Description

  TECHNICAL FIELD The present invention relates to a cup-shaped container, and more particularly to an instant food that can be heated and eaten, and more particularly to a cup-shaped container that is optimal for packaging of instant food that can be eaten and drink by pouring hot water or heating in a microwave oven.

In recent years, instant ramen, miso soup, coffee, soup, tea, and other containers that can be eaten and consumed by pouring hot water into the container, or a cooked food container that is heated and eaten with the container in a microwave oven, are mainly cup-shaped. Containers (hereinafter simply referred to as paper cup-shaped containers) have been frequently used. This kind of container is provided with a heat insulation measure to protect the finger gripping the container from the heat of the contents during eating and drinking. As a conventionally known heat insulation measure, a paper substrate is laminated or impregnated with a thermoplastic resin and foamed, and a double wall structure is provided by providing a sack on the outer periphery of the container body (inner cup). An air layer provided between the sack and the container body (for example, see Patent Documents 1, 2, and 3), or a handle piece that becomes a handle when raised on the outer periphery of the container (for example, see Patent Document 4) )It has been known.
Japanese Patent Laid-Open No. 4-201840 JP 2000-28145 A Japanese Patent No. 3252478 Japanese Utility Model Publication No. 3-23011

  Of the above heat insulation treatments, those with foam treatment have a low heat insulation effect, and when hot water is poured, they feel very hot when gripped with bare hands, and those with a double wall structure and an air layer are generally foamed The heat insulation effect is high compared to the treated one, but even if such a heat treatment is performed, the outer surface of the container reaches 65 ° C to 75 ° C, it feels hot when held with bare hands, and the heat insulation effect is still not satisfactory Absent. In addition, a double-wall structure with an air layer inside requires the formation of a space in the wall thickness direction, so that a corrugated core or spacer is provided inside, or the sack itself has curls and complicated ruled lines. Is formed into a three-dimensional shape that is inflated to the outside, which inevitably increases the body wall of the container, increases the volume, and increases the bulk transportation cost and storage cost for storing products such as boxing. It is disadvantageous. In addition, when filling the contents into the container, empty containers are cut out and supplied from the lower part in a cylindrical state, but if there is an air layer on the body wall, the elasticity will increase on the body wall. In this state, due to the weight of the upper cup, the meshing between the containers becomes strong, and the container cut-out property is deteriorated. Further, providing the handle piece on the outer peripheral portion of the body of the container has a drawback that the handle piece becomes an obstacle and hinders stackability and cut-out property of the empty container.

  Furthermore, this type of conventional container is not limited to a heat insulating container, and the body wall is fixed to a predetermined shape and state, and the wall structure of the outer peripheral surface does not change during use, and changes and playability are possible. Is lacking. Therefore, for example, there was no additional effect such as pouring hot water and giving pleasure while waiting for the contents to be eaten. In addition, this type of conventional container has been subjected to various improvements as described above based on the technical idea of heat insulation and heat retention. However, for example, in the case of cup ramen, it is desirable that the container has a high heat retaining property for a predetermined time until the noodles can be eaten by pouring hot water in order to enhance the heating effect. When doing so, the part to be gripped by hand is required to have heat insulation, but the container as a whole is rather not heat retaining, and it is desirable to have a high heat dissipation effect so that the ramen to eat can be quickly cooled. However, a container based on such a concept has not been provided yet.

  Therefore, the present invention intends to solve the technical problems of the cup-shaped container applied to the above-mentioned application at a stroke, and it is not necessary to form an air layer in the middle, and it is not bulky even with a double wall structure. And the cup-shaped container that has good container-cutting property, is rich in unexpectedness such as change and playability, and has excellent heat insulation in the part to be gripped by hand when eating, and other parts have excellent heat dissipation The purpose is to provide.

  As a result of various studies to solve the above-mentioned problems, the present inventor does not always need to have a heat insulating structure for the container, and the portion held by hand at the stage of actual use (eat) has a heat insulating effect intensively. If it is high, and the body wall does not have a special heat insulation effect at the distribution stage, it is possible to make the body thin, and in use, the grip part of the body is insulated by the consumer. If it can be changed, it has been found that the container can have unexpectedness and change, and the present invention has been achieved.

  That is, the cup-shaped container of the present invention that solves the above problems comprises a cup-shaped container body and a sleeve that is attached by winding a sheet around the outer periphery of the body of the container body. It has a line-shaped adhesive part, a vertical zipper part, and a folding ruled line, and the sleeve is broken in the vertical direction from the zipper part, so that the base end part is developed on two wing pieces bonded to the container body. The blade piece is bent along the ruled line to form a container gripping portion.

  The sleeve is cut from the zipper when the zipper is provided at two locations so as to be located at substantially symmetrical positions in the circumferential direction, and two adhesive portions are provided adjacent to the zipper. Thus, two wing pieces are deployed at the target position, and the wing pieces are folded back along the ruled lines, thereby obtaining a container in which a triple structure gripping part and a single structure heat radiation part are formed. Further, as another configuration, when configured to have one streak-like adhesive portion and one zipper portion provided on the opposite side of the adhesive portion, the adhesive is obtained by breaking the zipper portion. A pair of wing pieces are formed on both sides of the part, the pair of wing pieces are folded back to each other to form a handle and a single heat dissipation part, and the handle is held and held by a container A cup-shaped container is obtained.

  By foaming the sleeve, it is possible to obtain a container in which the heat insulation during cooking (heating) is improved and the heat insulating effect of the gripping part when eating is further increased. Further, by breaking and folding the sleeve from the zipper portion, a line drawing having an additional function is printed on the outer peripheral wall portion of the exposed container body or the back surface of the sleeve, thereby obtaining a cup-shaped container with higher added value. .

  According to the present invention, since it is not necessary to form the body wall in a heat-insulating manner at the normal distribution stage, it is not necessary to form an air layer in the middle even in the double wall structure, and the container outer peripheral surface is not bulky. Can be formed on a uniform surface, has good container stackability and container cut-out properties, and has excellent unexpectedness such as change and playability. In this part, a packaging container with increased heat dissipation can be obtained. In particular, according to the present invention, when eating, more than half of the outer peripheral wall of the container body is exposed to the outside, so the heat dissipation effect is high. Furthermore, according to the configuration of the second aspect, the consumer can easily configure the gripping portion of the triple wall by breaking the sleeve from the zipper portion and folding it back along the opposite side at the time of use. Heat insulation can be effectively secured. According to the third aspect of the present invention, the consumer can easily form a large three-dimensional handle by breaking the sleeve from the zipper portion and folding it back along the ruled line at the time of use. As a result, a container rich in variability and design that is not found in conventional containers can be obtained. Furthermore, by breaking the sleeve during use and turning it over, the outer peripheral wall surface of the container body is greatly exposed, enhancing the heat dissipation effect, and cooking recipes, hidden information and forklifts on the exposed outer peripheral surface of the container body or the back surface of the sleeve, Fortune-telling or printing characters, etc., will increase the additional functions and provide a container that consumers can enjoy at the time of use.

  FIG. 1 shows an embodiment of a packaging container according to an embodiment of the present invention, and this embodiment is applied to a cup-shaped paper container. Here, the paper container is not necessarily limited to the one formed only of the paper material, the paper material laminated with the synthetic resin film, the paper material impregnated with the synthetic resin, or the paper material. This refers to containers made mainly of paper, such as those laminated with synthetic resin film and metal foil. The cup-shaped container is a container having a body wall and a bottom wall, and the size, depth, and body shape are not particularly limited. In the following embodiments, an example of a paper cup-shaped container is shown. However, the cup-shaped container body is not necessarily limited to a paper container, and a synthetic resin molded container can also be applied, and a sleeve surrounding the outer peripheral surface is also made of paper. Not only the product but also a synthetic resin film or a composite film can be used.

  The cup-shaped paper container 1 of the present embodiment (first embodiment) is formed of a cup-shaped container body 2 having a barrel wall 3 and a bottom wall 4 whose inner surfaces are water-resistant processed, and a sleeve 5. A sleeve 5 is fitted on the outer peripheral portion of the part wall 3 so as to cover the whole. The sleeve 5 is a sheet material whose base material is paper such as paper or synthetic resin laminated paper, and is formed in a cylindrical shape along the outer peripheral surface of the body wall of the container body. The sleeve 5 preferably has an upper end positioned near the upper end of the trunk wall and extends so that the lower end covers the lower end of the foot of the trunk wall. The lower end does not necessarily reach that position.

  The sleeve 5 is formed by forming a fan-shaped sheet into a cylindrical shape as shown in FIG. A joining margin part 6 is provided at one end edge, a first adhesive part 7 to the container body is provided at the other end part, and a second adhesive part 8 is provided at the center part. Both the first adhesive portion 7 and the second adhesive portion 8 are formed in a streak shape having a predetermined width from the upper end to the lower end of the trunk portion. And the 1st zipper part 9 and the 2nd zipper part 10 are provided adjacent to one side of the 1st adhesion part and the 2nd adhesion part, respectively. The zipper part is provided with a pair of intermittent cut lines 11 at a predetermined interval, and can be broken along the cut lines. Reference numeral 12 denotes a folding ruled line provided at a substantially middle part between the first zipper part 9 and the second adhesive part 8, and reference numeral 13 denotes a substantially middle part between the second zipper part 10 and the joining margin part 6 (second adhesive part). Folding ruled lines provided in the section, and these folding ruled lines may be either for valley folding or for mountain folding. Reference numeral 14 denotes a locking arc cut line provided to lock the edge of the folded wing piece when the zipper is broken and the wing piece is folded along the folding ruled line, as will be described later. Yes, it is provided so as to protrude from a substantially central part on one end side of the joining margin part 6 and the second adhesive part. However, it is not always necessary to provide the locking arc cutting line. In the sleeve 5 having the above-described shape, the first adhesive portion 7 and the second adhesive portion 8 are bonded in a vertical streak pattern to the outer peripheral portion of the body wall 3 of the container body 2, and the glue margin portion 6 is connected to the first margin portion 6. Attached to the adhesive part. As a result, the paper cup-shaped container 1 of the present embodiment has an outer shape as shown in FIG. As will be described later, the additional function may be appropriately printed on the outer peripheral surface of the trunk wall 3 of the container body or the back surface of the sleeve exposed by breaking the sleeve 5 from the zipper portions 9 and 10 and turning it back.

  In the container formed as described above, as shown in FIGS. 1 (a) and 1 (b), the body is generally a double wall of the body wall 3 and the sleeve 5 of the container body. Since there is no space such as an air layer in the container, the body wall and the sleeve of the container body are in direct contact with each other, the thickness is not so large and the storage volume can be reduced, and the body walls are fitted together. In the stacked state, the stacking property and the cutting property are good as compared with the conventional heat insulating container of this type. From this state, when eating the contents, for example, before pouring hot water inside or when eating, as shown in FIG. 3 (a), by breaking the first zipper part 9 and the second zipper part 10, The sleeve 5 is divided into two wing pieces 15 and 16 which are bonded to the first bonding portion 7 and the second bonding portion, respectively, whose base portions are located at the target positions, and separated from the body wall 3 of the container body except for the bonding base portion. It will be in the state. Next, as shown in FIGS. 4B and 4C, the wing pieces 15 and 16 are bent from the folding ruled lines 12 and 13, so that the folded portion becomes a container as shown in FIG. Together with the body wall 3 of the main body, a triple wall is formed. At that time, the blade edges 15 and 16 are engaged with each other by inserting the fracture side edges of the blades 15 and 16 into a semicircular disk-shaped locking portion 14 with the locking arc cutting lines 14. Can be held in a bent state. If the wing piece is folded inward from the folding ruled line in the opposite direction to that shown in FIG. 3 (b), the folded-back side portion can be folded under the bonded portion-side side portion. Even if not locked, the bent state is maintained.

  Therefore, by gripping the folded wing pieces 15 and 16 as the gripping portion 19, the heat insulating effect of the gripping portion 19 is enhanced, and even with the contents poured with hot water, the container can be held with bare hands without feeling too much heat. It can be gripped. On the other hand, by folding the wing pieces twice, about half of the outer periphery of the barrel wall 3 of the container body is exposed to the outside, and that portion is only the barrel wall as shown in FIG. Compared with the state of FIG. 1, the heat radiation from that portion is increased, and the heat radiation effect is enhanced.

  Therefore, when holding the container and eating the contents directly from the container, the transmission of heat to the finger is weak, it can be held without feeling the heat, and on the other hand, the heat dissipation effect at parts other than the grip part is high It cools quickly to the optimal temperature for eating, allowing you to eat comfortably. And, in a state where the wing piece is bent, about half of the trunk wall 3 of the container main body that was not surrounded by the sleeve in FIG. 1 is exposed and becomes a single wall state. Printing cooking recipes, hidden information, fortune-telling, fortune-telling, cartoons, characters, etc. can provide time consumers with the pleasure of watching the contents, and innovative changes in sleeve shape In addition, it is possible to provide a container that is rich in playability. In addition, the heat insulation effect can be improved by subjecting the sleeve to foaming treatment. In addition, when it is desirable that the container body has a high heat retaining property, the heat retaining property can be increased by foaming the body wall of the container body in the same manner.

  5 to 6 show a paper container according to a second embodiment of the present invention. The paper container 20 of the present embodiment is a modification of the paper container of the first embodiment, and the same parts are denoted by the same reference numerals, and only differences will be described. The main difference between this embodiment and 1st Embodiment is a point which forms a handle with a blade piece and comprises a holding part as a handle. FIG. 6 is a development view of the sleeve 21. In the figure, a broken line in the sector represents a folding ruled line, and a solid line represents a cut line. In the present embodiment, the sleeve 21 is formed so as to be bonded to the body wall 3 of the container main body by only one bonding portion 22 formed only at one end of the sleeve, and along the inner side of the bonding portion 22. A second ruled line 25 is formed along the first ruled line 24 and the margin part 23 at the other end.

  A zipper portion 26 formed by a pair of cut lines 38 is provided at an intermediate portion between the first ruled line 24 and the second ruled line 25. Accordingly, by bonding the sleeve to the outer periphery of the body wall of the container main body and bonding the glue margin 23 to the upper surface of the adhesive section, as shown in FIG. Can be covered with a sleeve 21. In this state, the sleeve is separated into the first wing piece 27 and the second wing piece 28 on both sides of the adhesive portion as shown in FIGS. 5B and 5C by breaking and removing the zipper portion. can do. A slit and a ruled line for forming a handle 29 as shown in FIG. That is, as clearly shown in FIG. 6, each wing piece 27, 28 is formed with a pair of ruled lines 30 defining the outermost thickness of the vertical edge 32 of the handle at the center thereof, and on both sides of the ruled line, respectively. A pair of longitudinal slits 33 for forming the finger holes 31 of the handle and a lateral slit 34 connecting the center portions thereof are formed. Then, horizontal ruled lines 35 and 36 are formed by connecting the upper and lower ends of the pair of vertical slits 33 and 33. Therefore, the portion surrounded by the slit becomes the tongue piece 37, and the finger holes 31 can be formed by bending up and down along the upper and lower ruled lines 35 and 36. In the present embodiment, the finger holes 31 include the adhesive portion side finger holes 31a and the zipper side finger holes 31b of the first wing piece 27, and the adhesive portion (paste margin) side finger holes 31c and the zipper side of the second wing piece 28. With the combination of the finger holes 31d and the handle 29 formed as shown in FIG. 5D, the adhesive portion side finger holes 31a of the first wing piece 27 and the zipper side finger holes 31c of the second wing piece 28 are formed. Are formed symmetrically so that the zipper side finger hole 31b of the first wing piece 27 and the adhesion part side finger hole 31d of the second wing piece 28 overlap each other. However, the shape and configuration of the finger holes are not limited to those of the above embodiment, and various forms can be employed.

  The paper container 20 of the present embodiment is configured as described above, and when used, the zipper part 26 is broken in the same manner as in the previous embodiment, whereby the sleeve 21 is centered on the adhesive part 22 and the two wing pieces 27 are formed. , 28. Then, both wing pieces are folded along the ruled lines 24 and 25 opposite to each other and overlapped, and the respective wing pieces 27 and 28 are bent from the pair of ruled lines 30, whereby the first wing piece 27 has finger holes on the bonding portion side. 31a and the zipper side finger hole 31c of the 2nd wing piece 28 overlap, and the zipper side finger hole 31b of the 1st wing piece and the adhesion part side finger hole 31d of the 2nd wing piece 28 overlap, respectively. In this state, the tongue pieces formed by the slits are pushed inward at the positions of the finger holes to form the finger holes 31 as shown in FIG. 5 (d), and a cup-shaped container with a handle is obtained. It is done.

  Therefore, at the time of use such as eating the contents, the container 29 can be grasped with bare hands without feeling the heat even if the contents are poured with hot water by grasping the handle 29. On the other hand, by forming the handle 29 by folding the wing piece, many parts of the trunk wall 3 of the container body 2 are exposed, and that part becomes a single wall only of the trunk wall, Increases heat dissipation from the part. Therefore, a container having a further excellent heat dissipation effect during use can be obtained, and the exposed area of the outer peripheral surface of the body wall of the container main body can be increased so that the portion can be used more effectively as a display surface.

  Although the embodiment of the present invention has been described above, the cup-shaped container of the present invention is not limited to the above embodiment, and various design changes can be made. For example, in the above-described embodiment, the folding ruled line is formed in the vertical direction in parallel with the body wall of the container body, but the ruled line may be formed obliquely in a diagonal shape of the wing piece. Further, the cut lines of the zipper part do not necessarily have to be formed in a pair, and may be formed by a single intermittent cut line. In addition, the arc cutting line for locking is formed to maintain the wing piece in the folded state. Instead of such means, the upper edge is placed on the upper edge of the portion that becomes the wing piece on the folded side of the sleeve. It is also possible to project a locking piece projecting upward from the base and to point the locking piece into a curled portion of the container body when the wing piece is folded back.

  The paper cup-like container of the present invention has no bulging part in the body part at the normal distribution stage, and a bulging part that becomes a gripping part is formed during use to enhance heat insulation, so that it is used for high-temperature storage with paper material. For instant foods that can be eaten and consumed by pouring hot water into the container, such as instant noodles, miso soup, coffee, soup, tea, etc. Not only can it be applied to packaging containers, it can also be used as a disposable cup for eating hot food. Moreover, it is applicable also to the container of the food and drink whose contents are cold.
