  An object of the present invention is to provide a novel bottle-type container that contributes to improvement in ease of gripping and ease of holding in a bottle-type container.

  In order to solve this problem, the first invention provides a bottle-type container having a container body portion, a grip portion, and a recess. The grip part is integrally formed with the container body part by sinking a pair of parts facing each other in the circumferential direction of the container body part. The concave portion is provided in a portion of the grip portion that is gripped by the thumb and the index finger or the middle finger.

  Here, in the first invention, the concave portion may extend in the circumferential direction of the grip portion. Further, the surface of the grip portion may be raised in a slope shape downward along the shape of the palm.

  The second invention provides a bottle-type container having a container body, a cylindrical neck, and a flange. The neck part is connected to the container body part with the upper part of the container body part narrowed as a root, and the top part is open. The flange portion protrudes laterally from the side surface of the neck portion on the way from the base to the top portion. Here, the interval between the base and the flange portion has an interval at which the neck portion can be gripped by the thumb and the index finger. Further, the lower surface of the flange portion is smoothly connected to the side surface of the neck portion in a curved shape.

  According to the first invention, when the bottle-shaped container is carried by gripping the grip portion, the thumb and the index finger or the middle finger fit into the concave portion provided on the surface of the grip portion so that the bottle-shaped container can be easily gripped. Even if the capacity is increased or the capacity is increased, there is an effect that it is easy to hold.

  Further, according to the second invention, when the bottle-shaped container is lifted by grasping the neck, the thumb and index finger are easily fitted to the curved surface connecting the flange and the neck, so that the bottle-shaped container has a large capacity and a large size. Even if it is changed, there is an effect that it is easy to lift.

  1 and 2 are side views of the bottle-type container according to the present embodiment. This bottle-type container 1 is a type called a pinch grip type in which a grip is integrally formed with the container. In this embodiment, a relatively large capacity (2.7 liter, 4 liter, etc.) into which beverages, alcoholic beverages, soy sauce, etc. are placed. ) Is assumed. As is well known, the bottle-type container 1 can be integrally formed by biaxial stretch blow molding using a thermoplastic synthetic resin such as polyethylene terephthalate, polybutylene terephthalate, and polyethylene naphthalate. The bottle-type container 1 is mainly composed of a container body portion 2, a grip portion 3, and a neck portion 4.

  The upper part of the hollow container body 2 is gradually reduced in diameter toward the upper side, and the neck 4 is provided on the top. A plurality of ribs are provided as appropriate on the surface of the container body 2 to ensure the strength of the container, and a pair of depressions 2a are also provided. These depressed portions 2 a are formed by sinking a pair of portions facing each other in the circumferential direction of the container body portion 2. The shape of these depressions 2a may be bilaterally symmetric or bilaterally asymmetric. In addition, the depressed portion 2a can be formed by subsequent depression after blow molding, but normally, by using a mold having a protrusion corresponding in shape to the depressed portion 2a, at the time of blow molding It is formed at the same time (this is the same for the other parts 3 to 5). And the outer peripheral surface of the container trunk | drum 2 from one depression part 2a to the other depression part 2a is equivalent to the grip part 3. FIG. As shown in the cross-sections of FIGS. 3 and 4, the grip portion 3 formed integrally with the container body 2 has a substantially Ω-shaped cross section and extends above and below the container body 2 with substantially the same grip width. Exist. The bottle-type container 1 is carried by holding the grip portion 3 with a hand.

  The grip portion 3 is provided with a recess 3a in order to enhance the fit when grasped. The concave portion 3a is provided at a portion of the grip portion 3 that is gripped by the thumb and the index finger (or middle finger), and is formed by recessing the surface of the grip portion 3 into a concave shape. Two specific shapes of the recess 3a are illustrated below.

  FIG. 3 is an XX sectional view showing an example of the recess 3a. The recess 3 a is provided along the curved outer surface of the grip portion 3 and extends over the entire circumferential direction of the grip portion 3. The groove shape and width of the recess 3a are appropriately set in consideration of the fit of the thumb and index finger (or middle finger). In the example shown in the figure, since the concave portion 3a extends in a substantially C shape in the circumferential direction of the grip portion 3, the thumb and index finger (or middle finger) are entirely in contact with the concave portion 3a.

  FIG. 4 is an XX sectional view showing another example of the recess 3a. The concave portion 3a is provided along the curved outer surface of the grip portion 3, but is different from the case of FIG. 3 in that the concave portion 3a is provided not in the entire circumferential direction of the grip portion 3 but partially. Specifically, when the grip portion 3 is gripped mainly with the thumb and forefinger (or middle finger), the concave portions 3a are formed only on the portions where the force pinched by these fingers is most applied, that is, on both sides of the grip portion 3. Yes.

  Note that, as shown by a thick line F in FIG. 2, the surface of the grip portion 3 is not flush, but protrudes in a slope shape downward. Thereby, it becomes a shape along the shape of a palm, and a feeling of fitting at the time of grasping grip part 3 can be improved.

  FIG. 5 is a principal end view showing the upper part of the bottle-type container 1. The cylindrical neck 4 is connected to the container body 2 with the narrowed upper part of the container body 2 as a root. The neck portion 4 projecting upward from the base has a mouth portion 4 a that opens at the top thereof, and the mouth portion 4 a is spatially connected to the internal space of the bottle-type container 1. A flange portion 5 is provided on the way from the base of the neck portion 4 to the top portion of the neck portion 4, and the flange portion 5 protrudes sideways from the side surface of the neck portion 4. A screw for attaching a cap (not shown) is formed on the surface (outer surface) of the upper neck portion 4b located above the flange portion 5. In addition, the lower surface of the flange portion 5 is connected to the surface (side surface) of the lower neck portion 4 c located below the flange portion 5 in a curved shape in consideration of ease of gripping when the bottle-shaped container 1 is lifted. The lower end of the lower neck portion 4c is connected to the container body portion 2. The interval D between the base and the flange portion 5 is an interval at which the neck portion can be gripped by the thumb and forefinger, for example, 0.4 cm to 2.0 cm. Preferably it is set to 0.7 cm to 1.8 cm, more preferably 1.0 cm to 1.5 cm.

  Thus, according to the present embodiment, as shown in FIG. 6, when the bottle-shaped container 1 is carried by holding the grip portion 3, the thumb and index finger (or middle finger) are placed in the recess 3 a provided on the surface of the grip portion 3. ) Fits easily and is easy to grip and difficult to slip. Therefore, when carrying a large-capacity / large-sized bottle-type container 1, there is an effect that it is easy to carry.

  Further, according to the present embodiment, as shown in FIG. 7, when the hand (middle finger, ring finger and little finger) is applied to the inclined upper portion of the container body portion 2 and the neck portion 4 is gripped to lift the bottle-shaped container 1 The thumb and forefinger are easily fitted to the curved surface connecting the flange portion 5 and the lower neck portion 4c (a part of the neck portion 4). Therefore, when taking out the large-capacity / large bottle-type container 1 from the packing box, there is an effect that it is easy to lift.
