Definitions

  • the present invention relates to a bottle cap, and more specifically to a bottle cap for sealing the opening of bottle that accommodates liquids such as medical liquid, drinking water, liquor and other liquids.
  • bottle caps of various shapes are adopted as a means of opening and closing bottles accommodating drinking water or fresh water to prevent leakage or deterioration of the accommodated contents during distribution after input of the contents.
  • Bottle caps that are generally divided into a screw type bottle cap which uses an opening and closing method by screwing and an insert type bottle cap which uses an opening and closing method by insert means.
  • the screw type bottle cap is of a configuration in which a bottle cap having internal threads formed on the inner circumference is assembled to the opening of bottle having external threads formed on the outer circumference. Therefore, sealability is high, so it is used as a bottle cap of the bottle for accommodating the contents requiring air tightness such as carbonated beverages or beer.
  • a bottle cap is of a configuration assembled to the external threads formed on the outer circumference of the bottle, so not only a considerable force is needed to open, but also the bottle cap should be turned repeatedly to open the bottle, so it has an inconvenience that it is difficult to open it at once.
  • the insert type bottle cap is a configuration of fitting the bottle cap into the inner circumference of the neck of bottle, so it has an advantage that it is easy to open and close the bottle cap. But such a bottle cap is not only opened by a weak external force but also the sealability of the bottle cap is low, so it has a problem that it is difficult to adopt it as the bottle cap of the bottle for accommodating the contents that require air tightness such as carbonated beverages or beer, in particular.
  • the present invention has an object to provide a bottle cap, which has high enough sealability to be adopted even for the bottle accommodating carbonated beverages, etc. and can be opened and closed by a simple action, and is environmentally friendly and low in manufacturing costs.

  • a curved portion 14 b with a curve-shape is formed in the portion in the first cap 10 where the sidewall lower section of the depressed portion 14 is connected with the bottom surface thereof, the outer wall lower section of the depressed portion 14 can easily slip out of the opening of the bottle when the bottle cap is opened.
  • the cut-and-open portion 30 of the first cap 10 having the second cap 20 assembled thereto is used to strip the first cap upward obliquely from the opening of the bottle so as to have the opening of the bottle opened.
  • the first cap 10 is fitted in close contact with the opening of the bottle by the second cap 20 , it is of course possible to open the bottle by stripping the first cap 10 from the opening of the bottle using the cut-and-open portion 30 after stripping the second cap 20 first.
  • FIGS. 20 to 22 illustrate modified examples of the bottle caps according to the embodiments illustrated in FIGS. 10 to 12 .
  • FIG. 20 is a bottom view showing an air passage 14 c formed in the first cap 10
  • FIG. 21 is a sectional view showing the air passage 14 c formed in the first cap 10
  • FIG. 22 is an enlarged view showing “B” portion of FIG. 21 .
  • an air passage 14 c of a concave slot shape that connects the lower end of the depressed portion 14 and the bottom thereof so that air inside the bottle can be discharged.
  • an air passage 14 c one or more air passages having a uniform width of passage and formed in a straight line shape are arranged radially.
  • an opening sound is generated when carbon dioxide gas inside the bottle is discharged, and the user can feel the discharge of carbon dioxide gas by their finger when it is discharged. Accordingly, the user is able to judge whether the bottle cap is opened or not, and at the same time, he can know his opening is the first opening and also can have a refreshing feeling by dint of the opening sound. And in the case of beverages or beer containing carbon dioxide gas, the content could overflow at the time of initial opening, but since the inside air is slowly discharged by dint of such an air passage 14 c , overflow of content can be prevented.
  • the opening location of the bottle cap is limited to the location nearest to the cut-and-open portion 30 . Therefore, the air inside the bottle is discharged out through the air passage 14 c of this portion. So in the present embodiment, it would not matter even if only one air passage 14 c is formed in the nearest location of the opening knob 34 . However, if such an air passage 14 c is applied to the bottle cap of the first embodiment, the opening location of the bottle cap is not specifically limited but can be various, so it is preferable to arrange a plurality of air passages 14 c in the curved portion 14 b in a radial shape.
  • an enlarged type air passage 14 d in which the width of air passage is formed wider in the lower section than in the bottom of the depressed portion, may be formed as shown in FIG. 23 .
  • the upper portion of the air passage 14 d is expanded, so that even in the case where the location of opening and the location of air passage 14 d do not match accurately, discharge of the air in the bottle becomes possible by the expanded portion of the air passage 14 d.
  • FIG. 24 and FIG. 25 illustrate another modified example of the bottle cap according to the present embodiment.
  • a downward elongated skirt portion 14 e is formed on the circumference of the bottom end outer circumference section of the sidewall of the depressed portion 14 .
  • This skirt portion 14 e comes into close contact with the inner circumference of the neck of the bottle. Accordingly, when the gas pressure of the content such as carbonated beverages or beer in particular acts upward toward the opening of the bottle, the skirt portion 14 e is expanded outward by the pressure to come into close contact with the inner circumference of the neck of the bottle 100 . Therefore, the sealability between the inner circumference of the neck of the bottle 100 and the depressed portion 14 of the first cap 10 is further improved.
  • Such a skirt portion 14 e can be applied along with the modified example as shown in FIGS. 20 to 22 , and can be applied to the bottle cap of not only the second embodiment but also the first embodiment.
  • FIG. 26 and FIG. 27 are sectional views showing modified examples of the bottle cap circumference portion according to the present invention.
  • the lower end of the circumference portion 11 of the first cap 10 is depressed, so that it is formed thinner than the other portion of the circumference portion 11 with the thickness decreasing.
  • the lower end of the circumference portion 11 is depressed, so it can be formed into a stepped portion 11 a as shown in FIG. 26 , or into a curved portion 11 b as shown in FIG. 27 .
  • the bottle cap Since the first cap 10 has the outside of the lower end of the circumference portion 11 depressed, the bottle cap is not stripped but slipped even if the carriage box or a finger is caught on the circumference portion 11 of the bottle cap 11 in the case that the bottle is transported or carried with the bottle cap not opened.
  • the circumference of the bottom end portion depressed like this can prevent unintended stripping of the bottle cap when the bottle is transported or carried. Namely, the bottle cap having the depressed circumference portion 11 formed can be stripped only by opening the cut-and-open portion 30 , so the function of preventing unintended breakaway of the bottle cap during transport or carrying is further improved.
  • the bottle cap is provided with the cut-and-open portion 30 , so it is preferable that the bottle cap is not opened by any other factor except the opening attempt by the cut-and-open portion 30 .
  • the circumference portion 11 having the bottom section depressed like this plays a role of preventing the bottle cap from being easily opened even during the opening attempt by an abnormal method using another tool or fingernail.
  • Such a depressed circumference portion 11 can be applied to the bottle cap of not only the second embodiment but also the first embodiment.
  • FIG. 28 is a side view of the bottle cap according to the second embodiment, and for the sake of convenience of description and illustration, the cut-and-open portion 30 is shown with dotted lines.
  • the circumference portion 11 of the first cap has a depressed portion 36 formed, in which the lower portion is cut to be curved upward in the portion where the opening knob 34 is formed.
  • the portion of the circumference portion 11 where the opening knob 34 is formed is formed identically with other circumference portion 11 , the user's finger inserting operation is not made from the state of FIG. 16 to the state of FIG. 17 when opening the bottle cap but is caught by the circumference portion 11 to make the opening operation inconvenient.
  • a method of cutting out the portion of the circumference portion 11 where the opening knob 34 is formed may be considered.
  • the circumference portion 11 is partially cut out while the shape of the cut-out portion is made to match with the shape of the contact surface of the thumb that touches during opening. Accordingly as shown in FIG. 17 and FIG. 18 , the operation of inserting the user's finger into the opening knob 34 becomes easy, so that not only the opening operation for the opening knob 34 is easy but also the lowering of sealability due to the circumference portion 11 is prevented.
  • FIGS. 29 to 34 illustrate cutting lines or breaking lines formed on the circumference portion on the opposite side of the cut-and-open portion of the bottle cap according to the second embodiment.
  • a cutting line 11 c having the inner circumference cut out so as to have a thickness thinner than the other portions from the bottom end of the circumference portion upward to a predetermined length.
  • Such a cutting line 11 c has an advantage that it can play a role as tamper indication portions because it is broken when the user opens the bottle cap.
  • a cutting line 11 d can be formed on the outer surface of the circumference portion 11 of the first cap.
  • a breaking line 11 e in which the bottom end is partially cut upward to a predetermined length and punched in a dotted-line form, can also be formed on the circumference portion 11 of the first cap as shown in FIG. 34 .
  • Such a breaking line 11 e has an advantage that it can give the feeling of being broken more clearly than the cutting lines when opening the bottle cap.
  • the present invention can be used as a bottle cap which has high enough sealability to be adopted in bottles accommodating carbonated beverages, can be opened by simple operation, is environmentally friendly and is low in manufacturing costs.
