Description

[Detailed Description of the Invention] The present invention relates to an improvement in a packaging container that makes it possible to separately store items with different properties, such as tokoroten or agar and sauce.

As an example of a conventional packaging container of this kind, for example,
There is Misaki Utility Model Registration Application No. 03918 (Utility Model Application Publication No. 154684 of 1982).

In the above application, as shown in FIGS. 1 and 2, the flange 2a of the inner lid 2 is overlapped with the opening flange 1a of the container body 1, and the upper lid body 3 is further overlaid on top of the dropped inner lid. The three parts are glued together at the periphery, and a part of the corner of the drop-in lid 2 is formed into a shallow bottom 2b, a slit hole 4 is formed therein, and the drop-in lid M2 and the container are attached at a position symmetrical to the slit hole. Easily peelable portions 5 are formed in the flange portions 1a and 2a between the main body 10, and 2c is a deep bottom and 2d is an inclined surface.

Therefore, items with different properties are stored separately in the container body 1 and the drop-in lid 2, respectively, so that they can be transported together to prevent them from mixing with each other during transport. When the seal is completely sealed and the consumer opens the package as shown by the chain line in FIG. For example, the container body 1 moves to the side and falls into the container body 1 through the slit hole 4 provided in the shallow bottom 2b.
When storing jelly inside, it is so that it can be eaten as cream jelly.

However, in the above-mentioned known packaging container, when the container turbulently moves, the liquid located at the deep bottom 2c moves to the shallow bottom 2b side due to the turbulent movement, and drips into the container body 1 from the slit hole 4. It is possible for the contents in the lid 2 and the contents in the container body 1 to be kept completely separated during dropping, and it is also possible that the contents contained in the container body 1 contain moisture or liquid. If the product is a liquid, it should be in contact with the back surface of the upper lid body 3 and the back surface of the drop-in inner lid 2, and when the container body 1 is filled and stored, moisture or liquid should be It enters the deep bottom 2c from the slit hole 4 through the shallow bottom 2b, and it is also impossible to keep the contents in the inner lid 2 and the contents in the container body 1 completely separated. It is.

Therefore, when storing an article 6 containing moisture or an article 6 mixed with liquid in the container body, a space 7 is created between the upper surface of the article 6 and the drop-in lid 2, as shown in FIG. must be accommodated to form.

However, the existence of the above-mentioned space causes the articles in the container body 1 to constantly come into contact with air, causing deterioration due to oxidation.

This invention deals with how the packaging container is turbulent.1. However, even if a liquid or an article mixed with a liquid, or an article containing moisture is contained in both or one of the drop-in lid and the container body, it is also possible to store the above-mentioned article in the container body. Even when filled and stored, the items in the drop-in lid and the items in the container body are held completely separate and do not mix, and the items in the container body are held in the drop-in lid. By being able to fill and store items in close contact with the back surface of the flange and the back surface of the drop-in part, it is possible to exclude air from inside the container body and seal it, thereby preventing oxidative deterioration of the items stored in the container body. It is an object of the present invention to provide a packaging container which can prevent such problems as much as possible and which is extremely easy to operate.

The present invention will be described below with reference to the embodiments shown in the drawings.

As shown in FIGS. 3 to 17, the container body 11 is made of polyethylene or styrene plastic, and has an opening 11a having a substantially rectangular shape in plan and a flange 11b projecting horizontally outward from the opening. ing.

Drop the inner lid 12 from the opening 11a to the container body 11.
and a flange 1 that projects horizontally from an upper opening 12b of the depressed portion and is superimposed on the flange llb of the container body 11.
2c is formed.

The inner corner 12d of one corner of the flange 12c is
A liquid circulation groove 12g extending from the outer portion 12e to the front side 12f is formed.

The upper lid 13 is made of polyethylene, styrene plastic, aluminum foil, a laminate of aluminum foil and styrene plastic film, etc., and is placed on the inner lid 12 and overlapped with the flange 12c. Form into shape and size.

After storing honey and other sauces in the lowering inner lid 12, the upper lid 13 is placed on the lowering inner lid 12, and the flange portion of the lowering inner lid 12 excluding the liquid circulation groove 12g, that is, the flange 12c. A lid body 14 is formed by sealing an outer corner 12e of the outer corner 12e, a flange 12c continuous with the outer corner, and the upper lid 13 using an adhesive or other appropriate means.

When the lid body 14 is lowered, the liquid flow groove 12g formed in the lid 12 is inserted into the flange 12 as shown in FIG.
c, from the inner corner 12d to the front 12f of the outer corner 12e, and between the outer corner 12e and the outer corner 12e
In other words, the flange 12c between the tip of the groove 12g and the flange 12c continuous with the flange 12c may be sealed 17 to the upper lid 13 as described above.
As shown in the figure, the liquid circulation groove 12g is communicated from the inner corner 12d to the outer corner 12e of the flange 12C, and the adhesive 17, etc. is filled near the outer corner of the groove 12g, and the upper surface of the adhesive 17, etc. In some cases, the flange 12c continuous to this is sealed to the upper lid 13.

A breakage peeling groove 15 is formed on the side of the lid body 14 where the liquid circulation groove 12g is formed, crossing over the groove 12g.

The breakage peeling groove 15 is shown in FIGS. 8, 9, 11, and 1.
As shown in FIG. 2, the upper lid 13 may be made of hard polyethylene or the like and formed on the upper surface thereof, or the container body 11 may be made of hard polyethylene as shown in FIGS. 14, 15, 16, and 17. It is formed from polyethylene, etc., and its flange llb
In some cases, it may be provided.

According to the present invention, the lid body 14 is separated from the container body 11 by cutting through the breakage peeling groove 15 described above and peeling it off in the direction of the arrows in FIGS. 9, 12, 15, and 17.

Since the breakage peeling groove 15 is formed across the liquid flow groove 12g, the breakage causes the liquid flow groove 12 to
g, the depressed portion 12a is communicated with the outside air.

Therefore, by pressing the lid 14 in the direction of the arrow as shown in FIG.
It is poured into the container body 11 through the process.

As described above, in the present invention, the liquid collected in the drop-in part of the lid during dropping is communicated with the liquid flow passage, but the liquid flow passage is completely sealed by the upper lid, so that the liquid collected in the drop-in part of the drop-in lid is communicated with the liquid flow passage. Since the liquid inside the drop-in part is completely isolated from the outside, no matter how turbulent the packaging container is, the present invention prevents liquid from entering inside the drop-in lid and/or inside the container body. Even if mixed items or items containing moisture are stored, or even if the container body is filled with the above items, the items in the drop-in lid and the items in the container body will be separated. The items inside the container body can be held in a completely separate state without mixing, and the items inside the container body can be filled and stored in close contact with the back of the flange of the drop-in lid and the back of the drop-in part. , it is possible to exclude the air inside the container body and seal it, which not only prevents oxidation and deterioration of the items stored in the container body as much as possible, but also allows the lid to be removed by simply cutting it from the breakage peeling groove. Since it is possible to separate the body and open the liquid flow path provided in the lid, the operation is extremely simple.
