Description

Bottle container

This creation is about a bottle container.

Conventionally, as a container for a liquid material such as a liquid lotion, a liquid softener, or a liquid bleach, a bottle container made of a synthetic resin is generally used.

If a gas absorbing content is present in the previous bottle container, there is a case where the gas in the head space is reduced and the pressure in the container is lowered to cause deformation of the container.

Since the gas in the head space which is the space left above the container is absorbed, the pressure in the head space is reduced to a pressure lower than atmospheric pressure, whereby undesired depression or deformation occurs on the container. In particular, in the vicinity of the shoulder or shoulder portion of the container body portion, the spout is provided in the mouth and neck portion and the spout is provided in the shape of the outlet portion which is bulged in the vicinity of the fitting portion or the fitting portion. In the case of a wider shape, the amount of gas absorbed in the headspace is large.

If the container of the product displayed in front of the store produces such a depression or the like, the image of the product is deteriorated. Regarding this problem, in addition to the case where the content is gas absorbing, it may also occur when the liquid is cooled after the high temperature liquid is injected and sealed.

The art proposes to solve the problem that the inside of the bottle container is to be solved by changing the curvature of the front side of the horizontal section of the main body portion and the curvature of the back side, and deliberately setting the side which is deformed corresponding to the decompression. The problem of deformation caused by pressure reduction (Patent Document 1).

Further, the industry has also proposed a technique in which a recess guide line is provided on at least one of a front surface and a rear side wall of a main body portion constituting a bottle container, and the main body portion is formed to be recessed from the bottom portion and the shoulder portion. The guide wire is gradually reduced in shape of the diameter, and the deformed portion is specified to minimize the deterioration of the appearance (Patent Document 2).

Patent Document 2: Japanese Patent Laid-Open Publication No. 2009-132436

Patent Document 3: Japanese Patent Laid-Open Publication No. 2002-362525

In the technique of Patent Document 1, since the curvature of the front side and the curvature of the back side must be changed, the shape of the container is restricted, and for example, the container having a shape symmetrical with respect to the front side and the back side cannot be used. Patent Document 1 describes a rib having a lateral strip shape. However, the rib of the transverse strip shape is provided on the back side which is easily deformed by reducing the curvature.

According to the technique of Patent Document 2, when the label is attached so as to cover the concave guide line, the label is irregularly deformed at the position of the concave guide line, and if the label is attached to avoid the concave guide line, the label can be attached. The scope of the label is limited. Further, the recessed guide line of Patent Document 2 is not a concave rib.

Further, Patent Document 3 discloses a technique of providing ribs on a squeeze container. However, the ribs are provided to increase the breaking strength of the container, and are formed on the opposite side of the body portion of the container.

The object of the present invention is to provide a bottle container which can solve the problems of the prior art described above.

Hereinafter, the present creation will be described based on a preferred embodiment.

As shown in Fig. 1, the bottle container 1 (hereinafter also referred to simply as the container 1) according to the first embodiment of the present invention includes a container body 2 including a neck portion 3 having a opening portion 31, a bottom portion 4, and a main body. Department 5. The container body 2 has a mouth neck 3 above and a bottom 4 below. The mouth and neck 3 has an opening at the upper end.

The neck portion 3 has a cylindrical shape and has an opening portion 31 at the upper end. The mouth and neck 3 is attached with a cover which can seal the inside of the container body 2. The configuration of the cover attached to the neck portion 3 is not particularly limited, and for example, a take-off cover 80 having a discharge cylinder 82 and a metering cover 86 screwed to the discharge cover 80 as shown in FIG. 1 can be cited. And so on. The bottom 4 is formed in such a manner that the bottle container 1 can be erected on a horizontal surface.

In the present specification, the upper portion is arranged such that the bottom of the container body is placed on a horizontal surface. When the bottle container is erected, it is oriented upward in the vertical direction, and the lower side is placed in the direction in which the bottom of the container body is placed on the horizontal plane so that the bottle container is erected downward in the vertical direction.

The main body portion 5 is located between the neck portion 3 and the bottom portion 4 in the height direction of the container body 2. As shown in FIG. 2, the main body portion 5 has a flat shape in which the horizontal cross section has a long axis direction X and a short axis direction Y. The main body portion 5 includes a shoulder portion 50 that expands in a horizontal direction from the lower end of the mouth neck portion 3, an inner surface a that faces the front wall 51 and the rear wall 52, and two in the long axis direction X. One of the pair of side walls (the first side wall 53 and the second side wall 54) has a grip portion 7 formed from the shoulder portion 50 to the lower portion of the bottle in the second side wall 54 (one side wall) side in the longitudinal direction X. Further, a horizontal groove 6 (concave rib) including a groove is formed in the front wall 51. The first side wall 53 and the second side wall 54 are formed between the front wall 51 and the rear wall 52 in the circumferential direction of the main body portion 5.

The interface between the front wall 51 and the rear wall 52 and the first side wall 53 and the second side wall 54 may be smoothly connected, or may be connected via an interface having a large curvature. Alternatively, they may be connected via ridge lines 56, 57 as shown in FIG.

As described above, in the container 1 of the present embodiment, the grip portion 7 for gripping the container is held in the hand, and the through hole (the grip space) for forming the grip portion 7 is formed in the main body portion 5. 71. The through hole (grip space) 71 for forming the grip portion 7 is formed by connecting the cylindrical wall 55 of the main body portion 5 between the front wall 51 and the rear wall 52.

As shown in FIG. 2, the main body portion 5 has a distance L1 between the front wall 51 and the rear wall 52 (the distance between the outer surfaces b) is smaller than the direction X orthogonal to the direction Y opposite to the front wall 51 and the rear wall 52. The flat shape of the distance L2 between the side walls 53, 54 is. In order to make the main body portion 5 a flat shape, the distance between the pair of side walls is longer than the distance between the front wall 51 and the rear wall 52 as long as the height position C7 of the center of the through hole 71 in the height direction of the grip portion is formed. can.

Hereinafter, the long axis direction X orthogonal to the direction in which the front wall 51 and the rear wall 52 face each other (the short axis direction) Y is also referred to as the width direction X.

Figure 2 shows the height position P from the bottom 4 to the height T of the neck portion 3 In the horizontal section of the main body portion 5, whether or not the distance L1 is smaller than the distance L2 is determined at a height position C7 of the center portion in the height direction of the through hole 71 for forming the grip portion 7.

The grip portion 7 is formed on the main body portion 5 from the shoulder portion around the neck portion 3 to the lower portion of the bottle. Further, the main body portion 5 and the grip portion 7 are connected to each other via a through hole (grip space) 71 for forming a grip portion. In order to grasp the bottle, the grip portion 7 preferably has rigidity, and when the main body portion 5 is provided with the grip portion 7, the front wall and the rear wall of the bottle container are easily deformed. That is, since the grip portion is provided, the front wall and the rear wall are easily thinned, which is related to the effect of the present creation. The lower portion of the bottle is in the range from the central portion to the bottom portion in the height direction of the main body portion 5. The container bodies of the bottle containers shown in Figs. 16(a) and 16(b) are provided with the body portion 5 from the shoulder portion to the lower portion of the bottle. The grip portion 7 is formed. Thus, in the bottle holder of the present invention, the grip portion formed from the shoulder portion to the lower portion of the bottle also includes a grip portion extending from the shoulder portion toward the lower portion of the bottle.

Regarding the grip portion 7, the inside thereof is hollow, and a part of the contents contained in the bottle container 1 also enters into the grip portion 7.

The distance L1 between the front wall 51 and the outer surface b of the rear wall 52 is preferably 80% or less, more preferably 70% or less, more preferably 70% or less, more preferably 70% or less, between the left and right side walls 53, 54. 50% or more, further preferably 60% or more. The distance L1 and the distance L2 are measured at a height position C7 at the center in the height direction of the through hole 71 for forming the grip portion 7.

In the range in which the main body portion 5 has the through hole 71 for forming the grip portion in the height direction, the resin of the other portion corresponding to the grip portion 7 (handle) having the strength is reduced, and the front wall 51 and the rear wall 52 are formed. One of the causes of the deformation is easy, and therefore it is reasonable to measure the distances L1 and L2 at the height position C7 of the center of the through hole 71 in the height direction.

When the main body portion 5 in the present embodiment is more specifically described, the front wall 51 and the rear wall 52 have the first ridge line 56 between the first side wall 53 and the first side wall 53, and the grip portion 7 is formed. The second ridge line 57 is provided at a connecting portion of the through hole (grip space) 71 and the cylindrical wall 55 penetrating the main body portion 5. As shown in FIG. 1(b), the second ridge line 57 is surrounded by the bottle container 1 The through hole (grip space) 71 extends to the lower portion of the second side wall 54 as shown in FIG. 1(c). By providing the first ridge line 56 and the second ridge line 57, deformation against the pressure reduction inside the bottle is prevented, and it becomes inconspicuous when the rear wall 52 is deformed.

Further, the main body portion 5 has a shoulder portion 50 which is extended in the horizontal direction from the lower end of the neck portion 3 at the upper portion, and is at the boundary between the front wall 51 and the shoulder portion 50 and the boundary between the rear wall 52 and the shoulder portion 50. An upper ridge line 58 is formed there. As shown in Fig. 1(b), the upper ridge line 58 extends obliquely from the first side wall 53 side toward the second side wall 54 side in the upper portion of the main body portion 5, and the first ridge line 56 continues as the upper ridge line at the upper portion of the main body portion 5. 58. Further, as shown in FIG. 1(c), the upper ridge line 58 continues over the upper portion of the front wall 51, the upper portion of the second side wall 54, and the upper portion of the rear wall 52.

Further, a step portion 59 is formed at each lower portion of the front wall 51 and the rear wall 52. Regarding the step portion 59, the respective outer surfaces b of the front wall 51 and the rear wall 52 are formed to protrude toward the outer side of the container 1 in the vicinity of the bottom portion 4. The first side wall 53 and the shoulder portion 50 are continued by a convex curved surface without being separated by a ridge line.

Regarding the front wall 51 and the rear wall 52, substantially the entire area surrounded by the first ridge line 56, the second ridge line 57, the upper ridge line 58, and the step portion 59 serves as a label bonding surface 9 for attaching the label. . In Fig. 1, the shape and the bonding position of the label attached to the label bonding surface 9 are indicated by reference numeral 10A.

In the present embodiment, as shown in FIG. 2, the label bonding surface 91 formed on the front wall 51 is curved in a convex arc shape in a horizontal cross section toward the outside of the container. The label bonding surface 92 formed on the rear wall 52 is similarly curved in a convex arc shape toward the outer side of the container in a horizontal cross section.

The radius of curvature of the horizontal cross section of the label bonding surface 9 is preferably R40 cm or more, and more preferably R100 cm, from the viewpoint of making the attachable label a large viewpoint and improving the visibility of the displayed label. the above. The upper limit is preferably 500 cm or less, and more preferably 300 cm or less. R is the radius of curvature of the horizontal section.

The larger the area S1 of the area occupied by the label relative to the labeling surface 9 of the front wall of the bottle container, the more effective the creation is. The occupancy rate (%) of the label is preferably 70 to 90%, more preferably 70 to 80%.

The occupancy ratio (%) of the label indicates the area ratio (S1/S2) of the area S1 of the label attached to the label bonding surface 9 of the front wall to the area S2 of the label bonding surface 9 in percentage.

Here, the front wall 51 and the rear wall 52 are attached to a flat bottle having a handle, and the surface of the bottle other than the grip portion includes a quadratic surface before and after (the label surface is R40 or more and R500 or less). The side profile is a quadric surface and is adjacent to the face having the handle. Moreover, when the bottle container is planarly developed, it becomes a quadratic surface (the label surface is R40 or more and R500 or less), and is adjacent to the surface having the handle.

Further, in the label bonding surface 91 of the present embodiment, the horizontal cross section is curved toward the outer side of the container, and the cross section in the height direction (vertical direction) is linear. That is, the label bonding surface 91 becomes a quadric surface. In the present specification, the term "quadratic surface" means a curved surface in which only one of the two axes orthogonal to each other is curved. Similarly, the label bonding surface 92 of the rear wall 52 is curved in a horizontal cross section toward the outer side of the container, and the cross section in the height direction (vertical direction) is linear. That is, the label bonding surface 92 also becomes a quadric surface.

In view of the fact that the general label lacking extensibility can also be attached aesthetically, it is preferred that the label bonding surfaces 91 and 92 are quadric surfaces, respectively.

Further, the first side wall 53 and the second side wall 54 are bent to a greater extent than the label bonding surfaces 91 and 92 in the horizontal cross section.

In the container 1 of the present embodiment, a groove 6 is formed in the label bonding surface 91 of the front wall 51 of the main body portion 5 in order to suppress deformation of the front wall 51 caused by the pressure reduction inside the container. The groove 6 in the present embodiment is a groove formed by recessing the outer surface b of the front wall 51 in a groove shape, and a plurality of strips are formed at intervals in the height direction of the container body 2. As shown in Fig. 1(b), each of the grooves 6 is a horizontal lateral groove extending in the horizontal direction, and a plurality of grooves 6 are formed in parallel with each other.

Regarding the groove 6, the depth d may be fixed over the entire length of the longitudinal direction, and the depth d of the groove may gradually decrease from the vicinity of the central portion in the longitudinal direction toward both ends, and further, in the depth When the end portions are gradually decreased, the bottom portion of the groove may be flush with the outer surface b of the other portions at the both end portions.

The groove 6 formed in the front wall preferably satisfies either or both of the following conditions from the viewpoint of suppressing deformation due to pressure reduction inside the container. The same applies to the inclined grooves 6A, 6B or the small grooves 61 of the intermittent grooves described below.

Regarding the groove provided as the groove 6, the depth d of the deepest portion is preferably 1 mm or more, more preferably 10 mm or less, further preferably 5 mm or less, and further preferably 1 mm or more and 10 mm or less. Further, it is preferably 1 mm or more and 5 mm or less.

Further, the width W of the groove 6 is preferably 50% or more, more preferably 100% or more, further preferably 200% or less, further preferably 160% or less, and more preferably the depth d. It is 50% or more and 200% or less, and more preferably 100% or more and 160% or less.

Further, the width W of the groove 6 is preferably 2 mm or more, more preferably 3 mm or more, further preferably 10 mm or less, further preferably 5 mm or less, further preferably 2 mm or more and 10 mm or less, and further preferably It is 3 mm or more and 5 mm or less.

Further, the length of the groove 6 is preferably 10% or more of the above-mentioned distance L2, and more preferably 20% or more. Regarding the following discontinuous grooves (6', 6A', 6B'), it is preferable that the total length of the small grooves is in this range.

The length of the groove 6 is preferably 40% to 70% of the container width L5 (refer to FIG. 2) other than the grip portion.

The container width L5 other than the grip portion is measured at a height position P which is equally divided by the height T of the bottom portion 4 to the neck portion 3.

Further, regarding the groove 6 (groove), the center portion 5 is divided into five parts in the height direction by four horizontal planes by dividing the height T from the bottom portion 4 to the neck portion 3 into five parts. At least one of the three regions may be formed.

Further, the grooves 6 (ribs) may also be concentrated in the bottom direction. For example, the horizontal groove 6 (rib) may be disposed in such a manner that it does not exist in the region from the bottom 4 to the neck The height of the portion 3 is divided into five equal parts, and the main body portion 5 is divided into the uppermost one of the five portions in the height direction by four horizontal planes.

Moreover, the groove 6 (groove) is as shown in FIG. 3, and may have a bottom surface and a cross section on the upper and lower surfaces sandwiching the bottom surface. As shown in Fig. 9(c) and Fig. 9(d), the shape of the glyph may be such that the cross section is arcuate or the cross section is V-shaped, and the deformation due to the decompression inside the container is suppressed. Preferably, the cross section is a circular arc.

Further, the total length of the grooves 6 formed in the front wall 51 is preferably 1.5 times or more, more preferably 2 times or more, the width L4 of the container.

The container width L4 is a distance L2 between the left and right side walls 53, 54 from the height position T of the bottom portion 4 to the height T of the neck portion 3.

In the present creation, the groove provided in the front wall 51 preferably extends in a direction crossing the height direction line L3 of the container body 2. The intersection with the height direction L3 means that the inclination angle θ with respect to the height direction line L3 is 20 to 90°, more preferably 45 to 90°. The height direction line L3 is a line perpendicular to the bottom portion 4 in front of the container body [refer to FIG. 1(b)]. As shown in FIGS. 5(b) and 6(b), the inclination angle θ is also in the container body. The measurement was performed in the front view.

Further, as in the groove 6 of the present embodiment, the groove provided in the front wall 51 is preferably a horizontal groove extending in the circumferential direction of the main body portion. The horizontal groove has an inclination angle θ with respect to the height direction line L3 of 90 to 60° (the inclination angle with respect to the horizontal plane is 0 to 30°). More preferably, the inclination angle θ of the horizontal groove with respect to the height direction line L3 is 90 to 70° (the inclination angle with respect to the horizontal plane is 0 to 20°). The angle of inclination of the horizontal groove shown in Fig. 1 with respect to the horizontal plane is 5 or less, more specifically 0.

In the container 1 of the present embodiment, the rear wall 52 is more easily deformed than the front wall 51, and the deformation due to the pressure reduction inside the container is concentrated on the rear wall 52 side of the main body portion 5, and thereafter. Grooves (concave ribs) such as the horizontal grooves 6 provided in the front wall 51 are not formed on the wall 52.

Further, in the main body portion 5 and the bottom portion 4 of the container 1 of the present embodiment, a horizontal groove 6 is formed in the front wall 51, and a groove such as a horizontal groove 6 is not formed in the rear wall 52, except for this aspect. In addition, it has a shape that is plane symmetrical with respect to the imaginary plane S located between the front wall 51 and the rear wall 52.

The bottle container 1 of the present embodiment is used by attaching a label to at least the label bonding surface 91 on the side of the wall 51 on the side of the horizontal groove 6 (rib). Further, it is preferable that the label bonding surface 92 on the side of the rear wall 52 also has a label attached thereto. However, the label bonding surface 92 on the side of the rear wall 52 may not be attached to the label.

The front wall 51 and the rear wall 52, in particular, the label bonding surfaces 91 and 92 are the surfaces having the largest area on the main body portion 5. From the viewpoint of visibility, etc., it is preferable to display a description of the product name or the content. The labels are attached to the faces.

Here, when the content is gas-absorptive, or when the liquid is cooled after the high-temperature liquid is injected and sealed, the internal pressure of the container is easily decompressed compared with the external atmosphere and is easily deformed.

In this respect, in the bottle container 1 of the present embodiment, since the horizontal groove 6 (concave rib) is formed in the front wall 51, the front wall 51 is less likely to be deformed by the pressure reduction inside the container. Further, since the ribs such as the horizontal grooves 6 are not formed in the rear wall 52, deformation is more likely to occur than in the front wall 51, so that deformation due to decompression inside the container is concentrated on the rear wall 52, thereby further suppressing the front wall. 51 deformation. Although the thickness of the container is thickened or the ribs are provided on both sides of the front wall and the rear wall in order to increase the rigidity, the pressure reduction inside the container is not eliminated in this case. In the present technology, the rear wall 52 is more easily deformed than the front wall 51, so that the container can maintain a stable shape even if decompression occurs inside the container.

Therefore, in the bottle container 1, on the display rack in the supermarket, the convenience store, the department store, and the like in which the contents are stored, the label attached to the wall 51 which is not easily deformed is directed toward the front side of the rack, and The wall 52 side is displayed toward the inner side of the rack, whereby the appearance seen by the customer (consumer, intended purchaser) can be kept beautiful for a long time.

Further, in the case where both the front wall 51 and the rear wall 52 of the main body portion are attached to the label, it is preferable that the label attached to the wall which is not easily deformed is set to display the label of the product name to the maximum. The label attached to the wall after being easily deformed is a sub-label indicating a component display having a low importance in design.

A shrink label can also be used for the front wall 51 and the rear wall 52 of the main body. In particular, in the case of a thin shrink label, the visibility is reduced due to wrinkles of the shrink label surface caused by deformation of the container. According to the present technology, it is possible to prevent deformation of the surface to be displayed using the shrink label.

In the bottle container 1 of the present embodiment, a lid 8 including two members of the take-out lid 80 and the metering lid 86 is attached to the neck portion 3 of the container body 2. Fig. 1(b) shows a state in which the lid 8 is removed from the neck portion 3, and in a state in which the lid 8 is attached to the neck portion 3 (in a state of being mounted), a part E thereof is entered into the main body portion of the container body. The state within 5.

The lid 8 has a dispensing cover 80 that is fitted to the mouth and neck portion 3, and a metering cover 86 that is fixed to cover the dispensing cylinder 82 (outflow port) of the dispensing lid 80. The dispensing lid 80 is provided with a dispensing cylinder 82. The outer cylinder 83 (the tubular portion 8B) is formed by providing a space between the discharge cylinder 82 and the discharge cylinder 82.

As shown in FIG. 4, the ejection cap 80 has a connecting skirt portion 81 for the container body 2, a dispensing cylinder 82, and an outer cylinder 83 surrounding the dispensing cylinder. The connecting skirt portion 81 is formed so as to hang down from the outer peripheral portion of the annular protruding portion that protrudes outward from the height direction of the outer tube 83, and the connecting skirt portion 81 is attached to the opening by a known method such as fitting or screwing. The neck 3 is fixed to the container body 2 filled with the contents.

The injection cover 80 includes a discharge cylinder 82 that protrudes upward from the partition plate 84, an outer cylinder 83 that is connected to the discharge cylinder 82 via the partition plate 84, and a concave liquid formed between the discharge cylinder 82 and the outer cylinder 83. The recovery space 85 is provided with an opening 84a for liquid recovery at the bottom of the liquid recovery space 85. Further, the discharge cylinder 82 is formed with a separation portion (outlet port notch) 82a in the axial direction from the upper end portion thereof to the opening 84a for liquid recovery. The outer cylinder 83 has a thread 83a on the outer surface, and the metering cover 86 can be detachably screwed.
