Description

TECHNICAL FIELD The present invention relates to a synthetic resin packaging container used for packaging side dishes, box lunches, desserts, sweets, and other various foods that are displayed and sold in food sections such as supermarkets and convenience stores.

Various foods such as side dishes, boxed lunches, and desserts displayed in the food section of supermarkets, for example, are Western-style side dishes such as steak and Chinese dishes such as sweet and sour pork. It is sold in a packaging container with a transparent lid that has an appearance and shape that brings out a sense of volume and makes it look appetizing.

As a packaging container used for the display and sale of such food, for example, a container for storing an assortment of multiple types of food such as hors d'oeuvres, in order to increase the amount of food that can be stored, the interior is divided into multiple compartments with partition walls. A substantially cylindrical pedestal is formed in the central part of the partitioned dish-shaped container body, and a small dish-shaped inner container is placed and supported on this pedestal, that is, a food storage portion raised in the container body is formed. The food is stored in each of the compartments of the container body and the inner container, covered with a substantially dome-shaped transparent lid body, and the peripheral edge portion of the lid body is loosely fitted to the outer surface of the peripheral stepped portion of the container body. There is known a form in which food is packaged by attaching it to a container (see, for example, Patent Document 1).

In addition, when a person who purchases food picks up a food packaging container displayed on a table or shelf, or displays packaging containers in multiple layers on a display table, it is necessary to cover the container body. In order to prevent the lid from being dented by the load received from above, there is known a form in which a stepped protrusion is provided around the top surface of the lid that is rectangular in plan view to make it difficult to deform (for example, See Patent Document 2).

In a state in which food is packaged in a packaging container, that is, in a state in which the food is contained in the container body, and the lid is placed on top of the food and attached to the container body, the lower surface of the top surface of the lid is housed in the housing portion of the container body. However, due to carelessness when putting the lid on, or vibrations when carrying the packaging container, the stored food may come into contact with the lid.
If part of the food, sauce, or juice is stuck to the lower surface of the top surface of the lid, the appearance of the packaged food will be significantly deteriorated, and not only will it not look appetizing, but it will also make the food look unclean. It can be given to those who are doing it.

Therefore, in the work of packaging food, when attaching the lid to the container body, instead of covering the container body by pressing the top surface of the lid by hand, the lid is protruded around the top surface. The container body is covered from directly above while being held by a finger on the peripheral edge of the lid, and in particular, a raised storage part is provided in the container body described above, and a dome-shaped lid is placed above the storage part where food is piled high. or when the food contained in the container contains sauce or cream that easily sticks to it, carefully operate the lid so that the bottom surface of the top surface of the lid does not come into contact with the food contained in the container body. The lid is attached by fitting the peripheral edge of the lid to the peripheral edge of the container body.

As described above, the lid is attached to the container body by placing the lid on the container body while holding the peripheral edge of the lid with a finger. It is a portion that is easily deformed because the width is narrow and the lid itself is thin.
Therefore, when attaching the lid to the container body, the peripheral edge of the lid may be crushed or deformed by strongly gripping the peripheral edge with the fingertips or strongly pressing against the upper surface of the container body. was there. Even with the lid body having a form in which a reinforcing projecting portion is provided around the top surface portion as described above, the peripheral edge portion thereof has low strength and is a portion that is easily deformed.

The purchaser of the food removes the lid from the packaged container by grasping the peripheral edge of the lid covering the container body and pushing it upward. Concentrate on the peripheral edges of the body.
I bought it because there was no food on the top of the lid and the packaged food looked delicious. Now that I know, even if the food I purchased was actually delicious, I couldn't help but feel disappointed that I had purchased an imperfect product, so I thought about forgoing the next purchase of that food. It's not strange.

In view of such problems of the prior art, the present invention provides a packaging container comprising a container body and a transparent lid, wherein the lid is operated when the lid is placed on or removed from the container body. The strength of the peripheral edge of the lid body, which is a part where a person's gaze is concentrated and is a part to be held by hand with fingers, is increased to prevent it from being crushed, and this part is also decorated to improve the appearance of the packaging container. To make the food contained in the container look better.

In order to solve the above problems, the present invention provides a packaging container having a container body provided with a food storage portion on the top surface and a transparent lid covering the top of the container body,
The container body has a folded portion at the upper portion of the peripheral side wall surrounding the accommodating portion,
The lid has an outward projecting portion at the lower portion of the peripheral side wall, and is attached to the container body by engaging the outward projecting portion with the edge of the folded portion of the container body,
The outer projecting portion of the lid includes an outer folded surface portion bent outward from the lower end of the peripheral side wall of the lid, a lower folded surface portion bent downward from the lower end of the outer folded surface, and a lower folded surface portion bent downward from the lower end of the outer folded surface. and an engaging portion with the container body provided on the lower side of the face portion,
A first relief-shaped pattern is formed in the plane of the lower folded surface portion.

According to this method, the food to be packaged is placed in the storage portion of the container body, the lid body is held with a finger on the end of the outward projecting portion that is the peripheral edge of the lid body, and the food is placed on the container body from above. The cover is placed on the container main body, and the engaging portion of the outward projecting portion is engaged with the edge of the folded portion provided on the upper portion of the peripheral side wall of the container main body to attach the cover to the container main body. can be used to package food.
To remove the lid attached to the upper surface of the container body, put a finger on the edge of the outward projecting portion and pull the edge so that it spreads outward to engage with the edge of the folded portion of the container body. is released, and the lid body is pulled up as it is.

Since a relief pattern is formed on the surface of the outwardly projecting portion of the lid, which is held with a finger when the lid is attached to or detached from the container body, the strength of the outwardly projecting portion is increased. Even if the outwardly projecting portion is grasped and pushed toward the container body or pulled outward in the course of the attaching/detaching operation, the outwardly projecting portion is less likely to be crushed, and the food-packaged container has a good appearance. can be maintained.

In addition, when the lid is attached to the container body, the relief pattern formed in the plane of the bottom folded surface of the outwardly projecting portion is exposed, and the peripheral edge of the packaging container is thick and three-dimensional. The appearance of the packaging container is improved, and the texture and flavor of the food stored in the container can be seen to be of high quality.

In the packaging container configured as described above, in addition to the first relief-shaped pattern, a second relief-shaped pattern different from the first relief-shaped pattern is formed in the plane of the outer folded surface of the lid. can be assumed.

According to this, by forming the relief-shaped pattern on the outer folded surface portion inside the lower folded surface portion on which the first relief-shaped pattern is formed, the strength of the outwardly projecting portion of the lid body is further increased, and The overhanging portion is less likely to be crushed.
In addition, when the lid is attached to cover the container body, the outer folded surface part overlaps the upper part of the peripheral side wall of the container body, and the relief pattern formed in the surface is exposed. Together with the fact that the upper surface of the side wall can be seen through, the peripheral edge of the packaging container is decorated with the first relief-shaped pattern and the second relief-shaped pattern, giving a luxurious appearance. The appearance of the container is improved, and the texture of the food contained therein can be enhanced.

Here, the first and second relief-shaped patterns formed on the outwardly projecting portion of the lid means that the surface of the outwardly projecting portion of the lid is made uneven so that the surface appears to be raised. It refers to the pattern that has been set. This includes patterns, shapes, symbols, characters, combinations thereof, etc. formed by making the surface of the outward projecting portion uneven.
A relief-shaped pattern is a pattern in which convex or concave portions are intermittently arranged along the circumferential direction in the plane of the outward projecting portion, or arranged in rows. Decorative patterns that imitate symbols and letters three-dimensionally are applicable. The first relief-shaped pattern in the embodiment described later is a decorative pattern that three-dimensionally imitates a "rope" or a "log" by looking down on the entirety of the lid that is formed with the unevenness.

In the packaging container configured as described above, the first relief-shaped pattern formed on the lower folded surface portion of the lid includes a trough formed by recessing the surface inward and outward from the upper end to the lower end of the lower folded surface portion. A slanted vertical striped pattern in which protruding peaks are arranged alternately and slanted to each other, and is characterized in that it is formed over the entire circumference of the lower folded surface.

According to this, the slanted vertical striped pattern in which the troughs and peaks, which are the first relief pattern, are alternately and slanted is provided over the entire circumference of the lower folded surface of the outwardly projecting portion of the lid. The strength of the entire periphery of the outward projecting part is increased to prevent crushing, and the entire outward projecting part is decorated with a continuous and uniform pattern, so that the appearance of the packaging container can be improved.
Even if the inclined vertical striped pattern, which is the first relief pattern, is formed not over the entire circumference of the lower folded surface but partially within the surface, the strength of the outward projecting portion is increased. Instead of the inclined vertical striped pattern, a first relief-shaped pattern different from this may be provided over the entire circumference of the lower folded surface.

Further, in the packaging container having the above configuration, at least one lid is attached to the container main body in a portion where the second relief-shaped pattern is not formed in the plane of the outer folded surface of the lid. It is characterized by the formation of push-down ribs for pushing down the body.

According to this, when the lid is attached to the container body, the top surface of the container body is covered with the lid body, and a finger is put on the pressing rib formed in the plane of the outer folding surface portion to push it downward. The inwardly bent portion of the lid engages with the edge of the folded portion provided on the upper portion of the peripheral side wall of the container body, so that the lid can be easily attached to the container body. In addition, since the lid can be attached by pushing down the push-down rib, it is possible to reduce the occurrence of crushing of the outwardly projecting portion caused by operating the lid by holding the outwardly projecting portion.

Further, in the packaging container having the above configuration, the folded portion of the container body has an inclined surface portion that inclines upward from the upper end of the peripheral side wall and protrudes outward from the container body, and a lower portion that is bent downward from the end of the inclined surface portion. On the other hand, the outer folded surface portion of the lid is formed so as to be inclined upward from the lower end of the peripheral side wall and protrude outward from the lid, and the lid is attached to the container body. When the lid is closed, the outer folding surface portion of the lid body can be provided so as to overlap the inclined surface portion of the container body.

According to this, when the lid is placed on the upper surface of the container body, the lid can be pushed downward by putting a finger on the end of the outwardly projecting portion or by putting a finger on the push-down rib to push down the container. The outer folded surface portion of the lid overlaps the inclined surface portion of the main body, and the inwardly bent portion of the lid engages the edge of the folded portion provided on the upper portion of the peripheral side wall of the container body, thereby attaching the lid to the container body. can be installed.
In this way, the lid is attached by overlapping the lower folded surface portion, which is a part of the outward projecting portion of the lid body, with the inclined surface portion, which is a part of the peripheral side wall of the container body. Compared to a form in which the outer projecting part entirely overlaps the entire upper part of the peripheral side wall of the container body so that the lid can be attached, the lid is attached to the container body. Since the contact area is small, the outwardly projecting portion is less likely to be crushed when the lid is operated by holding the outwardly projecting portion.
Further, in a state in which the lid is attached to the container body, the lower folded surface portion of the lid body is superimposed on the inclined surface portion of the container body, and the relief pattern formed on the lower folded surface portion is inclined inward along the inclined surface portion. and express it. At food stores, foods contained in packaging containers are often placed on display shelves that are illuminated so that they can be easily seen. When the relief-shaped pattern is exposed in an inclined direction, the illumination light is incident on the relief-shaped pattern, and the degree of diffused reflection increases, and the relief-shaped pattern looks more gorgeous, and the appearance of the packaging container is improved. It can create an appearance that makes the food contained in it look like it is of high quality and luxury.

Further, in the packaging container having the above configuration, the container body is formed by partitioning the container body surrounded by the peripheral side wall into a plurality of partition walls arranged therein, and the upper inner surface of the peripheral side wall is provided with the above-mentioned A third relief-shaped pattern is formed, the pattern being different from the first and second relief-shaped patterns.

According to this, if a relief-shaped pattern is formed on the upper inner surface of the peripheral side wall of the container body, the illumination light that enters the container body through the transparent lid while the lid is placed on the container body. hits the relief-shaped pattern formed on the inner surface of the upper part and is diffusely reflected. The appearance of the container can be further improved by creating a luxurious appearance.
Similarly to the first and second relief patterns formed on the lid, the third relief-shaped pattern formed on the inside of the container body is also formed by making the inner surface of the container body uneven so that the inner surface has a convex shape. It is formed in a visible pattern, and includes patterns, shapes, symbols, characters, combinations thereof, and the like.

The third relief-shaped pattern formed in the container body is different from the first and second relief-shaped patterns formed in the lid in order to enhance the decorativeness of the pattern provided on the surface of the packaging container. Although it is preferable to provide the third relief-shaped pattern, the third relief-shaped pattern may be provided in the same pattern as the first or second relief-shaped pattern, or may be provided in a different pattern but with the same or similar motif, to create a sense of unity. The container body and the lid may be decorated with a pattern that is recognized as having
Also, the first and second relief-shaped patterns formed on the lid may be provided with the same pattern or pattern with the same motif that is recognized as having a sense of unity.

The packaging container of the present invention can be formed by thermoforming such as thermoforming such as pneumatic or vacuum forming using appropriate plastics such as oriented polystyrene, impact-resistant polystyrene, polypropylene, and polyethylene terephthalate. The lid is preferably molded using transparent polypropylene, biaxially oriented polystyrene, polyethylene terephthalate, or the like. Any other molding material may be used and any molding method may be used. The material and molding method of the container body and the lid may be the same or different.
In addition, the outer shape of the packaging container should be provided in an appropriate shape, such as a polygonal shape such as a square or a pentagonal shape when viewed from above, or a circular shape or oval shape when viewed from above, depending on the type of food to be accommodated and the amount of food to be served. can be done.

According to the packaging container of the present invention, a relief-shaped pattern is formed on the surface of the outward projecting portion of the lid that is held by a finger when the lid is attached to or detached from the container body. The strength of the outward projecting portion is increased, the outward projecting portion is less likely to be crushed, and the appearance of the container in which the food is packaged can be maintained in good condition.
In addition, when the lid is attached to the container body, a relief pattern appears on the surface of the lid, and the peripheral edge of the packaging container is decorated with a thick three-dimensional pattern design. It is possible to create an appearance that makes it possible to perceive that the texture and flavor of the food contained in the container are of high quality.
