Description

  The present invention relates to a cup holder sheet that is wound around a tapered cup, and a cup holder made of the cup holder sheet.

  In restaurants, vending machines, events, baseball fields, etc., beverages may be provided in a tapered cup. Since cups used for such purposes are often disposable, they are usually formed of thin paper or thin plastic from the viewpoint of low cost and low resources. Hereinafter, this type of cup is referred to as a simple cup.

  By the way, drinks poured into a cup are usually hot or cold depending on the season. However, since the simple cup is thin, there is no heat retaining property and cold retaining property, and the temperature of the beverage or the like changes significantly in a short time. In particular, in the case of a cold beverage or the like, the heat of the palm is transmitted from the simple cup to the beverage, so that it becomes warmer in a shorter time. In addition, when the heat or cold of a beverage or the like is transmitted to a palm through a thin simple cup, it may be uncomfortable.

  Therefore, as a cup holder that eliminates the discomfort transmitted to the palm, a strip-shaped paper (cup holder sheet) in which corrugated sheet or embossed paper is bonded to flat paper is used to form a tapered shape (paper product) ) Is publicly known (Patent Document 1).

  Further, as a cup holder sheet having heat retaining properties and cold retaining properties, a cup holder sheet using an elastic heat insulating plate made of foamed plastic or foamed rubber is known (Patent Document 2).

  However, in any case, a sufficient heat insulating effect cannot be obtained. More specifically, in the case of a cup holder using strip-shaped paper, when viewed in plan, the cup holder is used in such a form that the inner side (corrugated sheet type) of paper is surrounded by a wave. Then, even if the top (inner side) of the corrugated paper is in contact with the cup, the bottom (outer side) of the paper is separated from the cup. And the space formed between the cups penetrates in the vertical direction, and the heat transmitted from the cup escapes in the vertical direction as it is.

  In the case of foamed plastic, etc., the heat insulating effect depends on the volume of bubbles formed in the heat insulating plate. Therefore, in order to obtain a sufficient heat insulating effect, the thickness of the heat insulating plate is increased by increasing the material per piece. Must be thickened.

  This invention considers the said situation and an object of this invention is to provide the cup holder sheet | seat and cup holder which can obtain the heat insulation effect more than thickness.

  The cup holder sheet of the present invention is a piece of plastic provided with an arc-shaped belt-like cover that covers the tape-shaped cup and a connecting piece that extends from one end in the arc direction of the cover and overlaps the other end. The cover includes a non-contact portion that is separated from the cup and a contact portion that surrounds the non-contact portion and contacts the cup, and the non-contact portion swells in the thickness direction with respect to the contact portion. It is a heat insulation chamber and is provided at intervals in the arc direction.

Since the plastic sheet is difficult to bend, it is difficult to follow the tapered surface of the cup. To make it easier, the following is desirable.
That is, the contact portion includes an upper contact portion that is brought into contact with the upper side of the cup, a lower contact portion that is brought into contact with the lower side, and a middle contact portion that is installed with an interval in the arc direction between the upper and lower contact portions. Each middle contact portion includes a fold extending radially from the center of the arc.

Similarly, in order to facilitate the cover along the tapered surface of the cup, it is desirable to do the following.
That is, the contact portion is curved so as to be in surface contact with the tapered surface of the cup.

The means for fixing the connecting piece to the cover is not limited, and adhesion, heat welding, or the like may be used. However, in order to fix using the plastic sheet, the following is desirable.
In other words, the non-contact portion and the connecting piece of the cover to be overlapped are provided with a locking portion and a locked portion that can be fitted and removed. Moreover, the thickness as the whole cup holder sheet | seat can be made thin by forming a latching | locking part and a to-be-latched part within the range of the swelling of a non-contact part.

Since the cup holder sheet is a plastic sheet, the space for storage can be reduced by stacking, but since it is used by being attached to the cup, it takes time to assemble the cup holder. For example, when a beverage is provided to a large number of customers in a short time, it is assumed that the assembly time cannot be sufficiently secured. Therefore, it is desirable to have a cup holder that can keep the space to be stored as small as possible while being in an assembled state in advance.
In other words, the cup holder means that the connecting piece of the cup holder sheet of the present invention is overlapped and fixed to the other end portion in the arc direction of the cover so that the whole has a tapered shape.

  According to the cup holder sheet of the present invention, a tapered cup holder can be manufactured by overlapping the connecting piece on the other end on one end of the cover and fixing the overlapping portion. And if the cup holder is put on the cup, the cover is stabilized by the contact portion coming into contact with the cup, and the non-contact portion is surrounded by the contact portion, so that the non-contact is a heat insulation chamber. A heat-insulating space is formed between the cup and the cup, and a sufficient heat-retaining effect greater than the wall thickness can be obtained while being a single plastic sheet.

  Further, if the upper, middle, and lower contact portions are provided, the two adjacent middle contact portions and the upper and lower contact portions facing each other can be formed into a rectangular frame shape to improve the overall strength. In addition, since the fold portion is easily bent, the contact portion is easily brought into contact with the cup, and the heat insulating effect is improved.

  Furthermore, if the contact portion is curved so as to come into surface contact with the tapered surface of the cup, the contact between the contact portion and the cup becomes closer, and the heat insulation effect is improved accordingly.

  Moreover, since the latching | locking part and to-be-latched part which can be attached / detached are distributed and provided in the overlap part of the connection piece and the non-contact part of a cover, these can be fitted and fixed. Moreover, since the latching | locking part and the to-be-latched part are formed within the range of the swelling of a non-contact part, the thickness of the whole cup holder sheet | seat is restrained and the space to store can be made small.

  Since the cup holder of the present invention is formed using the cup holder sheet of the present invention, it has the same effect as described above. Moreover, since it has already been assembled, it is not necessary to assemble at the site of use, and the work efficiency of providing the original drink is improved accordingly. Moreover, since the whole is taper-shaped, it can be stored so that it may overlap inside, and the space to store does not need to be taken more than necessary.

It is a perspective view which shows the use condition of the cup holder of 1st Embodiment. It is a transverse cross section with an important section enlarged view showing the use state of the cup holder sheet of a 1st embodiment. (A) and (B) are cross-sectional views showing a procedure for manufacturing a cup holder from the cup holder sheet of the first embodiment. It is a perspective view which shows the stacked state of the cup holder of 1st Embodiment.

  The use object of the cup holder sheet and the cup holder of the present invention is a tapered cup. The cup may be of any thickness and material, but as an example, a simple cup made of thin-walled plastic that can be deformed when it is held strong and restored when the force is released can be mentioned.

  The cup holder sheet 1 of the first embodiment of the present invention is a single rigid plastic sheet as shown in FIGS. This rigidity is such that when an external force is applied, the plastic sheet can be bent, and when the external force is released, it returns to its original state. Moreover, the thickness of a plastic sheet is 1 mm or less, for example, It is 0.2 mm-0.5 mm desirably.

  The plastic sheet is a transparent sheet that is generally flat and uneven in the thickness direction. For example, the cover 2 is formed by vacuum forming and is wrapped around the cup 90, and a connecting piece for maintaining the cover 2 in a tapered shape. 3 is provided. Further, the connecting piece 3 that is superposed on one end portion in the arc direction of the cover 2 that has an arc shape as a whole and extends to the other end portion on the opposite side is extended along the arc direction. In the illustrated example, the end on the left side in the arc direction is provided with a connecting piece 3 in the middle in the radial direction (hereinafter referred to as “vertical width direction”) with respect to the virtual center of the arc, and the right end in the arc direction. The part is provided with connecting pieces 3 on the inner and outer parts in the longitudinal direction.

  The cover 2 has an arc-like shape as a whole, and includes a contact portion 4 that contacts the cup 90 and a non-contact portion 5 that is separated from the cup 90, and surrounds the non-contact portion 5 with the contact portion 4. .

  The contact portion 4 includes an upper contact portion 41 that contacts the upper side of the cup 90, a lower contact portion 43 that contacts the lower side, and an intermediate contact portion 42 that contacts the inner side of the cup 90. A middle contact portion 42 is installed between 43 and a plurality of middle contact portions 42 are provided at equal intervals in the arc direction. In the illustrated example, the middle contact portion 42 enters a region of the upper contact portion 41 and the lower contact portion 43 in the longitudinal width direction that is the installation direction. For this reason, the upper and lower contact portions 41 and 43 have an arc shape as a whole, but in detail, arc-shaped horizontal belt portions 41a and 43a are provided at equal intervals in the arc direction. And it becomes a form where the edge part of the middle contact part 42 intervenes between the adjacent horizontal strip parts 41a and 43a. Moreover, the surroundings of each non-contact part 5 (the heat insulation chamber mentioned later) are enclosed in a frame shape as a whole by the opposed upper and lower horizontal belt parts 41a, 43a and two middle contact parts 42 adjacent to them. The contact portion 4 is formed by a set of portions surrounded in such a frame shape.

  The horizontal band portions 41 a and 43 a of the upper and lower contact portions 41 and 43 are curved in advance so as to make surface contact with the tapered surface of the cup 90. For the same purpose, the upper horizontal band portion 41a is formed so that its upper side swells in an arc shape toward the upper side. Similarly, the lower horizontal band portion 43a has its lower side on the lower side. It is formed so as to swell in an arc shape. Accordingly, at least the upper and lower contact portions 41 and 43 of the contact portion 4 are curved so as to be in surface contact with the tapered surface of the cup 90 for each portion surrounding the non-contact portion 5.

  The middle contact portion 42 is provided with a perforation 42a (dotted hole (cut)) as a fold extending in the longitudinal width direction (radially from the virtual center of the arc) in the middle portion in the lateral width direction (arc direction). Yes. This perforation 42a becomes a fold line.

  The non-contact part 5 has a vertically long shape extending in the vertical width direction, swells in the thickness direction with respect to the contact part 4, and becomes a heat insulating chamber that opens toward the contact part 4 side (the cup 90 side). Yes. When the contact part 4 is brought into contact with the cup 90, the opening of the heat insulating chamber is closed by the cup 90, and the heat insulating space 5 a is formed outside the cup 90. The non-contact portion 5 includes a frame wall portion 51 that protrudes in the thickness direction from the inside of the frame-shaped contact portion 4 and an outer wall portion 52 that closes the protruding front end side of the frame wall portion 51. And the outer wall part 52 is spaced apart from the cup 90 in the radial direction and is in a substantially parallel state. More specifically, the outer wall part 52 is curved in advance so as to follow a virtual taper corresponding to the separated position.

The connecting piece 3 has a band shape extending along the arc direction, and has a shape in which irregularities are formed along the contact portion 4 and the non-contact portion 5 to be overlapped. In addition, each connecting piece 3 and a non-contact portion 5 that overlaps each connecting piece 3 are provided with a locking projection 6 as a locking portion that can be fitted and removed and a locking recess 7 as a locking portion. Formed. In the illustrated example, a locking recess 7 is formed on the connecting piece 3 and the non-contact portion 5 that is in contact with the cup 90 (the non-contact portion 5 at the right end in FIG. 1 (C)), and the other A locking projection 6 is formed on the connecting piece 3 at the left end of the figure. Specifically, a part of the outer wall part 52 of the non-contact part 5 and a part of the connecting piece 3 (a part of the part corresponding to the outer wall part 52 of the non-contact part 5) protrude to the same height as the contact part 4. The protruding amount is within the range of swelling of the non-contact portion 5.
Moreover, this protrusion part is made into the latching convex part 6 or the to-be-latched recessed part 7, and these are comprised from the top wall parts 62 and 72 which block the front-end | tip of the cylindrical parts 61 and 71 and the cylindrical parts 61 and 71. Thus, the locking projection 6 can be fitted into and removed from the locked recess 7. More specifically, the two connecting pieces 3 spaced apart in the longitudinal width direction at the end of the arc direction of the cover 2 and the non-contact portion 5 closer to the connecting pieces 3 are covered with a taper. A locking concave portion 7 is formed, and the remaining one connecting piece 3 and a non-contact portion 5 closer to the connecting piece 3 are formed with a locking convex portion 6 protruding in a tapered manner.

  As shown in FIG. 4, the cup holder sheet 1 according to the first embodiment is a plastic sheet in which the connecting piece 3 is overlapped with the non-contact part 5 of the cover 2, and the locking convex part 6 and the locked concave part 7 are formed. The cup holder 10 of the first embodiment having a tapered shape as a whole is obtained by fitting using the elasticity of the first embodiment. The to-be-latched recessed part 7 and the latching convex part 6 become a form which protrudes toward the inner side of the cup holder 10. As shown in FIG. Moreover, since this protrusion amount exists in the range of the swelling of the non-contact part 5, the thickness as a whole at the time of becoming a taper shape may be thin. Therefore, even if a plurality of cup holders 10 are overlapped as shown in FIG. 5, the height can be kept low.

  Further, when the cup 90 is a simple cup, the simple cup 90 and the cup holder 10 are partially overlapped by covering the cup holder 10 around the cup 90 so that the thin cups overlap. However, the rigidity as a whole is improved and it becomes difficult to deform even if it is firmly held. In addition, since the cup holder 10 is transparent, if the simple cup 90 is transparent, the liquid in it can be seen through from the outside.

  The present invention is not limited to the above embodiment. For example, the upper contact portion 41 is not limited to a configuration in which the end portion of the middle contact portion 42 is interposed between the horizontal belt portions 41a adjacent to each other in the arc direction, that is, a mode in which the upper contact portion 41 is provided with an interval in the arc direction. In this case, the middle contact portion 42 is interposed only in the range between the upper and lower contact portions 41 and 43. The same applies to the lower contact portion 43. Further, the middle contact portion 42 has a flat plate shape, but may have a shape curved in advance so as to be in surface contact like the upper and lower contact portions 41 and 43. In this case, the middle contact portion 42 is symmetrical with respect to the perforation 42a. It becomes a shape that curves to

In addition, the crease is not limited to one in which a number of short holes such as the perforation 42a are provided in a straight line, and may be one in which several long holes are provided.
In addition, the locking portion and the locked portion are not limited to a configuration that can be inserted and removed by the concave portion and the convex portion, but may have other configurations such as a slit-like cut-out and an arrowhead-shaped shape. May be.
In addition, you may fix the connection piece 3 to the cover 2 by adhesion | attachment etc., without providing the latching convex part 6 or the to-be-latched recessed part 7. FIG.
