Description

[0001]
[Industrial application fields]
The present invention relates to a packaging container, and more particularly to a packaging container in which a lid formed by a synthetic resin sheet can be integrated with a container body formed by a synthetic resin sheet by external fitting or internal / external fitting. .
[0002]
[Prior art]
In recent years, various types of packaging containers formed of synthetic resin sheets for fitting the lid to the container body have been proposed, but such packaging containers are always a problem. Is “removing the lid”.
[0003]
That is, it is very difficult to remove the lid made of a thin material called a synthetic resin sheet from the container body without popping out the contents when the container body itself is also formed of a thin synthetic resin sheet. In particular, it should be possible to easily remove the lid while improving the fitting performance to ensure sufficient sealing when fitting the lid to the container body. It's very difficult.
[0004]
For this reason, in Japanese Patent Laid-Open No. 8-183551, for the purpose of “providing a synthetic resin food container that can be easily removed from the container body and is easy to handle”, FIG. 6 and 7, as shown in
“A container body 1 having a fitting portion 1c formed by folding back the outer periphery of the peripheral wall 1b, and a lid 2 having a rising wall surface 2b on the inner side of the edge portion 2a that can be fitted to the fitting portion 1c. The recess 2d is formed at the corner of the rising wall 2b, and the edge of the recess 2d is formed as the wide surface 2e. "
"Food containers" with the structure are proposed.
[0005]
However, in this food container, as shown in FIG. 7 in particular, “the thumb 2 is inserted into the recess 2d and the wide surface 2e is pressed with the fingertip, and the index finger is applied to the lower end of the tip of the edge 2a so that the edge of the lid 2 is Holding the tip of the thumb as a fulcrum and the index finger as an action point, the lower end of the tip of the index finger is pivoted downward, the edge 2a is turned up from the fitting part 1c, and the container body 1 of the lid 2 It is necessary to "release the fitting to" (paragraph 0013 of the above publication), and eventually "hold the edge of the lid 2".
[0006]
As in the conventional food container shown in FIGS. 6 and 7, in order to “grab the edge of the lid 2” and pull it up, the container body side must naturally be held and held with the opposite hand. Thus, a force is applied to the container body formed by the thin synthetic resin sheet. Here, if the lid is suddenly removed, the container body is crushed by the force applied to the container body, and the liquid, particularly the liquid, spills out.
[0007]
Therefore, the present inventor has conducted various studies on how to remove the lid so as not to spill the contents. Rather than letting it come off, you can do a partial removal, i.e. you get a kick out for removal, and you can realize that it is a good result to be able to remove it little by little based on this. It was.
[0008]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described actual situation in a packaging container composed of this type of container body and lid, and the problem to be solved is to allow the lid to be removed without spilling the contents. It is to be.
[0009]
That is, first of all, the object of the invention according to claim 1 is to ensure sufficient sealing when fitting the lid body to the container body, while preventing the leakage of the contents by fingertip operation. Besides as possible out to make a chance of removing the lid, it is possible to manufacture more easily, and to provide a packaging container is to ultimately can be to easily identify Remove lid .
[0010]
In addition, when a child and an object of the invention according to claim 2, in addition capable of achieving invention similar object of the first aspect, the performing the opportunity making off lid even more easily and reliably Ru near to provide a packaging container that can be.
[0012]
[Means for Solving the Problems]
In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the embodiments described later.
“By engaging the engagement protrusion 11 formed on the lid body 20 side with the engaging portion 11 formed on the container body 10 side, the lid body 20 is fitted to the container body 10 outside or inside. And a packaging container formed of a synthetic resin sheet,
A portion of the outer peripheral edge 22 the lower end of the lid 20, laterally in this lower end having substantially the same height, and this allowed out collision such that the outer side than the other portion of the outer peripheral edge 22 lower the projection 23 At the same time, a part of the protrusion 23 is bulged downward from the lower end of the outer peripheral edge 22 of the lid 20 to integrally form the finger locking portion 24,
A packaging container characterized in that a finger can be placed on the finger locking portion 24 and moved upward to make it possible to make a kick to release the fitted state.
It is.
[0013]
That is, the packaging container according to the first aspect includes the container body 10 having the engaging portion 11 shown in FIG. 1 and the lid shown in FIG. 2 having the engaging protrusion 21 engaged with the engaging portion 11. The lid body 20 is integrated and used by fitting the lid body 20 to the container body 10 by external fitting or internal / external fitting. In addition, the packaging container is formed by integrally forming a finger locking portion 24 on a part of the lid body 20, and when the finger locking portion 24 is hooked and caused, A part of the fitting with respect to the container body 10 is released, so that “creeping” for removing the lid 20 can be performed.
[0014]
In particular, as shown in FIGS. 2 and 4, the finger locking portion 24 of the lid 20 is opened above the lower concavity. Since the locking portion 24 enters the lower finger locking portion 24, the stacking can be ensured and also serves to prevent misalignment after stacking.
[0015]
The finger locking portion 24 of the lid 20 is formed at the same time as the lid 20 is molded from a synthetic resin sheet, and can be easily formed by a general vacuum or pressure molding method. It has become. That is, as shown in FIG. 2A, the finger locking portion 24 forms a protruding portion 23 while leaving a part of the synthetic resin sheet that is normally cut off from the outer peripheral edge 22. A part of the portion 23 can be formed by, for example, extruding by a protrusion formed on the upper mold or by drawing it into a recess formed on the lower mold by vacuum.
[0016]
Also, the finger engaging portion projecting portions 23 to 24 are formed, it is to form a substantially same position as the outer periphery 22, ing to facilitate the cut off by knife immediately after molding.
[0017]
Now, when the lid 20 having the finger locking portion 24 as described above is externally fitted or fitted inside and outside with respect to the container body 10, the finger locking portion 24 is shown in FIG. As shown in FIG. 4, it is hung from the protruding portion 23 on the lid 20 side in a state in which a gap that allows human fingers to be inserted is formed between the upper side surface on the container body 10 side. Therefore, when the lid 20 is removed, a finger is put inside the finger locking portion 24 as shown in FIG. 4, and the finger locking portion 24 is pulled up as shown in FIG.
[0018]
At this time, the protruding portion 23 formed with the finger locking portion 24 is continuous with the outer peripheral edge 22 of the lid 20 and is integrated with a part of the outer peripheral edge 22. By pulling up the locking portion 24 shown in FIG. 5, a part of the fitting of the lid body 20 is removed, and a kick for opening the lid body 20 is made. In addition, the finger locking portion 24 can be pulled up with one finger, so that it is not necessary to apply a large force on the container body 10 side, particularly a large force that causes the contents to pop out when the lid 20 is opened. As a result, the contents of the liquid or the like in the container body 10 do not pop out when a sparkle is made.
[0019]
As described above, the opening of the lid 20 is made, that is, if the engagement state of the engagement protrusion 21 on the lid 20 side with respect to the engagement portion 11 on the container body 10 side is partially released, The entrance and exit of air into the container body 10 is free. Therefore, after that, the remaining fitting state is released, that is, the lid 20 is removed. However, since the flicker has already been completed, the opening operation may be performed literally as “flicker”. This work can be done with very light force because the air can be taken in and out of “Kikake”, and the entire packaging container will not be accidentally shaken and the contents will not be spilled. .
[0020]
In addition, the lid 20 removed from the container body 10 may be placed on a table or the like. At this time, the finger locking portion 24 protrudes downward from the lower surface of the lid 20. The entire lid 20 is supported diagonally on the table, with the finger locking portion 24 as a support. In other words, the presence of the finger locking portion 24 that protrudes downward from the back surface of the lid body 20 prevents the lid body 20 from being placed on the table and is attached to the back surface of the lid body 20, for example. The melted ice cream that is stored does not adhere to the table.
[0021]
Therefore, the packaging container according to the first aspect of the present invention can sufficiently secure the sealing property when the lid body 20 is fitted to the container body 10 and of course the lid while preventing leakage of the contents by fingertip operation. It is possible to make a kick off the body, and finally the lid can be easily removed.
[0022]
In order to solve the above-mentioned problem, the means taken by the invention according to claim 2 is as follows.
"Some of the engagement projection 21, just inside the finger engaging portion 24, that forms the shape of the near-engaging projections 21a for engagement with the engaging portion 11 of the container body 10 side"
It is.
[0023]
That is, the packaging container according to claim 2 is a part of the engagement projection 21, that is, the proximity engagement projection 21 a on the lid 20 side, immediately inside or adjacent to the finger locking portion 24. The proximity engagement projection 21a can maintain the fitting state of the lid 20 with respect to the container body 10, and the proximity of the finger lock 24 when the finger locking portion 24 is pulled up by one finger. The engagement state at the engagement protrusion 21a can be released more easily.
[0024]
Therefore, since the packaging container according to claim 2 has the proximity engaging projection 21a formed in the immediate vicinity of the finger locking portion 24, the opening operation of the finger locking portion 24 can be performed more easily. 20 can be removed without spilling the middle part of the container body 10.
[0026]
Further, the packing wear container according to the present invention described above, the position of the projecting portion 23 forming the finger engaging portion 24, which was set to be substantially equal to the outer peripheral edge 22 of the cover 20, thereby, After the mold forming, the projecting portion 23 is cut out with the blade, and the outer peripheral edge 22 can be formed at the same time. In particular, the lid 20 constituting the packaging container can be manufactured very easily.
[0027]
Therefore, the packaging container according to the present invention, a portion of the outer peripheral edge 22 of the cover 20, be made as the finger engaging portion 24 formed to the protruding portion 23 is partially formed The projecting portion 23 can be cut out and the finger locking portion 24 can be easily formed without greatly changing the structure of the cutting device currently in use. It is something that can secure the sex.
