Description

  The present invention relates to a bottle.

  Conventionally, as in Patent Document 1, a cylindrical mouth portion, a cylindrical shoulder portion, a cylindrical trunk portion, and a bottomed cylindrical bottom portion are connected in this order from top to bottom along the bottle axis direction. Proposed bottles have been proposed. Moreover, as this kind of bottle, a small bottle having a small outer diameter of a body portion suitable for a small amount of contents is known as in Patent Document 2.

JP 2003-285814 A Japanese Patent No. 6259176

However, in the conventional small bottle, when the cap and the bottle are relatively rotated around the bottle axis and the cap is removed from the mouth portion, the outer diameter of the barrel portion is small, and thus the hand holding the barrel portion slips. It becomes easy. Therefore, even in such a small bottle, it has been required to improve the operability of the bottle.
In contrast, it is conceivable to provide a non-slip uneven portion on the body of the bottle, but if such an uneven portion is simply provided on the body of the bottle, when the label is wound around the outer peripheral surface of the body When the label is in line contact or point contact with the concavo-convex portion, the label is easily damaged.

  The present invention has been made in view of the above-described problems, and when the cap and the bottle are relatively rotated around the bottle axis, the hand gripping the barrel is not slippery and is attached to the outer peripheral surface of the barrel. An object of the present invention is to provide a bottle capable of suppressing the breakage of a broken label.

  The present invention employs the following means in order to solve the above problems. That is, the bottle of the present invention is a bottle in which a cylindrical mouth portion, a cylindrical shoulder portion, and a bottomed cylindrical body portion are continuously arranged in this order from the upper side to the lower side along the bottle axial direction. The cap can be attached to the mouth by being rotated with respect to the mouth around the bottle axis, the body is spaced apart in the vertical direction, and a label is attached to the outer peripheral surface. A pair of large-diameter portions that are possible, and a reduced-diameter portion that is disposed between the large-diameter portions and has a smaller diameter than the large-diameter portion, and the reduced-diameter portion is directed radially outward. At least one projecting portion projecting in a radial direction, and a radial distance between a radially outer end portion of the projecting portion and the bottle shaft is equal to or less than a radius of an outer peripheral surface of the large diameter portion, The outer diameter of the large diameter portion is larger than the outer diameter of the mouth portion and 1.8 times the outer diameter of the mouth portion It characterized in that it is a fully.

  In this invention, in the small bottle whose outer diameter of the body portion is smaller than the outer diameter of the mouth portion and less than 1.8 times the outer diameter of the mouth portion, When the cap and the bottle are relatively rotated around the bottle axis, the hand gripping the body portion is prevented from slipping, and the protruding portions are provided above and below the reduced diameter portion. Since the pair of large diameter portions does not protrude outward in the radial direction, the label attached to the body portion is less likely to be damaged.

In the present invention, the internal volume may be not less than 30 ml and not more than 150 ml.
In this invention, since the inner volume is a small bottle for 150 ml or less, preferably 100 ml or less, the outer diameter of the body portion is easy to be designed. However, as described above, when removing the cap from the bottle, Slip of the hand holding the part is suppressed, and the label attached to the body part is less likely to be damaged.

Further, in the present invention, a radial distance between the outer end portion in the radial direction of the protruding portion and the bottle shaft may be less than a radius of the outer peripheral surface of the large diameter portion.
In this invention, since the protruding portion is positioned radially inward than the pair of large diameter portions provided above and below the reduced diameter portion, it is possible to more reliably prevent the label attached to the body portion from being damaged. .

  According to the bottle concerning this invention, when removing a cap from a small bottle, it is suppressed that the hand holding a trunk | drum slips, and it becomes difficult to produce a damage to the label attached to the trunk | drum.

The outer diameter D3 of the lower end of the shoulder 4 is, for example, 34 mm.

  The body portion 5 is connected to the lower end of the shoulder portion 4 and is connected to the cylindrical first large diameter portion (large diameter portion) 11 extending in the vertical direction and the lower end of the first large diameter portion 11 and extends in the vertical direction. A cylindrical reduced diameter portion 12 is provided, and a cylindrical second large diameter portion (large diameter portion) 13 that is continuous with the lower end of the reduced diameter portion 12 and extends downward. The first large diameter portion 11, the reduced diameter portion 12 and the second large diameter portion 13 are disposed coaxially with the bottle axis O.

  The outer diameter D4 of the first large diameter portion 11 is, for example, 34 mm, which is larger than the neck ring 2B, and is constant in the vertical direction. In addition, a first reinforcing groove 15 that is recessed toward the inside in the radial direction is formed over the entire circumference at a connection portion between the first large diameter portion 11 and the reduced diameter portion 12. The first reinforcing groove 15 has a semicircular shape in the vertical cross section. In addition, the depth of the 1st reinforcement groove part 15 is 2 mm, for example, and the length of the up-down direction of the 1st reinforcement groove part 15 is 3 mm, for example.

  The reduced diameter portion 12 is smaller in diameter than the first and second large diameter portions 11 and 13. The reduced diameter portion 12 is provided with a plurality (18 in FIG. 1) of protruding portions 16 extending in the vertical direction in the circumferential direction. These protrusions 16 are protrusions having a semicircular shape in cross section, and are arranged in parallel to each other. Outer diameter (twice the radial distance between the outer end portion of the protruding portion 16 and the bottle shaft O) D5 of the reduced diameter portion 12 at the top of the protruding portion 16 is the outer diameter D4 of the first large diameter portion 11. It is the same. The outer diameter D5 may be less than the outer diameter D4. The length of the reduced diameter portion 12 in the vertical direction is longer than the length of the first large diameter portion 11 in the vertical direction, and is, for example, twice or more.

The outer diameter D6 of the second large-diameter portion 13 is equal to the outer diameter D4 of the first large-diameter portion 11, for example, 34 mm, and is constant in the vertical direction. In addition, a second reinforcing groove portion 17 that is recessed toward the inside in the radial direction is formed over the entire circumference at the connection portion between the second large diameter portion 13 and the reduced diameter portion 12. Similar to the first reinforcement groove 15, the second reinforcement groove 17 has a semicircular shape in the vertical cross section. Similar to the first reinforcing groove 15, the depth of the second reinforcing groove 17 is 2 mm, for example, and the vertical length of the second reinforcing groove 17 is 3 mm, for example.
The length of the second large diameter portion 13 in the vertical direction is equal to the length of the first large diameter portion 11 in the vertical direction. A label (not shown) can be wound around the outer peripheral surfaces of the first and second large diameter portions 11 and 13.

The bottom portion 6 is connected to the lower end of the second large diameter portion 13 and closes the lower end opening of the second large diameter portion 13. In addition, the length L2 of the up-down direction of the neck part 3, the shoulder part 4, the trunk | drum 5, and the bottom part 6 is 73.5 mm, for example. Further, L2 is preferably 3 times or more of L1. The bottle 1 is formed by blow molding a preform (not shown) formed by injection molding.

Next, a method of using the bottle 1 having the above configuration will be described.
A label (not shown) is wound around the bottle 1 from the first large diameter portion 11 to the second large diameter portion 13. First, the cap attached to the bottle 1 is removed. When removing, the cap is held with one hand, and the body 5 of the bottle 1 is held with the other hand. Then, the cap is rotated around the bottle axis O with respect to the bottle 1 in the direction of removing the cap. At this time, since the protruding portion 16 extends in the vertical direction intersecting with the removal direction with respect to the bottle 1, when the cap is rotated with respect to the bottle 1 in the removal direction, the body portion 5 of the bottle 1. The hand holding the finger and its finger are caught in the circumferential direction with respect to the protrusion 16. Therefore, it is difficult for the hand holding the bottle 1 to slide with respect to the trunk portion 5.
In this way, the cap is removed from the bottle 1. Thereafter, the contents stored in the bottle 1 are taken out as appropriate.
As described above, the bottle 1 is used.

  According to the bottle 1 configured as described above, it is possible to prevent the hand holding the body portion 5 from slipping when the cap is removed from the bottle 1, and at the time of transportation or display, when the cap is removed, and when the cap is attached. In such a case, the label wound around the body 5 is less likely to be damaged. Here, since the protruding portion 16 is formed as a semi-circular protruding ridge extending in the vertical direction, for example, the label is damaged as compared with a case where the protruding portion has a corner. Furthermore, it can prevent reliably.
