Description

The present invention relates to bottle containers.

For example, a bottle container for beverages is generally provided with an annular label so as to cover the side surface of the main body portion containing the contents. Such labels include, for example, a "wound label" in which the ends are joined together after being wrapped around the side surface of the main body, and a "shrink label" in which the label is fixed to the main body by being heated and shrunk. etc.

The main body is often made of synthetic resin such as polyethylene terephthalate. It is feared that such a main body made of synthetic resin may be deformed due to the weight of the contained contents, the force of gripping by the user during use, and the like. For this reason, ribs are formed in the main body so as to reinforce the main body in a recessed manner.

Reinforcing ribs are also formed on the portion of the main body that is covered by the label. However, in such a configuration, when the label is attached, the label is deformed so as to recede inward along the ribs, so there is a problem that the appearance of the label is spoiled. Such label deformation is particularly likely to occur when the label is a shrink label.

Therefore, in the bottle container (synthetic resin container) described in Patent Document 1 below, wrinkles, etc. It prevents the occurrence of poor appearance. Specifically, ribs formed so as to extend along the circumferential direction of the main body portion are composed of a main groove portion, a sub-groove portion formed so as to be different from the main groove portion, and between the main groove portion and the sub-groove portion. and a slant groove connecting the .

In the bottle container described in Patent Literature 1, the reinforcing rib is formed so as to extend seamlessly over the entire circumference of the body portion. In other words, the portion of the label that is not directly supported from the back side by the body portion is configured to extend annularly without a break along the circumferential direction. In such a configuration, it is considered difficult to sufficiently suppress deformation of the label.

In order to suppress the deformation of the label, it is conceivable that the portion of the main body covered by the label is not formed with any reinforcing ribs. However, with such a configuration, the strength of the main body is significantly reduced.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottle container capable of securing the strength of the main body and suppressing deformation of the label.

A bottle container according to the present invention comprises a main body portion for containing contents, and an annular label provided so as to cover at least a part of the range along the longitudinal direction of the main body portion along the circumferential direction of the main body portion. , provided. A pair of reinforcing ribs extending linearly along the circumferential direction, which are ribs formed to recede inward in a concave shape, are formed in the portion of the main body covered by the label, along the circumferential direction. They are formed so as to be spaced apart from each other. In this bottle container, each reinforcing rib is formed such that the dimension of the space along the circumferential direction is larger than the dimension of the reinforcing rib along the longitudinal direction.

In the bottle container having such a structure, a pair of reinforcing ribs are formed in a portion of the body portion covered with the label, thereby ensuring the strength of the body portion. Moreover, the pair of reinforcing ribs do not extend continuously in a ring shape along the circumferential direction, but are formed so as to be spaced apart from each other along the circumferential direction. If the portion of the main body portion with the above-mentioned interval is called an "intermittent portion", the label is directly supported from the back side by the main body portion at each of the two intermittent portions. Therefore, when the label is attached, even at a position directly above the reinforcing rib, deformation of the label that recedes inward can be suppressed more than in the conventional case.

ADVANTAGE OF THE INVENTION According to this invention, the bottle container which can suppress the deformation|transformation of a label while ensuring the intensity|strength of a main-body part is provided.

FIG. 1 is a front view of the bottle container according to the present embodiment. FIG. 2 is a top view of the bottle container according to the present embodiment. FIG. 3 is a front view of the bottle container according to the present embodiment. FIG. 4 is a side view of the bottle container according to the present embodiment.

Hereinafter, this embodiment will be described with reference to the accompanying drawings. In order to facilitate understanding of the description, the same constituent elements in each drawing are denoted by the same reference numerals as much as possible, and overlapping descriptions are omitted.

The bottle container 10 according to this embodiment is configured as a container for containing a beverage as a content. However, the bottle container 10 is not particularly limited as long as it is a container for containing some liquid therein.

FIG. 1 shows the overall configuration of the bottle container 10. As shown in FIG. The bottle container 10 is integrally made of, for example, polyethylene terephthalate. The bottle container 10 includes a body portion 11, an outlet portion 12, and a label LB.

The body portion 11 is a portion that accommodates liquid content therein. As shown in FIG. 2, when the main body 11 is viewed from above, the outer shape of the main body 11 is substantially rectangular. The main body 11 has long side surfaces S11 and S12 facing each other, and short side surfaces S21 and S22 perpendicular thereto and facing each other. Adjacent corner portions of these four side surfaces S11 and the like are smoothly curved. As described above, in the bottle container 10 according to the present embodiment, the cross-sectional shape of the main body 11 when cut perpendicularly to the longitudinal direction thereof is a rectangular shape having long sides and short sides. Each corner portion in is curved. As will be described later, intermittent portions 21 are provided on side surfaces S11 and S12 on the short sides facing each other.

As shown in FIG. 1, the body portion 11 is formed to stand with its longitudinal direction along the vertical direction. An outlet portion 12 is formed in the body portion 11 at the upper end position along the longitudinal direction. The cross-sectional shape of the main body 11 when cut along a plane perpendicular to the longitudinal direction is substantially the same rectangular shape as the shape shown in FIG. 2 over substantially the entirety along the same direction. However, in the vicinity of the exit portion 12, the cross-sectional shape gradually becomes smaller as the exit portion 12 is approached.

The outlet part 12 is a part formed as an outlet for the contents. The outlet portion 12 is formed in a substantially cylindrical shape. The internal space of the outlet portion 12 and the internal space of the main body portion 11 communicate with each other. A cap (not shown) is attached to the outlet portion 12 to prevent the contents from spilling out.

The label LB is an annular member provided so as to cover a part of the lengthwise range of the main body 11 along the circumferential direction of the main body 11 . The label LB is made by forming a flexible material such as polystyrene into a sheet. The label LB is provided for the purpose of printing and displaying, for example, the product name of the contents, and improving the design of the bottle container 10 .

The label LB may be provided so as to cover the entire range along the longitudinal direction of the body portion 11 . The label LB of this embodiment is a shrink label that is fixed to the main body 11 by being heated and shrunk. The label LB may be a “wound label” in which the ends are joined together after being wound around the side surface of the main body 11 .

FIG. 3 is a drawing of the main body 11 with the label LB removed, viewed from the long side S11 side. FIG. 4 is a drawing of the main body 11 with the label LB removed, viewed from the short side S21 side. 3 and 4, the upper end of the portion of the main body 11 covered by the label LB is indicated by a dotted line DL1, and the lower end of the same portion is indicated by a dotted line DL2.

As shown in FIGS. 3 and 4, a plurality of ribs 20 and 30 are formed on the side surface of the body portion 11. As shown in FIGS. These are all formed in order to secure the strength of the body portion 11 and are formed so as to recede toward the inside of the body portion 11 in a concave shape.

The rib 20 is formed so as to linearly extend along the circumferential direction of the body portion 11 at a height position covered by the label LB in the body portion 11 . Two ribs 20 are formed. The pair of ribs 20 are formed so as to be spaced apart from each other in the circumferential direction at the same height position on the body portion 11 . Each rib 20 corresponds to the "reinforcing rib" in this embodiment.

A distance H1 from the upper end of the main body 11 to the center of the rib 20 along the longitudinal direction of the main body 11 is equal to a distance H2 from the center of the rib 20 to the lower end of the main body 11 along the same direction. In other words, the pair of ribs 20, which are reinforcing ribs, are formed at the center of the main body 11 along the longitudinal direction. In the present embodiment, the pair of ribs 20, which are reinforcing ribs, are formed at the central position along the longitudinal direction of the body portion 11. However, the present invention is not limited to this. good.

The portion sandwiched between the pair of ribs 20 in the main body portion 11, that is, the portion of the above-mentioned "gap" is hereinafter also referred to as the "intermittent portion 21". As shown in FIG. 4, one intermittent portion 21 is formed entirely on the side surface S21. The intermittent portion 21 is formed at the center of the body portion 11 in the left-right direction when viewed from the direction of FIG. 4 .

A similar intermittent portion 21 is also formed on the side surface S22 on the back side of the paper surface of FIG. The position and shape of the intermittent portion 21 when viewed from the side surface S22 are the same as the position and shape of the intermittent portion 21 shown in FIG.

As shown in FIG. 3, the intermittent portion 21 is not formed on the side surface S11, and the rib 20 extends over the entire left and right sides of the side surface S11. The same applies to the side surface S12 on the far side of the paper surface of FIG. Thus, one of the pair of ribs 20 (right rib 20 in FIG. 4) is formed to extend from side S21 to side S22 via side S11. The other of the pair of ribs 20 (left rib 20 in FIG. 4) is formed to extend from side S21 to side S22 via side S12. As described above, the two intermittent portions 21 have the same shape. Therefore, the dimensions of each rib 20 along the circumferential direction are equal to each other. In this embodiment, the dimensions of the ribs 20 along the circumferential direction are equal to each other, but the dimensions are not limited to this and may be different from each other. Moreover, the dimensions of the ribs 20 along the longitudinal direction of the body portion 11 may be different from each other. If the pair of ribs 20 are formed so as to sandwich the intermittent portion 21 and extend to the side surfaces S11 and S12, the ribs 20 can be appropriately modified as described above.

The rib 30 is formed at a height position different from that of the rib 20 along the longitudinal direction of the body portion 11 . Like the ribs 20 , the ribs 30 are also formed so as to extend linearly along the circumferential direction of the body portion 11 . However, the ribs 30 are formed only on the side surfaces S11 and S12, and are not formed on the side surfaces S21 and S22. The ribs 30 are arranged three by three along the longitudinal direction of the body portion 11 on each of the upper side and the lower side of the ribs 20 . Some ribs 30 are also formed outside the range covered by the label LB in the body portion 11 . Each rib 30 corresponds to the "additional reinforcing rib" in this embodiment. The number and arrangement of ribs 30 may differ from those shown in FIGS.

As described above, in the bottle container 10 according to the present embodiment, a plurality of concave ribs 20 and the like are formed in the range covered by the label LB in the body portion 11 .

By the way, in the bottle container 10 having such a configuration, when the label LB is attached to the body portion 11, there is a concern that the label LB is deformed so as to recede inward along the ribs 20 and the like. Such deformation of the label LB is not preferable because it spoils the appearance of the label LB. Such deformation is particularly likely to occur when the label LB is a shrink label as in this embodiment.

Therefore, in the bottle container 10 of the present embodiment, deformation of the label LB is suppressed by devising the shape of the rib 20 and the like.

The device will be explained. “L1” shown in FIG. 4 is the dimension of the intermittent portion 21 along the circumferential direction of the body portion 11 . In other words, it is the dimension of the "gap" between the ribs 20 adjacent to each other. Also, “L2” shown in FIG. 4 is the dimension of the rib 20 along the longitudinal direction of the body portion 11 . L2 is constant over the entire rib 20 regardless of the position along the circumferential direction. In this embodiment, each rib 20, which is a reinforcing rib, is formed such that L1 is larger than L2.

The label LB is directly supported from the back surface by the body portion 11 at the position directly above the intermittent portion 21 that is the break of the rib 20 . Therefore, when the label LB is attached to the body portion 11, deformation of the label LB such as retreating inward is suppressed not only at the position directly above the intermittent portion 21 but also at the position directly above the rib 20. be.

If the intermittent portion 21 is formed relatively narrow so that L1 is equal to or less than L2, the range in which the label LB is directly supported from the back surface becomes too narrow, so that the label LB is deformed when attached. cannot be sufficiently suppressed. Therefore, in the present embodiment, deformation of the label LB can be sufficiently suppressed by forming each rib 20 so that L1 is larger than L2.

As described above, in this embodiment, the lengths of the two ribs 20, that is, the dimensions of the ribs 20 along the circumferential direction are equal to each other. In addition, the circumferential dimension of one intermittent portion 21 provided on the side surface S21 and the circumferential dimension of the other intermittent portion 21 provided on the side surface S22 are equal to each other. In such a configuration, the label LB is similarly supported from the back side at two mutually opposing portions of the side surfaces of the body portion 11 . Since the label LB is evenly supported at two locations, deformation of the label LB during attachment can be further suppressed. In the present embodiment, the dimension along the circumferential direction of one intermittent portion 21 provided on the side surface S21 and the dimension along the circumferential direction of the other intermittent portion 21 provided on the side surface S22 are equal to each other. However, it is not limited to this, and may not be equal. That is, the two ribs 20 may have different lengths as long as they are provided over the side surface S21 and the side surface S22. It doesn't matter if it's off. In the present embodiment, from the viewpoint of achieving both suppression of deformation of the label LB and strength of the main body 11, the intermittent portions 21 are preferably provided on the side surfaces S21 and S22, which are the short sides.

“L3” shown in FIG. 4 is the width dimension of the body portion 11 . Specifically, the "width dimension" referred to here is when the main body 11 is viewed along the direction in which the two intermittent portions 21 overlap each other, that is, when the main body 11 is viewed as shown in FIG. , the dimension of the main body 11 along the direction perpendicular to the longitudinal direction of the main body 11 (that is, the horizontal direction in FIG. 4). Here, "overlapping" may be a state in which the intermittent portions 21 completely overlap or a state in which they partially overlap. In addition, the "width dimension" referred to here can be rephrased as the dimension of the short sides facing each other in the cross section of the main body 11 in this embodiment taken perpendicularly to the longitudinal direction. In this embodiment, each rib 20 is formed such that the dimension (L1) along the circumferential direction of the intermittent portion 21 is smaller than half the width dimension (L3) of the main body portion 11 .

If the intermittent portion 21 is formed relatively wide so that L1 is half or more of L3, it is possible to further suppress deformation of the label LB when it is attached. However, in this case, the reinforcement of the main body portion 11 by the ribs 20 is insufficient. As a result, the main body 11 is likely to be greatly deformed due to the weight of the contents, the gripping force of the user, and the like. In order to sufficiently secure the strength of the body portion 11, the ribs 20 are provided in a range extending from the side surface S21 to the side surface S22 via the side surface S12 and from the side surface S21 to the side surface S22 via the side surface S11, as in the present embodiment. It is preferable that L1<L3×1/2 be established after forming in each of the extending ranges.

As described above, in order to balance the effect of securing the strength of the main body 11 and the effect of suppressing the deformation of the label LB, L1<L3×1/2 as in the present embodiment. Moreover, it is preferable to form each rib 20 so that L1>L2.

As described above, in this embodiment, the pair of ribs 20, which are reinforcing ribs, are formed at the center of the main body 11 along the longitudinal direction. Further, the position where the rib 20 is formed is not limited to the center, and may be near the center. This position is the position where the reinforcement of the body portion 11 by the ribs 20 can be most effectively performed, and is also the position where the possibility of being covered with the label LB is high. By forming the rib 20 at such a height position, it is possible to efficiently achieve both the effect of securing the strength of the main body 11 and the effect of suppressing deformation of the label LB. The vicinity of the center where the rib 20 is formed is roughly the position where the user grips the bottle container 10 when pouring. By providing the rib 20 near the center, deformation of the main body 10 in a direction perpendicular to the longitudinal direction of the main body 11 (a direction along L3 in FIG. 4) can be suppressed.

In this embodiment, not only ribs 20, which are reinforcing ribs, but also ribs 30, which are additional reinforcing ribs, are formed. With such a configuration, the strength of the body portion 11 can be further increased.

In this embodiment, only one pair of ribs 20, which are reinforcing ribs, are formed in the area covered by the label LB in the main body 11. As shown in FIG. Instead of such a mode, a mode in which a pair of ribs is formed at each of a plurality of height positions along the longitudinal direction of the body portion 11 within the same range may be adopted.

In the above, an example in which the outer shape of the main body 11 when viewed from above is substantially rectangular as shown in FIG. 2 has been described. However, the outer shape of the body portion 11 may have a shape different from this. For example, the outer shape of the main body 11 when viewed from above may be circular or elliptical. As a modification, when the outer shape of the body portion 11 is elliptical, the side surfaces S11 and S12 in this embodiment correspond to two sides with a small curvature along the major axis, and the side surfaces S21 and S22 correspond to the minor axis. The two sides along which the curvature is large correspond to it.

The present embodiment has been described above with reference to specific examples. However, the present disclosure is not limited to these specific examples. Design modifications to these specific examples by those skilled in the art are also included in the scope of the present disclosure as long as they have the features of the present disclosure. Each element included in each specific example described above and its arrangement, conditions, shape, etc. are not limited to those illustrated and can be changed as appropriate. As long as there is no technical contradiction, the combination of the elements included in the specific examples described above can be changed as appropriate.
