Description

  The present invention relates to a lead-acid battery outer box for packing a lead-acid battery.

  Lead-acid batteries used as automobile cell starters are formed by folding cardboard or the like to display information such as battery rank and size while preventing damage during transportation when distributed for repair at home centers and the like. It is stored in the outer box.

  A conventional exterior box is a substantially rectangular parallelepiped along the shape of the lead storage battery to be packed, for example, as shown in the developed view of FIG. On the four side surfaces 1, a flap 2 or 3 constituting the upper surface and a flap 4 or 5 constituting the lower surface are continuously formed. First, the joining piece 1a provided on the side surface 1 at one end is joined to the joined portion 1b on the side surface 1 at the other end to form a cylindrical body. Next, the flaps 4 are folded at a right angle with respect to the side surface 1 so as to face each other, and the flaps 5 are folded at a right angle with respect to the side surface 1 so as to face each other, and the flaps 4 and 5 are joined with an adhesive or the like. This constitutes the lower surface. In this state (the state where only the upper surface is not configured), the lead-acid battery is inserted, the flaps 2 with the slits 2a cut out are bent at right angles to the side surface 1 and faced, and the flaps 3 are placed on the side surface 1 The lead-acid battery is constructed by forming a top surface that can be opened and closed by bending the plug 3 at a right angle with respect to each other, and finally inserting an insertion portion 3a provided at the tip of the flap 3 into a pair of opposed slits 2a. The enclosed outer box is completed. Here, in order to facilitate the transportation of the outer box, especially in a large lead-acid battery (alphabet D or E is used in JISD5301), a hand hole 1c for inserting a hand is formed in a pair of side surfaces 1 facing each other. It is common to do. In the case of the exterior box having the developed view shown in FIG. 2, the lower surface can be configured by fitting by joining the complicated shapes of the tips of the flaps 4 and 5 without joining with an adhesive or the like.

  The outer box in which the hand holes 1c are randomly provided cannot withstand the weight of the lead-acid battery during transportation and may be damaged from the periphery of the hand holes 1c. Therefore, as in Patent Document 1, a cut is made in a part of the side surface 1 so that the hand hole 1c is formed, and the lead storage battery is surrounded by a protective frame, and when the hand hole 1c is formed, the inside of the outer box is formed. The structure which improves the mechanical strength in the periphery of the hand hole 1c is proposed by hitting a part of the side surface 1 bent to the protective frame (or the boundary between the lid of the lead storage battery and the battery case housed in the protective frame). Yes.

JP 2004-146087 A

  In recent years, in home centers and the like, efforts to make effective use of the limited sales floor space are expanding. For example, in the configuration of Patent Document 1, a space for inserting a protective frame and a space for folding a part of the side surface 1 into the exterior box when a part of the side surface 1 forms the hand hole 1c are required. It becomes difficult to make effective use of the area. In order to prevent damage to the exterior box centering around the periphery of the hand hole 1c in a state where the characteristic configuration of Patent Document 1 is omitted, it is considered that the user should carefully insert the hand into the hand hole 1c and carry it.

  However, at home centers, as a part of the above efforts, the lead-acid batteries for repair packed in the outer box have been displayed on a shelf with a height that does not allow room to move up and down. In this aspect, when a customer or employee of the home center inserts or removes the lead-acid battery, an operation of placing the hand in the hand hole 1c provided on the side surface 1 of the outer box and drawing it horizontally is required. In such an embodiment, it has been clarified that the periphery of the hand hole 1c is more likely to be damaged as compared with the case where it is moved up and down no matter how carefully it is pulled. This problem did not occur in exterior boxes that had a lead-acid battery with a belt-like handle, and that was designed to bring the handle out of the box for the convenience of customers and employees. There wasn't.

  The present invention is for solving such problems, and in a lead-acid battery outer box that is not shaped to take out the handle out of the box, even in a packing form or display form with improved volume efficiency, The purpose is to prevent breakage around the periphery of the hand hole.

  In order to solve the above-described problem, the invention according to claim 1 of the present invention is characterized in that a pair of slits formed by facing a pair of flaps each having a notched slit provided with a hand hole in a pair of opposing side surfaces. A substantially rectangular parallelepiped lead-acid battery outer box having an upper surface that can be opened and closed by inserting an insertion portion provided at the tip of a pair of flaps, the width of the slit at the tip of the flap being the slit at the deepest portion of the flap It is characterized by being larger than the width of.

  The invention according to claim 2 of the present invention is characterized in that, in claim 1, a parallel portion having substantially the same width of the slit is provided in the vicinity of the deepest portion of the flap.

  The invention according to claim 3 of the present invention is characterized in that, in claim 1, the upper end of the hand hole is set at a position of 19 to 71% in the height direction of the side surface.

  As a result of intensive studies, the inventors applied stress to the periphery of the hand hole 1c by the hand pulling on the hand hole 1c provided on the side surface 1 of the exterior box and pulling it horizontally. It has been found that it is much larger than the stress caused by the conventional movement. The mechanism of this new problem and the effect of the present invention is shown in FIG. In FIG. 3, the insertion portion 3a inserted into the slit 2a is omitted for convenience of explanation.

  When a customer or employee such as a home center draws the outer box packed with lead-acid batteries horizontally from a state where it is displayed on a shelf that is not high enough to move up and down, it is drawn into the hand hole 1c provided on the side surface 1 It will be pulled and pulled in the direction of arrow α. At this time, stress is applied to the portion of the side surface 1 above the hand hole 1c in the direction of the arrow β. This stress easily breaks the periphery of the hand hole 1c, but if the flap 2 can be drawn from a dotted line to a solid line (inward along the arrow γ), the arrow β The corresponding stress can be relieved and the damage can be avoided.

  The present inventors make use of this knowledge to make the slit 2a provided in the flap 2 consistently in the substantially parallel (parallel) shape as in the prior art, and the width at the tip of the flap 2 at the deepest portion. By enlarging the width, the deformation along the arrow γ is promoted, and even if the hand hole 1c is put in a hand and pulled in the direction of the arrow α, the periphery of the hand hole 1c is not damaged by the stress corresponding to the arrow β. I made it.

  According to the present invention, since the strength around the hand hole when moving the lead-acid battery outer box in the horizontal direction can be improved, the hand hole provided on the side surface of the outer box in the packaging form with improved volumetric efficiency. Even if the hand is pulled and pulled, damage around the periphery of the hand hole is less likely to occur.

The figure which shows the suitable position of the hand hole in the exterior box for lead acid batteries of this invention The figure which shows the various aspects of the hand hole in the exterior box for lead acid batteries of this invention

  The form for implementing the exterior box for lead acid batteries of this invention is demonstrated using figures.

(First embodiment of the present invention)
FIG. 4 is a view showing an example of a main part of the lead-acid battery outer box of the present invention. Specifically, only the flap 2 provided with the slit 2a is extracted. In addition, in the 1st Embodiment of this invention, the other site | part of an exterior box is the same as FIGS.

  First, a pair of flaps 2 in which slits 2a are cut out are faced to each other, and an insertion portion 3a provided at the tip of another pair of flaps 3 is inserted into the pair of slits 2a. The upper surface which can be opened and closed is comprised by the exterior box. The first embodiment of the present invention is characterized in that the width A of the slit 2a at the tip of the flap 2 is larger than the width B of the slit 2a at the deepest portion.

  With this configuration, a hand is placed on the hand hole 1c provided on the side surface 1 and pulled in the direction of arrow α in FIG. 3, and stress in the direction of arrow β is applied to the side surface 1 above the hand hole 1c. However, since the slit 2a (width A) at the tip of the flap 2 can be deformed along the arrow γ until the slit 2a is substantially the same as the width B, the periphery of the hand hole 1c is not damaged.

(Second embodiment of the present invention)
FIG. 5 is a view showing another example of the main part of the lead-acid battery outer box of the present invention. Specifically, only the flap 2 provided with the slits 2a is extracted. In addition, in the 2nd Embodiment of this invention, the other site | part of an exterior box is the same as FIGS. Hereinafter, the difference from FIG. 4 will be mainly described.

  In the first embodiment of the present invention, the width of the slit 2a gradually decreases from the tip (width A) of the flap 2 to the deepest portion (width B) (so-called “V-shape”). However, in the second embodiment of the present invention, a parallel portion 2b having substantially the same width of the slit 2a is provided in the vicinity of the deepest portion of the flap 2 (so-called “Y-shape”).

  By adopting such a form, the fixing property when the insertion portion 3a provided at the tip of the flap 3 is inserted into the facing slit 2a is improved without impairing the effect of the first embodiment of the present invention. To do. That is, when the insertion portion 3a is inserted and held firmly by the parallel portion 2b, the front end of the flap 2 when the hand hole 1c provided in the side surface 1 is placed and pulled in the direction of the arrow α in FIG. Can be deformed until the slit 2a (width A) is substantially the same as the width B (the periphery of the hand hole 1c is not damaged).

(Third embodiment of the present invention)
FIG. 6 is a view showing a suitable position of the hand hole 1c in the lead-acid battery outer box of the present invention, and specifically, it is extracted centering on the side surface 1 provided with the hand hole 1c. In addition, in the 3rd Embodiment of this invention, the other site | part of an exterior box is the same as FIGS.

  In the present invention, when the hand hole 1c is excessively upward in the vertical direction, the stress (arrow β) when pulled in the direction of the arrow α in FIG. 3 is sufficiently relaxed in the direction of the arrow γ (of the flap 2). Since the slit 2a (width A) at the tip cannot be sufficiently narrowed), the periphery of the hand hole 1c may be damaged within a range that does not hinder transportation.

  On the contrary, in the present invention, when the hand hole 1c is excessively below in the vertical direction, for example, a customer or employee who wants to pull out the lead storage battery (exterior box) displayed at the bottom of the multi-stage rack is as shown in FIG. In this case, the palm must be pulled in the direction of the arrow α in FIG. 3 with the palm facing down (by hooking the lower side of the hand hole 1c). It is extremely difficult to switch from this state to the operation of placing the hand in the hand hole 1c (with the palm up) and lifting the lead storage battery (exterior box).

  Therefore, by setting the upper end of the hand hole 1c at a position of 19 to 71% in the height direction of the side surface 1, the effect by the configuration of the slit 2a shown in the first and second embodiments of the present invention is remarkably exhibited and high. Workability can be secured.

  As shown in FIG. 6, the position of the upper end of the hand hole 1c in the height direction of the side surface 1 is the distance d from the upper end of the side surface 1 (the side joined to the flap 2) to the upper end of the hand hole 1c. It can be obtained by dividing by the height H of the side surface (d / H × 100 when expressed as a percentage).

  In addition to the standard shape shown in FIG. 6, the shape of the hand hole 1 c is elliptical (a) as shown in FIG. 7, and the upper half is folded inward from a crease (broken line / the same applies hereinafter) (b). Examples include a case where the upper and lower halves are folded inward from the crease (c), and a case in which a hole is first formed by folding inward from the crease (d). In any of the cases shown in FIG. 7, the height at which the palm is applied (corresponding to the fold in (b) to (d)) corresponds to the “upper end of the hand hole 1c” in the present invention.

Various cardboards having a basis weight of 125 to 300 g / m ² can be used for the outer box. In addition, as the lead acid battery, an open type lead acid battery having a liquid stopper and requiring replenishment maintenance may be selected, or a control valve type lead acid battery having a control valve and not requiring replenishment maintenance may be selected. .

  In addition, in the case of an exterior box with a belt-like handle attached to the lead-acid battery and taking this handle out of the box for the convenience of customers and employees, a gap corresponding to the width of the handle is flapped in addition to the slit 2a. 2 will be provided. Since this gap expresses the same effect as the slit 2a of the present invention (by moderately deforming, the stress indicated by the arrow β in FIG. 2 is relieved), the problem that led to devising the present invention did not occur. Inferred.

  Next, the results of various studies on the configuration of the outer box will be shown.

  A lead-acid battery represented by 95D31 in JIS D5301 (lead-acid battery for starting) is a conventional exterior box shown in FIG. 1 (A-1 to 4, slit 2a is only a parallel part having a width of 6 mm), and the present invention shown in FIG. The outer box (B-1 to 4, the slit 2a gradually decreases in a V shape from A = 14 mm to B = 6 mm, the lower surface is the same as in FIG. 1) and the outer box of the present invention shown in FIG. -4, the slit 2a gradually decreases in a V shape from A = 14mm to B = 6mm and then reaches the deepest part with a length of 15mm and a parallel part with a width of 6mm / generally Y-shaped, the bottom is the same as FIG. And the flaps 2 and 3 were joined together and packed. Here, the lead storage battery was not covered with a cushioning material such as a protective frame, and the inner dimension of the outer box was assumed to have a margin of 2 mm from the outer dimension of the lead storage battery. In addition, A-1 to 4, B-1 to 4 and C-1 to 4 are configured by changing the position of the hand hole 1c (ellipse shape having a height of 25 mm and a width of 80 mm), and “d / H (%) "

  A jig was hooked into the hand hole 1c of these objects, and a standard adult male performed an action of pulling horizontally at a speed of 100 cm / second, and the degree of damage around the hand hole 1c was compared.

  “○” indicates that there is no appearance damage around the hand hole 1c, “△” indicates that the periphery of the hand hole 1c is damaged to the extent that it does not hinder transportation, and hinders transportation around the hand hole 1c. Table 1 shows the case where a certain breakage occurred as “x”.

  As is clear from the results of (Table 1), when the exterior boxes A-1 to A-4 having the conventional slit 2a are hooked on the hand hole 1c and pulled horizontally regardless of the position of the hand hole 1c. In the vicinity of the hand hole 1c, damage occurred that hinders transportation.

  Compared to this, the exterior boxes B-1 to C4 and C-1 to C-4 having the slits 2a of the present invention have a hindrance to transportation around the hand hole 1c even if the hand hole 1c is hooked and pulled horizontally. Some damage did not occur. This effect is considered to be based on the mechanism shown in FIG.

  The effect of the present invention is most conspicuous when the upper end of the hand hole 1c is 19% in the height direction of the side surface 1 and is positioned below it (B-2 to 4 and C-2 to 4). Met. In this example, since it was obvious that there was difficulty in handling if the upper end of the hand hole 1c was positioned below 71% in the height direction of the side surface 1, evaluation on breakage was not performed.

  According to the configuration of the present invention, it is possible to provide an exterior box for a lead storage battery in which a hand hole is not easily damaged when moving in the horizontal direction without increasing the number of parts such as a protective frame. Suitable for lead-acid storage batteries for automobile repair. Therefore, the industrial value of the present invention is extremely high.
