Description

[Technical field]

[0001] The present invention relates to a multiple case for storing elongated objects, which can be separated at connecting portions. [Background technology]

[0002] Conventionally, as shown in Fig. 7(A), a multiple case 101 that can be separated at a connecting portion has been known as a case for storing long and thin tools such as drills, bits, and reamers (for example, Patent Document 1). This multiple case 101 is composed of a case body 110 in which a plurality of container members 111, 111, ... are connected in the width direction by container connecting members 112, and a cover body 120 in which the same number of lid bodies 121, 121, ... as the container members 111 of the case body 110 are connected in the width direction by lid body connecting members 122, and is configured so that the case can be separated at the positions of the connecting members 112, 122 to separate the case into individual containers and take out the stored items.

[0003] 7(B), the container connecting member 112 is a member for connecting and integrating the respective container members 111, and connects the respective container members 111, 111, ... at two longitudinal end portions. Similarly, the lid body connecting member 122 is a member for connecting and integrating the respective lid bodies 121, and connects the respective lid bodies 121, 121, ... at two longitudinal end portions. In addition, the container connecting member 112 is shaped to have a deep cut 112a on the lower surface side by connecting the upper portions of arc-shaped thin plates protruding from the side surfaces of the left and right container members, and the lid body connecting member 122 has a notch 122a formed on the upper surface side.

[0004] Patent Document 1 proposes a method of use in which an item can be removed by opening only one lid of a single container without dividing the container into individual containers, but also proposes irradiating a laser beam to separate the lid connecting member 122 or reducing the rigidity of the container connecting member 122 to make it easier to divide the container into individual containers.

[0005] [Patent Document 1] JP 2003-226386 (Fig. 3, Fig. 6) DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0006] Incidentally, such multiple case 101 is stored with case bodies 110 stacked one on top of the other, as shown in FIG. 7(C).

[0007] In this case, if an attempt is made to reduce the size of the package, as shown by the arrow, the container connecting member 112 of the upper case body may get caught in the opening of the lower case body, which may result in poor separability between the case bodies. On the other hand, if the case bodies are stacked without applying vertical force in order to increase the separability between the case bodies, the problem of the package size becoming larger arises.

[0008] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to reduce the size of a multiple case during storage without impairing the separability of stacked case bodies. [Means for solving the problem]

[0009] The multiple case of the present invention, which has been made to achieve the above-mentioned object, is composed of a case body formed by connecting a plurality of container members at equal intervals in the width direction, and a cover body formed by connecting the same number of lid members as the container members at equal intervals in the width direction, and is characterized in that the case body and the cover body are configured so that they have approximately the same overall width, and in that the length is configured so that one end of the cover body extends beyond the case body, and also has the following configuration. (1A) The case body is integrally molded by synthetic resin injection molding so that the multiple container members are connected in the width direction at predetermined longitudinal positions by container connecting members. (1B) Each of the plurality of container members has a housing portion that is elongated in the front-rear direction and has side surfaces inclined outward upward so that the bottom surface is narrower than the opening portion. (1C) The container connecting member is formed of a frustum-shaped plate member corresponding to the inclination of the side surfaces of adjacent container members, and an inverted V-shaped notch is formed from the lower surface of the central portion in the width direction thereof. At the lower end of the notch, it is connected to each side surface of the adjacent container member by a substantially horizontal flat surface.

[0010] According to the multi-connected case of the present invention, the case body can be stacked in multiple stages for packing, transportation, storage, etc. At this time, since the lower end of the container connecting member is connected to each side surface of the adjacent container member by a substantially horizontal flat surface, it is difficult for the lower end of the container connecting member to fit inside the container member of the lower case body. As a result, in the multi-connected case, it is possible to reduce the loading posture during storage etc. without reducing the separability of the stacked case bodies.

[0011] Here, the multi-connected case of the present invention can further be provided with the following configuration. (2) The flat surface is formed such that the relationship between the distance b2 between the outer ends of the flat surfaces connected to the left side wall and the right side wall of one container member and the inner dimensions b1 of the opening of the container member is [b1 < b2].

[0012] According to the multi-connected case having the configuration of (2), when stacking and storing the case body etc., it is possible to reliably prevent the container connecting member from fitting in.

[0013] The multi-connected case of the present invention can further be provided with the following configuration. (3A) The container connecting member has V-notches formed on the upper surface and the front and rear surfaces. (3B) The cover body is integrally formed by synthetic resin injection molding so that the plurality of lid bodies are connected in the width direction by a lid connecting member at a predetermined position in the longitudinal direction. (3C) The lid connecting member has V-notches formed on its top surface and its front and rear surfaces.

[0014] According to the multiple case having the configurations of (3A) to (3C), when the case body contains articles and the cover body is attached, the end storage container can be easily separated into individual storage containers by rotating the storage container toward the lid. In particular, by forming a V-notch on the top, bottom, and front and rear surfaces of the center of the container connecting member of the case body and forming a V-notch on the top, bottom, and front and rear surfaces of the center of the lid connecting member of the cover body, the connecting member does not stretch when separating into individual containers, which makes separation difficult. As a result, a soft synthetic resin can be used as the cover body. As a result, by slightly increasing the height of the rib, a cover body with high warping prevention effect can be constructed. It is preferable to set "(3D) the bottom surface of the lid connecting member is not provided with the V-notch" so that the individual lids are not torn off when handling the cover body alone. Furthermore, by setting "(3E) the container connecting member and the lid connecting member are formed so that they are vertically overlapped when the lid is closed", a force can be applied in a uniform direction when separating into individual storage containers.

[0015] The multiple case of the present invention may further include the following configuration. (4A) The front and rear walls of each of the plurality of container members are formed with engaging recesses for engaging with the claw members of the lid body when the lid is closed. (4B) The multiple lid bodies are made of strip-shaped band members that are long and narrow in the front-to-rear direction, and on the container member side when the lid is closed, the claw members include a first claw member that engages with the engagement recess on the side of the cover body that protrudes from the case body, and a second claw member that does not protrude and engages with the engagement recess on the opposite side to the protruding side, as well as a first backing member that clamps the container member together with the first claw member, a second backing member that clamps the container member together with the second claw member, and left and right ribs that fit into the inner surface of the opening of the container member when the lid is closed. (4C) The first backing member is divided at its center in correspondence with the width of the first claw member.

[0016] The multiple case of the present invention may further include the following configuration. (5) An opening penetrating the band plate member is formed between the second backing member and the second claw member, and a thin-walled portion having the same thickness as both side portions of the band plate member is formed on the opposite side of the opening of the second backing member.

[0017] According to a multiple case having the configurations of (4A) to (4C), a slide die can be used to form the first claw member. As a result, it is not necessary to penetrate the strip-shaped member with an opening for forming the second claw member, and the problem of the part pinched by the fingers breaking when opening the lid and making it difficult to open does not occur. Furthermore, if it is further specified that "(4D) a flat convex portion is formed over a predetermined range from the first claw member at the divided portion of the first backing member," this is effective in smoothly executing the retraction operation of the slide die.

[0018] In contrast, according to the multiple case having the configuration of (5), there is no need to form a divided portion in the second backing member, and as a result, even if a thin-walled portion is formed, the strength of the lid body is not significantly reduced. On the contrary, by providing a thin-walled portion, the belt-shaped member is easily bent in the vicinity of the second backing member. As a result, it becomes easy to release the clamping by the first claw member and the first backing member while the container member is still clamped by the second claw member and the second backing member, and the stored article can be removed without dropping it. In addition, since the thin-walled portion does not penetrate the width direction of the belt plate member, oil applied to the stored article does not leak. Effect of the Invention

[0019] According to the present invention, in a multiple case, the packaging size during storage or the like can be made compact without impairing the separability of stacked case bodies. [Brief description of the drawings]

[Figure 7] FIG. 1 is an explanatory diagram of a conventional technique. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] The multiple case of this embodiment will be described below based on examples. EXAMPLES

[0022] As shown in Fig. 1(A), the multiple case 1 of this embodiment is composed of a case body 10 in which a plurality of container members (10 in this embodiment) are connected at equal intervals in the width direction, and a cover body 20 in which the same number of lid members as the container members are connected at equal intervals in the width direction. The case body 10 and the cover body 20 are configured to have approximately the same overall width, and as for the length, one end of the cover body 20 is configured to protrude beyond the case body 10, as shown in Fig. 1(B).

[0023] As shown in Figures 1(C) and 2, the case body 10 is integrally molded by synthetic resin injection molding so that multiple container members 11, 11, ... are connected in the width direction by container connecting members 12, 12, ... at two points near the longitudinal ends.

[0024] As shown in Figures 2(A) to 2(C), each container member 11 is elongated in the front-rear direction and has a storage section with its sides inclined upward and outwardly open so that the bottom surface is narrower than the opening. As shown in Figures 2(A) and 2(D), engagement recesses 14 are formed on the front and rear walls of each container member 11 for engaging with the claw members of the lid body 21 when closing the lid. Also, as shown in Figure 2(B), four partition plates 15, 15, ... are integrally formed at the bottom of each container member 11 at approximately equal intervals. As shown in Figure 5(D), the partition plate 15 is formed in a plate shape having an arc-shaped receiving portion, and is intended to store a round bar-shaped article W in a state of being supported from below so as to embrace it, as shown in Figure 5(E).

[0025] 1(C) and 3, the cover body 20 is integrally molded by synthetic resin injection molding so that a plurality of lid bodies 21, 21, ... are connected in the width direction by lid body connecting members 22, 22, ... at two points near the longitudinal ends. In this embodiment, the container connecting members 12, 12, ... of the case body 10 and the lid body connecting members 22, 22, ... of the cover body 20 are formed in positions that overlap vertically when the lid is closed.

[0026] 3(B) and (C), each lid body 21 is formed of a strip-like member 31 that is elongated in the front-rear direction and whose portion protruding from the container member 11 narrows toward its tip. On the bottom side of the strip member 31 (the container member side when the lid is closed), as shown in FIG. 3(C), a rib 32, a finger hook member 33, a first claw member 34a, a first backing member 35a, a second claw member 34b, and a second backing member 35b are formed.

[0027] Two ribs 32 are formed at intervals in the width direction so as to fit into the inner surface of the opening of the container member 11 when the lid is closed. The finger hook member 33 is for hooking fingers when opening the lid body 21, and is provided on a portion protruding from the container member. The first and second claw members 34a, 34b and the first and second backing members 35a, 35b engage with the engagement recesses 14, 14 formed on the upper part of the front and rear walls of each container member 11, and hold the front and rear walls together to maintain the lid closed state.

[0028] Here, the first backing member 35a formed on the protruding side is divided at the center corresponding to the width of the first claw member 34a also formed on the protruding side. This divided part is formed slightly wider than the width of the first claw member 34a, and is for allowing the sliding parts of the die for forming the first claw member 34a to pass through the space between them, and a rectangular flat convex part 37 is formed over a predetermined range from the first claw member 34a to facilitate sliding during this process.

[0029] The second backing member 35b on the opposite side to the protruding portion does not have a divided portion, but instead has an opening 36 for allowing a die portion for forming the second claw member 34b to penetrate through the band plate member 31. Also, on the opposite side to the opening 36 of the second backing member 35b, as shown in Figures 3(C) and 4(G) and (D), thin-walled portions 38 are formed that have the same thickness as both side portions of the band plate member 31.

[0030] As shown in Figs. 1(C), (D) and Figs. 4(A) to (C), the container connecting member 12 is integrally formed between the side surfaces of adjacent container members. The container connecting member 12 is composed of a fan-shaped plate member corresponding to the inclination of the side surfaces of adjacent container members, and V-notches 12a, 12c, 12d are formed on the upper surface and the front and rear surfaces. Further, an inverted V-shaped notch (V-notch) 12b is provided at the lower end portions of the V-notches 12c, 12d on the front and rear surfaces. As a result, the container connecting member 21 has V-notches 12a to 12d on the upper and lower surfaces and the front and rear surfaces at the central portion in the width direction thereof. Further, substantially horizontal flat surfaces 13a, 13b are formed at the lower end of the container connecting member 12. As shown in Fig. 5(B), the flat surfaces 13a, 13b are formed such that the distance b2 between the outer ends of the flat surface 13a on the left side and the flat surface 13b on the right side of one container member satisfies the relationship b1 < b2 with respect to the inner dimension b1 of the opening of the container member.

[0031] As shown in Figs. 4(D) to (F), the lid connecting member 22 is integrally formed between the side surfaces of adjacent lids. V-notches 22a, 22c, 22d are formed on the upper surface and the front and rear surfaces of the lid connecting member 22, excluding the lower surface.

[0032] Next, the operation and effects of the multi-connected case 1 of the present embodiment will be described. Since the case body 10 of the multi-connected case 1 connects a plurality of (ten in this embodiment) container members at equal intervals in the width direction, as shown in Fig. 5(A), it can be packed, transported, stored, etc. in a stacked state. At this time, as described above, since the distance b2 between the outer ends of the flat surface 13a on the left side and the flat surface 13b on the right side of one container member satisfies the relationship b1 < b2 with respect to the inner dimension b1 of the opening of the container member, as shown in Fig. 5(B), when the case bodies are stacked, the container connecting members 12 can be prevented from fitting into the inside of the openings of the respective container members of the lower case body, and they can be stacked. Further, at this time, when the height of the container member is h1 and the height from the bottom surface of the container member to the flat surfaces 13a, 13b is h2, the overall height H in the state where n case bodies are stacked is [H = n * h1 - (n - 1) * h2], and the loading posture can be reduced by [(n - 1) * h2].

[0033] On the other hand, since the stacked case bodies are not fitted together, for example, when an automatic machine removes the case bodies, two or more will not be fed onto the assembly line overlapping each other. In the case body 10 thus fed onto the assembly line, an article W can be stored and a cover body 20 can be attached, as shown in Figures 5(C) to (E), so that multiple articles can be stored individually.

[0034] When the multiple case 1 assembled in this manner is rotated upward (in the X direction) as shown in Fig. 6(A), the end case can be easily separated as shown in Fig. 6(B) by the action of V-notches 12a-12d of case body 10 and V-notches 22a, 22c, 22d of cover body 20. In particular, by forming container connecting member 12 and lid connecting member 22 so that they overlap vertically when the lid is closed, force can be applied in a uniform direction when separating the individual storage containers.

[0035] When removing an article from each case thus divided, as shown in FIG. 6(C), the lid can be opened by hooking the finger on the finger hook member 33 of the lid body 20 and lifting it upward (Y direction in the figure) as shown in FIG. 6(D). In this embodiment, the first backing member 35a, which clamps the front wall of the container member 10 together with the first claw member 34a of the protruding portion, is formed in a centrally divided shape, so that there is no need to provide a through hole for forming the first claw member 34a, and therefore the protruding portion of the lid body 20 will not break even if force is applied to open the lid. On the other hand, the thin-walled portion 38 is formed near the second backing member 35b on the opposite side of the protruding portion, so that the thin-walled portion 38 is easily bent. As a result, it is easy to open the lid to the state shown in FIG. 6(D), and the stored article can be removed without dropping it.

[0036] As shown in Fig. 4(H), the thin portion 38 does not penetrate the width direction of the band plate member 31. Therefore, oil or the like applied to the stored items does not leak out.

[0037] Furthermore, in the multiple case 1 of this embodiment, V-notches 12a-12d are formed on the top, bottom, front and rear surfaces at the center of the container connecting member 12 of the case body 10, and V-notches 22a, 22c, 22d are formed on the top, bottom and front and rear surfaces at the center of the lid connecting member 22 of the cover body 20, so that the connecting members do not stretch when the case 1 is divided into individual containers, which makes it difficult to divide the case. As a result, a soft synthetic resin can be used for the cover body 20. As a result, by slightly increasing the height of the rib 22, a cover body with high warping prevention effect can be constructed.

[0038] Although the embodiment and examples of the present invention have been described above, the present invention is not limited to these and can be embodied in various ways without departing from the spirit and scope of the present invention. [Industrial Applicability]

[0039] It can be used as a storage container. [Explanation of symbols]
