Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a container used for storing, storing, and transporting a large number of articles.

[Conventional technology]

2. Description of the Related Art Conventional containers used for storing, storing, and transporting articles are increasingly being molded from synthetic resins because of their advantages such as ease of molding and light weight.

In this type of container, a lattice-like partition wall is installed inside the container according to the size of the items to prevent the items stored therein from colliding with each other and being damaged during transportation. However, this configuration not only increases the weight but also has the major disadvantages of being difficult to clean. A recess is formed to match the shape of the article, and the article is fitted and held in the recess. A through hole is formed at the bottom of the recess so that washing water can be drained through the through hole.

In addition, in order to facilitate the storage of a large number of containers when not in use, the containers can be rotated 180 degrees relative to each other and placed in a stacked position, thereby reducing the overall volume. , those with a configuration that can be returned to 180 degrees and placed in a stacking position when in use, for example, JP-A-52
There is a structure shown in the -24784 publication.

Furthermore, since this type of container requires a large amount of synthetic resin, which has a high raw material unit price, to mold one product, it is necessary to minimize the amount of synthetic resin material required to mold one container. In addition, lightening is performed within the allowable range of mechanical strength, for example, as disclosed in Japanese Patent Laid-Open No. 49-37778.

[The problem that the idea attempts to solve]

The container shown in Japanese Patent Application Laid-open No. 52-24784 has the advantage of making the container convenient for practical use.
Since the entire container has a configuration in which the width narrows downward, when containers are mated together and stacked, the upper container will fit into the lower container more firmly than necessary, resulting in a problem with the mating. There was a problem in that it took time and effort to separate containers stacked together. In addition, since recesses and protrusions are formed on the side walls of the container to enable containers to be stacked together and stacked together, the space inside the container cannot be effectively used for storing goods. There is the disadvantage that a large dead space is created inside the container, and furthermore, since the concave portions and convex portions are provided at specified locations, especially when the containers are stacked, the support points for the upper containers by the lower containers are limited. For this reason, there was a problem in that a load was applied locally to the lower container, resulting in improper deformation of the container.

Furthermore, the window hole for thinning in the container shown in JP-A No. 49-37778 is merely for thinning out, and although it is possible to obtain the effect of reducing the amount of synthetic resin material, This has the disadvantage of unnecessarily complicating the molding operation and the construction of the molding apparatus, which offsets the effect of reducing the amount of synthetic resin material obtained.
Furthermore, the container disclosed in this Japanese Patent Application Laid-open No. 49-37778 is also capable of switching the containers between the mating and stacking posture and the loading and stacking posture; Similar to the containers shown in the above publication, there were problems such as difficulty in handling the containers in a fitted and stacked state, and deformation due to uneven support locations.

Furthermore, the container shown in Publication of Utility Model Publication No. 38-21188 has a structure in which a hole for draining water is simply formed at the bottom of the recess, so it is simply said that drainage is better when cleaning the container alone. However, there was a problem in that it was not possible to drain the water while the items were stored.

Therefore, the present invention was devised to solve the above-mentioned problems of the conventional technology, and it is possible to store and hold articles while maintaining them in a constant posture, and also to easily clean the container. It is possible to effectively drain water inside the container while it is stored, and it is also possible to easily and smoothly switch between mating and stacking containers together, and the load of the upper container is localized to the lower container. The purpose is to prevent this from happening.

Another object is to make the side wall of the container itself strong against rolling loads, and to enable the interior space of the container to function advantageously for storing articles.

[Means to solve the problem]

The means of the present invention to achieve the above object are as follows: The basic structure of the container, which is a box, is a rectangular cylinder with a bottom. a lip flange located therein, a loading flange located below the lip flange, and a die-cut tapered surface whose upper end is sloped outward by bulging outward over the entire height of the side wall; forming recesses that become narrower as they move downward; forming the recesses at regular intervals along the circumferential direction of the side wall and having vertical inner edges; and forming the recesses between the recesses. A loading step is formed at the upper end of the side wall portion where the window hole is formed, and a point is formed between the loading step and the leg which is the lower end of the recess. symmetrically arranged, recessed placement parts arranged at predetermined equal intervals on the bottom wall, holes provided at the bottom of the recessed placement parts, and an upper surface of the recessed placement parts from the top surface of the bottom wall to the through holes. to form a groove in;

[Effect]

Since the articles to be stored are stored in the container with their bottoms fitted into the recessed placement parts, they are stored and held in an orderly manner without colliding with each other.

In addition, when items are stored neatly in a container without any gaps, the inner surface of the container that the items come into contact with, that is, the inner surface of the side wall, is perpendicular to the bottom surface, so the stored items will extend over the entire height range of the side wall. This will make contact with the inner surface of the container, thereby ensuring that the product remains upright safely within the container.
Stable storage and retention of articles is achieved.

Since the inner surface of the container is composed of a combination of vertically flat surfaces, it is easy to clean, and during this cleaning, the cleaning water can be quickly drained through a large number of windows and through holes. This allows the washing water to drain better. Additionally, if water is generated inside the container due to condensation on the surface of the product or melting of ice used to cool the product during transportation and storage, this water will quickly form on the top surface of the bottom wall due to its own weight. Since water is drained from the groove through the through hole, it is possible to completely eliminate the inconvenience of items inside the container being soaked with water.

The side wall is formed with a number of recesses having tapered surfaces, and window holes are formed in the side wall portions where the recesses are not formed by removing these side wall portions, making it easy to synthesize the container. This means that when integrally molded with resin, removal from the mold can be achieved extremely well.

Now, if we stack up containers in the same orientation, the upper and lower containers will fit together with the recess of the upper container intruding into the recess of the lower container, and the mouth flange of the lower container will fit. The insertion limit is regulated at the position where the loading flange of the upper container is loaded onto the upper end surface formed by the container. Therefore, when containers are stacked together in a fitted manner, a higher-ranking container does not fit into a lower-order container more than necessary, and the containers stacked in a fitted manner can be smoothly separated from each other.

When the containers are rotated 180 degrees, the loading stages and legs are arranged symmetrically with respect to the center of the container, so the loading stages and legs of the upper and lower containers will be positioned vertically opposite each other. . Therefore, when containers are stacked in this state, the lower end of the upper container fits into the opening of the lower container, and the legs of the upper container are loaded onto the loading step of the lower container. becomes.

As is clear from these two stacking positions, the lower container part on which the upper container is stacked is a loading step formed at the upper end of the vertical side wall part that forms the window hole, so the rolling down load in the stacked state is This support is achieved by the vertical side wall sections, which provide a high mechanical strength against the applied loads. Further, since a large number of the stacking steps are formed at regular intervals along the side wall, the load acting on the side wall is applied almost uniformly over the entire circumference of the side wall.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

The container 1 basically has a structure in which a side wall 2 in the shape of a right-angled rectangular straight cylinder and a bottom wall 15 in the shape of a right-angled flat plate are integrally molded from synthetic resin.

The upper end surface 4 of the container 1 is attached to the upper end of the outer peripheral surface of the side wall 2.
A lip flange 3 forming a flange 3 is integrally provided around the rim, and a loading flange 5 is provided below the rim flange 3 at a constant interval and circumferentially in parallel therewith.

The recess 6 formed in the side wall 2 is formed on the side wall 2 on the longitudinal side.
On the part, one short side (left side in Figure 1)
There are six of them, biased towards the other side (the first
Three pieces are provided on the short side (left side in the figure), and four pieces are provided on the other short side (right side in FIG.
becomes.

Each recess 6 has one end connected to the vertical part 10 and a pair of pillar plates 7 that protrude outward and face each other, and the other end of the pillar plates 7 connected to each other, with the upper end facing outward. It is composed of an inclined plate 8 having an inclined die-cutting taper surface, and this inclined plate 8 becomes narrower as it goes downward, and has a vertically elongated inverted trapezoidal shape when viewed from the front. Therefore, both pillar plates 7 are in an inclined position that widens upward relative to each other along the legs of this inverted trapezoidal shape.

The lower end of this recess 6 is connected to the bottom wall 1 by the width of both pillar plates 7.
The lower end of the recess 6 that protrudes outward from the periphery of the bottom wall 15 is
A part of the bottom wall 15 is extended to form a bottomed leg portion 9.

The vertical part 10 includes a bottom wall 15 from the loading flange 5.
A window hole 11 is formed by opening a portion extending to the lower end connected to the window hole 11, and a vertical plate portion 12 is formed above the window hole 11 for reinforcement. The loading stepped portion formed at the upper end of this vertical portion 10 includes a loading flat plate portion 13 formed over the entire width range, and an upright plate portion 14 located on the outside of this loading flat plate portion 13.
When the leg part 9 of the upper container 1 is in the loading position on the loading flat plate part 13, this leg part 9
The upright plate part 14 is in contact with the outer surface of the upper container 1, and the lower end of the upper container 1 assembled in a loaded and stacked state is fitted into the opening of the lower container 1. This prevents the container 1 from shifting in the lateral direction.

The bottom wall 15 is provided with two parallel rows of four recessed placement parts 16 each having a substantially elliptical shape in plan view, and a through hole 17 is formed in the bottom of each recessed placement part 16. However, this through hole 17 is inserted from the top surface of the bottom wall 15.
Since the grooves 18 are formed both vertically and horizontally, one through hole 17 has four grooves 18 formed therein. In this way, the through hole 17
By forming grooves 18 from all sides,
Water located on the bottom wall 15 can be quickly drained through the through hole 17.

A rib 19 is provided on the lower surface of the bottom wall 15, avoiding the through hole 17.
The bottom wall 15 is shaped by this rib 19.
The mechanical strength against loads is increased.

[Effect of idea]

Since the present invention has the above-described configuration, it exhibits the following effects.

Since the inner circumferential surface of the container that the stored articles come into contact with is a vertical plane, articles stored in an upright position on the bottom wall will come into contact with the inner circumferential surface of the side wall of the container over the entire height range of the side surface. As a result, the storage position of the articles within the container becomes extremely stable without wobbling. In addition, the article storage space inside the container, which has a basic shape of a straight, right-angled rectangular cylinder with a bottom, remains in its basic shape and has no unnecessary protruding parts, making the interior effective for storing articles. Can be done.

Since the degree to which the upper container fits into the lower container is regulated by the loading flange, it is possible to smoothly disassemble the fitted and assembled containers, thereby facilitating the smooth handling of a large number of containers. be able to.

Since the recesses are provided at regular intervals, the pair of opposing column plates in the recesses function as reinforcing ribs to reliably prevent a decrease in the mechanical strength of the side wall due to the provision of window holes. The container can be smoothly removed from the mold during container molding, and the legs are formed by extending the concave part that supports the load from above downward as it is, so the legs can be suitably formed. be able to.

Since a window hole is formed in the vertical surface part of the side wall, it is possible to eliminate the vertical wall part which is inconvenient for mold cutting, and also to effectively achieve the thinning, and also to effectively drain water when washing the container. Since the entire interior of the container is open upward, the interior of the container can be cleaned extremely easily.

Since the loading step is formed at the upper end of the vertical part of the side wall, the loads acting on the container are supported by this vertical part of the side wall and the recess, thus providing a high mechanical resistance to the applied loads. In addition, since a large number of loading steps and recesses are formed at equal intervals along the side wall, the load acts almost uniformly over the entire circumference of the side wall, which prevents uneven load. There is no risk of improper deformation of the side wall caused by the container, and since the legs are formed at the lower ends of the recesses that support the load, the container as a whole can achieve good and stable load support.

A groove is formed from the top surface of the bottom wall to the through hole, so even if items are stored, water that flows down onto the bottom wall will be quickly drained from this groove through the through hole, so that it will not be difficult to store items. It is possible to eliminate the inconvenience of items being soaked with water.
