Description

  The present invention relates to a hinge cap in which a lid body is connected to a cap body attached to a mouth tube portion of a container via a hinge portion so as to be opened and closed.

  It has a cap body fitted to the container body side, a lid body that covers the top surface of the cap body, and a hinge part provided at the rear part of the cap body, and the lid body is connected to be freely opened and closed via the hinge part. In the hinge cap, a configuration has been proposed in which engaging means by concave-convex engagement is provided at the front of the cap body and the lid (for example, Patent Document 1).

  In addition, both sides of the peripheral wall of the lid are configured to be elastically deformable inward, and elastically deformed so that the front part of the peripheral wall protrudes forward during elastic deformation of both sides of the peripheral wall, thereby engaging the lid and the cap body. A configuration has been proposed in which the engaging means to be combined is released (for example, Patent Document 2).

  For example, small food and beverage containers filled with lemon juice and the like, and cosmetic containers filled with cosmetic liquid and the like are often carried in handbags due to their properties. For this reason, it is necessary to prevent the lid from opening against the user's will during carrying.

  However, in the technique described in Patent Document 1, since the protruding finger-hanging part for releasing the engaging means is formed at the position of the front part of the lid, the container moves in the handbag being carried. Then, there is a problem that some external force acts on the finger-hanging part, the lid opens against the user's will, and the content liquid leaks out.

  On the other hand, since the technique described in Patent Document 2 has a configuration that does not have a protruding finger-hanging portion on the outer surface of the lid, the above-described problems can be solved.

  However, when the overall shape of the hinge cap, in which the cap body and the lid are flush with each other, is cylindrical, it is difficult to understand the pressing position for elastic deformation inward. For this reason, there are cases where the user's finger (usually the thumb and forefinger) hangs on the side of the cap body rather than the side of the lid, and the user can see both sides of the lid that are elastically deformed. Even if it is intended to be pressed, an erroneous operation of actually pressing both sides on the cap body side occurs. For this reason, there is a problem that the engaging means cannot be released well and the lid cannot be opened reliably.

  In order to solve the above-described problems in the prior art, the present invention has a hinge cap of a type that does not have a protruding finger-hanging portion on the outer surface of the lid, and releases the engaged state by pressing both sides of the lid. Therefore, it is an object of the present invention to create a hinge cap in which the pressing positions on both sides are clarified so that an erroneous operation at the time of opening the lid is difficult to occur and the engaging means can be easily and reliably released.

Among the means for solving the above-mentioned problems, the main structure of the present invention is that a cap body having a hollow nozzle for pouring the content liquid on the top wall and a pair of inclined surfaces formed at positions on both sides of the nozzle. And having a cylindrical projection with a sliding projection that is slidable along the inclined surface on the inner surface of the peripheral wall that faces the pair of inclined surfaces, and that fits the top wall. A hinge cap comprising: a lid, a hinge part that connects the lid to the cap body so as to be openable and closable; and an engagement means that maintains a state in which the lid fits the cap body,
The surface of the peripheral wall of the cap body and the surface of the peripheral wall of the lid body are formed to be flat and flush with each other, and the boundary between the surface of the peripheral wall of the cap body and the peripheral wall surface of the lid body on both sides of the hinge cap It is said that a step portion is provided in the portion.

  In the main configuration of the present invention, it is possible to reliably specify the pressing positions provided on both sides of the hinge cap mainly from the touch surface and to achieve elastic deformation of the lid.

  According to another aspect of the present invention, in the main invention, the stepped portion is formed by a concave missing portion formed on the surface of both sides of the mounting peripheral wall of the cap body and at the upper end position that is a boundary with the peripheral wall of the lid. It is a thing which added the structure.

  In the above configuration, it is possible to achieve the formation of the step portion corresponding to the dimensional difference in the radial direction between the surface of the peripheral wall on the lid body side and the defective portion formed on the mounting peripheral wall on the cap body side.

  In addition, another configuration of the present invention is the main configuration, in which a stepped portion is a convex ridge formed on the surface of both sides of the peripheral wall of the lid and at the position on the opening end side that is the boundary with the mounting peripheral wall of the cap body. It is what added the structure that it formed with the part.

  In the above configuration, it is possible to achieve the formation of the step portion corresponding to the dimensional difference in the radial direction between the raised portion formed on the peripheral wall on the lid side and the surface of the mounting peripheral wall on the cap body side.

  In another configuration of the present invention, the main configuration is that a stepped portion is formed on the surface of both sides of the mounting peripheral wall of the cap body and at the upper end position that is a boundary between the peripheral wall of the lid body, And a convex raised portion formed on the surface of both sides of the peripheral wall of the body and at the position on the opening end side that is a boundary with the mounting peripheral wall of the cap body.

  In the above-described configuration, it is possible to achieve the formation of the stepped portion according to the dimensional difference in the radial direction between the raised portion formed on the peripheral wall on the lid side and the defective portion formed on the mounting peripheral wall on the cap body side.

  Moreover, the other structure of this invention adds the structure that a defect | deletion part and a protruding part combine and form one pattern to said structure.

  In the above configuration, it is possible to achieve the pressing positions on both sides mainly from a visual aspect.

  According to another configuration of the present invention, in any one of the configurations described above, the engagement means is provided in an engagement recess provided in one of the peripheral step portion of the cap body and the inner surface of the peripheral wall of the lid, and in the other. In addition to the above, it is constituted by a combination with the engaging convex portion.

  In the above configuration, it is possible to achieve the maintenance of the closed state in which the lid body fits the upper surface of the cap body.

  Since the present invention has the above-described configuration, the following effects can be obtained.

  In the main configuration of the present invention, since the outer surface of the lid does not have a protruding finger-hanging portion, the lid does not open against the user's will during carrying. Further, the stepped portion (pressing position) can be specified by the feeling when tracing both sides with a finger. Accordingly, it is possible to prevent an erroneous operation and appropriately elastically deform the lid body so that the hinge cap can be reliably opened.

  In addition to the main configuration of the present invention, the step portion is formed by a concave deficient portion formed on the surface of both sides of the mounting peripheral wall of the cap body and at the upper end position that is the boundary with the peripheral wall of the lid. In this case, both sides (pressing position) can be specified by tracing the missing part formed on the cap body with your fingers, so that the lid can be elastically deformed and the hinge cap can be securely secured The lid can be opened.

  Further, in the main configuration of the present invention, the stepped portion is formed by a convex ridge formed on the surface of both sides of the peripheral wall of the lid body and at the position on the opening end side serving as a boundary with the mounting peripheral wall of the cap body. In addition to the above structure, both sides (pressing positions) can be specified by tracing the raised part formed on the peripheral wall on the lid side with fingers, so that the operation of the lid can be prevented properly. By elastically deforming, the hinge cap can be reliably opened.

  Further, in the main configuration of the present invention, a stepped portion is formed on the surface of both sides of the mounting peripheral wall of the cap body and at the upper end position which is the boundary between the peripheral wall of the lid and both sides of the peripheral wall of the lid. In addition to the configuration of the convex bulge formed at the position of the opening end side that is the boundary between the surface of the cap body and the mounting peripheral wall of the cap body, the defective portion formed on the cap body side Both sides (pressing position) can be specified by tracing both the ridge and the raised part formed on the lid side with a finger, so that the lid body can be elastically deformed properly and the hinge cap can be securely secured. The lid can be opened.

  In addition to the above configuration, in addition to the configuration in which the defect portion and the raised portion are combined to form a single pattern, the stepped portion that is the pressing position on both sides is specified from the visual aspect. Therefore, it is possible to more reliably prevent the occurrence of an erroneous operation, appropriately elastically deform the lid body, and reliably open the hinge cap.

  In any one of the above configurations, the engagement means is a combination of an engagement recess provided on one of the peripheral step portion of the cap body and the inner surface of the peripheral wall of the lid, and an engagement protrusion provided on the other. With the addition of that, the lid can maintain the closed state where the top surface of the cap body is fitted, thus preventing the occurrence of malfunctions that result in the opened state against the user's intention. can do.

  In the following description, the position where the hinge part 30 is formed is the rear part of the hinge cap, the position where the engaging recess 15 is formed is the front part of the hinge cap, and the pair of missing parts 11a and 11a are formed. This position is the both sides of the hinge cap.

  The hinge cap A has a cap body 10, a lid 20 and a hinge part 30 which are integrally formed by injection molding a synthetic resin material. The cap body 10 and the lid 20 are opened and closed via the hinge part 30. It is the structure connected freely. As shown in FIG. 1, such a hinge cap A is used in a state where the cap body 10 is assembled to the mouth tube portion 2 of the container 1.

  The cap body 10 is a cylindrical member having a cylindrical mounting peripheral wall 11 and a top wall 12. The cap main body 10 protrudes inwardly from the inner peripheral surface 11 A of the mounting peripheral wall 11 and the mouth tube portion 2 of the container 1. A mounting portion 13 is provided around the mounting portion. In addition, as shown in FIG. 4, the attaching part 13 is partitioned off by the vertical groove 13a formed with the fixed center angle in the circumferential direction.

  As shown in FIGS. 1 to 3, the mounting peripheral wall 11 is partially formed in a thin concave shape at the upper end position that is the boundary between the surface of both sides of the mounting peripheral wall 11 and the peripheral wall 21 of the lid 20. A pair of missing portions 11a, 11a is formed. A peripheral step 14 is provided around the edge between the mounting peripheral wall 11 and the top wall 12. Between the circumferential step portion 14 and the front portion of the top wall 12, an engagement recess 15 is formed that can be engaged with an engagement projection 24 formed on the lid 20 side described later.

  A hollow nozzle 16 projecting upward is formed at the center of the top wall 12 on the upper surface side. The nozzle 16 has a cylindrical nozzle base end 16A provided on the lower side and an upper nozzle tip 16B. The diameter is gradually narrowed from the nozzle base end 16A toward the upper nozzle tip 16B. The cross section has a substantially arc shape. An opening 17 is formed inside the nozzle 16. As shown in FIGS. 1 and 6, a pair of inclined surfaces 12 a and 12 a having a tapered shape are formed on both sides of the top wall 12.

  The lid 20 has a cylindrical shape with a cylindrical peripheral wall 21 having the same diameter as the mounting peripheral wall 11 and a top wall portion 22 that covers one end of the peripheral wall 21 (see FIG. 5). A pair of raised portions 21 a and 21 a formed in a thick convex shape are provided on the surface of both sides of the peripheral wall 21 and on the opening end side that is a boundary with the mounting peripheral wall 11 of the cap body 10. Engagement protrusions 24 are annularly provided around the inner wall 21 </ b> A side edge of the peripheral wall 21, and a tip portion of the engagement protrusion 24 can engage with the engagement recess 15 on the cap body 10 side.

  On the back surface 23 of the top wall portion 22, a sealing peripheral wall 25 formed in a cylindrical shape is suspended. The inner diameter of the sealing peripheral wall 25 is formed to be slightly larger than the outer diameter of the nozzle base end 16A. At the distal end of the sealing peripheral wall 25, there is provided a sealing portion 25a that abuts against the outer surface of the nozzle base end 16A to create a close fitting state when the cover is closed.

  As shown in FIGS. 1 and 2, the hinge portion 30 integrally connects the mounting peripheral wall 11 of the cap body 10 and the lid body 20. Specifically, the hinge part 30 includes a central main arm part 31 and a first auxiliary arm part 32 and a second auxiliary arm part 33 on both sides thereof. The main arm portion 31 is formed wide, and the first auxiliary arm portion 32 and the second auxiliary arm portion 33 are formed in a state where the main arm portion 31 is sandwiched between both sides at a predetermined distance from the main arm portion 31. ing. The main arm portion 31, the first auxiliary arm portion 32 and the second auxiliary arm portion 33 are formed integrally with the cap body 10 and the lid body 20. The first auxiliary arm portion 32 and the second auxiliary arm portion 33 are formed to be narrower than the main arm portion 31, and by reinforcing the connection between the cap body 10 and the lid body 20 by the main arm portion 31, the lid The opening / closing operation of the body 20 is stabilized.

  As shown in FIG. 5, when the lid body 20 is rotated around the hinge portion 30, the engagement convex portion 24 on the lid body 20 side and the engagement concave portion 15 on the cap body 10 side can be engaged. it can. Thereby, the lid 20 is set in a closed state in which the top wall 12 having the nozzle 16 of the cap body 10 is fitted. That is, the engagement recess 15 and the engagement protrusion 24 function as the engagement means B that maintains the closed state in which the lid 20 covers the cap body 10. At this time, the sealing peripheral wall 25 extrapolates the nozzle 16, and the nozzle tip 16B is sealed. Further, as shown in FIG. 7, at the positions on both sides, the engaging convex portion 24 that is annularly provided on the inner surface 21 </ b> A of the lid 20 faces the pair of inclined surfaces 12 a and 12 a.

  The mounting peripheral wall 11 of the cap body 10 and the peripheral wall 21 of the lid body 20 are formed with the same diameter, and both surfaces are formed in a flat, flat state with a small step, so that the pressing position is identified. Is difficult. However, in the present invention, the side surface (the mounting peripheral wall 11 and the peripheral wall 21) of the hinge cap A is traced with the abdomen of the finger by forming the defect portion 11a and the raised portion 21a that form the concavities and convexities on both sides. It is possible to clearly identify the positions of the defect portion 11a and the raised portion 21a, that is, the pressing positions on both sides without looking at the side surface.

  As shown in FIG. 3, the planar shape of the defect portion 11 a formed on the surface of the mounting peripheral wall 11 of the cap body 10 is formed in a substantially semicircular shape, and the raised portion 21 a formed on the surface of the peripheral wall 21 of the lid 20. The planar shape is also formed in a substantially semicircular shape. As shown in FIG. 8, when the hinge cap A in the closed state is viewed from the side, the defect portion 11a and the raised portion 21a are combined to form one pattern. . In this Embodiment, the defect | deletion part 11a and the protruding part 21a are the structures which form the leaf pattern of one tree. As described above, according to the present invention, it is possible to visually specify the pressing positions of both side portions constituted by the defective portion 11a and the raised portion 21a, and to improve the design of the hinge cap A. .

  Next, release of the engaging means B will be described. In order to release the engaging means B, as shown in FIG. 9, the pair of raised portions 21a, 21a on the lid body 20 side are simultaneously opened using two fingers F, F (for example, thumb and index finger). This is done by pressing towards the direction. Then, the portions located on both sides of the annular engaging projection 24 function as sliding protrusions 24a and 24a, and slide inward on the pair of inclined surfaces 12a and 12a. Accordingly, both side portions of the peripheral wall 21 of the lid body 20 are elastically deformed in a direction approaching each other, but the front portion of the peripheral wall 21 of the lid body 20 is elastically deformed outward (forward) away from the center portion. Therefore, the engagement means B can be released, that is, the engagement by the engagement convex portion 24 on the lid 20 side and the engagement concave portion 15 on the cap body 10 side can be released.

  At this time, the sliding projections (engagement convex portions) 24a and 24a located on both sides simultaneously climb the slope while sliding on the inclined surfaces 12a and 12a. Therefore, since the lid 20 is moved upward, the hinge cap A can be automatically guided to the open state. In addition, if the press with respect to the both sides of the surrounding wall 21 is cancelled | released, the shape of the hinge cap A elastically deformed will return to the original state before a deformation | transformation.

  Here, the cap body 10 assembled to the container 1 is less likely to be elastically deformed than the lid body 20. For this reason, in the structure which does not have the defect | deletion part 11a and the protruding part 21a, when both sides are pressed together with the two fingers F and F, the belly of the finger F and the mounting peripheral wall 11 of the cap main body 10 When straddling both the peripheral walls 21 of the lid 20, the elastic deformation on the lid 20 side is restricted by the mounting peripheral wall 11 of the cap body 10, and the amount of elastic deformation of the peripheral wall 21 becomes small and the engagement means B is released satisfactorily. It may not be possible.

  However, in the configuration in which the thin-walled concave defect portion 11a is formed in the mounting peripheral wall 11 on the cap body 10 side as in the present invention, and the thick convex protrusion portion 21a of the peripheral wall 21 on the lid body 20 side is formed, the defect A stepped portion C caused by a radial dimension difference Δφ is formed between the portion 11a and the raised portion 21a. Therefore, as shown in FIG. 9, even if the step portion C is pressed together with the belly of the finger F straddling both the defect portion 11a and the bulge portion 21a, at least the surface of the bulge portion 21a remains at the defect portion 11a. The lid 20 can be elastically deformed inward until reaching the surface. For this reason, it becomes possible to ensure the minimum amount of elastic deformation at both side portions, and the engagement means B can be reliably released.

  In order to form the stepped portion C, a dimensional difference Δφ may be provided at the boundary portion between the mounting peripheral wall 11 on the cap body 10 side and the peripheral wall 21 on the lid body 20 side. It is also possible to adopt a configuration in which a pair of missing portions 11a are formed only on both sides of the peripheral wall 11, or a configuration in which a pair of raised portions 21a are formed only on both sides of the peripheral wall 21 on the lid 20 side. However, as shown in the present embodiment, the dimensional difference Δφ of the stepped portion C is increased when the pair of missing portions 11a and the pair of raised portions 21a are formed on both sides of the cap body 10 and the lid body 20, respectively. Since the hinge cap A can be greatly elastically deformed, the engagement means B can be released more reliably, which is preferable.

  As described above, the configuration and the operation effect of the present invention have been described according to the embodiment, but the present invention is not limited to the above embodiment.

  For example, in the above embodiment, as the engaging means B, the configuration in which the engaging convex portion 24 is provided on the lid body 20 side and the engaging concave portion 15 is provided on the cap body 10 side is shown and described. It is not limited to the said embodiment, It is good also as a structure which provided the engagement recessed part in the cover body 20 side, and provided the engagement convex part in the cap main body 10 side.

  Further, in the above embodiment, the configuration in which the tip end portion of one annular engaging convex portion is the engaging convex portion 24 and both side portions are the sliding protrusions 24a and 24a has been described, but the present invention is described above. It is not limited to this form, The structure which formed the engaging convex part 24 of the front-end | tip part and the sliding protrusion 24a of both sides separately may be sufficient.

  INDUSTRIAL APPLICABILITY The present invention can be used in a wider area in the field of hinge caps attached to the mouth tube portion of a container.
