Description

  The present invention relates to a side breakage promoting portion formed along both side edges of a substantially rectangular sheet, a pair of waist cords formed by breaking the side breakage promoting portion, and two side breakage promoting portions. It is related with the simple apron provided with the main-body part for guarding dirt.

  For example, as shown in Patent Document 1, a conventional simple apron includes a main body portion, a pair of waist straps, and an opening at the top. And when wearing, after passing a neck through an opening part, a pair of torso straps are tied to a back, covering abdominal part from a chest with a main-body part. In a simple apron of the type as in Patent Document 1, since the torso string and the main body are not integrally formed at the time of manufacture, the torso string flutters in the manufacturing process, and it may be wound around the manufacturing apparatus and cause trouble. There is a problem that manufacturing efficiency falls. Moreover, since an opening is provided, there is also a problem that a punched piece punched out from the opening will come out as dust.

  There exists a simple apron like patent document 2 for solving such a problem. In the simple apron of Patent Document 2, a pair of perforations formed linearly along the upper edge of a substantially rectangular sheet, a pair of necklaces formed by breaking a pair of perforations, and a perforation And a main body part formed integrally with the neck string. Such a simple apron is usually manufactured by feeding a long sheet wound in a roll shape, continuously forming a perforation, and winding it again in a roll shape. In the simple apron as in Patent Document 2, since the neck string and the main body are integrally formed through the perforation at the time of manufacture, the neck string does not flutter in the manufacturing process. In addition, since the configuration is simple, manufacturing efficiency can be increased. In addition, there is no portion that needs to be punched, such as an opening, and no dust is generated on the punched piece.

Furthermore, the opening forming portion which is a cutting line segment is not formed at the time of manufacturing, and the opening forming portion does not flutter or get caught in a manufacturing apparatus in the manufacturing process, and can be efficiently manufactured. Furthermore, when the opening forming portion is formed, the breaking force is released along the arc of the upper fracture stopping portion, and the fracture can be prevented from proceeding before the end of the upper fracture promoting portion. For this reason, the breakage progresses unnecessarily to the main body, and the function of guarding the body, which is the original purpose of the main body, from being contaminated is not impaired. Therefore, a wearer can be reliably protected from dirt. Furthermore, the upper break stop portion can be configured such that punching such as an opening is not required. In addition, since the head is passed through the opening forming portion at the center of the upper portion and the pair of waist cords are tied and worn near the back, the simple apron can be firmly worn. Thereby, a wearer can be reliably guarded from dirt. Therefore, it is possible to provide a simple apron that can be efficiently manufactured and is easy to wear.

  According to the invention described in claim 2, since the opening forming portion is formed in an arc shape projecting downward, when the head is passed through the opening forming portion, the arc shape of the opening forming portion is Fits the line and is easy to wear.

According to the third aspect of the present invention, the side break stop portion is cut in an arc shape of 180 to 270 degrees from the direction in which the side break promotion portion is formed. Therefore, a sufficient gap can be opened in the arc. When the sheet is ruptured along the side rupture promoting portion, the side rupture stop portion effectively escapes the direction of rupture, so that the rupture does not spread linearly beyond the side rupture promoting portion.

According to the fourth aspect of the present invention, the upper break stop portion is cut into an arc of 180 to 270 degrees from the direction in which the upper break promotion portion is formed. Therefore, a sufficient gap can be formed in the arc. When the sheet is ruptured along the upper rupture promoting portion, the upper rupture stop portion effectively escapes the direction of rupture, so that the rupture does not extend linearly beyond the upper rupture promoting portion.

According to the invention of claim 5 , since the lower end central portion of the sheet includes a protruding portion that protrudes downward, and includes notch portions that are notched upward on both sides of the protruding portion. When worn, the wearer's leg is located in the notch, and the simple apron does not cling to the leg when walking.

According to the sixth aspect of the present invention, the side breakage accelerating portion and the side breakage accelerating portion that are formed along both side edges from the upper end to the substantially lower end of the substantially rectangular individual sheet are broken. A pair of body straps formed between the two side breakage promoting parts, a main body part for guarding dirt, an upper breakage promoting part formed in the upper center of the individual sheet, and an upper part An opening forming part formed by breaking the breakage promoting part, an arc-shaped upper breakage stopping part that stops the breakage at both ends of the upper breakage promoting part, and a straight side breakage promoting part directly at the end And an arcuate side portion of the individual sheet for stopping the breakage , and the waist strap is symmetrical, and the opening forming portion is formed of the substantially rectangular individual sheet.

Therefore, the torso strap is integrated with the main body at the time of manufacture, and the torso strap does not flutter in the manufacturing process or wrap around the manufacturing apparatus, and can be efficiently manufactured. Furthermore, when forming the opening forming portion, the upper break stopping portion that effectively escapes the direction of the break is a configuration that does not require punching of the opening or the like, so that the punched pieces discharged in the manufacturing process are mixed as foreign matter There is nothing to do. Therefore, the manufacturing method of the simple apron which can be manufactured efficiently can be provided. In addition, since a simple apron is manufactured by forming a side breakage promoting part, an upper breakage promoting part, and a separation promoting part on a long sheet wound in a roll shape, it can be efficiently produced. Further, since the long sheet on which the side breakage promoting portion, the upper breakage promoting portion, and the separation promoting portion are formed is wound again in a roll shape, a large number of simple aprons can be stored in a compact manner.

According to invention of Claim 7 , the side part breakage promotion part formed along the both-sides edge from the upper end of the substantially rectangular individual sheet | seat toward the substantially lower end direction, and a side part breakage promotion part are fractured | ruptured.

Therefore, the torso strap is integrated with the main body at the time of manufacture, and the torso strap does not flutter in the manufacturing process or wrap around the manufacturing apparatus, and can be efficiently manufactured. Furthermore, when forming the opening forming portion, the upper break stopping portion that effectively escapes the direction of the break is a configuration that does not require punching of the opening or the like, so that the punched pieces discharged in the manufacturing process are mixed as foreign matter There is nothing to do. Therefore, the manufacturing method of the simple apron which can be manufactured efficiently can be provided. In addition, since a simple apron is manufactured by forming a side breakage promoting part, an upper breakage promoting part, and a separation promoting part on a long sheet wound in a roll shape, it can be efficiently produced. Further, since the long sheet on which the side breakage promoting portion, the upper breakage promoting portion, and the separation promoting portion are formed is wound again in a roll shape, a large number of simple aprons can be stored in a compact manner.

  Also, after forming the side breakage promoting portion, the upper breakage promoting portion, and the separation promoting portion on the tube-like long sheet, one end of the tube-like long sheet is cut off, so an end cutting step is provided. Therefore, there is no need to provide a two-fold process for folding the long sheet in the longitudinal direction. Therefore, the manufacturing apparatus can be reduced in size.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of an example of a simple apron of the present invention. The simple apron 10 can be used for any work that may be contaminated, such as for medical use, cooking, and machine repair, and is intended to protect the wearer from dirt. The simple apron 10 is formed of a substantially rectangular sheet S made of a plastic film (in this example, L1 = 1200 mm, L2 = 710 mm, but is not limited to this), and is formed on both side edges SS of the sheet S. Parallel perforations (side breakage promoting portions) 11 and 11 are provided in a straight line. The perforation 11 is formed from the upper end SU of the sheet S to approximately the center. Between the left and right perforations 11 and 11 and the left and right side edges SS, respectively, trunk straps 12L and 12R are provided. The torso strings 12L and 12R have the same shape and are formed by breaking the perforations 11.

  A body portion 13 for guarding dirt is provided between the two perforations 11 and 11 and below the perforation 11. Further, an arc-shaped perforation (upper rupture promoting portion) 14 projecting downward is provided between the two perforations 11 and 11 and on the upper portion of the sheet S.

  At the end of the perforation 11, an arcuate cut portion (side break stop portion) 21 for stopping the progress of breakage is formed. As shown in FIG. 2A, the cutting portion 21 is a cutting line segment, and is cut into an arc shape by a predetermined angle α (α is about 180 to 270 degrees) from the direction in which the perforation 11 is formed. It becomes. Therefore, when the sheet S is ruptured along the perforation 11, the cut portion 21 escapes in the direction of the rupture, so that the break does not extend linearly beyond the perforation 11.

  In addition, arc-shaped cut portions (upper break stop portions) 22 for stopping the progress of breakage are formed at both ends of the perforation 14. As shown in FIG. 2B, the cutting portion 22 is a cutting line segment, and is cut into an arc shape by a predetermined angle β (β is about 180 to 270 degrees) from the direction in which the perforation 14 is formed. It becomes. Therefore, when the sheet S is ruptured along the perforation 14, the cut portion 22 escapes in the direction of the rupture, so that the break does not extend linearly beyond the perforation 14. The cutting part 22 is formed symmetrically on the left and right of the perforation 14.

  A center portion of the lower end SB of the sheet S is provided with a projecting portion 23 projecting downward in an arc shape, and on both sides of the projecting portion 23, a notch portion 24 that is notched in an arc shape upward. , 24.

  On the other hand, a center portion of the upper end SU of the sheet S is provided with a notch portion 26 that is cut out in an arc shape downward, and an overhang portion that protrudes in an arc shape upward on each side of the notch portion 26. 25, 25. In addition, the overhang | projection parts 25 and 25 and the notch parts 24 and 24 are formed symmetrically. In other words, the overhang portions 25 and 25 are formed so as to fit into the notches 24 and 24. Similarly, the overhang part 23 and the notch part 26 are formed symmetrically.

  Next, a method for wearing the simple apron 10 thus formed will be described. First, the left and right perforations 11 and 11 are broken from the upper end SU of the sheet S to form the trunk cords 12L and 12R (FIG. 3A). At this time, since the cut portion 21 is formed at the end of the perforation 11, the breaking force is released along the arc of the cut portion 21, and the break is linear before the end of the perforation 11. Does not progress.

  Next, the perforation 14 is broken toward both sides from the vicinity of the center of the perforation 14 to form an opening forming portion 14O (FIG. 3B). At this time, since the cut portions 22 are formed at both ends of the perforation 14, the breaking force is released along the arc of the cut portion 22, and the break does not proceed beyond the end of the perforation 14. Reference numerals 14 </ b> L and 14 </ b> L are cutting line segments of the opening forming portion 14 </ b> O formed by breaking the perforation 14.

  In this way, the simple apron 10 is formed. Next, the opening forming part 14O of the simple apron 10 is opened to form an opening, through which the opening forming part 14O is hung on the neck so that the main body part 13 covers the abdomen from the chest. Further, a pair of waist straps 12L and 12R are tied to the back side, and a simple apron 10 is worn. At this time, since the notches 24 and 24 are located near the thighs of both legs, the main body 13 does not cling to the legs when walking. Thus, when the wearer hangs his neck on the opening forming portion 14O and wears the simple apron 10, the lower end SB of the simple apron 10 is such that the lower end SB of the simple apron 10 It is desirable to be located in the vicinity.

  In this example, at the time of manufacturing, the opening forming portion 14O is formed by the perforation 14, and when the simple apron 10 is used, the perforation 14 is broken to form the cut line segment, but the present invention is limited to this. The opening forming part 14 may be cut at the time of manufacturing (the opening forming part 14 may be formed by opening at the time of manufacturing).

  In this example, the perforation 11 is provided downward from the upper end SU of the sheet S to form the pair of waist straps 12L and 12R. However, the present invention is not limited to this, and the lower end of the sheet S is not limited thereto. A pair of waist cords may be formed by providing a perforation (side breakage promoting portion) linearly from SB along both side edges SS of the sheet S upward. Further, the perforation 11 is not limited to being provided in parallel with the both side edges SS of the sheet S, and may be formed so that the body strap becomes thicker downward. If it does in this way, the main-body part 13 can respond to the constriction of waist vicinity, and wearability will improve further.

  Furthermore, in this example, the sheet S is made of a plastic film, but the present invention is not limited to this, and any material can be used. For example, paper, a nonwoven fabric, etc. may be sufficient and the laminate sheet of paper or a nonwoven fabric and a plastic film may be sufficient. Further, a material composed of two or more layers may be used. For example, the surface layer is composed of at least one selected from paper, natural or synthetic fiber woven or non-woven fabric, absorbent cotton, water absorbent polymer, sponge, etc. The layer may be made of a thermoplastic resin or rubber. Furthermore, in addition to the surface layer and the back layer of these configurations, a three-layer structure including an intermediate layer made of a water-absorbing polymer may be used.

  In addition, the perforation (upper rupture promoting portion) 14 is not limited to a shape projecting downward in an arc shape. For example, as shown in FIG. The eye (upper fracture promoting portion) 114 may be used. Of course, also in this case, it is preferable to provide the cut portions (upper fracture stop portions) 22 and 22 at both ends. In this example, the perforation 114 is broken to form an angular U-shaped opening forming portion. Therefore, the opening formation part of the shape substantially along the neck line can be formed, and the wearability is good.

  Moreover, as shown in FIG.4 (b), it is good also as a linear perforation (upper fracture | rupture promotion part) 214. FIG. In this example, the perforated line 214 is broken to form a linear opening forming portion. Although the wearability is inferior to the former two, the shape of the perforation 214 is straight, so that the manufacture is easy.

  Furthermore, as shown in FIG. 4C, perforations 30 and 30 may be formed downward from the notch portion 26 toward the perforation 14. The perforation 30 breaks at the perforation 30 when the main body 13 is pulled down after unwinding the torso straps 12L and 12R when the simple apron 10 is completely worn. The simple apron can be easily undressed.

  Further, the upper end SU and the lower end SB of the sheet S may be formed linearly without forming the overhang portions 23 and 25 and the notches 24 and 26.

  Next, the manufacturing method of the simple apron 10 is demonstrated using Fig.5 (a)-(d). First, as shown to Fig.5 (a), the long sheet | seat LS1 made from a plastic film is unwound from the original fabric roll RG (delivery process). At this time, the width of the long sheet LS1 is set to 2 W, and both side ends are set to E1 and E2, respectively. Next, in FIG. 5B, the fed long sheet LS1 is folded into two at the center in the longitudinal direction (that is, the center line C in the width direction of the long sheet LS1). At this time, the side ends E1 and E2 are aligned so as to be overlapped to form an end AW. In addition, a folded portion R is formed on the opposite side. Note that the width of the folded long sheet LS2 is W.

  Further, as shown in FIG. 5 (c), a long sheet LS2 folded in two is provided with a perforation (side breakage promoting portion) 11, a perforation (upper breakage promoting portion) 14, and a substantially rectangular shape later. A perforation (separation promoting portion) 35 for separating the individual sheets S is formed (a fracture promoting portion forming step). Since the perforation 11, the perforation 14, and the perforation 35 are simultaneously formed on the upper and lower sides of the long sheet LS2 that is overlapped in half, the waist straps 12L and 12R are formed symmetrically, and the opening forming portion 14O is It is formed symmetrically with respect to the center line in the width direction of the substantially rectangular individual sheet S (as will be described later, by breaking the perforation 35, the upper end SU of the sheet S (and the lower end of the sheet S) is formed. It is formed). In this state, as shown in FIG. 5 (d), the long sheet LS2 is wound into a roll shape to form a product roll RE (winding step). The product roll RE is packed in a box and shipped.

  When the simple apron 10 is used from the product roll RE manufactured in this way, as shown in FIG. 6, the lid L of the box B is raised and the tip of the product roll RE (that is, the product roll RE stored therein) Pull out the upper end SU) of the sheet S. When one sheet S is pulled out, the sheet is separated from the product roll RE along the perforation 35. Thereafter, the straps 12L and 12R are formed in the manner described above, the opening forming portion 14O is formed, and the simple apron 10 is formed.

The raw roll may be a tube-like long sheet instead of a sheet-like long sheet. In this case, as shown to Fig.7 (a), the tubular long sheet | seat TLS1 made from a plastic film is unwound from roll original fabric TRG (delivery process). At this time, the width of the tubular long sheet TLS1 is set to W, and both side ends are set to TE1 and TE2, respectively. Next, as shown in FIG. 7 (b), the tubular long sheet TLS1 has a perforation (side breakage promoting portion) 11 and a perforation (upper breakage promoting portion) 14, and a substantially rectangular individual later. A perforation (separation promoting portion) 35 for separating the sheet S is formed (a fracture promoting portion forming step). Accordingly, the waist straps 12L and 12R are simultaneously formed in the left and right sides of the overlapped tube-like long sheet TLS1, and the opening forming portion 14O is line-symmetric with respect to the center line in the width direction of the substantially rectangular individual sheet S. (As will be described later, the upper end SU of the sheet S (and the lower end SB of the sheet S) is formed by breaking the perforation 35). Then, the side end TE2 is cut along the longitudinal direction by the width Δd (end cutting step). Thereby, the tubular long sheet TLS1 becomes a long sheet TLS1 ′ having a width (2W−2Δd) folded at the side end TE1. In this state, as shown in FIG. 7 (c), the long sheet TLS1 ′ is wound into a roll shape to become a product roll RE ′ (winding step). The product roll RE ′ is shipped in a box by roll.

  Note that the method of using the product roll RE ′ is the same as the method of using the product roll RE shown in FIG.
