Description

  The present invention relates to a bottle container having an opening prevention mechanism.

  Conventionally, in order to show that the bottle container is not kept unused or illegally opened, it is widely known to wrap the bottle container with a heat-shrink film, and it is still widely used. However, a bottle container packaged with a heat-shrinkable film requires a heat-shrinkable film other than a cap for its packaging, and it takes time and effort for the packaging. There are many problems such as troublesome and troublesome film removal at the start of use.

  In order to solve such a problem, a container to which a cap with a virgin mechanism is attached is known (see Patent Documents 1 to 4). These caps with a virgin mechanism cover the knob part on the opposite side of the hinge of the cover body with a virgin cover formed integrally with the cap body and the like, making it difficult to grip the knob part and trying to prevent unauthorized opening of the cover There are many things. However, although these conventional techniques make it difficult to grip the knob portion, it cannot always be said to completely prevent unauthorized opening of the lid by a nearby instrument. In addition, a special mold is required to manufacture a cap body with a virgin cover, which is expensive, and it is difficult to form a good-looking shape after cutting and removing the virgin cover. There is also a problem that the later unappealing part is close to the knob part, and the unappealing appearance is emphasized.

  In order to solve such problems of the prior art, the present inventor is considering covering the entire upper surface of the hinged lid with a virgin cover in order to further prevent unauthorized opening. In the process of assembling the container, a strong force is applied to the virgin cover when attaching the cap to the container, so the virgin cover needs to be strong. The problem of becoming very large was recognized.

  The present invention is a cap with a virgin cover that is attached to the neck portion of a container body, and a bottle container in which the cap is put on the container body. The cap with the virgin cover is attached to the neck portion of the container body, and the crown portion of the virgin cover is attached without being cut and removed, so that the container with the cap attached is in an unused state. It clearly shows that it has not been used illegally. At the start of use, the lid can be opened by cutting and removing the crowned portion, so the contents can be poured out from the spout by opening the lid.

The cap with a virgin cover is an inner cap that has a spout for contents and is attached to the neck of the container body in a state that prevents it from being removed, and an outer cap that is attached to the inner cap, and can be opened and closed by a hinge portion. An outer cap including a supported lid, a closing member provided on the lid and closing the spout when the lid is closed, and a virgin cover. The virgin cover is in contact with the lower end surface of the inner cap, and when the inner cap is attached to the neck of the container body in a retaining state, the retaining member is in a retaining state, and the retaining member is easily attached to the retaining body. And a crowned portion that is held by being coupled via a cut and coupled portion and covers the outer peripheral surface of the outer cap and the outer peripheral surface of the upper surface of the lid opposite to the hinge portion.
The crowned portion covers the outer peripheral surface of the outer cap and the outer peripheral surface of the lid body opposite to the hinge portion, thereby preventing unauthorized opening of the lid body and unauthorized removal of the outer cap including the lid body. To prevent. Further, due to such a structure of the virgin cover, the virgin cover, the inner cap and the outer cap are combined together, and the handling thereof becomes easy.
The holding body comes into contact with the lower end surface of the inner cap, so that when the inner cap is attached to the neck of the container body in a retaining state, the retaining body is in a retaining state like the inner cap, and the easily cut coupling portion The crown portion connected via the cap is not removed unless the easily cut connecting portion is cut, and the lid body is maintained in the closed state.
In the present invention, the “prevention state” means a state where it cannot be removed at least easily by a normal person's bare hands.

  It is desirable that a rotation stop portion is formed between the inner cap and the outer cap and between the inner cap and the holding body. With this configuration, the alignment between the virgin cover and the outer cap can be facilitated, and variations among caps with a virgin cover can be reduced.

  The range of the outer cap outer peripheral surface and the lid upper surface outer peripheral portion covered by the crown portion of the virgin cover is preferably more than 180 degrees and not more than 230 degrees on the side opposite to the hinge section, more preferably 190 to 210 degrees. . By setting such an angle, it is possible to more reliably prevent unauthorized opening compared to the case where only the knob portion of the lid is covered, and the interval between the circumferential ends of the crown portion is the outer cap. Since the undercut is smaller than the outer diameter, the combination cap can be prevented from being detached from both circumferential ends of the crowned portion, and the integration of the virgin cover and the combination cap is more sure.

The easy-cut coupling part that joins the holding body and the crown part is provided with a plurality of twist ribs spaced apart from each other in terms of ease of cutting and appearance after cutting and removal of the crown part. It is desirable to be a thing.
If the holding body is in a retaining state, like the inner cap, when the inner cap is attached to the neck of the container body in a retaining state by contacting the lower end surface of the inner cap. Any shape and structure may be used. If the holding body is a holding ring that comes into contact with the lower end surface of the inner cap, the ring-shaped structure can prevent the holding body from coming off.

  It is preferable that the crowned portion has a knob portion on the top thereof so that the cutting and removal can be easily performed. The position of the knob portion can be appropriately changed in design according to the position and structure of the easy-cut coupling portion.

  The cap with a virgin cover of the present invention is attached to the bottle container body after the contents are filled. At this time, it is desirable that a rotation stopper is formed between the inner cap and the bottle container main body and / or between the holding ring and the bottle container main body. If the structure of the container body and the printed pattern on the surface are not rotationally symmetric, the anti-rotation part is formed so that the hinge part and the virgin cover are in accordance with the structure of the container body and the surface pattern. It is possible to set a desired position and direction. Any structure may be used for the rotation stopper, but generally one or a plurality of recesses formed on one member and the recess formed on the other member are fitted. It can consist of one or a plurality of protrusions.

  The material of the cap with the virgin cover and the container body is not particularly limited, but generally, synthetic resin, metal, glass, a composite material thereof, a composite body, or the like can be used. In addition, various physical properties such as transparency, opaqueness, partial transparency, heat resistance, gas impermeability, and the like can be adopted depending on the contents and applications. Since the cap with the virgin cover is integrated, if it is made of the same kind of synthetic resin, it is desirable in terms of recycling and can be easily manufactured by a molding method such as injection molding. The synthetic resin to be used is not limited, and examples thereof include olefin resins such as polypropylene and polyethylene.

  The contents filled in the container body are not limited, but are generally liquids, granules, powders, solid-liquid mixtures, frozen products, etc., and cosmetics such as facial cleansing powders, detergents, various drugs, beverages And food.

Below, each component is further demonstrated.
[1. overall structure〕
The cap with a virgin cover of the present invention is attached to the neck of the container body. The cap with a virgin cover is an inner cap that is provided with a spout for contents and is attached to the neck of the container body in a state of being prevented from coming off, and an outer cap that is attached to the inner cap, and can be opened and closed by a hinge portion. A lid that is supported, an outer cap that is provided on the lid and includes a closing member that closes the spout when the lid is closed, and a virgin cover that includes a holder and a crowned portion. The In order to form the cap with the virgin cover, first, the outer cap is pressed and attached to the upper portion of the inner cap to form a combination cap, and then the portion opposite to the hinge portion of the combination cap is first By moving the combination cap from the side of the virgin cover toward the center portion of the inner peripheral surface of the crown portion, the lower end surface of the inner cap is brought into contact with the upper surface of the holding body, and the crown portion is opposite to the hinge portion. The outer cap outer peripheral surface on the side and the lid upper surface outer peripheral portion are combined so as to be crowned.

[2. Inner cap)
The inner cap has a spout at the top, and is attached to the neck of the container body in a retaining state. Desirably, it comprises a concentric outer cylinder part and an inner cylinder part, and the neck part of the container body is sandwiched between them. When the diameter of the spout is large, a spout cylinder that forms the spout can be formed continuously with the inner cylinder. The inner cap is preferably attached to the container body so as not to rotate. The connection structure with the container main body is a structure defined mutually with the container main body, but both the vertical retaining function and the anti-rotation function can be realized by combining, for example, dotted irregularities. . Moreover, it can be set as a retaining state by combining a ring-shaped convex part and a concave part, and rotation in the circumferential direction can be restricted by combining the convex part and the concave part in the vertical direction. One or more ribs are provided below the neck of the container body, and one or more ribs are provided on the lower inner peripheral surface of the inner cap. It is also possible to prevent rotation. The lower end surface of the inner cap is desirably provided with a slope that is inclined downward from the inner periphery to the outer periphery so that a holding body such as a holding ring that contacts the surface is prevented from coming off.

[3. (Outer cap)
The outer cap is attached to the upper part of the inner cap, preferably with a detent. The outer cap includes an outer cap body and a lid that is supported by a hinge portion so as to be opened and closed. On the inner surface of the cylindrical portion of the outer cap main body, a concave portion such as an annular concave portion that engages with a retaining convex portion provided on the outer surface of the outer cylindrical portion of the inner cap, and preferably engages with a locking portion of the inner cap. A rotation stopper such as a vertical rib is formed. When the cap with virgin cover is attached to the neck of the container body, the outer cap is crowned by the crown of the virgin cover and cannot be tampered with. Although it is not necessary to have a “prevention state” similar to the attachment of the cap, it does not exclude the same “prevention state”.
The lid includes a closing member that closes the spout of the inner cap when the lid is closed. The closing member is preferably a plug that protrudes substantially perpendicularly from the ceiling surface of the lid and closes the spout by contacting the inner surface of the inner cylinder of the inner cap when the lid is closed. A closing member that presses against the tip and closes the tip of the spout can also be used. For example, the plug body may have a cylindrical shape whose outer peripheral surface is in contact with the inner surface of the extraction tube portion and closes the outlet.
The hinge portion that connects the outer cap body and the lid body is composed of two hinges and a posture holding piece that is formed between the hinges and holds the lid body in an open position or a closed position in the closed position. However, it is possible to make various design changes such as omitting the posture holding piece to form one hinge.
A lid for opening / closing the lid can be formed on the lid on the side opposite to the hinge.
The contact portion between the outer cap main body and the lid opposite to the hinge portion of the outer cap includes a locking portion that engages with each other so that the lid does not open carelessly when the lid is closed. An engaging part can be formed.

[4. Virgin cover)
The virgin cover is in contact with the lower end surface of the inner cap, and when the inner cap is attached to the neck of the container body in a retaining state, the retaining member is in a retaining state, and is easily coupled to the retaining body. And a crowned portion that covers the outer peripheral surface of the outer cap and the outer peripheral surface of the lid upper surface opposite to the hinge portion.
In order to prevent the holding body from being detached when the inner cap is attached to the neck of the container main body, for example, a ring-shaped holding ring that contacts the entire lower end surface of the inner cap. And so on. In addition, the holding body is pressed and fixed between the lower end surface of the inner cap and the upper surface of the shoulder portion of the container main body, or the lower end surface of the inner cap is made an undercut structure so that the holding body is prevented from coming off. You can also In that case, the holding body does not need to have a ring shape, and may have various shapes and structures such as a semicircular shape or a partially cut ring shape. Furthermore, the holding body can have a portion that protrudes somewhat from the range of the lower end of the inner cap and covers the outer periphery of the lower end of the inner cap (outer periphery of the buttock) and the outer periphery of the outer cap as long as the combination with the combination cap is not hindered. . With such a structure, the virgin cover, the inner cap, and the outer cap can be more reliably integrated.
The range of the outer cap outer surface on the opposite side of the hinge portion to be crowned by the crowned portion and the outer peripheral portion of the lid upper surface is determined in consideration of the elastic deformability of the material, but in general, it is opposite to the hinge portion. More than 180 degrees on the side and 230 degrees or less, preferably 190 to 210 degrees. By setting such an angle, it is possible to more reliably prevent unauthorized opening compared to the case where only the knob portion of the lid is covered, and the distance between both ends in the circumferential direction of the crown portion is a combination cap. Since the undercut is smaller than the outer diameter, it is possible to prevent the combination cap from being detached from both circumferential ends of the crowned portion. If it exceeds 230 degrees, it becomes difficult to combine the virgin cover and the combination cap, and it becomes difficult to remove the crowned portion from the combination cap and remove it when the bottle container starts to be used.
The top wall of the crowned portion is not covered with the center of the upper surface of the lid that is pressed when the cap with the virgin cover is attached to the neck of the container body, and the outer circumference of the lid upper surface opposite to the hinge portion is covered. Any shape and structure may be used as long as it can be crowned. For example, it is most simple and desirable in terms of appearance and design that the central part of the top surface of the crown part top wall is concentric with the outer periphery of the top of the cover, but this is not a limitation. Or may be configured by a plurality of straight lines or waveforms.
The peripheral wall part of the crowned part may be formed so as to faithfully follow the outer peripheral surface shape of the combination cap including the knob part, etc., but within a range that can ensure prevention of unauthorized opening of the lid and unauthorized removal of the outer cap It is not necessary to faithfully trace the shape, and an appropriate shape can be obtained. In addition, the portion of the peripheral wall portion that is not so much involved in preventing the combination cap from being removed from both ends in the circumferential direction of the crowned portion, preventing unauthorized opening of the lid, and preventing unauthorized removal of the outer cap, reduces the material savings. From the viewpoint, it may be one or a plurality of openings or thin portions.
The easy-to-cut coupling part that joins the holding body and the crowned part is configured so that the crowned part can be easily cut and removed without using a special instrument etc. at the start of use of the bottle container attached with a cap with a virgin cover However, it is desirable that the appearance after cutting and removal is not deteriorated and is good. As such an easy-cut coupling portion, for example, a plurality of ribs provided at intervals along the boundary between the holding body and the crowned portion (that is, a small cross section in a direction perpendicular to the boundary). It can be composed of short ribs that extend. The ribs can be easily cut and can be formed with notches taking into account large traces of cutting. The arrangement of the ribs at the plurality of locations is designed in consideration of the removal method of the crowned portion, but two locations of 45 degrees on both sides from one location on the opposite side of the hinge portion, and two locations of 90 degrees on both sides, When the grip part formed at the upper part of the crown part is gripped and moved in the opposite direction to the hinge part, stress concentrates on the two ribs on the side close to the hinge part. Next, two places slightly apart from the hinge part are cut in the same manner, and finally, the one rib rib on the opposite side of the hinge part is cut in the same way. It does not look bad and is kept relatively good. The easy-cut coupling portion of the present invention is not limited to such a structure, and various design changes such as a continuous or intermittent thin-walled portion can be made within a range that can be easily cut.

[5. (Bottle container body)
Various shapes and structures such as rotational symmetry and rotational asymmetry can be adopted for the container body. A cylindrical neck portion is provided on the upper portion, and a shoulder portion that is inclined horizontally or downward can be formed immediately below the neck portion. The cylindrical neck portion is generally cylindrical, but part or all of the cylindrical neck portion may be a cylindrical shape having various cross-sectional shapes in addition to a rectangular tube such as a square tube. In such a case, the inner cap, the outer cap, and the virgin cover are also formed in a shape / structure corresponding to the shape / structure of the cylindrical portion. One or a plurality of vertical ribs for preventing rotation with respect to the inner cap and / or the holding body can be formed at the proximal end of the neck. When providing a plurality, it is desirable to provide them at equal intervals.
An annular protrusion is formed on the outer surface of the cylindrical portion forming the neck. The annular protrusion may be continuous in a ring shape, or may be provided with a dot or line shape intermittently. From the viewpoint of ease of molding, an integral ring shape is preferable, and in the case of a dot shape or a line shape, 2 to 4 pieces are appropriate. The annular protrusion is formed so as to be positioned above the locking protrusion provided on the inner cap so as to be prevented from coming off when the cap with the virgin cover is attached. The structure for mounting in the retaining state is not limited to such a contact structure between the protrusion and the protrusion, and various design changes such as fitting of the protrusion and the recess can be made.
It is desirable that the annular protrusion be provided above the vertical rib. It is desirable that the upper surface of the vertical rib be a tapered surface inclined downward so that the engagement with the inner cap and / or the rotation preventing portion of the holding body is facilitated.

A slope is formed on the lower surface of the holding ring 61 so as to incline downward from the inner periphery to the outer periphery in accordance with the inclination of the upper surface of the shoulder portion 22 of the container body 2.

  The easy-cut coupling part 63 is configured so that the crowned part 62 can be easily cut and removed at the start of use of the bottle container 1 to which the cap 3 with a virgin cover is attached without using a special instrument or the like. There are provided multiple ribs 63 (that is, short ribs extending in a direction perpendicular to the boundary with a small cross section) provided at intervals along the boundary between the ring 61 and the crowned portion 62. . The arrangement of the plurality of ribs 63 is designed in consideration of the removal method of the crowned portion 62, but as shown by the arrow in FIG. In the embodiment in which 62 is removed, two locations of 45 degrees on both sides from one location on the opposite side of the hinge portion 53 and two locations of 90 degrees on both sides are provided (see FIG. 1A). When the knob portion 66 is moved to the left as shown by the arrow in FIG. 1B with such an arrangement of the turning ribs 63, stress is first concentrated on the two turning ribs 63 on the side close to the hinge portion 53. Therefore, it is cut without impairing the appearance due to a large deformation, and then two places slightly separated from the hinge part 53 are cut in the same manner. Finally, the one rib rib 63 on the opposite side of the hinge part 53 is similarly cut. Since it is cut, the appearance after removing the cut is not deteriorated and is kept relatively good.

<Cap 3 with virgin cover>
The cap 3 with a virgin cover shown in the plan view of FIG. 6A, the side cross-sectional view of FIG. 6B, and the side view of FIG. 6C is attached to the virgin cover 6 with the arrow in FIG. It is formed by combining the combination caps 4 and 5 from the direction. At that time, the upper surface of the holding ring 61 is in contact with the lower end surface of the inner cap 4, and the anti-rotation projection 44 at the lower end of the inner cap 4 is engaged with the anti-rotation recess 67 of the holding ring 61 and is prevented from rotating. 62 covers the outer peripheral surface of the outer cap 5 on the opposite side of the hinge portion 53 and the outer peripheral portion of the lid upper surface 52a, thereby maintaining the closed state of the lid 52, and the virgin cover 6 includes the combination caps 4 and 5 Combined with.

  The range of the outer peripheral surface of the outer cap 5 and the outer surface of the lid upper surface 52a that the crowned portion 62 is crowned is set to 200 degrees in this embodiment, and the interval between both ends in the circumferential direction of the crowned portion 62 is the outer cap. Since the undercut is smaller than the outer diameter of 5, the separation of the combination caps 4 and 5 from both circumferential ends of the crowned portion 62 can be prevented (see FIGS. 7C and 7D). Moreover, because of such a structure, the virgin cover 6 and the combination caps 4 and 5 are combined together, so that they can be handled easily and can be attached to the container body 2 thereafter.

  The crowned portion 62 does not crown the outer peripheral surface of the outer cap 5 or the entire upper surface 52a of the lid, but covers the crown slightly beyond a half circumference, and the upper surface 52a of the lid 52 has a half circumference. Since the outer circumferential portion slightly exceeding is crowned, the lid upper surface 52a is more reliably prevented while preventing the unauthorized opening of the lid 52 and the unauthorized removal of the outer cap 5 than when only the knob portion 57 is crowned. Compared with the case where the entire surface of the crown is covered, the material necessary for the crowned portion 62 can be greatly reduced. Furthermore, when attaching the cap 3 with the virgin cover to the neck portion 21 of the container body 2, the lid upper surface 52a not covered with the crowned portion 62 can be pressed, so the crowned portion covering the entire lid upper surface 52a is pressed. Compared to the case, the crowned portion 62 does not need much strength, and the material can be saved also from the surface.

<Bottle container 1 with cap 3 with virgin cover>
The bottle container 1 to which the cap 3 with virgin cover shown in FIG. 1 (A) is attached is obtained by attaching the cap 3 with virgin cover to the neck portion 21 of the container body 2 as shown by the arrow in FIG. It is formed.
