Description

[Detailed description of the invention] (Technical field of the invention) This invention relates to a container for storing liquids, etc., and particularly to a relatively large-capacity, portable container for storing liquids, etc., made of a directly blown container body. It is.

(Prior Art) Conventionally, containers for storing relatively large volumes of liquids have been molded by direct blowing using synthetic resin materials such as polyethylene, polypropylene, and vinyl chloride. In general, the injection and spout ports and air vents are protruded from both ends of the top surface of the container body, and a handle is provided at the center of the top surface for transportation, and a handle is provided at the top of both ends of the body for transportation. It also has a recess for holding it. However, in the case of levers, due to restrictions in direct blow molding, each corner and ridge of the container body is unavoidably given a roundness corresponding to the overall size. Although it is preferable because the inner surfaces of corners and ridges can be effectively cleaned, it has the disadvantage that the strength of these parts, which are likely to collide with other objects during transportation and movement, is reduced, and the external shape has not been changed recently. Not only does it have the disadvantage that it cannot be made into a square shape, which tends to be a cubic type, but on the other hand, the injection, pouring or air openings protruding from both ends of the top surface become an obstacle to stacking the container bodies themselves. It is inconvenient to store and organize, and furthermore, since the capacity is relatively large, the weight increases when the inside is filled with liquid, etc., so that it can withstand the weight of the handle provided at the center of the top surface. This caused problems such as difficulties in the support structure.

[Summary of the idea]

In order to improve these conventional drawbacks, this invention was developed by exposing the injection and spout ports on the upper surface of the container body, as well as the air port if necessary, to the upper part of the container body for containers that are directly blow molded. , and with the handle part on the top surface covered by the covering part, a cover cup positioned higher than these is attached, and the attached cover cup is relatively attached to the center part of the upper surface during molding. The handle is supported in a freely undulating manner by using the thickly formed and left protruding parts, so-called burrs, and the base cup is also attached to the lower part of the container body as necessary, and each corner and ridge corner is This makes it possible to reinforce the parts and stack the containers on top of each other, as well as to sufficiently withstand the weight burden, and to obtain a structure that satisfies the preference for a rectangular appearance.

〔Example〕

Hereinafter, one embodiment of the container for storing liquids and the like according to this invention will be described in detail with reference to FIGS. 1 to 5.

1 and 2 show a longitudinal section and a plane of the container of this embodiment, and in each of these figures, the container main body 1 has recesses 3 for handling,
3 and a rectangular cross section, an upper protruding edge 4 and a lower protruding edge 5 that are around the upper and lower edges of the intermediate torso 2, and It consists of an upper body part 6 having an inlet 8 and an outlet 9, one of which also serves as a vent, at both ends of the upper surface 7, and a lower body part 10 having a lower surface 11 below the lower protruding edge 5, These are completely molded by direct blowing using synthetic resin materials such as polyethylene, polypropylene, and vinyl chloride, with each corner and ridge having a large roundness. A support portion 12 as a relatively thick protrusion (so-called burr portion) is permanently formed on the upper surface 7 as shown in FIG. Here, as seen in the protrusion 14 of the lower surface 11, this support part 12 is normally cut out as an unnecessary molded part, but in this invention, as will be described later, the handle is In order to utilize it as a support part for the support part, it is cut into a shape leaving a protrusion range suitable for the support part, and a receiving hole 13 is bored in it.

Further, the upper body part 6 is opened at each part of the inlet 8 and the spout 9 so as to avoid these parts, and the upper surface 7 is opened so as to cover the part of the protruding part 12.
A cover cup 15 made of the same material and made of the same material is fitted from above.

As is clear from FIGS. 3 and 4, this cover cup 15 corresponds to parts of both end sides excluding the pouring space and parts corresponding to both sides, that is, at least to the peripheral wall of the middle body part. In the part where
A pair of upright wall portions 16 occupying the upper surface of the upper body portion 6 and facing each other and located higher than the inlet 8, the spout 9, and the carrying handle in the collapsed state, which will be described later. 16 and each rising wall part 1
It has a covering part 17 located between 6 and 16 and covering the part of the support part 12, and is formed into as rectangular shape as possible. It is fixed to the outer circumferential surface by an undercut 18, that is, by mutual engagement of the uneven surfaces formed in each part, and is tightened by locking nuts 19, 20 at the exposed bases of the inlet 8 and the outlet 9. Furthermore, each rising wall portion 16, 16
and the receiving hole 13 of the support part 12 through the covering part 17.
The support rod 21 is pierced through the support rod 21, and by these means, the cover cup 15 is attached to the upper trunk 6.
It is integrally connected to sufficiently withstand the weight burden when suspended.

Further, the support rod 21 includes each rising wall portion 16,
A handle 22 for suspending the container itself is pivotably supported across the gaps between the container 16 and the covering portion 17, and both outer surfaces of the respective rising wall portions 16, 16 are attached to both ends of the support rod 21. End caps 23, 23 are applied to each of the inlets 8 and 9, respectively, and inner caps 24, 25 which also serve as packing are attached to the inlet 8 and outlet 9.
The opening/closing lids 26 and 27 are screwed in such a way that they can be opened and closed freely.

As for the lower body part 10, a base cup 28 made of the same effective material is formed into as rectangular shape as possible so as to correspond to at least the circumferential wall of the middle body part.
is fitted into contact with the lower surface 11 from below.

This base cup 28 is connected to the cover cup 1.
The pedestal part 29 has an outer dimension slightly smaller than the inner dimension between each rising wall part 16, 16 in 5.
, and unlike the cover cup 15,
Since there is no weight burden when it is hung, its integral connection to the lower trunk 10 is simply by anchoring the inner circumferential surface of the upper edge to the outer circumferential surface immediately below the lower protruding edge 5 using the undercut 30. However, in order to reliably prevent it from falling off during transportation, as shown in FIG. ,
This bolt 31 is attached to the pedestal portion 29 of the base cup 28.
It is preferable that the pedestal part 29 be made to protrude downward through it and be fastened with a locking nut 32 in a hollowed out part of the pedestal part 29, and that the pedestal part 29 is preferably provided with a drain hole 33.

Therefore, in the case of the configuration of the above embodiment, the container itself can be suspended with the handle in an upright position,
In this state, the handle configuration can sufficiently withstand the weight burden, and when the handle is laid down, the handle is housed between each rising wall, so that a series of displacements of the container itself occur. It is possible to stack upright or stacked in a cross-shaped structure without any problems.Furthermore, the cover cups and base cups are fitted and fixed, so weak corners are reinforced, and the overall structure is improved by these fittings. The shape can be made into a cubic type.

In the above embodiment, an inlet, a spout, or an air vent is provided at both ends of the upper surface of the upper body, if necessary, but these may be provided at least on one of both ends of the upper surface. good. In addition, the base cup may be omitted mainly due to cost considerations; in this case, the rounded part of the lower body is shaped so that it can fit between each rising wall, making it possible to perform stable stacking. However, it is effective to make the shape of the lower trunk portion as square as possible, and to give the lower surface corresponding to the pedestal a shape that can fit between similar rising wall portions. Furthermore, it goes without saying that the attachment of the cover cup and base cup to the container body is not particularly limited to the embodiments and may be arbitrary.

[Effect of idea]

As detailed above, according to this invention, the upper body has an inlet, an outlet, or an air inlet as necessary on at least one of both ends of the upper surface, and a support part in the center, a middle body and In a container whose main body is formed by direct blowing, the upper body has an inlet, an outlet, etc. exposed to the outside, and a supporting part is covered with a covering part. a cover cup having a rising wall portion having a shape corresponding to at least the peripheral wall of the middle body portion is fitted and fixed so that the cover cup is positioned as high as possible;
The handle is pivoted to the support rod that passes through each rising wall, covering, and support, allowing it to move up and down.
The cover cup can be securely connected to the container body, and the weak corners of the main body can be reinforced, and the inlet, spout, and supporting parts on the top surface do not need to protrude. It is possible to easily obtain a handle structure that can withstand the above, and the protrusion left during blow molding can be effectively used for the support part. In addition, a similar rectangular base cup may be fitted and fixed on the lower body as necessary, and the inner surface dimensions between each rising wall of the upper body may be attached to the lower surface of this base cup or the lower surface of the lower body. Since the pedestal part has an external dimension slightly smaller than that of the pedestal, it is possible to stack the containers upright in a series without shifting, or to stack them in a grid pattern, while also improving the overall appearance. It has the feature that the shape can be made into a cubic type that matches the rectangular orientation.
