Description

  The present invention relates to a synthetic resin bag with a handle.

A handle member having a shape in which a laterally U-shaped leg plate is projected forward as a pair of left and right sides from the left and right sides of the standing rectangular handle plate is provided, and the pair of leg plates is formed at the rear portion of the rod body. A synthetic resin basket with a handle embedded in an outer wall surface of a recess by insert molding is known (Patent Document 1).
JP 2000-16434 A

  Synthetic resin bottles such as those described above increase in weight in the liquid-filled state as the capacity increases, and therefore the burden on the handle also increases and is easily detached from the synthetic resin bottle, so that the hook and the handle member are connected to each other. It is necessary to be able to perform more reliably than in the past.

  The present invention makes it possible to achieve such an object.

As a first means, a pair of left and right lateral U-shaped leg plates 12 are projected forward from both left and right sides of the handle plate 11 to form a handle member 10, and the pair of leg plates 12 are formed at the rear of the rod body. In the synthetic resin cage with a handle embedded in the wall surface of the recess 4 by insert molding, the upper surface of the front overhanging portion above each leg plate 12 is formed in several stepped portions 15 respectively, and the lower surface of the front overhanging portion below the leg plate 12 Were formed in the stair-like portion 15 having several reverse stair-like shapes.

As a second means, the stepped portion 15 having the first means and formed in the front overhanging portion above each leg plate 12 is formed so that the handle plate 11 side is low and the leg plate 12 front side is high. The stepped portion 15 having an inverted staircase shape formed in the forward projecting portion below each leg plate 12 was formed so that the handle plate 11 side was high and the front side of the leg plate 12 was low .

As a third means, the first and second means are provided, front flanges 13 are provided at both upper and lower ends of the handle plate 11, and both the upper and lower ends of the leg plate 12 are connected to the front surfaces of both ends of the upper and lower front flanges. An engaging ridge 14 having a rear surface as a vertical surface and a front surface as a downwardly inclined surface is attached to the upper surface of the upper forward flange 13; the lower surface of the lower front flange 13 is set as a vertical surface; An engaging ridge 14 having a front inclined surface inclined upward is provided .

  As can be understood from the drawings, the upper and lower end surfaces of the handle plate 11, the front surfaces of the upper and lower portions of the handle plate between the two leg plates, the outer surface excluding the inner surfaces of the two leg plates, and the left and right both sides The surface and the entire surface of the engaging projection are all covered and embedded in the wall surface of the heel recess by insert molding. Also, if the heel is accidentally dropped, the heel is compressed and the handle member in the recess is However, in the present invention, since the upper and lower surfaces of the front projecting portion above and below the leg plate are formed in the stepped portion 15, the pressing force from above and below these stepped portions is grasped. The force can be changed to a member compression force, and thus the handle member pushing force can be reduced.

  According to the second aspect, in addition to the effect described in the first aspect, each standing surface of the stepped portion prevents the pull-out of the handle member, thereby increasing the fixing force of the handle member in the recess. I can do it.

  According to the third aspect, in addition to the effect of the first or second aspect, the engaging protrusion 14 attached to both the forward flanges 13 at the upper and lower ends of the handle plate has a rear surface as a vertical surface. As with the standing surfaces of the stepped portion 15, the handle member rearward pushing force is prevented.

  First, the first embodiment shown in FIGS. 1 to 3 will be described. Reference numeral 1 denotes a synthetic resin ridge formed by biaxial stretching, and the mouth and neck portion is erected from the upper end of the trunk portion 2 through the shoulder portion. The cap 3 is screwed.

  As shown in FIG. 2, a recess 4 is formed at the rear of the barrel 1 so that the rear surface and the left and right sides are open. A handle member 10 shown in FIG. 3 is fitted into the recess by insert molding.

  The handle member 10 is formed by projecting a pair of left and right lateral U-shaped leg plates 12 from the left and right sides of an upright rectangular handle plate 11 so as to protrude forward. 13 is protruded forward, and the upper and lower ends of the leg plate 12 are connected to the left and right ends of the upper and lower front flanges 13.

  The upper and lower front flanges 13 are provided with engaging ridges 14 having a triangular cross section with the rear surface as a vertical surface and the front surface as an inclined surface. In addition, the upper and lower surfaces of the front projecting portions above and below the leg plate 12 are formed in several steps 15. The upper step-like portion is provided so as to descend one step from the rear, that is, from the handle plate side, and the lower step-like portion 15 is formed in a reverse step shape that rises one step from the handle side to the front.

  Further, an engaging protrusion 16 is provided vertically on the front end of the upper and lower stepped portions and on the opposite surface side of the lower or upper leg plate portion. Further, the leg plate portion between the upper and lower stepped portions is provided with an enlarged diameter portion 17 extending to the opposite side of the both leg plates with an appropriate gap in the vertical direction, and a plurality of lateral grooves 18 are provided on the extended portion of the enlarged diameter portion. Are drilled with a vertical gap.

  In the state where the leg plate 12 is embedded in the heel recess 4, the upper surface or the lower surface and the front surface of the upper and lower front flanges, and the outer surface and the left and right side surfaces of each leg plate including the stepped portion 15 are all covered with the heel recess forming wall 5. The member 10 is securely fixed to the rod 1.

  FIGS. 4 and 5 show a second embodiment, in which the stepped portion 15 described above is provided with a lower handle plate side and a higher leg plate front side. By doing so, each standing surface 15a of the stepped portion 15 faces rearward, and thus each standing surface prevents the pushing even if the handle member 10 is pushed backward.

  In addition, about the same part as 1st Embodiment, description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  It is the same as in the case of the first embodiment that the outer surface of the leg plate, the left and right side surfaces, etc. are covered with the recess forming wall surface by the leg insert molding into the heel recess 4.

It is a side view which shows a part of the present invention as a longitudinal section. FIG. 1 is a plan view showing a part of FIG. It is a perspective view of the handle member used for FIG. It is a side view which shows a part of this invention cage | basket shown in 2nd Embodiment as a longitudinal section. 4 is a perspective view of the handle member used in FIG.
