Description

  The present invention relates to a cup storage case that can be attached to an article such as a bottle-type container while the cup is stored.

  Conventionally, various packaging materials have been used as cases for wrapping cups. Of these, cup storage cases in which sheet materials such as synthetic resin sheets and cardboard are assembled are frequently used because they can be manufactured at a relatively low cost and can be folded and stored flat when not in use.

By the way, the cup is not only sold by itself, but also may be sold attached to other articles. For example, there is a system in which a cup is attached to a bottle-type container containing a beverage for sale.
Conventionally, a cup storage case 100 as shown in FIGS. 10 and 11 is used in such a sales system.
This cup storage case 100 is formed by assembling sheet materials, and has three sides of a rectangular parallelepiped case main body 120 having an upper surface opening type capable of storing the cup A therein, and an upper surface opening portion 123 of the case main body 120. And a holding piece 130 that holds the cup A in a non-detachable manner in contact with the opening end of the stored cup A by being bent inward.
The three holding pieces 130 are formed with insertion holes 140 having a smaller diameter than the opening of the cup A. In the cup storage case 100, after the cup A is put in the case main body 120, the holding pieces 130 are sequentially folded and stacked, and the holding piece 130 to be finally bent is fixed to the case main body 120, whereby the upper end of the cup A is opened. Can be stored and held by the holding piece 130, and the insertion port 140 of the holding piece 130 communicates with the opening of the cup A.
As shown in FIGS. 12 and 13, the cup storage case 100 can be attached by inserting the neck portion of the bottle-shaped container B into the insertion port 140 of the storage case 100 that has already been stored.

Furthermore, in the conventional cup storage case 100, the neck of the inserted bottle-shaped container B hits the inner peripheral surface of the cup A during transportation or the like, and the cup A may be damaged. For this reason, a buffer member 150 is separately interposed between the neck of the container B and the inner peripheral surface of the cup A. As the buffer member 150, a member formed by folding cardboard so as to wrap the neck portion of the bottle-type container is used.
However, since the cup storage case 100 and the buffer member 150 are separate bodies, when storing the cup A, they must be assembled together. Therefore, the cup storing operation becomes complicated. Moreover, since both are separate bodies, it is necessary to produce two different members, and the product cost increases accordingly.

Further, the conventional cup holding case 100 may be inadvertently detached from the inserted bottle-type container B, and an improvement thereof is also desired.
Furthermore, the size of the insertion port 140 of the conventional cup holding case 100 is determined according to the diameter of the neck of the bottle-type container B. Specifically, when the opening diameter of the insertion port 140 is much larger than the diameter of the neck portion of the bottle-type container B, the cup storage case 100 inserted into the neck portion is shaken and inferior in stability. Therefore, considering the stability of the cup storage case 100, it is preferable that the opening diameter of the insertion port 140 is formed so as to match the diameter of the neck portion of the bottle-type container B. However, the cup storage case 100 formed in this way can be attached only to the bottle-shaped container B having a specific shape, and there is a problem that the versatility is inferior.

Accordingly, the present invention can prevent the housing the cup is broken, and on which can perform the storage work cup relatively simple, inadvertently disengaged hard cup storage case from the article such as a bottle type container Providing is a first problem.
Furthermore, this invention makes it the 2nd subject to provide the cup storage case excellent in the versatility which can be easily attached also to articles | goods of a different shape.

In view of the above problems, the present invention is formed by assembling a sheet material, and is provided continuously from a top opening type case body capable of storing a cup and two opposing edges of the top opening portion of the case body. A pair of holding pieces, and a pair of extended pieces respectively connected from other two opposing edges in a direction orthogonal to the two opposing edges of the case body, and by bending each holding piece inward A holding surface portion that is in contact with the opening end of the stored cup is formed, and further, a buffer surface portion that can be in contact with the inner peripheral surface of the cup is formed by bending the middle portion of each holding piece toward the inner peripheral surface of the cup. An insertion port through which a predetermined article can be inserted and removed is formed between the pair of bent holding pieces, and all or a part of the extended piece is bent from the insertion port toward the inner peripheral surface side of the cup. By the inner peripheral surface of the cup With buffer unit capable of is formed, the end of the buffer section of the extending portion provides a cup storage case, characterized in that it is engageable with the stepped portion of the inserted article from the insertion opening.

In the cup storage case, after the cup is placed in the case body, the holding piece is bent to form a holding surface portion that contacts the opening end of the stored cup, and a buffer that can contact the inner peripheral surface of the cup A surface portion is formed. Therefore, the cup is stored and held without coming out of the case body. Since an insertion opening is formed between the pair of bent holding pieces, a predetermined article (for example, a neck portion of a bottle-type container) is inserted into the insertion opening of the case that has been stored in the cup, and the case Can be attached to the article.
A buffer surface portion of the holding piece is interposed between the inserted article and the inner peripheral surface of the cup. The buffer surface portion is constituted by a part of the sheet material, and can be appropriately deformed to come into contact with the inner peripheral surface of the cup. Further, like the buffer surface portion, the buffer portion is interposed between the inserted article and the inner peripheral surface of the cup. Similar to the buffer surface portion, the buffer portion is composed of a part of the sheet material, and can be appropriately deformed to contact the inner peripheral surface of the cup, so that it functions as a buffer member for the article and the cup. Since the pair of buffer portions and the pair of buffer surface portions are respectively provided on two opposing edges that are orthogonal to each other, the buffer portion and the buffer surface portion are disposed around the inserted article. Therefore, the cup storage case can prevent the cup from being damaged during transportation or the like.
Moreover, since the edge part of a buffer part can be engaged with the step part of an insertion article, it can prevent that a cup storage case removes from an article carelessly. In addition, since this buffer part is formed in a pair so as to face each other, the end parts of both buffer parts engage so as to sandwich the inserted article.
Furthermore, since the cup storage case is formed by assembling sheet materials, it is not necessary to combine a separate buffer member as in the prior art, and the cup storage operation can be performed relatively easily.

Moreover, the preferable aspect of this invention provides the said cup storage case by which the edge part of the buffer surface part of the said holding piece is bend | folded so that the bottom part inner surface of the accommodated cup may be followed.
In this preferred cup storage case, the end portion of the bent buffer surface portion is interposed between the inserted article and the inner surface of the bottom portion of the cup. Therefore, even when the article is inserted deeply into the cup storage case so as to contact the bottom inner surface of the cup, the end of the buffer surface portion is interposed between the article and the bottom inner surface of the cup, and the cup is damaged. Can be prevented.

Moreover, the preferable aspect of this invention provides the said cup storage case by which a tongue-shaped surface part is formed in a part of said holding surface part, and this tongue-shaped surface part is extended to the insertion port.
In this preferred cup storage case, since the tongue-shaped surface portion extends to the insertion opening, the opening area of the insertion opening is reduced. Since the tongue-like surface portion is constituted by a part of the sheet material, it can be appropriately deformed. For this reason, the tongue-shaped surface portion is appropriately deformed according to the shape of the article inserted into the insertion port, allowing the insertion of an article having a different shape, the tongue-shaped surface portion being in contact with the outer surface of the article, and the case against the article Can be controlled.

The cup storage case according to the present invention can be attached to an article such as a bottle-type container while preventing the cup from being damaged. In addition, the cup storage case of the present invention can perform cup storage work relatively easily, and the unit price of the product can be kept relatively low.
In addition, according to the present invention, it is possible to provide a cup storage case that is difficult to inadvertently come off from an article such as a bottle-shaped container.
Furthermore, in a preferable aspect of the present invention, it is possible to attach to an article having a different shape, and it is possible to provide a cup storage case having excellent stability after the attachment.

Hereinafter, the present invention will be specifically described with reference to the drawings.
In FIG. 1, 1 shows the cup storage case of one Embodiment of this invention. In FIG. 1, the cup A is indicated by a two-dot chain line, and some folds are indicated by a one-dot chain line.
The cup storage case 1 is formed by assembling sheet materials, as will be described later.
The cup storage case 1 includes a case main body 2 having an upper surface that can store the cup A, a holding piece 3 that holds the cup A stored in the case main body 2 from the inside of the case main body 2 so as not to be removable. Have
The holding pieces 3 are continuously provided from two opposite edges of the upper surface opening of the case body 2. The holding piece 3 is bent inward to hold the holding surface portion 31 in contact with the opening end A1 of the stored cup A, the buffer surface portion 32 that can come into contact with the inner peripheral surface of the cup A, and the inner surface of the bottom portion of the cup A. A holding surface portion 33 in contact therewith. Between the pair of bent holding pieces 3 and 3, an insertion port 4 (see FIG. 3B and the like) for insertion into an article (for example, a neck portion of a bottle-type container) is formed. Further, the holding surface portion 31 is formed with a tongue-shaped surface portion 34 extending to the insertion port 4.
Further, a pair of extending pieces 5 and 5 are connected to other two opposing edges in a direction orthogonal to the two opposing edges of the case body 2.
The extension piece 5 is bent inward and overlapped with the holding surface portion 31 of the holding piece 3, and the restraining portion 51 for stopping the holding surface portion 31 and the inner peripheral surface of the cup A by being bent into the case body 2. And a buffer portion 52 that can come into contact with.

The cup A stored in the cup storage case 1 of the present invention is not particularly limited as long as it has a bottomed cylindrical shape having a drinking mouth. The shape of the cup A is, for example, a concave shape in the longitudinal section, and typically, a bottomed cylindrical shape as illustrated is exemplified, but a bottomed square cylindrical shape, a bottomed elliptical cylindrical shape, a bottomed hexagonal shape is exemplified. Other shapes such as a cylindrical shape may be used. Further, the cup A may have a handle formed on the outer peripheral surface within a range that can be accommodated in the case body 2.
Also, the material of the cup A is not particularly limited, and may be a known material such as ceramic, glass, synthetic resin, metal, or wood. However, since the cup storage case 1 of the present invention is excellent in shock-absorbing properties, it has a particularly remarkable effect when a ceramic or glass cup A is stored.
In addition, cup A means the equipment which can be used for drinking of a liquid, and is a meaning including what is generally called a glass, a hot water drink, a cup, etc.

The cup storage case 1 is formed by assembling a flexible sheet material.
As the sheet material, it is possible to use various types of sheets such as polyolefins such as polypropylene and polyethylene, polyesters such as polyethylene terephthalate, various synthetic resin sheets such as polystyrene and polyamide, paper, and synthetic paper. The sheet material may be the same type or different type of laminated sheet. Especially, since the accommodated cup etc. can be visually recognized from the outside, it is preferable to use a transparent (colorless transparent or colored transparent) sheet material.
The thickness of the sheet material is not particularly limited. For example, in the case of a synthetic resin sheet, the thickness is about 0.2 mm to 1.0 mm.
Especially, since it has moderate rigidity and a softness | flexibility, it is preferable to use the sheet | seat of the transparent polypropylene about 0.2 mm-0.6 mm in thickness.

Next, FIG. 2 shows a spread sheet 10 constituting the cup storage case 1. In FIG. 2, all the folds are indicated by alternate long and short dash lines.
The spread sheet 10 is formed by punching one sheet material.
The spread sheet 10 is connected to the first to fourth side surface forming portions 11 constituting the four side surface portions of the case body and the lower side of the side surface forming portion 11 and is locked with an adhesive or each other. The bottom surface forming portion 12 constituting the bottom surface portion of the case body 2, the holding piece forming portion 13 connected to the upper sides of the first and third side surface forming portions 11 and 11 and constituting the holding piece 3; 2 and the fourth side surface forming portions 11, 11, respectively, and the extended piece forming portion 15 constituting the extending piece 5, and the glue connected to the side sides of the fourth side surface forming portion 11. A surrogate forming portion 16.
A crease is formed at a continuous boundary portion of each forming portion 11. In addition, substantially fan-shaped cuts 14 are formed from both ends of the fold in the surface of the holding piece forming portion 13. The range surrounded by the cut 14 constitutes the tongue-like surface portion 34 of the holding piece 3. Further, in the surface of the extended piece forming portion 15, a substantially circular cut line 17 that does not cut a part (a crease is formed in a part) is formed. A range surrounded by the cuts 17 constitutes the buffer portion 52 of the extension piece 5. In addition, 18 shows the insertion piece part extended from one extension piece formation part, and 19 shows the cut for insertion.

  Here, the cut line is a cut line penetrating the sheet material. The fold line is an easy-bending line for easily folding the sheet material. As the fold line, for example, a half cut line (also referred to as a V notch) obtained by cutting the sheet material in the thickness direction, a perforation in which through holes are intermittently formed, or the like is preferably used.

Hereinafter, a specific configuration of the cup storage case of the present invention will be described in accordance with a procedure for storing the cup A while assembling the developing sheet 10.
The adhesive margin forming part 16 of the unfolded sheet 10 is bonded to the side surface of the first side surface forming part 11 to form a square cylinder. Next, the bottom surface forming portion 12 of the spread sheet 10 is combined to close the bottom surface opening of the square tube.
As a result, the case body 2 having an upper surface opening type as shown in FIG. 1 is assembled.

When the unfolding sheet 10 is used, the case main body 2 is formed in a bottomed square tube shape with an open top surface. Specifically, the case main body 2 includes four side surface portions 21 that are continuously provided by being bent at substantially right angles through folds, and a bottom surface portion 22 that is formed at the lower edge of the four side surface portions 21. . However, the case body 2 is not limited to a rectangular tube shape, and can be changed to other shapes such as a cylindrical shape and a hexagonal tube shape.
The size of the case main body 2 is formed in accordance with the size and shape of the cup A to be stored. For example, the case main body 2 has an outer peripheral surface of the cup A stored in the center of the four side surfaces 21. It is formed in the size which contacts.
The upper surface opening of the case body 2 is an opening for taking in and out the cup A.

Next, the cup A is inserted from the upper surface opening of the case body 2. The cup A is inserted with its opening facing the upper surface opening of the case body 2.
The holding piece 3 that can be bent is integrally connected to the edge of the upper surface opening of the case body 2 so that the stored cup A does not come out.
Specifically, the pair of holding pieces 3, 3 are connected to opposite two edges of the upper surface opening of the case body 2, respectively. Each holding piece 3 is formed of a substantially trapezoidal surface portion that becomes narrower toward the upper side of the case main body 2, and a fold 91 formed along the edge of the case main body 2 (hereinafter, this fold is referred to as a “first fold 91. In the following description, the folds formed in the respective constituent members can be bent through a second for convenience sake, but does not mean superiority or inferiority.

  In the surface of the holding piece 3, a second fold 92 and a third fold 93 are formed substantially parallel to the edge of the case body 2. A region defined by the first fold line 91 and the second fold line 92 is in contact with the opening end A1 of the cup A, and becomes a holding surface portion 31 that holds the cup A in a non-removable manner. Further, a region defined by the second fold line 92 and the third fold line 93 is interposed between the cup A and the inserted article, and serves as a buffer surface portion 32 that prevents the article from coming into contact with the cup A. Further, a region defined by the third fold 93 and the leading edge of the holding piece 3 is a holding surface portion 33 that contacts the inner surface of the bottom of the cup A.

  The formation interval of the first fold line 91 and the second fold line 92 (the length of the holding surface part 31) is such that the holding port part 31 is in contact with the opening end A1 of the cup A and the insertion port 4 is between the pair of holding pieces 3 bent. It is sufficient if it can be formed. For example, when the cup A having an opening diameter of about 8 cm is stored, the formation interval between the first fold line 91 and the second fold line 92 is formed to be about 1 cm to 3 cm. Further, the formation interval (the length of the buffer surface portion 32) of the second fold line 92 and the third fold line 93 is preferably about the same as the depth of the inner peripheral surface of the cup A.

After the case main body 2 shown in FIG. 1 is formed, as shown in FIG. 3A, one holding piece 3 is set at a substantially right angle with respect to the side surface portion 21 of the case main body 2 at the first fold 91. Bend inward so that The holding surface portion 31 of the bent holding piece 3 is in contact with and holds the opening end A1 of the stored cup A. Further, the holding piece 3 is bent into the inside of the case main body 2 so as to be substantially perpendicular to the holding surface portion 31 at the second fold 92, whereby the buffer surface portion 32 that can contact the inner peripheral surface of the cup A. Is formed. Further, the holding piece 3 is bent at the third fold line 93 so as to be substantially perpendicular to the buffer surface portion 32, thereby forming the holding surface portion 33 in contact with the bottom inner surface of the cup A.
Similarly, the other holding piece 3 is bent at the first fold line 91, the second fold line 92, and the third fold line 93 to form the holding surface part 31, the buffer surface part 32, and the restraining surface part 33 (FIG. 3). (B)).
When the both holding pieces 3 are bent in this way, the holding surface portion 31 closes a part of the upper surface opening of the case body 2, and the insertion port 4 is formed between the both holding surface portions 31 of the both holding pieces 3.

Further, the tongue-like surface portions 34 formed on the both holding surface portions 31 extend to the insertion port 4 and project. The tongue-shaped surface portion 34 is a portion surrounded by an arc-shaped cut 14 formed by dividing the first fold 91. By bending the holding piece 3 at the first fold 91, the tongue-like surface portion 34 is flush with the holding surface portion 31, protrudes inward from the first fold 91, and is formed between the both holding surface portions 31. It extends to the insertion opening 4.
Accordingly, the opening area of the insertion port 4 is reduced by an amount corresponding to the protruding area of the extended tongue-like surface portion 34.

Since the buffer surface portion 32 of the holding piece 3 faces the inner peripheral surface of the cup A and is made of a sheet material, it can be appropriately deformed when a force is applied from the outside.
Similarly, since the tongue-like surface portion 34 is made of a sheet material, it can be appropriately deformed when a force is applied from the outside.

On the other hand, a foldable extending piece 5 is integrally connected to the edge of the upper surface opening of the case body 2.
Specifically, a pair of extending pieces 5, 5 are provided on two opposite edges in a direction orthogonal to the opposite two edges where the pair of holding pieces 3 are arranged continuously, of the edges of the upper surface opening of the case body 2. Are connected. Each extending piece 5 is formed of a rectangular surface portion that is substantially the same shape as the upper surface opening of the case body 2, and can be bent through a fourth fold 94 formed along the edge of the case body 2.

In the surface of the extended piece 5, a fifth fold 95 is formed substantially parallel to the fourth fold 94, and a substantially circular cut 17 is formed from both ends of the fifth fold 95. The cut line 17 is formed in a region on the side opposite to the fourth fold line 94 (the front end side of the extension piece 5) with the fifth fold line 95 as a reference. Further, a pair of sixth fold lines 96 are formed in the region surrounded by the cut line 17. The sixth fold 96 extends in a direction substantially orthogonal to the fifth fold 95 and is formed from both ends of the fifth fold 95 to the cut 17.
The diameter of the cut line 17 is preferably substantially the same as or larger than the interval between the insertion ports 4 (the interval between the ends of the pair of holding surface portions 31 and 31 (second fold line 92)). Moreover, it is preferable that the formation interval of the pair of sixth folds 96, 96 is narrower than the interval between the tips of the tongue-like surface portions 34 protruding from the pair of holding surface portions 31, 31.
Note that an insertion cut 19 is formed at a boundary portion between the one extended piece 5 and the case body 2. An insertion piece 18 is connected to the tip of the other extension piece 5.

  After the pair of holding pieces 3 and 3 are bent, as shown in FIG. 4A, the region surrounded by the cut line 17 of the one extended piece 5 is the fifth fold 95 and the sixth fold 96. Bend each inside. By bending the area surrounded by the cut line 17, a substantially circular hole 53 corresponding to the shape of the cut line 17 is formed at the center of the extended piece 5. In addition, the area surrounded by the cut line 17 becomes the buffer portion 52 of the extension piece 5.

  Next, as shown in FIG. 4B, one extension piece 5 is bent inward at a fourth fold 94, and the extension piece 5 is overlapped on the upper surface of the holding surface portion 31 of the holding piece 3. . The bent extended piece 5 is substantially parallel to the holding surface portion 31, and a hole portion 53 formed in the extended piece 5 overlaps and communicates with the insertion port 4. And the buffer part 52 which can contact | connect the inner peripheral surface of the cup A is formed by bending the area | region enclosed by the cut 17 bent by the 6th fold 96 from the insertion port 4 to the inner peripheral surface side of the cup A. Is done.

Further, as shown in FIG. 5A, the other extension piece 5 is bent inward at the fourth fold 94 in the same manner, and as shown in FIG. 5B, one extension piece 5 is bent. Overlay the top surface of. The other extension piece 5 has a hole 53 that coincides with the hole 53 formed in the one extension piece 5 and overlaps the one extension piece 5 in parallel. Then, the area surrounded by the cut line 17 bent by the sixth fold line 96 is bent from the hole 53 of the one extended piece 5 toward the inner peripheral surface side of the cup A, whereby the inner peripheral surface of the cup A is formed. A buffer portion 52 that can contact is formed.
Finally, the holding piece 3 and the extending piece 5 are fixed to the case body 2 by inserting the inserting piece portion 18 of the other extending piece into the insertion cut 19 of the one extending piece.
The obtained cup packaging case 1 includes a pair of buffer surface portions 32 and 32 facing each other inside the cup A, and a pair of buffer portions facing each other in a direction orthogonal to the pair direction of the pair of buffer surface portions 32 and 32. 52, 52.

The storage case 1 storing the cup is used by inserting a predetermined article from the insertion port 4, for example.
The article is not particularly limited, but a drink container is preferable because a cup is attached. Examples of the beverage include alcohols and soft drinks. The shape of the article is not particularly limited as long as it has an insertion portion that can be inserted into the insertion port of the case 1, but a bottle-shaped container having a neck portion that can be inserted into the insertion port 4 is preferable.

FIG. 6 shows a configuration example in which the cup storage case of the present invention is attached to the bottle-type container B having the neck portion B1.
The bottle-type container B is placed on the placement surface with the neck B1 facing upward. The cup storage case 1 is attached to the bottle-type container B by inserting the insertion port 4 of the cup storage case 1 into the neck B1 of the bottle-type container B.
Between the neck B1 of the inserted bottle-type container B and the inner circumferential surface of the cup A, as shown in FIG. Since the buffer surface portion 32 is constituted by a part of the sheet material (holding piece 3) and is bent at the second fold 92, when the bottle-shaped container B is shaken, it is appropriately deformed and the inner periphery of the cup A Touch the surface.
Further, between the neck B1 of the inserted bottle B and the inner peripheral surface of the cup A, as shown in FIG. Since this buffer part 52 is comprised by a part of sheet material (extension piece 5), and is bend | folded by the 5th crease | fold 95, when the neck part B1 of the bottle-type container B shakes, it deform | transforms suitably and a cup A contacts the inner peripheral surface of A. The pair of buffer portions 52 and 52 are formed on a pair of extending pieces 5 and 5 that are continuously provided from two opposite edges in a direction orthogonal to the opposite two edges to which the holding pieces 3 and 3 are continuously provided. Therefore, a pair of buffer surface portions 32 and 32 and buffer portions 52 and 52 are arranged around the neck portion B1.
For this reason, a pair of buffer surface parts 32 and 32 and buffer parts 52 and 52 function as a buffer member between cup A and bottle type container B, and it can prevent that cup A is damaged at the time of conveyance etc.
In particular, as shown in FIG. 9A, the buffer portions 52, 52 formed on the extending piece 5 are bent toward the cup A at the sixth fold 96, and leg portions 52a that can come into contact with the cup A are formed. Is formed. Since the leg portion 52a is easily deformed when coming into contact with the inner peripheral surface of the cup A, the buffer portion 52 having the leg portion 52a is particularly excellent in a buffering effect.

  Further, the end portion of the buffer portion 52 engages with a stepped portion B2 formed on the neck portion B1 of the bottle-type container B as shown in FIGS. For this reason, it can prevent that the cup storage case 1 removes from the bottle-type container B carelessly. Since the end portion of the buffer portion 52 is engaged with the neck portion B1 of the bottle-type container B, it is possible to prevent the cup storage case 1 from coming off.

  Moreover, since a pair of tongue-shaped surface parts 34 are extended in the insertion port 4, when the bottle-shaped container B is inserted from the insertion port 4, as shown in FIG.7 and FIG.9 (b), the tongue-shaped surface part 34 is shown. Is appropriately deformed into an inclined shape and conforms to the shape below the neck portion B1 (the lower portion of the neck portion B1 of the bottle-type container B usually has a shoulder portion having a gradually increased diameter). When the tongue-shaped surface portion 34 is appropriately deformed and extends along the outer surface of the bottle-shaped container B, the cup storage case 1 can be inserted into the bottle-shaped container B while allowing the insertion of the bottle-shaped container B having a different shape of the neck B1. It can regulate swinging.

  Further, since the end portion (holding surface portion 33) of the holding piece 3 is bent along the bottom inner surface of the cup A, the bottom inner surface of the cup A and the top of the bottle-type container B as shown in FIG. The holding surface portion 33 is interposed therebetween. Such a restraining surface portion 33 can prevent the top of the bottle-shaped container B from coming into direct contact with the cup A. For this reason, even if the neck B1 of the bottle-shaped container B is long enough to contact the inner surface of the bottom of the cup, the cup A can be prevented from being damaged. Therefore, the stability of the cup storage case 1 is improved.

Note that the present invention is not limited to the above-described embodiment, and can be appropriately modified within the scope intended by the present invention.
For example, in the above-described embodiment, the buffer portion 52 of the extended piece 5 has the bent leg portion 52a, but may be transformed into a flat buffer portion 52 (without the leg portion 52a).
Moreover, in the said embodiment, although the buffer surface part 32 of the holding piece 3 is flat form, for example, a part of buffer surface part 52 (for example, both sides of the buffer surface part 52) is bent to the cup A side, and the said extension is carried out. Similarly to the buffer portion 52 of the protruding piece 5, a leg portion can be formed.
Furthermore, in the said embodiment, although the buffer part 52 of the extension piece 5 is formed in the substantially circular shape, for example, you may form in other shapes, such as a rectangular shape. In addition, other portions can be appropriately modified into a shape other than the shape shown in the above embodiment.
