Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wine utensils, in particular to a liquid outlet part and an inner component including the same. Background Art
[0002] The bottle cap is used to seal the bottle. According to different functions, there are bottle caps with different shapes and operation methods. For example, the mineral water bottle cap is circular and is screwed, and the canned beverage bottle cap is annular and is pulled. The white wine bottle cap is quite different from the conventional bottle cap due to its requirements for tightness, anti-theft and aesthetics.
[0003] The existing white wine bottle caps generally have the following three structures:
[0004] First, as Figure 1 shown, it is a cross-sectional view of the first type of bottle cap in the prior art. The bottle cap includes an outer cap, a fixing member and an inner plug. The inner plug is made of PE material. However, due to the relatively soft material of PET, it will become soft when soaked in hot water, making the bottle cap easy to be pulled off from the wine bottle. The outer cap is generally made of PP material, and the fixing member is made of PET or PC material. Since the inner plug is placed inside the fixing member, when pouring wine, the white wine flows out from the inner plug and then pours out after passing through the opening of the fixing member, that is, the white wine will contact the fixing member. Since the fixing member needs to be made of PC plastic, although in general, PC material is considered safe because it has the characteristics of non-toxic, high temperature resistance and acid and alkali resistance, for white wine, according to the latest industry regulations in the white wine industry, long-term contact or heating may accelerate the release of harmful substances in PC plastic. Moreover, the alcohol in white wine can promote the dissolution of chemical substances in the plastic into the wine, which may affect the quality and safety of the wine. Generally speaking, although PC material water cups are safe in general, in order to ensure the quality and safety of white wine, it is recommended to avoid using PC material containers to directly contact white wine.
[0005] For example, in Standard No. GB4806.7, serial numbers 32, 87, 113, etc. all specify that PC material shall not be used to contact foods with an ethanol content exceeding 50% (volume fraction), and for example, in Standard No. GB4806.7, serial numbers 77 and 81, or in Standard No. GB4806.11, serial number 28 all specify that PET materials and products shall not be used to contact carbonated beverages, beer and foods with an ethanol content exceeding 25% (volume fraction).
[0006] Second, as Figure 2 shown, it is a cross-sectional view of the second type of bottle cap in the prior art. The structure and materials of the second type of bottle cap in the prior art are the same as those of the first type. The bottle cap also includes an outer cap, a fixing member and an inner plug. The fixing member is made of PC plastic, and the inner plug is made of PE material. Only the structure of the inner plug is different, but the inner plug is also placed inside the fixing member, and the same problems as the first type of bottle cap will also occur.
[0007] The specific structure of the bottle cap of this prior art can refer to the technical solution disclosed in Chinese patent CN216302010U: a double-sealing structure bottle cap, including an inner cover and a bottle sleeve, the bottle sleeve is installed on the inner cover, the top of the inner cover is provided with a tight part protruding upward, the inner side of the bottle sleeve is provided with tight grooves for installing the tight part and the number is the same as and one-to-one with the tight part, the tight part is installed in the tight groove to form a first sealing structure, the first sealing structure is also provided with a first sealing gap between the tight groove and the tight part, the outer lower edge of the inner cover is provided with a sealing sleeve, the sealing sleeve and the top surface of the first outer ring of the bottle sleeve are a second sealing structure, the second sealing structure is also provided with a second sealing gap between the sealing sleeve and the top surface of the first outer ring of the bottle sleeve, the inner cover is provided with an inner plug assembly connected thereto, and the inner plug assembly is composed of a plurality of inner plug components.
[0008] The third type, such as Figure 3 The figure is a cross-sectional view of the third bottle cap in the prior art. The bottle cap also includes an outer cover, a fixing piece and an inner plug. In order to prevent counterfeiting of liquor, a metal sheet is embedded in the fixing piece, so that the bottle cap is not easy to pull off. Although the third prior art solves the problem of easy counterfeiting in the first and second prior arts, the production cost is greatly increased due to the addition of the metal sheet design.

Specific embodiments
[0045] In combination with the accompanying drawings, a liquid outlet member provided by the present utility model and an inner component including the same are further described.
[0046] As shown in the figure, a liquid outlet member is assembled in an inner component of a white wine bottle cap. Among them, the inner component includes a fixing member 1 assembled at the bottle mouth of a bottle body adapted thereto, an outer cover 2 covering the fixing member 1, and an inner plug 3 provided inside the fixing member 1.
[0047] Specifically, the liquid outlet member 4 is made of a material that can contact white wine. The liquid outlet member 4 is disposed at the upper part inside the fixing member 1, and the upper mouth of the liquid outlet member 4 extends out of the upper mouth of the fixing member 1. The inner plug 3 is connected to the lower end of the liquid outlet member 4, and the lower end of the inner plug 3 is inserted into the bottle mouth of the bottle body.
[0048] Furthermore, both the liquid outlet member 4 and the inner plug 3 are hollow. When the liquid outlet member 4 and the inner plug 3 are in an assembled state, the hollow parts of the two are mutually communicated to form a diversion channel.
[0049] Furthermore, a drainage cavity 41 is opened in the upper part of the liquid outlet member 4. The drainage cavity 41 divides the upper part of the liquid outlet member 4 into a liquid outlet portion 42 and a liquid outlet ring sleeve 43, so that the liquid outlet portion 42 is surrounded by the liquid outlet ring sleeve 43 therein.
[0050] Further, four diversion holes 44 are formed on the side surface of the liquid outlet part 42, and the diversion holes 44 communicate with the drainage cavity 41.
[0051] Further, a step 45 is provided inside the liquid outlet part 4. The step 45 divides the liquid outlet channel of the liquid outlet part 4 into an upper channel 46 and a lower channel 47. The diversion holes are formed on the side wall of the upper channel 46, and the liquid outlet cavity 41, the liquid outlet part 42 and the liquid outlet ring sleeve 43 are all arranged outside the upper channel 46.
[0052] When the liquid outlet part 4 and the inner plug 3 are assembled in the fixing part 1, a diversion channel is formed in the hollow parts of the liquid outlet part 4 and the inner plug 3. When the bottle body is tilted to pour wine, the white liquor in the bottle body first flows in from the bottom opening of the inner plug 3, flows through the hollow channel of the inner plug 3 and then into the hollow part of the liquid outlet part 4, and then flows out after flowing through the diversion holes 44 and into the drainage cavity 41. During the whole process, the white liquor only contacts the liquid outlet part 4 and the inner plug 3 and does not contact the fixing part 1.
[0053] Embodiment 1, as Figure 4 shown, is a schematic diagram of this embodiment, Figure 4 and is a cross-sectional view of the assembled state of the liquid outlet part 4 and the fixing part 1 in this embodiment.
[0054] Further, the liquid outlet part 4 and the fixing part 1 are assembled by interference fit. When the liquid outlet part 4 and the fixing part 1 are in the assembled state, the outer surface of the liquid outlet part 4 and the inner surface of the fixing part 1 are tightly pressed and fitted together so that the liquid outlet part 4 cannot be separated from the fixing part 1.
[0055] Among them, the structures and assembly relationships of the fixing part 1, the outer cover 2 and the inner plug 3 are not limited in this embodiment, and only the sealing between the fixing part 1 and the liquid outlet part 4 and the sealing between the inner plug 3 and the liquid outlet part 4 need to be achieved.
[0056] Embodiment 2, as Figures 5 - 9 shown, is a schematic diagram of this embodiment, Figure 5 is a schematic structural diagram after the fixing part 1, the outer cover 2, the inner plug 3 and the liquid outlet part 4 are all assembled in this embodiment, Figure 6 and is a cross-sectional view of the above four components in the assembled state.
[0057] Among them, a pressing platform 11 is further provided inside the fixing part 1.
[0058] Further, a downwardly protruding pressing ring 21 is provided on the inner lower surface of the outer cover 2.
[0059] Further, a bent part 31 is provided on the outer surface of the inner plug 3.
[0060] Further, when the inner components are assembled on the bottle body, that is, when the fixing member 1, the outer cap 2, the inner plug 3 and the liquid outlet member 4 are all assembled, the upper part of the inner plug 3 is inserted into the lower part of the liquid outlet member 4. In this state, there are at least the following five surface contacts in the inner components to comprehensively achieve the sealing performance and firmness of the assembly of the inner components, so as to prevent the leakage of the white liquor in the bottle body or the loosening of the inner components. Specifically:
[0061] 1. The outer surface of the pressing ring 21 of the outer cap 2 contacts with the inner surface of the upper opening of the liquid outlet member 4 to form a seal;
[0062] 2. The upper outer surface of the inner plug 3 contacts with the lower inner surface of the liquid outlet member 4 to form a seal. More specifically, the upper outer surface of the inner plug 3 contacts with the inner surface of the lower channel 47 of the liquid outlet member 4 to form a seal;
[0063] 3. The upper surface of the bent portion 31 of the inner plug 3 abuts against the lower surface of the liquid outlet member 4;
[0064] 4. The upper surface of the bent portion 31 of the inner plug 3 abuts against the lower end surface of the pressing platform 11;
[0065] 5. The lower outer surface of the inner plug 3 contacts with the inner surface of the bottle mouth to form a seal.
[0066] As Figure 7 shown, it is a cross-sectional view of only the state where the liquid outlet member 4 and the fixing member 1 are assembled with each other. The liquid outlet member 4 and the fixing member 1 are fixed and limited in the form of a buckle member.
[0067] Specifically, a first fastening member is provided on the outer surface of the liquid outlet member 4, and a second fastening member is provided on the inner surface of the fixing member 1. When the liquid outlet member 4 and the fixing member 1 are in the assembled state, the first fastening member and the second fastening member cooperate with each other so that the liquid outlet member 4 cannot be separated from the fixing member 1.
[0068] Further, as Figure 8 and Figure 9 shown, Figure 8 it is a schematic structural view of the liquid outlet member 4 in this embodiment, Figure 9 and it is a cross-sectional view of the liquid outlet member 4 in this embodiment. Among them, the first fastening member is a ring groove 51 recessed from the outer surface of the liquid outlet member 4, and the second fastening member is a snap ring 52 protruding from the inner surface of the fixing member 1.
[0069] Further, the lower notch edge to the inside of the ring groove 51 is a horizontal first plane 511. At this time, the shape of the remaining inner wall surface of the ring groove 51 is not limited and can be arc-shaped. The cross-section of the ring groove 51 can also be a right trapezoid shape, as long as the bottom surface is set as the first plane 511. At the same time, the shape of the snap ring 52 is not limited, that is, the setting of the first plane 511 can realize the limitation of the snap ring 52.
[0070] Further, in order to better prevent the liquid outlet member 4 from separating from the inner plug 3, a first clamping ring 71 protruding into the channel is provided on the inner surface of the lower channel 47 of the liquid outlet member 4, and a second clamping ring 72 protruding outward is provided on the outer surface of the upper part of the inner plug 3. When the liquid outlet member 4 and the inner plug 3 are assembled, the first clamping ring 71 and the outer surface of the upper part of the inner plug 3 press against each other, and the second clamping ring 72 and the inner surface of the lower channel 47 of the liquid outlet member 4 press against each other. At the same time, the first clamping ring 71 is located below the second clamping ring 72. When the liquid outlet member 4 and the inner plug 3 are displaced up and down under an external force, the first clamping ring 71 and the second clamping ring 72 press against each other to prevent the liquid outlet member 4 and the inner plug 3 from separating from each other, thus also ensuring the sealing performance between the liquid outlet member 4 and the inner plug 3.
[0071] Embodiment 3. In this embodiment, the cross-sectional view of the liquid outlet member 4 and the fixing member 1 in the assembled state can be referred to Figure 7 as shown.

The difference between this embodiment and Embodiment 2 is only the structural difference of the clamping ring 52, which is specifically as follows:
[0072] The lower part of the clamping ring 52 is provided with a horizontal second plane 521. At this time, the shape of the remaining outer wall surface of the clamping ring 52 is not limited, and it can be arc-shaped. It is also possible that the cross-section of the clamping ring 52 is a right trapezoid shape, and only the bottom surface needs to be set as the second plane 521. At the same time, the shape of the annular groove 52 is not limited, that is, the setting of the second plane 521 can realize the clamping between the clamping ring 52 and the annular groove 51. Others are the same as those in Embodiment 2.
[0073] Embodiment 4, as Figure 10 shown, is the cross-sectional view of the liquid outlet member 4 and the fixing member 1 in the assembled state in this embodiment. Among them, the assembly relationship and assembly structure among the fixing member 1, the outer cover 2, the inner plug 3, and the liquid outlet member 4 are the same as those in Embodiment 2, and will not be elaborated here. The difference between this embodiment and Embodiment 2 is only the structural difference between the annular groove 51 and the clamping ring 52, which is specifically as follows:
[0074] The annular groove 51 is an arc surface from the upper notch edge to the lower notch edge, and the clamping ring 52 is an arc-shaped arched annular structure, that is, the clamping ring 52 is clamped in the annular groove 51, which can also prevent the fixing member 1 and the liquid outlet member 4 from separating from each other. Others are the same as those in Embodiment 2.
[0075] Embodiment 5, as Figures 11 - 14 shown, is the schematic diagram of this embodiment. The schematic diagram of the structure after the fixing member 1, the outer cover 2, the inner plug 3, and the liquid outlet member 4 are all assembled is as Figure 5 shown. The external structure is the same as that in Embodiment 2. The internal structure is as Figure 11 shown, Figure 11 which is the cross-sectional view of the above four components in the assembled state.
[0076] Among them, a pressing platform 11 is further provided inside the fixing member 1.

In this state, there are at least the following five surface contacts in the inner assembly to comprehensively achieve the sealing performance and firmness of the assembly of the inner assembly, so as to prevent the leakage of the white liquor in the bottle body or the loosening of the inner assembly. Specifically:
[0080] 1. The outer surface of the pressing ring 21 of the outer cover 2 is in contact with the inner surface of the upper opening of the liquid outlet member 4 to form a seal;
[0081] 2. The inner surface of the upper part of the inner plug 3 is in contact with the outer surface of the lower part of the liquid outlet member 4 to form a seal. More specifically, the inner surface of the upper part of the inner plug 3 is in contact with the outer surface of the lower channel 47 of the liquid outlet member 4 to form a seal;
[0082] 3. The upper surface of the bent portion 31 of the inner plug 3 abuts against the lower surface of the pressing platform 11;
[0083] 4. The outer surface of the lower part of the inner plug 3 is in contact with the inner surface of the bottle mouth to form a seal.

[0101] Among them, an inwardly bent fastening platform 61 is provided on the outer surface of the liquid outlet part 4, an outwardly protruding limiting ring 62 is provided below the fastening platform 61 of the liquid outlet part 4, and a limiting cavity 63 is formed in the limited area between the fastening platform 61 and the limiting ring 62. The fastening platform 61, the limiting ring 62 and the limiting cavity 63 constitute the first fastener, and the second fastener is a ring platform 64 protruding from the inner surface of the fixing part 1.
[0102] Furthermore, the protruding end of the ring platform 64 extends into the limiting cavity 63, so that when the liquid outlet part 4 and the fixing part 1 generate vertical displacement due to external force, the ring platform 64 can cooperate with the limiting cavity 63 to achieve the anti-disconnection effect.
[0103] Furthermore, in order to better prevent the liquid outlet part 4 from being separated from the inner plug 3, a first clamping ring 71 protruding into the channel is provided on the inner surface of the lower channel 47 of the liquid outlet part 4, and a second clamping ring 72 protruding outward is provided on the upper outer surface of the inner plug 3. When the liquid outlet part 4 and the inner plug 3 are assembled, the first clamping ring 71 abuts against the upper outer surface of the inner plug 3, the second clamping ring 72 abuts against the inner surface of the lower channel 47 of the liquid outlet part 4, and at the same time, the first clamping ring 71 is located below the second clamping ring 72. When the liquid outlet part 4 and the inner plug 3 generate vertical displacement due to external force, the first clamping ring 71 and the second clamping ring 72 abut against each other to prevent the liquid outlet part 4 and the inner plug 3 from being disengaged from each other, thereby also ensuring the sealing performance between the liquid outlet part 4 and the inner plug 3.
[0104] The present utility model has been illustrated and described by referring to the preferred embodiments. However, those of ordinary skill in the art should understand that various changes in form and details can be made within the scope of the claims.
