(A) is a figure which shows the structure of a plug part, FIG.4 (b) is the fragmentary top view, FIG. 5 is a figure which shows the trace amount extraction state of the contents, and FIG. It is a figure which shows a sealing state.

  The container 1 with an unsealing cap according to the present embodiment can be configured, for example, in a form as shown in FIG. 1, and a container 3 that accommodates various contents such as food and medicine, and the accommodation of the container 3. It is the structure provided with the opening stopper 10 which pours out the content accommodated in the part 3A.

  The container 3 may have any structure as long as it can accommodate various contents as described above. In the present embodiment, the rectangular sheet-like members 3a and 3b are overlapped, and a peripheral portion (upper end portion) indicated by hatching is overlapped. 4 and the side edges 5 and 6 and the lower end (not shown) are thermally welded by a heat bar or the like, thereby forming a container body that defines a container 3A for housing the contents. In this case, the sheet-like members 3a and 3b are made of a synthetic resin sheet (plastic film) having flexibility, for example, polyethylene or polypropylene so as to be easily welded. On the side, it is preferable to be composed of a so-called composite layer in which nylon, aluminum foil, and the like are laminated so as to enhance the barrier property (gas barrier property and light shielding property) against the contents. When the lower end portion is welded, the container may be configured as a three-dimensional body by welding so that the bottom portion is formed.

  In the container structure having the above-described structure, the opening plug 10 is interposed when the upper end portion 4 is welded. The unsealing plug 10 includes a welding portion 11 having a substantially boat-shaped cross section, a cylindrical portion 13 formed in a substantially cylindrical shape (cylindrical shape), and a cylindrical shape so that the stacked sheet-like members 3a and 3b are welded. A plug body portion 15 that is integrally formed in the distal end opening region of the portion 13 and that is separable (can be torn) from the tubular portion 13.

  The tubular portion 13 is formed with a communication portion 13a that is hollow inside and communicates with the housing portion 3A of the housing body 3 through the welded portion 11, and the tubular portion is formed in the upper opening region thereof. A plug body 15 that can be cut to open 13 is connected. In this case, the tubular portion 13 and the plug body portion 15 are connected via a thin-walled portion (cut portion) 14 formed along the inner periphery of the opening end surface 13b of the tubular portion 13. By cutting the thick portion 14, the plug portion 15 is configured to be torn from the tubular portion 13.

  Moreover, the said cylindrical part 13 has predetermined length in the axial direction, and the step part 13c is formed in the upper end side. That is, the step portion 13c forms a small-diameter portion 13d having a small inner diameter on the upper side, and an enlarged-diameter portion 13e having a slightly larger diameter than the small-diameter portion on the lower side.

  The plug body portion 15 separated from the tubular portion 13 by cutting the thin-walled portion 14 is inserted again into the opening of the tubular portion 13 so that the contents can be resealed. It is configured. The plug portion 15 includes an insertion portion 15A that is inserted into the cylindrical portion 13, and an exposed portion 15B that is exposed to the outside without being inserted into the cylindrical portion 13, and these are configured in a solid shape. (Considering moldability and the like, a recess or a through hole may be partially formed).

  The insertion portion 15A has a bottomed structure, and when re-sealing, the diameter gradually decreases downward from the thin-walled portion 14 so as to be easily inserted into the opening of the cylindrical portion 13. A tapered surface 16 is formed. In addition, the insertion portion 15 </ b> A is formed with a sealing projection 17 that is in close contact with / separated from the inner surface of the cylindrical portion 13 when the insertion is performed in the cylindrical portion 13. This sealing projection 17 is formed to protrude over 360 ° on the outer surface of the fitting portion 15A above the thin-walled portion 14 to be cut, and against the small-diameter portion 13d above the stepped portion 13c. As a result, the sealing function is exerted in close contact (see FIG. 6), and the enlarged diameter portion 13e below the stepped portion 13c is spaced apart and the flow path D is formed between the inner surface. (See FIG. 5).

  Further, a guide is provided in the fitting portion 15 </ b> A so as to be in close contact with the inner surface of the tubular portion 13 and closer to the opening side (opening side when fitted into the tubular portion) than the sealing projection 17. A projecting portion 18 is formed. More specifically, the guide protrusion 18 pushes the insertion portion 15A into the tubular portion 13 to the maximum extent (this push-in position is such that the flange 20 described later contacts the opening end face 13b as shown in FIG. Is specified to be within the range of the small-diameter portion 13d), and is formed to protrude over 360 ° on the outer surface of the insertion portion 15A, and the guide protrusion 18 is formed, so that the insertion is performed. When the portion 15A is inserted, a gap G is formed between the outer surface of the insertion portion 15A and the tubular portion 13 (small diameter portion 13d). In addition, a notch 18 a is formed in a part of the guide protrusion 18 so that the contents can flow in the gap G.

  The exposed portion 15B is integrally formed with the insertion portion 15A, and even if the insertion portion 15A is pushed into the cylindrical portion 13, it becomes a portion exposed to the outside. For this reason, the exposed portion 15B includes a flange 20 that comes into contact with the opening end surface 13b of the tubular portion 13 when the fitted portion 15A is inserted and pushed into the tubular portion 13. A notch portion 20a is formed in a part of the rear surface side of the flange 20 so that the contents can be poured into and out of the contacted opening end surface 13b.

  In this case, as shown in FIG. 4B, the notch 20a of the flange 20 is preferably formed on the same line as the notch 18a formed on the guide projection 18. The flange 20 is formed with a protruding portion (beak-shaped protruding portion) 20A that protrudes in the radial direction corresponding to the position where the notch portion 20a is formed, and also on the opening end surface 13b. Correspondingly, it is preferable to form a protrusion 13b 'on the receiving side. Further, in the plug body (exposed portion 15B), as shown in the figure, an operation that projects in the radial direction so that the plug body can be easily lifted from the cylindrical portion (so that it can be easily cut). It is preferable to form the piece 22 in advance. That is, by forming such an operation piece 22, it is possible to easily cut the plug portion 15 from the tubular portion 13 at the thin-walled portion 14 by pulling up this portion. It becomes.

  About the opening stopper 10 comprised as mentioned above, it is possible to integrally mold the welding part 11, the cylindrical part 13, and the plug part 15 with resin, for example, polyolefin, such as polyethylene.

Next, an effect | action and effect of the above-mentioned container 1 with an opening stopper are demonstrated.
First, the operation piece 22 is gripped and this part is pulled up, so that the plug body 15 is cut at the thin-walled portion 14 and the plug body 15 is cut off from the tubular portion 13. In this case, it is preferable to further reduce the thickness of the portion where the tearing force acts when the operation piece 22 is pulled up so that the thin-wall pressure portion 14 can be easily cut.

  By cutting the plug portion 15 along the thin-walled portion 14, the contents stored in the container can be poured out through the communication portion 13 a of the tubular portion 13. Then, the cut plug body portion 15 can re-seal the contents by fitting the fitting portion 15 </ b> A into the cylindrical portion 13. In this case, as shown in FIG. 5, when the flange 20 formed on the plug body 15 (exposed portion 15B) is brought into contact with the open end surface 13b of the tubular portion 13, the container 3 is shown as indicated by an arrow. A minute pouring path is secured between the housing portion 3A and the contents can be dispensed in a small amount. That is, since the sealing projection 17 is positioned below the stepped portion 13c, a flow path D is formed between the tip of the sealing projection 17 and the inner surface of the enlarged diameter portion 13e. It flows through the path D to the notch 18a formed in the guide protrusion 18 above the path D, and further through the gap G formed by the guide protrusion 18 and the notch 20a formed in the flange 20. It is possible to pour out to the outside.

Such pouring from the notch 20a can be made a minute amount as compared with the case where the plug body portion 15 is removed and the pipe portion 13 is directly poured out, and the plug body portion 15 is simply placed in the tube. It is possible to easily perform the operation by only deeply inserting into the shape portion 13. That is, after the plug body 15 is resealed, a small amount of dispensing operation can be easily performed with an opening stopper having a simple structure.
As described above, the cutout portion 20a is formed in the beak-shaped protruding portion 20A, so that it is easy to grasp the position where the content is to be dispensed in a minute amount, and the minute amount dispensing operation can be performed smoothly. It becomes like this. Further, since the protruding portion 13b 'is formed on the opening end face 13b side so as to correspond, the liquid dripping hardly occurs and the insertion direction at the time of resealing can be clarified. Furthermore, since the notch 20a formed in the flange 20 and the notch 18a formed in the guide projection 18 are formed on the same line, the dispensing flow path from the accommodating portion 3A is linear. As a result, a small amount of content can be smoothly dispensed.

  Then, as shown in FIG. 6, when the above-described fitting portion 15 </ b> A is pulled up with respect to the tubular portion 13 and the sealing projection 17 is in close contact with the small diameter portion 13 d of the tubular portion 13, the contents can be sealed. It becomes possible. Of course, if the plug body 15 is further removed from the tubular portion 13 in this state, a normal dispensing operation can be performed via the tubular portion 13.

  Next, a second embodiment of the container with an opening stopper according to the present invention will be described with reference to FIGS. In the embodiments described below, the same components as those in the above-described embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the present embodiment, a deformation region that can be easily elastically deformed in the radial direction is formed in an intermediate portion of the cylindrical portion 13. Specifically, such a deformation region is configured by partially forming a thin portion 13h on the side surface of the cylindrical portion 13, and as shown in FIG. When the contents can be sealed and the contents can be sealed, and the internal pressure of the accommodating portion 3A of the accommodating body 3 is increased and the contents flow to the portion of the sealing projection 17 with a certain pressure, as shown in FIG. The flow path D is formed by being elastically deformed so as to spread outward in the radial direction.

  The position where the thin wall portion 13h is formed is such that when the plug body portion 15 (insertion portion 15A) is inserted into the tubular portion 13 and the flange 20 is brought into contact with the opening end surface 13b of the tubular portion, a sealing protrusion is formed. The part 17 is set at a position where it can be in close contact (the plug part 15 is configured in the same manner as in the above embodiment). Thus, in this embodiment, it is possible to seal the contents and dispense a small amount without moving the position of the plug portion 15 up and down as in the first embodiment described above. . In addition, when a small amount of content is dispensed, the internal pressure of the accommodating portion 3A can be increased by, for example, holding the accommodating body 3 and applying a pressing force, or tilting the accommodating body 3.

  Moreover, in this embodiment, although the cylindrical part was deform | transformed, you may form the partial front-end | tip of the protrusion 17 for a seal | sticker thinly other than that, for example. That is, a structure in which a sealing state is maintained when no internal pressure acts on the sealing projection 17 and elastic deformation is performed when the internal pressure acts on the sealing projection 17 to secure a flow path may be employed. .

  As mentioned above, although embodiment of this invention was described, this invention can be suitably deformed besides embodiment mentioned above. For example, the position where the unsealing plug 10 is attached to the container 3 can be appropriately modified. Moreover, the plug part 15 should just be a structure which can be inserted in the cylindrical part 13 and can be resealed, and it can change variously about the shape, the tearing method, etc. FIG. Further, the container 3 may be configured as, for example, a plastic bottle type other than the above-described sheet-like members 3a and 3b.
