Description

  The present invention relates to an easy-opening pouring tool attached to the mouth of a container filled with the contents, and more specifically, the contents are scattered when opened while sufficiently securing the opening of the pouring cylinder. In addition, the present invention relates to an easy-opening dispensing tool that can be opened even by relatively weak women and elderly people.

  As shown in FIGS. 9 and 10, the cap with a spout is usually provided with an annular score 52 along the inner periphery of the spout tube 50 on the closing wall 51 in the spout tube 50, and an inner side of the annular score 52 is provided. In the closed wall 51, a score tearing tension portion 53 is provided adjacent to the annular score 52 and symmetrically with respect to the center line thereof. By pulling the tension portion 53 with fingers, the annular score 52 is provided. The closing wall 51 on the inner side of the tear is removed, and the dispensing tube 50 is opened.

  This cap with a spout tears the annular score 52 by pulling the pulling portion 53 in the radial direction and upward from the base end portion when opening, but the annular score 52 faces in two circumferential directions (left and right). As a result, the tensile force at the beginning of tearing spreads and becomes high, and there is a risk that it cannot be opened easily by women and women who are relatively weak. Under such circumstances, the following caps with easy opening spouts are provided for the purpose of easy opening.

  As shown in FIG. 11, the easy-opening pouring tool is provided with a pulling portion 53 on the closing wall 51 in the pouring tube 50, and a “54” -shaped score 54 is provided on the closing wall 51. Includes a first score 54 a that is annularly formed on the closing wall 51 along the inner periphery of the pouring cylinder 50, a second score 54 b that extends from the first score 54 a toward the proximal end portion 53 a of the pulling portion 53, The second score 54b and the third score 54c are composed of the third score 54c extending from the second score 54b and curved so as to surround the proximal end portion 53a of the tension portion 53. And the second score 54b is substantially parallel to the pulling direction of the pulling portion 53 from the vicinity of the center, and the first bending portion 55 has a straight portion at a different angle with respect to the center line. Through The third score 54c is connected to the score 54a and extends from approximately the center toward the center of the closing wall 51, and is largely bent at the second curved portion 57 before the terminal end 56. The second curved portion 57 is the second curved portion 57. The arc 54 has a smaller radius of curvature than the arc of the first curved portion 55 of the score 54b.

  Accordingly, when the pulling portion 53 is pulled with a finger, the second score 54b and the third score 54c start to tear from the base end portion 53a side, and the tear of the second score 54b proceeds toward the first score 54a. The tearing of the third score 54c also proceeds toward the second bending portion 57 on the terminal end 56 side. Since the second bending portion 57 is bent so as to be greatly bent, when the tear of the third score 54c smoothly proceeds and reaches the end 56, the tear of the second score 54b also reaches the first score 54a. After that, only the first score 54a tears, and the closing wall 51 is removed before the opening is completed (see, for example, Patent Document 1).

  Further, as shown in FIG. 12, the easy-opening pouring tool includes a cutout portion 60 provided with small projections 58 and 59 having a narrow width on the closing wall 51 on the inner side of the pouring tube 50. An annular score 61 is formed around the cutout portion 60 on the inner side of 51, a convex rib 62 is provided on the score 61 at the base portion of the small projection portion 58 on the outer closing wall 51, and a tension portion The base end portion 53 a of 53 is connected to the small protrusion 58 inside the score 61. Accordingly, when the pulling portion 53 is pulled with a finger, the score 61 is torn from the small projection 58 side of the base end portion 53a, and the tear is temporarily stopped by the rib 62 on the small projection 58, and the small projection 5 The air enters through the narrow opening of the sheet to prevent the contents from being scattered, and the small scored portions 58 and 59 of the annular score 61 are formed at the beginning and end of tearing, so that it can be opened even with a weak force. Yes (see, for example, Patent Document 2).

Utility Model Registration No. 2600445 Japanese Patent Laid-Open No. 11-227816

When the pulling portion 53 is pulled with a finger, the second score 54b and the third score 54c start to tear from the base end portion 53a side, and the second score 54b is torn. Since the third score 54c progresses toward the first curved portion 55 and the tear of the third score 54c also proceeds toward the second curved portion 57, the closed wall 51 is cut in a band shape, and the tear of the second score 54b is the first curved portion. The first score 54a may be reached via the portion 55, and the third score 54c may also tear after reaching the end 56 via the second bending portion 57, and only the first score 54a may be torn. The first score 54a that is torn and the third score 54b and the first score 54a that have already been torn together are combined, and the closed wall 51 is still cut into a band shape. In Opening is finished and removed by.
That is, since the second score 54b and the third score 54c in the vicinity of the base end portion 53a at the beginning of tearing are acute-score shapes, the pulling force is not dispersed so much and the closing wall 51 is torn into a strip shape with a relatively small force. It can be done. However, if the pulling portion 53 is pulled in the radial direction and upward, the second score 54b may derail and reach the first score 54a. In this case, it becomes difficult to break the first score 54a in the circumferential direction, the third score 54c is also derailed, and the portion surrounded by the second score 54b and the extension line of the third score 54c and the first score 54a There is a risk of breaking and removing. Further, the shape of the closed wall 51 cut out in a band shape is restored, and the contents are scattered. It is difficult to suppress the scattering.

  Moreover, since the easily openable pouring tool of patent document 2 is provided with the cut-out part 60 which provided the small protrusion parts 58 and 59 with a partly narrow width on the closing wall 51 of the pouring cylinder 50, the pulling part 53 is provided. When the finger is pulled, the score 61 is torn from the side of the small protrusion 58 of the base end 53a, and the tear is temporarily stopped by the rib 62 to prevent the contents from being scattered. Since the small protrusions 58 and 59 are narrow (so-called acute-score shape), the pulling force at the beginning of tearing is not so dispersed as in Patent Document 1, and it is excellent in that it can be opened even with a weak force. Yes. However, since the cutout portion 60 serving as the opening of the dispensing tube 50 has small projections 58 and 59 that are partially narrow, the opening of the dispensing tube 50 is narrowed accordingly, and the content is high in viscosity. If so, the contents will not be poured out smoothly.

  Therefore, the purpose of the present invention is to make the shape of the tear start portion an acute angle in order to make it easier to open the dispensing cylinder, and the opening is not narrowed, or the contents are not scattered at the time of opening, The object is to provide an easy-opening dispensing tool that can be opened even by relatively weak women and women and elderly people.

The present invention has been proposed in order to achieve the above object, and is characterized by having the following configuration.
That is, according to the present invention, there is provided a pouring tool having a mounting portion that can be attached to the mouth portion of a container, a closing wall that covers the mouth portion of the container, and a pouring tube for contents, and the closing wall includes the pouring portion. The inner surface of the lower end of the tube is covered with an annular flange portion extending inward from the lower end of the pipe and an opening planned portion formed on the inner side of the flange portion. The opening-forming score is formed from an annular outer score provided at an inner end of the flange portion, an arc-shaped inner score positioned inwardly of the outer score, and an outer score. It consists of a radial contact score extending inwardly score, the inner score, if the located above or below the outer score, the opening portion to be provided with a pulling portion for scoring tear extending upward co The tension portion is provided between the inner score and the outer score, the contact score is engraved on one side of the base end portion of the tension portion, and the inner score is directed from the contact score toward the tension portion. Thus, an easy-opening dispensing tool is provided, which is formed by engraving at a predetermined angle in the circumferential direction.

  Moreover, according to this invention, the shape of the said opening plan part is provided with the said easily openable extraction tool which is circular.

  Moreover, according to this invention, the said circumferential direction predetermined angle of the said inside score is the said easily openable extraction tool which is 120 to 270 degree | times from the said contact score.

  The action by the first problem solving means is that when the score tearing tension portion is pulled, the force concentrates on the corner of the outer score and the radial communication score in the opening forming score. Start cutting the contact score, then the inner score is also cut with the outer score to a predetermined angle in the circumferential direction, and the closing wall is cut into a band to the predetermined angle, but then only the outer score is cut to remove the planned opening of the closing wall. The dispensing tube can be opened.

When the inner score is positioned above the outer score, after pulling the score tear tension part to tear a part of the outer score and the radial communication score, the remaining outer score and upper The inner score in the area is torn, and the opening force can be concentrated and cut off without dispersing the tearing force. Even when the inner score is positioned below the outer score, the object of the present invention can be achieved although the above effect is slightly reduced.

The operation of the second problem solving means can form a circular opening planned portion along the pouring cylinder according to the cross-sectional shape of the pouring cylinder, that is, form a sufficiently large opening planning portion. can do.

The action by the third problem solving means is that the arc-shaped inner score of the closed wall is cut out in a band shape with the outer score from 120 degrees to 270 degrees in the circumferential direction from the contact score toward the pulling portion side. After that, it is possible to cut only the outer score carved on the closed wall and cut the planned opening.

  The easy-opening dispensing tool of the present invention does not disperse the opening force but concentrates on the corners of the outer score and the radial contact score, so that it can be easily opened even by relatively weak women and elderly people. In addition, there is no limit condition for engraving the outer score on the planned opening on the closed wall in the dispensing tube, and it can be set freely, so the opening of the dispensing tube is not narrowed, and it is further cut into a strip shape. Since the closing wall is also limited to a predetermined angle in the circumferential direction, its shape restoring force is weak, and there is an effect that the contents are not scattered when opened.

  Further, the easy-opening pouring tool of the present invention can provide a maximum opening scheduled portion having an opening in accordance with the cross-sectional shape of the pouring cylinder on the closing wall in the pouring cylinder. There is an effect that even things can be poured out smoothly.

  In addition, since the easily openable dispensing tool of the present invention has a weak shape restoring force due to the closed wall cut into a band shape, there is an effect that the contents are not scattered at the time of opening.

Furthermore, since the inner score and the outer score are not on the same plane and either one is located above or below, the easy-opening dispensing tool of the present invention can easily cut the planned opening portion and easily open it. Further, there is an effect that the mold formability is further improved.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  In the drawings, 1 is an easy-opening pouring tool, and this easy-opening pouring tool 1 (hereinafter simply referred to as “cap 1”) can be attached to the mouth 3 of the container 2 and the container mouth 3. The closing wall 5 and the content extraction tube 6 are covered, and the closing wall 5 covering the inner surface of the lower end of the extraction tube 6 is an annular flange portion 29 extending inwardly from the lower end of the extraction tube 6. And the planned opening portion 7 formed inside the flange portion 29, and the planned opening portion 7 is formed to be tearable from the flange portion 29 by the opening forming score 8. The planned opening portion 7 is provided with a score tearing tensile portion 9 (hereinafter simply referred to as “the tensile portion 9”) extending upward, and the opening forming score 8 is engraved in the annular flange portion 29 of the closing wall 5. A circular outer score 10, an arcuate inner score 11 positioned inward of the outer score 10, and a radial contact score 12 (hereinafter simply referred to as “contact score 12”) from the outer score 10 to the inner score 11. The tension portion 9 is provided between the inner score 11 and the outer score 10, and the connection score 12 is engraved on one side of the base end portion 9a of the tension portion 9, and the inner score 11 Is engraved at a predetermined angle α in the circumferential direction from the contact score 12 toward the pulling portion 9 side.

  The container 2 is not particularly limited as long as it can be attached and sealed to the mouth 3 by attaching or screwing the attachment part 4 of the cap 1 to the mouth part 3 or by welding to the pouch container or paper container. Any type or material may be used. In the container 2 of the first embodiment, it is assumed that the cap 1 can be attached to the mouth portion 3 by plugging the cap portion 1 with the mounting portion 4 of the cap 1.

  The cap 1 has a top surface 20 and a skirt wall 21 that hangs down from the periphery of the top surface 20. The top surface 20 is provided with the pouring tube 6, and screws 22 are engraved on the outer peripheral surface of the upper half 21a of the skirt wall 21 so that an upper lid 23 which will be described in detail later can be screwed on and off. An outer wall 24 is formed so as to project outward from the outer peripheral surface of the intermediate portion 21, and this outer wall 24 forms the mounting portion 4 together with the lower half portion 21 b of the skirt wall 21. In addition, after providing the convex part 25 in the inner peripheral surface of the lower end part of the outer side wall 24, and plugging the cap 1 in the container mouth part 3, this cap 1 never falls out of the container mouth part 3 absolutely. Yes.

The upper end of the pouring cylinder 6 extends outward and is conveniently formed for pouring the contents, and an opening planned portion 7 is provided at the inner end of the flange portion 29 of the closing wall 5 at the bottom. As shown in FIG. 1, the planned portion 7 includes a lower top plate portion 30 located above the flange portion 29 and an upper top plate portion 31 located above the lower step top plate portion 30. The closing wall is also horizontal. Further, the score tearing pulling portion 9 is provided on the upper surface of the lower top plate portion 30 as shown in FIGS.
As shown in FIGS. 5 to 8, the flange portion 29 and the lower top plate portion 31 are connected by the annular outer score 10 of the opening forming score 8, and the lower top plate portion 30 and the upper top plate portion 31 are 4, the arcuate inner score 11 having a predetermined circumferential angle α (180 degrees in the first embodiment) from the contact score 12 toward the tension portion 9 and the remaining portion as shown in FIGS. Further, the outer score 10 and the inner score 11 are connected to each other by a connecting portion 13 that forms a radial contact score 12 extending radially toward the center of the planned opening portion 7 as shown in FIGS. Thus, the sealability before opening is maintained, and the opening is facilitated.

  In the first embodiment, the inner score 11 has a predetermined circumferential angle α of 180 degrees. However, the inner score 11 is not limited to this, and may be 120 degrees to 270 degrees from the contact score 12. Even if it cuts out in a strip shape and then cuts only the outer score 10 and cuts the planned opening portion 7, the shape restoring force by the lower top plate portion 30 of the closed wall 5 cut out in the strip shape is weak, so the contents are exposed to the outside at the time of opening. There is no scattering.

In the present invention, the formation positions of the inner score 11 and the outer score 10 are not on the same plane, and either one is located above or below.
When the inner score 11 is positioned above the outer score 10 , after opening, a part of the outer score 10 and the contact score 12 are torn and then the remaining outer score 10 and the inner score 11 above are removed. The opening portion 7 is cut out by concentrating the tearing force without dispersing. Therefore, it is possible to cut the opening scheduled portion 7 facilitates, Ri of easily opened, yet, would that molding property is superior. Moreover, contrary to the above, if the inner score 11 is positioned lower than the outer score 10, although openability and molding property is lowered slightly, it is possible to perform sufficiently the object of the present invention described above .

  The opening forming score 8 of the cap 1 is formed as described above, and the planned opening portion 7 can be easily cut out, so that the opening is easy. 6, that is, the shape of the planned opening portion 7 is not restricted in order to facilitate opening, so the similar shape is, of course, the shape of the planned opening portion 7 can be freely determined. I can do it. Therefore, even if the contents of the container 2 are high in viscosity, the contents can be smoothly poured out from the pouring cylinder 6 and the amount of the contents taken out from the pouring cylinder 6 is maximized. It becomes possible to do.

  As described above, the tension portion 9 is provided between the inner score 11 and the outer score 10, that is, on the lower top plate portion 30, and on one side of the base end portion 9a of the tension portion 9, FIGS. The contact score 12 is located as shown in FIG. The pulling portion 9 is composed of a support 32 and a finger ring 33 extending from the upper part of the support 32, and when opening the finger, the finger ring 33 is hung and lifted to cut out the opening 7 and open the opening. is there. Note that reference numeral 34 in FIG. 1 denotes a finger slipper.

  The upper lid 23 includes a top plate 26 and a side wall 27 that hangs down from the peripheral edge of the top plate 26, and an inner ring 28 that hangs on the top plate 26 from now on and abuts against the inner peripheral surface of the dispensing tube 6. And a screw 28 screwed into a screw 22 carved on the outer peripheral surface of the upper half 21a of the skirt wall 21 is formed on the inner peripheral surface 27a of the side wall 27. The upper lid 23 protects the bare portion of the dispensing tube 6 from external contamination before opening, protects the exposed portion of the dispensing tube 6 and the inside of the container 2 from external contamination even after opening, and the contents of the container 2 This prevents leakage to the outside.

Next, a method for using the easy-opening dispensing tool 1 having the above-described configuration will be described.
First, the cap 1 is closed by screwing the upper lid 23 to the cap 1, and after the contents are filled in the container 2, the cap 1 is attached to the mouth 3 of the container 2, that is, the container mouth 3 is The mounting part 4 of the cap 1 is applied and stoppered to seal the inside of the container 2 (see FIG. 3). Then, if necessary, the container 2 with the cap 1 with the top lid 23 is packaged to obtain a final product.

  When the final product is consumed, at least a portion of the cap 1 is bare, and the upper lid 23 can be opened from the cap 1. Then, when the upper lid 23 is unscrewed, the pulling portion 9 is bare, and the finger ring 33 is lifted with fingers, the force concentrates on the outer score 10 of the opening forming score 8 and the corner portion 35 of the contact score 12. The outer score 10 and the contact score 12 are started to be cut from the corner portion 35, and then the inner score 11 is also cut together with the outer score 10 to a predetermined angle in the circumferential direction, for example, 180 degrees, so that the lower top plate portion 30 of the closed wall 5 is 180 degrees. However, since there is no inner score 11, only the outer score 10 is to be cut, the planned opening portion 7 in the closed wall 5 is removed, and the dispensing cylinder 6 is opened.

  Then, a necessary amount of the contents in the container 2 can be poured from the dispensing cylinder 6 into a desired container or the like. If the contents remain in the container 2 after pouring the contents, the upper lid 23 is screwed onto the cap 1 and the inner ring 28 is fitted to the inner peripheral surface of the dispensing cylinder 6. The contents of the container 2 are sealed so as not to leak. Thereafter, the same operation described above is repeated until the contents of the container 2 are used up.

  As mentioned above, although Example 1 of this invention was demonstrated, a specific structure is not limited to this, For example, it can apply also to the pouring tool attached to the container comprised with the film, and a stopper, and also the summary of this invention It should be understood that changes without departing from the scope can be made as appropriate. In addition, in the first embodiment, any of the closed walls of the lower opening top plate portion 30 including the lower step top plate portion 30 located above the flange portion 29 and the upper step top plate portion 31 located above the lower step top plate portion 30 is also horizontal. However, it may be an inclined surface.

  The easy-opening dispensing tool of the present invention can be opened even by relatively weak women and elderly people, but when the viscosity of the contents of the container is high or the amount of contents to be taken out is to be maximized, Its availability becomes extremely high.
