Description

Cap assembly for spout < RTI ID = 0.0 >

The present invention relates to a spout cap assembly, and more particularly, to an assembly of a cap for a spout having an improved structure to prevent the cap from being detached separately even with the cap removed from the spout.

The spout pouch is formed in a structure in which a spout for injecting and discharging the contents is connected to an upper side of a pouch container made of a synthetic resin or the like and a spout cap is detachably coupled to the spout, .

The pouch container receives the contents, and the contents move outward through the pipe of the spout. The cap is for opening and closing the opening of the spout and is generally screwed into a thread formed on the spout.

Such a cap includes a band-shaped ring at the lower end of the cap to ensure a sealed state of the spout, and a user can confirm whether the cap is opened by checking the state of separation between the cap and the ring. In addition, the ring is configured to be caught by a protruding engagement protrusion on the outer peripheral surface of the spout tube, thereby preventing the ring from being separated from the tube due to the gap between the spout tube and the ring.

However, according to the conventional spout pawl, when the cap and the ring are engaged, the ring is not caught by the pawl, but when the cap is opened from the spout, the ring is easily detached. In this case, the ring is often separated from the spout and mixed into the contents while tilting the spout pouch and holding the contents in a separate container.

In order to solve such a problem, a method has been proposed in which the shape of the latching protrusion is formed in two stages so that the inner protrusion of the ring is caught between the latching protrusions and is not easily released (refer to the prior patent reference 1) As described above, when the locking protrusion is doubly formed, it is possible to form a locking protrusion at an accurate interval so that the double locking protrusion can be horizontally formed by the molding characteristics of the plastic, Because of the difficulties, it is not an effective solution.

Also, according to the conventional spout fauge, the problem of loss of the cap when the cap is detached from the ring occurs quite frequently. The separated cap usually has a cylindrical shape that is easy to roll in a small size. If the cap is not carefully taken care of, the cap is lost and the contents contained in the spout pouch are left unsealed.

However, considering that the contents of the spout pouch are foods such as sauces, it can be seen that it is practically difficult to carefully manage such caps in the cooking process. In this situation, the spout pouch in which the contents are left is left in an unsanitary sealed state by an inappropriate material such as toilet paper or vinyl.

In order to solve these problems effectively, it is urgent to introduce a spout cap having an improved structure to prevent detachment of the cap and ring from the spout and sanitarily manage the contents of the spout pouch.

Referring to FIG. 1, a spout pouch 1000 includes a pouch container 100, a spout 200 coupled to a portion of the pouch container by heat pressing, and a spout cap assembly 300 according to an embodiment of the present invention do.

The pouch container 100 may be a known pouch container for storing the contents therein. Also, the pouch container 100 may be formed of a material of a well-known pouch container. For example, the pouch container 200 may be formed by sealing the edge of the butted synthetic resin sheet. In the present invention, It is not limited.

The spout 200 includes a cylindrical tube 210 having both sides opened to allow the fluid to move, a plurality of sealing rings 220 formed to connect the spout 200 to the pouch container 100, And includes a plurality of threads 230 and a locking protrusion 240 formed to allow the assembly 300 to be fastened.

The tube 210 is formed to move fluid, including an outer end open to communicate with the outside of the pouch container 200 and an inner end open to communicate with the inside of the pouch container 100.

A plurality of sealing fins 220 project from the outer circumferential surface of the tube 210 at the inner end side of the tube 210. The sealing ring 220 is preferably formed by vertically protruding from the outer circumferential surface of the tube 210 where the pouch container 100 is adhered by heating.

The threads 230 project outwardly from the tube 210 to allow the cap 310, described below, to be screwed into the spout.

The latching protrusion 240 is formed to protrude annularly from the lower end of the outer circumferential surface of the spout. The locking protrusion 240 is formed so that the upper end of the ring 320 to be described later is caught by the lower end of the locking protrusion 240. The locking protrusion 240 serves to fix the position of the ring 320 so that the cap 310 is not detached from the spout 200 even when the cap 310 is separated from the spout 200. The protruding degree of the locking protrusion 240 can be set in consideration of the diameter of the ring 320 to be described later.

The spout 200 may be formed by injection molding. Therefore, the spout 200 of the present invention may be formed of a known synthetic resin material integrally formed with the tube 210, the sealing ring 220, the thread 230, and the locking protrusion 240. In the present invention, the material and the forming process of the spout 100 are not particularly limited.

2, the spout cap assembly 300 of the present invention includes a cap 310 that is openably and closably attached to the spout 200, a band-shaped ring 320 disposed at the lower end of the cap 310, A connecting band 330 for connecting the cap 310 and the ring 320 and a connecting rib 340 for preventing the cap 310 from being detached from the ring 320 in a packaged state.

The cap 310 is openably and closably attached to the spout 200 while sealing the open outer end of the spout 200. The cap 310 is configured such that its inner circumferential surface is in close contact with the outer circumferential surface of the spout.

The cap 310 may be formed with a thread 311 corresponding to the thread 230 of the spout 200 so as to be screwed into the thread 230 formed on the spout 200 on the inner side. The outer surface of the cap 310 may be provided with a ratchet-shaped concavity and convexity that can prevent slippage when being held by a hand during the opening operation.

The ring 320 is formed in the shape of an annular band or band and is provided at the lower end of the outer peripheral surface of the spout 200. Specifically, the ring 320 is positioned at the lower end of the locking protrusion 240 and is arranged to be caught by the lower end of the locking protrusion 240.

3, a locking piece 211 is formed on the outer circumferential surface of the tube 210 so as to protrude outwardly from the outer circumferential surface at predetermined intervals. The locking protrusions 211 are formed in the inner circumferential surface of the ring 320 so as to protrude inwardly And a piece 321 is formed.

3, when the cap 310 is lifted up on the thread 230 of the spout 200, the cap 310 is effectively separated from the ring 320, . That is, the ring 320 is fixed so as not to turn out from the spout 200 while the retaining piece 321 of the ring 320 and the retaining piece 211 of the pipe 210 are engaged with each other, and only the cap 310 is fixed to the spout 200 So that the connecting rib 340 connecting the cap 310 and the ring 320 is torn.

3, the engaging piece 321 of the ring 320 is shown to be rotated in the counterclockwise direction but not in the clockwise direction while being caught by the engaging piece 211 of the tube 210. However, The shapes of the first and second plates 211 and 321 are illustrative. The engagement piece 211 of the pipe 210 and the engagement piece 321 of the ring 320 may be configured to be engaged with each other or may be structured such that friction acts on the outer peripheral surface of the pipe 210 and the inner peripheral surface of the ring 320, The present invention is not limited to that shown in Fig.

3, when the shape of the tube 210 and the ring 320 is formed, the ring 320 does not appear at the lower end of the outer circumferential surface of the spout 200, The cap 310 connected to the spout 200 also has an effect of not covering the spout 200. Specifically, the retaining piece 321 of the ring 320 is configured to rotate along the lower end of the outer circumferential surface of the tube 210 when an external force equal to or greater than a predetermined magnitude is applied. When an external force less than a predetermined size is applied, 210 of the first embodiment. The ring 320 can be prevented from turning (or revolving) from the outer circumferential surface of the spout 200 when the ring 320 is subjected to an external force less than a predetermined magnitude, It is possible to prevent the cap 310 connected thereto from revolving. This will be described later in detail with reference to FIG.

The connecting band 330 connects the cap 310 and the ring 320. The connecting band 330 serves to prevent the cap 310 from being detached from the ring 320 even when the cap 310 is separated from the spout 200 while the outer end of the spout 200 is opened.

The connecting band 330 may be formed by the cap 310 and the ring 320 so that they are not separated from the cap 310 and the ring 320 when the user rotates the cap 310 to open the cap 310 from the spout 200. [ (Not shown).

The connection rib 340 is formed at a predetermined interval at a lower end of the cap 310 and is also connected to the ring 320 so that the cap 310 and the ring 320 are integrated.

The connecting rib 340 is formed to secure the sealing state of the cap 310 and the spout 200. When the cap 310 is rotated to open the cap 310 from the spout 200, The connecting ribs 340 are torn by separating the cap 310 and the ring 320 by raising the threaded portion 311 along the threads 230 of the tube 210.

The cap assembly 300 of the present invention may be formed by injection molding as in the case of the spout 200 described above. The known synthetic resin material may integrally include a cap 310, a ring 320, a connecting band 330, The connection rib 340 may be formed. However, the present invention is not limited thereto, and the material and forming process of the cap assembly 300 in the present invention are not particularly limited.

Hereinafter, with reference to FIG. 4, the effect of using the spout cap assembly 300 of the present invention will be described in detail. Here, for the sake of explanation, the drawings and reference numerals of FIG. 3 are referred to.

4 is a front view schematically illustrating an exemplary view of the use of the spout pouch shown in Fig.

4 (a) and 4 (b), the cap 310 is connected to the ring 320 so that even when the cap 310 is separated from the spout 200, 320, respectively. 4 (a) shows a state in which the ring 320 is formed on the outer circumferential surface of the tube 210 of the spout 200 (or a state in which the ring 320 revolves) because the engagement ring is not formed on the ring 320 described above And Fig. 4 (b) is a view showing a state in which a retaining piece is formed on the ring 320 so that the ring 320 is not turned over to a desired state by the user.

The ring 320 and the tube 210 may be formed as shown in FIG. 3 in order that the ring 320 is configured so as not to be exposed as shown in FIG. 4 (b). In other words, when an external force equal to or greater than a predetermined magnitude is applied, the ring 320 is configured to rotate along the lower end of the outer circumference of the tube 210, and when the external force less than a predetermined magnitude is applied, So that the ring 320 can be prevented from being in a state in which the ring 320 is out of the pipe 210 (or in a state in which the ring 320 is revolving).

Here, it is preferable that the predetermined magnitude of the force is larger than the magnitude of the torque applied to the ring 320 by the weight of the cap 310. 4 (b), when the ring 320 rotates from the tube 210 due to the own weight of the cap 310, when the cap 310 rotates from the tube 210 as shown in FIG. 4 (b) The ring 320 must be prevented from being rotated by the rotational force applied to the ring 320 by the own weight of the cap 310. [

3, the outer circumferential surface of the tube 210 and the inner circumferential surface of the ring 320 are slightly spaced apart from each other. Alternatively, the outer circumferential surface of the tube 210 and the inner circumferential surface of the ring 320 are in contact with each other, .

At this time, if friction is applied between the outer circumferential surface of the tube 210 and the inner circumferential surface of the ring 320, the ring 320 can more effectively prevent the state (or the idle state) from the tube 210, The technical features of the present invention as shown in (b) of FIG. 4 can be more easily implemented.

The use of the cap assembly 300 according to the present invention can solve the problem that the cap 310 and the ring 320 are separated from the spout pouch 1000 by including the connecting band 330 unlike the conventional spout pouch . Therefore, the conventional problem of the loss of the spout cap can be completely solved, so that even if the spout pouch 1000 is used repeatedly, the contents 1 stored in the spout pouch 1000 can be hygienically stored and managed .

The cap assembly 300 according to the present invention can prevent the rotation of the ring 320 when the spout pouch 1000 is tilted to move the contents to a separate container, It is possible to effectively solve the problem of contamination.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit or scope of the present invention as defined by the following claims. You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
