Description

Packaging container

The present invention is packaged as a content of foods and drinks such as seasonings and beverages, cosmetics, chemicals, detergents, etc. that are liquid, pasty, powdery, and those in which small volumes of solids are mixed. It relates to packaging containers.

Currently, various packaging containers have been proposed and distributed in the market. As an example, there has been proposed a packaging container in which a hand is not soiled by the contents when opened by pinching with a finger and performing a bending operation (see Patent Document 1).

The container described in Patent Document 1 is formed by adhering a peripheral edge portion of a flexible container body having a pocket portion to the back surface of a relatively solid and flat sheet-like lid. Further, a folding line that is half-cut or the like is formed at the center of the surface of the lid so that the lid can be easily folded. Furthermore, in order to facilitate the pouring of the contents stored in the pocket portion, a projection having a pyramid shape or a truncated cone shape is provided at the center of the folding line.

Japanese Patent No. 4185359

However, since Patent Document 1 uses a hard material as a material for the lid, a certain amount of force is required to bend it, no matter how half-cut or the like. For this reason, when a weaker elderly person or a child performs a bending operation to pour out the contents, the contents may jump out excessively. Moreover, when solid content is contained in the contents, there is also a problem that clogging is likely to occur during pouring.

The present invention has been made in view of the above problems. That is, an object of the present invention is to provide a packaging container that can pour contents without dirtying hands even for elderly people or children with weak power. It is another object of the present invention to provide a packaging container that is not easily clogged at the time of pouring even when the content contains a solid.

The present invention that solves the above-described problems is characterized in that the container body having an opening on the upper surface of the housing portion and having a flange portion extending outward from the opening portion is bonded to the entire area of the flange portion. A packaging container comprising: a flexible sheet lid member for sealing the housing portion, wherein the container body is partitioned by a ridge portion, and the lid member has an opening for forming a spout Is a packaging container provided so as to cross the twill.

According to such a configuration, by using a flexible sheet as the lid, it is possible for an elderly person or a child with weak power to bend the packaging container without applying any force. Moreover, since the contents can be poured out by folding the packaging container, the contents can be poured out without getting the hands dirty. Furthermore, by providing an opening line so as to intersect with the ridge, the spout can be provided larger as required. Thereby, even if it is the content containing a solid substance etc., a content can be poured out without clogging.

In the package, it is preferable that the ridge portion is provided along a diagonal line of the container main body or the width direction of the main body, and a spout is provided on at least one end side of the ridge portion.

According to such a configuration, since the accommodating portions come into contact with each other when they are bent and pressed against each other, the contents can be more easily poured out.

According to the present invention, the contents can be poured out even if the elderly person or a child with weak power does not get his hands dirty. Moreover, since the size of the spout can be changed according to the size of the solid matter in the contents, it is difficult to clog at the time of pouring.

As shown in FIG. 1A, the packaging container 1 includes a container body 10 made of synthetic resin and a lid member 20 welded to the container body 10. Packing container 1 hermetically contains contents such as seasonings and beverages such as foods and drinks, cosmetics, chemicals, detergents, etc. that are liquid, pasty, powdery, and those that contain a mixture of small volumes of solids. Is to do.

The container body 10 is formed with a pair of recesses (corresponding to the storage portion of the present invention; hereinafter, simply referred to as “storage portion 11”), and the pair of recesses are arranged in parallel with each other. And the side wall 13 which a pair of recessed part faces is extended toward the opposing recessed part, and recessed parts are connected (refer FIG.1 (b)). In other words, the container main body accommodating portion 11 is partitioned by the ridge portion 30 provided so as to extend over the entire width of the container main body. Further, the ridge portion 30 is disposed in proximity to the lid member 20.

In the present embodiment, a protruding portion 40 protruding outward is provided on the side wall on one end side of the ridge portion 30 (see FIGS. 1C and 1D). The protruding portion 40 is provided so as to straddle both the accommodating portions 11 in a substantially line symmetrical manner with the ridge portion 30 as the center. Further, a flange portion 50 is integrally formed with the housing portion 11 at the peripheral portion of the housing portion 11 in the outward direction.

The container body 10 according to the present embodiment is formed by integral molding from a flexible soft synthetic resin sheet such as polyethylene. The soft synthetic resin sheet may be a single layer or may be laminated. The soft synthetic resin sheet preferably has gas barrier properties such as oxygen and water vapor.

In this embodiment, the flexible synthetic resin sheet can be formed into the container body 10 by drawing. As a molding method other than drawing, a known molding method such as pressure forming (vacuum / pressure forming, extrusion / pressure forming, hot plate pressure forming, etc.), vacuum forming, press forming, or the like can be used.

The lid member 20 is a soft synthetic resin sheet having flexibility similar to the container body 10, and seals the housing part 11 by bonding to the flange part 50 of the container body 10. Further, an opening tongue piece 60 that is not bonded to the flange portion 50 is provided in a part of the lid member 20. Further, the lid member 20 is provided with an opening line 70 so as to intersect with the ridge 30, so that a spout 80 for pouring the contents by opening according to the opening line 70 is formed. It has become. The shape of the opening line 70 is not particularly limited, but is preferably a curved line. By making the opening line 70 a curved line, the spout 80 can be enlarged.

The lid member 20 according to the present embodiment may be formed in advance by punching, or may be punched into a predetermined shape together with the container body 10 after being bonded to the flange portion 50 of the container body 10. Moreover, the opening line 70 provided on the lid member 20 may be formed in advance on a soft synthetic resin sheet, or may be formed after being bonded to the container body 10. Examples of the method for forming the opening line 70 include half-cutting and laser processing. *

In the present embodiment, as shown in FIG. 1C, the peripheral edge of the lid member 20 bonded to the flange 50 and the opening tongue piece 60 are shaped like a v-notch (hereinafter simply referred to as “v-notch”). .) Moreover, in this embodiment, the opening line 70 is provided so that the front-end | tips of v notch may be tied. In addition to the v-notch shape, a U-shape or a simple constriction shape may be used.

The packaging container 1 of the present embodiment is configured as described above, and the contents are accommodated in the accommodating portion 11 of the container body 10, and the contents are sealed by bonding the flange portion 50 of the container body 10 and the lid member 20. Is done.

Subsequently, a method for taking out the contents from the packaging container 1 according to the present embodiment will be described with reference to FIG. In order to take out the contents stored in the storage portion 11, the opening tongue piece 60 of the lid member 20 is picked with a fingertip, and the opening tongue piece 60 is pulled up to the upper surface side of the lid member 20 (see FIG. 2A). . Then, force concentrates on the tip of the v-notch, and the lid member 20 is cut open along the opening line 70. The cut line starting from the front end of the opening line 70 follows the opening line 70, passes over the protrusion 40, and reaches the other end of the opening line 70. Thereby, the spout 80 is made.

Next, the container body 10 is folded in two along the ridge 30 with the spout 80 facing upward. When folded in half, the accommodating portions 11 are pressed against each other, and the contents are pushed out from the spout 80 (see FIG. 2B). Here, as shown in FIG. 1D, the bottom surface of the spout 80 is inclined from the flange portion 50 toward the bottom surface of the housing portion 11. Therefore, when the contents are poured out, the contents can be prevented from scattering in an unexpected direction. Finally, all the contents can be squeezed out by bending the container body 10 to such an extent that the entire accommodating portion 11 is crushed. Further, the contents may be squeezed out while squeezing with a finger as necessary (see FIG. 2C).

As described above, the packaging container 1 according to this embodiment has the following effects. The packaging container 1 according to this embodiment squeezes out after forming the spout 80 in advance. Therefore, no pressure is applied to the inside of the container when squeezing out, and there is no risk of the contents scattering. Moreover, since the packaging container 1 which concerns on this embodiment is a soft synthetic resin film which has flexibility, it can squeeze with little force and can squeeze the contents to the last, without getting a hand dirty.

The present invention is not limited to the above embodiment, and may be as follows, for example. FIG. 3 shows another embodiment of the present invention. As another embodiment, the ridgeline 30 is provided on a diagonal line of the container body 10. By setting it as such a shape, the corner | angular part of the container main body 1 can be used as the spout 80. FIG. Therefore, it is not necessary to form a separate protrusion. At this time, it is preferable that the bottom surface of the spout 80 is inclined.

Furthermore, in the present invention, as shown in FIG. 4A, a plurality of opening tongue pieces 60 and a plurality of opening lines 70 may be provided. Further, as shown in FIG. 4B, a plurality of opening tongue pieces 60 and a plurality of opening lines 70 may be provided at different positions on the left and right. By providing a plurality, the spout 80 can be changed to a desired size. Thereby, even when the content extraction amount is appropriately adjusted, or the content is clogged in the spout 80, the spout 80 can be enlarged again without causing the content to scatter.

In the present invention, the top of the ridge 30 and the lid member 20 may be bonded. Thereby, the accommodating part 11 can be made independent and a different content for every accommodating part 11 can be accommodated.
