Description

  The present invention provides a closed laminate tube having a closed end made of aluminum having a closed portion in which a content outlet is previously closed at one end, and a cap for detachably closing the outlet. The cap is provided with a screwing portion for closing the outlet so as to cover the outlet on the inner side of one end, and the opening is opened by breaking the blocking portion on the inner side of the other end. More specifically, the protrusion includes a pedestal, a rupture rib on the pedestal that breaks the closing portion, and an expansion rib that extends the rupture portion of the closing portion. The breaking rib and / or the expansion rib are related to being larger in diameter than the pedestal.

  Conventionally, tube containers filled with food and drink, pharmaceuticals, quasi-drugs, cosmetics, chemicals, industrial products, and other contents are packed with a closed membrane at one end in advance. There is a closed type laminated tube, etc., which is made by insert molding and attaching a barrier made of aluminum that has a barrier property, and is closed and attached by screwing so as to cover the outlet. Has a free cap. The cap is provided with a pointed and spindle-shaped protrusion that opens the outlet in a recess provided on the opposite side of the threaded portion that can be fitted into the outlet. When removing the contents from the laminate tube for the first time, the cap removed from the closed laminate tube is turned to the other side, the closure membrane of the outlet is pierced with this protrusion, and then the closure membrane is broken. Open the outlet to allow the contents to be taken out (for example, Patent Document 1).

JP 2006-123918 A

As described above, in order to open the outlet of the closed laminate tube and efficiently take out the contents, the base should be made substantially equal to the inner diameter of the outlet and a large hole should be made in the closing membrane. However, in this case, since the diameter of the pedestal is too large, the resistance to spread the closing membrane becomes strong, and conversely, it becomes difficult to open the closing membrane. Therefore, in such a conventional closed-type laminated tube container, the diameter of the pedestal is made smaller by about 0.1 mm to 0.3 mm than the inner diameter of the outlet, so that a large hole cannot be formed in the closing membrane. Therefore, there is a problem that the contents in the container cannot be efficiently taken out from the outlet.
Also, the protrusion of the cap cannot be provided high in order to prevent the cap from protruding from the top surface according to the height of the diaphragm, and such a short protrusion cannot increase the piercing stroke. Therefore, there is also a problem that the closure membrane cannot be easily broken.
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a content provided with a cap that can easily and surely break a closing membrane of an outlet port by using a relatively low protrusion having a height restriction to open a large hole. It is in providing the container excellent in the usability which can take out efficiently.

  For this reason, the invention described in claim 1 is a closed-type laminate tube, in which a throttle body made of aluminum having a closed portion in which a content outlet is previously closed is attached to one end, and the take-off tube. A cap for detachably closing the outlet, and the cap is provided with a screwing portion for closing the outlet so as to cover the outlet on the inside of one end, and on the inner side of the other end. In the container provided with a protruding part for breaking the closing part and opening the outlet, the protruding part has a pedestal, a rupture rib on the pedestal for breaking the closing part, and the closing part And an expansion rib that expands the fracture portion, wherein the fracture rib and / or the expansion rib is larger in diameter than the pedestal.

Further , the breaking rib is characterized in that a vertex of the breaking rib becomes a protruding portion located at a central portion of the protruding portion.

Further , the expansion rib is characterized in that a vertex of the expansion rib is located at a height of a midway portion of the protruding portion.

According to a second aspect of the present invention, in the container according to the first aspect of the present invention, an engagement portion is provided at a concave portion inside the other end of the cap, the outer peripheral position of the concave portion and the outer peripheral position of the throttle body. It is provided.

  According to the first aspect of the present invention, the closed laminate tube, which is formed by attaching a throttle body made of aluminum having a closed portion in which the content outlet is previously closed, is attached to the one end. A cap that detachably closes the cap, and the cap is provided with a screwing portion for closing the outlet so as to cover the outlet on the inside of one end, and the closure portion is broken on the inner side of the other end. In the container provided with a protrusion for opening the outlet, the protrusion includes a pedestal, a rupture rib that breaks the closed portion, and an extended rib that extends the rupture portion of the closed portion, on the pedestal, Since the breaking rib and / or the expansion rib have a larger diameter than the pedestal, when opening the closing part of the outlet, the cap protrusion can be pierced into the closing part and broken with a little force , The piercing resistance to the cap closure Since the closed portion can be easily broken and the broken area and the expanded area can be increased, a large hole can be formed in the closed portion and the outlet can be sufficiently opened. Therefore, a container excellent in usability can be provided.

In addition , since the rupture rib has a protrusion that is located at the center of the protrusion, the rupture rib breaks the closure portion by concentrating the power point on the protrusion and the edge of the three break ribs. Therefore, the puncture resistance to the blocking portion can be reduced. Therefore, it is possible to provide a container with excellent usability that can easily break the closed portion.

In addition , since the apex of the expansion rib is located at the middle part of the protrusion, the expansion rib first continues to break between the breakage part of the closed part where the protrusion part and the breakage rib were easily broken. It is possible to open a large hole in the closed portion by expanding the expansion rib while tearing the rib. Therefore, it is possible to provide a container with excellent usability that can open the closed portion with a sharp cut.

According to the second aspect of the present invention, since the engaging portion is provided in the concave portion inside the other end of the cap, the outer peripheral position of the concave portion and the outer peripheral position of the throttle body, the protruding portion of the cap is removed. When the closure part of the outlet is stabbed, the protrusions of both the cap and the throttle body engage with each other, so that the user can feel a click feeling that the stab of the projection part of the cap to the throttle body is completed. Therefore, a container excellent in usability can be provided.

The best mode for carrying out the present invention will be described below with reference to the drawings.

First, the main body 2 is made of a material such as a flexible film in which an aluminum foil is laminated between a plurality of polyethylene resin layers, and has a shape such as a cylinder or an elliptical cylinder. Fill and close one end by gluing or welding.

  The other end of the main body 2 is made of aluminum having a barrier property, and a diaphragm 5 called a rondel is attached by insert molding or the like. The throttle body 5 is formed in a state in which the content outlet 6 at the tip is previously closed with a closing portion 7 such as a film made of a laminated material in which aluminum foil and plastic are bonded together. Is done. Furthermore, a thread 15 for attaching the cap 3 is formed on the outer peripheral surface of the mouth portion 4.

  Next, as shown in FIGS. 2 to 3, the cap 3 includes a cylindrical threaded portion 8 formed on one inner side (the outlet 6 side) and a protruding portion 9 formed on the other side. In addition, the inner diameter of the cap 3 is preferably within the inner diameter of the main body 2. Further, the cap 3 may be processed to have unevenness or the like for preventing slippage. And this cap 3 may use resin, such as polyethylene, a polypropylene, a polystyrene, ABS (acrylonitrile butadiene styrene) type, for example, and can obtain it by injection-molding those things which are not limited. . The material of the main body 2, the diaphragm 5, the cap 3, and the like in the closed laminate tube type container 1 is a well-known technique described in, for example, the above-described Japanese Patent Application Laid-Open No. 2006-123918, and therefore a detailed description thereof. Is omitted.

  Further, the inner diameter and height of the screwing portion 8 are substantially equal to the outer diameter and height of the mouth portion 4, and the inner surface of the screwing portion 8 is provided with a screw thread 15 provided on the outer peripheral surface of the mouth portion 4. A thread groove 14 to be screwed is formed.

  With the configuration as described above, the cap 3 in which the screwed portion 8 of the cap 3 is screwed into the mouth portion 4 of the main body 2 so that the mouth portion 4 can be detachably closed is the content the main body 2 has. Can be prevented, and the mouth 4 can be protected. The attachment / detachment of the cap 3 to / from the mouth portion 4 is not limited to the above-described screwing between the screw thread 15 and the screw groove 14, and the attachment / detachment mechanism such as a fitting type having an uneven portion or the like is not limited.

  Next, a specific configuration of the protrusion 9 of the cap 3 which is a feature of the present invention will be described. 4 is a plan view of the cap, FIG. 5 is a cross-sectional side view of the cap as viewed in the direction of arrow B in FIG. 4, FIG. 6 is a cross-sectional side view of the cap as viewed in the direction of arrow C, and FIG. FIG.

  As shown in FIG. 2, the protrusion 9 is a bottom in the recess 10 formed on the other side of the cap 3 described above, and is 0.1 mm from the inner diameter of the outlet 6 formed in the center of the cap 3. A pedestal 11 having a diameter of about 0.3 mm, such as a column, and a rib 13 provided on the pedestal 11 and having a diameter larger than the diameter of the pedestal 11 and substantially equal to the inner diameter of the outlet 6. It consists of. Note that the shape of the outlet 6 is not limited to a circle, and may be an appropriate shape such as a triangle or a quadrangle. In that case, the shapes of the base 11 and the screwing portion 8 are also matched to the shape of the outlet 6. Shaped.

  The position of the apex of the rib 13 is a position that does not exceed the height position of the other end of the cap 3. By doing in this way, the injury by the protrusion part 12 can be prevented, and it does not become an obstacle when placing the container 1 upright with the other side of the cap 3 as the bottom.

  The ribs 13 have protrusions 12 at the apex located at the center of the cap 3, and are provided radially at equal intervals around the protrusions 12. As shown in FIG. 4, the rib 13 includes a breaking rib 13 a that breaks the closing portion 7 and an expansion rib 13 b that extends the breaking portion of the closing portion 7. The breaking rib 13 a is centered on the protruding portion 12. 3 are installed at 120 ° intervals. In addition, three expansion ribs 13b are installed at intervals of 120 ° around the protruding portion 12 so as to be positioned between the breaking ribs 13a. Accordingly, the fracture ribs 13a and the extension ribs 13b are arranged radially with the protrusion 12 as the center, and the gap between the fracture ribs 13a and the extension ribs 13b is 60 °. .

  As shown in FIGS. 2 and 5, the three break ribs 13 a have the protruding portions 12 as the apexes of the break ribs 13 a and extend from the apex of the break ribs 13 a to the outside of the outer peripheral portion of the base 11. The provided side has a curve, is wide in side view, and has an area larger than the area of the expansion rib 13b.

  On the other hand, as shown in FIG. 2 and FIG. 6, each of the expansion ribs 13 b has the vertices of the expansion ribs 13 b positioned at the midway height of the projecting portion 12, and the base 11 The side extended to the outer side of the outer periphery of this has a curve, and a side surface has an area smaller than the area of the fracture | rupture rib 13a. Therefore, the height of the side of the expansion rib 13b is lower than the height of the side of the breaking rib 13a. As described above, both the breaking rib 13a and the extension rib 13b have a larger diameter than the pedestal 11, and either the breaking rib 13a or only the extension rib 13b may have a larger diameter than the pedestal 11. Furthermore, as described above, both the breaking rib 13a and the expanding rib 13b have a diameter substantially equal to the inner diameter of the mouth of the outlet 6, and either the breaking rib 13a or only the expanding rib 13b is removed. It is good also as a diameter substantially equal to the internal diameter of 6 ports.

  The projections 9 such as the protrusions 12, the breaking ribs 13 a and the expansion ribs 13 b are formed at the same time as the cap 3 is formed.

  Here, the contents are filled from the bottom (one end) of the main body 2, and the bottom 4 is welded with a heat seal, an ultrasonic seal, or the like, so that the outlet 4 is blocked by the closing portion 7 in advance. When the container 1 (unused product) whose contents are sealed in the main body 2 is used for the first time, the cap 3 is first screwed into the outlet 4 of the main body 2 by rotating the cap 3. The cylindrical portion 8 is released from the screw fitting, the cap 3 is detached from the main body 2, and the direction of the cap 3 is changed so that the protruding portion 9 of the cap 3 faces the outlet 4.

  Next, the protruding portion 12 of the protruding portion 9 is pierced into the closing portion 7 aiming near the central portion of the closing portion 7. At this time, the protrusion 10 is positioned in the vicinity of the central portion of the closing portion 7 by fitting the recess 10 to the outlet 6.

  Then, after the vicinity of the central portion of the closing portion 7 is easily broken by the protruding portion 12, the breaking rib 13 a comes into contact with the surface of the closing portion 7 by pressing the cap 3 toward the main body 1 side. At this time, although the power point of the projecting portion 12 is dispersed on the three sides of the three breaking ribs 13a, it concentrates on the three sides, so that the surface of the closing portion 7 located on the breaking rib 13a is the breaking rib. It is easily ruptured so as to have an approximate shape 13a (the shape of the rupture varies depending on the material of the sealing material, how to apply force, etc.).

  Next, the cap 3 is further pressed toward the main body 2, so that the expansion rib 13 b comes into contact with the surface of the closing portion 7. At this time, each expansion rib 13b is positioned on the closed portion 7 between the portions broken by the breaking rib 13a as described above. Therefore, the expansion rib 13b is pressed by the breaking rib 13a by the pressing of the expansion rib 13b. The closing part 7 between the broken parts is pushed into the main body 2 side. Therefore, these expansion ribs 13b can expand the fractured portion of the closing portion 7 with certainty.

  As a result, as shown in FIG. 7, the opening area a of the blocking portion 7 can be reliably increased, and the outlet 6 can be completely opened. Therefore, with the above configuration, when opening the closing portion 7 of the outlet 6, the protruding portion 9 of the cap 3 can be pierced into the closing portion 7 and broken with a little force. Therefore, the closed portion 7 can be easily broken and the broken area and the expanded area can be increased. Therefore, a large hole can be made in the closed portion 7 and the outlet 6 can be sufficiently opened. For this reason, since the user can fully take out the contents from the outlet 6 by pressing the container 1, the usability of the container 1 is improved.

  Furthermore, the fracture ribs 13a and the expansion ribs 13b are alternately provided radially with the breakage ribs 13a at the intervals of 120 ° and the expansion ribs 13b at the intervals of 120 °, and the fracture ribs 13a and the expansion ribs are formed radially. By providing the ribs 13b at intervals of 60 °, the closed portion 7 can be efficiently broken and expanded by the minimum necessary ribs, and the outlet 6 can be completely opened, so the molding cost of the cap 3 can be reduced. be able to.

  In addition, the break rib 13a has a protrusion 12 located at the center of the protrusion 9 at the apex of the break rib 13a, so that the emphasis is placed on the apex of the protrusion 12 and the sides (edge portions) of the three break ribs. Since the blocking portion 7 is broken by concentrating the blocking rib 7, the piercing resistance to the blocking portion 7 can be reduced, and the expansion rib 13b has the apex of the expansion rib 13b at the height of the middle portion of the protruding portion 12. Since it is located, first, between the fractured parts of the closed part 7 easily broken by the projecting part 12 and the fractured rib 13a, it is expanded by the extended rib 13b while tearing by the fractured rib 13a, and the closed part 7 is surely secured. And you can easily make large holes.

  The container of the present invention may be provided with a means for obtaining a click feeling in the user's hand so that it can be seen that the piercing is completed when the protruding portion 9 of the cap 3 is pierced into the outlet 6. it can. FIG. 8 is a schematic side view of the throttle body and the cap showing an example of the internal structure when the protrusion of the cap is pierced into the outlet of the throttle body. In this case, as shown in FIG. 8, for example, a protrusion 16 provided near the bottom of the outer periphery of the recess 10 of the cap 3 and a protrusion 17 provided near the upper end (outlet 6) of the outer periphery of the throttle body 5 An engaging portion 18 is formed.

  Then, when the protrusion 9 of the cap 3 is pierced into the outlet 6 in order to open the closing portion 7, the protrusion 16 of the recess 10 of the cap 3 gets over the protrusion 17 of the diaphragm 5 and engages both. Thus, the user can obtain a click feeling in his / her hand, and can confirm that the protrusion 9 is pierced into the closing part 7 with certainty.

  In addition, although installation of the engaging part 18 is not limited to the position mentioned above and is not shown in figure, for example, the protrusion 16 is near the upper end part of the outer periphery of the recess 10 in the cap 3 and the protrusion 17 is the outer periphery of the diaphragm 5. In this case, the same effect as described above can be obtained.

  In addition, this invention is useful for the container filled with foodstuffs, cosmetics, etc., such as a liquid form, a paste form, and foam form.
