Description

  The present invention relates to various cup-shaped containers made of paper, plastic, glass, etc., and particularly to a simple cup holder used to hold a cup-shaped container having a tapered shape with a diameter larger toward the upper end opening side. is there.

  2. Description of the Related Art A relatively thin-walled cup-shaped container made of paper or plastic is used as a cup for serving drinks or the like in a fast food restaurant or various vehicles. Such a cup-shaped container made of paper or the like cannot be directly gripped when the heated drink is put as it is because the container side surface is hot. There are paper cup-like containers with handle pieces attached to the side of the container, but there is a problem with stability when the container is lifted in a car etc., and in making the container, handle pieces made in a separate process are used. It is necessary to adhere to the side surface of the container, which increases the number of processes and makes the container itself expensive.

  In order to solve the above-mentioned problems in this type of cup-shaped container, as seen in Patent Document 1 and Patent Document 2, a cup holder made of a single sheet of paper has been proposed.

  The cup holder of Patent Document 1 is formed by forming a handle plate on a part of the outer periphery of the bowl-shaped edge fitted to the oblique side surface of the cup-shaped container. The cup-shaped edge is fitted to the side surface of the cup-shaped container. In this state, the handle plate is bent and bent downward so that its inner end is brought into contact with the side surface of the container so that the handle plate is gripped like a handle. Since it is not what is gripped, rattling and slipping are likely to occur, and the gripping state may become unstable. Moreover, even if it is formed by punching from a single sheet of paper, the inside of the bowl-shaped edge becomes a waste allowance to be punched, and a portion protruding outward from the bowl-shaped edge to form the handle plate Therefore, the use area of the paper material for one holder in production becomes large, the number of papers taken from one paper material is small, the material cost is high, and the cost is high.

Also, in the case of the cup holder of Patent Document 2, a side plate or a bottom plate that receives the bottom of the container is connected to the outer periphery of a ring-shaped bowl-shaped plate that fits on an oblique side of the cup-shaped container. Because it is constructed, it is troublesome to assemble in use, and side plates etc. are connected to the outer periphery of the bowl-like plate, so the area of paper material used for one holder is also large. The number of sheets taken from one sheet is small, and the cost is high as a disposable cup holder.

  The present invention has been made in view of the above, and provides a simple cup holder that can hold a cup-shaped container with stability, can be easily and efficiently manufactured, and can be obtained at low cost. Is.

  The cup holder of the present invention that solves the above problems is formed of a single heat insulating sheet material, and is connected to an annular flange-shaped plate portion that fits on an oblique side surface of the cup-shaped container, and an inner periphery thereof. A cup holder having a gripping piece, wherein the flange-shaped plate portion is formed by a plurality of cuts formed by leaving a connecting portion at a predetermined interval in the circumferential direction along the inner periphery thereof. The inner plate portion is divided into a plurality of portions that are continuous with the connecting portions, and each of the divided portions is a gripping piece that can be bent at the connecting portion with respect to the flange-like plate portion. It is formed.

  In use of this cup holder, the inner periphery of the flange-shaped plate portion is bent in a downward direction with a plurality of gripping pieces connected to the inner periphery of the flange-shaped plate portion fitted to the side surface of the cup-shaped container. A cup-shaped container is fitted into the cup-shaped container, and the gripping piece is brought into contact with the side surface of the cup-shaped container. In this state, if the cup-shaped container is gripped from above the gripping piece under the flange-shaped plate portion, it can be gripped without feeling heat due to the heat insulating property of the gripping piece made of a heat insulating sheet material. Further, in this gripping state, the flange-shaped plate portion on the gripping piece is locked onto the finger gripped, so that even if the gripping force is slightly loosened, it can be gripped stably without fear of dropping off. Moreover, since the container load containing the contents is received by the entire inner periphery of the flange-shaped plate portion, an excessively strong force is not applied to the connecting portion between the gripping piece and the flange-shaped plate portion, In this gripping state, the gripping piece is not easily broken.

  In addition, this cup holder uses the inner plate portion inside the flange-shaped plate portion fitted to the outer periphery of the side surface of the cup-shaped container as a gripping piece, so that the protruding portion outward from the flange-shaped plate portion is used. There is no need to provide it, and it can be formed more compactly than the conventional product provided with a portion protruding outward, and the use area of the heat insulating sheet material for one holder can be small.

  In the cup holder, along the inner periphery of the flange-shaped plate portion, two incisions are formed to face each other so that the connecting portions remain at the opposite portions in the circumferential direction, and the inner plate The portion is divided into two in the middle between the two connecting portions, and both divided portions are formed as two gripping pieces connected to the flange-like plate portion so as to be bent via the connecting portions. preferable. As a result, two relatively large gripping pieces are formed to face each other, so that the cup-shaped container can be gripped stably and safely via both gripping pieces.

  In the cup holder, the inner plate portion is preferably formed by being divided into a plurality of divisional notches that pass through the center and reach each incision between adjacent connecting portions. The piece can be formed in a well-balanced manner.

  In the cup holder, it is preferable that both ends of each of the cuts along the inner periphery of the flange-shaped plate portion bend inward and terminate. As a result, when the gripping piece is bent, it is rounded and the bending width is increased. Therefore, when the flange-shaped plate portion is fitted to the cup-shaped container, the connecting portion is elastically attached to the side surface of the container. Sliding is less likely to occur due to the contact, and breakage from the end of the cut is less likely to occur.

  If the crease line is formed between the end portions of the cuts on both sides in each connecting portion, the connecting portion can be easily bent during use.

  In each of the cup holders described above, each gripping piece is formed with two parallel crease lines extending from the end of each notch on both sides of each connecting portion to the split notch. Can do. As a result, in a state where the gripping pieces are bent downward with respect to the flange-shaped plate portion, both side portions of the gripping pieces are slightly bent outward from the crease line, thereby forming a concave shape. This makes it easier to align the fingertip with the central portion of the gripping piece, making it easier to grip the cup-shaped container.

  Furthermore, in the cup holder of each of the above inventions, the incision along the inner periphery of the flange-shaped plate portion is formed so as to protrude inward at an intermediate portion in the circumferential direction, and the inner peripheral edge of the flange-shaped plate portion. If the portion has an inward protruding shape, the protruding portion comes into strong contact with the side surface of the cup-shaped container to increase the anti-slip effect. Therefore, the cup holder is attached to the cup-shaped container. Can be fitted with good stability, the feeling of holding can be further improved, and the cup holder does not fall when the cup-shaped container is placed on a table or the like.

  According to the cup holder of the present invention, the inner plate portion is used as a gripping piece for gripping the container from the annular flange-shaped plate portion fitted to the side surface of the cup-shaped container. It can be formed more compactly than conventional products with protruding parts, and the area of heat insulating sheet material for one holder can be reduced, and the number of parts taken from one heat insulating sheet material in production is increased accordingly. Can be manufactured easily and at a low cost.

  Further, in the use of this cup holder, the cup-shaped container can be stably and safely gripped from above the gripping piece under the flange-shaped plate portion fitted to the cup-shaped container. Therefore, it can sufficiently serve as a heat-insulating cup holder that avoids heat and the like with a minimum area.

  Next, embodiments of the present invention will be described based on examples shown in the drawings.

  FIG. 1 is a plan view showing an embodiment of a cup holder of the present invention, FIG. 2 is a perspective view of a state in which a grip piece by an inner plate portion is bent downward, and FIG. 3 is a grip with a cup-shaped container fitted. FIG. FIG. 4 is a plan view of a cup holder according to another embodiment, and FIG. 5 is a perspective view of a state in which a grip piece of the cup holder is bent downward.

  The cup holder A of the embodiment shown in FIGS. 1 to 3 is mainly used for a cup-shaped container C having a circular shape with a larger diameter on the upper end opening side. An example is shown in which, as a single heat-insulating sheet material having a moderate resistance to bending, for example, a synthetic resin foam sheet is integrally formed by means such as punching. The cup holder A of this embodiment basically includes an annular flange-shaped plate portion 1 that can be fitted to an intermediate portion on the oblique side surface c1 of the cup-shaped container C, and an inner periphery of the flange-shaped plate portion 1. It consists of at least two pieces for gripping 2a, 2a connected.

  The outer shape of the flange-shaped plate portion 1 is not limited to a circular shape as shown in the figure, but may be a substantially polygonal shape such as a quadrangle with rounded corners. The inner shape of the flange-shaped plate portion 1 is a shape corresponding to the side surface c1 of the cup-shaped container C, that is, mainly a substantially circular shape. The inner diameter of the flange-shaped plate portion 1 depends on the size of the cup-shaped container C to be used and the amount of contents, for example, a position above the center of gravity of the container containing the contents, for example, an intermediate part on the side of the container, preferably It is set so as to be fitted at a height position slightly higher than ½ of the container height from the bottom surface, more preferably at a height position of 6/10 to 7/10 of the container height from the bottom surface. Further, the outer diameter of the flange-shaped plate portion 1 is appropriately set in consideration of the shape retention by the flange-shaped plate portion 1 and the strength during use. For example, the radial width of the flange-shaped plate portion 1 is set to be about 10 to 15 mm.

  In the cup holder A, the flange-shaped plate portion 1 has the connecting portions 3 and 3 having a required width remaining at a plurality of locations along the inner periphery 1a at required intervals in the circumferential direction (mainly equiangular intervals). The inner plate portion 2 is defined by a plurality of cuts 4 and 4 that are formed, and the inner plate portion 2 is divided into a plurality of portions that are continuous with the connecting portions 3 and 3. The portions are formed as a plurality of gripping pieces 2a and 2a that are foldably connected to the flange-like plate portion 1 at the connecting portions 3 and 3, respectively, and the gripping pieces 2a and 2a are directed downward. In a state where the flange-shaped plate part 1 is fitted to the cup-shaped container C by bending, the cup-shaped container from above the gripping pieces 2a and 2a that come into contact with the container side surface c1 under the flange-shaped plate part 1 It is comprised so that C can be hold | gripped.

  In the embodiment shown in the drawing, the connecting portions 3 and 3 are left at the portions opposed to each other by 180 ° along the circle on the inner periphery 1a of the flange-shaped plate portion 1 so that the two circular arc-shaped cuts 4 and 4 are relative to each other. The inner plate 2 defined by the cuts 3 and 3 and defined by the flange-shaped plate 1 is an intermediate portion between the connecting portions 3 and 3, preferably the inner plate 2 Are divided into two symmetrically by the dividing notches 5 extending to the two notches 3 and 3, and both divided portions are connected to the flange-shaped plate portion 1 with the connecting portions 3 and 3, respectively. Are formed as two gripping pieces 2a, 2a which are connected so as to be bendable.

  The incisions 4 and 4 along the inner periphery 1a of the flange-shaped plate portion 1 are terminated by bending the both end portions 4a and 4a so as to be rounded inward, and the two gripping pieces 2a and 2a It is possible to prevent weakening of the connecting parts 3 and 3 due to bending and damage from the ends 4a and 4a of the cuts 4 and 4. Further, since the end portion 4a of the notch 4 is bent inwardly and terminates, even if the connecting portion 3 is bent inside the inner periphery of the flange-like plate portion 1, the heat insulation of the material is performed. If the conductive sheet material is a synthetic resin foam sheet that can be elastically deformed, the bending position of the connecting portion 3 is compared to the position on the inner circumference circle by fitting the flange-shaped plate portion 1 to the cup-shaped container C. It can be easily expanded and deformed along the side of the container.

  The connecting portions 3 and 3 may be formed with crease lines (not shown) for facilitating the bending of thinned recesses or the like, if necessary. The width of the connecting portions 3 and 3, that is, the width between the cut end portions 4 a and 4 a on both sides varies depending on the inner diameter of the flange-shaped plate portion 1 and the shape of the gripping piece 2 a. , And considering the ease of deformation at the time of fitting the cup-shaped container C, etc., can be set as appropriate, for example, in the range of about 10 to 25 mm.

  The notches 4 and 4 are formed so as to project inwardly in the middle part in the circumferential direction, and a part of the inner circumference 1a of the flange-like plate portion 1 projects inwardly. When the flange-shaped plate portion 1 is fitted to the cup-shaped container C, a frictional resistance is given by the projecting portions 1b and 1b, and it can be held at a predetermined fitting position and a feeling of holding is improved. It can be done. A plurality of the projecting portions 1b, 1b formed by projecting inward of the cuts 4, 4 can be provided for each of the cuts 4, 4, and the number and size thereof can be arbitrarily set. In the case of the figure, the dividing notch 5 is formed between the protrusions 1b, 1b at corresponding positions.

  The cup holder A of the second embodiment shown in FIGS. 4 and 5 is punched by using, for example, a paper material such as single-sided cardboard as a heat-insulating sheet material having heat-insulating properties and resistance to bending moderately. The example at the time of integrally forming by such means is shown. The basic structure of the cup holder A of this embodiment is the same as that of the above-described embodiment, and the annular flange-shaped plate portion 1 is connected to the opposing portions along the inner circumference 1a thereof. The arc-shaped cuts 4 and 4 formed so as to remain are defined as the inner plate portion 2 and the inner plate portion 2 passes through the center thereof and between the connecting portions 3 and 3. In the middle, the split notch 5 reaching both the notches 4 and 4 is formed and divided into two, and both split portions are formed as symmetrical gripping pieces 2a and 2a in common with the above-described embodiment. Yes. The dimensions of each part can be set in the same manner as described above.

  In the case of the cup holder A of this embodiment, both end portions of the notches 4 and 4 along the inner periphery of the flange-like plate portion 1 are slightly bent outward and terminated, so that the connecting portions 3 and 3 , A crease line 6 is formed on the line connecting the ends 4a, 4a of the cuts 4, 4 on both sides, so that the gripping pieces 2a, 2a can be easily bent during use. The crease line 6 is formed so as to be located on a tangent line of the inner periphery 1a of the flange-shaped plate portion 1. Such a crease line 6 is particularly suitable when the constituent heat insulating sheet material is made of a paper material such as single-sided cardboard.

  Each of the gripping pieces 2a, 2a has two parallel crease lines 7, 7 extending from both ends of the notches 4, 4 on both sides of the connecting portions 3, 3 to the middle dividing notch 5. It is formed, and in use, both end portions of the gripping pieces 2a, 2a can be bent inwardly as shown in FIG.

  The two fold lines 7 and 7 can be formed on the cup holder of the embodiment shown in FIGS. Also in the case of the embodiment shown in FIGS. 4 and 5, a part of the notches 4 and 4 are formed to project inward, and a part of the inner periphery 1a of the flange-like plate part 1 is inward. It is possible to increase the anti-slip effect when the flange-shaped plate portion 1 is fitted to the cup-shaped container C, and to increase the hold feeling.

  Furthermore, in any of the above-described embodiments, the cuts 4 and 4 and the dividing cut 5 along the inner periphery of the flange-shaped plate portion 1 are not necessarily completely separated, and are not used. In this case, it is also possible to implement a perforated cut (not shown) that can be easily cut off with a fingertip.

  In addition to the above, although the present invention is not illustrated in addition to the above, the inner plate portion 2 is connected to each connecting portion by providing three or more cuts 4 and connecting portions 3 along the inner periphery 1a of the flange-like plate portion 1. It can also be carried out by dividing each piece by dividing notches and forming each divided portion as three or more gripping pieces.

  As a heat insulating sheet material as a constituent material of the cup holder A, it has a heat insulating property such as a foamed sheet of synthetic resin or a single-sided cardboard and is moderately elastic, that is, moderately resistant to bending. A sheet material can be used. Among these, as a synthetic resin foam sheet, a polyolefin resin such as a copolymer mainly composed of polyethylene, polypropylene and polyolefin, a polystyrene resin, a polyester resin and the like are foamed at a relatively low magnification (2 to 60 times). A foamed sheet is preferably used. As for the thickness of this foam sheet, those having a thickness of 1.0 to 2.0 mm are suitably used. Of course, depending on the material, those outside the above range can also be used. Moreover, depending on the case, the foam sheet which laminated | stacked the non-foamed resin film on the at least single side | surface can also be used.

  In addition, as the sheet material made of paper having heat insulation properties, a paper material having heat insulation properties such as single-sided cardboard or corrugated cardboard having a small core peak can be used.

  In order to manufacture the cup holder A of the present invention from these sheet materials, the outer shape of the flange-shaped plate portion is die-cut by a punching blade die having a punching blade corresponding to the shape of the cup holder A described above, and At the same time, the cuts 4 and 4 along the inner periphery of the flange-shaped plate portion 1 and the dividing cut 5 of the inner plate portion 2 are formed by cutting. At this time, since it is not necessary to provide an extra protruding portion outside the flange-shaped plate portion 1, the area occupied by one holder can be small, and therefore, the holder extraction position in one heat insulating sheet material. Can be increased as compared with a conventional product having a protruding portion for gripping outside the flange-shaped plate portion. In particular, the number of picking positions of the circular cup holders can be increased in a staggered manner, for example, so that the die can be formed efficiently and manufactured at low cost.

  In use, the cup holder A manufactured in this manner is provided with connecting pieces 2a and 2a made of the inner plate portion 2 inside the flange-shaped plate portion 1 as shown in FIG. 2 or FIG. For example, the cup-shaped container C that accommodates a hot drink is fitted to an intermediate portion of the container height from below. Preferably, it is fitted at a height position slightly above 1/2 of the container height.

  Thus, the cup-shaped container C may be gripped from above the gripping pieces 2a and 2a under the flange-shaped plate portion 1 fitted to the side of the container, and the cup holder A made of the heat insulating sheet material 10 is gripped. The cup-shaped container C can be safely and stably gripped by interposing the pieces 2a, 2a as heat insulating layers. In particular, in the gripping state, the flange-like plate portion 1 on the gripping pieces 2a, 2a will be locked on the finger gripped, so that even if the gripping force is slightly loosened, it will become entangled. It can be held with good stability. Moreover, since the load of the container C containing the contents is received by the inner periphery 1a of the flange-shaped plate portion 1, the connecting portions 3, 3 between the gripping pieces 2a, 2a and the flange-shaped plate portion 1 A strong force is not applied, and there is no fear that the connecting portions 3 and 3 are torn.

  1 to 3, when both end portions 4a and 4a of the cuts 4 and 4 are bent inwardly, and when the gripping pieces 2a and 2a are bent, When the bending width is increased and the flange-shaped plate portion 1 is fitted into the cup-shaped container C, the connecting portions 3 and 3 are elastically brought into contact with the container side surface c1, and slipping is less likely to occur. The cuts 4 and 4 are hardly damaged from the end portions 4a and 4a, and can be used more safely.

  INDUSTRIAL APPLICABILITY The present invention can be suitably used as a cup holder when a cup-shaped container for serving a drink in a fast food store or in various vehicles or in a machine is made of paper, plastic, glass or the like.
