Description

  The present invention relates to a container.

  Examples of containers that contain liquid contents such as softeners and liquid detergents include containers that include a container body and a cap that is attached to the mouth and neck of the container body. As the cap, a measuring cap having a measuring function and having a transparent outer wall so that the measured contents can be visually recognized from the outside is widely used. In the measuring cap, a measuring line or the like is formed as a relief by printing or molding on the measuring tube portion located inside the outer wall portion.

  As a mode of attaching the cap to the mouth and neck portion of the container main body, a mode in which the cap is screwed and attached to the mouth and neck portion in order to prevent the liquid contents from leaking during transportation or handling is common. However, in a container of a type in which the cap is screwed and attached, it is necessary to rotate the cap many times when the cap is attached or removed, and the operation is complicated.

As an aspect in which the cap is attached to the mouth and neck of the container body, an aspect in which the cap is fitted and attached to the mouth and neck has also been proposed.
For example, an engagement concave portion is formed at the lower end portion of the outer wall surface of the tapered mouth-neck portion that decreases in diameter toward the upper end, and an engagement convex portion that fits the engagement concave portion at the lower end portion of the inner wall surface of the cap. The formed container is mentioned (for example, patent document 1). In the container, the engagement concave portion and the engagement convex portion are released from each other by pressing inward the vertical center portions of the opposing side walls of the cap fitted and attached to the mouth and neck portion. In this state, the cap is removed from the mouth and neck by lifting the cap upward.
However, even in the container, a two-stage operation is required for removing the cap, and the operation for removing the cap is complicated.

The depth of the vertical groove portion 21 is shallower than the depth of the concave portion 19, and when the projection portion 29 described later fits into the concave portion 19, the projection portion 29 does not unexpectedly come off upward. Yes.
The depth of the vertical groove portion 21 is constant from the end on the concave portion 19 side to the upper end of the mouth neck portion 9.

As shown in FIG. 4, the cap 3 includes a cylindrical measuring tube portion 22, a lid portion 23 that closes one open end of the measuring tube portion 22, and a flat surface that protrudes outward from the circumferential surface of the measuring tube portion 22. A projecting annular plate part 24 and an outer wall part 25 suspended from the outer edge part of the projecting plate part 24 are provided. As described above, the cap 3 has a cylindrical shape with a lid, and has an overhanging plate portion 24 projecting outward at the center in the height direction. A protruding portion that protrudes outward from the outer edge portion of the overhanging plate portion 24 may be formed outside the outer wall portion 25 of the overhanging plate portion 24.
Further, a ring portion 26 that protrudes downward is formed on the inner peripheral edge portion of the overhanging plate portion 24.
The cap 3 can be rotated around the axis of the mouth / neck portion 9 in a state of being attached to the mouth / neck portion 9.

A part of the lower end side of the measuring cylinder portion 22 is inserted into the cylinder wall portion 10 of the nozzle plug 8 so as to surround the dispensing cylinder 17.
On the portion between the two long pieces 25a on the peripheral wall of the measuring cylinder part 22, as shown in FIG. 4C, a scale part 27 having a scale line for measurement and a number for displaying capacity is printed. It is formed by means such as engraving. Thereby, in the state which turned the cap 3 upside down, the quantity of contents, such as the liquid inject | poured from the opening part 22a of the measurement cylinder part 22, can be grasped | ascertained. Thus, the cap 3 is a so-called measuring cap.

  When the cap 3 is attached to the nozzle plug 8, the overhanging plate portion 24 is placed on the opening at the upper end of the cylindrical wall portion 10 of the nozzle plug 8 in the mouth / neck portion 9.

The outer wall portion 25 includes two long piece portions 25a and two short piece portions 25b.
The long piece portion 25a is a thin piece having a front tongue shape with a width narrowing toward the lower end, and the lower end portion has a curved shape in front view.
Two long piece portions 25a are formed at intervals of 180 ° around the axis of the overhanging plate portion 24, that is, so as to be symmetrical with respect to the central axis C1 when the cap 3 is attached to the mouth-and-neck portion 9. ing. The two long piece portions 25 a are arranged along the portions where the concave portions 18 and the concave portions 19 are provided at symmetrical positions around the axis line on the outer peripheral surface of the cylindrical wall portion 10 when the cap 3 is mounted.

The short piece portion 25b is a rectangular thin piece having a longer length around the axis than the length in the vertical direction when viewed from the front.
The short piece portion 25b is symmetrical with respect to the central axis C1 between the two long piece portions 25a at intervals of 180 ° around the axis of the overhanging plate portion 24, that is, when the cap 3 is mounted on the mouth neck portion 9. Two are formed so as to be positioned. Each of the two short piece portions 25b is formed from one long piece portion 25a to the other long piece portion 25a. That is, the two long piece portions 25a and the two short piece portions 25b are integrally formed in the circumferential direction.
When the cap 3 is attached, the short piece portion 25 b is placed along the upper end side portion of the outer peripheral surface of the cylindrical wall portion 10 of the nozzle plug 8.

  The lower end of the short piece portion 25b is located closer to the overhanging plate portion 24 than the lower end of the long piece portion 25a. That is, the vertical length of the short piece portion 25b is shorter than the vertical length of the long piece portion 25a. Thereby, when measuring the contents in a state where the cap 3 is inverted, the scale portion 27 is easily visible.

  3-10 mm is preferable and, as for the length of the up-down direction of the short piece part 25b, 5-7 mm is more preferable. If the length of the short piece portion 25b in the vertical direction is equal to or greater than the lower limit value, it is easy to suppress leakage of the contents when the cap 3 is attached to the mouth / neck portion 9. If the length of the short piece part 25b in the vertical direction is equal to or less than the upper limit value, the visibility of the scale part 27 at the time of weighing the contents becomes better.

Two protrusions 28 and 29 are provided on the inner surface of the long piece portion 25 a in the outer wall portion 25. The protruding portion 29 is formed on the right side of the protruding portion 28 and on the upper side of the protruding portion 28 in a front view when the outer wall portion 25 is viewed from the outer surface side. The positional relationship between the protrusion 28 and the protrusion 29 is the same as the positional relationship between the recess 18 and the recess 19. When the cap 3 is attached, the projection 28 fits into the recess 18 and the projection 29 fits into the recess 19.
When the cap 3 is attached, the projection 28 and the recess 18 are fitted, and the projection 29 and the recess 19 are fitted, so that the cap 3 can be firmly attached to the mouth-neck portion 9 and the attached cap 3 is prevented from coming off unexpectedly.

  The shape of the projection 28 in front view may be any shape as long as the projection 28 can be fitted into the recess 18, and the cap 3 can be firmly attached to the mouth / neck portion 9. It is preferable that The front-view shape of the protrusion 28 in this example is circular. Note that the front-view shape of the protrusion 28 may be a triangle shape, a rectangular shape, or the like.

The size of the projection 28 in front view is slightly smaller than the size of the recess 18 in front view, and the projection 28 fits into the recess 18. The size of the recess 18 and the projection 28 in front view is such that when the projection 28 and the recess 18 are fitted, the attached cap 3 can be prevented from coming off unexpectedly, and the cap 3 is rotated. What is necessary is just to set suitably so that the protrusion part 28 may remove | deviate from a recessed part when it touches.
The height of the projecting portion 28 from the inner surface of the long piece portion 25a may be any height as long as the projecting portion 28 fits into the recessed portion 18, and can be equal to the depth of the recessed portion 18, for example.

  The front-view shape, the front-view shape size, and the height of the protrusion 29 are the same as the front-view shape, front-view shape size, and height of the protrusion 28. The front view shape of the protrusion 28 and the front view shape of the protrusion 29 may be the same or different. The size of the protrusion 28 and the size of the protrusion 29 may be the same or different. The height of the protruding portion 28 and the height of the protruding portion 29 may be the same or different.

(Production method)
As a manufacturing method of the bottom wall 4, the side wall 5, the shoulder portion 6, and the protruding cylinder portion 7 of the container body 2, for example, a method of integrally molding by blow molding using an olefin-based synthetic resin such as polyethylene can be given. As a manufacturing method of the nozzle plug 8 of the container body 2, for example, a method of integrally molding by injection molding using an olefin-based synthetic resin such as polypropylene can be cited.
Examples of the method for producing the cap 3 include a method in which the cap 3 is integrally molded by injection molding using an olefin-based synthetic resin such as polyethylene.
In addition, the manufacturing method of the container main body 2 and the cap 3 is not limited to an above-described method.

(Function and effect)
Hereinafter, the removal operation of the cap 3 in the container 1, the measurement operation, and the attachment operation will be described.
In the container 1 before use, as shown in FIG. 2 (b), the inner cylinder wall 13 of the nozzle plug 8 protrudes with the dispensing cylinder 17 facing upward with the contents stored in the container body 2. Attached to the tube section 7. Since the opening of the protruding cylinder 7 is liquid-tightly closed by the seal lip 15 of the nozzle plug 8, the threaded portion of the screw 7 a of the protruding cylinder 7 and the screw 11 a of the nozzle plug 8 is threaded. Liquid leakage through the is prevented.

  In the state in which the cap 3 is mounted on the nozzle plug 8 of the mouth / neck portion 9, as shown in FIGS. 1 and 2 (a), the two long pieces 25a of the outer wall portion 25 of the cap 3 are formed into a cylindrical wall. It is along the part in which the recessed parts 18 and 19 in the outer peripheral surface of the part 10 were formed. In this state, the protrusion 28 is fitted in the recess 18 formed on the outer peripheral surface of the mouth-neck portion 9, and the protrusion 29 is fitted in the recess 19. Thereby, the cap 3 attached to the mouth / neck portion 9 is prevented from being unexpectedly removed. When the cap 3 is attached, the upper end portion of the outer cylindrical wall 11 in the mouth-and-neck portion 9 is sandwiched between the ring portion 26 and the long piece portion 25a and the short piece portion 25b in the outer wall portion 25. Yes. Thereby, in the state in which the cap 3 was mounted | worn, it is suppressed that the content leaks.

  In use, as shown in FIG. 5, the upper portion of the cap 3 is picked up with a finger, and the cap 3 is rotated counterclockwise (counterclockwise) about the axis in plan view, so that the projections 28 and 29 are The cap 3 can be removed by removing it from the recesses 18 and 19 and raising it as it is. In the container of this example, the protrusions 28 and the recesses 18, which are formed side by side in the circumferential direction in a front view, and the protrusions 29 and the recesses 19 are shifted in the vertical direction. Thereby, when the cap 3 is rotated counterclockwise and the projection 28 is detached from the recess 18, the projection 28 is not easily fitted into the recess 19 or the vertical groove 21. Therefore, the cap 3 can be removed smoothly by rotating the cap 3 counterclockwise.

  Thereafter, as shown in FIG. 4 (c), the cap 3 is inverted, the container body 2 is tilted so that the tip of the dispensing tube 17 of the nozzle plug 8 is directed downward, and the contents in the container body 2 are poured. It injects into the measurement cylinder part 22 through the extraction pipe | tube 17 from the exit 16b. The amount of the content injected into the measuring cylinder portion 22 of the cap 3 can be grasped by the scale portion 27. In the cap 3 when performing the weighing operation, since the vertical length of the short piece portion 25b of the outer wall portion 25 is short, the scale portion 27 is easily visible from between the long piece portions 25a and 25a, and is accommodated in the measuring tube portion 22. It is possible to accurately grasp the amount of the contents that have been processed.

  After using the contents after weighing, as shown in FIG. 6, the protrusions 28 and 29 provided on the long piece portion 25 a are aligned with the longitudinal groove portions 20 and 21 on the outer peripheral surface of the cylindrical wall portion 10, The measuring cylinder part 22 is inserted into the cylinder wall part 10 of the nozzle plug 8. At this time, the protrusions 28 and 29 are lowered and fitted into the recesses 18 and 19 along the longitudinal groove portions 20 and 21, respectively, so that the cap 3 is firmly attached.

  In the container of the present invention described above, the cap can be firmly attached to the mouth and neck by fitting the protrusion provided on the inner surface of the outer wall into the recess provided on the outer peripheral surface of the mouth and neck. Further, by rotating the cap and releasing the fitting between the protrusion and the recess, the cap can be easily removed without rotating the cap many times. Thus, the container of the present invention is easy to open and close the cap.

The container of the present invention is not limited to the container 1 described above.
For example, the container of the present invention may be, for example, the container 1A illustrated in FIG. Parts in FIG. 7 that are the same as those in FIG. The container 1A is the same as the container 1 except that the longitudinal groove portions 20A and 21A are provided instead of the longitudinal groove portions 20 and 21.
The vertical groove portion 20A includes a linear portion 30 that extends from the recess 18 to the upper end of the mouth-neck portion 9, and a release guide portion 31 that is formed to jump up from the recess 18 in the upper right direction when viewed from the front. The depth of the straight portion 30 of the vertical groove portion 20 </ b> A is shallower than the depth of the concave portion 18 as with the vertical groove portion 20.

The front-view shape of the release guiding portion 31 is gradually narrowed from the end on the recess 18 side toward the tip. Further, the depth of the release guiding portion 31 is gradually shallower from the end on the recess 18 side toward the tip.
Since the vertical groove portion 20 </ b> A includes the release guide portion 31, the step at the right edge portion of the recess 18 in the front view is smaller than in the case of the vertical groove portion 20 that does not include the release guide portion 31. Therefore, when the cap 3 is mounted and the projection 28 is fitted in the recess 18, when the cap 3 is rotated counterclockwise in plan view, the projection 28 is released from the recess 18 to the release guide portion 31. It becomes easy to come off to the side. Further, since the protrusion 28 moves along the release guide portion 31 formed so as to jump upward in a front view, a force to lift the cap 3 acts on the cap 3, so that the cap 3 can be removed more easily. Become.

Similar to the vertical groove 20A, the vertical groove 21A includes a linear portion 32 extending from the recess 19 to the upper end of the mouth-neck portion 9, and a release guiding portion 33 formed so as to jump upward from the recess 19 in the front view. .
The front view shape of the release guide portion 33 gradually decreases from the end on the concave portion 19 side toward the tip. In addition, the depth of the release guide portion 33 gradually decreases from the end on the concave portion 19 side toward the tip.

  Since the vertical groove portion 21A includes the release guide portion 33, the protruding portion 29 is easily detached from the concave portion 19 toward the release guide portion 33 as in the case of the vertical groove portion 20A. Further, since the protrusion 29 moves along the release guide portion 33 formed so as to jump upward in a front view, a force for lifting the cap 3 acts on the cap 3, so that the cap 3 can be removed more easily. Become.

  As described above, also in the container 1A, the protrusions 28 and 29 provided on the inner surface of the outer wall portion 25 are fitted into the recesses 18 and 19 provided on the outer peripheral surface of the mouth and neck portion 9, whereby the cap 3 is attached to the mouth and neck portion. 9 can be securely attached, and the operation of removing the cap 3 is also simple.

  The longitudinal groove part in the container of this invention is not limited to what is the same width | variety from a recessed part to the upper end of a mouth neck part. For example, as shown in FIG. 8, the container of the present invention extends from the recesses 18 and 19 to the upper end of the outer cylinder wall 11 that forms the mouth and neck, instead of the longitudinal grooves 20 and 21, and The container in which the longitudinal groove parts 34 and 35 which the diameter of the upper end side expanded toward upper direction may be formed. The same parts in FIG. 8 as in FIG. In the container, compared with a container having a vertical groove portion whose width of the upper end side portion is not expanded, when the cap is attached to the mouth and neck portion, the protrusion provided on the inner surface of the outer wall portion is connected to the vertical groove portion. Since the alignment is easy, it is easier to fit the protrusion into the recess.

When forming a vertical groove part as a groove part, the aspect of a vertical groove part is not limited to the aspect from which the depth is constant from the end by the side of a recessed part to the upper end of a mouth neck part. For example, as shown in FIG. 9, the longitudinal groove 20 may be a longitudinal groove 20 </ b> B in which the depth of the portion on the recess 18 side becomes shallower toward the recess 18. Similarly, in the vertical groove portion 21, the vertical groove portion 21 </ b> B in which the depth of the portion on the concave portion 19 side becomes shallower toward the concave portion 19 may be used. The same parts in FIG. 9 as in FIG. 2B are given the same reference numerals and description thereof is omitted.
In the container provided with the longitudinal groove portions 20B and 21B, since the level difference of the upper edge portion in the recess 18 is higher in front view than in the case of the container 1, the protrusion 28 fitted in the recess 18 is difficult to escape upward. Become. Similarly, since the level difference of the upper edge part in the recessed part 19 becomes high, the projection part 29 fitted in the recessed part 19 becomes difficult to escape upwards. Therefore, in the container, it is easier to prevent the attached cap 3 from being unexpectedly pulled out than the container 1.

In the container of the present invention, the number of protrusions in the container 1 is a total of four pairs consisting of two pairs, but is not limited thereto, and may be three or less, or may be five or more. .
What is necessary is just to determine the number of the recessed parts provided in the outer peripheral surface of a mouth neck part according to the number of the projection parts provided in an outer wall part. In this invention, the number of the recessed parts provided in the outer peripheral surface of a mouth neck part may be larger than the number of the projection parts provided in the outer wall part of a cap.

  In the container of this invention, when forming a groove part in the outer peripheral surface of a mouth neck part, you may form the horizontal groove part extended in the circumferential direction of a mouth neck part as a groove part. Specifically, as shown in FIG. 10, a lateral groove portion 38 is formed on the outer peripheral surface of the mouth / neck portion 9 over the entire circumference in the circumferential direction, and a concave portion 39 having a depth deeper than the lateral groove portion 38 in the lateral groove portion 38. It may be a container in which is formed. Parts in FIG. 10 that are the same as those in FIG. In the container, when the cap is placed on the mouth and neck portion 9 from above, the protrusion portion 40 fits into the lateral groove portion 38 regardless of the position of the protrusion portion 40 provided on the inner surface of the outer wall portion 25. Then, by rotating the cap 3 in this state, the protruding portion 40 can be guided and fitted into the concave portion 39 by the lateral groove portion 38. As described above, in the container, since it is not necessary to align the protrusion when the cap is mounted, the cap can be mounted more easily.

The container of the present invention may be a container in which no groove is formed on the outer peripheral surface of the mouth and neck.
In the container of the present invention, the number of the long piece portions and the short piece portions in the outer wall portion is not limited to two, for example, a container in which three long piece portions and three short piece portions are provided at equal intervals, respectively. Alternatively, a container in which four long piece portions and four short piece portions are provided at equal intervals may be used.
In the container of the present invention, when the outer wall portion of the cap includes a long piece portion, the shape of the long piece portion when viewed from the front is not limited to a tongue shape, and may be, for example, a rectangular shape or a semicircular shape. .

The cap in the container of the present invention is not limited to one having an outer wall portion having a long piece portion and a short piece portion.
