A schematic enlarged cross-sectional view of a bent portion in a state in which the upper opening is largely opened. The wrap film device 1 includes a case body 3 made of cardboard, a case 2 that can open and close the cover 4 made of cardboard of the upper opening 38, and a roll 5 for holding the wrap film in the case 2 and The cutting blade 20 that cuts the wrap film 31 that is pulled out from the casing 2 is cut.

如第1圖及第5圖所示，盒本體3，具有：盒前壁12、後壁14及底壁13和相對向的兩個端壁15。盒本體3的上部開口38是被由盒前壁12及後壁和相對向的兩個端壁15的各上邊包圍著。蓋體4，具有：經由折彎部43連接在後壁14上邊的頂板17；及當蓋體4位於蓋著的位置時，從頂板17朝盒前壁12平行垂下的蓋前壁18；和兩個蓋端壁19。切斷刀20是沿著蓋前壁18的下邊配置有刀尖21。上述折彎部43是在與端壁15平行的截面藉由模壓在上述盒體2的外側形成有凸部(第5圖431)在盒體的內側形成有凹部(第5圖432)。As shown in FIGS. 1 and 5, the cartridge body 3 has a cartridge front wall 12, a rear wall 14 and a bottom wall 13, and opposite end walls 15. The upper opening 38 of the cartridge body 3 is surrounded by the upper edges of the front wall 12 and the rear wall of the box and the opposite end walls 15. The cover body 4 has: a top plate 17 connected to the upper side of the rear wall 14 via the bent portion 43; and a cover front wall 18 which is suspended from the top plate 17 toward the front wall 12 of the case when the cover body 4 is in the closed position; Two cover end walls 19. The cutting blade 20 is provided with a blade edge 21 along the lower side of the cover front wall 18. The bent portion 43 has a convex portion formed on the outer side of the casing 2 by molding in a cross section parallel to the end wall 15 (Fig. 5 431), and a concave portion is formed inside the casing (Fig. 432).
第1圖及第3圖將蓋體4轉動到折彎部43的附近呈現上部開口38開口的狀態。於此狀態，以人手將導引帶35拉出的方式，從保鮮膜的滾筒5將保鮮膜31的端緣32朝盒本體外拉出，接著，如第2圖所示，以人手61、62朝盒體2外拉出所要的長度的保鮮膜31。當保鮮膜31朝盒體2外僅被拉出所要的長度後，如第4圖所示，朝上部開口38蓋起的位置轉動蓋體4，讓沿著蓋前壁18下邊安裝的切斷刀20位於盒前壁12的前方，以切斷刀20的刀尖21抵在位於保鮮膜31盒前壁12附近的部分切斷。被切離的保鮮膜使用在食品等所需的包裝。刀尖21是在蓋前壁18下邊的中央部附近具有頂點22的V字形。In the first and third figures, the lid body 4 is rotated to the vicinity of the bent portion 43, and the upper opening 38 is opened. In this state, the end edge 32 of the wrap film 31 is pulled out from the drum 5 of the wrap film toward the outside of the case by the hand pulling the guide tape 35, and then, as shown in FIG. 2, the human hand 61, 62 The plastic wrap 31 of the desired length is pulled out toward the casing 2. When the wrap film 31 is only pulled out to the desired length outside the casing 2, as shown in Fig. 4, the lid body 4 is rotated toward the position where the upper opening 38 is closed, and the cutting is performed along the lower side of the front wall 18 of the lid. The knife 20 is located in front of the front wall 12 of the cartridge, and the cutting edge 21 of the cutting blade 20 is cut against a portion located near the front wall 12 of the wrap film 31. The chopped plastic wrap is used in a package such as a food. The blade edge 21 is a V-shape having a vertex 22 in the vicinity of the center portion of the lower side of the cover front wall 18.
第3圖是沿著第1圖的保鮮膜裝製的C－C線的放大剖視圖。由於保鮮膜的端緣32是由黏貼在該端緣的導引帶拉出，所以，蓋體4僅朝折彎部42的附近轉動角度F(第3圖)打開盒體2的上部開口38。即以人手捏著導引帶35拉出的使用開始時，必須將上部開口38大幅地打開，頂板17是在折彎部43附近以人手轉動到越過後壁14的延長面16，而在頂板17與後壁的延長面16之間形成角度F。然而，由於蓋體4的折彎部43是具有彈性的硬紙板製的，所以會朝該轉動的相反方向，即產生將蓋體4朝關閉方向僅轉動角度R(第3圖)的恢復力。於以往的保鮮膜裝置中，因該恢復力大，所以蓋體4會轉動到蓋住上部開口38，使切斷刀20與人手而接觸造成人手疼痛或受傷的可能性。本發明是藉由改良折彎部43的構造，使作用在蓋體4(頂板17)的恢復力縮小來解決這樣的間題。Fig. 3 is an enlarged cross-sectional view taken along line C-C of the wrap film of Fig. 1. Since the end edge 32 of the wrap film is pulled out by the guide tape adhered to the end edge, the cover body 4 opens the upper opening 38 of the casing 2 only by the rotation angle F (Fig. 3) toward the vicinity of the bent portion 42. . That is, when the use of the pulling of the guide tape 35 by the hand is started, the upper opening 38 must be opened largely, and the top plate 17 is rotated by the hand to the extended surface 16 of the rear wall 14 near the bent portion 43 while on the top plate. An angle F is formed between the 17 and the elongate face 16 of the rear wall. However, since the bent portion 43 of the cover 4 is made of elastic cardboard, the resilience of rotating the cover 4 to the closing direction by only the angle R (Fig. 3) is generated in the opposite direction of the rotation. . In the conventional wrap film device, since the restoring force is large, the lid body 4 is rotated to cover the upper opening 38, and the cutting blade 20 is brought into contact with a human hand to cause pain or injury to the human hand. The present invention solves such a problem by improving the structure of the bent portion 43 and reducing the restoring force acting on the lid body 4 (the top plate 17).
第5圖表示誇大構成盒體硬紙板的厚度的盒體2的剖視圖，且是使蓋體4越過後壁14的延長面16僅朝折彎物43的附近轉動角度F，將上部開口38大幅打開後的狀態的放大剖視圖。如第5圖所示，為後壁14與頂板17的連設部之折彎部43是於與端壁15第1圖平行的截面(與第5的紙面平行的截面)，在盒體2的外側被模壓而形成具有凸部431的構造，即具有被模壓而形成朝內側突出的構造。盒本體3或蓋體4的其他折彎部41、42、44是在盒體2的內側被模壓而形成具有凸部411、421、441的構造，即具有被模壓而形成朝內側突出的構造。折彎部43是在盒體內側具有凹部432，其他折彎部41、42、44是在盒體外側具有凹部412、422、442。Fig. 5 is a cross-sectional view showing the casing 2 exaggerating the thickness of the cardboard body, and the extension surface 16 of the cover 4 over the rear wall 14 is rotated only toward the vicinity of the bend 43 by an angle F, and the upper opening 38 is greatly enlarged. An enlarged cross-sectional view of the state after opening. As shown in Fig. 5, the bent portion 43 which is the connecting portion between the rear wall 14 and the top plate 17 is a cross section parallel to the first drawing of the end wall 15 (a cross section parallel to the fifth paper surface), in the casing 2 The outer side is molded to have a structure having a convex portion 431, that is, a structure that is molded to protrude inward. The other bent portions 41, 42, 44 of the cartridge body 3 or the lid body 4 are molded on the inner side of the casing 2 to have a structure having convex portions 411, 421, and 441, that is, a structure that is molded to protrude inwardly. . The bent portion 43 has a concave portion 432 inside the casing, and the other bent portions 41, 42, 44 have concave portions 412, 422, and 442 on the outer side of the casing.
於第5圖的實施例中，折彎部43，具有：在盒體2的外側被模壓而形成具有凸部431的構造，在盒體2內側被模壓而形成具有凹部432的構造。藉此構造，當蓋體4的頂板17朝打開上部開口38的方向越過後壁14的延長面16僅轉動角度F時，會在折彎部43產生塑性變形。藉此，藉由折彎部43的彈性恢復力，可從被轉動的位置朝關閉上部開口38的方向恢復的角度R為90°以下，最好是70°以下，更好的是45°以下。以恢復力轉動的角度R愈小，越能減少切斷刀20與人手接觸造成人手疼痛或受傷的危險。In the embodiment of Fig. 5, the bent portion 43 has a structure in which the convex portion 431 is formed by being molded on the outer side of the casing 2, and is molded inside the casing 2 to have a structure having the concave portion 432. With this configuration, when the top plate 17 of the lid body 4 is rotated by the angle F beyond the extension surface 16 of the rear wall 14 in the direction of opening the upper opening 38, plastic deformation occurs in the bent portion 43. Thereby, the angle R which can be recovered from the rotated position toward the direction in which the upper opening 38 is closed by the elastic restoring force of the bent portion 43 is 90 or less, preferably 70 or less, more preferably 45 or less. . The smaller the angle R which is rotated by the restoring force, the less the risk of pain or injury to the hand caused by the contact of the cutting blade 20 with the human hand.
即，折彎部43是在盒體外側具有凸部431，並且在盒體內側具有凹部432，即朝向盒體外方突出(第5圖)。此構造中，當蓋體4的頂板17朝打開上部開口38的方向越過後壁14的延伸面16轉動角度F(第3圖)時，來自折彎部43之蓋4本身的恢復力，即從被轉動的位置朝關閉上部開口的方向轉動的角度R(第3圖)成為90°以下。因此，當蓋體4的頂板17朝打開上部開口38的方向越過後壁14的延長面16轉動超過角度F＝90°(第3圖)時，因折彎部43的彈性恢復力使頂板17返回停留在超過後壁14的延長面16的範圍內，所以不會接觸到刀尖21，而可安全地從上部開口38朝盒體外拉出導引帶35及被其所黏貼的保鮮膜的端緣32。That is, the bent portion 43 has the convex portion 431 on the outer side of the casing, and has a concave portion 432 inside the casing, that is, protrudes toward the outside of the casing (Fig. 5). In this configuration, when the top plate 17 of the cover 4 is rotated by an angle F (Fig. 3) over the extended surface 16 of the rear wall 14 in the direction of opening the upper opening 38, the restoring force of the cover 4 itself from the bent portion 43 is The angle R (Fig. 3) rotated from the rotated position toward the direction in which the upper opening is closed is 90 or less. Therefore, when the top plate 17 of the cover 4 is rotated over the extended surface 16 of the rear wall 14 in the direction of opening the upper opening 38 by more than the angle F = 90 (Fig. 3), the top plate 17 is elastically restored by the bending portion 43. The return stays beyond the extension surface 16 of the rear wall 14 so that the blade tip 21 is not touched, and the guide tape 35 and the wrap film adhered thereto can be safely pulled out from the upper opening 38 toward the outside of the casing. End edge 32.
折彎部43在盒體2外側具有凸部431，並且在內側具有凹部432，即因形成有朝向盒體外側突出的形狀，而使折彎部43的彈性恢復力變小的理由可能有以下原因。形成盒體之硬紙板的纖維對拉的阻力較大而不易產生塑性變形，而相對於此，卻具有容易對壓縮產生塑性變形的性質。第5圖所示的折彎部43是因蓋體4越過後壁14的延長面16轉動僅轉動第5圖的角度F，所以，盒體內側的凹部432會因拉力作用，本來塑性變形少卻產生大的恢復力，但因為是凹部所以本來就有壓縮力的作用。於此，由於會作用緩和壓縮力的拉力，所以不會產生大的恢復力，而且，盒體的外側的凸部431會因壓縮力產生塑性變形，而使彈性恢復力變小，結果可能因此使得折彎部43整體的彈性恢復力變小。The bent portion 43 has a convex portion 431 on the outer side of the casing 2, and has a concave portion 432 on the inner side, that is, a shape that protrudes toward the outer side of the casing, and the elastic restoring force of the bent portion 43 is reduced. the reason. The fiber forming the cardboard of the casing has a large resistance to pulling and is not easily plastically deformed, whereas on the other hand, it has a property of easily plastically deforming the compression. The bent portion 43 shown in Fig. 5 is rotated by the lid body 4 over the extended surface 16 of the rear wall 14 to rotate only the angle F of Fig. 5, so that the concave portion 432 on the inner side of the casing is slightly deformed by the tensile force. However, it has a large resilience, but because it is a recess, it has a compressive force. In this case, since the tensile force for relieving the compressive force acts, a large restoring force is not generated, and the convex portion 431 on the outer side of the casing is plastically deformed by the compressive force, and the elastic restoring force is reduced, and as a result, The elastic restoring force of the entire bent portion 43 is made small.
相對於此，折彎部在朝向盒體內側具有凸部，朝向盒體外側具有凹部的習知形狀(與第5圖後壁14和底壁13之間的折彎部42同形狀)的情況，盒體內側的凸部反抗拉力塑性變形少且由於本來就有拉力作用，所以會產生更大的恢復力。盒體外側的凹部受到壓縮力塑性變形雖彈性恢復力小，但折彎部的合計彈性恢復力會變大。因此，折彎部43如折彎部42朝向盒體內側突出時，因這樣的折彎部的恢復力使得頂板17的轉動角度R不會停留在越過後壁14的延長面16的範圍內，而使頂板17與刀尖21接近上部開口38，且在切斷刀20與人手接觸左右變大。On the other hand, the bent portion has a convex portion toward the inner side of the casing, and has a conventional shape having a concave portion on the outer side of the casing (the same shape as the bent portion 42 between the rear wall 14 and the bottom wall 13 of FIG. 5). The convex portion on the inner side of the box body has less plastic deformation against the tensile force and has a pulling force due to the original force, so that a greater restoring force is generated. The concave portion on the outer side of the casing is plastically deformed by the compressive force. Although the elastic restoring force is small, the total elastic restoring force of the bent portion is increased. Therefore, when the bent portion 43 protrudes toward the inner side of the casing, the bending angle R of the top plate 17 does not stay in the range of the extended surface 16 of the rear wall 14 due to the restoring force of the bent portion. Further, the top plate 17 and the blade edge 21 are brought close to the upper opening 38, and the cutting blade 20 is enlarged to the left and right in contact with the human hand.

Cutaway view. In Fig. 6, the first type plate 80 has a groove 81 and a ridge 82. The second type plate 90 has a ridge 91 that faces the groove 81 and a concave portion 92 that faces the ridge 82. The cardboard is placed between the second type plate 90 and the first type plate 80 and compressed by a predetermined compressive force, and the convex portions 421 and 431 and the concave portions 422 and 432 may be formed at predetermined positions of the cardboard. The first type plate 80 and the second type plate 90 may be disposed, for example, one on the other side or in a horizontal direction (the cardboard is in the vertical direction). The convex portion 431 and the concave portion 431 become the bent portion 43, and the convex portion 421 and the concave portion 422 become the bent portion 42. The rear wall 14 is formed between the bent portion 43 and the bent portion 42. The bent portions 41, 42, 44 other than the bent portion 43 between the lid body and the rear wall may be molded to have convex portions facing the inner side of the casing. It is also preferable to form all the bent portions of the casing in a single process before assembling the casing.
