Description

  The present invention relates to a container with an opening means. More specifically, the present invention relates to a container attached with an opening and spout member that opens a sealing film of a container body filled with the contents and constitutes a spout for the contents.

  Conventionally, many containers have been proposed in which the spout is kept sealed when not in use and the sealing film provided at the spout is opened at the start of use. Also known is a cap structure with an unauthorized opening prevention mechanism (opening prevention member) so that it cannot be opened carelessly in an unused state.

  In Patent Document 1 (Patent No. 3024089) previously proposed by the present applicant, an opening stopper (annular band) is provided at the lower end of the outer peripheral wall, and an inner plug in which a sealing film (seal) is formed is provided. Sealed and fixed to the neck of the container body filled with the contents, and on the bottle container covered with an outer cap on which a guide cylinder for sealing film opening is formed, the opening prevention member is the outer periphery of the inner plug After separating from the lower end, it is described that the outer cap is pressed from above to lower the outer cap, the sealing film is opened by the guide tube formed on the outer cap, and the outer cap is fixed to the container neck. Yes. In this prior art, there is no need to remove the outer cap at the time of opening operation, there is no danger of contamination and finger contamination, and there are many advantages such that the container can be kept hermetically sealed after the start of use. However, there is also a problem that a relatively large force is required for pressing the outer cap at the time of opening, which is undesirably aesthetically left after the opening preventing member is cut off.

  Similarly, in Patent Document 2 (Patent No. 4045277) previously proposed by the present applicant, a bottle of a type in which an unsealing prevention member is provided separately from a cap, and the unsealing prevention member is removed and opened to start use. In the container, after the contents are filled from the neck of the container body, the cap is attached to the neck of the container body in a sealed state, and the cap is re-screwed to the shoulder part having a spout sealed at the tip. The conical protrusion attached to the above is pushed into the spout to be opened. In this prior art, since the rotation of the cap at the time of screwing is used for opening, it has various advantages such as easy opening with a relatively small force, but the formed opening hole is limited to a very small one, There is also a problem that it is difficult to apply to a container that requires a relatively large opening hole.

  Similarly, in Patent Document 3 (Patent No. 3978224) previously proposed by the present applicant, an inner cap provided with a sealing film in a state where an opening prevention member is interposed between the inner cap and the cap body. In a bottle container of the type in which the container body filled with the contents is attached to the neck of the container body in a sealed state, the anti-opening member is removed and the container is opened for use, when the cap body is screwed into the inner cap again, It is described that the cutting blade attached to the cap body is rotated by a specific angle to leave the uncut portion and open the sealing film. In this prior art, since a small-diameter cutting blade is rotated and opened by screwing rotation of a large-diameter cap, even if the large-diameter cap is rotated with a relatively small force, a large rotational force or Since a pressing force is applied, there are various advantages such as the ability to form an opening hole that is relatively large and has few burrs on the edge of the opening hole other than the uncut portion. However, this technology is applied to a container body made of a material having relatively high flexibility and flexibility, such as a squeezed tube container, or a container body that forms a relatively small opening hole in which the rotational force of a large-diameter cap is greatly amplified. When trying to apply, not only a relatively large pressing force but also a large rotational force acts on the periphery of the sealing film, so that the problem that the peripheral part of the sealing film is abnormally deformed or broken is recognized. It was.

A spout that can pour out the contents of the container body when locked to the neck in a retaining state, the lower end of the opening means is formed shorter than the length of the neck of the container,
The unsealing / outlet member is moved to the body side together with the cap in accordance with the downward rotation of the cap at the time of screwing while being held by the holding portion of the cap. When the container is opened to form an opening hole, the engaging portion engages with the locking portion to prevent the container main body from coming off.
(2) The movement of the unsealing means provided in the unsealing / outlet member associated with the formation of the unsealing hole to the body side is a push-down movement without rotation, as described in (1) above container.

(13) The container according to any one of (1) to (12) above, wherein the container body is a flexible tube container.

By having the above-described features, the present invention exhibits remarkable effects as described in the following (a) to (ku).
(A) Since the cap rotation during screwing is used to open the openable portion to form the opening hole, a relatively large pressing force is applied to the opening means such as the cutting blade with a relatively small cap rotational force. Can be given.
(B) Although the rotation of the cap at the time of screwing is used to form the opening hole, the opening / spout member provided with the opening means is rotatably held by the cap. The forced rotation force does not act on the opening / outlet member. And since it is prevented from rotating with respect to the neck portion of the container body in which the openable portion is formed, or at least actively does not rotate, the peripheral portion of the openable portion is relatively large from the opening means such as a cutting blade. A pressing force acts, but at least a large rotational force does not act. Therefore, even a container made of a relatively flexible or flexible material such as a squeezed container or a relatively low strength material, or a container that forms a relatively small opening, A good opening hole can be easily formed without abnormally deforming or breaking the peripheral portion of the openable portion.
(C) If the opening / outlet member having an opening means such as a cutting blade is configured to be prevented from rotating with respect to the neck portion of the container body, the rotational force of the cutting blade does not act at all on the periphery of the openable portion. Abnormal deformation and destruction of the periphery of the openable portion can be better prevented. Moreover, the unsealing means including the cutting blade can form the cut line and the joint portion left without being cut within an accurate angular range.
(D) Since the pushing rib formed on the inner surface of the cutting blade at the lower part of the cylindrical member pushes down the sealing film on the inner side of the cut, it assists the downward drooping from the uncut portion of the sealing film. Further, the pushing rib enters between the cutting blade and the sealing film inside the cut, widens the clearance of the cut and reduces the contact resistance of the cutting blade, thereby further reducing the cap rotational force required for the push cutting.
(E) When the cutting blade is constituted by a plurality of continuous chevron-shaped cutting blade portions, the pressing force is dispersed, and the deformation of the peripheral portion of the sealing film due to the pressing force of the cutting blade can be better prevented.
(F) In the sealed sealing film, the portion other than the connecting portion left without being cut is pushed down by the flat portion where the cutting blade is not formed at the lower part of the cylindrical member, and the connecting portion is connected by the outer peripheral surface of the flat portion. Since it is suspended from the part and held in a state of being pressed against the inner peripheral surface of the neck of the container main body, it hardly interferes with the dispensing of the contents, and it mixes into the contents and floats to give a feeling of foreign matter Nor.
(G) When not in use, the cap, opening / outlet member, and opening prevention member can be attached to the neck of the container body after filling the contents in an integrated state, so the assembly of the container is easy in one step Can be.
(H) Whether or not it is unused can be clearly identified by the presence / absence of an opening prevention member, the presence / absence of locking of the opening / outlet member to the neck of the container body, the presence / absence of an opening hole at the tip of the neck, and the like.

(B) The cap includes a holding portion that can hold the opening / outlet member and a female helix that can be screwed into the male helix, and is detachably attached to the neck portion of the container body by the screwing. is there.
(C) The unsealing / spouting member is in a state in which the unsealing portion is unsealed at the neck of the container body by engaging the unsealing means for unsealing the openable portion to form an unsealing hole and the engaging portion. And a spout that can pour out the contents of the container body when the unsealing / outlet member is locked to the neck of the container body in a retaining state, and is held by the holding part of the cap. When the cap is rotated and screwed together with the cap, the engagement portion moves to the body portion side and the opening means opens the openable portion of the neck upper end portion to form the opening hole. Engages with the locking portion to prevent the neck of the container body from coming off. This movement toward the body portion is a parallel movement in the axial direction without forced rotation.

The container of the present invention can make the unused state of the container reliable and visible by further including an unsealing preventing member that prevents the unsealing means from coming into contact with the unsealable part in an unused state. . The unsealing prevention member is provided in an unused container, restricts the axial movement of the cap toward the container main body when the cap rotates during screwing, and moves in the axial direction together with the cap held by the cap holding part. A member for preventing the opening means formed on the opening / outlet member to come into contact with the openable portion, for example, an opening through which the cylindrical neck portion can penetrate, and the opening means can be opened. And a cylindrical portion having an axial length as a spacer for preventing contact with the portion.
If the container does not have an opening prevention member, keep the opening / outlet member separate from the container body or cap so that the openable part is not opened unintentionally, or the opening / outlet member is held. It is necessary to distribute and display the cap separately from the container body, etc., but if it has anti-opening members, it is inadvertent even if it is distributed and displayed with all of them assembled. Opening can be prevented.
At the start of use, the unsealing prevention member is removed, and the cap holding the unsealing / outlet member is screwed onto the neck of the container body. As the cap rotates in the screwing direction, the opening and spout member held in the cap moves in the axial direction together with the cap toward the body, and the opening means opens the openable portion at the tip of the neck. Form holes. At that time, the opening and spout member is locked to the neck portion of the container body, and thereafter functions as a spout member integral with the neck portion of the container body.

  The material of the container main body, the cap, the unsealing / outlet member, and the unsealing preventing member 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, etc. can be adopted depending on the contents, applications, components, and the like. In general, a synthetic resin is preferable in terms of lightness due to low specific gravity, ease of molding various aesthetic design containers and functional containers, and the like. Although the synthetic resin to be used is not limited, for example, an olefin-based resin such as polypropylene or polyethylene, a polyester-based resin such as PET, an ABS resin, or the like can be used depending on the contents, application, component parts, or the like.

  The contents filled in the container body are not limited, but are generally liquids, granules, powders, solid-liquid mixtures, pastes, frozen foods, cosmetics, detergents, various drugs, beverages, foods, etc. Etc. can be illustrated.

Below, each component is further demonstrated.
[Container body]
The container main body in the present invention includes at least a cylindrical neck portion and a trunk portion that is a main accommodating portion for contents. A shoulder portion that is inclined horizontally or downward may be provided between the body portion directly below the neck portion.
The cylindrical neck includes an openable portion, a locking portion that can lock the opening and spout member in a retaining state, and a male screw that can be screwed into a female spiral such as a female screw formed on the cap. And at least a male spiral.
The openable portion may be a sealing film that closes the upper end of the neck. It is desirable that the sealing film facilitates continuous push-cutting of the contact portion of the cutting blade by using the contact portion of the cutting blade constituting the opening means as a cutout portion having a thinner thickness than other portions.
The locking portion that can lock the opening / spout member in a retaining state is preferably an annular ridge protruding radially outward from the entire upper end of the upper small cylindrical portion constituting the cylindrical neck portion.
A male spiral such as a male screw can be formed on the outer peripheral surface of the lower large cylindrical portion constituting the cylindrical neck portion. The male spiral is preferably continuous, but can be provided intermittently, or can be either single or multiple.
When the opening means opens the openable portion or after the opening and spout member is locked to the cylindrical neck portion, the opening and spout member provided with the opening means rotates with respect to the neck portion. A non-rotating portion can be formed on the neck so as not to move. The anti-rotation portion formed on the neck portion may be a vertical rib that is in sliding contact with the axial protrusion on the inner surface of the outer tube of the unsealing / outlet member. It is preferable that a plurality of the vertical ribs are provided at equal intervals on the outer periphery of the upper small cylindrical portion constituting the cylindrical neck portion.
It is preferable that the container body includes a rotation limit restricting portion that restricts a rotation limit in the screwing direction with respect to the cap or the opening prevention member. Such a rotation limit restricting portion can be a rotation limit restricting protrusion formed at the base end portion of the neck portion and having a restricting surface substantially perpendicular to the tangent to the outer periphery of the base end portion. The regulation surface is most preferably perpendicular to the tangent to the outer periphery of the base end portion, but is acceptable if it is within a range of ± 40 degrees (preferably ± 20 degrees) with respect to the perpendicular surface. When the positioning protrusion formed on the cap or the unsealing prevention member faces the restriction surface, the base end portion holds the cap or the unsealing prevention member at that position. It is preferable to comprise a portion that engages with the surface opposite to the portion. As such an engaging portion, it is possible to use an overhanging projection that can be moved over by the elastic deformation of the positioning projection.
The body of the container can be of various shapes and structures such as rotational symmetry, rotational asymmetry, circular cross section, elliptical cross section, polygonal cross section, etc. It may be preferred that the cross section be elliptical.
The container body can be manufactured in a single process as a whole by injection molding, etc. In addition, the upper end of the flexible cylindrical tube constituting the body is held in the mold cavity and synthesized in the mold cavity It can be manufactured by injecting a resin to injection-mold the neck and shoulder and integrating the synthetic resin of the shoulder with the upper end of the tube. In the case of a container main body with an open bottom of the container, a backflow preventing member that prevents backflow of the poured out contents into the container main body may be inserted and fixed into the neck from the bottom opening. Then, after filling the contents from the lower end opening, the lower end of the body portion may be sealed by an appropriate sealing means such as an ultrasonic welding method or a hot plate heat sealing method. In addition, after filling the contents from the neck opening at the neck connected to the trunk, an inner cap having an openable portion, a locking portion, a male spiral and, if necessary, a backflow prevention member is sealed and fixed to the neck. Thus, the container body can be formed by forming the neck portion. The resin portion such as the cylindrical tube of the trunk portion may have a multilayer structure including various resin layers such as a gas barrier layer and an adhesive layer. In the case of a bottle container, at least the openable portion can be made of an openable material such as resin, and the other can be made of glass or metal.

〔cap〕
The cap includes a holding portion that can hold the opening / outlet member and a female helix such as a female screw that can be screwed into the male helix on the outer peripheral surface of the neck of the container main body. It is configured to be detachably attached to the neck portion through an opening prevention member or without an opening prevention member.
Such a cap includes a ceiling wall, an outer cylinder that hangs down from the outer periphery of the ceiling wall, and an inner cylinder that is centered on the outer cylinder and hangs down from the lower surface of the ceiling wall. It can have a female spiral and a holding part that engages with the opening and spout member.
The holding part holds the opening / outlet member provided with the opening means loosely so as not to drop out of the cap, and can be moved in the axial direction of the neck of the container body together with the cap when the cap is rotated. It is possible to provide an annular protrusion on the inner peripheral surface of the inner cylinder that fits loosely into the annular recess on the outer peripheral surface of the unsealing / outlet member. The opening / outlet member loosely held in the inner cylinder of the cap can be held without pressing against the packing fixed to the inner wall of the ceiling wall of the cap by adhesion etc. The elasticity can be maintained. When opening the container and starting to use it, the opening / outlet member is locked to the neck of the container body, and when the cap is tightened, the ceiling wall top surface of the opening / outlet member is the ceiling surface of the cap inner cylinder Or it can be made to contact | abut to the packing fixed to the ceiling surface. Even after the opening / outlet member is locked to the neck of the container main body, the holding portion and the annular recess can contact each other. It is pre-configured so as not to hinder.
Rotation formed on the container body neck so that the cap does not rotate beyond the rotation limit and is held at the rotation limit position when it is attached to the container body neck by rotating in the screwing direction. It is preferable to provide a positioning projection that engages with a positioning recess between the limit regulating portion and the overpass projection.
As a member that can seal the spout of the opening / spout member that is locked to the neck of the container main body, a packing that is fixed to the inner surface of the ceiling wall of the cap by adhesion or the like can be used. A plug formed on the cap lid can also be used. When using a plug formed on the lid of the hinge cap, an opening is formed in the ceiling wall, and the spout exposed from the opening can be closed with a plug on the inner surface of the lid supported by the hinge. Configure as follows.
Examples of the cap material include synthetic resins such as polypropylene, glass, and metals.

[Opening / Outlet Material]
The unsealing / outlet member engages with the unsealing means for unsealing the openable portion to form an unsealing hole and the locking portion of the neck of the container body when the unsealing hole is formed. An engagement portion for preventing the cap body from being detached, and a spout for allowing the contents of the container body to be poured out when the opening / spouting member is secured to the neck portion of the container body. While being held by the holding portion, the cap moves together with the cap to the body side with the rotation of the cap during screwing, and the opening means opens the openable portion at the upper end of the neck to form an opening hole. At this time, the engaging portion is configured to engage with the locking portion and to be prevented from being detached from the neck portion of the container body.
After removing the anti-opening member, when the cap is put on the neck and rotated in the screwing direction, the opening and spout member held by the cap moves axially to the body side together with the cap, and the opening means is at the upper end of the neck. Open the openable part to form an opening hole, and with the annular seal part of the opening / outlet member in contact with the annular seal surface around the opening hole, the opening / outlet member is against the neck of the container body. The unsealing and spout member is locked in the retaining state and functions as a spout member integrated with the container body.
Since the rotation of the cap at the time of screwing is used to open the openable portion to form the opening hole, a relatively large pressing force can be applied to the opening means including the cutting blade with a relatively small cap rotational force. it can. The opening and spout member is only held loosely by the cap when the opening means opens the openable portion, and does not rotate integrally with the cap. However, at least a large rotational force does not act. Therefore, even a container made of a material with relatively high flexibility or flexibility, such as a squeezed container, or a material with relatively low strength, or a container that forms a relatively small opening hole, A good opening hole can be easily formed without abnormally deforming or breaking the peripheral portion of the openable portion. If the opening / outlet member is configured to be prevented from rotating against the neck of the container body, the rotational force of the cutting blade does not act at all on the periphery of the openable portion, so abnormal deformation or destruction of the peripheral portion of the openable portion Can be better prevented.
Such an opening and spout member is a ring-shaped ceiling wall in which a spout is formed at the center, and a cylindrical portion that hangs down from the ceiling wall, and has an outer cylinder having a through hole with a horizontally long rectangular cross section, Consists of an inner cylinder that is concentric with the outer cylinder and has an opening means formed in the lower part thereof, and a cylindrical part that is provided between the inner and outer cylinders and that has a ring-shaped gap with an annular ceiling surface serving as an annular seal part. it can.
The unsealing means for unsealing the openable portion to form the unsealing hole preferably includes a cutting blade formed at the lower part of the inner cylinder constituting the unsealing / outlet member. The range in which the cutting blade forms a cut by pressing can be preferably in the range of 240 to 340 degrees, more preferably 260 to 320 degrees around the openable portion such as the sealing film. When the cutting blade that pushes through such a range is composed of a plurality of (preferably 2 to 5) chevron-shaped cutting blade portions, the push cutting pressure is dispersed, and the sealing film peripheral portion due to the push cutting pressure of the cutting blade is distributed. Deformation can be better prevented. One or more pushing ribs extending in the axial direction can be formed on the inner peripheral surface of the cutting blade formed in the lower part of the inner cylinder. The push rib is preferably configured to extend rearward in the axial direction from a position slightly behind the tip of some or all of the plurality of angle cutting edges. The push rib pushes down the sealing film inside the cut formed by the cutting blade and forms a clearance so that the inner peripheral surface of the cutting blade and the sealing film inside the cut do not stick into the cut. Thus, the contact resistance can be reduced, and the force required to push the sealing film with the cutting blade can be reduced.
The portion in the range of 20 to 120 degrees (preferably 40 to 100 degrees) that is not cut by the cutting blade functions as a coupling portion that does not mix the pressed sealing film into the contents in the container. In order to form such a coupling part, it is preferable to form a flat part in the lower part where the cutting edge of the cylindrical member is not formed. The cylindrical member including the flat portion in the lower part is pressed and the sealing film pressed down by the pressing rib is suspended from the coupling part, deformed so as to be pressed against the inner peripheral surface of the container body neck, and maintained in that state. Therefore, the sealed sealing film does not hinder the smooth dispensing of the contents.
When the opening means opens the openable portion, or after the opening / outlet member is locked to the cylindrical neck, the opening / outlet member having the opening means is attached to the neck. It is preferable to form a rotation preventing portion so as not to rotate. The anti-rotation portion formed on the opening / outlet member may be an axial ridge that extends in the axial direction on the inner peripheral surface of the outer cylinder constituting the cylindrical portion and slidably contacts the vertical rib on the outer peripheral surface of the neck portion. it can. A plurality of the axial ridges are preferably provided at equal intervals in the circumferential direction so that the tip is tapered so as to be in sliding contact with the vertical rib at any position. By forming such an anti-rotation part, abnormal deformation and destruction of the peripheral part of the openable part can be better prevented, and an accurate angular range between the cut and the joint part left unbroken Furthermore, unnecessary rattling of the opening / outlet member after locking to the neck of the container body can be prevented.
The engagement part that keeps the unsealing / outlet member at the neck of the container body may be of any structure, but the lower part of the outer cylinder through hole with a horizontally long rectangular cross section protrudes from the inner peripheral surface of the outer cylinder One or two or more engaging protrusions may be formed.
The material of the opening and spout member is harder than the portion that can be opened, and examples of the synthetic resin include polyester resins such as PET.

[Opening prevention member]
The unsealing prevention member is provided in an unused container, restricts axial movement of the cap toward the body of the container body due to rotation of the cap during screwing, and opens the unsealing and spout member held by the cap. Means are prevented from contacting the openable portion.
As the opening prevention member having such a function, a member that can be interposed between the screwed cap and the container main body or the shoulder can be used. Although its shape and structure are not limited, in terms of aesthetic appearance, an opening through which a cylindrical neck portion can penetrate, and a cylindrical portion having an axial length as a spacer that is substantially the same in appearance outline as a cap or container body trunk portion. What it comprises is preferable.
The unsealing prevention member is configured to be coupled to the lower part of the cap (for example, the lower end surface of the outer cylinder) or the container body (for example, the upper surface of the shoulder part) through the easily cut coupling part, and can further ensure the unused state. However, it is preferable that the cap and the container main body are separated from each other because the cutting trace of the easily cut and bonded portion does not remain and the degree of freedom in designing the design of the unused container increases. Moreover, it is preferable that the opening prevention member has an appearance (for example, different colors) that can be clearly distinguished from the cap and the container body so that the unused state and the use state of the container body can be understood at a glance.
It is preferable that the opening prevention member when separated from the cap or the container main body can be handled integrally with the cap, because attachment or detachment to the neck of the container main body is facilitated. In order to be able to handle the cap integrally with the cap, the opening prevention member can include a fitting piece whose outer peripheral surface is elastically pressed against the inner peripheral surface of the cap outer cylinder. The fitting pieces can be formed continuously around the entire circumference, but from the viewpoint of material saving, a plurality (for example, 2 to 6 pieces) may be provided intermittently at predetermined intervals in the circumferential direction. preferable.
In order to restrict the rotation limit when attaching the cap holding the unsealing prevention member integrally to the neck of the container body in the screwing direction, the unsealing prevention member is attached to the neck end of the container body. It is preferable to provide a positioning projection that can be engaged with the formed positioning recess.
Examples of the material for the opening prevention member include relatively hard synthetic resins such as ABS, glass, and metals.

  Hereinafter, the present invention will be described in more detail based on examples of the present invention. However, the present invention is not limited to these examples, and it is needless to say that the design can be changed as appropriate without departing from the gist of the present invention. .

<Cap 4>
FIG. 3A shows a longitudinal sectional view of the cap 4 at the top of the unused container 1 (the left side from the center line is an elliptical long axis side longitudinal sectional view, and the right side is an elliptical short axis side longitudinal sectional view). FIG. 7 (a) shows a longitudinal sectional view of the cap 4 on the upper part of the container 1 after the start of use (the left side from the center line is an elliptical long axis side longitudinal sectional view, and the right side is an elliptical short axis side longitudinal sectional view). Has been.
The cap 4 has an elliptical ceiling wall 41, an outer cylinder 42 having an elliptical cross section that hangs from the outer periphery of the ceiling wall 41, a cylindrical inner cylinder 43 that is in the outer cylinder 42 and hangs from the ceiling wall 41, A disk-like packing 44 fixed to the inner surface of the ceiling wall 41 in the inner cylinder 43 by means such as adhesion is provided.
On the inner surface of the inner cylinder 43, there is an annular protrusion 43b that fits loosely into the annular recess 54a on the outer peripheral surface of the unsealing / outlet member 5 and holds the unsealing / outlet member 5 so as not to fall from the inside of the inner cylinder 43. In the lower part of the inner surface of the inner cylinder 43, there are two female screws 43 a that are screwed into the male screw 27 provided on the outer peripheral surface of the large cylindrical portion 21 b of the neck portion 21 of the container body 2. At the lower end, positioning protrusions 45 (see FIG. 7 (b)) that can engage with the positioning recesses 28c formed in the base end 21c of the neck portion 21 of the container body 2 are formed.
Since the fitting piece 32 formed on the upper surface of the unsealing prevention member 3 is fitted to the inner surface of the lower portion of the outer cylinder 42 of the cap 4 in the unused state, the cap 4 and the unsealing prevention member 3 can be handled integrally. The attachment and detachment of the container body 2 with respect to the neck can be performed in one step.
At the start of use, after removing the unsealing prevention member 3 from the lower part of the outer cylinder 42 of the cap 4, the cap 4 with the unsealing / outlet member 5 held in the inner cylinder 43 is attached to the neck portion 21 of the container body 2.

<Opening and spout member 5>
4 and 5 show the opening and spout member 5. 4 (a) is a plan view, FIG. 4 (b) is a front view, FIG. 4 (c) is a side view, FIG. 5 (a) is a longitudinal sectional view, and FIG. 5 (b) is a partial bottom view.
The opening and spout member 5 includes a ring-shaped ceiling wall 51 having a spout 52 formed at the center, and a cylindrical portion 53 that hangs down from the ceiling wall 51. The cylindrical portion 53 includes an outer cylinder 54, an inner cylinder 56 concentric with the outer cylinder 54, and a ring-shaped gap 55 therebetween.
On the outer peripheral surface of the upper portion of the outer cylinder 54, an annular recess 54 a is formed that fits loosely with the annular protrusion 43 b on the inner peripheral surface of the inner cylinder 43 of the cap 4. The annular recess 54a is formed with an outer cylinder through hole 54b (see FIG. 4C) having a horizontally long rectangular cross section provided at two point-symmetric positions. The bottom surface of the outer cylinder through-hole 54b having a horizontally long rectangular cross section projects from the inner peripheral surface of the outer cylinder 54 and can engage with the lower surface of the annular ridge 25 projecting outward from the upper end of the neck 21 of the container body 2. An engaging protrusion 54 having 54f is formed [see FIG. 5 (a)].
Twelve axial ridges 54c extending in the axial direction are formed at equal intervals on the inner peripheral surface lower portion of the outer cylinder 54, and between the adjacent axial ridges 54c, the container main body 2 neck portion 21 small cylindrical portion A vertical groove 54d into which the vertical rib 26 provided on the outer peripheral surface 21 can enter is formed. The lower end of each axial protrusion 54c is tapered (tapered) so that when the abutment with the upper end of the vertical rib 26 is made, the unsealing / outlet member 5 rotates by a predetermined small angle and the vertical rib 26 enters the vertical groove 54d. Shape). Therefore, the opening and spout member 5 is prevented from rotating because the vertical rib 26 enters the vertical groove 54d at any rotational position with respect to the neck portion 21 of the container body 2.
The lower part of the inner cylinder 56 functions as an opening means, and a cutting edge 57 and a flat part 58 that can open the sealing film 24 at the upper end of the neck 21 of the container body 2 are formed. FIG. 6 is a development view of the lower part of the inner cylinder 56 including the cutting edge 57. The cutting blade 57 is formed over a range of 280 degrees of the inner cylinder 56, and is composed of three cutting blade portions 57a to 57c protruding downward in a mountain shape. The central cutting edge portion 57b is formed in a bilaterally symmetrical chevron shape, but the cutting blade portions 57a and 57c on both sides are formed in a bilaterally asymmetrical chevron shape whose tip is offset toward the central cutting edge portion 57b side. ing. On the inner peripheral surfaces of the cutting blade portions 57a and 57c on both sides, push ribs 59 are formed that extend upward in the axial direction from positions slightly above the tips of the cutting blade portions 57a and 57c. In the remaining 80-degree range where the cutting edge below the inner cylinder 56 is not formed, the lower end is formed in the flat portion 58. With such a cutting edge 57, the periphery of the sealing film 24 is gradually pushed to form a cut in a range of 280 degrees, and the push rib pushes down the sealing film 24 inside the cut and The sealing film 24 inside the cut line is deformed to the center side, and a clearance is formed between the inner peripheral surface of the cutting edge 57 and the sealing film 24 inside the cut line to reduce the contact resistance received by the cutting edge 57. Let As described above, the opening and spout member 5 including the inner cylinder 56 with the cutting edge 57 formed in the lower portion is prevented from rotating with respect to the container body 2 neck portion 21, so that the range of 280 degrees is accurately cut and cut. In the stop film 24, the portion corresponding to the remaining 80 degree range is accurately left as a connecting portion, and the portions other than the connecting portion are further pushed down by the flat portion 58, and the outer peripheral surface of the flat portion 58 It hangs down from the connecting portion and is held in a state of being pressed against the inner peripheral surface of the container body 2 neck portion 21 (see the sealing film 24 in FIG. 7A). For this reason, the sealed sealing film 24 hardly interferes with the dispensing of the contents, and does not give a sense of foreign matter by being mixed or floating in the contents. When the opening means including the cutting edge 57 opens the sealing film 24 to form the opening hole, the annular sealing surface around the opening hole at the tip of the container body 2 neck portion 21 is the ring-shaped gap 55 of the opening / outlet member 5. The abutment surface 54f on the upper surface of the engagement protrusion 54e on the inner surface of the outer cylinder 54 engages with the lower surface of the annular protrusion 25 at the tip of the container body 2 neck portion 21 to contact the ceiling surface annular seal portion. Is locked to the container body 2 neck portion 21 in a retaining state. Since the opening 52 of the ceiling wall 51 communicates with the opening / outlet member 5 through the opening hole and the inside of the inner cylinder 56, the opening / outlet member 5 functions as an outlet member integrated with the neck portion 21 of the container body.
When the unsealing / outlet member 5 is locked to the neck portion 21 of the container body 2 in a retaining state, the outer cylinder 54 covers the peripheral surface of the small cylindrical portion 21a at the upper portion of the neck portion 21 and the large cylindrical portion 21b at the lower portion of the neck portion 21. Results in an outline that roughly matches.

<Opening prevention member 3>
3A is a longitudinal sectional view of the unsealing prevention member 3 provided at the lower end of the cap 4 on the upper portion of the container 1 in an unused state (the left side from the center line is the longitudinal longitudinal axis side longitudinal sectional view, and the right side is the elliptical short section). A shaft side longitudinal sectional view) is shown.
The unsealing prevention member 3 configured separately from the container main body 2 and the cap 4 of the present embodiment has a cylindrical part 31 having an outer peripheral part of an elliptical cross section continuously extending from the lower end of the outer cylinder 42 of the cap 4. , A fitting piece 32 having an outer peripheral surface to be fitted to the inner peripheral surface of the lower portion of the cap 4 outer cylinder 42, an opening 33 through which the neck portion 21 of the container body 2 can penetrate, and a neck portion 21 proximal end portion 21 c of the container body 2 A positioning projection 34 is formed that can engage with the positioning recess 28c formed in FIG. 3 (see FIG. 3B).
Four fitting pieces 32 are provided intermittently in the circumferential direction corresponding to the four ends of the elliptical long axis side both ends and the elliptical short axis side both ends, and the outer peripheral surfaces thereof are the inner periphery of the cap 4 outer cylinder 42. Since the fitting is performed so as to elastically press the surface, the anti-opening member 3 can be held so as not to fall below the cap 4. Therefore, attachment and detachment with respect to the container body 2 neck 21 can be performed together with the cap 4 in one step.

<Unopened container 1>
1 and 3 show the unopened container 1. 1 (a) is a plan view, FIG. 1 (b) is a front view, FIG. 1 (c) is a side view, and FIG. 3 (a) is a partially enlarged longitudinal sectional view (the left side from the center line is the ellipse major axis side) FIG. 3B is a partially enlarged cross-sectional view of the overpass / rotation limit restricting portion 28. FIG.
The unused container 1 includes a container body 2, an opening prevention member 3, a cap 4, and an opening / outlet member 5 that is mounted in the cap 4 and cannot be seen from the outside.
When the container body 2 is a tube container in which the upper end portion of the neck portion 21 is sealed with the sealing film 24 and the lower end of the cylindrical tube is opened, the lower end of the trunk portion is sealed after the contents are filled from the lower end opening. Thus, the contents are held in a sealed state in the container body 2 (Note that FIG. 1 and FIG. 8 omit the sealed state and the sealed portion of the lower end opening for the sake of convenience).
The cap 4 before being attached to the container body 2 is provided with an opening / spouting member 5 and an opening prevention member 3, and the cap 4, the opening prevention member 3, and the opening / spouting member 5 are integrally handled. It is configured to be able to.
In order to attach the opening / spouting member 5 to the cap 4, the opening / spouting member 5 is inserted into the inner cylinder 43 of the cap 2, and the annular recess 54 a on the outer peripheral surface thereof is connected to the annular protrusion on the inner surface of the inner cylinder 43. It is made to fit in the part 43b. This fitting is so loose that the unsealing / outlet member 5 does not fall from the inside of the inner cylinder 43, and the unsealing / outlet member 5 is allowed to move slightly up and down inside the inner cylinder 43. Therefore, the unsealing / outlet member 5 is not pressed against the packing 44 on the inner surface of the cap 4 ceiling wall 41, and the elasticity of the packing can be maintained without contraction.
The unsealing prevention member 3 is attached to the cap 4 by pushing the four fitting pieces 32 of the unsealing prevention member 3 into the outer cylinder 42 of the cap 4. The fitting between the outer peripheral surface of the fitting piece 32 and the inner peripheral surface of the cap 4 outer cylinder 42 is performed so that both surfaces are elastically pressed during fitting so that the unsealing prevention member 3 does not fall off the cap 4. The dimensions of the fitting piece 32 and the outer cylinder 42 are designed so that the unsealing prevention member 3 can be removed without requiring a large force when the person removes the unsealing prevention member 3.
In this way, the cap 4 on which the unsealing / outlet member 5 and the unsealing preventing member 3 are integrally attached is put on the neck portion 21 of the container body 2 filled with the contents, and the outer peripheral surface of the neck portion 21 large cylindrical portion 21b. The male screw 27 and the female screw 43a on the inner surface of the inner cylinder 43 of the cap 4 are screwed together, and the cap 4 is rotated in the screwing direction. When the cap 4 rotates a predetermined amount in the screwing direction and the positioning protrusion 34 of the unsealing prevention member 3 gets over the overhanging protrusion 28a of the neck 21 base end 21c of the container main body 2 and contacts the rotation limit restricting protrusion 28b, The positioning projection 34 is held in the positioning recess 28c between the overpass projection 28a and the rotation limit regulating projection 28b, and the cap 4 is in the direction of loosening the screw with a predetermined weak force. The cutting blade 57 below the inner cylinder 56 of the unsealing / pouring member does not come into contact with the sealing film 24 at the upper end of the neck 21 of the container body 2, and the sealing film 24 is held in a sealed state. The cap 4 in this state cannot rotate in the screwing direction, but in the anti-screwing direction, the positioning projection 34 can get over the curved surface of the projection 28 (a) by a strong force and rotate.
As described above, the container 1 of the present embodiment is distributed in a state in which the cap 4 in which the unsealing / outlet member 5 and the unsealing prevention member 3 are integrally attached to the neck portion 21 of the unopened container body 2 is assembled. Can be used for exhibitions. Therefore, the container main body 2 is not attached by attaching the anti-opening member 3 or removing the cap 4 integrally attached with the anti-opening member 3 and confirming that the sealing film 24 is not opened. You can easily know that it is in use.

<Opened container 1>
7 and 8 show the container 1 in an opened state. 7 (a) is a partially enlarged longitudinal sectional view (the left side from the center line is an elliptical long axis side longitudinal sectional view, the right side is an elliptical short axis side longitudinal sectional view), and FIG. FIG. 8A is a plan view, FIG. 8B is a front view, and FIG. 8C is a side view.
In order to open the unused container 1 shown in FIGS. 1 and 3 to use it, first, the cap 4 on which the unsealing / outlet member 5 and the unsealing prevention member 3 are integrally attached is loosened with screws. Rotate in the direction and remove from the neck 21 of the container body 2. Next, after removing the unsealing prevention member 3 from the cap 4 on which the unsealing / outlet member 5 and the unsealing prevention member 3 are integrally attached, the cap 4 on which the unsealing / outlet member 5 is integrally attached is again attached. Covering the neck portion 21 of the container body 2, the male screw 27 on the outer peripheral surface of the large cylindrical portion 21b of the neck portion 21 and the female screw 43a on the inner surface of the inner cylinder 43 of the cap 4 are screwed together, and the cap 4 is rotated in the screwing direction. At that time, the cap 4 is moved to the body portion 23 side of the container body 2 by the screwing, but since the unsealing prevention member 3 is removed, the cap 4 can be rotated more by that amount and moved to the body portion 23 side. The moving distance of is also increased. Along with the axial movement of the cap 4 toward the body portion 23 side, the unsealing / outlet member 5 held in the inner cylinder 43 of the cap 4 also moves in the axial direction. The cutting edge 57 at the bottom of the cylinder 56 contacts the sealing film 24 at the tip of the container body 2 neck 21 and is a longitudinal groove 54d between adjacent axial protrusions 54c on the inner peripheral surface of the unsealing / outlet member 5 outer cylinder 54. The vertical ribs 26 provided on the outer peripheral surface of the container main body 2 neck portion 21 and the small cylindrical portion 21a enter and engage. When the cap 4 is further rotated, the opening and spout member 5 further moves in the axial direction while the vertical ribs 26 are in sliding contact with the vertical grooves 54 between the adjacent axial ridges 54 c, and are formed below the inner cylinder 56. The cutting edge 57 composed of the three angle-shaped cutting edge portions 57a to 57c is formed by forming a cut line on the outer periphery of the sealing film 24 by pushing and cutting, widening the range of the cut line and finally having a continuous 280 degree cut line. Form. The sealing film on the inner side of the cut is pushed downward by the pressing rib formed on the inner surface of the cutting edge portions 57a and 57c, and the pressing rib is provided between the cutting blade portions 57a and 57c and the sealing film on the inner side of the cutting edge. Then, a gap is formed between the two, the contact resistance of the inner surface of the cutting edge 57 is reduced, and the force required for pressing is reduced.
In the sealing film 24 in which the range of 280 degrees is pushed by the cutting edge 57, the remaining 80 degrees corresponding to the flat part 58 where the cutting edge 57 is not formed is left without being cut as a connection part. The portions other than the portion are further pushed down by the flat portion 58, suspended from the connection portion by the outer peripheral surface of the flat portion 58, and held in a state of being pressed against the inner peripheral surface of the container body 2 neck portion 21.
Thus, when the cutting blade 57 opened the sealing film 24 at the upper end portion of the neck portion 21 to form an opening hole, the opening and spout member 5 was provided on the ceiling surface of the ring-shaped gap 55 of the cylindrical portion 53. The annular seal portion and the annular seal surface around the opening hole are in contact with each other, and in this state, the engagement surface 54f at the upper portion of the engagement projection 54e of the outer tube 54 is on the lower surface of the distal end annular protrusion 25 of the container body 2 neck portion 21. The unsealing / outlet member 5 is engaged with the neck portion 21 of the container body 2 so as to prevent the unsealing, and the unsealing / outlet member 5 has an opening 52 through the opening hole and the neck portion 21. After that, it functions as a spout member of the container body 2. When the cap 4 is further rotated in the screwing direction in this state, the packing 44 on the inner surface of the cap 4 ceiling wall 41 is pressed against the ceiling wall 51 of the unsealing / outlet member 5, and the outlet 52 is sealed by the packing 44. At the same time, the positioning projection 45 of the cap 4 is positioned in the positioning recess 28c between the overhanging projection 28a and the rotation limit regulating projection 28b of the container body 2 neck 21 base end 21c, and the cap 4 is only in the screwing direction. In addition, the rotation in the screw loosening direction cannot be performed with a predetermined weak force.
In order to use the contents in the container main body 2 after the opening hole is formed, the cap 4 is strongly rotated in the screw loosening direction, and the engagement between the positioning protrusion 45 and the overpass protrusion 28a is engaged with at least one of them. It is removed by elastic deformation and removed from the neck portion 21 of the container body 2 by continuing to rotate in the screw loosening direction.
The use of the unsealed container body 2 means that the unsealing prevention member 3 has been removed, or that the unsealing / outlet member 5 has been locked to the container body 2 neck 21 after the cap 4 has been removed. This can be easily confirmed.

  Although the container with the opening means of the present invention utilizes the rotation of the cap at the time of screwing to form the opening hole, the cylindrical member including the opening means is prevented from rotating with respect to the neck portion of the container body on which the openable part is formed. Or at least not actively rotating, so that a relatively large pressing force from the cutting edge acts on the periphery of the openable portion, but at least a large rotational force does not act. Therefore, the present invention can be applied to a container made of a material having high flexibility and flexibility, a container having a relatively low strength, a container in which the opening hole needs to be made small, and the like. For example, it can be suitably used as a squeeze tube container for various cosmetics. The container with an opening means of the present invention can be applied to a cap type that opens and closes by screwing and a cap type that opens and closes a lid supported by a hinge.
