Description

  The present invention relates to a hermetic package body filled with a mixture of a liquid and a solid material and a lid material used therefor. More specifically, for example, a liquid that is used for packaging a packaged object in which a solid is immersed in a liquid, such as honey bean agar, pickles, boiled vegetables, boiled beans, etc. The present invention relates to a hermetically sealed package that can easily separate and remove solids and a lid used for the sealed package.

  Conventionally, as a sealed package that allows easy separation and removal of enclosed liquid and solid matter, a half cut for opening to form a hole for discharging liquid (liquid cutting hole), and when discharging liquid The inner layer provided with a half-cut for opening to form a hole for taking in air (air hole) is used as a lid material in which an outer layer is laminated in a peelable manner. A hermetic package in which a container containing a mixture is sealed is known (see Patent Document 1).

  Further describing the sealed package, the container is sealed by fusing the inner side of the peripheral part of the lid to the peripheral part of the opening of the container, and the outer layer is applied outward from the peripheral part of the lid. An outer layer peeling tab for peeling from the inner layer and an inner layer peeling tab for peeling the inner layer from the container protrude. Opening half-cuts that form liquid drain holes and air holes are each formed in an annular shape through the inner layer, and the inner layer part surrounded by the half-cuts for opening is peeled off as the outer layer is peeled off. Then, the liquid draining hole and the air hole are respectively opened in the inner layer. In addition, the opening half cut that forms the air holes is formed at a position close to the outer layer peeling tab, and the opening half cut that forms the liquid cutting holes is the opening half cut that forms the air holes. It is formed on the opposite side.

  To open the sealed package, first, the outer layer peeling tab is pulled, the outer layer is peeled to open the liquid draining hole and the air hole, the container is inclined to the liquid draining hole side, and the liquid is discharged from the liquid draining hole. Thereafter, the inner layer peeling tab is pulled to open the entire opening of the container so that the solid matter can be taken out.

JP 2007-320581 A

  By the way, since the container is filled with the liquid together with the solid matter, the liquid is easily ejected from the opened liquid cut hole or air hole when the outer layer is peeled off. In particular, in the case of the above-described conventional sealed container, since the opening half cut for forming the air hole is formed at a position close to the outer layer peeling tab, the air hole is opened with the outer layer slightly raised. . That is, since the fingertip holding the outer layer peeling tab is near the opened air hole, there is a problem that the liquid ejected from the air hole is likely to adhere to the fingertip, causing slipping or giving unpleasant feeling. Further, since the air hole is a relatively small opening, the liquid is likely to jump out vigorously, and there is a high possibility that not only the fingertip but also the clothes and the surrounding area will be stained.

  The present invention has been made in view of the above-described conventional problems, and when the outer layer is peeled off by pulling the outer layer peeling tab, the outer layer is peeled off even if the liquid pops out from the hole that is opened along with the peeling of the outer layer. It is intended to make it difficult for the liquid to adhere to the fingertip that is picking up the tab. Another object of the present invention is to suppress the momentum of the liquid leaking from the hole and to prevent the liquid from adhering to the inner layer peeling tab.

The present invention seals the container by fusing the inner layer side of the peripheral part of the cover member, which is peeled and laminated to the peripheral part of the opening part of the container filled with a mixture of liquid and solid matter. The outer layer peeling tab for peeling the outer layer from the inner layer and the inner layer peeling tab for peeling the inner layer from the container protrude from the peripheral edge of the lid material to the outer side. The inner layer surrounded by the opening half-cut is peeled off as the outer layer is peeled off, and the holes for liquid discharge and air intake are opened in the inner layer. In a sealed package,
When the area of the lid corresponding to the opening of the container is equally divided into the outer layer peeling tab side and the opposite side, all holes are opened in the area opposite to the outer layer peeling tab side. The present invention provides a sealed package characterized in that a half cut is formed.

The above-mentioned sealed package of the present invention is a half cut in which a half cut for opening has a long and narrow ring shape, and opens a liquid draining and air hole that serves both for liquid discharge and for air intake.
The outer layer peeling tab and the inner layer peeling tab are provided at positions facing each other, and the elongated annular half-cut for opening the liquid drainage and air holes is arranged in the length direction from the direction of the inner layer peeling tab. That it is formed by shifting,
A separation half-cut is formed that separates the outer layer into a non-peeling region that includes an inner layer peeling tab and that covers the half-cut for opening, and a peeling region other than the non-peeling region. thing,
Is included as a preferred embodiment thereof.

In the present invention, the outer layer and the inner layer whose peripheral portion is fused to the peripheral portion of the opening of the container are detachably laminated, and the outer layer is for peeling the outer layer from the inner layer outward from the peripheral portion. The peeling tab and the inner layer peeling tab for peeling the inner layer from the container protrude, and have a half cut for opening formed in an annular shape penetrating the inner layer and opened along with the peeling of the outer layer. In the lid material that peels off the inner layer part surrounded by the half cut for holes and opens holes for liquid discharge and air intake in the inner layer,
When the area corresponding to the opening of the container to be fused is divided into two parts, the outer layer peeling tab side and the opposite side, all the holes are opened in the area opposite to the outer layer peeling tab side. The present invention also provides a lid material characterized in that a half-cut for use is formed.

The lid material of the present invention is a half cut in which the half cut for opening forms an elongated annular shape and opens a liquid draining and air hole that serves both for liquid discharge and for air intake,
The outer layer peeling tab and the inner layer peeling tab are provided at positions facing each other, and the elongated annular half-cut for opening the liquid drainage and air holes is arranged in the length direction from the direction of the inner layer peeling tab. That they are staggered,
A separation half-cut that separates the outer layer into a non-peeling region that includes a tab for inner layer peeling and that covers the half-cut for opening and a separation region other than the non-peeling region is formed. ,
Is included as a preferred embodiment thereof.

  In the present invention, all the half-cuts for opening are formed at positions away from the outer layer peeling tab. For this reason, since the hole is opened only when the outer layer is greatly swung up, the fingertip is separated from the hole by picking the outer layer peeling tab when the hole is opened. For this reason, even if the liquid jumps out of the hole, it is difficult to adhere to the fingertip that is picking the outer layer peeling tab, and slippage and discomfort due to the adhesion of the liquid can be prevented.

  In the present invention, if the half-cut for opening is formed into an elongated ring shape and the liquid-cutting / air hole serving both for discharging liquid and taking in air is opened, a small air hole can be dispensed with. The liquid draining and air holes inevitably have a large opening area, so that even when the liquid jumps out of the hole, it can be prevented from splashing far away, and the situation where the clothes and surroundings are soiled can be prevented. .

  Further, when the elongated annular opening half cut is formed by shifting the length direction from the direction of the inner layer peeling tab, the liquid from the liquid draining and air hole formed by the opening half cut is formed. The discharge direction can be guided in a direction shifted from the inner layer peeling tab, and the liquid can be prevented from adhering to the inner layer peeling tab due to the liquid discharge.

  Further, a separation half cut is formed in the outer layer, the inner layer separation tab is included, and the outer layer is separated into a non-peeling region that is outside the region covering the half-cut for opening and a separation region other than the non-peeling region. In this case, even after the outer layer is peeled from the outer layer peeling tab side and the holes are opened, the outer layer of the non-peeling region is left on the inner layer peeling tab side. In other words, a step corresponding to the thickness of the outer layer is formed between the exposed region of the inner layer where the outer layer is peeled and the hole is opened, and the region where the outer layer is left, and the liquid flows out from the hole onto the exposed inner layer. However, this step can prevent the liquid from flowing to the inner layer peeling tab side.

  Hereinafter, the present invention will be further described with reference to the drawings. In addition, in FIGS. 1-12 demonstrated below, the same code | symbol shows the same member or site | part.

  FIG. 1 is a perspective view of a hermetic package according to the first example of the present invention, FIG. 2 is a schematic cross-sectional view of the hermetic package according to the first example of the present invention, and FIG. Typical sectional drawing which shows an example, FIGS. 4-8 is explanatory drawing of an opening procedure.

  In FIG.1 and FIG.2, 1 is a cover material and 2 is a container.

  The lid 1 is formed by stacking the outer layer 3 and the inner layer 4 so that the outer layer 3 and the inner layer 4 can be peeled off, and the peripheral portion on the inner layer 4 side is fused to the peripheral portion of the opening 5 of the container 2, so The container 2 filled with (not) is sealed.

  An outer layer peeling tab 6 and an inner layer peeling tab 7 protrude outwardly from positions facing each other at the peripheral edge of the lid member 1. At the base of the outer layer peeling tab 6, the inner layer 4 is crossed across the base so that the outer layer 3 can be pulled and peeled from the inner layer 4 when the outer layer peeling tab 6 is picked and pulled upward. A penetrating outer layer peeling half cut 8 is formed.

  Further, the inner layer 4 is formed with an opening half-cut 9 a that is formed in an annular shape so as to penetrate the inner layer 4. The portion of the inner layer 4 surrounded by the opening half-cut 9a is peeled off along with the outer layer 3 as the outer layer 3 is peeled off, and opens holes for discharging liquid and taking in air. . The hole forming half-cut 9a in this example is a half-cut that opens a liquid-cutting / air hole 10 (see FIGS. 5 and 6) that serves both for liquid discharge and for air intake.

  The hole opening half-cut 9a of this example simultaneously discharges liquid and takes in air from the formed liquid draining and air hole 10 (see FIGS. 5 and 6) and outflow of stored solid matter. In order to make it easier to prevent, an elongated annular shape is formed. In order to facilitate the outflow of liquid and the intake of air from the same liquid draining / air hole 10 at the same time, the length of the opening half-cut 9a (liquid draining / air hole 10) is preferably 10 mm or more. The upper limit of the length is less than the transverse length of the opening 5 of the container 2. Further, the width of the opening half-cut 9a (liquid draining / air hole 10) is preferably about 1/2 to 1/5 of the above length, although it depends on the size of the solid matter to be accommodated.

  The opening half-cut 9a in this example is formed in three places, but the lid 1 region corresponding to the opening 5 of the container 2 is divided into two equal parts, the outer layer peeling tab 6 side and the opposite side. In addition, all the half-holes 9a for opening are formed in a region (outer layer separation terminal side region) opposite to the outer layer separation tab 6 side. By forming all the half-holes 9a for opening at such positions, as described in the column of effects, holes that are opened when the outer layer 3 is peeled off (in this example, shown in FIGS. 5 and 6). The liquid leaking from the liquid draining and air holes 10) can be made difficult to adhere to the fingertip. In addition, the dashed-dotted line shown with the code | symbol 11 in FIG. 1 is a bisector which bisects the area | region corresponding to the opening part 5 on the outer layer peeling tab 6 side and its opposite side.

  As shown in FIG. 1, press marks 12, 12 are provided on the peripheral edge of the lid 1 of the sealed package of this example. The pressing marks 12 and 12 are printed marks indicating positions suitable for pressing and stabilizing the package when the outer layer peeling tab 6 is pulled to peel off the outer layer 3, and are provided to facilitate the peeling operation. It is preferable to keep it. Moreover, it is preferable to provide the outer layer peeling tab 6 and the inner layer peeling tab 7 at positions facing each other so that they do not get in the way when pressing the package. Moreover, since the said presser marks 12 and 12 are the positions which are easy to hold down a package stably, in the center part between the outer layer peeling tab 6 and the inner layer peeling tab 7 along the periphery of the cover material 1. FIG. It is preferable to provide it.

  As a specific layer structure of the lid member 1, the layer structure shown in FIG. 3 can be exemplified. The illustrated outer layer 3 of the lid member 1 is laminated in the order of polyamide layer 3a / polyester layer 3b from the outer surface side. The inner layer 4 is formed by laminating in order of the easily peelable resin layer 4a / polyethylene layer 4b / printing layer 4c / polyamide layer 4d / linear type low density polyethylene layer 4e (sealant layer) from the outer layer 3 side. Yes. The outer layer 3 and the inner layer 4 are laminated so as to be peelable at the interface between the polyester layer 3b and the easily peelable resin layer 4a.

  Next, the opening procedure will be described with reference to FIGS.

  First, the outer layer peeling tab 6 is pulled obliquely upward on the container 2 side as shown in FIG. 4 in a state where the pressing marks 12 and 12 (see FIG. 1) are pressed to stabilize the whole. Since the inner layer 4 of the outer layer peeling tab 6 portion is separated from the inner layer 4 on the container 2 side by the outer layer peeling half cut 8, the outer layer 3 is pulled up, and peeling of the outer layer 3 from the inner layer 4 is started. .

  When the outer layer peeling tab 6 is further pulled and the outer layer 3 is peeled off, as shown in FIG. 5, the inner layer 4 portion surrounded by the opening half-cut 9a peels along with the outer layer 3, and the liquid is removed. The air hole 10 is opened. At this time, the outer layer 3 is largely peeled off, and the fingertip having the outer layer peeling tab 6 is separated from the liquid draining / air hole 10, so even if liquid flows out from the liquid draining / air hole 10, Adhesion can be prevented.

  The state where the peeling of the outer layer 3 is completed is the state shown in FIG. In this state, as shown in FIG. 7, when the container 2 is inclined in the length direction of the liquid draining / air hole 10, the liquid draining is performed while taking air into the container 2 from a part of the liquid draining / air hole 10. The liquid in the container 2 can be discharged from the cum air hole 10 and only the solid matter can be left in the container 2.

  When the inner layer peeling tab 7 is pulled after the liquid is discharged and the inner layer is peeled off from the container 2, the opening 5 of the container 2 can be completely opened as shown in FIG. Solids can be easily removed.

  FIG. 9 is a perspective view of a hermetic package according to a second example of the present invention.

  The sealed package of the present example is basically the same as the first example, but includes an opening half cut 9b that forms a liquid draining hole that is a hole for discharging liquid, and an air intake hole. An opening half cut 9c that forms a certain air hole is provided. Both the opening half-cut 9b and the opening half-cut 9c are circular, but the opening half-cut 9c that forms the air holes is smaller than the opening half-cut 9b that forms the liquid-cutting holes. It has a small diameter.

  Even if the opening half-cut 9c for forming air holes is provided as in this example, if all the opening half-cuts 9b and 9c are formed in the outer layer peeling termination side region, the leaked liquid Adhesion to the finger can be prevented. However, there is a risk that the liquid may vigorously jump out of the air hole that is generally formed as a hole having a smaller diameter than the liquid cutting hole. For this reason, as described in the first example, the opening half-cut 9a (see FIG. 5) for opening the liquid draining and air hole 10 (see FIGS. 5 and 6) serving both for discharging liquid and for taking in air. 1), and it is preferable not to provide the opening half-cut 9c for forming the air holes.

  FIG. 10 is a perspective view of a hermetic package according to a third example of the present invention.

  The opening half-cut 9a in this example is a half-cut for opening the elongated liquid draining and air hole 10 (see FIG. 5 and FIG. 6) as in the first example. 7 shifted from the direction of 7. Since the liquid is discharged from the liquid draining / air hole 10 by tilting the container 2 in the length direction of the liquid draining / air hole 10, the liquid discharging direction is shifted from the inner layer peeling tab 7. Can be guided to. Therefore, it is possible to prevent the liquid from adhering to the inner layer peeling tab 7 due to the discharge of the liquid.

  FIG. 11 is a perspective view of a sealed package body according to a fourth example of the present invention, and FIG. 12 is a perspective view of a state where an outer layer of a peeling region of the sealed package body according to the fourth example of the present invention is peeled off.

  The sealed package of this example is basically the same as the third example, but the outer layer 3 includes the inner layer peeling tab 7 and is out of the region covering the hole half cut 9a. The difference is that a separation half-cut 15 penetrating the outer layer 3 is formed which separates into a non-peeling region 13 and a peeling region 14 other than the non-peeling region. In this example, when the outer layer 3 is peeled from the outer layer peeling tab 6 side, since the separation half-cut 15 is formed, only the outer layer 3 in the peeling region 14 is peeled and the outer layer 3 in the non-peeling region 13 remains. Then, the state shown in FIG. 12 is obtained. As shown in FIG. 12, the outer layer 3 is between the inner layer 4 exposed by peeling the outer layer 3 of the peeling region 14 and the region on the inner layer peeling tab 7 side where the outer layer 3 of the non-peeling region 13 is left. The difference in thickness is generated. For this reason, even if the liquid overflows from the opened liquid draining / air hole 10 onto the exposed inner layer 4, it is possible to prevent the liquid from flowing to the inner layer peeling tab 7 side by this step.
