Description

Bottle container

The present invention relates to a bottle container.

Conventionally, synthetic resin bottle containers have been widely used as containers for liquid substances such as liquid detergents, liquid softeners, and liquid bleaches.
If the conventional bottle container has gas-absorbing contents, the container may be deformed due to a decrease in the pressure in the container due to a decrease in gas in the head space.
By absorbing the gas (gas) in the head space, which is the space remaining above the container, the pressure in the head space is reduced to a pressure lower than the atmospheric pressure, thereby causing an unintended dent or deformation in the container. In particular, the spout is fitted to the mouth part, and the spout is a spout container having a shape that swells in the vicinity of the fitting part or the fitting part, and the container body part has a wide shape in the shoulder part or in the vicinity of the shoulder part. In this case, the amount of gas absorbed in the head space is large.
When such a dent or the like is generated in a container of a commodity displayed at a store, the image of the commodity is also deteriorated. This problem may occur not only when the contents are gas-absorbing but also when the liquid is cooled after being injected and sealed with a hot liquid.

By changing the curvature of the front side and the back side of the horizontal section of the barrel, the problem of deformation caused by the pressure reduction of the internal pressure of the bottle container is intentionally provided by the side surface that is deformed corresponding to the pressure reduction. A technique to be solved has been proposed (Patent Document 1).
In addition, a recess guide wire is provided on at least one of the front and back side walls of the body of the bottle container, and the body is gradually reduced in diameter from the bottom and the shoulder toward the recess guide wire. By doing this, a technique has been proposed in which a part to be deformed is specified and a decrease in appearance is minimized (Patent Document 2).

JP 2001-199419 A JP 2009-132436 A JP 2002-362525 A

In the technique of Patent Document 1, since it is essential to change the curvature on the front surface side and the curvature on the back surface side, the shape of the container is restricted, such as being not applicable to a container whose shape is symmetrical between the front surface side and the back surface side. The Patent Document 1 describes that a horizontal band-shaped rib is provided, but the horizontal band-shaped rib is provided on the back side where the curvature is small and easily deformed.
In the technique of Patent Document 2, when a label is applied so as to cover the dent guide line, the label is deformed at the position of the dent guide line. On the other hand, if the label is applied while avoiding the dent guide line, the label is applied. The possible range is limited. Moreover, the dent guide line of Patent Document 2 is not a concave rib.

Patent Document 3 discloses a technique for providing ribs on a squeeze container. However, the rib is provided in order to increase the breaking strength of the container, and is formed on a pair of opposing surfaces in the body of the container.

It has. The container main body 2 has the mouth part 3 upward and the bottom part 4 downward. The mouth neck 3 has an opening at the upper end.
The mouth neck 3 has a cylindrical shape, and has an opening 31 at the upper end. The mouth part 3 is attached with a cap and can seal the inside of the container body 2. The configuration of the cap mounted on the mouth neck 3 is not particularly limited. For example, as shown in FIG. 1, a pouring cap 80 having a pouring cylinder 82 and a metering screwed onto the pouring cap 80 are provided. The thing consisting of the cap 86 etc. are mentioned. The bottom part 4 is formed so that the bottle container 1 can stand on a horizontal plane.
In this specification, the upper direction is a direction toward the upper side in the vertical direction when the bottle container is self-supported with the bottom of the container body placed on a horizontal plane, and the lower side is the bottle container and the bottom of the container body is horizontal. It is the direction which goes to the downward direction of the vertical direction when it is installed in and self-supported.

The trunk portion 5 is located between the mouth portion 3 and the bottom portion 4 in the height direction of the container body 2. As shown in FIG. 2, the body portion 5 has a flat shape with a horizontal section having a major axis direction X and a minor axis direction Y. The body part 5 is located at both ends in the major axis direction X, the shoulder part 50 shaped to expand while horizontally expanding from the lower end of the neck part 3, the front wall 51 and the rear wall 52 facing the inner surfaces a. A grip portion having a pair of side walls (first side wall 53 and second side wall 54) and formed on the second side wall 54 (one side wall) side in the long axis direction X so as to extend from the shoulder portion 50 to the lower portion of the bottle. 7. A horizontal groove 6 (concave rib) made of 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 body portion 5.
The boundary surfaces of the front wall 51, the rear wall 52, the first side wall 53, and the second side wall 54 may be connected smoothly or through a boundary surface having a large curvature. Moreover, you may connect via the

ridgelines

56 and 57 as shown in FIG.
As described above, the container 1 according to the present embodiment is formed with the grip portion 7 for holding the container and holding the container. The body portion 5 has a through-hole (grip) for forming the grip portion 7. Space) 71 is formed. A through hole (gripping space) 71 for forming the grip portion 7 is formed by connecting the front wall 51 and the rear wall 52 with a cylindrical wall 55 penetrating the trunk portion 5.

As shown in FIG. 2, the body portion 5 has a direction X in which a distance L1 between the front wall 51 and the rear wall 52 (a distance between the outer surfaces b) is orthogonal to a direction Y in which the front wall 51 and the rear wall 52 face each other. It has a flat shape smaller than the distance L2 between the left and

right side walls

53, 54. In order for the trunk | drum 5 to be said to be flat shape, in the height position C7 of the height direction center of the through-hole 71 for gripping part formation, from a distance between the front wall 51 and the rear wall 52, between a pair of side walls Long distance is good.
Hereinafter, the major axis direction X perpendicular to the direction (minor axis direction) Y in which the front wall 51 and the rear wall 52 face each other is also referred to as the width direction X.
FIG. 2 shows a horizontal section of the body 5 at a height position P that bisects the height T from the bottom 4 to the mouth 3, but whether or not the distance L 1 is smaller than the distance L 2. Is determined at the height position C7 of the central portion in the height direction of the through hole 71 for forming the grip portion 7.

The grip portion 7 is formed on the body portion 5 from the shoulder portion around the mouth neck portion 3 to the lower portion of the bottle. Moreover, the trunk | drum 5 and the holding part 7 are connected on both sides of the through-hole (gripping space) 71 for gripping part formation. The gripping part 7 is preferably rigid so that the bottle can be gripped, and the body part 5 is provided with the gripping part 7, which makes it easy to deform the front wall and the rear wall of the bottle container. There is. That is, since the grip portion is provided, the front wall and the rear wall are likely to be thin, which leads to the effect of the present invention. The lower part of the bottle is a range from the center part to the bottom part in the height direction of the body part 5, and the container main body of the bottle container shown in FIGS. 16 (a) and 16 (b) is both in the body part 5. A gripping portion 7 is provided so as to extend from the shoulder portion to the lower portion of the bottle. Thus, the “gripping part formed so as to extend from the shoulder part to the lower part of the bottle” in the bottle container of the present invention includes a gripping part extending from the shoulder part toward the lower part of the bottle.

In the range having the through hole 71 for forming the grip part in the height direction of the body part 5, the resin in other parts is reduced by the amount of forming the grip part 7 (handle) having strength, which is the front wall 51. In addition, since the rear wall 52 is likely to be deformed, it is reasonable to measure the distances L1 and L2 at the height position C7 in the center of the through hole 71 in the height direction.

The trunk portion 5 in the present embodiment will be described more specifically. The front wall 51 and the rear wall 52 each have a first ridge line 56 between the first side wall 53 and the grip portion. 7 has a second ridge line 57 at a connecting portion with a cylindrical wall 55 that penetrates the body portion 5 and forms a through-hole (gripping space) 71 for forming 7. The second ridge line 57 surrounds the through-hole (gripping space) 71 in the front view of the bottle container 1 as shown in FIG. 1 (b), and the second side wall as shown in FIG. 1 (c). 54 extends below. By providing the first ridge line 56 and the second ridge line 57, it is possible to prevent the bottle inner pressure from being deformed and to be less noticeable when the rear wall 52 is deformed.
Moreover, the trunk | drum 5 has the shoulder part 50 which descends, expanding in the horizontal direction from the lower end of the neck part 3 in the upper part, the boundary of the front wall 51 and the shoulder part 50, and the rear wall 52 and the shoulder part 50. An upper ridge 58 is formed at the boundary. As shown in FIG. 1B, the upper ridge line 58 extends obliquely from the first side wall 53 side to the second side wall 54 side in the upper part of the body part 5, and the first ridge line 56 is formed of the body part. 5 is continuous with the upper ridge line 58. Moreover, the upper ridge line 58 is continuous over the upper part of the front wall 51, the upper part of the 2nd side wall 54, and the upper part of the rear wall 52, as shown in FIG.1 (c).
Further, step portions 59 are formed at the lower portions of the front wall 51 and the rear wall 52. The step portion 59 is formed such that the outer surface b of each of the front wall 51 and the rear wall 52 projects outward from the container 1 in the vicinity of the bottom portion 4. The 1st side wall 53 and the shoulder part 50 are continuing on the convex curved surface, without pinching a ridgeline.

Each of the front wall 51 and the rear wall 52 has a label attachment surface on which a label is attached over substantially the entire area surrounded by the first ridge line 56, the second ridge line 57, the upper ridge line 58, and the stepped portion 59, respectively. Nine. In FIG. 1, the shape of the label stuck on the label sticking surface 9 and the sticking position are indicated by reference numeral 10A.

In the present embodiment, as shown in FIG. 2, the label attaching surface 91 formed on the front wall 51 has a horizontal cross section curved in a convex arc shape toward the outside of the container. Similarly, the label attaching surface 92 formed on the rear wall 52 has a horizontal section curved in a convex arc shape toward the outside of the container.
The radius of curvature in the horizontal section of the label attaching surface 9 is preferably R40 cm or more, more preferably R100 cm or more, from the viewpoint of increasing the size of the label that can be attached and the visibility of the attached label display. is there. The upper limit is preferably 500 cm or less, more preferably 300 cm or less. R is the radius of curvature of the horizontal section.

The present invention is more effective as the area S1 occupied by the label is larger than the area S2 of the label attaching surface 9 on the front wall of the bottle container. The label occupancy (%) is preferably 70 to 90%, and more preferably 70 to 80%.
The label occupancy (%) is expressed as a percentage of the area ratio (S1 / S2) of the area S1 of the label attached to the label attaching surface 9 on the front wall to the area S2 of the label attaching surface 9. Is.

Here, in the flat bottle with a handle, the front wall 51 and the rear wall 52 are formed on the surface of the bottle excluding the grip portion on the cross-section formed by the front and rear secondary curved surfaces (label surface R40 to R500) and side surfaces. The surface is a next curved surface and is adjacent to the surface having the handle. Further, when the bottle container is flattened, it becomes a secondary curved surface (label surface R40 or more and R500 or less) and is a surface adjacent to the surface having the handle.

Further, the label attaching surface 91 in the present embodiment is curved convexly toward the outside of the container with respect to the horizontal cross section, while the cross section in the height direction (vertical direction) is linear. Yes. That is, the label attaching surface 91 is a quadric surface. The “secondary curved surface” in this specification is a curved surface in which only one of two axes orthogonal to each other is curved. Similarly, with respect to the label attaching surface 92 of the rear wall 52, the horizontal cross section is curved convexly toward the outside of the container, while the cross section in the height direction (vertical direction) is linear. There is no. That is, the label attaching surface 92 is also a secondary curved surface.
The label attachment surfaces 91 and 92 are preferably quadric surfaces, respectively, from the viewpoint that a general label with poor extensibility can be attached cleanly.

In addition, the 1st side wall 53 and the 2nd side wall 54 have a large degree of curve compared with the label sticking surfaces 91 and 92 in a horizontal cross section.

In the container 1 of the present embodiment, the concave groove 6 is formed in the label attaching surface 91 of the front wall 51 of the trunk portion 5 in order to suppress the deformation of the front wall 51 due to the reduced pressure inside the container. The concave groove 6 in the present embodiment is a concave groove formed by denting the outer surface b of the front wall 51 into a groove shape, and a plurality of the concave grooves 6 are formed at intervals in the height direction of the container body 2. As shown in FIG. 1B, each of the concave grooves 6 is a horizontal horizontal groove extending in the horizontal direction, and the plurality of concave grooves 6 are formed in parallel to each other.
The depth d of the concave groove 6 may be constant over the entire length in the longitudinal direction, or the depth d of the groove may gradually decrease from the vicinity of the central portion in the longitudinal direction toward both ends. When the depth gradually decreases toward both end portions, the bottom portion of the groove may be flush with the outer surface b of the other portion at both end portions.

From the viewpoint of suppressing deformation due to reduced pressure inside the container, the concave groove 6 formed on the front wall preferably satisfies one or more of the following conditions. The same applies to the

inclined grooves

6A and 6B described later and the small grooves 61 of intermittent grooves.
The depth d of the deepest portion of the concave groove provided as the concave groove 6 is preferably 1 mm or more, preferably 10 mm or less, more preferably 5 mm or less, and preferably 1 mm or more and 10 mm. Hereinafter, it is more preferably 1 mm or more and 5 mm or less.
Further, the width W of the concave groove 6 is preferably 50% or more, more preferably 100% or more, preferably 200% or less, more preferably 160% or less, with respect to the depth d. Further, it is preferably 50% or more and 200% or less, 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, preferably 10 mm or less, more preferably 5 mm or less, and preferably 2 mm or more and 10 mm or less, more preferably. It is 3 mm or more and 5 mm or less.
The length of the concave groove 6 is preferably 10% or more, more preferably 20% or more of the distance L2. The intermittent concave grooves (6 ′, 6A ′, 6B ′) described later preferably have a total length of the small concave grooves within this range.
The length of the concave groove 6 is preferably 40% to 70% of the container width L5 (see FIG. 2) excluding the grip portion.
The container width L5 excluding the gripping part is measured at a height position P that divides the height T from the bottom part 4 to the mouth part 3 into two equal parts.
Further, the concave groove 6 (concave groove) is formed at the center when the body part 5 is divided into five in the height direction by four horizontal planes so that the height T from the bottom part 4 to the mouth part 3 is equally divided into five parts. At least one can be formed in the three regions.
Furthermore, the concave grooves 6 (ribs) can be concentrated in the bottom direction. For example, the horizontal groove 6 (rib) is the uppermost portion when the body portion 5 is divided into five in the height direction by four horizontal planes so that the height T from the bottom portion 4 to the mouth neck portion 3 is equally divided into five. It can be located so that it does not exist in one area.

In addition, as shown in FIG. 3, the concave groove 6 (concave groove) may have a U-shaped cross section having a bottom surface and upper and lower surfaces positioned above and below the bottom surface. ) And FIG. 9 (d), the cross section may be arcuate, or the cross section may be V-shaped. However, from the viewpoint of suppressing deformation due to decompression inside the container, the cross section is arcuate. Those are preferred.

Further, the total length of the concave grooves 6 formed in the front wall 51 is preferably 1.5 times or more, more preferably 2 times or more of the container width L4.
The container width L4 is a distance L2 between the left and

right side walls

53, 54 at a height position P that bisects the height T from the bottom 4 to the mouth neck 3.

In the present invention, the concave groove provided in the front wall 51 preferably extends in a direction intersecting 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 straight line perpendicular to the bottom 4 in the front view of the container body (see FIG. 1B), and the inclination angle θ is also as shown in FIGS. 5B and 6B. Further, it is measured in a front view of the container body.

Further, it is more preferable that the concave groove provided in the front wall 51 is a horizontal concave groove extending in the circumferential direction of the trunk portion like the concave groove 6 of the present embodiment. The horizontal groove has an inclination angle θ with respect to the height direction line L3 of 90 to 60 ° (an inclination angle with respect to a horizontal plane is 0 to 30 °). It is more preferable that the horizontal groove has an inclination angle θ with respect to the height direction line L3 of 90 to 70 ° (inclination angle with respect to the horizontal plane is 0 to 20 °). The horizontal groove shown in FIG. 1 has an inclination angle with respect to a horizontal plane of 5 ° or less, more specifically 0 °.

In the container 1 of the present embodiment, the rear wall 52 is assumed to be easily deformed as compared to the front wall 51, and in order to concentrate the deformation due to the reduced pressure inside the container on the rear wall 52 side of the trunk portion 5, No groove 52 (concave rib) such as the horizontal groove 6 provided in the front wall 51 is formed in 52.
The body 5 and the bottom 4 of the container 1 of the present embodiment have a horizontal groove 6 formed in the front wall 51, whereas a groove such as the horizontal groove 6 is formed in the rear wall 52. Except for this point, it has a plane-symmetric shape with respect to the virtual 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 attaching surface 91 on the front wall 51 side where the horizontal concave grooves 6 (ribs) are formed. Moreover, it is preferable that a label is stuck also on the label sticking surface 92 on the rear wall 52 side. However, the label does not have to be attached to the label attaching surface 92 on the rear wall 52 side.
The front wall 51 and the rear wall 52, in particular, the label sticking surfaces 91 and 92 are the surfaces having the largest area in the trunk portion 5, and the labels on which the product name, description of contents, etc. are displayed are on these surfaces. Adhering is preferable from the viewpoint of visibility.
Here, when the contents are gas-absorbing, or when the liquid is cooled after injecting and sealing a high-temperature liquid, the internal pressure of the container is reduced more than the outside air, and deformation tends to occur.
In this regard, the bottle container 1 of the present embodiment has the horizontal grooves 6 (concave ribs) formed in the front wall 51, so that the front wall 51 is unlikely to be deformed due to the decompression inside the container. In addition, since the rear wall 52 is not formed with ribs such as the horizontal grooves 6 and is more likely to be deformed than the front wall 51, deformation due to decompression inside the container is concentrated on the rear wall 52, Thereby, the deformation of the front wall 51 is further suppressed. In order to improve the rigidity, there are cases where the container is made thicker or convex ribs are provided on both the front wall and the rear wall. In this case, the decompression inside the container is not eliminated. In the present technology, since the rear wall 52 is more easily deformed than the front wall 51, the container can maintain a stable form even if the inside of the container is decompressed.
Therefore, the label attached to the front wall 51 which is hard to be deformed on a display shelf in a store such as a supermarket, a convenience store, a department store or the like containing the contents in the bottle container 1 is placed on the front side of the shelf and the rear wall 52 side on the shelf. By displaying toward the back side, the appearance that can be seen by the customers (consumers, prospective purchasers) can be kept clean for a long period of time.

In addition, when sticking a label on both the front wall 51 and the rear wall 52 of a trunk | drum, the label stuck on the front wall which is hard to deform | transform is made into the label by which the brand name was displayed most, and is easy to deform | transform. The label attached to the wall is preferably a sub-label on which a component display having a low design importance is described.

Shrink labels can also be used for the front wall 51 and the rear wall 52 of the trunk. In particular, in the case of a thin shrink label, wrinkles on the shrink label surface due to deformation of the container are generated, and display properties are deteriorated. According to the present technology, it is possible to prevent deformation of a surface to be displayed using a shrink label.

In the bottle container 1 of the present embodiment, a cap 8 composed of two members, a pouring cap 80 and a measuring cap 86, is attached to the mouth neck 3 of the container body 2. FIG. 1B shows a state in which the cap 8 is removed from the mouth neck portion 3, but when the cap 8 is attached to the mouth neck portion 3 (attached state), a part E of the cap 8 is shown. Then, the container body 5 enters the body 5.
The cap 8 includes a pouring cap 80 fitted to the neck 3, and a measuring cap 86 fixed so as to cover the pouring cylinder 82 (spout) of the pouring cap 80. 80 includes an extraction cylinder 82 and an outer cylinder 83 formed with a space between the extraction cylinder 82.
As shown in FIG. 4, the dispensing cap 80 includes a connection skirt portion 81 for the container body 2, a dispensing cylinder 82, and an outer cylinder 83 that surrounds the dispensing cylinder. The connection skirt portion 81 is formed so as to hang from the outer peripheral portion of the annular projecting portion projecting outward from the middle of the outer cylinder 83 in the height direction, and the connection skirt portion 81 is fitted, screwed, etc. It is fixed to the container main body 2 filled with the contents by attaching to the neck part 3 by the known method.
The pouring cap 80 includes a pouring cylinder 82 projecting upward from the partition plate 84 and an outer cylinder 83 coupled to the pouring cylinder 82 via the partition plate 84, and the pouring cylinder 82, the outer cylinder 83, A concave liquid recovery space 85 is formed therebetween, and a liquid recovery opening 84 a is provided at the bottom of the liquid recovery space 85. Further, the dispensing cylinder 82 is formed with an axial cut-out portion (pour-out notch) 82a that reaches the liquid recovery opening 84a from its upper end. The outer cylinder 83 has a thread 83a on the outer surface, and is capable of being screwed into the measuring cap 86 in a detachable manner.
