Description

  The present invention relates to a thin-walled blow-molded container suitable for a container for storing a shampoo, a rinse replenisher or the like.

  In shampoos and rinses, when the liquid contained in the container is used up, the replenisher contained in the refill container can be purchased, and the replenisher can be transferred to a container that is always used and the original container can be reused. Has been done. A container for storing such a replenisher is generally formed thin because it is immediately discarded after the replenisher is transferred.

  Conventionally, such thin-wall containers for replenishers often use so-called pouch containers in which sheet-like resins are laminated from the left and right sides and welded in a predetermined shape.

JP 2001-171689 A

  However, since the pouch container is welded by abutting flat sheets parallel to each other, it is difficult to expand the center part of the container, the bottom part is not stable, and the pouring part is similarly formed by pasting together sheet-like resin. It was difficult to form a cylinder, and it was difficult to pour the content liquid.

  Further, the pouring part may be separately molded into a cylindrical shape with a resin or the like, and the cylindrical pouring part may be attached to the pouch container to serve as a pouring outlet. However, the manufacturing process is increased and labor and cost are increased.

  In addition, in the pouch container, a V-shaped cut or the like is provided in advance at the location to become the spout, and the tip portion is cut out from the cut to open the spout, but the cut portion is a flat surface. In some cases, the spout was tilted and inclined.

  In addition, the cut off tip cannot be placed on a table as it is because it is wet with the contents liquid, and immediately throws it away into a garbage container or transfers the replenisher while holding the cut tip in one hand. It had to be replaced and was not easy to use.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a thin-walled blow molded container that can solve the above-mentioned problems, can be easily opened, can be easily poured out, has a stable bottom, and is easy to use.

  The present invention relates to a thin-walled blow-molded container, which is provided with a cutout portion at the tip, a pipe barrel that cuts off the cutout portion and opens a spout, and a connecting piece that connects the cutout portion to a part of the container. Provided and formed integrally by blow molding.

  Further, the connecting piece for connecting the cut portion and the container is hollow, and when the content liquid is poured out from the spout, air is introduced into the container from the inside of the cut portion through the connecting piece.

  The connecting piece is provided with a bellows portion, and can be bent at the bellows portion, and the cutout portion can be arranged at an arbitrary position by the bellows portion.

  The connecting piece is bent and connected to the container so as to bypass the cut-off portion of the cut-out portion.

  The thin-walled blow-molded container of the present invention is easy to manufacture because it is integrally molded, and because it is blow-molded, the spout is formed into a cylindrical shape, and the cut portion is removed from the tip so that it can be easily opened and poured out. it can. In addition, since the cut-out part is connected to the container, it is possible to facilitate the pouring operation and reduce the labor of disposal.

  When the content liquid is poured out, air flows into the container through the hollow connecting piece, so that the content liquid can be poured out smoothly.

  The connecting piece is bent at the bellows part, and the cutout part can be arranged at a position where it does not come into contact with the content liquid poured out from the spout, so that the content liquid can be reliably poured out without interfering with the cutout part.

  Since the connecting piece is formed avoiding the cut off part of the cut-out part, it is easy to thread when cutting the cut-out part by hand, or the tools can be difficult to touch when cutting with scissors. Damage can be prevented.

  FIG. 2 shows an embodiment of a blow molded container according to the present invention.

  The blow-molded container 2 (hereinafter referred to as container 2) is a so-called thin-walled replenisher container that is molded using a blow molding machine, and extrudes the resin melted in the mold into a cylindrical parison. It is molded by blowing air inside the parison.

  The container 2 has a cylindrical shape as a whole, and has an extraction cylinder 6 at the top and a seal portion 4 which is heat-welded after the contents are stored, and is disposed on both sides of the container 2 before and after (left and right in FIG. 1). Further, a fold line 5 extending in the vertical direction is formed. Due to this broken line 5, the cross section of the container 2 is substantially a long hexagon.

  Further, the bottom of the container 2 is formed in a mountain shape with the center folded inward as shown in FIG. 4, and when the contents liquid is accommodated, both ends are expanded so that the container 2 is self-supporting.

  As shown in FIG. 4, the dispensing cylinder 6 has a substantially cylindrical shape, and a cut-out portion 8 is formed at the tip through a cut-out groove 10. The cut portion 8 is a flat cylindrical body, and is connected to the upper portion thereof so that the connecting pipe 12 as a connecting piece is curved so as to bypass the groove 10. Note that the dispensing cylinder 6 is not limited to a cylinder, and may be any shape as long as it is a cylinder, and the inner diameter may not be constant.

  The connecting tube 12 is a hollow tube, and is connected in a state where one connecting end communicates with the inside of the cutout portion 8 and the other connecting end communicates with the inside of the container 2. A bellows portion 13 is formed at an intermediate portion of the connecting pipe 12. The bellows portion 13 is bendable, and can hold the connecting tube 12 in a bent state. For example, as shown by a two-dot chain line in FIG. 1, the cutout portion 8 can be held in an arbitrary position.

  Next, the operation of the container 2 will be described.

  The container 2 contains, for example, a replenishing shampoo liquid and is used when replenishing the shampoo liquid to another container such as a pump-type container.

  To replenish the liquid, first, the cut portion 8 is threaded from the groove 10 or is cut using scissors (not shown). When the cutout portion 8 is cut off, a substantially circular spout 3 is formed at the tip of the spout cylinder 6.

  Even if the cut-out part 8 is cut off from the groove 10, it is connected to the container 2 by the connecting pipe 12, and the bellows part 13 is bent and arranged at a position away from the spout 3 as shown in FIG. In this way, the container 2 is tilted, and the content liquid is injected from the spout 3 into another container.

  Therefore, according to the container 2, since the connecting pipe 12 is curved, the cutout portion 8 can be easily threaded or separated from the dispensing cylinder 6 using scissors without damaging the connecting pipe 12, and the spout 3 is formed. It can be opened. Furthermore, since air is sent into the container 2 from the cut-out part 8 through the connecting pipe 12, the content liquid can be smoothly poured out from the spout 3. In addition, the cutout portion 8 can be disposed at an appropriate position without being held by hand, so that the content liquid being poured out does not come into contact with the cutout portion 8.

  When all of the content liquid has been poured out from the container 2, the container 2 is pushed from the left and right to be folded and discarded. Since the container 2 is formed thin, the amount of the resin to be discarded is small, and the container 2 can be discarded together with the cutout portion 8.

  In the above example, the connecting piece is hollow as the connecting pipe 12, but in the present invention, the connecting piece may be formed of a solid member. Moreover, the shape of the seal part 4 and the bottom part 14 is not restricted to the said example.
