Description

Container {CONTAINER}

The present invention relates to a container.

The present application claims priority based on Japanese Patent Application No. 2014-260413, filed on December 24, 2014, the contents of which are incorporated herein by reference.

BACKGROUND OF THE INVENTION [0002] A hinged cap is known as a cap in a tube container for holding toothpaste or the like, or a bottle container for containing cosmetics and the like. As a specific example of the hinged cap, a lower end of a tubular outer wall is fixed to an upper end of a container body by fitting a foil, and is provided so as to close the upper end of the outer tube wall. A cap provided with an upper lid portion for abutting the main outlet through a hinge portion on a top plate portion formed with an outlet port. The container having such a hinged cap is easy to open the top lid with one hand and therefore is excellent in usability. However, in the hinged cap, as the remaining amount of the contents is reduced, the cap is disturbed and it becomes difficult to extrude the contents. In addition, since the hinged cap generally has a large volume, it is likely to have an image that the contents remain in the cap and can not be used.

Therefore, a container has been proposed in which the hinged cap is screwed on and fixed to the upper end of the container body by screwing (see, for example, Patent Documents 1 to 3). In the container, when the remaining amount of contents becomes small, the contents can be used by separating the hinged cap from the container body. However, in the container, when the remaining amount of the contents becomes small, the hinged cap needs to be rotated several turns to separate it, so that the separation operation of the cap is troublesome.

Further, when exhausting the contents with less remaining amount, a container in which the cap is separated by pressing the opposing portion of the hinge cap on the outer wall of the hinge cap to the inside by pushing up the shoulder of the container body is proposed (Patent Document 4).

However, each time the user uses the container, it is not assumed that the container is selected in accordance with the taste. That is, once the cap is separated from the container body, the cap can not be attached to the container body again.

In addition, as described above, when the volume of the hinged cap increases, the content of the hinged cap remains in the cap, and thus it is easy to have an image that it can not be used. Therefore, the extrusion provided in the cap tends to be smaller than the diameter of the cap . For this reason, for example, in case of a tube container containing toothpaste, it may be difficult to load the contents that have been extruded on a toothbrush.

(Container body)

 The shoulder portion 12 is formed at the upper end of the body portion 10 and is inclined to be gradually narrowed toward the upper side. And a neck portion 14 protruding from the top and having a cylindrical shape with an open upper end.

On the outer peripheral surface of the neck portion 14, an annular first engaging portion 16 projecting radially outward over the entire circumference of the neck portion 14 is provided. The longitudinal cross-sectional shape of the first engaging portion 16 is triangular in this example, but not limited to the triangular shape, and may be semicircular, rectangular or the like.

The neck portion (14) has a large diameter portion (14a) formed below the first engaging portion (16) and having a larger outer diameter than the other portion.

At the lower end of the body 10, an end seal 10a extending in a direction perpendicular to the up and down direction is formed.

As the material of the container main body 2, a known material can be used. For example, a material such as polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP), polyamide (PA), polystyrene Vinyl alcohol copolymer (EVOH), elastomer, polyoxymethylene (POM), silica, glass, metal foil, or a composite material thereof.

(cap)

3 to 8, the cap 3 includes a cylindrical outer cylindrical wall 18, an upper plate portion 20 extending inward from the upper end of the outer cylindrical wall 18 and having a through hole 20a formed therein, A projecting barrel 22 extending upward from the inner periphery of the upper plate portion 20 and a top lid portion 26 formed through the upper plate portion 20 and the hinge portion 24.

The lower end 18a is brought into contact with the shoulder portion 12 when the cap 3 is pushed inward in the radial direction with the cap 3 mounted on the container body 2. [ When the opposed portion of the outer tube wall 18 is pushed inward in the radial direction, the lower end 18a of the outer tube wall 18 abuts against the shoulder portion 12 and the lower end of the outer tube wall 18 18a push up the shoulder portion 12 so that the cap 3 is pushed up and separated from the container main body 2. [

The outer wall 18 has an oblique shape in which the side of the hinge portion 24 in the shape of a circle seen in a plane is linearly cut away and gradually increases in the downward direction. The shape viewed from the bottom face of the lower end 18a of the outer wall 18 is also in the form of an oblique shape in which the circular hinge portion 24 side is straightened.

As described above, according to the present invention, the hinge portion can be fixed to the inner side of the body portion of the container body when seen in a plan view by making the shape of the outer cylinder wall as viewed in plan and the shape seen from the bottom face as a horn- , It is possible to prevent the hinge portion from hanging at the time of use and being difficult to handle. In addition, there is no need to change the size of the filling equipment of the contents, and the filling of the contents becomes easy. By adopting such an arc shape, the radius of the front surface portion and the side surface portion of the outer tube wall can be increased to be equal to the radius of the upper end portion of the torso portion while fixing the hinge portion to the inside of the torso portion when viewed in plan view . As a result, when the opposed portion of the outer cylinder wall is pushed inward in the radial direction, the outer cylinder wall easily pushes up the shoulder portion, so that the cap is easily separated from the container body.

In the case where the shape seen from the plane of the outer wall and the shape seen from the bottom face are formed in an oblique shape in which the hinge portion side is scraped off, the size of the cut- It is desirable that the angle is in the range of 60 to 150 degrees.

The portion 18b of the lower end 18a of the outer wall 18 on the side of the hinge portion 24 on the rear side has a shape of the shoulder portion 12 when viewed from the front, As shown in Fig.

The lower end 18a of the outer cylindrical wall 18 does not press the cap 3 toward the shoulder in the state where the cap 3 is attached to the container main body 2 in a state in which the opposed portion of the outer cylindrical wall 18 is not pressed inward in the radial direction The shoulder portion 12 is preferably spaced apart from the shoulder portion 12 so as not to contact the shoulder portion 12 even if the portion 12 is curved upward convexly. According to the present invention, in the case where the shape viewed from the bottom of the lower end of the outer wall is formed in an oblique shape with the hinge portion side cut away, even if the shoulder portion is curved convex upward, the lower end of the outer tube wall is separated from the shoulder portion . Thus, when the remaining amount of the contents is small, it is possible to prevent the cap from being unexpectedly separated even if the shoulder portion is curved convexly upward by covering the upper portion of the body portion of the container body.

The distance between the lower end of the outer cylinder wall and the shoulder portion in a state in which the opposed portion of the outer cylinder wall is not pressed inward in the radial direction can be appropriately set within a range in which the outer cylinder wall pushes the shoulder portion when the outer cylinder wall is pushed . The distance may be, for example, 0 to 2.0 mm. When the lower end of the outer tube wall is separated from the shoulder portion so as not to come into contact with the shoulder portion even when the shoulder portion is curved convex upward, the distance is preferably set to 0.1 to 1.0 mm.

As shown in Fig. 7, in the portion of the outer cylinder wall 18 which faces the hinge portion 24 and is opposed to the hinge portion 24 in the Y direction perpendicular to the X direction connecting the opposite side thereof, And a pressing position indicating portion 19 indicating a pressing position inside is provided. In the present invention, when the outer shape of the outer wall is an oblique shape as described above, it is preferable to provide a pressing position indicating portion on a portion of the outer tube wall facing in the Y direction.

In the case where the shape seen from the plane of the outer wall is in the shape of an obliquely curved shape on the side of the hinge portion, the portion of the outer tube wall which opposes the opposing portion in the Y direction is a portion opposed to the outer tube wall in the X direction It is easy to push up the shoulder portion of the outer wall as compared with the case of pressing. Therefore, it is possible to easily separate the cap from the container body by providing the pressing position indicating portion and urging the pressing position indicating portion to be pressed.

The pressing position display portion 19 of this example is formed of a plurality of convex tongues extending in the vertical direction and projecting outward from the outer surface of the outer tube wall 18. [ The state of the pushing position display section is not limited to the form of a plurality of convex troughs, and may be formed by printing or the like.

The shape seen from the front face of the pressing position indicating portion 19 is approximately semicircular in this example. The shape viewed from the front of the pressing position indicating portion may be a rectangular shape or the like.

The upper surface of the upper plate 20 is in the shape of a rectangle as that of the outer tube wall 18 and has a circular through hole 20a formed in the center thereof. The diameter of the through-hole 20a is substantially equal to that of the large-diameter portion 14a of the neck portion 14. The large diameter portion 14a of the neck portion 14 is fitted into the through hole 20a of the top plate portion 20 while the cap 3 is mounted on the container body 2, The upper portion of the large-diameter portion 14a protrudes upward from the upper plate portion 20.

In the present invention, it is preferable that the bending rigidity of the upper plate portion in the cap is higher than the bending rigidity of the outer tube wall. As a result, when the opposed portion of the outer tube wall is pushed inward in the radial direction, the top plate portion is deformed due to the deformation of the outer tube wall, so that the top lid portion can be prevented from unexpectedly opening.

The form for increasing the bending rigidity of the upper plate portion to be higher than the bending rigidity of the outer tube wall is not particularly limited and the upper plate portion may have a thickness larger than the outer tube wall thickness and the upper plate portion may be formed of a material having a higher bending rigidity than the material forming the outer tube wall A shape in which ribs are provided on the upper plate portion to reinforce the ribs, and the like. Among them, a shape in which the thickness of the upper plate portion is thicker than the thickness of the outer cylinder wall is preferable in that the manufacturing is easy.

The projecting barrel 22 is provided so as to extend upward from the inner periphery of the upper plate 20, that is, the periphery of the through hole 20a in the upper plate 20. The projecting barrel 22 is cylindrical. The inner diameter of the projecting barrel 22 is substantially equal to the outer diameter of the large diameter portion 14a of the neck portion 14 of the container body 2. The inner diameter of the neck portion 14a of the container body 2 (14) is inserted into the large-diameter portion (14a).

It is preferable that at least one notch portion extending downward from the upper end of the projecting barrel portion in the circumferential direction is formed in the projecting barrel portion. This makes it easier to fit the neck portion of the container main body into the protruded barrel portion so that the first engaging portion and the later-described second engaging portion are engaged with each other. The number of the notch portions formed in the projecting barrel portion is not particularly limited and may be one or more.

In this example, the portion of the projecting barrel 22 including the front side portion opposite to the hinge portion 24 is cut off to form the notch portion 22a. Since the notch portion 22a is formed on the front surface portion of the protruding barrel 22, it is easy to put the content of the neck portion 14 on the toothbrush or the like.

The notch portion formed in the projecting barrel portion may be slit-shaped.

A second engaging portion 28 extending in the circumferential direction of the inner circumferential surface 22b and formed of a convex portion protruding inward in the radial direction is provided at a portion near the upper end of the inner circumferential surface 22b of the projecting barrel 22.

The protruding barrel 22 has flexibility and the neck portion 14 of the container body 2 is fitted into the protruded barrel portion 22 of the cap 3 so that the cap 3 is inserted into the container body 2 The first engaging portion 16 and the second engaging portion 28 form an engagement structure. Specifically, the second engaging portion 28 is engaged with the lower side of the first engaging portion 16 to be locked, thereby forming the engaging structure.

When the opposed portion of the outer tube wall 18 is pressed inward in the diametrical direction with the cap 3 mounted on the container body 2, the outer tube wall 18 pushes up the shoulder portion 12, The engaging structure of the engaging portion 16 and the second engaging portion 28 is released so that the cap 3 is pushed up and separated from the container body 2. [

Although the longitudinal cross-sectional shape of the second engaging portion 28 is a triangular shape in this example, it is not limited to a triangular shape, and may be a semicircular shape, a rectangular shape, or the like.

The hinge mechanism of the hinge portion 24 is not particularly limited and may be, for example, a one point type, a two point type, a three point type, a butterfly type, a snap fit type, a spring fitting type or the like.

An annular projecting portion 30 extending from the lower surface of the top lid portion 26 is formed at the center of the top lid portion 26. The upper end portion of the neck portion 14 protruding from the through hole 20a of the upper plate portion 20 is fitted into the inside of the protruding portion 30 in a state where the cap 3 is attached to the container main body 2, Is prevented from leaking. That is, the top lid portion 26 is configured to open and close the upper opening portion 14b of the neck portion 14 in a so-called outer ring manner. As a result, leakage of contents is suppressed in a state in which the top lid portion 26 is closed.

In the container of the present invention, the inner ring method may be employed or the inner boss method may be employed.

On the opposite side of the hinge portion 24 of the top lid portion 26, a finger holding portion 32 protruding outward in the radial direction is formed. As a result, the upper lid part 26 can be easily opened by holding the finger on the finger latching part 32.

The shape and size of the finger hook 32 are not particularly limited and can be appropriately set according to the size of the cap 3 and the like.

The material of the cap 3 is not particularly limited as long as it is a material commonly used in the cap, and examples thereof include PP, PE, PA, PET, PS, metal, or a composite material thereof.

(Manufacturing method)

The production method of the container 1 is not particularly limited. For example, a cylinder made of a laminate, which forms the body 10 at the lower end of the shoulder portion 12 of the molded body in which the shoulder portion 12 and the neck portion 14 are integrated, A method of filling the contents from the bottom of the cylinder with the cap 3 mounted on the bottom of the cap 3 and sealing the bottom to seal the body 10 to form the container 1 .

The shoulder portion 12 and the neck portion 14 can be integrally formed by, for example, compression molding, injection molding, blow molding, or the like. The cap 3 can be formed by injection molding or the like.

(contents)

The content to be contained in the container of the present invention is not particularly limited and includes, for example, toothpaste, food (dough-shaped horseradish, mustard), medicine (ointment etc.), quasi-drugs (skin cream, shampoo rinse, etc.) A paste form is exemplified.

(Action effect)

Hereinafter, the operation of the container 1 will be described.

When the container 1 is used, the user can arbitrarily select the opening type according to his / her taste every time. Specifically, for example, by holding the upper end portion of the body portion 10 of the container body 2 and opening the upper lid portion 26 by holding the finger on the finger hook portion 32, The contents can be poured out from the top opening 14b of the container.

The lower end 18a of the outer tube wall 18 is pressed against the surface of the shoulder portion 12 by pressing the portion of the opposed pushing position indicating portion 19 in the Y direction of the outer tube wall 18 inward in the radial direction And the cap 3 is pushed up so that the engaged state of the first engaging portion 16 and the second engaging portion 28 is released. Thus, in the container 1, the cap 3 can be easily separated from the container body 2 by one-touch operation. Particularly, when the remaining amount of the contents is small, the contents can be easily used because the cap 3 can be separated by the one-touch method.

In the container 1, the projecting barrel 22 is provided upwardly from the top plate portion 20 and the second engaging portion 28 provided on the projecting barrel 22 is provided with the first engaging portion 28 provided on the neck portion 14 The length of the portion protruding upward from the through hole 20a of the top plate portion 20 in the neck portion 14 can be made sufficiently long in the vertical direction. For this reason, it is easy to carry out work for putting the contents extruded from the neck portion 14 on a toothbrush or the like. In the container 1, since the upper end side portion of the neck portion 14 of the container body 2 protrudes from the through hole 20a of the upper plate portion 20 of the cap 3, the neck portion 14 itself can be used as a spout. As a result, since the cap 3 is not excessively enlarged, it is possible to secure a sufficiently large portion (the neck portion 14) as compared with the extrusion portion of the conventional hinged cap, so that handling is easy when the contents are fed Do.

As described above, in the container of the present invention, the user can select the opening method according to his / her taste, easy to use the contents, and easy to handle even when the contents are fed.

Further, the container of the present invention is not limited to the container 1 described above.

For example, the upper plate portion of the cap is not limited to the flat plate shape but may be an upper plate having a lower inner portion than the radially outer portion. Concretely, for example, the container 4 shown in Fig. 9 may be used. 8 are denoted by the same reference numerals, and a description thereof will be omitted.

The container 4 is the same as the container 1 except that it has an outer tube wall 18A instead of the outer tube wall 18 and a cap 3A having an upper plate portion 20A instead of the upper plate portion 20. [

The upper plate portion 20A has a first annular plate portion 20b extending inwardly from the upper end of the outer cylindrical wall 18A, a cylindrical portion 20c extending in a cylindrical shape from the inner peripheral edge of the first annular plate portion 20b, And a second annular plate portion 20d extending inward from the lower end of the second annular plate portion 20d. The center portion of the second annular plate portion 20d of the upper plate portion 20A has a diameter substantially equal to the outer diameter of the large diameter portion 14a of the neck portion 14 as in the through hole 20a in the container 1, Through holes are formed. Further, a projecting barrel 22 is provided upward from the inner periphery of the second annular plate portion 20d.

The outer tube wall 18A has the same shape as the outer tube wall 18 except that the height of the outer tube wall 18A in the vertical direction is higher than that of the outer tube wall 18. [

As described above, in the vessel 4, the height of the radially inner portion of the top plate portion 20A is one step lower than the height of the radially outer portion, The height of the outer wall 18A in the vertical direction is increased. Thereby, in the vessel 4, it is easy to press the portion of the outer tub wall 18A opposite to the hinge portion 24 in the X direction connecting the hinge portion 24 inward in the radial direction, The outer cylinder wall 18A is easily pushed up, and the cap 3A is easily separated.

In addition, in the container 4, as in the case of the container 1, the user can arbitrarily select the opening type according to his or her preference. When the remaining amount of the contents is small, the cap 3A can be easily separated by one- And it is easy to handle when the contents are fed out.

Further, the container of the present invention may be the container 5 illustrated in Fig. 9 are denoted by the same reference numerals, and a description thereof will be omitted. The container 5 does not have the first annular plate portion 20b and the cylindrical portion 20c at the portion of the upper plate portion 20A of the container 4 opposite to the hinge portion 24, Is the same as the container 4 except that the second annular plate portion 20d has an upper plate portion 20b extending from the large diameter portion 14a side to the outer cylindrical wall 18A. In this type of container, since the outer tube wall 18A is lowered on the front surface side of the neck portion 14, it becomes easier to put the contents that have been extruded from the neck portion 14 on a toothbrush or the like.

In the container of the present invention, the combination of the first engaging portion and the second engaging portion forming the engaging structure is the same as the combination of the first engaging portion 16 and the second engaging portion 28 in the containers 1, 4, And the like. For example, the engaging structure may be formed by forming a groove in the circumferential direction on the outer circumferential surface of the neck portion, and engaging with the second engaging portion formed of the convex trough of the cap.

In the case of the container of the present invention, the shape of the outer cylinder wall may be circular or curved in a circular shape on the side of the hinge portion. Likewise, the shape viewed from the bottom of the lower end of the outer wall may be either an oblique shape in which the hinge side in the circular shape is curved or a circular shape. Further, the outer tube wall may not be gradually enlarged toward the downward direction.

Further, in the case of the container of the present invention, in the case where the shape of the outer cylinder wall is circular and the shape of the outer cylinder wall is circular, the lower end of the outer cylinder wall may be in contact with the shoulder portion in a state in which the cap is mounted on the container body.

In addition, it is also possible to provide a load without providing the pressing position indicating portion on the portion of the outer cylinder wall facing in the Y direction.

The container of the present invention may be a container in which the bending rigidity of the upper plate portion in the cap is not higher than the bending rigidity of the outer tube wall. In addition, the portion of the projecting barrel on the side opposite to the hinge portion is not cut off, which is also a good contribution.
