Hereinafter, with reference to the accompanying drawings will be described in more detail the bottle cap according to the present invention, the cold and hot water combiner and the mold for producing the cap according to the present invention.

The bottled water container cap described below is a sealing cap coupled to the lower end side of a bottled water container to be connected to a cold / hot water machine or the like, and a portion to be inserted into the cold / hot water machine is defined as a lower side based on a state in which it is disposed. The cold / hot water machine may be of various shapes and types as long as it has a water inlet pipe coupled with the water bottle cap as described later.

FIG. 2 is a side view showing a living water container cap according to the first embodiment of the present invention, and FIG. 3 is a perspective view of the living water container cap of FIG. 2.

The water bottle cap according to the present invention basically comprises a substantially cylindrical body portion 110 having an opened upper side, a bottom portion 120 closing the lower side of the body portion 110, And a flow stopper 140 that opens and closes the upper end of the insertion part 130. The insertion part 130 of the insertion part 130 is formed in a substantially cylindrical shape, The tab portion 122 is broken by a predetermined mechanical force to form a folded portion 121 to form a predetermined opening.

The lower end of the living water container (10 of FIG. 1) is formed in an open shape. The cap 100 closes the lower end of the living water container to prevent foreign matter from flowing in the movement and coupling process, .

In addition, the cap 100 in the coupling process between the bottled water and the cold and hot water container is opened so that the predetermined portion of the lower end side is in communication with the storage tank (20 in Fig. 1) inside the cold and hot water container of the bottled water contained in the bottled water container.

The cap 100 is formed of an approximately cylindrical body portion 110 forming a side wall and a bottom portion 120 coupled to a lower side of the body portion 110 to form a bottom surface, which is used in the prior art. The bottle cap is often made of only the body portion and the bottom portion. However, in the case of such a shape, there is a high possibility that the inflow of foreign matter or leakage occurs during the moving process or the detachment process with the cold / hot water machine. As a result, the bottom part 120 is protruded upward, An insertion portion 130 forming a flow tube is formed.

The body 110 is joined to the lower end side of the bottled water vessel from the inner circumferential side.

The insertion portion 130 is formed in a hollow cylindrical shape protruding upward from the substantially central portion side of the bottom portion 120 and is generally accommodated in the lower side of the inner peripheral space of the body portion 110 to function as a communication tube .

The lower side of the insertion portion 130 is opened and closed by the folded portion 121 formed on the lower side of the central portion of the bottom portion 120 and a predetermined opening is formed on the upper side as described later.

The upper side of the insertion portion 130 is opened to communicate with the interior of the bottled water, the open upper end side is opened and closed by a flow stopper 140, which is a separate member.

The flow stopper 140 may be selectively formed as long as it can open and close the upper end of the insertion part 130. However, as described later, the flow stopper 140 may be opened / closed by the inlet pipe 130 It is preferable that the insertion portion 130 has a size and a shape in which the outer circumferential surface is closely attached to the inner circumferential upper end side of the insertion portion 130. [

Specifically, the flow stopper 140 has a substantially cylindrical shape with its bottom opened, and its outer peripheral surface is in close contact with the inner peripheral surface of the insertion portion 130. The lower end of the upper end of the flow stopper 140 is preferably in close contact with the upper end of the inserting portion 130 for sealing inside the living water container. Accordingly, the upper end portion of the flow stopper 140 has a flat plate- .

A predetermined step or groove (not shown) may be formed in the side wall of the flow stopper 140 for fastening the insertion stopper 130 to the insert 130. The step or groove may be formed on the outer circumferential side of the insert 130 And the like, thereby enhancing the bonding force.

Further, in order to improve the reliability of sealing between the flow stopper 140 and the insertion portion 130, a substantially ring-shaped protrusion may be further disposed on the outer peripheral side of the flow stopper 140, and the ring- Or more may be disposed.

4) is inserted into the inner circumferential side of the insertion part 130, it is preferable for the sealing of the outer circumference of the inlet pipe 210 to be closely attached to the inner circumference of the insertion part 130. However, Since the outer circumference of the water inlet tube 210 is not in close contact with the inner circumference of the insertion section 130 as described later, the sealing section 131 having a narrower radius is formed on the upper end side of the insertion section 130 . Therefore, the sealing part 131 can further improve the adhesion with the water inlet pipe 210. Various embodiments relating to this structure will be described later.

The folded portion 121 is formed as a part of the bottom portion 120 so that the bottom of the insertion portion 130 can be closed as described above. That is, the folded portion 121 refers to a portion where the insertion portion 130 of the bottom portion 120 is disposed, and may be variously applied depending on the position and size of the insertion portion 130. [

The folding section 121 serves to prevent foreign matter from flowing into the insertion section 130 between the storage and movement of the bottled water container. When the folding section 121 is combined with the cold / hot water supply device, the inlet pipe (210 in FIG. The tab 122 may be formed to have a predetermined groove so that the tab 122 can be easily broken in the process of being inserted into the groove 130. [

The tab portion 122 is formed to have a smaller thickness than the other portions of the bottom portion 120 and the folded portion 121 to facilitate breaking of the folded portion 121. The tab portion 122 of the folded portion 121 is broken and separated into four pieces in the process of inserting the inlet pipe 210 . However, it is needless to say that the shape of the tab portion 122 can be selectively made as long as the folded portion 121 can be easily broken.

As the number of the tab portions 122 increases, the insertion of the water inlet pipe 210 is advantageous. Specifically, when the tab portion 122 is formed of three straight lines, the folded portion 121 is formed into six pieces by the inlet pipe 210 and is inserted into the insertion portion 130. The number of the pieces It is natural that the folding on the connecting portion with the bottom portion 120 becomes natural, so that the resistance due to the friction in the insertion process of the inlet pipe 210 can be reduced.

It is preferable that the body 110, the bottom 120, the folding unit 121 and the insertion unit 130 of the cap 100 are integrally formed and that they are formed as an injection-molded article of a resin material desirable.

In the concept of the present invention, the insertion portion 130 of the cap 100 is opened and closed by the flow stopper 140 from the upper side and has a double closed structure in which the lower portion is closed by the folded portion 121, The folded portion 121 is formed as a part of the bottom surface portion 120. [ As described above, when the lower end portion of the insertion portion 130 is closed with a separate plastic material sanitary label, a separate production and adhering process is added, so that the manufacturing process takes much time and effort. In the present invention, the closing of the lower end portion of the insertion portion 130 is made as a part of the bottom portion 120, so that the production process can be remarkably simplified as described later with reference to FIG. 9, It is possible to prevent the occurrence of unnecessary foreign matter in the process of detaching the container.

4 and 5 are side cross-sectional views illustrating embodiments of the bottled water cap of the present invention.

2, when the insertion tube 130 has a cylindrical shape with a substantially constant diameter and a water tube 210 having a substantially cylindrical shape is inserted into the insertion portion 130, There is a possibility that the tab portion 122 of the insertion portion 130 is broken and the undesirable friction is generated in the process of being rolled up to the inner circumferential side of the insertion portion 130 together with the water inlet tube 210, An unnecessary clearance may be generated between the inner circumferential side and the water inlet pipe 210, which may hinder the sealing.

Therefore, in the examples of Figs. 4 and 5, there is shown a structure capable of forming predetermined accommodating spaces in which the folded portion 121 can be received on the inner circumferential side of the insertion portion.

4, the side wall portion is inclined so that the radius of the insertion portion 130a increases toward the lower side. The tab portion 122 of the folded portion 121 is broken by the upper end portion of the water inlet tube 210 and is pushed up to form a predetermined receiving space 123a on the lower side.

Specifically, the water inlet pipe 210 may have a substantially cylindrical shape with a predetermined radius. Since the inner diameter of the lower portion of the insertion portion 130a is larger than the outer diameter of the water inlet pipe 210, And a space in which the folded portion 121 can be received by a predetermined height from the lower side is formed therebetween.

At this time, the inner circumference of the upper end of the insertion portion 130a is closely contacted with the outer circumferential surface of the inlet pipe 210 to provide sealing. In order to further improve the reliability of the sealing, the sealing portion 131 may have a substantially cylindrical shape with an inner radius of a predetermined height corresponding to the outer diameter of the water inlet pipe 210.

The inlet pipe 211 coupled to the cold / hot water machine (not shown) is formed with a water inlet 211 through which the bottled water accommodated in the bottled water container (not shown) can be introduced into the cold / And functions as an opening of a predetermined communication path formed inside the water inlet pipe 210.

A pressure regulator 212 may further be formed adjacent to the inlet 211 of the water inlet pipe 210. The pressure regulator 212 allows external air to be introduced into the water container, The flow of water through the inlet 211 is regulated.

The water communication channel (not shown) inside the water inlet pipe 210 communicating with the water inlet 211 and the air communication channel (not shown) inside the water inlet pipe 210 communicating with the pressure regulator 212 are mutually separated The water-communicating passage is structurally preferable to be located on the inner circumferential side of the air communication passage.

The inlet pipe 210 may further include an inner main pipe (not shown) spaced apart from the inner circumferential side by a predetermined distance, and a space between the inner main pipe and the inlet pipe 210 is connected to the pressure regulator 212 And the inner circumferential side space of the inner main pipe may be communicated with the inlet 211. However, the arrangement of the inlet 211, the pressure regulator 212, the water communication passage, and the air communication passage may be varied.

It is preferable that the water inlet pipe 210 has a shape in which the radius of the end face gradually narrows at the upper end side in order to break the folded portion 121 and to engage with the flow stopper 140. Although the upper end side has an approximately circular cross section in arc or semicircular shape, it is needless to say that the shape can be selectively made. The top end of the water inlet pipe 210 may have a quadrangular pyramid or a polygonal pyramid shape so that the folded portion 121 can be easily broken.

Referring to the coupling process of the water inlet pipe 210, as described above, when the bottom of the folded portion 121 forming a part of the bottom of the cap 100 in contact with the upper end side of the water inlet tube 210 in the weight of the bottle The upper end of the water inlet pipe 210 is applied to the bottom of the folded portion 121 by the pressure of the bottom, and the tab portion 122 formed in the folded portion 121 has a thinner cross section, so that fracture occurs along this portion. .

The folding unit 121 is pushed upward along the side of the water inlet pipe 210 while the water inlet pipe 210 is relatively lifted up from the inner circumferential side of the insertion unit 130. As described above, The space 123a is formed between the inner periphery of the insertion portion 130a and the outer periphery of the water inlet pipe 210 and the folded portion 121 is formed in the accommodation space 123a without interfering with the insertion of the water inlet pipe 210. [ Respectively. When the upper end side of the water inlet tube 210 comes into contact with the flow stopper 140, the upper end side of the water inlet tube 210 is inserted into the insertion opening 142 of the flow stopper 140, The flow stopper 140 is disengaged from the insertion portion 130a and is lifted together with the water inlet pipe 210.

The flow stopper 140 is lowered together with the lowering of the water inlet pipe 210 and the flow stopper 140 is inserted again into the insertion part 130a, The insertion portion 130a and the flow stopper 140 are rejoined to each other. When the water inlet tube 210 descends and completely disengages from the insertion portion 130a, the bottled water container can be sealed again by the flow stopper 140.

Also, as shown in the drawing, it is preferable that a radius of the outer circumference is smaller than an inner diameter of the insertion portion. Specifically, the flow stopper 140 has a shape corresponding to the inner diameter of the upper end of the insertion part 130. The upper end of the water intake pipe 140 may be formed to have the flow stopper 140 It is preferable that the horizontal step of the joining portion corresponds to the thickness of the flow stopper 140 in order to ensure the recombination of the flow stopper 140 and the insertion portion 130 in the separation process.

Meanwhile, in order to improve the ease of recombination of the flow stopper 140 in the process of recombining the flow stopper 140 and the insertion portion 130a, the upper end of the insertion portion 130a may have some clearance. That is, although not shown in the drawing, the upper end of the insertion portion 130a may have a larger radius than the sealing portion 131.

It should be noted that the shape for coupling and disengaging the inlet pipe 210 and for re-coupling the inlet and the flow plug may be applied to all embodiments described in the present invention.

5 is a side cross-sectional view illustrating a bottled water cap according to a third embodiment of the present invention. As in the case of the second embodiment, when the folded portion 121 can be received from the lower side to the inner circumferential side of the insertion portion 130b A receiving space 123b is formed.

In FIG. 5, the side of the insertion portion is inclined, but in the third embodiment, a predetermined stepped portion 132 is formed.

The height of the stepped portion 132 is set such that the folded portion 121 is raised to a height larger than the radius of the sealing portion 131 formed on the upper side, The height can be considered.

The shape of the sealing portion 131 can be maximized, which means that the sealing portion 131 can be more closely adhered to the water inlet pipe 210, which further enhances the sealing reliability.

According to this concept, there is an advantage that the accommodating space 123b in which the folded portion 121 is accommodated can be disposed more efficiently.

In the second and third embodiments of the present invention, the side of the insertion portion 130a is formed to have a shape having an inclined shape and a step portion 132, It is needless to say that various shapes such as arcs or polygons can be applied.

6 is a side sectional view showing first and third embodiments of the water inlet pipe of the present invention.

6 (a) shows an example in which the side wall portion of the water inlet pipe 210 is inclined. The inlet pipe according to the embodiments of the present invention can be variously applied to the inlet pipe shown in Figs.

When the water inlet pipe 210a is applied to the insertion portion 130a according to the second embodiment of FIG. 4, the inclined angle of the side wall portion of the water inlet pipe 210a is adjusted Is larger than the tilted angle of the portion 130a.

The sealing portion 131 may have an inner circumferential surface corresponding to the shape of the water inlet pipe 210a.

In Fig. 6B, an example of the water inlet pipe 210b according to the second embodiment is shown. The upper and lower sides of the water inlet tube 210b have different radii, and a step 213 is formed at the connection site.

The present invention also has a structure capable of forming a predetermined accommodation space in order to solve the problem that the folded portion is interrupted between the inlet pipe and the insertion portion and causes instability of the sealing, .

The bottled water cap according to the embodiments of the present invention has the advantage of leading to the simplification of the mold in the production process, which will be described in detail below.

8 is a side sectional view showing an example of a mold for molding a bottled water cap of the prior art.

The upper mold 30 is arranged so as to have the shape of a body and the lower mold 40 is arranged at a position closer to the central portion than the central portion The cap 11 is formed by injecting the injection material through the injection port 42 in a state in which the cap 11 is disposed so as to have a projection protruding through the insertion part.

The upper mold 30 and the lower mold 40 are separated from each other to allow the cap 11 to be separated from the upper mold 30 and the lower mold 40. When the upper mold 30 and the lower mold 40 are separated from each other in the vertical direction, There is a problem in that separation of the lower mold 40 and the cap 11 is not easy because the protruding portion 41 formed in the mold 40 is kept inserted into the insertion portion.

In addition, in the prior art, the injection port 42 is arranged to be eccentrically spaced to some extent from the center axis of the mold because the insert has a structure of passing through. Therefore, there is a possibility that injection of the injection material may not be uniform, and in this case, there is also a need to arrange a plurality of injection ports for uniform injection. In addition, when the mold is separated from the cap 11, an injection material at a portion corresponding to the injection port 42 remains in the cap 11 as a predetermined protrusion.

9 is a side view showing a mold of a bottled water cap according to an embodiment of the present invention.

In the embodiment of the present invention, since the bottom surface of the cap 100 has a flat shape, the bottom surface of the lower mold 400 becomes a kind of container having a flat shape.

The upper mold 300 has a protrusion 310 corresponding to the inner circumference of the insert 130 on the center side and the insert 130 is formed as an insert along the outer circumference of the protrusion 310.

The protrusion 310 may further include an outer circumferential portion 311 spaced apart from the outer circumference of the protrusion 310 and being a substantially ring-shaped protrusion to form the shape of the insertion portion 130.

An injection port 320 for injecting an injection material may be formed through the lower mold 400. The injection port 320 may be disposed eccentrically from the substantially center side or may be disposed at the center. In this case, when the lower mold 400 and the upper mold 300 are in close contact with each other, when the injection material is injected through the injection port 320, the cap 100 may be uniformly formed while being radially spread.

Since the bottom portion of the lower mold can be formed in a flat shape due to the structure of the mold for producing the cap according to the embodiment of the present invention, it is simple in structure and has an advantage that the injection objects can be arranged evenly. In addition, unlike the prior art, since the bottom surface of the insertion portion is not penetrated, it has a flat-plate-like structure, which makes it possible to easily separate the mold from the cap.
