Description

[Detailed Description of the Invention] This invention relates to a liquid transport container. Liquid carriers are used in various fields in agriculture or industry. For example, in the case of spraying pesticides, containers are needed to transport the pesticides prepared at one location with convenient water access to the site. Since tanker trucks cannot be used in mountainous areas or fields where crops are already growing, it is desirable to be able to transport them on unicycles, which are widely used by farmers.

Until now, there has been no liquid transport container with a special shape that can be stably placed on the platform of a unicycle. In addition, since a large amount of liquid must be transported at one time, it is desirable that the container itself be strong enough to withstand the weight of the container, and that the container be structured so that the liquid inside can be discharged while the container is placed on the carrier of a unicycle.

The transportation container of the present invention has been devised to meet these demands.

The present invention includes an upper wall and a lower wall that are substantially parallel to each other;
It is a large plastic hollow container having a hexahedral three-dimensional shape, comprising both side walls and a rear wall that are substantially orthogonal to the upper and lower walls, and a front wall that extends outwardly from the lower wall to the upper wall. A liquid discharge port is provided at approximately the center of the ridge line that protrudes forward where it intersects with the wall, and a liquid outlet is provided at the center of both side walls of the container, extending from the rear wall toward the ridge line, first extending parallel to the lower wall, and then connecting the upper wall and the front wall. The present invention relates to a liquid transport container characterized in that it is provided with reinforcing ribs extending outwardly and projecting approximately along the bisector of the intersection angle of the liquid transport container.

For this reason, the three-dimensional shape of the container of the present invention, especially the front wall that slopes outward from the bottom wall to the top wall, is shaped to fit onto the loading platform of a unicycle, allowing the container containing liquid to be stably loaded. can be placed. The ridgeline where the front wall and the top wall intersect is located at the uppermost front of the container when viewed from the side, and the liquid outlet is installed approximately in the center of this ridgeline, so the outlet is normally located near the top of the container. Even if the lid is removed in this state, the liquid will not flow out, but by lifting the handle of the unicycle and tilting the container, the liquid can be easily drained from the container for transfer, etc. Eventually, the container can be emptied by tilting the container until the front wall is horizontal.

Furthermore, a reinforcing rib in the middle of the side wall that first extends from the rear wall parallel to the bottom wall and then along approximately the bisector of the intersection angle of the top wall and the front wall is located at the outermost contour of the container in plan view. In accordance with this, the strength of the container itself is reinforced, and the parts prone to collision are thereby reinforced. In addition, this reinforcing rib will merge with the ridge line where the top wall and front wall intersect at the front, so when blow molding the container, by providing a parting line along the reinforcing rib, the reinforcing rib can be installed. It does not interfere with opening the mold.

Next, an embodiment of this invention will be described based on the drawings. FIG. 1 shows a liquid transport container 1 according to this invention. The liquid transport container 1 is a large hollow container obtained by blow molding plastic such as polyethylene resin, and has a substantially hexahedral three-dimensional shape. As is clear from FIG. 1, the upper wall surface 2 of the container 1 is located on a horizontal plane like the lower wall surface 3, so when the container is placed horizontally, the upper wall surface 2 also becomes horizontal, making it easier to stack the containers. It is possible. In addition, the rear wall surface 4 is the upper wall surface 2 and the lower wall surface 3.
The flat part 5 forms a right angle to the rear wall surface 4.
occupies at least the central part of the rear wall surface 4.
It is also possible to arrange the containers vertically with the side facing down.
It can be seen from FIG. 3 that the side walls 6, 6 of the container 1 are generally symmetrical and are approximately perpendicular to the upper wall 2 and the lower wall 3. Furthermore, the front wall surface 7 slopes upward as it faces forward, and by sloping its lower part 8 at an even steeper angle than its upper part 9, it is possible to stably load the load onto a handcart (not shown). .

Further, on both sides 6, 6 of the container 1, reinforcing ribs 14 are continuously provided between the upper wall surface 2 and the lower wall surface 3 or the front wall surface 7, and the cross-sectional shape of the reinforcing ribs is, for example, rectangular. (See Figure 3). Each reinforcing rib 14 is
For example, by positioning the molded product on the parting line of a blow mold (not shown) during blow molding of the container 1, the molded product can be easily pulled out from the mold, and the formation of the reinforcing ribs makes it easier to transport the molded product. It has enough strength to withstand the impact that occurs. When viewed from the side of the container, each reinforcing rib 14 extends substantially horizontally from the rear of the container to the center, and then gently rises toward the front to reach the front end of the container.

The front wall of the container 1 has a small opening 15 located at the center of the width of the container as shown in FIG. The inner diameter of the small opening 15 may be large enough to allow insertion of a normal hose, and the cap 16 can be screwed into the small opening in a fluid-tight manner. The position of the small opening 15 is preferably at an obtuse angle with respect to the front wall surface 7 when viewed from the side of the container as shown in FIG. Can be discharged. on the other hand,
The upper wall surface 2 of the container has a large opening 1 as shown in FIG.
7, and the large opening is preferably slightly rearward of the center in the longitudinal direction of the container. Large opening 17
The inner diameter of the cap 18 only has to be large enough to allow insertion of a normal ladle, and the cap 18 can be fitted into the large opening in a fluid-tight manner. As shown in FIG. 3, the upper end surface of the cap 18 is set to be located almost on the same plane as the upper wall surface 2 of the containers when they are fitted, so that the cap 18 does not become an obstacle when stacking the containers 1. Never. As is clear from FIGS. 4 and 5, the large opening 17 has an inner circumferential wall 19 whose diameter gradually decreases downward and forms an inward annular flange 20 at its lower end. The annular flange portion 20 has at least one
A pair of notches 21, 21 are provided in the diametrical direction. The cap 18 also has an outer circumferential wall 22 with a gradually decreasing diameter corresponding to the inner circumferential wall 19, and the annular flange portion 20 forms a cylindrical portion 33 having approximately the same diameter as the inner diameter at the lower end surface thereof. A notch 2 is provided on the outer side of the lower end of the cylindrical portion 23.
Projections 24 corresponding to 1 and 21 are formed. In the cap 18, it is preferable to attach an annular packing 25 to the lower end surface of the cap excluding the cylindrical portion 23, and this packing prevents liquid from leaking from the large opening 17 when the cap 18 is fitted.

To transport the containers 1 of this invention to users such as farmers, they are stacked or placed vertically in a truck or light van. During this stacking, loading, and unloading work, compressive stress, bending stress, etc. are generated in the container 1, but a reinforcing rib 14 is provided in the vertical center extending almost the entire length of both side wall surfaces 6 of the container. Therefore, the container 1 will not be dented or bent. The position of the reinforcing rib 14 in the container 1 is on the parting line of the blow mold for blow molding the container, so even if both reinforcing ribs 14 are formed on both side wall surfaces 6, 6, the molding of the container 1 will not be possible. The container, which is a molded product, can be easily cut out during processing.

As mentioned above, the liquid transport container according to this invention is very convenient especially when placed on a unicycle to transport liquids such as agricultural chemicals, but it is obvious that it can also be used for other purposes. .
