Description

  INDUSTRIAL APPLICABILITY The present invention relates to a cup-shaped container, more particularly an instant food that can be heated and eaten, and in particular, a cup-shaped cup suitable for a cup-shaped cup-shaped container that wraps instant food that can be consumed by pouring hot water or heating in a microwave oven. Concerning the container.

In recent years, paper is the main ingredient for instant ramen, miso soup, coffee, soup, tea, and other containers that can be eaten and consumed by pouring hot water into the container, or as a cup-shaped container for cooked food that is heated and eaten with the container in a microwave oven. A cup-shaped container (hereinafter simply referred to as a paper cup-shaped container) has been frequently used. This kind of container has heat insulation measures to protect the hand holding the container from the heat of the contents during eating and drinking. As a conventionally known heat insulation measure, the surface of a paper base material is laminated or impregnated with a thermoplastic resin and subjected to foaming treatment. A structure having a heavy wall structure in which an air layer is provided between the sac and the container main body (for example, see Patent Documents 1, 2, and 3), or a structure in which a handle piece that becomes a handle when connected to the outer periphery of the container is connected (for example, Patent Document 4) is known.
Japanese Patent Laid-Open No. 4-201840 JP 2000-281455 A Japanese Patent No. 3252478 Japanese Utility Model Publication No. 3-23011

  Of the above heat insulation measures, those with foamed body walls have a low heat insulation effect, and when hot water is poured, they are felt very hot when gripped with bare hands, and those with a double wall structure and an air layer are provided. In general, the heat insulation effect is higher than that of foaming treatment, but even with such heat insulation treatment, the outer surface of the container reaches 65 ° C to 75 ° C, it feels very hot when held with bare hands, and the heat insulation effect is still satisfactory Not what you want. In addition, the double wall structure with an air layer in the interior requires the formation of a space in the wall thickness direction, and a corrugated core is provided in the interior, or a complicated ruled line is formed in the sac itself. Since the three-dimensional shape inflated is complicated, the manufacturing process is complicated, and the body wall of the container is inevitably thick, which increases the volume, which is disadvantageous for boxing of products. Furthermore, when filling the contents into the container, the empty container is cut out and supplied from the lower part in a cylindrical shape. However, if there is an air layer on the body wall, the body wall will become more elastic, In this state, due to the weight of the upper cup, the fitting between the containers becomes strong, and there is a disadvantage that the container cut-out property is deteriorated. In addition, the provision of the handle piece on the outer peripheral portion of the body wall of the container has a drawback that the handle piece becomes a hindrance and obstructs stackability and cut-out property of empty containers.

  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. In addition, this type of conventional container has been improved in various ways as described above from the viewpoint of improving heat insulation and heat retention. For example, in the case of cup ramen, noodles are eaten by pouring hot water. Even if a highly heat-insulating container is desirable in order to increase the heating effect, the predetermined time until softening is possible can be kept warm as a whole container if the part to be gripped by hand is insulated when eating. Rather, it is desirable to have a high heat dissipation effect so that the ramen to be eaten can be quickly eaten. However, a container based on such a concept has not been provided yet.

  Therefore, the present invention intends to solve the technical problem of the cup-shaped container applied to the above-mentioned use at once, and it is not necessary to form an air layer in the middle in the distribution stage, and has a double wall structure. Cups that are not bulky, have good cut-out properties, are rich in unexpectedness such as change and playability, and have excellent heat insulation when gripped by hand, while other portions increase heat dissipation. The purpose is to provide a container.

  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. It is sufficient if the body wall is high and it does not have a special heat insulating effect on the body wall in the distribution stage, and the body can be made thin. If it can be changed, it has been found that the container can have unexpectedness and changeability, and the present invention has been achieved.

  That is, the cup-shaped container of the present invention that solves the above problems has a container main body having a trunk wall and a bottom wall, and a sleeve fitted to the outer peripheral surface of the trunk wall of the container main body, and a substantially intermediate portion of the sleeve. A plurality of slits are formed in the vertical direction over the entire circumference of a certain range in the height direction, the middle portion of the body wall is divided into a plurality of strip pieces, a ruled line is put in the strip pieces, and the lower part of the sleeve is the container body The upper part including the strip is slidable downward along the barrel wall of the container body, and the strip is bent from the ruled line by sliding the sleeve. Thus, a gripping portion is formed.

The gripping portion has a configuration in which the strip is bent and has a quadruple wall or more including the barrel wall of the container body. A highly heat-insulating container can be obtained. As an example, by forming a horizontal mountain fold ruled line in a substantially middle portion of the strip, and forming a valley fold ruled line formed in parallel at a predetermined interval below the mountain fold ruled line, The gripping portion can be configured as a quadruple wall including the body wall of the container body. Further, if one or more of the strip pieces are used as handle strips without providing a ruled line in the middle portion, the handle strips bulge outwardly by sliding the sleeve downward, and the handle Can be formed. In that case, the container which can hold | grip only a handle or can hold | grip a quadruple wall structure part similarly to the above is obtained. When the handle is formed, the other strip pieces do not necessarily have a quadruple wall structure when used.

  Further, as another configuration for obtaining heat insulation of the gripping portion, the strip is slid downward to bend the strip piece and bulge outward, and an air layer is formed between the body wall of the container body. The structure can be formed. As an example, a first ruled line for valley fold inclined substantially 45 ° near the upper part of the strip, a second ruled line for mountain fold formed below and parallel to the first ruled line, and further below By providing a ruled line composed of a third ruled line for mountain folding and a fourth ruled line for valley folding formed symmetrically with the first ruled line and the second ruled line at a predetermined interval, the container has the container A trapezoid frustum-shaped air layer can be formed between the body wall and the body wall along the circumferential direction of the sleeve. When the sleeve is slid downward to form an air layer, the sleeve is locked at that position and the air layer is stably held. A horizontal folding ruled line connecting the vertical slits is formed, and a horizontal slit connecting the vertical slits is formed in the lower part, and can be folded upward from the horizontal folding ruled line. It is desirable to form a stopper tongue.

  By using the outer peripheral surface of the body wall of the container body that is exposed by sliding the sleeve downward as a display surface, a cup-shaped container that is more varied and interesting can be obtained.

  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 stackability and excisability, and has excellent unexpectedness such as change and playability. In this part, a cup-shaped container with increased heat dissipation can be obtained. In addition, when the consumer simply slides the sleeve downward, the sleeve is deformed along the ruled line to form a gripping portion, so that the gripping portion can be easily formed and the outer shape of the container is three-dimensionally changed. As a result, it is possible to obtain a container rich in variability and design that is not found in conventional containers. Furthermore, by sliding the sleeve, using the outer peripheral wall surface of the exposed container body as a display surface as in the configuration of claim 7, printing hidden information, fortune-telling, fortune-telling, characters, etc., A container that consumers can enjoy at the time of use is obtained.

  Furthermore, according to the structure of Claims 2-3, although a trunk | drum is a double wall, a grip part can be easily comprised in a quadruple wall at the time of use, and the heat insulation of a grip part is ensured effectively. it can. According to the fourth aspect of the present invention, the handle can be easily formed on the grip portion by simply sliding the sleeve downward during use. According to the configuration of the fifth to seventh aspects, the air layer can be easily formed on the grip portion by simply sliding the sleeve downward during use. A cup-shaped container having a uniform trapezoidal frustum-like shape in the direction and continuously appearing can be obtained, an air layer can be reliably ensured and the heat insulation is excellent and the design is excellent. Moreover, according to the structure of Claim 7, the state which slid the sleeve downward can be hold | maintained stably.

  FIG. 1 shows an embodiment of a cup-shaped container according to an embodiment of the present invention, and this embodiment is applied to a paper cup-shaped container. Here, the cup-shaped container is not necessarily limited to one formed only of paper material, but is a paper material laminated with a synthetic resin film, a paper material impregnated with a synthetic resin, or a 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, but the cup-shaped container body is not necessarily limited to a cup-shaped container, and a synthetic resin-molded container can be applied, and a sleeve surrounding the outer peripheral surface is also available. Not only paper but also a synthetic resin film or a composite film can be used.

  A cup-shaped cup-shaped 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. As shown in the present embodiment, the sleeve 5 is preferably positioned so that its upper end is located in the vicinity of the upper end of the torso wall and its lower end covers the lower end of the torso of the torso wall. The upper end portion and the lower end portion do not necessarily reach the positions.

  In the intermediate portion 11 of the sleeve 5, slits 7 having the same length are formed over the entire circumference at predetermined intervals in the vertical direction, and the slits are divided into a plurality of strip pieces 15. And as shown with a broken line in Fig.1 (a), the ruled lines 8 and 9 are given to the center part and lower end part of the strip piece 15 over the perimeter of a circumferential direction. Among these, the ruled line 8 is formed as a mountain fold ruled line, and the ruled line 9 is formed as a valley fold ruled line. The sleeve 5 thus formed has only the lower part 10 bonded to the body wall 3 of the container body from the ruled line 9, and the intermediate part 11 and the upper part 12 on which the strips 15 are formed are the container body. 2 is slidable.

  In the container formed as described above, as shown in FIG. 1, the body is usually a double wall of the body wall 3 and the sleeve 5 of the container body, but a space such as an air layer is provided in the middle. Since there is no part, the body wall of the container body and the sleeve are in direct contact with each other, and it is not so thick and bulky, and in a state where the body walls are fitted and stacked, Compared to stacking and cutting properties. Therefore, in a state in which the contents are filled and the opening is sealed with a lid member, the container is not bulky as compared with the conventional heat insulating container, and the accommodation property in the distribution stage such as boxing can be improved. From this state, when eating the contents, when the sleeve 5 is pushed downward with lightly grasping the upper part 12 of the sleeve 5 before pouring hot water inside, the intermediate part 11 not bonded to the container body, The upper part 12 slides freely downward. Since the sleeve 5 is formed with slits 7 in the vertical direction, the strips 15 formed between the slits are allowed to spread from the slit portion by being pushed down, and the strips 15 formed between the slits can be folded and folded from the middle ruled line 8. As shown in FIG. 2 (a), the bottom ruled line 9 is gradually bent into a valley fold, and as shown in FIG. When the part of the ruled line 8 is bent downward beyond the part of the ruled line 9, an urging force acts in that direction, and the bent state is maintained even if the hand is released. In this state, as shown in FIG. 4 (b), the gripping part 16 includes the container body trunk wall 3, the lower part 10 of the sleeve, the lower part wall 11-1 of the strip piece, and the upper wall 11-2 of the strip piece. This is a quadruple wall. Therefore, if this part is grasped with a finger, the transfer of the heat of the contents to the finger is weak, and it can be comfortably grasped without feeling the heat.

  In the state where the sleeve is lowered, the upper part of the body wall 3 of the container main body, which is not visible because the upper part of the sleeve is located in FIG. 1, is exposed and becomes a single wall state. The heat dissipation from the part increases, the temperature drop of the content is accelerated, and it can eat more comfortably. In addition, if the recipe, hidden information, fortune-telling, fortune-telling, cartoons, characters, etc. are printed in advance on the body wall of the container body that will be exposed when the sleeve 5 is lowered, the contents are heated. It is possible to provide the consumer with the pleasure of watching it, and to provide a container that is rich in playability as well as a novel change in sleeve shape. 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.

  3-5 has shown the cup-shaped container which concerns on the 2nd Embodiment of this invention. The cup-shaped container 20 of the present embodiment is a modification of the cup-shaped container of the first embodiment, and the same parts are denoted by the same reference numerals, and only differences will be described. The difference between the present embodiment and the first embodiment is that, among the strip pieces 15 formed by the slits, the strip pieces positioned at intervals of about 90 degrees are made longer than the other strip pieces and are used for the handle strips. No. 21, and the strip piece is formed so as to be a handle. That is, in FIG. 3, slits 22 on both sides of a portion where the four strip pieces 21 positioned at approximately 90 degrees are formed extending downward, and the other strip pieces 15 are formed in the middle portion of the strip pieces. A ruled line that is formed is not provided, and a ruled line 23 is provided only between the lower ends of the slits 22. Note that the ruled line 23 is not always necessary and can be omitted. In this configuration, by making the handle strips 21 longer than the other strips 15 as described above, a handle that is easy to grip can be formed. The handle can be formed with the same length. Further, the number of the strip pieces 21 for the handle is not limited to four, and may be one or two.

  The cup-shaped container 20 of the present embodiment is configured as described above, and when used, when the upper portion of the sleeve 5 is lightly pinched with a finger and pushed down, as shown in FIG. 5 is folded from the middle ruled line 8 in a mountain fold shape, but the handle strip 21 without the ruled line in the middle is curved outward and pushed down to the maximum position as shown in FIG. It will be in the state shown in FIG. Therefore, when eating or drinking, a finger is inserted into this part, or gripped with the finger and used as a handle, or the grip portion 16 that is a quadruple wall is gripped and used as in the above embodiment. You can also. Other functions and effects are the same as those of the above embodiment.

  FIGS. 6-7 has shown the cup-shaped container which concerns on the 3rd Embodiment of this invention. The paper cup-shaped container 30 of the present embodiment is different from the above-described embodiments in that the strips are bent, and an air layer is formed between the body wall of the container body by lowering the sleeve. It has become. In the present embodiment, the vertical slits 7 are formed at equal intervals on the entire circumference of the sleeve 31 in the same length as in the first embodiment, but four ruled lines are formed for each strip 32. Each ruled line is inclined by 45 °. In the figure, the first ruled line 33 is inclined 45 ° downward from the top of the slit and formed for valley folding, and the second ruled line 34 is formed for mountain folding parallel to the first ruled line 33 at a predetermined distance. ing. In addition, the third ruled line 35 is inclined from the lower end of the slit to be inclined 45 ° and formed for valley folding, and the fourth ruled line 36 is spaced from the third ruled line 35 by a predetermined distance (the first ruled line and the second ruled line). It is formed for mountain folding in parallel with the same interval). That is, the first ruled line, the second ruled line, the third ruled line, and the fourth ruled line are formed symmetrically. Other configurations are the same as those of the above-described embodiments.

  When the cup-shaped cup-shaped container 30 of the present embodiment configured as described above is used, when the upper portion of the sleeve 31 is gripped and slid downward, each strip piece 32 becomes a first ruled line 33 to 33. A grip portion 37 is formed by bending along the fourth ruled line 36 so that the strip bulges outward in a trapezoidal frustum shape. Since each strip is deformed into the same shape, as shown in FIG. 7, a band shape in which a trapezoidal frustum-shaped gripping portion 37 is continuously connected to the container body portion is exhibited, and three-dimensional decoration is enhanced. An air layer is formed between the outer peripheral wall 38 of the grip portion and the body wall 3 of the container body (that is, inside the grip portion), and the air layer includes the first ruled line and the second ruled line. Since it can be formed widely corresponding to the interval, the heat insulation effect is high. In the present embodiment, the air layer is formed by expanding the grip portion into a truncated cone shape, but the formation of the air layer is not limited to this shape. For example, the first to fourth ruled lines described above are used. Are formed parallel to each other in the circumferential direction, a quadrangular prism-shaped bulging portion can be formed, and a gripping portion bulging into various shapes can be formed depending on how the ruled lines are provided.

  The cup-shaped container 40 shown in FIGS. 8 and 9 is an improvement of the cup-shaped container 30 shown in FIGS. 6 to 7, and the same components are denoted by the same reference numerals and only different points will be described. The cup-shaped container 40 of the present embodiment is provided with the stopper tongue 41 so that when the sleeve 31 is slid downward to form an air layer, the state is easily maintained even if the hand is released. Features. The stopper tongue 41 is formed using a part of the strips 32 and is bent in the lateral direction to connect the longitudinal slits 7 to the upper part of the strips. A ruled line 43 is formed, and a horizontal slit 44 connecting the vertical slits is formed in the lower part, and the line can be folded upward from the horizontal folding ruled line 43. The stopper tongue 41 is folded upward while the sleeve is slid downward, and its tip is fitted and locked to the curl portion of the container body. It prevents you from doing it. Therefore, it is desirable that the stopper tongue 41 has a dimension that extends straight when bent and the tip of the stopper tongue 41 fits into the curled portion. The positions of the lateral folding ruler line 43 and the lateral slit 44 are adjusted so as to be the dimensions. What is necessary is just to select suitably.

  The cup-shaped container 40 of the present embodiment configured as described above is configured such that the stopper tongue 41 is folded back and inserted into the curled portion 6 of the container body as shown in FIG. 9 with the sleeve 31 pushed down during use. The sleeve can be prevented from returning to the original state. Therefore, even if the hand is released from the sleeve while the contents are being heated, the sleeve maintains the state shown in FIG. 9, and the grip portion where the air layer is formed can be gripped with peace of mind after heating. Moreover, since the trunk | drum wall 3 of a container main body is exposed in frame shape by folding back the stopper tongue piece 41, the container which is rich in taste can be obtained by printing information, such as forklifting, in this part beforehand. it can.

  The cup-shaped container of the present invention does not have a bulging part or the like in the body part in a normal distribution stage, and the bulging part is formed at the time of use to improve heat insulation, so that instant ramen can be eaten and consumed by pouring hot water into the container. It can be applied not only to containers for miso soup, coffee, soup, tea, etc., but also to cup-shaped containers for cooked foods that are heated and eaten with a microwave oven, and can also be used as disposable cups for eating hot food and drinks. Is expensive. Moreover, it is applicable also to the container of the food and drink whose contents are cold.
