Abstract

PROBLEM TO BE SOLVED: To provide a simple plastic container which allows its contents to be poured out easily.SOLUTION: The plastic container formed by fusing together plastic films includes a storage area serving as a space in which contents can be stored, and a peripheral area which is formed outside the storage area and does not contain the contents. An elongate pocket space is formed in the peripheral area and a handle is formed by inserting a stick made of a hard material into the pocket space. A user holds the handle and tilts the container such that the contents are poured out of the storage area.

Description

  The present invention relates to a container manufactured using a plastic film.

  Currently, containers using plastic films are widely used in the field of refill detergents and the like. A vase made of plastic fill is disclosed in Patent Document 1. Such a plastic-fill container has advantages such as light weight, easy to carry, hard to break, and easy to dispose.

  However, the conventional plastic film container is lightweight and flexible, but when the liquid in the contents is transferred to another container, the container itself is deformed when the container is grasped, and the contents are poured obliquely. It was difficult to put out.

(Use of the present invention)
Plastic containers according to the present invention include vases, jugs (decanters, pitchers), detergent containers, medical containers (drip solution containers), seasoning containers, beverage containers (water, juice, milk, wine, beer, etc.), agricultural and horticultural supplies It can be applied to containers (fertilizers, chemicals, seeds, soils), pet food containers, food containers (rice, instant coffee powder, cereals, beans, etc.), watering cans, camping water tanks and the like.

(Form of contents)
The contents (contents) accommodated in the plastic container 100 according to the present invention are liquid (water, cosmetics, seasonings, paint, paint), granular (food, pet food), granular (chemicals, fertilizer). ), And gel (cosmetics, adhesive).

  Hereinafter, a “pitch” as an example of the plastic container of the present invention will be described in detail. FIG. 1 is a plan view showing the structure of a plastic container 100 according to the first embodiment of the present invention. FIG. 2 is a plan view showing the stick 108 used in the plastic container 100 shown in FIG. A plastic container 100 according to the present embodiment is a jug formed by fusing a plastic film, and a storage area 102 as a space capable of storing the contents (110); 110) and a peripheral region 104 that is not accommodated.

  In the peripheral region 104, a long and narrow pocket space 106 extending in a direction slightly inclined from the vertical is formed, and a handle is formed in the pocket space 106 by inserting a stick 108 made of a hard material such as an acrylic rod. The The contents (110) are poured out from the upper end 102a of the storage area 102 by holding the handle (106, 108) and tilting the container 100. The pocket space 106 can be easily tilted by gripping the handle (106, 108) by tilting the upper end of the pocket space 106 so as to approach the containing area 102 (in the direction of pouring). Even when extending vertically, it can be used as a handle.

  A container having the same form as the container 100 according to the present embodiment is suitable for a vase, a jug, a watering can, a camping water tank, etc. in addition to a jug (decanter, pitcher).

  As the plastic film forming the container 100 of this embodiment, a material generally used for so-called standing pouches can be employed. For example, high-pressure low-density polyethylene (HP-LDPE), linear low-density polyethylene (LLDPE), linear ultra-low-density polyethylene (VLDPE), metallocene-catalyzed polyethylene (MCAT-PE), high-density polyethylene (HDPE) , Ethylene-vinyl acetate copolymer (EVA), ethylene-ethyl acrylate copolymer (EEA), ethylene-acrylic acid copolymer (EAA), ionomer, ethylene-vinyl alcohol copolymer (EVOH), polypropylene (PP ), Nylon (Ny), polyimide (PIM), polyester (PET), polycarbonate (PC) and the like, or a multilayer film selected from them. Moreover, these single layer films and multilayer films may be stretched, and for example, a biaxially stretched polyamide film (OPA), a biaxially stretched polyester film (OPET), a biaxially stretched polypropylene film (OPP) or the like is used. be able to.

  As shown in FIG. 1, the container 100 according to the present embodiment is generally formed in a rectangular shape, and the storage area 102 is shaped like a vase with a curved bottom so that it can stand on its own. . The upper end portion 102a of the storage area 102 is opened in advance, and the corner portion serving as a spout is rounded (with an R). As a result, the contents 100 are not easily overflowed and can be poured out stably. Needless to say, the shape of the accommodation region 102 is not limited to the shape shown in FIG.

  The peripheral region 104 is formed by fusing two plastic films. The pocket space 106 is a portion into which the stick 108 shown in FIG. 2 is inserted, and is formed with the upper end portion 106a opened in advance. The size of the pocket space 106 is set with a margin so that the stick 108 can be inserted smoothly. It is possible to take measures such as changing the thickness of the plastic film so that the pocket space 106 is formed in the peripheral region 104 and the strength (rigidity) of the portion is increased.

  As the stick 108, it is preferable to employ an acrylic rod that is hard, lightweight, and easy to process. Furthermore, the acrylic rod has the merit that it is easy to add a color or a pattern. As the stick 108, in addition to an acrylic rod, a metal rod such as aluminum or a wooden rod, or a hollow pipe can be used. What is important is that it is stable when the handle part (106, 108) is held with the contents 110 in the storage area 104, and other materials can be used if the same function / effect can be obtained. It is also possible to adopt. In the present embodiment, the lower end (tip in the insertion direction) 108b of the stick 108 has a smooth hemispherical shape so that it can be easily inserted.

  3 and 4 are plan views showing the usage (assembly) state of the plastic container 100 and the stick 108. FIG. First, as shown in FIG. 3, the stick 108 is inserted into the pocket space 106. Then, the state which put the contents 110, such as water, in the inside of the storage area | region 102 is shown in FIG. Although FIG. 4 is a plan view, it is difficult to understand, but in actuality, the bottom portion of the accommodation region 102 is widened to have a shape (standing pouch shape) that can stand on its own.

  When carrying the container 100 containing the contents 110, the part into which the stick 108 is inserted is gripped as shown in FIG. Furthermore, when the content 110 contained in the container 100 is poured out, the container 100 is tilted by gripping the handle portions (106, 108) as shown in FIG. In the present embodiment, since the hard stick 108 is inserted into a part of the soft container body, the rigidity of the portion where the stick 108 is inserted is increased, the container 100 is stably held, and the contents 110 are held. It becomes possible to pour out easily.

  FIG. 6 is a plan view showing a structure of a plastic container 200 according to the second embodiment of the present invention. FIG. 7 is a plan view showing how to use the plastic container 200 shown in FIG. In the present embodiment, the housing region 202 and the upper end portions 202a and 206a of the pocket space 206 are sealed when not in use. And as shown in FIG. 7, it is set as a container by cutting off an upper end part from the tear line 212 before use. A predetermined content 210 can be stored in the storage area 202 in advance.

  A stick (108) (not shown) is inserted into the pocket space 206. Since the basic structure is the same as that of the first embodiment described above, a duplicate description is omitted. The structure as in the present embodiment includes, for example, a detergent container (including refill container), a medical container (drip solution container), a seasoning container (including refill container), and a beverage container (water, juice, milk, wine). , Beer, etc.), agricultural and horticultural containers (fertilizers, chemicals, seeds, soils), pet food containers, food containers (rice, instant coffee powder, cereals, beans, etc.). When the upper end of the container is torn and used as in this embodiment, a known chuck mechanism can be adopted so that it can be reused (resealed).

  FIG. 8 is a plan view showing the structure of a plastic container 300 according to the third embodiment of the present invention.
