Description

Packaging container

The present invention relates to a packaging container and a method for producing the same.

Patent Literature 1 discloses a packaging container manufactured by filling a cup-shaped container body with contents such as food and closing an upper opening of the container body with a cover member.

JP 2014-061932 A

However, in the case where the side wall of the container body is asymmetric and the direction for attaching the cover member is determined, if the cover member is attached in the wrong direction, the cover member will be forcibly attached to the container body. As a result, the container body or the cover member may be damaged or may not be used properly. The present invention has been made in order to solve the above-mentioned problem, and an object of the present invention is to provide a packaging container and a method for manufacturing the same, which can attach a cover member to a container body in a correct direction.

A packaging container according to the present invention includes a cup-shaped container main body for storing contents, and a cover member for closing an upper opening of the container main body, and at least one edge of an edge of the upper opening of the container main body is provided. One notch is formed.

According to this configuration, since the notch is formed in the container body, the orientation of the container body can be visually recognized based on the position of the notch, and can be recognized by touching with a finger without relying on the eyes. it can. Thus, the cover member can be attached to the container body in the correct direction after the container body is installed in the correct direction.

In the packaging container, the container main body may have a pair of side walls facing each other, and the pair of side walls may have an asymmetric shape.

As described above, if the side wall portion of the container body has an asymmetric shape, a failure such as breakage may occur unless the cover member is attached in a correct direction with respect to the container body. It is particularly advantageous to have a notch.

In the packaging container, the side of the container body may be configured to be visible from one side of the container body through the notch in the side view.

According to this configuration, for example, when irradiating the container body with light such as a laser from one side, the laser can pass through the notch to the other side, so that when the laser is received on the other side It can be determined that the container body is installed in the correct orientation. Therefore, it is possible to automatically determine whether the orientation of the container body is correct.

In the packaging container, the container main body can be formed in various shapes. For example, the container main body can be formed in a column shape having an elliptical cross section as a shape that can be easily held by hand.

If the cross-sectional shape of the container body is formed into an elliptical shape, it may be difficult to determine whether or not the container body is correctly oriented when the cover member is attached to the container body in a predetermined direction. Therefore, it is particularly advantageous to form the notch as described above.

In the packaging container, the notch may be formed to include a longitudinal end of the upper opening in a plan view.

If the notch is formed in this way, it is possible to visually recognize the other side through the notch from one side of the container body simply by forming the notch at one position of the edge of the upper opening of the container body Can be configured. Therefore, the notch can be reduced, and a decrease in the strength of the container body can be prevented.

In addition, since the notch is provided at the end portion, the direction of the container main body is easily visually recognized, and the direction of the container main body is easily visually recognized or touched without irradiating light as described above. be able to.

In the packaging container, the cover member may include a peripheral wall portion that covers an upper end portion including an upper opening of the container body, and the cutout may be formed at the upper end portion.

Accordingly, when the cover member is attached, the notch is covered by the peripheral wall portion of the cover member, so that not only the content does not spill out but also the notch can be prevented from being seen from the outside. Thereby, the appearance of the packaging container can be improved.

In the packaging container, the position at which the notch is formed is not particularly limited. For example, an engagement portion is formed at the upper end portion, and the engagement portion is formed at an inner surface of a peripheral wall portion of the cover member. When the engaged portion is formed, the notch can be formed on the upper opening side of the upper end portion with respect to the engaging portion.

With this configuration, since the notch does not interfere with the engaging portion, the engaging portion and the engaged portion can be firmly engaged, and as a result, the cover member can be firmly fixed to the container body. Can be.

In the packaging container, when the container body is viewed from the one side, the container body is configured so that the other side can be viewed from one side of the container body through the cutout in a side view. The area of the notch may be less than 50% of the area above the engagement portion at the upper end.

According to this configuration, by setting the area of the notch to be less than 50% of the area above the engaging portion at the upper end, the position of the notch with respect to the upper end can be easily visually recognized. If the orientation of the main body is wrong, it can be easily recognized. In addition, when the light is irradiated as described above, if the area of the notch is 50% or more, the light may pass through the notch even if the direction of the container body is wrong. Therefore, by setting the area of the notch to be less than 50%, it is possible to accurately confirm the orientation of the container body using light.

In the packaging container, a protrusion inserted into the cutout may be formed on an inner surface of the cover member.

According to this configuration, for example, when the cover member is not mounted in the correct orientation with respect to the container body, the protrusion contacts the edge of the upper opening of the container body, which hinders the Cannot be attached to the main unit. On the other hand, when the cover member is mounted in the correct orientation with respect to the container body, the protrusion is inserted into the notch, so that the protrusion does not interfere with the edge of the upper opening, and the cover member is attached to the container body. be able to. Therefore, by providing the protrusion, it is possible to prevent the cover member from being attached to the container body in an incorrect direction.

A method for manufacturing a packaging container according to the present invention includes the steps of: preparing a container body formed in a cup shape for accommodating contents and having at least one notch formed at an edge of an upper opening; After confirming the orientation of the container body based on the chipping, filling the container body with contents, and attaching a cover member so as to close an upper opening of the container body. .

In the method for manufacturing a packaging container, the side of the container body may be configured to be visible from one side of the container body through the cutout in the side view.

In the method for manufacturing the packaging container, prior to the step of filling the contents, the method further includes a step of irradiating light from the one side toward the notch, wherein the light passes through the notch. When light is received on the other side, it can be determined that the container body is correctly installed.

It is a bottom view. As shown in FIGS. 4 to 8, the container body 1 has an elliptical bottom wall portion 11 and a side wall portion 12 extending upward from the periphery of the bottom wall portion 11, and these are made of a resin material. Are formed integrally. As shown in FIG. 8, the bottom wall portion 11 includes a first side 111 and a second side 112 extending in the longitudinal direction, and a third side 113 and a fourth side 114 extending in the lateral direction, and these are combined. This forms an elliptical outer shape. The first side 111 is located on the front side, and the second side 112 is located on the rear side. The first side 111 and the second side 112 face each other and are formed in an arc shape that is convex outward. On the other hand, the third side 113 is located on the right side, and the fourth side 114 is located on the left side. The third side 113 and the fourth side 114 face each other and are formed in an outwardly convex arc shape.

As shown in FIG. 8, the side wall 12 includes a first surface 121, a second surface 122 extending from the first side 111, the second side 112, the third side 113, and the fourth side 114 of the bottom wall 11, respectively. It has a third surface 123 and a fourth surface 124. However, in the side wall part 12, the connection part 125 with the bottom wall part 11 is formed in an arc-shaped cross section. That is, it is chamfered in an arc shape that is convex outward. Further, a thin portion (upper end portion) 126 having a small thickness is formed over the entire circumference from the upper opening 120 of the side wall portion 12 to a predetermined length downward. The cover member 2 described above is attached to the thin portion 126. In the following, for convenience of description, a portion of the side wall portion 12 below the thin portion 126 may be referred to as a main body portion 127.

As shown in FIG. 5, the first surface 121 and the second surface 122 of the side wall portion 12 have substantially the same thickness, but the inclination angle of the first surface 121 from the bottom wall portion 11 is larger than that of the second surface 122. Has become. That is, the first surface 121 and the second surface 122 are inclined from the bottom wall portion 11 so as to move away from each other as going upward, but the first surface 121 is inclined more than the second surface 122. I have. For example, the inclination angle α of the first surface 121 from the vertical direction can be 1.5 to 4.5 degrees, and the inclination angle β of the second surface 122 from the vertical direction can be 0 to 3 degrees. The inclination angle α of the surface 121 can be 1.1 to 5 times the inclination angle β of the second surface 122. As an example, the inclination angle α of the first surface 121 can be set to 3 degrees, and the inclination angle β of the second surface 122 can be set to 1.5 degrees.

Next, the thin portion 126 will be described. As shown in FIG. 4, a groove (engaging portion) 128 extending over the entire circumference in the circumferential direction is formed at an intermediate portion in the vertical direction of the thin portion 126, and the groove 128 is formed in the groove 128. The projections (engaged portions) 225 formed on the front end are fitted. In the thin portion 126, a notch 129 is formed above the groove 128 from the third surface 123 to the first surface 121 and the second surface 122. The notch 129 is formed so as to cut out the entire third surface 123 and further extend slightly to the first surface 121 and the second surface 122. The shape of a portion of the notch 129 corresponding to the first surface 121 and the second surface 122 is symmetric. Therefore, as shown in FIG. 4, when the container main body 1 is viewed from the front side, the rear side of the container main body 1 can be visually recognized through the notch 129.
