Description

  The present invention relates to a container with a sealing function so that it can be determined whether or not it has been opened.

  Products shipped with containers filled with beverages and foods are basically not opened until they reach the consumer's hands, maintaining the quality of the product as it is, and preventing the entry of foreign substances. It is necessary to keep food safe.

  For this reason, products with containers filled with beverages or foods should be sealed by applying a heat-shrinkable film to the container body and lid, and unsealed unless the heat-shrinkable film is removed. However, once opened, the heat-shrinkable film is removed, so that it can be immediately found out.

  However, in order to shrink the heat-shrinkable film, it is necessary to apply a certain amount of heat, so that it is difficult to apply it to those in which the beverage or food to be filled is altered by heat.

  On the other hand, as an example not using a heat shrink film, in a container such as a so-called PET bottle as shown in FIG. In this way, the cap 21 is screwed into the mouth portion 24 of the bottle main body 20, and the rib 25 formed on the inner periphery of the hem 23 of the cap 21 when screwed is formed in the annular step formed in the mouth portion 24 of the bottle main body 20. There are some which are configured to be caught by the portion 26.

  However, although it is suitable for a container having a small diameter such as a PET bottle, a container having a large diameter increases the amount of resin at the cap skirt portion that is separated and becomes unnecessary after opening, and is not efficient. Further, as the diameter of the cap increases, a large couple tends to be required to separate the cap body and the skirt with the annular cutout.

  On the other hand, Patent Documents 1 and 2 provide an excisable portion that can be separated from a part of the cap, and the separation of the excised portion enables the lid to be opened and clearly shows that the lid has been opened. A container is described.

JP 2003-054618 A Japanese Patent Laid-Open No. 2001-341761

However, as shown in FIG. 4 of Patent Document 1, there is no wrinkle or the like below the threaded portion of the container, and foreign matter such as dust may be mixed through the gaps in the screw.
Furthermore, the pull ring of Patent Document 1 has a structure in which a hole is provided inside and a protrusion is fitted therein. However, since there is only one location, depending on the case, a large force is required to remove the fit, or conversely, if the fit is weak, the fit may be disengaged during transportation. In some cases, the excision may be cut off.

  Further, in Patent Document 2, a pull ring is not used and the problem of disengagement is unlikely to occur. However, since the excision part is provided at the lower end of the side peripheral part of the lid, the lower end surface of the excision part is a lid. There is no connection with the side peripheral part, the connection part between the excision part and the lid is reduced, and there is a possibility that the connection between the two becomes weak. Further, a gripping part is provided so as to protrude from the side peripheral part of the lid. For these reasons, when force is applied to the gripping part due to vibration during transportation, the excision part may be easily separated and fall off.

  Accordingly, an object of the present invention is to suppress the possibility of foreign matter being mixed and to prevent a member that clearly indicates the presence or absence of opening from falling off during transportation.

  In order to solve the above-described problems, the present invention provides a container main body comprising a container storage portion for storing contents and a container mouth portion having a male screw formed on the outer peripheral surface, and a female screw to be screwed into the container mouth portion. An annular flange is formed on the outer peripheral surface of the container mouth portion closer to the container housing portion than the male screw, and between the end portion of the male screw and the flange portion. A container-side protrusion is provided, a lid-side protrusion that engages with the container-side protrusion is provided on an inner peripheral surface of the lid-side periphery, does not include a lower end edge of the lid-side periphery, and the lid A part of the lid side peripheral part including the side protrusion part is provided as a detachable part so that the outer peripheral diameter of the collar part is smaller than the inner peripheral diameter of the lid, and the inner periphery of the protruding end of the lid side protrusion part Larger than the diameter, and at one end of the separation portion arranged in the circumferential direction of the lid side peripheral portion, this separation portion is A holding part for connecting the gripping part for separation and detachably holding the gripping part at the edge part of the lid side peripheral part facing the side edge part between both end parts of the separation part is separated from each other. At least a pair is provided so as to be opposed to each other through the portion, and the gripping portion is bent so as to cover at least a part of the outer peripheral surface of the separation portion, and the state where the gripping portion is bent is held by the holding portion. In the grip part, a part of the part on the tip side from the part held by the holding part overlaps with a part of the outer peripheral surface of the lid side peripheral part other than the separation part, and the lid side protrusion part is The container-side protruding portion can get over in the screwing direction. On the other hand, after screwing, it is difficult to release the screwing by engaging in the screwing releasing direction. The lid-side protrusion is the container-side protrusion. Engagement is released, it is obtained by a configuration that can open the lid in engagement releasing direction.

Since the invention concerning the container with a sealing function described above is provided with an annular flange having a specific size, it is possible to suppress the entry of foreign matter from the threaded portion of the container.
Moreover, since the separation part is provided at a position not including the lower end edge of the lid side peripheral part, the entire circumference of the separation part faces the side peripheral part of the lid, and the connection between the separation part and the cover is sufficiently and uniform. Therefore, it is possible to prevent an unscheduled external force from applying an excessive force to some of the connecting portions and unscheduling the separating portion.
Furthermore, since the gripping portion of the separating portion is held by at least a pair of holding portions in a bent state, the gripping portion can be prevented from protruding and troubles coming off from the holding portion of the gripping portion can be reduced. Therefore, it is possible to prevent an unscheduled external force from being applied to the gripping portion and the detachment portion to be unscheduled unscheduled by the external force.
Furthermore, the gripping part is bent and held so as to cover a part of the separation part, and a part on the tip side of the gripping part overlaps a part of the outer peripheral surface of the lid side peripheral part other than the separation part. Even if an unscheduled external force is applied to the gripping part, it is possible to prevent all the external forces from being applied to the separating part, and to prevent the separating part from being unscheduled.

Embodiments of the present invention will be described with reference to the drawings.
(Container with sealing function)
As shown in FIGS. 1 and 2, a container 11 with a sealing function according to the present invention includes a container main body 12 including a container storage portion 12a for storing contents and a container mouth portion 12b in which a male screw 12c is formed on the outer peripheral surface. And the container which consists of the lid | cover 13 in which the internal thread (13b of FIG. 3) screwed together with the external thread 12c of this container opening part 12b was formed in the internal peripheral surface of the lid side peripheral part 13a.

(Isobe)
As shown in FIG. 2, an annular flange 12d is formed on the outer peripheral surface of the container mouth portion 12b on the container storage portion 12a side from the male screw 12c. The lid side peripheral portion 13a and the container mouth portion 12b are screwed together by the male screw 12c and the female screw 13b, but it does not necessarily prevent foreign matters such as dust from entering the inside of the container along both screws. By providing the flange portion 12d, it is possible to prevent the foreign matter from entering from between the lid side peripheral portion 13a and the container mouth portion 12b.

(Container side protrusion, lid side protrusion)
In addition, a container-side protrusion 12e is provided between the terminal portion of the male screw 12c and the flange 12d, as shown in FIGS. In particular, when the container-side protruding portion 12e is provided in a state of being continuous with the end portion of the male screw 12c and the flange portion 12d, the effect of the present invention can be further exhibited.
And as shown in FIG.3 (b), the cover side protrusion part 13c engaged with the said container side protrusion part 12e is provided in the internal peripheral surface of the cover side peripheral part 13a.

As shown in FIGS. 2 to 4, each of the container side protrusion 12 e and the lid side protrusion 13 c forms a wedge-shaped protrusion having an inclined surface on one side. And when it is going to close the lid | cover 13 to the container opening part 12b of the container main body 12, both inclination is carried out so that the lid side protrusion part 13c can get over in the screwing direction with respect to the container side protrusion part 12e. Arranged so that the faces face each other.
Then, after the lid 13 is screwed into the container mouth portion 12b of the container main body 12, the wedge-shaped top portions of the wedge-shaped top portions are opposed to each other in the screwing release direction. .

(Separation part)
By the way, in the lid side peripheral portion 13a, a portion of the lid side peripheral portion 13a (detaching portion 13d) including the lid side protruding portion 13c is cut off at a position not including the lower end edge of the lid side peripheral portion 13a. Provided possible.

Since the separation portion 13d is provided at a position not including the lower end edge of the lid-side peripheral portion 13a, the separation portion 13d is surrounded by the lid-side peripheral portion 13a.
Between the edge of the lid-side peripheral portion 13a (hereinafter, simply referred to as “the edge of the lid-side peripheral portion 13a”) facing the separation portion 13d and the separation portion 13d, a plurality of connecting members 13h are used. Connected. In FIG. 3 (a), the separation part 13d and the edge of the lid side peripheral part 13a are connected at five points. This connection is a point connection if the force required for the separation is within an appropriate range. Or the connection by the connection material which has a width | variety may be sufficient. In addition, the number of connections is appropriately selected so that the force required for disconnection falls within an appropriate range.

  By separating the separation portion 13d, the lid-side protrusion 13c can be disengaged from the container-side protrusion 12e. Thereby, the lid 13 can be opened in the screwing release direction.

  By the way, this separation part 13d is not provided in the lower end edge part of the lid side peripheral part 13a. This is because, when this separating portion 13d is provided at the lower end edge portion of the lid side peripheral portion 13a, the edge portion of the separating portion 13d located at the extended portion of the lower end edge of the lid side peripheral portion 13a is the same as the lid side peripheral portion 13a. No connection will be formed. In this case, when an unscheduled external force is applied to the separating part 13d, a large external force is applied to the connecting part near the edge of the separating part 13d without the connecting part, and the separating part 13d is disconnected unexpectedly. Because there is a fear.

(Diameter of buttocks)
The outer peripheral diameter of the flange portion 12d of the container body 12 is smaller than the inner peripheral diameter of the lid 13 (lid side peripheral portion 13a) and larger than the inner peripheral diameter of the protruding end of the lid side protruding portion 13c. If the outer peripheral diameter of the collar part 12d is larger than the inner peripheral diameter of the lid 13 (lid side circumferential part 13a), the lid 13 will hit the collar part 12d and will not close any further. In this case, since the separation part 13d is in a position not including the lower end edge of the lid side peripheral part 13a, the lid side projection part 13c disposed inside the separation part 13d is screwed to the position of the container side projection part 12e. It becomes difficult to properly cover the lid.
On the other hand, if the outer peripheral diameter of the flange portion 12d is smaller than the inner peripheral diameter of the protruding end of the lid-side protrusion portion 13c, the lid-side protrusion portion 13c can get over the flange portion 12d when the lid is closed, and the separation portion 13d. There is a possibility that the lid can be opened without detaching.

(Gripping part)
As shown in FIG. 3, a grip portion 13e for separating the separation portion 13d from the lid side peripheral portion 13a is connected to the separation portion 13d. Specifically, the gripping portion 13e is connected to one end of both ends of the separating portion 13d arranged in the circumferential direction of the lid-side peripheral portion 13a. By disposing the gripping part 13e on one of both ends of the separation part 13d arranged in the circumferential direction of the lid side peripheral part 13a, the tip part from the root part of the gripping part 13e connected to the separation part 13d This can be the circumferential direction of the lid side peripheral portion 13a, and the height of the lid can be suppressed.

(Holding part)
At the edge of the surrounding lid side peripheral portion 13a facing the separation portion 13d, specifically, at the edge of the lid side circumferential portion facing the side edge portion between both end portions of the separation portion 13d, FIG. As shown in FIG. 3, at least a pair of holding parts 13f that detachably hold the gripping part 13e are provided so as to face each other through a separating part 13d. A protrusion 13g is formed on the holding portion 13f.
Since at least a pair of holding portions 13f are provided, the gripping portion 13e is held by at least two protrusions 13g of at least two holding portions 13f. For this reason, by adjusting the size of the protrusion 13g and the number of the gripping portions 13e, it is possible to adjust the degree of force required for the gripping portion 13e to be detached from the holding portion 13f. Therefore, it is easy to intentionally remove the gripping part 13e from the holding part 13f and prevent the gripping part 13e from being unexpectedly detached from the holding part 13f even when an unexpected external force is applied during transportation or the like. it can.

(Grip shape)
A part of the grip part 13e on the tip side of the part held by the holding part 13f overlaps a part of the outer peripheral surface of the lid side peripheral part 13a other than the separating part 13d. For this reason, when an unexpected external force is applied during transportation or the like, a part of the external force is received by the outer peripheral surface of the lid side peripheral portion 13a, and the gripping portion 13e is unexpectedly detached from the holding portion 13f. Can be prevented.

  Of the gripping part 13e, the shape of a part of the tip side from the part held by the holding part 13f is such that the gripping part 13e is removed from the holding part 13f and the separating part 13d is connected to the lid side peripheral part 13a. The shape is not particularly limited as long as it is a preferable shape for performing the operation of separating from the substrate. As such an example, there is a pull-ring handle as shown in FIG.

(Sealing method and opening method)
Next, a sealing method using the container 11 with a sealing function according to the present invention will be described with reference to FIGS.
First, as shown in FIG. 2, with the lid 13 open, the contents are put into the container housing portion 12a of the container body 12, and the lid 13 is screwed along the male screw 12c and the female screw 13b as shown in FIG. And close. When closing the lid 13, and the inclined portion of the inclined portion of the container-side protrusion portion 12e and the cover-side projections 13c raises ride together, get over each other. After the lid 13 is closed, as shown in FIG. 5 (b), the container-side protruding portion 12e and the lid-side protruding portion 13c are engaged with each other because the flat portions of the tops of each other face each other. It is difficult to open the lid 13 in the screwing direction.
In addition, at this time, as shown in FIG.5 (c), the lower end edge of the lid side peripheral part 13a is located below the collar part 12d.

  Then, as shown in FIG. 5 (a), the gripping portion 13e is bent so as to cover at least a part of the outer peripheral surface of the separating portion 13d, and the gripped portion 13e is bent into a pair of holding portions 13f. It is hooked on 13 g of the protrusions and held. Thereby, a container can be sealed.

Next, the opening method of a container is demonstrated using FIG.
As shown in FIG. 6A, the gripping portion 13e of the sealed lid 13 is raised and the holding portion 13f is released (FIG. 6B). Next, the connecting member 13h is cut by pulling the gripping part 13e forward, and the separating part 13d is separated from the lid-side peripheral part 13a (FIG. 6C). By completely separating the separating portion 13d, the container side protruding portion 12e is released from the lid side protruding portion 13c, and the lid can be opened in the screwing release direction.

  By separating the separation part 13d, as shown in FIG. 6D, the part where the separation part 13d was present from the lid 13 becomes blank, and it is clearly indicated that the container has been opened.
