Means for Solving the Problems and Functions / Effects In order to solve the above technical problems, the container cover according to the present invention is configured as follows. That is, this container cover is a container cover for covering a cylindrical container body, and is composed of two square or rectangular, substantially resilient, substantially identical shaped side plates arranged in an overlapping manner, and the two side plates. A connecting portion that connects to bendably deform and deform into a cylindrical shape, and a locking portion formed on at least one of the upper and lower ends of the inner surface of each side plate. The locking portion separates the container cover from the central portion of the side plate. As described above, by bending and deforming into a cylindrical shape, the side plate is configured to protrude from the inner surface.

The container cover is configured to insert and hold a cylindrical container body in a space between the side plates in a state where the opposing side plates are opened outward in a direction in which the side plates are separated from each other and are cylindrical. The locking portion of the cover is configured to be in contact with the end of the cylindrical container body from outside.

In the above configuration, since the container cover can be deformed into a cylindrical shape, the cylindrical container body can be easily inserted therein. Also, when the container body is inserted into the container cover, the locking portion protrudes from the inner surface of the side plate, so that the end of the container body is caught by the locking portion, and the container body comes out from at least the side where the locking portion is provided. Can be prevented. Thus, according to the above configuration, the packaging operation can be made simple and reliable. In addition, for example, containers such as jellies are often cup-shaped containers as described above, and thus, the use of a cylindrical container in this manner has an effect that the design is unusual, so that it becomes more noticeable among displayed products. There is also.

In the above structure, the locking portion is connected to the side plate at an end edge of the side plate or a bottom side substantially parallel to the side plate so as to bendable and narrower than the side plate. The locking piece can be configured to be able to bend along a line passing through the intersection of the bottom side and the side side, and is configured of a sticking piece that is connected to the side so as to bendable and that is bonded to the inner surface of the side plate.

With this configuration, the locking piece is folded along the side plate when the side plates of the container cover are overlapped, but the container cover is closed so that the central portions of the side plates are separated from each other. When it is bent and deformed into a shape, the locking piece that is folded back on the inner surface of the side plate, the outer sticking piece is attached to the inner surface of the side plate, so the curved length of the side plate is longer than the length of the locking piece. The locking piece is bent inward by the action of maintaining the dimensional difference between the inner and outer diameters, and the locking piece projects from the inner surface of the side plate. Therefore, when the container main body is inserted into the container cover, the container main body can be reliably held.

In the above configuration, it is preferable that the locking portions are formed at both upper and lower ends of the side plate. The locking portion can prevent the container body from falling down when holding the container cover if it is formed at least at the lower end,
If the container is provided at both upper and lower ends in this manner, the container body can be prevented from falling off even when the container is turned upside down, so that it does not drop out or be removed during transportation or sale.

The container cover may not only be formed of two side plates, but also may be configured so that a greater number of left and right side plates can be folded at the connecting portion. Even in that case, by forming a tubular shape so that the side plates facing each other open outward in a direction away from the folded state of the side plates, a locking portion protruding from at least one of the upper and lower ends of the inner surface of the side plate is provided. It is good.

Further, in the above construction, the cylindrical container body is provided with a locking flange projecting laterally from the peripheral surface along the axis, and the locking flange is attached to the container cover with respect to the container cover. It can be configured so as to be substantially in contact with the connecting portion when inserted, so that the locking flange can be prevented from rotating with respect to the container cover.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to FIGS.

First, the container cover will be described with reference to FIGS.
This will be described with reference to FIG. FIG. 1 is a development view of the container cover. The container cover 1 is configured to be assembled by folding a paper blank. Reference numerals 11a and 11b denote two side plates having substantially the same rectangular shape, which are foldably connected via a fold line a as a connection portion. 1
Reference numeral 2 denotes an adhering portion which is connected to the left side plate 11a on the left side of the figure so as to be bendable with a folding rule b, and is adhered to the right end of the side plate 11b.

At the upper and lower ends of both side plates 11a and 11b,
The side plates 11a, 11b are formed via the creases c, which are perpendicular to the creases a, b.
The locking piece 13 located substantially at the center of 11b and the sticking pieces 14 located on both sides thereof are connected. The locking piece 13 and the sticking piece 14 are connected to be able to bend at a crease d perpendicular to the crease c. In addition, the locking piece 13 is a crease e passing through the intersection of the crease c serving as the bottom side and the crease d serving as the side.
And can be bent. In addition, each locking piece 13
May be formed at an arbitrary angle if they do not cross each other. Reference numeral 15 denotes two cutting rules, between which the opening piece 16 is formed.

The assembly of the container cover 1 is performed by
And the bonding piece 14 is bent to the inner side of the side plates 11a and 11b with the creases c, and the bonding pieces 14 are bonded to the side plates 11a and 11b, and then the blank is bent by the creases a and b to form the bonding portion 12 Is bonded to the outer surface of the side plate 11b. At this time, since each locking piece 13 is in a state along the inner surfaces of the side plates 11a and 11b, the container cover 1
It becomes a flat rectangular sheet having a size of 1a, 11b.

On the other hand, since the locking piece 13 can be bent with the creases c and d with respect to the side plate and the locking piece 13 itself can be bent with the crease e, the container cover as shown in FIG. 1 is deformed into a tubular shape so that the central portions of the side plates 11a and 11b are separated from each other, and the side plates 11a and 11b are deformed.
Are bent as a whole, whereas the locking pieces 13
It will bend at e. Therefore, the locking piece 13
It protrudes from the inner surfaces of the side plates 11a and 11b (see FIG. 3 (cross-sectional view of the locking portion)).

Next, the container body will be described with reference to FIG. The container body 2 is formed by vacuum-forming a three-layered sheet material in which an ethylene vinyl alcohol film as a gas barrier layer is sandwiched by polypropylene films from the front and back, and has a storage recess 21 having a semicircular cross section in two rows. doing. A flange (locking flange) 22 is provided around the two storage recesses 21, and the two storage recesses 2 are provided.
1 is provided with a hinge 23 for folding the container main body 2 in two to form a column. The hinge portion 23 has elasticity so that when the container body 2 is bent into two, a force is generated so that the superposed surfaces are separated from each other.

In this container body 2, for example, jelly or the like is stored in the storage recess 21, and then a cover film 24 is fused to the flange 22. For example, the cover film 24 is not bonded to the flange 22 at only one corner portion, and is configured as a peeling start position for opening.

In the above construction, first, the container body 2 is folded in two by the hinge portion 23 to form a column, and the container cover 1 swelled in a cylindrical shape is provided with the storage recesses 21 in the creases a and b of the container cover 1. By simply inserting the container body 2 while adjusting the positions of the left and right locking flanges 2, the packaging operation is easily completed. At this time, since the locking pieces 13 project from the side plates 11a and 11b as described above, the ends of the container body 2 are locked to the locking pieces 13. In addition, since an expanding force is generated at the hinge portion 23, the outer peripheral surface of the container main body 2 is pressed against the inner peripheral surface of the container cover 1. Therefore, it is possible to prevent the container body 2 from falling out of the container cover 1. In addition, if the opening piece 16 is cut off from the cutting rule 15, the container body 2 can be easily taken out from the container cover 1.

On the other hand, a product name, a picture, and the like are printed on the container cover 1 and are arranged vertically at the sales floor. If this container is used as a container for jelly, the design is unusual, so that the displayed products are rare. It also has the effect of making it more noticeable in the room. Further, since the container body has two storage recesses 21, two types of jelly having different tastes can be packaged.

It should be noted that the present invention is not limited to the above embodiment, but can be implemented in other various modes. For example, in the above embodiment, the locking pieces 13 are provided at the upper and lower ends of the side plates 11a and 11b. However, the locking pieces 13 may be provided only on one side, and the opposite side may be covered with a film or the like. In addition, although the locking piece 13 is rectangular in the above configuration, it may be trapezoidal in width extending from the crease c to the opposite side, and in this case, the two creases e are mutually connected. If they do not intersect, they may be formed at any angle. Further, the locking pieces 13 are not necessarily provided on the side plates 11a, 11b.
Need not be provided at the center of the camera.

Further, the container body may be formed in a shape other than a columnar shape such as a triangular prism or a quadrangular prism, and the container cover may be constituted by three or more side plates so as to have a corresponding shape. When the container body is deformed in this way, the storage recess is
It can be one, three or more. Even in the case of such a change, the same effect as in the above embodiment can be obtained by providing a locking portion projecting from at least one of the upper and lower ends of the inner surface of the side plate by making the container cover cylindrical from the folded state. Is obtained.

In the above configuration, the opening piece 16 is formed in the left-right direction of the container cover 1, but may be formed in the vertical direction of the container cover 1.
