Summary of the Invention

Problem to be Solved by the Invention

[0004] In recent years, resource saving and weight reduction have been required for resin containers, and thinner resin containers with reduced material usage are widely used. However, thinned resin containers are relatively poor in strength. After filling with liquid contents, the internal gas expands and contracts as the outside temperature rises and falls, resulting in pressure increase and pressure reduction, which may deform the outer shape. The resin container of Patent Document 1 is described as providing good aesthetics by a plurality of cut surfaces, but no mention is made of resource saving or weight reduction.

[0005] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a resin container that can achieve good aesthetics while realizing resource saving and weight reduction.

Means for Solving the Problem

[0006] In order to achieve the above object, the resin container according to the present invention is characterized by the following [1] to [7].

The inclined ribs provided on the two panels are inclined in the same direction. Plastic container.

[0007] In the resin container with the configuration described in [1] above, a panel without inclined ribs is provided between two panels with inclined ribs, and the inclined ribs on the two panels are inclined in the same direction. This provides good aesthetics as well as sufficient strength. Therefore, with the resin container with the configuration described in [1] above, sufficient strength can be obtained without increasing the thickness of the body, so even if the internal gas expands and contracts due to changes in ambient temperature, causing pressure to rise and fall, the possibility of deformation of the external shape is low, thus achieving resource conservation and weight reduction.

[0008] [2] In the resin container described in [1] above, A pair of first panels facing each other in the longitudinal direction of the resin container, A pair of second panels facing each other in the short direction of the resin container, A third panel provided between the first panel and the second panel, The inclined ribs are provided on the third panel.

Plastic container.

[0015] According to the resin container described in [5] above, the first panel has a first curved surface and a second curved surface. As a result, the central part in the height direction becomes the most concave arc surface, thereby achieving both strength and good aesthetics.

[0016] [6] In the resin container described in [2] above, In the pair of said first panel and said third panel, a pair of edges opposed in the height direction are provided protruding toward a side away from each other, A resin container.

[0017] According to the resin container of the above [6], the first panel naturally continues to the arc surface of the shoulder portion and the arc surface of the bottom portion, whereby good aesthetic properties can also be obtained.

[0018] [7] In the resin container according to the above [4], The edge to which the first label (label) can be adhered: a pair of first side portions opposed in the height direction are provided protruding toward a side away from each other, and a pair of second side portions opposed in the circumferential direction are provided protruding toward a side approaching each other, A resin container.

[0019] According to the resin container of the above [7], the first side portions act as ribs with respect to the arc surface of the shoulder portion and the arc surface of the bottom portion, whereby strength can also be secured. Effects of the Invention

[0023] Hereinafter, a resin container according to an embodiment of the present invention will be described with reference to the drawings. For the sake of convenience in the description below, the "height direction," "longitudinal direction," and "short direction" will be defined as shown in Figure 1 and subsequent figures. The "height direction," "longitudinal direction," and "short direction" are orthogonal to each other. The "height direction" is the same direction as the insertion direction of the opening of the container body of the resin container according to the embodiment. The "longitudinal direction" is the longer direction of the container body when viewed along the "height direction." The "short direction" is the shorter direction of the container body when viewed along the "height direction." Furthermore, one side in the "short direction" will be referred to as the "front side" and the other as the "back side," and one side in the "longitudinal direction" will be referred to as the "right side" and the other as the "left side." The above expressions are added for convenience in explaining the embodiments and are not essential to the invention.

[0024] <Overview of the resin container 10> As shown in Figure 1, the resin container 10 comprises a container body 15 having a mouth portion 11, a shoulder portion 12, a body portion 13, and a bottom portion 14. The cross-sectional shape (longitudinal direction) of the body portion 13 is elongated. The longitudinal cross-sectional shape (short direction) of the body portion 13 is short. The mouth portion 11 is substantially cylindrical in shape and communicates with the inside of the container body 15. The mouth portion 11 has a spiral male screw portion 11A formed along its outer circumference. The container body 15 can be sealed by screwing a screw cap (not shown) onto the mouth portion 11.

[0025] The shoulder portion 12 has a convex arcuate surface 12A that is continuous with the lower end of the mouth portion 11. The body portion 13 has a roughly flattened octagonal cylindrical cross-section that is continuous with the shoulder portion 12. The bottom portion 14 has a convex arcuate surface 14A that is continuous with the body portion 13, and a bottom plate 14B that is continuous with the lower end of the arcuate surface 14A. Such a resin container 10 is molded from a material such as PET (polyethylene terephthalate) by, for example, blow molding, in order to be filled with liquid contents such as mouthwash or liquid detergent and sold.

[0026] <Body part 13> Figure 2 is a cross-sectional perspective view of the container body 15 cut along its longitudinal and transverse directions. As shown in Figure 2, the body portion 13 is continuous with the shoulder portion 12 and has a pair of first panels 20, 21, a pair of second panels 30, 31, and four third panels 40-43 that are arranged in the circumferential direction (circumferential direction centered on a line along the height direction) of the body portion 13. The first panels 20, 21 face each other along the longitudinal direction of the container body 15. The second panels 30, 31 face each other along the transverse direction of the container body 15. The third panels 40-43 are provided between the first panels 20, 21 and the second panels 30, 31. The body portion 13, with its first panels 20, 21, second panels 30, 31, and third panels 40-43, has a roughly flattened octagonal cylindrical cross-section.

[0027] <Panel 1, 20, 21> Figure 3 is a cross-sectional perspective view of the container body 15 cut along the height and longitudinal directions. As shown in Figure 3, the first panels 20 and 21 have first curved surfaces 20A and 21A and second curved surfaces 20B and 21B, respectively. The first curved surfaces 20A and 21A are concave arc surfaces that approach each other along the longitudinal direction of the container body 15 as they move from the end on the mouth 11 side in the height direction toward the bottom 14. The second curved surfaces 20B and 21B are provided on the bottom side of the first curved surfaces 20A and 21A. The second curved surfaces 20B and 21B are concave arc surfaces that approach each other along the longitudinal direction of the container body 15 as they move from the end on the bottom 14 side in the height direction toward the mouth 11.

[0028] In each figure, including Figure 3, a boundary line is shown between the first curved surfaces 20A, 21A and the second curved surfaces 20B, 21B. This boundary line is shown for the purpose of facilitating understanding. In reality, no boundary line appears between the first curved surfaces 20A, 21A and the second curved surfaces 20B, 21B; the first curved surfaces 20A, 21A and the second curved surfaces 20B, 21B are smoothly continuous.

[0029] As shown in Figure 4, the first panel 20 has a pair of opposing edges 20C, 20C along the height direction, which are convex toward the sides that are separated from each other. In other words, the plan view shape of the first panel 20 is roughly strip-shaped, and the longitudinal edges 20C, 20C are arc-shaped edges that protrude toward the sides that are separated from each other. Although Figure 4 shows only the first panel 20, the first panel 21 is similar to the first panel 20 in that a pair of opposing edges along the height direction are convex toward the sides that are separated from each other.

[0030] <Panel 2, 30> As shown in Figure 5, the second panel 30 has a pair of opposing edges 30C, 30C along the height direction, which are convex toward the sides that are separated from each other. The second panel 30 also has a pair of opposing edges 30D, 30D along the longitudinal direction, which are convex toward the sides that are separated from each other. In other words, the plan view shape of the second panel 30 is roughly strip-shaped, and the longitudinal edges 30C, 30C are arc-shaped edges that protrude toward the sides that are separated from each other.

[0031] <Panel 2, 31> As shown in Figure 6, the second panel 31 has the same shape as the second panel 30, and its longitudinal edges 31C, 31C are arc-shaped edges that protrude away from each other. That is, the second panel 31 has a pair of opposing edges 31C, 31C along the height direction, which are convex toward the side away from each other. The second panel 31 has a pair of opposing edges 31D, 31D along the circumferential direction of the container body 15, which are convex toward the side approaching each other. The resin container 10 is provided such that when the longitudinal length dimension W1 of the container body 15 is set to 1, the longitudinal length dimension W2 of the second panels 30, 31 is 1 / 2 or more. In this embodiment, when the container body 15 is cut at the position where the length dimension W1 is smallest in the center of the height direction, the length dimension W1 on the cut surface is set to 1, the length dimension W2 is provided such that it is 1 / 2 or more, but this is not the only embodiment. When the container body 15 is cut from the top end to the bottom end in the height direction, it is sufficient that at least one location on the cut surface satisfies the condition that when the length dimension W1 is set to 1, the length dimension W2 is 1 / 2 or more.

[0032] <Recessed 32, 33> Furthermore, as shown in Figures 5 and 6, the second panels 30 and 31 are provided with recesses 32 and 33, respectively, which are similar in shape to the plan view contour shape. As shown in Figure 5, the recess 32 has a pair of opposing first sides 32C, 32C along the height direction, which are convex toward the sides that are separated from each other. The recess 32 has a pair of opposing second sides 32D, 32D along the circumferential direction of the container body 15, which are convex toward the sides that are brought closer to each other. As shown in Figure 6, the recess 33 has a pair of opposing first sides 33C, 33C along the height direction, which are convex toward the sides that are separated from each other. The recess 33 has a pair of opposing second sides 33D, 33D along the circumferential direction of the container body 15, which are convex toward the sides that are brought closer to each other. As shown in Figures 5 and 6, the recesses 32 and 33 of these second panels 30 and 31 are flat surfaces, and the edges 30E, 31E of the recesses 32 and 33 are also flat surfaces.

[0033] <First label 51, second label 52> As shown in Figures 1 and 5, the second panel 30 has a first label 51 attached to its periphery 30E. The first label 51 is pre-applied for sales promotion purposes, assuming that the product, with the liquid contents filled in the resin container 10, will be displayed on the shelves of retail stores. The first label 51 uses a low-tack material that can be easily peeled off by the purchaser after purchase. As shown in Figures 1 and 6, the second panel 31 has a second label 52 attached to its recess 33. The second label 52 contains information such as the manufacturer's name, sales company name, address, contact information, URL, ingredients, capacity, intended use, instructions for use, precautions for use, barcode, and material of the container body 15 of the resin container 10, and uses an adhesive that does not easily peel off. The second label 52 is attached in a way that prevents it from easily peeling off during distribution, but it is not impossible to peel off. Users can also peel off the second label 52 to expose the design section 34 and use it.

[0034] <Design Department 34> As shown in Figures 5 and 6, the second panels 30 and 31 are each provided with a recessed design section 34 formed in an elongated shape along the height direction. In this embodiment, the design section 34 is exemplified as having seven letters "O" engraved on it, but this is merely an example, and other patterns or designs may also be used. As shown in Figure 7, the design section 34 is provided with a depth dimension D1 of 0.5 mm or more from the surface of the recess 33.

[0035] <Panel 3, pages 40-43> Figure 8 shows the third panel 40. In this embodiment, there are four third panels 40 to 43, but only the third panel 40 will be described, and the descriptions of the remaining third panels 41 to 43 will be omitted. The third panel 40 has a pair of opposing edges 40C, 40C along the height direction, which are convex toward the sides that are separated from each other. In other words, the plan view shape of the third panel 40 is roughly strip-shaped, and the longitudinal edges 40C, 40C are arc-shaped edges that protrude toward the sides that are separated from each other.

[0036] <Inclined ribs 40E, 40F> The third panel 40 is provided with inclined ribs 40E and 40F that slope upward to the right in the same direction with respect to the height. The inclined ribs 40E and 40F are ridges provided between the panel surfaces 60, 61, and 62 that make up the third panel 40. The third panels 41 to 43 are also provided with inclined ribs 41E, 41F, 42E, 42F, 43E, and 43F, respectively, as ridges between the panel surfaces 60, 61, and 62.

[0037] As shown in Figure 9, the panel surface 60 above the height of the third panel 40 is an arcuate surface with a substantially constant radius. As shown in Figure 10, the radius of the panel surface 60 below the position shown in Figure 9 is decreasing. The adjacent panel surface 61, with the inclined rib 40E as its ridge, has a larger arcuate surface radius than panel surface 60, and its arc center is also in a different position. As shown in Figure 11, the radius of the panel surface 61 below the position shown in Figure 10 is increasing. The relationship between panel surfaces 61 and 62 below the position shown in Figure 11 is the same as the relationship between panel surfaces 60 and 61 described above.

[0038] As shown in Figure 12, when a viewer looks at the third panel 41 through the third panel 40 (see arrow A in Figure 12), as shown in Figure 13, the inclined ribs 40E and 40F of the third panel 40 and the inclined ribs 41E and 41F of the third panel 41 overlap, making it appear as if the inclined ribs 40E, 41E and 40F, 41F are in an X shape, resulting in good aesthetics.

[0039] Furthermore, when a viewer looks at the third panel 43 through the third panel 40 (see arrow B in Figure 12), as shown in Figure 14, the inclined ribs 40E and 40F of the third panel 40 and the inclined ribs 43E and 43F of the third panel 43 overlap, making it appear as if the inclined ribs 40E, 43E and 40F, 43F are in an X shape, resulting in good aesthetics.

[0040] Furthermore, when a viewer looks at the third panel 42, which is located diagonally across the axis along the height direction, through the third panel 40 (see arrow C in Figure 12), as shown in Figure 15, the inclined ribs 40E and 40F of the third panel 40 and the inclined ribs 43E and 43F of the third panel 43 overlap, making it appear as if the inclined ribs 40E, 43E and 40F, 43F form an X shape, resulting in good aesthetics.

[0041] <Function of the resin container 10> If the liquid contents of the resin container 10 are translucent, the above-mentioned good aesthetics can be obtained even when the container body 15 is fully filled with liquid contents, i.e., when it is displayed in a store, which has the effect of increasing the purchase intent of buyers. Furthermore, the above-mentioned good aesthetics can be obtained when the resin container 10 is viewed from the front, from the side, and at an angle between the front and side of the container body 15, thus good aesthetics can be obtained around the entire surface of the resin container 10.

[0042] Furthermore, since the resin container 10 has first panels 20 and 21 each having first curved surfaces 20A and 21A and second curved surfaces 20B and 21B, good gripping performance can be obtained regardless of the user's hand size, grip strength, or gripping position. In addition, since the resin container 10 has third panels 40 to 43 each having inclined ribs 40E, 40F, 41E, 41F, 42E, 42F, 43E, and 43F, good gripping performance can be obtained regardless of the user's hand size, grip strength, or gripping position.

[0043] <Effects of the Embodiment> As described above, according to the resin container 10 according to the embodiment of the present invention, of the eight panels consisting of first panels 20, 21, second panels 30, 31, and third panels 40 to 43, four of the third panels 40 to 43 are provided with inclined ribs 40E, 40F, 41E, 41F, 42E, 42F, 43E, and 43F that are inclined with respect to the height direction. Furthermore, the four third panels 40 to 43 are provided between the first panels 20, 21 and the second panels 30, 31. In addition, the inclined ribs 40E, 40F, 41E, 41F, 42E, 42F, 43E, and 43F are inclined in the same direction. As a result, good aesthetics are obtained by the inclined ribs 40E, 40F, 41E, 41F, 42E, 42F, 43E, and 43F, as well as sufficient strength. Therefore, according to the resin container 10 of the embodiment of the present invention, sufficient strength can be obtained without increasing the wall thickness of at least the body portion 13. As a result, even if the gas inside expands and contracts due to changes in ambient temperature, causing the pressure to rise and fall, the possibility of deformation of the external shape is low, thus enabling resource conservation and weight reduction.

[0044] Furthermore, according to the resin container 10 of the embodiment of the present invention, it includes first panels 20, 21, second panels 30, 31, and third panels 40-43, and inclined ribs 40E, 40F, 41E, 41F, 42E, 42F, 43E, 43F are provided on the third panels 40-43. As a result, the third panels 40-43 are positioned diagonally with respect to a line along the height direction of the container body 15, thereby providing good aesthetics when viewed from the front, side, and oblique angles.

[0045] Furthermore, according to the resin container 10 of the embodiment of the present invention, when the length dimension W1 along the longitudinal direction of the container body 15 is set to 1, the length dimension W2 of the second panels 30 and 31 along the longitudinal direction is set to 1 / 2 or more. As a result, the application area of ​​the first label 51 and the second label 52 is increased, and the third panels 40 and 43 are always visible from the front, thereby also achieving good aesthetics.

[0046] Furthermore, according to the resin container 10 according to the embodiment of the present invention, the second panel 30 is provided with a recess 32 in the center, which is recessed inward while leaving a peripheral portion (edge ​​portion) 30E to which the first label 51 can be attached. As a result, the central part of the first label 51 is separated from the recess 32. Therefore, according to the resin container 10 according to the embodiment of the present invention, the purchaser can easily peel off the first label 51 after purchase, and there is no risk of the design portion 34 provided in the recess 32 of the second panel 30 being soiled and its aesthetic appeal being impaired.

[0047] Furthermore, according to the resin container 10 of the embodiment of the present invention, the first panels 20 and 21 have first curved surfaces 20A and 21A and second curved surfaces 20B and 21B. As a result, the central part in the height direction becomes the most concave arc surface, thereby achieving both strength and good aesthetics.

[0048] Furthermore, according to the resin container 10 according to an embodiment of the present invention, the first panels 20 and 21 have a pair of edges 20C, 20C and 21C, 21C that are opposite each other in the height direction, and these edges are convex toward the sides that are separated from each other. Similarly, the third panels 40 to 43 have a pair of edges 40C, 40C, 41C, 41C, 42C, 42C and 43C, 43C that are opposite each other in the height direction, and these edges are convex toward the sides that are separated from each other. As a result, the curved surface 12A of the shoulder portion 12 and the curved surface 14A of the bottom portion 14 are naturally continuous, and good aesthetics can be obtained by this as well.

[0049] Furthermore, according to the resin container 10 according to the embodiment of the present invention, the edge portion 30E of the second panel 30 is provided with the first side portions 33C, 33C convex toward the side that is separated from each other. Also, a pair of opposing second side portions 33D, 33D along the circumferential direction of the container body 15 are provided with the convex side that is brought toward each other. As a result, the first side portions 33C, 33C act as ribs with respect to the arcuate surface 12A of the shoulder portion 12 and the arcuate surface 14A of the bottom portion 14, thereby ensuring strength as well.

[0050] Furthermore, according to the resin container 10 according to the embodiment of the present invention, among the eight panels consisting of the first panels 20, 21, the second panels 30, 31, and the third panels 40-43, the second panels 30 and 31 are provided with a concave design portion 34. Therefore, good gripping performance can be obtained regardless of the size of the user's hands and fingers, grip strength, or gripping position.

[0051] Furthermore, according to the resin container 10 of the embodiment of the present invention, the design portion 34 is made up of letters or pictures and has a depth dimension D1 of 0.5 mm or more. This allows the user's hand or fingers to grip it securely, resulting in good grip. In addition, the design portion 34 is recessed. Therefore, when the second label 52 is attached to the recess 33, the second label 52 can be attached neatly without protruding.

[0052] Next, in order to confirm the effect of the design portion 34, the inventors conducted a gripping test, described later, using a resin container 10 with the design portion 34 (product of the present invention) and a resin container without the design portion 34 (conventional product). The product of the present invention is identical to the container body 15 shown in Figures 1 to 15, and is provided with the design portion 34. The conventional product is almost identical to the product of the present invention, differing only in the presence or absence of the design portion 34. The test was conducted with the first label 51 and the second label 52 removed.

[0053] Next, we will explain the grip test. The subjects were eight men and women in their 20s and 30s with small hands (distance from wrist to middle fingertip less than 17 cm). The test method involved spreading jojoba oil on their dominant hand, holding the conventional product and the present invention product with that hand, and pouring the liquid into the caps. The subjects were then asked to rate the grip during pouring on an absolute scale using the following three-point scale. The average evaluation scores for the conventional product and the present invention were calculated, and the results are shown in Table 1.

[0054] (evaluation) 1: Slip off 2: You can hold it in place with some effort. 3: It can be easily held with light force.

[0055] [Table 1]

[0056] As is clear from Table 1, with the conventional product that lacked the design section 34, everyone's hands slipped off. In contrast, with the present invention, which is equipped with the design section 34, it was found that better gripping performance was obtained compared to the conventional product.

[0057] Furthermore, according to the resin container 10 according to the embodiment of the present invention, the edge portion 30E of the second panel 30 is provided with a convex shape on the side where the first edges 33C, 33C are separated from each other.
