Description

  The present invention relates to containers and in particular containers for supplying beverages to consumers. The present invention has particular utility for the storage and supply of carbonated and other sparkling beverages and non-carbonated beverages and other types of beverages or other materials.

  Known beverage containers comprise a glass bottle with a cap formed of metal. The cap is pressed over the edge around the bottle opening. While very successful, this closure type has the disadvantage of requiring a tool, such as a bottle opener, to pry the cap off the bottle.

  Another known container type comprises a plastic bottle with a plastic screw cap. In many cases, these caps can be attached by press-fitting into the bottle (rather than being screwed), but their removal requires unscrewing of the caps, often rotating the caps by more than 360 ° There is a need. This type of occlusion also requires having threading on the outside of the neck of the bottle.

  The present invention seeks to provide an alternative to the prior art.

  In the first embodiment of the present invention, a container body having an opening, wherein the opening defines an axis that penetrates the container body, and the container body, A cap having an upper part and a skirt part depending from the upper part, wherein the container body has an edge part projecting outward around the opening part, and the cap has an inner periphery of the skirt part. A member that surrounds and protrudes inward, and the edge has a plurality of spaced recesses for receiving the member when the cap is press-fitted into the container body, The cap has an outer periphery until the member snaps into each of the recesses of the edge when the cap presses the edge inward as the portion carrying the member bends outward. Almost deformed into a polygonal shape Made, the member and the recess, the container rotation of the cap for subsequent of the container body forms a shape as to enter into the cap to the edge is provided.

  In the second embodiment of the present invention, a container body provided with an opening, wherein the opening defines an axis that penetrates the container body, and the container body, in order to close the opening, A cap having an upper part and a skirt part depending from the upper part, wherein the container body has an edge part projecting outward around the opening part, and the cap has an inner periphery of the skirt part. A member that surrounds and protrudes inward, and the edge has a plurality of spaced recesses for receiving the member when the cap is press-fitted into the container body, The cap and recess are subsequently moved to the open position as the member is moved out of each of the recesses on the outer surface of the edge as the cap rotates relative to the container body in the release direction. Moving And until the container in the shape as the outer periphery of the skirt portion is bent substantially polygonal shape is provided.

  In another aspect of the invention, a container body used to provide such a container and a cap used to provide such a container are provided.

  One object of the present invention is to provide a container having the aesthetics of a crown and the convenience of a screw cap.

  Another object of the present invention is to provide a plastic cap that uses less material and is therefore lighter than conventional plastic screw caps.

  Preferred or optimal features of the invention will become apparent from the following description and the dependent claims.

  The invention will now be further described with reference to the accompanying drawings, which are by way of example only.

  FIG.1 and FIG.2 is a bottle-shaped container, Comprising: The container provided with the container main body 1 and the cap 2 for obstruct | occluding the opening part 3 in the upper end part of a container main body is shown. The opening mainly has a diameter of about 28 mm.

  FIG. 2 is an enlarged view of the neck portion of the container body 1 and the closing cap 2 for fitting to the container body 1. The opening 3 at the upper end of the container body defines an axis A passing therethrough.

  The container body 1 has an outward projecting edge 4 around the opening 3. A plurality (4 in the illustrated embodiment) of spaced recesses 5 are provided in the lower portion of the edge 4. Each of these recesses 5 is defined by an upper surface 5A and two end surfaces 5B and 5C. The upper portion 4A of the edge 4 has a smooth and curved outer shape, and the outer diameter thereof decreases at a position toward the upper surface 4B of the edge 4.

  The cap 2 comprises an upper part 6 from which a skirt part 7 which is sufficiently circular is suspended. A plurality (4 in the illustrated embodiment) of spaced apart inner projecting members 8 (see FIG. 3) are provided around the inner peripheral surface of the skirt portion 7. As will be described later, when the cap 2 is fitted into the container body 1, the member 8 engages with each of the recesses 5.

  To attach the cap 2 to the container body 1, the cap 2 is pressed against the edge 4, and the member 8 engages the upper surface 4B or its curved surface 4A. When the cap 2 is pressed downward, the member 8 passes through the curved surface 4A so that it passes through this surface until it reaches the bottom of the edge and snaps into each of the recesses. Moved out of the direction.

  The cap 2 is deformed into a substantially polygonal shape (a rounded quadrilateral shape in the illustrated embodiment) so that the member 8 is pushed radially outward. This can be attributed to the length of the circumferential gap between the adjacent members 8 and the elasticity of the skirt portion 7. The inner surface of the skirt 7 in the region between the members 8 is inclined toward the opening end of the cap 2, and the diameter of the opening of the cap increases toward the opening end. This also reduces the wall thickness of the skirt 7 towards the open end of the cap 2 and increases the elastic flexibility of the cap in this region. Further, the inclination of the inner surface is a snug fit between the inner surface of the skirt portion 7 and the inwardly tapered outer surface of the upper portion 4A of the edge when the cap 2 is fitted to the container body 1. Help to ensure.

  As shown, the gap between the members 8 allows the cap skirt 7 to be bent into a polygonal shape. Preferably, the length of each member 8 in the circumferential direction is shorter than the circumferential gap between adjacent members. In the illustrated embodiment, the cap has an inner diameter on the order of 28 mm, each member 8 has a circumferential length on the order of 7-8 mm (in their maximum dimensions), and the circumferential direction between adjacent members. The gap is about 13 to 14 mm. The depth of the skirt portion 7 (from the upper portion 6 to the opening end of the cap) is typically about 5 to 6 mm (compared to the depth of about 10 mm in a conventional 28 mm diameter screw cap).

Each member 8 has an upper surface 8A, a lower surface 8B, end surfaces 8C and 8D, and an inward surface 8E.
The lower surface 8B is inclined upward in the radial direction, that is, upwardly inclined toward the axis of the cap. When the edge is pressed against the container body, the lower surface 8B engages with the curved surface 4A of the edge. Then, the members 8 are pushed radially outward so that they get over the surface 4A toward the lower part of the edge 4. In the circumferential direction, the lower surface 8B is substantially horizontal.

  As the cap 2 is pressed against the container body 1, the member 8 can ride over the outer surface of the edge 4 until they reach the recess 5 so that the skirt is bent into a generally polygonal shape. Then, the elasticity of the skirt 7 causes it to snap fit with the recess 5 as the substantially circular return member moves radially inwardly below the upper surface 5A of the recess 5.

  The upper surface 8A of the member is engaged with the upper surface 5A of the recess. As shown in FIGS. 2 and 3, the upper surface 5 </ b> A of the recess is inclined in the circumferential direction, and the cap 2 is in a fastening direction with respect to the container main body 1 (clockwise in a top view in the illustrated embodiment). When rotating, the cap 2 is fastened to the container body 1. As a result, the inner surface of the upper part 6 of the cap and / or the inner surface of the skirt 7 thereof is brought into sealing engagement with the surfaces 4A and / or 4B of the edge 4.

  The upper surface 8A of the member 8 is substantially horizontal in the radial direction, but is inclined in the circumferential direction in order to increase the fastening.

  The end surface 5B of the recess 5 is provided with a stop portion for preventing the cap 2 from being excessively fastened. Engagement of the end surface 8D of each protrusion with the end surface 5B of each recess prevents further movement of the cap 2 in the fastening direction with respect to the container body 1. The end faces 8D and 5B are both substantially vertical and both extend substantially radially toward the axis A.

  In order to open the cap 2, the cap 2 is rotated with respect to the container body 1 in a loosening direction (counterclockwise in top view in the illustrated embodiment). Initially, this moves each member 8 along the respective recess from the end face 5B toward the end face 5C. Due to the inclination of the upper surface 5A of the recess and / or the upper surface 8A of the member 8, this makes it possible to move the cap at least a short distance (for example 1-2 mm) away from the container body 1 in the direction of the axis A. . This releases the seal between the cap 2 and the container body and allows for ventilation of the container body (for example by a carbonated beverage) in which excess pressure therein is released. However, the cap 2 is still held in the container body 1 by the engagement of the member 8 in the recess 5.

  Until further rotation of the cap 2 in the release direction, the end face 8C of each member engages the end face 5C of each recess. Since these surfaces are both substantially vertical but inclined, the cap 2 rotates, the member 8 moves over the end face 5C, and the member 8 reaches the outer surface of the edge 4 in the region 4C between the adjacent recesses 5. It is moved radially outward (since the skirt 7 is again substantially polygonal).

  As described above, since the outer surface of the edge portion 4 is inclined, the diameter of the edge portion 4 decreases toward the open end of the container body 1. Due to its elasticity, the skirt 7 of the cap tries to return to a substantially circular shape, and the member 8 passes upward avoiding the outer surface of the edge 4 because they make the skirt 7 more circular. It can move radially inward. Thereby, the cap 2 is easily raised to the edge 4, which moves further away from the container body 1 in the direction of the axis A. This also reduces the risk that the member 8 will unexpectedly slip back (clockwise) and re-engage with the recess 5 or slip (counter-clockwise) and engage with the next recess 5. To assist.

  If it is desired to refit the cap 2 to the container body 1, this means that the cap 2 is pushed back to the edge 4 (using a downward force along the axis A) and the cap 2 is fastened to the edge. This is possible by rotating clockwise.

  From the above description, each of the members 8 thereby tilts upward in the radial direction but is substantially horizontal in the circumferential direction, the upper surface 8A that is substantially horizontal in the radial direction but tilted in the circumferential direction, and one of the members 8 has a diameter. It will be understood that it has two end faces 8C, 8D that are laterally inclined in the direction and both are substantially perpendicular in the radial direction. These four surfaces are generally triangular as shown in FIG. 3 and define the boundaries of the inwardly facing surface 8E. In use, the surface 8E is located in the recess 5 near the outer surface of the container 1.

  4 to 8 show a container according to the second embodiment of the present invention. This is similar to the container shown in FIGS. 1-3, but has a first type of tamper evident feature. The parts of the container in FIGS. 4 to 8 are identical to those in FIGS. 1 to 3 and are labeled with the same but increased by ten.

  The cap 12 is similar to the cap 2, but has a tamper band 10 depending from the skirt portion 17. The tamper band 10 is connected to the skirt portion 17 by a plurality of (16 in the illustrated embodiment) small weakening bridges 10A and a plurality (4 in the illustrated embodiment) connecting bands 10B. A plurality (4 in the illustrated embodiment) of projecting portions 10 </ b> C project radially inward from the inner surface of the tamper band 10.

  When the cap 12 is pressed against the container 11 in the direction D1 shown in FIG. 5, the skirt 17 is engaged with the recess 15 as the member 18 moves over the edge 14 as in the first embodiment. Bends into a nearly polygonal shape. Further, when the cap 12 is pressed against the container body 11, the protruding portion 10C gets over the edge portion 14, and once the cap 12 is rotated in the direction D2 shown in FIG. It is disposed under the lower surface 14D of the portion 14C of the edge portion 14.

  Since the lower surface 14D of the edge portion 14 is inclined in the circumferential direction, when the cap 12 rotates in the direction D3 (release direction) as shown in FIG. 6, the protruding portion 10C is as shown by the arrow D4 in FIG. Moved downward. This causes the weakened bridge 10A to break so that the rest of the cap 12 is immovable downwards (so that it engages the top surface of the edge 14).

  Since the protrusion 10C is positioned on the band 10, the member 18 once moves to engage with the end face 15C along the recess 15 (over the skirt portion 27 in a substantially polygonal shape) and overcomes them. When reaching the outer surface of the edge portion 14, the protruding portion 10C moves to the adjacent recess 15 along the lower surface 14D. The cap 12 is removable in the direction D5 as shown in FIG. 7 (along with the tamper band 10 connected thereto by the connecting band 10B), and is separated from the container body 11 as shown in FIG.

  9 to 13 show a container according to a third embodiment of the present invention. This is similar to the container shown in FIGS. 1 to 3, but has a second type of tamper-evident prevention function. The parts of the container in FIGS. 9 to 13 are identical to those in FIGS. 1 to 3 and are labeled with the same but increased by 20.

  The cap 22 is the same as the cap 2, but has a tamper band 20 depending from the skirt portion 27. The tamper band 20 is connected to the skirt portion 17 by a plurality (20 in the illustrated embodiment) of weakening bridges 20A and a single connecting band 20B. Since the lower part 20D of the tamper band is bent inward (as indicated by the arrow B in FIG. 10), the upwardly facing end 20E has its inner circle radially inward from the inner surface of the tamper band 20. It protrudes around the entire circumference.

  When the cap 22 is pressed against the container body 21 in the direction D1 shown in FIG. 11, the skirt portion until the member 28 is engaged with the recess 25 as in the first embodiment as the member 28 goes over the edge 24. 27 is bent. Further, when the cap 22 is pressed against the container body 21 and snap-fitted under the lower surface 24D of the edge 24, the end 20E of the tamper band 20 gets over the edge 24. Although the lower surface 24D is shown as being inclined in the circumferential direction in FIGS. 9 to 13, in the present embodiment, these may be horizontal as well. The cap 22 is rotated in the direction D2 shown in FIG. 11 and fastened to the container 11 as in the first embodiment.

  When the cap 22 is rotated in the releasing direction, the member 28 gets over the end face 25C of the recess 25 (while bending the skirt portion 27 into a substantially polygonal shape), and the upper portion 26 and the skirt portion 27 are the same as those in the first embodiment. The tamper band 20 is prevented from becoming so by the engagement of the end 20E of the portion 20D under the lower surface 24D of the edge 24. As a result, the weakening bridge 20A breaks, but the tamper band 20 remains connected to the remainder of the cap 22 by the connecting band 20B. The tamper band 20 can slide down the outer surface of the container body 21 in the direction D6 shown in FIG. 12, while the remaining portion of the cap rotates away from the opening 23 as indicated by an arrow C.

  The circular ridge 21A is provided around the neck of the container body 21, and the tamper band 20 can be lowered through the circular ridge 21A, and the end 20E of the upright portion 20D passes through the ridge 21A and below it. The tamper band is held in this position (as shown in FIG. 12). This prevents the tamper band from sliding back toward the opening 23 when the container body is tilted to pour a beverage from the container body. However, since the connecting portion 20B has a sufficient length, the cap 22 can be pushed down again over the edge 24 (and tightened tightly if desired) (as shown in FIG. 13). Can be re-fitted to.

  14 to 19 show a container in the fourth embodiment of the present invention. This is similar to the container shown in FIGS. 1 to 3, but has a third type of tamper-evident prevention function. The parts of the container in FIGS. 14 to 19 are identical to the parts in FIGS. 1 to 3 and are labeled with the same but increased by 30. The container body in this embodiment is suitable for being formed of glass (similarly, it may be formed of plastic).

  The cap 32 is the same as the cap 2, but has a tamper band 30 depending on the skirt portion 37. The tamper band 30 is connected to the skirt portion 37 by a plurality (8 in the illustrated embodiment) of weakening bridges 30A and a plurality (4 in the illustrated embodiment) of connecting bands 30B. A plurality (8 in the illustrated embodiment) of protruding portions 30 </ b> C protrude radially inward from the inner surface of the tamper band 30.

  The container main body 31 is the same as the container main body in the first embodiment, but further includes a plurality (8 in the illustrated embodiment) of the protruding portion 31A and the lower portion of the edge portion 34 protruding outward. A projecting portion 31 </ b> A projecting radially outward from the outer wall portion of the main body 31 at a position separated from the portion 34.

  When the cap 32 is pressed against the container body 31, as the member 38 gets over the edge 34 until the inwardly projecting member 38 (not shown) engages with the recess 35 as in the first embodiment, The skirt portion 37 bends in a substantially polygonal shape. Further, when the cap 32 is pressed against the container main body 31, the protrusion 30C gets over the edge 34, and once the cap 32 is rotated in the fastening direction, the protrusion 30C is brought to the height of the protrusion 31A described above. Be positioned.

  When the cap 32 is rotated in the release direction, the protruding portion 30A of the cap 32 engages with the protruding portion 31A of the container body 31, and stops the rotation of the tamper band 30 with respect to the container body 31. Accordingly, further rotation of the cap 32 in the release direction causes the weakening bridge 30A to break and the member 38 (not shown) of the cap 32 exits from the recess 35 in the edge 34 of the container body 31. The coupling band 30B is folded into a bellows shape as shown in FIG. 16 during this relative rotation. The cap 32 can be detached from the container body 31. The tamper band 30 remains connected to the cap 32 by the connecting band 30B, and is thereby removed together with the cap 32 as shown in FIGS.

  19 to 21 show a container according to a fifth embodiment of the present invention. This is similar to the container shown in FIGS. 1 to 3, but has a fourth type of tamper-evident prevention function. The parts of the container in FIGS. 19 to 21 are identical to those in FIGS. 1 to 3 and are labeled with the same but increased by 40.

  The cap 42 is similar to the cap 2, but has a tamper band 40 depending from the skirt portion 47. The tamper band 40 is connected to the skirt portion 47 by a plurality of (8 in the illustrated embodiment) small weakening bridges 40A. A plurality (4 in the illustrated embodiment) of protruding portions 40C protrude radially inward from the inner surface of the tamper band 40.

  The container main body 41 is the same as the container main body in the first embodiment, but further includes a plurality (two in the illustrated embodiment) of the protruding portions 41A and the edge 44 protruding outward (FIGS. 19 and 21). A protrusion 41A that protrudes radially outward from the outer wall of the main body 41 at a position below the edge 44. In the present embodiment, the groove 41B is provided on the wall of the container for gripping by the blow molding tool. This groove part divides each protrusion 41A into two parts.

  When the cap 42 is pressed against the container body 41, the skirt portion until an inwardly projecting member (not shown) rides over the edge 44 until the member 48 engages the recess 45 as in the first embodiment. 47 is bent. Further, when the cap 42 is pressed against the container body 41, the protruding portion 40C gets over the edge portion 44, and once the cap 42 is rotated in the fastening direction, the protruding portion 40C has the height of the above-described protruding portion 41A. Located in.

  When the cap 42 is rotated in the release direction, the protruding portion 40C of the cap 42 engages with the protruding portion 41A of the container body 41, and stops the rotation of the tamper band 40 with respect to the container body 41. Thus, further rotation of the cap 42 in the release direction causes the weakening bridge 40A to break and the member 48 (not shown) of the cap 42 exits from the recess 45 in the edge 44 of the container body 41. The cap 42 can be removed from the container body 41.

  When the weakening bridge 40A is broken, the tamper band 40 is separated from the cap 42, and is lowered from the neck of the container body 41 to a position where the outer diameter of the container 41 is the same as the inner diameter of the band 40 as shown in FIG. drop down. Alternatively, the band 40 is lifted from the neck of the container 41 independently of the cap 42.

  In each of the described embodiments, the cap may be formed of a plastic material, for example by injection molding. The container body may likewise be formed of a plastic material, for example by injection molding and blow molding. However, the container body may be formed of glass as well.

  It is preferable that the diameter of the opening part of a container main body exists in the range of 25-30 mm so that it may be generally used for a bottle, for example. However, the present invention may also be used with containers having other sized openings including diameters up to 50 mm and wide mouth openings (generally having a diameter in the range of 50-80 mm).

  In the described embodiment, the cap is provided with four inwardly projecting members for engaging the four recesses at the edge of the container body. Other embodiments may use more or fewer members and recesses. Preferred embodiments have 3, 4 or 5 members and recesses. For example, four members (and recesses) may be used in a container opening having a diameter in the range of 25-35 mm, and five may be used in a container having an opening in the range of 35-45 mm. Well, and 6 may be used for openings in the 45-55 mm range. More members (and recesses) are used for a given diameter, but a larger number of caps skirts (although many members each require an inward projection by a smaller distance) Will be less flexible

  The container is two separate camming actions to deform the cap skirt into a substantially polygonal shape, one when the cap fits into the container body and the other when the cap is removed therefrom. Two cam action is adopted. In the first case, the inwardly projecting member in the cap is pushed radially outward across the entire edge as the cap is press fit into the container body. In the second case, the member is pushed radially outward by the ramp at the end of the edge recess as the cap rotates relative to the container body.

  As a result, the container having the above characteristics can be press-fitted into the container body and is opened by a relatively small rotational movement (depending on the number of protruding members used). With four members, the cap needs to rotate less than 90 ° to release it from the container body. Furthermore, it is not necessary to provide a male screw at the neck of the container body. For this reason, the neck has a smooth and aesthetically attractive appearance, such as the neck of a conventional glass bottle.

  The cap is preferably made of a plastic material, so that it can be pressed into the container, the container need not have a threaded part outside the neck, and the cap can be removed with a relatively small rotational movement. Optionally, the cap may be configured to be refit by the user. Thereby, the cap integrates the advantages of the traditional crown closure and the conventional thread cap and bottle neck. In addition, the cap uses significantly less material than conventional plastic screw caps, saving material costs and weight.
