Description

Technical Field

[0001] The present invention relates to a hinge cap provided with a tamper band for preventing unauthorized use (tampering prevention) and a container with a hinge cap.

Background Art

[0002] As hinge caps provided with a tamper band, there are a tamper-proof hinge cap of Patent Document 1 and a hinge cap of Patent Document 2.

[0003] The tamper-proof hinge cap of Patent Document 1 can be fixed by heat-sealing to the opening of a pouch container made of a flexible film capable of accommodating contents, and includes a spout having a pouring outlet for discharging the contents, and a hinge cap having a tamper band portion for preventing unauthorized opening that is fixed to the spout and removed at the time of opening. The hinge cap includes a main body portion fixed to the pouring outlet of the spout, an upper lid portion having a flange portion connected to the main body portion via a hinge portion, and the tamper band portion connected to the lower end side of the side wall of the upper lid portion via a plurality of thin portions. The tamper band portion is provided with a protrusion extending to the bag body side, and when the protrusion is fitted so as to engage with a locking portion provided on the main body portion and is in a fitted state, the tamper band portion on the lower end side of the flange portion forms the same protruding width as the flange portion, and the tamper band portion is sandwiched between the flange portion and the locking portion, so that the finger space is blocked when not opened. (Claim 1).

[0004] When the upper lid portion of the tamper-proof hinge cap is rotated upward about the hinge portion, unauthorized use is prevented because the protrusion provided on the tamper band portion engages with the locking portion provided on the main body portion. Since the tamper band portion provided with the protrusion is connected to the upper lid portion via a plurality of thin portions arranged in a line, the position setting of the protrusion with respect to the upper lid portion is not strong and is allowed to twist or bend.

[0005] The hinge cap of Patent Document 2 comprises: a cap body having a top plate portion and a cylindrical side wall descending from the periphery of the top plate portion, with a container opening portion fitted and fixed to the inside of the cylindrical side wall; and a top lid having a top plate portion and a skirt portion descending from the periphery of the top plate portion, with the lower end of the skirt portion being connected to the top plate portion or cylindrical side wall of the cap body via a hinge connection portion, and being openable and closable relative to the cap body; wherein when the top lid is closed, the outer peripheral edge of the upper surface of the top plate portion of the cap body and the lower end surface of the skirt portion of the top lid face each other, and an opening flange is provided on the portion of the skirt portion opposite to the hinge connection portion, and the upper surface of the top plate portion of the cap body has a circumferential projection that can engage with the inner surface portion of the skirt portion of the top lid when the top lid is closed, and a strip-shaped cover that covers the outer peripheral tip of the opening flange of the closed top lid is connected to the outer surface of the cylindrical side wall of the cap body via a breakable weakening line or score. The lower surface of the opening flange is located below the upper surface of the top plate, and when the top lid is closed, the lower surface of the opening flange is kept in a non-contact state with the strip-shaped cover, and the inner surface of the strip-shaped cover is provided with a locking projection that engages with the upper surface of the outer peripheral edge of the opening flange of the closed top lid, and a deformation-preventing rib that extends axially so as not to come into contact with the lower surface of the opening flange of the closed top lid, and the circumferential region on the inner surface of the skirt portion of the top lid where the opening flange is formed is not engaged with the circumferential projection of the cap body when the top lid is closed (Claim 1).

[0006] Furthermore, the hinge cap of Patent Document 2 states that, "As is clear from Figures 1 and 2, the above-mentioned strip-shaped cover 50 has a locking projection 53 on the inner surface of its upper portion, and this locking projection 53 engages with the upper surface of the outer peripheral edge of the tip of the opening flange 40 of the closed top lid 3. That is, the lower surface 40a (flat projection 41) of the opening flange 40 of the closed top lid 3 is completely isolated from the outside by the strip-shaped cover 50, and its outer peripheral edge is covered and engaged by the locking projection 53 provided on the inner surface of the strip-shaped cover 50, so that the top lid 3 cannot be opened unless the strip-shaped cover 50 is peeled off from the cylindrical side wall 7 by breaking the weakening line or score 51, and such a strip-shaped cover "The structure is such that the top lid 3 is given tamper-evident properties (TE properties) by 50" (paragraph 0030). [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Publication No. 2022-120424 [Patent Document 2] Japanese Patent Publication No. 2011-201586 [Overview of the project] [Problems that the invention aims to solve]

[0008] In conventional hinge caps equipped with a tamper band, the front part of the top cover rotates upward in an arc around the hinge. However, when the tamper band is attached, it is necessary to ensure engagement between the projection and the locking part. However, because the connection conditions of the tamper band itself are weak, it is difficult to ensure engagement.

[0009] In other words, in the tamper-proof hinge cap of Patent Document 1, since the projection is provided on the tamper band portion, the projection may move in or out of the way relative to the top lid portion due to the softness of the tamper band portion, which may reduce the engagement with the locking portion.

[0010] Furthermore, in the hinge cap of Patent Document 2, the lower end surface of the skirt portion of the upper lid passes through the hinge connection portion, and an opening flange is provided near the lower end surface of the front portion of the skirt portion. When the upper lid rotates upward around the hinge connection portion, the opening flange moves in a direction away from the locking projection of the strip-shaped cover (inward in the diameter of the cap body), which reduces engagement with the locking projection.

[0011] Furthermore, in both conventional technologies, the lower end surface of the front of the lid is located on a straight line passing through the hinge at the rear, making it difficult to expose the spout cylinder below the height of the hinge even when the lid is opened.

[0012] The present invention aims to provide a hinge cap and a container with a hinge cap that can solve the problems of the prior art.

[0013] The present invention aims to provide a hinged cap that ensures a firm engagement between the engaging projection of the top lid and the engaging portion of the tamper band when unopened, and allows the top lid to be opened to expose the spout cylinder when opened.

[0014] The present invention aims to provide a container with a hinged cap, which is attached to the spout and securely engages the engaging projection of the top lid with the engaging portion of the tamper band when unopened, and allows the top lid to be opened to expose the spout cylinder when opened. [Means for solving the problem]

[0015] The specific means for the hinge cap to solve the problem in the present invention is: A cap body A having a spout cylinder portion 3 with an open top end, an outer body cylinder 4 surrounding the outside of the spout cylinder portion 3, and a mounting portion 5 located at the bottom of the spout cylinder portion 3 and the outer body cylinder 4 and attached to the opening of the container, The upper lid B has an inner stopper cylinder 6 that fits onto the spout cylinder 3 from above, and a lid peripheral wall 7 that surrounds the outside of the inner stopper cylinder 6 and whose lower edge can abut against the upper edge of the main body outer cylinder 4, A hinge C connects the main cap body A and the upper lid B at their rear ends, The engaging projection D provided on the front lower part of the lid peripheral wall portion 7 of the upper lid B, The outer cylinder 4 of the main body part A of the cap body part 、 Cuttable Na The engagement projection D is provided via bridge E. and A hinge cap 1 comprising a tamper band portion F having an engageable engagement portion 8, The upper edge of the main body outer cylinder 4 and the lower edge of the upper lid B come into contact with each other, forming a joint line G that passes through the hinge portion C. At the rear of the main body outer cylinder 4, this becomes a rear joint line Gb that passes through the hinge portion C, and at the front of the main body outer cylinder 4, this becomes a front joint line Gf that is one step lower than the rear joint line Gb. The left and right sides of the main body outer cylinder 4 are as described above. The front end of the rear alignment line Gb and the rear end of the front alignment line Gf are separated by a step transition line Gm, and the lower part of the front of the upper lid B is located in front of the spout cylinder 3 and near the front alignment line Gf at its lower edge. Low position The engaging projection D is positioned there, The upper part of the spout cylinder portion 3 protrudes above the rear joint line Gb, and the inner circumferential surface 11 of this upper part has an upper flared portion 11a at the upper end, a lower fitting portion 11b, and an outer sealing portion 11c between the upper flared portion 11a and the fitting portion 11b. The outer circumferential surface 12 of the inner stopper cylinder portion 6 has a fitting portion 12b that fits detachably into the fitting portion 11b, and an inner sealing portion 12c that is in contact with the outer sealing portion 11c.

[0016] Furthermore, a specific means for a container with a hinge cap to solve the problems in the present invention is the hinge The J-Cap 1 is attached to the spout S located on the top of the pouch P. [Effects of the Invention]

[0017] According to the hinge cap of the present invention, when unopened, the engaging projection D of the upper lid B and the engaging portion 8 of the tamper band F can be firmly engaged, and when opened, the upper lid B can be opened to expose the spout cylinder 3, making it easy to pour. Furthermore, the fitting function and sealing function of the spout cylinder 3 and the inner stopper cylinder 6 can be ensured and maintained.

[0018] Moreover, according to the container with a hinge cap of the present invention, it is possible to provide a container with a hinge cap that prevents unauthorized use and is easy to use.

Modes for Carrying Out the Invention

[0020] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0021] In FIGS. 1 to 10, the hinge cap 1 has a cap body part A and an upper lid body B connected by a hinge part C at the rear, and these are integrally molded of synthetic resin. In a state where the upper lid body B is fitted to the cap body part A, it is fitted and mounted to the mouth part Sa of the spout S provided on the container 2.

[0022] In Figures 1 to 9, the cap body A has a spout cylinder 3 with a trumpet-shaped opening at its upper end, an outer body cylinder 4 surrounding the outside of the spout cylinder 3, and a mounting portion 5 located below the spout cylinder 3 and the outer body cylinder 4, which is fitted onto the spout S.

[0023] A hinge portion C is formed at the rear upper part of the main body outer cylinder 4, connecting it to the rear of the top cover B, and a tamper band portion F for preventing misuse is connected via a bridge E from the front to the left and right sides of the main body outer cylinder 4.

[0024] The upper lid B has an inner stopper cylinder 6 that fits from above onto the spout cylinder 3 of the cap body A so as to protrude downward from the circular ceiling portion Be, and a lid peripheral wall portion 7 that surrounds the outside of the inner stopper cylinder 6 and whose lower edge can abut against the upper edge of the main body outer cylinder 4.

[0025] A hinge portion C is formed at the rear of the lid peripheral wall portion 7, a finger-grip flange portion 15 is formed to protrude outward at the extension of the ceiling portion Be at the front upper part of the lid peripheral wall portion 7, and an engagement projection D is formed to protrude outward at the front lower part of the lid peripheral wall portion 7.

[0026] The tamper band portion F has a circular arc shape in plan view, extending from the front of the upper lid B to the lower part of the left and right sides, and is provided on the main body outer cylinder 4 via a plurality of severable (weakened) bridges E, with a engageable portion 8 formed at its front, which can engage with the engaging projection D of the upper lid B.

[0027] The upper edge of the main body outer cylinder 4 and the lower edge of the upper lid B can come into contact when fitted together, and this contact forms a alignment line G passing through the hinge portion C.

[0028] This alignment line G becomes a rear alignment line Gb passing through the hinge C at the rear of the main outer cylinder 4 (and top cover B), and a front alignment line Gf which is one step lower than the rear alignment line Gb at the front of the main outer cylinder 4 (and top cover B). Furthermore, on the left and right sides of the main outer cylinder 4 (and top cover B), the front end of the rear alignment line Gb and the rear end of the front alignment line Gf are connected by a step transition line Gm.

[0029] The aforementioned step transition line Gm is inclined downward from the front end of the rear connecting line Gb to the rear end of the front connecting line Gf.

[0030] The tamper band portion F overlaps the front and lower left and right sides of the upper lid B, and the lower edge of the front portion is close to the front line Gf, extending from the front to the left and right sides of the main body outer cylinder 4. Furthermore, this connection is linked to the front bridge Ef near the front line Gf and the lower lateral bridge Ew1.

[0031] Furthermore, the left and right sides of the tamper band section F intersect with the step transition line Gm at the side of the main body outer cylinder 4, and are connected to the upper lateral bridge Ew2 near this step transition line Gm. The tamper band section F has removable knob sections Fa formed at both ends.

[0032] The aforementioned lower lateral bridge Ew1 is located near the rear end of the front alignment line Gf and also near the lower end of the step transition line Gm, and serves to connect the lower edge of the tamper band section F, from the front to the left and right sides, to the main body outer cylinder 4.

[0033] If the only requirement is to connect the lower edge of the tamper band portion F to the main body outer cylinder 4, then the front bridge Ef and the lower lateral bridge Ew1 alone would suffice, and the conventional technology also uses this straight-line arrangement. However, with only the front bridge Ef and the lower lateral bridge Ew1, deformation (such as twisting or bending) in the direction that the upper edge of the tamper band portion F moves away from the main body outer cylinder 4 is permitted.

[0034] By positioning the upper lateral bridge Ew2 at an intermediate height on the step transition line Gm, the left and right sides of the tamper band section F are connected to the main body outer cylinder 4 by two lateral bridges Ew1 and Ew2, respectively. This prevents deformation of the upper edge of the tamper band section F away from the main body outer cylinder 4, making it difficult for twisting or slippage to occur, and allowing it to be positioned and maintained in an appropriate posture to prevent misuse.

[0035] In Figures 1 and 2, the front alignment line Gf is positioned below the rear alignment line Gb by the height of the step transition line Gm. Therefore, the front of the main body outer cylinder 4 does not surround the spout cylinder 3 over approximately half its circumference. Instead, the front of the top cover B closes the front of the spout cylinder 3. Consequently, when the top cover B is opened upwards, the front of the spout cylinder 3 can be largely exposed over approximately half its circumference.

[0036] The large exposure of the front of the spout section 3 allows the spout section 3 to be brought close to the mouth of the measuring cup when pouring liquid from the spout section 3 into another container such as a measuring cup. In other words, when opening the container, the top lid B is opened to expose the spout section 3 to its full extent, allowing it to be brought close to the mouth of the measuring cup, thus making pouring easier.

[0037] Because the front alignment line Gf is located at a low position, the engagement projection D on the front of the upper cover B can also be positioned at a low position near the front alignment line Gf, and the engagement portion 8 can be formed as a recess cut out from the lower edge of the tamper band portion F.

[0038] The engaging projection D is a triangular projection with a flat upper surface, and the upper surface of the recess of the engaging part 8 can contact and engage with the upper surface of the engaging projection D. This engagement restricts the lifting operation of the front part of the upper lid B relative to the outer cylinder 4 of the main body, resulting in an unopened state.

[0039] The engagement point between the engaging projection D and the engaging upper part 8 is at the lower part of the front surface of the upper cover B, and as shown in Figure 2, it lies on a connecting line h that slopes forward and downward from the hinge part C with respect to the rear alignment line Gb that passes through the hinge part C.

[0040] When the lid of the top cover B is opened in the aforementioned unopened state, the front part of the top cover B rises around the hinge C. However, if the engaging projection D on the lower front of the top cover B is below the rear alignment line Gb, the rise will move radially outward from the center of the main body outer cylinder 4 to the height of the rear alignment line Gb (the circular arc trajectory j in Figure 2).

[0041] In this case, if the tamper band portion F is not detached, the front of the top lid B pushes out the front of the tamper band portion F, and at the same time, the engaging projection D follows up to engage with the engaging portion 8. This ensures engagement between the engaging projection D and the engaging portion 8, preventing the top lid B from opening. In other words, the tamper-tamper prevention function provided by the tamper band portion F is guaranteed.

[0042] When the tamper band F is detached by the front bridge Ef, the lower lateral bridge Ew1, and the upper lateral bridge Ew2 for proper use, the engaging upper part 8 ceases to exist, thus relieving the restriction on the engaging projection D and resulting in an open state with the anti-tampering (anti-falsification) mechanism released.

[0043] In Figures 1, 2, 6, and 8, the upper part of the spout cylinder portion 3 protrudes above the rear joint line Gb, and the inner circumferential surface 11 of this upper part has an upper flared portion 11a at the upper end, a lower fitting portion 11b, and an outer sealing portion 11c between the upper flared portion 11a and the fitting portion 11b.

[0044] On the other hand, the outer circumferential surface 12 of the inner stopper cylinder portion 6 is formed with a fitting portion 12b that fits detachably into the fitting portion 11b, and an inner seal portion 12c that is in contact with the outer seal portion 11c.

[0045] The fitting portion 11b and the outer sealing portion 11c, and the fitting portion 12b and the inner sealing portion 12c are located at approximately the same height as the rear alignment line Gb. The fitting of the fitting portion 11b and the fitting portion 12b restricts unintended opening of the upper cover B, and the fitting contact of the outer sealing portion 11c and the inner sealing portion 12c ensures an internal seal when the upper cover B is closed.

[0046] In Figure 6, the fitting of the mating portion 11b and the inserting portion 12b is shown with their surfaces in close contact, while the fitting contact of the outer seal portion 11c and the inner seal portion 12c is shown with their surfaces overlapping.

[0047] The overlapping state of the surfaces indicates that the thickness of each part is marked as designed. However, when the parts are actually fitted together, each part elastically deforms in the direction of its thickness, resulting in a close fit with no overlap between the surfaces. This creates a more resilient and tightly fitting seal than the fitting of the fitting part 11b and the insertion part 12b.

[0048] While it is possible to perform both the mating and sealing functions in one location, dividing them between two locations allows each function to be performed more efficiently. For example, when the mating part is opened and closed multiple times, it may become damaged and scratched, but the outer sealing part 11c and the inner sealing part 12c remain undamaged, thus maintaining their sealing performance.

[0049] Figure 10 shows the entire container 2 with a hinged cap, in which a spout S is provided at the top of a roughly rectangular pouch P, and the hinged cap 1 is attached to this spout S.

[0050] The pouch P has an upper edge, left and right side edges, and a bottom edge. The corner where one of the left or right side edges intersects with the upper edge is cut out to form a triangular space K and an inclined edge L, and the spout S is positioned on this inclined edge L. The hinge cap 1 attached to the spout S is housed within the triangular space K that corresponds to the shoulder of the pouch P, and is also sized to fit within the triangular space K.

[0051] In Figures 1, 2, and 9, a rotation-preventing mechanism 14 is formed between the inner circumferential surface of the mouth Sa of the spout S and the mounting portion 5 of the cap body A, which determines the circumferential position and prevents rotation.

[0052] The anti-rotation means 14 is arranged at four equally spaced circumferential locations on the mouth Sa of the spout S. Two projections form an elongated groove 21 on the inner circumferential surface of the mouth Sa, and two protrusions form a convex ridge 22 on the mounting portion 5 of the cap body A that is inserted into the elongated groove 21. The mounting portion 5 of the cap body A is fitted axially to the mouth Sa, and the convex ridge 22 fits into the elongated groove 21, thereby achieving circumferential positioning.

[0053] As shown in Figures 7 and 8, the hinged cap 1 is manufactured in an unfolded position with the cap body A and the upper lid B separated by the hinge C, which is the state before the upper lid is fitted. From this state, the upper lid B is rotated to bend the hinge C, and the inner stopper cylinder 6 is fitted onto the spout cylinder 3 from above while the lid peripheral wall 7 is placed over the main body outer cylinder 4. The engaging projection D on the lower front of the upper lid B engages with the engaging portion 8 of the tamper band F, which is provided via the bridge E of the cap body A.

[0054] This results in a hinged cap 1 equipped with a tamper band to prevent misuse, which is then attached to the mouth Sa of the spout S to form the product container 2.

[0055] In the embodiment described above, the hinge cap 1 has a cap body A having a spout cylinder portion 3 with an open upper end, a main body outer cylinder 4 surrounding the outside of the spout cylinder portion 3, and a mounting portion 5 located at the lower part of the spout cylinder portion 3 and the main body outer cylinder 4 and attached to the mouth of the container; an upper lid B having an inner stopper cylinder portion 6 that fits onto the spout cylinder portion 3 from above, and a lid peripheral wall portion 7 surrounding the outside of the inner stopper cylinder portion 6, the lower edge of which can abut against the upper edge of the main body outer cylinder 4; and a hinge portion C connecting the rear ends of the cap body A and the upper lid B. A hinge cap 1 comprising an engaging projection D provided on the front lower part of the lid peripheral wall portion 7 of the upper lid body B, and a tamper band portion F provided on the main body outer cylinder 4 of the cap body portion A via a severable bridge E and having a engaging portion 8 that can engage with the engaging projection D, wherein the upper edge of the main body outer cylinder 4 and the lower edge of the upper lid body B come into contact to form a mating line G passing through the hinge portion C, and at the rear of the main body outer cylinder 4, this becomes a rear mating line Gb passing through the hinge portion C, and at the front of the main body outer cylinder 4, one step below the rear mating line Gb The front alignment line Gf is formed, and the front end of the rear alignment line Gb and the rear end of the front alignment line Gf form a step transition line Gm. The lower part of the front of the upper lid B is located in front of the spout cylinder 3, and the engaging projection D is positioned near the front alignment line Gf on its lower edge.

[0056] This configuration ensures a secure engagement between the engaging projection D of the top lid B and the engaging portion 8 of the tamper band F when unopened, and when opened, the top lid B can be opened to expose the spout cylinder 3, making it easy to pour.

[0057] Furthermore, in the above embodiment, the hinge cap 1 has a tamper band portion F whose front portion is connected to a front bridge Ef near the front line Gf at the front of the main body outer cylinder 4, and whose left and right side portions are connected to lateral bridges Ew near the step transition line Gm at the sides of the main body outer cylinder 4, with the lateral bridges Ew being formed at two locations Ew1 and Ew2, one above the other.

[0058] This configuration allows the tamper band portion F to be positioned and held in the correct posture relative to the main body outer cylinder 4, without twisting or bending.

[0059] Furthermore, in the above embodiment, the upper part of the spout cylinder portion 3 of the hinge cap 1 protrudes above the rear joint line Gb, and the inner circumferential surface 11 of this upper part has an upper flared portion 11a at the upper end, a lower fitting portion 11b, and an outer sealing portion 11c between the upper flared portion 11a and the fitting portion 11b, and the outer circumferential surface 12 of the inner stopper cylinder portion 6 has a fitting portion 12b that fits detachably into the fitting portion 11b and an inner sealing portion 12c that is in contact with the outer sealing portion 11c.

[0060] This configuration ensures and maintains the fitting and sealing functions of the spout cylinder 3 and the inner stopper cylinder 6.

[0061] Furthermore, in the embodiment described above, the hinge cap 1 has the step transition line Gm inclined downward from the front end of the rear alignment line Gb to the rear end of the front alignment line Gf.

[0062] This configuration allows the spout cylinder portion 3 to be largely exposed when opened, making it possible to form a larger front portion of the top lid B, and the upper part 8 can be positioned at the front line Gf, thus preventing misuse.

[0063] In the above embodiment, the container has a hinge cap 1 attached to a spout S provided on the top of the pouch P.

[0064] This configuration provides a container with a hinged cap that prevents misuse and is easy to use.

[0065] Furthermore, in the above embodiment, the container has an anti-rotation means 14 formed between the inner circumferential surface of the spout S and the mounting portion 5 of the cap body A, which determines the circumferential position and prevents rotation.

[0066] This configuration allows the hinge cap 1 to be positioned and held in the correct location relative to the spout S of the container.

[0067] Furthermore, in the above embodiment, the container has an upper edge, left and right side edges and a bottom edge, and a triangular space K and an inclined edge L are formed by cutting out the corner where one of the left and right side edges intersects with the upper edge, the spout S is placed on this inclined edge L, and the hinge cap 1 attached to the spout S is housed in the triangular space K.

[0068] This configuration allows the hinge cap 1 to be housed within the triangular space K when the pouch P is roughly rectangular, making the overall design compact.

[0069] It should be noted that the present invention is not limited to the embodiments described above, and the shape, configuration, and combination of the members can also be changed.

[0070] For example, the difference in height between the rear alignment line Gb and the front alignment line Gf may be approximately the same as the vertical width of the tamper band section F, and the step transition line Gm may be approximately parallel to the center line of the hinge cap 1.

[0071] The hinge section C may be a hinge structure using connecting pins, rather than a one-piece molded folding structure.

[0072] The upper cover B has a recess formed on its front upper part, which can be used as a claw-hooking part, or the upper part of the recess can be used as a flange. Furthermore, even without the flange 15, it is possible to release it by pressing the front upper part with a finger. [Explanation of Symbols]
