Regarding a pouring container using a container body.

In the dispensing container in which the nozzle is attached to the container body for accommodating the contents, it is known that a container body having a double structure having an inner layer for accommodating the contents and an outer layer for accommodating the inner layer is used. (See, for example, Patent Document 1). In this type of container, even if the contents are poured out, air is introduced between the outer layer and the inner layer through the opening provided in the outer layer, and only the inner layer is reduced in volume and deformed, so that the contents are small. There is an advantage that the independence of the container is maintained even if it becomes. Further, by squeezing the outer layer body, the contents can be poured out without replacing with the outside air, so that there is an advantage that the quality of the contained contents is less likely to deteriorate. For this reason, conventionally, the contents are relatively suitable as shown in Patent Document 1, which is suitable for accommodating seasonings such as soy sauce, sauce, mirin, and cooking liquor, and cosmetics such as shampoo, conditioner, liquid soap, and lotion. A large amount of stationary bottle-type containers are often used.

Refers to the orientation when is located above.

The pouring container of the present embodiment includes a container body 1 (composed of an inner layer 2 and an outer layer 3), a nozzle 4A, a cap 5A, and a tail 6A, and is formed in a stick shape as a whole.

The inner layer 2 is provided with a filling space S inside which the contents can be accommodated. The inner layer 2 of the present embodiment is made of a thin-walled synthetic resin and is provided so as to be deformable in volume reduction. As the synthetic resin constituting the inner layer 2, for example, nylon resin (PA), ethylene vinyl alcohol copolymer resin (EVOH), and modified polyolefin resin (for example, "Admer" (registered trademark) manufactured by Mitsui Chemicals Co., Ltd.) are adopted. be able to. The pouring container shown in FIG. 1 is a small-quantity type container having an internal volume of about 3 to 10 cc in the filling space S.

The outer layer 3 forms the outer shell of the container body 1 by accommodating the inner layer 2 inside, and is formed of a synthetic resin having low compatibility with the synthetic resin of the inner layer 2 in the present embodiment. As the synthetic resin constituting the outer layer body 3, for example, polyethylene resin (PE) such as low density polyethylene (LDPE) and high density polyethylene resin (HDPE) can be adopted.

In the inner layer body 2 and the outer layer body 3 of the present embodiment, the above-mentioned resins are melted and co-extruded through a die to form a cylindrical laminated parison, and the laminated parison is blow-molded. It is obtained by doing so. Here, although the inner layer body 2 is in a state of being laminated on the outer layer body 3 after molding, it can be easily peeled off from the outer layer body 3 as the contents decrease because the compatibility with each other is low. The inner layer 2 may be separated from the outer layer 3 in advance by reducing the pressure in the filling space S before accommodating the contents.

The outer layer body 3 has a vertically long tubular shape and has a flexible body portion 3a. As shown in FIG. 2A, a shoulder portion 3b whose diameter is reduced upward is integrally connected to the upper end of the body portion 3a, and the upper end of the shoulder portion 3b has a tubular shape and an upper portion.

Further, at the lower end of the rear end portion 3g, a bottom crack-shaped opening 3i that penetrates the front and back surfaces of the rear end portion 3g is provided. The opening 3i of the present embodiment is formed by utilizing a pinch-off portion formed by cutting off a cylindrical laminated parison when closing a blow molding split die. That is, in the pinch-off portion, as shown in FIG. 2C, the outer layer 3 is located outside the pair of inner layers 2, but the inner layers 2 which are the same type of resin are firmly bonded to each other. Since the inner layer 2 and the outer layer 3 have low compatibility, they can be easily peeled off. As a result, the opening 3i can be formed between the inner layer body 2 and the outer layer body 3.

In forming the inner layer body and the outer layer body, for example, a test tubular preform in which the synthetic resin material of the inner layer body and the synthetic resin material of the outer layer body are laminated is prepared, and this preform is biaxially stretched and blow-molded. It is also possible to use the one in which the outer layer body and the inner layer body are individually formed and then the inner layer body is arranged inside the outer layer body. Further, when providing the opening, a mold having a convex portion corresponding to the opening may be used in a mold for forming the outer layer body so that a through hole is formed at the time of molding, or a pre-formed outer layer body may be used later.

Further, even if the pressing of the body portion 3a is released, the contents of the passage 341e are held by a large resistance, so that the contents do not flow back into the filling space S.

As described above, various nozzles can be adopted for the pouring container according to the present invention, but various tails can also be adopted. For example, the tail 6B shown in FIG. 3B is composed of the tail body 161 without the above-mentioned air check valve. The tail body 161 includes a tubular outer peripheral wall 161a that surrounds the stepped portion 3f and the rear end portion 3g, and a bottom wall 161b that closes the lower end portion of the outer peripheral wall 161a, and is provided on the inner peripheral surface of the outer peripheral wall 161a.

Most of the tip of the outer peripheral wall 161a is in airtight contact with the outer peripheral surface of the step portion 3f, but a part of the tip is recessed outward in the radial direction, and this is used as the outside air introduction port 161d. The outside air introduction port 161d communicates with the opening 3i of the outer layer 3 through a minute gap formed between the second male threaded portion 3h and the second female threaded portion 161c.

In the tail 6B having such a form, when the body portion 3a is pressed, pressure is also applied to the air between the inner layer body 2 and the outer layer body 3, so that this air passes through the opening 3i and the second male screw portion 3h. It tries to flow toward the gap formed between the second female thread portion 161c and the second female thread portion 161c. However, since this gap is minute and a large resistance is applied when it flows, the air leaking from the outside air introduction port 161d to the outside world can be reduced as much as possible. Therefore, even with the tail 6B having such a form, the contents can be poured out in the same manner as in the above-described embodiment. On the other hand, when the pressing of the body portion 3a is released, the body portion 3a tries to return to the original shape, so that the space between the inner layer body 2 and the outer layer body 3 is depressurized. As a result, the air in the outside world flows from the outside air introduction port 161d into the opening 3i through the gap between the second male threaded portion 3h and the second female threaded portion 161c, and the outer layer body 3 is deformed while the inner layer body 2 is reduced in volume. It can be restored. The degree of pouring out the contents and the degree of taking in outside air are optimized by appropriately adjusting the rigidity of the body portion 3a and the size of the gap between the second male screw portion 3h and the second female screw portion 161c. It is possible to plan.

The pouring container according to the present invention is not limited to the embodiments described so far, and various modifications may be made within the scope of the claims, or other configurations may be added. May be good.
