[0009]

A container having a grip portion projected on a parting line substantially at the center of a substantially flat upper wall, and a spout provided at an end of the upper wall extending from the grip portion and including the parting line. A guard that surrounds the gripping portion and surrounds the spout and forms a flat upper support surface on which other containers can be stacked is locked and fixed near the gripping portion. Therefore, the liquid does not remain at the time of use, the breakage of the spout can be prevented, and another container can be stacked on the upper support surface of the protector. Furthermore, since it is locked and fixed near the gripping part on the parting line at the center of the upper wall, the structure of the locking corresponding part is formed and locked at a position where the thickness can be obtained in blow molding, so that the strength is excellent, Ensuring that the protector is locked to the container body.

[0010] flop Rotekuta includes an inner peripheral side wall surrounding the gripping portion, and a side wall that guards to surround sandwiching the spout, the peripheral side wall in contact with the shoulder of the container body, this <br/> having an upper support surface Thereby, the protector can be fixed with a protector integrally formed.

Further, by locking and fixing the locking portions provided on the protector to the locking corresponding portions formed on the both legs supporting the gripping portion, the both legs which can form a structurally strong structure can be formed. The protector can be locked and fixed to the container body, so that the protector is securely locked to the container body.

The locking portion provided on the protector includes a groove formed in an inner peripheral side wall of the protector, into which both legs for supporting the grip portion are inserted, and a through hole formed in the groove. By locking and fixing the holes to the protruding locking corresponding portions formed on both legs, the groove serves as a guide path at the time of locking, and there is no play after being locked, Ensuring that the protector is locked to the container body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings.
The present invention is not limited to the following examples. 1 and 2 are perspective views of a liquid container in a state where a container body 1 and a protector 11 are separated, FIG. 3 is a perspective view showing an inner surface of the protector 11, and FIG. 4 is a view of a container in which a parting line is located on a diagonal line. It is a top view of an example.

The container body 1 of the liquid container shown in FIGS.
Is, for example, blow molded from high density polyethylene,
The grip portion 3 is provided so as to protrude on a parting line substantially at the center of the substantially flat upper wall 2, and a spout (injection port) is provided at an end of the upper wall 2 on the extension of the grip portion 3 that includes the parting line. 7) is also provided. A cap is attached to the outlet 7 by means such as screwing (not shown). The protector 11 is formed, for example, by injection molding of high-density polyethylene, and has an inner peripheral side wall 12 surrounding the grip portion 3, a side wall 13 guarding so as to sandwich the spout 7, and the container body 1.
Has an outer peripheral side wall 14 in contact with the shoulder portion 8 and a flat upper support surface 15 on which another container can be stacked.

On the upper support surface 15 of the protector 11,
In FIG. 1, four convex portions 16 are formed, and in FIG. 2, two convex portions 16 are formed. At the top of the convex portions 16, water-permeable holes 17 are provided. On the other hand, concave portions are formed on the bottom surface of the container body 1 at positions corresponding to these convex portions 16 (not shown), and when stacked, the convex portions 16 and the concave portions on the bottom surface of the container main body are fitted and proper. It is designed to be able to be stacked in a certain position. In addition, when the container is stored upside down, such as after use, drainage is possible through the water-permeable holes 17 formed in the upper support surface 15, so that rainwater or the like does not accumulate on the back side of the upper support surface 15.

The outer peripheral side wall 14 of the protector 11 is provided with a recess (or may be a through hole) 14a for handling, so that it can be transported using both hands, and transport is easy. Notches 12c and 14c are formed in the lower edge of the inner peripheral side wall 12 and the outer peripheral side wall 14 of the protector 11, whereby a non-contact is formed between the lower edge of the inner peripheral side wall 12 and the outer peripheral side wall 14 and the upper surface of the container body. An abutting portion is formed to prevent water and dust from collecting between the container body and the protector, and to enable washing with running water.

It is preferable to provide a plurality of reinforcing ribs 18 on the inner surface of the protector 11, as shown in FIG.
This has sufficient strength to withstand stacking of containers.

The locking between the container body 1 and the protector 11 is performed as follows. In the container shown in FIG. 1, the inner peripheral side wall 1 of the protector serves as a locking portion of the protector 11.
2, a groove 21 into which both legs 4 supporting the grip 3 of the container body 1 are inserted, and a through hole 22 in the groove 21. On the other hand, on both legs 4 of the gripping portion 3, a projection-shaped locking corresponding portion 5 is formed facing outward, and the through hole 22 in the groove 21 is locked with the projection-shaped locking corresponding portion 5. And fix it. The groove 21 serves as a guide path at the time of locking, and rattling after locking is eliminated.

In the container shown in FIG. 2, notch fitting portions 25, 26 formed on a flat plate portion 24 connected to the inner peripheral side wall 12 of the protector 11 as locking portions of the protector 11.
Are respectively fitted and locked to projection-shaped locking corresponding portions 5a and 5b formed on both legs 4 supporting the gripping portion 3 of the container body 1. By forming the locking position at the parting line position on the upper surface of the container main body where the thickness can be obtained in blow molding, the strength of the locking portion is improved, and the protector is securely locked to the container main body.

FIG. 4 shows a container in which the parting line is located on a diagonal line, and the spout 7 is located at a corner of the container body 1. As a locking portion of the protector 11, a notch fitting portion 25 formed in a flat plate portion 24 continuously provided on the inner peripheral side wall 12 of the protector 11 is attached to both sides of both legs 4 supporting the holding portion 3 of the container body 1. Is fitted and locked to the projection-shaped locking corresponding portion 5c. Reference numeral 15 denotes an upper support surface of the protector 11.

[0022]

According to the liquid container of the present invention, the liquid does not remain at the time of use, the spout can be prevented from being damaged, and other containers are stacked on the upper support surface of the protector. it can. Furthermore, since it is locked and fixed near the gripping part on the parting line in the center of the upper wall, it is locked at a position where the thickness can be obtained in blow molding,
Ensuring that the protector is locked to the container body.
