Description

The present invention relates to a container inner plate structure, and more particularly to a container inner plate structure provided with an ingredient mounting inner plate attached to an opening of the container body.

In recent years, the types of foods and drinks sold at convenience stores and the like are extremely diverse, and in addition to prepared foods, bento boxes, sandwiches, etc., they are expanding to salads, desserts, noodles, and other processed foods. When selling such foods, a container in which a lid is superposed on a container body made of a synthetic resin sheet is often used.

Of the foods listed, lunch boxes are generally packaged and sold with all the ingredients in one container. This is due to the processing and cooking methods that make the assorted ingredients familiar with each other and present a delicious taste as a whole. This is also because the water content of the foodstuffs used is relatively uniform. On the other hand, in the case of noodles such as buckwheat noodles, udon noodles, and pasta, the noodles and the ingredients to be placed on the noodles may be combined at the time of manufacture. However, there may be a difference between the water content of the noodles and the ingredients placed on them. For this reason, it tends to become soggy at the time of eating and the taste tends to deteriorate. In recent years, the demand for taste has been increasing, and it is a problem that cannot be ignored for each retail store and seller in order to differentiate from other companies and obtain customer satisfaction.

Therefore, as a relatively simple measure, there is a container using an inner plate (inner lid) in the container composed of the container body and the lid (see, for example, Patent Document 1). According to this container, for example, noodles are stored in the lowermost part of the container body, an inner plate is placed in the opening of the container body, appropriate ingredients are placed on the inner plate, and finally a lid is covered. In the case of this container, it is possible to suppress the mixing of the ingredients before eating and bring the taste closer to the freshly made taste. In addition, since the topping ingredients are lined up on the middle plate, the appearance is gorgeous.

In the conventional container, when transferring the ingredients on the inner plate to the container body side, the ingredients are picked up with chopsticks etc. and transferred one by one, or the inner plate is tilted above the opening of the container body and the ingredients are transferred into the container body. It is common to follow the procedure such as dropping the. However, it is troublesome for the user to transfer the ingredients one by one. In addition, tilting the inner plate to drop the ingredients makes it easy to spill the ingredients, so you need to be careful not to spill them, or spilling them will stain the surroundings. Therefore, in the conventional container, the operation and procedure of transferring the ingredients on the inner plate are troublesome, and improvement in handling difficulty has been required.

At the time of eating, the user releases (opens) the fitting between the container body 11 and the lid 20, and the middle plate 30 on the step 16 of the container body 11 is lifted in a substantially horizontal state. At that time, the lifted middle plate 30 is maintained in a substantially horizontal state so that the ingredient F2 does not spill, and is arranged above the opening 15.

When lifting the middle plate 30, as shown in FIGS. 8 (a), 9 (a), and 10 (a), the left finger knob portion 40 and the right finger knob portion 50 are lifted by the finger of the user M. It is supported by being pinched. That is, the first movable wall portion 41 and the second movable wall portion 42 facing each other in the left finger knob portion 40 are sandwiched by the fingers of the left hand of the user M, and the third movable wall portion 51 and the opposite third movable wall portion 51 and the right finger knob portion 50 face each other. The fourth movable wall portion 52 is sandwiched between the fingers of the user M's right hand. When the left and right finger knobs 40 and 50 are pinched with fingers, the left and right finger knobs 40 are formed by forming recesses 49, 49, 59 and 59 at the lower parts of the movable wall portions 41, 42, 51 and 52, respectively. The range to which the finger can be attached is widened for, 50, and the user M can easily pinch.

Subsequently, as shown in FIGS. 8 (b), 9 (b), and 10 (b), the movable wall portions 41, 42, 51, and 52 of the left and right finger knob portions 40 and 50 are operated by the user M to pinch. The dish surface portion 32 of the dish body portion 31 is curved by being pressed inward. Here, in the left finger knob portion 40, the first movable wall portion 41 and the second movable wall portion 42 facing each other are connected via the left arcuate wall portion 43 on one side, and the left standing wall portion 45 is connected on the other side. A gap S is interposed between the first movable wall portion 41 and the second movable wall portion 42. Therefore, the gap S is crushed by the pressure from the user M, and the first movable wall portion 41 and the second movable wall portion 42 are moved so as to be close to each other.

At this time, since both ends of the first movable wall portion 41 and the second movable wall portion 42 are connected to the left arc-shaped wall portion 43 or the left standing wall portion 45, respectively, the first movable wall portion 41 and the second movable wall portion 41 and the second movable wall portion 45 are connected. The left arcuate wall portion 43 and the left standing wall portion 45 are deformed so as to bend outward as the portion 42 approaches by pressing. Since the left arcuate wall portion 43 and the left standing wall portion 45 are deformed to the outside, the first movable wall portion 41 and the second movable wall portion 42 are smoothly brought close to each other. In particular, the left deformation assisting portion 46 formed on the left standing wall portion 45 acts so as to accurately deform the left standing wall portion 45 to the outside (see FIG. 8B). Specifically, since the left deformation assisting portion 46 is a mountain-folded bulging portion 46A, the left standing wall portion 45 is surely bent (bent) outward and deformed. The same operation is performed when the left deformation assisting portion 46 is a vertical slit portion 46B.

Further, since the left standing wall portion 45 is connected to the left dish portion 31A, the left dish surface portion 32a of the left dish portion 31A is curved so as to bend downward due to the above deformation. In particular, in the left standing wall portion 45, since the left reinforcing wall portion 48 is formed at the connecting portion with the left dish portion 31A, the side of the connecting portion with the left dish portion 31A is pulled up via the left reinforcing wall portion 48. Transform as follows. As a result, the deformation of the left standing wall portion 45 is effectively transmitted over a wide range of the left dish portion 31A (left dish surface portion 32a), and the bending deformation of the left dish portion 31A is appropriately and smoothly performed. Further, by forming the left deformation assisting portion 46 (bulging portion 46A) into a triangular pyramid shape, the shape of the bottom side of the left standing wall portion 45 is maintained, and the left dish portion 31A can be curved more greatly. Then, when the left dish portion 31A (left dish surface portion 32a) is curved and deformed, the groove portion 36 that is convex downward is formed on the left dish surface portion 32a, so that the groove portion 36 starts to be curved downward. .. That is, it is curved so that the substantially central portion of the left dish portion 31A is the lowest point.

When the left reinforcing wall portion 48 is provided with the left protruding portion 48C as in the left finger knob portion 40 of the second embodiment shown in FIGS. 12 and 13, a part of the left connecting lateral wall portion 48B is the outer edge portion 34. By being bent to the side, the left vertical wall portion 45 can be easily deformed in a mountain-folded shape by the left deformation assisting portion 46. Then, the deformation tends to be concentrated on the left dish portion 31A (left dish surface portion 32a) around the left standing wall portion 45, and more accurate bending deformation of the left dish portion 31A becomes possible.

On the other hand, also in the right finger knob portion 50 formed symmetrically with the left finger knob portion 40, the right plate portion 31B is curved in the same manner as the left plate portion 31A by the pinching operation of the user M. That is, the third movable wall portion 51 and the fourth movable wall portion 52 are brought close to each other by the pressure from the user M, and the right arc-shaped wall portion 53 and the right standing wall portion 55 are deformed so as to bend outward accordingly. Then, as the right standing wall portion 55 is deformed, the side of the connecting portion with the right dish portion 31B is pulled up via the right reinforcing wall portion 58 so that the substantially central portion becomes the lowest point with the groove portion 36 as the base point. The right dish portion 31B is curved. Further, as the second embodiment, even when the right reinforcing wall portion 58 is provided with the right protruding portion 58C, the right dish portion 31B can be accurately curved and deformed by the same action as described above for the left protruding portion 48C. It becomes.

In this way, the dish surface portions 32a and 32b of the left and right dish portions 31A and 31B, that is, the dish surface portion 32 of the dish body portion 31, points to the groove portion 36 by the knob operation on both the left and right finger knob portions 40 and 50 by the user M. It is curved downward with the central part as the lowest point. Due to the curvature of the dish surface portion 32, the ingredient F2 placed on the dish body portion 31 (31A, 31B) has the lowest point of curvature (groove portions 36, 36) along the downward inclination of the left and right dish portions 31A, 31B. Guided in the side) direction.

Then, as shown in FIG. 5, the cut opening 60 is opened by the user M pulling the left and right finger knobs 40 and 50 away from each other while maintaining the curved state of the dish surface portion 32. It is opened. That is, the dish body portion 31 is separated from the left dish portion 31A and the right dish portion 31B with the notch opening 60 as a boundary. In particular, since the left and right dish surface portions 32a and 32b are curved downward at the substantially central portion, the left and right dish surface portions 32a and 32b are abbreviated as the dish body portion 31 (dish surface portion 32) due to the separation of the left and right dish portions 31A and 31B. It becomes an inclined state that descends toward the central part. As a result, the opening of the cut opening 60 is greatly widened at the substantially central portion of the countersunk surface portion 32.

Therefore, in the ingredient F2 guided toward the lowest point (groove 36, 36 side) of the curvature of the dish surface portion 32, the inclination of the left and right dish surface portions 32a and 32b is accompanied by the opening of the cut opening 60, and the dish body portion By changing in the substantially central direction of 31 (dish surface portion 32), the plate is further guided and dropped in the direction of the opened cut opening 60. At that time, the countersunk reinforcing portion 35 also acts as a guide portion in the notch opening 60 direction because it extends substantially parallel to the groove portion 36. Therefore, the ingredient F2 is more reliably guided in the direction of the cut opening 60. In this way, by bending the dish surface portion 32 in advance at the time of opening the notch opening 60, it is appropriate in the direction of the notch opening 60 in which the ingredient F2 on the dish body 31 (31A, 31B) is opened. The ingredient F2 can be reliably transferred to the container body 11 side without spilling.

As illustrated and explained above, in the middle plate structure of the present invention, the notch opening can be opened by simply performing a simple procedure of pulling the left and right finger knobs in a direction away from each other in addition to the operation of knobs of the left and right finger knobs. It is possible to open the opening and drop the ingredients on the inner plate into the container body 11 to transfer them. In particular, when the cut opening is opened, the plate surface in the vicinity thereof is curved downward, so that the ingredients on the middle plate can be appropriately guided to the cut opening, and the ingredients on the middle plate can be guided to the cut opening. It can be reliably transferred to the container body side without spilling. Therefore, unlike a conventional container provided with a middle plate, a complicated procedure such as transferring the ingredients on the middle plate one by one with chopsticks or the like becomes unnecessary, and the troublesomeness immediately before eating is eliminated. In addition, since the notch opening is opened by the operation via the left and right finger knobs and the ingredients on the inner plate fall, the simple operation of the user can be changed to complicated deformation of the inner plate and the ingredients can be dropped. The fun of the process is created.

The material, size, shape, etc. of the container having the middle plate structure of the present invention are optimally selected in consideration of the purpose of use of the container and the type of the contained article. Therefore, the present invention is not limited to the configurations and articles of the embodiments illustrated and detailed. For example, the noodles and rice bowls disclosed in the embodiment and the toppings thereof are not limited to those, and toppings of side dishes such as crackers, omelets, and mapo tofu for lunch boxes, fried rice, nasi goreng, pilaf, open sandwiches, salads, and the like. Can also be assumed. For sweets such as ice cream, pancakes, cakes, parfaits and sundaes, anmitsu, zenzai, almond tofu, etc., it can be applied to various food packaging such as toppings such as chestnuts, almonds, chocolate, red bean paste and bean paste. It is possible.

Further, when the opening of the container body is substantially circular, the planar shape of the inner plate is also circular. At that time, the straight line connecting the left and right finger knobs is arranged so as to pass through the center of the middle plate (the center of the circular shape), and the notch opening extends between the left and right finger knobs and the opposite outer edges different from the left and right finger knobs. It is placed at the position where it intersects the straight line connecting the knobs.

As described above, the middle plate structure of the present invention does not require a complicated procedure for transferring the ingredients on the middle plate, and can be reliably transferred without spilling. Therefore, it is most suitable for use as a middle plate of a container for processed foods in which a plurality of foodstuffs such as main foodstuffs and ingredients are separately stored.
