Description

  The present invention relates to a container with a cap.

In a screw-type container with a cap, if the cap is not completely closed, there is a possibility that the closed portion is loosened and liquid leakage occurs. Therefore, for example, a concave and convex engaging portion that is engaged when the cap is tightened into the container body without loosening is provided at a corresponding portion between the container body side and the cap side, and the user is notified of the completion of tightening when engaged. The thing which produced the click feeling is known. As a result, the effect of preventing loosening can be expected even when subjected to some impact due to dropping or the like.
However, in the type having the action of preventing loosening and generating a click feeling, the engaging portion is easily worn. When wear occurs, the appearance deteriorates and the click feeling also weakens, so that the feeling of use deteriorates.

  Therefore, a container with a cap that can exhibit a click feeling and reduce wear of the engaging portion has been proposed (Patent Document 1).

  This cap-equipped container has a container body with a first engaging rib attached to a portion of the shoulder portion in the circumferential direction, and an outer periphery from the outer peripheral portion of the top plate. A wall part and an inner peripheral wall part depending from the center of the back surface of the top plate, and a cap screwed on the outer surface of the mouth and neck part and a fitting attached to the upper part of the inner peripheral wall part. When a leaf spring is suspended from the mating ring and positioning means having a second engagement rib attached to the inner surface of the lower end portion of the leaf spring, the cap is rotated in the closing direction to reach a predetermined closing position. And a positioning member provided so as to generate a click feeling when the second engagement rib gets over the first engagement rib.

Reality 5-7157

  In the configuration of Patent Document 1, when the second engagement rib of the positioning means gets over the first engagement rib on the mouth-and-neck portion side to produce a click feeling, the leaf spring provided with the second engagement rib is on the side. It has been devised so as to alleviate the impact acting on the second engagement rib to some extent by elastically deforming outward. However, in such a configuration, the leaf spring may be bent or elastically fatigued by being deformed outward, and the length and strength of the leaf spring must be designed to avoid such a problem. Further, in order to allow the leaf spring to be deformed laterally outward, a deformation allowance of the leaf spring must be ensured between the leaf spring and the outer peripheral wall portion. In consideration of such design constraints, the applicant incorporates a positioning means with a second engagement rib between the outer peripheral wall portion and the inner peripheral wall portion of the cap so as to be biased downward. I came up with the idea of alleviating the collision force. However, when the cap has a substantially oval shape, it is easy to apply a force when turning the cap. Therefore, it cannot be said that there is no risk of the second engagement rib being deformed by an excessive pressure contact force. When the rib is deformed, an appropriate click feeling cannot be obtained.

  An object of the present invention is to prevent a complicated structure and an increase in manufacturing cost in a capped container that generates a click feeling when the lid is closed.

The first means stands the mouth and neck portion 10 from the trunk portion 4 via the shoulder portion 6, and the container body 2 having the first engagement portion 8 attached to a part of the shoulder portion 6 in the circumferential direction;
The outer peripheral wall portion 34 is suspended from the outer peripheral portion of the top plate 32, and the inner peripheral wall portion 36 is suspended from the center of the back surface of the top plate 32, and the inner peripheral wall portion 36 is screwed to the outer surface of the mouth and neck portion 10. A cap 30;
The cap 30 is assembled between the outer peripheral wall portion 34 and the inner peripheral wall portion 36, has a leg cylinder portion 52 surrounding the inner peripheral wall portion 36, and the leg cylinder portion 52 is connected to the inner peripheral wall portion 36. The second engagement portion 56 is attached to the lower end side of the leg tube portion 52 and can be brought into contact with the back surface of the top plate 32 from the upper end side of the leg tube portion 52. When the leaf spring 62 protrudes upward and the cap 30 is rotated in the closing direction to reach a predetermined closed position, the second engagement portion 56 gets over the first engagement portion 8, thereby causing a click feeling. In a container with a cap comprising a positioning member 50 provided to produce
The planar shape of the container body 2 and the cap 30 is formed into a substantially oval shape having a major axis in the same direction when the cap 30 is in the closed position, and the leaf spring 62 is second when viewed from above. It provided in the location which shifted | deviated from the formation location of the engaging part 56. FIG.

  In this means, in the positioning member 50 assembled to the elliptical cap 30 as shown in FIG. 4, the leaf spring 62 is shifted from the formation position of the second positioning second engaging portion 56 when viewed from above. Provided. If the planar shape of the cap 30 is an ellipse, a force is easily applied during the operation of rotating the cap 30, and thus the above shape is used to avoid deformation of the second engaging portion 56. A more preferable aspect of the present invention will be described with the means described below.

The second means includes a first means, and the second engagement portion 56, when viewed from above, so as to form in the vicinity of the short-diameter shaft A _S of the cap 30 of the substantially elliptical shape, a plate The spring 62 was provided at a location shifted from the vicinity of the short axis A _{S when} viewed from above.

In this means, as shown in FIG. 4, the second engagement portion 56, when viewed from above is provided in the vicinity of the short-diameter shaft A _S of the ellipse (e.g. the left-right direction intermediate portion 50A of FIG. 8), the leaf spring 62 It proposes providing at a position deviated from the vicinity of the short-diameter shaft a _S (e.g. left side 50B and the right side 50C of the positioning member 50 shown in FIG. 8). Thereby, the press-contact force to the 2nd engaging part 56 can further be relieve | moderated.

The third means includes the second means, and the positioning member 50 projects the outward flange-like plate portion 58 from the upper part of the leg tube portion 52, and the outward flange-like plate portion 58 The leaf spring 62 is erected from an appropriate position on the outer periphery, and the outward flange-like plate portion 58 is extended in the direction of the major axis A _L of the cap 30 to provide a pair of extension plate portions 64. These extension plate portions 64 tip portions were fitted into the inner corner portion 35 of the outer peripheral wall portion 34 as viewed from above.

  This means has a structure in which the tip of the extension plate 64 is fitted into the inner corner 35 of the outer peripheral wall 34 shown in FIGS. Thereby, in particular, since the positioning member 50 is assembled in the outer peripheral wall portion 34 of the cap 30, the second engaging portion 56 is coupled to the first engaging portion 56 in combination with the planar shape of the cap 30 being substantially elliptical to which a force is easily applied. There is a possibility that the engagement portion 8 is pressed more strongly. However, even in such a structure, the contact of the second engagement portion 56 with respect to the first engagement portion 8 is alleviated by the first means, so that deformation of the second engagement portion 56 can be avoided.

Incidentally, the container body 2 may be molded using a mold having a crack line (parting line) in the direction of its major axis d _L. Thereby, since the crack line of a container body does not come to the short diameter side used as the front surface of a normal container, it can avoid impairing the external appearance as a container.

According to the first aspect of the invention, since the positioning member 50 protrudes the leaf spring 62 upward from the upper end side of the leg tube portion 52 provided with the second engagement portion 56, the second engagement portion 56 is Since the second engagement portion 56 can be prevented from being scraped when the first engagement portion 8 is climbed over, and the leaf spring 62 is displaced from the formation position of the second engagement portion 56 as viewed from above, the second engagement portion can be further removed. Wear of the joint portion 56 can be reduced.
According to the invention according to the second means, the second engagement portion 56, when viewed from above is formed in the vicinity of the short-diameter shaft A _S of the cap 30 of a substantially elliptical shape, and a plate spring 62 shorter diameter shaft Therefore, the wear of the second engaging portion 56 can be further reduced.
According to the invention according to the third means, also the inner corners a pair of extension plate portion 64 extending from the outward flange-like plate portion which is attached to leg tube portion 52 in the direction of the major axis axis A _L of the outer peripheral wall portion 34 Since the positioning member 50 is inserted, the positioning member 50 can be reliably assembled in the cap 30, and the force with which the second engaging portion 56 gets over the first engaging portion 8 increases.

  1 to 12 show a container with a cap according to a first embodiment of the present invention. The container with a cap is composed of a container body 2, a spout 20, a cap 30, a seal member 40, and a positioning member 50. Among these members, the container body 2 can be formed of a hard material such as glass or a synthetic resin material, and the other members can be formed of a synthetic resin material.

The container body 2 is formed by raising the mouth and neck portion 10 from the trunk portion 4 through a tapered tapered shoulder portion 6. The trunk portion 4 has an elliptical cylindrical shape, and is larger than the lateral diameter (longitudinal diameter d _L ) of FIG. 1 and larger than the lateral diameter (short axis d _{S of the} trunk portion) of FIG. In this specification, the direction of the major axis of the body part 4 is referred to as the left-right direction, and the direction of the minor axis of the body part 4 is referred to as the front-rear direction.

  A first engaging portion 8 is provided on the short diameter side of the shoulder portion 6, that is, on both the front and rear sides. As shown in FIG. 5, the first engaging portion 8 in the illustrated example is positioned in the closing rotation direction of the cap 30 with respect to the main convex portion 8 a for the second engaging portion 56 to be described later to get over, and the main convex portion 8 a. And a convex stopper 8b. A gap G for fitting the second engaging portion 56 is provided between the main convex portion 8a and the convex stopper 8b.

  An annular locking groove 12 is formed at the upper end of the mouth-and-neck portion 10, and a screw portion 14 is formed on the outer surface of the mouth-neck portion below the locking groove 12.

  As shown in FIG. 1, the pouring plug 20 has an outer cylindrical portion 26 from the outer peripheral portion of the plug plate portion 24 having a pouring hole 22 in the center, and an inner cylindrical portion 28 from the inner peripheral portion of the back surface of the plug plate portion 24. Is suspended in a double cylinder shape. The outer cylinder portion 26 is fitted in the locking groove 12 of the mouth / neck portion 10. The structure of the spout 20 can be changed as appropriate.

  The cap 30 hangs an outer peripheral wall portion 34 having a substantially elliptical section from the outer peripheral portion of the substantially elliptical top plate 32 and an inner peripheral wall portion 36 having a circular cross section from the center of the back surface of the top plate 32. On the outer surface of the inner peripheral wall portion 36, a rotation-preventing protrusion 38 is vertically provided (see FIG. 5). The lower half portion of the inner peripheral wall portion 36 forms a large inner diameter portion 36a, and a screw groove that is screwed with the screw portion 14 of the mouth neck portion 10 is formed in the large inner diameter portion. The position of the cap 30 when the screw groove of the inner peripheral wall portion 36 is tightened to the screw portion of the mouth / neck portion 10 to the end is referred to as a “closed position” in this specification. In the illustrated example, at the closed position, the lower end portion of the outer peripheral wall portion 34 is formed so as to approach the shoulder portion 6. Further, a first short cylinder portion 39 is suspended from the central portion of the top plate 32 of the illustrated cap 30. The cap 30 is preferably formed by a mold, and is particularly preferably formed by a mold having a crack line in the direction of the major axis of the ellipse.

  As shown in FIG. 2, a rib 33 is formed on the short axis side of the outer peripheral portion of the back surface of the top plate 32, and an upper end portion of a plate spring 62 described later is formed on this rib.

  As shown in FIG. 3, the seal member 40 is configured such that the second short cylinder portion 44 is erected from the upper surface of the closing plate portion 42, and an O-ring 46 is fitted to the outer surface of the second short cylinder portion 44. When the second short tube portion 44 is fitted to the outside of the first short tube portion 39, the closing plate portion 42 closes the pouring hole 22, and the O-ring 46 is connected to the closing plate portion 42 and the ceiling. It is provided so as to be sandwiched between the plates 32 in a liquid-tight manner.

  As shown in FIG. 7, the positioning member 50 has a leg cylinder part 52 with a pair of second engagement parts 56 attached to the lower end part. The leg cylinder part 52 is connected to the inner peripheral wall part 36 of the cap 30. The outer surface is fitted so as to be movable up and down. As shown in FIG. 6, a pair of receiving grooves 54 opened inward and upward are provided vertically on the inner surface of the leg tube portion 52, and the above-described rotation-fixing protrusions 38 are inserted into the receiving grooves 54. Thus, the leg cylinder part 52 is formed so as not to rotate with respect to the inner peripheral wall part 36.

  Further, an outward flange-like plate portion 58 is attached to the upper end of the leg tube portion 52. The outer peripheral portion of the outward flange-like plate portion 58 is raised upward to form an annular rim portion 60. A plurality of leaf springs 62 are erected from the annular rim portion 60.

In the illustrated example, the second engaging portion 56 is formed of a substantially trapezoidal base portion 56b when viewed from below and a rectangular front portion 56a when viewed from below (see FIG. 11). Tip surface S ₁ of the front portion 56b shown in FIG. 11 are perpendicular flat surface to produce a click feeling. The lower surface S ₂ of the previous section 56a as the inclined surface of the upper inwardly as shown in FIG. 10, runs on the main protruding portion 8a of the first engagement portion 8 are easily formed. These shapes can be modified as appropriate.

  With the above configuration, when the cap 30 assembled with the positioning member 50 is screwed into the mouth-and-neck portion 10, as the cap 30 approaches the closed position, the leaf spring 62 becomes the back surface of the top plate 32 of the cap 30 as shown in FIG. The second engaging portion 56 of the leg tube portion 52 is brought into pressure contact with the shoulder portion 6 by the elastic force of the leaf spring 62. When the second engaging portion 56 comes into contact with the main convex portion 8a of the first engaging portion 8, the plate spring 62 is further elastically deformed, so that the second engaging portion 56 gets over the main convex portion 8a. Therefore, excessive stress does not act on the second engagement portion 56, and the second engagement portion 56 is prevented from being crushed or deformed.

In the present invention, the second engagement portion 56 is provided in the direction of the short diameter shaft A _S of the cap 30 incorporating the positioning member 50. That is, the second engagement portion 56 is disposed in the lateral direction middle portion 50A in the vicinity of the short-diameter shaft A _S. The plurality of leaf springs 62 are disposed so as to be shifted from the installation location of the second engaging portion 56 and positioned on the left side portion 50B and the right side portion 50C of the positioning member 50.

If the second engaging portion 56, providing in the direction of the major axis axis A _L, the first engagement portion 8 of the container 2 must also be provided in the major axis direction of the container body. If it becomes so, the dividing line of the metal mold | die for shape | molding the container body 2 will come to a short diameter direction. In general, in the case of an elliptical container, since the minor axis side is the front, traces of the dividing line will appear on the front of the container body, the appearance will be poor, and printing problems will occur. According to the configuration of the present invention, these disadvantages can be avoided.

  Further, as described above, when the leaf spring 62 is disposed directly above the second engaging portion 56 for alignment, the leaf spring directly presses the second engaging portion, so that the opening / closing operation becomes hard, and Although the joint portion is apt to be crushed, in the present invention, the second engagement portion 56 is displaced from the place where the leaf spring 62 is installed. Further, when the cap 30 is transparent or opaque, when the leaf spring 62 is positioned on the center line of the container body 30 when viewed from the front of the container body 30, the appearance of the container body is deteriorated. According to this, since the leaf spring 62 is shifted from the center line viewed from the front direction, the appearance is not impaired.

In the preferred illustrated embodiment, the outward flange-like plate portion 58, and extends in the direction of the major axis axis A _L of the elliptical cap 30, forming a pair of extension plate portion 64. The tip portions of these extension plate portions 64 are shaped to fit the inner corner portion 35 of the outer peripheral wall portion 34 of the cap 30. Thereby, the engagement force between the tip portion of the extension plate portion 64 and the outer peripheral wall portion 34 of the cap 30 is improved. When the positioning member 50 is assembled in the elliptical cap 30 as described above, an excessive pressure contact force is likely to act on the second engaging portion as compared with the perfect cap, but the configuration of the present invention described above. Thus, the inconvenience that the second engaging portion is crushed can be surely avoided.

  Since the second engaging portion 56 and the first engaging portion 8 are positioned in the minor axis direction of the ellipse that is the planar shape of each of the cap 30 and the container body 2, the container body 2 is arranged in the major axis direction as described above. It is suitable to form with the metal mold | die (not shown) which has a crack line. As a result, it is possible to avoid crack lines in the front direction of the container body and the like, the appearance of the product can be improved, and problems such as printing do not occur.
