Description

  The present invention relates to a container with a sealing ball and a cap used therefor, for example, containing a sparkling beverage represented by a beverage called ramune, specifically a carbonated beverage in a hard container such as a glass bottle, A sealing ball made of a hard material such as a glass ball placed on the inside of the outlet formed by a resin cap attached to the mouth is pressed against the receiving rib on the inner periphery of the outlet by receiving the gas pressure of the beverage. The present invention relates to a container with a sealing ball and a cap used therefor.

  As a container for such a ramune beverage, a dedicated glass bottle is originally used. This glass bottle has an O-ring packing fitted to the inner periphery of the mouth portion as an initial form, but has a mouth portion of a size that can be filled with a sealing ball, and a sealing ball is placed under the mouth portion. It has a constricted part which prevents falling to the bottom part. The glass bottle into which the sealing ball has been placed is baked to narrow the mouth, and is shaped into a sealed form in which the sealing ball cannot come out. The glass bottle after shaping is filled with the ramune beverage and then inverted to move the sealing ball onto the O-ring packing of the mouth facing downward, and the gas pressure of the beverage, specifically the pressure of carbon dioxide gas Thus, the mouth portion is sealed from the inside by crimping to the O-ring packing, and thereafter the sealed state is stabilized regardless of the direction of the glass bottle. As is well known, the downward opening plug shaft in the center of the stopper is applied to the sealing ball through the outlet, and the large diameter head is pushed over the gas pressure and sealed. Push the ball away from the O-ring packing and drop it into the constricted part with the release of the gas pressure. After that, even if the glass bottle is turned upside down again, the leakage of the beverage and the outflow of gas up to that time Insufficient gas pressure is generated due to, and the plug is in an open state in which sealing with the sealing ball is prevented.

  On the other hand, such a glass bottle requires a post-process that narrows the mouth part by mouth baking, which is troublesome and expensive. Therefore, a retrofitting cap is provided at the mouth part of the bottle as there is no such inconvenience. Thus, there is known a technique that enables sealing using a gas pressure by a sealing ball and conventional opening (see, for example, Patent Documents 1 to 5).

  In Patent Documents 4 and 5, a soft inner member such as an elastomer that performs sealing with a sealing ball and holding the sealing ball at a sealing position, and the inner member is in a state of being prevented from coming off at the mouth of the bottle. Combined with a slightly hard outer member such as polypropylene that is attached to the mouth so that it is not inadvertently removed from the mouth, making use of the elasticity of the inner member under a back-up condition with reliable mounting by the outer member A technique for easily sealing with a sealing ball, holding the sealing ball at a sealing position, and opening the cap is disclosed. In this case, after filling the glass bottle with the beverage, there is an advantage that the sealing can be completed without the trouble of inverting the glass bottle only by retrofitting a cap holding the sealing ball in the sealing position. Moreover, the sealing ball is held by the cap in the sealing position by the elastic force of the inner member, and the elastic holding force of the inner member is overcome and sealed with the opening operation of dropping the sealing ball by the opening tool. Since the holding in the position can be released without difficulty, there is no particular inconvenience in opening the plug.

Patent documents 1 to 3 are one caps made of a hard resin such as polyethylene or polypropylene, and the sealing ball is made sure that it cannot be inadvertently removed from the glass bottle by utilizing the rigidity of the resin material. And exhibiting necessary elasticity due to its shape relationship, sealing with a sealing ball, holding the sealing ball in a sealing position (excluding the one described in Patent Document 2) is reliable and A technique is disclosed which is easy and can be easily opened with a drop of the sealing ball from the sealing position.
Japanese Patent Laid-Open No. 5-27852 JP-A-61-27422 Japanese Utility Model Publication No. 62-152939 JP 2001-240090 A Japanese Utility Model Publication No. 4-118342

  By the way, recently, a product made of a plurality of types of materials is required to be collected separately by material. From this aspect, compared to caps made of one member described in Patent Documents 1 to 3, caps made of two members such as those described in Patent Documents 4 and 5 are used in the separation work and handling of separation and collection. It is disadvantageous and also disadvantageous in terms of product cost.

  In addition, it is convenient if the cap can be easily removed for separation and collection. For this purpose, a mounting structure using a screw as described in Patent Document 2 is advantageous. However, in this case, there is a problem that removal due to mischief and screw loosening due to inadvertent external force cannot be prevented. Therefore, a safety cover such as shrink wrapping as described in Patent Document 2 is applied, or the cap is annularly engaged with the annular protrusion of the bottle at the final stage of screw tightening as in Patent Document 4. Employs an engagement structure in which the part engages in the axial direction with a forced fit, or engages the belt-like engagement part in the wide groove of the bottle as in Patent Documents 1 and 5 Alternatively, as described in Patent Documents 1 and 3, a plurality of annular engaging portions are engaged with each other in a forcibly fitted state in the axial direction. However, the safety cover is easily made to the extent that the screw is loosened without being damaged, which may cause gas leakage and beverage leakage. On the other hand, if the engagement in the forced fit state using a hard resin is adopted, even if it can be mounted without difficulty by a machine, it is difficult to remove by hand as described in Patent Document 1, and it is easy to separate This is inconvenient for separation for recovery. If this is handled by a soft resin such as an elastomer, the compatibility with mischief and unauthorized external force is reduced.

  Further, in the case of using a single rigid resin member, the seal is subjected to gas pressure with its elastic expansion in the inner cylinder wall extending into the bottle mouth from the outlet opening in the ceiling wall of the cap. The stopper ball is received from below and stabilized in a sealed state, while the outer cylinder wall extending from the outer periphery of the ceiling wall to the outside of the bottle mouth is screwed or forcibly fitted to the bottle. The familiarity with the mouth and the sealing ball is poor, and the seal is likely to be insufficient.

  Therefore, the one described in Patent Document 3 is provided with two annular seal protrusions that are press-fitted into the inner periphery of the bottle on the outer periphery of the thick base portion of the inner cylinder wall, and further, the lower straight straight lower half portion. The sealing ball is received and received at the lower end of the thick base so as to be in a sealed state, and the lower half accepts the upper and lower hemispheres of the sealing ball to bulge and hold the bottle and The sealing performance for the sealing ball is improved. In addition, the one described in Patent Document 2 is provided with an annular seal portion that presses against the top surface of the bottle mouth on the ceiling wall of the cap, and is press-fitted into the inner periphery of the bottle mouth on the thin inner wall. An outwardly extending action when the sealing ball is received and stabilized in a sealed state by a further thin elastic lip extending from the lower end portion of the inner cylinder wall and extending upward from the lower end of the inner cylindrical wall Thus, the annular seal portion is pressed against the inner periphery of the bottle mouth to improve the sealing performance against the bottle mouth, and the flexibility of the elastic lip makes it well compatible with the sealing ball and enhances the sealing performance. In addition to receiving the sealing ball on the inner peripheral upper part of the thin inner cylinder wall to be in a sealed state, the lower hemisphere part of the sealing ball is also received in the inner cylinder wall and held at the sealing position, At that time, the tip of the thin elastic lip that is turned upward outward by the expansion is pressed more strongly against the inner periphery of the bottle mouth, thereby improving the sealing performance between the bottle mouth and the sealing ball. . Furthermore, in the thing of patent document 1, in addition to providing the cyclic | annular seal | sticker part which press-contacts the other on one side of the ceiling wall of a cap, and the top | upper surface of a bottle, the inside of a bottle mouth is provided in the base outer periphery of an inner cylinder wall. An annular seal portion that is press-fitted into the periphery is provided, and the annular seal of the inner cylinder wall is bottled by expansion when the sealing ball is received in the inner cylinder wall until it is received by the rib and held in a sealed state. By further pressing against the inner periphery of the mouth, the sealing performance against the bottle and the sealing ball is enhanced.

  However, a large deformation of the very thin lower half of the inner cylinder wall as in the one described in Patent Document 3 is used, or the inner wall from the thin inner cylinder wall and its lower end as in the one described in Patent Document 2 With a structure that has a folded shape with an elastic lip folded upward outward and uses a compression between the inner periphery of the bottle mouth and the sealing ball to improve the sealing performance, the softness of the cap resin is reduced. If it is not raised, it will be easily damaged and the life will be short, and it will be even more so if the elastic lip folded inward is deformed from a convex curved state inside to a convex curved shape by receiving a sealing ball. . If this is avoided with a soft resin material, it becomes difficult to prevent loosening and unplugging due to mischief or inadvertent external force. Moreover, even if the sealing property with the bottle is enhanced by using a relatively thick inner cylindrical wall as in the case of Patent Document 1, a sealing ball is received in the thick inner cylindrical wall. In the configuration where the upper hemisphere is received by the receiving rib and the holding rib is held in contact with the lower hemisphere, the roundness of the glass ball, which is the sealing ball, may be low. There is no guarantee that the receiving ribs and holding ribs can be completely cut out, which tends to cause insufficient seal. This is especially true when the receiving rib is of a type that makes surface contact with the sealing ball. If this is handled with a soft resin material, it will be difficult to prevent loosening and unplugging due to mischief or inadvertent external force. In addition, as described in Patent Document 1, in order to make the receiving rib into a thin lip shape, it is easy to break with a hard resin and lacks durability, and with a soft resin, loosening due to mischief or inadvertent external force It becomes difficult to prevent and open.

  From the above, for separation and collection, there is no problem in mechanical mounting with a single resin member cap, loosening or opening due to mischief or inadvertent external force after mounting on a bottle and sealing it It is desirable to have a container with a sealing ball that can be easily separated by a person with a predetermined intent while also being able to prevent the damage sufficiently. Good quality is desired.

  Therefore, a main object of the present invention is to provide a container with a sealing ball that can be easily opened by a human hand under a predetermined intention without any problem in mechanical mounting with a single resin member cap, and a cap used therefor. In particular, the durability of the cap and the sealing performance against bottles and sealing balls are excellent.

  In order to achieve the above object, a container with a sealing ball of the present invention is mounted with a container made of a hard material such as glass and an annular seal projection between the mouth of the container and the mouth of the container. A cap made of resin, and received and held from below with elastic expansion in an inner cylindrical wall extending from the outlet opening in the ceiling wall of the cap into the mouth of the container, and in the container And a sealing ball that seals the outflow port from the inside by pressing onto the annular receiving rib formed on the inner periphery of the outflow port of the inner cylinder wall under the gas pressure of the beverage, and the cap is an outer peripheral part of the ceiling wall In addition to attaching the screw formed on the inner periphery of the outer tube wall extending downward from the screw to the screw formed on the outer periphery of the container mouth so that it can be attached and detached, the outer tube Sawtooth shape formed continuously in the circumferential direction below the wall screw A smaller number of serrated engagement protrusions formed on the outer periphery of the container mouth are crossed over one or more in the sliding direction and engaged in the direction of catching on the screw loosening side of the cap. One feature is that the attachment / detachment structure prevents inadvertent screw loosening of the cap.

  In such a configuration, the number of parts is small compared with a combination of a container made of a hard material such as glass and a cap made of one resin member, and the cap is made of resin and soft against the container and the sealing ball. Sealing with the container from the relationship of mounting with an annular seal ridge, sealing ball from below with elastic expansion in the inner cylindrical wall extending from the outlet of the ceiling wall into the mouth of the container The screw of the outer cylindrical wall extending downward from the outer peripheral part of the ceiling wall of the cap and the container of the container are obtained while obtaining the sealing performance with the sealing ball from the relationship of receiving and crimping and holding the annular receiving rib on the inner periphery of the outlet. In addition to a simple attachment / detachment structure by screwing with the screw on the outer periphery of the mouth, any of the serration-like engagement protrusions that are continuous in the circumferential direction on the outer cylinder wall end side at the final stage of mounting by screw matching Less mouth of the container Regardless of the variation in the position of the cap at the final stage of screwing the cap, it is probable that it faces the sliding direction with high probability, and the expansion of the outer cylinder wall in the circumferential position with a small amount and the contraction between them. With the elastic deformation of the cap, it can be easily and surely overcome by the normal screw tightening torque by the capper, etc., and engaged with the screw loosening side of the cap so that it is in the hooking direction. However, if the tampering or inadvertent external force is applied, the above-mentioned catch on the screw loosening side cannot be removed, but depending on the intentional manual operation on the screw loosening side, such as separation, the catching position is less in the circumferential direction. The cap-side engaging protrusion is relatively easily moved over the container-side engaging protrusion with the elastic deformation of the partial expansion and contraction in the circumferential direction of the outer cylinder wall, and the cap is removed. Hazuseru so.

  Such a container with a sealing ball having one feature is separately mounted on the mouth of a container made of a resin material and made of a hard material such as glass with an annular sealing protrusion between the mouth.

An annular sealing ridge having a sealing pressure contact margin is provided between the sealing ball and an upper hemisphere surrounding area which is located on the inner peripheral side and is crimped to the receiving rib to hold the sealing ball. Is another feature.

  In such a configuration, in addition to the case of the one feature, a base portion having annular sealing ridges on the outer peripheral side and the inner peripheral side of the inner cylindrical wall is received in the container mouth and the inner cylindrical wall. The tight fitting allowance and pressure contact allowance are received between the sealing balls held in a sealed state that are crimped to the receiving ribs without any escape, and the container mouth and sealing balls are made of hard resin material. It is possible to improve the adhesion, that is, the sealing property. In addition, the sealing of the container mouth and the sealing ball by the sealing ridges on the outer peripheral side and the inner peripheral side is performed in the upper hemisphere peripheral area and only contributes to the reception at the sealing position. The improvement does not hinder the opening and closing of the sealing ball that is held in the inner cylinder wall and dropped into the container.

  Such a container with a sealing ball having another feature is separately attached to the mouth of a container made of a resin material and made of a hard material such as glass with an annular sealing protrusion between the mouth. The inside of the inner cylinder wall that extends into the mouth of the container to be mounted from the outlet opening in the ceiling wall is received and held from below with its elastic expansion, and the beverage in the container to be mounted A cap of a container with a sealing ball in which a sealing ball that receives the gas pressure is pressed against an annular receiving rib formed on the inner periphery of the outlet of the inner cylinder wall so as to seal the outlet from the inside. In addition, the screw formed on the inner periphery of the outer cylinder wall extending downward from the outer periphery of the ceiling wall is fitted to the screw formed on the outer periphery of the container mouth so that it can be attached and detached. At the final stage of installation, the outer cylinder wall thread is continuously connected in the circumferential direction. The serrated engagement protrusions formed on the outer periphery of the container mouth are less than the number of serration engagement protrusions formed on the outer periphery of the container. The inner cylinder wall has an detachable structure that engages in the same direction to prevent inadvertent screw loosening, and the inner cylinder wall has an annular seal with a tight fitting margin between the mouth of the container An annular seal ridge having a seal pressure contact area between the upper hemisphere of the sealing ball that has a ridge on the outer periphery and is opposed to the receiving rib on the inner peripheral side of the annular seal ridge. There is provided a cap of a container with a sealing ball, which is characterized by having a sealing ball.

  The container with a sealing ball of the present invention is also composed of a container made of a hard material such as glass, and a resin cap attached to the mouth of the container with an annular sealing ridge between the mouth. The inner cylinder wall extending into the container mouth from the outlet opening in the ceiling wall of the cap is received and held from below with its elastic expansion, and the gas pressure of the beverage in the container is reduced. And a sealing ball that presses against an annular receiving rib formed on the inner periphery of the outlet of the inner cylinder wall and seals the outlet from the inside, and the cap extends outwardly from the outer periphery of the ceiling wall. In addition to fitting the screw formed on the inner periphery of the wall with the screw formed on the outer periphery of the container mouth so that it can be attached and detached, it is lower than the screw on the outer cylinder wall at the final stage of this attachment. A serrated engagement protrusion formed continuously in the circumferential direction A smaller number of serrated engagement protrusions formed on the outer circumference are passed over one or more in the sliding direction, and are engaged with each other in the direction of engagement in the hooking direction on the screw loosening side of the cap. The inner cylinder wall has an annular seal ridge with a tight fitting margin between the mouth of the container and the outer periphery of the inner cylinder wall on the outer periphery. An annular seal protrusion having a seal pressure contact margin between the inner peripheral side facing area and the inner peripheral position outside the facing area and the peripheral area of the sealing ball that is press-bonded to the receiving rib above the upper hemisphere. Another feature is that the sealing balls are held by distributing the strips.

  In such a configuration, in addition to the case of the another feature, the seal protrusion on the inner peripheral side of the inner cylinder wall is separated from the inner facing area of the seal protrusion on the outer peripheral side of the inner cylinder wall. In the inner peripheral position, there is a pressure contact allowance in the peripheral area above the upper hemisphere of the sealing ball, and the sealing force is further improved by increasing the receiving force of the sealing ball to the sealing position. The sealing ball is also sealed in the upper hemisphere circumferential area and contributes to the reception at the sealing position. The improvement of the sealing performance by the sealing ball is held in the inner cylinder wall. Do not get in the way of opening and closing the bottle.

  Such a container with a sealing ball as another feature is separately mounted on the mouth of a container made of a resin material and made of a hard material such as glass with an annular sealing protrusion between the mouth. The inside of the inner cylinder wall that extends into the mouth of the container to be mounted from the outlet opening in the ceiling wall is received and held from below with its elastic expansion, and the beverage in the container to be mounted A cap of a container with a sealing ball in which a sealing ball that receives the gas pressure is pressed against an annular receiving rib formed on the inner periphery of the outlet of the inner cylinder wall so as to seal the outlet from the inside. In addition, the screw formed on the inner periphery of the outer cylinder wall extending downward from the outer periphery of the ceiling wall is fitted to the screw formed on the outer periphery of the container mouth so that it can be attached and detached. At the final stage of installation, the outer cylinder wall thread is continuously connected in the circumferential direction. The serrated engagement protrusions formed on the outer periphery of the container mouth are less than the number of serration engagement protrusions formed on the outer periphery of the container. The inner cylinder wall has an detachable structure that engages in the same direction to prevent inadvertent screw loosening, and the inner cylinder wall has an annular seal with a tight fitting margin between the mouth of the container An upper surface of a sealing ball that has a ridge on the outer periphery and is crimped to the receiving rib at a position opposite to the tightly fitting allowance region as viewed in the axial direction of the annular seal ridge on the inner periphery and a position outside the opposite region. Providing a cap for a container with a sealing ball having another feature that the sealing ball is held by allocating an annular sealing ridge having a sealing pressure contact margin between the hemisphere and the surrounding area. is doing.

The annular seal protrusion on the outer periphery of the base part of the inner cylinder wall is a thickened part that is thicker than the tip side by a predetermined length from the base part of the inner cylinder wall, and the annular seal protrusion on the inner periphery of the inner cylinder wall is In a further configuration, which is a local ridge,
Since the outer circumferential seal ridges are thicker than the tip side by a predetermined length from the base of the inner cylinder wall, elasticity is obtained between the inner and outer circumferential seal ridges to the container mouth and sealing balls. In addition to increasing the familiarity and adhesion, the tight fitting width with the container mouth is increased according to the predetermined length, so that the sealing performance with respect to the container mouth is particularly improved, and the reaction force increases. In addition, the sealing performance against the sealing ball by the inner peripheral projecting ridges is enhanced.

The inner cylindrical wall has a tapered shape with a thickness that gradually decreases from the base having an annular sealing ridge on the outer periphery toward the tip, and is pressed against the lower hemisphere area of the sealing ball that is crimped to the receiving rib on the inner periphery. An annular holding rib that is held at the sealing position, and extends from the tip side to the top of the holding rib or in the vicinity thereof in the axial direction from the lower end arrangement inner diameter larger than the diameter of the sealing ball from the lower end part to the upper end part. A guide rib whose array diameter is gradually increased to the top diameter or the upper end array diameter close thereto,
The inner cylinder wall has an outer peripheral seal projection that is a thickened portion at the base, and an annular holding rib is provided on the inner periphery of the tapered portion where the thickness gradually decreases from the base toward the tip. The sealing ball that is pressure-bonded to the lower hemisphere is pressed against and held in the lower hemisphere, and elastic expansion is achieved when the sealing ball is received from the lower side of the inner cylinder wall and held over the holding rib. In addition to facilitating deformation, the receiving sealing balls are smoothly inserted between a plurality of axial guide ribs arranged in the circumferential direction from the lower end having an arrangement inner diameter larger than the diameter of the sealing balls. Accept and guide the ball with a gradually increasing arrangement diameter to the top of the holding rib or its vicinity at the very few contact friction points and expansion points, and the sealing ball against the holding ribs with elastic expansion of the inner cylinder wall Make it easy to get over Can.

In a further configuration, wherein the retaining rib has a bowl-shaped cross section,
The sealing ball enters the sealing position from the lower end side of the inner cylinder wall by using a gentle slope from the top part of the hook-shaped cross section of the holding rib to the tip side and the base side of the inner cylinder wall, and sealing Any slipping from the position to the lower end side of the inner cylinder wall is facilitated by the elastic expansion of the inner cylinder wall even in the case of hard resin.

In the further configuration, the arrangement inner diameter is changed so that the guide rib has a curved shape that is convex inward from the lower end to the upper end.
Although the sealing ball is received in the inner cylinder wall so as to get over the holding rib, initially, the bending moment acts greatly, and the elastic deformation resistance is small at the lower end due to the small elastic deformation resistance due to the tapered shape from the base. With a high rate of relationship, it is easy and smooth to receive the sealing ball into the inner cylinder wall and guide it to the top or near the top of the holding rib without difficulty. After that, the bending moment is small and elastic expansion deformation The resistance is large and the expansion deformation increasing rate on the holding rib side is lowered so that the top of the holding rib can finally be overcome with a sense of resistance and click.

In the further configuration, the inner circumference of the inner cylindrical wall gradually decreases in thickness by forming a convex curved shape from the vicinity of the top of the holding rib to the lower end,
Satisfying a substantially parallel simple shape in which a dead space with the inner periphery of the container mouth on the outer peripheral surface from the base portion to the tip end portion of the inner cylindrical wall is difficult to occur, and a rib guide surface shape due to the rising of the guide rib, The thickness from the base to the tip side can be adjusted, and the rate of increase in thickness on the base side in particular can be increased to give the instantaneous resistance and click feeling more strongly.

The container mouth and cap screw are two or more multi-thread threads, in a further configuration,
Since the multi-thread screw increases the lead amount with respect to the rotation amount in proportion to the number of the threads, the mounting depth to the container mouth is satisfied with less rotation of the cap, and the container side engagement of the cap side engagement protrusion is satisfied. It is possible to reduce the necessary number of ride over the joint protrusion.

In a further configuration, about 3 to 5 engagement protrusions of the mouth of the container are provided.
In order to make the number of engaging projections on the container side smaller than that on the cap side, there are three or more circumferential positions where the cap side engaging projections get over the corresponding container side engaging projections. While being supported stably at evenly spaced positions, within the range of normal screw tightening torque by the capper, it can be smoothly overcome with elastic deformation such as expansion at the container side engagement projection and contraction between them The cap can be mounted with ease in proportion to the small number of container-side engagement protrusions, and the stability can be greatly increased even in proportion to the slight increase in the number of support points by the container-side engagement protrusions. The balance between the difficulty of holding and removing can be easily adjusted, and it is preferable to provide four container-side engagement protrusions. The engagement protrusions on the outer cylindrical wall of the cap are the engagement protrusions on the container mouth. About 5 to 7 times The are suitable for practical use.

In a further configuration, the engagement protrusion of the container mouth is formed on the outer periphery of the container mouth, and the engagement protrusion of the outer cylinder wall of the cap is formed on the inner periphery of the outer cylinder wall of the cap.
After the cap is attached, it is possible to prevent the engaging portion between the cap side engaging protrusion and the container side engaging protrusion from appearing, and it is possible to make it difficult to receive unauthorized external force such as mischief or inadvertent external force.

In a further configuration in which the ceiling wall of the cap has an annular sealing ridge that presses against the top surface of the mouth of the container,
When the cap is attached to the mouth of the container, the sealing ridges on the ceiling wall come into pressure contact with the top surface of the mouth of the container and seal there, so that the sealing performance for the container is improved.

In a further configuration in which the receiving rib of the cap has an arc shape in cross section to receive the sealing ball,
If the receiving rib of the cap has an arc shape in cross section, the sealing ball will be received in an annular line contact state, compared with the case where the pressing force due to gas pressure is concentrated on the linear contact part and received by the surface. It is easy to be crushed, in other words, it is easy to get in close contact with the outer surface of the sealing ball.

  Further objects and features of the present invention will become apparent from the following detailed description and drawings. Each feature of the present invention can be used alone or in combination in various combinations within a possible range.

  According to the container with the sealing ball and the cap used therefor according to the present invention, the number of parts is small, the attachment / detachment is easy to be screwed to the container opening of the cap, and the inner and outer fittings are fitted to the inner and outer peripheries of the container opening A cylindrical container or a hard container such as glass on the ceiling wall, a sealing property utilizing softness to sealing balls, and the circumferential direction on the end side of the outer cylinder wall at the final stage of the screwing Easy to be accompanied by elastic deformation of the outer cylinder wall in a probable facing relationship from the sliding direction with a serrated engagement projection that is continuous with the serration and a smaller number of serration engagement projections around the outside of the mouth of the container When the cap is loosely engaged, the cap is loosened to the loose side of the cap, and the hook is in the direction of catching. Separation A simple and low-cost structure that allows the cap to be removed relatively easily with elastic deformation of the outer cylinder wall by a small amount of catching in the circumferential direction depending on the intentional manual operation on the screw loosening side. Therefore, it is convenient for separation for cap attachment and separation, and is highly reliable against mischief and inadvertent external force.

  Hereinafter, with reference to FIGS. 1-6, the container with the sealing ball which concerns on embodiment of this invention and the cap used therewith are demonstrated, and it uses for an understanding of this invention. The present embodiment is an example embodying the present invention, and does not limit the contents described in the claims of the present invention.

  As shown in FIG. 6, the container with a sealing ball of the present embodiment includes a container 1 made of a hard material such as glass, and an annular seal projection 3 between the mouth 2 of the container 1 and the mouth 2. And a resin cap 5 that is mounted on the ceiling wall 6 of the cap 5, and an inner cylindrical wall 11 that extends into the mouth 2 of the container 1 from the outlet 7 that opens in the ceiling wall 6 of the cap 5. The expansion outlet 7 is received and held from below with expansion and is pressed against an annular receiving rib 12 formed on the inner periphery of the outlet 7 of the inner cylinder wall 11 under the gas pressure of the beverage in the container 1. And a sealing ball 13 made of a hard material such as glass which is sealed from the inside. The cap 5 can be attached and detached by screwing the screw 15 formed on the inner periphery of the outer cylindrical wall 14 extending downward from the outer periphery of the ceiling wall 6 to the screw 16 formed on the outer periphery of the mouth 2 of the container 1. I am trying to attach it to. As a result, the number of parts is less than the combination of the container 1 made of a hard material such as glass and the cap 5 made of one resin member, and the cap 5 is made of resin and soft against the container 1 and the sealing ball. The sealing performance with the container 1 is provided in the inner cylindrical wall 11 extending from the outlet 7 of the ceiling wall 6 into the mouth 2 of the container 1 because of the relationship of mounting the annular sealing projection 3 or the like on the mouth 2. While receiving the sealing ball 13 from the lower side with elastic expansion and pressing and holding the sealing ball 13 on the annular receiving rib 12 on the inner periphery of the outflow port 7, the cap 5 A simple attachment / detachment structure by screwing the screw 15 of the outer cylindrical wall 14 extending downward from the outer peripheral portion of the ceiling wall 6 and the screw 16 of the outer periphery of the mouth 2 of the container 1 is satisfied.

  As a result, a single cap 5 made of a hard resin such as polyethylene or polypropylene can be mounted on a hard container 1 such as a glass bottle as usual using the rough irregularities 31 on the outer surface of the cap 5 and a conventionally known capper. However, the sealing ball 13 is received in the inner cylindrical wall 11 of the cap 5 and pressed by the gas pressure while securing sealing performance with the annular sealing protrusion 3 or the like between the mouth 2 of the container 1. Since the receiving rib 12 receives and holds it in the sealed state, the sealing of the outflow port 7 by the sealing ball 13 can be achieved reliably. In addition, the sealing ball 13 is attached to the container 1 after filling the beverage with the cap 5 held by the inner cylinder wall 11 so that the sealing ball 13 receives a gas pressure to be in a sealed state or is sealed. The stop ball 13 is first inserted and held in the constricted portion 8 as shown in FIG. 6 of the container 1, the cap 5 is attached, and after filling the container 1 with the beverage, the container 1 is inverted. The sealing ball 13 is pushed into the inner cylinder wall 11 by gas pressure and pressed against the receiving rib 12 so as to be in a sealed state, or two kinds of sealing can be performed.

  Further, as in the conventional method, the sealing ball 13 may be dropped into the container 1 through the outlet 7 through the outlet 7, and the dropped sealing ball 13 is received by the constricted portion 8 and immediately above it. When the container 1 is tilted by a pair of left and right inward recesses 9, 9 as shown in FIG. 5 to drink a beverage from the outlet 7, the sealing ball 13 is prevented from rolling toward the outlet 7, and sealed. The balls 13 are prevented from approaching or entering the lower end opening of the inner cylinder wall 11 to prevent the beverage from flowing out.

  In the present embodiment, in particular, in the example shown in FIGS. 1 and 2, it is continuous in the circumferential direction below the screw 15 of the outer cylindrical wall 14 at the final stage of mounting by screwing the cap 5 to the container 1. 3, 4 (c), and 5 (FIG. 5), the number of the serrated engaging protrusions 21 formed in this manner is smaller than that of the outer periphery of the mouth 2 of the container 1. a) Over one or more of the sliding directions indicated by the arrow A in (b), and the direction in which the cap 5 indicated by the arrow B in FIGS. 3, 4 (c), 5 (a) and 5 (b) is hooked. It is set as the attachment / detachment structure which engages so that it may become and may prevent the cap 5 from unintentionally loosening. As a result, in the final stage of mounting by screwing of the cap 5, any of the serrated engaging projections 21 continuous in the circumferential direction on the outer cylinder wall 14 side has fewer saw teeth around the outside of the mouth 2 part of the container 1. As shown in FIG. 5 (b), the sloped portions 21a and 22a indicated by the arrow A with high probability oppose each other in the sliding direction regardless of the variation in the position of the cap 5 at the final stage of screwing as shown in FIG. The outer cylinder wall 14 is easily overcome with elastic deformation such as expansion at a small circumferential position indicated by arrow C and contraction indicated by arrow D therebetween, and suddenly moves toward the screw loosening side indicated by arrow B of the cap 5. The opposite rising portions 21b and 22b are opposed to and engaged with each other so as to be in the hooking direction. Although this engagement is a portion having a small circumferential direction, the hook to the screw loosening side cannot be removed by mischief or an unintentional external force. However, depending on the non-slip operation using the rough unevenness 31 on the screw loosening side B by intentional manual separation such as separation for separation, the steep rising portions 21b and 22b are reduced by the amount that the catching position is small in the circumferential direction. 5B has a slight inclination of, for example, about 10 °, and further, the protrusion of the engagement protrusion 21 has a minute round shape of, for example, about 0.2 mm. The engagement protrusion 21 on the cap 5 side replaces the engagement protrusion 22 on the container 1 side with the amount of the protrusion on the outer cylindrical wall 14 by the amount that the protrusion 22 has a minute round shape of about 0.3 to 0.4 mm, for example. The cap 5 can be removed by moving over in the catching direction B relatively easily with the elastic deformation of the partial expansion and contraction in the circumferential direction. For this purpose, the resin material of the cap 5 is suitable as the polyethylene or polypropylene which is harder than the soft resin material such as elastomer and softer than the container 1. Mounting is easier with a soft resin material, but loosening and removal are likely to occur due to mischief and unauthorized external force with reduced engagement force on the screw loosening side B.

  The container with a sealing ball having such a structure is made of a resin material, and is attached to the mouth 2 of the container 1 made of a hard material such as glass with an annular sealing ridge 3 between the mouth 2 and the like. And receiving and holding the sealing ball 13 from below in the inner cylindrical wall 11 extending into the mouth 2 of the container 1 mounted from the outlet 7 opened in the ceiling wall 6, A sealing ball 13 that receives the gas pressure of the beverage in the container 1 to be attached is pressure-bonded to an annular receiving rib 12 formed on the inner periphery of the outlet 7 of the inner cylinder wall 11 to seal the outlet 7 from the inside. A cap 5 of a container with a sealing ball configured to be formed on the outer periphery of the mouth 2 of the container 1 with a screw 15 formed on the inner periphery of the outer cylindrical wall 14 extending downward from the outer periphery of the ceiling wall 6. In addition to being fitted to the screw 16 so that it can be screwed on and off, In the final stage of mounting, the number of serrated engaging protrusions 21 formed continuously in the circumferential direction below the screw 15 of the outer cylinder wall 14 is less than that formed on the outer periphery of the mouth 2 of the container 1. A plurality of serrated engagement protrusions 22 are moved over one or more in the sliding direction A and engaged with each other so as to be in the hooking direction in the screw loosening direction B of the cap 5 to prevent inadvertent screw loosening of the cap 5. A cap 5 for a container with a sealing ball having a detachable structure is provided.

  According to the container with the sealing ball and the cap 5 of this embodiment, the number of parts is small, the attachment / detachment of the cap 5 to the mouth 2 of the container 1 is easy, and the container 1 of the resin cap 5 The inner and outer cylindrical walls 11 and 14 fitted to the inner and outer peripheries of the mouth 2, or the sealing property using the softness to the hard container 1 such as glass and the sealing ball 13 of the ceiling wall 6, and the screw fitting A serrated engagement projection 21 that is continuous in the circumferential direction on the end side of the outer cylindrical wall 14 and a serrated engagement projection 22 around the outer portion of the mouth 2 of the container 1 that is less than By the easy climbing with elastic deformation of the outer cylindrical wall 14 in the facing relationship from the slipping direction A with a high probability, an engagement relationship in the hooking direction B can be obtained on the screw loosening side of the cap 5, and the hooking is achieved. By mischief and carelessness Although the above-mentioned catch on the screw loosening side does not come off at an external force level, depending on the intentional manual operation on the screw loosening side, such as separation for separation, the above-mentioned part of the outer cylindrical wall 14 is reduced by the amount of the catching part in the circumferential direction. The cap 5 can be removed by splitting it in different directions C and D inside and outside, canceling each other, and overcoming relatively easily with elastic deformation, so that the cap 5 can be attached and separated with a simple and low-cost structure. Therefore, it is convenient for separation, and is highly reliable against mischief and inadvertent external force.

  Further, as shown in the example of FIG. 1 and the example of FIG. 2, the inner cylindrical wall 11 has an inner periphery of an annular seal protrusion 3 having a tight fitting margin a between the base 2 and the mouth 2 of the container 1. The sealing ball 13 is held by having an annular sealing protrusion 25 having a sealing pressure contact c between the sealing ball 13 and the upper hemisphere of the sealing ball 13 pressure-bonded to the receiving rib 12 in the side facing region b. is doing. Thereby, the base part which has the cyclic | annular seal protrusion 3 and 25 on the outer peripheral side and inner peripheral side of the inner cylinder wall 11 is further received in the opening | mouth 2 and the inner cylinder wall 11 of the container 1, and is received by the receiving rib 12. It is sandwiched between the sealing balls 13 that are held in a pressure-tight sealed state, and receives the pressure corresponding to the tight fitting allowance a and the seal pressure contact allowance c without escape, and the mouth 2 of the container 1 and the sealing balls Adhesion to 13, that is, sealing performance can be enhanced. Moreover, the improvement of the sealing performance with respect to the mouth 2 of the container 1 and the sealing ball 13 by the outer peripheral side of the inner cylindrical wall 11 and the sealing ridges 3 and 25 on the inner peripheral side is as follows. The sealing ball 13 is received with high sealing performance at the sealing position by the pressure contact with the inner wall 11, and what is held in the inner cylinder wall 11 does not interfere with the opening and closing of the container 1. . On the contrary, there is a tendency to apply an extra drop external force to the sealing ball 13, but there is no problem if the holding force for the sealing ball 13 on the inner cylinder wall 11 is increased.

  The annular seal ridge 25 in the example of FIG. 1 and the example of FIG. 2 is located at a position away from the inner circumferential side facing area b and the facing area b of the outer circumferential annular sealing ridge 3 on the inner cylindrical wall 11. A sealing pressure contact allowance c is provided between the sealing ball 13 and the peripheral area of the sealing ball 13 that is pressure-bonded to the receiving rib 12 so as to be distributed. As described above, the seal protrusion 25 on the inner peripheral side of the inner cylinder wall 11 is sealed between the inner facing area of the seal protrusion 3 on the outer peripheral side of the inner cylinder wall 11 and the inner peripheral position away from this. The pressure contact allowance c is provided in the peripheral region of the upper hemisphere or more of the ball 13, and the sealing performance with respect to the sealing ball 13 can be further enhanced without obstructing the opening and closing of the sealing by the sealing ball 13.

  Further, as shown in the example of FIG. 1 and the example of FIG. 2, the annular seal protrusion 3 on the outer periphery of the base portion of the inner cylindrical wall 11 is thickened from the base portion of the inner cylindrical wall 11 by a predetermined length from the tip side. The annular seal projection 25 on the inner periphery of the inner cylinder wall 11 is a local projection. As described above, since the outer circumferential seal ridge 3 is a thickened portion having a predetermined length from the base portion of the inner cylindrical wall 11, the inner and outer circumferential seal ridges as described above are thicker than the distal end side. 3 and 25, since elasticity is obtained and the familiarity and adhesion to the mouth 2 and the sealing ball 13 of the container 1 can be enhanced, the tight fitting area b with the mouth 2 of the container 1 is increased. In addition to particularly improving the sealing performance with respect to the mouth 2 of the container 1, the sealing performance with respect to the sealing ball 13 is also improved.

  Further, as shown in the example of FIG. 1 and the example of FIG. 2, the inner cylindrical wall 11 has a tapered shape in which the thickness gradually decreases from the base portion having the annular seal protrusion 25 on the outer periphery toward the tip, and on the inner periphery. The annular holding rib 27 that presses against the lower hemisphere of the sealing ball 13 that is pressure-bonded to the receiving rib 12 and holds it at the sealing position, and the holding rib 27 from the front end side of the inner cylinder wall 11 in the example of FIG. 2 or near the top of the holding rib 27 shown in the example of FIG. 2, extending from the lower end to the upper end in the axial direction, from the lower end arrangement inner diameter larger than the diameter of the sealing ball 13 to the top diameter of the holding rib 27 or A guide rib 28 having an array diameter F gradually increasing to an upper end section array diameter close thereto is formed. The inner cylinder wall 11 has an outer peripheral side seal projection 3 as a thickened portion at the base, and a holding rib 27 is provided on the inner periphery of the tapered portion where the thickness gradually decreases from the base toward the tip. The sealing ball 13 that is pressure-bonded to the rib 12 is held in pressure contact with the lower hemisphere circumferential region, and the sealing ball 13 is received from below the inner cylindrical wall 11 and is held over the holding rib 27. In addition to facilitating elastic expansion deformation corresponding to the interference allowance G, the sealing balls 13 to be received are interposed between a plurality of axial guide ribs 28 arranged in the circumferential direction. The inner cylinder F is smoothly received from the lower end having an array inner diameter F larger than the diameter, and is guided with a gradual increase in the array inner diameter F to the top of the holding rib 27 or the vicinity thereof at an extremely small contact friction portion or expansion portion. Wall 11 elastic It is possible to make it easier for the sealing ball 13 to get over the holding rib 27 with tension, and the holding force of the holding rib 27 to the sealing position with respect to the sealing ball 13 depends on the size of the interference margin G and the inner cylinder wall. 11 can be easily adjusted according to the degree of taper.

  If the holding rib 27 has a bowl-shaped cross section as shown in the example of FIG. 1 and FIG. 2, the sealing ball 13 has a bowl-shaped section of the holding rib 27 on the tip side of the inner cylinder wall 11. In addition, by using a gentle slope formed on the base side, the upper end of the guide rib 28 enters the sealing position from the lower end side of the inner cylindrical wall 11 when the upper end does not reach the top of the holding rib 27, and from the sealing position. Any slipping out to the lower end side of the inner cylindrical wall 11 is facilitated with elastic expansion of the inner cylindrical wall 11. In addition, since the inner diameter of the guide ribs 28 changes so that the guide ribs 28 have an inwardly convex curved shape from the lower end portion to the upper end portion thereof, the sealing balls 13 can be passed over the holding ribs 27 so that the sealing balls 13 can get over the holding ribs 27. However, in the initial stage, the expansion bending moment with the base portion of the inner cylindrical wall 11 as a base point is large, the elastic deformation resistance due to the tapered shape from the base portion is small, and the rate of increase of the elastic expansion deformation at the lower end portion The sealing ball 13 is guided without difficulty to the top of the holding rib 27 or near the top, and thereafter, the expansion bending moment is small, the elastic expansion deformation resistance is large, and the elastic expansion deformation on the holding rib 27 side is large. The increase rate is lowered so that the top of the holding rib 27 can finally be overcome with a sense of resistance and click. Therefore, it is easy to push the sealing ball 13 into the inner cylinder wall 11 and hold it by hand operation, and it is easy to obtain a signal of completion of holding by the final click feeling and finish the operation with peace of mind.

  Further, as shown in the example of FIG. 1 and the example of FIG. 2, the inner periphery of the lower side of the holding rib 27 of the inner cylindrical wall 11 has a curved shape protruding outward from the vicinity of the top of the holding rib 27 to the lower end. The thickness is gradually decreasing. Thereby, the inner periphery of the mouth 2 of the container 1 on the outer peripheral surface from the base portion to the distal end portion of the inner cylindrical wall 11 and the substantially parallel simple shape that hardly causes dead space and the rising guide surface shape of the guide rib 28 are satisfied. The thickness adjustment from the base portion of the inner cylindrical wall 11 to the tip side can be easily performed, and the thickness increase rate on the base portion side can be increased to give the instantaneous resistance and click feeling more strongly.

  In addition, each of the mouth 2 of the container 1 and the screws 16 and 15 of the cap 5 are two or more multiple threads, and the multiple threads increase the lead amount with respect to the rotation amount in proportion to the number of the threads. 5 can satisfy the mounting depth of the container 1 to the mouth 2 with less rotation, and the number of necessary protrusions of the engagement protrusion 21 on the cap 5 side with respect to the engagement protrusion 22 on the container 1 side can be reduced. Mounting is further facilitated without lowering the safety against loosening or removal of the screw 5. Here, when about three to five engagement protrusions 21 of the mouth 2 of the container 1 are provided, the number of engagement protrusions 22 on the container 1 side is three or more to make the number smaller than the cap 5 side. As a result, the circumferential position where the engagement protrusion 21 on the cap 5 side gets over the corresponding engagement protrusion 22 on the container 1 side is stably supported at three or more equidistant positions, while the engagement position on the container 1 side. Easily proportional to the small number of engagement protrusions 22 on the container 1 side, which can be smoothly overcome with the elastic deformation of the aforementioned protrusions 22 in the C direction and the contraction in the D direction between them. The number of the engagement protrusions 22 on the container 1 side is increased by a few, and the safety against mischief of the cap 5 and unauthorized external force is increased in proportion thereto. From the balance of these functions, the number of the engagement protrusions 22 on the container 1 side is preferably four, and the engagement protrusion 21 of the outer cylindrical wall 14 of the cap 5 is five times the engagement protrusion 22 of the mouth 2 of the container 1. It is suitable for practical use to be provided about 7 times. More preferably, as an example of the example of FIG. 1 and the example of FIG. 2, there are four engagement protrusions 22 for two engagement protrusions 22.

  Further, the engagement protrusion 22 of the mouth 2 of the container 1 is formed on the outer periphery of the mouth 2 of the container 1, and the engagement protrusion 21 of the outer cylindrical wall 14 of the cap 5 is formed on the inner periphery thereof. Thus, after the cap 5 is mounted, the engaging portion between the engaging protrusion 21 on the cap 5 side and the engaging protrusion 22 on the container 1 side should not be seen as shown in the example of FIG. 1 and FIG. It is possible to make it difficult to receive unauthorized external force such as mischief or inadvertent external force. Furthermore, in the example of FIG. 1 and the example of FIG. 2, the ceiling wall 6 of the cap 5 has an annular seal protrusion 29 that presses against the top surface of the mouth 2 of the container 1, and the cap 5 is the mouth of the container 1. 2, the sealing protrusion 29 of the ceiling wall 6 is pressed against the top surface of the mouth 2 of the container 1 and sealed there, so that the sealing performance for the container 1 is improved. When the receiving rib 12 of the cap 5 has a circular arc shape as shown in the example of FIG. 1 and the example of FIG. 2 to receive the sealing ball 13, the receiving rib 12 has an annular line. The receiving rib 12 is easily crushed as compared with the case where the pressing force due to the gas pressure is concentrated on the annular line contact portion and is received by the surface, in other words, the outer surface of the sealing ball 13 is better. It becomes easy to adhere and adhere, and the sealing performance is improved.
