Description

  The present invention relates to a packaging container capable of holding a small container smaller than the container main body, and more particularly to a packaging container having a small container holding structure adjacent to the container main body.

  Traditionally, retail stores such as supermarkets, convenience stores, and department stores have sold noodles such as buckwheat, udon, ramen, chilled Chinese, etc. in a predetermined packaging container (lunch format). Examples of such a lunch box type include a type in which juice is added to noodles in a packaging container and a type in which noodles are added to soup poured into a small container (cup) of the packaging container. In particular, the latter type is a menu that reflects Japan's unique food culture such as Morisoba and tsukemen, and there is room for improvement in packaging containers.

  For example, the idea which provided the through-hole which inserts and hold | maintains a cup for exclusive use of a soup is proposed in the inside dish also used as a cover body which plugs up the opening part of the cup-shaped container main body which arranges noodles (for example, patent documents 1) reference.). With such a structure, since the bottom portion of the cup for exclusive use of the soup held by the through hole is used in the hot water poured into the container body, the soup in the cup can be easily heated. That is, in order to heat the soup while holding the soup cup, the container body and the middle dish must be in two stages.

JP-A-9-99982

  However, according to the above-described idea of the prior art, not only the cup for exclusive use of the soup stock can be held without a removable intermediate dish, but also the noodles are difficult to eat unless the cup for exclusive use of the soup stock is removed from the intermediate dish. That is, the above concept cannot be adopted for a packaging container that does not have a detachable middle dish, for example, in order to solve a problem related to a packaging container that holds a small container such as a cup dedicated to soup with the container body. It cannot be applied to the suggestion.

  In a packaging container that holds a small container with the container body, for example, if the structure holds all of the circumferential direction of the small container, it may be difficult to attach or detach the small container, or the structure that holds the small container with respect to the container body Since the proportion of the occupancy is too large, the balance becomes poor, so it is difficult to eat food and the appearance may be deteriorated. In addition, if a food misplacement occurs and the container body protrudes and enters a structure that holds a small container, the small container may be crushed due to the small container being placed, resulting in poor quality and reduced product quality. There is a fear.

  In response to an unsolved problem in adopting a packaging container that holds such a small container with the container body, the inventors have a new structure based on a technical idea completely different from the conventional technique, after creative ingenuity. I came to development. In other words, in order to hold a small container in the container body, it may be the minimum necessary structure to prevent misalignment, and furthermore, a structure that combines food misplacement and consideration for meals is an essential element. The inventors have arrived.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a packaging container that combines the attachment / detachment of small containers, the arrangement of foods, and consideration of meals.

  In order to solve the above-mentioned problems, the packaging container according to the present invention is formed integrally with a small container holding part for placing a small container on a container main body for storing contents. Has a bottom portion and a peripheral wall portion that rises from the bottom portion so as to surround the circumferential direction of the small container, and the peripheral wall portion has a position adjacent to the container main body at a position that is approximately 1/5 to approximately 4 in the circumferential direction. It is characterized in that a cut-out part cut out by one part is formed.

  Moreover, it is desirable that the cutout portion is cut out so that the bottom portion and the container body are connected in a flush manner.

  Moreover, it is desirable that the bottom portion has a protruding portion that protrudes along the inner peripheral edge of the peripheral wall portion.

  Below, the definition of each requirement which comprises this invention, a meaning, or a specific example is shown.

  The location of the “small container holding part” may be, for example, a position that does not protrude outward (inside the container body) or a position that protrudes (outside the container body) with respect to the rectangular container body in plan view. In view of the predetermined dimensions of the container body, the inside of the container body is preferable.

  “Content” refers to food in general, and in particular, there is a menu for adding main foods to liquid (or semi-liquid) ingredients such as soy sauce, sauce, and soup, and applying these ingredients to the main food. Applicable, for example, noodles such as buckwheat, udon, ramen, chilled Chinese and pasta, rice such as curry and rice, baked fried rice, and side dishes such as steak, hamburger, tempura and salad.

  The “small container” is a container for storing food in general, and may be a container for storing the above-described liquid (or semi-liquid) ingredients. The shape of the “small container” may be, for example, a cylindrical shape, a bowl shape, a ball shape, or the like.

  The “position adjacent to the container main body” may mean that a notch is provided at a location where the inside of the container main body and the inside of the small container holding portion communicate. The width of the “notch” may be such that the placed small container is not displaced, and may be about 1/5 to about 1/4 with respect to the entire circumferential direction of the peripheral wall, preferably 1/5. It may be ˜1 / 4. If it is less than one-fifth, the width of the notch is too narrow and the container body and the small container holding part are substantially separated by the peripheral wall, and if it is more than a quarter, the width of the notch is too wide. This is because the position shifts.

  “So that the bottom and the container body are connected flush with each other” means that the bottom part of the small container holding part and the bottom part of the container body are formed on the same surface, and the bottom part is not separated by the peripheral wall part. It may mean that a notch is formed in In other words, a convex rib having a low height different from the peripheral wall portion or a concave recess having a shallow depth may be separately provided at a boundary portion between the bottom portion of the small container holding portion and the bottom portion of the container main body.

  The “projecting portion” may be, for example, a step projecting in a band shape higher than the bottom of the small container holding portion or a rib projecting partially. “Protruding along the inner peripheral edge of the peripheral wall” means that the bottom of the small container and the bottom of the small container holding part extend beyond the notch while the small container is placed on the protrusion. It may mean a structure in which a predetermined gap is generated between them. The height of the “projection” with respect to the bottom of the small container holding part may be 0.5 mm to 5 mm, preferably 1.5 mm to 4 mm, more preferably 2 mm to 3.5 mm. If it is less than 0.5 mm, it is too low and the small container may crush the contents, and if it is 5 mm or more, it may be too high and the contents may enter.

  The packaging container according to the present invention has a cutout in which a circumferential wall portion of a small container holding portion formed integrally with a container body is cut away from a position approximately adjacent to the container body in the circumferential direction by about 1/5 to about 1/4. By forming the portion, it is possible to expect the effect of placing the small container easily and not easily displaced. Furthermore, when the small container holding part is provided inside the container main body, an effect of ensuring a wider storage area for the contents with respect to the container main body by the notch part can be expected. That is, since a part of the peripheral wall part separating the container main body and the small container holding part is replaced with the notch part, the storage area of the contents of the container main body can be expanded to the small container holding part.

  In addition, since the notch is notched so that the bottom of the small container holding part and the container main body are flush with each other, if the small container is removed, the food in the container main body is placed on the bottom of the small container holding part. You can expect the effect to be spread and mixed. That is, when noodles such as buckwheat are hardened before eating, not only the chopsticks are rotated with respect to the noodles but also swayed in all directions so that the noodles are easily diffused and easily loosened.

  In addition, since the bottom portion of the small container holding portion has a protruding portion that protrudes along the inner peripheral edge of the peripheral wall portion, a gap is created between the bottom portion of the small container and the bottom portion of the small container holding portion when placed. Therefore, it can be expected that the foods and the like that are served will not be crushed even if they spread to the bottom of the small container holding part. For example, when noodles are arranged in line production, even if several of the noodles provided from the device have entered the small container holding part beyond the bottom of the container body, which is the original serving place, When the container is placed, the food in the small container holding part fits in the gap described above, and is not crushed and does not lose its shape, so that it can contribute to the maintenance of the appearance and the hygiene quality of the food.

The nearer side may be expressed as the near side, the far side as the rear side, the left hand direction as the left side, the right hand direction as the right side, the upper direction as the upper side, and the lower direction as the lower side.

  As shown in FIG. 1, the present packaging container is integrally formed with a small container holding part 1 for holding a small container in a container main body P for storing food. 11 and a peripheral wall portion 12 that rises from the bottom so as to surround the circumferential direction of the small container, and the peripheral wall portion is located at a position adjacent to the container body in the circumferential direction from 1/5 to 1/4. A cutout portion 13 that is cut out may be formed.

  Moreover, the notch part 13 may be notched so that the bottom part 11 and the container main body P may be connected in a flush manner.

  Further, the bottom portion 11 may have a protruding portion 11 a that protrudes along the inner peripheral edge of the peripheral wall portion 12.

  Next, the structure of each part constituting the packaging container will be described in detail with reference to FIGS.

As shown in FIGS. 1 and 2, the packaging container is a packaging container made of a thermoplastic resin molded in a substantially rectangular shape in plan view, and a container body P that stores food (for example, soba) and In order to hold a small container for storing another food (for example, soba soup), a small container holding part 1 formed integrally with the container body and for storing another food (for example, soba seasoning) Therefore, the container main body and the small container holding part may be provided with a storage part T that is integrally molded. For the consumer located in front of the packaging container, the container body 1 may be arranged on the right side, the small container holding part 1 on the left front side, and the small placement part T on the left back side.
In addition, you may design the arrangement | positioning and volume ratio of the container main body 1, the small container holding part 1, and the small mounting part T according to the kind of foodstuff.

The container main body P has a substantially square main body bottom part P1 in a plan view on which food is placed, a main body side wall part P2 rising obliquely outward from the periphery of the main body bottom part, and an upper end of the main body side wall part. A main body flange portion P3 extending outward may be provided. For consumers located in front of the packaging container, the container main body P includes a small container holding portion 1 at a position corresponding to the corner portion on the left front side in addition to both the corner portions on the back side and the corner portion on the right front side. May be arranged.
The shape of the main body bottom P1 may be circular or elliptical, and is not limited. A plurality of rectangular ribs that increase rigidity may be provided on the main body side wall P2.

The main body bottom portion P1 may include a raised portion P1a that bulges at a predetermined height in the center portion, and rib portions (not numbered) that are formed radially including the raised portion. The raised portion P1a may have an elliptical shape lacking a portion near the small container holding portion 1 or may have a sharp apex. In the rib portion, linear long ribs and short ribs may be alternately arranged. There may be a circular region in which the rib portion is not arranged in the central portion of the raised portion P1a. According to such a structure, the volume feeling of the food provided by the raised portion P1a can be improved, and the rib portion can more easily loosen the food when stirring.
In addition, there is no limitation in the dimension and shape of the protruding part P1a with respect to the main-body bottom part P1, and a rib part, and any may be sufficient as long as there is no problem in the appearance of food and the ease of eating.

The small container holding part 1 includes at least a bottom 11 having a substantially circular shape in a plan view on which the small container is placed, and a peripheral wall 12 that rises outward from the periphery of the bottom, and is provided on the peripheral wall. May be formed with a notch 13 cut out so as to communicate with the container body 1.
In addition, there is no limitation in the shape with respect to the shape of the bottom part 11, the surrounding wall part 12, and the notch part 13, and the container main body 1. FIG.

The bottom part 11 may have a belt-like protrusion part 11 a having a predetermined height and width protruding along the peripheral wall part 12. The height of the protrusion 11a with respect to the bottom 11 may be 0.5 mm to 5 mm. According to such a structure, when the small container is placed on the protruding portion 11a, a gap may be generated between the bottom portion 11 and the bottom portion of the small container. The bottom portion 11 may be provided with a single or a plurality of circular rib portions (not numbered).
In addition, the height of the protrusion part 11a with respect to the bottom part 11 may be equivalent to the outer diameter of the food to be placed on the container body 1, for example. The protrusion 11a is not limited to a belt shape, and may protrude intermittently or partially.

The peripheral wall portion 12 may have peripheral wall front end portions 12a and 12a protruding from the boundary portion between the container main body P and the small container holding portion 1 toward the inside of the container main body. The inner peripheral edge of the peripheral wall portion 12 may be formed in a smooth arc shape including the peripheral wall tip portions 12a, 12a. According to such a structure, desired rigidity is ensured and the container main body P and the small container holding part 1 can be molded integrally, and the peripheral wall tip portions 12a and 12a prevent the small container from being displaced. be able to.
The peripheral wall front end portions 12 a and 12 a have a front end portion (not numbered) corresponding to the boundary between the peripheral wall portion 12 and the cutout portion 13, and the front end portion may be an inclined surface steeply inclined with respect to the bottom portion 11. That is, the interval between the upper ends may be longer than the interval between the lower ends at the distal end portions of the peripheral wall front end portions 12a and 12a. Each of the front-end | tip parts of the surrounding wall front-end | tip parts 12a and 12a may face the inner side of the container main body. According to such a structure, the front end portions of the peripheral wall front end portions 12a and 12a are unlikely to become an obstacle when the small container is put in and out, and the position shift of the small container can be prevented. Moreover, the small container holding | maintenance part 1 becomes open | released and it can also feel the capacity | capacitance of the container main body P more than actually.
The peripheral wall portion 12 may be provided with a plurality of rod-like ribs that increase rigidity from the upper end to the lower end. The shapes of the tip portions of the peripheral wall tip portions 12a, 12a may be planar or bulged, and may be substantially triangular or trapezoidal when viewed from the front. The distance between the lower ends and the distance between the upper ends of the distal end portions of the peripheral wall front end portions 12a and 12a may be equal or the distance between the lower ends may be longer. Each of the front end portions of the peripheral wall front end portions 12a and 12a may face the inside of the small container holding portion 1 or may face the opposite direction. The end face shape of the peripheral wall tip portions 12a, 12a cut in parallel with the bottom portion 11 may be substantially triangular or trapezoidal.

The notch 13 may correspond between the peripheral wall tip portions 12 a of the peripheral wall portion 12. The width of the notch 13 may be 1/5 to 1/4 of the circumferential direction of the peripheral wall 12. The position of the notch 13 may be a location corresponding to the boundary between the adjacent container body P and the small container holding part 1. The depth of the cutout portion 13 may be cut out so that the bottom portion 11 and the main body bottom portion P1 are connected in a flush manner. According to such a structure, the cutout portion 13 facilitates the insertion / extraction of the small container with respect to the small container holding portion 1 and the food is placed because there is no barrier separating the small container holding portion from the container main body P. A wide area can be secured.
The depth of the cutout 13 may be cut out so that a step with a predetermined height is generated between the bottom 11 and the main body bottom P1. At the boundary between the bottom 11 corresponding to the notch 13 and the main body bottom P1, there are convex ribs by embossing or the like that serve as a standard for placing food on the bottom of the main body, and the moisture and soup of the food placed on the bottom of the main body. Alternatively, a drip stop that is recessed so that oil does not flow to the bottom 11 may be provided.

  Next, the usage situation of this packaging container is demonstrated, referring FIGS. 8-10.

First, as shown in FIG. 8, when using the packaging container, the small container S may be placed on the small container holding unit 1, and the lid C may be mounted thereon.
The small container S is a substantially cylindrical container having a slightly larger opening edge than the inner diameter of the bottom portion, and the bottom portion may have a circular rib protruding inward from the center portion. The lid C may be of an external fitting type with respect to the container main body P, and may have a structure in which the top surface portion abuts against the opening edge of the small container S when the lid is closed to prevent displacement.

  Next, as shown in FIGS. 9 and 10, when the small container S is in the small container holding part 1, the peripheral wall part 12 of the small container holding part 1 is 4/5 to 3/4 of the circumferential direction of the small container S. And the peripheral wall tip 12a, 12a is prevented from slipping out of the notch 13 that is notched in the circumferential direction 1/5 to 1/4 of the portion adjacent to the container body P. May be. Since the small container S is placed on the protruding portion 11a of the bottom portion 11 of the small container holding portion 1, a gap may be generated between the bottom portion of the small container holding portion and the bottom portion S1 of the small container. Since the notch 13 of the small container holding part is cut out so that the bottom part 11 of the small container holding part 1 and the main body bottom part P1 of the container main body P are flush with each other, the boundary between the bottom part and the bottom part of the main body A gap may also be formed between the position corresponding to the bottom S1 of the small container S.

  As described above, the packaging container according to the present embodiment has a circumferential wall portion 12 of the small container holding portion 1 formed integrally with the container main body P at a position adjacent to the container main body in the circumferential direction from 1/5 to 4 minutes. By forming the cutout portion 13 that is cut out by one, it is possible to expect the effect of placing the small container S so that the small container S is easily fitted and is not easily displaced. Furthermore, when the small container holding | maintenance part 1 is provided inside the container main body P, the effect which ensures the storage area | region of the foodstuff with respect to this container main body by the notch part 13 can be anticipated. That is, since a part of the peripheral wall portion 12 that separates the container main body P and the small container holding portion 1 is replaced by the notch portion 13, the storage area of the food placed in the container main body is expanded to the small container holding portion 1. Can do.

  Further, when the small container S is removed, the notch 13 is cut out so that the bottom 11 of the small container holder 1 and the main body bottom P1 of the container main body P are flush with each other. The effect that the food inside can be spread and mixed to the bottom of the small container holding portion can be expected. That is, when noodles such as buckwheat are hardened before eating, not only the chopsticks are rotated with respect to the noodles but also swayed in all directions so that the noodles are easily diffused and easily loosened.

  Moreover, the bottom part 11 of the small container holding part 1 has the protrusion part 11a which protrudes along the inner periphery of the surrounding wall part 12, By this, the bottom part S1 of the small container S and the bottom part of this small container holding part at the time of mounting Since a gap can be formed between the two, the effect of not being crushed can be expected even if the served food or the like spreads to the bottom of the small container holding portion. For example, when noodles are arranged in line production, several noodles provided from the apparatus enter the bottom part 11 of the small container holding part 1 beyond the bottom part P1 of the container body P, which is the original serving place. Even when the small container S is placed, the food in the bottom portion of the small container holding part fits in the gap described above and does not collapse and does not lose its shape, thereby contributing to maintaining the appearance and the hygienic quality of the food. be able to.

  The packaging container, the lid C, and the small container S in this embodiment are formed by thermoforming a synthetic resin sheet by sheet forming such as vacuum forming, pressure forming, vacuum pressure forming, double-sided vacuum forming, hot plate forming, etc. It may be formed by doing. As the synthetic resin sheet, for example, a polyester resin such as polyethylene terephthalate, a styrene resin such as polystyrene, or an olefin resin such as polypropylene may be used. As the resin, for example, if a foamed resin is used, it is preferable because it is lightweight and has heat insulating properties. Furthermore, the front surface or the back surface of the sheet may be covered with a synthetic resin film, and when the surface is covered, printing may be performed. The thickness of the synthetic resin sheet is not particularly limited, but may be 0.15 to 0.5 mm, preferably 0.18 to 0.45 mm, and more preferably 0.2 to 0.35 mm.

  The packaging container according to the present invention can be used not only in industries related to the manufacture, wholesale, and retail of packaging containers and foods, but also in the food service industry, the medical industry, and other industries that handle containers.
