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 used for refilling the mouth of a container to be refilled when the contents are poured out. It is intended to reliably prevent leakage and scattering of the contents by fitting the extraction portion of the container for storing the contents.

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 has no tension, it was impossible to fit the spout into the mouth of the container to be refilled, and there was a disadvantage that the contents spilled out during refilling.

  In this respect, the blow molded bottle has an advantage suitable for a refill container because the container itself has a tension and the pouring part can be inserted into the mouth of the container to be refilled even though it is thinned. Since a gap is formed between the mouth of the container to be refilled, particularly when the contents are powder, there is a problem of scattering through the gap.

  In addition, as for the pouch, although an attempt has been made to assemble a hard pouring pipe in the pouring part and refill the contents through the pouring pipe, such a pouch is an increase in the number of components and the manufacturing process. Since it is indispensable to add, 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.

A thin wall of the body wall that partitions the filling space for the contents and allows the opposing side walls to adhere to each other to reduce the volume of the filling space, and is integrally connected to the lower end of the body wall portion. A thin bottom wall portion that stands up with or without the contents, and a thin wall casting that protrudes integrally from the body wall portion or the bottom wall portion and opens the tip to form a content pouring path A blow molded standing thin-walled container comprising an exit part and a filling part for supplying contents to the filling space of the body wall part at the upper part of the body wall part,
A blow molded standing thin container suitable for substitution for a pouch, characterized in that the outer wall of the pouring part has a flange that seals the mouth part of the container to be refilled so as to seal the mouth part.

  The outer wall of the pouring part is provided with a flange integrated with it, and the tip of the pouring part is inserted into the mouth of the container to be refilled, and the flange is put on the protruding end of the mouth to pour out the mouth of the container. There is no gap between the parts, and the contents do not leak or scatter accidentally.

  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.

  Reference numeral 5 denotes a flange integrally provided on the outer wall of the pouring part 3. This flange 5 is fitted to the mouth end of the container to be refilled and seals the mouth of the container to prevent the contents from leaking out or scattering.

  In order to refill the contents, first, the tip of the pouring part 3 is cut along the A line with a scissors or the like. And as shown in FIG. 2, the front-end | tip of the extraction | pouring part 3 is inserted in the opening part 6 of the container which should be refilled, and the flange 5 is assigned to the protrusion end of this opening part 6. As shown in FIG.

  As a result, there is no gap between the mouth portion 6 and the dispensing portion 3 of the container, so that the contents do not leak or scatter. This structure is particularly effective when the contents to be refilled are powders, but the contents are not limited to powders and can be used for liquids.

  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. 3 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 ethylene pinyl alcohol copolymer or nylon. A multi-layer structure can be applied, and this point is not limited. 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.

  In addition, the flange 5 is shown as an example of a disk shape, but the shape is not particularly limited as long as the mouth of the container to be refilled can be reliably sealed.

  As with pouches, the volume can be reduced by folding the container, and the mouth of the container to be refilled can be securely sealed when the contents are poured out, so that the contents can be refilled without leaking or splashing. Can be used in a wide range of applications as a 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 the extraction | pouring situation of the contents. It is the figure which showed other embodiment of this invention.
