Description

Container with handle

The present invention relates to a container with a handle, and particularly to a large container with a handle made of a resin material and having a capacity of 10 liters or more.

Conventionally, large containers of about 5 gallons (about 20 liters) have been adopted all over the world as, for example, refillable bottles for mineral water. Such a large container is generally formed of a resin material, and is light in the empty state, so it is relatively easy to carry. However, in a state filled with mineral water, the container is quite heavy and difficult to carry. Further, for example, when placing a container on a water server, it is necessary to invert the opening so that the opening faces downward after lifting the container, which is very difficult to handle.

In order to facilitate the transportation and handling of such a large container, there is one provided with a handle extending along the axial direction (vertical direction) of the trunk part on the outer peripheral part of the container body (plastic bottle) (for example, Patent Document 1).

It is a rear view of the container with a handle concerning one embodiment of the present invention. It is a side view of the container with a handle concerning one embodiment of the present invention. It is a top view of the container with a handle concerning one embodiment of the present invention. It is a bottom view of the container with a handle concerning one embodiment of the present invention.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 5, a container 1 with a handle according to this embodiment is used as a refillable bottle for mineral water having a capacity of about 5 gallons (about 20 liters), for example. And the handle member 20.

The container body 10 is formed of polyethylene terephthalate (PET) resin, and connects the neck portion 12 having the opening 11 at the upper end, the cylindrical trunk portion 13, the neck portion 12 and the trunk portion 13 from the neck portion 12 side. The shoulder portion 14 has an inner diameter that gradually expands, a bottom portion 15 that seals one end of the body portion 13, and a heel portion 16 that connects the body portion 13 and the bottom portion 15. A recess 17 is formed at the boundary between the shoulder 14 and the body 13 by cutting away a portion of the container body 10 in the circumferential direction. As shown in FIG. 3, the recess 17 has a stepped structure that is convex toward the container central axis when the container 1 is viewed from the side. Specifically, the concave portion 17 includes a steeply inclined wall surface 18 that extends downward from the shoulder portion 14 and to which the handle member 20 is attached, and a gently inclined wall surface 19 that extends in the radial direction and is connected to the body portion 13. Consists of.

A handle member 20 is attached to a steeply inclined wall surface 18 that defines the concave portion 17. By arranging the handle member 20 in the concave portion 17 in this way, the handle member 20 can be disposed in the vicinity of the central axis of the container body 10. The steeply inclined wall surface 18 is inclined so as to face obliquely upward in a state where the container body 10 is placed with the neck portion 12 as an upper side. That is, the steeply inclined wall surface 18 is provided to be inclined at a predetermined angle θ1 with respect to the bottom surface of the container body 10 (see FIG. 3). Further, the steeply inclined wall surface 18 is a curved surface having a concave portion on the center side of the container body 10 (see FIG. 4). That is, the steeply inclined wall surface 18 has a curved structure in which the central portion has a curvature larger than the body portion 13 and protrudes radially outward of the container body 10 when the container 1 is viewed from above.

In addition, the length L1 of the shoulder 14 on the side where the handle member 20 is provided is 1/3 or more of the length L2 of the shoulder 14 where there is no recess 17 in consideration of the mounting stability on the water server. . Further, when the handle member 20 is provided below the intermediate height of the body portion 13, the operator needs to bend in order to grip the handle member 20. Therefore, the length in the vertical direction of the steeply inclined wall surface 18 to which the handle member 20 is assembled is set to 1/3 or less, more preferably 1/4 or less, of the total height of the body portion 13.

The handle member 20 includes an attachment portion 21 that is attached to the container body 10 and a handle portion 22 that is a portion that is actually gripped by an operator. The attachment portion 21 includes an attachment plate 23 provided along the steeply inclined wall surface 18. Although not shown, the attachment plate 23 is integrally provided with a pair of engaging portions that protrude from the container body 10 and are engaged with and held by the container body 10. That is, the engaging portion is provided on the attachment plate 23 so as to protrude in the container center direction on the opposite side of the vicinity of the joint portion with the handle portion 22 when the container 1 is viewed from above.

The grip portion 22 is provided to project in an arch shape on the surface (one surface) opposite to the container body 10 of the mounting plate 23. That is, both ends of the handle portion 22 are connected to the attachment plate 23 in a state where a predetermined gap is secured between the handle portion 22 and the attachment plate 23. In the present embodiment, the handle portion 22 is provided so as to protrude in a direction substantially orthogonal to the surface of the mounting plate 23. A gap region (through hole) between the handle portion 22 and the mounting plate 23 is formed in a horizontally long and substantially elliptical shape so that an operator's hand can easily enter. The handle portion 22 and the attachment portion 21 including the attachment plate 23 are formed by integral molding.

Moreover, since the weight of the container (5 gallon size) when filled with drinking water reaches about 20 kg at the maximum, a very large load is applied to the grip member 20 and the assembly part on the container side. For this reason, if the handle member 20 is easily deformed, the container body 10 may drop off from the engaging portion, or the handle portion 22 may be broken from the base of the mounting plate 23. Therefore, in the present invention, in order to increase the rigidity of the handle member 20, the first convex rib 22 a is provided on the outer peripheral surface of the handle portion 22, and the second convex rib 22 b is provided on the inner and outer surfaces near the base of the handle portion 22. Provided. In addition, the horizontal cross section of the mounting plate 23 has a curved surface shape with a central portion protruding toward the handle portion 22 side.

Such a handle member 20 is integrated with the container body 10 when the preform 10 is blow-molded to form the container body 10. That is, at the time of blow molding, an engaging part (not shown) constituting the attaching part 21 and the attaching plate 23 are engaged and held by the steeply inclined wall surface 18 of the container body 10, so that the handle member 20 is integrated with the container body 10. Is done. When the container body 10 is formed by blow molding, the attachment plate 23 has a curved shape as described above, so that the stretch ratio of the preform is substantially uniform at the center and both ends of the attachment plate 23. For this reason, compared with the case where the attachment plate 23 is a mere flat plate shape, the thickness of the part corresponding to the attachment part 21 of the container main body 10 is fully securable. Therefore, the handle member 20 can be firmly attached to the container body 10.

The molding method of the container body 10 is not particularly limited, but a suitable molding method is a two-blow method as disclosed in a prior application (Japanese Patent Laid-Open No. 2011-037139) by the present applicant. Can be mentioned. Specifically, first, a primary bottle having a concave portion having substantially the same size and shape as the concave portion 17 is formed by the primary blow mold, and then the handle member 20 is assembled to the concave portion in the secondary blow mold. It is a technique. If it does in this way, it will become possible to provide suitable thickness distribution over the whole container main body 10, and also heat resistance will improve compared with 1 blow system.

As described above, in the configuration of the present embodiment, since the attachment portion 21 of the handle member 20 includes the attachment plate 23, the container body of the handle member 20 can be provided even if the handle portion 22 is provided along the circumferential direction of the container body 10. A sufficient mounting strength for 10 can be secured. For example, when an operator grasps the handle portion 22 and lifts the container 1, the force applied to the attachment portion 21 is dispersed by the attachment plate 23, and the occurrence of a problem that the handle member 20 falls off the container body 10 is suppressed. Can do.

And the handleability of the container 1 can be improved by arranging the handle portion 22 along the circumferential direction of the container body 10. For example, it is particularly effective in a relatively large container used as a refillable bottle for mineral water.

In the present embodiment, the attachment portion 21 includes a pair of engagement portions that are integrally provided on the other surface (container body 10) side of the attachment plate 23 and are engaged and held by the container body. The attachment strength of the member 20 to the container body 10 can be further improved.

Furthermore, as described above, the steeply inclined wall surface 18 of the container body 10 is provided to be inclined at a predetermined angle θ1 with respect to the bottom surface of the container body 10 (see FIG. 3). The attachment plate 23 is formed along the surface of the steeply inclined wall surface 18, and the handle portion 22 is provided so as to protrude in a direction substantially orthogonal to the attachment plate 23. That is, the handle portion 22 is provided so as to protrude in a direction substantially orthogonal to the surface of the steeply inclined wall surface 18, and is provided to be inclined upward at a predetermined angle with respect to the bottom surface of the container body 10.

When the container 1 is lifted by the handle portion 22 when the container is full, a rotational moment is generated because the center of gravity of the container 1 is different from the fulcrum (the handle portion 22), and the container body 10 rotates with the handle portion 22 as a fulcrum. Inclined state. However, in the container 1 according to the present invention, the handle member 20 is disposed in the vicinity of the central axis of the container body 10 as described above. Is small. In addition, since the handle portion 22 is inclined upward at a predetermined angle, the angle between the straight line connecting the center of gravity and the fulcrum (the tip end side of the handle portion 22) and the vertical line is smaller than that in a simple horizontal state, The rotational moment is further reduced. Therefore, the container 1 can be stably held. In addition, when the container 1 in a full state is inverted to be placed on the water server, the present invention is easier to grip compared to the case where the handle member 20 is provided in the vertical direction of the trunk portion 13. The container 1 can be stably held. Thereby, the manageability of the container 1 further improves. Moreover, as shown by the phantom line in FIG. 3, it is desirable that the handle portion 22 is disposed within a region where the extension lines of the shoulder portion 14 and the trunk portion 13 intersect. With this configuration, even when the container 1 is inverted and installed in the water server, the handle member 20 does not contact the mounting table. Therefore, also when using the container 1 with a handle of the present invention, it is not necessary to change the water server, and it can be used in combination with a conventional water server.

Although one embodiment of the present invention has been described above, it is needless to say that the present invention can be variously modified without departing from the gist thereof.
