Abstract

<P>PROBLEM TO BE SOLVED: To prevent breakage of a hinge caused by twisting force or the like. <P>SOLUTION: A cap 12 includes a lid 14 of the cap for covering the upper surface of a cap body 13, which is coupled via a pair of thin hinges 15 elastically deformable. A pair of engaging walls 19 slantly facing at a predetermined interval are extended slantly from the direction X of opening/closing the lid 14 of the cap toward the thin hinges 15 on the upper surface of the cap body 13. Engaged walls 20 slantly facing at a predetermined interval are formed toward the thin hinges 15 inside the cap lid 14 to engage with the engaging walls 19 when the cap lid 14 is closed. Thus, torque around the thin hinge 15 located outside the cap lid 14 caused when external force in the lateral direction or the twisting direction is applied to the cap lid 14 is decreased by resistance by the engagement of the wall 19 on the upper surface of the cap body 16 and the wall 20 inside the cap lid 14, thereby also weakening force applied to the hinge 15. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a cap attached to a mouth of a container.

  Conventionally, the mouth of a container filled with liquid or viscous material such as shampoo or whole body cleaning material is made of a soft synthetic resin having a recloseable structure connected to the cap body by an elastically deformable hinge. The cap is worn.

  The hinges provided on such caps are usually thick (thickness) and shape that satisfy conditions such as strength and flexibility, but various proposals have been made to make up for insufficient physical strength. (For example, refer to Patent Document 1).

In the example described in Patent Document 1 shown in FIG. 1, a cap 30 includes a cap body 31 and a lid 32 connected by a pair of hinges 33, and a pair of hinges 33 inside the lid 32 is disposed at a predetermined interval. The wall portion 34 is extended substantially in parallel along the opening / closing direction of the lid 32, and a pair of groove portions 35 are formed on the upper surface of the cap body 31. When the lid 32 is closed, the wall portion 34 is engaged with the groove portion 35. To match. As a result, even if an external force in the lateral direction or twist direction is applied to the lid 32, the force applied to the hinge 33 is also weakened because the resistance is reduced by the engaging portion of the wall portion 34 and the groove portion 35.
JP 2001-206415 A

  However, since the wall portion 34 and the groove portion 35 are installed substantially parallel to the opening / closing direction of the cap, if a strong pressing force is applied to the cap at the time of opening / closing, the hinge portion may be damaged. There is.

  In view of the above facts, an object of the present invention is to provide a cap in which breakage of a hinge caused by a twisting force applied to a lid is improved.

According to the first aspect of the present invention, there is provided a main body portion that is attached to the mouth portion of the container and seals the mouth portion, a spout provided on the upper surface of the main body portion, for pouring the contents of the container, and the spout A lid that covers the upper surface of the main body, a hinge that is provided outside the lid and connects the lid to the main body so as to be opened and closed, and an opening / closing direction of the lid on the upper surface of the main body The cap has an engaging wall provided obliquely with respect to the engaging portion, and an engaged wall that is provided inside the lid portion and engages closely with the engaging wall in a state where the lid portion is closed.

  According to the first aspect of the present invention, the engaging wall at the upper part of the main body engages with the engaged wall inside the lid until the lid for covering the upper surface of the main body together with the spout reaches a certain range of the lid opening angle. To do.

  Therefore, when an external force such as a parallel direction (front-rear direction), an orthogonal direction (lateral direction), or a twist direction is applied to the lid in the opening / closing direction, Since the provided engaged wall generates a resistance force against the external force, it is possible to improve the breakage of the hinge portion caused by a twisting force or an impact force applied to the lid portion. In addition, the rotational moment centered on the hinge located outside the lid of the cap, which is generated when a lateral or twisting external force is applied to the lid of the cap, causes the engagement wall and the lid on the upper surface of the main body. Since it is made small by the resistance force by the engaging portion of the inner engaged wall, the force applied to the hinge portion is also weakened.

  Invention of Claim 2 has a biasing means which urges | biases the said cover part to the said main body part side in the cap of Claim 1, and the said cover part is urged | biased to the said main body part side The engaging wall is engaged with the engaged portion.

  In the invention according to claim 2, since the engaging portion engages with the engaged portion when the lid portion is urged toward the main body portion by the urging means, for example, the lid portion is attached to the main body portion. Even when the cap is configured to be fitted and locked to the cap, when an external force is applied to the unlocked lid portion, the load applied to the hinge portion is reduced by the resistance force at the engaging portion.

  In addition, in the structure in which the lid portion is not fitted and locked to the main body portion but closed only by being urged to the main body portion side by the urging means, similarly, the lid portion is twisted, etc. The force applied to the hinge portion is suppressed by the engaging portion.

  Here, when a large pressing force is directly applied to the cap due to a drop of the container or the like, the lid portion and the main body portion try to deform away from each other, but the engaging walls installed in each of them are engaged with each other. Therefore, a large resistance force is generated against any pulling force in the left-right direction, the front-rear direction, and the twist direction. Therefore, the damage by the container fall etc. of the hinge part which consists of an elastic member can be improved.

  Further, since both the engaging wall and the engaged wall are disposed in the vicinity of the hinge portion and obliquely with respect to the opening / closing direction of the lid portion, smooth engagement is possible without hindering the opening / closing operation of the lid portion.

  According to the cap of the present invention, the breakage of the hinge caused by the twisting force applied to the lid can be improved.

  As shown in FIGS. 2 and 3, a cap 12 according to a preferred embodiment of the present invention is provided at the mouth of a container body 11 containing therein a liquid such as a shampoo or a whole body cleaning material or the contents of a viscous material. By being crowned, the container 10 with the hinge lid is configured together with the container body 11. In addition, the cap 12 includes a main body portion 13 disposed to cover the upper end portion of the container main body 11 including the shoulder portion 11 a and the head portion 11 b (see FIG. 4), and the main body portion 13 of the cap 12 through the thin hinge portion 15. The lid 14 is connected to the periphery so as to be openable and closable.

  In the present embodiment, the body portion 11c of the container body 11 has a substantially quadrangular outer peripheral cross-sectional shape in which the four side surfaces 11d and the four corner portions 11e connecting these side surfaces 11d are continuously curved while being smoothly curved. The cap 12 connected to the body portion 11c also has a substantially rectangular outer peripheral cross-sectional shape in which the four side surfaces 12d and the four corner portions 12e connecting the side surfaces 12d are continuously curved while being smoothly curved. . On the other hand, the lid 14 of the cap 12 is connected to the peripheral edge of the upper end of the main body 13 via a thin hinge 15 at, for example, one corner 12e ′ of the cap 12 obliquely chamfered from above. The direction in which the lid 14 is opened while the finger is locked to the corner 12e at a diagonal position with the corner 12e ′ provided with the portion 15 is the original opening direction (opening / closing direction) X of the thin hinge 15 It has become.

  4 and 5, the cap 12 of the present embodiment has a lid 14 that is connected to the periphery of the main body 13 via a thin hinge 15 so as to be opened and closed. This is a cap that inserts a rod-like protrusion 17 projecting inward from the lid 14 into the spout 16 formed in the central portion and seals the spout 16 when the lid 14 is closed. A pair of engagement walls 19 are formed between the outlet 16 and the connecting portion 18 of the thin hinge portion 15 so as to extend obliquely with respect to the opening / closing direction X of the lid 14 and to be opposed to each other in a substantially C shape. The lid 14 is provided with an engaged wall 20 that protrudes inward to engage with the engaging wall 19 when the lid 14 is closed.

  In the present embodiment, the cap 12 is a synthetic resin molded product, and a cylindrical female screw portion 13 b that protrudes downward from a central portion of the top plate 13 a of the hollow skirt-shaped main body portion 13 is replaced with a head portion of the container main body 11. Attached to the upper end portion of the container body 11 that is also a synthetic resin molded product, with the side surfaces 12d connected to the side surface 11d of the container body 11 (see FIG. 3), by screwing into the male screw provided on 11b. It is done. In addition, the central portion of the top plate 13a of the main body 13 is arranged inside the head 11b of the container main body 11 and the female thread 13b of the cap 12, and for example, a circular spout 16 has an annular protrusion 16a at the periphery. An opening is formed by projecting. A liquid detergent or the like accommodated in the container main body 11 can be poured out through the spout 16, and the spout 16 has, for example, a hollow cylindrical shape protruding downward from the central portion of the lid 14. The bar-shaped protrusion 17 is detachably inserted and locked so that the spout 16 can be opened and closed as the lid 14 is opened and closed.

  The lid 14 is formed integrally with the main body portion 13 with the thin hinge portion 15 interposed therebetween, thereby being connected to the main body portion 13 so as to be openable and closable. The lid 14 has a substantially quadrangular planar shape in which one corner 12 e ′ is chamfered similar to the main body 13, and is formed so that the upper peripheral edge protrudes outward to lock the finger. This makes it easy to open and close. Further, the corner 12e of the lid 14 that is diagonally opposite to the corner 12e 'provided with the thin-walled hinge portion 15 is formed with a finger notch recess 22 by recessing the lower portion of the upper peripheral edge. The correct finger locking position for opening the lid 14 in the original opening direction X of the thin hinge 15 is guided. Further, on the lower surface side of the lid 14, a hollow cylindrical rod-like protrusion 17 and a support cylinder 23 that are concentrically arranged are provided so as to protrude downward from the central portion. The rod-shaped protrusion 17 has an outer diameter substantially equal to the inner diameter of the spout 16, and an annular stepped portion 17a whose outer diameter is slightly larger than the inner diameter of the spout 16 on the outer peripheral surface of the lower end. I have. When the lid 14 is closed until the lower end peripheral portion 14a of the lid 14 contacts the upper end peripheral portion 13c of the main body portion 13, the annular step portion 17a of the rod-shaped protrusion 17 is elastically deformed so as to expand the spout 16. While being inserted into the spout 16 and being locked to the periphery of the lower end of the spout 16, the closed state of the main body 13 and the spout 16 by the lid 14 is detachably locked with sufficient engagement force. Is possible.

  The thin-walled hinge portion 15 that connects the main body portion 13 and the lid 14 of the cap 12 is a well-known thin-walled hinge portion, and as shown in FIG. It is constituted by a pair of possible belt-like portions 25. The thin hinge 15 is disposed between the pair of parallel strips 25 and is elastic as an urging means for urging the main body 13 to open or close the lid 14. A piece 24 is provided, which is a so-called clear tech hinge type hinge.

  In the present embodiment, the top plate 13a of the main body 13 further has an engagement wall 19 disposed so as to be diagonally opposed between the connecting portion 18 and the spout 16 of the thin hinge portion 15 at the periphery. An engaged wall 20 that is formed and engages closely with the engaging wall 19 is provided so as to protrude inside the lid 14. The engaging wall 19 and the engaged wall 20 are simply incorporated as constituent parts of the cap 12 when molding the cap 12 integrally as a synthetic resin molded product with the lid 14 open to the main body 13. And it can provide easily. Further, the engagement wall 19 is located at the side of the thin hinge portion 15 from the spout 16 as a position that does not get in the way when the liquid detergent accommodated through the spout 16 is poured out and does not feel strange in appearance. For example, it is arranged in a substantially square shape so as to oppose between the spout 16 and the connecting portion 18 that are close to each other. On the other hand, the engaged wall 20 is provided at a corresponding position separated from the thin hinge portion 15 by substantially the same distance as the engaging wall 19 so as to protrude inward from the lid 14 as a pair of flat rod members, for example. When 14 is closed, for example, a pair of engaged walls 20 arranged in a substantially C shape is fitted inside a pair of engaging walls 19 arranged in a substantially C shape. By being arranged in this manner, they are engaged in close proximity to each other.

  And according to the cap 12 of this embodiment provided with the above-mentioned structure, the impact etc. at the time of a fall are effectively carried out by the engaging wall 19 and the to-be-engaged wall 20 which can be easily provided at the time of shaping | molding of the cap 12. It is possible to avoid the occurrence of breakage such as pin breakage in the rod-like projection 17 that seals the spout 16 of the main body part 13, and the thin-walled hinge part caused by the twisting force applied to the lid 14. 15 breakage can be improved. That is, according to the present embodiment, when the lid 14 is closed, in addition to the engagement of the bar-shaped protrusion 17 with the spout 16, the engaged wall 20 is engaged so as to be close to the engaging wall 19. Therefore, for example, when receiving an impact at the time of dropping, it becomes possible to effectively support a sudden bending load by the engaged wall 20 engaged with the engaging wall 19, and disperse the bending load. As a result, the impact applied to the rod-shaped protrusion 17 and the load applied to the thin hinge portion 15 can be reduced.

  Furthermore, in the cap 12 of this embodiment attached to the container 10 with a hinge lid having a substantially rectangular outer peripheral cross-sectional shape, as shown in FIG. 2, any one of the four side surfaces 11d and 12d is provided. May be easily recognized as the front surface of the container 10, and the lid 14 may be opened by sliding the finger upward along the side surfaces 11d and 12d recognized as the front surface. In such a case, the sliding direction Y of the finger along the side surfaces 11d and 12d deviates from the original opening direction X of the thin-walled hinge portion 15, whereby the thin-walled hinge portion 15 has a twisting force obliquely upward. Will be loaded. In this embodiment, as described above, the top plate 13a of the main body 13 is engaged with the engaging wall 19 between the connecting portion 18 and the spout 16 of the thin hinge portion 15 on the periphery. A joint wall 20 is provided so as to protrude inside the lid 14, and engages with the lid 14 when the lid 14 is closed. Therefore, these are guided to the original opening direction X of the thin-walled hinge portion 15 as the lid 14 opens from the wrong opening direction along the sliding direction Y, especially when the lid 14 is opened, with these direction regulating means. In the meantime, it is possible to effectively support the torsional force applied to the thin-walled hinge portion 15 and to prevent the thin-walled hinge portion 15 from being damaged.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the engaging wall 19 and the engaged portion 20 provided in the main body 13 and the lid portion 14 may be arranged in a substantially “h” shape as shown in FIG. Further, the engagement wall 19 and the engaged portion 20 may each have a so-called taper whose width or depth is larger in the vicinity of the base than the top portion, so that they can smoothly engage with each other when the lid is opened and closed. It becomes possible.

  In addition, the container with a hinge lid to which the cap of the present invention is attached is not necessarily a container having a substantially rectangular outer peripheral cross-sectional shape, and is a container having various other shapes such as a circular outer peripheral cross-sectional shape. Also good. In addition, the thin hinge portion does not necessarily need to be a clear tech hinge, and the container accommodated in the container may be other various containers other than the liquid detergent. Furthermore, the lid may be directly connected to the container body with the container body closed at the upper part without using the body part as a body part.
