  In the case of a large-capacity bottle filled with contents, in addition to the increase in weight, the size of the container also becomes large, so those having a grip function to be easily held by one hand are widely used. One of them is a grip bottle with a separate handle attached to the container body. However, with such a bottle, the amount of resin increases by the amount of the handle, and the process for attaching the handle is required, which increases the manufacturing cost. In order to solve this problem and to meet the demands for environmental protection, the container forming the housing space is provided with two inward recessed finger depressions, and a part of the two finger indented recesses and the two fingers concerned. A grip bottle is known in which a grip is integrally formed by a columnar wall projecting outward between hooking recesses.

  This grip bottle does not require the process of attaching the handle, and is easy to mold, so that the increase in manufacturing cost can be suppressed. In addition, the consumer can hold the grip bottle easily and safely by putting a fingertip in the two finger hook recesses formed in the container and holding it so as to wrap the columnar wall between the two finger hook recesses. Therefore, many products that store seasonings and oils such as soy sauce used at home in large-capacity grip bottles are stored at stores.

  In Patent Document 1, a recess is formed in the opposing region around the body of the container body, and the entire region between the two is a gripping portion, and the hooking portion at the time of gripping in the recessed portions on both sides A grip bottle is described which is provided with two steps to be formed. According to this document, by dividing the concave portion provided in the body portion of the container main body by two steps, it is possible to securely hold the fingertip without applying a force.

At the same time, an approach portion 51 closest to the axis X side in each of the finger holding concave portions 20, 20 exists in the half body region 50. In FIG. 4, an imaginary circle P <b> 2 circumscribing the approach portions 51, 51 of the both finger holding concave portions 20, 20 is drawn with the axis X as the center. The diameter D1 of the imaginary circle P2 is preferably 20% to 50%, and more preferably 30% to 40% of the diameter D2 of the trunk 4. If the diameter D1 of the virtual circle P2 is smaller than 20% of the diameter D2 of the trunk 4, the both finger holding concave portions 20, 20 enter the trunk 4 side too much, and the diameter D1 of the virtual circle P2 is the trunk 4 If it is larger than 50% of the diameter D2, the both finger rests 20, 20 will be too far from the body 4 side.

  If the diameter D1 of the imaginary circle P2 is 20% to 50% of the diameter D2 of the trunk 4, the two finger-hold concaves 20, 20 do not excessively enter the trunk 4 side, and the two-finger-hold concaves 20 and 20 do not separate too much from the trunk | drum 4 side. Thereby, the accommodation area in the cross section of the trunk | drum 4 does not become small, and it is not necessary to enlarge height. Furthermore, when the grip bottle 1 is held, the force can be easily applied, and the sense of stability is improved.

  As shown in FIG. 2, each finger recess 20 has a bottom portion 28 which is the deepest portion, an annular surface 29 formed around the bottom portion 28, and a substantially C shape formed further outside the annular surface 29. And the circumferential surface 30 of the An annular segment 31 is formed between the annular surface 29 and the circumferential surface 30. The bottom portion 28 is formed with three depressions 32 aligned in the longitudinal direction to increase the strength of the bottom portion 28. The annular surface 29 is formed with a plurality of inner ribs 33 (ribs) radially extending about the bottom portion 28. The inner ribs 33 extend at substantially equal intervals around the bottom 28 and extend from the bottom 28 to the section 31. In the present embodiment, twelve inner ribs 33 are formed on the annular surface 29.

  The length of the inner rib 33 is preferably 8 to 30 mm, more preferably 13 to 23 mm. The width of the inner rib 33 is preferably 1.5 to 3.5 mm, more preferably 2.0 to 3.0 mm. The depth of the inner rib 33 is preferably 0.5 to 2.0 mm, more preferably 1.0 to 1.5 mm. The number of the inner ribs 33 formed around the bottom 28 is preferably seven to fifteen.

  A plurality of outer ribs 34 (ribs) extending outward are also formed on the substantially C-shaped peripheral surface 30 outside the annular surface 29. Among the plurality of outer ribs 34, the plurality of outer ribs 34 on the upper and lower sides extend outward, and the plurality of outer ribs 34 on the lateral sides extend in the same lateral direction. In the present embodiment, the plurality of outer ribs 34 on the upper and lower sides are configured by three each in the upper and lower sides, and the plurality of outer ribs 34 on the lateral side are configured by three. Each inner rib 33 and each outer rib 34 are arranged such that the outer end of each inner rib 33 and the inner end of each outer rib 34 face each other except for some of the plurality of inner ribs 33. .

  The length of the outer rib 34 is preferably 7 to 22 mm, more preferably 10 to 19 mm. The width of the outer rib 34 is preferably 2 to 6 mm, more preferably 3 to 5 mm. The depth of the outer rib 34 is preferably 1.0 to 3.0 mm, more preferably 1.5 to 2.5 mm. The number of outer ribs 34 formed around the inner ribs 33 is preferably four to twelve. By forming the inner ribs 33 and the outer ribs 34 with such dimensions and numbers, it is possible to effectively suppress the buckling phenomenon in which the respective finger-hold concave portions 20 project outward due to an impact at the time of dropping or the like. .

  A drop test was conducted to confirm the improvement effect of the buckling phenomenon. As an example, the grip bottle of this embodiment was manufactured, and as a comparative example, a grip bottle having the same shape as that of this embodiment except that there was no rib in each finger hook recess was manufactured. A drop test was conducted after filling with water at 30 ° C. and storing it at normal temperature for 1 day. Three grip bottles were dropped from the position of height 40 cm in the vertical state and the horizontal state, and the presence or absence of the buckling phenomenon was confirmed. As a result, in the example, no buckling phenomenon was observed in all the grip bottles, and a remarkable buckling phenomenon was observed in the comparative example.

  According to the grip bottle 1 of the present embodiment, the grip 22 is formed so that the value obtained by dividing the grip width T by the length L in the grip axial direction is 0.6 to 0.8. The balance between the grip width and the grip length resulting from the grip axial direction length L is good. Therefore, the ease of gripping when holding the grip bottle 1 is improved, and the finger can be held in a stable state without being overloaded. Furthermore, since the columnar wall 21 of the grip 22 is formed so as to enter inward, the fit when holding the grip 22 is improved, and the grip bottle 1 can be held in a more stable state.

  By inclining each finger hook surface 27 at a steep angle toward the bottom portion 28 of each finger hook concave portion 20, when the finger is turned into both finger hook concave portions 20, the finger is easily hooked. Therefore, when the large capacity grip bottle 1 is lifted, it can be held firmly, and the sense of stability when holding the grip bottle 1 can be enhanced.

  Since a plurality of ribs 33 and 34 radially extending around the bottom 28 of the two finger hooks 20 are formed around the bottom 28, the finger hook 20 protrudes outward due to an impact at the time of dropping or the like. Can suppress the buckling phenomenon. At the same time, slippage of the finger in each finger rest 20 can be prevented. In particular, in the present embodiment, since the inner inner rib 33 and the outer outer rib 34 are formed in different areas, the buckling phenomenon can be more effectively reduced, and the finger when gripping the grip 22 can be reduced more effectively. The sense of can be improved.
