guide wall portion 52. This prevents the cutting blade member 33 from rotating around the hinge portion 38 and blocking the opening of the sealing member 25 where the cutting blade member 33 is broken.
As described above, the seal member 25 is opened.

  The lid-equipped cup container 50 in the present embodiment also has the same operations and effects as the lid-equipped cup container 1 in the first embodiment described above, but in a state where the pressing portion 43 is surrounded by the guide wall portion 52. Therefore, the movement of the pressing unit 43 is more stable.

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 opening structure of the seal member is such that the pressing portion presses the cutting blade member to open the outer lid once the outer lid is once removed from the lid and then the outer lid is attached to the lid again. The pressing unit may be configured to press the cutting blade member by relatively rotating the lid body around the axis.
Further, if the opening formed in the seal member is not closed again by the cutting blade member, the stopper convex portion may not be configured to be locked to the locking convex portion.
And although the cutting blade member can be rotated centering on a hinge part, it is good also as another structure.
Furthermore, if the opening can be formed in both the sealing member and the top surface portion when the cutting blade member is pressed, the break opening portion does not need to be formed in the top surface portion.
Further, the guide rib and the guide wall portion are not limited to either one, and both may be formed. The guide rib and the guide wall portion do not need to be formed as long as the pressing member can be stably pressed by the pressing portion.
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.
