Description

  The present invention relates to a blow molded standing thin container suitable for replacing a pouch composed of a synthetic resin film or a metal film, and is poured into the mouth of a container to be refilled when the contents are poured out. The part is inserted and efficient refilling is performed.

Deferred type containers that contain shampoo, rinse, liquid soap, cosmetics, etc. are generally equipped with a dispenser that allows the appropriate amount of content to be dispensed, and such containers are replenished with the contents. In order to reduce the constituent materials as much as possible, a thin-walled blow bottle made of a synthetic resin film or a metal film and a synthetic resin (for example, stretched polypropylene resin) is used as a refill container (for example, a patent). Reference 1 and Patent Reference 2).

  By the way, among the conventional refill containers, the pouch is widely used as a container for refills because the volume of the container can be reduced and the manufacturing cost can be reduced and the materials used can be reduced. Since the container itself is not stretched, it is impossible to insert the pouring part into the mouth of the container to be refilled, and there is a disadvantage that the contents spill out during refilling.

  In this respect, the blow-molded bottle has an advantage suitable for a refill container because the container itself has tension and can be inserted into the mouth part of the container to be replaced even though it is thinned. If the size is larger than the size of the mouth of the container to be refilled, it is impossible to insert it into the mouth, so there is a concern that the contents will spill out during refilling, as with a pouch. Due to the appearance of the bottle, it has a sense of being expensive, and remains unsatisfactory in appealing to consumers for sales promotion compared to containers such as pouches.

  In addition, as for the pouch, an attempt has been made to assemble a hard pouring pipe in the pouring portion and to efficiently pour the contents through the pouring pipe. However, such a pouch has an increased number of components. In addition, since the addition of the manufacturing process is indispensable, there is a disadvantage that causes an increase in manufacturing cost, and the advantage inherent to the pouch may be impaired.

  An object of the present invention is to propose a novel blow-molded standing thin-walled container that can stably pour the contents into a container to be refilled while taking advantage of the merits of the pouch and the blow-molded bottle.

  The present invention provides a thin fuselage wall part that forms a filling space for the contents and allows the opposing side walls to adhere to each other to reduce the filling space, and a lower end of the fuselage wall part. Connected to the bottom wall of the thin wall to stand up the body wall with or without the contents, and the body wall or the bottom wall part is integrally projected to open the tip to form a content pouring path A blow-molded standing thin-walled container including a thin-walled pouring portion and a filling portion for supplying contents to the filling space of the fuselage wall portion at an upper portion of the fuselage wall portion, It is a blow molded standing thin-walled container suitable for substituting for a pouch, characterized by comprising segments that taper sequentially toward the tip so as to have different diameters.

  In the pouring part, a flow path pipe that extends from the tip of the pouring part toward the filling space and replaces the air in the container when pouring the contents can be disposed adjacent to the pouring part. It can be arranged in series in a tapered staircase sequentially toward the tip.

  By selectively separating the segment of the conduit body according to the size of the mouth of the container to be refilled, the pouring part can be inserted into the mouth of the container to be refilled and the contents will not spill out. .

  Hereinafter, the present invention will be described more specifically with reference to the drawings.

  1 (a) and 1 (b) show an embodiment of a container according to the present invention. In FIG. 1, reference numeral 1 denotes a filling space for contents, and the opposing side walls are brought into close contact with each other to fill the container. A thin-walled body wall portion 2 for reducing the space is a thin-walled bottom wall portion that is integrally connected to the lower end of the body wall portion and stands up regardless of the presence or absence of contents.

  Also, 3 is a thin-walled pouring portion that integrally protrudes from the upper end corner of the body wall portion 1 and opens its tip by cutting with a scissors to form a content pouring path, and 4 is an upper portion of the body wall portion 1. The filling portion is provided adjacent to the pouring portion 3 and supplies the contents to the filling space of the body wall portion 1, and the filling portion 4 has its open end sealed by heat fusion or the like after filling the contents. It can be sealed.

  Further, 5 is a valley formed between the pouring part 3 and the filling part 4, and 6 is an air displacement which is arranged adjacent to the upper part of the pouring part 3 and extends from the tip of the pouring part 3 toward the filling space. It is a channel tube.

  The pouring part 3 has segments 3a and 3b which have different diameters and are arranged in series in a tapering step-like manner toward the tip of the pouring part 3, and the size of the mouth of the container to be refilled Accordingly, the aperture size of the extraction portion 3 can be changed by selecting and cutting one of the boundaries A and B of the segments 3a and 3b.

  When the air replacement flow path pipe 6 is provided along the extraction part 3, the flow path pipe 6 adopts a shape that is symmetrical with the extraction part 3 as shown in the figure.

  The container according to the present invention is manufactured by blow molding a synthetic resin such as polyethylene / polypropylene or polyethylene terephthalate, and the wall thickness is about 0.05 to 0.5 mm in order to enable compaction by folding. It is preferable that

  FIG. 2 shows another embodiment of the container according to the present invention. In FIG. 1, the pouring part 3 is shown as an example in which the pouring part 3 protrudes integrally from the upper end corner of the body wall part 1, but the pouring part 3 protrudes from the bottom wall part 2 when pouring and the trunk when standing. It may be a pop-up type that can be depressed toward the inside of the wall portion 1, and the formation position of the extraction portion 3 can be variously changed according to the application.

  The container has a structure composed of a single resin, a structure in which two or more kinds of resins are laminated, and is composed of two or more kinds of resins including a barrier layer such as an ethylene vinyl alcohol copolymer or nylon. A multilayer structure is applicable and is not limited in this respect. Moreover, although not shown in figure, it is possible to form a concave or convex line about the bottom wall part 2, and this makes it easy to fold the container.

  Moreover, although the extraction | pouring part 3 showed as an example the case where two segments 3a and 3b are arrange | positioned, the number can be increased / decreased as needed. Furthermore, although not shown, it is also possible to adopt a segment that tapers toward the tip instead of a stepped segment.

  The volume can be reduced by folding the container in the same way as a pouch, and the contents can be spilled because the size of the pouring part can be changed according to the size of the mouth of the container to be refilled. It can be used for a wide range of applications as a refill container.

It is the figure which showed embodiment of this invention, (a) is a front view, (b) is a side view. It is the figure which showed other embodiment of this invention.
