Description

  The present invention relates to a container that can be applied to a refill container such as a thin-walled container made of synthetic resin formed by blow molding (direct blow or the like) or a pouch container having a laminated structure of a film, and the contents in the container are poured smoothly. I'm trying to put it out.

  In recent years, as a container for filling contents such as shampoo, rinse, liquid soap, cosmetics, etc., a stationary type container that can be dispensed with an appropriate amount by installing a dispenser in its mouth is used. In order to replenish contents in such a container, a pouch container or a thin-walled blow bottle that requires less material and is not bulky at the time of disposal is used (see, for example, Patent Document 1).

JP-A-11-130112

  By the way, the conventional refill container has relatively many pouring parts, filling ports or design-like irregularities on the outer surface thereof, and the inner space of the container also has corresponding irregularities, In a container in which a high-viscosity product is filled, the unevenness in the container becomes resistance, which hinders the flow of the content and may not be efficiently dispensed.

  The subject of this invention is providing the novel synthetic resin thin-walled container which can pour the contents smoothly irrespective of the level of the viscosity of the contents.

The present invention is a synthetic resin thin-walled container comprising a container main body that enables volume reduction of the body part, and a pouring part that is integrally formed on the upper part of the container main body to form a discharge path for contents,
A synthetic resin characterized in that a funnel-shaped path is provided in the pouring part, which is integrally connected to the container body via a curved surface part and smoothly guides the contents in the container toward the tip of the pouring part. A thin-walled container.

  In the thin-walled container having the above-described configuration, an easily openable plug body that is made of a different material from the pouring portion and can be opened by tearing the connection line at the boundary can be provided at the tip of the pouring portion.

  Moreover, it is desirable that the container main body is provided with a bottom portion that is provided with a filling port for filling the contents in the container and allows the container to stand by itself in a storage state by reversal thereof.

  Since the content is poured out through a funnel-shaped path connected through the curved surface portion, the flow of the content is smooth, and even a highly viscous content can be efficiently refilled. Here, the above contents include liquids other than shampoo, rinse, liquid soap, cosmetics and the like.

  By providing the filling port provided in the container at the bottom of the container, it is possible to reduce resistance that hinders the flow of contents.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
1 and 2 are diagrams showing an embodiment of a thin plastic container made of a synthetic resin according to the present invention shown in an example formed by direct blow molding, FIG. 1 is an external perspective view, and FIG. 2 is a side view. It is.

  Reference numeral 1 in FIGS. 1 and 2 denotes a container body that forms a filling space for contents. As shown in FIG. 3, the container body 1 can fold the body portion including the pouring portion. Further, 2 is a pouring part that is integrally formed on the upper part of the container body 1 to form a discharge path for contents, 3 is a curved surface part, 4 is connected to the container body 1 via the curved surface part 3, and the contents in the container are integrated. A funnel-shaped path for smoothly guiding an object toward the tip of the pouring part 2, 5 is a plug provided at the tip of the pouring part 2, and the plug 5 is connected to the pouring part 2. Are made of different materials, and the container is opened by tearing off the connection line 5a. In the illustrated embodiment, the upper portion of the funnel-shaped path 4 is configured with a straight line extending obliquely upward toward the plug body 5, but it may be configured with a curved line protruding upward. is there.

  Reference numeral 6 denotes a filling port provided at the bottom of the container body 1. The filling port 6 is in a state as shown in FIG. 4 before filling the contents, but after filling the contents and sealing with a heat seal or the like, it is inverted toward the inside of the container and grounded at the bottom. To make the container self-supporting.

  In the container according to the invention, the container body 1 can be formed of medium density polyethylene, and in the case of the above embodiment, the plug body 5 can be made of a resin mainly composed of polypropylene which is a different material from the container body 1. By blending this polypropylene with medium density polyethylene of at least about 30%, a binding strength that does not hinder the tearing of the plug 5 can be obtained. In addition, when opening using tools, such as a bag, unlike the said Example, it is also possible to shape | mold the plug body 5 and the container main body 1 with the same resin.

  In addition to the above, as the resin constituting the container body 1, olefin resins such as low density polyethylene, high density polyethylene, and polypropylene, and polyester resins such as polyethylene terephthalate can be used. In addition to these resins, a barrier layer is formed. It is also possible to adopt a container body configuration having a layer configuration of two or more layers in which EVOH, nylon or the like is laminated as the resin to be used.

  Further, as the resin constituting the plug body 5, when the container body 1 is made of a different material as described above, the plug body 5 is prevented from being broken due to the relationship with the resin constituting the container body 1. Various known resins can be used as long as the resin has a bonding strength of a level that does not occur.

  As described above, in the configuration of the above embodiment, the container 5 is torn off the stopper body 5 that can be separated from the container body 1 with a relatively light force while maintaining an appropriate coupling force with the container body 1. When the container is opened and the container is tilted, the contents in the container flow smoothly from the tip of the pouring part 2 through the curved surface part 3 and the path 4 and can be discharged efficiently.

  In the embodiment of the present invention, a container formed by blow molding is illustrated, but it can of course be applied to a pouch container in which a synthetic resin film and a metal film are laminated, and is limited to a container formed by blow molding. Never happen.

  Moreover, although the filling port of the content can be provided in the bottom part of a container, you may provide in a trunk | drum part, if there is no possibility of inhibiting the flow of a content.

  The configuration of the plug body 5 that is easy to open with the whole material different from the pouring part 2 is illustrated, but the pouring part 2 and the plug body 5 are made of the same material and only the connection line 5a is made of a different material. A configuration as shown in FIG. 5 can also be applied, and this also allows easy opening of the container by tearing.

  In the present invention, it is possible to provide a thin-walled container that enables smooth refilling regardless of the viscosity of the contents filled in the container body.

It is an external appearance perspective view of the thin container according to this invention. It is the figure which showed the side surface of the container shown in FIG. It is the figure which showed the state which folded the container shown in FIG. It is the figure which showed the external appearance before filling of the content about the container shown in FIG. It is a principal part enlarged view of the thin container according to this invention.
