[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container for selling various foods, a packaging container for take-out or catering lunches, etc., and more particularly to a packaging container provided with a separate fitting lid from the container body. is there.

[0002]

2. Description of the Related Art This type of packaging container is made of polystyrene,
Such as polypropylene, polyethylene, polyvinyl chloride,
A semi-rigid or rigid, solid or foamed, single-layer or laminated plastic sheet is used as a material, and the desired sheet shape is set in advance by an appropriate sheet forming method such as vacuum forming, pressure forming, and hot press forming. It is obtained by molding.

[0003] There is also a container in which water- and oil-resistant paper is formed into a container by sheet forming using a hot press or the like. There is also a thin injection molded container made of plastic.

[0004] The packaging containers include those without a lid and those with a lid. Further, there are a container with a lid in which the lid is separated separately from the container main body, and a type in which the lid is connected to the container main body by a hinge portion so as to be freely opened and closed.

[0005]

In the case of a container with a lid, it is a common practice to put an article on the lid and then close the lid with adhesive tape or staples to prevent the lid from being opened carelessly. In the case of a container to be filled, there are safety and hygiene problems, and it takes time to stop the lid.

In order to easily and securely fix the lid to the container body without using an adhesive tape or a staple, the edge of the container body is framed and the outer peripheral edge thereof is bent slightly downward. A frame-shaped overhanging edge is formed on the edge of the lid so as to cover and extend from the upper surface to the side surface of the frame-like overhanging edge of the container main body. Corner)
In addition, a projection formed so as to be hooked on a lower edge of a downwardly bent edge of the frame-shaped overhanging edge on the container body side is provided particularly as a food packaging container.

The above-mentioned lid fitting structure is convenient for the supplier and distributor because it is easy to fit and fixed securely, but it is difficult to remove it on the consumer side and it takes time to open the lid. In particular, when the material of the container body and the lid is thin, it is difficult to open the lid because the container body and the lid cannot be firmly grasped. Moreover, both the lid and the container body must be handled, which is troublesome.

[0008] For the purpose of solving the above inconvenience, the present applicant has
First, Japanese Utility Model Application Laid-Open No. 62-177612 and Japanese Utility Model Application Laid-Open No. 63-177612.
-94106 was proposed. The above proposal is particularly effective in the case where the length of the container body is low, that is, in the case of a tray, and enables the lid to be easily and quickly opened.However, the present invention further improves the An object of the present invention is to provide a packaging container with a lid that is easy to open even if the container body and the lid are formed of a thin material, as well as the tray type.

[0009]

In order to achieve the above object, the present invention provides a container body 1 having a frame-shaped overhanging edge 3 whose outer peripheral edge 3a is bent downward, and a frame-like overhanging edge 3 of the container body 1. And a lid 2 having a frame-shaped overhanging edge 4 which covers over from the upper surface to the side surface of the container body 1. The formed packaging container with a lid is characterized in that it is configured as follows.

[0010] That is, the position in the diagonal direction of the container body side.
A frame shape projecting edge 3 of the corner that location, when closing the lid 2 under <br/> rising obliquely downward by being pressed by the frame-shaped projecting edge 4 of the lid 2, is pulled laterally pinching the container A part is extended slightly downward in the horizontal direction so as to disengage the lid 2 from the lower edge of the frame-shaped overhanging edge 3 of the main body 1 and lift the lid 2 up.
This is provided with the formed knob 5.

[0011]

When the lid 2 is placed on the container body 1, the frame-shaped overhanging edges 3 and 4 overlap with each other, and the frame-like overhanging edge 4 of the lid 2 pushes the knob 5 to face obliquely downward . Further, by strongly pressing the lid 2, particularly the peripheral portion of the projection 4a, the projection 4a is hooked on the lower edge of the frame-shaped overhanging edge 3 of the container body 1, and the lid 2 is fixed.

When the container with the lid is placed on a table or a lap, and the knob 5 is pinched and pulled in the lateral direction, the frame-shaped overhanging edge 3 of the container body 1 extends, and the projection 4a of the lid 2 becomes the knob 5 And the lid 2 is lifted off the lower edge of the frame-shaped overhanging edge 3 of the container body 1.

[0013]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a packaging container with a lid according to the present invention. The packaging container shown in FIG. 1 is a so-called square container, 1 is a container body, and 2 is a lid that is shallower than the container body 1. Frame-shaped projecting edges 3 and 4 are formed on the peripheral edges of the container body 1 and the lid 2 respectively.

The frame-shaped overhanging edge 3 of the container body 1 is shown in FIG.
As shown in the figure, the outer peripheral edge 3a is bent downward. The frame-shaped overhanging edge 4 of the lid 2 is formed so as to fit over the frame-like overhanging edge 3 of the container body 1 from the upper surface to the side surface.

The inwardly projecting portion 4a formed mainly at the corner of the frame-shaped overhanging edge 4 of the lid 2 is
The lid 2 is stopped by being hooked on the lower edge of the outer peripheral edge 3a of the frame-shaped overhanging edge 3 (see FIG. 2).

As shown in FIG. 1, a pair of corner-shaped tongue-shaped knobs 5 located in a diagonal direction of the frame-shaped overhanging edge 3 of the container body 1 are integrally laterally extended from the downward outer peripheral edge 3a.
Partially extended downward is provided. The pair of knobs 5 may be provided symmetrically near the center of each of two corresponding sides of the frame-shaped overhanging edge 3 of the container body 1.

When the lid 2 is closed, the above-mentioned knob 5 is moved to the position shown in FIG.
As shown by the solid line in FIG.
Point diagonally downward . When the lid 2 is opened, the knobs 5 at the symmetrical positions are pinched and pulled outward as shown by the chain line in FIG. Then, the vicinity of the frame-shaped overhanging edge 3 of the container body 1 connected to the knob 5 extends and the protrusion 4a of the lid 2 is pushed up, so that the protrusion 4a with respect to the lower edge of the downward facing outer edge 3a of the container body 1 is raised. The engagement is released, and the lid 2 is opened as if to float as shown in FIG. That is, the lid 2 can be removed from the container body 1 without putting any hand on the lid 2.

[0018]

[0019]

Since the packaging container with a lid according to the present invention has the above-described structure, it has the following various effects.
When closing the lid, the lid can be closed in the same manner as a conventional container with a locking structure, that is, by a simple operation of putting the lid on the container body and pushing.

When the lid is opened, the lid can be easily unlocked by simply grasping the knob on the container body side and pulling outward, and the lid can be opened. That is, even if the fitting of the frame-shaped overhanging edges is considerably strong, they can be easily removed. Therefore, by fitting the frame-shaped overhanging edges of the lid and the container body around the entire circumference to strengthen the fitting, it is possible to prevent the lid from being detached or exuding from the contents during transportation or handling.

Since it is not necessary to hold the lid to open the lid, the lid can be opened while the container is placed on a table or a knee. When the lid is opened, the container is stable and the contents are There is no risk of accidentally spilling or jumping out. Therefore, even if the container body is a tray-shaped container that is difficult to hold by hand, it can be opened stably.

When the lid is opened, the knob part used when the lid is closed is pushed downward by the frame-shaped overhanging edge of the lid, so that the knob part is not obstructed when packing or displaying. And it will not look bad when displayed.

In the case of a container having a corner such as a rectangular container or a polygonal container, the knob portion of the container body can use the overhanging portion of the corner portion, so that the material sheet for molding the container body is wasted. Does not occur.
