Description

  The present invention relates to a container with a hinge lid, and more particularly, to a container with a hinge lid having a lid that is connected to the periphery of a main body through a thin hinge portion so as to be opened and closed.

  The hinged lid is connected to the top edge of the main body by the container body closed at the top and the top edge of the main body by the cap attached to the top of the container body so that it can be opened and closed via a thin hinge. Thus, the lid can be opened and closed to open or close the spout provided in the main body. The thin hinge portion of the container with the hinge lid is generally constituted by a belt-like portion that can be folded in two because the center is thin, and the belt-like portions are arranged in a pair in parallel, A hinge lid using a so-called three-point hinge that includes an urging means for urging the main body portion between the lid opening side and the closing side is also known (see, for example, Patent Document 1).

Further, the engagement portion provided on the inner side of the lid in the state where the lid is closed with respect to the main body portion or the state where the lid is biased so as to be close to the main body portion by the biasing means By engaging with, for example, the twisting force applied to the lid when the cap is attached to the container body, the impact force applied to the lid when dropped, etc. can be supported, and the thin hinge portion can be prevented from being damaged. Such a cap is also disclosed (for example, see Patent Document 1).

  On the other hand, due to the diversification of products and containers in recent years, for example, various containers having a characteristic appearance with excellent design have been developed, and as a container with a hinge lid having a thin hinge part, for example, from the appearance of the entire container In some cases, a container in which it is difficult to distinguish the opening direction by the thin hinge portion is used. In such a container with a hinge lid, depending on the user, the lid may be opened by recognizing a direction different from the original opening direction of the thin hinge portion as the opening direction of the lid. An excessive twisting force may be applied to the thin hinge portion.

  However, since the conventional container with a hinge lid does not have means for restricting the opening direction of the thin-walled hinge portion at the start of opening the lid, when the lid is opened in a direction different from the original opening direction of the thin-walled hinge portion. From such a wrong opening direction, until the lid is opened, it is guided to the original opening direction of the thin hinge part, and an excessive twisting force is applied to the thin hinge part, The thin hinge portion is easily damaged. Further, in the means for preventing the thin hinge portion from being damaged by engaging the engaging portion described in Patent Document 1 with the engaged portion, the lid is closed by the urging means or the state where the lid is closed with respect to the main body portion. Can be supported by twisting force, impact force, etc., but the engagement area is small, so when the lid starts to open, After the lid is opened to some extent, it is difficult to sufficiently support the twisting force applied to the thin hinge portion.

  The present invention can regulate the opening direction of the thin-walled hinge portion at least at the start of opening of the lid, and effectively supports the twisting force until the lid is guided in the original opening direction of the thin-walled hinge portion. An object of the present invention is to provide a container with a hinge lid capable of preventing the thin hinge portion from being damaged.

  The present invention is a container with a hinge lid having a lid that is openably and closably connected to the periphery of the main body portion via a thin hinge portion, and restricts the opening and closing direction of the thin hinge portion when the lid is opened and closed. The main body portion and the lid are provided in proximity to the thin hinge portion, and the direction restricting means is attached to the lid and extends from the upper outer peripheral surface sandwiching the thin hinge portion to the outside of the thin hinge portion. A circular projection extending around and extending downward, and formed on a lower outer circumferential surface sandwiching the thin hinge portion of the main body, and comprising a guide opening having a width similar to the width of the circular projection, Provided is a container with a hinge lid that regulates the opening and closing direction of the thin hinge portion by sliding the circular protrusion with the guide opening while keeping a side edge along the opening edge of the guide opening when the lid is opened and closed. By It is obtained by achieving the above object.

  According to the container with a hinge lid of the present invention, it is possible to regulate the opening direction of the thin hinge portion at least at the start of opening of the lid, and torsional force until the lid is guided in the original opening direction of the thin hinge portion. Can be effectively supported so that the thin hinge portion is not damaged.

  As shown in FIGS. 1 and 2, the hinge-lid container 10 according to a preferred embodiment of the present invention has a cap 12 mounted on the upper part of a container main body 11 containing a liquid detergent such as shampoo. It is comprised by. The cap 12 has a main body portion 13 disposed so as 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 FIGS. 4A and 4B), and a thin hinge portion 15. It comprises a lid 14 connected to the peripheral edge of the main body 13 of the cap 12 so as to be opened and closed. In the first embodiment, the body portion 11c of the container body 11 has a substantially rectangular outer circumferential 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. In addition, the cap 12 connected to the body portion 11c also has a substantially quadrangular 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. ing. 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 whose upper part is obliquely chamfered. 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.

  On the other hand, in the container 10 with a hinge lid of this embodiment having a substantially quadrangular outer peripheral cross-sectional shape, it is easy to recognize any one of the four side surfaces 11d and 12d as the front surface of the container 10, 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 a twisting force is applied to the thin-walled hinge portion 15. become. In the first embodiment, by providing the direction regulating means 16 to be described later, particularly when the lid 14 is opened, the original of the thin hinge portion 15 is opened as the lid 14 is opened from the opening direction along the sliding direction Y. Such a twisting force is effectively supported until it is guided in the opening direction X, so that the thin hinge portion 15 can be prevented from being damaged.

  And the container 10 with a hinge lid of this embodiment is a container which has the lid | cover 14 connected with the upper-end periphery of the main-body part 13 of the cap 12 through the thin hinge part 15 so that opening and closing was possible, A direction restricting means 16 for restricting the opening and closing direction by the thin hinge portion 15 is provided in the main body portion 13 and the lid 14 in the vicinity of the thin hinge portion 15, and this direction restricting means 16 is attached to the lid 14, and is provided with the thin hinge portion. Formed on the outer peripheral surface of the thin hinge portion 15 and extending downward from the upper outer peripheral surface sandwiching the thin hinge portion 15, and the lower outer peripheral surface of the main body portion 13 sandwiching the thin hinge portion 15 of the main body portion 13. A guide opening 18 having a width b2 similar to the width b1 of 17 and sliding the orbiting projection 17 through the guide opening 18 along the side edge of the opening periphery of the guide opening 18 when the lid 14 is opened and closed. By Closing direction of the wall hinge portion 15 is adapted to regulate the (opening direction) X.

  Moreover, in this embodiment, the circumference | surroundings protrusion 17 is comprised by the strip | belt-shaped plate member curvedly formed by the arc shape.

  In this embodiment, the cap 12 is a synthetic resin molded product and protrudes downward from the central portion of the top plate 13a of the hollow skirt-shaped main body 13 as shown in FIGS. 3 (a) and 3 (b). In a state where each side surface 12d is made continuous with the side surface 11d of the container body 11 by screwing the cylindrical female thread portion 13b to the male screw provided on the head portion 11b of the container body 11 (see FIG. 1), It is attached to the upper end portion of the container body 11 which is also a synthetic resin molded product. In addition, an opening 20 is formed in the center of the top plate 13 a of the main body 13 so as to be disposed inside the head 11 b of the container main body 11 and the internal thread 13 b of the cap 14. The liquid detergent contained in the container body 11 can be poured out through the spout 20, and the open / close rod 21 protruding downward from the center of the lid 14 can be attached to and detached from the spout 20. The spout 20 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 hinge portion 15 is formed with a finger hanging recess 22 by denting 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, an opening / closing rod 21 and a support cylinder 23 arranged concentrically are provided on the lower surface side of the lid 14 so as to protrude downward from the central portion. The open / close rod 21 has an outer diameter substantially the same as the inner diameter of the spout 20 and an annular stepped portion 21 a whose outer diameter is slightly larger than the inner diameter of the spout 20 on the outer peripheral surface of the lower end thereof. ing. 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 21a of the opening / closing rod 21 is elastically deformed so as to expand the spout 20 By being inserted into the spout 20 and locked to the periphery of the lower end of the spout 20, the closed state of the main body 13 and the spout 20 by the lid 14 can be firmly held.

The thin-walled hinge portion 15 that connects the main body portion 13 and the lid 14 of the cap 12 is known as a 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 direction regulating means 16 for regulating the opening / closing direction by the thin hinge portion 15 when the lid 14 is opened / closed is a circuit attached to the lid 14 as shown in FIGS. 2, 3 (a) and 3 (b). The protrusion 17 and the guide opening 18 formed in the main body 13 are configured. Orbiting projection 17, for example, made of the same material as the lid 14, a belt-shaped plate member having a thickness of 0.5~2mm extent, curved in an arc so that vertical shape becomes for example a substantially semicircular shape The one end is joined and fixed to the outer peripheral surface of the peripheral wall 14b in the portion directly above the thin hinge portion 15, and attached to the lid 14 in a cantilever state. The circumferential protrusion 17 has a deformability that can be easily bent and deformed by receiving a load along the longitudinal direction, and can be compressed in the width direction without being easily bent and deformed even when receiving a compressive load in the width direction. It has considerable shape retention rigidity that can support the load. Further, the circumferential projection 17 preferably has a width b1 that fits within the width of the thin hinge portion 15, and extends in parallel with the pair of band portions 25 while circling so as to cover the thin hinge portion 15 from the outside. Even at the time of closing, the lower end portion 17a is attached in a state of being inserted into the guide opening 18 formed in the portion directly below the thin hinge portion 15.

  The guide opening 18 is formed in a portion immediately below the thin hinge portion 15 at the chamfered corner portion 12 e ′ of the main body portion 13 of the cap 12. In the present embodiment, the guide opening 18 has a width b2 slightly wider than the width b1 similar to the width b1 of the circumferential protrusion 17, and a considerable height at which the circumferential protrusion 17 can be loosely fitted up and down. The opening is formed in a rectangular shape including Since the guide opening 18 has a width b2 slightly wider than the same as the width b1 of the circular projection 17, the side edge of the circular projection 17 is provided on the opening periphery of the guide opening 18 when the lid 14 is opened and closed. It is possible to smoothly regulate the opening and closing direction X by the thin hinge portion 15 by smoothly guiding the circular protrusion 17 while being along. Further, since the guide opening 18 has a height that allows the circular protrusion 17 to be loosely fitted up and down, the peripheral protrusion 17 contacts the upper and lower peripheral edges of the guide opening 18 and smoothly slides. It is possible to effectively avoid the obstruction.

  And according to the container 10 with a hinge lid of this embodiment provided with the above-mentioned structure, the opening direction of the thin-walled hinge part 15 can be regulated at least when the cover 14 starts to be opened, and the original opening direction of the thin-walled hinge part 15 Until the lid 14 is guided to X, the torsional force can be effectively supported so that the thin hinge portion 15 is not damaged. That is, according to the present embodiment, the circumferential protrusion 17 that is attached to the lid 14, extends around the outside of the thin hinge portion 15 from the upper outer peripheral surface sandwiching the thin hinge portion 15, and extends downward, and the main body portion 13. Is formed on a lower outer peripheral surface sandwiching the thin hinge portion 15 and includes a direction restricting means 16 having a guide opening 18 having a width b2 similar to the width b1 of the circular protrusion. Following the opening of the lid 14, the circumferential projection 17 is slid while being guided by the guide opening 18 while the side edge of the circumferential projection 17 is aligned along the opening edge of the guide opening 18. The opening direction X of the thin hinge 15 can be regulated over the entire angle region, and the torsional force applied to the thin hinge 15 can be supported. As a result, even when the lid 14 is opened by recognizing the direction Y different from the original opening direction X of the thin hinge 15 as the opening direction of the lid 14, the lid 14 is opened from the wrong opening direction Y. Until the thin hinge part 15 is guided in the original opening direction X, the excessive twisting force is prevented from being applied to the thin hinge part 15 so that the thin hinge part 15 is not damaged. Can be protected.

  In addition, according to the present embodiment, the opening direction by the thin hinge 15 can be regulated in a stable state until the lid 14 is opened at a wide angle close to 180 degrees, and the lid 14 is opened. Not only when closing, it is possible to regulate the closing direction by the thin hinge 15 in a stable state.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the container with a hinge lid of the present invention does not necessarily need to be a container having a substantially rectangular outer peripheral cross-sectional shape, and may be a container having other various shapes such as a circular outer peripheral cross-sectional shape. In addition, it is not always necessary for the container to be difficult to recognize the original opening direction of the thin hinge part, and even if the opening direction by the thin hinge part can be easily distinguished, the lid is opened in the wrong direction. Therefore, the hinge-lid container of the present invention can be preferably used. Further, 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 top without using a cap as a body part.

  Further, the circular protrusion is not necessarily a strip-shaped plate member that is curved in an arc shape, such as a rod-shaped member or a strip-shaped sheet member that is flexible only in the longitudinal direction. Various other members that can be slid while moving along can be used. Further, the guide opening may have a shape other than a rectangular shape such as a circle, an oval, an ellipse, or the like.
