  Hereinafter, embodiments of the present invention will be described in detail. However, the present invention is not limited to the following embodiments, and may be implemented with appropriate modifications within the scope of the object of the present invention. it can.

<Liquid container>
As shown in FIGS. 1 to 4, the liquid material storage container 1 of the present embodiment is a so-called portion container including a container body 10 and a lid member 30 that covers the opening 11. The container body 10 includes an opening 11 and a flange portion 12 is formed. In addition, a circumferential seal portion 20 is formed on the flange portion 12. The seal part 20 is a sealing means such as heat, ultrasonic wave, high frequency, etc., in which the container body 10 and the lid member 30 are sealed, and the lid member 30 and the flange part 12 are circumferentially sealed and joined. A liquid material (not shown) is sealed. In the present invention, the circumferential seal portion 20 refers to a seal portion formed over one circumference, and is not limited to a circumferential shape, and may be a polygonal shape, or a circumferential shape and a polygonal shape. May be combined.

[Container body]
The container body 10 can be molded by, for example, an injection molding method or a sheet molding method. As a material constituting the container body 10, plastic such as polystyrene, polypropylene, polyethylene terephthalate, or the like can be used. The container body 10 includes a bottom portion 14, a wall portion 13 erected from the bottom portion 14, and a flange portion 12 that is continuously provided on the upper edge of the wall portion 13. As shown in FIG. 3, the wall part 13 has a step part. Moreover, the container main body 10 has a convex portion 140 formed as a pressing assisting portion for assisting pressing with a finger from the bottom side on the bottom portion 14 of the container main body. The convex portion 140 is composed of a plurality of first convex portions 141. The first convex portion 141 extends linearly in a direction intersecting with a line connecting the notch 24 and the center of gravity of the opening 11. By providing the convex portion 140, the user can easily apply pressure to the inside of the liquid material container. Moreover, since the 1st convex part 141 also has the effect which makes a finger hard to slip, it can make it easy to apply a pressure to the inside of a liquid substance storage container further.

  In addition, the shape of the pressing auxiliary | assistant part may be comprised by the convex part like the container main body 10 of FIGS. 1-4, and may be comprised by the recessed part or the level | step difference part. In the case where the pressing assisting portion is a concave portion, it is easy to apply pressure, and therefore it is possible to easily apply pressure to the inside of the liquid material container. In addition, as above-mentioned, a press auxiliary | assistant part may be comprised by a some convex part, may be comprised by a some recessed part, and may be comprised combining a convex part and a recessed part. For example, a convex portion may be formed inside the concave portion, or a concave portion may be formed inside the convex portion. By forming a pressing assist part composed of a convex part, a concave part or a step part for assisting pressing with a finger from the bottom part, the user can easily apply pressure to the inside of the liquid material container. Can do.

  The size and shape of the container main body in the present invention are not particularly limited as long as it has an opening and a flange formed around the opening, and is within a range that does not impair the effects of the present invention. However, since the present invention is configured to peel off the seal portion by pressing with a finger against the container body and the lid material, the body of the container body is deformed by pressing when pressed with the finger. It is necessary to have such flexibility. From the viewpoint of this flexibility and the viewpoint of maintaining the rigidity of the container body, the thickness of the body portion 15 of the container body is preferably 100 μm or more and 500 μm or less, preferably 100 μm or more and 300 μm or less, depending on the material. More preferably.

[Cover material]
As the material of the base material layer that is a laminate including at least the base material layer and the sealant layer, the lid member 30 can be made of plastic such as polyethylene terephthalate, nylon, or polypropylene, or paper. Moreover, as a material constituting the sealant layer, polypropylene, a mixed resin of polypropylene and polyethylene, or the like can be used. A mixed resin of polypropylene and polyethylene is a so-called easy peel sealant.

  A printed layer may be formed on the laminated body constituting the lid member 30, and an extraction position display unit to be described later may be configured by displaying the printed layer. In addition, a barrier layer such as a metal foil such as an aluminum foil, an inorganic material such as aluminum, or an inorganic oxide such as silicon oxide or aluminum oxide may be disposed in the laminate.

[Pouring start point and pour start point seal]
As shown in FIG. 1, a dispensing start portion 21 is formed in a part of the seal portion 20 relating to the present embodiment, specifically, in the vicinity of the notch 24 of the flange portion 12. This pour start point 21 means a part of the seal part 20 that allows the liquid substance to be poured by peeling off the seal part 20 when the pressure in the liquid container rises by pressing with a finger. In form, it is synonymous with the pouring start point seal part 21. The liquid material in the liquid material container can be poured out by the dispensing start point seal portion 21 by pressing with a finger.

  More specifically, the dispensing start point seal portion 21 is a weak seal portion having so-called easy-adhesive easy-opening properties, while the seal portions 23 other than the dispensing start point seal portion 21 are so-called normal strength seals. The container body 10 and the lid member 30 are firmly bonded by heat sealing or the like. That is, the seal strength of the pouring start point seal portion 21 is smaller than the seal strength of the seal portions 23 other than the pouring start point seal portion 21. For this reason, when the pressure in the liquid material container is increased, the discharge start point seal portion 21 of the weak seal in the seal portion 20 can be easily peeled first. Thereby, a clearance gap is formed between the flange part 12 of the container main body 10, and the cover material 30, and the liquid substance in a liquid substance storage container can be poured out. Therefore, the user can pour out the liquid material even with the finger of only one hand.

  Note that the notch 24 is not essential in the present invention, but the notch 24 has a gap between the flange portion 12 of the container body 10 and the lid member 30 when pressure is applied to the container body 10. Since it can make it easy to form, it has the function which makes it easier to pour out the liquid material poured out from the pouring start part 21 outside.

  Each seal strength is preferably 20 N or more, more preferably 20 N or more and 50 N or less (hereinafter also referred to as a strong seal). On the other hand, the sealing strength of the pouring start point seal portion 21 at a width of 15 mm is 5N or more and less than 20N, preferably 8N or more and 12N or less (hereinafter also referred to as weak seal). If it is within this range, it is possible to prevent the seal portion 23 from being peeled off and to make the pouring start point seal portion 21 easy to peel off. Therefore, the liquid material is poured from the pouring start point portion 21 only by pressing with a finger. It can be made easy to take out. In addition, it is preferable that the seal strength difference of the seal part 23 in 15 mm width and the extraction origin seal part 21 is 8N or more and 12N or less.

  Further, the area of the pour starting point seal portion 21 is preferably 15% or less, more preferably 3% or more and 10% or less of the area of the circumferential seal portion 20.

  The seal strength can be measured using, for example, a Tensilon tensile tester (Orientec Co., Ltd., RTC-1310A). Hereinafter, an example of a procedure for measuring the seal strength will be described. First, the liquid material container sample in which the lid member 30 and the flange portion 12 are joined is cut into a width of 15 mm. Next, a part of the lid member 30 is sandwiched with one of the tensilon gripping jigs, and the flange portion 12 is sandwiched with the other gripping jig. Then, it is pulled at a pulling speed of 300 mm / min so that the angle formed by the lid member 30 and the flange portion 12 is 180 °. And let the maximum value of the measured load be seal strength.

  As a method of forming the strength of the seal strength as described above, a so-called easy-release coating agent is applied in a pattern only to a position corresponding to the pouring start point seal portion 21 in the seal portion 20 on the surface of the sealant layer of the lid member 30. Thus, a method in which the pour starting point seal portion 21 is a weak seal and the seal portions 23 other than the pour start point seal portion 21 are strong seals can be exemplified. As the easy-release coating agent, for example, an ink (for example, DIC Corporation, Polycoat P-91, solid content 10%) containing silicone resin and cellulose resin as main components and ethyl acetate as a solvent is used. it can.

  As another method, a method of performing heat sealing in two stages can be exemplified. For example, the first heat seal is heat-sealed at a low temperature so that the entire seal portion 20 becomes a weak seal, and the second heat seal is a high temperature so that the seal portions 23 other than the dispensing start seal portion 21 become a strong seal. By heat-sealing, the pouring start point seal portion 21 can be a weak seal, and the seal portions 23 other than the pouring start point seal portion 21 can be strong seals.

  As another method, by making the seal width of the pouring start point seal portion 21 narrower than the seal width of the seal portion 23 other than the pouring start point seal portion 21, the pouring start point seal portion 21 is made a weak seal, The seal part 23 other than the dispensing start point seal part 21 may be a strong seal. The seal width refers to the width in the direction orthogonal to the direction in which the seal portion extends.

  Further, as shown in FIG. 1, when the pour starting point seal portion 21 has a shape protruding inward, the seal strength of the pour start point seal portion 21 is such that the seal portion 23 other than the pour start point seal portion 21. Even if it is not smaller than the seal strength, the pressure in the liquid material container rises due to the pressure by the finger, and the discharge start point seal portion 21 of the seal portion 20 can be easily peeled first. . For this reason, the liquid substance in a liquid substance container can be poured out by the press by a finger. Therefore, the user can pour out the liquid material even with the finger of only one hand.

[Guide seal part]
In FIG. 1, two guide seal portions 22 connected to one end and the other end of the seal portion 23 other than the pouring start point seal portion 21 and reaching the outer edge of the flange portion 12 are provided with notches 24 in the flange portion 12. It is formed between.

  The guide seal portion is connected to the seal portion 23 other than the discharge start point seal portion 21 and can be discharged by guiding the liquid discharged from the discharge start point portion 21 to the outside of the liquid material container 1. This refers to the seal part. The guide seal portion has a structure (strong seal) that firmly bonds the container body 10 and the lid member 30 similarly to the seal portion 23 other than the dispensing start point portion.

  The guide seal portion 22 is not essential in the liquid material container of the present invention, but it is preferable that a guide seal portion is formed in the liquid material container of the present invention. The container main body 10 and the lid member 30 of the pouring start point 21 are peeled off by pressing with a finger, and the liquid material stored in the container main body is poured out from the pouring start point. Here, since the guide seal portion 22 is formed continuously with the pouring start point portion 21, the liquid material poured out from the pouring start point portion is poured out by the guide seal portion 22 without spreading. . One guide seal portion 22 and the other guide seal portion 22 may include a portion formed so as to approach the outer edge of the flange portion 12.

[Pouring position display section]
In the present invention, it is preferable that the pouring position display portion is formed so that the user can surely recognize the position of the pouring start point portion 21 in the plan view of the liquid material container 1, that is, the pouring direction. . That is, in the present invention, unlike a conventional portion container or the like, the user forms a gap between the flange portion 12 and the lid member 30 by pressing with the finger without peeling off the lid member with the finger, Can be poured out. For this reason, if the position of the pouring start point 21 is wrong, the contents will pop out from the wrong direction. By forming the extraction position display portion, it is possible to prevent misidentification of the extraction position.

  The extraction position display part is not particularly limited as long as it is a means capable of specifying the position of the extraction start part 21 in the plan view of the liquid material container 1. For example, it may be displayed by printing or the like. In a specific example, an arrow indicating an opening location and a direction may be displayed near the pouring start point 21 in the lid member 30, or character information such as “pour from here” may be displayed. “It can be done” may be displayed, or the dispensing start point 21 may be identified by a color or a graphic.

  Moreover, as shown in FIG. 1, the notch 24 formed in the flange 12 is also preferable because it has a function of visually guiding the dispensing position display section.
