JP 2012-66831 A

  An object of the present invention is to provide an unprecedented new composite container that is easy to use.

Means for Solving the Problems and Effects of the Invention

According to the present invention, there is provided a composite container composed of “a tray container having a storage space with an open top” and “an outer box for storing the tray container”.
In this composite container, the outer box can be slid into and out of the tray container, "the peripheral wall that contacts the tray container from the periphery and frictionally holds the tray container", "bottom wall", and "the bottom wall is facing the bottom wall" Open ".
And the wall part located below the said opening periphery of an outer box is folded in the said storage space of a tray container.

According to the composite container of the present invention having the above-described configuration, the contents accommodated in the tray container in the outer box are pressed against the folded wall and firmly held. As a result, the contents can be protected from vibration during transportation.
Moreover, since the direction from the lower end (base position) of the folded wall to the free end (opening edge) coincides with the tray container removal direction, the folded wall performs the tray container removal operation. There is no hindrance.

Furthermore, according to the present invention, there is provided a composite container with a shrink film formed by covering the composite container with a shrink film.
The welding line for sealing the shrink film includes the “first line extending along the bottom wall of the outer box” and the wall portion of the tray container accommodated in the outer box at a position facing the first line. ”Along the second line” and “a third line extending by connecting positions other than both ends of the first line and the second line”.

  According to the composite container with a shrink film of the present invention having the above configuration, the third line can be brought on the side opposite to the front surface of the outer box. In other words, since the third line can be set avoiding the front of the outer box on which product advertisements, eating methods, and other promotional images are displayed, it is effective that these displays overlap with the lines and are difficult to see. Can be prevented.

  In addition, since the second line extends along the wall of the tray container accommodated in the outer box, there is an appropriate space below the surface of the shrink film, and it is easy to break through here. Opening operation becomes easy. Further, when the bottom wall of the outer box is configured with a movable flap, the first line extends along the movable flap (bottom wall), and therefore, after opening the upper second line, the bottom wall is pushed in. When the operation is performed, the opening of the shrink film and the removal of the tray container can be easily performed as a series of continuous operations.

The figure explaining the tray container and outer box which comprise the composite container which concerns on one Embodiment of this invention. The figure explaining the composite container comprised with the tray container and outer box of FIG. The figure explaining the bottom wall structure of the outer box shown in FIGS. The expanded view of the outer box shown in FIG. The figure explaining embodiment which covers a composite container with a shrink film.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. The composite container of the present invention is configured by accommodating the tray container 10 shown in FIG. 1A in an outer box 50 shown in FIG.
FIG. 2A is a perspective view showing a state in which the tray container 10 and the outer box 50 are combined to form a composite container, and FIG. 2B is a view of this from the side. The tray container 10 stores contents such as instant food here and is sold in a state of being stored in the outer box 50.

<Tray container 10>
The tray container 10 includes a storage space S whose upper portion is open, and includes two flanges 11 at opposing positions around the opening. Water injection lines A and B are provided on the inner surface of the tray container 10, and the water injection lines A and B indicate the water injection amount when the instant food needs to be returned with hot water.
In the illustrated example, two types of water injection lines A and B are provided, but with this configuration, one tray container can be used for two or more types of contents.

<Outer box 50>
The outer box 50 includes a peripheral wall 51 that contacts the tray container 10 from the periphery and frictionally holds the tray container 10, a bottom wall 52, and an opening 53 that faces the bottom wall 52 and allows the tray container to be slidably inserted and removed. Is provided.
In the example shown in the figure, the peripheral wall 51 is composed of four wall portions 51a to 51d, and contacts the periphery of the tray container 10 with an appropriate frictional force and holds it (in FIG. 2b, the wall portion 51d is outside). From the fact that it is slightly swollen, it can be seen that it is held by frictional force). The bottom wall 52 surrounded by the four wall portions 51a to 51d is preferably composed of a movable flap, as will be described next with reference to FIG.
The outer box 50 has an opening 53 at a position facing the bottom wall 52, and the tray container 10 is taken in and out from here.

An arcuate crease 55 is formed on the front wall 51 a of the outer box 50. A wall portion 56 located above the crease 55 and below the opening peripheral edge 53 a is folded into the accommodation space S of the tray container 10. This configuration has the following advantages.
That is, as indicated by a broken line in FIG. 2B, the contents accommodated in the tray container 10 in the outer box 50 are pressed against the folded wall portion 56 and firmly held. As a result, the contents can be protected from vibration during transportation. In particular, when the contents are dry food, the cracking can be effectively prevented.
In addition, as will be described later with reference to FIG. 3, the direction from the base position of the wall portion 56 (the position of the crease 55) toward the free end (opening peripheral edge 53a) coincides with the take-out direction of the tray container 10. The folded wall portion 56 does not hinder the operation of taking out the tray container 10.

  In the present invention, it is sufficient if the area near the upper end of the outer box (in the illustrated example, the wall portion 56) is folded into the storage space S of the tray container. In some cases, the specific shape can be arbitrarily selected.

<Bottom wall 52 of composite container constituted by movable flap>
FIG. 3A shows an enlarged bottom wall 52 of the outer box 50. FIG. 3B shows a state where the central region of the bottom wall 52 is partially opened. FIG. 4 shows a developed view of the outer box 50.
In the illustrated example, the bottom wall 52 includes four movable pieces 52a to 52d. Each of these movable pieces is connected in a movable state to the peripheral walls (wall portions 51a to 51d) via creases. The movable pieces 52a and 52b are bonded to each other to form one movable flap 52A, and similarly, the movable pieces 52c and 52d are bonded to each other to form one movable flap 52C.
In other words, the bottom wall 52 includes two movable flaps 52A and 52C. As a result of such a configuration, when the bottom wall 52 is pressed with a fingertip or the like, the bottom wall 52 is deformed inward (a gap is formed) at its center region as shown in FIG. The tray container 10 accommodated in the container can be pressed with a fingertip or the like. That is, the tray container 10 can be easily taken out by holding the composite container in the state shown in FIG. 2B with one hand and pressing the bottom wall 52 of the outer box 50 with the other hand.

  In order to enable such an extraction operation, the configuration is not limited to using the two movable flaps 52A and 52C shown in FIG. If one or a plurality of movable flaps partially connected to the peripheral wall 51 (for example, via a crease) are provided and each movable flap can be moved inward of the outer box by an external force, a similar extraction operation can be performed. It becomes possible.

  Such a take-out direction of the tray container 10 coincides with a direction from the root position (the position of the crease 55) of the wall portion 56 folded into the container toward the free end (opening edge 53a). For this reason, the folded-in wall part 56 does not disturb the taking-out operation of the tray container 10.

  In the present invention, the bottom wall 52 of the outer box may not be a pushable structure as shown in FIGS. 3 and 4 but may be a general bottom wall that is always sealed. Even in that case, the effect of protecting the contents with the folded wall portion 56 is achieved.

<Merits of the wall and flange of the tray container projecting outward>
As shown well in FIGS. 2A and 2B, when the structure in which the wall portion 56 is folded into the storage space S of the tray container is employed, (a) the flange 11 of the tray container 10 is inevitably removed. It will jump out from the opening edge of the box. In addition, (a) the wall portion constituting the storage space S of the tray container 10 is at least partially exposed to the outside beyond the opening peripheral edge 53 b of the outer box 50.

As a result of the above (a), since the manufacturer logo, product name, and other indications can be prominently arranged on the flange 11 at the time of sales display, a sales promotion effect can be expected.
As a result of the above (a), it can be easily confirmed from the outside that the tray container 10 is contained (exists) inside the outer box 50, which is convenient.

<Configuration with composite film covered with shrink film>
The composite container described above is preferably sold in a state where it is covered with a shrink film. By covering the shrink film, it is possible to prevent foreign matters from being mixed.
FIG. 5 (a) schematically shows such a composite container with a shrink film. The composite container in the shrink film 80 is the same as that shown in FIG. In FIG. 5 (b), only the welding line for sealing the shrink film 80 is conceptually taken out from FIG. 5 (a). FIG. 5C shows this expanded.
The present invention is characterized by a specific configuration of a welding line for sealing the shrink film 80. That is, the welding line is configured to be substantially H-shaped from the following first, second, and third lines 81, 82, 83.

<< First Line 81 >>
A line 81 extending along the bottom wall of the outer box.
<< Second line 82 >>
A line 82 extending along the wall of the tray container accommodated in the outer box at a position facing the first line 81.
<< third line 83 >>
A line 83 extending by connecting positions other than both ends of the first line 81 and the second line 82.

The third line 83 is a sealing line for closing a shrink film arranged so as to wrap a plurality of containers arranged in a posture in which the flanges 11 face each other in the production line, and is a longitudinal line of the plurality of containers arranged in the posture. Extend along the direction.
On the other hand, the first line 81 and the second line 82 facing each other are fusing lines between a plurality of containers arranged in the above-described posture in the production line.
Any of the lines 81, 82, 83 has the same function in that it is a welding line for sealing the composite container with the shrink film 80.

  The fact that the three welding lines 81, 82, 83 are arranged in a substantially H shape as described above has the following merit. That is, as shown in FIG. 5 (a), the third line 83 can be brought on the side opposite to the front of the container (that is, the front of the outer box). In this case, it is possible to prevent the welding line 83 from overlapping the wall 51a on the front side of the outer box (that is, the top surface side where the tray container 10 opens). Since advertisements and eating methods for merchandise, and other promotional patterns are displayed on the front wall 51a, it is difficult to see the display because the welding line 83 overlaps the wall 51a. It can be effectively prevented.

Further, since the second line 82 extends along the wall portion of the tray container 10 accommodated in the outer box 50, there is an appropriate space below the surface of the shrink film, and the second line 82 can be broken open. Simplifies and facilitates opening operations.
Furthermore, when the bottom wall 52 of the outer box is configured with the movable flap (FIG. 3) as described above, the first line 81 extends along the movable flap (bottom wall 52). If the bottom wall 52 is pushed in after the two lines 82 are opened, the opening of the shrink film 80 and the removal of the tray container 10 can be easily performed as a series of continuous operations.
