Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a packaging container, and more particularly, to a packaging container with a lid, in which a lid is fitted to a container body.

[0002]

[Prior Art]

 For example, when selling a sandwich or bento for take-out, in order to prevent the sandwich, etc. stored in the container body from going out or touching anything else, the container body (general Typically, a packaging container with a lid is used in which a transparent material) is fitted. This packaging container with a lid is generally formed by subjecting a plastic sheet to pressure molding or vacuum molding, and is mass-produced as a hygienic and inexpensive product. It is a thing.

As described above, in the lidded packaging container formed of the plastic sheet, how to maintain the fitted state of the lid body with respect to the container body, and the entire lidded packaging container How to secure the rigidity of the becomes a problem. The rigidity of the entire packaging container with a lid is secured to some extent by forming irregularities such as flanges and ribs on the container body and lid, but the rigidity of the lid for the container body As for maintaining the mating condition, there is not enough.

The simplest method of maintaining the fitted state of the lid with respect to the container body of such a packaging container with a lid is to form a flange portion extending outward on the container body side. , A flange portion that abuts this flange portion is also formed on the lid side so that the fitted state of the lid body with respect to the container body is maintained by a so-called rubber band hung over the entire packaging container with a lid body. That is. However, the work of hanging one rubber band over the entire packaging container with a lid is quite troublesome, and unlike the angular packaging container with a lid as shown in Fig. 1, the round container as shown in Fig. 3 is used. It is almost impossible for mold-type packaging containers.

Therefore, conventionally, for example, as shown in FIG. 7, a fitting portion is formed in a flange portion or the like on the container body or the lid side, and the fitting portion is formed on the lid body or the container body side flange. The fitting state between the container body and the lid is maintained by engaging with the end of the portion or the like. The fitting portion 40 shown in FIG. 7 is formed on the lid side, and is fitted inside the flange portion of the lid body so as to engage with the lower end edge of the flange portion of the container body side from the lower side in the figure. It is designed to swell. When the lid has the fitting portion 40 like this, when a large number of lids are to be stacked when they are collectively packaged after molding, as shown in FIG. A space is formed between them, making it impossible to store a large amount in a storage box, for example. The above can be said similarly for stacking the container bodies when the fitting portion 40 is formed on the container body side.

Further, a method for solving the above-mentioned problem of stacking by shortening the distance between the fitting portion 40 and the flange portion is proposed by a structure shown in FIG. 9, for example. It has been done. However, with such a structure, if the contents of the container body are to be transported by a container or the like, and the adjacent containers for packaging with a lid overlap each other at their flanges, the container body and the lid are closed. The problem arises that the fitting state with the body easily comes off.

Therefore, the inventors of the present invention can reliably maintain the fitted state of the container body and the lid body, and can efficiently perform stacking of the container body or the lid body for packaging after molding. As a result of various studies on how to proceed, the present invention was completed.

[0008]

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances, and the problem to be solved is to ensure that the fitting state between the container body and the lid is maintained and that the stacking is performed efficiently. To achieve.

The object of the present invention is that the fitting state can be maintained sufficiently and reliably, and the container body and the lid body can be efficiently stacked. It is to provide a packaging container with a lid by a simple structure.

[0010]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the means adopted by the present invention will be described with reference to the reference numerals used in the embodiments. "A package including a container body 10 and a lid 20 fitted to the container body 10" A container 100 for use in which a flange portion 11 extending outwardly from the periphery of the container body 10 and a reinforcing portion 12 that integrally hangs downward from an edge of the flange portion 11 are formed. At the same time, the reinforcing portion 12 is formed with a cutout portion 12a which exposes a partial end portion of the flange portion 11 and serves as an engaging portion 11a. On the other hand, a flange extending outwardly around the lid body 20 is formed. A portion 21 and a skirt portion 22 that integrally hangs downward from the edge of the flange portion 21 in a state shorter than the reinforcing portion 12 on the container body 10 side are formed, and the container body 10 of the skirt portion 22 is formed. Corresponding to the side engaging portion 11a Min is a container 100 for with lid body wrapping, wherein "that it has formed a fitting portion 22a into.

[0011]

[Mode of operation and use of device]

 The operation of the lidded packaging container 100 according to the present invention configured as described above will be described below together with the mode of use thereof.

First, in the lidded packaging container 100 according to the present invention, as shown in FIG. 1, since the notch 12a is formed at the corner of the container body 10, the notch 12a is formed. The corner portion of the flange portion 11, that is, the engaging portion 11a is substantially exposed outward. In the embodiments described below, a small portion of the reinforcing portion 12 corresponding to the engaging portion 11a is left so that the reinforcing portions 12 located on both sides of the cutout portion 12a are completely removed. Not to be separated.

On the other hand, in the corner portion of the lid body 20, as shown in FIGS. 1 and 2, the skirt portion 22 hangs integrally from the end image of the flange portion 21 in a state without a cut, A fitting portion 22 a bulges inward from the inner surface of the skirt portion 22 at the upper corner portion of the skirt portion 22. The vertical height of the skirt portion 22 is shorter than that of the reinforcing portion 12 on the container body 10 side.

By pressing the lid body 20 from the opening side of the container body 10 as described above, the fitting of the both is immediately performed. That is, since the engaging portion 11a formed on the flange portion 11 side of the container body 10 is substantially exposed from the cutout portion 12a of the reinforcing portion 12 and protrudes outward, It is easy to engage with the fitting portion 22a on the body 20 side. Further, in the container body 10 of the embodiment shown in FIG. 1, since the notch 12a is formed in the reinforcing portion 12 located at each corner portion thereof, the fitting of the lid 20 to the container body 10 is performed. This is especially easy in the early stages.

When the above fitting is completed, the flange portion 21 on the lid 20 side is in contact with the upper surface of the flange portion 11 on the container body 10 side, and the contact state and each flange portion 11 and the flange The rigidity of the portion 21 itself also ensures the overall rigidity of the fitted packaging container 100 with lid. Further, in the packaging container with lid 100 in this state, since the length of the skirt portion 22 of the lid body 20 is shorter than that of the reinforcing portion 12 of the container body 10, as shown in FIG. Even when one of the lid-equipped packaging containers 100 overlaps the other lid-equipped packaging container 100, no force is applied to the skirt portion 22 side. Therefore, the fitted state in the lidded packaging container 100 is maintained without being adversely affected by other lidded packaging containers 100.

When the fitting state as described above is released, in other words, when trying to open the lid body 20, the user applies a force to the portion of the skirt portion 22 where the fitting portion 22a is formed. The lid 20 can be easily removed by inserting and closing the engagement of the fitting portion 22a with the engagement portion 11a. In this case, since the notch portion 12a is formed in the reinforcing portion 12 on the container body 10 side, the releasing operation can be easily performed by inserting a finger from here and operating it.

When a large number of the lid bodies 20 configured as described above are stacked, as shown in FIG. 6, no extra space is formed between the lid bodies 20. It can be stacked very efficiently. This is because the fitting portion 22a to be fitted to the engaging portion 11a of the container body 10 is formed on the upper portion (upper end) of the skirt portion 22. In addition, the stacking of the lids 20 is prevented. Because there is nothing to do.

In the case where the packaging container with lid 100 has a quadrangular shape as shown in FIG. 1, when a large number of container bodies 10 are stacked for packaging after molding, the container shown in FIG. When the notch 12a is formed in the reinforcing portion 12 at each corner as in the embodiment, the stacking can be easily performed. Generally, when stacking box-like objects, it is the corners that make the work difficult. However, if there is a notch 12a at each corner as in the container body 10 of the present invention, such stacking work can be performed. This is because the difficulty of does not occur.

[0019]

【Example】

 Next, a container 100 with a lid according to the present invention will be described with reference to the embodiment shown in the drawings, and FIGS. 1 and 2 show a substantially rectangular lidded packaging according to a first embodiment of the present invention. Container 100 is shown.

As shown in FIG. 1, this lidded packaging container 100 is composed of a container body 10 and a lid body 20 which are integrally molded using a plastic sheet as a material. The container body 10 is a part for accommodating a sandwich or the like, and has a flange portion 11 extending outwardly around the opening thereof, and a reinforcing portion 12 hanging from the outer end side of the flange portion 11 integrally. It is formed in a special way. In the container body 10 shown in FIG. 1, cutouts 12a are formed by cutting the reinforcing portions 12 located at the respective corners. As a result, the portion of the flange portion 11 located at the corner portion becomes the engaging portion 11a, and the engaging portion 11a is located outside so that the fitting portion 22a on the lid 20 side described later can be easily fitted. It is projected to one side. It should be noted that each notch 12a in the present embodiment is not formed by cutting off all the corresponding portions of the reinforcing portion 12, but is cut out so that the upper end of the reinforcing portion 12 is slightly left. It was formed. This is because the rigidity of the engaging portion 11a becomes small if the engaging portion 11a is made into a perfect plate shape, but the reinforcing portion 12 is left to the extent that the fitting portion 22a described later can be fitted. Thereby, the rigidity of the engaging portion 11a can be secured by the remaining portion. To form such a cutout 12a, for example, the shape of the trimming blade 32 shown in FIG. 4 is changed to the shape of the cutout 12a shown in FIG. 1, that is, partially retracted. This is easy to do.

On the other hand, as shown in FIG. 1, the lid body 20 has a flange portion 21 having a width substantially the same as that of the flange portion 11 on the container body 10 side extending outwardly on the outer periphery of the portion serving as the top plate. The skirt portion 22 is integrally formed on the outer peripheral end of the flange portion 21, and the fitting portion 22a that bulges inward is formed at the upper end of each corner portion of the skirt portion 22. It was done.

In order to form such a fitting portion 22a, for example, a mold 30 as shown in FIG. 4 is used. That is, in the lower mold of the mold 30, a recess 31 as shown in the left part of FIG. 4 is formed, and a part of the plastic sheet softened by heating or the like is in the recess 31. Is set to a negative pressure, that is, vacuum molding is performed to form the fitting portion 22a. Then, after the whole of the mold 30 is trimmed into a predetermined shape, the trimming blade 32 trims the outer shape of the skirt portion 22 to perform cutting, whereby the lid body 20 having the necessary fitting portion 22a is obtained. It is.

The reinforcing portion 12 on the container body 10 side and the skirt portion 22 on the lid body 20 side are formed outwardly in a flared shape, and by doing so, the mold 30 described above is formed. It facilitates the die-cutting from or from these, and also facilitates the stacking of each.

FIG. 3 shows a lidded packaging container 100 according to a second embodiment of the present invention, except that the lidded packaging container 100 has a round planar shape. This is the same as the respective components of the lidded packaging container 100 of the first embodiment. In such a round packaging container 100 with a lid, unlike the rectangular container, there is an advantage that the position of the lid body 20 with respect to the container body 10 can be freely set, but a fitting position. Need to be able to set freely. Therefore, in this embodiment, the fitting portion 22a on the lid 20 side is formed over the entire circumference of the skirt portion 22.

[0025]

[Effect of the device]

 As described above, in the present invention, as illustrated in the above embodiment, for example, the engaging portion 11a is formed by providing the notch 12a in the reinforcing portion 12 on the container body 10 side, and the engaging portion 11a is formed. The feature is that the fitting portion 22a that engages with is formed on the upper portion of the skirt portion 22 on the lid body 20 side, and of course, the fitting state can be maintained sufficiently and reliably. Thus, it is possible to provide a packaging container with a lid, which can efficiently stack the container body and the lid, with a simple configuration.
