DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle bottle with a handle, and more particularly, to the depth of a plurality of annular grooves provided on the peripheral surface of the bottle body below the handle. And a handle bottle which gradually becomes shallower toward the center of the anti-grip portion to disperse the deformation direction in the circumferential direction.

[0002]

2. Description of the Related Art A handle bottle is, literally, a plastic container in which a grip portion is integrally formed on a bottle body. For example, when carrying a large volume of liquid, the handle bottle is securely and securely held by the grip portion. In recent years, it has become commonplace for consumers to buy soy sauce and other seasonings used at home in bottles because of their portability.
The handle bottle has been reduced in weight in response to demands for cost reduction, resource saving, and environmental conservation, and as a result, the handle bottle has become thinner and various measures have been taken to avoid a decrease in strength. A conventional general handle bottle is shown in FIGS.
As shown in FIG. 3, a bottle body a including a bottom f, a body g, and a mouth h includes a gripping part b, and the strength of the peripheral surface of the body part g of the bottle body a below the gripping part b is increased. A plurality of annular grooves c are provided for raising, and the depth of the annular grooves c is formed to be constant. That is, the diameter d1 of the body g and the diameter d2 of the annular groove c form a concentric circle, and the difference (d1-
d2) is constant.

[0003] In this handle bottle, the grip portion b has a concave portion i.
As a result, the strength of the concave portion i and its peripheral portion is increased, and on the other hand, the trunk g1 immediately below the grip portion b
In addition, stress concentrates on the trunk g2 immediately below the anti-gripping portion b and the concave deformation occurs, and conversely, the two trunks g immediately below the recess i and the periphery thereof.
3 and g4 will be convexly deformed. Accordingly, in this handle bottle, as shown in FIG. 14, when the axial load of the empty bottle is applied, stress concentrates on the trunks g1 and g2 and the concave deformation occurs, and conversely, both trunks g3 and g4 deform convexly. do it,
Directionality occurs in the circumferential deformation of the torso g (becomes an elliptical shape as shown in FIG. 15), and in the worst case, buckling may occur. In order to avoid this, there is known a handle bottle in which the thickness of the body portion g1 or g2 is increased to increase the strength.

[0004]

The handle bottles shown in FIGS. 12 and 13 are light in weight and fulfill the demands of cost reduction, resource saving and environmental protection. The load is concentrated on the handle bottle, and the above-mentioned buckling phenomenon often occurs in the handle bottle in that portion. In addition, the thicker handle bottle increases the weight even if the buckling phenomenon can be avoided, and goes against demands for cost reduction, resource saving, and environmental conservation.

Accordingly, an object of the present invention is to provide a balance between concave deformation and convex deformation and to prevent buckling even when an axial load is applied when an empty bottle is applied, while ensuring light weight. To provide a handle bottle.

As shown in FIG. 7, when a load is applied to the mouth portion 2 in the direction of the arrow in the state of an empty bottle, the depth M of the annular groove portion 8a becomes one as shown in FIG. Since the shallow portions E and F are dispersed in four places and further changed to the center portions A and B and the portions C and D, the circumferential deformation of the center portions A and B is performed similarly to the embodiment of FIGS. As shown in FIG. 8, the directionality becomes outwardly convex (overall, it becomes an ellipse closer to a perfect circle than FIG. 4) and does not become a starting point of buckling. Further, the concave portion 6 of the grip portion 7 and its peripheral portion have originally high strength due to their shapes, and as a result, the strength of the axial load is improved.

Since the center portions A and B and the portions C and D are changed, similarly to the embodiment of FIGS. 1 to 4, the circumferential direction of deformation of the center portions A and B becomes outwardly convex (as a whole, FIG. It does not become the starting point of buckling (it becomes an ellipse closer to a perfect circle than 8). Further, the concave portion 6 of the grip portion 7 and its peripheral portion have originally high strength due to their shapes, and as a result, the strength of the axial load is improved. Even if the depth M of the upper and lower annular grooves 21 and 22 is reversed, the center A and the center B may be replaced by the depth M of the upper annular groove 21. Other configurations and operations are the same as those of the embodiment of FIGS.

EXAMPLES The usefulness of the handle bottle of the present invention will be described below with reference to examples. <Test Samples> Four types of bottles were used as samples of the present invention. As a comparative example, a bottle having a conventional shape (having a perfect circular cross section) was used. A shape: the shape of FIG. 5 B shape: the shape of FIG. 1 C shape: the shape of FIG. 9 D shape: the shape of claim 4 All the bottles were molded with a resin amount of 56 g. In addition, samples of 53 g and 59 g bottles were also used. The number of samples was 53 for 53 g of the conventional shape, but 5 samples were used for all other shapes.

<Measurement physical properties> The compressive strength (kgf) of the empty bottle and the displacement (mm) during buckling were measured. <Measurement method> Each sample bottle was buckled by applying an axial load.
At that time, the reduced dimension (displacement amount) in the vertical direction (vertical direction), the wall thickness at the buckling position, and the axial load strength were measured. Table 1 shows the measurement results. In addition, since the thickness of the buckling position of each sample is slightly different, in order to compare when the thickness is the same, the "displacement" and "strength" per unit thickness are set as follows. I asked. “Displacement”: displacement / (strength ÷ wall thickness) “Strength”: strength / (displacement × wall thickness) In the data of Table 1, “displacement / strength” means that the smaller the numerical value, the less buckling under load. The expression “strength / displacement” indicates that the greater the numerical value, the greater the strength. FIGS. 16 and 17 are graphs showing the relationship between “thickness and displacement during buckling” and “thickness and compressive strength of empty bottle” of the samples obtained in the examples.

[0023]

[Table 1]

Although the embodiment of the present invention has been described above, it will be understood that the specific configuration is not limited to this, and that changes may be appropriately made without departing from the gist of the present invention.

[0025]

As described in detail above, according to the present invention,
Even if an axial load is applied when the bottle is empty, since the depth of the annular groove gradually becomes shallower as it goes toward the center of the gripper and the center of the opposite gripper, the circumferential deformation direction of that portion The convexity is outward and does not become the starting point of buckling, and the concave portion of the grip portion and its peripheral portion have originally high strength because of their shapes, and as a result, the axial load intensity is improved. Therefore, while ensuring that the weight of the bottle body is light, strength, especially even when an axial load is applied when the bottle is empty, the concave deformation and the convex deformation are balanced and the strength of the axial load increases,
No buckling.
