This application claims priority to Korean Patent Application No. 10-2012-0100275 (filed on Sep. 11, 2012) and Korean Patent Application No. 10-2013-0098267 (filed on Aug. 20, 2013), the entire subject matters of which are incorporated herein by reference.
The present invention relates to a wiper blade package for receiving a wiper blade therein.
A wiper blade for use in wiping a windshield of a motor vehicle has a wiper strip. The wiper strip is worn due to contact with the surface of a windshield. When the service life of a wiper strip comes to an end, the wiper blade is replaced with a new one. New wiper blades may be purchased at car accessory shops. Typically, wiper blades are displayed in the car accessory shops as contained in packages.
The package for receiving a wiper blade must be designed so as to appropriately receive a long wiper blade. Further, the package must be designed such that the wiper strip of a wiper blade and parts for securing the wiper strip is protected during handling or transportation. International Patent Application Publication No. WO 2008/036964 discloses a package for receiving a flat wiper blade.
When a consumer purchases a wiper blade, the consumer takes a wiper blade out of the package and then inspects the wiper blade and its wiper strip. Then, after inspection, the consumer puts the wiper blade into the package again. If the mouth portion of the package cannot be easily opened or closed, it could be troublesome or inconvenient for the consumer when the wiper blade is taken out and put back into the package. Further, the package must be structurally rigid in order to protect the wiper blade received therein and the parts of the wiper blade. When the package falls to the ground, the wiper blade received therein can come out of the package, and when many packages are piled together within a box, the package can become compressed. This may cause damage of the wiper blade received in the package.
However, conventional wiper blade packages have limits regarding easy opening of the mouth portion of the package through simple manipulation. Further, conventional wiper blade packages are unsatisfactory in terms of structural rigidity.
The present invention is directed to solving the aforementioned problems. The present invention provides a wiper blade package wherein a mouth portion can be opened with simple manipulation. Further, the present invention provides a wiper blade package wherein a mouth portion and a bottom portion are constructed with a strong structure. Further, the present invention provides a wiper blade package that can be closely piled within a box.
According to various aspects, there are provided numerous embodiments of a wiper blade package wherein a mouth portion is openable by being pressed in a lateral direction.
In one exemplary embodiment, a wiper blade package includes a receiving portion having a receiving cavity that is surrounded by a first panel, a second panel, a first side panel and a second side panel. The first panel is bendable around a first bend line that extends in a longitudinal direction between both lateral edges. The first panel has a lid flap at a longitudinal end. The lid flap is foldable around the first bend line and is pivotable around a first hinge line which intersects the first bend line at an acute angle in an inward direction. The second panel is opposed to the first panel and has a first engagement flap folded toward the first panel at a longitudinal end. The first side panel extends along opposing edges of the first panel and the second panel. The second side panel extends along edges opposed to the opposing edges of the first panel and the second panel. The lid flap engages a free end of the first engagement flap at its free end and thereby closes the receiving portion. Further, by pressing the first and second side panels toward the receiving portion, the lid flap is pivoted from the first engagement flap and thereby opens the receiving portion.
In an embodiment of the present invention, the lid flap has, at its free end, at least one engagement tab which engages the free end of the first engagement flap. In a closed position where the lid flap closes the receiving portion, the engagement tab intervenes between the first engagement flap and the second panel. In such an embodiment, the first engagement flap may have an engagement notch, to which a fixed end of the engagement tab is fitted, at its free end. Further, the free end of the lid flap may be situated more outwardly than the free end of the first engagement flap in the closed position where the lid flap closes the receiving portion. Further, the lid flap has a pair of halves divided by the first bend line. The pair of the halves are folded around the first bend line in the closed position where the lid flap closes the receiving portion.
In an embodiment of the present invention, the first panel has a bottom flap at a longitudinally opposite end. The bottom flap is foldable around the first bend line and is pivotable around a second hinge line intersecting the first bend line at an acute angle in an inward direction. The second panel has a second engagement flap folded toward the first panel at a longitudinally opposite end. The bottom flap has at least one engagement tab, which is inserted in between the second engagement flap and the second panel, at a free end thereof. In such an embodiment, the second engagement flap may have an engagement notch, to which a fixed end of the engagement tab of the bottom flap is fitted, at the free end thereof. Further, when the bottom flap is in engagement with the second engagement flap, the free end of the bottom flap may be situated more outwardly than the free end of the second engagement flap. Further, the bottom flap has a pair of halves divided by the first bend line. When the bottom flap is in engagement with the second engagement flap, the pair of the halves of the bottom flap are folded around the first bend line.
In an embodiment of the present invention, the second panel is bendable around a second bend line extending in a longitudinal direction between both lateral edges.
In an embodiment of the present invention, the lid flap has a shape of a pentagon or hexagon.
In an embodiment of the present invention, the wiper blade package further includes hanging holes perforated through the second panel and the first engagement flap.
Arrangements and embodiments may be described in detail with reference to the following drawings in which like reference numerals refer to like elements or components, wherein:
Detailed descriptions will be made as to embodiments of a wiper blade package with reference to the accompanying drawings.
The directional term “upper,” “upward” or the like as used herein is based on a direction in which a lid flap is located relative to a second panel in a wiper blade package shown in the accompanying drawings, while the directional term “lower,” “downward” or the like refers to a direction opposite to the upper or upward direction. Further, as used herein, the directional term “front,” “frontward” or the like is based on a direction in which a hanging hole is located relative to a bottom flap in the wiper blade package shown in the accompanying drawings, while the directional term “rear,” “rearward” or the like refers to a direction opposite to the front or frontward direction. The wiper blade package shown in the accompanying drawings may be otherwise oriented and the aforementioned directional terms may be interpreted accordingly. Further, as used herein, the directional term “inward”, “inner” or the like means a direction directed toward a center of the wiper blade package, while the directional term “outward,” “outer” or the like means a direction opposite to the inward or inner direction.
The term “fold line” as used herein means a line that is located between two parts adjacent to one another via such a line when one part of said two parts is foldable toward the other part or said two parts are foldable toward each other. Further, as used herein, the term “hinge line” means a line that is located between two parts adjacent to one another via such a line when one part of said two parts is pivotable relative to the other part of said two parts. Further, as used herein, the term “bent,” “bending” or the like means that two sections divided by a line in a panel or flap of the wiper blade package are elastically movable toward or away from each other and the line located between said two sections are referred to as “a bend line.” Further, said fold line may be understood as including said hinge line and said bend line.
The wiper blade package (hereinafter, simply referred to as “package”) according to embodiments is configured to receive a wiper blade therein. Exemplary articles to be received by the package are not limited to a wiper blade and may include other elongated articles.
The package according to embodiments has a receiving portion that extends in a longitudinal direction of the package and receives the wiper blade. The receiving portion has a receiving cavity which is surrounded by a plurality of panels forming a body of the package. In the plurality of panels, two adjacent panels may be moved toward or away from each other around their common edge. In one embodiment, said plurality of panels comprise: a first panel located upwardly in the package; a second panel located downwardly in the package opposite the first panel; and two side panels extending along opposing lateral edges of the first and second panels, respectively. The first and second panels have a bend line that extends in a longitudinal direction between the lateral edges. In this embodiment, the cross-sectional shape of the receiving portion becomes a hexagon. In another embodiment, the second panel consists of a unitary panel without the bend line. In this embodiment, the cross-sectional shape of the receiving portion becomes a pentagon.
In the package according to embodiments, a pentagonal or hexagonal lid flap, which is pivotable to open or close the receiving portion, is disposed at a mouth portion of the receiving portion. In one embodiment, the lid flap comprises two halves that are foldable around the bend line. The lid flap is integrally formed to a longitudinal end of the first panel via a hinge line. The lid flap is pivotable between a closed position where the receiving portion is closed and an open position where the receiving portion is opened.
In the package according to embodiments, the hinge line of the lid flap intersects the bend line at an acute angle in an inward direction. If a force or pressure is applied to the first panel in a lateral direction, then the lid flap is pivoted toward the inside of the receiving portion due to the angle of the hinge line relative to the bend line. Further, since the lid flap is foldable around the bend line of the first panel, the lid flap is pivoted toward the inside of the receiving portion while the two halves divided by the bend line are folded convexly toward the inside of the receiving portion. Through the aforementioned folding action and pivoting action, the lid flap opens the receiving portion. If the force or pressure is removed, the lid flap reverts to the closed position due to the restoration force of the first panel.
The package according to embodiments has a first engagement flap for maintaining the lid flap in the closed position. In one embodiment, the first engagement flap is integrally formed to a longitudinal end of the second panel and is folded toward the first panel, i.e., toward the inside of the receiving portion. Further, the lid flap is maintained in the closed position as engaged with a free end of the first engagement flap at its free end. In one embodiment, the lid flap has, at its free end, an engagement tab intervening between the second panel and the first engagement flap in the closed position. Further, to ensure the fixation of the lid flap in the closed position, an engagement notch is provided at the free end of the first engagement flap and a fixed end of the engagement tab of the lid flap is fitted to the engagement notch in the closed position. Further, in the closed position, the free end of the first engagement flap is more inward than the free end of the lid flap. Thus, although a force pushing or pivoting the lid flap out of the closed position is applied to the lid flap, a portion of the first engagement flap, which is more inward than the free end of the lid flap, allows the lid flap to be maintained in the closed position.
In the package according to embodiments, the bottom portion of the receiving portion is constructed using the aforementioned engagement configuration between the lid flap and the first engagement flap. In one embodiment, the first panel has a bottom flap at its longitudinally opposite end and the second panel has a second engagement flap at its longitudinally opposite end. The bottom flap has the same configuration as the lid flap and the second engagement flap has the same configuration as the first engagement flap. The bottom flap engages a free end of the section engagement flap at its free end, thereby forming the bottom portion. The bottom flap is pivotable between an open position where the bottom portion is opened and a closed position where the bottom portion is closed. The free end of the second engagement flap is more inward than the free end of the bottom flap. Thus, although a force perpendicular to the bottom flap is applied to the bottom flap engaged with the section engagement flap, the bottom flap cannot be pivoted outward due to the engagement with the second engagement flap.
The package according to embodiments is capable of resisting a perpendicular load at the mouth portion and the bottom portion of the receiving portion. In the lid flap situated in the closed position and the bottom flap forming the bottom portion, the two halves divided by the bend line of the first panel are folded around the bend line and the bend line between the two halves are situated perpendicularly to the first panel or the second panel. Accordingly, the bend line and the two folded halves in the lid flap or the bottom flap can resist the perpendicular load.
Said wiper blade to be received in the package 100 may include a yoke type wiper blade 10 shown by dashed lines in
The yoke type wiper blade 10 includes an elongated wiper strip 11 made of a rubber or elastomer material and a frame assembly 12 supporting and holding the wiper strip 11. The frame assembly 12 comprises one main yoke 12a and a plurality of sub yokes joined to the main yoke 12a in a bifurcated shape. Clamps 12c provided at distal ends of the sub yokes 12b secure the wiper strip 11.
The flat wiper blade 20 includes an elongated wiper strip 21 made of a rubber or elastomer material and one elongated flat bar 22 supporting and holding the wiper strip 11. The flat bar 22 is curved with a certain curvature. The wiper strip 21 is secured to the flat bar 22 as fitted to a longitudinal slot formed in the flat bar 22.
Referring to
The first panel 120 has a first bend line 121 that extends in a longitudinal direction between both edges 114, 115 located in a lateral direction. The first panel 120 is divided into two sections 120a, 120b relative to the first bend line 121. The first panel 120 may bend around the first bend line 121 due to a force acting in the lateral direction. That is, the two sections 120a, 120b of the first panel 120 may be elastically moved toward or away from each other with respect to the first bend line 121. The second panel 130 has a second bend line 131 that extends in a longitudinal direction between both edges 116, 117 located in a lateral direction. The second panel 130 is divided into two sections 130a, 130b relative to the second bend line 131. The second panel 130 may bend around the second bend line 131 due to a force acting in the lateral direction. That is, the two sections 130a, 130b of the second panel 130 may be elastically moved toward or away from each other with respect to the second bend line 131.
The first side panel 140a is located between the first panel 120 and the second panel 130. Thus, the first side panel 140a extends along the opposing edges 115, 117 of the first panel 120 and the second panel 130. As shown in
The first side panel 140a and the second side panel 140b have an extension flap 142 at either longitudinal end. The extension flap 142 is integrally formed to the first side panel 140a or the second side panel 140b via a fold line 147 and may be folded toward the inside of the receiving portion 110. In the assembled package 100, the extension flap 142 is situated more inward than a lid flap and a bottom flap, which are described below.
When assembling the package sheet 100′ into the package 100, the first panel 120 is folded such that the first bend line 121 protrudes upward, while the second panel 130 is folded such that the second bend line 131 protrudes downward. As shown in
The package 100 includes a lid flap 150 that is disposed at the mouth portion 112 of the receiving portion 110 and forms the mouth portion 112. In this embodiment, the hexagonal lid flap 150 is integrally formed to the longitudinal end or front end of the first panel 120 via a first hinge line 122. Thus, the lid flap 150 may be pivoted toward the inside or outside of the first panel 120 around the first hinge line 122, i.e., between an open position where the receiving portion 110 is opened and a closed position where the receiving portion 110 is closed. Further, the first bend line 121 extends up to a free end 151 of the lid flap 150 across the first hinge line 122. Thus, the lid flap 150 has two halves 150a, 150b that are divided by the first bend line 121. The two halves 150a, 150b may be moved toward or away from each other with respect to the first bend line 121. That is, the lid flap 150 may be folded around the first bend line 121.
The first hinge line 122 intersects the first bend line 121 between the edges 114, 115 of the first panel 120 (or between the common edges of the first panel 120 and the first and second side panels 140a, 140b). Further, the first hinge line 122 intersects the first bend line 121 at an acute angle in an inward direction of the first panel 120. That is, the first hinge line 122 is convex toward the inside of the first panel 120 in a V-shape. Since the first hinge line 122 extends at an acute angle in the inward direction, when a lateral force is applied to the first panel 120 and the first panel 120 is bent as protruding upward, the lid flap 150 can be pivoted toward the inside of the first panel 120, i.e., toward the inside of the receiving portion 110. Further, since the lid flap 150 is foldable around the first bend line 121, the lid flap 150 can be pivoted toward the inside of the receiving portion 110 while its two sections 150a, 150b approach each other. Through the aforementioned pivoting and folding actions, the lid flap 150 opens the mouth portion 112 of the receiving portion 112. In the illustrated embodiment, the first hinge line 122 extends in the shape of a straight line. Alternatively, the first hinge line 122 may extend in the shape of a curved line.
The package 100 includes a first engagement flap 170 for maintaining the lid flap 150 to the position where the receiving portion 110 is closed. The first engagement flap 170 is integrally formed to the longitudinal end or front end of the second panel 130 via a fold line 132. The fold line 132 of the first engagement panel 170 is located more outwardly than the first hinge line 122 of the lid flap 150. The first engagement flap 170 is folded toward the first panel 120, i.e., toward the inside of the receiving portion 110. The second bend line 131 of the second panel 130 extends up to a free end 171 of the first engagement flap 170 across the fold line 132. Thus, the first engagement flap 170 is foldable around the second bend line 131. As shown in
A hanging portion 190 for use in hanging the package 100 on a display shelf or a wall surface for displaying the package 100 is provided in the package 100. In this embodiment, the hanging portion 190 includes a hanging hole 173, which is perforated in the first engagement flap 170, and a hanging hole 134, which is perforated in the second panel 130. When the first engagement flap 170 is folded onto the second panel 130, the hanging hole 173 and the hanging hole 134 are aligned with each other. The package 100 may be vertically hung by a peg, which is provided on a display shelf or a wall surface and passes through the hanging holes 134, 173. The hanging holes 134, 173 may have various shapes such as a circle, oval, rectangle, diamond, etc.
The lid flap 150 engages the free end 171 of the first engagement flap 170 at its free end 151, thereby closing the mouth portion 112 of the receiving portion 110.
In the closed position of the receiving portion 110, the free end 151 of the lid flap 150 engages the free end 171 of the first engagement flap 170, allowing the lid flap 150 to be maintained in the closed position. In this embodiment, the lid flap 150 has a pair of engagement tabs 152, which engage the free end 171 of the first engagement flap 170, at the free end 151. The engagement tab 152 extends from the free end 151 of the lid flap 150 and is integrally formed to the free end 151 of the lid flap 150 via a fold line 155. In the illustrated embodiment, the engagement tab 152 has a rectangular shape. Alternatively, the engagement tab 152 may have a semi-circular, semi-oval or polygonal shape.
In the closed position of the receiving portion 110, the engagement tab 152 of the lid flap 150 intervenes between the free end 171 of the first engagement flap 170 and the inner surface of the second panel 130, thereby engaging the free end 171. Specifically, a fixed end 153 of the engagement tab 152 engages the free end 171 of the first engagement flap 170 and a body 154 of the engagement tab 152 intervenes between the first engagement flap 170 and the second panel 130 (see
Further, to fix the lid flap 150 in the closed position, a pair of engagement notches 172 are provided at the free end 171 of the first engagement flap 170. When the lid flap 150 is pivoted from the open position of the receiving portion 110 to the closed position, the fixed end 153 of the engagement tab 152 is fitted to the engagement notch 172 along the engagement notch 172. In the closed position of the receiving portion 110, the fixed end 153 of the engagement tab 152 is fitted to the engagement notch 172 and the body 154 of the engagement tab 152 intervenes between the second panel 130 and the first engagement flap 170. Further, the free end 151 of the lid flap 150 is situated more outwardly than the free end 171 of the first engagement flap 170. When the lid flap 150 is in the closed position, one end of the wiper blade 10, 20, which is received in the receiving portion 110, may contact the lid flap 150 and then apply a force to the lid flap 150 in a direction perpendicular to the lid flap 150. Then, the lid flap 150 may be pivoted toward the outside of the package 100 while pushing the first engagement flap 170 outward. However, a portion of the first engagement flap 170, which is between the free end 151 of the lid flap 150 and the free end 171 of the first engagement flap 170, is situated more inwardly than the free end 151 of the lid flap 150. Thus, the lid flap 150 cannot be pivoted outwardly and is maintained in the closed position.
As shown by arrows F in
To pivot the lid flap 150 from the open position of the receiving portion 110 from the closed position, the first and second side panels 140a, 140b are released from the pressure applied thereto. Then, the package 100, which has constricted in the lateral direction, reverts to its original condition. At that point, the first panel 120 is bent in a direction reverse to that at which the first and second side panels are pressed. In addition to the first panel 120 being bent in the reverse direction, the lid flap 150 is pivoted to the closed position of the receiving portion 110 while the engagement tab 152 is inserted in between the first engagement flap 170 and the second panel 130.
Referring to
The bottom flap 160 is integrally formed to the longitudinally opposite end or the rear end of the first panel 120 via a second hinge line 123. The first bend line 121 extends up to a free end 161 of the bottom flap 160 across the second hinge line 123. Thus, the bottom flap 160 is foldable around the first bend line 121 and is pivotable with respect to the second hinge line 123 toward the inside of the receiving portion 110. Similar to the lid flap 150, the bottom flap 160 has a hexagonal shape.
The second hinge line 123 intersects the first bend line 121 between the edges 114, 115 of the first panel 120 (or between the common edges of the first panel 120 and the first and second side panels 140a, 140b). Further, the second hinge line 123 intersects the first bend line 121 at an acute angle in an inward direction of the first panel 120. That is, the second hinge line 123 is convex toward the inside of the first panel 120 in a V-shape. Thus, when a force in the lateral direction is applied to the first panel 120 in the vicinity of the bottom portion 113 of the receiving portion 110 and the first panel 120 is bent thereby, the bottom flap 160 may be pivoted toward the inside of the receiving portion 110. In the illustrated embodiment, the second hinge line 123 extends in the shape of a straight line. Alternatively, the second hinge line 123 may extend in the shape of a curved line.
The second engagement flap 180 is integrally formed to the longitudinally opposite end or rear end of the second panel 130 via a fold line 133. The second engagement flap 180 is folded toward the first panel 120, i.e., toward the inside of the receiving portion 110. The second bend line 131 of the second panel 130 extends up to a free end 181 of the second engagement flap 180 across the fold line 133. As shown in
The bottom flap 160 is fixed through engagement between its free end 161 and the free end 181 of the second engagement flap 180. The bottom flap 160 has, at its free end 161, a pair of engagement tabs 162 that engages the free end 181 of the second engagement flap 180. The engagement tab 162 extends from the free end 161 of the bottom flap 160. The engagement tab 162 is folded in a direction opposite to the folded direction of the bottom flap 160 around a fold line 165 located at a fixed end 163 of the engagement tab 162.
Further, to fix the bottom flap 160, a pair of engagement notches 182 are provided at the free end 181 of the second engagement flap 180. Referring to
To pivot the lid flap 150 to the open position, the first panel 120 may be bent by applying a force to the first and second side panels 140a, 140b at the vicinity of the mouth portion 112. However, the bending of the first panel 120 does not extend down to the bottom portion 113. Further, the lid flap 150 is engaged with the first engagement flap 170 in the closed position of the receiving portion 110 and is therefore maintained in the closed position unless the lateral force is applied to the first panel 120. When the lid flap 150 is in the closed position or at the vicinity of the closed position, the halves 150a, 150b of the lid flap 150 are folded in an inwardly convex manner around the first bend line 121 and the first bend line 121 within the lid flap 150 is situated approximately perpendicular to the first panel 120 and the second panel 130. Thus, when a force is applied from the first panel 120 toward the second panel 130 or vice versa, i.e., when a load is applied to the package 100 in a perpendicular direction, the first bend line 121 and the halves 150a, 150b folded around the first bend line 121 resist the perpendicular load. This allows the mouth portion 112 of the receiving portion 110 to have high structural rigidity. Further, when the bottom flap 160 is engaged with the second engagement flap 180, the halves 160a, 160b of the bottom flap 160 are folded in an inwardly convex manner. Thus, the first bend line 121 within the bottom flap 160 and the halves 160a, 160b of the bottom flap 160 allow the bottom portion 113 of the receiving portion 110 to have high structural rigidity. Accordingly, the mouth portion 112 and the bottom portion 113 of the package 100 have a high structural rigidity. By way of example, as shown in
The bend lines, the hinge lines and the fold lines described above may comprise indentations, scores, creases, perforations and the like formed in the package sheet 100′. By way of another example, the aforementioned lines may be formed by squeezing the package sheet 100′ in its thickness direction, for example, by stamping or indenting the package sheet 100′. Further, the aforementioned lines may be formed when manufacturing the package sheet 100′ from a raw sheet material, or after cutting or punching the package sheet 100′ from a raw sheet material.
Examples of assembling the package 100 will be described with reference to
The package sheet 100′ shown in
Next, as shown in
Next, as shown in
The assembly of the bottom portion 113 of the receiving portion 110 may be performed in a manner similar to the above-described exemplary assembly of the mouth portion 112. When opening the closed bottom portion 113, the first and second side panels 140a, 140b may be pressed toward the receiving portion 110 at the vicinity of the bottom portion 113. Then, the bottom flap 160 is pivoted from the second engagement flap 180 toward the inside of the receiving portion 110 and the engagement tab 162 of the bottom flap 160 is separated from the second engagement flap 180, thereby opening the bottom portion 113.
In the foregoing embodiments, the unitary package sheet 100′ is provided with all of the first panel 120, the second panel 130, 230 and the first and second side panels 140a, 140b. In other embodiments, each of the panels may be made individually and associated panels may be bonded together along their corresponding edges.
In the foregoing embodiments, the second panel 130, 230 has the hanging hole 134 and the first engagement flap 170 has the hanging hole 173. Another embodiment may include the second engagement flap 180 with the hanging hole and the second panel 130, 230 with the hanging hole corresponding to the hanging hole of the second engagement flap 180. The package in this example may be used in such a manner that the bottom flap 160 serves as the mouth portion of the receiving portion, since the bottom flap 160 is openable and closable like the lid flap 150.
In the foregoing embodiments, the engagement flaps for fixing the lid flap 150 and the bottom flap 160 are integrated with the longitudinal ends of the second panel 130, 230. In other embodiments, the engagement flaps may be made individually and attached to the longitudinal ends of the second panel 130, 230.
The package 100, 200 according to the embodiments disclosed herein has the mouth portion 112 that is openable through pressure in the lateral direction. Thus, the user or consumer can open the mouth portion 112 of the package by pressing the mouth portion 112 in the lateral direction. Further, the package 100, 200 according to the embodiments has the bottom portion 113 which is prevented from being pivoted through the engagement configuration. Thus, even if the package falls down or external impact is applied to the package, the wiper blade 10, 20 received in the package cannot fall out of the package. Further, the package 100, 200 according to the embodiments has the mouth portion 112 and the bottom portion 113 which resist a perpendicular load.
