Description

  The present invention relates to a container with a sealing material including a container main body having an opening for discharging contents and a sealing material fixed to the mouth end face of the container main body to seal the opening.

  Conventionally, in the fields of food, cosmetics, pharmaceuticals, etc., in order to prevent the quality deterioration of the contents contained in the container body, it is provided on the mouth end face by fixing a sealing material to the mouth end face of the container body. The inside of the container body is kept airtight by sealing the opened opening (see, for example, Patent Documents 1 and 2).

JP 2010-179948 A JP 2007-145363 A

  By the way, in order to keep the container main body airtight, it is necessary to fix the sealing material to the mouth end face to some extent firmly. In addition, since the outer edge of the mouth end face has a circular shape, even if the sealing material that sealed the opening is peeled off and pulled up, the force at that time is distributed to the circular outer edge. Will join. For this reason, a particularly strong force was required when peeling started. In addition, when the container body has flexibility, force may be applied to the hand holding the container body at the time of peeling, and the contents may be blown out simultaneously with opening.

  With respect to such a problem, Patent Document 2 uses a sealing material as shown in FIGS. In this sealing material, the first tab and the second tab are joined to the center of the base portion fixed to the end surface of the mouth portion, and the first tab and the second tab are raised from the base portion and overlapped with a finger. As a result of lifting the base part by pulling it up as it is, it can be easily peeled off from the end face of the mouth part. However, the sealing material of Patent Document 2 has a complicated structure, and it takes time and effort to manufacture it. In addition, since the structure is complicated, it is difficult to reduce the cost.

  An object of the present invention is to provide a container with a sealing material that requires less force when peeling off the sealing material and has a simple structure. To do.

The present invention provides a mouth portion having a mouth end face having a circular outer edge, a container body having an opening provided on the mouth end face for discharging contents, and being fixed to the mouth end face to seal the opening. A container with a sealing material comprising a sealing material to perform,
The said mouth part is a container with a sealing material which has an end surface which aligns with the said mouth part end surface, and is equipped with at least 1 protrusion which protrudes toward a radial direction outer side.

  It is preferable that the sealing material has a knob that protrudes radially outward with respect to the protrusion.

  It is preferable that the sealing material has a rectangular shape, and the corner portion of the sealing material is fixed at a position protruding radially outward with respect to the protrusion, thereby constituting the knob.

  It is preferable that the container main body has a flat barrel portion connected to the mouth portion.

  A cap that covers the sealing material and is attached to the mouth, and the cap peels off the sealing material and, when attached to the mouth, a discharge port that leads to the opening, and a lid that closes the discharge port It is preferable to provide a body.

  Since the container with the sealing material of the present invention has at least one projection having an end surface aligned with the end surface of the mouth and projecting radially outward, when the sealing material is pulled up toward the projection, The force is concentrated on the outer end of the protrusion. For this reason, even if the force at the time of pulling up is comparatively small, it can begin to peel off the sealing material. Further, since the projection is only provided at the mouth, the structure is simple.

  In the case where the knob is provided on the sealing material so as to protrude radially outward with respect to the protrusion, the knob is easily grasped by a finger, and therefore the sealing material is easily peeled off. In addition, since the knob is located on the outer side in the radial direction of the protrusion, if the knob is grasped and pulled up, a force is applied to the protrusion. Therefore, there is no need to worry about the position of the protrusion when the seal material is peeled off.

  When using a sealing material that has a rectangular shape and fixing it at a position where the corner of this sealing material protrudes radially outward with respect to the projection, the effect of removing the initial force can be reduced. In addition, there is an advantage that the shape of the sealing material is simplified.

  When adopting a container body that has a flat barrel connected to the mouth, positioning the barrel in the circumferential direction also determines the circumferential position of the projection. It becomes easier to align with the sealing material.

  When providing a cap that covers the sealing material and is attached to the mouth, and when this cap is provided with a discharge port that leads to the opening and a lid that closes the discharge port when the sealing material is peeled off and attached to the mouth When the sealant is not used, the sealant can be protected by the cap. In addition, after the sealing material is peeled off in use, the contents can be discharged from the discharge port while the cap is attached to the container body, and the intrusion of outside air from the discharge port can be suppressed by the lid after the discharge is completed.

  Hereinafter, with reference to FIG. 1, one Embodiment of the container with a sealing material according to this invention is described. In this specification and the like, the “upward” direction and the “downward” direction refer to the direction in which the mouth (reference numeral 4) is located above the bottom (reference numeral 2) as shown in FIG. Say.

  As shown in FIG. 1, the container body 1 has a bottom portion 2 with a central portion protruding upward, and a body portion that extends while slightly expanding upward from the outer edge portion of the bottom portion 2 and then contracts the diameter. 3 and a cylindrical mouth portion 4 extending upward from the body portion 3. Here, the body part 3 is formed in a flat shape in a plan view. The mouth portion 4 is provided with a neck ring 5 that circulates around the axis O of the container body 1 and a male screw portion 6 positioned above the neck ring 5.

  Further, a circular mouth annular portion 7 having an outer diameter smaller than that of the portion where the male screw portion 6 is provided is provided above the male screw portion 6. Moreover, the upper end surface of the mouth annular portion 7 which is the end surface (mouth end surface) 8 of the mouth portion 4 is formed flat. The circular annular portion 7 is provided with a circular opening 9 that communicates with the inside of the container body 1. The shape of the opening 9 is arbitrary, and may be, for example, a rectangular shape or a star shape.

  Further, a projection 10 is provided on the outer peripheral surface of the mouth annular portion 7 so as to protrude outward in the radial direction and to extend along the axis O. The protrusion 10 of the present embodiment protrudes so as to taper outward in the radial direction, and has a triangular shape in plan view. Further, in the present embodiment, a total of four protrusions 10 are provided at equal intervals in the circumferential direction (two on the short diameter side of the body 3 that is flat and two on the long diameter side). Here, the end face 11 above the protrusion 10 is provided so as to be aligned with the mouth end face 8 (so that the end face 11 is flush with the mouth end face 8). Further, the outer peripheral surface of the protrusion 10 is formed so as to be positioned radially inward from the outer peripheral surface of the mouth portion 4 at the portion where the male screw portion 6 is provided. As will be described later, the cap is attached to the mouth portion 4, but the outer peripheral surface of the protrusion 10 is in contrast to the outer peripheral surface of the mouth portion 4 in the region where the male screw portion 6 is provided within a range not hindering the cap attachment. And may protrude outward in the radial direction.

  The container main body 1 of the present embodiment is formed of a thin synthetic resin (for example, polyethylene), and the contents accommodated in the container main body 1 can be discharged from the opening 9 by pressing the trunk portion 3. The container body 1 may be formed of a single synthetic resin or may be formed by laminating a plurality of types. The material of the container body 1 is not limited to synthetic resin, and may be glass or the like. Furthermore, the shape of the container main body 1 is not limited to the above-described one, and for example, the body 3 may be cylindrical.

  FIG. 2 is a view showing a state in which the sealing material 12 is fixed to the container body 1 shown in FIG. The sealing material 12 of the present embodiment is formed in a rectangular shape (square shape), and is provided at the mouth end face 8 and the end face 11 so that the corner 13 of the sealing material 12 is located at the position where the protrusion 10 is provided. It is fixed. Here, the corner 13 protrudes radially outward with respect to the protrusion 10 as shown, and can be grasped with a finger when the sealing material 12 is peeled off. The shape of the sealing material 12 is not limited to that shown in the figure. For example, the basic shape may be a circular shape, and a shape that further protrudes radially outward from the circular portion corresponding to the protrusion 10 may be provided. Good. By the way, since the trunk | drum 3 of the container main body 1 of this embodiment is flat shape, if the container main body 1 is hold | maintained with the apparatus which follows the external shape of the trunk | drum 3 in the process of adhering the sealing material 12, the container main body 1 will be an axis line. It will be positioned around O. That is, since the circumferential position of the protrusion 10 is determined, the alignment of the protrusion 10 and the corner 13 when the sealing material 12 is fixed is facilitated.

  In addition, the raw material of the sealing material 12 is not specifically limited, A metal thing like an aluminum film may be sufficient, and a synthetic resin like a polyethylene terephthalate film may be sufficient. Moreover, what laminated | stacked the film made from a metal and the film made from a synthetic resin may be used. Various methods can be applied to fix the sealing material 12, and welding by high-frequency heating or the like, or bonding using an adhesive or the like may be used.

  As shown in FIG. 3, a cap 14 can be attached to the container body 1 in which the sealing material 12 is fixed to the mouth end face 8 in this way. Here, the cap 14 is a cap body having a covered cylinder shape, having a discharge cylinder 16 surrounding a hole (discharge port) 15 provided in the center portion, and having an internal thread portion 17 corresponding to the external thread portion 6 on the inner peripheral surface. 18 is provided. The cap body 18 is provided with a covered cylindrical lid 20 that is integrally connected via a hinge 19 and surrounds the discharge cylinder 16 and is detachably held by the cap body 18. On the lower surface of the lid 20, there is provided a seal portion 21 that comes into contact with the inner peripheral surface of the discharge cylinder 16 when the lid 20 is closed with respect to the cap body 18.

  According to such a container with a sealing material, when the cap 14 is attached to the container main body 1 with the sealing material 12 fixed, the sealing material 12 can be prevented from being damaged, so that the sealing when not in use is used. The state can be reliably maintained.

  Further, when discharging the contents, the cap 14 is removed from the container main body 1, and one of the corners 13 is picked and pulled up as shown in FIG. Here, since the corner portion 13 is located on the outer side in the radial direction than the protrusion 10, it can be easily picked. Further, since the sealing material 12 is fixed so that the corners 13 are located at the positions where the protrusions 10 are provided, the pulling force is concentrated on the outer end portion of the protrusions 10 regardless of which corner part 13 is pulled up. Will do. For this reason, even if the force at the time of pulling up is comparatively small, it can begin to peel off the sealing material 12.

  After the sealing material 12 is peeled off, the cap 14 is attached to the container body 1 again. When the lid 20 is opened and the body 3 is pressed, the contents stored in the container body 1 can be discharged from the discharge cylinder 16 through the opening 9. Further, if the lid 20 is closed, the seal portion 21 comes into contact with the inner peripheral surface of the discharge cylinder 16, so that contact between the contents and the outside air can be suppressed.

  While the present invention has been described with reference to specific embodiments, the container with a sealing material according to the present invention is not limited to the above-described embodiments, and various modifications are made within the scope of the claims. Is also included. For example, at least one protrusion 10 may be provided. In this case, it is preferable to provide a portion (pick portion) to be picked with a finger in the sealing material 12 so as to correspond to the protrusion 10. Further, when a large number of protrusions 10 are provided as shown in FIG. 5A (12 in the illustrated example), the force at the time of peeling is applied to any one of the adjacent protrusions 10. A circular sealing material 12 'as shown in FIG. 5B may be used without providing a large number of knobs corresponding to the above. Further, the cap is not limited to the above-described one. For example, the cap main body and the lid body may be separated, and the cap body may be held by a screw or an undercut with respect to the cap main body. Moreover, you may attach a cover body directly to the opening | mouth part of a container main body, without using a cap main body.
