Description

[Technical field]

[0001] The present invention relates to a technology for sealing the mouth of a container, and more particularly to a one-piece cap structure with an opening history band formed of a synthetic resin, and a method for setting the cap structure on a container body. [Background technology]

[0002] Bottle containers such as PET bottles and paper cartons with spouts that can be opened and closed are widely used as beverage containers for water, tea, soft drinks, etc. As caps for sealing the container mouths of these containers, synthetic resin caps formed into a desired shape by injection molding of resin, for example, are used.

[0003] There are several types of synthetic resin caps, including a type in which the cap is attached and fitted to the mouth of a container, and a type in which the cap is screwed into a screw portion formed on the outer peripheral surface of the cylindrical side wall of the mouth of the container by screw engagement. In recent years, pouches capable of containing jelly-like foods and the like using a flexible sheet have also been widely used. For the stopper of such a pouch, the mouth of the container is formed by a spout heat-sealed to the container body, and the mouth of the container is opened or closed using a synthetic resin cap.

[0004] Here, as exemplified in Patent Document 1, a cap-integrated spouting tool has been proposed in which the above-mentioned spout and cap are integrated during manufacturing. With such a cap-integrated spouting tool, the spout and cap, which are molded separately as two pieces during manufacturing, can be manufactured at the same time, which makes it possible to simplify the production line and reduce costs.

[0005] [Patent Document 1] JP 2008-56271 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, the techniques including those described in the above patent documents still do not meet the needs of the market, and at least the following problems remain. In other words, although the cap-integrated dispensing device proposed in the above-mentioned Patent Document 1 certainly achieves cost reduction, it does not have a tamper-evident band (hereinafter also referred to as a "TE band") which makes it relatively easy to prove the opening history, and it can be said that there is room for improvement in terms of making the above-mentioned opening history easier to visually confirm.

[0007] One of the objects of the present invention is to provide a one-piece cap structure with an opening history band in which the cap and container mouth (spout, etc.) are integrated, which improves the visibility of the opening history while also simplifying the production line and reducing costs, and to provide a method for setting the same. [Means for solving the problem]

[0008] In order to solve the above problems, one embodiment of the present invention provides a one-piece cap structure with an opening history band, characterized in that it comprises: (1) a container mouth portion fixed to a container body and having an opening through which contents stored in the container body can be poured out; a top plate portion and a sealing tube descending axially from the top plate portion, and a top lid portion including a lower end of the sealing tube integrally connected to the upper edge of the opening via a first breakable breaking portion; a band extending upward from the top plate portion and connecting to the top plate portion; and a TE band portion connected to the band portion.

[0009] Furthermore, in the one-piece type opening history band-equipped cap structure described above in (1), (2) it is preferable that the band body is flexible so as to attach the TE band portion to the container mouth portion, and is arranged intermittently in a plurality of parts along the circumferential edge of the top plate portion.

[0010] In addition, in the one-piece type opening history band-equipped cap structure described above in (2), (3) it is preferable that the band has a second breaking portion formed along the width direction, which can be broken at the time of initial opening.

[0011] Furthermore, in the one-piece type cap structure with opening history band described in (3) above, (4) the container mouth portion includes a cylindrical portion in which the opening is formed, and a cap portion capable of engaging with the TE band portion is provided on the outer peripheral surface of the cylindrical portion, and it is preferable that the second breaking portion is positioned above the cap portion when the TE band portion is suspended and supported by the band below the top plate portion.

[0012] Furthermore, in the one-piece type opening history band cap structure described above in (2), (5) it is preferable that a first rib extending along a direction perpendicular to the width direction is formed on the inner surface of the band that lifts and supports the TE band portion above the top plate portion.

[0013] In addition, in the one-piece type opening history band-equipped cap structure described above in (5), (6) it is preferable that the second breaking portion formed in the band is a bridge formed intermittently along the width direction, and that the first rib also serves as the bridge in the second breaking portion.

[0014] Furthermore, in the one-piece type cap structure with opening history band described above in (5), (7) it is preferable that a second rib is formed on the outer peripheral surface of the band that lifts and supports the TE band portion above the top plate portion, the second rib extending parallel to the width direction of the band so as to intersect with the first rib.

[0015] In addition, in the one-piece type opening history band-equipped cap structure described above in (4), (8) it is preferable that the cap portion has a cap groove formed below the top plate portion capable of accommodating the band body that suspends and supports the TE band portion.

[0016] Furthermore, in the one-piece type cap structure with opening history band described in any of (1) to (8) above, (9) it is preferable that a female thread is formed on the inner surface of the tubular portion, and a male thread that can be screwed into the female thread is formed on the outer surface of the sealing tube.

[0017] Furthermore, in order to solve the above-mentioned problems, a method for setting a one-piece type cap structure with an opening history band in one form of the present invention is a method for setting a one-piece type cap structure with an opening history band as described in claim 1 to a container body for storing contents, and is characterized in that it includes a step of pressing at least the top plate portion of the top lid portion toward the opening of the container mouth portion to fit the sealing tube of the top lid portion into the tubular portion of the container mouth portion, and a step of lowering the TE band portion toward the top plate portion after the fitting, thereby inverting the band body and engaging the TE band portion connected to the band body with a cover portion formed on the outer peripheral surface of the tubular portion. Effect of the Invention

[0018] According to the present invention, the cap including the TE band and the container mouth can be produced in one piece, which improves the visibility of the opening history while simplifying the production line and reducing costs. [Brief description of the drawings]

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] An embodiment for implementing the present invention will be described. For convenience of explanation, the X-direction, Y-direction, and Z-direction are appropriately defined in the following description, but it goes without saying that this does not restrict the scope of the present invention. For matters other than the characteristic features of the present invention described in detail below, for example, the configuration of the spout disclosed in the above-mentioned patent documents or the structure of other known caps and container mouths (spouts) may be appropriately referred to for implementation.

[0021] [One-piece cap structure with opening history band] The one-piece type cap structure with a band having a history of opening 100 can be used, for example, as a spout for pouring out the contents of a container body. As the container body, various known forms such as a paper pack or a resin pouch may be used as long as the container mouth part 10 described later can be fixed.

[0022] 1 to 5 show a one-piece type cap structure with an opening history band 100. More specifically, the one-piece type cap structure with an opening history band 100 of this embodiment is configured to include a container mouth portion 10, an upper lid portion 20, a band 30, and a TE band portion 40 as a tamper-evident band.

[0023] Such a one-piece type cap structure with an opening history band 100 can be injection molded with a known resin material, for example. Examples of resin materials suitable for the one-piece type cap structure with an opening history band 100 include known synthetic resins such as low-density PE (polyethylene), high-density PE, PP (polypropylene), or a mixed resin of PE and PP.

[0024] <Container mouth> The container mouth 10 is configured to have a function of pouring out liquid or solid contents, such as food, drink, or medicine, from a container. The container mouth 10 can be exemplified by a spout. Note that various known methods, such as adhesion or welding, may be used to fix the container mouth 10 to the container body.

[0025] More specifically, the container mouth 10 is fixed to the above-mentioned container body. As shown in Figures 3 and 4, the container mouth 10 of this embodiment is composed of a cylindrical portion 11, a cap portion 12, a female thread 13 formed on the inner wall of the cylindrical portion 11, and a flange portion 14 that expands radially outward in a circular plate shape from the lower end of the cylindrical portion 11.

[0026] The tubular portion 11 is a tubular (e.g., cylindrical) portion from which the contents are poured out. As shown in Fig. 2 and other figures, the tubular portion 11 of this embodiment is, for example, a cylinder of the same diameter above a cap portion 12 described later, and is tapered toward a flange portion 14 below the cap portion 12. As described later, a plurality of first breakable portions 23 described later are connected to the upper ends of the inner surfaces of the tubular portion 11.

[0027] The cover portion 12 is provided on the outer peripheral surface of the cylindrical portion 11. The cover portion 12 is configured to be engageable with the TE band portion 40 described later. More specifically, the cover portion 12 of this embodiment is provided with a plurality of cover grooves 12g arranged discontinuously in the circumferential direction. The cover grooves 12g have a function of accommodating a band 30 that suspends and supports the TE band portion 40 below the top plate portion 21 described later. As shown in the figure, it is preferable that the cover grooves 12g of this embodiment are arranged discontinuously in the circumferential direction in a plurality of grooves corresponding to at least two of the plurality of bands 30 described later.

[0028] The female thread 13 is formed on the inner peripheral surface of the cylindrical portion 11. The female thread 13 can be screwed into a male thread 24, which will be described later, and in this embodiment, a known three-thread thread is applied. The number of threads of the female thread 13 is not limited to the above-mentioned three, and may be other numbers.

[0029] The flange portion 14 is positioned at the lower end of the cylindrical portion 11 and is configured to be fixable to the container body. As an example, the container body and the flange portion 14 may be fixed or welded together using a known adhesive.

[0030] <Upper cover> As can be seen from Figures 1 to 3, the top cover part 20 is configured to include at least a top plate part 21 and a sealing tube 22. The top cover part 20 also includes a first breakable part 23 at the lower end of the sealing tube 22. The top cover part 20 is connected via the breakable first breakable part 23 so that the lower end of the sealing tube 22 is integral with the inner upper end of the cylindrical part 11 at the container mouth 10.

[0031] The top plate portion 21 has the function of blocking the pouring outlet of the container mouth portion 10, and the above-mentioned sealing tube 22 is erected on its underside, while the second end portion 35 of the band body 30 described later is connected to the peripheral edge of the top plate portion 21.

[0032] As one example, top plate portion 21 may have a non-circular outer shape in which the portion to which band body 30 described later is connected is substantially linear and each corner is curved. The outer shape of top plate portion 21 is not limited to the outer shape shown in the drawings, and may be, for example, a shape that matches the outer shape of tubular portion 11 (for example, a disk if tubular portion 11 is cylindrical).

[0033] 2 and 4, the seal tube 22 is configured to descend in the axial direction (Z direction) from the top plate portion 21. As can be seen from the figures, a male thread 24 capable of screwing into the female thread 13 is formed on the outer circumferential surface of the seal tube 22. There are no particular limitations on the male thread 24 as long as it can be screwed into the female thread 13, and various known screw structures can be used.

[0034] As shown in Figure 2, an inner ring 25 is provided on the outer peripheral surface of the sealing tube 22 between the top plate portion 21 and the male thread 24 so as to protrude radially outward, and is capable of engaging with the inner peripheral surface of the above-mentioned tubular portion 11 to seal the contents within the container.

[0035] As can be seen from Fig. 4 and other figures, it is preferable that the outer diameter D1 of the inner ring 25 is larger than the outermost diameter D2 of the first rupture portion 23 described below. This makes it possible to ensure sealing via the inner ring 25 after the container mouth 10 is closed with the upper lid 20.

[0036] The first breakage portion 23 is configured to extend radially outward from the lower end of the sealing tube 22 and connect to the upper end of the inner surface of the cylindrical portion 11 at the container mouth 10. That is, in this embodiment, the inner diameter of the cylindrical portion 11 is set to be larger than the outer diameter of the sealing tube 22, and the sealing tube 22 can be inserted into the cylindrical portion 11. The first breakage portion 23 in this embodiment is not thin-walled but has a bridge structure. Therefore, the first breakage portion 23 as a bridge may be provided intermittently in the circumferential direction (around the central axis θz) so as to bridge between the upper end of the inner surface of the cylindrical portion 11 and the outer edge of the lower end of the sealing tube 22.

[0037] As can be seen from Figures 2 and 3, three first rupture portions 23 as bridges are provided at equal intervals (for example, 120° intervals) along the circumferential direction at the lower end of the sealing tube 22, but the number of first rupture portions 23 may be other than three. Moreover, the first breaking portion 23 only needs to have a thickness and a radial length that enable it to be broken when the container is stopped up, as described below. It is preferable that such a thickness and radial length be determined in advance by experiment or simulation depending on the force required when the container is stopped up and the specifications of the container. Furthermore, it is preferable that the first rupture portion 23 remain on the lower end of the outer surface of the sealing tube 22 after the stoppering from the viewpoint of pouring property and sealing property.

[0038] In this embodiment, the container mouth 10 and the top lid 20 are integrally connected at the bottom end of the sealing tube 22 to the top end of the tubular part 11 via the breakable first breakable part 23 (bridge). The number of the first breakable parts 23 and the number of threads of the male thread 24 are preferably equal to each other. As an example, since the number of the first breakable parts 23 in this embodiment is "3", the male thread 24 in the top lid 20 is preferably configured as a three-thread thread, and further, as shown in FIG. 10, the bridge constituting the first breakable part 23 is preferably disposed on the track of the lower end of the thread of the male thread 24 in the top lid 20. This allows the first breakable part 23 to function as an extension part (part of the thread) of the male thread 24 when the plug is opened or closed by the screw.

[0039] In this case, it is further preferable that the first breaking portion 23 extends in the circumferential direction (θz around the central axis) at an angle with respect to the horizontal plane HP so as to be parallel to the lead angle α of the screw that forms the male thread 24. This allows the first breaking portion 23 to function as part of the screw arranged on an extension line of the male thread 24, thereby achieving smooth opening and closing operations.

[0040] <Belt body and TE band part> The band 30 is configured to have the function of connecting the top cover portion 20 and the TE band portion 40. The band 30 is a band-shaped member including a first end portion 34 connected to the TE band portion 40 and a second end portion 35 connected to the top plate portion 21 of the top cover portion 20. More specifically, the band 30 of this embodiment can be connected to the top plate 21 by extending upward (upward in the Z direction on the paper) from the top plate 21 of the upper lid 20 as shown in Figures 1 to 3. Also, in this embodiment, as described above, it is preferable that the second end 35 of the band 30 is connected to a substantially linear portion of the outer edge of the top plate 21 (a portion having a relatively large radius of curvature around the top plate 21). This reduces the resistance of the band 30 due to its own elasticity when it is set, as will be described later, and the band 30 can be easily turned over, making it a form that is advantageous in terms of turning over.

[0041] As can be seen from these figures, the band 30 of this embodiment is flexible in order to attach the TE band portion 40 to the container mouth portion 10. Moreover, a plurality of bands 30 of this embodiment (four in this example) are intermittently arranged along the circumferential direction on the peripheral edge of the top plate portion 21 of the upper lid portion 20.

[0042] 2, the strip 30 of this embodiment has second breaking portions 31 formed along the width direction (short side direction of the strip) that can be broken when initially opened. Such second breaking portions 31 are preferably bridges formed intermittently along the width direction.

[0043] 1 and 2, it is preferable that a first rib 32 extending along a direction perpendicular to the width direction (long side direction of the band) is formed on the inner peripheral surface of the band 30 that lifts and supports the TE band portion 40 above the top plate portion 21. This makes it possible to increase the strength required for the band 30 while maintaining the flexibility described above.

[0044] As can be seen from the figure, in this embodiment, at least a part of the first rib 32 can be the second breaking portion 31. That is, the first rib 32 can also function as a bridge in the second breaking portion 31. This makes it possible to ensure breakability via the breaking portion while maintaining the necessary strength for the band 30.

[0045] 1 in particular, in the band 30 of this embodiment, it is preferable that a second rib 33 is formed on the outer peripheral surface of the band 30 that lifts and supports the TE band part 40 above the top plate part 21 of the upper cover part 20, the second rib 33 extending parallel to the width direction (short side direction) of the band 30 so as to intersect with the first rib 32. This makes it possible to fold the band 30 according to specifications without reverse bending, using the second rib 33 as a base point, when the TE band part 40 is moved below the turnip part 12 during setting, which will be described later.

[0046] The TE band portion 40 is connected to the band 30. More specifically, the TE band portion 40 is connected to each of the first ends 34 of the multiple bands 30. As a result, the TE band portion 40 of this embodiment is integrally connected to the top plate portion 21 via the band 30 that extends in the axial direction and connects to the top plate portion 21. Furthermore, the TE band portion 40 is housed in the cap groove 12g when it is set in the container body, whereby the engagement between the TE band portion 40 and the cap portion 12 is completed.

[0047] <How to set the one-piece cap structure with the opening history band on the container body> Next, a setting method using the one-piece type cap structure with opening history band 100 in this embodiment will be described with reference to Fig. 6. As an example, the following shows an initial sealing process (setting process) in which the spout-type one-piece type cap structure with opening history band 100 is attached to the above-mentioned container body, and then the top lid part 20 is pressed down and the TE band part 40 is set under the cap part 12.

[0048] First, as a preparation step, the one-piece type cap structure 100 with opening history band as illustrated in Fig. 1 is attached to a container body storing contents such as a beverage. At this time, the inside of the container is in communication with the atmosphere through the gap between adjacent first breakable portions 23.

[0049] After the above-mentioned preparation process, as shown in Figure 6(a), at least the top plate portion 21 of the top lid portion 20 is pressed down toward the tubular portion 11 of the container mouth portion 10, thereby fitting the sealing tube 22 of the top lid portion 20 into the tubular portion 11 of the container mouth portion 10 (top lid plugging process).

[0050] More specifically, in this top cap plugging step, the first breaking portion 23 is first broken by the above-mentioned pressing action. As described above, the first breaking portion 23 after breaking remains at the lower end of the outer surface of the sealing tube 22. Next, the top plate portion 21 is pressed down as it is, so that the sealing tube 22 is fitted into the inside of the tubular portion 11. At this time, the male thread 24 formed on the outer peripheral surface of the sealing tube 22 overcomes the female thread 13 formed on the inner peripheral wall of the tubular portion 11 during the fitting process described above. Through this top cap plugging step, the female thread 13 and the male thread 24 are screwed together, and the sealing tube 22 is inserted into the tubular portion 11, as illustrated in FIG. 7.

[0051] After the above-mentioned fitting in the top lid plugging process, as shown in Figure 6 (b), the TE band portion 40 located above the top plate portion 21 is lowered toward the top plate portion 21, thereby inverting the band 30 and engaging the TE band portion 40 connected to the band 30 with the cap portion 12 formed on the outer peripheral surface of the tubular portion 11 (band engagement process).

[0052] More specifically, in this band engagement step, the band 30 is smoothly folded with the second rib 33 as the base point by the above-mentioned lowering operation. At this time, the cap groove 12g is positioned below the band 30 as shown in Figures 1 and 2, and the folded band 30 engages with the cap groove 12g and the TE band portion 40 is housed below the cap portion 12 (see Figure 6(c)). Through this band engagement step, the initial sealing process is completed and the contents stored in the container body are sealed by the one-piece type cap structure with opening history band 100, as shown in Figures 8 and 9. At this time, the outer surface of the inner ring 25 is in close contact with the upper inner surface of the cylindrical portion 11 over the entire circumference.

[0053] When pouring the contents for the first time after the above-mentioned initial sealing process (initial opening), the user can perform the opening operation by pinching the top lid part 20 and turning it in the opening direction (e.g., counterclockwise) as shown in Fig. 6(d). That is, when the top lid part 20 is turned during initial opening, the second breaking part 31 breaks first with the band 30 engaged with the turnip groove 12g.

[0054] By continuing to rotate the top cover portion 20 in the opening direction even after the second breaking portion 31 breaks, the male thread 24 rises along the female thread 13. Furthermore, a part of the first breaking portion 23 that broke during the top cover plugging process remains as a bridge piece 23' at the bottom end of the seal tube 22, and since this bridge piece 23' and the first breaking portion 23 are positioned on the trajectory of the bottom end of the thread of the male thread 24, the bridge piece 23' also rises along the female thread 13 in the same manner as the male thread 24.

[0055] In this manner, the one-piece type cap structure 100 with an opening history band of this embodiment has a bridge piece 23' formed by the first breaking portion 23 breaking at the time of initial sealing at the lower end of the sealing tube 22. As can be seen from Figures 6(d) and 10, this bridge piece 23' can also be smoothly rolled up without resistance along the female thread 13 following the male thread 24 when opening the cap.

[0056] On the other hand, when resealing the container mouth 10 using the top lid portion 20, the male thread 24 is wound and tightened along the female thread 13, followed by the bridge piece 23', in the reverse order to the uncapping operation described above.

[0057] At this time, one of the bands 30' separated at the second breaking portion 31 remains on the top plate 21 of the top cover 20, so that, for example, a user can use the first rib 32 on the outer surface of the one of the bands 30' as a slip-proof device to perform opening and closing operations. Also, after the initial opening, the TE band 40 remains under the cap 12, so that the opening history can be more clearly seen than in conventional cap-integrated spouts.

[0058] According to the one-piece type cap structure 100 with opening history band and the setting method using this cap structure described above, it is possible to significantly improve the visibility of the opening history while significantly reducing costs.

[0059] Although the preferred embodiment of the present invention has been described in detail above with reference to the accompanying drawings, the present invention is not limited to such an example. It is clear that a person having ordinary knowledge in the technical field to which the present invention pertains can conceive of various modified or altered examples within the scope of the technical ideas described in the claims, and it is understood that these also naturally belong to the technical scope of the present invention. [Industrial Applicability]

[0060] The present invention is suitable for realizing a one-piece cap structure with an opening history band that can be attached to a container body for storing beverages, food, etc. and has significantly improved visibility of the opening history. [Explanation of symbols]
