2. Description of the Related Art Conventionally, in a refrigerator which is one of storages, a door pocket case is attached to the inside of a door to form a door pocket. This door pocket case is usually formed of plastic, and in particular, a center gate method in which a plastic material is injected from a substantially central portion of the bottom portion is employed for forming the door pocket case.

[0003] However, in the door pocket case formed by the center gate method, the solidification of the injection portion is slower than that of the other portions, and distortion tends to remain.
In view of the fact that the mechanical strength is low, a projection 1 as shown in FIG. 7 is further formed on the inner surface of the injection portion to increase the thickness of the injection portion 2 and increase the mechanical strength. Increasing the strength has been performed.

[0004]

However, in the case where the convex portion 1 is formed on the inner side surface portion as described above, articles stored in the door pocket case easily hit the convex portion 1,
In particular, when a hard and heavy article such as a bottle or can hits, the impact is applied to the injection portion 2 and cracks or the like are easily generated.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a door pocket case of a storage which can be used without causing cracks or the like in a plastic material injection portion.

[0006]

In order to achieve the above object, in a door pocket case of a storage according to the present invention,
The first feature is that the inner side surface of the plastic material injection part near the center of the bottom is recessed from the peripheral surface. In the door pocket case of the storage of the present invention, the second
Further, the recess is connected to the inner bottom surface without any step.

Third, the door pocket case of the storage according to the present invention is characterized in that a projection is formed on the outer surface of the injection portion. Fourth, the door pocket case of the storage according to the present invention is characterized in that the convex portion is formed in a ring shape surrounding the injection portion.

[0008]

According to the first means, the article stored in the door pocket case does not hit the injection portion, so that no impact is applied to the injection portion. Further, according to the second means, the dent is easily cleaned, and no dirt or dirt is accumulated.

According to the third means, it is possible to reinforce the injection portion of the door pocket case without hitting articles stored in the door pocket case. According to the fourth means, it is possible to reinforce the injection portion of the door pocket case without causing hitting of the articles stored in the door pocket case and using less material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a door pocket case of a refrigerator will be described below with reference to FIGS. First, FIG. 4 shows an overall configuration of a refrigerator, in which a refrigerator compartment 12 is provided in an upper portion of a main body cabinet 11, an upper freezing compartment 13 and a lower freezing compartment 14 are provided in a middle portion, and a vegetable compartment 1 is provided in a lower portion.
The refrigerator compartment door 16, the freezer compartment upper door 17, the freezer compartment lower door 18, and the vegetable compartment door 19 are provided at the front open ports of each of the compartments 12 to 15.

Among the doors 16 to 19, in particular, in the refrigerator compartment door 16, various door pocket cases 20 to 26 shown in FIG.
To 33 are formed. FIG. 6 shows a door pocket case 26 of the door pocket case 26.
As represented by the above, the above-mentioned door pocket cases 20 to 26
Is formed by a center gate method in which a plastic material is injected from a substantially central portion of the bottom, and from this relation, an injection portion 34 is provided at a substantially central portion of the bottom.

A recess 35 shown in FIG. 1 is formed on the inner side surface of the injection portion 34 of the door pocket case 26 so as to be recessed from the surrounding surface. It communicates with the inner bottom surface of the case 26 without any step. A convex portion 36 is formed on the outer surface of the injection portion 34 of the door pocket case 26. In particular, the convex portion 36 has a ring (a circular shape) surrounding the injection portion 34 as shown in FIG. Rib).

In addition, on the outer surface of the injection portion 34 of the door pocket case 26, a gentle mountain-shaped convex portion 37 is formed which is located inside the convex portion 36. In addition, the door pocket case 26 is provided with a very fine unevenness 38, such as frosted glass, on the entire outer surface of the bottom portion, and otherwise is entirely transparent.

In the door pocket case 26 constructed as described above, the solidification of the injection portion 34 is slower than that of the other portions, and distortion tends to remain, so that the mechanical strength is low. Is unchanged. However, it is avoided to form a convex portion like the conventional one on the inner side surface portion of the portion, and conversely, a concave portion 35 is formed and the portion is depressed from the peripheral surface, so that it is stored in the door pocket case 26. There is no object that hits the injection part 34 part,
It is possible to prevent the impact due to the contact from being applied to the injection portion 34, and it is possible to prevent the occurrence of cracks and the like as in the conventional case.

Further, since the recess of the recess 35 is connected to the inner bottom surface of the door pocket case 26 without any step, it is possible to easily and without leaving the recess by wiping or the like, so that dust and dirt accumulate in the corners. It can be used cleanly. Further, since the convex portion 36 is formed on the outer side surface of the injection portion 34, the reinforcement of the injection portion 34 of the door pocket case 26 can be prevented without hitting the articles stored in the door pocket case 26. Thus, cracks and the like in the injection portion 34 can be more reliably prevented.

In addition, since the convex portion 36 is formed in a ring shape surrounding the injection portion 34, the reinforcement of the injection portion 34 of the door pocket case 26 enhances the quality of articles stored in the door pocket case 26. Not only is it possible to avoid hitting, but also in particular, it is economical to use fewer materials.

Further, in this case, although the door pocket case 26 is transparent as a whole, the injection portion 34 is apt to be whitened due to the distortion that is likely to remain, and a processing 38 of fine irregularities on the entire bottom is added to the door pocket case 26. The degree of whiteness increases. On the other hand, since the convex portion 36 has a ring shape and surrounds the injection portion 34, the ring-shaped convex portion 36 is particularly conspicuous from the inside so that the white color of the injection portion 34 is not conspicuous. It can improve the so-called appearance.

In the above-mentioned structure, since the convex portion 37 is also formed inside the convex portion 36 of the door pocket case 26, the reinforcement of the injection portion 34 of the door pocket case 26 is further enhanced. Although it can be surely provided, this may be provided as needed.

Also, door pockets 20 to 25 other than the door pocket case 26 are similar to the door pocket case 26,
Although the concave portions 35 and the convex portions 36 and 37 and the fine unevenness processing 38 are provided, these may be provided only in necessary ones.

In addition to the refrigerator compartment door 16, the door pocket is
The freezing room upper door 17, the freezing room lower door 18, and the vegetable room door 19 may be provided, or may be provided only in necessary ones. Further, as a whole, the present invention can be widely applied to storages other than refrigerators, for example, storages at normal temperature and storages at normal temperature.

[0021]

The door pocket case of the storage according to the present invention is as described above, and has the following effects. First, in a molded article made of a plastic material injected from a substantially central portion of a bottom portion, an article accommodated in a door pocket case 26 is injected by indenting an inner surface portion of the injection portion from a peripheral surface. It is possible to avoid giving an impact to the part, and it can be used without generating a crack or the like unlike the conventional one.

Secondly, since the dents are connected to the inner bottom surface without any step, the dents can be easily cleaned by wiping or the like without leaving them, so that dust and dirt do not accumulate in the corners. Can be used cleanly.

Third, by forming a convex portion on the outer side surface of the injection portion, the injection portion of the door pocket case can be reinforced without hitting articles stored in the door pocket case. In addition, cracks and the like at the injection portion can be more reliably prevented.

Fourth, since the convex portion is formed in a ring shape surrounding the injection portion, the reinforcement of the injection portion of the door pocket case can be prevented from hitting articles stored in the door pocket case. In addition, the material used can be reduced.
