Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging container, and more particularly to a packaging container used as an outer wrap for protecting stored items.

[0002]

[Prior art]

 For example, in a packaging container for storing stored items such as sashimi, it is necessary to wrap a so-called wrap, which is a transparent film, in order to keep the stored items fresh and to be easily seen from the outside. If the wrap remains in direct contact with the contents for a long period of time, the contents are likely to change. Therefore, in order to prevent the wrap from coming into direct contact with the contents, for example, the actual fair 1-23984. The "spacers for food packaging packs" as proposed in the publication are used.

Since the spacer is, in short, a separate body from the packaging container, the spacer must be positioned and held on the packaging container to perform the above-mentioned wrapping, which deteriorates the wrapping workability. It was a thing. For this reason, for example, as shown in FIG. 5, at least one ejection portion projecting upward may be integrally formed on one side wall portion of the container, and the ejection portion may be the spacer described above. Has been proposed. (Japanese Utility Model Publication No. 4-97015)

According to the conventional packaging container shown in FIG. 5, the inconvenience of using a spacer separate from the container is eliminated, and the reduction of the packaged item (the stored item) by the wrap is prevented. Although it is possible to do so, it is still advantageous, but it still has the following problems. That is, in the packaging container shown in FIG. 5, since the ejection portion is formed as an inward protruding portion, that is, an inward protruding portion is formed, the inward protruding portion There will be spaces on both sides of the ejection part, and the bottom of this packaging container has a so-called irregular shape.

When the bottom surface has an irregular shape, for example, when sashimi is considered as a storage item, not only can the sashimi be arranged neatly, but only the “tsuma” are exposed on the space, which is very unsightly. Becomes In addition, a pattern suitable for the stored items may be formed on the inner surface of this type of container, but in such a case, the pattern is greatly distorted due to the presence of the inward projection and the space. This means that the bottom surface will not be balanced.

On the other hand, the work of wrapping a wrap on a packaging container of this type has been performed mechanically. When the wrapping is performed mechanically, not only when positioning the container itself, but also when the wrap is applied with a certain amount of tension, an unexpected force may be applied to the packaging container. Since the container itself is generally formed from a synthetic resin sheet as a material, it does not have sufficient rigidity, and if an unexpected force is mechanically applied to such a container. It is easy to cause damage to the container. For this reason, the packaging container must be made more rigid by some means.

Therefore, in the present invention, for the packaging container having the protrusion for lifting and supporting the wrap, various examinations have been made on how to solve the above-mentioned problem of the bottom surface deformation and to secure the rigidity. As a result of repeated efforts, 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 a problem to be solved is to simplify the bottom shape of a packaging container having a supporting protrusion for wrapping and to ensure rigidity.

The object of the present invention is to provide a support projection for wrapping, which can sufficiently widen the bottom surface and is necessary for mechanically performing wrapping. The purpose is to provide a packaging container that can ensure sufficient rigidity with a simple structure.

[0010]

[Means for Solving the Problems]

 In order to solve the above problems, the means adopted by the present invention will be described with reference to the reference numerals used in the embodiments. A packaging container 10 having a sloping side wall, in which a part of the side wall is bulged upward within a range of the sloping width L to form a support protrusion 13 protruding from the upper side of the side wall 12, The packaging container 10 ″ is characterized in that the support protrusion 13 does not project on the bottom surface 11.

That is, in the packaging container 10 according to the present invention, the support projection 13 for holding the wrap in a predetermined position needs to be formed by bulging a part of the side wall 12 within the inclination width L thereof. Of. The reason is that by defining the formation position or shape of the support protrusions 13 in this way, the shape of the bottom surface 11 must be simplified and the stored items can be stored neatly, as shown in FIG. Is. That is, by making the shape of the bottom surface 11 substantially similar to the outer shape of the packaging container 10, the formation of the space portion as in the conventional example shown in FIG. Moreover, the bottom surface 11 does not have an irregular shape. In addition, in this packaging container 10, it is necessary that the bottom surface 11 has a curved or bent shape, because the packaging container 10 is sufficiently resistant to the force applied from the wrap. This is because it is necessary that the material has sufficient rigidity.

It should be noted that the above is not limited to the case of the packaging container 10 shown in the embodiment in which the outer shape is a substantially square shape, but can be applied to a round or elliptical shape or other outer shape. is there.

[0013]

In the packaging container 10 according to the present invention configured as described above, as shown in FIGS. 1 and 3, since the supporting projection 13 thereof projects from the upper side of the side wall 12, the packaging container 10 concerned. When sashimi or the like is stored in 10 and wrapped, the wrap is held in a predetermined position by the support protrusions 13 and the wrap does not directly contact the stored items in the packaging container 10.

Further, since the support protrusion 13 is formed so as to project within the inclination width L of the side wall 12, as shown clearly in FIG. In the example, it does not affect the outer shape of the packaging container 10 (a substantially rectangular shape). In other words, the bottom surface 11 of the packaging container 10 does not have a deformed shape, but has a sufficiently large area, which enables a good arrangement of the stored items. Moreover, even if a pattern suitable for a stored item is formed on the inner surface of the packaging container 10, there is no inward protruding portion and space portion unlike the conventional container. In the container 10 for use, the design is not greatly distorted, and the balance of the design can be secured especially on the bottom surface.

Further, as shown in FIG. 3, the bottom surface 11 of the packaging container 10 has a curved or bent shape, and therefore has high rigidity. In particular, in the packaging container 10 of the following examples, the bottom surface 11 has a shape bent at the curved or bent central portion 14, and this curved or bent central portion 14 is the supporting protrusion 13. Since it is orthogonal to, the rigidity required when the force from the wrap is transmitted to the bottom surface 11 side through the support projection 13 is sufficient.

[0016]

【Example】

 Next, the packaging container 10 according to the present invention will be described with reference to the embodiments shown in the drawings. As shown in FIGS. The support projection 13 for supporting the wrap is integrally formed on the side wall 12 which is inclined while expanding. The packaging container 10 is integrally formed by molding a sheet-shaped synthetic resin material (in this embodiment, an expanded polystyrene synthetic resin material, so-called PSP is used). .

As shown in FIGS. 3 and 4, the bottom surface 11 of the packaging container 10 has a curved or bent shape in the approximate center thereof. In the present embodiment, the bottom surface 11 is bent at the curved or bent center portion 14, but the curved or bent center portion 14 is provided with respect to the support protrusion 13 as shown in FIG. It is in the orthogonal direction. In other words, the wrap to be hung on the outer side of the packaging container 10 exerts a force to push the support protrusions 13 into the packaging container 10, and the wrapping wraps the wrapping container 10 even after the wrapping. It is possible that a force is constantly applied to push down the support protrusions 13, but the bottom surface 11 is curved or bent so as to sufficiently withstand such a force. Therefore, it is most effective that the curved or bent center portion 14 is orthogonal to the support protrusion 13 and the bottom surface 11 is curved or bent on both sides of the curved or bent center portion 14. It is expensive.

The side wall 12 is required to be inclined with respect to the bottom surface 11 while expanding, and this makes the volume inside the packaging container 10 sufficient, and the support projection 13 is provided on the side wall 12. This is because it needs to be formed within the inclined width L. As shown in FIG. 4, the inclination width L refers to the length of the inclined side wall 12 when viewed in plan, and as shown in FIG. 2, it slightly protrudes from other portions. It also includes the length of the flange.

Then, as shown in FIGS. 1 to 4, a part of the side wall 12 is bulged so that the support protrusion 13 protrudes from the upper side of the side wall 12 within the range of the inclination width L. Is formed. As shown in FIGS. 3 and 4, the support protrusion 13 is formed with a rounded tip so as not to damage the wrapped wrap. As shown in FIG. 2, it is positioned inward within the range of the inclination width L. In other words, by positioning the tip of the support protrusion 13 inward, a space is formed between the wrap and the outer surface of the support protrusion 13 when the wrap is hung so that the wrap does not adhere to the support protrusion 13. The wrapping work is made easy.

[0020]

[Effect of device]

 As described above, according to the present invention, the side wall 12 is integrally formed with the support protrusion 13 that bulges upward within the inclination width L, and the bottom surface 11 is curved or bent. It has a structural feature that allows the bottom surface 11 to be sufficiently wide even if it has the support projection 13 for wrapping, which is necessary for mechanically performing wrapping. The packaging container 10 that can sufficiently secure the rigidity can be provided with a simple configuration.
