Abstract

<P>PROBLEM TO BE SOLVED: To propose a blow molding thin-walled container with which a pouch can be substituted and into which a content can be easily fed. <P>SOLUTION: A blow molding standing thin-walled container is equipped with a thin-walled barrel wall part (1) which divides and forms a filling space for the content and can reduce the volume of the filling space by bringing facing side walls into mutually tight contact with each other, a thin-walled bottom wall part (2) integrally connected to the lower end of the barrel wall part (1) and standing the barrel wall part (1) regardless of existence of the content, a thin-walled bung hole part (3) integrally projecting from either the barrel wall part (1) or the bottom wall part (2) and opening the apex to form a discharging path for the content, and a filling part (4) for feeding the content to the filling space of the barrel wall part (1) at the upper part of the barrel wall part (1). A nozzle (3a) inserted into the opening of the container to be repacked and an expanding part (3b) connecting mutually this nozzle (3a) with the barrel wall part (1) to form a flat space with a large diameter, are provided at the apex of the bung hole part (3). <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a blow molded standing thin container suitable for replacing a pouch made of a synthetic resin film or a metal film, and efficiently supplies the contents in the refill container to the container to be refilled. It is something to try.

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 is impossible to insert the spout into the mouth of the container to be refilled, and there is a disadvantage that the contents spill out during refilling.

  In this regard, blow molded bottles have an advantage that is suitable for refilling containers because the container itself has a certain amount of tension even though it is thinned, and the pouring part can be inserted into the mouth of the container to be refilled. The part protrudes in a certain direction with respect to the body of the container, and the tilting posture of the container is always limited.

  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 new blow-molded standing thin-walled container that can replace a pouch and that increases the degree of freedom of the container pouring posture.

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 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 the contents pouring path A blow-molded standing thin-walled container comprising: a thin-walled pouring portion, and a filling portion for supplying contents to the filling space of the body wall portion at the upper portion of the body wall portion;
The pouring part comprises a nozzle inserted into the mouth of a container to be refilled at the tip thereof, and a bulging part that connects the nozzle and the body wall part to form a flat large-diameter space. It is a blow molded standing thin container.

  It is possible to use the nozzle and the bulging part as a funnel when opening the container by configuring the nozzle to be inserted into the mouth of the container to be refilled and the bulging part that connects the nozzle and the body wall part to each other. This increases the degree of freedom of the refill container's pouring posture, making refilling work easier.

  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.

  Reference numeral 3 denotes a thin-walled pouring portion which 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. The pouring part 3 includes a nozzle 3a to be inserted into the mouth of a container to be refilled and a bulging part 3b that forms a flat large-diameter space that connects the nozzle 3a and the body wall part 1 to each other. A filling portion 4 is provided on the upper portion of the body wall portion 1 adjacent to the pouring portion 3 and supplies the contents to the filling space of the body wall portion 1. The filling portion 4 is filled with the contents. The open end can be sealed later by heat fusion or the like.

  In order to refill the contents, first, cut with a scissors or the like along the A line at the tip of the nozzle 3a and the B line and C line at the base of the bulging portion 3b. Then, as shown in FIG. 2, the nozzle 3a is inserted into the mouth of the container to be refilled, and the contents are replenished while the open end of the bulging portion 3b is expanded as shown by a two-dot chain line in FIG.

  Since the bulging part 3b is formed flat like the body wall part 1, it is important to push it out with a finger or the like when supplying the contents.

  When the bulging portion 3b is expanded, the content replenishment port is expanded, and the content can be easily poured. Therefore, the replenishment operation can be performed relatively easily.

  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. 4 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, about the bottom wall part 2, it is possible to form the concave or convex line connected to the other side wall through the bottom wall part 2 from one side wall, and this makes it easy to fold the container.

  The volume can be reduced by folding the container in the same way as a pouch, and the contents can be replenished using a funnel, making it easy to refill and use in a wide range of applications.

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 replenishment condition of the contents. It is explanatory drawing of the replenishment condition of the contents. It is the figure which showed other embodiment of this invention.
