Description

  The present invention relates to a container and an article including the same.

  A container made of a synthetic resin such as PET (polyethylene terephthalate) is known as a beverage container. From the viewpoint of resource saving, there is a need to reduce the amount of materials used to form the container. To achieve this, the required strength must be ensured even when the container thickness is reduced. Don't be. In particular, in a large container such as a 2 liter container, when the wall thickness is reduced, the container may be deformed when the container is opened or when a beverage is poured, and this is a major problem. Yes.

  On the other hand, a large container such as a 2 liter container has a large weight and size and is generally difficult to hold. In addition, in a state where the beverage in the container is reduced to about half, when the beverage is poured into the glass, the mouth side suddenly falls due to the movement of the center of gravity. Therefore, a large container such as a 2 liter container is required to have improved retention.

  Although the applicant does not recognize prior art documents directly related to the present application, Patent Document 1 discloses a plastic bottle container having a concave gripping portion.

  In this specification, expressions that mean directions such as “longitudinal direction”, “lateral direction”, “upper”, “lower”, etc. mean directions in the case where the container is arranged in an upright state. The upright state is a state in which the container is arranged so that the mouth of the container is on the top.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

  1, 2, and 3 are a front view, a side view, and a top view, respectively, of a container 100 according to a preferred embodiment of the present invention. FIG. 4 is a cross-sectional view of the container 100 taken along the line A-A ′ of FIG. 1. FIG. 5 is an enlarged view of a part of FIG. The container 100 can be traded, for example, alone or as an article filled with a liquid such as a beverage. The container 100 can be made of a synthetic resin such as PET.

  The container 100 includes a trunk portion 10 and a mouth portion 20. The trunk | drum 10 has two 1st side surfaces 11 and 12 which oppose, and two 2nd side surfaces 13 and 14 which oppose. The first side surfaces 11 and 12 and the second side surfaces 13 and 14 are perpendicular to each other. One first side surface 11 and two second side surfaces 13 and 14 are connected by a curved surface 15, and the other first side surface 12 and two second side surfaces 13 and 14 are connected by a curved surface 15. Such a container 100 may be referred to as a square container or a square bottle. One first side surface 11 and the other first side surface 12 may typically have the same shape. Further, one second side surface 13 and the other second side surface 14 can typically have the same shape.

  In the vicinity of the vertical center of each of the two first side surfaces 11 and 12, a gripping recess 30 that is gripped by a fingertip (end node) and a peripheral portion 40 that surrounds the gripping recess 30 over its entire circumference are arranged. ing. The holding recesses 30 disposed on one first surface 11 are recessed in the direction of the opposing first side surface 12 rather than the peripheral portion 40. Similarly, the holding concave portion 30 disposed on the other first surface 12 is recessed in the direction of the first side surface 11 which is opposed to the peripheral portion 40. It is preferable that a part or the whole of the region inside the boundary B between the holding recess 30 and the peripheral portion 40 has a roughened region R. The surface roughness of the peripheral portion 40 is smaller than the surface roughness of the roughened region R. Here, the boundary B may be a set of positions where the inclination starts from the peripheral portion 40 side toward the gripping concave portion 30 side. The vicinity of the central portion in the vertical direction of the first side surfaces 11 and 12 can be a range in which the distance from the lower end of the container 100 is 0.3 h to 0.7 h when the height of the container 100 is h.

  By making the surface roughness of the peripheral portion 40 smaller than the surface roughness of the roughened region R, the roughened region can be obtained while sliding the fingertip along the surface of the peripheral portion 40 when trying to grip the container 100. The fingertip can be brought to the holding recess 30 including R. In contrast, when the surface roughness of the peripheral portion 40 is as large as the roughened region R, it is difficult to find the gripping recess 30 with the touch of the fingertip, and the gripping recess 30 is viewed properly. It is necessary to hold the holding recess 30 with the fingertip.

  Further, by providing the roughened region R in the gripping concave portion 30, slipping of the fingertip with respect to the gripping concave portion 30 can be suppressed, and the gripping concave portion 30 of the container 100 can be firmly held by the fingertip.

  JP-A-6-135444 discloses a round bottle, that is, a bottle having a cylindrical body. The bottle disclosed in Japanese Patent Application Laid-Open No. 6-135444 is perpendicular to the two opposing first side surfaces 11 and 12 and the two first side surfaces 13 and 14, such as the container 100 in a preferred embodiment of the present invention. This is different from a rectangular container having two second side surfaces 13 and 14 facing each other. Further, in the bottle disclosed in Japanese Patent Laid-Open No. 6-135444, the first side surfaces 11 and 12 are provided with a gripping concave portion 30 that is gripped by a fingertip and a peripheral portion 40 that surrounds the gripping concave portion 30 over its entire circumference. The arrangement is different from the configuration in which the holding recessed portion 30 is recessed in the direction of the first side surface 11 or 12 that is opposed to the peripheral portion 40. Furthermore, the bottle disclosed in Japanese Patent Application Laid-Open No. 6-135444 has no distinction between a portion to be gripped by the fingertip and a portion to be gripped by the palm-side portion from the fingertip, and drops on both portions. An uneven pattern for prevention is formed.

  The holding recess 30 preferably has a shape in which the lateral width W decreases from the upper part toward the lower part. This is because the lengths of the middle finger and the ring finger are different. By adopting a shape in which the lateral width W decreases from the upper part to the lower part of the gripping recess 30, the tip of the middle finger and the tip of the ring finger are side surfaces of the gripping recess 30 as shown in FIG. 6. Therefore, sudden rotation of the container 100 (particularly, rotation due to movement of the center of gravity when the beverage is poured into a glass in a state where the content of the beverage is about half) can be prevented, and the container 100 can be stably held. it can.

  The maximum vertical width H of the holding recess 30 is preferably in the range of 20 to 50 mm, and more preferably in the range of 30 to 40 mm. According to such a vertical maximum width H, the middle fingertip (end node) and the ring finger tip (end node) are accommodated in the holding recess 30 of one of the two first side surfaces 11 and 12, and the container 100 Can be held stably. In the other gripping recess 30 of the two first side surfaces 11, 12, a thumb is typically contained. If the maximum vertical width H is too large, the gap between the gripping recesses 30 becomes large with respect to the fingertip, and the holding becomes unstable. If it is too small, the fingertips will not fit well and the holding will be unstable.

  The container 100 may have a convex portion 50 that extends around the entire circumference of the body portion 10 below the gripping concave portion 30. The convex portion 50 is useful for increasing the strength of the container 100. The convex portion 50 includes a corrugated portion that is undulated in the vertical direction, and the corrugated portion includes a first trough portion 51, two crest portions 52, and two second trough portions 53 with respect to one gripping concave portion 30. Can be included. The two peak portions 52 are arranged so as to sandwich the first valley portion 51, and the two peak portions 52 can be arranged between the first valley portion 51 and the two second valley portions 53. The first trough portion 51 may be located immediately below the center of the gripping recess 30, and the peak portion 52 may be disposed adjacent to the gripping recess 30. The configuration in which the convex portion 50 includes the corrugated portion is useful for further increasing the strength of the container 100. The configuration in which the corrugated portion includes the first valley portion 51, the two peak portions 52, and the two second valley portions 53 is advantageous in order to suppress sudden rotation of the container 100 when pouring a beverage by the thumb. . As shown in FIG. 7, the peak portion 52 fits inside the first joint of the thumb, and the portion from the peak portion 52 to the first valley portion 51 is the last node of the thumb (from the first joint to the tip of the finger). Part). Moreover, the part from the peak part 52 to the 2nd trough part 53 can fit the middle clause of a thumb (part between a 1st joint and a 2nd joint).

  The corrugated portion of the convex portion 50 can include a mountain portion 54 disposed on the second side surfaces 13 and 14. The mountain portion 54 can be disposed between the second valley portion 53 and the second valley portion 53. The crest 54 is advantageous for increasing the strength of the container 100, particularly the strength of the second side surfaces 13 and 14. In this example, the corrugated portion includes the first trough portion 51, the crest portion 52, the second trough portion 53, and the crest portion 54, but the corrugated portion is configured only by the second trough portion 53 and the crest portion 54. However, the strength of the container 100 can be improved. In addition, the applicant has the convex part 50 formed over the perimeter of the trunk | drum 10 under the recessed part 30 for a grip arrange | positioned in the 1st side surfaces 11 and 12, and this corrugated part is a 2nd side surface. The prior art which denies the patentability of the structure containing the trough part 53 and the peak part 52 in 13 and 14 is not recognized.
